Description

Technical Field

[0001] The utility model relates to the technical field of steel column splicing and installation, and more particularly to the technical field of a detachable and reusable device for steel column splicing and installation. Background Art

[0002] The column components of steel structure buildings are generally long. Since they are too long to be transported, they usually need to be divided into several sections at the processing plant and then transported to the site for installation and splicing. The vertical splicing and installation of steel columns is widely used.

[0003] The current mainstream splicing method involves adding lugs to the four sides of the steel column joints during fabrication. Each lug is equipped with two to three bolt holes. During on-site installation, the upper and lower columns are temporarily secured with bolts using the lugs provided, and then adjusted for positioning. After securing, the joints are welded. After welding, the lugs are cut and polished to a smooth surface. For a typical H-shaped steel column, for example, each joint requires eight to twelve lugs and four to six connecting plates.

[0004] Traditional methods require pre-installed lugs for the joints, which are then cut away and polished to restore the original appearance of the steel column. This wastes material and increases labor costs for making and cutting the lugs. Furthermore, flame-cutting the lugs at the joints can easily deform the steel column, affecting its verticality. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned technical problems by providing a removable and reusable device for splicing and installing steel columns. This reusable device provides stable support for the upper and lower steel columns to be spliced ​​during installation and allows for proper adjustment of the column positions to ensure accurate alignment of the joints. Once the steel column connection and welding are complete, the device can be removed and reused for the next column.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] The utility model provides a detachable and reusable device for splicing and installing steel columns, comprising an upper hoop arranged on the outer wall of the upper steel column to be spliced, a lower hoop arranged on the outer wall of the lower steel column to be spliced, and a connecting rod assembly slidably connected between the upper hoop and the lower hoop, and the connecting rod assembly is locked on the upper hoop and the lower hoop by a locking assembly.

[0008] In one embodiment, the upper hoop and the lower hoop have the same structure and are both rectangular hoop with adjustable size.

[0009] Specifically, the key point of this solution is that the four clamps enclose a rectangular hoop of variable size and lock the size to hold the steel column tightly, and the rectangular hoop can be connected and locked to temporarily fix the upper and lower steel columns.

[0010] In one embodiment, each rectangular hoop includes four L-shaped clamps, each L-shaped clamp including a long steel plate and a short steel plate that are orthogonal to each other;

[0011] A first jack seat is provided on the outer side of the long steel plate near one end of the short steel plate, and a first vertical through hole is provided on the first jack seat;

[0012] A second jack seat is provided on the outer side of the short steel plate near one end of the long steel plate, a second horizontal through hole is provided on the inner side of the second jack seat, and a second vertical through hole is provided on the outer side of the second jack seat;

[0013] A third jack seat is provided on the outer side of the short steel plate away from one end of the long steel plate, and a first transverse insertion hole is provided on the third jack seat, and the position of the first transverse insertion hole corresponds to the position of the second vertical insertion hole;

[0014] The long steel plate of one of the L-shaped clamps passes through the first transverse insertion hole and the second transverse insertion hole of the adjacent other L-shaped clamp in sequence and is locked by a transverse bolt assembly.

[0015] In one embodiment, the connecting rod assembly includes eight connecting rods divided into four groups, and two connecting rods in each group pass through the first vertical insertion hole and the second vertical insertion hole on a corresponding L-shaped clamp and are locked by a vertical bolt assembly.

[0016] The present solution is simplified to the maximum extent possible into several standard components (L-shaped clamps, connecting rods), whose specifications and parameters can be the same and matched with each other to achieve the purpose of mutual replacement.

[0017] Specifically, when installing the steel column vertically, use two hoops on each of the lower and upper steel columns. For the upper end of the lower steel column (near the place to be spliced ​​and welded), use two lower hoops as a group to surround the lower steel column and lock it (such as Figure 2 As shown in the figure, the installation method of the two upper hoops on the upper steel column is the same as the installation method of the two lower hoops on the lower steel column; the upper hoops and the lower hoops have the same structure, both of which are rectangular hoops with adjustable size. Each rectangular hoops includes four L-shaped clamps. In the same rectangular hoops, the four L-shaped clamps at the same elevation are circumferentially locked to the corresponding steel column (upper steel column or lower steel column) through a transverse bolt assembly. There is a certain distance between the two adjacent rectangular hoops in the vertical height to make the connection more stable.

