Description

Technical Field

[0001] The present invention relates to the technical field of building waterproof construction, and particularly relates to a standardized prefabricated lattice column waterproof structure and a construction method thereof. Background Technique

[0002] At present, with the development of underground space, deep foundation pit construction has become a common construction situation in building construction. Deep foundation pits often require a horizontal support system, and lattice columns need to be set as vertical load-bearing members to support the horizontal support. With the construction of the main structure, the construction of the structural floor slab and floor slab interferes with the lattice column. Due to the function of the lattice column, it cannot be demolished. Therefore, the lattice column must pass through the structural floor slab or floor slab and exist until the foundation pit construction is completed and the backfill soil is completed before it can be demolished.

[0003] At the place where the lattice column passes through the structural floor slab, waterproof treatment is required. For example, the waterproof structure disclosed in CN211816381U uses a waterstop steel plate welded around and inside the lattice column. However, due to the very small gap between the four angle steels of the lattice column, it is very difficult for hands and welding equipment to pass through the gap of the lattice column for operation. There is also a waterproof structure of the lattice column disclosed in CN113653201A that plays a waterproof role, but the above structure still has problems such as large construction difficulty and poor waterproof effect, and cannot achieve rapid construction and effective waterproofing. The present invention provides a standardized prefabricated lattice column waterproof structure and a construction method to solve the above problems. Summary of the Invention

[0015] Preferably, the waterproof strip is an expansion waterstop strip, the internal waterproof plate and the external waterproof plate are waterproof steel plates, and adjacent external waterproof plates are welded together.

[0039] As Figure 1 、 2 shown in 3, 4, 5, a standardized prefabricated lattice column waterproof structure is provided on the lattice column and connected to the structural floor slab, including an inner waterproof structure 1 and an outer waterproof structure 2. The inner waterproof structure 1 is horizontally arranged inside the lattice column, and the outer waterproof structure 2 is horizontally arranged outside the lattice column, in the same plane as the inner waterproof structure 1. The outer waterproof structure 2 is located outside the inner waterproof structure 1 and is connected to the inner waterproof structure 1.

[0040] In the present invention, the inner waterproof structure 1 and the outer waterproof structure 2 are provided on the lattice column, and the joints between the inner waterproof structure 1 and the outer waterproof structure 2 and the lattice column are sealed by the way of contact and fitting of the waterproof strips, improving the waterproof effect; moreover, the flexible contact between the waterproof strips and the lattice column can increase the sealing effect and at the same time improve the installation efficiency of the inner waterproof structure 1 and the outer waterproof structure 2.

[0041] As Figure 6 、 7As shown in FIGS. 8, the internal waterproof structure 1 includes a support frame 11, an internal waterproof plate 12, and an internal waterproof strip 13. The support frame 11 is provided on the bottom surface of the internal waterproof plate 12 and is connected to the lattice column. The internal waterproof strip 13 is provided on the outer periphery of the internal waterproof plate 12. The internal waterproof strip 13 is in close contact with the inner wall of the lattice column and is connected to the external waterproof structure 2.

[0042] The function of the support frame 11 is to provide pre - support and fixation, and it has a certain supporting effect on both the internal waterproof structure 1 and the external waterproof structure 2, and is set according to needs during actual construction.

[0043] Preferably, the support frame 11 is of a V - shaped structure, and its bottom end is welded to the lacing plate or limb member of the lattice column according to different installation positions.

[0044] As Figure 9 、 10 、11 shown, further, the external waterproof structure 2 includes external waterproof units. Two external waterproof units are arranged oppositely to form a rectangular ring - shaped external waterproof structure 2. The external waterproof structure 2 surrounds the outer periphery of the lattice column and is connected to the internal waterproof structure 1. The external waterproof unit includes an external waterproof plate 21 and an external waterproof strip 22. The external waterproof plate 21 is provided on the outer periphery of the external waterproof strip 22. The external waterproof strip 22 is located on the outside of the lattice column, is in close connection with the outer wall of the lattice column, and is connected to the internal waterproof strip 13.

The waterproof strip 132 is provided in the installation groove 131. The installation grooves 131 of the internal waterproof strip 13 and the external waterproof strip 22 are arranged oppositely, and the waterproof strips 132 of the internal waterproof strip 13 and the external waterproof strip 22 are connected to each other.

[0046] As Figure 11 、 12 shown, further, the internal waterproof strip 13 is provided with a groove, and the external waterproof strip 22 is provided with a rib. The rib of the external waterproof strip 22 is clamped in the groove of the internal waterproof strip 13.

[0051] Further, the external dimension of the internal waterproof structure 1 is larger than the internal cavity dimension of the lattice column, and the inner diameter dimension of the external waterproof structure 2 is smaller than the outer peripheral dimension of the lattice column. Since both the internal water stop strip 13 and the external water stop strip 22 are flexible structures, they are extruded and deformed with the lattice column after installation, playing a role in fixing and enhancing the water stop.

[0052] Preferably, the waterproof strip 132 is an expansion water stop strip, the internal waterproof plate 12 and the external waterproof plate 21 are waterproof steel plates, and the adjacent external waterproof plates 21 are welded and connected.
