Description

Technical Field

[0001] This application relates to the technical field of curtain wall installation auxiliary equipment, and in particular to a device for preventing the offset of curtain wall embedded parts. Background Art

[0002] A curtain wall is the external wall enclosure of a building, which does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. It is composed of a panel and a support structure system, and can have a certain displacement ability relative to the main structure or have a certain deformation ability itself, and does not bear the action of the main structure. It is an external enclosure structure or decorative structure of a building.

[0003] At present, curtain walls are generally installed in the building main body by using embedded parts. The embedded parts are divided into pre-embedded parts and post-embedded parts. The pre-embedded parts generally include steel plates and anchoring components arranged on the steel plates. When installing the pre-embedded parts, the anchoring components are fixedly connected to the steel bar framework of the building main body, usually by welding. Then, a formwork system is built to surround the steel bar framework, and the steel plate is abutted against the surface of the formwork. Then, concrete is poured into the formwork system. When the concrete sets, the formwork is removed to complete the construction of the embedded parts. The construction process of the post-embedded parts is generally to drill holes in the already formed building main body, then drive mechanical bolts or chemical bolts into the holes, and then fix the steel plate on the bolts through nuts to complete the installation of the embedded parts. The pre-embedded parts have better performance such as bearing capacity and shear resistance than the post-embedded parts. Therefore, in curtain wall projects, pre-embedded parts are usually used to hang the curtain wall.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: after the embedded part is welded to the steel bar framework, when the concrete is poured, the concrete impacts on the steel bar framework or the anchoring components, which will drive the steel plate to vibrate or shift. As a result, after the concrete sets, the position of the steel plate deviates, making it difficult to meet the subsequent construction of the curtain wall. Summary of the Invention

[0005] In order to reduce the possibility of the offset of the embedded part, this application provides a device for preventing the offset of curtain wall embedded parts.

[0006] A device for preventing the offset of curtain wall embedded parts provided by this application adopts the following technical solution:

[0007] A device for preventing the offset of curtain wall embedded parts, including a fixing plate, the fixing plate is used to pass through the anchoring component, the fixing plate includes two spliced plates, and notches for the anchoring component to move into are provided on both of the two spliced plates. After the two spliced plates are spliced together, the notches are communicated. After the two spliced plates are spliced together, the anchoring component is located in the notch. The offset prevention device further includes a first fixing member for fixing the two spliced plates in a spliced state; connecting plates are rotatably provided at both ends of the spliced plate along the height direction of the steel bar framework, and the rotation axis of the connecting plate is parallel to the plane where the spliced plate is located, and the free end of the connecting plate is used to be fixed on the formwork.

[0008] By adopting the above technical solution, after the steel bar framework is installed, the anchoring component of the embedded part is welded on the steel bar framework, then the two spliced plates are sleeved on the anchoring component, and then the two spliced plates are spliced. Subsequently, the two spliced plates are spliced into a whole by the first fixing member, and then the formwork is laid, so that the steel plate of the embedded part abuts against the formwork. Then the connecting plate is rotated so that the end of the connecting plate abuts against the formwork. Finally, the free end of the connecting plate is fixed on the formwork to complete the fixing of the embedded part. Then the concrete is poured into the space surrounded by the formwork to complete the embedding of the embedded part; during the pouring process of the concrete, the concrete acts on the stirrups of the steel bar framework, and the stirrups deflect and bend downward, driving the anchoring component welded to it to deflect downward, and then driving the steel plate to deflect away from the formwork. In the above process, under the action of the fixing plate, the anchoring components of the embedded part are connected into a whole, improving the anti-bending performance of the anchoring component, reducing the possibility of the steel plate deflecting away from the formwork, and improving the embedding quality of the embedded part; at the same time, under the impact of the concrete, the anchoring component may bend. Under the action of the connecting plate, the connecting plate above the spliced plate pulls the spliced plate, and the connecting plate below the spliced plate supports the spliced plate, thereby reducing the possibility of the spliced plate deflecting; the spliced plate plays a limiting role on the anchoring component, thereby reducing the possibility of the anchoring component bending and deflecting, and thus reducing the possibility of the steel plate deflecting, further improving the embedding quality of the embedded part; after the concrete sets, the fixing plate is located in the concrete. When the embedded part bears the curtain wall, the possibility of the anchoring component slipping is reduced, and the stability of the anchoring component is improved.

