Description

Technical Field

[0001] This utility model relates to the field of construction equipment for building engineering, specifically a wall tie for external scaffolding in residential building engineering. Background Technology

[0002] In the complex system of residential building construction, external scaffolding acts like a sturdy network around the building, a crucial support for ensuring the safety and efficiency of construction workers performing high-altitude operations. From foundation construction to the main structure and then to the decoration and finishing stages, external scaffolding consistently provides a stable working platform for construction workers, bearing the weight of workers, building materials, and various construction tools. It also effectively protects the construction area from falling objects and causing accidents. Wall ties, as the core link connecting the external scaffolding to the main building structure, act like the scaffolding's "anchor points." They tightly connect the scaffolding to the building, effectively limiting the deformation and displacement of the scaffolding under external forces such as wind loads and construction loads by transferring horizontal and vertical loads, ensuring the stability and reliability of the overall scaffolding structure. It can be said that the performance and quality of wall ties directly affect the safety performance of the entire external scaffolding system, thus impacting the construction safety and progress of the residential building project.

[0003] Currently, wall tie technology used in residential building construction faces several challenges in practical applications. When dealing with diverse gaps between scaffolding and the building, traditional wall ties, due to the limitations of their length adjustment mechanisms, struggle to accurately adapt to various complex construction scenarios. Different residential buildings differ in design style, structural form, and construction techniques, resulting in varying distances between scaffolding installations and building walls. Traditional wall ties are typically designed to standard lengths; when the gap exceeds their applicable range, installation becomes difficult. Even if installed, they cannot consistently provide stable support to the scaffolding throughout the entire construction period. Meanwhile, in terms of connection with scaffolding straight poles, given that the diameter specifications of scaffolding straight poles are not completely uniform, the connection structure of traditional wall ties lacks flexibility. In actual operation, construction workers often need to spend extra time and effort to modify or adjust the wall ties in order to connect them with straight poles of different diameters.

[0007] Specifically, a frustum column is installed on the outer side of the threaded tube and between the connecting plate and the extension rod via a threaded fit. Positioning rods are arranged in an array on the side wall of the connecting plate facing the threaded tube. An inclined rod is fixedly installed at the end of the positioning rod. An insertion hole is opened in the center of the inclined rod. A movable rod is inserted into the insertion hole.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0017] See Figure 1-4 The present invention relates to a wall tie component for external scaffolding in residential building construction, comprising a wall tie plate 1, a threaded pipe 2, an extension rod 3, a T-shaped rod 4, and a support block 6. The wall tie plate 1 has a quadrilateral cross section, and mounting holes 10 are arranged in a rectangular pattern inside the wall tie plate 1. The wall tie plate 1, as a direct contact component with the wall, directly covers the outside of the wall during installation. Before installing the wall tie plate 1, the wall should be drilled to create an assembly groove. When fixing the wall tie plate 1, simply pass the expansion bolts through the mounting holes 10 and fix them in the assembly groove to complete the fixing and installation of the wall tie plate 1. One end of the threaded pipe 2 is welded to the center of the side wall of the wall connecting plate 1. The threaded pipe 2 and the wall connecting plate 1 are an integral part, and the threaded pipe 2 itself is a component made of high-strength steel, which ensures that it is not easily deformed during use. The extension rod 3 has a threaded groove at the center of one end. The extension rod 3 is installed on the threaded tube 2 through the threaded groove. The extension rod 3 can be rotated on the outside of the threaded tube 2 to adjust the combined length of the two. One end of the T-shaped rod 4 is concentrically welded to the end face of the extension rod 3. A sleeve 5 is rotatably installed on the outer surface of the T-shaped rod 4. The sleeve 5 can rotate along the outer wall of the T-shaped rod 4. Support arms 51 are symmetrically welded to the outer wall of the sleeve 5. Support arms 51 are inclined to the horizontal plane at any position, and the inclination angles are equal, that is, the end faces of the two support arms 51 are flush in the vertical direction. The support block 6 is fixedly installed at the end of the support arm 51. A first through hole 61 is symmetrically formed along its longitudinal direction inside the support block 6, and a second through hole 62 is formed along its transverse direction inside the support block 6. Figures 2-5As shown, the first through hole 61 and the second through hole 62 are interconnected. A displacement block 63 is inserted into the first through hole 61. The displacement block 63 can move laterally along the first through hole 61. The difference between the thickness of the first through hole 61 and the thickness of the displacement block 63 is the maximum displacement of the displacement block 63. A support rod 64 is symmetrically welded to the side wall of the displacement block 63 facing the second through hole 62. A support frame 65 is welded to the end of the support rod 64, and clamping rods 66 are symmetrically installed on the support frame 65. Figure 1 As shown, the number of clamping rods 66 on a single support frame 65 is set to two, and the horizontal gap between the two clamping rods 66 on each of the two support frames 65 is the combination area; Cover plates 67 are symmetrically installed on both sides of the support block 6. The two ends of the cover plates 67 are in contact with but not connected to the outer wall of the support rod 64. A compression spring 68 is fixedly installed between the cover plates 67 and the opposite side of the displacement block 63. The compression spring 68 can push the displacement block 63 to press against its inner wall on the inner side of the first through hole 61. In this state, the above-mentioned combined area is at its minimum value. In specific operation, the overall length of this utility model (the overall length is the horizontal distance between one side wall of the wall connecting plate 1 and the outer wall of the clamp rod 66) is controlled by adjusting the combined length between the extension rod 3 and the threaded pipe 2, so that the overall length is less than the gap between the scaffold and the wall. After the adjustment is completed, the wall connecting plate 1 is fixed to the wall and the center line of the combined area is aligned with the center of the scaffold straight rod. Then, the construction workers rotate the extension rod 3 to move the combined area toward the scaffold straight rod. When the clamp rod 66 contacts the scaffold straight rod, it will slide along its outer wall. The displacement block 63 moves along the first through hole 61 under the action of the compression force. The cover plate 67 compresses the compression spring 68. When the clamp rod 66 is displaced to Figure 1 After reaching the specified position, the rebound force generated when the compression spring 68 is compressed pushes the clamping rod 66 to press against the outer wall of the scaffold straight rod again. The outer wall of the support rod 64 is welded with a side arm 641, and a locking hole 640 is opened in the side arm 641. A locking bolt 642 is installed between the locking holes 640 of the two side arms 641 on the same horizontal plane. A locking nut 643 is installed at the tail of the locking bolt 642. When the clamping rod 66 moves accurately to the desired position... Figure 1 After positioning, insert the locking bolt 642 into the locking hole 640, and install the locking nut 643 on the locking bolt 642 to complete the installation and fixing of this utility model. This method can be applied to the scaffolding fixing requirements with different gaps from the wall, and can also be adapted to scaffolding straight poles with different outer diameters. It should be noted that when installing this utility model, the clamping rod 66 can be fixed on the scaffolding straight rod first, and then the wall connecting plate 1 can be driven to fit against one side of the wall by rotating the threaded pipe 2. Then the drill bit of the drilling equipment can be inserted into the mounting hole 10 to drill out the above-mentioned assembly groove, and then it can be fixed by expansion bolts. Meanwhile, the overall length mentioned above should not exceed the maximum gap between the scaffolding and the wall during the construction process.

