Description
Technical Field
[0001] This utility model relates to the field of construction equipment, and in particular to a wall-connecting structure and its corresponding scaffolding structure. Background Technology
[0002] Wall ties, as an important component of scaffolding, are used to connect the scaffold frame to the main structure of the building. They are components that can transmit tensile and compressive forces, enhance the overall stability of the scaffolding, and prevent major accidents such as scaffolding tilting or collapse. Currently, common methods for connecting the scaffold frame to the main structure of the building include the pre-embedded steel pipe method, the post-anchoring method, the bracing method, the hoop method, and the pre-embedded iron plate method. Each of these methods has certain drawbacks. For example, the pre-embedded steel pipe method is costly, difficult to dismantle, and there is a risk of water seepage at the openings later. The use of open flames during dismantling poses a fire hazard. The post-anchoring method involves difficult drilling, the expansion bolts have low load-bearing capacity and are prone to loosening, the use of chemical bolts makes hole cleaning difficult, the construction requirements are high, the cost is high, and the use of open flames during dismantling poses a fire hazard.
[0003] Therefore, it is necessary to provide a wall-connecting structure and its corresponding scaffolding structure to solve the above problems. Utility Model Content

The wall-connecting structure fixes the embedded part to the template by placing one end of a pre-embedded screw rod inside a pre-embedded component, and the other end of the pre-embedded screw rod passing through a template and threadedly connected to a fixing nut. After concrete is poured and the template is removed, the pre-embedded screw rod is taken out and one end of the wall-connecting screw rod is fixed inside the pre-embedded component. Wall-connecting fasteners are used to fix the wall-connecting steel pipe. Wall-connecting screw rods are used to fix the wall-connecting fasteners to the pre-embedded component, thereby fixing the wall-connecting steel pipe to the wall, facilitating installation and disassembly, and improving assembly efficiency.

[0029] Please refer to Figure 1 , Figure 2In this embodiment, the wall-connecting structure 10 includes an embedded part 12, an embedded screw 13, a wall-connecting fastener 14, and a wall-connecting screw 15. The embedded part 12 is hollow inside and open at one end, with the open end of the embedded part 12 tightly against the inner surface of the template. One end of the embedded screw 13 is located inside the embedded part 12, and the other end of the embedded screw 13 passes through the template and is threaded to a fixing nut 16, thus fixing the embedded part 12 to the template. After pouring concrete and removing the template, the embedded screw 13 separates from the embedded part 12. The embedded screw 13 can be directly inserted into the embedded part 12, or it can be threaded into the embedded part 12, facilitating removal after demolding. The wall-connecting fastener 14 is used to fix the wall-connecting steel pipe 32. The wall tie rod 15 is used to fix the wall tie fastener 14 to the embedded part 12, thereby fixing the wall tie steel pipe 32 to the wall 20. This facilitates installation and disassembly, improving assembly efficiency. The embedded part 12, embedded tie rod 13, and wall tie rod 15 have simple structures and can be repeatedly recycled, significantly saving costs.
[0030] In this embodiment, please refer to Figure 2 One end of the wall tie rod 15 passes through one end of the wall tie fastener 14 and the opening of the embedded part 12, and is connected to the internal thread of the embedded part 12.

The wall tie structure 10 fastener can rotate 360 degrees along the wall tie rod 15, facilitating the positioning and adjustment of the wall tie steel pipe 32.
[0038] Embedded part 12 is embedded in reinforced concrete, offering good rigidity, accurate placement, and ease of operation. Since embedded part 12 is located on the side of the beam (wall), scaffolding modifications are unnecessary, reducing safety hazards caused by delayed repairs. Furthermore, dismantling is convenient, requiring no welding or cutting, reducing fire hazards, and eliminating the need for patching holes, thus minimizing water seepage risks. Except for embedded part 12 and embedded nut 11, all other components of this wall tie structure 10 are recyclable, saving costs.

The uprights 31 and the corresponding wall-connecting steel pipes 32 are fixedly connected by right-angle couplers 33, making installation and dismantling convenient.
[0040] The wall tie structure 10 first embeds and fixes the pre-embedded parts 12 onto the side formwork of the beam (wall). When the side formwork is removed, the fixing nuts 16 are unscrewed. When the concrete strength of the beam (wall) reaches 15MPa or more, the pre-embedded screws 13 on the pre-embedded parts 12 are removed. The wall tie screws 15 are inserted into the wall tie fasteners 14 and then screwed into the pre-embedded parts 12. The wall tie steel pipe 32 is fastened through the wall tie fasteners 14 and pressed against the beam (wall). Finally, the wall tie steel pipe 32 is connected to the uprights 31 of the scaffolding with right-angle fasteners 33 to form a whole.

