Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to a device and a method for spatial positioning of square steel pipes. Background Art

[0002] With the continuous development of modern construction technology, building structures are becoming increasingly diverse, and steel structures have become one of the main building structure types in my country. Steel structures are characterized by high material strength, light weight, good toughness and plasticity, uniform material quality, and high structural reliability. Therefore, they are widely used in construction projects such as high-rise buildings, airports, stadiums, museums, and railway stations.

[0003] Steel roofs are a common component of steel structures. Due to their large size and the difficulty of high-altitude assembly, they are often assembled on the ground using individual steel members. Square steel tubes are a common component used in steel roofs. Due to the diverse nature of steel roofs, the spatial position of each square steel tube varies, making precise positioning difficult. Therefore, developing a more accurate, efficient, and practical square steel tube spatial positioning device and method is crucial for improving on-site assembly accuracy and construction efficiency of steel roofs.

[0004] There are currently two methods for spatial positioning of square steel tubes:

[0005] The first method is to set up a support frame on the ground in advance, and complete the spatial positioning of the square steel tube by tilting the support frame crossbar at a certain angle and using the height of the support frame itself. Since the support frame of this method needs to be installed and fixed in advance, the height positioning and tilt positioning of the support frame crossbar must be very accurate. If errors occur during the erection of the support frame, the square steel tube will be inaccurately positioned, affecting the installation quality. Secondly, since the spatial positions of square steel tubes are different, a large number of specific support frames need to be processed, resulting in a waste of resources. In addition, the support frame model must correspond one-to-one to the square steel tube, which greatly affects the on-site assembly efficiency.

[0006] The second method is to place the square steel pipe flat on the horizontal crossbar of the support frame, and then adjust the air posture of the square steel pipe with a hand winch to complete the spatial positioning of the square steel pipe. This method requires the use of auxiliary lifting equipment such as a crane to hang the hand winch, which increases the space occupied by the construction site. In addition, it is difficult to adjust the posture of the square steel pipe in one step using a hand winch. The arranged support frame is only suitable for height adjustment and cannot adjust the angle and horizontal direction. If the position between the square steel pipe and the connecting piece is offset after the square steel pipe is fixed, the subsequent position cannot be fine-tuned, resulting in an excessively large gap between the square steel pipe and the connecting piece, resulting in a large error.

[0007] Chinese patent application CN 107227738 A discloses a positioning structure and method for steel pipe columns in confined spaces. The structure comprises a steel casing, a steel pipe column, a lead screw, a nut, and a pile foundation. The steel casing houses the steel pipe column and the pile foundation. The steel pipe column is located above the casing, and a lead screw is connected to the bottom of the steel pipe column. One end of the lead screw passes through the nut to connect to the steel pipe column, while the other end of the lead screw rests on the wall of the steel casing. The nut is welded to the steel pipe column, and the pile foundation is located below the casing.

[0008] This patent uses a lead screw to adjust the horizontal position of a vertical steel pipe column, aligning the column center with the designed center position to complete the vertical adjustment. This method is used in steel pipe pile installation. However, this patent does not allow for vertical position adjustment or angular rotation. Summary of the Invention

[0009] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a device and a method for spatial positioning suitable for square steel pipes. The device is self-contained and has the function of adjusting the height, level, and angle of the square steel pipe. After the square steel pipe is fixed, the spatial position of the square steel pipe can also be fine-tuned, which greatly improves the assembly accuracy of the square steel pipe. Secondly, the device does not require holes or welding on the square steel pipe and does not destroy the original structure of the square steel pipe. In addition, the device also has the characteristics of repeated turnover, which effectively improves the assembly efficiency of the square steel pipe, reduces construction costs, and conforms to the concept of low carbon and environmental protection.

