Description

Technical Field

[0001] The utility model relates to the technical field of beam bridges, in particular to an assembled cap beam bracket supporting tool. Background Art

[0002] A beam bridge refers to a bridge with beams or truss beams as the main load-bearing structure. When the upper structure is subjected to vertical loads, the supports only produce vertical reaction forces. As one of the basic bridge systems, beam bridges are very convenient to manufacture and erect, and are widely used. They account for a large proportion of bridge construction. A cap beam refers to a beam set on top of a pile pier to support, distribute and transfer the load of the upper structure. It is also called a cap beam. A beam made of reinforced concrete or lightly reinforced concrete is set on the piers or on the piles. Its main function is to support the upper structure of the bridge and transfer all the loads to the lower structure. Some piles are directly connected to the cap beam, while others are connected to the cap beam after connecting to the columns.

[0003] At present, there are two types of bracket supports used in the construction of the cap beam in the substructure of a beam-type bridge. One is to set a hoop on the pier body and use the friction between the hoop and the pier body to balance the upper construction load. The other is to embed steel bars in the pier body and use the shear resistance of the steel plate to balance the upper construction load. However, the contact stress between the bracket unloading device and the steel bar is relatively concentrated, which reduces stability. Therefore, an assembled cap beam bracket support tool is proposed to solve the above problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an assembled cap beam bracket support tool, which has the advantage of improving stability and solves the problem that there are currently two types of bracket supports used in the construction of the cap beam in the lower structure of a beam-type bridge. One is to set a hoop on the pier body and use the friction between the hoop and the pier body to balance the upper construction load; the other is to pre-embed steel rods on the pier body and use the shear resistance of the steel plate to balance the upper construction load. However, the contact stress between the bracket unloading device and the steel rod is relatively concentrated, which reduces the stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an assembled cap beam bracket support tool, comprising a pull-out steel, two connecting steels are placed on the front and back of the pull-out steel, and the top and bottom surfaces of the four connecting steels are fixedly connected with fixed steel plates.

[0006] A cap beam bracket unloading sand box is placed on the top surface of the fixed steel plate at the top, and two limiting steel plates are fixedly connected to the bottom surface of the fixed steel plate at the bottom. A steel rod is fixedly connected between the two limiting steel plates. A plurality of clearance holes are opened on the front of the withdrawal steel, and limiting holes are opened on the front sides of the four connecting steels. A screw with one end passing through the limiting hole and the clearance hole in sequence and extending to the back side of the back connecting steel is placed on the front side. Two nuts are threadedly connected to the outer peripheral wall of the screw.

[0007] Furthermore, the opposite side surfaces of the two fixed steel plates are respectively fitted with the top surface and the bottom surface of the withdrawable steel, and the withdrawable steel and the fixed steel plates are slidably connected.

[0008] Furthermore, the withdrawal steel and the connection steel are both I-shaped steels, and the four withdrawal steels and the connection steels are linearly and equidistantly distributed from front to back.

[0009] Furthermore, the thickness of the fixed steel plate and the limiting steel plate are both one centimeter, the length of the fixed steel plate is fifty centimeters, and the width is forty centimeters.

[0010] Furthermore, the screw rod and the limiting hole are clearance-matched, and the screw rod and the relief hole are clearance-matched.

[0011] Furthermore, the plurality of the clearance holes are linearly and equidistantly distributed from left to right, and the distance between two adjacent clearance holes is thirty centimeters.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] 1. This prefabricated cap beam bracket support tool forms a prefabricated component with a large force-bearing area by fixing steel plates, pulling steel and connecting steel. It is placed under the unloading sandbox of the cap beam bracket, increasing the contact surface between the steel rod and the unloading sandbox, reducing stress concentration at the support point and enhancing the stability of the support structure.

[0014] 2. The assembled cap beam bracket support tool can move the fixed steel plate through the sliding connection between the fixed steel plate and the withdrawal steel, thereby improving the use effect. The fixed steel plate can be conveniently restricted through the cooperation between the clearance hole and the screw, thereby improving the stability of the fixed steel plate. At the same time, the fixed steel plate can be fixed through the threaded connection between the nut and the screw, which is convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS
