Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a floor slab support device. Background Technology

[0002] Floor slab support devices are an indispensable part of building construction. They are mainly used to provide necessary support and stability during the pouring of floor slab concrete, ensuring the safety and quality of the floor slab structure.

[0003] In related technologies, during the construction of floor slabs, support seats and support columns are required to support the floor slabs. However, the support seats and support columns occupy a large amount of space under the floor slabs, which needs to be improved. Summary of the Invention

[0004] To increase the space under the floor slab, this application provides a floor slab support device.

[0005] A floor slab support device includes a side plate and a support plate slidably connected to the side plate. The side plate is used to abut against the side wall of a wall panel, and the support plate is used to abut against the upper wall of the wall panel. The support plate is used to support a precast floor slab. A limiting plate is provided on the side plate. The limiting plate is spliced ​​with the side plate at a right angle. The limiting plate and the side plate are used to abut against the precast floor slab.

[0006] By adopting the above technical solution, during construction, the floor slab support device is installed above the wall panel. The side panels on both sides are attached to and fixed to the outer walls of the two opposing wall panels. The precast floor slab is placed above the support plate, and the support plate is moved to move the precast floor slab towards the limiting plate. After the precast floor slab is lowered, the support plate is moved to the side of the precast floor slab away from the limiting plate, and the side wall of the support plate abuts against the precast floor slab, so that the side wall of the precast floor slab is in contact with the side panel and the limiting plate. The above steps are repeated to lay several precast floor slabs horizontally above the wall panel. Supporting the floor slab with the wall panel helps to reduce the space occupied under the floor slab and increase the reserved space under the floor slab. By using the limiting plate and side panel to fit the precast floor slab, the precast floor slab is limited, which helps to improve the horizontality and verticality of the laid precast floor slab on the horizontal plane.

[0007] Preferably, it also includes a cable net, which is connected to the limiting plate and the supporting plate respectively, and the cable net is used to cover the precast floor slab.

[0008] By adopting the above technical solution, during actual construction, the movement of the support plate during the laying of the precast floor slab causes the cable net to move to the top of the laid precast floor slab, which facilitates fixing the protrusion on the top of the precast floor slab to the cable net after the precast floor slab is laid.

[0009] Preferably, the side plate is provided with a support frame, which is used to support the cable net and is located above the support plate.

[0010] By adopting the above technical solution, during the laying of precast floor slabs, the precast floor slabs drive the cable net to gradually unfold. The cable net is supported by the support frame, so that the cable net is set at a distance from the precast floor slab during the unfolding process, reducing the occurrence of the cable net driving the precast floor slab to move. After the precast floor slabs are laid, the cable net is lowered and fixed to the precast floor slabs.

[0011] Preferably, the support frame is slidably connected to the side plate, and the side plate is provided with a drive assembly that drives the support frame to move up and down.

[0012] By adopting the above technical solution, in the actual construction process, after the precast floor slabs are laid using the support plate, the drive component drives the support plate to descend, which makes it easier for construction workers to connect several precast floor slabs with the cable net. After the connection is completed, the drive component drives the lifting frame to rise. The lifting frame tightens several precast floor slabs through the cable net, so that the precast floor slabs have a tendency to move and rise, making it less likely for the part between the two side wall panels of the precast floor slabs to bend when the precast floor slabs are subjected to load.

[0013] Preferably, the driving assembly includes a driving frame slidably connected to the side plate and a top rod disposed on the driving frame. The driving frame is located on the moving path of the support plate. The support frame is provided with a guide surface, which is inclined upward in the direction close to the limiting plate. The guide surface is used to abut against the top rod. The support frame is provided with a first support surface, and the top rod is provided with a second support surface. The first support surface is located on the side of the guide surface away from the limiting plate, and the first support surface is used to abut against the second support surface.

[0014] By adopting the above technical solution, during the laying of precast floor slabs, support surface one abuts against support surface two, so that the support frame is above the precast floor slab. After the precast floor slab is laid, the drive frame is moved towards the limiting plate, so that the top rod is disengaged from the support frame, and the support frame descends to bring the cable net down and lay it on the precast floor slab. After the workers fix the cable net and the precast floor slab, the drive frame is moved away from the limiting plate, and the top rod presses against the guide surface, so that the support frame rises along the inclined direction of the guide surface until support surface one and support surface two are in contact, the lifting frame and the drive frame are positioned, and the drive component does not need to be connected to a power source, which helps to reduce energy consumption during construction.