[0010] To achieve the above object, the present invention adopts the following technical solutions:

[0011] A device suitable for spatial positioning of square steel pipes, comprising an adjustable joint, wherein the adjustable joint is movably connected to a posture adjuster via a connecting component, the posture adjuster is movably connected to a supporting main rod via a connecting buckle, and the supporting main rod is mounted on a movable supporting base;

[0012] The adjustable joint includes four L-shaped hoop plates symmetrically connected to the outside of the square steel tube. The four L-shaped hoop plates are connected into a group, and the two connected and side-by-side groups are connected by a connecting piece. The two ends of each L-shaped hoop plate are provided with a first connecting end plate facing outward and perpendicular to the end. A through hole is provided on the first connecting end plate, and the two adjacent L-shaped hoop plates are passed through the through hole by a first connecting bolt and fastened by a nut; a layer of anti-wear pad is provided on the inner wall of the L-shaped hoop plate in contact with the square steel tube; a threaded through hole is provided at the bending part of the L-shaped hoop plate, and the two connected and side-by-side groups are connected by a first connecting screw passing through the corresponding threaded through hole and fastened by a connecting nut.

[0013] The posture adjuster includes a long arm and a short arm connected in a T-shape, wherein the two ends of the long arm are movably connected to the screw rod and the supporting main rod at the lower half of the adjustable joint, and the other end of the short arm is movably connected to the supporting main rod.

[0014] The long arm includes a supporting long rod and a supporting short rod. One end of the supporting long rod is connected to one end of the positive and negative wire sleeve through a second connecting screw, and the other end of the positive and negative wire sleeve is connected to one end of the supporting short rod through another second connecting screw. The other ends of the supporting long rod and the supporting short rod are both provided with a connecting swivel, which can be rotatably connected to the middle of the connecting end of the connecting buckle through a connecting bolt.

[0015] A first rotating rod is fixed on the positive and negative wire sleeve.

[0016] The short arm includes two supporting short rods, and the opposite ends of the two supporting short rods are respectively connected to another forward and reverse wire sleeve through two other second connecting screws. The other ends of the two supporting short rods are respectively provided with another connecting rotary head, and one of the connecting rotary heads is fixed to the supporting long rod of the long arm through a connecting buckle.

[0017] Another first rotating rod is fixed on the other forward and reverse wire sleeve.

[0018] The supporting main rod includes a supporting cross bar assembly and a supporting vertical bar assembly. Both ends of the supporting cross bar assembly are fixed to the supporting vertical bar assembly through connecting buckles respectively. Multiple supporting cross bar assemblies and supporting vertical bar assemblies together form a frame structure.

[0019] The support crossbar assembly includes two support crossbars, one end of each support crossbar is provided with an internal thread, and the other end is provided with a second connecting end plate, the threaded ends of the two support crossbars are connected by a fourth connecting screw, and the fourth connecting screw is provided with a third rotating rod.

[0020] The support vertical rod assembly includes two support vertical rods with internal threads at both ends. The two support vertical rods are connected by a third connecting screw rod, and a second rotating rod is provided on the third connecting screw rod.

[0021] The connecting buckle includes a first connecting buckle and a second connecting buckle, and the first connecting buckle and the second connecting buckle both include a cylindrical buckle. A layer of friction steel plate is provided on the inner wall of the cylindrical buckle, and transverse ribs are provided on the inner wall of the friction steel plate. Two groups of connecting ends are symmetrically provided on the outer surface of the cylindrical buckle, and each group of connecting ends are two parallel ends. Bolt holes are opened on the ends, and bolts are passed through the bolt holes and fixed by nuts.

[0022] The movable support base comprises a support base and a universal wheel at the bottom. A support screw connected to the support main rod is vertically arranged at the center of the upper part of the support base.

[0023] A spatial positioning method for a device suitable for spatial positioning of square steel tubes comprises the following steps:

[0024] 1) Arrange the mobile support base according to the measured position of the square steel pipe. After the mobile support base reaches the designated position, lock the universal wheel.

[0025] 2) Erect the main support pole, adjust the vertical support pole by rotating the second rotating rod on the third connecting screw, and adjust the length of the horizontal support pole by rotating the third rotating rod on the fourth connecting screw. Then, connect the vertical support pole and the horizontal support pole with the connecting buckle to complete the erection of the main support pole;

[0026] 3) First, assemble the attitude adjuster, and then calculate the installation position of the connecting buckle on the supporting vertical rod according to the height of the square steel tube, to ensure that there is enough margin for the second connecting screw in the positive and negative thread sleeves when adjusting the angle of the square steel tube later;

