Description

Technical Field

[0001] The invention relates to the field of prefabricated buildings, and in particular to a column structure used for prefabricated buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, beams, columns, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings have fast construction speeds and low production costs, and are rapidly spreading around the world.

[0003] Prefabricated buildings can be divided into three main categories according to their structural materials: prefabricated concrete structures, prefabricated steel structures, and prefabricated wooden structures. Usually, prefabricated steel structures are assembled using aluminum formwork, which is composed of prefabricated large-scale internal and external aluminum formworks, floor slabs, roof panels and other panels.

[0004] The column structure of existing aluminum formwork prefabricated buildings usually vertically splices multiple groups of column structures, which are then locked using column flanges and dozens of bolt assemblies to achieve the required height. At the same time, during the later disassembly, the column structure is disassembled from top to bottom by manually holding disassembly tools and standing on the top of the column using scaffolding.

[0005] After the above structures are spliced ​​and combined, since the length of each column structure is determined, the height after splicing is often limited and cannot be adjusted arbitrarily. For this reason, construction workers usually use bricks to pad the bottom of the column structure or install multiple sets of top plates on the top to increase the height and fit. This method is prone to construction accidents and reduces the practicability of the device during the construction process. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide a column structure for prefabricated buildings to solve the technical problem that the above structure cannot be slightly adjusted in height, thereby reducing its practicality during construction.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a column structure for assembled buildings, comprising a base, a column body is arranged on the top of the base, a telescopic column is arranged inside the column body for sliding up and down movement, a straight groove is arranged in the column body, and an array of rotating grooves are evenly arranged at the straight groove, a sliding block matching the straight groove is arranged on the outer side of the telescopic column, a latch is penetrated on one side of the column body, and a rotating rod is rotatably connected at one end of the latch, a top plate is arranged on the top of the telescopic column, a driving assembly is arranged at both ends of the top plate, an output end of the driving assembly penetrates into the top plate and is connected with a bidirectional threaded rod, and an array of bidirectional threaded rods are arranged in the top plate, threaded sleeves are symmetrically arranged on the bidirectional threaded rod, and a support plate is rotatably connected to the top of the threaded sleeve through a support rod, an inner groove is arranged on the top of the support plate, a touch plate is elastically connected in the inner groove, and contacts that cooperate with each other are arranged in the touch plate and at the bottom of the inner groove.

[0008] By adopting the above technical solution, through the action of the slider on the outer side of the telescopic column and the straight groove, the telescopic column can be adjusted up and down in the column body, and the rotating motor is started to drive the support rod to lift the support plate, so as to fine-tune the tiny distance between the top of the building and the device. When the touch plate is completely flush with the support plate, the two contacts contact each other and the rotating motor stops rotating, thereby realizing automatic adjustment of the device.

[0009] The present invention is further configured such that the driving assembly is a rotary motor, and the rotary motor is used to drive the bidirectional threaded rod to rotate.

[0010] By adopting the above technical solution, the bidirectional threaded rod can be driven to rotate forward and reverse by rotating the motor, so that the support plate can be quickly disassembled at a later time.

[0011] The present invention is further configured such that the inner side of the latch is connected to the column body via a return spring, and the other end of the column body is provided with a slot that cooperates with the rotating rod.

[0012] By adopting the above technical solution, the return spring is compressed so that the rotating rod is perpendicular to the latch pin under manual action, and the return spring is reset to drive the rotating rod to be clamped into the clamping slot for limit fixing.

[0013] The present invention is further configured such that a positioning groove is provided in the rotating groove, a positioning block cooperating therewith is provided on the telescopic column, and the positioning block is vertically arranged to the positioning groove.

[0014] By adopting the above technical solution, through the cooperation between the positioning block and the positioning groove, the telescopic column can be positioned quickly to ensure the accuracy of its rotation.

[0015] The present invention is further configured such that the support rods are arranged in an X shape, and a rotating shaft is arranged at the connection between the two groups of support rods.

[0016] By adopting the above technical solution, the X-shaped setting facilitates the supporting effect of the support plate, increases the stress on the top of the support plate, and ensures its stability during the supporting process.

[0017] The present invention is further configured such that a compression spring is provided between the touch plate and the inner groove, and the compression spring is detachably provided.

