Description

Technical Field

[0001] This application relates to the field of wall ties, and more particularly to a rigid composite wall tie and its construction method. Background Technology

[0002] Outdoor scaffolding typically requires the installation of wall ties on the building's exterior walls. During subsequent scaffolding erection, the scaffolding is connected to the main building structure via these wall ties to enhance its overall stability and improve its load-bearing capacity.

[0003] In related technologies, such as Figure 1 The wall tie includes a wall tie rod 2, a connecting fastener 21, a connecting screw 22, and a connecting threaded sleeve 23. The connecting threaded sleeve 23 is embedded on the outside of the building structure beam 1. The wall tie rod 2 is fastened and fixed to the connecting fastener 21. The connecting screw 22 passes through the connecting fastener 21 and is threadedly connected to the embedded connecting threaded sleeve 23 to achieve the installation and fixation of the wall tie rod 2. When erecting scaffolding later, the uprights 20 of the scaffolding are fixed to the wall tie rod 2 to achieve the connection between the scaffolding and the wall tie.

[0004] For the aforementioned wall tie structure, subsequent scaffold loads (including scaffold self-weight load, construction load, and wind load) will be concentrated at the connection between the connecting bolt and the connecting threaded sleeve, which may cause fatigue damage to the connecting bolt and the connecting threaded sleeve, and in severe cases, deformation may even occur, posing certain safety hazards. Summary of the Invention

[0005] In order to improve the stress condition at the connecting bolt and connecting threaded sleeve on the wall tie, this application provides a rigid composite wall tie and its construction method.

[0006] This application provides a rigid composite wall tie and its construction method, which adopts the following technical solution:

[0007] A rigid composite wall tie includes a connecting wall tie rod, a connecting fastener, a connecting screw, a connecting threaded sleeve, and a plug-in sleeve; both the connecting threaded sleeve and the plug-in sleeve are pre-embedded in the outdoor side of the structural beam; one end of the wall tie rod near the structural beam is plugged into the plug-in sleeve and the wall tie rod is fastened and fixed in the connecting fastener; the connecting screw passes through the connecting fastener and is threadedly connected to the connecting threaded sleeve.

[0008] By adopting the above technical solution, after the scaffold uprights are installed on the wall ties, the scaffold load can be distributed to the connection between the plug sleeve and the wall tie, as well as the connection between the connecting screw and the connecting threaded sleeve. Compared with the traditional wall tie structure, this reduces the situation where the entire load of the scaffold is concentrated on the connection between the connecting screw and the connecting threaded sleeve, which can easily lead to deformation and damage of the connecting screw and the connecting threaded sleeve. This makes it easier for the scaffold uprights to be more securely connected to the wall ties.

[0009] Preferably, a connecting plate is provided between the threaded connecting sleeve and the insert sleeve, and both the threaded connecting sleeve and the insert sleeve are fixed to the connecting plate.

[0010] By adopting the above technical solution, it is easy to improve the connection integrity between the threaded sleeve and the plug sleeve through the connecting plate, so that the threaded sleeve and the plug sleeve are not prone to displacement or deformation.

[0011] Preferably, both the threaded sleeve and the plug sleeve are fixed to the steel mesh inside the structural beam by welding with connecting bars.

[0012] By adopting the above technical solution, the scaffold load acting on the connecting threaded sleeve and the plug sleeve can be transferred to the steel mesh of the structural beam through the connecting reinforcement, reducing the time that the scaffold load acts on the connecting threaded sleeve and the plug sleeve, thus preventing cracking at the connection between the connecting threaded sleeve and the plug sleeve and the concrete of the structural beam.

[0013] Preferably, both the connecting threaded sleeve and the insert sleeve are fitted with water-swellable sealing rings on their outer circumferences; the water-swellable sealing rings are located between the connecting plate and the connecting rib.

[0014] By adopting the above technical solution, the gap between the threaded sleeve and the plug sleeve and the concrete of the structural beam can be sealed by the water-swellable sealing ring. This reduces the possibility of external moisture seeping into the internal steel mesh of the structural beam through the gap between the threaded sleeve and the plug sleeve and the concrete of the structural beam, causing the steel bars of the structural beam to corrode.

[0015] Preferably, both the connecting threaded sleeve and the insert sleeve have annular limiting grooves corresponding to the water-swellable sealing rings, and the inner circumferences of the water-swellable sealing rings on the outer periphery of both the connecting threaded sleeve and the insert sleeve are embedded into the corresponding annular limiting grooves.

[0016] By adopting the above technical solutions, the displacement of the water-swellable sealing ring during the pouring of structural beams can be reduced.