[0009] Optionally, connecting shafts are fixedly provided at both ends of the spliced plate along the height direction of the steel bar framework, the connecting plates are sleeved on the connecting shafts, and pins are detachably provided on the connecting shafts, and the ends of the connecting plates abut against the pins.

[0010] By adopting the above technical solution, after the two splicing plates are clamped on the anchoring assembly, the direction of the connecting plate is adjusted. Subsequently, the connecting plate is inserted into the connecting shaft, then the pin is inserted into the connecting shaft, and finally the free end of the connecting plate is fixed on the formwork. Inserting the connecting plate onto the connecting shaft facilitates the fixed connection of the connecting plate to the formwork and reduces the influence of the stirrup on the rotation of the connecting plate. Under the action of the pin, the possibility of the connecting plate falling off the connecting shaft is reduced.

[0011] Optionally, the length direction of the pin is parallel to the plane where the splicing plate is located and is arranged facing the splicing plate. The pin is rotatably arranged on the connecting shaft, and a threaded section is provided on the pin. A threaded hole for threaded connection of the threaded section is provided on the splicing plate.

[0012] By adopting the above technical solution, after the connecting plate is inserted into the connecting shaft, the pin is rotated so that the pin is threadedly connected in the threaded hole. Under the action of the pin, both ends of the connecting shaft are effectively connected to the abutting plate, reducing the possibility of the connecting shaft bending in the direction away from the abutting plate, improving the pulling effect of the connecting plate on the splicing plate, further reducing the possibility of the anchoring assembly shifting, and further reducing the possibility of the embedded part shifting.

[0013] Optionally, a mounting plate is hinged to the free end of the connecting plate. The rotation axis of the mounting plate is parallel to the rotation axis of the connecting plate. The mounting plate rotates to be parallel to the plane where the formwork is located and abuts against the formwork. Iron nails are provided on the surface of the mounting plate facing away from the formwork. The length direction of the iron nails is perpendicular to the plane where the mounting plate is located, and the iron nails are used to nail into the formwork.

[0014] By adopting the above technical solution, after the free end of the connecting plate abuts against the formwork, the mounting plate is rotated so that the mounting plate lies flat on the formwork, and then the iron nails are nailed into the formwork to complete the fixation of the connecting plate. Under the action of the mounting plate, it is convenient for the mounting plate to fit on the formwork so that the iron nails can be nailed into the formwork. The iron nails enter the formwork in a direction perpendicular to the formwork, which is convenient for the later removal of the formwork.

[0015] Optionally, the first fixing member includes a screw rod rotatably arranged on the splicing surface of the splicing plate. A threaded groove for threaded connection of the screw rod is provided on the other splicing plate.

[0016] By adopting the above technical solution, after the two splicing plates are spliced together, the screw rod is rotated and the screw rod enters the threaded groove, thereby connecting the two splicing plates into a whole. The operation is simple and convenient. At the same time, the screw rod has the advantages of good fixing effect on the two splicing plates.

[0017] Optionally, the offset prevention device further includes a abutting block. The abutting block is used to move into the notch and abut and support the adjacent anchoring assembly after the two splicing plates are spliced. The surface of the abutting block close to the inner wall of the notch abuts against the inner wall of the notch.

[0018] By adopting the above technical solution, after the two splicing plates are spliced ​​into a whole, the abutment block is moved into the notch, and the two ends of the abutment block abut on the anchor assembly. Under the action of the abutment block, the possibility of lateral displacement of the anchor assembly is reduced, thereby further reducing the possibility of separation of the steel plate and the template, and further reducing the possibility of displacement of the embedded parts.

[0019] Optionally, the end surface of the abutment block for abutting the anchoring assembly is concavely provided with an arc groove, the arc of the arc groove is greater than π, and the anchoring assembly is located in the arc groove.

[0020] By adopting the above technical solution, after the abutment block moves into the notch, the anchor assembly is clamped in the arc groove. Under the action of the arc groove, the jumping of the anchor assembly is limited, thereby reducing the possibility of the anchor assembly causing the jumping of the anchor assembly during the concrete feeding process, and further reducing the possibility of the embedded parts being offset.

[0021] Optionally, a support rod is rotatably provided on the connecting plate close to the steel plate, the rotation axis of the support rod is parallel to the rotation axis of the connecting plate, the support rod is a telescopic structure, and an abutment ring is provided at the end of the support rod away from the connecting plate, the area of ​​the abutment ring is larger than the cross-sectional area of ​​the support rod, and the abutment ring is used to abut against the steel plate.

