Description

Technical Field

[0001] The present invention relates to the technical field of steel structure engineering, and specifically to an installation and anti - detachment structure for steel structure construction columns. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings replace reinforced concrete with steel plates or sections, which have higher strength and better seismic resistance. And because components can be fabricated in factories and installed on site, the construction period is greatly reduced. Due to the recyclability of steel, construction waste can be greatly reduced, making it more environmentally friendly. Therefore, it is widely adopted by countries around the world and applied in industrial and civil buildings.

[0003] In the patent with the publication number CN211421413U, a fixed base for a steel structure column is disclosed, which includes the ground and a steel structure column. An anchor column is installed in the installation groove on the ground. A second fixing plate, a first fixing plate and the steel structure column are sleeved on the anchor column. A groove on the side wall of the second fixing plate is connected with an arc - shaped metal plate through a first spring, and the bottom end surface of the second fixing plate is connected with a rectangular metal plate through a second spring. In this utility model, a cavity is formed between the arc - shaped metal plate and the side wall of the second fixing plate. The second spring installed at the bottom end surface of the second fixing plate is used to connect multiple rectangular metal plates. The transverse seismic waves transmitted to the arc - shaped metal plate are diffused and reduced in the cavity. The longitudinal seismic waves transmitted to the rectangular metal plates are gradually reduced. The reduced seismic waves are respectively transmitted to the cavity of the second fixing plate through the first through - hole and the second through - hole, and the seismic waves are further diffused and reduced, thereby reducing the overall shaking degree of the steel structure column and protecting the steel structure column.

[0004] In this patent, springs are used to achieve the purpose of energy absorption. In the case of long - term or frequent use, the performance of the springs may decline, thus affecting their anti - detachment effect. In some special environments or conditions, such as extreme temperature, humidity or corrosive environments, the performance of the springs may be affected. When the springs cannot play the role of energy absorption, this device only fixes the steel structure column through traditional bolts. The fixation is easily affected, and the anti - detachment effect of a single bolt is poor. Therefore, the reduction of the spring performance leads to the reduction of its anti - detachment effect.

[0005] When installing the steel structure column in this device, only traditional anchor columns are used for position fixation. During installation, it also needs to be moved to the pre - poured base with bolts by hoisting, and after alignment, nuts are sleeved. The crane needs to cooperate all the time, otherwise the column is very easy to deviate sideways and cause the screw to deform, and it is also very dangerous. Therefore, the installation efficiency is low.

[0006] In the prior art, the fixation and anti - detachment of columns usually rely on hoisting and bolt connection, but these methods have problems such as instability, complex operation or long time - consuming. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a steel structure construction column installation and anti - detachment structure, which solves the problems that the fixation and anti - detachment of columns usually rely on hoisting and bolt connection, and these methods are unstable, complex in operation or time - consuming.

[0014] Preferably, pressure plates are fixedly connected to both the front and rear ends of the transverse intermediate plate. A fitting groove is formed at the upper end of the pressure plate. An auxiliary traction plate is provided at one end of the pressure plate away from the transverse intermediate plate. The auxiliary traction plate is Z-shaped. A fitting convex plate is fixedly connected below the upper side wall of the auxiliary traction plate. The fitting convex plate is adapted to the fitting groove. A connecting bolt II is fixedly connected to the lower inner wall of the fitting groove. The upper end of the connecting bolt II sequentially penetrates through the fitting convex plate and the upper side wall of the auxiliary traction plate and is connected to the locking mechanism.

[0015] Preferably, the lower end of the auxiliary traction plate does not contact the upper end of the top support plate. The distance between the left and right limiting plates and the left and right side walls of the auxiliary traction plate is less than the length of the side connecting bolt.

A number of auxiliary connecting grooves are formed at the lower ends of the longitudinal structural plate and the transverse intermediate plate. The auxiliary connecting grooves are adapted to the auxiliary plates.

[0017] Preferably, a butt plate is provided at the lower end of the pressure plate. The butt plate is L-shaped.

[0019] Preferably, a splicing frame is provided at the upper end of the steel structure column. The splicing frame is adapted to the upper end of the steel structure column. The upper end of the steel structure column extends into the splicing frame. A partition is provided inside the splicing frame. The partition is located above the steel structure column. A number of splicing connection holes are provided on the splicing frame.

