Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a frame column butt joint device and an installation method. Background Art

[0002] Steel frame is a commonly used structural form for modern industrial building plants. Considering the processing capacity of process equipment and transportation factors, frame beams and columns are currently processed and manufactured in sections in the factory and transported to the project construction site. After the first-floor frame columns and the first-floor frame beams are assembled, connected and installed to form the first-floor platform, the lower columns of the first-floor frame and the upper columns of the second-floor frame are spatially connected (generally the connection node is about 1.3 meters above the frame platform beam to adapt to the ergonomic construction height) to achieve the extension of the frame columns and the subsequent erection of the second-floor frame platform beams. This process is repeated to complete the erection of all elevation platforms.

[0003] The conventional method of connecting frame columns on project sites is to use a liftable work platform to carry people. For example, Chinese patent CN221370408U discloses a construction engineering lifting platform that can be stably connected and installed, or a steel ladder is set up between the frame platform beam and the frame column to perform high-altitude construction operations. However, the above method requires high costs for machine shifts due to high-altitude operations, and the steel ladder is unstable and easy to slip, posing a safety hazard. It requires multiple people from multiple directions to repeatedly add and then dismantle, with low construction efficiency and unstable operator positions, which affects the quality of welding construction, thereby causing safety hazards to the structure and affecting the smooth implementation of construction progress, quality and safety.

[0004] Therefore, the prior art solves the above problem by using an assembled work platform. For example, Chinese patent CN211691387U discloses an assembled operating platform for steel column docking construction, in which a plurality of triangular support frames are installed on each side wall of the steel column; the triangular support frames are detachably cantilevered and inserted into steel sockets fixedly installed on the side walls of the steel column; a platform plate is placed on the overlapping plane formed by all the triangular support frames; and a circle of protective railings is detachably installed on the outer periphery of the platform plate. However, the working platform is closed on all four sides and needs to be disassembled from the top. After the final capping is completed, the working platform can only be disassembled and cannot be reused. Moreover, the installation (welding or bolting) of additional parts on the vertical surface will cause initial damage to the steel column and affect the service life of the structure. Moreover, the triangular support frame is detachable and there is a safety problem of easy loosening. Summary of the invention

[0005] Therefore, in order to solve the problems in the prior art, the present invention proposes a frame column docking device and installation method with stable structure, convenient assembly and disassembly, and low cost. The specific scheme is as follows:

[0006] A device for connecting frame columns, wherein a frame beam is vertically connected to each of the four sides of the connected frame lower column, the four frame beams are located on a horizontal plane, and the connected frame upper column is located directly above the frame lower column. The device for connecting frame columns comprises: a concave groove bottom plate, a vertical upright bar, a horizontal cross bar and an L-shaped clamping device, the concave groove bottom plate surrounds the frame lower column and is fixed to the upper surfaces of three adjacent frame beams via the clamping device, one vertical upright bar is vertically fixed to the upper surface of each corner of the concave groove bottom plate, one horizontal cross bar is welded to the top of two adjacent vertical upright bars, and a plurality of horizontal cross bars are also welded between two adjacent vertical upright bars; the concave groove bottom plate is provided with a rectangular slot hole, and the L-shaped clamping device consists of a vertical screw rod, a horizontal support rod horizontally connected to the bottom of the vertical screw rod, a roughened support plate fixed on the horizontal support rod and a nut, the top of the vertical screw rod passes through the rectangular slot hole, and the nut is screwed into the top of the vertical screw rod.

[0007] Furthermore, the width of the groove portion of the concave groove bottom plate is greater than the width of the cross-section of the lower column of the frame, and the depth of the concave groove bottom plate is greater than the height of the cross-section of the lower column of the frame.

[0008] Furthermore, the vertical poles are steel pipes or angle steels with a height of 1.2-1.5 m, and at least two of the vertical poles are vertically welded on each side of the concave groove bottom plate.

[0009] Furthermore, two adjacent horizontal cross bars located in the same plane are parallel to each other, and the distance between them is less than 1m.

[0010] Furthermore, the frame column docking device contacts the upper wing plates of the three frame beams below, and the two side edges of the upper wing plates of the three frame beams are directly opposite to two symmetrical rectangular slots.

[0011] Furthermore, the L-shaped clamping device also includes a square hole gasket, and the square hole gasket is located above the rectangular slot and below the nut.

[0012] The installation method of the above-mentioned frame column docking device is as follows: push the concave mouth of the frame column docking device to a position tangent to the outer side of the flange plate of the frame lower column, and the concave groove bottom plate is located on the upper surface of the upper wing plates of three adjacent frame beams; insert the vertical screw rod portions of multiple sets of L-shaped clamping devices into the rectangular slot holes, so that the upper surface of the roughened support plate is tangent to the lower surface of the upper wing plate of the frame beam, and respectively insert square hole gaskets into the upper ends of the vertical screw rods 11 of each set of L-shaped clamping devices extending out of the rectangular slot holes, and then tighten the nuts; unscrew the nuts, turn to remove the clamping device, push and disassemble the frame column docking device, and then install the frame column docking device for the next axis or elevation position for docking construction according to the above-mentioned operating steps, until the docking of the frame columns at all axis elevation positions of the project is completed.

[0013] The beneficial effects of the present invention are as follows: the frame column docking device is simple to manufacture and easy to construct and operate, and is suitable for high-altitude docking construction of frame columns of various specifications. It solves the current docking problems such as potential safety hazards caused by unstable ladders and easy slippage, high cost of lifting workbenches, and cumbersome disassembly and loose fixation of assembled workbenches, which may cause initial damage to steel columns. Workers can dock frame columns on the frame column docking device smoothly, safely and stably, avoiding the problem of rework of poor quality of frame column docking caused by unstable ladders or unstable lifting platforms. The frame column docking device is reusable and inexpensive, which reduces construction costs, improves construction efficiency, ensures safe high-altitude operation of operators, ensures smooth implementation of construction safety, progress and quality, and achieves the social and economic benefits of safe construction.
