[0029] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0030] The utility model proposes a post-cast strip water-stopping and sealing structure, which is used for the post-cast strip construction at foundation slabs, walls, beams and other locations. It can accurately fix the water-stop steel plate at a preset position without the need for welding, and is easy to install and disassemble, thereby improving construction efficiency. It only requires 1-2 workers to complete, saving labor costs. The sealing quality is good, and no repairs are required in the later stage. The dismantled fixing devices, fixings and connecting parts can be recycled, further reducing construction costs.

[0031] like Figure 1 、 Figure 2 As shown, in this embodiment, the post-casting strip water-stopping and blocking structure is used for the construction of the post-casting strip 60 of the wall; the utility model proposes a post-casting strip water-stopping and blocking structure comprising structural steel bars 20, water-stopping steel plates 70, fixing devices 30, reinforcement members 40 and connectors 50: wherein the structural steel bars 20 extend from the preset positions of the intended cast structures 10 on both sides of the post-casting strip 60 to the post-casting strip 60; the water-stopping steel plates 70 are parallel to the structural steel bars 20. Specifically, water-stopping is required at the junction of the post-casting strip 60 and the structures to be constructed on both sides thereof. The steel plate 70, the waterstop steel plate 70 in this embodiment is arranged along the height direction of the wall, half of its width direction is arranged at the corresponding position of the proposed cast structure 10, and the other half needs to extend to the position of the post-cast strip 60; the fixing devices 30 are respectively abutted against the two sides of the waterstop steel plate 70 in the thickness direction, and are aligned with the contour line of the proposed cast structure 10, and are clamped with the structural steel bars 20; the two ends of the reinforcement 40 are respectively connected to the fixing devices 30 on both sides of the same waterstop steel plate 70; the two ends of the connecting member 50 are respectively connected to the corresponding reinforcement 40 on both sides of the post-cast strip 60.

[0032] In this embodiment, the above-mentioned structural steel bars 20 are structural steel bars 20 arranged horizontally and from top to bottom in the wall. The waterstop steel plate 70 is preferably arranged in the middle of the wall thickness, and the structural steel bars 20 are preferably steel bars closer to the outer edge in the wall thickness direction.

[0033] Normally, the two sides of the waterstop steel plate 70 in the thickness direction are respectively the water-facing surface and the water-repellent surface. The fixing device 30 in the present application abuts against the water-facing surface and the water-repellent surface of the waterstop steel plate 70 respectively, and at the same time is aligned with the contour line of the structure to be cast 10, thereby fixing the waterstop steel plate 70 in a preset position; at the same time, the specifications of the fixing device 30 are designed according to the thickness of the wall and the position of the structural steel bar 20. Since the structural steel bar 20 has been tied and fixed in advance, the fixing device 30 is fixed by the structural steel bar 20, so that the waterstop steel plate 70 between the two fixing devices 30 is accurately positioned at its designed position; the fixing device 30 is tightly connected to the waterstop steel plate 70 In one body, the proposed cast-in-place structure 10 and the post-cast strip 60 are separated so that the two can be used as a blocking structure during the concrete pouring construction of the proposed cast-in-place structure 10 after being connected, thereby realizing the blocking of the proposed cast-in-place structure 10; the fixing devices 30 on both sides of the water-stop steel plate 70 are connected as one body by setting the reinforcement 40, and then the fixing devices 30 on both sides of the post-cast strip 60 are connected as one body through the connecting member 50, thereby improving the integrity of the water-stop and blocking structure, and the connecting member 50 pushes against the reinforcement 40 on both sides of the post-cast strip 60, so that the fixing device 30 is not easy to move and deform under the lateral pressure of concrete pouring, thereby ensuring the concrete appearance quality effect of the proposed cast-in-place structure 10.

[0034] Through the above technical solution, this application is cleverly designed based on the positional relationship between the waterstop steel plate 70 and the sealing structure, combining the fixation of the waterstop plate and the installation of the sealing structure, simplifying the construction process, and improving the quality of concrete pouring in the post-casting zone 60. At the same time, it is easy to install and disassemble, which is conducive to improving construction efficiency and reducing construction costs.

