Description

Technical Field

[0001] The present invention relates to the technology of prefabricated construction, and specifically to a corrugated pipe fixing tooling and construction method. Background Art

[0002] As is well known, prefabricated buildings refer to buildings assembled at the construction site with prefabricated components made in factories. Promoting prefabricated buildings can not only greatly speed up the construction speed, improve the quality of construction projects, save labor, but also significantly reduce building energy consumption.

[0003] The deficiencies of the prior art are that the most commonly used connection form between precast columns at present is the grouting sleeve connection technology. The factory fixes the corrugated pipes through steel bars, and each corrugated pipe needs to be tied or welded in both horizontal and vertical directions. When the position of the corrugated pipe needs to be changed, the welded steel bars need to be ground off, which not only wastes materials but also labor costs. Moreover, this tying or welding requires high labor costs, wastes materials, and has low labor efficiency. Therefore, there is an urgent need for a tooling and construction method that can quickly fix corrugated pipes. Summary of the Invention

The slider is fixedly connected to the top of one side of the movable seat. When the slider drives the movable seat to move to the extreme position in the slide rail, a cross-shaped cooperation buckle fixing component is formed between the two groups of fixed seats and movable seats outside the fixing ring to fix the horizontal steel bar, the vertical steel bar, and the corrugated pipe.

[0010] As a further description of the above technical solution: The buckle fixing assembly includes rotating grooves opened at one end of the bottoms of the fixed seat and the movable seat. A rotating block is rotatably connected in the rotating grooves through bearings. One end of the rotating block is fixedly connected with a limiting gear. The two sides of the bottom of the limiting gear are detachably meshed with limiting rods. The bottom ends of the limiting rods are rotatably connected to the inner ends of the clamping plates through torsion spring shafts. A contact ring is rotatably installed in the middle of the bottom ends of the two groups of limiting rods. The surface of the contact ring is fixedly connected with a knob through a transmission rod.

The bottom ends of the telescopic rods penetrate through both sides of the fixed ring and are movably inserted into the slots opened at the top of the inner part of the fixed seat. The inner side walls of the slots are connected to the bottom ends of the telescopic rods through compression springs.

[0012] As a further description of the above technical solution: The buckle fixing assembly further includes a sliding groove opened at the bottom of the bottom end of the telescopic rod. Multiple adjacent limiting grooves are opened at the bottom of the sliding groove. The top end of a contact rod is slidably connected in the sliding groove. The bottom end of the contact rod is movably inserted into the top of the clamping groove opened in the fixed seat through a limiting spring.

[0013] As a further description of the above technical solution: Clamping grooves are opened at the bottoms of the fixed seat and the movable seat. The clamping plates cooperate with the clamping grooves to clamp and fix the horizontal steel bars and vertical steel bars.

[0024] 2. Material saving: Compared with the traditional welding fixing method, there is no need to grind and weld the steel bars when changing the position of the corrugated pipe, reducing the waste of materials and the construction cost.

[0025] 3. Adapt to various installation scenarios: The position of the movable seat on the outer side of the fixing ring is adjustable. For different steel bar settings of the corrugated pipe, such as only having steel bars on both sides or having steel bars all around, it can respectively realize the clamping and fixing of steel bars with different layouts by fitting against the fixing seat and the movable seat, or sliding the movable seat to form a cross-shaped structure.

[0026] 4. Reasonable structure design: The snap-fastening fixing component has a clever structure. For example, the inclined plate and inclined groove design uses the self-size of the corrugated pipe to squeeze the clamping ring, and the telescopic rod cooperates with the compression spring, the limit groove and the resisting rod to realize the fixing of the position of the clamping ring, and the height difference of the clamping groove can adapt to the height difference of the cross installation of the steel bars, and the magnetic strip enhances the connection stability of the fixing seat and the movable seat.

[0044] In another embodiment provided by the present invention, the snap fixing assembly also includes a clamping ring 2 movably inserted on both sides of the fixing ring 1, the bottom end of the clamping ring 2 is fixedly connected to a telescopic rod 3, and the bottom of one end of the telescopic rod 3 connected to the clamping ring 2 is provided with an inclined plate 17 with an isosceles trapezoidal cross-section, the inclined surface of the inclined plate 17 is recessed inwardly with an arc-shaped inclined groove 19 that fits the outer wall of the corrugated tube 27, the bottom end of the telescopic rod 3 passes through both sides of the fixing ring 1 and is movably inserted in a slot 15 opened at the top of the fixing seat 13, and the inner wall of the slot 15 is connected to the bottom end of the telescopic rod 3 through a compression spring 16.

