Description

Technical Field

[0001] The utility model relates to the field of assembled environmentally friendly building wall formwork, in particular to an assembled environmentally friendly building wall formwork. Background Art

[0002] The building formwork is a building component, mainly used in floor construction. It is suitable for large-span and large-load space construction. When installed on the wall, self-tapping screws and bolts are often used to drive into the wall for quick fixation.

[0003] When laying the building formwork, the main purpose is to reduce displacement and solve its damage and deformation problems. Therefore, after the building formwork enters the construction site, relevant inspections and cleaning should be carried out. If unqualified building formwork is found, it should be removed. For some severely damaged building formwork, it should be replaced immediately to ensure normal construction.

[0004] When simple bolts and screws are used for fixing, certain damage will be caused to the bearing wall. When the wall is dismantled and replaced and readjusted and installed under the above circumstances, the damage to the wall needs to be repaired again before the formwork can be positioned and installed again, such as filling the seams with cement and grinding it flat. In this case, the process is relatively complicated and tedious. For this purpose, an assembled environmentally friendly building wall formwork is provided. Utility Model Content

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] Combined with Figure 1 , Attachment Figure 3 In order to solve the above technical problems, the technical solution provided by the utility model is: an assembled environmentally friendly building wall formwork, including a building formwork 1, a positioning through hole 19 is connected to the building formwork 1, a transmission shaft 3 is connected to the building formwork 1, the transmission shaft 3 passes through the positioning through hole 19, the top of the transmission shaft 3 is connected to an end plate 6, and the top of the end plate 6 is connected to a cross adjustment groove 7 matched with the transmission shaft 3, so that the fixed connection device of the formwork can be adjusted and controlled by tools such as a screwdriver, and the transmission shaft 3 is connected to a threaded column 4 above the positioning through hole 19, and a fixing nut 5 matched with the building formwork 1 is connected to the threaded column.

[0024] By rotating the fixing nut 5 on the threaded column 4, the fixing nut 5 is pressed against the top surface of the building module connection end, and the transmission shaft 3 is fixed in the upper and lower positions in the positioning through hole 19, so that the building formwork 1 is fixed on the wall accordingly. Figure 1 This is the main manifestation of the formwork fastening method, and specifically describes the appearance of the connecting and fixing ends of the building wall formwork, which are set on each connecting and fixing end of the formwork. The overall macroscopic morphology of the formwork is not the focus of this application, and is almost the same as the prior art, so no further description will be given here.

[0025] Embodiment 2

[0026] Combined with Figure 1-4A fixed block 2 is connected to the bottom of the building formwork 1, and an adjusting cavity 8 is connected to the center of the fixed block 2. The fixed block 2 is rotatably connected to a support shaft 9 in the adjusting cavity 8. The bottom end of the transmission shaft 3 extends into the adjusting cavity 8 and is commonly connected to the support shaft 9 with a worm gear transmission mechanism 10. The fixed block 2 is located on both sides of the adjusting cavity 8 and is connected to telescopic cavities 11. Both ends of the support shaft 9 extend into the telescopic cavity 11 and are connected to threaded rods 12. Fastening blocks 16 are slidably connected to both ends of the fixed block 2. A screw sleeve 13 is commonly connected between the fastening block 16 and the threaded rod 12. The fixed block 2 is located on one side of the telescopic cavity 11 and is connected to a limiting slide groove 15. The screw sleeve 1 A slide bar 14 is connected to one side of the telescopic cavity 11 and cooperates with the limit slide groove 15. The limit slide groove 15 and the slide bar 14 cooperate with each other to provide a limit function for the fastening block 16 and the screw sleeve 13 to move in the telescopic cavity 11. The fastening block 16 is located at the upper and lower ends of the telescopic cavity 11 away from the adjusting cavity 8 and is connected with a clearance groove 18. The upper and lower sides of the fastening block 16 are connected with a plurality of cylindrical contacts 17 located in the clearance groove 18, which are used to form contact with the upper and lower walls of the inner groove of the wall. When the fastening block 16 moves in the inner groove of the wall, the circular contacts can reduce the movement resistance. The end of the fastening block 16 away from the adjusting cavity 8 is connected with a rubber pad 20, which is used to make the side of the fastening block 16 more tightly in contact with the inner groove wall of the wall.

[0027] By rotating the transmission shaft 3, under the action of the worm gear transmission mechanism 10, and further rotating the support shaft 9, the threaded rods 12 at both ends are rotated, and the thread directions of the threaded rods 12 at both ends should be set in opposite directions. Under the limiting effect of the slider and the limiting slide groove 15 and the cooperation of the screw sleeve 13 matching the thread structure of the threaded rod 12, the fastening block 16 extends from the telescopic cavity 11 at both ends of the fixing block 2 and enters into the end of the inner groove of the wall to fix the building formwork 1.

[0028] When the utility model is implemented in practice, when the assembled building wall formwork is used to fix it on the wall, it is necessary to open an inner groove that matches the fixing block 2 in the wall in advance. Due to the unified installation and the use of a unified formwork style, it is convenient for later disassembly and replacement, and the wall grooving process is not cumbersome relative to the entire process. The fixing mechanism of the formwork is carried on the corresponding position of the building formwork 1. Macroscopically speaking, it can be considered as an integral part. During installation, the fixing block 2 is correspondingly inserted into the inner groove of the wall. After being inserted, the two sides of the fixing block 2 are theoretically in contact with the wall. In fact, it does not matter if a little gap is left. There is enough and suitable space between the two ends of the fixing block 2 and the inner groove wall of the wall. The inner space of the module is formed by rotating the transmission shaft 3 using a screwdriver or other tool. Under the action of a series of transmission and limiting structural components, the fastening blocks 16 at both ends of the fixing block 2 extend outward and are tightly inserted into the above-mentioned inner space. The ends of the cylindrical contacts 17 at the upper and lower ends are tightly in contact with the inner groove wall, i.e., the wall, thereby fixing the lower part of the module. As for the fixing of the upper part, in the subsequent process, the fixing nut 5 on the transmission shaft 3 is rotated, moved downward and tightly fitted on the upper surface of the connecting end of the building formwork 1. When disassembling, the direction operation can be performed. After disassembly, the inner groove of the wall and other structures will not be damaged, which is convenient for the next replacement of the building wall formwork to be installed again.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