[0018] By adopting the above technical solution, the compression spring can easily lift up the touch panel when not in use, and the disassembly setting can facilitate its maintenance and replacement at a later time.

[0019] The present invention is further configured such that both the column body and the telescopic column are provided with through holes for the insertion of the latch pin.

[0020] By adopting the above technical solution, the telescopic column is easily fixed in the column body by passing the pin through the through hole.

[0021] The present invention is further configured such that the top plate and the telescopic column are detachably arranged.

[0022] By adopting the above technical solution, after the disassembly work is completed at a later stage, the two can be disassembled and carried for transportation, and local maintenance can be performed on them.

[0023] The present invention is further configured such that two ends of the top plate are provided with arrays of hooks and rings for connection and installation.

[0024] By adopting the above technical solution, through the action of the hook ring, it is convenient to pull the telescopic column to a specified height by a crane, and it is also convenient for workers to install and disassemble it.

[0025] The present invention is further configured such that the rotating motor and the contact are electrically connected via a controller.

[0026] By adopting the above technical solution, it is ensured that when the two sets of contacts are in contact, the rotating motor can be powered off through the action of the controller.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention provides a straight groove and a rotating groove in the column body, and through the action of the slider outside the telescopic column and the straight groove, the telescopic column can slide up and down in the column body, and the slider is rotated and inserted into the rotating groove to limit and fix the telescopic column, so that the telescopic column can adjust the height difference up and down in the column body;

[0029] 2. The present invention provides through holes on both the column body and the telescopic column. When the telescopic column is rotated and limited on the column body, the through holes on the telescopic column and the column body correspond to each other one by one. The latch can be inserted into the through hole. The rotating rod at one end of the latch is rotated to make it perpendicular to the latch, and the latch is reset to one side under the action of the reset spring. The rotating rod is limited in the slot and in close contact with the slot, so as to fix the telescopic column. At the same time, the latch is pulled later to turn the rotating rod and the latch to be parallel, so that it can be easily taken out, which speeds up the disassembly efficiency in the later stage and reduces the workload.

[0030] 3. The present invention provides a top plate on the top of the telescopic column, and provides a support plate on the top plate. The rotating motor is started to drive the internal bidirectional threaded rod to rotate, thereby driving the support rod to lift the support plate, thereby achieving fine adjustment of the tiny distance between the top of the building and the device. Contact points that cooperate with each other are provided at the bottom of the touch plate and the inside of the inner groove. During the upward lifting process, the touch plate moves into the inner groove. When the touch plate is completely flush with the support plate, the two contacts contact each other and the rotating motor stops rotating, thereby achieving automatic adjustment of the device and accelerating its installation efficiency.

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] A column structure for a prefabricated building, such as Figure 1-Figure 6 As shown, it includes a base 1, a rotating mechanism, a folding mechanism and a fixing mechanism. The base 1 is fixed to a designated area by a bolt assembly. During the assembly of the aluminum formwork assembled building, the column body 6 is clamped in the base 1. The overall height of the column body 6 is between 1.5m-1.7m, the overall height of the telescopic column 7 is between 1.2m-1.5m, and the weight of each group of telescopic columns 7 is between 25kg-30kg. The telescopic column is pulled out of the column body 6 by the cooperation of an external crane and a hook ring 17. The slider 23 is located in the straight groove 1 8, and the telescopic column 7 is rotated by standing on the scaffold to make it snap into the rotating groove 20. The telescopic column 7 drives the slider 23 and the positioning block 24 to rotate in the rotating groove 20. Under the action of the gravity of the column body 6, the positioning block 24 slides into the positioning groove 19 to realize the positioning of the through hole 5 through which it passes. The bolt 22 penetrates the column body 6 and the telescopic column 7, and a rotating rod 4 is rotated in the through groove 3 at one end of the bolt 22. By making the rotating rod 4 perpendicular to the bolt 22, it is driven to be pulled into the card slot 2 under the action of the reset spring 21. The telescopic column 7 is fixed in a limited position so that the telescopic column 7 can be adjusted in height difference up and down in the column body 6. A top plate 8 is arranged on the top of the telescopic column 7. By starting the rotating motor 13, the four sets of bidirectional threaded rods 9 inside the telescopic column 7 are driven to rotate, thereby driving the four sets of support rods 16 to fold and lift the support plate 12. The touch plate 10 is located on the top of the support plate 12 through the action of the compression spring 11. When the touch plate 10 first contacts the top plate of the aluminum mold building, it moves into the inner groove 15. When the bottom of the touch plate 10 is in contact with the inner groove 15, the touch plate 10 is moved to the inner groove 15. 5 is provided with contacts that cooperate with each other. During the movement, when the touch plate 10 is completely flush with the support plate 12, the two contacts contact each other and the rotating motor 13 stops rotating, thereby realizing automatic adjustment of the device and accelerating its installation efficiency. If this structure is not adopted, when the rotating motor 13 drives the support plate 12 to lift up, the construction workers need to observe with their naked eyes whether the top is tightly fitted. Since the human eye cannot make a good judgment, the lifting process may result in loose fitting or excessive lifting, which is not conducive to the stable use process.

