DETAILED DESCRIPTION

[0034] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below in conjunction with the drawings and specific embodiments.

[0035] It should be noted that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the solutions of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0036] It should also be noted that the terms "comprise", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0037] As shown in Figure 1 , Figure 2 and Figure 7 , the present application provides an auxiliary device for butt joint positioning of a steel structure, comprising:

[0038] an H-shaped vertical steel 80;

[0039] a frame 10, two frames 10 being symmetrically arranged on both sides of the H-shaped vertical steel 80;

[0040] The locking assembly 30 is arranged at the bottom of the frame 10, so that when the locking assembly 30 is in the locked state, the two frames 10 together form a positioning frame with an opening at the top and the side away from the H-shaped vertical steel 80, and two interconnected positioning cavities are formed inside the positioning frame, the width of which decreases successively along the direction away from the H-shaped vertical steel 80. At the same time, the ends of the two frames 10 close to the H-shaped vertical steel 80 are respectively tightly attached to the two sides of the web of the H-shaped vertical steel 80, so that the locking assembly 30 and the ends of the frames 10 close to the H-shaped vertical steel 80 together form a clamping mechanism for preliminarily fixing the auxiliary device on the H-shaped vertical steel 80;

[0041] The fixing plate 54 is connected to the frame 10 at one end close to the H-shaped vertical steel 80 through the elastic member 53;

[0042] The limiting component is arranged on the frame 10 and is used to limit the position of the fixing plate 54 relative to the frame 10, so that in the limited state, the elastic member 53 is compressed, and the distance between the fixing plate 54 and the end of the frame 10 close to the H-shaped vertical steel 80 is smaller than the distance between the two wing plates of the H-shaped vertical steel 80; in the released state, the elastic member 53 is still in a relatively compressed state, so that the fixing plate 54 and the end of the frame 10 close to the H-shaped vertical steel 80 are respectively tightly attached to the inner sides of the two wing plates of the H-shaped vertical steel 80, so that the fixing plate 54, the elastic member 53 and the end of the frame 10 close to the H-shaped vertical steel 80 together form a fixing mechanism for fixing the auxiliary device to the H-shaped vertical steel 80 for a second time.

[0043] Specifically, the frame 10 includes a first frame segment 11 and a second frame segment 12 connected to each other. The width of the second frame segment 12 is smaller than that of the first frame segment 11, so that a force-bearing portion 13 ( Figure 1 ), the force-bearing portion 13 is provided for cooperating with the limiting assembly to facilitate the subsequent disassembly of the auxiliary device; the locking assembly 30 is provided at the bottom of the first frame segment 11, and the bottom of the first frame and the second frame are further provided with a guide column for guiding the connection of the two frames 10, for example, Figure 2 As shown, the guide column includes a hollow column 21 and a cross bar 22, which are respectively arranged on two symmetrical frames. One end of the hollow column 21 is open, and the diameter of the hollow column 21 is larger than the diameter of the cross bar 22. When the two frames 10 are connected, the cross bar 22 extends into the interior of the hollow column 21 through the open end of the hollow column 21, forming a transverse support rod at the bottom of the frame 10, which helps to improve the stability of the connection between the two frames 10. For example, to further improve the plug-in stability of the hollow column 21 and the cross bar 22, a structure similar to a mortise and tenon joint can be set on the hollow column 21 and the cross bar 22 respectively.

[0044] Exemplarily, the locking assembly 30 comprises a bidirectional screw 31 provided with two thread sections in opposite directions, a locking block 32 provided on the frame 10 and threadedly connected with the bidirectional screw 31, and a driving mechanism for driving the bidirectional screw 31 to rotate. The locking block 32 is provided with a threaded hole; and the driving mechanism is a handle 33 provided at one end of the bidirectional screw 31. When it is required to lock two frames 10, the handle 33 is rotated to drive the bidirectional screw 31 to rotate, so that the two frames 10 are relatively close and tightly fit. Exemplarily, as shown in Figure 3 FIG. 8, a limiting gear 34 can be provided on the bidirectional screw 31, so that the gear is located between the handle 33 and the side wall of the frame 10, and a stopper (not shown in the figure) is provided on the frame 10, so as to avoid unnecessary rotation of the bidirectional screw 31 and affect the locking effect. The specific structure of the stopper can refer to the prior art, so that the stopper can limit the bidirectional screw 31 after the locking is completed, for example, the limiting arrangement in CN117815818A. The driving mode of the above-mentioned driving mechanism is manual driving, and if necessary, other modes such as electric driving can be selected.

