[0002] The frame structure is a building structure system composed of beams and columns to bear vertical and lateral loads. It is widely used in residential buildings, office buildings, shopping malls, hotels and multi-storey industrial plants. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on site through reliable connection methods.

Since there is no mounting hole positioning mechanism, it is difficult to flexibly correspond the mounting holes, which is prone to frequent misalignment and reduces the installation efficiency. Therefore, we propose a prefabricated column of an assembled building frame structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] A prefabricated column of an assembled building frame structure comprises a first prefabricated column 1, a mounting seat 3 mounted on the bottom of the first prefabricated column 1, and a second prefabricated column 2 arranged above the first prefabricated column 1.

[0026] In this embodiment: the existing device {publication (announcement) number}: CN213572649U discloses a prefabricated column of an assembled building frame structure. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above-mentioned design is in use, although the prefabricated column has a connecting plate a and a connecting plate b and is screwed and connected by screws and nuts, which makes the installation between the prefabricated column a and the prefabricated column b convenient, but the prefabricated column b is hoisted on the prefabricated column a by the hoisting equipment, the two groups of mounting holes need to be matched before they can be connected and fixed by bolts and nuts. During the hoisting process, the swing amplitude is large. Since there is no mounting hole positioning mechanism, it is difficult to flexibly match the mounting holes, and frequent misalignment is prone to occur, which reduces the installation efficiency." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a positioning connection component 4 is added to the present application document.

[0027] More specifically:

[0028] like Figure 1-Figure 4 As shown:

[0029] A positioning connection assembly 4 is installed between the first prefabricated column 1 and the second prefabricated column 2, and the positioning connection assembly 4 includes a frame-shaped steel plate 1 401 fixedly installed at the top end of the first prefabricated column 1, a frame-shaped steel plate 2 402 fixedly installed at the bottom end of the second prefabricated column 2, and adjustment screws 405 arranged on the four sides of the frame-shaped steel plate 1 401, and steel bar holes are opened at the four corners of the frame-shaped steel plate 2 402 and the frame-shaped steel plate 1 401;

[0030] A positioning plate 406 is provided on the surface of the adjusting screw 405. The positioning plate 406 is threadedly connected to the surface of the adjusting screw 405 through a thread groove. A symmetrically arranged limiting guide rod 408 is fixed to one side of the positioning plate 406.

[0031] Locking bolts 403 are arranged in the steel bar holes at the four corners of the frame steel plate 1 401. The locking bolts 403 pass through the steel bar holes of the frame steel plate 1 401 and the frame steel plate 2 402 in sequence, and are threadedly connected with nuts 404 arranged at the four corners of the top of the frame steel plate 2 402. The locking bolts 403 and the nuts 404 are used to connect and fix the frame steel plate 1 401 and the frame steel plate 2 402. A limiting hole compatible with the limiting guide rod 408 is opened on the surface of the frame steel plate 1 401, and the limiting guide rod 408 and the frame steel plate 1 401 are slidably connected through this limiting hole.

[0032] In this embodiment: when the prefabricated columns of the assembled building frame structure are used, first, the first prefabricated column 1 is installed at a specified position on the ground through the mounting seat 3 by means of a lifting device (not shown in the figure) (this installation method can be fixedly installed by bolts), and then the second prefabricated column 2 is hoisted by the lifting device again and installed on the first prefabricated column 1. During this process, when the frame-shaped steel plate 2 402 on the second prefabricated column 2 is placed on the frame-shaped steel plate 1 401 of the first prefabricated column 1, the positioning plate 406 is driven to move by rotating the adjusting screw 405, and the positioning plate 406 drives the limiting guide rod 408 to move. By setting the limiting guide rod 408, the positioning plate 406 can be limited, so that the positioning plate 406 is more stable during the movement process, and as the installation bar 411 moves, the frame plate 402 on the second prefabricated column 2 is pushed. The second frame steel plate 402 moves relative to the protruding portion of the frame steel plate 1 401 until the second frame steel plate 402 corresponds to the side edge of the frame steel plate 1 401. At this time, the steel bar holes on the frame steel plates 1 401 and the second frame steel plates 402 are in a corresponding state. Then, the locking bolts 403 pass through the steel bar holes of the frame steel plates 1 401 and the second frame steel plates 402 in turn, and are threadedly connected with the nuts 404 to connect and fix the frame steel plates 1 401 and the second frame steel plates 402, thereby realizing the fixed installation of the second prefabricated column 2 and the first prefabricated column 1. Through this operation, a positioning operation is performed, and the steel bar holes of the frame steel plates 1 401 and the second frame steel plates 402 can be flexibly matched quickly, so as to avoid the steel bar holes being frequently in a micro-misaligned state when the second prefabricated column 2 falls on the first prefabricated column 1, thereby improving the installation efficiency and achieving a better use effect.

[0033] Going further;

[0034] In an optional embodiment, a hexagonal block 407 is welded to one end of the adjusting screw 405 .

