Description

Technical Field

[0001] The utility model relates to the technical field of building engineering wall connecting pieces, in particular to a rotatable double-fastener type external frame wall connecting piece. Background Art

[0002] In the construction process of building projects, scaffolding works play a vital role as a safety facility for enclosure. The traditional embedded parts method usually involves pre-embedding steel pipes in the cast-in-place beams of the structure and connecting them with the vertical poles to form a stable overall structure. However, this method has exposed several significant drawbacks in practical applications.

[0003] First, the traditional method of pre-embedded steel pipes requires cutting after the cast-in-place beams are formed. This process not only increases labor costs, but also leads to waste of steel pipes, because the cut steel pipes often cannot be reused. In addition, the repair work of the pre-embedded steel pipe part also adds additional construction time and cost, and the repaired part may have an adverse effect on the waterproof quality of the structure itself. Secondly, the external frame wall parts in the existing conventional technology usually adopt an integral pre-embedded type, in which the steel pipes are pre-embedded on the beams, and the gable parts are set through the wall through the pre-embedded sleeves. Although this method meets the construction needs to a certain extent, there are still many problems in practical applications. For example, during the masonry process, it is necessary to avoid the position of the wall parts, which may make the later brick plugging and sealing work complicated, seriously affecting the quality and efficiency of the exterior wall decoration construction. In addition, the wall sleeves set in the gable shear wall part use self-compacting concrete for later plugging, but this method has the risk of leakage and may damage the overall waterproof performance of the building. Furthermore, the setting standard of wall ties is generally two steps and three spans. For high-rise buildings with a height of more than 50 meters, especially in typhoon-intensive areas, a more dense setting of two steps and two spans is required. However, this setting method also brings certain problems. For example, the setting height of the wall tie must not exceed the limit of 300mm of the main node of the external frame, which may lead to the inability to meet construction requirements in some cases. In addition, the wall tie parts need to be repaired when the frame is dismantled, which not only affects the construction period, but also adds additional costs. Utility Model Content

[0038] The fixing bolt 1 is fixedly connected to the embedded device 3 embedded in the concrete 5;

[0039] The two fasteners 2 are detachably connected to the transverse steel pipe 4 of the outer frame.

[0040] In this embodiment, the rotatable double-fastener type external frame wall connection member includes a fixing bolt 1 and two fasteners 2 fixed to the outer wall of the fixing bolt 1; the fixing bolt 1 serves as the main part of the connection, and the fixing bolt 1 is responsible for tightly connecting the wall connection member to the main structure of the building. The embedded device 3 is pre-embedded in the concrete 5 as a fixing point for the fixing bolt 1; preferably, the fixing bolt 1 adopts a high-strength bolt with a diameter of 20 mm.

[0041] The two fasteners 2 are respectively fixed on the outer wall of the fixing bolt 1. The main function of the fastener 2 is to be detachably connected to the transverse steel pipe 4 of the outer frame to ensure the stability and safety of the scaffolding frame. The two fasteners 2 enhance the firmness of the connection and avoid the potential safety hazards caused by using a single fastener. The transverse steel pipe 4 is one of the main components of the scaffolding frame and is connected to the wall connecting piece through the fastener 2.

[0042] The utility model adopts a double fastener design, which enhances the firmness and stability of the connection and avoids the potential safety hazards caused by using a single fastener. The utility model reduces the later repair work and improves the construction efficiency. The utility model can effectively prevent water seepage in the exterior wall and ensure the waterproof performance of the building structure.

[0043] Figure 2 The structure of the embedded device of one embodiment of the utility model is shown in FIG. Figure 1 ; Figure 3 The structure of the embedded device of one embodiment of the utility model is shown in FIG. Figure 2 .like Figure 2 and Figure 3As shown, according to an embodiment of the present utility model, the embedded device 3 includes: a sleeve 31, a concrete anchoring section 32 and a template reinforcement section 33 respectively located at both ends of the sleeve 31;

[0044] The concrete anchoring section 32 is pre-embedded in the concrete 5;

[0045] The template reinforcement section 33 and the reinforcement bolts 34 are screwed together to clamp the template 6;

[0046] The concrete anchoring section 332 further includes a fixing nut 321 and a first reinforcing wing plate 322;

[0047] The fixing nut 321 is arranged at one end of the concrete anchoring section 32 away from the template reinforcement section 33, and the fixing nut 321 can be screwed with the reinforcement bolt 34, and the fixing nut 321 can be screwed with the fixing bolt 1;

[0048] The first reinforcing wing plate 322 is used to increase the connection between the fixing nut 321 and the sleeve 31 .

[0049] In this embodiment, the embedded device 3 includes a sleeve 31, a concrete anchoring section 32 and a template reinforcement section 33 respectively located at both ends of the sleeve 31;

[0050] The sleeve 31 is the main part of the entire embedded device 3. The two ends of the sleeve 31 are respectively connected to the concrete anchoring section 32 and the formwork reinforcement section 33. The concrete anchoring section 32 is the part embedded in the concrete 5. Its design ensures the firm connection between the embedded device 3 and the concrete structure.

