Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a lattice column which is free of cutting and easy to disassemble. Background Art

[0002] With the increasing development of urban rail transit construction, the foundation pits of urban subway stations are developing towards wider and deeper areas. The setting of lattice columns can divide large foundation pits into relatively small units, which is convenient for excavation and construction in stages, helps to control the deformation of the foundation pit and reduce the impact of construction on the surrounding environment.

[0003] Under traditional construction techniques, lattice columns are often cast together with the foundation pit structural slab, and then cut to remove them later. However, this method has many disadvantages. First, during the removal process, cutting tools are required, and the tight connection between the lattice columns and the foundation pit structural slab may cause damage to the structural slab. Second, using the cutting method to remove the lattice columns requires a long construction time, which may extend the entire project time. It also makes it difficult to ensure the aesthetics and structural stability.

[0004] Therefore, in order to solve the above problems, a lattice column which is easy to disassemble without cutting is proposed. Utility Model Content

The high-strength bolts pass through the connecting holes 5 on the support plate 1 3 and the support plate 2 4 and are threadedly connected to the nuts, which are used to fasten the support plate 1 3 and the support plate 2 4, thereby improving the stability of the connection and facilitating the disassembly of the standard section.

[0028] In this embodiment, the limiting support plates 7 include multiple ones, all of which are arranged in an L shape, and are arranged on the outside of the main limbs corresponding to the main limbs, connected to the main limbs by bolts, or welded to the main limbs, and the limiting support plates 7 are arranged in close contact with the main limbs to increase the contact area and thereby improve the supporting force; preferably, a rib plate is provided on the side of the limiting support plate 7 away from the main limbs, and the rib plate is connected to the support plate 1 3 and the support plate 2 4, so as to further improve the supporting force and stability of the limiting support plate 7.

[0029] In another embodiment, the auxiliary support assembly also includes a support hoop 9, which includes a left hoop and a right hoop. The left hoop and the right hoop are of the same size and are both set to be semicircular. The left hoop and the right hoop can be assembled into a full circle. A limiting groove 10 is provided on the inner side of the left hoop and the right hoop. The width of the limiting groove 10 is consistent with the overall thickness of the support plate 1 3 and the support plate 2 4.

[0030] Working principle: First, four main limbs and several gusset plates are welded into a standard section 1 of a certain length at the construction site, and the two ends of the standard section 1 are respectively connected to the support plate 1 3 and the support plate 2 4, and the limit support plates 7 are welded on the support plate 1 3 and the support plate 2 4. After the outer side of the standard section 1 is calibrated and aligned with the limit support plates 7, the main limbs of the standard section 1 are connected or welded by bolts to form the standard section 1 as a whole; then the support plate 1 3 and the support plate 2 4 of the adjacent standard sections 1 are aligned so that the connection holes 5 correspond, and then high-strength bolts are passed through the connection holes 5 and connected with nuts to preliminarily connect the support plate 1 3 and the support plate 2 4; then the support hoop 9 is opened, and the limit groove 10 of the support hoop 9 is clamped on the outer side of the support plate 1 3 and the support plate 2 4, and then the left hoop and the right hoop are connected as a whole through the connecting piece 12, which improves the stability of the connection between the support plate 1 3 and the support plate 2 4; the structural plate 2 is supported by formwork, and a cavity of sufficient size is reserved at the position of the structural plate 2 corresponding to the lattice column, such as Figure 3 When pouring the top plate, the steel bars in the top plate are passed through the lattice holes, and the standard section 1 of the lattice column is poured normally. A structural reserved groove 8 is reserved on the lower surface where it intersects with the lattice column. The structural reserved groove 8 is used to accommodate the support plate 1 3 and the support plate 2 4, and ensure that it can be normally connected to the lattice column below through the connection component 6; after the underground structure construction is completed, the demolition work is carried out. First, the support hoop 9 is removed, and then the high-strength bolts on the support plate 1 3 and the support plate 2 4 are removed. After the lattice column is hoisted and removed, the structural reserved groove 8 at the structural plate 2 is re-cast to become one with the concrete structural plate 2.
