Description

Technical Field

[0001] The present application relates to the technical field of building floors, and particularly to a laminated slab convenient for transportation. Background Art

[0002] A laminated slab, also known as a concrete laminated slab, is a precast and cast concrete slab surface formed by combining a precast slab and cast-in-place steel bars. It is mainly composed of materials such as siliceous mineral fibers, cement, calcareous materials, and adhesives. Due to its high strength, moisture resistance, fire resistance, sound insulation, heat insulation, etc., it has been widely used in building construction. Currently, the common precast laminated slabs are mainly plate bodies cast from concrete materials, with protruding steel bars at the edges of the plate bodies. After mass production in the factory, they can be directly used after being transported to the construction site.

[0003] Chinese Patent No. CN221372619U discloses a concrete combined laminated slab, including a concrete laminated slab. Multiple plate grooves are equidistantly distributed on the surface of the concrete laminated slab. An installation platform is provided between an adjacent group of the plate grooves. Multiple positioning plates are equidistantly arranged on the surface of the installation platform. Grooves are formed on the surface of the positioning plates, and brackets are arranged in the grooves. Multiple positioning rings are equidistantly distributed on the inner wall of the brackets, and steel bars are respectively inserted into the multiple positioning rings.

[0004] During the transportation of the above-mentioned laminated slab, in order to protect the brackets from the weight of the laminated slab above, support blocks usually need to be placed between two adjacent laminated slabs up and down. In order to reduce the sliding between two adjacent laminated slabs during transportation, workers need to fix the support blocks additionally, which will result in an additional workload for the workers and has deficiencies. Utility Model Content

[0005] In order to improve the above problems existing in the transportation of laminated slabs, the present application provides a laminated slab convenient for transportation.

[0006] The laminated slab convenient for transportation provided by the present application adopts the following technical solutions:

[0007] A laminated slab convenient for transportation, including a steel mesh, a steel frame, and a concrete slab. The steel mesh is prefabricated on the concrete slab, the steel frame is arranged on the concrete slab, multiple support seats are arranged on the concrete, and a positioning support assembly is arranged on the support seats. The positioning support assembly is used to support and position other concrete slabs.

[0008] By adopting the above technical solution, the worker hoists the concrete slab onto the transportation equipment through a hoisting machine, and then uses the positioning and supporting assembly to support and position the next concrete slab to be hoisted. This reduces the labor intensity brought by the worker's need to additionally install support blocks, and at the same time reduces the relative sliding of the concrete slab during transportation, reduces the pressure of the weight of the upper concrete slab on the lower steel bar rack, and makes the transportation process more convenient and safe.

[0009] Optionally, a plurality of the support seats are evenly distributed on the concrete slab. The positioning and supporting assembly includes a support rod rotatably arranged on the support seat. A positioning groove for inserting another support rod is formed on the support seat, and a receiving groove for the support rod to rotate is formed on the support seat. A torsion spring is arranged between the support rod and the receiving groove. The rotation directions of two adjacent support rods along the length direction of the concrete slab are opposite, and a control member for controlling the rotation of the support rod is arranged on the support seat.

[0010] By adopting the above technical solution, when the worker needs to hoist the next concrete slab, the worker releases the restriction on the rotation of the support rod through the control member. Under the action of the torsion spring, the support rod rotates, and under the blocking action of the vertical inner side wall of the receiving groove, the support rod is kept vertical. Under the action of the hoisting mechanical equipment, the positioning groove on the support seat of another concrete slab is sleeved on the support rod. Since the rotation directions of the support rods are opposite, the concrete slab located above can be stably fixed.

[0011] Optionally, a lifting ring is rotatably arranged on the support seat. A rotation groove for the lifting ring to rotate is formed on the support seat, and the cross sections of the rotation groove and the lifting ring are both semi-circular.

