Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a post-cast strip concrete isolation device. Background Art

[0002] During the casting of mass concrete, in order to avoid affecting the overall strength and stability of the concrete structure due to uneven settlement of the foundation, it is often necessary to set post-cast strips between the concretes. After the uneven settlement of the foundation ends, concrete is then cast in the post-cast strips.

[0003] In order to set post-cast strips between concrete structures, a concrete isolation device is required to partition the concrete during the casting of concrete. In the existing construction methods, wire meshes are often tied to the surface of steel bars as the concrete isolation device to isolate the concrete.

[0004] For the existing post-cast strip concrete isolation device, the wire mesh needs to be tied on site, and the construction process is complex. Moreover, the wire mesh is easily broken, resulting in it being unable to be recycled after demolition, and the construction cost is relatively high. Summary of the Utility Model

[0005] An object of the utility model is to solve the problems of complex construction and high recycling cost of the existing post-cast strip concrete isolation device.

[0006] In particular, the embodiments of the present application provide a post-cast strip concrete isolation device, including:

[0007] A body for isolating concrete. The body is a long strip-shaped panel, and first bending parts for fixing the body are provided on both sides in the height direction of the body. The first bending parts are arranged on the side of the body away from the concrete, and fish-scale holes are provided on the body;

[0008] A plurality of stiffening structures are arranged at intervals along the length direction of the body. Both ends of each stiffening structure are fixedly connected to the two first bending parts respectively.

[0009] Further, the stiffening structure includes two rigid plates intersecting in an X shape, and abutting plates for abutting against the first bending parts are provided at the ends of the two rigid plates.

[0010] Further, a second bending part penetrating the length direction of the body is provided in the middle in the height direction of the body.

[0011] Further, the second bending part includes a vertical part and two inclined parts. The inclined parts are located on both sides in the height direction of the vertical part, and the included angle between each inclined part and the vertical part is an obtuse angle.

[0012] Further, drain holes are provided on the second bending part.

[0013] Further, the drain hole is a circular hole.

[0014] Further, the rigid plate is a galvanized iron plate.

[0015] Further, one end of the body in the length direction is provided with a socket, and the other end is provided with a tongue. The tongue is arranged on the side of the body close to the concrete. The tongue includes a fixed end connected to the body and a suspended end corresponding to the fixed end. The suspended end is arranged on the side close to the socket. When the post-cast strip concrete isolation devices are connected end to end in the length direction, the tongue is inserted into the socket.

[0016] Further, both the socket and the tongue are circular.

[0017] Further, the body is provided with multiple groups of the sockets and the tongues aligned in the length direction of the body, and the multiple groups of sockets and tongues are symmetrically arranged in the middle of the body in the height direction.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The concrete is isolated by using a long strip plate, and the installation is realized in cooperation with a fixing frame, making the construction more convenient. At the same time, it is not easily damaged after demolition and can be reused. Meanwhile, by setting a stiffening structure, the stiffness of the post-cast strip concrete isolation device is enhanced, avoiding deformation after pouring concrete.

[0020] 2. By arranging a tongue and a socket on the body, the connection of the concrete isolation device is facilitated, improving the construction efficiency. Description of the Drawings

[0025] To make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, the following will, with reference to the accompanying drawings, provide a detailed description of the specific embodiments of the present application. It can be understood that the specific embodiments described herein are only for explaining the present application and not for limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0026] The terms "comprising" and "having" in the present application and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0027] As Figure 1 shown, the post - casting belt concrete isolation device of the present utility model includes a body 1 for isolating concrete and a plurality of stiffening structures 4 for preventing the body 1 from deforming. The body 1 is a long - strip panel. During use, the body 1 needs to be vertically fixed on the ground or other objects along its length direction. For this purpose, first bending portions 2 for fixing the body 1 are provided on both sides of the body 1 in the length direction, and the first bending portions 2 are bent away from the concrete side. By placing the fixing frame within the bent portion and then fixing the fixing frame on the ground or other objects, the installation of the body 1 can be achieved. In one embodiment, in order to improve the bonding force of the concrete surface, fish - scale holes 3 are provided on the body 1. The fish - scale holes 3 are formed by stamping the body. While forming a long - strip hole on the body through stamping, a guide plate protruding from the body and used for guiding the water flow is formed on one side of the hole.

[0028] By providing the fish - scale holes 3, on the one hand, the discharge of excess water after concrete pouring is enhanced. On the other hand, due to the existence of the guide plate, protrusions will be formed on the surface of the poured concrete after concrete pouring. During the subsequent post - casting belt pouring process, the concrete in the post - casting belt intersects with the protrusions, enhancing the bonding force between the post - casting belt and the existing concrete body.