[0041] On the basis of the above structure, in this embodiment, the rotating motor 13 and the contacts are electrically connected through the controller. When the two sets of contacts are in contact with each other, the power supply of the rotating motor 13 is disconnected, which is equivalent to a control switch. The electrical connection between the contacts and the controller is a prior art for those skilled in the art, so it is not elaborated in detail.

[0042] The support rods 16 are arranged in an X shape to increase the stress between them and improve the supporting force of the device itself. At the same time, every two groups of horizontal two-way threaded rods 9 are rotatably connected to facilitate the two groups of rotating motors 13 to drive the four groups of two-way threaded rods 9 to rotate.

[0043] On the basis of the above structure, in this embodiment, a threaded sleeve 14 is arranged between the support rod 16 and the bidirectional threaded rod 9. The threaded sleeve 14 and the support rod 16 are rotatably arranged, and a limiting slider is arranged at the bottom of the threaded sleeve 14 to prevent the threaded sleeve 14 from rotating when it rotates, thereby ensuring the stability of the threaded sleeve 14 moving on the bidirectional threaded rod 9.

[0044] Exemplarily, the connection method between the hook ring 17 and the outside world can be replaced by directly pulling up the clamping plate, and is not limited to one connection method, as long as the effect of pulling the telescopic column 7 out of the column body 6 can be achieved.

[0045] On the basis of the above structure, in this embodiment, the top plate 8 and the telescopic column 7 are detachably arranged. After the disassembly work is completed at a later stage, the two can be disassembled and carried for transportation, and local maintenance can be performed on them.

[0046] In order to further improve the stability of the device itself, the length of the base 1 is greater than the length of the column body 6, and a plurality of bolt assemblies are arranged on the base 1.

[0047] When in use, the base 1 is installed in the designated area, and the sliding block 23 cooperates with the straight groove 18 to make the telescopic column 7 slide up and down in the column body 6. The sliding block 23 is inserted into the rotating groove 20 by rotating the telescopic column 7 to adjust a certain height difference. Then, the latch 22 passes through the column body 6 and the telescopic column 7 to support and fix the telescopic column 7. The rotating rod 4 at one end of the latch 22 is rotated to make it perpendicular to one end of the latch and cooperate with the slot 2 to limit the latch 22. At the same time, the telescopic column 7 is A top plate 8 is provided on the top. The rotating motor 13 is started to drive the internal bidirectional threaded rod 9 to rotate, and then the support rod 16 is driven to lift the support plate 12, so as to fine-tune the distance between the top of the building and the device. In the process of lifting upward, the touch plate 10 moves into the inner groove 15. When the touch plate 10 is completely flush with the support plate 12, the contact point at the bottom of the touch plate 10 contacts the contact point in the inner groove 15, and the rotating motor 13 stops rotating to realize automatic adjustment of it, thereby increasing the practicality of the device and accelerating the later disassembly efficiency.

[0048] The present invention creatively sets the column body 6 to be adjustable, avoiding the traditional method of manually assembling multiple groups to splice the height. In the prior art, the height is limited after the splicing and assembly, and its height cannot be slightly adjusted. In this solution, the cooperation between the slider 23 and the rotating groove 20 can adjust the length of the telescopic column 7 extending in the column body 6, and at the same time, its overall height can be fine-tuned through the support plate 12, and the automatic adjustment of the device can be achieved through the rotating motor 13, thereby accelerating its installation efficiency.

[0049] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
