Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a prefabricated composite floor slab stacking and alignment device. Background Art

[0002] Composite floor is a kind of building formwork that combines prefabricated and cast-in-place concrete. Composite floor is an assembled integral floor made of prefabricated panels and cast-in-place reinforced concrete layers. Composite floor has good integrity, and the upper and lower surfaces of the board are flat, which is convenient for finishing layer decoration. It is suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity. Before construction, in order to save space, composite floor is generally stacked together layer by layer.

[0003] However, the existing composite floor slabs are relatively complicated to stack. Generally, the composite floor slabs are transported by crane and aligned by manpower before stacking to prevent tilting or even collapse caused by misalignment between the floor slabs. In addition, each stacked layer of composite floor slabs needs to be laid with another layer of sleepers to properly buffer the pressure to prevent collisions and damages between the floor slabs. The stacking efficiency is relatively low and it is very labor-intensive and resource-intensive.

[0004] Based on the above situation, the utility model proposes a fast stacking prefabricated composite floor slab stacking and alignment device. Utility Model Content

[0005] In order to overcome the shortcomings of existing composite floor slabs that require cumbersome operations such as manual adjustment and alignment and manual laying of sleepers during stacking, resulting in low overall stacking efficiency, the utility model provides a fast-stacking prefabricated composite floor slab stacking and alignment device.

[0006] A prefabricated composite floor slab stacking and alignment device comprises a base plate, a limit frame, a floor slab, a support plate, a torsion spring, a connecting rope, a rotating shaft and a limit mechanism, wherein the base plate is fixedly connected to the limit frame, the limit frame is slidably connected to the floor slab, the limit frame is rotatably connected to pairs of longitudinally distributed rotating shafts, pairs of torsion springs are fixedly connected between the rotating shafts and the limit frame, the rotating shafts are fixedly connected to the support plate, the floor slab and the support plate are squeezed together, connecting ropes are fixedly connected between adjacent rotating shafts, and the limit frame is provided with a limit mechanism.

[0007] In addition, it is particularly preferred that the limiting mechanism includes a blocking frame and a baffle, the limiting frame is fixedly connected with a pair of blocking frames, the blocking frames are in contact and cooperation with the support plates, and the limiting frame is fixedly connected with a pair of longitudinally distributed baffles, the baffles are in contact and cooperation with the support plates.

[0008] In addition, it is particularly preferred that it also includes a rotating plate, a connecting column, a motor and a pulley assembly, wherein the pulley assembly includes two pulleys and a belt, and the belt is wound between the two pulleys, the limit frame is fixedly connected to a pair of motors, the output end of the motor is fixedly connected to a pulley in the pulley assembly, the limit frame is fixedly connected to a pair of connecting columns, the paired connecting columns are rotatably connected with a rotating plate, and the rotating plate is fixedly connected to the other pulley in the paired pulley assembly.

[0009] In addition, it is particularly preferred that it also includes a limit plate, a cylinder, a connecting inclined plate and a roller group, the limit frame is fixedly connected with a pair of longitudinally distributed limit plates, the longitudinally distributed limit plates are slidably connected with connecting inclined plates, the limit frame is fixedly connected with a pair of cylinders, the cylinder output end is fixedly connected to the adjacent connecting inclined plate, and the connecting inclined plate is rotatably connected with the roller group.

[0010] In addition, it is particularly preferred that the support plate is made of metal and a rubber pad is fixed to the surface.

[0011] In addition, it is particularly preferred that the rotating plate is made of rubber and has a certain elasticity.

[0012] Compared with the prior art, the utility model has the following advantages: 1. The utility model can rotate the two upper support plates while stacking each layer of composite floor slabs through supporting plates, connecting ropes and other components, so as to provide buffer support for the next composite floor slab, while ensuring the stacking and alignment of the composite floor slabs, avoiding the need to manually lay sleepers layer by layer, thereby improving the stacking efficiency of the prefabricated composite floor slab stacking and alignment device.

[0013] 2. The utility model can take moisture-proof and sun-proof measures for the composite floor slabs after stacking through components such as rotating plates and motors, thereby preventing the composite floor slabs from being damaged by wind and rain during long-term stacking, thereby improving the protective effect of the prefabricated composite floor slab stacking and alignment device.

[0014] 3. The utility model can conveniently switch between stacking and transportation modes through components such as cylinders and roller groups. When stacking, it can be attached and fixed on the ground, and when transporting, the roller group can be extended for easy movement, thereby improving the practicality of the prefabricated composite floor stacking and alignment device.

DETAILED DESCRIPTION

[0025] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0026] Example 1

[0027] A prefabricated composite floor slab stacking and alignment device, such as Figure 1-Figure 5As shown, it includes a base plate 1, a limit frame 2, a floor slab 3, a support plate 5, a torsion spring 7, a connecting rope 8, a rotating shaft 9 and a limit mechanism. The top of the base plate 1 is fixedly connected to the limit frame 2, the floor slab 3 is slidably connected inside the limit frame 2, the front and rear sides of the limit frame 2 are rotatably connected to the rotating shafts 9 distributed vertically up and down, a pair of torsion springs 7 are fixedly connected between the rotating shafts 9 and the limit frame 2, the outside of the rotating shaft 9 is fixedly connected to the support plate 5, the floor slab 3 and the support plate 5 are squeezed together, connecting ropes 8 are fixedly connected between adjacent rotating shafts 9, and a limit mechanism is provided on the limit frame 2.