[0035] In this embodiment, the tool wrench can be clamped on the hexagonal block 407, so that it can be easily engaged to more conveniently drive the adjusting screw 405 to rotate.

[0036] Going further;

[0037] In an optional embodiment, one end of the adjusting screw 405 is rotatably connected to an insert block 409 via a bearing, a slot matching the insert block 409 is provided on the surface of the frame-shaped steel plate 401, and the insert block 409 is inserted into the slot provided in the frame-shaped steel plate 401, and a symmetrically arranged fixing bolt 410 is threadedly connected to one side of the bottom of the frame-shaped steel plate 401 near the insert block 409, and a socket for inserting the fixing bolt 410 is provided on the lower surface of the insert block 409, and the fixing bolt 410 is screwed into the socket provided in the insert block 409.

[0038] In this embodiment: after the first prefabricated column 1 and the second prefabricated column 2 are installed, the fixing bolt 410 can be rotated to release the position lock of the plug block 409, so that the plug block 409 can be detached from the frame-shaped steel plate 401, and the positioning connection component 4 can be removed from the frame-shaped steel plate 401, so that the positioning connection component 4 can be installed on the structure where the frame-shaped steel plate 401 and the frame-shaped steel plate 2 402 are not connected to each other, thereby saving manufacturing costs and conveniently disassembling the positioning connection component 4 for better use effect.

[0039] Going further;

[0040] In an optional embodiment, the top of the positioning plate 406 is slidably connected to a mounting bar 411, a plurality of groups of equidistantly arranged springs 412 are fixed between the mounting bar 411 and the positioning plate 406, a sliding groove matching the mounting bar 411 is provided on the upper surface of the positioning plate 406, and the mounting bar 411 and the positioning plate 406 are slidably connected through the sliding groove.

[0041] In this embodiment: when the frame-shaped steel plate 402 on the second prefabricated column 2 falls on the positioning plate 406, the frame-shaped steel plate 402 squeezes the installation bar 411. At this time, the installation bar 411 compresses the spring 412, thereby achieving an impact buffering effect, preventing the frame-shaped steel plate 402 from falling on the positioning plate 406 and causing collision damage due to the impact force of the critical point, thereby further improving the use effect of the device.

[0042] The working principle and use process of the utility model: when the prefabricated columns of the assembled building frame structure are used, firstly, the first prefabricated column 1 is installed at a specified position on the ground through the mounting seat 3 by means of a lifting device (not shown in the figure) (this installation method can be fixedly installed by bolts), and then the second prefabricated column 2 is lifted by the lifting device again and installed on the first prefabricated column 1. During this process, when the frame steel plate 2 402 on the second prefabricated column 2 is placed on the frame steel plate 1 401 of the first prefabricated column 1, the adjusting screw 405 is then rotated to drive the positioning plate 406 to move, and the positioning plate 406 drives the limiting guide rod 408 to move, and the positioning screw 405 is rotated to drive the positioning plate 406 to move. By setting the limit guide rod 408, the positioning plate 406 can be limited, so that the positioning plate 406 is more stable during the movement. With the movement of the installation strip 411, the frame steel plate 402 on the second prefabricated column 2 is pushed to move relative to the extended part of the frame steel plate 401, until the frame steel plate 402 corresponds to the side edge of the frame steel plate 401. At this time, the steel bar holes on the frame steel plate 401 and the frame steel plate 402 are in a corresponding state. Then the locking bolt 403 passes through the steel bar holes of the frame steel plate 401 and the frame steel plate 402 in turn, and is threadedly connected with the nut 404 to lock the frame steel plate 401 and the frame steel plate 402. The frame-shaped steel plate 402 is connected and fixed, thereby realizing the fixed installation of the second prefabricated column 2 and the first prefabricated column 1. Through this operation, a positioning operation is performed, and the steel bar holes of the frame-shaped steel plate 401 and the frame-shaped steel plate 402 can be flexibly matched quickly, so as to avoid that when the second prefabricated column 2 falls on the first prefabricated column 1, the steel bar holes are frequently in a state of micro-misalignment, thereby improving the installation efficiency and achieving better use effect. When the frame-shaped steel plate 402 on the second prefabricated column 2 falls on the positioning plate 406, the frame-shaped steel plate 402 squeezes the installation strip 411, and at this time, the installation strip 411 compresses the spring 412, so as to have an impact buffering effect and avoid The frame-shaped steel plate 402 does not fall on the positioning plate 406 and is damaged by collision due to the impact force at the critical point, so as to further improve the use effect of the device. When the first prefabricated column 1 and the second prefabricated column 2 are installed, the fixing bolt 410 can be rotated to release the position lock of the plug block 409, so that the plug block 409 can be detached from the frame-shaped steel plate 401, and the positioning connection component 4 can be removed from the frame-shaped steel plate 401, so that the positioning connection component 4 can be installed on the structure where the frame-shaped steel plate 401 and the frame-shaped steel plate 2 are not connected to each other, thereby saving manufacturing costs and conveniently disassembling the positioning connection component 4 for better use effect.
