Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to auxiliary support mechanisms for steel columns in prefabricated buildings. Background Technology

[0002] Auxiliary support mechanisms refer to temporary support systems established during the installation of steel columns in prefabricated building construction to ensure their stability and safety. The main function of these support mechanisms is to provide additional support before or during the installation of steel columns to prevent them from tilting, deforming, or collapsing due to external forces or their own weight.

[0003] During the construction process, when installing steel columns, the steel columns are usually placed on support rods. Then, the hydraulic rods on the support frame are activated to move the support rods upward, lifting and fixing the steel column. This facilitates alignment with other installation positions and allows for installation and fixation. However, traditional auxiliary supports for steel columns often use simple support rods for propping, which can only provide support in one direction. Under the influence of factors such as wind disturbance, hoisting impact, or vibrations from surrounding construction, the steel columns are prone to horizontal displacement or torsion, which can not only reduce installation accuracy but also lead to difficulties in connecting subsequent components, reduce installation efficiency, and in severe cases, even cause safety accidents. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: During the installation of steel columns in building construction, the steel columns are usually placed on support rods, and then the hydraulic rods on the support frame are activated to drive the support rods upward, lifting and fixing the steel column for easy installation and fixation. However, traditional auxiliary supports for steel columns mostly use simple support rods for support, which can only provide support in one direction. Under the influence of factors such as wind disturbance, hoisting impact, or vibration from surrounding construction, the steel columns are prone to horizontal displacement or torsion and other instability phenomena. This not only reduces installation accuracy but may also lead to difficulties in connecting subsequent components, reduce installation efficiency, and in severe cases, may even cause safety accidents.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary support mechanism for steel columns of prefabricated buildings, including a support frame. A hydraulic rod is fixedly installed on one side of the support frame, and a support rod is fixedly installed at the output end of the hydraulic rod. The two ends of the support rod are slidably connected to the inner walls of the two ends of the support frame. A limiting device is symmetrically arranged on one side of the support rod. The limiting device can place the steel column on the extrusion plate on the support rod, and then push the limiting rod to rotate to a certain position on the U-shaped frame through the abutment rod, thereby limiting and fixing both sides of the steel column, so that it is not easy to shake or tilt when it is supported and lifted upward, and the support is more stable.

[0006] Preferably, the limiting device includes a pressing plate and two abutment rods, wherein one end of the abutment rod is fixedly installed on one side of the pressing plate, and the other end is installed through the support rod on one side; two U-shaped frames, wherein one side of the U-shaped frame is fixedly installed on one side of the support rod; two limiting rods, wherein both ends of the limiting rods are installed through the inner walls of the U-shaped frames, and one side abuts against one side of the abutment rod; a plurality of torsion springs, wherein the inner walls of the plurality of torsion springs are respectively sleeved on the outer surfaces of the two ends of the limiting rods, and the two ends are respectively fixedly installed on the inner wall of the U-shaped frame and one side of the limiting rods; and an auxiliary mechanism, wherein the auxiliary mechanism is disposed between the pressing plate and the two limiting rods to assist the limiting rods in more firmly limiting and fixing the steel column.

[0007] The aforementioned components achieve the following effects: By setting a limiting device, during the installation of steel columns during construction, the steel column can be placed on two compression plates on the support rod. Under the weight of the steel column, the compression plates are pressed downwards, causing the abutment rod to slide downwards on one side of the support rod, with one end abutting against the limiting rod. Pushing one end of the limiting rod downwards causes it to rotate on the U-shaped frame, while the other end rotates towards the steel column, thus limiting it. At this time, the torsion spring deforms, and the compression plate drives the auxiliary mechanism to move with the limiting rod. The auxiliary limiting rod more firmly limits the steel column. Thus, during installation, activating the hydraulic rod on the support frame drives the support rod to move upwards, lifting and fixing the steel column. During the ascent, the steel column is less likely to sway or shift, making it easier to align with other installation positions for installation and fixation, improving installation efficiency and reducing safety hazards caused by support movement. Similarly, after the steel column is installed, the hydraulic rod can be activated to retract, releasing the compression of the compression plates by the steel column, thus opening the two limiting rods and releasing the limiting fixation.

