Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary structures for steel structure construction, in particular to a walkway structure used for the upper construction of a roof grid steel structure. Background Art

[0002] Most stadium roof trusses use steel structures such as tube trusses, trusses, and bolt ball grids. After the roof trusses are completed, it is often necessary to manually install the decorative panels on the upper part. In this process, providing construction workers with a safe path to facilitate the implementation of the next step has become a technical difficulty. The commonly used method is to use a crane to lay steel plates on the upper part of the installed steel structure, and then spot weld the steel plates to the steel structure, and workers step on the steel plates to lay the decorative panels; or directly lay scaffolding boards on the roof steel structure and use wire binding to securely use as a path, and then workers lay the decorative panels on it.

[0003] The above two methods of building temporary roads have limitations: (1) Spot welding of steel plates will damage the roof structure, and some designs do not allow temporary welding on the structure; (2) Fixing of steel plates increases welding labor and materials, which increases construction costs; (3) The use of binding wire to tie the scaffolding boards has a poor fixing effect; (4) Installation and disassembly are inconvenient, the construction speed is slow, and the efficiency is low. The above temporary roads cannot be moved after being fixed, and their application is inflexible and inconvenient. Utility Model Content

[0004] The utility model provides a walkway structure for the upper construction of a roof grid steel structure, aiming to solve the technical problems of inconvenient installation and removal, immovability, large material input, high construction cost and poor application effect in the construction of an artificial walkway on the upper part of a steel structure roof truss.

[0005] To achieve this technical purpose, the utility model adopts the following scheme: a walkway structure used for the upper construction of a roof grid steel structure, comprising a hook, a connecting chain and a detachable pedal; hooks are hinged on the upper, lower and middle parts of the connecting chain respectively, the hooks are hooked on the rod body of the roof grid steel structure, the connecting chains are used in pairs, segmented pedals are installed in the middle of the two connecting chains, and plate hooks are hinged on both sides of the upper and lower ends of each pedal, and the plate hooks are hooked on the connecting chain buckles to form a walkway structure.

[0006] Compared with the prior art, the beneficial effects of the utility model are: the structure adopts a flexible hook installation form, which is convenient for loading and unloading and can be moved to other construction positions at will; the pedal is detachable, and the length of the overall walkway can be adjusted at will according to actual needs, and the pedal is a segmented structure, which better fits the curvature of the roof and is safer.

[0007] Preferably, a gap is left between the pedals to provide a movable space when the pedal is bent, so that the pedal fits more closely to the steel structure of the roof, thereby improving safety.

[0008] Preferably, an annular groove is opened on the pedal, a binding wire is wound in the groove, and a hanging plate hook is passed through the binding wire. Compared with punching holes on the pedal to install the plate hook, this form causes less damage to the structural strength of the pedal.

[0009] Preferably, the hook is a semi-enclosed hook, and the steel structure rod body is sleeved in the hook to avoid the risk of unhooking. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0014] like Figure 1 and Figure 2 As shown, the utility model provides a walkway structure for the upper construction of a roof grid steel structure, including a connecting chain 1, a hook and a detachable pedal 5. The connecting chain 1 is a buckle connection form, such as an iron chain. A hook is hinged at the upper and lower ends of the connecting chain 1, namely an upper hook 2 and a lower hook 3. A plurality of middle hooks 4 are arranged at intervals in the middle of the connecting chain 1. At least two connecting chains 1 are used together, and three or four or more can be used at the same time. The positions of the middle hooks 4 on the connecting chain 1 are generally arranged symmetrically. Preferably, the hook adopts a semi-enclosed hook or a mountaineering hook to avoid unhooking and eliminate safety hazards; and the bending diameter of the hook head is directly matched with the steel structure rod body 8.

[0015] A detachable pedal 5 is installed in the middle of every two connecting chains 1. The pedal 5 is a multi-section combination. A gap is left at the upper and lower ends of two adjacent pedals 5 as a movable space when the whole pedal is bent, so that the pedal 5 is more closely fitted to the roof steel structure, and no overly protruding bulges will appear during walking, thereby improving safety.

[0016] The upper and lower parts of each pedal 5 are respectively provided with circumferential grooves with a small groove depth. The grooves are wound with binding wires 7, and the binding wires 7 are used to hang the board hooks 6 on the pedals 5. At this time, the board hooks 6 can be rotated to adjust the angle, but will not move longitudinally along the side wall of the pedals 5. The board hooks 6 are hooked on the ring buckle of the connecting chain 1, so that the pedals 5 are connected to the connecting chain 1 to form a walkway structure. Preferably, the board hooks 6 are semi-enclosed hooks or mountaineering hooks to avoid unhooking.

[0017] Installation method: First, install the steel structure of the roof truss. After the installation is completed, lay the connecting chain 1 with hooks on the roof truss net structure, wherein the upper hook 2 hooks the horizontal connecting rod at the top of the roof truss, the lower hook 3 hooks the horizontal connecting rod at the bottom of the roof truss, and the middle hook 4 hooks the horizontal connecting rod and connecting rod adjacent to the roof truss, so that it is fixed and firmly laid on the upper part of the steel structure of the roof truss. Then, place the pedal 5 between the two connecting chains 1 and lay it on the upper part of the roof truss net structure, and the hook head of the plate hook 6 hooks in the adjacent connecting chain 1 ring buckle, so that the pedal 5 and the connecting chain 1 form a whole, and the production and installation of the walkway structure are completed. During the construction process, the walkway structure is used as a fulcrum, and the workers can walk on the walkway structure. The walkway structure can be flexibly moved during construction. By unhooking the upper hook 2, the lower hook 3, and the middle hook 4, the end or bottom of the connecting chain 1 can be dragged to move horizontally or vertically, and then the upper hook 2, the lower hook 3, and the middle hook 4 hook heads can be hooked to continue construction. The pedal 5 does not need to be disassembled during the overall movement, and the pedal 5 is only disassembled when adjusting the length of the walkway. The device is easy to use, flexible, safe and easy to dismantle.

[0018] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
