Description

Technical Field

[0001] This invention relates to the technical field of construction platforms, and in particular to a construction platform walkway slab and its laying process. Background Technology

[0002] Existing construction platforms mostly use wooden walkways. Since the cooling tower has a ring-shaped shell structure and the template is assembled in a ring, the walkways are arranged in a ring. Each template has 2-4 wooden walkways. Adjacent templates are connected by a socket structure. Each walkway consists of a wooden board about 30mm thick and two 50*100mm timbers. The wooden board is sequentially fixed to the two timbers and assembled. The timbers are used as the main load-bearing beams and are set up in a V-shape, overlapping the angle steel tripods that are set at equal intervals around the cooling tower. The V-shape structure facilitates the socket setting of the timbers at the adjacent ends.

[0003] The existing walkways for cooling tower construction are all made of wood, which has a short service life, low strength, and requires regular maintenance and replacement, resulting in high construction costs and low safety. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide a construction platform walkway slab and its laying process to solve the problems existing in the prior art, making the walkway slab sturdy, durable and with a high safety factor.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figures 1 to 3 As shown: This embodiment provides a construction platform walkway, including a metal walkway 1 and a limiting groove. The projected surface of the metal walkway 1 is trapezoidal. The long bottom end of the metal walkway 1 is provided with a limiting groove, which is used to be inserted into the crossbar of the tripod 6. The waist length of the metal walkway 1 is greater than the spacing between the crossbars of the adjacent tripod 6. The long bottom end and the short bottom end of the metal walkway 1 are respectively connected to the crossbars of the adjacent tripod 6, and the long bottom end is connected above the short bottom end of the adjacent metal walkway 1.

[0033] As an optional solution, in this embodiment, the upper surface of the metal walkway 1 is provided with at least one movable handle 2. The movable handle 2 is located at one end of the metal walkway 1, and the upper part of the movable handle 2 can fit against the upper surface of the metal walkway 1. The pull-out structure is convenient for storage and does not affect normal walking on the walkway.

[0034] As an optional solution, in this embodiment, the movable handle 2 is an inverted U-shaped metal rod with limiting flanges at both ends. The metal walkway plate 1 is provided with at least one pair of insertion holes. The two ends of the movable handle 2 are respectively movably inserted into one insertion hole. The diameter of the limiting flange is larger than the diameter of the insertion hole, so that the handle is limited in the insertion hole and cannot come out. In this embodiment, the movable handle 2 is preferably a round steel with a diameter of about 12mm, and one is provided at each of the two bottom ends. When the movable handle 2 is not in use, it can be allowed to fall back and adhere to the upper surface of the metal walkway plate 1 by gravity, so as to avoid affecting normal walking.

[0035] As an optional solution, the upper surface of the metal walkway 1 in this embodiment is provided with anti-slip texture, which has good anti-slip properties and can ensure the strength and safety of construction workers.

[0036] As an optional solution, in this embodiment, the metal walkway 1 is evenly distributed with several through holes 3, the diameter of which is 20mm-25mm. In this embodiment, the through holes 3 are impact holes, which can release water accumulated on the metal walkway 1, increase the friction of the panel, and reduce weight, thus ensuring the strength and safety of construction workers.

[0037] As an optional solution, in this embodiment, side reinforcing ribs 7 are provided on both sides of the metal walkway 1. The side reinforcing ribs 7 are arranged parallel to the two waist edges of the metal walkway 1 and have the same length, which can enhance the support strength of the metal walkway 1. At least two transverse reinforcing ribs 4 are provided between the two side reinforcing ribs 7. The transverse reinforcing ribs 4 are arranged parallel to the long bottom edge or short bottom edge of the metal walkway 1, which can prevent the side reinforcing ribs 7 on both sides from deforming or cracking.

[0038] As an optional solution, the material of the metal walkway 1 in this embodiment includes metal and metal alloy, such as aluminum alloy, carbon steel, or stainless steel. In this embodiment, the walkway 1 is made of 3mm thick steel plate, with a total thickness of 50mm. Furthermore, to prevent rust, the walkway 1 is hot-dip galvanized. The metal walkway 1 is an isosceles trapezoid with a difference of 3cm-5cm between its two bases, facilitating angular misalignment when overlapping curved or circular walkways.

