Description

Technical Field

[0001] The utility model relates to the technical field of floor slabs, in particular to a prefabricated concrete floor slab. Background Art

[0002] Cast-in-place reinforced concrete floor refers to the floor made on site according to the designed position, through formwork support, steel bar binding, concrete pouring, curing and formwork removal. This floor is strong, durable, fireproof and low cost.

[0003] A Chinese patent application CN207878746U discloses a precast concrete floor slab. The key points of its technical solution are: through multiple structural improvements, multiple precast floor slabs are combined into a whole, thereby producing an overall casting effect, so that the integrity and continuity of the floor slab are guaranteed, and it has high stability and seismic strength.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: floor slabs are relatively common building materials in house construction, and most floor slabs are prefabricated. After the floor slabs are produced, they need to be stacked. During the stacking process, in order to facilitate transportation, objects such as wooden blocks are used to separate the space between two floor slabs. Since traditional floor slabs need to be stacked together when stacked, when wooden blocks are used, unstable stacking may occur due to incorrect positioning of the wooden blocks or different heights of the wooden blocks. Therefore, a prefabricated concrete floor slab is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a precast concrete floor slab described in the utility model includes a slab support device, and two support devices are provided on the surface of the slab, and the support device includes a pad, and the pad is located at the bottom end of the slab, and the surface of the pad is rotatably connected to two support rods, and the surfaces of the two support rods are provided with a plurality of limiting grooves, and the inner walls of the limiting grooves of the support rods are inserted with clamping blocks, and the clamping blocks are located on the upper surface of the slab, and the inner walls of the clamping blocks and the support rods are threadedly connected with positioning pins, and the positioning pins are rotated to the inner walls of the clamping blocks and the support rods, and finally the next slab is placed on the upper surface of the clamping blocks. By arranging the pad, the support rods and the clamping blocks, the slab can be supported, and it is convenient for the slab to be taken.

[0007] Preferably, a plurality of positioning holes are opened on the surface of the support rod, and positioning pins are threadedly connected to the inner wall of the clamp block and the inner wall of the positioning hole of the support rod. After the clamp block is attached to the support rod, the positioning pins are rotated to the inner wall of the clamp block and the inner wall of the positioning hole of the support rod, and the positioning pins can fix the position of the clamp block on the surface of the support rod.

[0008] Preferably, the inner walls of the two pads are slidably connected to two sliding rods, and both sides of the two sliding rods are fixedly connected to limiting plates. When the pads slide, they will slide on the surfaces of the sliding rods, and the limiting plates will block the position of the pads. The sliding rods and the limiting plates can limit the moving position of the pads.

[0009] Preferably, a sliding hole is provided on the surface of the pad near the slide rod, and the inner wall of the sliding hole of the pad is slidably connected to the surface of the slide rod. When the pad slides, it slides on the surface of the slide rod through the sliding hole.

[0010] Preferably, a prompt device is provided on the surface of the board body, and the prompt device includes a plug post, and the plug post is inserted into the inner wall of the board body. The side walls of the plug post are fixedly connected with a plurality of anti-slip strips, and the anti-slip strips are inserted into the inner wall of the board body. The surface of the plug post is fixedly connected with a notice board, and information paper is adhered to the surface of the notice board. By setting the notice board, the information paper can be supported and fixed.

[0011] Preferably, a card frame is fixedly connected to the side wall of the notice board, a top block is fixedly connected to the surface of the plug post, and the information paper is inserted into the inner wall of the card frame. The card frame can be provided to facilitate replacement of the information paper.

[0012] The utility model is beneficial in that:

[0013] 1. When the utility model needs to place a plate, the pad is pulled to make it slide on the surface of the slide rod through the sliding hole. The pad will be blocked by the limit plate when sliding. After the pad is moved to a suitable position, the plate is placed on the surface of the pad, and then the support rod is rotated to make the support rod rotate on the surface of the pad. After the support rod is rotated to a suitable angle, the clamping block is inserted into the inner wall of the limiting groove of the support rod, and then the positioning pin is rotated into the positioning holes of the clamping block and the support rod, and then the second plate is placed, and the subsequent plates are placed in this way. By arranging the pad, the support rod, the clamping block and the positioning pin, the plate can be supported and the plate can be placed in a more regular manner, which reduces the tilting of the plate due to various reasons, thereby increasing safety.

[0014] 2. After the same batch of boards are stacked, the utility model aligns the plug posts with the appropriate board, and then pushes the plug posts to drive the anti-slip strips and the signboard to slide. The plug posts and the anti-slip strips will be inserted into the inner wall of the board, and then the information paper will be inserted into the inner wall of the card frame on the signboard. When the plug posts slide, the top block will also slide, and the top block will be against the ground.
