Description
Technical Field
[0001] This utility model belongs to the technical field of double-channel steel formwork support beams for underground garages, and particularly relates to a limiting structure for the installation of double-channel steel formwork support beams for underground garages. Background Technology
[0002] The main function of double-channel steel formwork support beams in the construction of underground parking garages and other buildings is to provide stable support. During the construction of concrete structures such as the roof slab and beams of the underground parking garage, formwork needs to be set up to form the cavity for concrete pouring. Double-channel steel formwork support beams can effectively support these formworks, bear the weight of the formwork and the subsequent poured concrete, prevent the formwork from sinking or deforming during construction, and ensure that the concrete structure can be formed according to design specifications. Secondly, it helps to distribute the load evenly. During the concrete pouring process, the weight is not evenly applied to the formwork. Double-channel steel formwork support beams can transfer these uneven loads more evenly to the supporting structure below (such as scaffolding, columns, etc.), avoiding excessive local stress that could lead to local instability or damage to the support system, thereby ensuring the safety and stability of the entire construction support system.
[0003] The currently used double-channel steel formwork support beams present certain problems during installation. The main issue is that it is difficult for workers to flexibly adjust the support structure according to specific site conditions. Typically, detailed measurements and customized beam height installation are required before installation. This process is not only time-consuming but also increases operational complexity, thus affecting the convenience of on-site installation. Utility Model Content

[0031] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0032] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] Please see Figures 1 to 6 This utility model provides a limiting structure for installing a double-channel steel formwork support beam in an underground garage, including a base 1. Each of the four corners of the base 1 is connected to a first bolt 2 via a threaded connection. A first support 3 is installed on the upper side of the base 1. A first slide rail 4 is provided inside the first support 3, and a load-bearing drive component is slidably connected within the first slide rail 4. A load-bearing seat 5 is installed at the top of the load-bearing drive component. A beam 6 is installed inside the load-bearing seat 5, and a limiting component that contacts the beam 6 is installed on the load-bearing seat 5.
[0034] The above-mentioned solution is as follows: During the installation of beam 6, the first bolt 2 is first tightened so that one end of the first bolt 2 contacts the ground. Then, beam 6 is placed in the bearing seat 5, and the limiting component is used to fix beam 6 to prevent it from slipping during movement. Next, the bearing drive component moves upward in the first slide rail 4, and the bearing seat 5 and beam 6 rise synchronously to the preset position. The rising height of beam 6 is adjusted according to the site requirements. After reaching the specified height, the limiting component moves in the opposite direction to release beam 6. The staff then remove beam 6 from the bearing seat 5 and place it on the support column to complete the installation. The use of the limiting component ensures the stability of beam 6 during the lifting process and effectively prevents slippage, thereby improving the safety and reliability of the entire installation process.
[0035] It should be noted that two sets of load-bearing drive components can be used together to drive the beam 6 to rise.
[0036] Furthermore, the load-bearing drive component includes a first slider 7 slidably sleeved in the first slide rail 4, and a reciprocating screw 8 is rotatably connected in the first slide rail 4; the top end of the reciprocating screw 8 is rotatably connected to the top wall of the first slide rail 4; the first slider 7 is threadedly connected to the reciprocating screw 8.
[0037] Furthermore, a first motor 9 is installed on the bottom wall of the first slide rail 4; the output end of the first motor 9 is connected to the bottom end of the reciprocating screw 8, and a first support frame 10 is installed on the upper side of the first slider 7; the top of the first support frame 10 passes through the first slide rail 4; the top of the first support frame 10 is fixedly connected to the lower side of the bearing seat 5.
[0038] Furthermore, the two sides of the first slider 7 are attached to the outer wall of the first support base 3, and the first slider 7 is I-shaped.
[0039] Using the above scheme: In use, the output end of the first motor 9 rotates, which drives the reciprocating screw 8 connected to it to rotate synchronously. Since the first slider 7 is connected to the reciprocating screw 8 by a thread, when the reciprocating screw 8 rotates, it pushes the first slider 7 to move upward along the first slide rail 4. As the first slider 7 moves, it will drive the first support frame 10 and the bearing seat 5 on it to move synchronously. When the bearing seat 5 moves to the preset position, the first motor 9 stops rotating. At this time, the beam 6 can be taken out and placed on the support column.
[0040] Furthermore, the limiting component includes a second slide rail 11 formed on the support seat 5; two symmetrical second sliders 12 are slidably connected in the second slide rail 11; and a first threaded hole is formed in the second slider 12.
[0041] Furthermore, a second bolt 14 is threadedly connected to the first threaded hole, and one end of the second bolt 14 is attached to the side wall of the beam 6; the second slider 12 is provided with first fixing holes 15 on both sides of the second bolt 14; the bearing seat 5 is provided with a plurality of second fixing holes 16 aligned with the first fixing holes 15.
[0042] Furthermore, a fixing rod 17 is installed in the first fixing hole 15, and the other end of the fixing rod 17 extends into the second fixing hole 16.
[0043] Using the above scheme: When the beam 6 is placed on the bearing seat 5, the two second sliders 12 are moved relative to each other in the second slide rail 11 by moving them. After the second sliders 12 move to the preset position, the fixing rod 17 is inserted into the first fixing hole 15 and the second fixing hole 16 to fix the position of the second sliders 12. Then, the second bolt 14 is screwed into the first threaded hole and rotated continuously until the second bolt 14 moves to the preset position. When the end of the second bolt 14 contacts the beam 6, the second bolt 14 will apply pressure to the beam 6, thereby playing a limiting role and preventing the beam 6 from slipping during the rising process.
[0044] It should be noted that since the second bolts 14 are provided on both sides of the bearing seat 5, the side walls of both sides of the beam 6 can be simultaneously limited.
[0045] The working principle of this utility model:
[0046] During the installation of beam 6, firstly, the first bolt 2 is tightened so that one end of the first bolt 2 contacts the ground. Then, beam 6 is placed in the bearing seat 5. After beam 6 is placed on the bearing seat 5, the two second sliders 12 are moved relative to each other in the second slide rail 11 by actuation. After the second sliders 12 move to the preset position, the fixing rod 17 is inserted into the first fixing hole 15 and the second fixing hole 16 to fix the position of the second sliders 12. Next, the second bolt 14 is screwed into the first threaded hole and continuously rotated until the second bolt 14 moves to the preset position. When the end of the second bolt 14 contacts beam 6, the second bolt 14 will... Pressure is applied to the beam 6 to limit its movement and prevent it from slipping during ascent. Then, the output of the first motor 9 rotates, which drives the reciprocating screw 8 connected to it to rotate synchronously. Since the first slider 7 is connected to the reciprocating screw 8 by a thread, when the reciprocating screw 8 rotates, it pushes the first slider 7 to move upward along the first slide rail 4. As the first slider 7 moves, it drives the first support frame 10 and the bearing seat 5 on it to move synchronously. When the bearing seat 5 moves to the preset position, the first motor 9 stops rotating. At this time, the beam 6 can be removed and placed on the support column, completing the installation of the beam 6.
