TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a house construction joint efficient waterproof structure and a waterproof method thereof. BACKGROUND

[0002] In the process of house building structure construction, in order to complete the pouring of concrete in stages, a construction joint is usually set, which is an intermittent surface in the building structure controlled and set by human, often appearing in floor slabs, shear walls, foundation slabs and other parts, and plays a role in relieving the time span of concrete construction and the arrangement of construction organization. However, since the construction joint is often located in the structure pressure surface or water seepage channel, the quality of waterproof treatment directly affects the durability and use function of the building;

[0003] In the traditional technology, the waterproof treatment of the construction joint is usually carried out by using water stop belt, water stop steel plate or water-swelling material, and the waterproof member embedded in the structure is used to form a physical barrier to block the water permeation path. Especially in high water seepage risk areas such as basement, underground pipe gallery and foundation raft, the water stop belt type waterproof member has become an indispensable treatment method for construction joint waterproofing.

[0004] Since the water stop belt needs to be accurately positioned and fixed before pouring the first concrete, when the water stop belt is subjected to vibration, flow thrust or steel bar blockage during pouring the first concrete, the water stop belt is prone to displacement and deviation from the designed installation position. In addition, the water stop belt itself is prone to deformation, and under the action of flow thrust, the water stop belt is prone to deformation such as twisting and folding, which affects the waterproof effect. SUMMARY

[0005] The present application aims to overcome the defects of the prior art and provide a house construction joint efficient waterproof structure and a waterproof method thereof, which not only ensures the stability of the waterproof structure and avoids deviation, but also enhances the waterproof effect.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present application is a house construction joint efficient waterproof structure, comprising:

[0007] A strip-shaped base connected at the designed position of the construction joint and having a length equal to the designed length of the construction joint;

[0008] Two rigid baffles for blocking the first poured concrete, connected on opposite sides of the top of the strip-shaped base, and a pouring space for pouring the second poured concrete is formed between the two rigid baffles, and the top elevation of the rigid baffle is flush with the top design elevation of the first poured concrete;

[0011] The further improvement of the efficient waterproof structure of the house construction joint is that the strip-shaped base is connected with the existing steel bar, and the first clamping groove for clamping the corresponding existing steel bar is arranged at the bottom of the strip-shaped base in the length direction.

[0012] The further improvement of the efficient waterproof structure of the house construction joint is that the elastic sealing core comprises:

[0013] A rubber core layer with pressure expansion performance;

[0014] A buffer layer wrapped outside the rubber core layer for absorbing the vibration load of the pre-poured concrete to protect the rubber core layer;

[0015] An outer coating layer wrapped outside the buffer layer for strengthening the sealing performance with the post-poured concrete.

[0016] The further improvement of the efficient waterproof structure of the house construction joint is that the connecting piece comprises a plurality of inverted U-shaped reinforcing ribs, the plurality of inverted U-shaped reinforcing ribs are arranged in the length direction of the strip-shaped base at intervals, each inverted U-shaped reinforcing rib is arranged above the elastic sealing core and connected to the two rigid baffles at both ends, and the limiting plate is connected to the top of the plurality of inverted U-shaped reinforcing ribs.

[0017] The further improvement of the efficient waterproof structure of the house construction joint is that the two sides of the elastic sealing core relatively close to the two rigid baffles are in a wave shape, and each wave trough of the elastic sealing core is opposite to one inverted U-shaped reinforcing rib.

[0021] Step 3: pouring the pre-poured concrete on both sides of the strip-shaped base;

[0022] Step 4: pouring the post-cast concrete from the gap to the pouring space until the elastic sealing core is pressed to expand and fills the pouring space with the post-cast concrete.

[0023] Compared with the prior art, the advantages of the present application are that:

[0024] By setting the rubber core layer to cooperate with the post-cast concrete to fill the pouring space, the waterproof effect is improved. BRIEF DESCRIPTION OF DRAWINGS

[0030] The embodiments of the present application will be described below through specific concrete examples, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure of the present specification. The present application can also be implemented or applied through other different specific embodiments, and various modifications or changes can be made to the details in the present specification based on different viewpoints and applications without departing from the spirit of the present application.

[0031] The efficient waterproof structure of the house construction joint of the present application and the waterproof method thereof will be further described in detail below in combination with the drawings and specific embodiments.