[0018] When the upper steel column is hoisted to the top of the lower steel column, after preliminary alignment, eight connecting rods are used to pass through the two upper rectangular hoops and the two lower rectangular hoops to connect them together, and the vertical bolt assembly is tightened immediately.

[0019] Installation is complete, and the entire joint, connected by eight connecting rods in four directions, is now fully integrated. The entire steel column can withstand horizontal forces from any direction at the joint. Subsequently, the joint can be welded. Once welding is complete, the upper and lower steel columns form a single unit. The locking bolts can now be released, and the device can be disassembled. The steel column splicing is now complete.

[0020] In actual application, the number of rectangular ferrules on each side of each steel column joint can be increased or decreased based on the size of the steel columns to be spliced ​​and actual needs (but at least one per side); the spacing between the rectangular ferrules at each end of the joint can also be adjusted according to actual needs. Furthermore, the actual number of connecting rods can be increased or decreased based on actual needs, such as one per side for a total of four. The actual length, size, and thickness of the vertical connecting rods can be adjusted according to actual needs (and the corresponding connecting rod holes can be adjusted accordingly).

[0021] In one embodiment, a protrusion is provided on the inner side of the long steel plate close to the short steel plate, and the height of the protrusion is the same as the thickness of the short steel plate.

[0022] Specifically, in an L-shaped clamp, there are "bumps" at the corners to accommodate the rectangular shape of the interior of the L-shaped clamp.

[0023] In one embodiment, an elastic spacer is provided on the inner side of the long steel plate close to the short steel plate, and an elastic spacer is provided on the inner side of the short steel plate close to the long steel plate.

[0024] Specifically, in the L-shaped clamp, an elastic spacer (such as rubber) can be added on the inside of the corner position that contacts the steel column to enable the hoop to better contact the steel column and increase the friction with the steel column.

[0025] In one embodiment, the contact surfaces between the connecting rod in the first vertical through hole and the connecting rod in the second vertical through hole and the vertical bolt assembly are rough surfaces or serrated surfaces.

[0026] Specifically, the contact area between the L-shaped clamp and the connecting rod at the vertical bolt assembly can be made into a rough surface or a serrated surface to increase the locking force.

[0027] In one embodiment, the cross-sectional shape of the connecting rod is one of circular, rectangular or trapezoidal, and the shapes of the first vertical through hole and the second vertical through hole are adapted to the shape of the connecting rod.

[0028] Specifically, the cross section of the connecting rod can be made into a circular cross section, a rectangular cross section, a trapezoidal cross section, etc. as required. The corresponding first vertical through hole and the second vertical through hole are made into shapes that are adapted thereto.

[0029] In one embodiment, the contact portion of the long steel plate in the first transverse through hole with the transverse bolt assembly is a rough surface or a serrated surface.

[0030] In one embodiment, the upper steel column and the lower steel column have the same shape, and the cross-sections of the upper steel column and the lower steel column are box-shaped sections or H-shaped sections.

[0031] The beneficial effects of the utility model are as follows:

[0032] 1. This utility model has a reasonable design. The device consists of a small number of standardized basic modular components, with a simple structure and easy use and maintenance. When splicing and installing steel columns, it is not necessary to weld any auxiliary components (such as lugs, etc.) to the main steel structure to achieve the purpose of temporarily stabilizing the steel column splice joints, and no damage is caused to the steel column itself.

[0033] 2. This device is detachable, reusable, and low-cost. Eight locking links provide a more stable and reliable fixation of the steel column. The principle is simple, the operation is easy, and the installation is convenient. The basic structural components are few and standardized, making maintenance and replacement easy.