[0015] Preferably, a positioning rod is provided through the side plate, a positioning hole one is provided on the side plate, and a positioning hole two is provided on the drive frame. When the support surface one abuts against the support surface two, the positioning hole one and the positioning hole two are connected, and the positioning rod is positioned by passing through the positioning hole one and the positioning hole two.

[0016] By adopting the above technical solution, when transporting the side panel, the moving drive frame makes the support surface one and the support surface two abut together, and the positioning rod passes through the positioning hole one and the positioning hole two to position the drive frame. This makes it difficult for the support surface two to detach from the support surface one during transportation and laying of the precast floor slab, which facilitates the positioning of the drive frame and the support frame.

[0017] Preferably, the support frame includes a lifting seat that is slidably connected to the side plate and a hook that is slidably connected to the lifting seat. The hook is connected to the cable net. The lifting seat is provided with an elastic element, which abuts against the hook to make the hook have a tendency to move upward.

[0018] By adopting the above technical solution, after the cable net and the precast floor slab are fixed, the lifting seat rises and tightens the precast floor slab, giving the precast floor slab a tendency to move and rise. The elastic element presses against the hook, allowing the hook to move relative to the lifting rod, which helps to prevent the support frame from breaking due to excessive tension.

[0019] Preferably, the support plate is rotatably connected to the side plate, and a plurality of support wheels are rotatably connected to the support plate. The rotation axis of the support wheels is parallel to the length of the support plate, and the support plate is supported on the wall panel by the support wheels.

[0020] By adopting the above technical solution, during construction, the precast floor slab is placed on the support plate. By setting up support wheel one, it is easier to move the support rod, which in turn makes it easier to move the precast floor slab. By setting up support wheel one, the height of the support plate is raised, which makes it easier to rotate the support plate to lower the precast floor slab.

[0021] Preferably, a plurality of support wheels are rotatably connected to the support plate, and the support plate supports the precast floor slab through the support wheels.

[0022] By adopting the above technical solution, the precast floor slab is supported by the second support wheel, which helps to reduce the friction between the precast floor slab and the support plate, making it easier to lower the precast floor slab from the support frame.

[0023] Preferably, the support plate is provided with bristles, which abut against the wall panel.

[0024] By adopting the above technical solution, during the process of laying precast floor slabs with the moving support plate, the support plate drives the brush to move and clean the upper part of the wall panel, which helps to reduce the dust between the precast floor slab and the wall panel after the precast floor slab is laid.

[0025] In summary, this application includes at least one of the following technical effects: 1. Supporting the floor slab with wall panels helps reduce the space occupied beneath the floor slab and increases the reserved space underneath. Using limiting plates and side plates to adhere to the precast floor slab helps to limit its movement, improving the horizontal and vertical accuracy of the laid precast floor slab. 2. The support frame is raised and lowered by the drive component, which makes it easy for construction workers to connect several precast floor slabs with the cable net; and makes the part between the two side wall panels of the precast floor slab less likely to bend when the precast floor slab is under load. 3. By setting support surface one, support surface two, and guide surface, the drive component does not need to be connected to a power source when driving the support frame to rise and fall, which helps to reduce energy consumption during construction.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a floor slab support device. (Refer to...) Figure 1 and Figure 2A floor slab support device includes a side plate 1, a support plate 2, and a cable net 3. The side plate 1 is located on opposite sides of the support plate 2. The length direction of the support plate 2 is parallel to the distribution direction of the side plate 1. The side plate 1 is used to abut against the side wall of the wall panel. The support plate 2 is supported above the wall panel and is used to support the precast floor slab. The side plate 1 has a sliding opening 11. The opposite ends of the support plate 2 pass through the sliding opening 11 and slide to connect with the side plate 1. The support plate 2 is slidably connected to the side plate 1. The rotation axis of the support plate 2 is parallel to the distribution direction of the side plate 1. The support plate 2 is threaded with a limiting nut 21. The position and number of the limiting nuts 21 correspond one-to-one with the position and number of the side plates 1. The limiting nut 21 is located on the side of the corresponding side plate 1 away from the other side plate 1. The limiting nut 21 fits against the side plate 1 and limits the support plate 2.

