Description

Technical Field

[0001] The utility model relates to the technical field of template connection structures, in particular to a building template connection structure. Background Art

[0002] Building formwork is a temporary support structure commonly used in construction. It is used to support the formwork and formwork support system during concrete pouring. It plays the role of carrying concrete and construction personnel and equipment in construction, ensuring that the required structural shape and size are formed after concrete pouring.

[0003] At present, when two templates are connected, the more common connection method is to connect them through pins. The method of use is generally to insert one end of the pin into the reserved holes on the surfaces of the two templates in turn, and then insert a T-shaped steel plate into the inner wall of the slot opened on the surface of the pin and knock the T-shaped steel plate to make the surface of the steel plate contact the surface of the template, thereby realizing the connection of the two templates. After this pin is used once, the slot on the surface will be deformed after being contacted by the T-shaped steel plate. If it is collected together by illegal merchants and then repackaged and sold, it will affect the subsequent construction safety. It is difficult to see whether the inner wall of the slot is damaged by visual inspection alone. Therefore, a new type of building template connection structure is needed to solve the above problems.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides a building template connection structure, which is mainly used to solve the problem that the more common connection method for connecting two templates is to connect them through pins. The method of use is generally to insert one end of the pin into the reserved holes on the surfaces of the two templates in turn, and then insert a T-shaped steel plate into the inner wall of the slot opened on the surface of the pin and then knock the T-shaped steel plate so that the surface of the steel plate is in contact with the surface of the template, thereby realizing the connection of the two templates. After the pin is used once, the slot on the surface will be deformed after being in contact with the T-shaped steel plate. If it is collected together by illegal merchants and then repackaged and sold, it will affect the subsequent construction safety. The problem that it is difficult to see whether the inner wall of the slot is damaged by visual inspection alone is also provided. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0019] A building template connection structure comprises: a pin 1 with a trapezoidal groove 2 on the surface. When in use, the user slides and inserts a trapezoidal plate 3 on the inner wall of the trapezoidal groove 2. Under the action of a limiting mechanism 6, a film sheet 5 is provided on the inner wall of a disassembly hole 4 on the surface of the trapezoidal plate 3. When the pin 1 is disassembled, an iron rod can be inserted into the inner wall of the disassembly hole 4 to pierce the film sheet 5, and then the trapezoidal plate 3 is rotated to drive the pin 1 to rotate. Then, the other end of the trapezoidal plate 3 can be knocked out by knocking with a hammer, so as to realize the removal of the pin 1. The main components of the pin 1 are: a connector 101, a connector 10 1 is provided with a contact head 102, and the user can install the contact head 102 on one end of the connector 101 through the connecting mechanism 7 and then insert one end of the connector 101 into the inner walls of the reserved holes on the surfaces of the two templates in sequence, wherein the limiting mechanism 6 is mainly composed of: a limiting ring 602 fixedly sleeved on the surface of the film sheet 5, and two limiting edges 603 are provided on the surface of the limiting ring 602, and two limiting grooves 601 are provided on the inner wall of the disassembly hole 4, and the two limiting edges 603 are respectively slidably inserted into the inner walls of the two limiting grooves 601, thereby realizing the limiting of the film sheet 5 inside the disassembly hole 4.

[0020] When in use, after inserting the pin 1 into the reserved holes on the surfaces of the two templates and inserting the trapezoidal plate 3 into the inner wall of the trapezoidal groove 2, one end of the trapezoidal plate 3 is knocked by a device such as a knocking hammer so that the surface of the trapezoidal plate 3 is in contact with the surface of the template, and the connection between the two templates can be achieved. When the pin 1 is subsequently removed, the iron rod for removal can be inserted into the inner wall of the disassembly hole 4 to pierce the film 5, and the pin 1 is pulled by the trapezoidal plate 3 to turn it, and then the other end of the trapezoidal plate 3 is knocked out by knocking it with a knocking hammer, and then the pin 1 can be removed. In this way, after the pin 1 is used, the film 5 on the inner wall of the disassembly hole 4 on the surface of the trapezoidal plate 3 will be damaged, which can be used for identification to avoid secondary use, thereby fully reflecting the practicality of the device.

[0021] like Figure 1 , Figure 2 As shown, in some embodiments, in order to further optimize the solution, the connecting mechanism 7 includes a connecting tube 702 fixedly installed at one end of the contact head 102, and a threaded hole 701 is opened at one end of the connecting body 101. After the user inserts the connecting tube 702 into the inner wall of the threaded hole 701, the contact head 102 and the connecting body 101 can be installed. Two protrusions 8 are provided on the surface of the trapezoidal plate 3. When in use, the user slides the two protrusions 8 into the inner walls of the slots 9 opened on the inner walls of the trapezoidal groove 2 respectively, so as to increase the contact area between the trapezoidal plate 3 and the trapezoidal groove 2, thereby making it more difficult for the trapezoidal plate 3 to loosen on the inner wall of the trapezoidal groove 2.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
