Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a fixing device for concrete pouring on a large slope. Background Technology
[0002] With the development of the construction industry, architectural styles are constantly evolving, and roof forms are no longer limited to traditional shapes. However, during the concrete pouring process, many steeply sloping roofs experience concrete flow down the slope due to the gradient, resulting in a reduction in the amount of concrete in the upper part of the roof. This necessitates intervention from construction workers, increasing their workload, posing safety hazards during slope construction, and making it difficult to guarantee construction quality. Therefore, there is an urgent need for a concrete pouring fixing device that can reduce the flowability of concrete on steeply sloping roofs, fix the concrete slab surface and subsequent concrete protective layer, improve roof pouring quality, and reduce safety hazards. Utility Model Content
[0003] The purpose of this invention is to provide a fixing device for concrete pouring on steep slopes, which can reduce the fluidity of concrete on steep slope roofs, fix the concrete on the slab surface and the subsequent concrete protective layer, improve the quality of roof pouring, and reduce safety hazards.
[0004] The present invention adopts the following technical solution:
[0005] A large-slope concrete pouring fixing device includes two fixing plates, which are arranged at intervals in the vertical direction. The bottom fixing plate is provided with multiple fixing ribs, the top of which passes through the upper fixing plate and is fixedly connected to the upper fixing plate. A barrier net is provided between the upper and lower fixing ribs, and the barrier net extends to both sides in the horizontal direction.
[0006] Preferably, the fixing rib and the fixing plate are fixedly connected by welding.
[0007] Preferably, the fixing plate is a rectangular steel plate.
[0008] Preferably, the barrier net is made of wire mesh.
[0009] Preferably, the fixing ribs are arranged alternately on both sides of the fixing plate, along the direction of the extension of the barrier net, forming a space between the fixing ribs on both sides for placing the barrier net.
[0010] Preferably, the barrier net has reinforcing ribs along its length on one side.
[0011] Preferably, multiple reinforcing ribs are spaced apart along the height direction of the barrier net.
[0012] Preferably, the reinforcing ribs are fixedly connected to the barrier net by tie wires.
[0013] Preferably, the reinforcing bar and the fixing bar are fixedly connected.
[0014] Preferably, the distance between the upper and lower fixing plates is matched with the height of the barrier net.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets the fixing plate between the bottom and top steel mesh of the roof with a large slope, and sets the fixing bars on the fixing plate. By setting the barrier net in the space formed by the fixing bars, it can effectively block the concrete, reduce the flow of concrete on the roof with a large slope, improve the pouring quality, reduce the frequency of manual intervention and rework, and reduce the safety hazards caused by rework.
[0016] This application utilizes a barrier net to intercept the flow of concrete. The horizontally extending barrier net forms a flow-blocking barrier, effectively dividing the concrete flow, reducing its overall kinetic energy along the slope, and preventing aggregate rolling and mortar segregation. The upper and lower fixing plates are connected by fixing bars to form a three-dimensional support frame, preventing lateral slippage during concrete pouring and ensuring uniform protective layer thickness.

[0018] Figure 2 This is a three-dimensional structural diagram of an embodiment of this application. Detailed Implementation
[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0020] like Figures 1 to 2 As shown, the present invention discloses a concrete pouring fixing device for steep slopes, comprising two fixing plates 1. The fixing plates 1 are preferably rectangular steel plates with a preferred size of 200×200mm. The two fixing plates 1 are arranged vertically at intervals. Multiple fixing ribs 2 are provided on the bottom fixing plate 1. The top of each fixing rib 2 passes through the upper fixing plate 1 and is fixedly connected to it. Preferably, the fixing ribs 2 are connected to the two fixing plates 1 by welding. A barrier net 3 is provided between the upper and lower fixing ribs 2, with the distance between the upper and lower fixing plates 1 preferably matching the height of the barrier net 3. The barrier net 3 can be made of locally sourced wire mesh and extends horizontally to both sides. By setting the barrier net 3, this application can effectively block the concrete, reduce the flow of concrete on steep slopes, improve pouring quality, reduce the frequency of rework, and lower the safety hazards caused by rework.
[0021] Furthermore, the fixing ribs 2 are arranged symmetrically on both sides of the fixing plate 1, staggered one after the other along the direction of the barrier net 3, forming a space between the fixing ribs 2 on both sides for placing the barrier net 3. The staggered arrangement of the fixing ribs 2 increases the contact surface with the barrier net 3 in the length direction, improving the stability of the barrier net 3. In addition, a reinforcing rib 4 is provided on one side of the barrier net 3 along its length direction. Multiple reinforcing ribs 4 are spaced apart along the height direction of the barrier net 3, and the specific number is flexibly adjusted according to the height of the reinforcing ribs 4. The setting of the reinforcing ribs 4 can provide support for the barrier net 3, reduce the probability of deformation under the impact of concrete, and improve the interception effect of concrete. The reinforcing ribs 4 and the barrier net 3 are preferably fixedly connected by wire. The reinforcing ribs 4 and the fixing ribs 2 can be fixedly connected by wire or welding to ensure the stability of the reinforcing ribs 4 and ensure the reinforcement effect of the barrier net 3.
[0022] In use, the bottom fixing plate 1 is placed on the bottom layer of the roof reinforcement mesh, and the upper fixing plate 1 is placed below the top layer of the reinforcement mesh. The concrete is intercepted by the barrier net 3, which extends horizontally to form a flow barrier, effectively dividing the concrete flow, reducing its overall kinetic energy along the slope, and preventing aggregate rolling and mortar segregation. The upper and lower fixing plates 1 are connected by fixing bars 2 to form a three-dimensional support frame, preventing lateral slippage during concrete pouring and ensuring uniform protective layer thickness. Simultaneously, this device can perform three functions: stirrup support, barrier net 3 fixation, and embedded part anchoring, replacing traditional step-by-step construction (such as separately installing wire mesh and stirrups), reducing labor and material waste. The steel plates, reinforcing bars, and wire mesh are all made from common construction materials, and their dimensions can be flexibly adjusted according to the slope (e.g., the length of the fixing bars 2 is customized according to the roof construction method), requiring no special processing and exhibiting strong on-site adaptability.
[0023] Furthermore, the fixing ribs 2 extending through the fixing plate 1 can be directly used as installation bases for roof tiles, lightning protection strips, and other ancillary facilities, avoiding structural damage from secondary drilling. The exposed top portion of the fixing ribs 2 can serve as a vibratory guide rail or a leveling elevation control point, simplifying the leveling work for steep slope surfaces and demonstrating strong practicality. This application employs a modular design, with the fixing plates 1 arranged in sections (1-1.5m / section recommended), adapting to curved roof surfaces through hinges; the barrier net 3 can be expanded and spliced to cover irregularly shaped areas, making it widely applicable.
