Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a safety protection cover plate for a post-cast zone notch. Background Art
[0002] Post-cast strips are installed in concrete structures, such as the floor slab, walls, and beams. They divide the building structure into multiple sections and eliminate cracks caused by uneven settlement, concrete shrinkage, and other factors. Before concrete is poured, the post-cast strip creates a large gap within the building, up to 0.8 meters wide. This poses a significant risk to workplace safety, and therefore requires covering with materials such as wooden boards. However, simple coverings can easily shift or become lost, leaving the gap in the post-cast strip incompletely protected. Utility Model Content
[0003] The utility model aims to provide a post-cast strip notch safety protection cover plate that can reliably cover the post-cast strip notch, solving the problem of easy dislocation and loss of the existing plate body directly covering the post-cast strip notch, which leads to the post-cast strip notch not being fully protected.
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a safety protection cover plate for the gap of the post-cast strip, comprising a left reinforced concrete plate and a right reinforced concrete plate, the left reinforced concrete plate and the right reinforced concrete plate are disconnected to form a post-cast strip gap, the left reinforced concrete plate and the right reinforced concrete plate are connected together by a plurality of connecting steel bars, and the connecting steel bars are distributed along the length direction of the post-cast strip gap, and the characteristic is that it also includes a plurality of plate pieces distributed along the length direction of the post-cast strip gap and connected to the connecting steel bars through a vertical limiting structure, and two transverse limiting ridges distributed along the width direction of the post-cast strip gap are connected to the lower surface of the plate piece, the transverse limiting ridge on the left side abuts against the left reinforced concrete plate, and the transverse limiting ridge on the right side abuts against the right reinforced concrete plate, and the two sides of the plate piece are respectively supported on the left reinforced concrete plate and the right reinforced concrete plate. When in use, the panels are sequentially placed along the length of the post-cast strip notch and placed over it. The vertical limit structure pulls the panels down so that they are pressed against the left and right reinforced concrete slabs. The horizontal limit ribs position the panels, ensuring they meet the required position and prevent lateral movement. The connection is reliable.
[0005] Preferably, between two adjacent plates, one end of the transverse limiting ridge of one plate extends out and is supported below the other plate, so that the plates support each other to form a whole, thereby improving the load-bearing capacity of the plates.
[0006] Preferably, the vertical limiting structure comprises a hanging hole provided on one end of the plate and a hanging ring suspended in the hanging hole, wherein the hanging ring is sleeved on the connecting steel bar, thereby achieving a simple structure and reliable connection.
[0007] Preferably, the hanging hole is a long hole extending along the length direction of the post-casting strip notch. The position of the hanging ring can be adjusted so that the hanging ring can be accurately hung on the connecting steel bar.
[0008] Preferably, the hanging ring is an openable structure, which makes it convenient to connect and remove the hanging ring and the connecting steel bar.
[0009] Preferably, the hanging ring comprises a hanging rod inserted into the hanging hole and a ring body made of an elastic band connected to the lower end of the hanging rod, wherein the upper end of the hanging rod is provided with an upper hanging block hooked on the upper surface of the plate, and the lower end is provided with a lower hanging block, and both ends of the elastic band are provided with connecting holes, and the hanging rod is inserted into the two connecting holes so that the two ends of the elastic band are hung on the lower hanging blocks. When in use, the elastic band is wrapped around to form a ring and sleeved with the connecting steel bar, and then the hanging rod is passed through the connecting hole and the lower hanging block is located below the connecting hole. Under the elastic action of the elastic band, the two ends of the elastic band are separated, so that the lower hanging block will not fall off the lower hanging block.
[0010] Preferably, notches are provided on both sides of the lower end of the suspension rod, with the lower end surfaces of the notches forming the lower suspension block. This allows the lower suspension block to pass through the suspension hole when the width of the suspension hole is comparable to the size of the suspension rod. This reduces the lateral range of movement of the suspension rod within the suspension hole, allowing for more accurate positioning.
[0011] Preferably, the upper hanging block is provided with a threaded through hole, and the upper end of the hanging rod is threadedly connected to the threaded through hole, so that the hanging ring and the connecting steel bar can be directly and firmly tied together, thereby improving the accuracy and reliability of positioning.
[0012] Beneficial effect: the plate can reliably cover the gap of the post-casting strip without shifting or losing, thereby ensuring that the gap of the post-casting strip is reliably and completely protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figures 1 to 3 A post-cast strip gap safety protection cover plate includes a left reinforced concrete slab 1 and a right reinforced concrete slab 2. The left reinforced concrete slab and the right reinforced concrete slab are disconnected to form a post-cast strip gap 3. The left reinforced concrete slab and the right reinforced concrete slab are connected together by a plurality of connecting steel bars 4. The connecting steel bars are distributed along the length direction of the post-cast strip gap. It also includes a plurality of plate pieces 5 spliced together and distributed along the length direction of the post-cast strip gap. The plate pieces are connected to the connecting steel bars through a vertical limiting structure 6. Two transverse limiting ridges 7 distributed along the width direction of the post-cast strip gap are connected to the lower surface of the plate piece. The transverse limiting ridge on the left side abuts against the left reinforced concrete slab, and the transverse limiting ridge on the right side abuts against the right reinforced concrete slab. The two sides of the plate piece are supported on the left reinforced concrete slab and the right reinforced concrete slab respectively.
[0020] Between two adjacent plates, one end of the transverse limiting ridge 8 of one plate extends out and is supported under the other plate 9. The vertical limiting structure includes a hanging hole 10 provided on one end of the plate and a hanging ring 11 suspended in the hanging hole. The hanging ring is sleeved on the connecting steel bar. The hanging hole is a long hole extending along the length direction of the notch of the post-cast strip. The hanging ring is an openable structure. The hanging ring includes a hanging rod 12 passed through the hanging hole and a ring body 18 made of an elastic band connected to the lower end of the hanging rod. The upper end of the hanging rod is provided with an upper hanging block 13 hooked on the upper surface of the plate, and the lower end is provided with a lower hanging block 14. Both ends of the elastic band are provided with connecting holes 15.
