[0002] In industrial and civil building construction, the construction of the whole building cannot be without the floor construction, and the floor thickness control is an important part in the floor construction process, and the floor thickness control is indispensable for the engineering quality and cost.

[0003] The utility model discloses a cast-in-place concrete slab thickness control prefabricated component discloses a cast-in-place concrete slab thickness control prefabricated component, including concrete component, horizontal fixed reinforcement, concrete component is the horizontal cylinder of bottom, horizontal fixed reinforcement is fixed at one third height from concrete component bottom, four horizontal fixed reinforcements are symmetrically arranged on the horizontal section of concrete component, and one end is fixed in concrete component, and the other end is exposed outside concrete component, and concrete component is evenly arranged in square array between main beam and secondary beam, and horizontal fixed reinforcement is fixed with horizontal distribution muscle.

Utility model content

[0005] The cast-in-place concrete slab thickness control prefabricated component in the above, the concrete is poured into the PVC pipe to make the concrete component, the concrete component is taken out from the PVC pipe after waiting for the initial condensation of the concrete, then the fixed reinforcement is inserted into the concrete component, and then the final condensation is waited, but the concrete component is taken out after the initial condensation, which does not mean that the concrete has completely hardened, the concrete component is prone to deformation, cannot be used, and causes the problem of resource waste.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] A precast component for controlling the thickness of cast-in-place concrete slabs includes four arc-shaped mold plates. The arc-shaped mold plates are provided with connecting components for forming mold tubes. The connecting components include two first connecting blocks fixedly connected to one side wall of the arc-shaped mold plate, and two second connecting blocks adapted to the first connecting blocks fixedly connected to the other side wall of the arc-shaped mold plate. A fixing bolt is provided on one side wall of the first connecting block, and a fixing sleeve is fixedly connected to one side wall of the second connecting block. The fixing bolt passes through the first connecting block and the second connecting block respectively and is threadedly connected to the fixing sleeve. Each pair of arc-shaped mold plates has a matching arc-shaped hole at one of their opposite ends.

[0008] By adopting the above technical solution, during use, the two ends of the four arc-shaped mold plates are aligned with each other, and the first connecting block and the second connecting block are aligned with each other. Then, the fixing bolts are passed through the first connecting block and the second connecting block, and the fixing bolts are threaded to the fixing sleeve, connecting and fixing the four arc-shaped mold plates together to form a mold tube. At the same time, the arc-shaped holes are aligned with each other to form through holes. Then, the reinforcing bars are inserted into the through holes, and the concrete component is poured. After the concrete has set, the fixing bolts are removed, the four arc-shaped mold plates are separated, the mold tube is disassembled, and the concrete component is taken out. This avoids the problem of having to take the concrete out of the mold when it has just set, insert the reinforcing bars, and wait for it to set, which can easily cause the concrete component to deform and become unusable, resulting in a waste of resources.

[0009] Optionally, a U-shaped frame is fixedly connected to one side wall of the first connecting block, the fixing bolt is located inside the U-shaped frame, and a limit rod is fixedly connected to the end of the fixing bolt away from the first connecting block. The limit rod passes through the U-shaped frame and is fixedly connected to a limit plate.

[0010] By adopting the above technical solution, rotating the limiting plate causes the limiting rod to rotate, which in turn drives the fixing bolt to rotate. During demolding, the fixing bolt can be moved into the U-shaped frame to prevent it from falling off and avoid losing it, thus preventing resource waste.

[0011] Optionally, the length of the limiting rod is greater than the length of the fixing bolt.

[0012] By adopting the above technical solutions, it is possible to prevent the nut end of the fixing bolt from not abutting against the first connecting block after the limiting plate and the U-shaped frame are abutted when the limiting rod is too short. This would result in a gap between the first and second connecting blocks, making it impossible for the arc mold plates to fit tightly together. Consequently, when pouring concrete components, concrete would seep out from the gap between the arc mold plates, affecting the quality.

[0013] Optionally, the bottom end of the arc-shaped mold plate is provided with a mounting plate, and the mounting plate is provided with an annular groove adapted to the arc-shaped mold plate.

[0014] By adopting the above technical solution, each arc mold plate can be quickly aligned to form a mold tube by inserting all the arc mold plates into the annular groove, which facilitates the connection between the arc mold plates.

[0015] Optionally, the sidewalls of the arc-shaped mold plate are all fixedly connected with arc-shaped support tubes at the arc-shaped holes.