[0051] The concrete anchoring section 32 includes a fixing nut 321 and a first reinforcing wing plate 322. The fixing nut 321 is arranged at one end of the concrete anchoring section 32 away from the template reinforcing section 33 and has dual functions. First, it can be screwed with the reinforcing bolt 34 to reinforce the template 6; second, it can also be screwed with the fixing bolt 1 to achieve a tight connection between the wall connecting member and the embedded device 3. The first reinforcing wing plate 322 is used to increase the connection strength between the fixing nut 321 and the sleeve 31 to ensure that the connection between the fixing nut 321 and the sleeve 31 will not loosen or break when subjected to external force.

[0052] The template reinforcement section 33 is screwed with the reinforcement bolt 34 to clamp the template 6 to ensure that the template 6 maintains a stable and accurate position during the construction process. Through the coordinated use of the template reinforcement section 33 and the reinforcement bolt 34, the template 6 can be effectively reinforced to improve the construction quality and safety.

[0053] The utility model ensures that the connection between the embedded device and the concrete structure is firm and reliable through the embedding of the concrete anchoring section and the fixing of the fixing nut. The use of the template reinforcement section and the reinforcement bolt of the utility model makes the template reinforcement more convenient and quick, and improves the construction efficiency. The first reinforcing wing plate of the utility model increases the connection strength between the fixing nut and the sleeve, further improving the safety and reliability of the entire embedded device.

[0054] According to an implementation of the present utility model, the sleeve 31 is made of a high-strength plastic sleeve.

[0055] In this embodiment, a high-strength plastic sleeve is used as the sleeve 31, which reduces the cost compared with the traditional steel pipe pre-embedded, and the plastic sleeve is easier to process. Preferably, the inner wall of the sleeve 31 is provided with a thread matching the fixing bolt 1 and the adjusting bolt 24, thereby enhancing the connection stability of the sleeve 31 and the fixing bolt 1 and the adjusting bolt 24.

[0056] The utility model has a simple structure and low manufacturing cost.

[0057] According to an embodiment of the utility model, an anti-slip fixing plate 7 is provided on one side of each fastener 2 , and the anti-slip fixing plate 7 is sleeved on the outer wall of the fixing bolt 1 , and the anti-slip fixing plate 7 is used to increase the lateral displacement resistance of the fastener 2 .

[0058] In the present embodiment, an anti-slip fixing plate 7 is provided on the outer wall of the fixing bolt 1 adjacent to the fastener 2, thereby increasing the lateral displacement resistance of the fastener 2; the anti-slip fixing plate 7 has a fixing through hole, the size of the fixing through hole matches the outer diameter of the fixing bolt 1, thereby ensuring that the anti-slip fixing plate 7 is stably connected to the outer wall of the fixing bolt 1; preferably, the anti-slip fixing plate 7 is made of a 10 mm thick steel plate.

[0059] The utility model significantly increases the lateral displacement resistance of the fastener and improves the stability of the structure by arranging an anti-slip fixing sheet sleeved on the outer wall of the fixing bolt on one side of the fastener.

[0060] Figure 4 FIG. 1 is a schematic diagram of the structure of a fastener according to an embodiment of the present utility model. Figure 4 As shown, according to an embodiment of the present utility model, the fastener 2 includes: a fastener body 21, an arc-shaped fixing plate 22;

[0061] The fastener body 21 is provided with a through hole 23 for passing the fixing bolt 1;

[0062] One end of the fastener body 21 is rotatably connected to the arc-shaped fixing plate 22, and the other end is provided with an adjusting bolt 24;

[0063] The arc-shaped fixing plate 22 is provided with a U-shaped groove matching the adjusting bolt 24. When the adjusting bolt 24 is fixedly connected with the U-shaped groove, the transverse steel pipe 4 is fixed between the fastener body 21 and the arc-shaped fixing plate 22.

[0064] The position on the fastener body 21 corresponding to the arc-shaped fixing plate 22 is set as an arc-shaped surface 25;

[0065] The inner surface of the arc-shaped fixing plate 22 and the surface of the arc-shaped surface 25 are both provided with anti-slip pads.

[0066] In this embodiment, the fastener 2 includes a fastener body 21 and an arc-shaped fixing plate 22; the fastener body 21 is the main part of the entire fastener, which provides a platform to connect and fix other components. The fastener body 21 is provided with a through hole 23, and the through hole 23 is used to pass the fixing bolt 1; the arc-shaped fixing plate 22 is used to adapt to and fix the shape of the transverse steel pipe 4. Since the steel pipe is usually round, the arc-shaped design can better fit the steel pipe and increase stability. The arc-shaped fixing plate 22 is rotatably connected to one end of the fastener body 21, which allows the arc-shaped fixing plate 22 to rotate relative to the fastener body 21 to adapt to transverse steel pipes 4 of different sizes. The arc-shaped fixing plate 22 is provided with a U-shaped groove, which is used to cooperate with the adjustment bolt 24, and the transverse steel pipe 4 is locked by fixing the adjustment bolt 24. The adjustment bolt 24 is a key component connecting the fastener body 21 and the arc-shaped fixing plate 22. The design of the adjustment bolt 24 allows the user to make fine adjustments as needed to ensure that the transverse steel pipe 4 is firmly fixed in the desired position.

