Description

Technical Field

[0001] The present invention relates to the technical field of steel section hoisting construction, specifically to a deepened structure and construction method for steel section hoisting construction. Background Technique

[0002] With the development of society, the number of steel structure buildings is increasing day by day. Mainly compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections to replace reinforced concrete, with higher strength and better seismic resistance. Therefore, hoisting steel sections has become an important part of steel structure buildings.

[0003] For example, a fixture for hoisting H-shaped steel beams and its hoisting method are disclosed in a Chinese patent (publication number: CN 109573813 A). The steps are as follows: Step 1: Rectify the H-shaped steel beam into a "worker" shape to facilitate the symmetric buckling of the hoisting fixture; Step 2: Symmetrically buckle the hoisting fixture with the distal ends of the steel beam flange plates on both sides of the H-shaped steel beam to avoid imbalance due to overweight; Step 3: Connect the two strands of the steel wire rope to the hoisting holes separately, and it is convenient to lift after being fastened; Step 4: Lift the steel wire rope by the hook of the crane for hoisting. The whole process is convenient to operate, flexible, and efficient.

[0004] However, the above technical solutions still have the following defects. The above technical solutions mainly aim at hoisting steel sections with relatively small volumes. For hoisting steel sections with relatively large volumes, it is difficult to achieve. At the same time, during the hoisting process, the side of the steel section is hoisted by the hoisting tool, and the end face of the steel section cannot be hoisted. This leads to the need to re-erect the steel section vertically during the installation and alignment of the steel section, with low efficiency. In addition, for the vertical hoisting of steel sections, a hoisting tool is usually used in cooperation with a lifting lug. Traditional hoisting tools usually weld lifting lugs on the surface of the steel section, and then hoist the steel section with the hoisting tool in cooperation with the lifting lug, with poor stability, and large-scale welding is likely to affect the molecular structure of the steel section. Based on this, a deepened structure and construction method for steel section hoisting construction are proposed to solve the above problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a deepened structure and construction method for steel section hoisting construction, which has the advantages of high construction efficiency and solves the problem of low construction efficiency of steel section hoisting construction.

[0006] To achieve the above object, the present invention provides the following technical solution: A deepened structure for steel section hoisting construction, including an installation surface and a hoisted steel section. The hoisted steel section is perpendicular to the upper part of the installation surface. A calibration and installation mechanism is provided between the installation surface and the hoisted steel section, and a fixture is provided above the hoisted steel section.

[0007] The fixture is used for clamping and lifting the hoisted section steel, and the fixture includes a box body located at the top of the hoisted section steel. Cavities are provided at both the left and right ends of the box body. Sliders are slidably connected inside the cavities. Connecting rods are fixed to the opposite ends of the two sliders. Return springs are fixed between the opposite ends of the two connecting rods and the inner walls of the opposite ends of the two cavities respectively. Activity slots are provided at both the left and right ends of the lower surface of the box body. The bottom ends of the connecting rods are fixed with clamping plates. A plurality of damping blocks are fixed to the opposite ends of the two clamping plates. The fixture also includes clamping plates welded to the tops of the left and right ends of the hoisted section steel. Card slots are provided at the tops of the opposite ends of the two clamping plates. A slide rail is fixed at the center of the bottom end of the box body. Two movable blocks are slidably connected to the bottom end of the slide rail. Support rods are fixed to the bottom ends of the movable blocks. Electromagnets are fixed to the bottoms of the opposite ends of the two support rods. Air inlet interfaces communicated with the cavities are fixed to both the left and right ends of the box body.

[0008] Furthermore, a plurality of lifting lugs are fixed to the top surface of the box body, and pressure gauges corresponding to the cavities are fixed to both the left and right ends of the top surface of the box body.

[0009] Furthermore, the bottom end of the clamping plate penetrates through the activity slot, and the clamping plate is slidably connected with the activity slot.

[0010] Furthermore, the box body is a hollow cylindrical box body. A plurality of trapezoidal slots are provided at the opposite ends of the two clamping plates. The damping blocks are fixed in the trapezoidal slots.

[0011] Furthermore, a control valve is fixed to the air inlet interface. A T-shaped sliding slot is provided at the bottom end of the slide rail. The movable block is a T-shaped movable block, and the top end of the movable block is slidably connected with the T-shaped sliding slot.

[0012] Furthermore, the clamping plate is located inside the card slot. The damping block is a vulcanized rubber damping block, and the cross section of the damping block is trapezoidal.