[0027] Next, install the connecting buckle, connect the connecting head of the attitude adjuster to the connecting end of the connecting buckle on the supporting vertical rod, so that the attitude adjuster is fixed on the supporting vertical rod, and then connect the lower half of the adjustable joint to the other connecting head of the attitude adjuster through the first connecting screw, so that the lower half of the adjustable joint is in a horizontal state, and the anti-wear pads on the left and right adjustable joints are at the same height, and then tighten the connecting nut to fix it;

[0028] Then open the locking piece of the universal wheel, adjust the length of the supporting crossbar through the third rotating rod of the fourth connecting screw, so that the L-shaped hoop plates on the lower half of the left and right adjustable joints clamp the square steel pipe to be installed, then lock the universal wheel, connect and fix the lower half of the left and right adjustable joints through the first connecting end plate with the first connecting bolt, and finally connect the upper half of the adjustable joints with the first connecting bolt and the first connecting screw, and tighten the connecting nut to fix the square steel pipe;

[0029] 4) Turn the second rotating rod on the third connecting screw connected to the supporting vertical rod to adjust the square steel pipe to the specified height, completing the height adjustment of the square steel pipe;

[0030] 5) According to the tilt position of the square steel tube, the attitude adjuster on the non-tilted side is fixed, and the bottom height of the square steel tube on this side is equal to the bottom height of the square steel tube in the tilted state; then half-tighten the connecting nut on the first connecting screw connecting the lower half of the adjustable joint to the attitude adjuster on the tilted side, so that the long arm of the attitude adjuster on the tilted side can rotate;

[0031] Then half-tighten the connecting nut on the first connecting screw connecting the lower half of the adjustable joint to the attitude adjuster on the non-tilted side. With the first connecting screw at the non-tilted end as the rotating shaft, rotate the first rotating rod on the positive and negative thread sleeve of the attitude adjuster on the tilted side to extend the long arm and shorten the short arm to drive the square steel pipe to rotate, so that the height of the raised side of the square steel pipe is equal to the height of the side of the square steel pipe in the tilted state. Then tighten all the connecting nuts to fix it, and complete the angle adjustment of the square steel pipe.

[0032] 6) Open the locking piece of the universal wheel, adjust the horizontal position of the square steel tube in the front, back, left and right directions, align the end point of the square steel tube with the measured point, and then lock the universal wheel to complete the horizontal position adjustment of the square steel tube.

[0033] The beneficial effects of the present invention are:

[0034] 1. High precision: This device can complete the adjustment of various spatial postures of square steel pipes. After installation, it can also fine-tune the various postures of square steel pipes in the air again to achieve high-precision node positioning and assembly, ensuring the overall accuracy of square steel pipe assembly.

[0035] 2. Strong flexibility: This device and its use method can fix square steel pipes of different sizes by using adjustable joints. Various spatial postures of the square steel pipes can be adjusted through the posture adjuster, the length-adjustable support main rod and the movable support base, which has strong flexibility.

[0036] 3. Does not damage the original structure of the steel column. The square steel pipe is fixed by an adjustable joint, and the inner wall of the adjustable joint has an anti-wear pad, which does not damage the original structure of the square steel pipe and ensures the mechanical properties of the square steel pipe.

[0037] 4. Reuse and cost reduction: This device adopts a temporary fixation method and can be recycled after use. It does not require the production of a large-scale support frame, thus reducing costs.

[0038] In short, this device and its use method can improve assembly efficiency, ensure assembly accuracy, and adapt to the assembly needs of square steel tubes of different shapes and sizes. It has strong practicality and promotion value.

[0039] The overall structural arrangement can prevent the square steel pipe from shaking or tilting during the subsequent welding process, thereby ensuring the safety and reliability of the assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] like Figures 1-13 As shown, the device for spatially positioning square steel tubes includes an adjustable joint 1, which is in close contact with the square steel tube 6. The lower half of the adjustable joint 1 is connected to the posture adjuster 2 via a first connecting screw 105. The posture adjuster 2 is movably connected to the support vertical rod 3 via a second connecting buckle 302. The support cross bar 4 is movably connected to the support vertical rod 3 via the second connecting buckle 302. The support vertical rod 3 is mounted on a movable support base 5.

