Panel for construction.

The present invention relates to a method of making construction boards plastic and plastic, for use in exterior walls of a building, such as a cabin J or in the inner walls of a building, or as panel covering.

A construct containing blocks of thermal insulating material, separated by strips of steel reinforcing and sandwiched between layers of synthetic plastics material ., containing glass fiber mats, is know from British Patent n * 1324661 and the invention ' current is relates to a technique for manufacturing improved for this type of product Poultry, resulting in an improved product.

00 The n accordance with the first aspect of the invention, a method of making the building panel is provided containing:

a) pouring a first layer of viscous and ré6îne mixture charged into a mold open from above, determine the perimeter of the building panel;

b) harvesting the surface of the first layer;

c) permeable component and reinforcing on or in the first layer;

d) contacting at least one block of thermal insulator, or directly on the component enhances or on an additional layer of mixture poured onto the reinforcing element, with the breaches demarcated between the edges adjacent blocks and the mold§

allow the blocks adhere at enhancing component or to the additional layer; ^!

f) filling the breaches of cStés a viscous mixture;

g) applying further each amount of viscous mixture confectioneries the exposed upper surface of the insulating material, and picking the additional amount;

h) bringing more permeable component enhancing in or on the mixture harvested;

a final amount of the mixture ilappliquer at enhancing component, to end of submerge it in the mixture, picks up the final mixture; and

j) enabling the panel to obtain an initial rigidity sufficient to be able to remove the panel from the mold *

As to the second aspect of the present invention there are ^ a board produced in accordance with the disclosed method * gasoline, the panel sècompose two plates, each is component of a bond coating® covered with a reinforcing resin of both cQiâs dA "and together they squeeze the thermal insulating blocks" if the layers of the adhering to each other, all surrounding, by. the mixture worm® comstically in the breaches edges "this produces a sound panel" gricultural hitches solid and satisfactory resistance to forces bent Linkages, without the requirement for reinforcing metal components, as is taught in British Patent n * 1324681 J panel can be manufactured in large market place " for example 8 ft. the X 4 ft *, without a tendency to cambering *

Preferably, the mixture contains three parts by charging a resin filler. The former consists of silica sand convéniente manner, e.g. 90 mesh b. 8.5. or mesh of larger or smaller having their vision purposefully specific * the mixture, if it is made! Britain, would require addition of accelerator and catalyst, as is well known in the loom, to obtain the curing in a reasonable time. However, such additions are not necessary in warm regions. The mixture sabletrésine may be 6:1, but preferably (and for manufacture in Britain) a mixture of 3:1 is employed * whether to employ private mark uncured resin-accelerated this may request:

to) styrene monomer in an amount of 15 c/o resin

b) 0 * 5 cc accelerator 6% cobalt, per pound of mixture c) a catalyst (e.g. BUTANQX m50) in an amount of 4 this per pound|le mixture *,>.•

The amount of accelerator or catalyst "die" ^ will change during the temperature and the rate at which is requires the hardness of the object, and will be different from country to_; country, and day by day, being dependent on the temperature. ambient.

However, if requires a greater fluidity "for example to fill spaces edges, the mixture" at splits " may be of * 2 * 5:1

Despite that the enhancing component could be S metal gauze, Hessians, tissue or cloth with bag, it is preferable

to use glass fiber mats that can be easy -

2 centeredly wetted by the compounded resins, by. example 1 oz/TFs and N&assessm " would be hashed.

•despite that the insulating blocks may be a cellulose material, such as by. paperboard, cardboard or prefabricated form, the blocks synthetic plastics are preferred * it is also preferred that the block R.' isjsorte what sgiièxesoit treated so as th be fire resistant.

5i requiring that panel has qualities of weight holder, for example by forming part of an external wall a bungalow, which it needs to be both support the roof that isolate it from "the insulation can be provided by two or more individual blocks having their c6tés adjacent aceomodant e.g. a beam" 1" or bar track take place to extend vertically in use, between the top and bottom of the panel *

Alternately, insulating blocks expacés they can to be provided in such a way to be accommodated in the space (e) a conduit, for example for electrical service " water pipes, hoses and égoutement andc * and further, the lines formed by grooves they can to be prefabricated in the insulating block turn mimics *

If the panels with space between the insulation are required, then those gaps are filled substantially (up to the point where the spaces are not occupied by a beam "the I", flat bar or conduit) by mixing, at the same time as the spaces edges are filled *

If they are needed to construct houses " the panels would be flat and product modular measures, e.g. ôft the X * 4 ft. the X 2 ft and 8 ft ** and there is not probième incorporate in the process of modeling frameworks doors or as contrast fenêtrespas more that molding these parts in one operation by dedanà'd * a panel "because all it takes is to cut a hole in both components reinforcing, corresponding to the dimensions of the framework of door or sash window.. and the frames of the doors ATs windows are placed first at the bottom of the mold and the spaces Res.* ARF are filled with scum, mixing" of reinforcing " andc.

