Background

In order to ensure the safety of the construction of the underground structure and the surrounding environment of the foundation pit, the side wall of the foundation pit and the surrounding environment need to be supported, reinforced and protected. In deep foundation pit engineering of high-rise buildings and subway construction, most of the deep foundation pit engineering is excavated in cities, various structures such as traffic roads, built buildings or pipelines and the like usually exist around the foundation pit, and a steel structure inner support system is widely applied in order to ensure the safety of the surrounding environment of the foundation pit, save the construction period and save the cost.

In the prior art, the lattice structure of the steel support of the foundation pit usually adopts the batten plate to be connected with the bolt holes on the upper surface and the lower surface of the section steel, the batten plate can protrude out of the surface of the section steel support, the lower support beam of the steel support needs to be adjusted frequently to avoid the batten plate, the construction is inconvenient, and the construction period is easily delayed.

Disclosure of Invention

The invention aims to provide a lattice type assembly structure of a foundation pit steel support, which is characterized in that a connector is arranged on the side edge of profile steel, so that a connecting piece is prevented from protruding out of the upper surface and the lower surface, the construction of the steel support and a support is more convenient and quicker, and the construction period is more favorably improved.

The invention adopts the following technical scheme:

a lattice type assembly structure of a foundation pit steel support comprises a support member 1 and a connector 4; the connector 4 comprises profile steel 401 and end plates 402 arranged at two ends of the profile steel 401, the height of the profile steel 401 is not higher than that of the supporting member 1, the profile steel 401 transversely penetrates through the supporting member 1, and one end plate is fixed with the outer side of the supporting member 1 through bolts.

Preferably, the connecting head 4 is fixed with the connecting head bolt on the adjacent supporting component 1.

Preferably, the other end plate is fixedly connected to the connecting element 2 for lateral expansion.

Further, the connecting piece 2 is provided with a middle section steel and two side end plates.

Preferably, stiffening plates 403 are arranged inside the end plates 402.

Preferably, the connecting node 3 is further included, and the connecting node 3 is connected with the inner side surface of the supporting member 1 and is used for connecting the inclined rod.

The beneficial effects of the utility model reside in that:

1) the connecting head is arranged on the side edge of the profile steel, so that the connecting piece can be prevented from protruding out of the upper surface and the lower surface of the supporting component, the construction of the steel support and the support is more convenient and faster, and the construction period is more favorably prolonged.

2) The connector is the structural design of expansion formula, and both sides all have the end plate, but interconnect also can connect through the connecting piece, can match in a flexible way, and expansibility is strong, and degree of standardization is high.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

referring to fig. 1, 3, 5-10, a lattice type assembly structure for a foundation pit steel support comprises a support member 1 and a connector 4; connector 4 includes shaped steel 401 and is located the end plate 402 at shaped steel 401 both ends, shaped steel 401 is high not be higher than bracing member 1, and shaped steel 401 transversely passes bracing member 1, one of them end plate with bracing member 1's outside bolt fastening.

In this embodiment, referring to fig. 1, the other end plate of the connecting head 4 is fixedly connected to the connecting member 2 for lateral expansion.

In this embodiment, see fig. 5-7, the connector 2 has a central section steel and two side end plates.

In this embodiment, see fig. 3, stiffening plates 403 are provided inside the end plates 402.

In this embodiment, see fig. 1, further comprising a connection node 3, said connection node 3 being connected to the inner side of the support member 1 for connecting the diagonal rods.

This foundation ditch steel shotcrete lattice formula assembly structure can assemble into many lattice formula structures, and the connector is formed by shaped steel, end plate, the welding of stiffening plate, and both sides all have the end plate, but interconnect also can pass through the connecting piece and connect.