[0012] By adopting the above technical solution, the worker rotates the lifting ring to make the lifting ring rotate out of the rotation groove, so as to facilitate the hoisting of the concrete slab. Since the position of the lifting ring on the concrete slab is relatively fixed, the worker does not need to adjust the position of hoisting the concrete slab every time, which is convenient for quickly hoisting the concrete slab.

[0013] Optionally, the control member includes a locking rod slidably arranged on the support seat. A pressing groove for the locking rod to slide is formed on the support seat. One end of the locking rod slidably extends into the receiving groove, and the other end slidably extends into the rotation groove. The locking rod in the rotation groove is used to abut against the lifting ring. A locking groove for the locking rod to insert is formed on the support rod. A pressing plate is arranged on the locking rod in the pressing groove, and a compression spring is propped between the pressing plate and the locking groove close to one side of the support rod.

[0014] By adopting the above technical solution, when the worker rotates the lifting ring outside the rotating groove, the end of the locking rod loses the blocking effect of the lifting ring, the compression spring resumes deformation and pushes the pressing plate, and the pressing plate drives the locking rod to slide along the direction away from the support rod until the locking rod disengages from the locking groove on the support rod. At this time, the torsion spring resumes deformation, and under the blocking effect of the vertical side wall of the receiving groove, the torsion spring drives the support rod to turn to the vertical state.

[0015] Optionally, a plurality of fixing plates are arranged on the concrete slab along its length direction. Screws are arranged on the fixing plates. A buckle block is slidably arranged on the screws. The buckle block is used to buckle on the steel bar frame. A toggle bolt is threadedly connected to the screw on the side opposite to the buckle block and away from the fixing plate.

[0016] By adopting the above technical solution, after the worker places the steel bar frame on the fixing plate, the worker turns the toggle bolt to make the buckle block press the steel bar frame on the fixing plate. This operation can quickly fix the steel bar frame, and the operation is simple and convenient.

[0017] Optionally, an adjusting block is slidably arranged on the fixing plate. An adjusting groove for the adjusting block to slide is formed on the fixing plate. The cross sections of the adjusting block and the adjusting groove are both T-shaped. The screw is arranged on the adjusting block. A locking bolt is threadedly connected to the adjusting block. The locking bolt is used to abut against the adjusting groove.

[0018] By adopting the above technical solution, the worker adjusts the position of the adjusting block on the fixing plate through the locking bolt, so that steel bar frames with different widths can be fixed on the fixing plate, reducing the installation difficulty caused by the dimensional deviation of the steel bar frame due to manufacturing errors.

[0019] Optionally, the cross section of the buckle block is C-shaped, and the C-shaped groove of the buckle block buckles on the steel bars of the steel bar frame.

[0020] By adopting the above technical solution, it is convenient to fix the steel bar frame, reducing the possibility of the steel bar frame shifting during the fixing process.

[0021] Optionally, an elastic arc piece is arranged in the receiving groove, and the support rod presses on the elastic arc piece.

[0022] By adopting the above technical solution, after the locking rod disengages from the locking groove of the support rod, the elastic arc piece resumes deformation and supports the support rod, facilitating the support rod to quickly turn to the vertical state.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Workers use hoisting machinery to hoist the concrete slab onto the transportation equipment, and then use the positioning and supporting components to support and position the next concrete slab to be hoisted. This reduces the labor intensity caused by workers having to install additional support blocks, and at the same time reduces the relative sliding of the concrete slab during transportation, reduces the pressure of the weight of the upper concrete slab on the lower steel bar rack, making the transportation process more convenient and safe;

[0025] 2. When workers need to hoist the next concrete slab, they release the restriction on the rotation of the support rod through the control member. Under the action of the torsion spring, the support rod rotates, and under the blocking action of the vertical inner side wall of the receiving groove, the support rod remains vertical. Under the action of the hoisting machinery and equipment, the positioning groove on the support seat of another concrete slab is sleeved on the support rod. Since the rotation directions of the support rods are opposite, the concrete slab located above can be stably fixed;

[0026] 3. When workers rotate the lifting ring out of the rotation groove, the end of the locking rod loses the blocking action of the lifting ring, the compression spring resumes deformation and pushes the pressure plate, and the pressure plate drives the locking rod to slide along the direction away from the support rod until the locking rod disengages from the locking groove on the support rod. At this time, the torsion spring resumes deformation, and under the blocking action of the vertical side wall of the receiving groove, the torsion spring drives the support rod to rotate to the vertical state.