[0032] Please refer to Figs. 1-3 As shown in the figure, the efficient waterproof structure of the house construction joint comprises:

[0033] The strip-shaped base 1 is connected at the designed position of the construction joint and has a length equal to the designed length of the construction joint;

[0034] Two rigid baffles 2 for blocking the pre-cast concrete 8 are respectively connected to opposite sides of the top of the strip-shaped base 1, and a pouring space for pouring the post-cast concrete is formed between the two rigid baffles 2, and the top of the rigid baffles 2 is flush with the top design elevation of the pre-cast concrete 8;

[0035] An elastic sealing core 6 is longitudinally arranged in the pouring space, and is used to expand under pressure to fill the pouring space with the post-cast concrete when the post-cast concrete is poured;

[0036] A limiting plate 7 for preventing the elastic sealing core 6 from expanding out of the pouring space is arranged above the elastic sealing core 6 and is connected to the two rigid baffles 2 by a connecting piece, and the limiting plate 7 is arranged in the horizontal direction and has a top elevation flush with the top elevation of the rigid baffles 2, and a gap is reserved between the limiting plate 7 and the two rigid baffles 2 for the post-cast concrete to be poured into the pouring space.

[0037] By arranging the rubber core layer 601 to cooperate with the post-cast concrete to fill the pouring space, the compactness of the pouring space is improved, and the waterproof effect is improved.

[0038] Since the elastic sealing core 6 expands in all directions when it expands, by arranging the limiting plate 7, the elastic sealing core 6 is prevented from expanding upwards out of the pouring space, and the compactness is improved by cooperating with the post-cast concrete.

[0039] Specifically, the size of the elastic sealing core 6 is smaller than the pouring space.

[0040] Preferably, the strip-shaped base 1 is clamped with the existing steel bars 3, and first clamping grooves 4 are arranged at the bottom of the strip-shaped base 1 along the length direction and are spaced apart for clamping the corresponding existing steel bars 3.

[0041] Specifically, second clamping grooves 5 are also longitudinally arranged at the bottom of the strip-shaped base 1 for clamping the corresponding existing steel bars 3, and the plurality of first clamping grooves 4 and the second clamping grooves 5 are perpendicular to each other and communicate with the second clamping grooves 5.

[0042] The plurality of existing steel bars 3 are arranged in a grid shape, and the cross-shaped clamping grooves formed by the plurality of first clamping grooves 4 and the second clamping grooves 5 ensure the connection stability of the strip-shaped base 1 and avoid displacement of the strip-shaped base 1.

[0043] Preferably, the elastic sealing core 6 comprises:

[0044] A rubber core layer 601 having a pressure expansion property;

[0045] A buffer layer 602 wrapped on the outer side of the rubber core layer 601 for absorbing the vibration load of the pre-cast concrete 8 to protect the rubber core layer 601;

[0046] An outer coating 603 is coated on the outside of the buffer layer 602 to enhance the sealing with the post-poured concrete.

[0047] Specifically, the buffer layer 602 is a thermoplastic elastomer.

[0048] During the construction of the pre-poured concrete 8, a vibrating rod is needed to be used for vibration. By setting the buffer layer 602, the vibration load generated by the vibrating rod is diluted, and the rubber core layer 601 is prevented from being broken by vibration, which affects the use.

[0049] Specifically, the buffer layer 602 is an alkali-resistant polyurethane or polymer modified asphalt.

[0050] By setting the outer coating 603, the adhesion and sealing durability with the post-poured concrete are improved, the connection effect of the elastic sealing core 6 and the post-poured concrete is strengthened, and the waterproof performance is improved.

[0051] Preferably, the connecting piece includes a plurality of inverted U-shaped reinforcing ribs, and the plurality of inverted U-shaped reinforcing ribs are arranged at intervals along the length direction of the strip-shaped base 1. Each inverted U-shaped reinforcing rib is arranged above the elastic sealing core 6 and connected to two rigid baffles 2 at both ends, respectively. The limiting plate 7 is connected to the top of the plurality of inverted U-shaped reinforcing ribs.

[0052] By setting the inverted U-shaped reinforcing rib, a connection basis is provided for the limiting plate 7, and the limiting plate 7 is anchored in the subsequent pouring of the post-poured concrete, thereby improving the overall strength.

[0053] Preferably, the two sides of the elastic sealing core 6 close to the two rigid baffles 2 are both wavy, and each wave valley of the elastic sealing core 6 is opposite to one inverted U-shaped reinforcing rib.

[0054] By setting the elastic sealing core 6 to be wavy, when the elastic sealing core 6 is expanded under pressure, the elastic sealing core 6 still maintains a wavy shape due to the blocking of the plurality of U-shaped reinforcing ribs, thereby improving the connection effect with the post-poured concrete, improving the compactness and waterproof effect.

[0055] An efficient waterproof method for a house construction joint, comprising the steps of:

[0056] Step 1: providing the efficient waterproof structure for the house construction joint described above;

[0057] Step 2: connecting the strip-shaped base 1 at the designed position of the construction joint, so that the top elevation of the two rigid baffles 2 is flush with the top design elevation of the pre-poured concrete 8;

[0058] Step 3: pouring the pre-poured concrete 8 on both sides of the strip-shaped base 1;

[0059] Step 4: placing post-cast concrete from the gap into the casting space until the elastic sealing core 6 is pressed to expand and fill the casting space with the post-cast concrete.
