Stirrups of corresponding heights need to be configured according to the project and different positions, or the height is adjusted by artificial pads, which leads to high project costs and also affects the progress and efficiency of construction to a certain extent. Therefore, it is necessary to provide a height-adjustable support stirrup that can solve the problem that the height of the support stirrup cannot be adjusted or is not flexible in adjustment in the prior art.

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please see attached Figure 1 To Attachment Figure 3A height-adjustable support stirrup comprises a stirrup body 1, a slide rail frame 2, a top support 3, a sliding locking assembly and a height adjustment assembly; the bottom of the leg of the stirrup body 1 is movably inserted in the slide rail frame 2, and the leg of the stirrup body 1 can be locked and connected to the slide rail frame 2 through the sliding locking assembly, and the bottom of the slide rail frame 2 is supported on the ground below the beam body 4; the top support 3 is connected to the top of the stirrup body 1 and can be lifted and lowered on the slide rail frame 2 through the height adjustment assembly, and the top support 3 is supported on the bottom of the beam body 4.

[0029] The stirrup body 1 can preferably be a triangular stirrup of the prior art. The stirrup body 1 can be made by welding a square steel pipe, and a top support 3 is installed on the top. The top support 3 selects channel steel of corresponding specifications according to the specifications of the main beam 4 to ensure stable support for the main beam 4.

[0030] According to the square steel specifications of the stirrup main body 1, square steel of corresponding specifications is selected for welding to form a bracket as the slide rail frame 2, and four legs of the stirrup main body 1 are correspondingly inserted into the slide rail frame 2 at the bottom. The four legs of the stirrup main body 1 can be telescopically adjusted relative to the slide rail frame 2, thereby meeting the different height setting requirements of different main beams 4.

[0031] Please see attached Figure 4 To Attachment Figure 6 The height adjustment assembly includes a fixed column 501, a movable column 502, a hand-cranked transmission mechanism and a pull rod locking mechanism; the lower end of the fixed column 501 is fixedly installed on the slide rail frame 2, the lower part of the movable column 502 is movably inserted into the upper part of the fixed column 501, and the upper end of the movable column 502 is fixedly connected to the bottom of the top support 3; the hand-cranked transmission mechanism and the pull rod locking mechanism are respectively installed on the fixed column 501 through the mounting plate 503, and are located on both sides of the movable column 502, the hand-cranked transmission mechanism is transmission-connected to one side of the movable column 502, and the pull rod locking mechanism can be clamped and fixed to the other side of the movable column 502.

[0032] The fixed column 501 and the movable column 502 can be made of square steel of two sizes. The fixed column 501 is welded to the stirrup body 1, and the movable column 502 can be raised and lowered relative to the fixed column 501 by plugging and telescoping.

[0033] The hand-crank transmission mechanism is used to control the small lifting and lowering of the movable column 502 and the top support 3 relative to the fixed column 501 and the slide rail frame 2, so as to meet the setting height accuracy requirements of the beam body 4. After the movable column 502 is adjusted in place, the movable column 502 is locked and fixed with the fixed column 501 through the pull rod locking mechanism to ensure that the top support 3 can reliably support the beam body 4.

[0034] Please see attached Figure 4 To Attachment Figure 6The hand-cranked transmission mechanism includes a rocker handle 504, a rocker 505, a transmission shaft 506, a first turntable 507 and a lifting screw 508; the rocker handle 504 is vertically connected to one end of the rocker 505, one end of the transmission shaft 506 is vertically connected to the other end of the rocker 505, and the rocker handle 504 and the transmission shaft 506 extend in opposite directions relative to the rocker 505 respectively; the first turntable 507 is rotatably arranged on the mounting plate 503 through a rotating bearing, one surface of the first turntable 507 is coaxially fixedly connected to the other end of the transmission shaft 506, and the lifting screw 508 is spirally arranged on the other surface of the first turntable 507 and is transmission-connected to the movable column 502.

[0035] Preferably, the first turntable 507 may include a fixed plate and a rotating plate which are connected to each other in a relatively rotatable manner via a rotating bearing. The fixed plate is mounted on the mounting plate 503 via bolts and nuts, and the rotating plate is fixedly connected to the transmission shaft via a coupling, so that the rotating plate can be driven to rotate via the rocker handle 504 via the rocker 505.

[0036] The lifting screw 508 is installed on the rotating disk of the first rotating disk 507. The lifting screw 508 is roughly an annular structure, with a smaller diameter at one end and a larger diameter at the other end, and the diameter gradually increases from the inside to the outside. When the lifting screw 508 rotates forward or reverse with the rotating disk of the first rotating disk 507, the transmission movable column 502 performs a lifting action due to the gradual change in diameter.

[0037] Due to the annular structure of the lifting screw 508 , the lifting screw 508 can expand the lifting range of the movable column 502 relative to the fixed column 501 through multiple rotations.

[0038] Please see attached Figure 7 The lifting screw 508 is evenly distributed with meshing teeth (not shown in the figure), and a first meshing rack 509 is formed on one side of the movable column 502. The lifting screw 508 is meshed and transmission-connected with the first meshing rack 509 through the meshing teeth.

[0039] Preferably, the lifting screw 508 and the first rotating disk 507 can be slightly tilted, so that the meshing teeth of the lifting screw 508 can be more fully meshed with the first meshing rack 509, and the lifting screw meshing teeth at other non-meshing positions will not interfere with the meshing transmission process. The transmission using meshing teeth can ensure the stability and controllability of the transmission process, and the transmission control accuracy is high.