[0022] By adopting the above technical scheme, when concrete impacts the connecting plate, there is a possibility that the connecting plate is bent. At the same time, the connecting plate applies a thrust in the direction away from the formwork toward the fixed plate, which may easily cause the steel plate to deviate in the direction away from the formwork; under the action of the support rod, when the connecting plate is bent, the connecting plate applies a thrust in the direction of the formwork toward the support rod, thereby pushing the steel plate to abut against the formwork, further reducing the possibility of displacement of the embedded parts; under the action of the abutment ring, the possibility of the support rod and the steel plate falling off is reduced; the support rod is located below the connecting plate, which reduces the possibility of concrete directly impacting the support rod and reduces the possibility of the support rod and the steel plate falling off.

[0023] Optionally, the support rod includes a sleeve rod hinged on the connecting plate and a sliding rod threadedly connected inside the sleeve rod, and the abutment ring is rotatably arranged on the end of the sliding rod.

[0024] By adopting the above technical solution, after rotating the support rod to be perpendicular to the plane where the steel plate is located, the sliding rod is rotated, and the sliding rod drives the abutment ring to slide toward the direction of the steel plate. The abutment ring abuts against the steel plate, and the operation is simple and convenient; at the same time, it is easy to fix the abutment ring at the above position.

[0025] Optionally, reinforcing ribs are provided on the surface of the connecting plate facing away from the steel plate, and the length direction of the reinforcing ribs is parallel to the length direction of the connecting plate.

[0026] By adopting the above technical solution, under the action of the reinforcing rib, the possibility of the connecting plate bending is reduced, the supporting effect of the connecting plate on the fixing plate is improved, and the possibility of the embedded part shifting is further reduced.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. During the concrete pouring process, the concrete acts on the stirrups of the steel bar framework. The stirrups shift and bend downward, driving the anchoring component welded to it to shift downward, and then driving the steel plate to shift away from the formwork. During the above process, under the action of the fixing plate, the anchoring components of the embedded part are connected into a whole, improving the bending resistance of the anchoring components, reducing the possibility of the steel plate shifting away from the formwork direction, and improving the embedding quality of the embedded part;

[0029] 2. Under the impact of the concrete, there is a possibility that the anchoring component bends. Under the action of the connecting plate, the connecting plate above the splicing plate pulls the splicing plate, and the connecting plate below the splicing plate supports the splicing plate, thereby reducing the possibility of the splicing plate shifting. The splicing plate plays a limiting role on the anchoring component, thereby reducing the possibility of the anchoring component bending and shifting, and thus reducing the possibility of the steel plate shifting, further improving the embedding quality of the embedded part;

[0030] 3. After the concrete sets, the fixing plate is located inside the concrete. When the embedded part bears the curtain wall, the possibility of the anchoring component slipping is reduced, and the stability of the anchoring component is improved. Description of the Drawings

[0045] The embodiment of this application discloses a device for preventing the offset of curtain wall embedded parts. Refer to Figure 3 and Figure 4 , the device for preventing the offset of curtain wall embedded parts includes a fixed plate 3. In the embodiment of this application, the fixed plate 3 is a rectangular plate. The fixed plate 3 is used to pass through the connecting steel bars 12 of the anchoring component. The fixed plate 3 includes two mutually spliced splicing plates 31. Notches 4 for the anchoring component to move in are provided on both splicing plates 31. One end of the notch 4 penetrates the splicing surface of the splicing plate 31. In the embodiment of this application, two notches 4 are provided on one splicing plate 31 to correspond to the four connecting steel bars 12 on the steel plate 11. After the two splicing plates 31 are spliced together, the notches 4 are arranged in communication. After the two splicing plates 31 are spliced together, the anchoring component is located in the notch 4. The offset prevention device further includes a first fixing member for fixing the two splicing plates 31 to the spliced state;

[0046] Refer to Figure 2 and Figure 3, connecting plates 5 are rotatably arranged at both ends of the splicing plate 31 along the height direction of the steel bar framework 2. The connecting plates 5 are rectangular plates, and the rotation axes of the connecting plates 5 are parallel to the plane where the splicing plate 31 is located. The free ends of the connecting plates 5 are used to be fixed on the formwork 20.

