Technical Field
[0001] The utility model relates to the technical field of building installation tools, in particular to an aluminum-wood template joint connection and positioning device. Background Art
[0002] The combined aluminum and wood formwork construction process demonstrates its unique advantages at the intersection of non-standard and standard floors. By combining aluminum alloy formwork with wood formwork, the process not only ensures that the majority of the structure achieves the high precision and quality expected of aluminum formwork, but also ensures that construction nodes are completed in one go, eliminating the need for secondary construction, saving costs, and ensuring improved construction quality.
[0003] However, in the existing aluminum-wood combined construction technology, the quality of the forming at the joint between the aluminum mold and the wooden mold is poor, and quality defects such as "misalignment, mold explosion, slurry leakage, and honeycomb surface" often occur. The main reason for such problems is that the thickness, material, strength, stiffness and other performance indicators of the aluminum mold and the wooden mold are completely inconsistent, resulting in an inability to connect and fix, which brings great inconvenience to the construction, causes secondary rework and repair, and increases construction costs.

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.
[0020] See Figures 1-4 , the utility model provides a technical solution:
[0021] like Figures 1-4As shown, an aluminum-wood formwork joint connection and positioning device is located on one side of a vertical structure 1 and is used to connect the aluminum formwork 2 and the wood formwork 3, including a pull tab 4, a base plate 5 and a positioning plate 6, the base plate 5 is fixed on one side of the pull tab 4 and forms a T-shaped structure with the pull tab 4, the positioning plate 6 is fixed on the pull tab 4 and close to the base plate 5, the pull tab 4 is provided with a pin hole 7 on the side away from the positioning plate 6 and the base plate 5, and a pin piece 8 is correspondingly provided in the pin hole 7; the aluminum formwork 2 is located on the side of the pull tab 4 where the positioning plate 6 is not provided, and one side of the base plate 5 is inserted between the vertical structure 1 and the aluminum formwork 2; the wood formwork 3 is located between the base plate 5 and the positioning plate 6, and the positioning plate 6 is provided with a wooden square 9 on the side away from the wooden formwork 3, and the wooden formwork 3 and the aluminum formwork 2 are fixed by the wooden square 9, the pin hole 7 and the pin piece 8.
[0022] Through the above technical solution, the bottom aluminum alloy formwork is first installed on one side of the vertical structure 1, and then one side of the bottom plate 5 is inserted between the aluminum formwork 2 and the vertical structure 1. At this time, the positioning plate 6 is facing upward. Since the distance between the bottom plate 5 and the positioning plate 6 is adapted to the thickness of the wooden formwork 3, the wooden formwork 3 is inserted between the bottom plate 5 and the positioning plate 6. Due to the difference in thickness between the wooden formwork 3 and the aluminum formwork 2, the widths of the wooden formwork 3 and the wooden formwork 9 are adapted to the width of the aluminum formwork 2 by placing wooden squares 9, and then the pins 8 are inserted into the pin holes 7 so that the pins 8 are pressed against the wooden squares 9 and the aluminum formwork 2 to complete the fixation. At the same time, multiple connection and positioning devices are used to improve the connection strength between the aluminum formwork 2 and the wooden formwork 3. The distance between two adjacent connection and positioning devices is 200mm.
[0023] The connection and positioning device effectively solves the problem of different thicknesses of the aluminum formwork 2 and the wooden formwork 3 and large seams at the connection, making the connection firm, easy to install, and improving installation efficiency.
[0024] Furthermore, the widths of the wooden template 3 and the wooden square 9 are adapted to the width of the aluminum template 2 , and the distance between the pin hole 7 and the bottom plate 5 is adapted to the width of the aluminum template 2 .
[0025] Through the above technical solution, a suitable wooden square 9 is selected according to the thickness of the aluminum template 2 and the wooden template 3, so that the wooden square 9 and one side of the aluminum template 2 are horizontal, which is convenient for inserting the pin piece 8 to complete the locking. At the same time, the pin hole 7 is located on one side of the wooden square 9 and the aluminum template 2 to prevent the pin piece 8 from being unable to be inserted.
[0026] Furthermore, the pin hole 7 is a square hole, the pin piece 8 is made of a wedge-shaped steel plate, and the thickness of the pin piece 8 is adapted to the width of the pin hole 7 .
[0027] Through the above technical solution, the wooden formwork 3 and the aluminum formwork 2 can be firmly connected by cooperating with the pin piece 8 and the pin hole 7, thereby avoiding looseness and improving the connection effect.
[0028] Furthermore, the pull tab 4, the bottom plate 5 and the positioning plate 6 are all made of galvanized steel plates with a wall thickness of 2 mm.
[0029] Through the above technical solution, the pull tab 4, the base plate 5 and the positioning plate 6 are made of thinner steel plates, which avoids increasing the thickness and reduces installation errors. At the same time, the thinner base plate 5 can be easily inserted between the vertical structure 1 and the aluminum template 2.
[0030] Furthermore, the bottom plate 5 and the pull tab 4, as well as the positioning plate 6 and the pull tab 4 are fixed by welding.
[0031] Through the above technical solution, welding fixation is adopted to improve the overall strength.
[0032] The above description is merely a preferred embodiment of the present invention.