[0008] Preferably, the limiting device further includes several protective covers, wherein the inner wall of the protective cover is sleeved on the outer surface of the torsion spring, and both ends are respectively fixedly installed on the inner wall of the U-shaped frame and one side of the limiting rod.

[0009] The effect achieved by the above-mentioned components is that by setting up a protective cover, the outer surface of the torsion spring can be protected, making it difficult for external impurities to get stuck in the gaps of the torsion spring, thus avoiding jamming and affecting its use.

[0010] Preferably, a circular roller is rotatably mounted on the inner wall of one end of the abutment rod, wherein the outer surface of the circular roller rolls against one side of the limiting rod.

[0011] The effect achieved by the above components is that by setting up the circular roller, the wear between one end of the abutment rod and the limiting rod can be reduced, making it easier to push them.

[0012] Preferably, a plurality of anti-slip blocks are fixedly installed on one side of the extrusion plate, and the anti-slip blocks are made of rubber.

[0013] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction on one side of the extrusion plate can be increased, making it less likely for the steel column to slip when placed on the extrusion plate, and making its positioning more stable.

[0014] Preferably, bearings are fixedly installed on the outer surfaces of both ends of the limiting rod, and the outer ring of the bearing is fixedly connected to one side of the U-shaped frame, wherein the bearing is disposed inside the torsion spring.

[0015] The effect achieved by the above components is that by setting bearings, the rotational wear between the two ends of the limit rod and the U-shaped frame can be reduced, thereby increasing the service life of both.

[0016] Preferably, the auxiliary mechanism includes an air cylinder, wherein one end of the air cylinder is mounted through the outer surface of a support rod on one side, and the inner wall of the air cylinder has symmetrically formed circular holes on one side; a piston rod, wherein one end of the piston rod is slidably mounted in the inner wall of the air cylinder, and the other end is fixedly mounted on one side of the extrusion plate after passing through one side of the inner wall of the air cylinder; a spring, wherein the inner wall of the spring is sleeved on the outer surface of one end of the piston rod, and both ends are fixedly mounted on one side of the piston rod and one side of the inner wall of the air cylinder, respectively; two airbag frames, wherein one side of the airbag frame is fixedly mounted on one side of a limiting rod; and two hoses, wherein one end of the hose is mounted through the inner wall of the air cylinder, and the other end extends through one side of the limiting rod and into the inner wall of the airbag frame.

[0017] The effect achieved by the above components is as follows: by setting an auxiliary mechanism, when the extrusion plate moves downward, it will push the piston rod to slide downward in the air cylinder, causing the spring to stretch, drawing the air inside the air cylinder into the inner wall of the hose, and then injecting it into the airbag frame, inflating several airbags on one side, filling the gap between the limiting rod and the steel column, and performing secondary limiting extrusion on the steel column to make its limiting more secure.

[0018] Preferably, the auxiliary mechanism further includes a plurality of elastic rubber blocks, wherein the elastic rubber blocks are fixedly installed in the inner wall of the circular hole.

[0019] The effect achieved by the above-mentioned components is as follows: by setting up an elastic rubber block, when the piston rod moves back and forth in the air cylinder through the round hole at one end, the elastic rubber block can protect the inner wall of the round hole, making it difficult for external dust and impurities to enter the air cylinder and avoid clogging it.

