Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roof concrete pouring, in particular to a speed reduction structure for roof concrete pouring. Background Technique
[0002] In the current residential construction process, in order to achieve a beautiful appearance or increase the drainage volume to prevent water accumulation and snow accumulation, the roof is often designed as an inclined roof. However, during the concrete pouring process of the inclined roof, if the slump of the concrete is relatively large, it is very easy to cause the concrete to have pitted surfaces and be accompanied by cracks. Therefore, construction workers often increase the slump, increase the cement paste content, and reduce the aggregate particles, and finally finish troweling to ensure a smooth and dense finish. However, another problem appears, that is, when the slump increases, the flow velocity of the concrete fluid increases, and it cannot accumulate on the inclined roof and all flows downward from the inclined roof. Summary of the Invention
[0003] The purpose of the utility model is to solve the problems raised in the background technique, and provide a speed reduction structure for roof concrete pouring.
[0004] The technical solution of the utility model to achieve the above purpose is as follows:
[0005] A speed reduction structure for roof concrete pouring, including a wire mesh, a support, a connecting cylinder, a connecting hole, a column, a clamping block, a spring, and a retaining piece; each cross intersection of the wire mesh is fixedly connected to a support, each support is fixedly connected to a connecting cylinder, a connecting hole is opened on the connecting cylinder, there are two connecting holes in total and they are equally spaced on the lower side of the connecting cylinder, the column is sleeved on the connecting cylinder, each column is slidably connected to two clamping blocks respectively, the two clamping blocks are equally spaced inside the column, the shape of the clamping block is trapezoidal and the inclined surface faces downward, the spring is located inside the column and one end is fixedly connected to the column, the other end of the spring is fixedly connected to the clamping block, the two clamping blocks are respectively clamped in the two connecting holes, each column is fixedly connected to two retaining pieces respectively, and the retaining pieces are located on both sides of the column and are on the same horizontal line.
[0006] Preferably, the retaining piece is provided with a reinforcing rib, the reinforcing rib is fixedly connected to the retaining piece, and the reinforcing rib is fixedly connected to the column.
[0007] Preferably, the retaining piece is provided with convex points, and the convex points are fixedly connected to the retaining piece.
[0008] Preferably, the bottom of the support is provided with an anti-slip gasket, and the anti-slip gasket is fixedly connected to the support.
[0009] The utility model provides a speed reduction structure for roof concrete pouring, which has the following beneficial effects:
[0010] Through its structural design, the device is installed on the roof when pouring roof concrete. Each cross of the wire mesh is connected to a support, and each support corresponds to a connecting tube. After the wire mesh is installed, the construction personnel will put the column on the connecting tube. When installing, the baffles on two adjacent columns located on the same horizontal line are also on the same horizontal line. In the process of the column being installed downwardly on the connecting tube, the inclined surface of the block will push the block to shrink into the column. When the column is completely installed on the connecting tube, the position of the block is aligned with the position on the connecting tube. The positions of the connecting holes correspond, and the spring pushes the card block to pop out and fall into the connecting hole to fix the column on the connecting tube, completing the installation of the column, ensuring that the baffle will not be washed away when the concrete flows, and ensuring that some aggregates will be blocked by the baffle, so as to make the concrete denser and avoid cracking. Repeat the above operation and install a column on each connecting tube before starting the concrete pouring of the roof. During pouring, the baffle on the column will reduce the flow rate of the concrete, achieving the effect of self-flowing vibration and compaction of the concrete, thereby reducing the risk of cracking, reducing the risk of leakage, and reducing the cost of later repairs.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution: a slow-down structure for roof concrete pouring, including a wire mesh 1, a support 2, a connecting cylinder 3, a connecting hole 4, a column 5, a clamping block 6, a spring 7, and a retaining piece 8; each cross intersection of the wire mesh 1 is fixedly connected to a support 2, each support 2 is fixedly connected to a connecting cylinder 3, a connecting hole 4 is opened on the connecting cylinder 3, there are two connecting holes 4 in total and they are equidistantly distributed on the lower side of the connecting cylinder 3, the column 5 is sleeved on the connecting cylinder 3, each column 5 is slidably connected to two clamping blocks 6, the two clamping blocks 6 are equidistantly distributed inside the column 5, the shape of the clamping block 6 is trapezoidal with the inclined surface facing downwards, the spring 7 is located inside the column 5 and one end is fixedly connected to the column 5, the other end of the spring 7 is fixedly connected to the clamping block 6, the two clamping blocks 6 are respectively clamped in the two connecting holes 4, each column 5 is fixedly connected to two retaining pieces 8, and the retaining pieces 8 are located on both sides of the column 5 and are on the same horizontal line.
[0018] In the present utility model, reinforcing ribs 9 are provided on the retaining piece 8, the reinforcing ribs 9 are fixedly connected to the retaining piece 8, and the reinforcing ribs 9 are fixedly connected to the column 5. By the reinforcing ribs 9 on the retaining piece 8, the mechanical strength of the connection between the retaining piece 8 and the column 5 can be improved, preventing the connection part from being damaged due to excessive concrete pressure.
[0019] In the present utility model, bumps 10 are provided on the retaining piece 8, and the bumps 10 are fixedly connected to the retaining piece 8. By the bumps 10 on the retaining piece 8, the friction coefficient of the surface of the retaining piece 8 is increased, which helps to better block the aggregates in the concrete and prevent them from sliding down quickly.
[0020] In the present utility model, an anti-slip gasket 11 is provided at the bottom of the support 2, and the anti-slip gasket 11 is fixedly connected to the support 2. By the anti-slip gasket 11 at the bottom of the support 2, the friction between the support 2 and the roof is increased, avoiding the movement of the support 2 during the concrete pouring process.
[0021] In this embodiment: When pouring the roof concrete, the wire mesh 1 is laid on the roof. A support 2 is connected to each cross intersection on the wire mesh 1. Each support 2 corresponds to a connecting cylinder 3. The anti-slip gasket 11 at the bottom of the support 2 increases the friction between the support 2 and the roof, preventing the support 2 from moving during the concrete pouring process. After the wire mesh 1 is laid, the construction workers sleeve the column 5 onto the connecting cylinder 3. During the sleeving process, the baffles 8 on two adjacent columns 5 located on the same horizontal line in the transverse direction are also on the same horizontal line. When the column 5 is sleeved downward onto the connecting cylinder 3, the inclined surface of the clamping block 6 will push the clamping block 6 to contract into the column 5. When the column 5 is completely sleeved onto the connecting cylinder 3, the position of the clamping block 5 corresponds to the position of the connecting hole 4 on the connecting cylinder 3. The spring 7 pushes the clamping block 5 to pop out and fall into the connecting hole 4, thus fixing the column 5 on the connecting cylinder 3, completing the installation of the column 5, ensuring that the baffle 8 will not be washed away when the concrete flows, ensuring that some aggregates will be blocked by the baffle 8, making the concrete denser and avoiding cracking. The reinforcing rib 9 on the baffle 8 can improve the mechanical strength of the connection between the baffle 8 and the column 5, preventing the connection part from being damaged due to excessive concrete pressure. After repeating the above operation to install a column 5 on each connecting cylinder 3, the roof concrete pouring can begin. The convex points 10 on the baffle 8 increase the friction coefficient of the surface of the baffle 8, helping to better block the aggregates in the concrete and prevent them from sliding down quickly.
