Description

Technical Field

[0001] The invention belongs to the technical field of steel beam construction, and in particular relates to a construction method for avoiding collision between a steel column and a steel beam. Background Art

[0002] With the rapid development of the construction industry, building structures are becoming increasingly complex, and cross-operation of multiple types of work is becoming more frequent. In the process of setting up structural measures, conflicts with existing structural components often occur. For example, in the construction of the basement, lattice supports are temporarily set up at the installation location of the steel beam, but when the steel beam needs to be installed, these supports have not been removed, resulting in the failure of the smooth installation of the steel beam. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art and to provide a construction method for avoiding the collision between steel columns and steel beams. A part of the steel column that hinders the passage of the steel beam is cut to leave space in the collision area between the steel column and the steel beam for the steel beam to pass through. Steel components are used to transfer the load to the two sections of steel columns distributed above and below to meet the normal installation of the steel beam.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A construction method for avoiding collision between steel columns and steel beams, characterized in that it comprises the following steps:

[0006] S1. Weld two upper and lower hoop components on the steel column. A single hoop component uses square steel tube 1 and square steel tube 2:

[0007] (1) Weld the steel plate onto the steel column, and then weld the square steel tube onto the steel plate.

[0008] (2) According to the position of square steel tube one, square steel tube two is welded to the steel plate, and then square steel tube two and square steel tube one are welded and fixed.

[0009] S2. Welding support components, including legs and support tubes:

[0010] (1) Weld the legs on the outside of the second square steel tube.

[0011] (2) Weld the support tube between the two legs on the same side.

[0012] S3. Welded reinforcement components, the reinforcement components include inclined steel pipe 1 and inclined steel pipe 2:

[0013] (1) Weld the inclined steel pipe 1 to the support leg and the square steel pipe 2.

[0014] (2) Weld the inclined steel pipe to the steel plates of the support legs and steel columns.

[0015] S4. A collision area is formed between the upper and lower hoop components, the steel column in the collision area is cut off, and the cut part is taken out. At this time, the steel column is divided into two steel column sections distributed up and down, and the end face of the steel column section does not extend into the collision area.

[0016] S5. Install the steel beam and pass it through the collision area.

[0017] Further, a steel pipe positioning device is used to perform positioning welding on the other steel pipe. The steel pipe positioning device includes a mounting seat and a clamping structure. Two clamping structures are installed on the mounting seat. The specific steps are as follows:

[0018] 1) Install the mounting base of the steel pipe positioning device on the workbench on the ground, and then use the clamping structure to clamp the square steel pipe.

[0019] 2) Adjust the position of the clamping structure on the mounting seat on the workbench so that the distance between the two square steel pipes on the same mounting seat is the designed distance.

[0020] 3) The clamping structure is hoisted, the mounting base is separated from the workbench, and then the mounting base is fixed to the steel column. At this time, the square steel pipe is tightly attached to the steel plate, and then the square steel pipe is welded to the steel plate.

[0021] 4) After the inclined steel pipe 2 is welded on the steel plates of the support legs and steel columns, remove the steel pipe positioning device.

[0022] Furthermore, the mounting base is provided with a through hole, and the specific steps of fixing the mounting base to the steel column are:

[0023] 1) Drill holes on the steel column to form mounting holes.

[0024] 2) Insert the fixing rod into the installation hole. When the fixing rod extends to the same length as the steel column, weld the fixing rod and the steel column to fix them. Then, thread the locking nut 1 onto the fixing rod and screw the locking nut 1 onto the steel column.

[0025] 3) Install the mounting base on the fixing rod. At this time, the fixing rod passes through the through hole of the mounting base. When the square steel pipe 1 is tightly attached to the steel plate, thread the locking nut 2 on the fixing rod, and lock the locking nut 2 on the mounting surface 1 of the mounting base. Then, turn the locking nut 1 to lock the locking nut 1 on the mounting surface 2 of the mounting base, so that the locking nut 1 and the locking nut 2 clamp the mounting base.

[0026] Furthermore, before drilling holes in the steel column, a reinforcing plate is welded on the steel column.

