Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a jacking and sliding device for construction of a multi-span roof structure and a use method thereof. Background Art

[0002] The factory roof structure has multiple and large spans horizontally and is composed of multiple steel roof structures vertically. The traditional construction sequence is to hoist and assemble them into a single roof structure, and then assemble them one by one in a certain order. Although the above construction method is simple to operate, it has low construction efficiency and high requirements for the construction site.

[0003] Therefore, the engineering and technical personnel thought of constructing the multi-span roof structure by the sliding construction method in the prior art. This method is realized by setting components such as sliding tracks, clamping blocks, hydraulic rods and sliding shoes. Specifically, the clamping blocks are clamped on the sliding tracks, and then the hydraulic rods are extended to push the sliding shoes to move, thereby pushing the steel structure on the sliding shoes to a certain distance, and then the clamping blocks are released to retract the hydraulic rods, and then the next jacking operation can be performed. Therefore, the steel structure can be pushed to the designed position after multiple jacking operations, which has comprehensive advantages such as high construction quality, saving large equipment and construction land.

[0004] In the above-mentioned construction method, the clamping and disengaging process between the clamping block and the sliding track is a key factor affecting the efficiency of the sliding construction, and in the prior art, the clamping and disengaging process between the clamping block and the sliding track is usually operated manually, and the two cannot be automatically locked and disengaged during the sliding pushing process, which will affect the smoothness of the overall sliding construction and lead to the problem of relatively low overall construction efficiency.

[0008] Furthermore, a limit plate is provided on one side surface of the two baffles facing the closed end of the U-shaped groove, one end of the limit plate is fixed to the baffle, and the other end of the limit plate protrudes from the outer side surface of the baffle and points to the wedge-shaped stop block, and the upper surface of the baffle is flush with the lower surface of the wedge-shaped stop block.

[0009] Furthermore, a mounting groove is provided below the second through groove, and the mounting groove is arranged perpendicular to the middle of the first through groove. A plurality of return springs are provided on one end of the two baffles located in the mounting groove, and the two ends of the return springs are respectively fixed on the opposite sides of the two baffles.

[0010] Furthermore, the connecting rod is arranged in parallel in the second through groove.

[0011] Furthermore, annular end plates are provided on both ends of the first pin shaft, the diameter of the annular end plates is larger than the width of the sliding groove, and the outer surface of the first pin shaft is in sliding contact with the inner wall of the sliding groove.

[0012] Furthermore, both ends of the hydraulic rod are provided with connecting blocks, one end of the connecting block is sleeved on the first pin shaft, and the other end of the connecting block is rotatably connected to the sliding shoe through the second pin shaft.

[0013] Furthermore, elastic ropes are provided on both side surfaces of the mounting block facing the width direction of the slide rail, one end of the elastic rope is fixed to the mounting block, and the other end of the elastic rope is fixed to the slide shoe.

[0014] A method for using a jacking and sliding device for multi-span roof structure construction comprises the following steps:

[0015] S1, fixing a plurality of slide rails on a plane formed by a concrete beam and a concrete column, and the plurality of slide rails are arranged in parallel;

[0016] S2, then put the mounting block and the sliding shoe into the U-shaped groove of each slide rail, and then rotate the two ends of the hydraulic rod to connect to the mounting block and the sliding shoe respectively;

[0017] S3, hoisting and placing the roof structure to be installed on a number of sliding shoes;

[0018] S4, when the hydraulic rod is extended, the hydraulic rod first drives the first pin to slide in the sliding groove, drives the wedge-shaped push block to move, and when the wedge-shaped push block moves, it pushes the baffle to slide outward, so that the baffle contacts the end surface of the wedge-shaped block, thereby blocking the movement of the mounting block. When the first pin slides to the limit position, the hydraulic rod continues to extend, which pushes the slide to move in the slide rail, thereby pushing the roof structure to slide;

[0019] S5, when the hydraulic rod is extended to the maximum stroke, the hydraulic rod retracts. When the hydraulic rod retracts, the hydraulic rod drives the wedge-shaped push block to reset, thereby losing the force on the baffle. Then, the hydraulic rod drives the mounting block to move in the slide rail toward the sliding shoe. During the movement, the wedge-shaped block contacts the baffle, causing the baffle to move toward the middle and reset.

