Description

Technical Field

[0001] This utility model belongs to the field of prefabricated wall panel technology, and specifically relates to a connection structure between a prefabricated wall panel and a steel column. Background Technology

[0002] Wall panels are not merely decorative items; they have their own weight and bear wind loads, seismic forces, construction loads, etc. The connecting structure is the channel for force transmission, transferring the vertical load (self-weight) of the wall panel to the steel column or main structure, and the horizontal load (wind, earthquake) from the wall panel to the steel column, and then to the foundation. This prevents the wall panel from being blown off or collapsing in strong winds or earthquakes, ensuring the safety of life and property. Therefore, a connecting structure is needed to connect the prefabricated wall panels to the steel column.

[0003] Most existing connection mechanisms involve welding or bolting steel plates or reinforcing bars to steel columns on the wall panels to achieve fixed installation. While this meets the requirement of installing wall panels on steel columns, the direct welding of steel plates to steel columns prevents installation through easily disassembled structures. Dismantling requires cutting equipment (such as gas cutting or angle grinders) to cut the welds, resulting in high energy consumption, high noise, high dust, harsh working environment, and extremely low efficiency. This slows down the dismantling or modification process, making labor and machinery costs far exceed installation costs, thus increasing production costs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a connection structure for prefabricated wall panels and steel columns. By setting up insert block one and insert block two, which respectively cooperate with slot one and slot two, the wall panels and steel columns can be easily disassembled and assembled. When a wall panel is damaged, it can be removed and repaired or replaced separately without affecting the overall structure. The maintenance cost is low, the construction period is short, and it avoids the need for overall renovation due to local problems, protects the main structure, and thus greatly improves construction efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a connection structure between a prefabricated wall panel and a steel column, including a connection mechanism. The connection mechanism includes connection grooves opened on the left and right sides of the steel column. Fixing units are symmetrically arranged at the front end of the connection grooves. The wall panel is fixedly connected to the inside of the connection groove through the fixing units. The fixing unit includes a first insert block arranged on the inner side wall of the connection groove. A slot first that matches the insert block is provided on the wall panel. An installation box is provided at the front end of the connection groove. A slider is slidably arranged inside the installation box. A second insert block is arranged near one end of the connection groove. A slot second that matches the second insert block is provided inside the wall panel and the first insert block. A moving part for driving the slider to move is provided inside the installation box.

[0006] As a further improvement of this utility model, the moving part includes several springs disposed between the slider and the inner side wall of the mounting box, with one end of the spring connected to the inner side wall of the mounting box and the other end connected to the front side wall of the slider.

[0007] As a further improvement of this utility model, a pull rod is provided in the middle of the front side wall of the slider, and the pull rod extends to the outer end of the mounting box. When it is necessary to remove the wall panel from the inside of the connecting groove, first pull the pull ring. The pull ring drives the pull rod to move to the outside of the mounting box. The movement of the pull rod drives the slider to move, which in turn causes the slider compression spring to move to the end away from the wall panel. The second insert moves with the slider, so that it disengages from the connecting groove and the slot two inside the first insert. Then, the wall panel is pulled to the left and right sides of the connecting groove respectively, so that it disengages from the first insert on the inner side wall of the connecting groove, so that the wall panel can be separated from the inside of the steel column. This facilitates the disassembly of the steel column and the wall panel. When a wall panel is damaged (such as by impact, water seepage, aging), it can be removed and repaired or replaced separately without affecting the overall structure. The maintenance cost is low and the construction period is short. It avoids the need for overall renovation due to local problems, protects the main structure, and greatly improves construction efficiency.

[0008] As a further improvement of this utility model, a sliding hole adapted to the pull rod is provided on the front side wall of the mounting box.

[0009] As a further improvement of this utility model, there are four springs, which are symmetrically distributed in the form of a rectangle at the four corners. When a single spring is under force, the line of action of the force must pass precisely through its axis; otherwise, a lateral bending moment will be generated, causing the spring to twist, deform, and accelerate fatigue. The four springs are symmetrically arranged (such as at the four corners of a rectangle) to share the load. The load is evenly distributed to the four springs, and each spring experiences less force. Even if there is a slight eccentricity in the external force, the system can automatically adjust through multi-point support to avoid single-point overload, thereby improving the stability and safety of the overall structure.