[0028] like Figure 3-Figure 5 As shown, the limiting mechanism includes a blocking frame 4 and a baffle 6. The blocking frame 4 is fixedly connected to the front and rear sides of the limiting frame 2, and the blocking frame 4 is in contact with the support plate 5. The baffle 6 distributed vertically up and down is fixedly connected to the front and rear sides of the limiting frame 2, and the baffle 6 is in contact with the support plate 5.

[0029] like Figure 4 As shown, the support plate 5 is made of metal and a rubber pad is fixed on the surface.

[0030] When workers need to align and stack multiple floor slabs 3 together, they first lift the floor slab 3 through an external crane, and then slide the floor slab 3 downward along the slide groove of the limit frame 2. At this time, the two lowest support plates 5 are in a state of 45 degrees upward, and the other support plates 5 are in a state of about 80 degrees upward. The downward sliding of the floor slab 3 will only contact the support plates 5 inclined at 45 degrees upward. After contact, the floor slab 3 will squeeze the support plates 5 and make the support plates 5 and the rotating shaft 9 rotate downward, and the torsion spring 7 will be deformed immediately. However, due to the existence of the blocking frame 4 and the baffle 6, the support plates 5 can only rotate within a certain range. Therefore, the downward rotation of the support plates 5 will eventually only rotate to a horizontal state and the floor slab 3 will be When the first support plate 5 at the bottom rotates downward, the second support plate 5 adjacent to the upper side will be rotated to a state of 45 degrees upward through the tightened connecting rope 8 and the rotating shaft 9. At this time, the connecting rope 8 between the second support plate 5 and the third support plate 5 adjacent to the upper side is also almost straight. Then, when a floor slab 3 is transported and stacked by the crane, the floor slab 3 will contact and squeeze the second support plate 5, so that the second support plate 5 is rotated to a horizontal state, and the third support plate 5 is rotated to a state of 45 degrees upward through the connecting rope 8 and the rotating shaft 9. By analogy, multiple floor slabs 3 are aligned and stacked together, and each adjacent floor slab 3 is supported and separated by a support plate 5.

[0031] Example 2

[0032] On the basis of Example 1, Figure 6 and Figure 7As shown, it also includes a rotating plate 10, a connecting column 11, a motor 12 and a pulley assembly 13, wherein the pulley assembly 13 includes two pulleys and a belt, and a belt is wound between the two pulleys, the front and rear sides of the limit frame 2 are fixedly connected with the motors 12 that are symmetrically distributed on the left and right, the output end of the motor 12 is fixedly connected to a pulley in the pulley assembly 13, the front and rear sides of the limit frame 2 are fixedly connected with the connecting columns 11 that are symmetrically distributed on the left and right, the rotating plate 10 is rotatably connected between the connecting columns 11 on the left and right sides, and the left and right parts of the paired rotating plates 10 that are away from each other are fixedly connected to another pulley in the pulley assembly 13.

[0033] like Figure 6 As shown, the rotating plate 10 is made of rubber and has a certain elasticity.

[0034] When workers need to stack floor slabs 3, they need to start the motor 12 first, and drive the two rotating plates 10 to rotate in a direction away from each other through the pulley assembly 13 to avoid blocking the stacking of the floor slabs 3. After stacking is completed, start the motor 12, and drive the two rotating plates 10 to rotate in a direction close to each other through the pulley assembly 13 until the two rotating plates 10 are close to each other, so as to protect the floor slabs 3 from rain and sun.

[0035] Example 3

[0036] On the basis of Example 2, Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a limit plate 14, a cylinder 15, a connecting inclined plate 16 and a roller group 17. The limit plates 14 that are symmetrically distributed up and down are fixedly connected on both sides of the limit frame 2. The connecting inclined plates 16 are slidably connected between the limit plates 14 that are distributed up and down on the same side. The limit frame 2 is fixedly connected on both sides of the limit frame 2 with cylinders 15 that are symmetrically distributed up and down. The output end of the cylinder 15 is fixedly connected to the adjacent connecting inclined plate 16, and the roller group 17 is rotatably connected to the bottom of the connecting inclined plate 16.

[0037] When workers need to move and transport the stacked floor slabs 3, they can start the cylinder 15 to drive the connecting inclined plate 16 and the roller group 17 to move downward, and lift up the bottom plate 1, the limit frame 2 and the floor slab 3 in cooperation with the ground. At this time, the roller group 17 can be used for convenient transportation. When workers need to fix the stacked floor slabs 3, they can start the cylinder 15 to drive the connecting inclined plate 16 and the roller group 17 to move upward and reset, so that the bottom plate 1 is close to the ground.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