[0020] The beneficial effects of this utility model are:

[0021] By setting a limiting device, during the installation of steel columns in the construction process, the steel column can be placed on two pressing plates on the support rod. Under the weight of the steel column, the pressing plates are pressed down, causing the abutment rod to slide downward on one side of the support rod, with one end abutting against the limiting rod. Pushing one end of the limiting rod downward causes it to rotate on the U-shaped frame, while the other end rotates towards the steel column, limiting it. At this time, the torsion spring deforms, and the pressing plate drives the auxiliary mechanism to move with the limiting rod. The auxiliary limiting rod more firmly limits the steel column. During installation, the hydraulic rod on the support frame is activated to move the support rod upward, lifting and fixing the steel column. During the ascent, the steel column is less likely to sway or shift, making it easier to align with other installation positions for installation and fixation, improving installation efficiency and reducing safety hazards caused by support movement.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1-5 The auxiliary support mechanism for the prefabricated building steel column shown includes a support frame 1. A hydraulic rod 3 is fixedly installed on one side of the support frame 1, and a support rod 4 is fixedly installed at the output end of the hydraulic rod 3. The two ends of the support rod 4 are slidably connected to the inner walls of the two ends of the support frame 1. A limit device 2 is symmetrically arranged on one side of the support rod 4. The limit device 2 can place the steel column on the extrusion plate 21 on the support rod 4, and then push the limit rod 24 to rotate on the U-shaped frame 23 to a certain position through the abutment rod 22, thereby limiting and fixing both sides of the steel column, so that it is not easy to shake or tilt when it is supported and lifted upward, and the support is more stable.

[0032] Figure 1-5The limiting device 2 shown includes a pressing plate 21 and two abutting rods 22, wherein one end of the abutting rod 22 is fixedly installed on one side of the pressing plate 21, and the other end is installed through the support rod 4; two U-shaped frames 23, wherein one side of the U-shaped frame 23 is fixedly installed on one side of the support rod 4; two limiting rods 24, wherein both ends of the limiting rod 24 are installed through the inner walls of the U-shaped frame 23, and one side abuts against one side of the abutting rod 22; several torsion springs 25, wherein the inner walls of several torsion springs 25 are respectively sleeved on the outer surfaces of both ends of the limiting rod 24, and both ends are respectively fixedly installed on the inner wall of the U-shaped frame 23 and one side of the limiting rod 24; and an auxiliary mechanism 29, wherein the auxiliary mechanism 29 is disposed between the pressing plate 21 and the two limiting rods 24, for assisting the limiting rods 24 in more firmly limiting and fixing the steel column. By setting the limiting device 2, during the installation of the steel column in the construction process, the steel column can be placed on the two pressing plates 21 on the support rod 4. Under the weight of the steel column, the pressing plates 21 are pressed down, causing the abutment rod 22 to slide downward on one side of the support rod 4. One end of the abuts against the limiting rod 24, pushing one end of the limiting rod 24 downward, causing it to rotate on the U-shaped frame 23. The other end rotates towards the side of the steel column, limiting it. At this time, the torsion spring 25 deforms, and the pressing plate 21 drives the auxiliary mechanism 29 along with the limiting rod 24. The auxiliary limiting rod 24 provides a more secure limit on the steel column during operation. This allows the hydraulic rod 3 on the support frame 1 to move the support rod 4 upward during installation, lifting and fixing the steel column. This prevents the steel column from swaying or shifting during the ascent, facilitating alignment with other installation positions and enabling installation and fixation. This improves installation efficiency and reduces safety hazards caused by the movement of the support. Similarly, after the steel column is installed, the hydraulic rod 3 can be activated to retract, releasing the pressure of the steel column on the compression plate 21 and opening the two limiting rods 24 to release the limiting fixation.

[0033] Figure 1-5The limiting device 2 shown also includes several protective covers 26, the inner walls of which are fitted onto the outer surface of the torsion spring 25, and both ends are fixedly installed on the inner wall of the U-shaped frame 23 and one side of the limiting rod 24, respectively. By providing protective covers 26, the outer surface of the torsion spring 25 is protected, preventing external impurities from easily getting stuck in the gaps of the torsion spring 25 and avoiding jamming that could affect its use. A roller 27 is rotatably mounted on the inner wall of one end of the abutment rod 22, the outer surface of which rolls against one side of the limiting rod 24. By providing the roller 27, the wear between the abutment rod 22 and the limiting rod 24 is reduced, facilitating its movement. Several anti-slip blocks 28, made of rubber, are fixedly installed on one side of the extrusion plate 21. By providing the anti-slip blocks 28, the contact friction on one side of the extrusion plate 21 is increased, making it less likely for the steel column to slip on the extrusion plate 21, thus providing more stable positioning. Bearings 210 are fixedly installed on the outer surfaces of both ends of the limiting rod 24. The outer ring of the bearing 210 is fixedly connected to one side of the U-shaped frame 23, and the bearing 210 is located inside the torsion spring 25. By setting the bearings 210, the rotational wear between the two ends of the limiting rod 24 and the U-shaped frame 23 can be reduced, thereby improving the service life of both.