[0062] The adjustable joint 1 includes four L-shaped hoop plates 101 symmetrically connected to the exterior of the square steel tube 6. The four L-shaped hoop plates 101 are connected as a group, and two adjacent, side-by-side groups are connected via connectors. Adjusting the spacing between the L-shaped hoop plates 101 allows for adaptability to components of varying sizes. Each L-shaped hoop plate 101 is provided at both ends with a first connecting end plate 102 perpendicular to the end, facing outward. The first connecting end plate 102 has a through hole. Two adjacent L-shaped hoop plates 101 are connected by first connecting bolts 107 passing through the through holes and fastened with nuts. The L-shaped hoop plates are connected by first connecting bolts 107 passing through the first connecting end plates 102, thereby securing the square steel tube 6.

[0063] A layer of anti-wear pad 103 is provided on the inner wall of the L-shaped hoop plate 101 in contact with the square steel pipe 6. The anti-wear pad 103 is in close contact with the surface of the square steel pipe 6 to avoid wear of the surface coating of the square steel pipe 6.

[0064] A threaded through hole 104 is provided at the bend of the L-shaped hoop plate 101 . The two connected and parallel groups are connected by a first connecting screw 105 passing through the corresponding threaded through hole 104 and fastened by a connecting nut 106 .

[0065] The first connecting screw 105 on the upper half of the adjustable joint 1 passes through the threaded through hole 104 to connect the front and rear L-shaped hoop plates 101, and the connecting nut 106 is tightened to fix the square steel pipe;

[0066] The first connecting screw 105 of the lower half of the adjustable joint 1 passes through the threaded through hole 104 to connect to the posture adjuster 2. By adjusting the tightness of the lower half connecting nut 106, the connecting nut 106 is in a semi-tightened state, which plays a role in rotation. After the rotation is completed, the connecting nut 106 is tightened to play a fixing role.

[0067] The upper portion of the attitude adjuster 2 is connected to the first connecting screw 105 of the adjustable joint 1 via a connecting swivel 201 and to the second connecting buckle 302 on the support vertical rod 3 via a connecting swivel 201. The lower portion is connected to another second connecting buckle 302 fixed to the support vertical rod 3 via another connecting swivel 201. This device mainly serves to adjust the posture of the square steel tube 6 and to support and fix it.

[0068] The posture adjuster 2 includes a long arm 208 and a short arm 209 connected in a T-shape. The two ends of the long arm 208 are movably connected to the first connecting screw 105 and the support vertical rod 3 in the lower half of the adjustable joint 1, and the other end of the short arm 209 is movably connected to the support vertical rod 3.

[0069] The long arm 208 includes a long support rod 207 and a short support rod 202. The short support rod 202 and the long support rod 207 serve as supports. One end of the long support rod 207 is connected to one end of the forward and reverse thread sleeve 204 via a second connecting screw 203. The other end of the forward and reverse thread sleeve 204 is connected to one end of the short support rod 202 via another second connecting screw 203. The other ends of the long support rod 207 and the short support rod 202 are each provided with a connecting swivel 201. The connecting swivel 201 connects the posture adjuster 2 to the adjustable joint 1 and the support vertical rod 3, and provides a swivel for the rotation of the square steel tube 6. A first rotating rod 205 is fixed to the forward and reverse thread sleeve 204.

[0070] One end of the second connecting screw 203 is welded to the supporting short rod 202 and the supporting long rod 207, and the other end is connected to the positive and negative wire sleeve 204, playing the role of connection and support.

[0071] The short arm 209 comprises two supporting short rods 202, each connected at one end to a forward and reverse thread sleeve 204 via a second connecting screw 203. The other ends of the two supporting short rods are each provided with a connecting turret 201, one of which is secured to a supporting long rod 207 of the long arm 208 via a first connecting buckle 206. A second first rotating rod 205 is secured to the forward and reverse thread sleeve 204. Rotating the forward and reverse thread sleeve 204 via the first rotating rod 205 allows the long arm 208 and short arm 209 of the attitude adjuster 2 to extend and retract, thereby adjusting the angle of the square steel tube 6.

[0072] The first connecting buckle 206 comprises a cylindrical buckle 206-1, the inner wall of which is provided with a friction steel plate 206-2, which is also provided with transverse ribs. Two sets of connecting ends 206-3 are symmetrically arranged on the outer surface of the cylindrical buckle 206-1. Each set of connecting ends 206-3 comprises two parallel ends, each with a bolt hole through which a second connecting bolt 206-4 passes and is secured with a nut. The first connecting buckle 206 connects the long arm 208 and the short arm 209 to form the posture adjuster 2.

