Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of post-cast strips, in particular to a post-cast strip closing cover plate. Background Art
[0002] In order to prevent the entry of debris and sewage into the post-casting strip before filling, it is necessary to take closing measures, and the existing closing measures usually use a closed cover plate to block it. In the prior art, a revolvable post-casting strip closing cover plate disclosed in Chinese patent CN219281333U, a post-casting strip closing device for shear walls in underground engineering disclosed in CN218375197U, a revolvable closing cover plate for post-casting strip disclosed in CN217679286U, and a prefabricated board closing device for shear wall post-casting strip disclosed in CN209989847U, etc., are mainly to prevent rainwater or surrounding debris from falling into the steel mesh in the post-casting strip, but they all ignore the water intruding from the concrete surface on both sides. This water will enter the steel mesh of the post-casting strip along the side walls on both sides of the post-casting strip, or stay in the water-stopping steel plate, which will seriously affect the waterproof performance of the building.
[0003] In the prior art, especially the above-mentioned CN219281333U disclosed a rotatable post-cast strip closed cover plate, which provides two layers of waterproof technology, but it is difficult for the second water guide groove 401 therein to be in close contact with the upper edge of the side wall of the post-cast strip when in use, so it cannot achieve the desired secondary drainage effect for water entering from the concrete surfaces on both sides. In addition, the device is convenient for turnover in theory because the two parts are folded by hinges, but in use, the length of the post-cast strip is not fixed, so the "turnover" achieved in this way is not a real turnover.
[0004] A post-cast strip closing cover plate is provided. The structure adopts an assembly form, and the required parts are divided into multiple parts. Each part can be made by existing steel rolling technology. When used, it is cut according to the on-site conditions. The multiple parts are simply assembled to achieve the closure of the post-cast strip and can drain the water on the concrete surface on both sides as soon as possible. The entire cover plate can be firmly fixed on the post-cast strip without deflection, shaking or detachment. Utility Model Content
[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a post-cast strip closing cover plate, which effectively solves the problem that the post-cast strip closing cover plate in the prior art cannot quickly drain the water on the concrete surface on both sides.
[0006] The technical solution is to include a flat plate with a pressure plate on the upper side of the flat plate, the cross-section of the pressure plate is a trapezoidal shape with low sides and high middle, long strips parallel to the pressure plate are fixed on the lower end surfaces on both sides of the pressure plate, the side of the long strip close to the center of the flat plate is bent upward and fixed to the pressure plate, and a U-shaped cavity opening outward is formed between the long strip and the pressure plate, and snap-fit plates with openings facing inward are provided on both sides of the flat plate, the cross-section of the snap-fit plates is U-shaped, the upper side plates of the snap-fit plates are inserted into the U-shaped cavity, and a vertical plate is fixed on the lower side of the lower side plate of the snap-fit plate close to the center of the flat plate, and the lower end of the vertical plate is bent toward the side away from the center of the flat plate to form a U-shaped structure.
[0007] Furthermore, a screw is fixed to the upper end of the flat plate, the upper end of the screw passes through the pressure plate and is placed on the upper end of the pressure plate, and a nut is screwed on the part of the screw placed on the upper end of the pressure plate.
[0008] Furthermore, a spacer is provided between the pressing plate and the nut.
[0009] The utility model has an ingenious structure. The structure adopts an assembly form, and the required parts are divided into multiple parts. Each part can be made by existing steel rolling technology. When in use, it can be cut according to the on-site conditions and the multiple parts can be simply assembled to achieve the closure of the post-cast strip and can drain the water on the concrete surfaces on both sides as soon as possible. The entire cover plate can be firmly fixed on the post-cast strip without deflection, shaking or detachment. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 This is a state diagram of the utility model when in use. DETAILED DESCRIPTION
[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0013] Depend on Figure 1 to Figure 2 The utility model includes a flat plate 1, a pressing plate 2 is provided on the upper side of the flat plate 1, the cross section of the pressing plate 2 is a trapezoidal shape with low sides and high middle, long strips 3 parallel to the pressing plate 2 are fixed on the lower end surfaces on both sides of the pressing plate 2, the side of the long strip 3 close to the center of the flat plate 1 is bent upward and fixed to the pressing plate 2, and a U-shaped cavity opening outward is formed between the long strip 3 and the pressing plate 2, and snap-fit plates 4 with openings facing inward are provided on both sides of the flat plate 1, the cross section of the snap-fit plates 4 is U-shaped, the upper side plates of the snap-fit plates 4 are inserted into the U-shaped cavity, and the lower side plates of the snap-fit plates 4 close to the center of the flat plate 1 are fixed with vertical plates 5, and the lower ends of the vertical plates 5 are bent toward the side away from the center of the flat plate 1 to form a U-shaped structure.
[0014] In order to make the two side locking plates 4 open to each other and achieve the close fit between the bending part of the lower end of the vertical plate 5 and the side wall of the post-cast strip, a screw rod 6 is fixed to the upper end of the flat plate 1, and the upper end of the screw rod 6 passes through the pressing plate 2 and is placed on the upper end of the pressing plate 2. A nut 7 is screwed on the part of the screw rod 6 placed on the upper end of the pressing plate 2.
[0015] In order to prevent the pressing plate 2 from being damaged by the nut 7 , a spacer 8 is provided between the pressing plate 2 and the nut 7 .
[0016] It is worth noting that the plate 1 should not be severely deformed during use; the pressing plate 2 has a certain elasticity, and when the nut 7 presses the pressing plate 2 downward, the edges of both sides of the pressing plate 2 move outward.
[0017] When in use, cut the raw materials of appropriate length, then place the pressing plate 2 on the flat plate 1, and preliminarily screw the nut 7 so that the pressing plate 2 and the flat plate 1 are closely attached to each other, then pick up the flat plate 1 and the pressing plate 2 at the same time, and insert the upper side of the snap-fit plate 4 into the U-shaped cavity formed between the long plate 3 and the pressing plate 2, and then place it on the post-cast strip. At this time, screw the nut 7, and the nut 7 moves downward to deform the pressing plate 2, and the left and right sides of the pressing plate 2 extend outward, driving the snap-fit plate 4 to move outward during the extension, and the vertical plate 5 at the lower end of the snap-fit plate 4 also moves outward, and the bending part of the lower end of the vertical plate 5 gradually fits with the side wall of the post-cast strip. After fitting, one is that the entire device can be firmly fixed on the post-cast strip, and the other is that the water invading the concrete surface on both sides can be quickly discharged to avoid adverse effects on the construction quality of the post-cast strip in the later stage.
[0018] The utility model has an ingenious structure. The structure adopts an assembly form, and the required parts are divided into multiple parts. Each part can be made by existing steel rolling technology. When in use, it can be cut according to the on-site conditions and the multiple parts can be simply assembled to achieve the closure of the post-cast strip and can drain the water on the concrete surfaces on both sides as soon as possible. The entire cover plate can be firmly fixed on the post-cast strip without deflection, shaking or detachment.
