Fabricated lattice type H-shaped bearing steel support

Abstract

The invention discloses a fabricated lattice type H-shaped bearing steel support. The fabricated lattice type H-shaped bearing steel support is formed by extension of a plurality of frames, and each frame comprises section steels, horizontal supports, diagonal supports and T-shaped connection plates. The section steels are connected with the T-shaped connection plates by bolting, and the horizontal supports and the diagonal supports form a skeleton of each frame with the section steels through the T-shaped connection plates and bolts. The plurality of frames are connected through the T-shaped connection plates, the horizontal supports and the diagonal supports, and the section steels, in the vertical height direction, of different frames are connected through the connection plates and the bolts. The fabricated lattice type H-shaped bearing steel support is simple in structural style and efficient and convenient to fabricate.

Description

technical field [0001] The invention relates to a building construction support, in particular to an assembled lattice structure load-bearing H-shaped steel support. Background technique [0002] Setting up formwork supports during the construction of cast-in-place reinforced concrete structures and setting up independent supports or operating platforms during the installation of steel structures is an indispensable work content in construction; this work is an extremely important link in construction. Only when various supports, The cast-in-place work of the reinforced concrete structure and the installation of the steel structure can only be completed on the support or operation platform. The quality of the support, support or operation platform will directly affect the construction quality, safety, construction period and cost. Therefore, from the construction unit to the construction unit, great attention is paid to the erection of supports, supports or platforms. There...

Problems solved by technology

[0003] ① The axis of the rod is seriously eccentric

[0004] ②Low safety of force transmission

The internal force of the rod is transmitted by the friction between the fastener and the rod. The magnitude of the friction is related to the tightening force of the fastener and the friction coefficient between the contact surfaces, which determines that the friction has a great influence. Randomness, low safety of force transmission method;

[0005] ③Verticality is difficult to guarantee

The standard cross-sectional size of scaffold steel pipe is φ48×3.5, which is small and easy to bend, so it is difficult to ensure the verticality of the bracket;

[0006] ④ Large volume of installation, disassembly and transportation

[0008] ① There is no systematic consideration, so most of the brackets are consumed at one time, and the cost of use is high;

[0009] ② Each application needs to be specially designed and produced, the application is complicated, and the technical level of the users is very high, so it is difficult to promote