[0029] Since the concrete is heavy itself, a strong lateral pressure is exerted on the body 1 during the concrete pouring process. To prevent the body 1 from deforming under the action of the concrete lateral pressure, resulting in the concrete structure after pouring not meeting the design requirements, a plurality of stiffening structures 4 are arranged at intervals along the length direction of the body 1, and both ends of the stiffening structures 4 are fixedly connected to the two first bending portions 2 respectively. By providing the stiffening structures 4, the bending strength of the body 1 in the direction perpendicular to the plate surface is enhanced.

[0030] When installing the post-cast strip concrete isolation device, only need to vertically place the body 1 along the length direction. After fixing it through the fixing frame, concrete pouring can be carried out. When it needs to be removed, just use a crowbar to pry along the joint surface between the body 1 and the concrete, then separation can be achieved without damaging the body 1, and it can be reused, reducing the construction cost.

[0031] In one embodiment, the stiffening structure 4 is composed of two rigid plates crossing in an X shape. At the ends of the two rigid plates, there are abutting plates 5 for abutting against the first bending part 2. The abutting plates 5 are connected to the ends of the rigid plates by welding. The abutting plates 5 are limited within the first bending part 2. When installing the stiffening structure 4 within the first bending part 2, it can be installed sequentially from one side of the body 1 along the length direction. In other embodiments, the stiffening structure 4 can also be in the shape of "I-shaped", "one-shaped" or "square". Other shapes of the stiffening structure 4 that can achieve the same effect all fall within the protection scope of the present utility model and will not be elaborated here.

[0032] By setting the stiffening structure 4 in an X shape, the upper and lower ends and the middle part of the body 1 can all play a role in reinforcement. At the same time, since the X-shaped stiffening structure 4 is formed by the crossing of two steel plates, the strength at the middle crossing position is relatively high, enhancing the anti-side bending performance of the stiffening structure 4.

[0033] In order to further enhance the anti-bending ability of the body 1 part, in one embodiment, the body 1 is a galvanized iron plate. Since the overall stiffness of the iron plate is relatively high, it is not easy to deform under the action of the lateral pressure of the concrete. At the same time, because the surface of the iron plate is coated with zinc, the anti-corrosion performance of the iron plate is enhanced, avoiding the surface corrosion after the body 1 contacts the concrete, and improving the durability of the post-cast strip concrete isolation device. In other embodiments, the body 1 can also be made of stainless steel plate. Other materials that can ensure the body 1 has strong stiffness and at the same time has corrosion resistance all fall within the protection scope of the present utility model.

[0034] In order to enhance the drainage capacity after concrete pouring and, at the same time, further enhance the bonding force of the concrete surface. In one embodiment, a second bending portion 6 penetrating the length direction of the body 1 is provided in the middle of the body 1 in the height direction. The second bending portion 6 includes a vertical portion 61 and two inclined portions 62. The vertical portion 61 is located in the middle of the body 1 in the height direction, and the inclined portions 62 are located on both sides of the vertical portion 61 in the length direction. Circular drainage holes 7 are provided on the second bending portion 6. When the concrete is built, the excess water flows to the second bending portion 6 under the action of gravity and is discharged through the drainage holes 7 provided on the second bending portion 6. Since the drainage holes 7 are circular, it is not easy to cause water flow blockage during drainage, ensuring the drainage capacity of the second bending portion 6. In other embodiments, when the aggregate of the concrete is coarser, the shape of the drainage holes 7 on the second bending portion 6 can also be changed accordingly, for example, it can be set to a square or a triangle.

[0035] By setting the second bending portion 6 into two inclined portions 62 and a vertical portion 61, the contact area between the second bending portion 6 and the concrete surface is increased, enhancing the drainage capacity of the second bending portion 6.

[0036] As Figure 2 shown, one end of the body 1 in the length direction is provided with a socket 9, and the other end is provided with a tongue 8. The tongue 8 is arranged on the side of the body 1 close to the concrete. The tongue 8 includes a fixed end connected to the body 1 and a suspended end corresponding to the fixed end. The suspended end is arranged on the side close to the socket 9. When the post-cast strip concrete isolation device is connected end to end in the length direction, the tongue 8 is inserted into the socket 9 to achieve the end-to-end connection of the post-cast strip concrete isolation device, eliminating the need for welding again and facilitating construction. In one embodiment, the tongue 8 and the socket 9 are circular. When the tongue 8 and the socket 9 are inserted, the insertion is more convenient, and the insertion will not be hindered due to the angle matching problem between the tongue 8 and the socket 9. At the same time, the tongue 8 and the socket 9 are symmetrically arranged in the middle of the body 1 in the height direction, making the force more uniform and the connection more stable after the post-cast strip isolation concrete device is connected.