[0013] Furthermore, the calibration and installation mechanism includes a pre-embedded box pre-embedded in the installation surface. Pre-embedded blocks are fixed to the peripheries of the outer surface of the pre-embedded box. Adjusting jacks are placed around the bottom wall of the inner cavity of the pre-embedded box. Output shafts penetrating to the outside of the pre-embedded box are slidably connected inside the outer surfaces of the adjusting jacks. The tops of the four output shafts are in contact with an adjusting plate. A cushion block is abutted between the bottom end of the adjusting plate and the top end of the pre-embedded box. Reinforcing plates are fixed to both the left and right ends of the pre-embedded box. The calibration and installation mechanism also includes mounting plates welded and fixed to the bottoms of the front and rear ends of the hoisted section steel.

[0014] Furthermore, the bottom end of the mounting plate is fixed to the adjusting plate and the pre-embedded box by bolts. The adjusting plate is located between the two reinforcing plates. The reinforcing plates are fixed to the hoisted section steel by bolts. Scale marks are coated on the outer surface of the output shaft.

[0015] The construction method for hoisting profiled steel includes the following steps:

[0016] S1. Before hoisting the profiled steel, drive the output shaft to move by adjusting the jack, adjust the height of the output shaft, and perform precise calibration in cooperation with the scale markings, and make the adjusting plate in a horizontal state to ensure that the hoisted profiled steel is in a vertical state after installation;

[0017] S2. Then move the fixture to the end face of the hoisted profiled steel, inject compressed air into the cavity through the air inlet interface to make the slider move, and then squeeze the return spring to contract, so that the two clamping plates clamp the side of the hoisted profiled steel, and at the same time the clamping plate is in the clamping groove;

[0018] S3. Secondly, move the support rod to make the movable block move back and forth in the slide rail, and fit the electromagnet to the hoisted profiled steel. The electromagnet adsorbs the hoisted profiled steel to achieve double limit for the hoisted profiled steel, and hoist the hoisted profiled steel under the cooperation of the hoisting equipment and the steel wire rope;

[0019] S4. Finally, vertically hoist the hoisted profiled steel onto the adjusting plate in a horizontal state, and then install and fix the hoisted profiled steel through the mounting plate, reinforcing plate and cushion block. After the fixing is completed, the hoisted profiled steel can also be finely adjusted by the jack.

[0020] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0021] 1. The deepened structure and construction method for hoisting profiled steel adopt a newly designed fixture structure to fix the hoisted profiled steel by means of double clamping and limiting to meet the vertical hoisting requirements of the hoisted profiled steel, improve the safety of the hoisted profiled steel during hoisting, and there is no need to weld multiple lifting lugs on the profiled steel to ensure the integrity of the profiled steel. The overall safety is good and the hoisting efficiency is high, which can meet the hoisting requirements of different types of large profiled steel.

[0022] 2. The deepened structure and construction method for hoisting profiled steel set a calibration and installation mechanism between the hoisted profiled steel and the installation surface. Compared with the traditional cable-type calibration method, there is no need to calibrate the profiled steel itself, and the safety and accuracy are guaranteed. At the same time, rapid fine adjustment and calibration before and during the hoisting of the hoisted profiled steel can be carried out.

[0023] 3. The deepened structure and construction method for hoisting profiled steel adopt the method of first calibrating, then hoisting and calibrating during installation to hoist the profiled steel, which can effectively improve the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1 , in the deepening structure of the section steel hoisting construction in this embodiment, it includes an installation surface 1 and a hoisting section steel 2. The hoisting section steel 2 is perpendicular to the upper part of the installation surface 1. A calibration installation mechanism 3 is provided between the installation surface 1 and the hoisting section steel 2, and a fixture 4 is provided above the hoisting section steel 2.

[0033] Please refer to Figures 2 - 4, to meet the lifting requirements of the profiled steel, the fixture 4 in this embodiment is used to clamp and lift the lifted profiled steel 2. The fixture 4 includes a box body 401 located at the top of the lifted profiled steel 2. The box body 401 is a cylindrical box body. A plurality of lifting lugs are fixed on the top surface of the box body 401 for connecting with steel wire ropes. Cavities 402 are opened at both the left and right ends of the box body 401. Pressure gauges corresponding to the cavities 402 are fixed at both the left and right ends of the top surface of the box body 401 to facilitate observing the pressure in the cavities 402. A slider 403 is slidably connected inside the cavity 402. A connecting rod 404 is fixed at one end of the two sliders 403 facing each other. A return spring 405 is fixed between one end of the two connecting rods 404 facing each other and the inner wall of one end of the two cavities 402 facing each other. Activity slots 406 are opened at both the left and right ends of the lower surface of the box body 401. The bottom end of the connecting rod 404 is fixed with a clamping plate 407. A plurality of damping blocks 408 are fixed at one end of the two clamping plates 407 facing each other. The fixture 4 further includes clamping plates 409 welded to the top of both the left and right ends of the lifted profiled steel 2. A clamping groove 410 is opened at the top of one end of the two clamping plates 407 facing each other. Air inlet interfaces 415 communicating with the cavities 402 are fixed at both the left and right ends of the box body 401. A control valve is fixed on the air inlet interface 415. Compressed air is used to squeeze the slider 403 to move, and the return spring 405 drives the movement of the activity slot 406, thereby driving the clamping plate 407 to move, so as to clamp the two sides of the lifted profiled steel 2.

