[0002] In the construction of precast beams, temporary support frames are crucial equipment for ensuring the stability of precast beam hoisting, positioning, and installation, and are widely used in building and other engineering fields. Traditional temporary support frames at the ends of precast beams mostly adopt a fixed structure design, which suffers from poor height adjustment flexibility and difficulty in adapting to the support requirements of precast beams of different specifications. Adjusting the height often requires disassembly and reassembly, increasing labor time and potentially leading to a decrease in structural stability due to repeated disassembly and reassembly. There is an urgent need in engineering for a temporary support frame at the ends of precast beams that is height-adjustable, structurally stable, and easy to operate, to meet the requirements of modern construction for safety, efficiency, and adaptability.

[0003] Utility model CN219864255U provides a precast beam support frame, including a frame body and a support plate that matches the precast beam; the support plate is disposed at the top of the frame body; the frame body includes a telescopic unit connected to the support plate, the telescopic unit including a rectangular frame structure composed of multiple crossbars and multiple telescopic components, the longitudinal length of the telescopic components being adjustable. Although this solution provides a way to adjust the height of the precast beam support frame, it still suffers from problems such as inconvenient height adjustment and low adjustment efficiency.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Please refer to Figure 1-4This embodiment describes in detail an adjustable temporary support frame for the end of a precast beam, including a bearing base 101 and I-shaped support columns 102 symmetrically arranged on the top of the bearing base 101. A support column lifting end 401 is slidably sleeved on the top of the I-shaped support column 102. A support top plate 402 is provided on the top of the support column lifting end 401. Two intersecting diagonal braces 202 are also provided between the bearing base 101 and the support top plate 402. The intersection of the two diagonal braces 202 is hinged to a second movable hinge 203. The tops of the two diagonal braces 202 are hinged to the bottom of the support top plate 402 through a first movable hinge 201, and the bottoms of the two diagonal braces 202 are hinged to the top of the bearing base 101 through a first movable hinge 201. A locking buckle 204 is detachably installed in the middle of the second movable hinge 203. A hydraulic auxiliary lifting assembly 3 is also symmetrically arranged between the bearing base 101 and the support top plate 402. The support base 101 is a rectangular plate structure. I-shaped support columns 102 are symmetrically welded to the top two ends of the support base 101. The lifting end 401 of the support column is a groove structure adapted to the I-shaped support column 102. The support base 101, I-shaped support column 102 and lifting end 401 of the support column serve as the overall support foundation, providing a stable bottom bearing surface and vertical load support structure. At the same time, the lateral offset force is offset through a specific structural design, laying a stable bearing foundation for the entire support frame and ensuring that the overall structure is not easy to tilt during the support process. The top of the lifting end 401 of the support column is welded and fixed to the bottom of the support top plate 402. The intersection of the two diagonal bracing brackets 202 is connected to the second movable hinge 203. One end of the first movable hinge 201 is fixedly connected to the bearing base 101. There are four first movable hinges 201 in total. The four first movable hinges 201 are respectively fixedly installed on the inner sidewalls of the four corners on the opposite side of the two I-shaped support columns 102. The first movable hinges 201, the two diagonal bracing brackets 202, the second movable hinge 203 and the locking buckle 204 form a cross support structure, which can lock the support angle, effectively disperse the lateral torque borne by the overall structure, strengthen the stability of the main components, and avoid structural deformation caused by uneven force during the support process.

[0023] Furthermore, the hydraulic auxiliary lifting assembly 3 includes a hydraulic pump body 301 mounted on top of the support base 101. The top output end of the hydraulic pump body 301 is sealed to the bottom telescopic end of the hydraulic jack 302. The bottom outer wall of the hydraulic pump body 301 is hinged to a third movable hinge 303, and the other end of the third movable hinge 303 is fixedly connected to a hydraulic pump adjusting rod 304. The hydraulic auxiliary lifting assembly 3 provides precisely controllable power, enabling flexible adjustment of the support height. This allows operators to easily adjust the support position according to the height requirements of the precast beam. It is also easy to operate, stably pushing the relevant components to complete the lifting action, ensuring the accuracy and safety of height adjustment. The hydraulic auxiliary lifting assembly 3 can also be adjusted using a motor + electric hydraulic cylinder structure.

[0024] Preferably, the outer end of the hydraulic pump adjusting rod 304 is provided with an anti-slip grip. In order to prevent slippage when holding the hydraulic pump adjusting rod 304 and increase the comfort of holding it, an anti-slip grip is provided at the outer end of the hydraulic pump adjusting rod 304. The anti-slip grip can be made of silicone material and equipped with anti-slip texture or anti-slip raised dot structure.

[0025] Preferably, a triangular stabilizing bracket 103 is fixedly installed between the outer wall of the I-shaped support column 102 and the bearing base 101. In order to increase the stability between the I-shaped support column 102 and the bearing base 101, triangular stabilizing brackets 103 are welded to both ends of the outer wall of the I-shaped support column 102, and the bottom of the triangular stabilizing bracket 103 is welded and fixed to the top of the bearing base 101.