[0044] 2. Provide construction plan briefings to construction teams and personnel to ensure that operators understand the relevant construction techniques and requirements of the new wall-connecting structure 10.
[0045] 3. Prepare an on-site delivery plan for the required specifications and quantities of 10 wall tie structures according to the scaffolding scheme requirements, and verify the factory inspection reports, product certificates, appearance, quantity, etc. of the delivered materials in accordance with the construction scheme and specifications.
[0046] II. Beam (Wall) Formwork Installation
[0047] Install the formwork for the structural beams (walls) of the building according to the construction drawings and construction plan requirements.
[0048] 1. Before installing the template, apply a release agent to the template and keep the template clean and tidy.
[0049] 2. The template installation requires a flat surface, tight joints, overall reliability, and accurate internal and external corner axes. In order to ensure that the template does not leak concrete, sponge paper is used to stick the joints to prevent leakage.
[0050] III. Measurement and Positioning
[0051] 1. After the beam (wall) formwork is reinforced, determine the distribution position of the wall tie structure 10 on the floor according to the specifications and the requirements for the arrangement of the wall tie structure 10 in the special construction plan for scaffolding, and mark the points on the uprights 31 inside the scaffolding with a bright colored paint pen.
[0052] 2. Prepare a 1.0m PVC pipe in advance. Determine the position according to the wall tie structure 10. Place the PVC pipe close to the main node of the scaffold upright 31 and no more than 300mm away, and make a mark perpendicular to the beam (wall) formwork. Mark the point on the formwork with a bright colored paint pen.
[0053] IV. Installation of Embedded Parts 12
[0054] 1. Drill 12mm holes at the marked positions on the side formwork of the beam (wall), and then install the wall connection structure 10 embedded parts 12 at the hole positions. The embedded parts 12 should be installed firmly and in accurate positions.
[0055] 2. The position of the pre-embedded part 12 in the wall tie structure 10 must be 10cm below the concrete structure surface.
[0056] 3. When installing the embedded part 12, the holes of the side template should be cleaned thoroughly.
[0057] 4. When tightening the fixing nut 16, the torque should not be too high to avoid damaging the threads.
[0058] V. Concrete Pouring of Beams (Walls)
[0059] After the beam (wall) reinforcement and formwork have passed inspection, concrete pouring can proceed.
[0060] 1. For the concrete pouring of beams (walls), pour the concrete continuously in layers from one end to the other or from the middle to both ends in one continuous pouring.
[0061] 2. When pouring concrete, the embedded part 12 should be protected. The vibrator should not be used to vibrate the embedded part 12 to avoid damage or displacement of the embedded part 12.
[0062] VI. Removal of Beam (Wall) Side Formwork
[0063] 1. Once the concrete has reached a strength sufficient to prevent damage to its surface and edges from the removal of the side formwork, it can be removed. The removed side formwork should be transported away promptly, categorized, and hoisted to designated locations for stacking, and retrieved as needed.
[0064] 2. Before removing the side mold, first unscrew the pre-embedded fixing nut 16 to prevent collision with the pre-embedded screw 13 when removing the side mold.
[0065] VII. Scaffolding connection construction
[0066] When the concrete strength reaches 15MPa or above, the wall tie rod 15 can be installed. First, take out the embedded threaded rod 13 on the embedded part 12, then insert the metal wall tie rod 15 into the wall tie fastener 14 and the embedded part 12 and tighten it with the embedded nut 11. Fasten the wall tie steel pipe 32 through the wall tie fastener 14 and press it against the beam (wall). Finally, connect and lock the wall tie steel pipe 32 and the main node of the scaffold upright 31 through the right angle fastener 33.
[0067] 8. Inspection and Acceptance of Wall Tie Structure
[0068] 1. Check whether the quantity and construction method of the wall ties are consistent with the plan.
[0069] 2. Check whether the wall tie rods are firmly against the beam (wall).
[0070] 3. Check whether the wall ties and scaffold uprights 31 are secure.
[0071] 9. Demolition and Recycling of Wall Tie-in Structures
[0072] 1. The wall ties 10 must be dismantled layer by layer along with the scaffolding. Before dismantling, a safety inspection of the scaffolding must be carried out to confirm that there are no safety hazards before dismantling can proceed; the dismantling order is from top to bottom, with the most recently erected structures being dismantled first and the most recently erected structures being dismantled last.
[0073] 2. During dismantling, operators must wear safety belts, soft-soled non-slip shoes, and leg wraps.
[0074] 3. After the dismantled wall tie structure components and other materials are transported to the ground, they should be cleaned, inspected, repaired and maintained in a timely manner, and stored in a classified and stacked manner according to type and specification for future use.