[0035] Furthermore, if Figure 3 、 Figure 4 As shown, the above-mentioned fixing device 30 includes a main board 31 and a folding plate 32 vertically connected to the main board 31. The main board 31 is aligned with the outline of the proposed cast structure 10 and is used to seal the proposed cast structure 10; the folding plate 32 is attached to the waterstop steel plate 70 and is used to fix the waterstop steel plate 70 at its preset position, while realizing seamless connection between the fixing device 30 and the waterstop steel plate 70, which is conducive to forming an overall sealing structure; by providing the folding plate 32, the contact area between the fixing device 30 and the waterstop steel plate 70 is increased, so that the folding plates 32 on both sides can better position the waterstop steel plate 70, and the waterstop steel plate 70 can be firmly fixed without the need for welding connection, etc., which reduces the installation difficulty of the waterstop steel plate 70 and avoids damage to the waterstop steel plate 70 caused by welding operations, thereby ensuring the waterstop effect of the waterstop steel plate 70.

[0036] Furthermore, the main plate 31 is provided with a plurality of slots 311 , through which the structural steel bars 20 pass and are fixed by means of clamps.

[0037] The position of the slot 311 is designed according to the position of the structural steel bar 20. Depending on the position of the structural steel bar 20, a hole form or other slot 311 form can be adopted. In a preferred embodiment, the structural steel bar 20 is a steel bar close to the edges on both sides in the thickness direction of the wall and is arranged from top to bottom from the height of the wall. The slot 311 is preferably a U-shaped slot and is located at the end of the main board 31 away from the folding plate 32 and is correspondingly distributed along the length direction of the main board 31. The opening of the U-shaped slot faces the edge of the main board 31. During installation, the structural steel bar 20 can be passed through the slot 311 by fitting the folding plate 32 to the waterstop steel plate 70, making installation more convenient. The shape of the fixture matches the slot 311. As long as the slot 311 can be closed, its specific structure is not limited here.

[0038] Furthermore, a reinforcement plate 33 is vertically provided on one side of the main board 31 facing the post-cast strip 60, and a reserved hole 331 is provided on the end of the reinforcement plate 33 away from the main board 31. The reinforcement member 40 is passed through the reserved hole 331, connecting the reinforcement plates 33 on both sides of the waterstop steel plate 70 into one, and then connecting the fixing devices 30 on both sides of the waterstop steel plate 70 into one.

[0039] Specifically, the reinforcing plate 33 has a sufficient length, which is greater than half the width of the waterstop steel plate 70 , so that the reinforcing member 40 can cross the waterstop steel plate 70 and connect the reinforcing plates 33 on both sides thereof together.

[0040] Furthermore, a number of reinforcement plates 33 are evenly arranged along the length direction of the main board 31. At this time, the relatively outer edges of the two main boards 31 located on both sides of the waterstop steel plate 70 are fixed by structural steel bars 20, and the two main boards 31 are connected and fixed by a number of reinforcements 40. At the same time, the two main boards 31 clamp the waterstop steel plate 70, thereby achieving a more stable connection and fixation of the two fixing devices 30 and the waterstop steel plate 70.

[0041] Furthermore, the reinforcing plate 33 is arranged between the water-stop steel plate 70 and the structural steel bar 20, and the three are distributed along the width of the main board 31, so that each part of the main board 31 is evenly stressed, which is beneficial to improving the stability of the overall connection structure.

[0042] Preferably, a reinforcing plate 34 is further provided between the reinforcing plate 33 and the main board 31; by providing the reinforcing plate 34, the strength of the main board 31 can be improved, and the reinforcing plate 33 can be avoided from being directly welded to the main board 31, which causes the strength of the connection part of the main board 31 to be reduced, forming a weak link that affects the blocking effect.

[0043] In one specific embodiment, the reinforcement 40 is arranged along the width of the main plate 31, and the connector 50 is perpendicular to the reinforcement 40. To achieve a stable connection between the two, it is connected to the reinforcement 40 via an adapter 51. Preferably, the fixing devices 30 on both sides of the rear foot strap are symmetrically arranged, that is, the reinforcements 40 on both sides of the post-cast strip 60 are also symmetrically arranged. Each reinforcement 40 is connected to another reinforcement 40 on the other side of the post-cast strip 60 via an adapter 51. When the connector 50 is installed, it is pressed against the two reinforcements 40 on both sides, so that the fixing device 30 is adequately supported by the connector 50 under the lateral pressure of the concrete and will not easily deform or move.

