Description

Technical Field

[0001] This utility model belongs to the field of steel structure building construction technology, and in particular relates to an auxiliary positioning device for assembling prefabricated steel structures. Background Technology

[0002] Prefabricated steel structures are generally constructed by pre-setting mounting holes on steel structures of different shapes. During assembly, different steel structures need to be assembled and connected to form the main body of the building. Among commonly used steel structures, H-beams are more widely used. H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Because all parts of an H-beam are arranged at right angles, H-beams have advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight.

[0003] During the steel structure assembly process, steel structures need to be assembled and erected. In particular, H-beams, which are widely used, are used as columns during the assembly process. However, H-beams cannot provide pre-support for other steel structures. Assembly deviations are prone to occur during the docking process, affecting the structural strength. Existing technology lacks suitable pre-support structures to help H-beams with auxiliary positioning and support. Utility Model Content

[0004] This utility model provides an auxiliary positioning device for assembling prefabricated steel structures, aiming to solve the problem that H-beams cannot provide pre-support for other steel structures during the assembly process, and there is a lack of suitable pre-support structures to help H-beams with auxiliary positioning and support.

[0005] This utility model is implemented as follows: an auxiliary positioning device for assembling prefabricated steel structures, comprising:

[0006] The connectors are in two sets, and the connectors are connected and engaged with the H-shaped steel column in opposite directions.

[0007] The connector includes a U-shaped locking plate and a limiting locking plate. The U-shaped locking plate has a locking area, and a pushing member is also provided in the locking area. The limiting locking plate slides on the U-shaped locking plate under the push of the pushing member. A gap is formed between the limiting locking plate and the side wall of the locking area to accommodate the flange insertion of the H-shaped steel column.

[0008] Preferably, there are two sets of limiting plates, which are respectively arranged on both sides of the pusher. Each limiting plate is provided with a slider and a flexible contact plate. The slider slides in the groove provided in the locking area. When the flange of the H-shaped steel column is inserted into the locking area, the flexible contact plate abuts against the flange of the H-shaped steel column.

[0009] Preferably, the auxiliary positioning device for assembling the prefabricated steel structure of the building further includes a fixed support platform, which includes a first support plate and a second support plate. The first support plate and the second support plate are respectively connected to different connectors. After the first support plate and the second support plate are connected, a rectangular through hole is provided at the center of the fixed support platform to accommodate the passage of the H-shaped steel column.

[0010] Preferably, the U-shaped plate is further provided with a main locking bolt. After the connecting parts are engaged with each other on the H-shaped steel column, the main locking bolt is screwed in and held against the web of the H-shaped steel column.

[0011] Preferably, a return spring is provided in the slide groove, one end of which is connected to the end of the slide groove, and the other end is connected to the slider extending into the slide groove.

[0012] Preferably, the pushing member includes a main seat, two sets of supporting blocks sliding on the main seat, and supporting studs;

[0013] The main seat has two sets of interconnected locking grooves and fastening screw holes perpendicular to the locking grooves. The two sets of abutment blocks are respectively arranged in the locking grooves and extend out of the main seat. The abutment stud is assembled in the fastening screw hole. One end of the abutment stud extends from the fastening screw hole into the connection of the two sets of locking grooves and abuts against the end of the two sets of abutment blocks. As the abutment blocks move away from each other and extend outward from the main seat during the screw-in process, the abutment blocks move away from each other and extend outward from the main seat.

[0014] Preferably, the end of the abutting stud has a frustum structure, the end of the abutting block extending out of the main seat is the abutting end, and the end of the abutting block away from the abutting end has a bevel structure and is in contact with the end of the abutting stud.

[0015] Compared with the prior art, the embodiments of this application have the following main advantages:

[0016] The auxiliary positioning device for assembling prefabricated steel structures provided by this utility model uses a U-shaped clamping plate to connect and interlock with the H-shaped steel column around its perimeter. This, combined with a limiting clamping plate and the U-shaped clamping plate, effectively secures the flanges of the H-shaped steel column without damaging it. This enhances the connection strength between the connector and the H-shaped steel column. The connector is equipped with a fixed support platform for supporting other steel structures. Before assembly, a planned assembly position is selected on the H-shaped steel column, and the auxiliary positioning device for assembling the prefabricated steel structure is assembled below this position. Before the steel structure to be assembled is fixedly connected to the H-shaped steel column, the auxiliary positioning device provides support. This pre-set support enhances the positioning accuracy during assembly and reduces deviation during the assembly process. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This utility model embodiment provides an auxiliary positioning device for assembling prefabricated steel structures, applied to H-shaped steel columns 300; such as Figures 1-7 As shown, the auxiliary positioning device for assembling prefabricated steel structures includes:

[0031] The number of connectors 100 is two sets, and the connectors 100 are respectively connected and engaged with the H-shaped steel column 300 from opposite directions in a direction parallel to the flange of the H-shaped steel column 300.

[0032] The connector 100 includes a U-shaped locking plate 110 and a limiting locking plate 120. The U-shaped locking plate 110 is provided with a locking area 111, and a pushing member 130 is also provided in the locking area 111. The limiting locking plate 120 slides on the U-shaped locking plate 110 under the pushing of the pushing member 130. A flange insertion gap for accommodating the H-shaped steel column 300 is formed between the limiting locking plate 120 and the side wall of the locking area 111.

