Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of formwork construction devices, in particular to a construction column formwork construction device and process. BACKGROUND

[0002] In traditional building construction, the formwork of construction columns usually adopts wooden formwork or steel formwork. After the concrete pouring is completed, the formwork needs to be removed, and then the surface treatment is carried out. This construction method has many disadvantages, such as complicated formwork removal process, large formwork loss, long construction period, and easy generation of construction waste, which does not meet the requirements of green construction. In addition, the installation and removal of traditional formwork have high requirements for construction precision. If not handled properly, it may cause uneven surface or size deviation of the construction column, affecting the overall quality.

[0003] To solve the above problems, the formwork removal technology emerges as the times require. The formwork removal technology is a construction method that permanently combines the formwork with the structure. The formwork does not need to be removed after the concrete pouring and directly serves as a part of the construction column. Common formwork removal materials include fiber cement board, glass steel plate, etc. These materials have high strength, durability and fireproof performance, which can meet the requirements of building structures. By combining the formwork removal with the steel frame and using reliable connection methods, efficient construction of the construction column can be realized, and the overall structure and aesthetics can be improved.

[0020] As Figures 1 to 6 shown, the present application proposes a construction column disassembly-free formwork construction device, which comprises a steel frame 1, a fiber cement board 101 fixedly installed on the steel frame 1, and an installation device for installing the fiber cement board 101. The fiber cement board 101 can be erected and attached to the steel frame 1 through the installation device, which facilitates positioning and installation. The present embodiment further comprises a plurality of connecting blocks 102 fixedly installed on the steel frame 1 and having threaded holes. The fiber cement board 101 is provided with a plurality of waist-shaped holes corresponding to the threaded holes. Since the bottom of the fiber cement board 101 is in contact with the bottom plate, the fiber cement board 101 is not easy to move due to the friction between the fiber cement board 101 and the bottom plate. Therefore, the fiber cement board 101 is easy to move. Through the design of the waist-shaped hole, when the fiber cement board 101 is raised, the bolt can still pass through the waist-shaped hole and be connected with the connecting block 102, which can reduce the resistance when adjusting the fiber cement board 101.

[0021] Further, the mounting device comprises a base 2, two support plates 203 are fixedly installed on the base 2, a guide rod 210 is slidably installed on the support plate 203, the guide rod 210 can make the fiber cement board 101 move towards or away from the steel frame 1, a first connecting plate 204 is slidably installed on the guide rod 210, the first connecting plate 204 can make the fiber cement board 101 move up and down, a second connecting plate 205 is slidably installed on the first connecting plate 204, the second connecting plate 205 can make the fiber cement board 101 move in a certain range in the front and back directions, an adsorption assembly for fixing the fiber cement board 101 is rotatably installed on the second connecting plate 205, the angle of the fiber cement board 101 can be adjusted through the rotation, so that the fiber cement board 101 is parallel to the surface of the steel frame 1, and the adsorption assembly can adsorb and fix the fiber cement board 101.

[0022] As shown in Figures 6 to 9 The embodiment also comprises a first limiting assembly 4 installed on the support plate 203 to limit the guide rod 210, a second limiting assembly 5 installed on the second connecting plate 205 to limit the second connecting plate 205, and a plurality of third limiting assemblies 6 installed between the second connecting plate 205 and the adsorption assembly to limit the adsorption assembly.

When the first electric control valve 405 is closed, the hydraulic medium on both sides of the first limiting cylinder 401 cannot flow to each other, so that the position of the first limiting rod 403 is fixed, and the fiber cement board 101 cannot move towards or away from the steel frame 1.

[0026] As shown in Figures 1 to 6 In the embodiment, the adsorption assembly comprises an adsorption box 206 rotatably installed on the plurality of third limiting rods 603, the adsorption box 206 is provided with a plurality of adsorption holes 2061, a rubber head 2062 is fixedly installed in the adsorption hole 2061, a connecting hole 2063 is arranged on one side of the adsorption box 206, and the gas pump assembly 3 is fixedly installed on the base 2. The connecting hole 2063 and the gas pump assembly are connected through an air pipe. The adsorption box 206 is subjected to negative pressure by the gas pump assembly, so that the adsorption hole 2061 generates suction force on the fiber cement board 101. Under the action of air pressure, the fiber cement board 101 will be pressed on the adsorption box 206.

[0027] As shown in Figures 1 to 6As shown, the mounting device further comprises a lifting plate 201 rotatably mounted on the base 2, a first hydraulic rod 202 is rotatably mounted on the base 2, the output end of the first hydraulic rod 202 is rotatably connected with the lifting plate 201, the lifting plate 201 can be driven to rotate by controlling the extension state of the first hydraulic rod 202, and then the fiber cement board 101 is moved to a vertical state by the lifting plate 201, one end of the lifting plate 201 is fixedly provided with an extension rod 207 and rotatably provided with an internally threaded rod 208, the other end of the extension rod 207 is fixedly connected with one of the support plates 203, the other support plate 203 is fixedly connected with the bottom of the lifting plate 201, the internally threaded rod 208 is internally threaded connected with a threaded rod 209, the threaded rod 209 is fixedly connected with the support plate 203, the threaded rod 209 can be driven to lift by rotating the internally threaded rod 208, and the fiber cement board 101 of different heights can be appropriately adjusted.