[0067] The position on the fastener body 21 corresponding to the arc-shaped fixing plate 22 is set as an arc-shaped surface 25, which helps to increase the contact area between the fastener 2 and the transverse steel pipe 4 and improve stability. The arc-shaped surface 25 and the arc-shaped fixing plate 22 together form a complete circular or approximately circular space for accommodating and fixing the transverse steel pipe 4.

[0068] Anti-skid pads are provided on the inner surface of the arc-shaped fixing plate 22 and the surface of the arc-shaped surface 25. These anti-skid pads can be made of rubber or other high-friction materials. The main function of the anti-skid pads is to increase the friction between the steel pipe and the fastener to prevent the transverse steel pipe 4 from sliding or shifting when subjected to external force.

[0069] The fastener of the utility model improves the stability and safety of steel pipe fixation; through the cooperation of the through hole of the fastener body and the fixing bolt, and the linkage mechanism between the arc-shaped fixing plate and the adjusting bolt, the fastener can flexibly adapt to transverse steel pipes of different sizes, and enhance the friction between the fastener and the steel pipe through the anti-skid pad, effectively preventing the steel pipe from sliding or shifting, and ensuring that the steel pipe is firmly fixed in the desired position.

[0070] Working principle:

[0071] Figure 5This is a schematic diagram of the connection of a revolvable double-fastener type external frame wall connecting member in one embodiment of the utility model. Figure 5 As shown, the technical process of the utility model is: install the embedded device 3 → pour concrete 5 → install the revolving double-fastener type external frame wall connecting piece → connect the horizontal steel pipe 4 to fix the wall connecting piece

[0072] Install the embedded device 3: First, position it according to the external frame pole, draw lines and make holes on the aluminum film plate or wooden template. The hole φ is 22mm. Place the embedded high-strength plastic sleeve 31 in the wall or beam, and clamp the template 6 with reinforcement bolts 34 on the outside. Ensure that the concrete anchor section 32 and sleeve 31 do not shift or lose during the pouring process. It is not advisable to install the anchor too early. It can be placed after all the steel bars are tied. Some parts with dense steel bars can be placed in advance. While pouring the concrete 5, a special person should be assigned to check to prevent the anchor from shifting and sliding. If there is any missing, it should be replaced immediately.

[0073] Concrete 5 pouring: When pouring concrete 5, it should be avoided that the concrete 5 directly impacts the concrete anchoring section 32 and the sleeve 31 during the falling process to prevent the anchor from being washed away by the concrete 5. Therefore, when vibrating the concrete 5, a certain distance should be maintained from the anchor, and the vibrating rod should not touch the anchor to ensure the placement quality of the anchor.

[0074] Install the revolvable double-fastener type external frame wall connection: After the template 6 is removed, the revolvable double-fastener type external frame wall connection can be installed when the concrete strength reaches 15Mpa. When installing, first remove the reinforcement bolts 34 and screw them out. Use a hair dryer to clean the embedded parts to ensure that there are no debris when the fixing bolts 1 are screwed in and there is no obstruction when tightening. Screw the fixing bolts 1 into the pre-buried high-strength plastic sleeve.

[0075] Connect the crossbars to fix the wall parts: first insert the transverse steel pipe 4 into the revolvable double-fastener external frame wall parts. The fastener 2 does not need to be tightened for the first time, and it remains movable and retractable. Then connect the transverse steel pipe 4 to the inner and outer rods of the external frame. First ensure that the external frame vertical rods are firmly connected and then tighten the revolvable double-fastener external frame wall parts.

[0076] The utility model uses a revolvable double-fastener type external frame wall connection piece, which not only ensures that the scaffolding frame is firmly and reliably connected to the main structure of the building, but also facilitates the external wall construction, and can be completed in one step when the masonry structure construction and external wall plastering and finishing construction are carried out. When the frame is dismantled, there is no need to repair the masonry and plastering, and it will not cause water seepage in the external wall. The embedded full-turnover wall connection piece can be disassembled and reused, and the turnover rate is efficient and the cost is reduced. There are safety risks such as high-altitude work and falling objects in the process of traditional wall connection piece construction and dismantling. The embedded wall connection piece can avoid these risks due to the setting of the pre-embedded structure, reduce the accidental injury and accident rate during the construction process, and reduce the corresponding compensation and maintenance costs.

[0077] The utility model provides a rotatable double-fastener type external frame wall connecting piece, which solves the problem of workers using single fasteners due to unsupervised construction. It not only ensures that the scaffold frame is firmly and reliably connected to the main structure of the building, but also facilitates the external wall construction, and the masonry structure construction and the external wall plastering and finishing construction can be completed in one step. When the frame is dismantled, there is no need to repair the masonry and plastering, and it will not cause water seepage in the external wall.