[0017] Preferably, a construction method for a rigid composite wall tie includes the following steps:

[0018] S1: Tie the structural beam reinforcement; erect the structural beam formwork to form the cavity for casting the structural beam;

[0019] S2: Pre-embedded fixing of threaded sleeve and plug sleeve: The open ends of the threaded sleeve and plug sleeve are placed against the inside of the outdoor formwork of the structural beam, and the threaded sleeve and plug sleeve are temporarily fixed to the outdoor formwork of the structural beam by fasteners.

[0020] S3: Structural beam casting;

[0021] S4: Removal of templates and fasteners;

[0022] S5: Wall tie installation: Insert the end of the wall tie closest to the exterior side of the structural beam into the plug sleeve and fasten the wall tie to the connecting fastener. Finally, pass the connecting screw through the connecting fastener and thread the connecting screw to the connecting threaded sleeve.

[0023] By adopting the above technical solution, after the scaffold uprights are connected to the wall ties, the load of the scaffold can be distributed not only at the connection between the connecting bolt and the connecting threaded sleeve, but also at the connection between the wall tie and the plug pipe. This reduces the long-term concentrated load of the scaffold on the connection between the connecting bolt and the connecting threaded sleeve, which could easily lead to deformation and damage of the connecting bolt and the connecting threaded sleeve.

[0024] Preferably, the fastener includes a fastening screw, and the connecting plate has a threaded hole corresponding to the fastening screw for threaded connection of the fastening screw;

[0025] In step S2, the fastening screw is connected to the threaded hole, and a through hole is drilled on the outdoor template of the structural beam for the fastening screw to pass through. The fastening screw connected to the connecting plate is inserted into the through hole and the open ends of the connecting threaded sleeve and the insertion sleeve are made to abut against the inner side of the outdoor template of the structural beam. Then, a fastening nut is screwed into the end of the fastening screw that extends to the outer side of the outdoor template of the structural beam and the fastening nut is made to abut against the outer side of the outdoor template of the structural beam.

[0026] In step S5, when removing the structural beam formwork, unscrew the fastening nut from the fastening screw. After removing the formwork, unscrew the fastening screw from the connecting plate.

[0027] By adopting the above technical solution, the threaded sleeve and the plug sleeve can be temporarily fixed on the outdoor formwork of the structural beam. After the fastening nut and the formwork of the structural beam are removed, the fastening screw can be retrieved from the threaded hole on the connecting plate, which facilitates the reuse of the fastening screw.

[0028] Preferably, an annular sealing ring is provided on the side of the connecting plate near the open ends of both the connecting threaded sleeve and the insert sleeve; the connecting threaded sleeve, the insert sleeve, and the threaded hole are all located on the inner circumference of the annular sealing ring; when the open ends of both the connecting threaded sleeve and the insert sleeve abut against the inner side of the outdoor formwork of the structural beam, the annular sealing ring is tightly abutted against the inner side of the outdoor formwork of the structural beam.

[0029] By adopting the above technical solution, the gap between the connecting plate and the outdoor formwork of the structural beam is sealed by the annular sealing ring. This reduces the possibility that during subsequent pouring of the structural beam, concrete may come into contact with the fastening bolts through the gap between the connecting plate and the outdoor formwork of the structural beam, making it difficult to remove the fastening bolts from the connecting plate, or seeping into the interior of the connecting threaded sleeve and the insert sleeve, causing blockage of the connecting threaded sleeve and the insert sleeve.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By pre-embedding threaded sleeves and plug sleeves in the structural beams, when installing the wall tie rods, one end of the wall tie rod is inserted into the plug sleeve, and then it is fastened and fixed in the connecting fastener. Finally, the connecting bolts that pass through the connecting fasteners are threaded into the threaded sleeve. The subsequent scaffold loads can be distributed not only at the connection between the connecting bolt and the threaded sleeve, but also at the connection between the plug sleeve and the wall tie rod. This reduces the risk of deformation and damage to the connecting bolt and the threaded sleeve due to the concentrated scaffold load acting on the connection between the connecting bolt and the threaded sleeve.

[0032] 2. Both the connecting screw and the connecting threaded sleeve are welded and fixed to the steel mesh inside the structural beam through connecting bars. Subsequently, the load on the connecting threaded sleeve and the plug sleeve under scaffolding can be transferred to the steel mesh through the connecting bars, making the connecting threaded sleeve and the plug sleeve less prone to deformation under stress.

