Description

Technical Field

[0001] This utility model belongs to the field of building construction technology and relates to a walkway slab, specifically an adjustable inter-floor expansion joint walkway slab. Background Technology

[0002] With rapid societal development and the emergence of large-scale buildings, to prevent uneven settlement due to excessive structural size and length, expansion joints are typically installed within 40 meters of the building during structural design, dividing the excessively long structure into two or more sections. A certain width of expansion joint is left between two construction sections. This expansion joint is maintained for an extended period before the completion of the finishing phase, serving as a necessary passage for material transport, using temporary walkways to move materials from one side to the other. However, the expansion joint location also presents certain safety hazards. If the walkway slab is not strong enough, it cannot be used as a passageway, and there is a risk of falling objects penetrating it. Given the current construction conditions, an adjustable inter-floor expansion joint walkway slab is designed to serve both as a temporary passageway and improve safety. Utility Model Content

[0033] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0034] See Figures 1 to 9This embodiment proposes an adjustable inter-floor expansion joint walkway, including a base 1 and two walkway unit 2. The base 1 includes two main ribs 11 and multiple diagonal braces 12. Multiple connecting grooves 13 are evenly distributed along the axial direction on the inner side of the main ribs 11, and a rotating shaft 14 is provided inside the connecting grooves 13. The two ends of the multiple diagonal braces 12 are rotatably connected to the rotating shafts 14 in the connecting grooves 13 corresponding to the two main ribs 11. The base 1 of this device uses the principle of a laptop stand. The main ribs 11 serve as the main frame on both sides of the base 1, and a row of diagonal braces 12 serves as the connecting member in the middle. The main ribs 11 and the diagonal braces 12 form a parallelogram structure. By twisting the diagonal braces 12, the distance between the two main ribs 11 can be adjusted, thereby adjusting the width of the base 1.

[0035] The main rib 11 is equipped with a snap-fit ​​structure 15; the floor slabs 3 on both sides of the expansion joint are provided with corresponding slots, and the base 1 is engaged with the slots of the floor slabs 3 through the snap-fit ​​structure 15 on both sides; in this embodiment, the snap-fit ​​structure 15 is an L-shaped structure, which is axially arranged at the bottom of the outer side of the main rib 11, and the slot is an L-shaped slot that engages with the L-shaped structure. This snap-fit ​​structure allows the base 1 to be engaged with the concrete floor slab during placement, preventing displacement during use.

[0036] The walkway slab unit 2 includes a sloping panel 21, a fixed plate 22, and a telescopic plate 23. The high-slope side of the sloping panel 21 is welded to one side of the fixed plate 22. A groove is provided on the other side of the fixed plate 22, and the telescopic plate 23 is slidably connected to the fixed plate 22 through the groove. Three telescopic buckle holes 24 are provided at both ends of the fixed plate 22, and three telescopic buckles 25 are correspondingly provided at both ends of the telescopic plate 23. The telescopic buckles 25 and the telescopic buckle holes 24 are connected in a cooperative manner. The telescopic plates 23 of two walkway slab units 2 are welded to adjacent sides. The main rib 11 of the base 1 is fixedly connected to the bottom of the connection between the sloping panel 21 and the fixed plate 22. This allows for adaptation to floor expansion joints of different widths.

[0037] Specifically, in this embodiment, the inner wall of the chute is provided with a slide rail, and the two ends of the telescopic plate 23 are slidably connected in the slide rail.

[0038] The telescopic buckle 25 includes a buckle body, and three circular grooves are evenly distributed at both ends of the telescopic plate 23. Each circular groove is connected to the buckle body through a connecting spring.

[0039] Both the base 1 and the walkway panel 2 are made of aluminum alloy; they are lightweight, high-strength, corrosion-resistant, easy to process, have good surface flatness, are not easily damaged or deformed during use, have a low damage rate over long-term use, can be reused, and have a high utilization rate.

[0040] This embodiment describes a method for using an adjustable inter-floor expansion joint walkway slab:

[0041] After the main structure on both sides of the expansion joint is completed, this device is adjusted in advance according to the width of the expansion joint and placed at the expansion joint. It is placed stably by matching the buckle structure 15 at the bottom of the base 1 with the groove of the floor slab 3. It serves as a floor passage plate on both sides of the expansion joint and can also serve as horizontal protection at the expansion joint location.

It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
