Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a post-cast strip closing structure. Background Art
[0002] The post-cast joint is used during construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. After the concrete on both sides solidifies, the post-cast joint is filled inside to connect the entire structure into a whole.
[0003] However, in actual operation, since the concrete on both sides of the two post-casting joints is cast and the concrete solidification time is relatively long, during the solidification process of the concrete on both sides, the concrete may flow into the post-casting joints and the liquid inside the concrete may flow into the post-casting joints, resulting in low quality at the subsequent post-casting joints and lack of content in the concrete on both sides. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a post-casting belt closing structure.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A post-cast strip enclosed structure, comprising:
[0007] Two concrete blocks, wherein the post-cast strip body is formed between the two concrete blocks;
[0008] The closing mechanism comprises a placing plate, a through slot is provided at the lower end of the placing plate, a plurality of sliding rods are fixedly connected to the inner wall of the through slot, and the side walls of the plurality of sliding rods are slidably connected to two closing plates, and the side walls of the two closing plates which are far from each other are respectively fitted with the inner walls of the two sides of the post-casting belt body, and the inner wall of the through slot is rotatably connected with a bidirectional lead screw, and the side walls of the bidirectional lead screw are threadedly connected with the side walls of the two closing plates, and the closing plate is L-shaped;
[0009] A connecting mechanism is used for connecting four closing plates on two placement plates.
[0010] Preferably, the connecting mechanism includes two clamping plates, and the two clamping plates are respectively located on the side walls on the same side of two closing plates. The side walls of the closing plates away from the clamping plates are provided with clamping grooves, and the clamping grooves cooperate with the clamping plates, and the clamping plates are connected to the closing plates corresponding to the clamping grooves by multiple first bolts.
[0011] Preferably, raised plates are mounted on the upper ends of two adjacent placement plates via a plurality of second bolts.
[0012] Preferably, one end of the bidirectional lead screw passes through the side wall of the placement plate and is fixedly connected to a handwheel, a side wall of the bidirectional lead screw outside the placement plate is provided with a thread, and a nut is connected to the threaded side wall.
[0013] The utility model has the following beneficial effects:
[0014] 1. By setting up a closing mechanism, the side walls of the two closing plates that are away from each other are respectively fitted with the side walls of the two concrete blocks. This effectively prevents the concrete from flowing into the post-casting strip and the liquid inside the concrete from flowing into the post-casting strip during the solidification process of the two concrete blocks, resulting in low quality at the subsequent post-casting strip and lack of content in the concrete on both sides.
[0015] 2. By setting a connecting mechanism, the card plate on the closing plate is inserted into the card groove on the closing plate close to it, thereby completing the airtight connection between the two closing mechanisms, increasing the sealing effect on the post-casting strip body, and can be used in post-casting strip bodies of different lengths.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-4 A post-cast strip closed structure includes two concrete blocks 1, and a post-cast strip body 2 is formed between the two concrete blocks 1.
[0023] The closing mechanism includes a placing plate 3, a through groove 4 is opened at the lower end of the placing plate 3, a plurality of sliding rods 5 are fixedly connected to the inner wall of the through groove 4, and the side walls of the plurality of sliding rods 5 are slidably connected to two closing plates 6 together, and the side walls of the two closing plates 6 that are away from each other are respectively fitted with the inner walls on both sides of the post-casting strip body 2, and the inner wall of the through groove 4 is rotatably connected with a bidirectional screw 7, and the side walls of the bidirectional screw 7 are threadedly connected to the side walls of the two closing plates 6, and the closing plate 6 is L-shaped.
[0024] Further, such as Figure 1 As shown, the side walls of the two closing plates 6 that are away from each other are respectively fitted with the side walls of the two concrete blocks 1. This effectively prevents the concrete from flowing into the post-casting strip and the liquid inside the concrete from flowing into the post-casting strip during the solidification process of the two concrete blocks 1, resulting in low quality at the subsequent post-casting strip and lack of content in the concrete on both sides.
[0025] One end of the bidirectional lead screw 7 passes through the side wall of the placement plate 3 and is fixedly connected to a handwheel 8. The side wall of the bidirectional lead screw 7 outside the placement plate 3 is provided with a thread, and the threaded side wall is connected to a nut 9. Furthermore, the side wall of the nut 9 fits tightly with the side wall of the placement plate 3 to ensure the sealing stability of the two closing plates 6 within the post-casting strip body 2.
[0026] The connecting mechanism is used for connecting the four closed plates 6 on the two placement plates 3. The connecting mechanism includes two clamping plates 11. The two clamping plates 11 are respectively located on the side walls of the same side of the two closed plates 6. A clamping groove 10 is provided on the side wall of the closed plate 6 away from the clamping plate 11. The clamping groove 10 cooperates with the clamping plate 11. The clamping plate 11 is connected to the closed plate 6 corresponding to the clamping groove 10 through a plurality of first bolts 12.
[0027] Further, such as Figure 2 and 3 As shown, the card plate 11 on the closing plate 6 is inserted into the card groove 10 on the closing plate 6 close to it, thereby completing the airtight connection between the two closing mechanisms, increasing the sealing effect inside the post-cast strip body 2, and can be used in post-cast strip bodies 2 of different lengths.
[0028] The upper ends of two adjacent placement plates 3 are installed with raised plates 14 through a plurality of second bolts 13 , so as to seal the upper ends of the two placement plates 3 and prevent foreign matter from falling into the post-casting strip body 2 .
[0029] During the construction process, after the two concrete blocks 1 are poured, a post-casting strip body 2 is formed between the two concrete blocks 1, and then the placement plate 3 is placed on the two concrete blocks 1, so that the two closing plates 6 are located in the post-casting strip body 2, and then the hand wheel 8 is rotated clockwise to make the bidirectional screw 7 rotate clockwise, thereby driving the two closing plates 6 away from each other, and then the side walls of the two closing plates 6 that are away from each other are respectively attached to the side walls of the two concrete blocks 1. This effectively prevents the concrete from flowing into the post-casting strip and the liquid inside the concrete from flowing into the post-casting strip during the solidification process of the two concrete blocks 1, resulting in low quality at the location of the subsequent post-casting strip, and the concrete on both sides will also have a lack of content.
[0030] After the positions of the two closing plates 6 are determined, the side wall of the rotating nut 9 is closely fitted with the side wall of the placement plate 3 to ensure the sealing stability of the two closing plates 6 within the post-casting strip body 2;
[0031] At the same time, when multiple closing mechanisms need to be connected, the two card plates 11 and the two card slots 10 on the four closing plates 6 that are close to each other are matched one by one, and then the connection between the four closing plates 6 is completed through multiple first bolts 12, and the raised plates 14 are installed at the upper ends of the two placement plates 3 through multiple second bolts 13 to seal the two placement plates 3 and prevent external impurities from falling into the post-casting strip body 2.
[0032] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