Preferably, if it relates to construction of houses, * bag for ensuring the structural stability and the imperméaMJUition corners of a house, a panel non-i flat, but in the form of "I", is provided. Thus the first esté of this panel can be molded with a mitered angled edge and the second side may also be molded with a mitered edge, touching at the first side edge tab molded. Preferably ', mats rubber-reinforcing glass fiber ", integral with each side, extend along the seams mitered and cover the latter * alternately, the first and the second side can have edges butted.

Then, if the panels are required th constructing bâtieees, the panels, they lie flat or to shape @

If the boards produced in accordance with the above-mentioned methods have not the desired thickness for the use contemplated, then

••, in accordance with another feature of the invention, there■3, 40: controlled without duplication using the technique described previously fabricatien, to obtain a laminate panel, composed of any number of fundamental panels. If requires quality s of fire resistance, the inner surface of the panel, it is to say the surface which will serve to I^I interior of a building, may be covered with a swelling, for example NULLIFIRE w3g.

The invention will be now described in greater detail,

by way of example, with reference to the accompanying drawings, in which: -

Fig. N.^I 1 is a diagrammatic sectional view through a mold open from above, for the manufacture of a building panel in accordance with the present invention;

Dane-drawings, a mold open top 1 contains a base 2, perimetric sides 3 and sides of ends 4 for the manufacture of a rectangular construction panel in accordance with the invention * 3 sides are attached to the base 2 by any means ans, for example: bolts, screws (not shown) to, and have an adjustable and/or are detachable to allow to manufacture panels of different measurements * in detail the base 2, the sides 3 and 4 may be naive tips the EFI wood, with the sides 3 having strips of capsular e engageable by a screed support surfaces (not shown) conventional *

As shown in Figure N.^I 1, a first layer 6 of viscous mixture of resin and filler is poured into the mold 1•if co * uche 6 is uneven, this is peeled off from a screed along the mold 1 throughout 4 at the other end, having the screed supported bands capsuling 5.

Then, as shown in Figure no. 2, a permeable member and net-like reinforcing fiberglass T is fitted on the first layer 6 *

Then, as shown in Figure N.^fl. 3, a block spa insulator 8, e.g. polystyrene, is carried, or directly on the mat 7 alternatively on an additional layer of mixture yexsée 7 on the mat, with a gap 9 defined by the adjacent edge of the block and the side 3_I This may be convénient, as detailed in Figure no. 3, employing multiple blocks 8, in this case 10 interstices are formed between adjacent edges of adjacent blocks, but whether to employ a single block:

or more will depend on the size of the panel making and dimensions of blocks available. Because the mat 7 is permeable thereof is wetted by the layer 6 and thus the block (e) optionally adheres had reinforcing mixture

The stage as is illustrated in Figure n-®&wherein interstices of 9 10 and any gap between adjacent blocks, if in use more, are filled with viscous mixture 11"

The stage as is shown in fig. no. 5, wherein an additional amount of viscous mixture 12 is applied to the exposed surfaces of the block (e) 8, the layer 12 is then tucked.

The stage as is shown in fig. n-®6, wherein additional component permeable reinforcing 13, . still in the form of fiberglass mat, is applied to the layer 12"

The stage as illustrated in figured the n®7 "wherein a final amount of mixture 14 is applied to the mat 13 to end of submerging thereof in the mixture, the layer 14 is greatly accelerated" as then tucked.

After allowing had panel reaching an initial hardening to fine to make possible the handling, the panel may be removed from the mold.

" Alternatively, as shown in^? 1 @ n-® fig. 8_? © uïî spall layer 15 stone Industry may applied to the layer 14, or immediately after the picked of the layer 14, or after allowing to layer 14 partially cure₀ As an alternative additional, splinters can Industry 15 applied to the panel removing it from the mold, e.g. @ n-applying another coat of mixture to the eouche 15, the fragments being retained by this new layer.

If it is the intention to employ the panels for the house building, then it will likely be necessary that the panels abut each other, edge to edge, and in this case it would be pre férable that one side is provided with an elongated groove * D. third chamber and that the sides are provided with a 3 oppbsée elongated tongue 17 so that built during the process of molding it

will automatically edges tongue and groove panel by the varse? s of the mixture 11",

In Figure no. 9 panel completed 18 is illustrated,, having, along the edge of one side a tongue 19 and edge of the other side, a groove 20, the panel containing conduits 21 e.g. for electricity cables and a beam^NRI^{the n} 22 if the panel must have qualities of load carrier *