[0020] Working principle: When in use, use a crane to move the steel structure column to the inside of the limit support frame. When the steel structure column moves downward, place the two abutment plates under the pressure plates on the front and rear sides. As the pressure plates and the steel structure column move downward, the abutment plates are pushed into the limit support frame. When the steel structure column and the limit support frame are matched, the abutment plates fit tightly together, thereby further ensuring the stability of the steel structure column when it is not fully fixed. At the same time, the auxiliary plate and the auxiliary connecting groove are used in conjunction with the limit support frame, so that the limit support frame can be used to limit the steel structure column, and the side connecting bolts can be quickly passed through the limit support frame and the steel structure column, thereby effectively avoiding the steel structure The structural column slides off the limit support frame, ensuring that there is no need for continuous lifting operation of a crane when installing the steel structure column. The position of the steel structure column is limited by the cooperation of the locking mechanism and the side connecting bolts. A locking plate is provided in the locking mechanism of this device. When the device is reinforced by using the auxiliary locking nut, the elastic plate on the inside of the anti-slip plate is squeezed to extend into the threaded groove on the bolt, thereby effectively avoiding the problem of the main locking nut falling off during the use of the device. The matching convex plate on the auxiliary traction plate is matched with the matching groove, and the connecting bolts 1 and 2 are matched with the locking mechanism, and then the auxiliary traction plate is used to apply a certain force to the pressure plate and the steel structure column, thereby further ensuring the stability of the steel structure column.

[0021] The present invention provides a structure for installing and preventing columns from falling off during steel structure construction. It has the following beneficial effects:

[0022] 1. The present invention adapts the limit support frame to the steel structure column. When the steel structure column is installed, the lower end of the steel structure column is directly inserted into the limit support frame. At the same time, the auxiliary plate and the auxiliary connecting groove are used in conjunction with the limit support frame. The limit support frame can be used to achieve the limiting effect on the steel structure column. At the same time, the side connecting bolts are quickly passed through the limit support frame and the steel structure column, thereby effectively preventing the steel structure column from slipping from the limit support frame, ensuring that no continuous lifting operation of a crane is required when the steel structure column is installed, and at the same time, it can solve the problem that the existing steel structure column is directly connected to the anchor column and easily causes damage to the anchor column.

[0023] 2. In the present invention, an abutment plate and an abutment plate are arranged between the horizontal middle plate and the horizontal middle frame. When the steel structure column is matched with the limit support frame, the abutment plate and the abutment plate are tightly fitted together, thereby further ensuring the stability of the steel structure column when it is not completely fixed. The position of the steel structure column is fixed by the cooperation of the horizontally arranged side connecting bolts and the locking mechanism. An auxiliary traction plate is provided between the pressure plate and the top support plate to further ensure the stability of the steel structure column.

[0024] 3. A retaining piece is provided in the locking mechanism of the present invention. When using the auxiliary locking nut to reinforce the device, the elastic piece inside the retaining piece is extruded and extends into the thread groove on the bolt, effectively avoiding the problem of the column locking nut falling off during the use of the device. Moreover, the distance between the left and right limiting plates and the left and right side walls of the auxiliary traction plate is less than the length of the side connection bolt, ensuring that even when the main locking nut and the auxiliary locking nut connected to the horizontally arranged side connection bolt both fall off, the side connection bolt will still not fall off and still plays the role of limiting the steel structure column, thereby ensuring the safety and stability of the use of the steel structure column.

[0043] The locking mechanism 22 includes a main locking nut 26, a spring washer 25, a sub-locking nut 28, and a retaining piece 27. The main locking nut 26, the spring washer 25, the sub-locking nut 28, and the retaining piece 27 are all sleeved on the side connection bolt 16. The main locking nut 26 and the sub-locking nut 28 are both threadedly connected to the side connection bolt 16. The spring washer 25 is located between the main locking nut 26 and the outer side wall of the longitudinal limit frame 501.

[0044] The retaining piece 27 is annular. A plurality of elastic pieces 29 are fixedly connected to the inner side wall of the retaining piece 27. One end of the elastic piece 29 away from the retaining piece 27 is inclined towards the sub-locking nut 28. The retaining piece 27 is provided in the locking mechanism 22 of the device. When the device is strengthened by using the sub-locking nut 28, the elastic pieces 29 inside the retaining piece 27 are squeezed to extend into the thread grooves on the bolt, thereby effectively avoiding the problem of the main locking nut 26 falling off during the use of the device;

Connecting bolts I 11 are fixedly connected to both the front and rear sides of the upper surface of the top support plate 4. The upper ends of the connecting bolts I 11 penetrate the lower side wall of the auxiliary traction plate 23 and are connected to the locking mechanism 22. During use, the fitting convex plate 24 on the auxiliary traction plate 23 is fitted with the fitting groove 20, and through the cooperation of the connecting bolt I 11 and the connecting bolt II 21 with the locking mechanism 22, a certain acting force is applied to the pressing plate 19 and the steel structure column 12 through the auxiliary traction plate 23, further ensuring the stability of the steel structure column 12;

During use, during the downward movement of the steel structure column 12, the two butt plates 18 are placed under the pressing plates 19 on the front and rear sides. As the pressing plates 19 and the steel structure column 12 move downward, the butt plate 18 is pushed and extruded into the limit support frame 5. When the steel structure column 12 cooperates with the limit support frame 5, the butt plate 18 and the butt plate 10 are closely fitted, thereby further ensuring the stability of the steel structure column 12 when it is not fully fixed;