[0026] Preferably, the sidewall of the I-shaped support column 102 is provided with a plurality of limiting holes 104 evenly distributed along the height direction. The sidewall of the lifting end 401 of the support column is provided with a through hole that matches the limiting hole 104. The limiting hole 104 and the through hole on the lifting end 401 of the support column have the same diameter and are arranged in a one-to-one correspondence along the vertical direction. A limiting rod 405 is detachably installed in the limiting hole 104 and the corresponding through hole. In order to further increase the support stability, a plurality of limiting holes 104 are evenly distributed along the height direction on the sidewall of the I-shaped support column 102, and a through hole that matches the limiting hole 104 is provided on the sidewall of the lifting end 401 of the support column. The limiting rod 405 passes through the limiting hole 104 of the I-shaped support column 102 and the through hole of the lifting end 401 of the support column to achieve mechanical locking.

[0027] Preferably, the top of the supporting top plate 402 is bolted to the bottom of the arched top plate 403. Traditional support frames and the ends of precast beams are often rigidly connected, lacking a buffer or protective structure. The arched top plate 403 is bolted to the top of the supporting top plate 402.

[0028] Preferably, a rubber pad 404 is fixed to the top of the arched roof slab 403, and the top of the rubber pad 404 has anti-slip texture. During the support process, stress concentration can easily cause scratches and damage to the surface of the precast beam, or insufficient friction can cause the beam to slide, affecting the construction quality and efficiency. In order to increase the anti-slip properties of the arched roof slab 403 and buffer vibration, a rubber pad 404 is glued to the top of the arched roof slab 403, and the top of the rubber pad 404 has anti-slip texture.

[0029] In use, the main component 1 serves as the basic load-bearing structure, with the support base 101 providing the bottom support surface. The I-shaped support column 102 bears the vertical load, and the triangular stabilizing bracket 103 uses the principle of triangular stability to offset the lateral offset force of the I-shaped support column 102. The folding diagonal brace reinforcement component 2 is fixed to the main component 1 by four first movable hinges 201 respectively to the inner sidewalls of the four corners on the opposite side of two I-shaped support columns 102, two intersecting diagonal brace brackets 202, and second movable hinges 203, forming an "X-shaped" support. The locking buckle 204 locks the angle of the diagonal brace to disperse the lateral torque. In the hydraulic auxiliary lifting component 3, the hydraulic pump body 301 pushes the end support component 4 to move along the I-shaped support column 102 through the extension and retraction of the hydraulic push rod 302. The operator controls the pressure output by hinged to the hydraulic pump body 301 via the third movable hinge 303 using the hydraulic pump adjustment rod 304 with anti-slip grip. The grooved support column lifting end 401 of the end support component 4 slides and fits against the I-shaped support column 102 to form a slide rail connection. After adjusting to the preset height, the limiting rod 405 passes through the limiting hole 104 of the I-shaped support column 102 and the through hole of the support column lifting end 401 to achieve mechanical locking. When the end is supported, the support top plate 402 welded to the top of the support column lifting end 401 and the arched top plate 403 bolted to the support top plate 402 disperse the pressure. The anti-slip textured rubber pad 404 pasted on the top of the arched top plate 403 fits against the surface of the precast beam through elastic deformation, which not only prevents slippage but also buffers vibration. First, place the support base 101 of the main component 1 on a flat ground. Then, install the folding diagonal brace reinforcement component 2 and connect the first movable hinge 201, the diagonal brace bracket 202, and the second movable hinge 203 in sequence, and lock the buckle 204. Next, install the hydraulic auxiliary lifting component 3 and place the hydraulic pump body 301 at both ends of the support base 101. Fit it against the triangular stabilizing bracket 103 for positioning and bolt it to the outside of the I-shaped support column 102. Then, hinge the third movable hinge 303 to the hydraulic pump adjusting rod 304.

[0030] Finally, install the end support assembly 4, attach the support column lifting end 401, weld the support top plate 402, connect the arched top plate 403, and attach the rubber pad 404. Then, the operator holds the hydraulic pump adjusting rod 304 to drive the hydraulic jack 302 to extend and retract, causing the end support assembly 4 to rise along the I-shaped support column 102. Stop when the rubber pad 404 is close to the bottom surface of the precast beam end. Then, insert the limiting rod 405 to lock the height, and check the locking buckle 204, the bolts of the hydraulic pump body 301, and the fit of the rubber pad 404. After the precast beam is hoisted, make the beam end contact with the rubber pad 404, and regularly check the leakage of the hydraulic jack 302, the displacement of the limiting rod 405, and the deformation of the diagonal brace 202. Finally, pull out the limiting rod 405, reverse the operation of the hydraulic pump adjusting rod 304 to retract the hydraulic jack 302, and disassemble the end support assembly 4, the hydraulic auxiliary lifting assembly 3, and the folding diagonal brace reinforcement assembly 2 in sequence, and store the main assembly 1 to complete the process.