[0045] Specifically, the first frame section 11 is provided with a hollow box body 40 at one end away from the second frame section 12; a limiting assembly is provided on the box body 40 and comprises a horizontal piece 51, a control assembly for controlling the horizontal piece 51 to move up and down, and a clamping groove 541 provided on a fixing plate 54 and capable of being clamped with one end of the horizontal piece 51 close to the fixing plate 54. Exemplarily, the top and bottom of the box body 40 are both open, and the box body 40 is provided with a vertical through hole 41 away from the web; the control assembly comprises two vertical plates 521 connected by a first spring 522, the vertical plates 521 are connected with an adjusting plate 523 extending out of the box body 40 through the vertical through hole 41, and one end of the vertical plates 521 away from the first spring 522 extends upward or downward out of the box body 40 and is connected with the horizontal piece 51; the box body 40 is further provided with a limiting block 524 corresponding to the vertical plates 521, the limiting block 524 is provided with a guide hole, the vertical plates 521 pass through the guide hole and can move up and down relative to the guide hole Figure 4 Under the action of external force, the vertical movement of the adjusting plate 523 drives the vertical movement of the vertical plates 521, so that the horizontal piece 51 can move up and down. The guide hole can guide and limit the movement path of the vertical plates 521, thereby improving the stability of the control assembly.

[0046] The transverse piece 51 is provided with a clamping block 511 away from one end of the vertical plate 521, and the clamping block 511 is provided with a slope close to one end of the fixed plate 54. The slope of the slope extends away from the center of the fixed plate 54 in the direction close to the fixed plate 54, so that under the action of external force, the transverse piece 51 moves in the direction close to the fixed plate 54 and compresses the elastic piece 53 until the clamping block 511 falls into the clamping groove 541, the limiting assembly is in a limited state, the relative position between the fixed plate 54 and the frame 10 is fixed, and the distance between the fixed plate 54 and the frame 10 close to one end of the H-shaped vertical steel 80 is less than the distance between the two wings of the H-shaped vertical steel 80.

[0047] Regarding the two states of the transverse piece 51 and the clamping groove 541 being clamped and connected, that is, the limiting assembly is in a limiting state, or the transverse piece 51 does not limit the fixed plate 54, that is, the limiting assembly is in a state of being released, the state of the first spring 522 can be set as needed. For example, when the transverse piece 51 and the clamping groove 541 are clamped and connected, the first spring 522 can be set in a stretched state. At this time, under the action of the restoring force, the clamping block 511 on the transverse piece 51 will be tightly clamped in the clamping groove 541 in the vertical direction, ensuring the limiting effect of the limiting assembly on the fixed plate 54.

[0048] For example, the elastic piece 53 is a second spring.