[0047] When building the main body of a building, first, the steel bar framework 2 is erected. Subsequently, the embedded part 1 is welded to the steel bar framework 2, and the connecting steel bars 12 are hooked on the main steel bars 21 or stirrups 22. At this time, there is a certain distance between the steel plate 11 and the steel bar framework 2. Then, the formwork 20 is arranged around the steel bar framework 2, and the formwork 20 is fixed by the tie rods; in the above process, after the connecting steel bars 12 are welded to the steel bar framework 2, the splicing plate 31 is sleeved on the connecting steel bars 12, and then the two splicing plates 31 are connected into a whole by the first fixing member; subsequently, the connecting plate 5 is rotated until it abuts against the formwork 20, and the free end of the connecting plate 5 is fixed on the formwork 20 to complete the installation of the embedded part 1.

[0048] During the concrete pouring process, under the action of the fixing plate 3, the anchoring components of the embedded part 1 are connected into a whole, improving the bending resistance of the anchoring components, reducing the possibility that the steel plate 11 deflects in the direction away from the formwork 20, and improving the embedding quality of the embedded part 1; at the same time, under the action of the connecting plate 5, the connecting plate 5 above the splicing plate 31 pulls the splicing plate 31, and the connecting plate 5 below the splicing plate 31 supports the splicing plate 31, thereby reducing the possibility of the splicing plate 31 deflecting; the splicing plate 31 plays a limiting role on the anchoring components, thereby reducing the possibility of the anchoring components bending and deflecting, and thus reducing the possibility of the steel plate 11 deflecting, further improving the embedding quality of the embedded part 1.

[0049] Refer to Figure 3 and Figure 4 , in the embodiment of the present application, an installation plate 6 is hinged to the free end of the connecting plate 5. The installation plate 6 is a rectangular plate, and the rotation axis of the installation plate 6 is parallel to the rotation axis of the connecting plate 5. The installation plate 6 rotates to be parallel to the plane where the formwork 20 is located and abuts against the formwork 20. Nails 7 are arranged on the surface of the installation plate 6 facing away from the formwork 20. The length direction of the nails 7 is perpendicular to the plane where the installation plate 6 is located, and the nails 7 are used to be driven into the formwork 20; after the installation plate 6 is attached to the formwork 20, the nails 7 are driven into the formwork 20 to complete the connection between the connecting plate 5 and the formwork 20, and the operation is simple and convenient; and it is convenient for the later removal of the formwork 20.

[0050] Refer to Figure 3 and Figure 4, in the embodiment of the present application, the first fixing member includes a screw rod 8 rotatably arranged on the splicing surface of the splicing plate 31. A threaded groove 9 for threaded connection of the screw rod 8 is provided on the other splicing plate 31. Further, a connection groove 10 is provided on the splicing plate 31 where the screw rod 8 is located, and the screw rod 8 is threadedly connected in the connection groove 10. Under the action of the connection groove 10, it is convenient to rotate the screw rod 8 into the threaded groove 9.

[0051] Referring to Figure 3 and Figure 4 , the stirrup 22 has an obstructive effect on the rotation of the connecting plate 5. To facilitate the free end of the connecting plate 5 to abut against the formwork 20, connecting shafts 13 are fixedly arranged at both ends of the splicing plate 31 along the height direction of the steel bar framework 2. In the embodiment of the present application, in combination with Figure 5 , an L-shaped rod 14 is provided on the splicing plate 31. The vertical rod of the L-shaped rod 14 is fixedly arranged on the splicing plate 31, and the horizontal rod of the L-shaped rod 14 is parallel to the surface of the splicing plate 31 where the L-shaped rod 14 is located. The connecting shaft 13 is fixedly arranged on the horizontal rod of the L-shaped rod 14. The connecting plate 5 is sleeved on the connecting shaft 13, and a pin 15 is detachably arranged on the connecting shaft 13. The end of the connecting plate 5 abuts against the pin 15. During the splicing process of the splicing plate 31, the connecting plate 5 is removed from the splicing plate 31. After the splicing plate 31 is spliced, the connecting plate 5 is inserted into the connecting shaft 13 again. When the connecting plate 5 is inserted into the connecting shaft 13, the connecting plate 5 obliquely enters the steel bar framework 2, and then the direction of the connecting plate 5 is adjusted so that the connecting plate 5 can abut against the formwork 20 and can be sleeved on the connecting shaft 13. Then the connecting plate 5 is sleeved on the connecting shaft 13, and then the pin 15 is used to limit the connecting plate 5.

