A hold in palm on top for truss -like cast -in -place beam support

Technical Field

The utility model belongs to bridge, tunnel construction concrete pouring and structure mounting construction field, relates to cast-in-place construction a bracket is used, in particular to a truss type now-place the jacking of the bracket.

Background Art

The upper part of the existing structure-place often adopts the support construction. In the mountain and valley regions where the bridge is located in the terrain and geological reasons, now-polymer support packed support structure can not be adopted, the use of the large cross-steel pipe support structure, but the steel tube frame among the parts of the welding at the time of installation, in the difficulty when removed after the end of the construction of larger. The traditional process is generally directly cutting the steel pipe, or in a steel tube bracket set up as a temporary support for the use of the sand box, in order to remove the bracket after the end of the construction. Cutting the steel pipe, easy safety accidents, and waste of materials. Sandboxed because of its installation is not easy to adjust the elevation of the support structure, and therefore there is a certain limitation.

Content of the invention

The purpose of the utility model to the current cast-in-place liang bracket assembly and disassembly difficult problem, provides a current-place the jacking of the bracket, the bracket is arranged in the top of the column, by an assembling structure, convenient support for mounting and dismounting.

The technical proposal of the utility model are as follows:

For truss type now-place the jacking of the bracket, characterized in that comprises a base, the adjusting screw and the upper support plate, lower end of the base is provided with a 3 downward projecting the request inserts joint, each of the plug-in connector is a circular cylinder structure, close to the lower end of the cylinder is provided with an annular groove part, the upper end of the base is a positioning tube, the adjusting screw is inserted in the base of the lower end of the positioning tube, and through the adjusting screw nut, the upper end of the adjusting screw is fixed on the bottom surface of the upper support plate is connected with the, on the top surface of the supporting plate is provided with at least 4 and a locating pin protruding upward.

The utility model is simple in structure, convenient installation, the support can be set up when the fine adjustment of the elevation of the structure, the mounting precision of the structure can meet the need. The pouring construction after the end of the adjusting screw to reduce the height of the bracket can be realized remove, convenient and rapid, high safety. Can avoid repeated welding, assembling and disassembling the damage to the steel pipe, the steel pipe is safe and reliable, increasing the service life thereof, and can save the artificial, the economic benefits are obvious.

Mode of execution

As shown in Figure 1, the utility model comprises a base 1, the adjusting screw 2 and the upper supporting plate 3, the base 1 is provided with the lower end of the 3 downward projecting the request inserts joint 4, each connector 4 is a circular cylinder structure, close to the lower end of the cylinder is provided with an annular groove part 5, the upper end of the base is a positioning tube 6, the adjusting screw 2 is inserted in the base of the lower end of the positioning tube 6 in, and by adjusting the nut 7 is fixed, the adjusting screw 2 with the upper supporting plate 3 is fixedly connected with the bottom surface of the, the upper plate 3 arranged on the top surface of the at least 4 upwardly projecting locating pin 8.

The adjusting screw 2 with the upper plate 3 of the bottom surface of the connection mode can be connected by the bolts. In the bottom surface of the upper support plate is provided with two connecting plates 9, the adjusting screw 2 is provided along the upper end of the adjusting screw through the screw hole of the diameter, the adjusting screw 2 is the bottom surface of the upper end of the two connecting plates 9 between, and through the connecting bolts and the two connecting board is fixed.

As shown in Figure 2, the utility model is applied to the truss type now-polymer support, in particular to the triangle truss as the columns of the support. The utility model when in use, the triangular truss support column 10 at the top end, the base 1 of the 3 connector receptacle 4 are respectively inserted into the supporting column 3 in the steel pipe, the outer wall of the upright post steel pipe installation is LED to the steel pipe the fastening bolt 11, the fastening bolt 11 is inserted into the front end of the front end of the connector ring-shaped groove 5 in, utility model with the support column is fixed. The support of the upper supporting beam 12 is mounted on the jacking of the upper support plate 3 on, the upper support beam preset a plurality of pin holes, and the jacking plate through the pin hole and the top surface of the positioning pin 8 is inserted. In order to maintain the stability of the upper support beam, the top plate 3 with the upper supporting beam 12 can also be used between the fixed bolt clip 13 fixed.

The utility model on the support not only the support function, also can be used as a fine adjustment for the height of the bracket. The superstructure of the fixed after installation on the upright column, through the adjusting nut 7 adjusted in the screw 2 is screwed on the height, can control the adjusting screw 2 in the base positioning tube 6 inserted in length, thereby adjusting the height of the entire superstructure, thereby realizing the fine adjustment of the height of the bracket.

In order to prevent the adjusting nut 7 during the rotation of the adjusting screw 2 to rotate together, the adjusting screw can be arranged on the outer wall in at least two axial grooves along the adjusting screw 14. As shown in Figure 3, the positioning tube of the base 6 is provided with a on the inner wall of the adjusting screw 2 with the groove on the strip 15. The lower end of the adjusting screw and to support the base of the tube is inserted, the positioning tube 6 on the inner wall of the strip 15 into the groove on the adjusting screw 14 in, so that the adjusting screw for the axial rotation.
