Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, and specifically to a concrete pouring construction structure. Background Technology

[0002] Expansion reinforcement strips are a technical measure that involves pouring shrinkage-compensating concrete at the pre-designed post-cast strip locations in the structure, thereby reducing or eliminating post-cast strips and expansion joints, and extending the continuous casting length of the components.

[0003] Existing expansion joint reinforcement strips, as seen in patent application number CN201220339988.0, prevent cracking of expansive concrete by placing steel bars and wire mesh within the expansion joint, thereby improving waterproofing. However, gaps, cracks, and cavities inevitably exist between expansive and shrinkage concrete, and water seepage still occurs at these defective areas.

[0004] Therefore, improving the waterproofness of the expansion reinforcement strip is a technical problem that urgently needs to be solved. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem of improving the waterproofness of expansion reinforcement strips, this utility model provides a concrete pouring construction structure with a first waterproof layer 200 at the bottom, thereby improving the overall waterproofness of the concrete and avoiding leakage problems in the concrete structure.

[0027] It should be noted that the concrete pouring construction structure of this utility model is used for, but not limited to, concrete pouring. For ease of explanation, this utility model only uses the application of the concrete pouring construction structure to concrete pouring as an example. The principle of the concrete pouring construction structure applied to other types of equipment is essentially the same as that applied to concrete pouring, and will not be elaborated here.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of a concrete pouring construction structure in one embodiment of the present invention. The concrete pouring construction structure includes a concrete cushion layer 100, a first waterproof layer 200, a grouting pipe 300, and two shrinkage concrete modules 400. The first waterproof layer 200 is laid on the concrete cushion layer 100, and the shrinkage concrete modules 400 are laid on the first waterproof layer 200. There is a pouring gap between the two shrinkage concrete modules 400. The grouting pipe 300 extends into the pouring gap and is used to pour expansive concrete mortar into the pouring gap.

[0029] In this embodiment, the first waterproof layer 200 is laid on the concrete cushion layer 100, and two shrinkage concrete modules 400 are laid on the first waterproof layer 200, with a pouring gap maintained between the shrinkage concrete modules 400. Expansion concrete mortar is injected into the pouring gap through the grouting pipe 300, and a reinforcing strip is formed after the expansion concrete mortar solidifies. Because the above-mentioned concrete pouring construction structure has the first waterproof layer 200 set on the concrete cushion layer 100, the overall waterproofness of the concrete is improved, avoiding the problem of concrete structure leakage.

[0030] In some embodiments, the shrinkage concrete module 400 includes a reinforcing bar frame 410 and a wire mesh 420. The reinforcing bar frame 410 is placed on the first waterproof layer 200, and the wire mesh 420 surrounds the outer periphery of the reinforcing bar frame 410 to enclose the pouring space.

[0031] In this embodiment, the reinforcing steel frame 410 serves as the main supporting structure, and the wire mesh 420 surrounds the outer perimeter of the reinforcing steel frame 410, enclosing a pouring space. Shrinkage concrete mortar is poured into the pouring space, and the wire mesh 420 prevents the shrinkage concrete mortar from overflowing.

[0032] Any implementation of the steel reinforcement frame 410 that can provide support is feasible. In some embodiments, the steel reinforcement frame 410 includes a number of first steel bars 411 and a number of second steel bars 412. The number of first steel bars 411 are laid horizontally on the first waterproof layer 200, and the number of second steel bars 412 are arranged horizontally above the second steel bars 412.

[0033] Based on the above embodiments, in some embodiments, the concrete pouring construction structure further includes a waterstop strip 500, which is fixed to the wire mesh 420.

[0034] In this embodiment, the waterstop strip 500 is located on the outside of the shrinkage concrete module 400, which can prevent water leakage.

[0035] In some embodiments, the waterstop strip 500 is bound to the wire mesh 420 by steel wire.

[0036] In this embodiment, the waterstop strip 500 is fixed by binding. The waterstop strip 500 can be bent through the binding point so that the waterstop strip 500 can conform to the outline of the outer side of the wire mesh 420.

[0037] Based on the above embodiments, in some embodiments, the waterstop strip 500 is a water-swellable waterstop strip 500.

[0038] In this embodiment, since the waterstop strip 500 is a water-swellable waterstop strip 500, the expanded waterstop strip 500 can fully fill the gaps in the concrete and improve the waterproofness of the concrete.

[0039] In some embodiments, the grouting pipe 300 includes a first conduit 310 and a second conduit 320. The first conduit 310 passes through the pouring gap, and one end of the second conduit 320 is connected to the first conduit 310, while the other end protrudes out of the pouring gap.

[0040] In this embodiment, the expansive concrete mortar is injected through the second conduit 320 protruding from the pouring gap. The expansive concrete mortar will flow into the pouring gap through the first conduit 310 and fill the pouring gap.

[0041] In some embodiments, a gap is maintained between the first conduit 310 and the first waterproof layer 200.

[0042] In this embodiment, the space between the first conduit 310 and the first waterproof layer 200 is filled with expansive concrete mortar. The solidified expansive concrete mortar can protect the first waterproof layer 200 and prevent it from being damaged.

[0043] In some embodiments, the first conduit 310 is fixed to the wire mesh 420.

[0044] In this embodiment, by fixing the first conduit 310 to the wire mesh 420, the first conduit 310 can be suspended above the first waterproof layer 200.

[0045] In some embodiments, the concrete pouring construction structure further includes a second waterproof layer 600, which is located in the pouring gap and is laid on top of the first waterproof layer 200.

[0046] In this embodiment, the second waterproof layer 600 further improves the waterproofness of the location where the pouring gap is located.

[0047] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail below:

[0048] The first waterproof layer 200 is laid on the concrete foundation 100. A reinforcing steel frame 410 is placed on top of the first waterproof layer 200. A wire mesh 420 surrounds the outer perimeter of the reinforcing steel frame 410 to enclose the pouring space. Shrinkage concrete mortar is poured into this space to form shrinkage concrete modules 400. Pouring gaps are maintained between the shrinkage concrete modules 400. Expansion concrete mortar is injected into these gaps through grouting pipes 300. Once the expansion concrete mortar has solidified, it forms a reinforcing strip. Because the first waterproof layer 200 is installed on the concrete foundation 100, the overall waterproofness of the concrete is improved, preventing leakage problems in the concrete structure.