[0073] By rotating the first rotating rod 205 on the forward and reverse wire sleeve 204, the long arm 208 and the short arm 209 are extended and retracted, pushing the square steel tube 6 to rotate and adjust the angle of the square steel tube 6. After the angle adjustment is completed, the posture adjuster 2 can provide support for the square steel tube 6, thereby ensuring the safety and reliability of assembly.

[0074] The vertical support rod 3 comprises a vertical support assembly and a second connecting buckle 302. The vertical support assembly comprises a vertical support circular tube 301 with internal threads at both ends. The vertical support circular tube 301 is connected via a third connecting screw 303, which is equipped with a second rotating rod 304. The third connecting screw 303 is primarily used to connect the vertical support circular tube 301 and can be rotated to adjust the rod length and the vertical height of the square steel tube 6. The second connecting buckle 302 comprises a cylindrical buckle 302-1, the inner wall of which is provided with a friction steel plate 302-2, which is also provided with transverse ribs. The outer surface of the cylindrical buckle 302-1 is symmetrically provided with two sets of connecting end caps 302-3. Each set of connecting end caps 302-3 is parallel and has bolt holes. The bolt holes are passed through by second connecting bolts 302-4 and secured by nuts. The second connecting buckle 302 primarily connects, secures, and positions the height of the square steel tube. The connecting head 201 of the attitude adjuster 2 is rotatably connected to the connecting end 302-3 and the second connecting bolt 302-4, allowing the end of the long arm 208 connected to the second connecting bolt 302-4 to rotate and also securing the attitude adjuster 2. A cylindrical buckle 302-1 and a friction plate 302-2 are connected to the vertical support tube 301. The cylindrical buckle 302-1 can hold the vertical support tube 301. The friction plate 302-2 contains horizontal ribs that increase friction with the rod surface, allowing the second connecting buckle 302 to be firmly fixed to the vertical support tube 301. The second connecting buckle 302 also connects the vertical support rod 3 to the horizontal support rod 4. Furthermore, the position of the second connecting buckle 302 on the vertical support tube 301 also affects the height of the square steel tube.

[0075] The supporting cross bar 4 mainly plays a supporting role. The component includes two transverse supporting circular tubes 402. One end of each transverse supporting circular tube 402 has an internal thread, and the other end is provided with a second connecting end plate 401. The threaded ends of the two transverse supporting circular tubes 402 are connected by a fourth connecting screw 403, and the fourth connecting screw 403 is provided with a third rotating rod 404.

[0076] The movable support base 5 includes a support base 502 and a universal wheel 503 at the bottom. A support screw 501 connected to the support vertical rod 3 is vertically provided at the center of the upper part of the support base 502.

Use the first connecting bolt 107 to connect and secure the left and right L-shaped hoop plates 101 in the lower half. Then, use the first connecting screw 105 through the threaded hole 104 to connect the front and back L-shaped hoop plates 101 in the upper half of the adjustable joint 1. Then, use the first connecting bolt 107 through the first connecting end plate 102 to connect the left and right L-shaped hoop plates 101 in the upper half. Finally, connect the upper and lower L-shaped hoop plates 101 with the first connecting bolt 107 and tighten the nut to secure the square steel pipe 6, completing the assembly of the adjustable joint 1. The anti-wear pad 103 is in close contact with the surface of the square steel pipe 6, preventing wear on the surface coating of the square steel pipe 6.

[0082] Square steel pipe spatial positioning method suitable for device for square steel pipe spatial positioning

[0083] <1> The movable support base 5 is arranged according to the measured position of the square steel pipe. After the movable support base 5 reaches the designated position, the universal wheel 503 is locked.

[0084] <2> Set up the main support pole. Adjust the length of the vertical support pole 3 by rotating the second rotating rod 304 on the third connecting screw 303, then adjust the length of the horizontal support pole 4 by rotating the third rotating rod 404 on the fourth connecting screw 403, and finally connect the vertical support pole 3 and the horizontal support pole 4 through the second connecting buckle 302 to complete the erection of the main support pole. (Connection nodes are as follows Figure 9shown)
