Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building components, in particular to a concrete composite slab. BACKGROUND

[0002] The concrete composite slab is a fabricated floor slab combining the advantages of prefabricated and cast-in-situ concrete, which is usually composed of a prefabricated bottom plate and a post-cast concrete composite layer to form a monolithic load-bearing floor slab structure.

[0003] In the related art, reference can be made to the Chinese Utility Model Patent with the patent number CN210562908U, which discloses a prefabricated reinforced concrete composite slab, belonging to the field of building components. The prefabricated reinforced concrete composite slab comprises a prestressed concrete composite slab, high-strength prestressed steel wires, and transverse perforated steel bars. The high-strength prestressed steel wires are longitudinally embedded in the prestressed concrete composite slab, and the transverse perforated steel bars are transversely penetrated through the convex ribs of the prestressed concrete composite slab. The prestressed concrete composite slab comprises a composite slab splicing male plate and a composite slab splicing female plate. One end of the composite slab splicing male plate and one end of the composite slab splicing female plate are mutually overlapped and spliced.

[0004] When the above-mentioned composite slab is transported and hoisted on site, the lifting hooks or straps are usually directly hung on the edges of the composite slab or the steel bars, which can easily cause damage to the composite slab. However, since the composite slab is a prefabricated component, it is difficult to repair after damage and can only be scrapped, thereby increasing the hoisting difficulty and production cost. UTILITY MODEL CONTENT

[0005] In order to reduce the probability of damage to the plate body during hoisting of the composite slab, the application provides a concrete composite slab.

[0006] The application provides a concrete composite slab, which adopts the following technical scheme:

[0007] A concrete composite slab comprises a plate body and steel bars arranged on the plate body. The plate body is provided with a hoisting device for hanging the strap during hoisting. The hoisting device comprises:

[0008] A lifting ring is horizontally slidably arranged on the plate body. The lifting ring is provided with four lifting rings, which are respectively arranged at the four corners of the plate body.

[0009] A limiting mechanism is arranged on the plate body and used for limiting the position of the lifting ring.

[0010] By adopting the technical scheme, the lifting ring is arranged on the plate body in a sliding mode, the lifting ring can be adapted to the binding straps of different lengths by moving the position of the lifting ring, the position of the lifting ring is limited by the limiting mechanism after the lifting ring is moved to the target position, and then the binding strap is bound on the lifting ring to perform the hoisting work of the plate body, so that the safety and integrity of the plate body in the hoisting process are ensured by the arrangement of the lifting ring, and the convenience of the operator in the hoisting process is greatly improved, so that the hoisting work of the composite board is safer and more efficient.

[0011] Optionally, a horizontal sliding groove is formed in the plate body, one end of the sliding groove is communicated with the outside of the plate body, the lifting ring comprises a base plate and a ring body arranged on the base plate, the base plate is slidingly installed in the sliding groove, and the ring body extends above the plate body.

[0012] By adopting the technical scheme, one end of the sliding groove on the plate body is communicated with the outside of the plate body, the base plate of the lifting ring is moved into the sliding groove when the plate body needs to be hoisted, and the lifting ring can be taken out of the sliding groove after the hoisting is completed, so that the lifting ring does not affect the subsequent concrete pouring work of the plate body, and the lifting ring can be reused, thereby greatly reducing the production cost and resource waste.

[0013] Optionally, the limiting mechanism comprises:

[0014] A limiting plate is arranged on the plate body, the limiting plate is located at the upper opening of the sliding groove and abuts against the surface of the base plate, and a plurality of limiting holes are uniformly formed in the limiting plate along the length direction of the sliding groove;

[0015] A limiting screw is vertically downwardly arranged through the limiting hole and threadedly connected with the threaded hole.

[0016] By adopting the technical scheme, the threaded hole is formed in the base plate, so that after the base plate is moved to the target position, the limiting screw is moved through the limiting hole in the limiting plate and threadedly connected with the threaded hole, so that the base plate can be limited in the sliding groove, and the limiting work is convenient and fast.

[0017] Optionally, the ring body is divided into an installation half ring and a rotating half ring, the installation half ring is arranged on the base plate, the rotating half ring is rotatably installed on the installation half ring, a fixed plate is rotatably arranged on the installation half ring, and the rotating half ring and the installation half ring are closed when the rotating half ring abuts against the fixed plate.