[0028] It is worth noting that the bottom of one of the adsorption boxes 206 is fixedly provided with a second hydraulic rod 8, a base 801 is fixedly mounted on the output shaft of the second hydraulic rod 8, a plurality of rollers 802 are rotatably mounted on the base 801, the first connecting plate 204 can be moved up and down on the support plate 203 by driving the rollers 802 to lift by controlling the second hydraulic rod 8, and then the bottom of the fiber cement board 101 can be controlled to contact the ground, when the hole position on the fiber cement board 101 is adjusted, the bolt is first inserted, at this time the bolt is in a loose state, then the fiber cement board 101 is placed on the ground by the second hydraulic rod 8, and the bolt is tightened.

[0029] As shown, Figures 1 to 3 In this embodiment, the base 2 is fixedly provided with a reversing positioning module, which guides the base 2 when the base 2 rotates around the center of the steel frame 1. When the formwork of the structural column is constructed, the fiber cement board 101 needs to be installed on four sides, and when one side is installed, the base 2 needs to be moved when the adjacent side is installed, which will result in the need to repeat the above steps to adjust the hole position on the fiber cement board 101 when the next fiber cement board 101 is installed, which is not conducive to increasing the installation efficiency. The structural column is generally square in structure, and after the position of one side is adjusted, the device after adjustment is only needed to be rotated 90° around the center of the structural column to install the fiber cement board 101 on the next side, and the step of repositioning the hole position on the fiber cement board 101 can be reduced.

[0030] It should be noted that in order to reduce the step of repositioning the hole position on the fiber cement board 101, the center position of the fiber cement board 101 needs to correspond to the center position of the adsorption box 206 when the fiber cement board 101 is installed on the adsorption box 206 each time.

[0031] Further, the reversing positioning module comprises a sliding block 7 slidingly mounted on the base 2, a guide plate 701 slidingly mounted on the sliding block 7, a sliding groove 702 slidingly connected with the sliding block 7 arranged in the guide plate 701, the connecting line between the two ends of the sliding groove 702 and the center of the guide plate 701 being 90°, and laser lamps 703 fixedly mounted at the two ends of the guide plate 701. The base 2 is rotatably mounted with a lead screw 704, the lead screw 704 is threadedly connected with the sliding block 7, and one end of the lead screw 704 is fixedly mounted with a rotating handle 705. Since the widths of different structural columns are different and the initial position of the base 2 is different, the center of the guide plate 701 and the center of the structural column are not concentric at the beginning. At this time, the two laser lamps 703 on the two sides are started, and the intersection of the two laser beams is the circular position of the guide plate 701. At this time, the position of the guide plate 701 can be adjusted by rotating the lead screw 704, so that the center position of the guide plate 701 coincides with the center position of the structural column. Then, the position of the guide plate 701 is fixed, the guide plate 701 can be fixed by pressing a weight on the two sides of the guide plate 701, and then the base 2 is pushed to rotate along the sliding groove 702, so that the base 2 can rotate along the center position of the structural column by 90°.

[0032] On the other hand, the present application provides a construction column demoulding formwork construction process based on the above construction column demoulding formwork construction device, comprising the following steps: Step one: place the fiber cement board 101 on the adsorption box 206, and fix the fiber cement board 101 through the adsorption assembly, and then move the fiber cement board 101 to the vertical position through the first hydraulic rod 202; Step two: cancel the limiting action of the first limiting assembly 4, the second limiting assembly 5 and the third limiting assembly 6, and make the fiber cement board 101 keep a certain gap by driving the roller 802 downward through the second hydraulic rod 8; Step three: adjust the position of the fiber cement board 101, so that the position of the waist-shaped hole on the fiber cement board 101 corresponds to the threaded hole on the connecting block 102; Step four: start the limiting action of the first limiting assembly 4, the second limiting assembly 5 and the third limiting assembly 6, and make the fiber cement board 101 contact with the ground through the second hydraulic rod 8, and then fix and connect the fiber cement board 101 with the steel frame 1 through the bolts, and cancel the fixing effect of the adsorption assembly on the fiber cement board 101; Step five: coincide the center of the guide plate 701 with the center of the steel frame 1, and fix the guide plate 701; Step six: push the base 2, install the fiber cement board 101 on the adsorption assembly after the base 2 is rotated by 90°, and fix and install the other side of the steel frame 1; Step seven: after the four side fiber cement board 101 is installed, the steel frame 1 is poured with concrete.

[0033] Working principle: start the two laser lights 703, and the intersection of the two laser beams is the circular position of the guide plate 701. At this time, the position of the guide plate 701 can be adjusted by rotating the lead screw 704, so that the center position of the guide plate 701 coincides with the center position of the structural column. Then the position of the guide plate 701 is fixed. The fiber cement board 101 is placed on the adsorption box 206, and the fiber cement board 101 is fixed by the adsorption assembly. Then the fiber cement board 101 is moved to the vertical position by the first hydraulic rod 202. The second hydraulic rod 8 drives the roller 802 to lift, so that the bottom of the fiber cement board 101 is not in contact with the ground. Then the hole position on the fiber cement board 101 is adjusted. After adjustment, the bolt is inserted first. At this time, the bolt is in a loose state. Then the fiber cement board 101 is placed on the ground by the second hydraulic rod 8, and the bolt is tightened. Then push the base 2, so that the base 2 rotates along the chute 702, and then the base 2 rotates 90° along the center position of the structural column, so that the fiber cement board 101 is installed on the other side of the structural column, and the step of adjusting the hole position again is reduced, so as to improve the installation efficiency.

[0034] The above specific embodiments are only several optional embodiments of the present application.
