Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a rear-mounted, angle-adjustable wall tie and scaffolding that improves the appearance of exterior wall repairs. Background Technology

[0002] In the current field of urban old residential area renovation and reconstruction, ground-supported scaffolding is widely used as a working platform and protective measure for exterior wall repairs. Wall ties, as safety components of ground-supported scaffolding, are key components for the safety and stability of the scaffolding. Their installation on the exterior wall and connection to the scaffolding plays a crucial role in the aesthetics of the repaired exterior. Therefore, the safety, convenience, flexibility, and practicality of wall ties during installation and dismantling are particularly important. However, traditional post-installed wall ties have several problems, mainly in the following aspects: Traditional wall ties are heavy and bulky. The installation process involves hoisting, transporting, and manual assembly with fasteners, which not only increases transportation costs but also affects the efficiency of scaffolding construction. Secondly, the embedded plate of the wall tie is large, making it impossible to work on this part during exterior wall repairs; repairs can only be done after dismantling, easily affecting the aesthetics of the exterior wall repair. Furthermore, the traditional wall tie embedded plate installation uses four-corner opening expansion bolts for connection, which significantly impacts the convenience of construction. This method also consumes a large number of expansion bolts and is inefficient. Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, this utility model provides a rear-mounted, angle-adjustable wall tie and scaffolding that improves the appearance of exterior wall repairs.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a rear-mounted, angle-adjustable wall-connecting component that improves the appearance of exterior wall repairs, including an embedded part, a first screw, a first through bolt, a sleeve, a second screw, a steering rod, and a fastener. One end of the first screw can be detachably threaded to the embedded part, and the other end of the first screw extends into the interior of one end of the sleeve and is connected to the sleeve through the first through bolt. One end of the second screw is threaded to the inner wall of the other end of the sleeve, and the other end of the second screw is provided with a U-shaped head. A second through bolt is fixed on the two opposite side walls of the U-shaped head. The steering rod is rotatably connected to the second through bolt, and a fastener for fastening steel pipes is connected to the steering rod.

[0005] The beneficial effects of this utility model are as follows: The wall tie of this utility model, by setting an embedded part and detachably threading one end of the first screw to the embedded part, allows the embedded part to fit tightly against the wall structure. After removal, only the embedded part remains on the wall, resulting in smaller dimensions for later wall repairs and a better appearance of the exterior wall. The second screw has a rotatable steering rod connected to its U-shaped head, allowing the angle of the steering rod to be adjusted according to the arrangement of the steel pipes to be connected. This improves the safety, practicality, convenience, and flexibility of the wall tie operation, increases its turnover rate, and saves on hoisting costs.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a through-ring head hole is provided near one end of the sleeve, and an annular connector is provided at the other end of the first screw. The first through hole formed by the annular connector is arranged corresponding to the through-ring head hole and a first through bolt is inserted through it. The first through bolt is locked and fixed on the sleeve by a nut.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by opening a through-hole on the sleeve and setting an annular connector at the other end of the first screw, it is convenient to connect and fix the first screw and the sleeve.

[0009] Furthermore, a safety pin hole is provided near the other end of the sleeve, and a second through hole is provided at one end of the second screw. The second through hole is arranged correspondingly to the safety pin hole and a safety pin is inserted through it.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by opening a safety pin hole on the sleeve and opening a second through hole at one end of the second screw, it is convenient to connect and fix the sleeve and the second screw.

[0011] Furthermore, a section of the sleeve near the other end is a constricted section, the inner diameter of which is smaller than the inner diameter of other parts of the sleeve. The inner wall of the constricted section is provided with an internal thread structure, and the second screw is threadedly connected to the internal thread structure of the constricted section.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting a constricted structural section on the sleeve, it is convenient to make threaded connection with the second screw and also convenient to fix it through the first screw.

[0013] Furthermore, the safety pin hole is located on the sleeve and near the constricted structural section.

[0014] Furthermore, through bolt holes are provided on the two opposite sidewalls of the U-shaped head, and the second pair of through bolts are inserted and fixed in the through bolt holes.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by opening through bolt holes on the opposite side walls of the U-shaped head, it is convenient to connect and fix it with the second pair of through bolts.

