Description

Technical Field

[0001] The utility model belongs to the technical field of basement structures, and in particular relates to an integrally cast cushion structure for a basement. Background Art

[0002] The significant difference in gravity load between a high-rise building and its connected multi-story podium causes uneven foundation settlement. Severe uneven settlement can damage structural components at the connection between the high-rise and the podium. To mitigate the impact of uneven settlement on the structure, a certain width is often reserved within the podium structural components adjacent to the high-rise during construction. Once the structures on both sides are completed and settlement has stabilized, concrete is poured in the reserved area to connect the structures. This reserved width is called a post-construction strip.

[0003] Before the post-casting strip is integrally poured, a cushion structure needs to be constructed in the post-casting strip. The existing cushion structure has a poor waterproof effect and is prone to groundwater leakage. Utility Model Content

[0004] The purpose of the utility model is to provide a basement integrally cast cushion structure to solve the problems raised in the above background technology.

[0006] As a preferred embodiment, the interior of the anti-seepage concrete layer is paved with glass fiber mesh cloth.

[0007] As a preferred embodiment, the upper surface of the first waterproof membrane layer is coated with a polymer modified asphalt waterproof coating layer.

[0008] As a preferred embodiment, the lower surface of the second waterproof membrane layer is coated with a polyurethane waterproof coating.

[0009] As a preferred embodiment, the first waterproof membrane layer and the second waterproof membrane layer are both formed by paving SBS waterproof membrane.

[0010] As a preferred embodiment, a plurality of reinforcing rods are inserted into the upper surface of the waterstop steel plate, and the reinforcing rods extend into the bottom wall of the post-cast zone.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The integrally cast cushion structure of the basement can improve the waterproof effect of the cushion structure by setting a waterstop, an anti-seepage concrete layer, a first waterproof coiled material layer, a waterstop steel plate, a second waterproof coiled material layer and an asphalt waterproof grease layer, play a role in blocking and preventing groundwater from seepage, and avoid groundwater leakage;

[0013] The basement is an integrally cast cushion structure, and the setting of polymer modified asphalt waterproof coating layer and polyurethane waterproof coating can further improve the waterproof and anti-seepage effect of the cushion structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0020] See also Figure 1-3The utility model provides a basement integral pouring cushion structure, including a water stop 1 laid in a post-casting strip, a water stop 1 is laid on the top of the water stop 1, a first waterproofing membrane layer 3 is laid on the top of the water stop concrete layer 2, a water stop steel plate 4 is laid on the top of the first waterproofing membrane layer 3, and a second waterproofing membrane layer 5 is laid on the top of the water stop steel plate 4. The first waterproofing membrane layer 3 and the second waterproofing membrane layer 5 are both made of SBS waterproofing membrane, which is impregnated and coated with asphalt with styrene-butadiene-styrene thermoplastic elastomer as a modifier. The material is a rollable sheet waterproofing membrane made of insulating materials such as polyethylene film, fine sand, mineral materials, or aluminum foil or copper foil. The upper surface is covered with a layer of asphalt waterproofing grease 6 between the waterstop steel plate 4 and the second waterproofing membrane layer 5. Asphalt waterproofing grease refers to a plastic or elastoplastic sealing material made from petroleum asphalt as a base material, with the addition of softeners, film-forming agents, fillers, and modifying materials. Softeners include heavy turpentine, pine tar, motor oil, and heavy diesel; film-forming agents include fish oil, castor oil, and tung oil; fillers include talc; and modifying materials include rubber and resin. The arrangement of the waterstop 1, the impermeable concrete layer 2, the first waterproofing membrane layer 3, the waterstop steel plate 4, the second waterproofing membrane layer 5, and the asphalt waterproofing grease layer 6 can improve the waterproofing effect of the cushion structure, block groundwater, and prevent groundwater leakage.

[0021] The interior of the impermeable concrete layer 2 is covered with a glass fiber mesh 21. The glass fiber mesh is based on a glass fiber woven fabric and is coated with a polymer anti-emulsion. This provides excellent alkali resistance, flexibility, and high tensile strength in both the warp and weft directions. The provision of the glass fiber mesh 21 enhances the structural strength of the impermeable concrete layer 2.

[0022] Among them, the upper surface of the first waterproof membrane layer 3 is coated with a polymer modified asphalt waterproof coating layer 31, which is a water-emulsion or solvent-based waterproof coating prepared with asphalt as the base material and modified with synthetic high molecular polymers. The provision of the polymer modified asphalt waterproof coating layer 31 can further improve the waterproof and anti-seepage effect of the cushion structure.

[0023] Among them, the lower surface of the second waterproof roll material layer 5 is coated with a polyurethane waterproof coating 51. The polyurethane waterproof coating 51 is formed by evenly applying a polyurethane waterproof paint. The polyurethane waterproof paint has the characteristics of high strength, large elongation, and good water resistance. By setting the polyurethane waterproof coating 51, the waterproof and anti-seepage effect of the cushion structure can be further improved.

[0024] Among them, several reinforcement rods 41 are inserted into the upper surface of the waterstop steel plate 4, and the reinforcement rods 41 extend into the bottom wall of the post-cast strip. Through the setting of the reinforcement rods 41, the waterstop steel plate 4 and the following structure can be connected and reinforced, thereby improving the stability of the cushion structure.

[0025] The working principle and usage process of the present invention: First, by setting the waterstop strip 1, the anti-seepage concrete layer 2, the first waterproof roll material layer 3, the waterstop steel plate 4, the second waterproof roll material layer 5 and the asphalt waterproof paste layer 6, the waterproof effect of the cushion structure can be improved, and the groundwater can be blocked and prevented from seepage, which can avoid groundwater leakage. By setting the polymer modified asphalt waterproof coating layer 31 and the polyurethane waterproof coating layer 51, the waterproof and anti-seepage effect of the cushion structure can be further improved.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