[0020] S6. Repeat steps S4-S6 to continuously push and slide the roof structure, and then push and slide the roof structure to the installation position.

[0021] The beneficial effects of the present invention are:

[0022] (1) In the technical solution, the baffle plate and the wedge-shaped block are pushed to achieve the position-limiting operation by pushing the first pin shaft to move in the sliding groove in the early stage of the extension of the hydraulic rod. The advantage of this is that since the top thrust of the hydraulic rod is relatively large, the force acting on the wedge-shaped push block is relatively large, thereby having a better effect on limiting the sliding of the baffle plate. That is, in actual use, this method will not cause fatigue failure when locking, so it is more reliable to use (in the prior art, the block is pressed against the end of the wedge-shaped block by a spring, and the spring will fail or be fatigued after long-term use or being subjected to a large torque);

[0023] (2) The structure and concept of this technical solution are ingenious. The installation block and the slide rail are locked by pushing the hydraulic rod without manual operation, which can greatly improve the construction efficiency of the roof structure.

[0024] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1 to Figure 6As shown, a push-sliding device for multi-span roof structure construction of the present invention comprises a slide rail 1, a clamping block mechanism, a hydraulic rod 20 and a sliding shoe 23. A U-shaped groove 2 is provided in the middle of the length direction of the slide rail 1. A plurality of wedge-shaped stoppers 3 connected end to end are provided in the middle of two oppositely arranged side surfaces inside the U-shaped groove 2. The cross-sectional shape of the wedge-shaped stopper 3 is a right-angled trapezoid, that is, it is in a state of one end being higher than the other end. The clamping block mechanism comprises a mounting block 4. Part of the mounting block 4 is in sliding contact with the two oppositely arranged side surfaces of the U-shaped groove 2. It can be understood that a part of the mounting block 4 is located in the U-shaped groove 2, and a part is located in the The first avoidance groove 5 is provided on the surface of the mounting block 4 and the surface of the mounting block 4 in sliding contact with the U-shaped groove 2. The purpose of setting the first avoidance groove 5 is to prevent the sliding of the mounting block 4 from being blocked by the wedge-shaped stopper 3. Since part of the mounting block 4 is in sliding contact with the inner side of the U-shaped groove 2, the mounting block 4 will not deflect in the U-shaped groove 2. After the first avoidance groove 5 is set, the mounting block 4 will not contact the wedge-shaped stopper 3, and no sliding interference will occur. That is, it is not difficult to understand that the wedge-shaped stopper 3 is located in the first avoidance groove 5, and the mounting block 4 is on both sides of the width direction of the slide rail 1. A first through slot 7 is provided, and baffles 12 are provided inside both ends of the first through slot 7. The baffles 12 are slidably connected to the first through slot 7. The portion of the mounting block 4 located above the slide rail 1 is provided with a second through slot 6. The second through slot 6 is arranged perpendicular to the baffle 12, and the upper end of the baffle 12 is located in the second through slot 6. A wedge-shaped push block 15 is provided in the second through slot 6. The cross section of the wedge-shaped push block 15 is an isosceles trapezoid. The inclined surfaces on both sides of the wedge-shaped push block 15 are respectively in contact with the side surfaces of the two baffles 12 that are arranged opposite to each other. A connecting ear 9 is symmetrically provided on the outer side surface of one end of the mounting block 4. The middle of the connecting ear 9 A sliding groove 10 is provided, a first pin shaft 17 is provided in the sliding groove 10, a connecting rod 16 is provided on the wedge-shaped push block 15, one end of the connecting rod 16 is fixed to the wedge-shaped push block 15, and the other end of the connecting rod 16 is fixed to the first pin shaft 17; one end of the hydraulic rod 20 is rotatably connected to the middle part of the first pin shaft 17, and the other end of the hydraulic rod 20 is rotatably connected to the sliding shoe 23, the lower part of the sliding shoe 23 is located in the U-shaped groove 2, and is in sliding contact with the two opposite side surfaces of the U-shaped groove 2, and a second avoidance groove 24 is symmetrically provided on the sliding shoe 23, and the wedge-shaped stopper 3 is located in the second avoidance groove 24.