[0033] Reference Figure 2 A limiting plate 12 is fixed on the side plate 1. The limiting plate 12 is located at one end of the two side plates 1. The length direction of the limiting plate 12 is parallel to the length direction of the support plate 2. The limiting plate 12 is located on one side of the support plate 2 and on the moving path of the support plate 2. The end face of the limiting plate 12 near the support plate 2 is flat. The limiting plate 12 and the two side plates 1 are spliced ​​to form a right angle. The limiting plate 12 and the side plate 1 are used to abut against the precast floor slab and limit the precast floor slab to ensure the horizontality and verticality of the precast floor slab on the horizontal plane.

[0034] During construction, fix the side panel 1 to the ends of the two wall panels that are far apart from each other. Move the precast floor slab close to the limiting plate 12 via the support plate 2. After moving it to the designated position, rotate the support plate 2 so that it tilts downward toward the limiting plate 12. Then move it away from the limiting plate 12 and place the precast floor slab on the wall. At this time, the precast floor slab is located on the moving path of the support plate 2. Move the support plate 2 toward the precast floor slab so that the support plate 2 presses against the precast floor slab so that the precast floor slab presses against the limiting plate 12. The precast floor slab fits against the side panel 1. Repeat the above operation to lay several precast floor slabs on the wall panels in sequence.

[0035] Reference Figure 2 The cable net 3 is fixedly connected to the limiting plate 12 and the support plate 2 at opposite ends. The support plate 2 moves away from the limiting plate 12, causing the cable net 3 to unfold and cover the precast floor slab. A support frame 4 is slidably connected to the side plate 1. The support frame 4 is located above the support plate 2 and on opposite sides of the cable net 3. The support frame 4 is used to support the cable net 3. The support frame 4 moves the cable net 3 closer to or away from the precast floor slab. The cable net 3 has a connection port 31. The position and number of connection ports 31 correspond one-to-one with the position and number of support frames 4. The connection port 31 is elongated. The support frame 4 extends into the connection port 31 and connects with the cable net 3. As the cable net 3 unfolds, the support frame 4 slides and connects with the cable net 3.

[0036] Reference Figure 3 The support plate 2 is rotatably connected to several support wheels 22 and 23. Support wheels 22 are located on the side of the support plate 2 closest to the wall, supporting the support plate 2 against the wall. Support wheels 23 are located on the side of the support plate 2 furthest from the wall, supporting the precast floor slabs. The rotation axes of support wheels 22 and 23 are parallel, and parallel to the distribution direction of the side plate 1. This makes moving the support plate 2 and lowering the precast floor slabs easier.

[0037] Reference Figure 1 Several bristles 24 are fixed on the support plate 2. The vertical projection of the bristles 24 is located on the wall panel. The brush plate abuts against the wall panel to clean the upper part of the wall panel.

[0038] Reference Figure 3 and Figure 4 The support frame 4 includes a lifting seat 41 and several hooks 42. The length direction of the lifting seat 41 is parallel to the sliding direction of the support plate 2. The lifting seat 41 is slidably connected to the side plate 1. A drive assembly 5 is installed on the side plate 1, and the drive assembly 5 drives the lifting rod to rise and fall. Several hooks 42 are all located above the drive rod. The hooks 42 are evenly distributed at equal intervals along the anti-slip direction parallel to the support plate 2. The length direction of the hooks 42 is parallel to the length direction of the support plate 2. The end of the hook 42 away from the lifting rod extends between the two side plates 1. The hooks 42 are used to engage with the connecting port 31 to support the cable net 3. Several hooks 42 are slidably connected to the lifting rod. The lifting base 41 has several lifting slots 411, the position and number of which correspond one-to-one with the position and number of hooks 42. The hooks 42 slide into or out of their corresponding lifting slots 411. Several elastic elements 412 are fixed on the lifting base 41, the position and number of which correspond one-to-one with the position and number of lifting slots 411 and hooks 42. The elastic elements 412 are located below their corresponding hooks 42, and their opposite ends are fixedly connected to the lifting rod and the hook 42, respectively. The elastic elements 412 press against their corresponding hooks 42, causing the hooks 42 to tend to move upwards and extend out of their corresponding lifting slots 411. In this embodiment, the elastic element 412 is a spring.

