Description

Technical Field

[0001] This application relates to the field of construction, and in particular to an apparatus for producing precast concrete floor slabs. Background Technology

[0002] The floor slabs of lightweight housing structures mainly use precast reinforced concrete floor slabs. These slabs undergo multiple construction processes in the factory, including formwork erection, rebar tying, concrete pouring, curing, and formwork removal, before being transported to the construction site for assembly and construction. This significantly shortens the construction period and reduces project costs. However, when demolding the precast floor slabs after curing, a crane is typically used to lift the concrete slabs from the mold. The crane requires a support frame for installation, and the range of the support frame determines the crane's movement range. Producing large areas of precast concrete floor slabs on open ground necessitates a large support frame, leading to higher production costs. Conversely, if only a small support frame is available, the precast concrete slabs must be transported one by one to the crane for demolding, making demolding inconvenient. Summary of the Invention

[0003] To facilitate the demolding of precast concrete floor slabs, this application provides a precast concrete floor slab production apparatus.

[0004] This application provides a precast concrete floor slab production device, which adopts the following technical solution:

[0005] A precast concrete floor slab production device includes a bottom formwork, support members located at opposite ends of the bottom formwork, and side plates disposed at opposite ends of the bottom formwork, with the two support members and two side plates forming a ring; each support member includes a base plate, a support plate, a vertical plate, and an end plate, the base plate and the support plate being horizontally arranged, the support plate being spaced apart above the base plate, the vertical plate fixing the base plate and the support plate, and the end plate being vertically fixed to the top surface of the support plate, with the end plate and the support plate spaced apart near the edge of the precast concrete floor slab; the end plate, side plates, and bottom formwork form a molding cavity for the precast concrete floor slab;

[0006] The bottom template is located between the base plate and the support plate at both ends, and also includes a lifting member that presses the bottom template against the bottom surface of the support plate. The lifting member includes a lifting column and a lifting sleeve threaded onto the lifting column. The bottom end of the lifting column is fixed to the top surface of the base plate.

[0007] By adopting the above technical solution, during production, the lifting device presses the bottom formwork tightly against the bottom surface of the support plate. The end plates, side plates, and bottom formwork form the molding cavity of the precast concrete floor slab. Concrete is poured into the molding cavity, and after curing, the bottom formwork is lowered and demolded by unscrewing the lifting device. After the side plates are removed, the end plates and the top surface of the support plate are spaced apart near the edge of the precast concrete floor slab, allowing both ends of the precast concrete floor slab to rest on the support plate, with the bottom surface of the precast concrete floor slab suspended in the air. This eliminates the need to lift the precast concrete floor slab for demolding, facilitating large-area precast floor slab production and reducing production costs. Furthermore, during transportation, a forklift is used, with the forks positioned on the bottom surface of the demolded precast concrete floor slab to lift it for transport and loading, making transportation convenient. Simultaneously, because the end plates and the top surface of the support plate are spaced apart near the edge of the precast concrete floor slab, the steel structure end shells are placed on the top surface of the support plate, ensuring that the steel structure is located at the center of the precast concrete floor slab after pouring, facilitating operation.

[0008] Optionally, a wrench plate is provided on the side wall of the lifting sleeve.

[0009] By adopting the above technical solution, it is convenient for workers to manually operate the wrench to rotate the lifting sleeve.

[0010] Optionally, a limiting post is fixed on the top surface of the support plate, the length direction of the limiting post is vertical, and limiting holes are opened at both ends of the side plate for the limiting post to pass through.

[0011] By adopting the above technical solution, the limiting column is set vertically to position the side plate, which facilitates the installation of the side plate.

[0012] Optionally, it also includes auxiliary reinforcing components, which include a main frame and a connecting part disposed on the main frame. The connecting part includes a connecting column disposed on the bottom surface of the main frame. The center of the lifting column is provided with a connecting groove for the connecting column to be inserted. The connecting column is vertical. The main frame is located on the bottom surface of the bottom template and supports the bottom template.

[0013] By adopting the above technical solutions, the auxiliary reinforcing components support the bottom formwork, making it less prone to deformation and extending its service life. The connection mechanism, where the connecting column is inserted into the connecting groove, limits the position of the main frame, preventing it from shifting.

[0014] Optionally, the connecting part further includes a connecting plate and a limiting block. The connecting plate is close to the side wall of the lifting sleeve, and the limiting block is fixed to the side wall of the connecting plate close to the side wall of the lifting sleeve. A limiting ring groove is formed on the side wall of the lifting sleeve for the limiting block to be accommodated. A sliding rod is provided on the side wall of the connecting plate, and a sliding channel for the sliding rod to slide is provided on the main frame. A spring is provided in the sliding channel, and the spring force drives the sliding rod to be located in the sliding channel. At this time, the limiting block is located in the limiting ring groove.

[0015] By adopting the above technical solution, when the bottom formwork is bonded to the precast concrete floor slab, if the auxiliary reinforcement is also bonded to the bottom formwork, the main frame can easily detach from the jacking sleeve after the jacking sleeve is screwed down. The connection plate, limit block and limit ring groove are set to limit the auxiliary reinforcement on the jacking sleeve, thereby improving the connection stability between the auxiliary reinforcement and the jacking sleeve.

