Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] see Figure 1-6 , Eight-shaped lattice truss steel support structure, composed of reinforced concrete crown / waist beam 1, secondary pouring structure 2, reinforced concrete corbel 3, diagonal bracing structure 4, end truss steel support 5, middle truss steel support 6 The reinforced concrete corbel 3 provides the installation plane and angle for the steel support, so that the force of the steel support is simple and clear, and the secondary pouring structure 2 has the function of adjustment and leveling, which can minimize the impact of the construction errors of the surrounding structures on the steel support.

[0030] see figure 1 , the diagonal brace structure 4 is composed of expanded nodes 401, diagonal braces 402, cross-web rods 403, lug plate connectors 404, and prestressing device 405. The number is expanded, the diagonal brace...

Abstract

The invention relates to a splayed lattice type truss steel supporting structure which comprises an end truss steel support and a pair of symmetrically-arranged inclined strut structures. The end truss steel support comprises at least two supporting units which are sequentially connected, each supporting unit comprises a pair of parallel main stress rods, a connector is arranged at the end of each main stress rod, a large lug plate is arranged on the outer side of each connector, and a pair of small lug plates which incline forwards and backwards and are used for being hinged to the cross-shaped diagonal web members are arranged on the inner side of each connector. The inclined strut structure comprises a pair of parallel inclined struts, and the upper ends of the inclined struts are provided with lug plate connecting pieces used for being hinged to the large lug plates. The end part of the truss adopts an inclined strut reinforcing structure, so that the bearing range of the truss is enlarged, the excavation space is enlarged, and the steel consumption is reduced.

Description

technical field [0001] The invention relates to a splayed lattice type truss steel support structure, which belongs to the technical field of building construction. Background technique [0002] In order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, it is necessary to adopt support, reinforcement and protection measures for the side wall of the foundation pit and the surrounding environment. Whether it is a deep foundation pit project for high-rise buildings or subway construction, since most of them are excavated in cities, there are usually various structures such as traffic arteries, existing buildings or pipelines around the foundation pit. Safety, time saving, and cost saving, the steel structure internal support system is widely used. [0003] In the prior art, the arrangement of steel supports is too dense, resulting in too small effective space for excavation, slow construction speed, and excess...