[0033] In this embodiment, the limiting plate 120 generates a resisting force on the flange of the H-shaped steel column 300, enhancing the bonding strength between the two sets of connectors 100 and the H-shaped steel column 300. It should be noted that the width of the limiting plate 120 is smaller than the width of the locking area 111, that is, after the two sets of connectors 100 are connected, there is a gap between the limiting plates 120 on different connectors 100 to accommodate the web of the H-shaped steel column 300; the U-shaped plates 110 on different connectors 100 are fixedly connected by bolts.

[0034] In this embodiment, the U-shaped clamping plate 110 is also provided with a main locking bolt 140. After the connecting parts 100 are connected and engaged with the H-shaped steel column 300, the main locking bolt 140 is screwed in and abuts against the web of the H-shaped steel column 300. The main locking bolt 140 supplements the connection strength of the two sets of connecting parts 100 and enhances the bonding strength between the two sets of connecting parts 100 and the H-shaped steel column 300.

[0035] This application utilizes a U-shaped clamping plate 110 to engage with the H-shaped steel column 300 around its perimeter, combined with a limiting clamping plate 120 and a U-shaped clamping plate 110 to enhance the flange engagement and fixation effect of the H-shaped steel column 300, thereby strengthening the connection between the connector 100 and the H-shaped steel column 300. The connector 100 is provided with a fixed support platform 200 for supporting other steel structures. Before assembly, a planned assembly position is selected on the H-shaped steel column 300, and an auxiliary positioning device for assembling prefabricated steel structures is assembled below this position. Before the steel structure to be assembled completes the fixed connection with the H-shaped steel column 300, the auxiliary positioning device provides support force. By pre-setting support, the accuracy of the docking during the assembly process is enhanced and the offset during the assembly process is reduced.

[0036] In a preferred embodiment of this invention, the limiting plate 120 is provided with a slider 121 and a flexible contact plate 122. The slider 121 slides in the groove 112 provided in the locking area 111. When the flange of the H-shaped steel column 300 is inserted into the locking area 111, the flexible contact plate 122 abuts against the flange of the H-shaped steel column 300.

[0037] As a preferred embodiment of this embodiment, the fixed support platform 200 includes a first support plate 210 and a second support plate 220. The first support plate 210 and the second support plate 220 are respectively connected to different connectors 100. After the first support plate 210 and the second support plate 220 are connected, a rectangular through hole is provided at the center of the fixed support platform 200 to accommodate the passage of the H-shaped steel column 300.

[0038] In this embodiment, the dimensions of the first support plate 210 and the second support plate 220 are larger than the cross-sectional area of ​​the top surface of the U-shaped clamping plate 110. The first support plate 210 and the second support plate 220 are connected to the U-shaped clamping plate 110 by bolts. During the assembly process, the connector 100 can be assembled onto the H-shaped steel column 300 first, and then the support platform 200 can be assembled and fixed. A reinforcing plate is also provided below the first support plate 210 and the second support plate 220 to improve the support effect of the first support plate 210 and the second support plate 220 on the steel structure that needs to be supported. It should be noted that the position of the reinforcing plate should avoid the connector 100 and should not interfere with the connector 100.

[0039] In a preferred embodiment of this invention, the pusher 130 includes a main seat 131, two sets of abutment blocks 132 that slide on the main seat 131, and abutment studs 133; the abutment studs 133 are arranged parallel to the main locking bolts 140, and the abutment studs 133 extend into the main seat 131 after passing through the U-shaped retaining plate 110.

[0040] The main seat 131 has two sets of interconnected locking grooves and fastening screw holes perpendicular to the locking grooves. The two sets of abutment blocks 132 are respectively arranged in the locking grooves and extend out of the main seat 131. The abutment stud 133 is assembled in the fastening screw hole. One end of the abutment stud 133 extends from the fastening screw hole into the connection of the two sets of locking grooves and abuts against the end of the two sets of abutment blocks 132. As the abutment blocks 132 move away from each other and extend outward from the main seat 131 during the screwing of the abutment stud 133.

[0041] In this embodiment, the end of the supporting stud 133 is a frustum structure, the end of the supporting block 132 extending out of the main seat 131 is the supporting end, and the end of the supporting block 132 away from the supporting end is a bevel structure that contacts and connects with the end of the supporting stud 133. A stop bar is also provided at the connection port between the locking groove and the external interface, and a limiting strip is provided on the supporting block 132 to prevent the supporting block 132 from sliding out of the locking groove.

[0042] As a preferred embodiment of this example, a return spring 113 is provided in the slide groove 112. One end of the return spring 113 is connected to the end of the slide groove 112, and the other end is connected to the slider 121 that extends into the slide groove 112.

[0043] The function of the reset spring 113 is that when the limiting plate 120 is pushed by the reset spring 113, they will move closer to each other. After the holding force of the supporting block 132 is weakened, the limiting plate 120 will be pushed by the reset spring 113 towards the pushing member 130, which makes it easier to remove the connecting member 100 from the H-shaped steel column 300 during disassembly.
