Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically, it relates to a device for preventing the collapse of a composite slab stacking frame. Background Technology

[0002] In construction engineering, precast composite slabs are a commonly used building component, with advantages such as fast construction speed and stable quality.

[0003] At construction sites, composite slabs are typically stacked in a centralized manner. However, existing methods mostly involve simply piling the slabs together with only a few supporting structures. This method presents numerous safety hazards. Firstly, due to the significant weight of the composite slabs and their high center of gravity after stacking, they are highly susceptible to collapse when subjected to external impacts, uneven ground, or stress changes caused by prolonged stacking. This not only damages the slabs and causes economic losses but also poses a serious threat to the lives of nearby construction workers. Secondly, existing supporting structures have poor stability and cannot effectively distribute the weight of the composite slabs, resulting in uneven stress distribution among the slabs and further increasing the risk of collapse.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a composite plate stacking anti-collapse frame device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A composite slab stacking anti-collapse frame device includes: uprights, each upright being a rectangular steel pipe with a base welded to its bottom. The base has multiple mounting holes for fixing the upright to the ground using anchor bolts. The multiple uprights are evenly distributed along the length and width of the composite slab stacking area to form a rectangular frame structure; and multiple crossbeams, with adjacent uprights connected by multiple crossbeams. The multiple crossbeams include upper crossbeams and lower crossbeams, which are respectively welded to the upper and lower parts of the uprights.

[0008] Optionally, two baffles are connected between the upper and lower crossbeams connecting the columns on the left and right sides, and the upper and lower crossbeams are provided with sliding grooves on their opposite surfaces. The upper and lower ends of the baffles are connected to the sliding grooves by sliders.

[0009] Optionally, a limiting hole is provided on the surface of the lower crossbeam connecting the columns on the left and right sides, and the baffle is connected to the lower crossbeam through the limiting hole and the limiting column.

[0010] Optionally, four limiting holes are provided and are evenly distributed, with the limiting holes on the left and right sides close to the side wall of the column.

[0011] Optionally, connecting blocks are provided at the angles between the columns on the front and rear sides and the upper and lower crossbeams they are connected to, and the connecting blocks are triangular in shape.

[0012] Optionally, the connecting blocks at opposite corners are connected by support beams, and the two support beams are arranged in a cross shape.

[0013] Optionally, the upper crossbeam sidewalls connecting the front and rear columns are each connected to a fixing plate, and the other end of the fixing plate is connected to a threaded rod, which passes through the upper crossbeam and is threadedly connected to it.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up columns, the rigid frame structure is fixed with anchor bolts, which can resist the gravity and lateral force generated by the stacking of composite slabs and prevent the frame from collapsing. The adjustable baffle and limit hole design effectively prevents the composite slabs from sliding sideways. The cross support beams and triangular connecting blocks enhance the frame's anti-torsion and anti-lateral displacement capabilities, cope with complex load conditions, and comprehensively ensure the safety of the construction site.

[0016] 2. By setting multiple crossbeams, a rectangular frame and multi-layer crossbeam design, the layout can be adjusted according to the size and quantity of the composite slab, adapting to the stacking of composite slabs of different specifications. The position of the baffle is adjustable and the screw pressure can be flexibly controlled to meet diverse construction needs and improve the versatility of the device.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a composite slab stacking anti-collapse frame device, including: a column 1, which is a rectangular steel pipe with a base 2 welded to its bottom. The base 2 has multiple mounting holes for fixing the column 1 to the ground with anchor bolts. The multiple columns 1 are evenly distributed along the length and width of the composite slab stacking area to form a rectangular frame structure; and multiple crossbeams, which connect adjacent columns 1. The multiple crossbeams include an upper crossbeam 4 and a lower crossbeam 3, which are welded to the upper and lower parts of the column 1, respectively.

[0028] The uprights 1 are made of rectangular steel pipes, possessing high compressive strength and stability, effectively bearing the vertical load and lateral pressure during the stacking of composite slabs. A base 2 is welded to the bottom of upright 1, with multiple mounting holes on the base 2. Anchor bolts pass through these holes and are anchored to the concrete foundation, achieving a rigid connection between upright 1 and the ground, preventing the entire frame from overturning. Multiple uprights 1 are evenly distributed along the length and width of the composite slab stacking area, forming a rectangular frame structure. This layout ensures the load is evenly distributed to the ground, avoiding excessive local stress. The upper and lower horizontal beams 3 form a rigid frame with the uprights 1, enhancing the frame's resistance to lateral displacement in the horizontal direction while limiting the buckling deformation of the uprights 1, ensuring the frame's stability. The overall stability of the rectangular frame structure is ensured by the rigid connection between the columns 1 and the beams, forming a stable mechanical system that effectively resists the horizontal thrust and vertical gravity generated during the stacking of composite slabs. This prevents the frame from tilting or collapsing due to uneven stress. The evenly distributed columns 1 and beams distribute the load and reduce the stress risk of individual components. This design is particularly suitable for stacking large-sized, heavy-load composite slabs. The rectangular frame structure clearly defines the stacking boundaries of the composite slabs, facilitating on-site material management and avoiding safety hazards caused by haphazard stacking. The multi-layer beam design can be combined with horizontal supports or partitions to achieve layered stacking of composite slabs, increasing the stacking capacity within a limited space and improving site utilization.