[0045] In another embodiment provided by the present invention, the snap-fit fixing assembly also includes a slide groove 18 opened at the bottom of the bottom end of the telescopic rod 3, and a plurality of adjacent limit grooves 20 are opened at the bottom of the slide groove 18. The slide groove 18 is slidably connected to the top of the resistance rod 4, and the bottom end of the resistance rod 4 is movably inserted into the top of the clamping groove 5 opened in the fixing seat 13 through a limit spring 30.

[0046] In another embodiment provided by the present invention, clamping grooves 5 are formed in the inner bottoms of the fixed seat 13 and the movable seat 12. The clamping plates 8 are fitted in the clamping grooves 5 to clamp and fix the transverse steel bars 29 and the longitudinal steel bars 28.

[0047] In another embodiment provided by the present invention, the limiting groove 20 is provided with a conical cross-section and is adapted to the shape and size of the top end of the abutting rod 4. There is a height difference between the clamping grooves 5 formed in the inner bottoms of the fixed seat 13 and the movable seat 12 to accommodate the height difference generated when the transverse steel bars 29 and the longitudinal steel bars 28 are cross-mounted and fixed.

[0048] In another embodiment provided by the present invention, magnetic attraction strips 14 are arranged on the side where the fixed seat 13 and the movable seat 12 are in contact to magnetically fix the fixed seat 13 and the movable seat 12.

[0049] In another embodiment provided by the present invention, preferably, a construction method of a corrugated pipe 27 fixing tooling is as follows:

[0050] S1: Fit or split the two groups of movable seats 12 and the fixed seat 13 according to the positions of the transverse steel bars 29 and the longitudinal steel bars 28 arranged on the outer side of the corrugated pipe 27.

[0051] S2: Rotate the knob 10 to release the restriction on the rotation direction of the limiting gear 21, and turn the clamping plate 8 downward to hang down to open the clamping groove 5.

[0052] S3: Socket the fixing ring 1 from the top end of the corrugated pipe 27 downward to the connection part of the transverse steel bars 29 and the longitudinal steel bars 28.

[0053] S4: When the fixing ring 1 is inserted into the connection part of the transverse steel bars 29 and the longitudinal steel bars 28, insert the fixed seat 13 and the movable seat 12 into the clamping groove 5.

[0054] S5: Reverse-rotate the knob 10 to adjust the restriction on the rotation direction of the limiting gear 21. After turning the clamping plate 8 upward to fit against the bottoms of the fixed seat 13 and the movable seat 12, then rotate the knob 10 to fix the position of the clamping plate 8 to clamp and fix the transverse steel bars 29 and the longitudinal steel bars 28.

[0055] During use, the factory fixes the corrugated pipes 27 with steel bars. Each corrugated pipe 27 needs to be fixed in both horizontal and vertical directions. The fixing ring 1 is socketed on the outer side of the corrugated pipe 27, and the position of the movable seat 12 outside the fixing ring 1 is adjusted according to requirements. There are two adjustment methods:

[0056] The first type: When the transverse steel bars 29 or longitudinal steel bars 28 are only arranged on both sides of the corrugated pipe 27, it is only necessary to fit the fixed seats 13 and the movable seats 12 arranged on both sides of the fixing ring 1 and fix them by magnetic attraction using the magnetic strip 14, and the movable seat 12 and the fixed seat 13 clamp and fix the transverse steel bars 29 or longitudinal steel bars 28 on both sides of the corrugated pipe 27;

[0057] The second type: When the transverse steel bars 29 and longitudinal steel bars 28 are arranged around the corrugated pipe 27 at the same time, the movable seats 12 slidably arranged on both sides of the fixing ring 1 through the slide rails 6 and the sliders 7 are rotated outwards to both sides, so that a cross shape is formed between the two groups of movable seats 12 and the fixed seats 13, so that the movable seat 12 clamps and fixes the transverse steel bars 29, and the fixed seat 13 clamps and fixes the longitudinal steel bars 28.