[0027] Further, the clamping structure is installed in front of the mounting seat, and the mounting seat is placed on the workbench. At this time, the limiting column vertically arranged on the workbench passes through the through hole of the mounting seat, so that the mounting seat is limited on the workbench.

[0028] Furthermore, the clamping structure includes a sliding seat, a clamping plate 1, a clamping plate 2 and a limit rod. The clamping plate 1 is welded on the sliding seat. The clamping plate 1 and the clamping plate 2 are both provided with notches. The specific steps of clamping the square steel pipe 1 are as follows:

[0029] 1) Install the sliding seat onto the mounting base.

[0030] 2) Weld I-beams on the workbench so that the top surfaces of all I-beams are at the same height.

[0031] 3) Place square steel tube 1 on the I-beam, then attach clamping plate 1 on the sliding seat to the side of square steel tube 1, then attach clamping plate 2 to the other side of square steel tube 1, then pass the limit rod through the slots of clamping plate 1 and clamping plate 2, then thread the fixing nuts at both ends of the limit rod, then move the limit rod upward in the slot so that the limit rod supports square steel tube 1, then tighten the fixing nuts, and lock one of the fixing nuts on clamping plate 1, and lock the other fixing nut on clamping plate 2, so that clamping plate 1 and clamping plate 2 clamp square steel tube 1, the height of the top surface of square steel tube 1 is greater than the height of the top surface of clamping plate 1, and at the same time, the height of the top surface of square steel tube 1 is greater than the height of the top surface of clamping plate 2.

[0032] Furthermore, the sliding seat is provided with a connecting hole and a threaded hole, the threaded hole and the connecting hole are connected, and the mounting seat is welded with a connecting plate. The specific steps of installing the sliding seat to the mounting seat are:

[0033] 1) Pass the connecting plate of the mounting seat through the connecting hole of the sliding seat.

[0034] 2) Screw the fixing bolts into the threaded holes. The fixing bolts are used to lock the sides of the connecting plate.

[0035] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0036] The present invention welds two hoop components distributed up and down on the steel column, the hoop components extend outwardly from the steel column, and the cross-sectional area of ​​the hoop components is larger than the cross-sectional area of ​​the steel column. The present invention welds a leg on the outside of the second square steel tube, and welds a support tube between the two legs on the same side, which can increase the distance between the support tubes, and is used to increase the space of the collision area to meet the requirements of the steel beam with a set size to pass through later.

[0037] Considering the deformation of the legs and the support tube, the present invention aims at solving this technical problem by welding the inclined steel tube 1 on the legs and the square steel tube 2 to increase the force bearing capacity of the legs, and then welding the inclined steel tube 2 on the steel plates of the legs and the steel columns. The force on the inclined steel tube 2 can be transmitted to the steel column through the inclined steel tube 2, so that the added steel component has good stability and small deformation of the steel component. When the steel column in the collision area is cut off and the cut part is taken out, the steel beam passes through the space in the collision area.

[0038] The present invention adopts steel components to transfer loads to two steel column sections distributed up and down, thereby meeting the requirements for normal installation of steel beams. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0062] like Figures 1 to 17 As shown in FIG. 1 , a construction method for avoiding collision between steel columns and steel beams according to the present invention is shown, in which the steel column 17 is made of angle steel.

[0063] The method comprises the following steps:

[0064] S1. Weld two hoop components distributed up and down on the steel column 17. A single hoop component uses a square steel tube 15 and a square steel tube 24:

[0065] (1) A steel plate 18 is welded to the steel column 17. The thickness of the steel plate 18 is 14 mm. Then, a square steel tube 15 is welded to the steel plate 18.

[0066] (2) According to the position of the square steel pipe 15, the square steel pipe 24 is welded to the steel plate 18, and then the square steel pipe 24 and the square steel pipe 15 are welded and fixed.

[0067] S2. Welding a support member, the support member includes a support leg 25 and a support tube 26:

[0068] (1) Weld the support leg 25 on the outside of the square steel pipe 24.

[0069] (2) A vertical support tube 26 is welded between two legs 25 on the same side.