Detailed Embodiments

[0033] The following will further elaborate on this application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0034] An embodiment of this application discloses a laminated slab that is convenient for transportation.

[0035] Referring to Figure 1 , a laminated slab that is convenient for transportation includes a steel bar mesh 1, a steel bar frame 2, and a concrete slab 3. The steel bar mesh 1 is prefabricated on the concrete slab 3, the steel bar frame 2 is arranged on the concrete slab 3, and a plurality of fixing plates 8 are uniformly prefabricated on the concrete slab 3 along its length direction.

[0036] Referring to Figure 1 and Figure 2 , an adjusting block 12 is slidably arranged on the fixing plate 8. The sliding direction of the adjusting block 12 is perpendicular to the arrangement direction of the fixing plates 8. An adjusting groove 13 for the adjusting block 12 to slide is formed on the fixing plate 8. The cross-sections of both the adjusting block 12 and the adjusting groove 13 are T-shaped. A locking bolt 14 is threadedly connected to the adjusting block 12, and the locking bolt 14 is used to press against the inner bottom wall of the adjusting groove 13.

[0037] Referring to Figure 1 and Figure 2 , a vertical screw rod 9 is welded to the adjusting block 12. A buckle block 10 is slidably sleeved on the screw rod 9. The cross-section of the buckle block 10 is C-shaped, and the C-shaped opening of the buckle block 10 faces vertically downward. The C-shaped groove of the buckle block 10 buckles on the steel bars of the steel bar frame 2. A toggle bolt 11 is threadedly connected to the screw rod 9 on the side opposite to the buckle block 10 and away from the fixing plate 8.

[0038] The worker places the steel bar frame 2 on the concrete slab 3, then turns the locking bolt 14. After adjusting the position of the adjusting block 12, turns the toggle bolt 11 to make the C-shaped groove of the buckle block 10 buckle on the steel bars of the steel bar frame 2. Finally, tighten the locking bolt 14 and the toggle bolt 11 to fix the steel bar frame 2 in this way.

[0039] Referring to Figure 1 , Figure 3 and Figure 4 , a plurality of support seats 4 are prefabricated on the concrete. The plurality of support seats 4 are evenly distributed on the concrete slab 3. A lifting ring 6 is rotatably connected to the support seat 4. A rotating groove 7 for the lifting ring 6 to rotate is formed on the support seat 4. The cross-sections of both the rotating groove 7 and the lifting ring 6 are semi-circular. A positioning support assembly 5 is arranged on the support seat 4, and the positioning support assembly 5 is used to support and position other concrete slabs 3.

[0040] Referring to Figure 3 , Figure 4 and Figure 5, the positioning and supporting assembly 5 includes a support rod 51 rotatably connected to the support base 4. A positioning groove 52 for inserting another support rod 51 is formed at the bottom of the support base 4. A receiving groove 53 for the support rod 51 to rotate is formed on the support base 4, and the vertical inner sidewall of the receiving groove 53 is used to abut against the support rod 51.

[0041] Refer to Figure 3 , Figure 4 and Figure 5 , an elastic arc plate 15 is welded in the receiving groove 53. The support rod 51 is used to press on the elastic arc plate 15. A torsion spring 54 is arranged between the rotation center of the support rod 51 and the receiving groove 53. The rotation directions of two adjacent support rods 51 along the length direction of the concrete slab 3 are opposite. A control member 55 for controlling the rotation of the support rod 51 is arranged on the support base 4.

