Problems solved by technology
[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an integrated connecting plate for preventing continuous collapse of cold-formed thin-walled steel joists, so as to solve the problems that may occur in cold-formed thin-walled steel buildings in the prior art. The cold-formed steel joists and their floors collapsed due to the failure of local load-bearing walls, and even the continuous collapse of the overall building structure; taking into account the existing technology, due to the use of cold-formed thin-walled steel joists. The problem of irregular plane layout of wall columns can improve the convenience of construction of this type of building structure

Embodiment
[0035] The integrated connecting plate of the present invention is as figure 2As shown, mass production can be carried out in the factory using steel stamping technology or welding technology. It is an integral structure formed by connecting the upper connecting end plate 7, the stiffening rib 9, the square gusset plate 6 and the lower connecting end plate 8 sequentially, wherein the upper connecting end plate 7 and the lower connecting end plate 8 are arranged horizontally and parallel to each other, and the stiffening rib 9 Arranged vertically with the square gusset plate 6 and perpendicular to each other, the square gusset plate 6 has screw holes 4-1 and bolt holes 5-1. There are bolt holes 5-1 on the upper connecting end plate 7, and screw holes 4-1 on the lower connecting end plate 8.
[0036] When used, such as image 3 As shown, at the construction site, first align two adjacent C-shaped cold-formed thin-walled steel joists 1 at the same height and on the same buildi...

The invention discloses a continuous collapse-proof cold-formed thin-walled steel joist integrated connecting plate, a connecting structure and a construction method thereof. , The lower connection end plate perpendicular to the plane position of the square gusset plate and the upper connection end plate with stiffeners. The connection structure is to connect the connecting plate and the cold-formed thin-walled steel joist through high-strength bolts and self-tapping screws, connect with the upper floor of the joist through L-shaped bolts or pressure plate bolts, and connect with the lower wall of the joist. The corresponding upper rails are connected by self-tapping screws. The invention makes the plane layout of the load-bearing wall column of the building structure regular, improves the reliability and construction convenience of the cold-formed thin-walled steel building, and solves the problem of local load-bearing that may occur in the existing cold-formed thin-walled steel building Continuous collapse of cold-formed thin-walled steel joists and their floors caused by wall failure.
Description
technical field [0001] The invention relates to an integrated connection plate, a connection structure and a construction method of a cold-formed thin-walled steel joist for preventing continuous collapse, and belongs to the technical field of civil engineering. Background technique [0002] Compared with the traditional reinforced concrete structure, the steel structure has the characteristics of green environmental protection, good seismic performance, fast construction speed, and recyclable materials. With the rapid development of the national economy, my country's steel output has leapt to the first place in the world, and the domestic steel structure industry has also developed rapidly. However, compared with developed countries, the proportion of steel structure buildings in my country's steel output is still significantly low. Significant gaps still exist. my country is in the stage of rapid industrialization and urbanization, the annual project construction volume i...