[0070] S3, welding reinforcement components, the reinforcement components include inclined steel pipe 1 27 and inclined steel pipe 2 28:

[0071] (1) Weld the inclined steel pipe 1 27 to the support leg 25 and the square steel pipe 2 24.

[0072] (2) Weld the inclined steel pipe 28 to the support leg 25 and the steel plate 18 of the steel column 17.

[0073] S4. A collision area 29 is formed between the upper and lower hoop components, a portion of the steel column 17 in the collision area 29 is cut off, and then the cut portion is taken out. At this time, the steel column 17 is divided into two steel column segments a distributed vertically, and the end face b of the steel column segment a does not extend into the collision area 29.

[0074] S5. Install the steel beam and pass it through the collision area 29.

[0075] When the welding position of the square steel tube 15 of the present invention deviates, the welding position of the entire hoop member will deviate, and then the welding position of the supporting member will deviate. At this time, the position of the collision area 29 does not meet the design requirements, causing the steel beam to be unable to pass through the collision area 29. Based on the above embodiment, the present invention designs another embodiment:

[0076] The present invention positions and welds the square steel tube 15 to the steel plate 18, thereby ensuring that the welding position of the square steel tube 15 is accurate.

[0077] Specifically, a steel pipe positioning device is used to perform positioning welding on the other steel pipe 15, such as Figure 7 As shown, the steel pipe positioning device includes a mounting seat 3 and a clamping structure. Two clamping structures are installed on the mounting seat 3. The mounting seat 3 is provided with a through hole 16 and a connecting plate 4. The specific steps are:

[0078] 1) Place a workbench 1 on the ground, and the workbench 1 is provided with a vertical limiting column 2. Then place the mounting seat 3 on the workbench 1, and the limiting column 2 on the workbench 1 passes through the through hole 16 of the mounting seat 3, so that the mounting seat 3 is limited on the workbench 1, so that the mounting seat 3 will not be displaced during the process of clamping the square steel pipe 15 with the clamping structure in the later stage, which is convenient for controlling the installation position of the square steel pipe 15.

[0079] 2) Use clamping structure to clamp square steel pipe 15:

[0080] The clamping structure includes a sliding seat 5, a clamping plate 1 6, a clamping plate 2 13 and a limit rod 11. The clamping plate 1 6 is welded to the sliding seat 5. The clamping plate 1 6 and the clamping plate 2 13 are both provided with a notch 9. The sliding seat 5 is provided with a connecting hole 7 and a threaded hole 8. The threaded hole 8 is connected to the connecting hole 7. The specific steps are:

[0081] In the first step, the connecting plate 4 of the mounting seat 3 is passed through the connecting hole 7 of the sliding seat 5 , and then the fixing bolts 10 are screwed into the threaded holes 8 , and the sliding seat 5 is installed on the mounting seat 3 .

[0082] In the second step, the I-beams 14 are welded on the workbench 1 , and the top surfaces of all the I-beams 14 are at the same height.

[0083] The third step is to place the square steel tube 15 on the I-beam 14 and control the distance between the two square steel tubes 15 so that the spacing between the two square steel tubes 15 meets the construction requirements. At this time, the heights of the two square steel tubes 15 are the same. When the square steel tubes 15 are subsequently positioned and welded, the two square steel tubes 15 can be attached to the steel plate 18, avoiding the problem that one square steel tube 15 cannot be attached. Then attach the clamping plate 6 on the sliding seat 5 to the side of the square steel tube 15, and then tighten the fixing bolts 10 against the side of the connecting plate 4. Then, the clamping plate 13 is attached to the other side of the square steel tube 15, and the limiting rod 11 is passed through the notch 9 of the clamping plate 6 and the notch 9 of the clamping plate 13, and then the fixing nuts 12 are threadedly connected at both ends of the limiting rod 11, and then the limiting rod 11 is moved upward in the notch 9 so that the limiting rod 11 supports the square steel tube 15, and then the fixing nuts 12 are tightened, and one of the fixing nuts 12 is locked on the clamping plate 6, and the other fixing nut 12 is locked on the clamping plate 13, so that the clamping plate 16 and the clamping plate 2 13 clamp the square steel tube 15, and the height of the top surface of the square steel tube 15 is greater than the height of the top surface of the clamping plate 6, and at the same time, the height of the top surface of the square steel tube 15 is greater than the height of the top surface of the clamping plate 2 13, so that the entire top surface of the square steel tube 15 is exposed, which is convenient for the top surface of the square steel tube 15 to fit with the steel plate 18.