[0040] Please see attached Figure 7The pull rod locking mechanism includes a pull rod 510, a second turntable 511 and a limiting tooth 512; the second turntable 511 is rotatably set on the mounting plate 503 by bolts and nuts, and the limiting tooth 512 is set on the arc end of the second turntable 511 close to the other side of the movable column 502; a second meshing rack 513 is formed on the other side of the movable column 502, so that the limiting tooth 512 can be matched and engaged in one of the tooth grooves of the second meshing rack 513.

[0041] The second rotating disk 511 can be installed on the mounting plate 503 by bolts and nuts, and is not locked after installation, so that the second rotating disk 511 can rotate. The pull rod 510 is used to hold and drive the second rotating disk 511 to rotate, so that the limiting clamping teeth 512 can be clamped to the second meshing rack 513, and then the bolts and nuts are locked to fix the second rotating disk 511, thereby ensuring the stable limiting of the second meshing rack 513, and further ensuring the locking and fixing of the movable column 502 on the fixed column 501.

[0042] After the lifting screw 508 rotates one circle, since the two ends of the lifting screw 508 are disconnected, the movable column 502 can be temporarily locked by the limit tooth 512, and then the lifting screw 508 continues to rotate. At this time, the lifting screw 508 and the first meshing rack 509 are disconnected and the movable column 502 will not fall.

[0043] Please see attached Figure 7 The two sides of the fixed column 501 are formed with openings 514 , so that the first meshing rack 509 and the second meshing rack 513 of the movable column 502 are exposed at the two openings 514 respectively.

[0044] The movable column 502 is inserted into the fixed column 501 to protect the first meshing rack 509 and the second meshing rack 513. The opening 514 is provided to ensure the transmission effectiveness of the first meshing rack 509 located inside the fixed column 501 and the lifting screw 508 located outside the fixed column 501, as well as the limiting effectiveness of the second meshing rack 503 located inside the fixed column 501 and the limiting tooth 513.

[0045] The inclination angle of the lifting screw 508 can be adaptively adjusted according to the depth of the opening 514, thereby ensuring the meshing transmission effect.

[0046] Please see attached Figure 8 The sliding locking assembly includes a sliding plate 601 and a latch buckle 602; the sliding plate 601 is installed on the leg of the stirrup body 1 along the length direction of the leg of the stirrup body 1, and a plurality of first positioning holes (not shown in the figure) are formed at intervals on the sliding plate 601; a second positioning hole (not shown in the figure) is formed on the top of the slide rail frame 2, and the latch buckle 602 is inserted into the second positioning hole and one of the first positioning holes.

[0047] The sliding plate 601 slides synchronously with the legs of the stirrup body 1. After the telescopic adjustment is in place, the second positioning hole is aligned with one of the first positioning holes, so that the latch buckle 602 is inserted into the second positioning hole and one of the first positioning holes to lock the stirrup body 1 and the slide rail frame 2. At the same time, the sliding plate 601 can also provide reinforcement at the opening of the legs of the stirrup body 1 to ensure the load-bearing capacity of the stirrup body.

[0048] Please see attached Figure 1 To Attachment Figure 8 , the method of using the utility model is:

[0049] A stirrup with a triangular structure is adopted, wherein two inverted V-shaped brackets are arranged in parallel and connected into a whole through a top connecting rod to form a stirrup body 1.

[0050] The top support 3 is arranged on the top connecting rod of the stirrup body 1 and connected to the hand-cranked transmission mechanism. The legs of the stirrup body 1, i.e., the four legs of the two inverted V-shaped brackets, are inserted into the four slide rails of the slide rail frame 2, and the four slide rails are placed on a construction surface such as a concrete surface below the beam body 4.

[0051] Holding the rocker handle 504 and driving the rocker 505 to rotate, the rocker 505 drives the lifting screw 508 to rotate synchronously through the transmission shaft 506. When the movable column 502 is located at the bottom of the fixed column 501, that is, the lifting adjustment range is the smallest, the first meshing rack 509 meshes with the smallest diameter end of the lifting screw 508. As the rocker 505 rotates, the lifting screw 508 rotates synchronously to the largest diameter end. Due to the increase in the diameter of the meshing part, the first meshing rack 509 is lifted upward to the top of the top support 3 and supported on the top of the beam body 4.

[0052] Pull the pull rod 510 to rotate the second rotating disk 511 , and make the limiting teeth 512 mesh with and clamp the second meshing rack 513 , and lock the bolts and nuts of the second rotating disk 511 , and lock the movable column 502 .

[0053] If the height of the beam body 4 is relatively high, the second meshing rack 513 can be temporarily clamped by the limiting clamping teeth 512 after the lifting screw 508 rotates one circle. Since the weight of the jacking support 3 is relatively light, the pull rod 510 can be manually fixed so that the limiting clamping teeth 512 can limit the second meshing rack 513 to prevent the movable column 502 from falling. Then continue to rotate the lifting bolt 508 to separate the large diameter end of the lifting bolt 508 from the first meshing rack 509, and the small diameter end of the lifting bolt 508 rotates to mesh with the first meshing rack 509 again. Pull 510 in the reverse direction to disengage the limiting clamping teeth 512 from the second meshing rack 513, release the limit, and continue to rotate the lifting screw 508, thereby continuing to lift the movable column 502.

[0054] The above operation is repeated until the movable column 502 is adjusted to the point where the jacking support 3 is pressed tightly against the bottom of the beam body 4 and reliably supports the beam body 4 .

[0055] As the top support 3 is lifted, the stirrup body 1 moves upward synchronously with the top support 3 relative to the slide rail frame 2, and the four legs move upward relative to the four slide rails. Insert the latch buckle 602 into the second positioning hole and the first positioning hole at the corresponding position, so that the four slide rails are respectively locked and fixed with the four legs of the stirrup body 1. The stirrup body 1 and the slide rail frame 2 are supported between the construction surface and the beam body 4, so that the beam body 4 is stably supported.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