[0034] Among them, the bottom end of the clamping plate 407 penetrates through the activity slot 406, and the clamping plate 407 is slidably connected with the activity slot 406, which facilitates the movement of the slider 403 to drive the clamping plate 407 to move.

[0035] In addition, a slide rail 411 is fixed at the center of the bottom end of the box body 401. Two movable blocks 412 are slidably connected to the bottom end of the slide rail 411. A support rod 413 is fixed at the bottom end of the movable block 412. Electromagnets 414 are fixed at the bottom of one end of the two support rods 413 facing each other. A T-shaped chute is opened at the bottom end of the slide rail 411. The movable block 412 is a T-shaped movable block, and the top end of the movable block 412 is slidably connected with the T-shaped chute. The movable block 412 slides in the T-shaped chute to adjust the positions of the two electromagnets 414. By adjusting the positions of the electromagnets 414, the lifted profiled steel 2 is adsorbed, further limiting the lifted profiled steel 2.

[0036] At the same time, the clamping plate 409 is located inside the clamping groove 410. The damping block 408 is a vulcanized rubber damping block, and the cross section of the damping block 408 is trapezoidal. A plurality of trapezoidal grooves are opened at one end of the two clamping plates 407 facing each other. The damping block 408 is fixed in the trapezoidal groove, which can further limit the lifted profiled steel 2 and improve the safety of hoisting.

[0037] In the fixture 4 of this embodiment, by injecting compressed air into the cavity 402, the clamping plate 407 is moved, so as to clamp the hoisted section steel 2, and then in cooperation with the movable electromagnet 414, double limit fixation of the hoisted section steel 2 can be achieved.

[0038] Please refer to Figures 5 - 6 , for vertical correction of the section steel. The correction and installation mechanism 3 in this embodiment includes a buried box 301 buried and installed in the installation surface 1. Buried blocks 302 are fixed around the outer surface of the buried box 301. Adjusting jacks 303 are placed around the inner bottom wall of the buried box 301. An output shaft 304 that penetrates to the outside of the buried box 301 is slidably connected inside the outer surface of the adjusting jack 303. A scale mark is coated on the outer surface of the output shaft 304. The tops of the four output shafts 304 are attached to an adjusting plate 305. A cushion block 306 is abutted between the bottom end of the adjusting plate 305 and the top end of the buried box 301. Reinforcing plates 307 are fixed to the left and right ends of the buried box 301. The adjusting plate 305 is located between the two reinforcing plates 307. The reinforcing plate 307 and the hoisted section steel 2 are fixed by bolts. The correction and installation mechanism 3 further includes a mounting plate 308 welded and fixed to the bottoms of the front and rear ends of the hoisted section steel 2. The bottom end of the mounting plate 308 is fixed to the adjusting plate 305 and the buried box 301 by bolts.

[0039] In the correction and installation mechanism 3 of this embodiment, by correcting the adjusting plate 305 located above the buried box 301, and during correction, the output shaft 304 can be rotated and precisely corrected in cooperation with the scale mark, so as to achieve vertical correction of the hoisted section steel 2 without the need to correct the hoisted section steel 2.

[0040] It should be noted that a movable door is hinged at a position above the installation surface 1 on the front side of the buried box 301. After the adjusting jack 303 is used up, the adjusting jack 303 can be taken out of the buried box 301. Finally, concrete is poured into the buried box 301 to improve the overall strength of the buried box 301.

[0041] Please refer to again Figures 1 - 6 , the section steel hoisting construction method in this embodiment includes the following steps:

[0042] S1. Before hoisting the hoisted section steel 2, drive the output shaft 304 to move through the adjusting jack 303, adjust the height of the output shaft 304, and precisely correct it in cooperation with the scale mark, and make the adjusting plate 305 in a horizontal state to ensure that the hoisted section steel 2 is in a vertical state after installation;

[0043] S2. Then, move the fixture 4 to the end face of the hoisted section steel 2, and inject compressed air into the cavity 402 through the air inlet interface 415, causing the slider 403 to move. Then, the compression spring 405 is squeezed and contracted, so that the two clamping plates 407 clamp the side of the hoisted section steel 2, and at the same time, the clamping plate 409 is in the clamping groove 410;