[0084] The above steps 1) and 2) are both completed on the ground, reducing high-altitude operations and improving safety.

[0085] 3) A reinforcing plate 20 is welded on the steel column 17 to increase the strength of the steel column 17 , and then a hole is punched on the steel column 17 to prevent the steel column 17 from being deformed during punching, and a mounting hole 19 is formed on the steel column 17 .

[0086] 4) Insert the fixing rod 21 into the mounting hole 19. When the fixing rod 21 extends to the same length as the steel column 17, weld the fixing rod 21 and the steel column 17 to fix them. The fixing rod 21 can simultaneously install two mounting seats 3. Then, thread the locking nut 22 on the fixing rod 21 and screw the locking nut 22 onto the steel column 17 to prevent the locking nut 22 from affecting the installation of the square steel pipe 15.

[0087] 5) The clamping structure is hoisted, and the mounting seat 3 of the steel pipe positioning device is now separated from the workbench 1. The mounting seat 3 of the steel pipe positioning device is then mounted on the fixing rod 21, and the fixing rod 21 passes through the through hole 16 of the mounting seat 3. When the square steel pipe 15 is tightly attached to the steel plate 18, the locking nut 23 is threadedly connected to the fixing rod 21, and the locking nut 23 is locked on the mounting surface 1b of the mounting seat 3, and then the locking nut 122 is screwed and locked on the mounting surface 2a of the mounting seat 3, so that the locking nut 122 and the locking nut 23 clamp the mounting seat 3, and then the square steel pipe 15 is welded to the steel plate 18.

[0088] During this process, the square steel tube 15 is first pressed against the steel plate 18, and then the mounting seat 3 is clamped so that the square steel tube 15 is in contact with the steel plate 18, and there is a certain distance between the mounting seat 3 and the steel column 17, ensuring that the square steel tube 15 is completely pressed against the steel plate 18.

[0089] When the square steel tube 15 is welded to the steel plate 18, the installation position of the square steel tube 15 can be ensured to be accurate, thereby avoiding deviation in the welding position of the supporting member and ensuring that the position of the collision area 29 meets the design requirements. Moreover, when welding the hoop member, the supporting member and the reinforcing member, the force can be transmitted to the steel column 17 through the steel tube positioning device, thereby improving the stability of each member during welding and improving the safety of welding.

[0090] 6) After the inclined steel pipe 28 is welded to the steel plate 18 of the support leg 25 and the steel column 17, the steel pipe positioning device is removed and the entire steel pipe positioning device is recycled.

[0091] like Fig.18 and Fig.19 As shown, after step S5 of the present invention is completed, the hoop member, the supporting member and the reinforcing member form a conversion device. Calculation shows that the XY deformation of the conversion device is 1.36 mm, the vertical deformation is 2.43 mm, and the deformation of the steel member is relatively small.

[0092] like Fig. 20 As shown, the maximum stress value of the support tube 26 is 125.13 MPa, and the maximum stress ratio is 0.654<0.85. Fig.21 As shown in the figure, the maximum stress value of the angle steel on one side is 157.08MPa, which is relatively small and meets the construction requirements.

[0093] According to the strength calculation formula of right-angle fillet weld in Article 11.2.2 of "Steel Structure Design Standard" GB50017-2017:

[0094] The steel components of the conversion device are all square steels made of Q235B, and the square steels are connected by fillet welds.

[0095] Since there are four welds bearing shear force, each weld bearing shear force is 150kN, the weld length is 500mm, and the weld height is 10mm, it can be obtained that he=0.7*10=7mm, lw=500-2*10=480mm, and it can be obtained that:

[0096]

[0097] The fillet weld meets the shear strength requirements.

[0098] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
