Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a fixing device and construction method for a scaffolding board during construction. Background Art

[0002] A scaffolding board, also known as a scaffolding sheet, is laid on a scaffold or working platform, and is a temporary and reusable building material that facilitates workers to walk, transfer materials, and carry out construction operations above it. How to quickly and stably lay the scaffolding board on the scaffold is the key and difficult point of the scaffolding board. The usual method of fixing the scaffolding board is to tie and fix the scaffolding board to the steel pipe of the scaffold with iron wire. After the iron wire is twisted, its structure changes and sometimes it breaks, causing safety accidents. Moreover, due to construction needs, the scaffolding board must be frequently repositioned, and it is rather cumbersome to move when fixed with iron wire. Summary of the Invention

[0003] The technical problem to be solved by the present invention is the problem that the existing scaffolding board is not firmly fixed to the steel pipe of the scaffold and is difficult to disassemble.

[0004] To solve the above problems, the present invention provides a fixing device and construction method for a scaffolding board that can improve the stability of the scaffolding board and can be quickly disassembled and assembled at the same time; The first technical solution of the present invention is: A fixing device for scaffolding board construction is applied to the scaffold at the construction site. At least two groups of fixing devices are provided, and each fixing device is respectively arranged on each horizontal pipe of the scaffold. The fixing device includes a fixing plate and a fixing pipe. The fixing plate is used for lapping on the horizontal pipe of the scaffold. At the front end and the rear end of the bottom of the fixing plate, there are provided clamping components for clamping the horizontal pipe. A plurality of fixing pipes are arranged side by side on the fixing plate. The fixing pipes penetrate through left and right, and the horizontal positions of the fixing pipes of different fixing devices respectively correspond one by one. Each scaffolding board is used for being inserted into each corresponding fixing pipe, and a wedge is connected inside the fixing pipe between the scaffolding board and the fixing pipe.

[0005] As a preference, a further technical solution of the present invention is: The clamping component includes a plurality of U-shaped buckles. On the same straight line at the bottom of the fixing plate, there are provided buckle holes corresponding to the number of U-shaped buckles. The top of each U-shaped buckle is used for passing through the corresponding buckle hole and being threadedly connected with a nut. The horizontal pipe of the scaffold is used for being inserted into each U-shaped buckle at the bottom of the fixing plate.

[0006] The distances between the fixing pipes on the fixing plate are equal, and there are threaded holes opened at the top of the fixing pipes. Screws are threadedly connected in the threaded holes, and the inner ends of the screws are used for tightly abuting against the scaffolding board in the fixing pipe.

[0007] The first technical solution of the present invention is: A construction method for a scaffolding board is applied to the above fixing device and includes the following steps: Step 1: Predetermine the span of the horizontal pipe where the scaffolding board is to be installed, determine the number of fixing devices according to the number of horizontal pipes to be installed, and prepare a corresponding number of steel plates as fixing plates; Step 2: Select steel pipes with a larger diameter than the scaffolding board as fixed pipes, determine the number of scaffolding boards to be laid, and weld the same number of fixed pipes side by side on each fixed board in advance, so that the axes of the fixed pipes on the same fixed board are parallel; Step 3: overlap each fixing plate to the horizontal tube of the scaffolding board to be installed, match the positions of each fixing tube of each fixing device, and fix the fixing plate and the horizontal tube by a clamping assembly; Step 4: Insert the scaffolding boards into the corresponding fixing tubes at each position, and drive wooden wedges into the gaps between the fixing tubes and the scaffolding boards to fix the positions of the scaffolding boards.

[0008] Preferably, a further technical solution of the present invention is: The clamping assembly adopts a U-shaped clamp, and clamp holes are opened at the front and rear ends of the bottom of the fixing plate. The U-shaped clamp clamps the cross tube from below the cross tube, and the top of the U-shaped clamp is used to pass through the corresponding clamp hole and threadedly connect the nut above the fixing plate.

[0009] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: By means of the fixing device of the present invention, the fixing plate is detachably mounted on the horizontal tube through a clamping assembly, and the fixing tube is fixed on the fixing plate. The scaffolding board is inserted into the fixing tubes at both ends to define the position of the scaffolding board, and is fixed between the scaffolding board and the fixing tube by means of wooden wedges, so that the position of the scaffolding board is fixed, thereby saving the time for installing and fixing the scaffolding board, improving the stability of the scaffolding board, thereby avoiding the risk of construction workers falling and the risk of materials dropping, reducing the occurrence of safety accidents, avoiding the situation of rework caused by unqualified acceptance, and saving labor costs and time costs of rework.

[0012] See attached Figures 1-4 , Embodiment 1 of the present invention discloses a construction fixing device for a scaffolding board 2, which is applied to a scaffolding at a construction site. At least two groups of fixing devices are provided, and each fixing device is respectively provided on each horizontal tube 3 of the scaffolding. The fixing device comprises a fixing plate 1 and a fixing tube 11. The fixing plate 1 is used to overlap the horizontal tube 3 of the scaffolding. The front end and the rear end of the bottom of the fixing plate 1 are provided with a clamping assembly for clamping the horizontal tube 3. A plurality of fixing tubes 11 are arranged side by side on the fixing plate 1. The fixing tubes 11 are passed through from side to side, and the lateral positions of the fixing tubes 11 of different fixing devices correspond to each other one by one.