[0010] As a further improvement of this utility model, an insulation layer is provided on the inner wall of the connecting groove. The thermal conductivity of steel is more than 25 times that of concrete and hundreds of times that of insulation materials. The exposed steel column or connector will act like a "radiator" to quickly conduct indoor heat to the outside (in winter) or to introduce outdoor heat into the room (in summer). The insulation layer on the inner wall of the connecting groove is equivalent to setting up a "heat insulation barrier" between the steel column and the cold / hot environment, which reduces building energy consumption (heating and cooling) and meets the goals of green building and "dual carbon".

[0011] As a further improvement of this utility model, the length of the second insert is less than the thickness of the wall panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up insert one and insert two, which cooperate with slot one and slot two respectively, it is convenient to disassemble the steel column and the prefabricated wall panel. When a wall panel is damaged (such as by impact, water seepage, aging), it can be removed and repaired or replaced separately without affecting the overall structure. The maintenance cost is low and the construction period is short, avoiding the need for overall renovation due to local problems, protecting the main structure, and greatly improving construction efficiency.

[0013] Secondly, by setting up an insulation layer, the thermal conductivity of steel is more than 25 times that of concrete and hundreds of times that of insulation materials. The exposed steel columns or connectors will act like "radiators," quickly transferring indoor heat to the outside (in winter) or introducing outdoor heat into the room (in summer). Setting up an insulation layer on the inner side wall of the connection groove is equivalent to setting up a "heat insulation barrier" between the steel column and the cold / hot environment, which reduces the building's energy consumption (heating and cooling) and meets the goals of green building and "dual carbon".

[0014] Thirdly, by setting a pull ring, a pull ring is set at one end of the pull rod located on the outside of the mounting box. The pull ring provides the operator with a direct, labor-saving, and ergonomic grip point. When adjusting the tension, aligning the position, or switching gears, the operator can directly hook the pull ring with their hand or a tool (such as a wrench) to pull.

[0015] Fourth, by setting multiple springs, when a single spring is under force, the line of action of the force must pass precisely through its axis; otherwise, a lateral bending moment will be generated, causing the spring to twist, deform, and accelerate fatigue. The four springs are arranged symmetrically (such as the four corners of a rectangle) to share the load. The load is evenly distributed across the four springs, and each spring experiences less force. Even if there is a slight eccentricity in the external force, the system can automatically adjust through multi-point support to avoid single-point overload, thereby improving the stability and safety of the overall structure.

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figure 3, a connection structure between a prefabricated wall panel 203 and a steel column 204 is provided. The connection mechanism includes connecting grooves 101 on the left and right sides of the steel column 204. A fixing unit is symmetrically arranged at the front end of the connecting groove 101. The wall panel 203 is fixedly connected to the inside of the connecting groove 101 through the fixing unit. The fixing unit includes a first insert 102 disposed on the inner wall of the connecting groove 101. A slot 103 adapted to the insert is provided on the wall panel 203. A mounting box 104 is provided at the front end of the connecting groove 101. A slider 105 is slidably disposed inside the mounting box 104. A second insert 106 is disposed near one end of the connecting groove 101. A slot 107 adapted to the second insert 106 is disposed inside the wall panel 203 and the first insert 102. A moving part for driving the slider 105 to move is disposed inside the mounting box 104. The moving part includes several... A dry spring 108 is provided, with one end connected to the inner wall of the mounting box 104 and the other end connected to the front wall of the slider 105. A pull rod 109 is provided in the middle of the front wall of the slider 105, extending to the outer end of the mounting box 104. When the wall panel 203 needs to be removed from the inside of the connecting groove 101, the pull ring 202 is pulled first. The pull ring 202 drives the pull rod 109 to move to the outside of the mounting box 104. The movement of the pull rod 109 drives the slider 105 to move, thereby causing the slider 105 to compress the spring 108 and move to the end away from the wall panel 203. The second insert 106 moves with the slider 105, causing it to disengage from the slot 107 inside the connecting groove 101 and the first insert 102. Then, the wall panel 203 is pulled to the left and right sides of the connecting groove 101 respectively, causing it to disengage from the first insert 102 on the inner wall of the connecting groove 101, so as to remove the wall panel 203 from the inside of the steel column 204.