[0039] As an optional solution, in this embodiment, the length of the metal walkway 1 is 100cm-130cm, preferably 120cm. The height of the side reinforcing ribs 7 and the transverse reinforcing ribs 4 is 4cm-6cm. Three transverse reinforcing ribs 4 are provided between the two side reinforcing ribs 7, and the three transverse reinforcing ribs 4 are located at distances of 2-3cm, 60cm, and 90cm from the short bottom edge of the metal walkway 1, respectively. The long bottom end of the metal walkway 1 does not have transverse reinforcing ribs 4, and can be easily overlapped (fastened) directly onto the short bottom end without obstruction.

[0040] As an optional solution, in this embodiment, the limiting groove includes two metal cylinders 5 welded to the bottom surface of the metal walkway plate 1. The metal cylinders 5 are located on one side of the long bottom end of the metal walkway plate 1, and the distance between the two metal cylinders 5 is 0.5cm-2cm greater than the width of the crossbar of the tripod 6. The height of the metal cylinders 5 is 8cm-10cm, which is about 3cm higher than the transverse reinforcing rib plate, so as to facilitate insertion into the crossbar of the tripod 6 and reserve a certain amount of movement space in the width direction of the crossbar, so as to facilitate angular misalignment when overlapping arc-shaped or circular walkways.

[0041] As an optional solution, in this embodiment, the long bottom end of the metal walkway 1 overlaps the short bottom end of the adjacent metal walkway 1, and the short bottom end of the metal walkway 1 directly overlaps the crossbar of the tripod 6. The metal cylinder 5 is located outside the short bottom end of the adjacent metal walkway 1. In this embodiment, the metal walkway 1 is overlapped using a tile-like method, which ensures a secure overlap.

[0042] Example 2

[0043] like Figure 3 As shown: This embodiment relates to a construction platform walkway slab laying process, based on the aforementioned construction platform walkway slab, specifically including the following steps:

[0044] S1. Prefabricate the metal walkway 1 according to the spacing of the crossbars of the tripod 6 on the construction platform, so that the spacing between the two bottom edges of the metal walkway 1 is 15cm-30cm greater than the spacing of the crossbars of the tripod 6. In this embodiment, 15cm is preferred. Then transport the metal walkway 1 to the tripod 6.

[0045] S2, first hold one movable handle 2 and place the metal walkway 1 on the crossbars of the two adjacent tripods 6, so that the bottom limiting groove is inserted into both sides of the crossbar of one tripod 6. Then hold the other movable handle 2 and place the short bottom end of the metal walkway 1 on the corresponding crossbar of the tripod 6. Finally, adjust the overlapping direction of the metal walkway 1 according to the direction of the construction platform.

[0046] S3, repeat S2, so that the long bottom end of the next metal walkway slab 1 overlaps the short bottom end of the previous metal walkway slab 1, and the limiting groove of the metal walkway slab 1 is inserted into the crossbar of the tripod 6 where the short bottom end of the previous metal walkway slab 1 is located. Adjust the direction of the metal walkway slab, and repeat the above operation until a walkway or two parallel walkways are erected on the construction platform. The walkways include curved, circular or straight types.

[0047] In this embodiment, the metal walkway panel 1 is a trapezoidal panel designed with a structure that is wider at one end and narrower at the other. The wider end can cover the narrower end. Combined with the annular structure of the cooling tower, the walkway panels can be arranged in a ring, ensuring an arc-shaped transition between adjacent panels. To prevent the walkway panels from slipping to either end, a welded limiting groove is provided at the wider end, securing it to the crossbar of the template tripod 6. Simultaneously, to facilitate installation or relocation, two movable handles are provided on the walkway panels. Furthermore, corresponding impact holes are provided on the walkway panel surface to prevent water accumulation and increase panel friction, ensuring the safety of workers. The metal walkway panels of this embodiment can be reused for a long time, saving wood and reducing costs. They are structurally reliable and stable in use, requiring virtually no maintenance. Assembly and use are convenient, operation is simple, and no installation skills are required.

[0048] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
