Description

Technical Field

[0001] This utility model relates to the field of overlapping plate splicing technology, specifically to an overlapping plate for pedestrian walkways in building construction. Background Technology

[0002] Overlap boards are a type of construction tool used in the construction industry. They are generally referred to as steel scaffolding boards, construction steel planks, steel treads, galvanized steel planks, and hot-dip galvanized steel treads. They are widely used in oil platforms, power plants, and the construction industry.

[0003] In existing technologies, the joints of metal lap plates are prone to water and dust accumulation. When exposed to humid and dusty environments for a long time, they are prone to corrosion, which can cause the joints to jam. In addition, some lap plates rely on fasteners such as bolts and nuts for splicing, and each plate needs to be tightened with tools multiple times to fix it. The splicing operation of lap plates is difficult and time-consuming. Utility Model Content

A support plate for splicing is provided in the fixing groove.

[0009] Both sides of the support plate are provided with L-shaped side plates. The support plate between the side plates is provided with cylindrical sliding grooves, and multiple sliding balls are provided in the sliding grooves. The side of the substrate away from the fixed plate is provided with a limiting groove for sliding on the support plate. The limiting groove is provided at both ends of the substrate. Both sides of the substrate are provided with two fixing strips, and the two fixing strips are slidably connected to the L-shaped side plates on both sides of the fixed plate.

[0010] Furthermore, each of the limiting grooves of the substrate is provided with an arc-shaped groove, which is located in the middle of the limiting groove. The arc-shaped groove is used to support the sliding of the ball bearings on the plate.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: A pedestrian lap slab for building construction, such as Figure 1-4 As shown, it includes a base plate 1 and a fixing plate 2. The fixing plate 2 is provided with a plurality of rectangular grooves 202 divided by partitions. A long strip-shaped fixing groove 201 is provided in the middle of the plurality of grooves 202. A splicing support plate 3 is provided in the fixing groove 201.

[0028] L-shaped side plates 21 are provided on both sides of the support plate 3 and the fixed plate 2. A cylindrical sliding groove 301 is provided on the support plate 3 between the side plates 21. Multiple sliding balls 31 are provided in the sliding groove 301. A limiting groove 101 for sliding on the support plate 3 is provided on the side of the base plate 1 away from the fixed plate 2. The limiting groove 101 is provided at both ends of the base plate 1. Two fixing strips 12 are provided on both sides of the base plate 1. The two fixing strips 12 are slidably connected to the L-shaped side plates 21 on both sides of the fixed plate 2.

[0029] With the setting of the fixing plate 2, the multiple sets of rectangular grooves 202 on the fixing plate 2 cooperate with the support plate 3 in the central fixing groove 201, which facilitates the rapid splicing of multiple overlapping plates. The overall length or width can be flexibly adjusted according to the width of the construction site to adapt to the needs of passages with different spans. Moreover, the partitions around the multiple sets of rectangular grooves 202 on the fixing plate 2 greatly improve the rigidity and bending strength of the plate, so that the overlapping plate can withstand heavier loads without bending deformation. The base plate 1 cooperates with the ball bearings 31 of the support plate 3 through the limiting groove 101, and cooperates with the sliding connection between the fixing strip 12 and the L-shaped side plate 21, so that the base plate 1 and the fixing plate 2 can be relatively stretched or finely adjusted in position, which can easily cope with complex working conditions such as uneven ground and slope changes, and improve the installation adaptability.

[0030] Furthermore, each of the limiting grooves 101 of the substrate 1 is provided with an arc-shaped groove 102, which is located in the middle of the limiting groove 101. The arc-shaped groove 102 is used to support the sliding of the ball bearings 31 on the support plate 3.

[0031] By setting the arc groove 102, when the substrate 1 and the support plate 3 are spliced, the limiting groove 101 and the ball 31 cooperate to ensure that the limiting groove 101 at the bottom of the multiple overlapping plates and the support plate 3 can slide smoothly when spliced, and limit the sliding trajectory of the overlapping plates, preventing the multiple overlapping plates from being misaligned or twisted during splicing, which greatly enhances the overall stability.

[0032] Furthermore, the side of the support plate 3 away from the fixed plate 2 is provided with two sets of straight inclined grooves 302, which are located on both sides of the slide groove 301. The support plate 3 is provided with locking plates 32 that restrict the ball bearings 31 from sliding out. The locking plates 32 are located at both ends of the cylindrical slide groove 301. The side of the support plate 3 near the fixed plate 2 is provided with a drainage groove 303 for drying the ball bearings 31. The drainage groove 303 is located directly below the slide groove 301.

[0033] With the addition of the inclined groove 302 and drainage groove 303 on the support plate 3, the inclined groove 302, drainage groove 303 and ventilation groove 203 together form an active drainage system. Rainwater will flow away along the inclined groove 302 and be discharged outside the overlapping plate through the drainage groove 303, without accumulating. In addition, the inclined groove 302 on both sides of the support plate 3 allows the overlapping plate to be used independently and enhances the grip between the foot and the support plate 3 on the overlapping plate, especially improving safety in wet environments.

[0034] Furthermore, the fixing plate 2 is provided with a ventilation groove 203 on the side close to the substrate 1. The ventilation groove 203 is used to connect multiple sets of rectangular grooves 202 on the substrate 1.

[0035] By setting the ventilation groove 203, air can circulate in the internal groove 202, quickly evaporate moisture, keep the surface of the substrate 1 and the fixing plate 2 dry, and keep the area where the slide 301 and the ball 31 are located dry. This effectively prevents the ball 31 and the slide from rusting, corroding, or getting stuck due to water accumulation, and extends the service life of the product.

[0036] Furthermore, an anti-slip pad 11 is provided on the side of the substrate 1 away from the fixing plate 2, and the outline of the pad 11 is H-shaped.

[0037] By setting the pad 11, the anti-slip pad 11 set on the side of the substrate 1 away from the fixing plate 2 can increase the friction of the H-shaped anti-slip pad 11 on the surface of the substrate 1, and prevent construction workers from slipping when walking on the overlapping plate.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