[0021] When it is necessary to install the prefabricated wall panel 203 into the connecting groove 101 on the steel column 204, first push the wall panel 203 into the connecting groove 101 of the steel column 204 from the outside to the inside. During the movement, slightly pull the pull ring 202 forward, so that the pull ring 202 drives the second insert block 106 to move through the pull rod 109 and the slider 105. This causes one end of the second insert block 106 to abut against the side wall of the wall panel 203, and the first insert block 102 on the connecting groove 101 is inserted into the first slot 103 on the wall panel 203. Continue to push the wall panel 203 into the connecting groove 101 of the steel column 204 until the second insert block 106 is inserted into the second slot 107 provided inside the wall panel 203 and the first insert block 102 under the action of the spring 108, thereby fixing the wall panel 203.

[0022] like Figure 2 , 3 As shown, the front side wall of the mounting box 104 is provided with a sliding hole that matches the pull rod 109, and the side wall of the connecting groove 101 is provided with a through hole that matches the insert block 106.

[0023] like Figure 2 , 3 As shown, there are four springs 108. When a single spring 108 is under force, the line of action of the force must pass precisely through its axis; otherwise, a lateral bending moment will be generated, causing the spring 108 to twist, deform, and accelerate fatigue. The four springs 108 are arranged symmetrically (such as at the four corners of a rectangle) to share the load. The load is evenly distributed across the four springs 108, and each spring 108 experiences less force. Even if there is a slight eccentricity in the external force, the system can automatically adjust through multi-point support to avoid single-point overload, thereby improving the stability and safety of the overall structure.

[0024] like Figure 1 , 4 As shown, the inner wall of the connecting groove 101 is provided with an insulation layer 201. The thermal conductivity of steel is more than 25 times that of concrete and hundreds of times that of insulation materials. The exposed steel column 204 or connector will act like a "radiator" to quickly conduct indoor heat to the outside (in winter) or to introduce outdoor heat into the room (in summer). The insulation layer 201 on the inner wall of the connecting groove 101 is equivalent to setting up a "heat insulation barrier" between the steel column 204 and the cold / hot environment, which reduces building energy consumption (heating and cooling) and meets the goals of green building and "dual carbon".

[0025] like Figure 3 As shown, the length of the second insert 106 is less than the thickness of the wall panel 203.

[0026] In use, when it is necessary to remove the wall panel 203 from the inside of the connecting groove 101, first pull the pull ring 202. The pull ring 202 drives the pull rod 109 to move to the outside of the mounting box 104. The movement of the pull rod 109 drives the slider 105 to move, which in turn causes the slider 105 to compress the spring 108 and move to the end away from the wall panel 203. The second insert 106 moves with the slider 105, so that it is disengaged from the slot 107 inside the connecting groove 101 and the first insert 102. Then, pull the wall panel 203 to the left and right sides of the connecting groove 101 respectively, so that it is disengaged from the first insert 102 on the inner side wall of the connecting groove 101, so as to remove the wall panel 203 from the inside of the steel column 204.

[0027] When it is necessary to install the prefabricated wall panel 203 into the connecting groove 101 on the steel column 204, first push the wall panel 203 into the connecting groove 101 of the steel column 204 from the outside to the inside. During the movement, slightly pull the pull ring 202 forward, so that the pull ring 202 drives the second insert 106 to move through the pull rod 109 and the slider 105, so that one end of the second insert 106 abuts against the side wall of the wall panel 203, and the first insert 102 on the connecting groove 101 is inserted into the slot 103 on the wall panel 203, and continue to push it into the steel column. The wall panel 203 is pushed inside the connecting groove 101 of 204 until the second insert 106 is inserted into the slot 107 inside the wall panel 203 and the first insert 102 under the action of the spring 108, thereby fixing the wall panel 203 and facilitating the disassembly of the steel column 204 and the wall panel 203. When a wall panel 203 is damaged (such as by impact, water seepage, aging), it can be removed and repaired or replaced separately without affecting the overall structure. The maintenance cost is low and the construction period is short, avoiding the need for overall renovation due to local problems, protecting the main structure, and greatly improving construction efficiency.

[0028] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a pull ring 202 is provided at one end of the pull rod 109 located on the outside of the mounting box 104. The pull ring 202 provides the operator with a direct, effortless, and ergonomic gripping point. When adjusting the tension, aligning the position, or switching gears, the operator can directly hook the pull ring 202 with their hand or a tool (such as a wrench) to pull it.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
