Description

Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to a support frame connection node for a prefabricated modular steel structure trestle bridge. Background Technology

[0002] A trestle bridge is an elevated bridge structure. In recent years, with the continuous improvement of enterprise production capacity and the expansion of output and raw material demand, material transport trestle bridges have gradually developed into larger-scale structures. Trestle bridges have evolved through various structural forms to the steel structure trestle bridges we see today.

[0003] The first stage: brick-concrete structure trestle bridges, now completely obsolete; the second stage: reinforced concrete structure trestle bridges, with good overall integrity, but complex structure, heavy weight, complex construction, long project cycle, and excessively high total cost; the third stage: steel structure trestle bridges, currently widely used both domestically and internationally, in several forms including angle steel or other steel trusses, space frames, and steel pipe trusses; the fourth stage: prefabricated modular steel structure trestle bridges, a new type of material conveying trestle bridge. The prefabricated trestle bridge uses a steel structure support, and the trestle body is composed of several box units connected by high-strength bolts, assembled on-site to form a conveying corridor. A belt conveyor is then laid in the conveying corridor to form a transportation system.

[0004] Traditional support frame connection methods are generally flange connections or angle steel splicing. The disadvantages of traditional flange connections are that they involve complex procedures, large material waste, and difficulty in adjusting member errors, resulting in low flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a support frame connection node for a prefabricated modular steel structure trestle, which solves the problems of the existing flange connection method.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a support frame connection node for a prefabricated modular steel structure trestle, including a double clamp plate, with a first connecting plate and a second connecting plate sandwiched inside the double clamp plate. The second connecting plate is installed on an H-shaped steel column or a steel pipe column, and the first connecting plate is installed on a crossbeam.

[0008] Optionally, the double clamping plate includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are locked together by high-strength bolts, and both the first connecting plate and the second connecting plate are provided with through holes for the high-strength bolts to pass through.

[0009] Optionally, multiple high-strength bolts are provided.

[0010] Optionally, the steel pipe column is provided with a reinforcing ring plate for reinforcing the second connecting plate.

[0011] Optionally, at least one reinforcing ring plate is provided.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1) The second connecting plate is reinforced by using a reinforcing ring plate, which improves the seismic performance of the joint. At the same time, the materials used in the device are environmentally friendly and easy to weld with the steel pipe column.

[0014] 2) The double-clamp plate facilitates the adjustment of the distance between the first and second connecting plates when connecting the first and second connecting plates, making it convenient for the installation of the crossbeam. Attached Figure Description