[0016] Furthermore, the embedded part includes an implosion bolt housing and an implosion bolt support block, the implosion bolt support block being located inside the implosion bolt housing and used to open the implosion end of the implosion bolt housing; one end of the first screw is threadedly connected to the inner sidewall of the implosion bolt housing.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The embedded part uses an expansion bolt, including an implosion bolt housing and an implosion bolt support block. The implosion bolt support block, after being struck by a special jack, expands the implosion end of the expansion bolt housing, thereby widening the outer wall of the implosion end of the expansion bolt and tightly fitting it against the wall (structural beam), increasing the friction between the embedded part and the wall structure. When one end of the first screw is threaded into the implosion bolt housing, the implosion bolt support block is further pushed into the implosion end, further enhancing the tightness and reliability of the connection between the embedded part and the wall structure.

[0018] Furthermore, the diameter of the first screw is smaller than the inner diameter of the sleeve.

[0019] Furthermore, the first screw, the sleeve, and the second screw are arranged coaxially, the first through bolt is arranged perpendicular to the first screw, the second through bolt is arranged perpendicular to the second screw, and the first through bolt and the second through bolt are arranged perpendicular to each other.

[0020] This utility model also provides a scaffold, including a rear-mounted, angle-adjustable wall tie as described above to improve the appearance of exterior wall repairs, and also includes a wall, vertical steel pipes and horizontal steel pipes. The vertical steel pipes and horizontal steel pipes are connected to each other to form the scaffold body. The fasteners are clamped to the vertical steel pipes or the horizontal steel pipes. The turning rods are arranged horizontally or vertically, and the embedded parts are pre-embedded in the wall.

[0021] The beneficial effects of this utility model are: the scaffolding of this utility model is tightly and stably connected to the exterior wall, and also improves the appearance of the exterior wall after repair. Attached Figure Description

[0024] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] Example 1 like Figures 1-3 As shown in this embodiment, a rear-mounted, angle-adjustable wall tie that improves the aesthetics of exterior wall repair includes an embedded part, a first screw 1, a first through bolt 32, a sleeve 3, a second screw 2, a steering rod 4, and a fastener 5. One end of the first screw 1 can be detachably threaded to the embedded part, and the other end of the first screw 1 extends into one end of the sleeve 3 and is connected to the sleeve 3 via the first through bolt 32. One end of the second screw 2 is threaded to the inner wall of the other end of the sleeve 3, and the other end of the second screw 2 is provided with a U-shaped head 21. Second through bolts 23 are fixed on the two opposite sidewalls of the U-shaped head 21. The steering rod 4 is rotatably connected to the second through bolt 23, and a fastener 5 for fastening steel pipes is connected to the steering rod 4. The steering rod 4 can be horizontally connected or rotated to a vertical angle for connection, solving the problem of connecting horizontal and vertical steel pipes independently in the wall tie of a ground-mounted scaffold.

[0026] like Figure 1 and Figure 2 As shown, in one specific embodiment, the U-shaped head 21 has through bolt holes 22 on its two opposite sidewalls, and the second through bolt 23 passes through and is fixed in the through bolt holes 22. By opening through bolt holes on the opposite sidewalls of the U-shaped head, it is convenient to connect and fix it with the second through bolt.

[0027] Specifically, such as Figure 2 and Figure 3As shown, the embedded part in this embodiment is an expansion bolt. The embedded part includes an implosion bolt housing 6 and an implosion bolt support block 61. The implosion bolt support block 61 is located inside the implosion bolt housing 6 and is used to open the implosion end of the implosion bolt housing 6. One end of the first screw 1 is threadedly connected to the inner wall of the implosion bolt housing 6. The inner wall of the implosion bolt housing 6 is provided with internal threads 62. The embedded part adopts an expansion bolt, including an implosion bolt housing and an implosion bolt support block. The implosion bolt support block is opened by striking the implosion end of the expansion bolt housing with a special top rod, thereby expanding the outer wall of the implosion end of the expansion bolt and tightly fitting it to the wall (structural beam), increasing the friction between the embedded part and the wall structure. When one end of the first screw is threadedly connected to the implosion bolt housing, the implosion bolt support block is further pushed into the implosion end, further enhancing the tightness and reliability of the connection between the embedded part and the wall structure.

[0028] In this embodiment, the embedded part is an expansion bolt. The embedded part is installed in the structural beam of the wall by drilling holes in the wall. The iron block of the expansion bolt pushes the tail end of the expansion bolt shell from the inside to the outside, tightly fitting it in the structural beam of the wall, and generating sufficient tensile force through the threaded connection with the first screw.