[0058] When fixing the corrugated pipe 27 with the transverse steel bars 29 and the longitudinal steel bars 28, when the fixing ring 1 is sleeved downwards from the top of the corrugated pipe 27, when the fixing ring 1 is inserted downwards from the top of the corrugated pipe 27, due to its own size, the corrugated pipe 27 will contact the inclined plate 17 of the connecting clamping ring 2 arranged at the bottom of the top end of the telescopic rod 3. The two sides of the top end of the corrugated pipe 27 slide and abut against the inclined grooves 19 on the surface of the inclined plate 17. One end of the inclined groove 19 in contact with the clamping ring 2 protrudes outwards compared with the bottom end of the inclined groove 19. Therefore, when the corrugated pipe 27 contacts the bottom end of the inclined groove 19, the corrugated pipe 27 slides upwards along the surface of the inclined groove 19 and squeezes to drive the clamping ring 2 to be squeezed outwards. The clamping ring 2 slides the telescopic rod 3 connected to the outside of the clamping ring 2 to both sides inside the clamping ring 2 due to the limitation of the own size of the corrugated pipe 27. During the sliding process, the telescopic rod 3 outside the clamping ring 2 is contracted into the slot 15 opened at the inner top of the fixed seat 13 fixed on both sides of the fixing ring 1. When the telescopic rod 3 is inserted into the slot 15, the compression spring 16 is compressed;

[0059] After the corrugated pipe 27 squeezes the clamping ring 2 to the maximum extent due to its own size and then slides downwards and is inserted, when the fixing ring 1 slides down to the connection between the corrugated pipe 27 and the transverse steel bars 29 and the longitudinal steel bars 28, at this time, the upper surface of the longitudinal steel bar 28 contacts the bottom end of the contact rod 4 movably inserted at the top of the clamping groove 5 opened in the fixed seat 13, and the top end of the contact rod 4 is inserted into the slot 15. During the movement of the telescopic rod 3, the top end of the contact rod 4 slides in the chute 18 as the telescopic rod 3 is inserted, and after the bottom end of the contact rod 4 is resisted by the longitudinal steel bar 28, the top end of the contact rod 4 is correspondingly inserted into the limit groove 20 opened at the inner bottom of the chute 18, so as to fix the position of the telescopic rod 3, realize the fixation of the positions of the two groups of clamping rings 2, and fix the clamping force of the clamping ring 2 on the corrugated pipe 27;

[0060] After inserting the horizontal steel bar 29 and the vertical steel bar 28 into the clamping groove 5 opened at the inner bottom of the fixed seat 13 and the movable seat 12, at this time, the clamping plates 8 rotatably installed at the bottoms of the fixed seat 13 and the movable seat 12 will droop downward due to the action of gravity. At this time, only need to rotate the knob 10. Through the knob 10, the limiting rod 26 arranged on one side of the limiting gear 21 is limited by the contact ring 25 through the transmission rod 23, and the rotation direction of the limiting gear 21 is limited. At this time, the limiting gear 21 in the right fixed seat 13 can only rotate clockwise and cannot rotate counterclockwise, while the limiting gear 21 in the left fixed seat 13 can only rotate counterclockwise and cannot rotate clockwise. The same is true for the clamping plates 8 rotatably installed at the bottom of the movable seat 12;

[0061] The installation between the corrugated pipe 27 and the horizontal steel bar 29 and the vertical steel bar 28 can be completed by clamping and fixing the horizontal steel bar 29 and the vertical steel bar 28 inserted into the clamping groove 5 through the clamping plates 8 in cooperation with the fixed seat 13 and the movable seat 12;

[0062] When it is necessary to disassemble the fixing ring 1, rotate the knob 10 in the reverse direction to switch the contact of the contact ring 25 with the limiting rod 26 on the other side, so as to switch the rotation of the limiting gear 21 in the opposite direction. Then the clamping plate 8 can be drooped downward by rotating the clamping plate 8 in the rotating groove 11 through the rotating block 9, so as to release the clamping of the horizontal steel bar 29 and the vertical steel bar 28. Slide the fixing ring 1 upward, so as to release the contact of the horizontal steel bar 29 and the vertical steel bar 28 with the bottom end of the contact rod 4. The contact rod 4 slides downward under the reset action of the limiting spring 30, so as to pull out the top end of the contact rod 4 from the limiting groove 20 to release the limit on the telescopic rod 3. Then, under the action of the compression spring 16, the limit on the telescopic rod 3 can be released, and the fixing ring 1 can be removed from the outside of the corrugated pipe 27;

[0063] When the knob 10 drives the contact ring 25 to switch the contact action on the limiting rod 26 through the transmission rod 23, the other set of limiting rods 26 will be reset under the action of the reset spring 22 and the bottom end torsion spring rotating shaft 24. And when the limiting rod 26 is not under any contact effect, it will be separated from the limiting gear 21 and will not produce any contact restriction on the rotation of the limiting gear 21.

[0064] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
