Description

Technical Field

[0001] The utility model relates to the field of waterproof coiled materials, in particular to a waterproof concrete prefabricated assembly and a combined assembly. Background Art

[0002] Prefabricated assembled structures are prefabricated in factories and assembled in a standardized manner on site, which not only achieves a modular assembly effect, but also has a short construction period and overall stability. The waterproofing of traditional prefabricated spliced ​​concrete structures mainly relies on the self-waterproofing of structural concrete and the extrusion of sealing pads at the joints, or the use of flexible waterproof materials to be set on the water-facing surface of the assembled structure.

[0003] However, prefabricated assembly is mainly based on reinforced concrete structure, and concrete structure has the characteristics of looseness, cracking and dynamic cracks. Once cracks appear in the concrete structure, it will cause water leakage. With the passage of time, under the conditions of internal stress and various loads and external forces, the concrete cracks will gradually expand and the degree of water leakage will be further aggravated. Moreover, it is difficult to ensure that the prefabricated concrete structure does not produce prestressed cracks during the production, transportation and installation of prefabricated concrete parts. In addition, the long-term structural vibration after the road is opened to traffic will cause cracks of varying degrees in the prefabricated concrete components, thereby creating leakage risks.

[0004] Traditional pre-laid anti-adhesive waterproof membranes include asphalt-based, polymer, and rubber-based. Pre-laid anti-adhesive waterproof membranes are constructed in an empty layer. After the concrete is poured, the pre-laid anti-adhesive waterproof membranes are fully bonded to the concrete under the dual physical and chemical effects of the concrete, thus forming a structural full-adhesive waterproof membrane.

[0005] Therefore, it is a technical problem to be solved urgently to provide a kind of waterproof concrete prefabricated assembly and assembly in the field of waterproof membrane in a targeted manner. Utility Model Content

[0006] The utility model aims to provide a waterproof concrete prefabricated assembly and assembly, which can achieve waterproof effect by anchoring the concrete assembly and the flexible waterproof layer.

[0007] To achieve the above-mentioned purpose, the solution of the utility model is to provide a waterproof prefabricated concrete assembly, including: a concrete assembly and a flexible waterproof layer, wherein the flexible waterproof layer is anchored in the outer surface of the concrete assembly.

[0008] Furthermore, the flexible waterproof layer includes but is not limited to one of a reverse-adhesive waterproof membrane, a special-shaped anchor waterproof board and a backing geotextile waterproof membrane.

[0009] Furthermore, the anchoring and embedding combination between the concrete assembly and the flexible waterproof layer requires pre-laying of the flexible waterproof layer on the bottom form of the concrete assembly, followed by tying steel bars and pouring to obtain the concrete assembly.

[0010] A waterproof concrete assembly comprises a plurality of prefabricated waterproof concrete assembling pieces, wherein the prefabricated waterproof concrete assembling pieces are stacked and assembled in sequence in a vertical direction.

[0011] Furthermore, the adjacent waterproof concrete prefabricated assemblies are sealed with glue at the joints.

[0012] Furthermore, adjacent prefabricated waterproof concrete assemblies are provided with single-sided self-adhesive tape edge sealing at one side of the joint close to the flexible waterproof layer.

[0013] Furthermore, a bottom plate waterproof layer and a cushion layer are sequentially arranged below the waterproof concrete prefabricated assembly.

[0014] Advantages of this utility model:

[0015] 1. Solve the drawbacks of traditional prefabricated concrete components that only rely on structural self-waterproofing + water-stopping measures at the joints. This drawback involves concrete structural cracks of prefabricated components, improper maintenance, and structural joint waterproofing problems caused during storage, transportation, and assembly. By integrating the flexible waterproof layer with prefabricated concrete as a whole, waterproofing defects caused by the above structural cracks can be avoided.

[0016] 2. The prefabricated assembled concrete components are integrated with the flexible waterproof layer, which not only achieves the combination of rigid and flexible waterproofing, but also saves construction time and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] Example 1

[0022] A waterproof prefabricated concrete assembly, comprising: a concrete assembly 1 and a flexible waterproof layer 2, wherein the flexible waterproof layer 2 is anchored on the outer surface of the concrete assembly 1;

[0023] The flexible waterproof layer 2 is a reverse-adhesive waterproof membrane; the anchoring connection between the concrete assembly 1 and the flexible waterproof layer 2 requires pre-laying the flexible waterproof layer 2 on the bottom mold 3 of the concrete assembly 1, and then tying steel bars and pouring to obtain the concrete assembly 1.

[0024] Example 2

[0025] A waterproof concrete assembly comprises three prefabricated waterproof concrete assemblies, wherein the prefabricated waterproof concrete assemblies are stacked and assembled in sequence in a vertical direction.

[0026] The adjacent prefabricated waterproof concrete assemblies are sealed with glue at the joints; the adjacent prefabricated waterproof concrete assemblies are provided with a single-sided self-adhesive tape 4 for edge sealing at the side of the joints close to the flexible waterproof layer 2; and a bottom plate waterproof layer 5 and a cushion layer 6 are provided in sequence under the bottommost prefabricated waterproof concrete assemblies.

[0027] By pre-setting the composite waterproof membrane with physical anchoring effect on the concrete slurry on the bottom mold 3 of the prefabricated assembled concrete component, the factory-prefabricated concrete assembly component and the flexible waterproof layer 2 can be produced simultaneously, which not only ensures the structural self-waterproofing + flexible full-adhesive waterproofing effect, but also saves the construction period of the subsequent waterproofing layer. Therefore, while ensuring the waterproofing effect of the prefabricated assembled building, the construction speed of the prefabricated assembled building is improved.