[0042] Refer to Figure 3 , Figure 4 and Figure 5 , the control member 55 includes a locking rod 551 slidably arranged on the support base 4. A pressing groove 552 for the locking rod 551 to slide is formed on the support base 4. One end of the locking rod 551 slidably extends into the receiving groove 53, and the other end slidably extends into the rotation groove 7. The locking rod 551 in the rotation groove 7 is used to abut against the lifting ring 6. A locking groove 553 for the locking rod 551 to insert is formed on the support rod 51. A pressing plate 554 is welded on the locking rod 551 in the pressing groove 552. A compression spring 555 is propped between the pressing plate 554 and the locking groove 553 on the side close to the support rod 51.

[0043] When the worker needs to lift the concrete slab 3, the worker rotates the lifting ring 6 to make the arc part of the lifting ring 6 rotate out of the rotation groove 7. During this process, the end of the locking rod 551 abuts tightly against the lifting ring 6 until the end of the locking rod 551 separates from the lifting ring 6. At this time, the end of the locking rod 551 loses the blocking effect of the lifting ring 6. The compression spring 555 restores its deformation and pushes the pressing plate 554. The pressing plate 554 drives the locking rod 551 to slide along the direction away from the support rod 51 until the locking rod 551 completely disengages from the locking groove 553 on the support rod 51. At this time, the elastic arc plate 15 restores its deformation and props against the support rod 51, and at the same time the torsion spring 54 restores its deformation.

[0044] Under the blocking effect of the vertical inner sidewall of the receiving groove 53, the torsion spring 54 drives the support rod 51 to rotate to a vertical state. Then the worker hangs the hook cable on the lifting equipment on the lifting ring 6 to realize the lifting and transfer of the concrete slab 3 until the positioning groove 52 on the upper concrete slab 3 sleeves on the support rod 51 below. Since the rotation directions of the support rods 51 of the lower concrete slab 3 are opposite, the upper concrete slab 3 can be stably fixed, facilitating the relatively stable maintenance of the stacked concrete slabs 3 on the transport vehicle.

[0045] The implementation principle of a laminated slab convenient for transportation in an embodiment of the present application is as follows: Workers place the steel bar frame 2 on the concrete slab 3, then turn the locking bolt 14. After adjusting the position of the adjusting block 12, turn the toggle bolt 11 to make the C-shaped groove of the buckle block 10 buckle on the steel bars of the steel bar frame 2. Finally, tighten the locking bolt 14 and the toggle bolt 11 to fix the steel bar frame 2 accordingly.

[0046] When workers need to hoist the concrete slab 3, the workers rotate the lifting ring 6 to make the arc part of the lifting ring 6 rotate out of the rotating groove 7. During this process, the end of the locking rod 551 abuts against the lifting ring 6 until the end of the locking rod 551 separates from the lifting ring 6. At this time, the end of the locking rod 551 loses the blocking effect of the lifting ring 6, the compression spring 555 resumes deformation and pushes the pressing plate 554, and the pressing plate 554 drives the locking rod 551 to slide along the direction away from the support rod 51 until the locking rod 551 completely disengages from the locking groove 553 on the support rod 51. At this time, the elastic arc piece 15 resumes deformation and proppingly supports the support rod 51, and at the same time, the torsion spring 54 resumes deformation.

[0047] Under the blocking effect of the vertical inner side wall of the receiving groove 53, the torsion spring 54 drives the support rod 51 to turn to a vertical state. Then the workers hang the hook cable on the lifting equipment on the lifting ring 6 to achieve the hoisting and transportation of the concrete slab 3 until the positioning groove 52 on the upper concrete slab 3 sleeves on the support rod 51 below. Since the rotation directions of the support rods 51 of the lower concrete slab 3 are opposite, the upper concrete slab 3 can be stably fixed, facilitating the relatively stable maintenance of the stacked concrete slabs 3 on the transport vehicle.

[0048] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