[0016] By adopting the above technical solution, the arc-shaped support pipe can support the steel bars inserted into the arc-shaped hole, preventing the steel bars from tilting.

[0017] Optionally, an anti-wear washer is fitted onto the fixing bolt, and the anti-wear washer is located on the side of the first connecting block away from the second connecting block.

[0018] By adopting the above technical solution, the anti-wear washer can prevent the nut end of the fixing bolt from directly contacting the first connecting block and causing wear to the first connecting block during rotation.

[0019] Optionally, the side wall of the limiting plate away from the limiting rod is provided with a connecting groove for connecting with an external driving device.

[0020] By adopting the above technical solution, the external drive device can be easily connected to the limit plate through the connecting groove, and the fixing bolt can be rotated quickly.

[0021] Optionally, one sidewall of the arc-shaped mold plate is coated with an anti-sticking agent.

[0022] By adopting the above technical solutions, the anti-sticking agent can effectively prevent concrete components from sticking to the mold tube, making demolding easier.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. This application utilizes the cooperative arrangement of structures such as the first connecting block, the second connecting block, and the fixing bolts. In use, by aligning the two ends of the four arc-shaped mold plates with each other, the first connecting block and the second connecting block are aligned with each other. Then, the fixing bolts are passed through the first connecting block and the second connecting block, and the fixing bolts are threadedly connected to the fixing sleeves, thus connecting and fixing the four arc-shaped mold plates together to form a mold tube. At the same time, the arc-shaped holes are aligned with each other to form through holes. Then, the reinforcing bars are inserted into the through holes, and the concrete component is poured. After the concrete has set, the fixing bolts are removed, the four arc-shaped mold plates are separated, the mold tube is disassembled, and the concrete component is taken out. This method avoids the problem of having to take the concrete out of the mold when it has initially set, insert the reinforcing bars, and wait for it to set. This is because the concrete component is prone to deformation and cannot be used, which leads to a waste of resources.

[0025] 2. By rotating the limiting plate, the limiting rod is rotated, which in turn drives the fixing bolt to rotate. During demolding, the fixing bolt can be moved into the U-shaped frame to prevent it from falling off and to avoid loss of the fixing bolt, which would otherwise lead to waste of resources.

[0031] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Please see Figure 1 , Figure 2 and Figure 3 A precast component for controlling the thickness of cast-in-place concrete slabs includes four arc-shaped mold plates 1, which can form a mold tube for casting concrete components. The arc-shaped mold plates 1 are provided with connecting components for forming the mold tube. The connecting components include a first connecting block 2, a second connecting block 3, a fixing bolt 4, a fixing sleeve 5, and an arc-shaped hole 6.

[0033] The first connecting block 2 is provided in four sets. Each set of the first connecting block 2 is fixedly connected to one side wall of the arc-shaped mold plate 1. There are two first connecting blocks 2 in each set, located above and below the arc-shaped mold plate 1 respectively. The second connecting block 3 is provided in four sets. Each set of the second connecting block 3 is fixedly connected to the other side wall of the arc-shaped mold plate 1 and the second connecting block 3 is adapted to the first connecting block 2. Multiple fixing bolts 4 are provided and located on the side wall of the first connecting block 2 away from the second connecting block 3 respectively. Multiple fixing sleeves 5 are provided and fixedly connected to the side wall of the second connecting block 3 away from the first connecting block 2 respectively. The fixing bolts 4 pass through the first connecting block 2 and the second connecting block 3 respectively and are threadedly connected to the fixing sleeves 5. Multiple arc-shaped holes 6 are provided and are opened at the opposite ends of every two arc-shaped mold plates 1 and are adapted to each other. After the four arc-shaped mold plates 1 form a mold tube, every two arc-shaped holes 6 form a through hole for inserting steel bars and connecting them to the concrete component.

[0034] In use, the ends of the four arc-shaped mold plates 1 are aligned with each other, and the first connecting block 2 and the second connecting block 3 are aligned with each other. Then, the fixing bolt 4 is passed through the first connecting block 2 and the second connecting block 3, and the fixing bolt 4 is threadedly connected to the fixing sleeve 5. The four arc-shaped mold plates 1 are connected and fixed to each other to form a mold tube. At the same time, the arc-shaped holes 6 are aligned with each other to form a through hole. Then, the reinforcing bars are inserted into the through holes, and the concrete component is poured. After the concrete has set, the fixing bolt 4 is removed, the four arc-shaped mold plates 1 are separated, the mold tube is disassembled, and the concrete component is taken out. This method avoids the problem of having to take the concrete out of the mold when it has just set, insert the reinforcing bars, and wait for it to set. This is because the concrete component is prone to deformation and cannot be used, which leads to a waste of resources.

