Description

Technical Field

[0001] The utility model belongs to the technical field of floor fixing devices, and more specifically, relates to a wooden formwork fixing device and a formwork fixing system. Background Art

[0002] During the construction of floor and beam formwork, the wooden formwork often warps with a large arc at the four sides due to high temperature or other factors, resulting in affecting the binding of beam and slab steel bars, failing to meet the designed camber requirements, and affecting the concrete forming quality. Currently, the common construction methods are to sprinkle water for curing the formwork or use wooden squares for fixing, but there are several drawbacks. Firstly, sprinkling water for curing makes the formwork surface very slippery, greatly reducing the construction safety. Secondly, the timeliness of dealing with the warped edges of the formwork by sprinkling water for curing is very low, and it is difficult to meet the construction requirements under large area and high temperature conditions. Finally, the method of fixing with wooden squares requires higher transportation costs and the sizes are not uniform, and it is impossible to accurately clamp in the middle of the formwork support.

[0041] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] Embodiment 1:

[0043] As Figures 1 - 6 shown, the present utility model provides a wood formwork fixing device, and the wood formwork fixing device includes:

[0044] A plate-like component 1, a mounting hole 2 and a rod-shaped connecting piece 5. The plate-like component 1 includes a first structural surface 101 and a second structural surface 102. The first structural surface 101 and the second structural surface form a pair of opposite surfaces of the plate-like component 1;

[0045] The mounting hole 2 is provided on the plate-like component 1 and penetrates from the first structural surface 101 to the second structural surface 102. The number of the mounting holes 2 is multiple and symmetrically distributed along the tangent of the plate-like component 1;

[0046] The size and number of the rod-shaped connecting pieces 5 are adapted to the size and number of the mounting holes 2, and are used to detachably connect a pair of the wood formworks by passing the rod-shaped connecting pieces 5 into the symmetrically distributed mounting holes 2.

[0047] Specifically, an innovative wooden formwork fixing device in Embodiment 1 aims to solve the problems of low formwork fixing efficiency, preventing the curling of wooden formwork, and unstable connection in the prior art. This wooden formwork fixing device mainly consists of three key parts: a plate-shaped component 1, mounting holes 2, and rod-shaped connectors 5. These components work together to achieve the rapid and stable connection of wooden formwork.

[0048] The plate-shaped component 1 is the core part of this device. It has two opposite structural surfaces, namely the first structural surface 101 and the second structural surface 102. These two structural surfaces are opposite to each other and constitute the main body of the plate-shaped component 1. To achieve the fixing of the formwork, multiple mounting holes 2 are designed on the plate-shaped component 1. These mounting holes 2 penetrate from the first structural surface 101 to the second structural surface 102 and are distributed in a tangentially symmetric manner, ensuring uniform force and structural stability during formwork fixing.

[0049] The rod-shaped connector 5 is the key component for realizing the connection of the formwork. Its size and quantity match those of the mounting holes 2 to ensure the tightness and reliability of the connection. The rod-shaped connector 5 is inserted into the mounting hole 2 to detachably connect a pair of wooden formworks. This design not only facilitates the installation and disassembly of the formwork but also improves the construction efficiency and the reuse rate of the formwork.

[0050] In the specific implementation process, first, it is necessary to determine the specifications of the plate-shaped component 1 according to the size and shape of the wooden formwork, and then accurately machine the required mounting holes 2. Subsequently, according to the distribution of the mounting holes 2, select appropriate rod-shaped connectors 5 for insertion. When connecting the wooden formwork, it should be ensured that the rod-shaped connector 5 correctly passes through the corresponding mounting hole 2 and, if necessary, use fasteners for fixation to enhance the stability of the connection.

[0051] In addition, to adapt to different construction environments and requirements, both the plate-shaped component 1 and the rod-shaped connector 5 of this device can be adjusted and optimized accordingly. For example, the size of the mounting hole 2 can be adjusted according to the material and thickness of the wooden formwork, or the material of the appropriate rod-shaped connector 5 can be selected according to the specific requirements of the construction to meet the needs of different strengths and durabilities.

[0052] In summary, the wooden formwork fixing device provided by the present utility model, with its unique design and structure, effectively solves the problems existing in the traditional formwork fixing method. It has the advantages of simple operation, firm connection, easy disassembly, etc., is applicable to various building construction scenarios, and has good market application prospects and practical value.

On these two structural plates, a plurality of mounting holes 2 are designed, and these mounting holes 2 are correspondingly distributed to ensure uniform force and structural balance when the formwork fixing device is connected to the formwork.

[0055] To further improve the stability of the formwork fixing device and facilitate adjustment, the device further includes a first stainless steel support rod 301 and a second stainless steel support rod 302. One end of the first stainless steel support rod 301 is fixedly connected to the first structural plate, while the other end of the second stainless steel support rod 302 is fixedly connected to the second structural plate.