[0029] In this embodiment, two baffles 6 are connected between the upper beam 4 and the lower beam 3 connecting the columns 1 on the left and right sides. The upper beam 4 and the lower beam 3 have grooves 5 on their opposite surfaces. The upper and lower ends of the baffles 6 are connected to the grooves 5 by sliders. Limiting holes 8 are opened on the surface of the lower beam 3 connecting the columns 1 on the left and right sides. The baffles 6 are connected to the lower beam 3 through the limiting holes 8 and the limiting posts 7. There are four limiting holes 8, which are evenly distributed. The limiting holes 8 on the left and right sides are close to the side walls of the columns 1.

[0030] Slide grooves 5 are made on the opposite surfaces of the upper beam 4 and lower beam 3 between the left and right columns 1. Sliding blocks are installed at the upper and lower ends of the baffle 6. The installation and movement of the baffle 6 are realized through the sliding cooperation between the sliding blocks and the slide grooves 5. The position of the baffle 6 can be flexibly adjusted along the direction of the beam to meet the protection requirements of composite panels of different sizes. On the one hand, the baffle 6 can block the lateral sliding of the composite panels and prevent the panels from falling due to external force collision or unstable stacking, thus improving the stacking safety. On the other hand, the adjustable position of the baffle 6 can adapt to the stacking of composite panels of various specifications, enhance the versatility of the frame, and reduce the cost caused by replacing different protective structures. The limiting holes 8 and the limiting posts 7 work together to lock the baffle 6 in the designated position to prevent it from sliding and shifting during use. The precise limiting design ensures the stability of the baffle 6 and avoids the protective effect being affected by the loosening of the baffle 6. The four equidistant limiting holes 8 close to the columns 1 can flexibly select the fixed points according to the actual stacking situation of the composite panels, adapt to the stacking requirements of composite panels of different widths, and improve the practicality of the frame.

[0031] Connecting blocks 10 are connected at the angles between the front and rear columns 1 and the upper and lower crossbeams 4 and 3 they are connected to. The connecting blocks 10 are triangular, and support beams 11 are connected between the connecting blocks 10 at opposite corners. The two support beams 11 are intersecting.

[0032] Triangular connecting blocks 10 are connected at the angles between the front and rear uprights 1 and the upper and lower crossbeams 4 and 3. Triangles provide stability, and connecting blocks 10 enhance the rigidity of the connection between the uprights 1 and the crossbeams, disperse the stress in this area, effectively improve the structural strength of key nodes of the frame, reduce the risk of component damage due to stress concentration, enhance the overall deformation resistance of the frame, extend the service life of the device, and ensure the stability of the composite slabs during stacking. The triangular connecting blocks 10 at the corners are connected by cross-shaped support beams 11, forming an "X" shape. The cross support beams 11 can distribute and transfer the load in the diagonal direction of the frame, enhance the frame's resistance to torsion and lateral displacement in the plane, significantly improve the spatial stability of the frame, and effectively suppress the torsion and tilting of the frame when the composite slabs are stacked and eccentric loads are generated or when they encounter lateral forces such as external wind, further reducing the risk of collapse and ensuring the safety of the construction site.

[0033] The upper beam 4 connecting the front and rear columns 1 is connected to a fixing plate 9 on its side wall. The other end of the fixing plate 9 is connected to a threaded rod 12, which passes through the upper beam 4 and is threadedly connected to it.

[0034] By rotating the lead screw 12, the extension length of the lead screw 12 can be adjusted, thereby applying a certain pressure to the top of the composite plate, which plays a role in limiting and fixing. It can flexibly adjust the constraint force on the plate according to the stacking height of the composite plate and actual needs, preventing vertical displacement of the composite plate during stacking. The adjustment structure of the lead screw 12 is easy to operate, making it convenient for construction personnel to make quick adjustments, improving on-site work efficiency, and enhancing the fixing effect of the frame on the composite plate.

[0035] Working principle:

[0036] The uprights 1, made of rectangular steel pipes, bear the vertical load of the composite slab. The bottom base 2 is anchored to the ground with anchor bolts to form a rigid support. The uprights 1, distributed longitudinally and laterally, are welded to the upper and lower beams 3 to form a "well" shaped frame. The deformation of the uprights 1 is limited by the force distribution and transmission, so as to achieve overall stable load bearing. The beams between the left and right uprights 1 are equipped with sliding grooves 5. The baffles 6 are adjusted by sliding the slider to fit the sides of the composite slabs of different sizes. They are then locked by the limiting holes 8 and limiting posts 7 of the lower beams 3 to form an adjustable lateral protection structure. The baffles 6 slide. The triangular connecting blocks 10 at the angle between the uprights 1 and the beams enhance the rigidity of the nodes by utilizing geometric stability. The diagonally cross support beams 11 form a spatial truss. When encountering eccentric loads or lateral forces, the loads are mutually transmitted and offset to suppress the torsional tilt of the frame. The threaded rods 12 on the side wall of the upper beams 4 pass through the beams through the threaded engagement. The extension length can be adjusted by rotating the threaded rods 12 to apply pressure to the top of the composite slabs. The constraint force can be flexibly controlled according to the stacking height to prevent vertical displacement of the slabs.