[0044] S3. Next, move the support rod 413, so that the movable block 412 moves back and forth in the slide rail 411, and fit the electromagnet 414 to the hoisted section steel 2. The electromagnet 414 adsorbs the hoisted section steel 2 to achieve double limit for the hoisted section steel 2. With the cooperation of the lifting equipment and the steel wire rope, the hoisted section steel 2 is lifted;

[0045] S4. Finally, vertically hoist the hoisted section steel 2 to the adjusting plate 305 in a horizontal state, and then install and fix the hoisted section steel 2 through the mounting plate 308, the reinforcing plate 307 and the cushion block 306. After the fixing is completed, the hoisted section steel 2 can also be finely adjusted by the jack 303.

[0046] It can be understood that before hoisting, the acceptance work of the components on site needs to be carried out, mainly including whether the quantity, type and specification of the components are consistent with the drawings, and whether the processing quality of the components meets the design requirements; whether the qualification certificates of the materials of each component are complete, and whether the material and various parameters of the materials are consistent with the design requirements; whether the factory certificates and self-inspection record materials of the components are complete, and the soil and floating rust on the surface of the hoisted section steel 2 are cleaned before hoisting. To prevent damage to the ground and the hoisted section steel 2 caused by dragging the hoisted section steel 2 on the ground during hoisting, sleepers should be padded under the hoisted section steel 2, and a climbing ladder should be tied to the hoisted section steel 2 before hoisting.

[0047] It can be understood that for the construction of the embedded parts under the hoisted section steel 2 in the installation surface 1, it is designed according to the distribution, shape and weight of the anchor bolts, and the bearing capacity of the supporting steel bracket is calculated and reviewed to ensure the safety, stability and deformation of the steel bracket meet the requirements. When constructing the bottom cushion steel reinforced concrete floor, steel plates are embedded at the vertical projection position of the steel column foot for the positioning and fixing of the embedded bolt steel bracket. According to the position of the positioning axis of each steel column determined by the positioning measurement; place the steel bracket system of the embedded anchor bolts, align the positioning line of the steel bracket system with the measurement positioning point, and fix it with the embedded iron in the precast concrete. After the bracket is fixed, re-measure and position, and pop up the positioning center line on the top surface of the steel bracket for the accurate fixing of the embedded bolts. On the fixed steel bracket, place the positioning template for the anchor bolts according to the positioning line, adjust and accurately position and then weld and fix it. Then, insert the embedded bolts into the bolt holes of the positioning template. After the steel bars are tied, accurately position and reinforce the position and elevation of the embedded bolts of the steel column again.

[0048] In addition, for the casting of the installation surface 1, the control lines (such as the basic axis or center line, etc.) of the anchor bolt installation positions and the positioning lines of the top surfaces of the angle steels on the anchor bolts should be surveyed and set. The longitudinal and transverse center lines should be pre-drawn on the angle steels of the anchor bolts. During the embedding, find the longitudinal and transverse control lines and make them coincide with the basic axis of the measurement positioning. After the installation, carry out the concrete pouring. Measures should be taken during the pouring to ensure the position and size of the embedded bolts. Adjust the elevation of the embedded plate by adjusting the nuts at the lower part of the embedded plate, measure the position and size of the embedded plate, and correct the deviation in time when found.

[0049] The working principle of the above embodiment is as follows:

[0050] 1. Connect the compressed air equipment to the air inlet interface 415, and then open the control valve to inject compressed air into the cavity 402. The pressure gauge is set to observe the pressure in the cavity 402. The compressed air drives the two sliders 403 and the connecting rod 404 to squeeze the return spring 405 to move relatively, thereby driving the clamping plate 407 to move and clamping both the left and right ends of the hoisted section steel 2. The clamping plate 409 moves into the clamping groove 410, and then cooperates with the damping block 408 to improve the stability during clamping. Secondly, move the position of the movable block 412 so that the electromagnet 414 adsorbs the hoisted section steel 2 to further fix the hoisted section steel 2. Finally, cooperate with the fixture 4 through the hoisting equipment to lift the hoisted section steel 2.

[0051] 2. Before hoisting the hoisted section steel 2, the output shaft 304 can be lifted by adjusting the jack 303 to adjust the height of the output shaft 304. Observe the scale marks on the surface of the output shaft 304 to accurately adjust the output shaft 304. After the adjusting plate 305 above the output shaft 304 is adjusted, install the cushion block 306, then hoist the hoisted section steel 2 above the adjusting plate 305, and install and fix it through the mounting plate 308 and the reinforcing plate 307. In addition, after the hoisted section steel 2 is installed, fine adjustment and correction can also be carried out to further improve the correction accuracy.