[0039] Reference Figure 4The drive assembly 5 is located below the lifting seat 41. The drive assembly 5 includes a drive frame 51 and a push rod 52. The drive frame 51 is slidably connected to the side plate 1, and the sliding direction of the drive frame 51 is parallel to the sliding direction of the support plate 2. One end of the drive frame 51 away from the limiting plate 12 protrudes to form a protrusion. The protrusion at the drive frame 51 is located on the moving path of the support plate 2, and the support plate 2 abuts against the protrusion, driving the drive frame 51 to move. The push rod 52 is located above the drive frame 51 and below the lifting seat 41. The push rod 52 is fixedly connected to the drive frame 51. The movement of the drive frame 51 causes the push rod 52 to move into or out of the moving path of the lifting seat 41. The top rod 52 has a support surface 2 521 machined on the side near the lifting seat 41. The lifting frame has a guide surface 413 and a support surface 1 414 machined on the end near the top rod 52. The support surface 1 414 and the support surface 2 521 are flat. The guide surface 413 is inclined and tilted downward in the direction away from the limiting plate 12. The support surface 2 521 is located on the side of the guide surface 413 away from the limiting plate 12. Both the guide surface 413 and the support surface 2 521 are used to abut against the top rod 52. The support surface 2 521 is used to fit against the support surface 1 414.

[0040] Reference Figure 3 and Figure 4 The side plate 1 has a positioning hole 13 and the drive frame 51 has a positioning hole 511. The extension directions of the positioning hole 13 and the positioning hole 511 are parallel to the distribution direction of the side plate 1. When the support surface 1 414 is in contact with the support surface 2 521, the positioning hole 13 and the positioning hole 2 511 are connected. The side plate 1 is provided with a positioning rod 14. The positioning rod 14 passes through the positioning hole 13 and the positioning hole 2 511 in sequence. The positioning rod 14 is in contact with the inner wall of the positioning hole 13 and the positioning hole 2 511 to position the drive frame 51.

[0041] During the transportation and laying of precast floor slabs, the support frame 4 is positioned above the precast floor slabs, thus allowing the cable net 3 to be spaced apart from the precast floor slabs. After laying, the positioning rod 14 is removed, and the drive frame 51 is moved towards the limiting plate 12, causing the drive frame 51 to move away from the limiting plate 12, causing the top rod 52 to disengage from the lifting frame. The lifting frame falls under its own weight, laying the cable net 3 on top of several precast floor slabs. The cable net 3 is then fixed to several precast floor slabs with wire. After the cable net 3 is fixed to the precast floor slabs, it is moved away from the limiting plate 12. The support plate 2 moves in the direction of the position plate 12, causing the support plate 2 to abut against the protrusion of the drive frame 51, driving the drive frame 51 to move away from the limit plate 12. The top rod 52 abuts against the guide surface 413, causing the lifting frame to move and rise along the inclined direction of the guide surface 413. When the lifting frame is above the top rod 52, the first support surface 414 fits against the second support surface 521, and the drive frame 51 supports the support frame 4, so that the part of the precast floor slab located between the wall panels is subjected to an upward force. When the floor slab is under load, the part of the precast floor slab located between the wall panels is not easily deformed.

[0042] Filling the top of the precast floor slab with concrete to form a whole with the cast-in-place concrete part helps to improve the load-bearing capacity of the floor slab.

[0043] The implementation principle of a floor slab support device in this application embodiment is as follows: In the actual construction process, the side plate 1 is fixed to the wall panel, and then the precast floor slab above the wall panel is laid flat by the support plate 2. The support plate 2 is supported by the wall panel, which reduces the floor slab's occupancy rate on the next floor and helps to increase the usable space below the floor slab.

[0044] 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.
