A foundation reinforcement structure for a temporary steel support structure and its construction method

Abstract

This invention discloses a foundation reinforcement structure for a temporary support structure of a steel structure, relating to the field of steel structure technology. It includes a foundation, with multiple support components on top of the foundation, and multiple foot components on top of the support components. Each support component includes a bottom steel plate, which is fixed to the top of the foundation using anchor bolts. This invention fixes the foot components to the surface of a wooden pad by drilling holes in the foundation and fixing the support components to the foundation with anchor bolts, and then fixing a pressure plate to the surface of the bottom plate by tightening nuts. This increases the stability of the foot components. The wooden pad has a certain coefficient of friction, which increases the friction between the foot and the foundation, preventing slippage during use. Simultaneously, the bottom steel plate increases the contact area between the foot and the foundation, thereby distributing and evenly bearing the pressure on the foot, reducing the bearing pressure on the foundation, and minimizing foundation settlement and deformation.

Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a foundation reinforcement structure for a temporary support structure of a steel structure and its construction method. Background Technology

[0002] The scaffolding method involves using temporary supports and scaffolding as auxiliary structures during bridge construction to support and fix bridge components, ensuring the stability and safety of the entire bridge structure during construction. The scaffolding method can effectively solve the support problems of special structures such as suspension baskets, cantilever frames, and temporary support frames in bridge construction. This method can not only ensure that the bridge structure does not deform or shift during construction, but also ensure the safety of construction personnel and equipment.

[0003] Currently, a common practice when constructing temporary supports for steel structures is to place the base of the steel structure directly on the foundation, relying on the weight of the steel structure itself to stabilize the support structure. However, due to swaying and vibration caused by wind, earthquakes, or other external vibrations, the support structure is prone to unavoidable displacement, which can lead to uneven loads on the structural columns, resulting in structural cracks, collapses, and other safety hazards.

[0004] Therefore, we propose a foundation reinforcement structure for temporary steel structure supports and its construction method to address the problems mentioned above. Summary of the Invention

[0015] A method for using a foundation reinforcement structure for a temporary steel structure support includes the following steps:

[0016] S1. Drill holes in the foundation and fix the support components to the foundation using anchor bolts;

[0017] S2. Place the foot assembly on the wooden block and push and pull the slider to move the pressure plate to both sides of the first adjusting screw. Place a set of pressure plates on each base plate and fix the pressure plates to the surface of the base plate by tightening the nuts, so as to fix the foot assembly. Then, adjust the first adjusting nut in the foot assembly to approximately the same horizontal height, and then insert the starting rod into the first adjusting screw.

[0018] S3. Next, the first fastener at the end of the sweeping rod is locked to the first small hole on the first connecting plate through the first wedge-shaped pin, thereby completing the installation of the sweeping rod.

[0019] S4. Next, insert the upright pole vertically into the first connecting sleeve at the end of the starting pole. Then, lock the second fastener at the end of the horizontal pole to the second small hole on the second connecting plate through the second wedge pin, thereby completing the installation of the horizontal pole.

[0020] S5. Then, add a diagonal tie rod at the corresponding position, and lock the third fastener at the end of the diagonal tie rod to the second large hole on the second connecting plate through the third wedge pin.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. During use, the support components are fixed to the foundation by drilling holes and anchoring bolts, and then the pressure plate is fixed to the surface of the base plate by tightening nuts. This fixes the foot components to the surface of the wooden blocks, increasing the stability of the foot components. The wooden blocks have a certain coefficient of friction, which can increase the friction between the foot and the foundation and prevent the foot from slipping during use. At the same time, the bottom steel plate can increase the contact area between the foot and the foundation, thereby distributing and evenly bearing the pressure on the foot, reducing the bearing pressure of the foundation, and reducing foundation settlement and deformation.

[0024] 2. During use, the T-shaped blocks prevent the bottom of the pad from directly contacting the bottom steel plate and create multiple channels. This prevents rainwater and other fluids from accumulating inside and corroding the pad. At the same time, it also facilitates ventilation and keeps the pad dry, thereby improving the service life of the pad.

[0025] 3. During use, the wooden blocks can be installed in the steel structure using fixing bolts to prevent displacement of the wooden blocks, thereby improving the stability of the structure. Attached Figure Description

Finally, the distribution beams 11 are installed. The distribution beams 11 should be placed in the center of the top support 903 to avoid eccentric instability.