[0029] Furthermore, such as Figure 1 As shown, in this embodiment, the diameter of the first screw 1 is smaller than the inner diameter of the sleeve 3. For example... Figures 1-3 As shown, in this embodiment, the first screw 1, sleeve 3 and second screw 2 are arranged coaxially, the first through bolt 32 is arranged perpendicular to the first screw 1, the second through bolt 23 is arranged perpendicular to the second screw 2, and the first through bolt 32 and the second through bolt 23 are arranged perpendicular to each other.

[0030] In this embodiment, the fastener 5 can be a clamp or clip commonly used in the construction field, which can achieve a tight connection with the steel pipe.

[0031] In this embodiment, the wall tie is first installed in the structural beam of the wall. Through implosion, the implosion bolt housing generates sufficient friction with the structural beam, ensuring sufficient tension in the threaded connection between the first screw and the implosion bolt housing. This ensures the wall tie is securely and reliably installed, preventing loosening and loss of tension during operation. The small diameter of the embedded part and its detachability from the first screw reduce the contact area between the wall tie and the exterior wall surface being repaired, minimizing the impact of repairs on the appearance of the repaired exterior wall and reducing the workload of workers repairing the contact surface. Furthermore, the second screw and sleeve are connected by threads, and the second screw and steering rod are connected by through bolts. This allows for flexible removal of the connections between the first screw and the structural beam, the first screw and the sleeve, and the second screw and the sleeve, further enhancing the ease and flexibility of operation, increasing the turnover rate of the wall tie, and saving on hoisting costs.

[0032] In this embodiment, the wall tie, by setting an embedded part and detachably threading one end of the first screw to the embedded part, allows the embedded part to fit tightly against the wall structure. After removal, only the embedded part remains on the wall, resulting in a small size for subsequent wall repairs and a better appearance of the exterior wall. The second screw has a rotatable steering rod connected to its U-shaped head, allowing the angle of the steering rod to be adjusted according to the arrangement of the steel pipes to be connected. This improves the safety, practicality, convenience, and flexibility of the wall tie operation, increases its turnover rate, and saves on hoisting costs.

[0033] Example 2 Based on Example 1, this example provides a preferred connection method between the sleeve and the first screw, such as... Figures 1-3 As shown, the sleeve 3 has a through-hole 31 near one end, and the other end of the first screw 1 has an annular connector 11. The first through hole formed by the annular connector 11 is arranged correspondingly to the through-hole 31 and a first through bolt 32 is inserted through it. The first through bolt 32 is locked onto the sleeve 3 by a nut. By opening the through-hole on the sleeve and providing the annular connector at the other end of the first screw, the connection and fixation between the first screw and the sleeve are facilitated.

[0034] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a preferred connection method between the sleeve 3 and the second screw 2, such as... Figures 1-3 As shown, the sleeve 3 has a safety pin hole 33 near its other end, and the second screw 2 has a second through hole at one end. The second through hole corresponds to the safety pin hole 33 and a safety pin 34 is inserted through it. By opening a safety pin hole on the sleeve and a second through hole at one end of the second screw, the connection and fixation between the sleeve and the second screw are facilitated.

[0035] like Figures 1-3 As shown, preferably, a section of the sleeve 3 near the other end is a tapered structural section 35. The inner diameter of the tapered structural section 35 is smaller than the inner diameter of other parts of the sleeve 3. The inner wall of the tapered structural section 35 is provided with an internal thread structure, and the second screw 2 is threadedly connected to the internal thread structure of the tapered structural section 35. By providing a tapered structural section on the sleeve, it is convenient to thread it to the second screw and also convenient to fix it through the first screw.

[0036] like Figures 1-3 As shown, the safety pin hole 33 is located on the sleeve 3 and near the constricted structural section 35.

[0037] Example 4 This embodiment provides a scaffold, including a rear-mounted, angle-adjustable wall tie as described above to improve the appearance of exterior wall repairs, as well as a wall body 8, vertical steel pipes and horizontal steel pipes 7. The vertical steel pipes and horizontal steel pipes 7 are connected to each other to form the scaffold body. The fasteners 5 are clamped to the vertical steel pipes or the horizontal steel pipes 7. The turning rods 4 are arranged horizontally or vertically, and the embedded parts are pre-embedded in the wall body 8.

[0038] The scaffolding in this embodiment is tightly and stably connected to the exterior wall, and it also improves the appearance of the repaired exterior wall.