[0034] Figure 1-5 The auxiliary mechanism 29 shown includes an air cylinder 291, one end of which is mounted on one side of the support rod 4 through its outer surface, and symmetrically arranged circular holes 292 on one side of the inner wall of the air cylinder 291; a piston rod 293, one end of which is slidably mounted in the inner wall of the air cylinder 291, and the other end is fixedly mounted on one side of the extrusion plate 21 after passing through one side of the inner wall of the air cylinder 291; a spring 294, the inner wall of which is sleeved on the outer surface of one end of the piston rod 293, and both ends are fixedly mounted on one side of the piston rod 293 and one side of the inner wall of the air cylinder 291, respectively; two airbag frames 296, one side of which is fixedly mounted on one side of the limiting rod 24; and two hoses 295, one end of which is mounted on one side of the inner wall of the air cylinder 291 through its outer surface, and the other end of which passes through one side of the limiting rod 24 and extends into the inner wall of the airbag frame 296. By setting up the auxiliary mechanism 29, when the extrusion plate 21 moves downward, it pushes the piston rod 293 to slide downward in the air cylinder 291, causing the spring 294 to be stretched, drawing the air inside the air cylinder 291 into the inner wall of the hose 295, and then injecting it into the airbag frame 296, inflating several airbags on one side of it, filling the gap between the limiting rod 24 and the steel column, and performing secondary limiting extrusion on the steel column to make its limiting more secure.

[0035] Figure 1-5The auxiliary mechanism 29 shown also includes several elastic rubber blocks 297, which are fixedly installed in the inner wall of the circular hole 292. By setting the elastic rubber blocks 297, when one end of the piston rod 293 moves back and forth in the air cylinder 291 through the circular hole 292, the elastic rubber blocks 297 can protect the inner wall of the circular hole 292, making it difficult for external dust and impurities to enter the air cylinder 291 and prevent it from being blocked.

[0036] Working principle: During the installation of steel columns in the construction process, the steel column can be placed on the two pressing plates 21 on the support rod 4. Under the weight of the steel column, the pressing plates 21 are pressed down, causing the abutment rod 22 to slide downward on one side of the support rod 4. One end abuts against the limiting rod 24, pushing one end of the limiting rod 24 downward, causing it to rotate on the U-shaped frame 23. The other end rotates towards the side of the steel column, limiting it. At this time, the torsion spring 25 deforms, and the pressing plate 21 drives the auxiliary mechanism 29 to move with the limiting rod 24. The auxiliary limiting rod 24 limits the steel column more firmly. At the same time, when the pressing plate 21 moves downward, it pushes the piston rod 293 to slide downward in the air cylinder 291, causing the spring 294 to stretch. Air is drawn from inside the air cylinder 291 into the inner wall of the hose 295 and then injected into the airbag frame 296, inflating several airbags on one side to fill the gap between the limiting rod 24 and the steel column. This provides a secondary limiting compression to the steel column, making the limiting more secure. During installation, the hydraulic rod 3 on the support frame 1 is activated to move the support rod 4 upward, lifting and fixing the steel column. This prevents the steel column from swaying or shifting during the ascent, facilitating alignment with other installation positions and installation and fixation. This improves installation efficiency and reduces safety hazards caused by support movement. Similarly, after the steel column is installed, the hydraulic rod 3 can be activated to retract, releasing the compression of the steel column on the compression plate 21, thus opening the two limiting rods 24 and releasing the limiting fixation.