[0018] By adopting the technical scheme, the ring body is divided into the installation half ring and the rotating half ring, the rotating position of the rotating half ring is fixed by the fixed plate, so that the binding strap can be moved into the installation half ring and the rotating half ring by rotating the rotating half ring, and the convenience of binding between the binding strap and the lifting ring is improved.

[0019] Optionally, a rotating mechanism is provided on the substrate, and the mounting half-ring is rotatably mounted on the substrate via the rotating mechanism. The rotating mechanism includes:

[0020] A rotating ring, wherein the rotating ring is disposed on a substrate;

[0021] A rotating shaft is mounted on a mounting half-ring and rotatably passes through the rotating ring.

[0022] A fixing component is disposed on the rotating ring and is used to fix the rotational position of the rotating shaft within the rotating ring.

[0023] By adopting the above technical solution, a rotating ring is set on the substrate, and the mounting half ring is rotatably connected to the rotating ring through a rotating shaft. Then, the rotation position of the mounting half ring is fixed by a fixing component, thereby completing the rotational connection between the ring body and the substrate. This allows the ring body to be rotated into the sliding groove and fit against the substrate surface, facilitating the stacking of multiple plates. When the plates need to be lifted, the ring body can be rotated out, which is convenient and practical.

[0024] Optionally, the fixing component includes:

[0025] A fixed spring block is provided with a radially opening on the outer wall of the rotating shaft, and the fixed spring block is slidably mounted on the moving groove.

[0026] A fixed spring is provided, which is set on the bottom wall of the moving groove and connected to the fixed spring block. Two fixing holes, one vertical and one horizontal, are opened on the outer wall of the rotating ring. Under the action of the fixed spring, the fixed spring block partially protrudes out of the moving groove and is inserted into the fixing hole.

[0027] By adopting the above technical solution, the fixed spring is compressed and moved so that the entire fixed spring enters the moving groove. Then the rotating shaft can be rotated freely to adjust the position of the ring. When the ring rotates to a vertical or horizontal position, the fixed spring partially protrudes from the moving groove under the action of the fixed spring and engages with the fixing hole, thereby fixing the position of the ring.

[0028] Optionally, an arc-shaped guide surface is provided on the end face of the end where the fixing spring block engages with the fixing hole.

[0029] By adopting the above technical solution, an arc-shaped guide surface is opened on the end face of the fixed spring block that is engaged with the fixed hole. After the guide surface contacts the inner wall of the fixed hole, a component force is generated to drive the fixed spring block to move into the moving groove. Therefore, the rotating shaft can be rotated without the operator having to completely move the fixed spring block into the moving groove, making the rotation of the rotating shaft more convenient and efficient.

[0030] To sum up, the present application comprises at least one of the following beneficial technical effects:

[0031] 1. By setting the lifting ring on the plate body through sliding, the lifting ring can be adapted to different lengths of the binding belt by moving the position of the lifting ring. After moving to the target position, the position of the lifting ring is limited by using a limiting mechanism, and then the binding belt is bound on the lifting ring for hoisting work of the plate body. Therefore, the safety and integrity of the plate body during hoisting are ensured by the setting of the lifting ring, and the convenience of the operator during hoisting is greatly improved, so that the hoisting work of the laminated board is safer and more efficient.

[0032] 2. By connecting one end of the sliding groove on the plate body with the outside of the plate body, when hoisting of the plate body is needed, the base plate of the lifting ring is moved into the sliding groove. After hoisting is completed, the lifting ring can be taken out of the sliding groove, so that the lifting ring does not affect the subsequent concrete pouring work of the plate body, and the lifting ring can be reused, greatly reducing the production cost and resource waste.

[0033] 3. By opening an arc-shaped guide surface on the end face of the end of the fixed elastic block and the fixed hole, the guide surface will generate a driving force for the fixed elastic block to move into the moving groove after contacting the inner side wall of the fixed hole, so that the rotating shaft rod can be rotated without the need for the staff to completely move the fixed elastic block into the moving groove, making the rotating work of the rotating shaft rod more convenient and efficient.