[0052] Referring to Figure 3 and Figure 4 , to reduce the possibility of the connecting shaft 13 tilting under the pulling action of the connecting plate 5, the length direction of the pin 15 is parallel to the plane where the splicing plate 31 is located and is arranged facing the splicing plate 31. The pin 15 is rotatably arranged on the connecting shaft 13, and a threaded section is provided on the pin 15. A threaded hole for threaded connection of the threaded section is provided on the splicing plate 31. Under the action of the pin 15, a simple supported support structure is formed for the connecting shaft 13, reducing the possibility of the connecting shaft 13 bending.

[0053] Referring to Figure 3 and Figure 4 , to reduce the possibility of the connecting plate 5 bending under the impact of concrete, reinforcing ribs are provided on the surface of the connecting plate 5 facing away from the steel plate 11, and the length direction of the reinforcing ribs is parallel to the length direction of the connecting plate 5.

[0054] Referring to Figure 3 and Figure 4, To further reduce the possibility that the connecting plate 5 drives the steel plate 11 to deflect away from the formwork 20 under the impact of concrete, a support rod 16 is rotatably arranged on the connecting plate 5 close to the steel plate 11. The rotation axis of the support rod 16 is parallel to the rotation axis of the connecting plate 5. The support rod 16 is a telescopic structure. An abutting ring 17 is arranged at the end of the support rod 16 away from the connecting plate 5. The abutting ring 17 is disc-shaped, and the area of the abutting ring 17 is larger than the cross-sectional area of the support rod 16. The abutting ring 17 is used to abut against the steel plate 11; the support rod 16 includes a sleeve rod 161 hinged on the connecting plate 5 and a sliding rod 162 threadedly connected in the sleeve rod 161. The abutting ring 17 is rotatably arranged at the end of the sliding rod 162. In the embodiment of the present application, both the sleeve rod 161 and the sliding rod 162 are cylindrical.

[0055] Under the action of the support rod 16, when the connecting plate 5 bends, the connecting plate 5 applies a thrust towards the formwork 20 to the support rod 16, thereby pushing the steel plate 11 to abut against the formwork 20, further reducing the possibility of the steel plate 11 deflecting.

[0056] Refer to Figure 3 and Figure 4 , To reduce the possibility that the connecting steel bars 12 approach each other under the impact of concrete, the offset prevention device further includes an abutting block 18. The abutting block 18 is strip-shaped. After the two splicing plates 31 are spliced, the abutting block 18 is used to move into the notch 4 and abut and support the adjacent anchoring components. The surface of the abutting block 18 close to the inner wall of the notch 4 abuts against the inner wall of the notch 4; under the supporting action of the abutting block 18, it plays a limiting role on the connecting steel bars 12, thereby reducing the possibility that the connecting steel bars 12 approach each other.

[0057] Refer to Figure 3 and Figure 4 , To reduce the possibility that the connecting steel bars 12 jump in the notch 4, an arc-shaped groove 19 is concavely arranged on the end face of the abutting block 18 for abutting against the anchoring component. The radian of the arc-shaped groove 19 is greater than π. In the embodiment of the present application, the radian of the arc-shaped groove 19 is π, and the anchoring component is located in the arc-shaped groove 19; the connecting steel bars 12 are clamped in the arc-shaped groove 19, which plays a limiting role on the jumping of the connecting steel bars 12 and reduces the possibility that the connecting steel bars 12 drive the steel plate 11 to deflect.

[0058] The implementation principle of the offset prevention device of a curtain wall embedded part in the embodiment of the present application is:

[0059] When constructing the main building body, first build the steel bar framework 2, then weld the embedded part 1 on the steel bar framework 2, and hang the connecting steel bar 12 on the main steel bar 21 or stirrup 22. At this time, there is a certain distance between the steel plate 11 and the steel bar framework 2. Then, surround the steel bar framework 2 with the formwork 20 and fix the formwork 20 with tie rods; during the above process, after the connecting steel bar 12 is welded to the steel bar framework 2, sleeve the splicing plate 31 on the connecting steel bar 12, and then connect the two splicing plates 31 into a whole through the first fixing piece; subsequently, rotate the connecting plate 5 until it abuts against the formwork 20, and fix the free end of the connecting plate 5 on the formwork 20;

[0060] Then rotate the support rod 16 until it is perpendicular to the plane of the steel plate 11, and then rotate the sliding rod 162 to drive the abutting ring 17 to slide and abut against the steel plate 11 to complete the installation of the embedded part 1; subsequently, pour concrete into the space surrounded by the formwork 20.

[0061] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