[0033] 3. An annular sealing ring is also provided on the side of the connecting plate near the open ends of the connecting threaded sleeve and the insert sleeve, and the annular sealing ring surrounds the connecting threaded sleeve and the insert sleeve. After the open ends of the connecting threaded sleeve and the insert sleeve are put against the outdoor formwork of the structural beam, the gap between the connecting plate and the outdoor formwork of the structural beam can be sealed by the annular sealing ring, which reduces the possibility of concrete seeping into the open ends of the connecting threaded sleeve and the insert sleeve and causing blockage when the structural beam is poured.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0043] This application discloses a rigid composite wall tie and its construction method, referring to... Figure 2 and Figure 3 The structure includes a wall tie rod 2, a connecting fastener 21, a connecting screw 22, a connecting threaded sleeve 23, and a plug sleeve 24. The connecting threaded sleeve 23 and the plug sleeve 24 are both embedded in the structural beam 1. One end of the wall tie rod 2 is inserted into the plug sleeve 24 and the wall tie rod 2 is fastened to the connecting fastener 21. The connecting screw 22 passes through the connecting fastener 21 and is threadedly connected to the connecting threaded sleeve 23.

[0044] With the above settings, after the scaffold uprights 20 are connected to the wall ties 2, the scaffold load can be distributed at the connection between the connecting bolts 22 and the connecting threaded sleeves 23, as well as at the connection between the wall ties 2 and the plug sleeves 24. This reduces the long-term concentration of scaffold load at the connection between the connecting bolts 22 and the connecting threaded sleeves 23, which could easily cause the connecting bolts 22 and the connecting threaded sleeves 23 to deform and be damaged.

[0045] In this embodiment, the connecting fastener 21 is an existing single-sided steel pipe fastener. The connecting fastener 21 has a protruding mounting part 211 on its outer periphery. The mounting part 211 has a through hole for the connecting screw 22 to pass through. The connecting screw 22 passes through the through hole and into the mounting part 211, so that the connecting screw 22 passes through the connecting fastener 21.

[0046] Reference Figure 4 and Figure 5 Both the threaded sleeve 23 and the plug sleeve 24 are welded and fixed to the steel mesh 10 inside the structural beam 1 via the connecting bar 25; this allows the scaffold load acting on the threaded sleeve 23 and the plug sleeve 24 to be transferred to the steel mesh 10 of the structural beam 1, reducing the likelihood of concrete cracking around the threaded sleeve 23 and the plug sleeve 24 when the scaffold load acts on them for a long time.

[0047] Reference Figure 5 and Figure 6 A connecting plate 3 is also provided between the threaded sleeve 23 and the insert sleeve 24. The connecting plate 3 is located at the open ends of the threaded sleeve 23 and the insert sleeve 24. Both the threaded sleeve 23 and the insert sleeve 24 are fixed on the connecting plate 3, which helps to improve the connection integrity between the threaded sleeve 23 and the insert sleeve 24.

[0048] Both the threaded sleeve 23 and the insert sleeve 24 are coaxially fitted with water-swellable sealing rings 4 on their outer circumferences. The water-swellable sealing rings 4 are located between the connecting rib 25 and the connecting plate 3. By setting the water-swellable sealing rings 4, the water-swellable sealing rings 4 seal the gaps between the threaded sleeve 23 and the insert sleeve 24 and the structure, reducing the possibility of external moisture seeping into the connecting rib 25 and the steel mesh 10 inside the structural beam 1 through the gaps between the threaded sleeve 23 and the insert sleeve 24 and the structural beam 1, thus preventing corrosion and damage to the connecting rib 25 and the steel mesh 10.

[0049] An annular limiting groove 41 is provided on the outer periphery of both the threaded sleeve 23 and the insert sleeve 24; the inner periphery of the two water-swellable sealing rings 4 are embedded in the annular limiting groove 41 on the outer periphery of both the threaded sleeve 23 and the insert sleeve 24 to limit the water-swellable sealing rings 4, so as to reduce the possibility of displacement and detachment of the water-swellable sealing rings 4 on the outer periphery of both the threaded sleeve 23 and the insert sleeve 24 when the structural beam 1 is poured.

[0050] A construction method for rigid composite wall ties, referring to Figure 4 and Figure 5 This includes the following steps:

[0051] S1: Tie the reinforcing bars of structural beam 1 and set up formwork 11 for structural beam 1 to form the mold cavity for casting structural beam 1.

[0052] S2: Pre-embedded fixing of threaded sleeve 23 and plug sleeve 24: The open ends of threaded sleeve 23 and plug sleeve 24 are abutted against the inner side of the outdoor formwork 11 of structural beam 1; threaded sleeve 23 and plug sleeve 24 are temporarily fixed to the outdoor formwork 11 of structural beam 1 by fasteners.

