Abstract
Description
Technical Field
[0001] This utility model relates to the field of external scaffolding fixing, specifically a tie-joint fixing device for external scaffolding. Background Technology
[0002] In existing building construction, external scaffolding needs to be set up on the outside of the walls to support construction workers or materials. To ensure the stability of the external scaffolding, tie rods are usually installed between the scaffolding and the building walls to prevent the scaffolding from overturning. The external scaffolding is generally fixed to the wall by tie rods or column clamps. However, when the external scaffolding is being constructed on the ground floor, because the bottom of the building is a basement structure, some areas in the basement do not have door or window openings. Therefore, tie rods cannot be effectively used for tie rods or column clamps. Furthermore, the basement floor height is usually high. Without tie rods at excessive heights, the overall stability of the external scaffolding structure cannot be guaranteed, resulting in certain safety hazards. Utility Model Content
[0003] The purpose of this utility model is to provide a tie rod fixing device for external scaffolding, which can solve the technical problem that the lack of tie rods in the basement affects the stability of the external scaffolding. By setting fixing rods on the wall or support piles, the two ends of the tie rods are fixed and limited, thereby improving the stability of the tie rods and providing stable support for the external scaffolding.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A tie rod fixing device for external scaffolding includes a tie rod disposed between a wall and supporting piles. External scaffolding is provided between the wall and supporting piles, and the tie rod is connected to the external scaffolding. Both ends of the tie rod are provided with fixing seats, and the two fixing seats are respectively connected to the wall and the supporting piles. Fixing rods are symmetrically provided on both the wall and the supporting piles. The bottom of the fixing rod is provided with a base. The fixing rod is provided with multiple mounting seats for use with the wall or supporting piles. Limiting rings are symmetrically provided on both sides of the fixing seats. The limiting rings are sleeved on the outside of the fixing rod. The tie rod is provided with a length adjustment component.
[0006] Furthermore, the mounting base includes a mounting plate and a fixing ring. The mounting plate is symmetrically provided with bolt holes for use with the wall or support piles, and the fixing ring is sleeved on the outside of the fixing rod.
[0007] Furthermore, the fixed base is provided with connecting plates symmetrically on both sides, and the limiting ring is fixed on the connecting plate, with the limiting ring located above the fixed ring.
[0008] Furthermore, the length adjustment component includes a sleeve, and the two wall-pulling rods are symmetrically arranged, with the two wall-pulling rods slidably connected to both ends of the sleeve.
[0009] Furthermore, the wall-pulling rod is threadedly connected to the rod sleeve.
[0010] Furthermore, both the fixing seat and the base are provided with multiple anchor bolt holes.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. The structure of this utility model has fixed seats at both ends of the wall tie rod, which are connected to the wall and the support pile respectively. At the same time, a length adjustment component is set on the wall tie rod, so that the length of the wall tie rod can be fully adapted to the distance between the wall and the support pile, thereby making the wall tie rod firmly fixed between the wall and the support pile, providing effective tie support for the external scaffolding, improving the adaptability to different buildings, and ensuring the stability of the external scaffolding structure;
[0013] 2. The wall and support piles are symmetrically equipped with fixing rods. Each fixing rod has a base at its bottom and multiple mounting seats on it for use with the wall or support piles. Each mounting seat has symmetrical limiting rings on both sides, which are fitted over the fixing rod. In this structure, when the fixing seats at both ends of the wall tie rod are fixed to the wall or support pile, the fixing rod is first fixed to the ground using the base. Then, the mounting seats are used to fix the fixing rod to the wall or support pile. Next, the limiting rings on both sides of the fixing seat are fitted over the fixing rod. The fixing seat is then slid down to the designated position and finally fixed to the wall or support pile. This structure uses the fixing rod to limit and reinforce the fixing seat, making it difficult for it to separate from the wall or support pile, thus greatly improving the stability of the wall tie rod structure and further enhancing the traction and fixing effect of the external scaffolding.

[0021] Reference Figure 1 and Figure 2This utility model describes a tie rod fixing device for external scaffolding. The main structure includes a tie rod 3 installed between a wall 1 and supporting piles 2. The tie rod 3 is horizontally installed on the wall 1 and the supporting piles 2 on one side of the wall 1. External scaffolding 4 is installed between the wall 1 and the supporting piles 2, providing support and protection for workers near the edge. The tie rod 3 is connected to the external scaffolding 4, typically through its main nodes, to improve the stability of the external scaffolding 4 and prevent it from overturning. Both ends of the tie rod 3 are open... The wall tie rod 3 is fixed with a fixed base 5 by welding or integral molding. The two fixed bases 5 are respectively connected to the wall 1 and the support pile 2 by anchor bolts or welding. This structure fixes the wall tie rod 3 between the wall 1 and the support pile 2, improving the stability of the wall tie rod 3 and ensuring the tie and fixation effect of the external scaffolding 4. Fixed rods 6 are symmetrically provided on the wall 1 and the support pile 2. The fixed rods 6 extend vertically. The bottom of the fixed rod 6 is fixed with a base 7 by welding or integral molding. The base 7 is fixed to the ground by anchor bolts, etc. The fixed rod 6 is provided with multiple mounting seats for use with the wall 1 or the support pile 2. After the bottom of the fixing rod 6 is fixed to the ground by the base 7, it is then fixed to the wall 1 or the support pile 2 by multiple mounting seats. This ensures that the fixing rod 6 will not tilt or shake vertically or horizontally, guaranteeing the structural stability of the fixing rod 6. The two sides of the fixing seat 5 are symmetrically fixed with limit rings 8 by welding or bolts. The limit rings 8 are sleeved on the outside of the fixing rod 6. Before the fixing seat 5 is fixed to the wall 1 or the support pile 2, the limit rings 8 on both sides of the fixing seat 5 are sleeved on the fixing rod 6 on both sides, and then moved downwards along the fixing rod 6 to the designated position. Afterwards, the fixing seat... 5. After installation, the fixing seat 5 is firmly fixed to the wall 1 or support pile 2 through the cooperation of the limiting rings 8 on both sides and the fixing rod 6, which makes it less likely to fall off. This further ensures the firmness of the connection between the fixing seat 5 and the wall 1 or support pile 2, thereby improving the firmness of the tie rod 3 structure. The tie rod 3 is equipped with a length adjustment component, which can adjust the length of the tie rod 3 to adapt to the distance between the wall 1 and support pile 2 of different buildings, thereby meeting the tie requirements of the external scaffolding 4 for different types of buildings and improving the adaptability of the tie fixing of the external scaffolding 4.