[0047] In this invention, firstly, foundation 1 must have sufficient bearing capacity. The surface of foundation 1 is treated with hardened concrete, and the treated area should extend at least 50cm beyond the scaffolding erection area. Uneven settlement is strictly controlled to meet design requirements. After foundation 1 is treated, the bearing capacity of the foundation is tested through foundation preloading. The preloading load should not be less than 1.2 times the sum of the self-weight of the superstructure borne by the foundation and the weight of the steel pipe support and formwork. The purpose of preloading is to test the bearing capacity of the foundation, eliminate the inelastic deformation of the foundation under construction loads, and prevent foundation 1 from settling, which could lead to cracking of the cast-in-place concrete structure. Only after the test is passed can the scaffolding be erected. During erection, a baseline is laid out according to the specific construction plan drawings, and the positioning is based on the baseline. Drill holes in foundation 1 and fix support assembly 2 to foundation 1 using anchor bolts 211. Then, place foot assembly 3 on wooden pad 203 and push and pull slider 206 to move pressure plate 208 to both sides of first adjusting screw 302. Place a set of pressure plates 208 on each base plate 301 and fix pressure plates 208 to the surface of base plate 301 by tightening nuts 209, thereby fixing foot assembly 3. Then, adjust the first adjusting nut 303 in foot assembly 3 to approximately the same horizontal height, and then insert starting rod 4 into first adjusting screw 302, ensuring that the length of insertion of starting rod 4 is not less than 15cm and the exposed length of first adjusting screw 302 is not more than 30cm. Connect the first connector 51 at the end of the sweeping rod 5 to the first small hole 43 on the first connecting plate 42 via the first wedge pin 54, and adjust the sweeping rod 5 to the same horizontal level. The center line of the sweeping rod 5 should not be more than 55cm from the base plate 301, thus completing the installation of the sweeping rod 5. Then, vertically insert the upright rod 8 into the first connecting sleeve 41 at the end of the starting rod 4. Next, connect the second connector 61 at the end of the horizontal rod 6 to the second small hole 83 on the second connecting plate 82 via the second wedge pin 64, thus completing the installation of the horizontal rod 6. Then, add the diagonal tie rod 7 at the corresponding position, and connect the third connector 72 at the end of the diagonal tie rod 7 to the second connecting plate 82 via the third wedge pin 75. The second large hole 84 on the 2 is locked to complete the installation of the diagonal brace 7. Next, the upper-level uprights 8, horizontal bars 6 and diagonal braces 7 are installed one after another. Then, the second adjusting screw 901 is inserted into the second connecting sleeve 81 on the top of each upright 8. The top support 903 is adjusted to the support height by the second adjusting nut 902. It is ensured that the length of the second adjusting screw 901 inserted into the second connecting sleeve 81 is not less than 15cm and the exposed length is not more than 40cm. At the same time, the cantilever length of the top support 903 extending out of the center line of the top horizontal bar 6 should not exceed 65cm, thus completing the installation of the top component 9. Finally, the distribution beam 11 is installed. The distribution beam 11 should be placed in the center of the top support 903 to avoid eccentric instability.

Place the foot assembly (3) on the pad (203) and push and pull the slider (206) to move the pressure plate (208) to both sides of the first adjusting screw (302). Place a set of pressure plates (208) on each base plate (301). Fix the pressure plate (208) to the surface of the base plate (301) by tightening the nut (209), thereby fixing the foot assembly (3). Then, adjust the first adjusting nut (303) in the foot assembly (3) to approximately the same horizontal height, and then insert the starting rod (4) into the first adjusting screw (302). S3. Then, the first fastener (51) at the end of the sweeping rod (5) is locked to the first small hole (43) on the first connecting plate (42) through the first wedge-shaped pin (54), thereby completing the installation of the sweeping rod. S4. Then, vertically insert the upright pole (8) into the first connecting sleeve (41) at the end of the starting pole (4). Next, lock the second fastener (61) at the end of the horizontal pole (6) to the second small hole (83) on the second connecting plate (82) through the second wedge pin (64) to complete the installation of the horizontal pole (6). S5. Then, add a diagonal tie rod (7) at the corresponding position and lock the third fastener (72) at the end of the diagonal tie rod (7) to the second large hole (84) on the second connecting plate (82) through the third wedge pin (75). S6. Then, insert the second adjusting screw (901) into the second connecting sleeve (81) on the top of each pole (8), and adjust the top support (903) to the support height by means of the second adjusting nut (902), thereby completing the installation of the top component (9). Finally, install the distribution beam (11). The distribution beam (11) should be placed in the center of the top support (903) to avoid eccentric instability.