[0049] Specifically, the second frame section 12 is also provided with a pushing structure for adjusting the horizontal position of the horizontal steel 90. The pushing structure includes a first clamping part 61 arranged at the bottom of each second frame section 12, a second clamping part 62 capable of being clamped and connected with the first clamping part 61 to form a roller structure, and a driving assembly for driving the roller structure to rotate. For example, as shown in the figure, Figure 5 and Figure 6As shown, the drive assembly includes an internally hollow transmission box 63 fixed at the bottom of the second frame segment 12, the transmission box 63 is provided with a through hole 631 on one side, and the transmission box 63 is connected with a crank 64 through a bearing, the part of the crank 64 located in the transmission box 63 is provided with a driving gear 65, and the other end of the crank 64 extends out of the transmission box 63 through the through hole 631; the first clamping part 61 is connected with the transmission box 63 through a bearing, and the end of the first clamping part 61 close to the transmission box 63 is connected with a driven gear 66 engaged with the driving gear 65, by controlling the rotation of the crank 64 to drive the driving gear 65 to rotate, the driving gear 65 drives the driven gear 66 to rotate, and then the drum structure is rotated, for example, the first clamping part 61 is provided with two, and the two sides of the corresponding driving gear 65 are respectively engaged with the driven gears 66; the second clamping part 62 is provided at the bottom of the other second frame segment 12 through a bearing structure, so that the second clamping part 62 can rotate relative to the second frame segment 12 under the action of the drive assembly. The diameter of the first clamping part 61 is greater than the diameter of the second clamping part 62, a plurality of transverse holes are provided in the first clamping part 61, and a plurality of transverse protrusions 621 are provided on the second clamping part 62 corresponding to the transverse holes, when the two frames 10 are connected, the transverse protrusions 621 extend into the transverse holes, so that the first clamping part 61 and the second clamping part 62 are connected to form a drum structure, and then the rotation of the drum structure drives the horizontal steel 90 to move horizontally, and the installation speed of the horizontal steel 90 is accelerated, in addition, the first clamping part 61 and the second clamping part 62 can also serve as a guide structure for guiding the connection of the two frames 10. The driving mode of the above-mentioned drive assembly is manual driving, if necessary, other modes such as electric driving can be selected.

[0050] The bottom of the second frame segment 12 is provided with an opening, and the rolling surface of the drum structure is placed on the bottom surface of the positioning cavity through the opening, so that when the horizontal steel 90 is located on the positioning frame, the bottom of the horizontal steel 90 is attached to the rolling surface of the drum structure.

[0051] For example, the wing plate of the H-shaped vertical rod is provided with a plurality of fixing holes for fixing the horizontal steel 90.

[0052] Specifically, the frame 10 is provided with a plurality of horizontal through holes 111 corresponding to the fixing holes at one end close to the H-shaped vertical steel 80, and the box body 40 is provided with a hole corresponding to the horizontal through hole 111. After the horizontal steel 90 moves to the preset position, the fixing bolt 92 is sequentially inserted through the fixing hole, the hole and the horizontal through hole 111 and is fixed by a nut, so that the horizontal steel 90 can be fixed on the H-shaped vertical steel 80; the size of the horizontal through hole 111 and the hole is greater than the size of the fixing bolt for the horizontal steel 90, so as to facilitate the disassembly of the subsequent auxiliary device. In addition, the horizontal through hole 111 and the hole can also be used to fix the frame 10 on the H-shaped vertical steel 80 by using the corresponding size of the locking bolt 70 during the installation of the auxiliary device on the H-shaped vertical steel 80 or after the fixation of the auxiliary device by the clamping mechanism and the fixing mechanism, so as to further provide support.

[0053] Specifically, the width of the positioning cavity close to the H-shaped vertical steel 80 is greater than the width of the horizontal steel 90 and the width of the positioning plate 91 located on the horizontal steel 90, and the width of the positioning cavity away from the H-shaped vertical steel 80 is slightly greater than the width of the horizontal steel 90. The positioning cavity close to the H-shaped vertical steel 80 can be used to preliminarily position the horizontal steel 90, and the positioning cavity away from the H-shaped vertical steel 80 can be used to accurately position the horizontal steel 90. The two-step positioning can quickly complete the alignment operation of the horizontal steel 90.

[0054] Specifically, a partial opening may be provided on the side wall of the frame 10 to reduce the weight of the auxiliary device without affecting the positioning effect of the cross steel 90 .