[0016] Optionally, a water pipe is provided inside the support member, and a plurality of nozzles are provided on the end plate. The water pipe is connected to the nozzles, and the nozzles are oriented towards the top of the bottom template.

[0017] By adopting the above technical solutions, outdoor maintenance usually requires watering. Setting up sprinklers and water pipes makes it easy to achieve automated watering, reduce manual labor, and make it easy to control the amount of water, resulting in good maintenance effect.

[0018] Optionally, the upright plate is disposed in the middle of the width direction of the top surface of the substrate, and four lifting members are disposed on the substrate, with the four lifting members disposed in pairs on both sides of the upright plate, and the end plate is also disposed in the middle of the width direction of the top surface of the support plate.

[0019] By adopting the above technical solution, it is convenient to fix the bottom formwork on both sides of the support component, so that the produced precast concrete floor slabs are arranged in a row, which facilitates concrete pouring and management. At the same time, there is space between each row for walking, which facilitates forklift movement and thus facilitates transportation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. After the precast concrete floor slab has cured, the bottom formwork is lowered and demolded by unscrewing the top lifting sleeve. After the side plates are removed, the two ends of the precast concrete floor slab are placed on the support plate. Therefore, it is not necessary to lift the precast concrete floor slab for demolding. This facilitates the production of precast floor slabs for large-area laying, and the production cost is low and the transportation is convenient.

[0022] 2. Auxiliary reinforcing components prevent the bottom formwork from deforming, thus extending its service life;

[0023] 3. The design of the connecting plate, limiting block, and limiting ring groove improves the connection stability between the auxiliary reinforcement and the lifting sleeve;

[0024] 4. The installation of nozzles and water pipes facilitates automated water spraying, reduces manual labor, and makes it easy to control the amount of water sprayed. Attached Figure Description

[0036] Reference Figure 2 The lifting sleeve 42 has an integrally formed wrench plate 43 on its side wall. The wrench plate 43 extends along the axial direction of the lifting sleeve 42, making it convenient for workers to operate the lifting sleeve 42 to rotate.

[0037] Reference Figure 2 The substrate 21 is provided with four lifting members 4, which are arranged in pairs on both sides of the upright plate 23.

[0038] Reference Figure 3 , Figure 4 The precast concrete floor slab production device also includes auxiliary reinforcing members 5, which include a main frame 51 and connecting parts 52 disposed on the main frame 51. The main frame 51 is located on the bottom surface of the bottom formwork 1 and supports the bottom formwork 1. The main frame 51 includes two intersecting reinforcing rods 511. Four connecting parts 52 are provided, each corresponding to one end of a reinforcing rod 511.

[0039] Reference Figure 4 Each connecting part 52 is provided in a corresponding manner to the lifting member 4. The connecting part 52 includes a connecting column 521 that fixes the bottom surface of the main frame 51. The center of the lifting column 41 is provided with a connecting groove 411 for the connecting column 521 to be inserted. The connecting column 521 is vertical.

[0040] Reference Figure 4 The connecting part 52 also includes a connecting plate 522 and a limiting block 523. The connecting plate 522 is close to the side wall of the lifting sleeve 42, and the limiting block 523 is fixed to the side wall of the connecting plate 522 close to the side wall of the lifting sleeve 42. A limiting ring groove 421 is provided on the side wall of the lifting sleeve 42, and the limiting ring groove 421 is used to accommodate the limiting block 523.

[0041] Reference Figure 4A sliding rod 53 is fixed to the end of the side wall of the connecting plate 522 near the main frame 51. A sliding channel 54 is provided at the end of the main frame 51 for the sliding rod 53 to slide. A spring 55 is provided in the sliding channel 54.

[0043] Reference Figure 2 A water pipe 7 is embedded in the support member 2, and several nozzles 8 are provided on the end plate 24. The water pipe 7 is connected to the nozzles 8, and the nozzles 8 face upwards towards the bottom template 1. There are two sets of nozzles 8, which face the two ends of the support plate 22 in the width direction and extend upwards at an angle.

[0044] The implementation principle of a precast concrete floor slab production device according to an embodiment of this application is as follows: During production, the lifting component 4 presses the bottom template 1 against the bottom surface of the support plate 22. The end plate 24, the side plate 3 and the bottom template 1 form a molding cavity for the precast concrete floor slab. The steel structure 9 is placed on the support plate 22 at both ends, and the concrete is poured into the molding cavity.

[0045] After the precast concrete slab has cured, the bottom formwork 1 is lowered and demolded by unscrewing the lifting sleeve 42. After the side plates 3 are removed, the end plates 24 and the top surfaces of the support plates 22 are spaced apart near the edges of the precast concrete slab, allowing both ends of the precast concrete slab to rest on the support plates 22. This eliminates the need to lift the precast concrete slab for demolding, facilitating large-area production of precast concrete slabs and reducing production costs. Forklifts are also conveniently used for transporting the precast concrete slabs, making transportation easier.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