[0035] The working principle of the above technical solution is:

[0036] After the steel structure is hoisted and placed on the sliding shoe 23, the hydraulic rod 20 is controlled to extend, that is, when the hydraulic rod 20 is extended, due to the heavy weight of the steel structure, the end of the hydraulic rod 20 connected to the first pin shaft 17 first moves in the sliding groove 10 of the connecting ear 9 (it is not difficult to understand that the worker needs to press the mounting block 4 to prevent the mounting block 4 from sliding in the slide rail 1 under the push of the hydraulic rod 20), that is, the wedge-shaped push block 15 will be driven to move during the movement, that is, the inclined surfaces on both sides of the wedge-shaped push block 15 will push the baffle 12 to move outward, that is, when the baffle 12 moves out of the first through groove 7, the end of the baffle 12 abuts against the end of the higher end of the wedge-shaped block 3, so the movement of the first pin shaft 17 will be restricted, that is, at this time, the continued extension of the hydraulic rod 20 will push the sliding shoe 23 to move on the slide rail 1, thereby pushing the steel structure to move, thereby achieving the effect of pushing and sliding;

[0037] When the hydraulic rod 20 is extended to the maximum stroke, the hydraulic rod 20 contracts. When the hydraulic rod 20 contracts, the hydraulic rod 20 drives the wedge-shaped push block 15 to reset, thereby losing the force on the baffle 12. Then the hydraulic rod 20 drives the mounting block 4 to move in the direction of the sliding shoe 23 in the slide rail 1. During the movement, the wedge-shaped block 3 contacts the baffle 12, causing the baffle 12 to move toward the middle and reset, so that the next pushing and sliding operation can be performed.

[0038] Therefore, in the present technical solution, the hydraulic rod 20 is extended in the early stage to drive the first pin shaft 17 to move in the sliding groove 10, so as to push the baffle plate 12 and the wedge-shaped block 3 to achieve the tight limit operation. The advantage of this is that since the pushing force of the hydraulic rod 20 is relatively large, the force acting on the wedge-shaped push block 15 is relatively large, which can effectively lock the position of the baffle plate 12. Therefore, in actual use, this method is more reliable, and there will be no poor locking effect between the mounting block 4 and the slide rail 1, which will lead to the safety hazard of the two being separated during the pushing process.

[0039] In an practicable manner, a limit plate 13 is provided on one side of the two baffles 12 facing the closed end of the U-shaped groove 2, one end of the limit plate 13 is fixed on the baffle 12, and the other end of the limit plate 13 protrudes from the outer side of the baffle 12 and points to the wedge-shaped stopper 3, and the upper surface of the baffle 12 is flush with the lower surface of the wedge-shaped stopper 3. It is not difficult to understand that when the baffle 12 slides outward, it will drive the limit plate 13 to slide outward together, that is, when the baffle 12 slides to the specified position, the limit plate 13 is located below the wedge-shaped stopper 3, and the vertical movement of the limit block is blocked. Therefore, the setting of the limit block can ensure the relative position of the mounting block 4 in the U-shaped groove 2, so that it will not have the problem of vertical separation during the force process, so it is safer and more reliable to use.

[0040] In an practicable manner, a mounting groove 8 is provided below the second through groove 6, and the mounting groove 8 is provided perpendicular to the middle of the first through groove 7. A plurality of return springs 14 are provided on one end of the two baffles 12 located in the mounting groove 8, and the two ends of the return spring 14 are respectively fixed on the opposite sides of the two baffles. The return spring 14 can quickly drive the baffle 12 to return to its original position after the baffle 12 loses its force, thereby improving the sliding effect of the baffle in the U-shaped groove 2.

