Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a waterproof structure where a lattice column passes through a bottom plate. Background Art

[0002] The typical approach to waterproofing the base plate where a lattice column penetrates the main structure is to install a ring of water-swelling rubber waterstop strips on the outside bottom of the lattice column, and then weld a waterstop steel plate around the outside of the lattice column. Both the water-swelling rubber waterstop strips and the waterstop steel plate only provide waterproof protection on the outside of the lattice column, while internal waterproofing of the lattice column has been largely overlooked. Furthermore, conventional external waterproofing measures, such as those used in soft soil or environments with low groundwater levels, cannot meet the requirements for preventing leakage at the lattice column penetration point. Utility Model Content

The waterstop strips are arranged in a circle along the circumferential direction of the lattice column. Two waterstop strips are provided on the lattice column, which are respectively located above and below the waterstop steel plate. The waterstop strips are arranged in the base plate.

[0008] Furthermore, it also includes a waterproof coating layer, which is applied to the inner side of the lattice column and the cushion layer at the outer wall of the lattice column.

[0009] Furthermore, sealing paste is filled between the inner annular hole of the through-laying layer and the outer wall of the lattice column.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Reference Figures 1 to 3 As shown, the utility model provides a waterproof structure where a lattice column passes through a bottom plate, comprising: a waterproof coil, a water-stop steel plate 2, and a water-stop strip 3.

[0021] Specifically, the waterproof roll material includes a through-laying layer 11 and an inner lining layer 12 .

[0022] In this embodiment, a base plate 7 is cast on a cushion layer 6. A lattice column 8 extends through the base plate 7 and cushion layer 6. The lattice column comprises four limbs 81 and a tie plate 82. The four limbs are arranged in a matrix. The tie plates connect two adjacent limbs. There are multiple tie plates, which are spaced apart along the length of the limbs.

[0023] Before pouring the bottom slab, the inner lining layer 12 is laid on the cushion layer 6 on the inner side of the lattice column 8. The shape and size of the inner lining layer are adapted to the shape and size of the inner cavity of the lattice column.

[0024] The through-layer 11 is laid on the cushion layer 6 on the outside of the lattice column 8. The through-layer 11 is formed with an inner ring hole. The inner ring hole is sleeved on the lattice column 8. A plurality of extension strips 111 are formed on one side of the inner ring hole of the through-layer 11. The extension strips 111 are laid on the inner lining layer 12 between two adjacent limbs 81 of the lattice column 8 and overlap on the other side of the inner ring hole of the through-layer 11. The corner of the inner ring hole of the through-layer 11 is turned up to form a first overturned layer. The first overturned layer is laid on the outer wall of the limb 81.

[0025] As a preferred embodiment, see Figure 1 As shown, the space between the inner annular hole of the through-lay layer 11 and the outer wall of the lattice column 8 is filled with sealing paste 5 .

[0026] See Figure 2 As shown, in this embodiment, the outer edge of the inner lining layer 12 is turned up to form a second turned-up layer 121. The second turned-up layer 121 is laid on the inner wall of the limb 81.

[0027] The water-stop steel plate 2 is embedded in the bottom plate 7. The outer side of the lattice column 8 and the inner side of the lattice column 8 are connected with the water-stop steel plate 2. The water-stop steel plate 2 is provided along the circumferential direction of the lattice column 8 in a circle.

[0028] Waterstop strips 3 are connected to the outside and inside of the lattice column 8. These strips 3 are arranged around the circumference of the lattice column 8. Two waterstop strips 3 are installed on the lattice column 8, one above and one below the waterstop steel plate 2. These strips 3 are installed within the base plate 7.

[0029] In this embodiment, the waterstop steel plate and a waterstop strip are arranged on the same layer of the gusset plate, and the other waterstop strip is arranged on the next layer of the gusset plate.

[0030] As a preferred embodiment, the waterstop strip 3 is a waterstop strip 3 that expands when exposed to water.

[0031] See Figure 1 As shown, the waterproof structure at the lattice column penetration base plate of the present invention further includes a waterproof coating layer 4. The waterproof coating layer 4 is applied to the inner side of the lattice column 8 and the cushion layer 6 on the outer wall of the lattice column 8. The waterproof coating layer 4 is a cement-based penetrating crystallization waterproof coating layer.

[0032] In this embodiment, the bottom of the base plate is a C20 early-strength concrete cushion layer, which ensures the molding quality of the cushion layer while providing a constructible working surface as early as possible.

[0033] A layer of cement-based penetrating crystallization waterproof coating is applied on all sides and on the inner and outer surfaces of the lattice column.

[0034] Then the waterproof membrane is constructed. First, a piece of waterproof membrane with the same internal size as the lattice column (i.e. the inner lining layer) is cut out and laid on the cushion layer inside the lattice column. Then the large surface waterproof membrane (through-laying layer) is laid.

[0035] When the waterproofing membrane is laid throughout the entire structure, it should be turned up at the angle steel of the lattice column with a height of 50mm. The middle area should be laid directly in a cross shape. The contact area between the waterproofing membrane and the lattice column should be sealed with sealing paste.

[0036] Water-expanding rubber waterstop strips are used to wrap around the inner and outer walls of the lattice column upwards, and waterstop steel plates are welded around the outer sides of the lattice column below the middle thickness of the base plate. Water-expanding waterstop strips are again set on the inner and outer walls of the lattice column above the waterstop steel plates to ensure the waterstop effect and avoid cracks caused by concrete pulling due to local settlement.

[0037] The waterproof structure of the utility model at the place where the lattice column passes through the bottom plate adopts a multi-layer, rigid-flexible waterproof approach to improve the waterproof effect of the place where the lattice column passes through the bottom plate, the process is simple, and the method has strong applicability.

[0038] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model.