[0018] A ball bearing is embedded at the connection between the T-shaped rod 4 and the sleeve 5, and the outer side of the ball bearing is coated with lubricating grease. During the rotation of the sleeve 5, the friction between its inner wall and the outer wall of the T-shaped rod 4 is reduced, thereby reducing the wear between the two.

[0019] In another embodiment, see Figure 1 and Figure 6 A frustum column 7 is installed on the outside of the threaded pipe 2 and between the wall connecting plate 1 and the extension rod 3 through a threaded engagement. The outer cross-section of one end face of the frustum column 7 is hexagonal, which facilitates the use of a wrench to rotate the frustum column 7 along the threaded pipe 2. Positioning rods 11 are arranged in an array on the side wall of the wall-connecting plate 1 facing the threaded pipe 2. An inclined rod 12 is fixedly installed at the end of the positioning rod 11. An insertion hole 121 is opened in the center of the inclined rod 12. A movable rod 13 is inserted into the insertion hole 121. One end of the movable rod 13 contacts the outer side of the frustum column 7. The other end of the movable rod 13 is welded with an abutment rod 14. In actual operation, the frustum column 7 can be moved toward the wall-connecting plate 1 by a wrench. The outer ring of the frustum column 7 will squeeze one end of the movable rod 13 and push it to move along the insertion hole 121 until the outer wall of the abutment rod 14 is close to the wall. This method provides multi-point support and increases the stability of the connection with the wall. Meanwhile, the outer ring of the abutment rod 14 is provided with anti-slip textures 141 at equal angles along its circumference to increase the friction between the abutment rod 14 and the outer side of the wall.

[0020] The cross-section of the insertion hole 121 is rectangular, and the movable rod 13 is formed by coaxial welding of a rectangular rod and a circular rod. The rectangular rod area is inserted into the insertion hole 121. In this state, the movable rod 13 does not rotate relative to the wall during its movement along the insertion hole 121, ensuring that the contact rod 14 is in parallel contact with the wall on one side of the wall along the wall connecting plate 1.

[0021] like Figure 6 As shown, the tilting rod 12 is a ferromagnetic metal component. A disk 131 is provided at the connection between the rectangular rod and the circular rod. Under normal conditions, the magnetic attraction of the disk 131 attracts the movable rod 13 to one side of the tilting rod 12, ensuring that it will not fall off during installation.

[0022] For further details, please refer to [link / reference]. Figure 6 A steel ball 132 is embedded at one end of the movable rod 13 facing the truncated column 7. The outer surface of the steel ball 132 is smooth. When the truncated column 7 is rotated, its outer ring directly contacts the steel ball 132, avoiding wear on the outer ring of the movable truncated column 7 due to sharp corner contact.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