[0053] The fastener includes four sets of fastening screws 33. The connecting plate 3 has four sets of threaded holes 32 on one side near the open end of the connecting threaded sleeve 23 and the insertion sleeve 24, corresponding to the four sets of fastening screws 33.

[0054] The specific steps of S2 are as follows:

[0055] S2.1: Connect the four sets of fastening screws 33 to the four sets of threaded holes 32 on the connecting plate 3 respectively;

[0056] S2.2: Drill four sets of through holes on the outdoor side formwork 11 of structural beam 1 for fastening bolts 33 to pass through;

[0057] S2.3: Move the connecting plate 3 so that the open ends of the connecting threaded sleeve 23 and the insertion sleeve 24 abut against the inner side of the outdoor side template 11 of the structural beam 1 and the four sets of fastening screws 33 on the connecting plate 3 pass through the corresponding through holes on the outdoor side template 11 of the structural beam 1.

[0058] S2.4: Screw in the fastening nut at the end of each set of fastening screws 33 that extends out of the outdoor side template 11 of the structural beam 1, and rotate the fastening nut until it abuts against the outside of the outdoor side template 11 of the structural beam 1, so as to temporarily fix the connecting threaded sleeve 23 and the plug sleeve 24 to the outdoor side template 11 of the structural beam 1.

[0059] S2.5: The threaded sleeve 23 and the plug sleeve 24 are welded and fixed to the steel mesh 10 of the structural beam 1 by the connecting bar 25.

[0060] S3: Structural beam 1 is poured; it is worth noting that during the pouring of structural beam 1, when the concrete in the mold cavity is vibrated by the vibrator, the vibrator must not come into contact with the threaded sleeve 23 and the plug sleeve 24.

[0061] S4: Removal of formwork 11 and fasteners for structural beam 1; specific steps are as follows:

[0062] S4.1: Unscrew the fastening nut from the fastening screw 33;

[0063] S4.2: Remove the formwork 11 at all points around the outer perimeter of structural beam 1;

[0064] S4.3: Unscrew the fastening screw 33 from the connecting plate 3 to recycle the fastening screw 33.

[0065] S5: Installation of wall tie rod 2: Insert the end of the wall tie rod 2 near the outdoor side of the structural beam 1 into the plug sleeve 24 and fasten and fix the wall tie rod 2 onto the connecting fastener 21. Finally, pass the connecting screw 22 through the connecting fastener 21 and thread the connecting screw 22 into the connecting threaded sleeve 23.

[0066] An annular sealing ring 31 is fixed to one side of the connecting plate 3 near the open ends of the connecting threaded sleeve 23 and the insertion sleeve 24. In this embodiment, the annular sealing ring 31 is a rubber sealing ring. The connecting threaded sleeve 23, the insertion sleeve 24, and the four sets of threaded holes 32 on the connecting plate 3 are all located on the inner circumference of the annular sealing ring 31. When the open ends of the connecting threaded sleeve 23 and the insertion sleeve 24 abut against the inner side of the outdoor formwork 11 of the structural beam 1, the annular sealing ring 31 is tightly abutted against the inner side of the outdoor formwork 11 of the structural beam 1. With the above settings, the gap between the connecting plate 3 and the inner side of the outdoor formwork 11 of the structural beam 1 can be sealed by the annular sealing ring 31. This limits the situation where, when pouring concrete for the structural beam 1, the concrete adheres to the fastening screw 33 through the gap between the connecting plate 3 and the outdoor formwork 11 of the structural beam 1, making it difficult to unscrew the fastening screw 33 from the connecting plate 3, or causing it to seep into the connecting threaded sleeve 23 and the insertion sleeve 24, resulting in blockage of the connecting threaded sleeve 23 and the insertion sleeve 24.

[0067] This application involves pre-embedding a plug-in sleeve 24 on the structural beam 1. When installing and fixing the wall tie 2, the end of the wall tie 2 closest to the structural beam 1 is inserted into the plug-in sleeve 24, and then the wall tie 2 is fastened to the connecting fastener 21. Finally, the connecting screw 22, which passes through the connecting fastener 21, is threadedly connected to the connecting threaded sleeve 23. After the scaffold uprights 20 are subsequently connected and fixed to the wall tie 2, the scaffold load can be distributed across the connection points of the connecting screw 22 and the connecting threaded sleeve 23, as well as the connection point between the wall tie 2 and the plug-in sleeve 24. This helps reduce the long-term concentrated load on the connecting screw 22 and the connecting threaded sleeve 23, which could easily cause deformation and damage. Consequently, the wall tie 2 can be more securely installed on the outdoor side of the structural beam 1.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