[0022] Preferred, refer to Figure 4The mounting base includes a welded or integrally formed fixed mounting plate 9 and a fixing ring 10, which together form an Ω shape. The mounting plate 9 is symmetrically provided with bolt holes 11 for use with the wall 1 or the support pile 2. After the bolts pass through the bolt holes 11, the mounting plate 9 is fixed to the wall 1 or the support pile 2. The fixing ring 10 is sleeved on the outside of the fixing rod 6. This structure allows the fixing rod 6 to maintain a constant distance from the wall 1 or the support pile 2 in the lateral direction through the fixing ring 10, while the bottom is fixed to the ground through the fixing seat 5, making the installation operation of the fixing rod 6 more efficient and stable.
[0023] Preferred, refer to Figure 3 The fixed base 5 has symmetrical connecting plates 12 fixed on both sides by welding or integral molding. The thickness of the connecting plates 12 is adapted to the mounting plate 9. The limiting ring 8 is fixed on the connecting plate 12 by welding or integral molding. The limiting ring 8 is located above the fixed ring 10. This structure uses the connecting plate 12 to connect and support the limiting ring 8 and to fill the gap between the limiting ring 8 and the wall 1, so that the limiting ring 8 can be accurately fitted on the fixing rods 6 on both sides, making the cooperation between the fixed base 5 and the fixing rods 6 more convenient and accurate.
[0024] Preferably, the length adjustment component includes a sleeve 13, and two wall-pulling rods 3 are symmetrically arranged. The two wall-pulling rods 3 are slidably connected to the two ends of the sleeve 13. With this structure, the sum of the lengths of the wall-pulling rods 3 and the sleeve 13 can be changed by sliding the wall-pulling rods 3 relative to the sleeve 13, thereby fully adapting to the distance between the wall 1 and the support pile 2. The structure is simple and the length adjustment is more efficient and convenient.
[0025] Preferably, the wall-pulling rod 3 is threadedly connected to the rod sleeve 13. This structure allows the rod sleeve 13 to be moved relative to the wall-pulling rod 3 simply by rotating it, thereby adjusting the sum of the lengths of the rod sleeve 13 and the wall-pulling rod 3. The threaded connection automatically limits the adjusted length, further simplifying the length adjustment steps and improving the overall structural robustness of the wall-pulling rod 3 after length adjustment.
[0026] Preferably, both the fixing seat 5 and the base 7 are provided with multiple anchor bolt holes 14. The fixing seat 5 and the base 7 are fixed by passing the anchor bolts through the anchor bolt holes 14, making the fixing operation of the two more secure and convenient.
[0027] Working Principle: The structure of this utility model features fixed seats 5 at both ends of the wall tie rod 3. These fixed seats 5 are connected to the wall 1 and the support pile 2 respectively. A length adjustment component is also provided on the wall tie rod 3, allowing its length to be fully adapted to the distance between the wall 1 and the support pile 2. This ensures the wall tie rod 3 is firmly fixed between the wall 1 and the support pile 2, providing effective tie support for the external scaffold 4, improving adaptability to different buildings, and ensuring the structural stability of the external scaffold 4. Fixed rods 6 are symmetrically arranged on both the wall 1 and the support pile 2. Each fixed rod 6 has a base 7 at its bottom and multiple mounting seats for use with the wall 1 or the support pile 2. The fixed seats 5 are symmetrically arranged on both sides. With limiting rings 8 fitted around the outside of the fixing rod 6, when the fixing seats 5 at both ends of the wall tie rod 3 are fixed to the wall 1 or the support pile 2, the fixing rod 6 is first fixed to the ground by the base 7 at the bottom, and then the fixing rod 6 is fixed to the wall 1 or the support pile 2 by the mounting seat. After that, the limiting rings 8 on both sides of the fixing seat 5 are fitted around the outside of the fixing rod 6, and then the fixing seat 5 is slid down to the designated position and then fixed to the wall 1 or the support pile 2. This structure uses the fixing rod 6 to limit and reinforce the fixing seat 5, making it difficult for it to separate from the wall 1 or the support pile 2, thereby greatly improving the structural strength of the wall tie rod 3 and further improving the tie-fixing effect of the external scaffolding 4.