[0044] Preferably, the adapter 51 adopts a fastener commonly used in construction, and its specific structure is the existing technology and will not be described in detail here; a number of connecting parts 50 are evenly arranged between the corresponding two reinforcement parts 40, and the connection part between the connecting part 50 and the reinforcement part 40 is preferably arranged between the two reinforcement plates 33 on the same side of the post-cast zone.

[0045] Furthermore, the reinforcement member 40 is fixed to the reinforcement plate 33 by fasteners. Specifically, threads are provided at both ends of the reinforcement member 40, and nuts are used as fasteners. When the two ends of the reinforcement member 40 pass through the reserved holes 331 of the reinforcement plate 33, nuts are provided on both sides of the reserved holes 331 to stably fix the reinforcement member 40 to the reinforcement plate 33. This method is more convenient for installation and removal, and is conducive to the turnover of the fixing device 30, the reinforcement member 40 and the connecting member 50.

[0046] The construction method of the post-casting strip water-stopping and blocking structure comprises the following steps:

[0047] Tie the structural steel bars 20 on one side of the post-cast strip 60 so that they extend into the post-cast strip 60;

[0048] Install a fixing device 30 at a preset position, pass the structural steel bar 20 through the slot 311 of the fixing device 30 on the structure 10 to be cast, and install a fixture to close the slot 311;

[0049] Temporarily fix the water-stop steel plate 70 so that the water-stop steel plate 70 fits on the folding plate 32 of the fixing device 30 , while ensuring that the water-stop steel plate 70 is in a preset installation position;

[0050] Install another fixing device 30 on the other side of the waterstop steel plate 70, and connect the structural reinforcement 20 on the other side to the fixing device 30, and fix them with a clamp; check to ensure that the waterstop plate and the fixing devices 30 on both sides are tightly fitted and firmly connected.

[0051] Install the reinforcement member 40 to connect the fixing devices 30 on both sides of the water-stop steel plate 70 into one piece; specifically, pass the reinforcement member 40 through the reserved holes 331 of the corresponding two reinforcement plates 33 and fix the reinforcement member 40 to the reinforcement plates 33 with bolts;

[0052] Repeat the above steps to complete the tying of the structural steel bars 20 on the other side of the post-casting strip 60, the installation of the water-stop steel plate 70 and the installation of the fixing device 30;

[0053] Install the connecting piece 50 to connect the corresponding reinforcement pieces 40 on both sides of the post-cast strip 60 into one body; specifically, use the adapter 51 for connection and fixation, and the corresponding two reinforcement pieces 40 are connected by two connecting pieces 50. The two connecting pieces 50 are respectively arranged near the connection part between the reinforcement piece 40 and the reinforcement plate 33, and are located between the two reinforcement plates 33 on the same side.

[0054] Pour the concrete of the proposed structure 10 on both sides of the post-casting strip 60; specifically, the formwork of the proposed structure 10 has been completed before the concrete is poured, and ensure that the formwork is tightly fitted with the fixing device 30 in this application to prevent leakage during the pouring process.

[0055] The connector 50, the reinforcement 40 and the fixing device 30 are removed in sequence; specifically, after the concrete strength reaches the requirement, the connector 50, the reinforcement 40 and the fixing device 30 in this application can be removed and transferred to the next post-casting zone 60 for use.

[0056] This application is cleverly designed based on the positional relationship between the waterstop steel plate and the sealing structure, combining the fixation of the waterstop plate and the installation of the sealing structure, simplifying the construction process and facilitating installation and disassembly. It only requires 1-2 workers to complete, which is beneficial to improving construction efficiency; a fixing device is tightly connected with the waterstop steel plate to form a sealing structure, which has good integrity and stability, does not require welding operations, and improves the quality of concrete pouring in the post-pouring zone; the fixing devices, reinforcements and connectors in this application can all be used in rotation, which is beneficial to reducing construction costs.

[0057] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