[0041] In an practicable manner, the connecting rod 16 is arranged in parallel in the second through slot 6 . The advantage of the parallel arrangement is that a horizontal torque can be applied to the wedge-shaped push block 15 , thereby improving the sliding effect of the wedge-shaped push block 15 .

[0042] In one feasible manner, annular end plates 19 are provided at both ends of the first pin shaft 17, the diameter of the annular end plates 19 is greater than the width of the sliding groove 10, and the outer surface of the first pin shaft 17 slides in contact with the inner wall of the sliding groove 10 to prevent the first pin shaft 17 from detaching from the sliding groove 10, while also guiding the movement of the first pin shaft 17 to avoid tilting problems.

[0043] In one practicable manner, connecting blocks 18 are provided at both ends of the hydraulic rod 20. The connecting block 18 at one end is sleeved on the first pin shaft 17, and the connecting block 18 at the other end is rotatably connected to the fixed block 22 symmetrically arranged on the sliding shoe 23 through the second pin shaft 21.

[0044] In an practicable manner, elastic ropes 11 are provided on both side surfaces of the mounting block 4 facing the width direction of the slide rail 1 , one end of the elastic rope 11 is fixed to the mounting block 4 , and the other end of the elastic rope 11 is fixed to the slide shoe 23 .

[0045] The purpose of setting the elastic rope 11 is to provide an initial limiting torque for the movement of the mounting block 4, that is, when the hydraulic rod 20 is initially extended, due to the existence of the elastic rope 11, a reverse force is provided to the movement of the mounting block 4, that is, the hydraulic rod 20 will not push the mounting block 4 to move in the slide rail 1, but will drive the first pin shaft 17 to slide in the sliding groove 10, and then push the baffle 12 to perform a limiting operation, and then in the subsequent movement process, it will drive the elastic rope 11 to deform, thereby realizing the promotion of the steel structure.

[0046] A method for using a jacking and sliding device for multi-span roof structure construction comprises the following steps:

[0047] S1, fixing a plurality of slide rails 1 on a plane formed by a concrete beam and a concrete column, and the plurality of slide rails 1 are arranged in parallel;

[0048] S2, then put the mounting block 4 and the sliding shoe 23 into the U-shaped groove 2 of each slide rail 1, and then rotate the two ends of the hydraulic rod 20 to connect to the mounting block 4 and the sliding shoe 23 respectively;

[0049] S3, hoisting and placing the roof structure to be installed on a plurality of sliding shoes 23;

[0050] S4, when the hydraulic rod 20 is extended, the hydraulic rod 20 first drives the first pin shaft 17 to slide in the sliding groove 10, and drives the wedge-shaped push block 15 to move. When the wedge-shaped push block 15 moves, it pushes the baffle plate 12 to slide outward, so that the baffle plate 12 contacts the end surface of the wedge-shaped block 3, and then blocks the movement of the mounting block 4. When the first pin shaft 17 slides to the limit position, the hydraulic rod 20 continues to extend, that is, it pushes the slide to move in the slide rail 1, and then pushes the roof structure to slide;

[0051] S5, after the hydraulic rod 20 is extended to the maximum stroke, the hydraulic rod 20 is retracted. When the hydraulic rod 20 is retracted, the hydraulic rod 20 drives the wedge-shaped push block 15 to reset, thereby losing the force on the baffle 12, and then the hydraulic rod 20 drives the mounting block 4 to move in the slide rail 1 toward the sliding shoe 23. During the movement, the wedge-shaped block 3 contacts the baffle 12, so that the baffle 12 moves to the middle and resets;

[0052] S6. Repeat steps S4-S6 to continuously push and slide the roof structure, and then push and slide the roof structure to the installation position.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