[0055] like Figure 7-Figure 9 As shown, in the embodiment of the present invention, when in use, the two frames 10 are moved to the preset position and the two frames 10 are brought close to each other, so that the bidirectional screw 31 threadedly connected to the bottom of one of the frames 10 passes through the locking block 32 at the bottom of the other frame 10, and at the same time, the hollow columns 21 at the bottom of the two first frame segments 11 and the two second frame segments 12 are sleeved with the cross bar 22, and the first clamping parts 61 and the second clamping parts 62 at the bottom of the two second frame segments 12 are clamped, and the bidirectional screw 31 is driven by the driving mechanism to rotate until the first frame 10 is close to the H-shaped vertical steel 80 and one end is tightly abutted against the side walls of the fixing plate 54 to form a clamping mechanism on both sides of the web. At this time, the hollow column 21 and the cross bar 22 as well as the first clamping part 61 and the second clamping part 62 are all connected; by controlling the two adjusting plates 523 to move away from each other, the limit assembly releases the restriction on the fixing plate 54, and under the restoring force of the elastic member 53, the fixing plate 54 and the first frame 10 are close to the H-shaped vertical steel One end of the steel 80 is respectively pressed against the inner sides of the two wing plates of the H-shaped vertical steel 80 to further provide support; the crane is used to make one end of the horizontal steel 90 with the positioning plate 91 fall into the positioning cavity close to the H-shaped vertical steel 80 for preliminary positioning, and then the other end of the horizontal steel 90 is slowly lowered downward so that part of the horizontal steel 90 falls into the positioning cavity away from the H-shaped vertical steel 80, thus completing the precise horizontal positioning of the horizontal steel 90, and controlling the crane so that part of the weight of the horizontal steel 90 is borne by the auxiliary device, that is, the bottom surface of the horizontal steel 90 is pressed against the The horizontal steel 90 is positioned on the bottom surface of the positioning cavity, thus completing the vertical positioning of the horizontal steel 90. Further, by driving the roller structure to rotate, the horizontal steel 90 is moved toward the H-shaped vertical steel 80 until the positioning plate 91 is attached to the outer side of the wing plate of the H-shaped vertical steel 80, thus completing the docking positioning of the horizontal steel 90. The fixing bolts 92 are sequentially passed through the fixing holes, the holes and the horizontal through holes 111 to the mounting holes on the horizontal steel 90, and the bolts are fixed with nuts to fix the horizontal steel 90 on the H-shaped vertical steel 80.

[0056] When the auxiliary device needs to be disassembled, a horizontal force is applied to the stress part 13 close to the H-shaped vertical steel 80, so that the clamping block 511 of the transverse piece 51 is close to the fixed plate 54 and clamped on the clamping groove 541. In this process, because the size of the horizontal through hole 111 and the hole is larger than the size of the fixed bolt 92, the frame 10 moves close to the H-shaped vertical steel 80 during the movement process, so that the frame 10 and the fixed plate 54 can pass through the fixed bolt 92, and then the bidirectional screw rod 31 is driven to rotate to move the two frames 10 away from each other to the position where the bidirectional screw rod 31 is separated from the locking block 32 at the bottom of the other frame 10, and the hollow column 21 is separated from the cross rod 22, the first clamping part 61 and the second clamping part 62 are separated, that is, the auxiliary device can be disassembled from the H-shaped vertical steel 80.

[0057] The auxiliary device of the present application is not only suitable for the horizontal steel 90 fixed by bolts, but also suitable for the horizontal steel 90 fixed by welding and other fixing methods.

[0058] In addition, regarding the installation of the auxiliary device, the horizontal through hole 111 and the hole can be used to first fix one frame 10 on the H-shaped vertical steel 80 by using the locking bolt 70, then fix the other frame 10 by using the locking assembly 30, and then further fix the auxiliary device by using the fixing mechanism. Before installing the horizontal steel 90, the locking bolt 70 is withdrawn from the horizontal through hole 111 and the hole, so as to facilitate the installation of the subsequent fixed bolt 92; or after the auxiliary device is fixed by using the clamping mechanism and the fixing mechanism, if there is a certain requirement for the bearing capacity of the auxiliary device during construction, the auxiliary device can be fixed on the H-shaped vertical steel 80 by using the locking bolt 70 to further provide support. When the horizontal steel 90 is installed subsequently, the locking bolt 70 can be removed while the fixed bolt 92 is installed. At this time, the fixed bolt 92 can provide support for the horizontal steel 90, and the auxiliary device can still be fixed on the H-shaped vertical steel 80 to provide support for the alignment positioning of the horizontal steel 90 due to the existence of the clamping mechanism and the fixing mechanism, thereby meeting the bearing requirement during construction and quickly realizing the alignment positioning of the horizontal steel 90.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