[0035] Reference Figure 1 and Figure 4 A U-shaped frame 7 is fixedly connected to one side wall of the first connecting block 2. The fixing bolt 4 is located inside the U-shaped frame 7. The end of the fixing bolt 4 away from the first connecting block 2 is fixedly connected to a limiting rod 8. The limiting rod 8 passes through the U-shaped frame 7 and is fixedly connected to a limiting plate 9. Rotating the limiting plate 9 causes the limiting rod 8 to rotate, which in turn drives the fixing bolt 4 to rotate. During demolding, the fixing bolt 4 can be moved into the U-shaped frame 7 to prevent the fixing bolt 4 from falling off and to avoid loss of the fixing bolt 4, which would result in resource waste.

[0036] Reference Figure 1 The length of the limiting rod 8 is greater than the length of the fixing bolt 4. This prevents the nut end of the fixing bolt 4 from not abutting against the first connecting block 2 after the limiting plate 9 abuts against the U-shaped frame 7 when the limiting rod 8 is too short. This would result in a gap between the first connecting block 2 and the second connecting block 3, making it impossible for the arc mold plates 1 to fit tightly together. Consequently, when pouring concrete components, concrete would seep out from the gap between the arc mold plates 1, affecting the quality.

[0037] Reference Figure 1 and Figure 2 The bottom end of the arc-shaped mold plate 1 is provided with a mounting plate 10. The mounting plate 10 has an annular groove 11 that is adapted to the arc-shaped mold plate 1. By inserting the arc-shaped mold plates 1 into the annular groove 11, each arc-shaped mold plate 1 can be quickly aligned to form a mold tube, which facilitates the connection between the arc-shaped mold plates 1.

[0038] Reference Figure 1 and Figure 3 Arc-shaped support pipes 12 are fixedly connected to the side walls of the arc-shaped mold plate 1 at the arc-shaped holes 6. The arc-shaped support pipes 12 can support the steel bars inserted into the arc-shaped holes 6 and prevent the steel bars from tilting.

[0039] Reference Figure 4 The fixing bolt 4 is fitted with an anti-wear washer 13. The anti-wear washer 13 is located on the side of the first connecting block 2 away from the second connecting block 3. The anti-wear washer 13 can prevent the nut end of the fixing bolt 4 from directly contacting the first connecting block 2 and causing wear to the first connecting block 2 when rotating.

[0040] Reference Figure 3 The side wall of the limiting plate 9 away from the limiting rod 8 has a connecting groove 14 for connecting with an external drive device. The connecting groove 14 facilitates the connection of the external drive device with the limiting plate 9 and allows for quick rotation of the fixing bolt 4.

[0041] Reference Figure 1 One side wall of the arc-shaped mold plate 1 is coated with an anti-adhesion agent 15. The anti-adhesion agent 15 can effectively prevent the concrete component from sticking to the mold tube, making demolding easier.

[0042] The implementation principle of this application is as follows: In use, the user first inserts all four arc-shaped mold plates 1 into the annular groove 11, quickly aligns each arc-shaped mold plate 1 to form a mold tube, aligns the first connecting block 2 and the second connecting block 3 with each other, then passes the fixing bolt 4 through the first connecting block 2 and the second connecting block 3, and makes the fixing bolt 4 threadedly connected to the fixing sleeve 5, connecting and fixing the four arc-shaped mold plates 1 with each other to form a mold tube. At the same time, the arc-shaped holes 6 are aligned with each other to form through holes. Then, the reinforcing bars are inserted into the through holes respectively, and then the concrete component is poured. After waiting for the concrete to set, the fixing bolt 4 is removed, the four arc-shaped mold plates 1 are separated, the mold tube is disassembled, and the concrete component is taken out. At the same time, during demolding, the fixing bolt 4 can be moved into the U-shaped frame 7 by the limiting rod 8 and the limiting plate 9 to prevent the fixing bolt 4 from falling off and to avoid loss of the fixing bolt 4, which would cause resource waste. This avoids the problem of having to take it out of the mold when the concrete has initially set, then inserting the reinforcing bars and waiting for final setting, which can easily cause the concrete component to deform and become unusable, resulting in resource waste.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
