Technical Field

[0001] The utility model relates to the technical field of hanging mold fixing, in particular to a detachable three-section hanging mold fixing device. Background Art

[0002] With the continuous development of the construction market, prefabricated projects have grown as a "new force" in engineering construction. In the construction process of prefabricated structures, the construction of prefabricated composite panel components occupies a very important position in the construction of residential buildings, so the hanging formwork construction of composite panel strips has become an inevitable link.

[0003] In engineering construction, the composite slab strips are used to construct the formwork support system of the concrete structure, while the formwork screws are used to support and composite the slab strips to ensure the stability and safety of the formwork support system.

[0004] The traditional non-detachable formwork screw rod cannot be disassembled after the pouring and hardening is completed, and the excess part can only be cut off. Since it cannot be disassembled in sections, more manpower and time are required for cutting, which increases labor costs and affects the progress of the project. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a detachable three-section hanging mold fixing device, which aims to improve the problem that the traditional non-detachable hanging mold screw cannot be disassembled in sections, requires more manpower and time to cut, increases labor costs and affects project progress.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a detachable three-section hanging formwork fixing device, including a supporting cross bar and a steel bar cross beam, the middle part of the bottom end of the supporting cross bar is fixedly connected with a connecting block, the bottom end of the connecting block is fixedly connected with a bolt, the bottom end of the outer wall of the bolt is threadedly connected with a conical nut, the bottom end of the inner wall of the conical nut is threadedly connected with a matching screw rod, and the middle and lower part of the outer wall of the matching screw rod is threadedly connected with a mountain-shaped buckle.

[0007] Through the above technical solution: compared with the traditional non-detachable screw, the cutting construction link is reduced, the construction efficiency of the plate and strip formwork is guaranteed, and there are many parts of the plate and strip hanging formwork that can be recycled and reused, thereby saving the construction cost of the plate and strip formwork.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the outer wall of the matching screw rod is threadedly connected with a fixing buckle.

[0010] Through the above technical solution: the fixing buckle can perform secondary fixation on the mountain-shaped buckle, which is equivalent to a double insurance mechanism, thereby improving the overall stability.

[0011] As a further description of the above technical solution:

[0012] The matching screw rod is penetrated by a prefabricated plate seam hanging mold.

[0013] Through the above technical solution: the force-bearing area can be evenly distributed on the bottom wall of the prefabricated plate seam hanging formwork while the whole is pulled upward, so that it will not be broken due to excessive force at a certain place.

[0014] As a further description of the above technical solution:

[0015] The left and right ends of the top wall of the prefabricated plate seam hanging formwork are both fixedly connected with superimposed plates.

[0016] Through the above technical solution: the composite slabs can be bonded by hanging the prefabricated slab seam formwork and can be better demoulded after pouring.

[0017] As a further description of the above technical solution:

[0018] The left and right sides of the top wall of the mountain-shaped buckle are both provided with grooves.

[0019] Through the above technical solution: the groove can make it easier for the steel bar beam to fall into the groove during installation, thereby improving the fault tolerance during installation.

[0020] As a further description of the above technical solution:

[0021] The width of the prefabricated plate seam hanging formwork is greater than the distance between the two superimposed plates.

[0022] Through the above technical solution: the contact area between the prefabricated plate seam hanging formwork and the composite plate is increased, making it more stable during pouring.

[0023] As a further description of the above technical solution:

[0024] The length of the steel bar cross beam is greater than the width of the prefabricated plate seam hanging formwork.

[0025] Through the above technical solution: the steel bar cross beam can be better fitted to the bottom wall of the prefabricated plate seam hanging formwork.

[0026] As a further description of the above technical solution:

[0027] The width of the steel bar cross beam is between the distance between the adjacent side and the remote adjacent side of the inner walls of the two grooves.

[0028] Through the above technical solution: the upper and lower sides of the steel beam need to be engaged in the two grooves during installation, so the width of the steel beam should be between the distance between the adjacent side and the distant adjacent side of the inner wall of the two grooves, which can improve the fault tolerance during installation.

[0029] The utility model has the following beneficial effects:

In the utility model, the matching screw rod is penetrated into the reserved hole in the top wall of the prefabricated plate seam hanging formwork, and then the base of the conical nut is connected downward to the top of the outer wall of the matching screw rod, and the mountain-shaped buckle is threadedly connected to the middle and lower part of the matching screw rod. During the connection process, the steel beam is inserted into the groove. Since the supporting cross bar, the connecting block and the bolts are fixedly connected, the supporting cross bar can be rotated to pull the mountain-shaped buckle and the steel beam upward through the threads in the conical nut, and at the same time, the prefabricated plate seam hanging formwork and the composite plate can be firmly locked. Compared with the traditional non-detachable screw rod, the cutting construction link is reduced, the construction efficiency of the plate strip demoulding is guaranteed, and there are many parts of the plate strip hanging formwork, which can be recycled and reused, thereby saving the construction cost of the plate strip supporting formwork.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a detachable three-section hanging formwork fixing device, comprising a supporting cross bar (1) and a steel bar cross beam (8), wherein a connecting block (2) is fixedly connected to the middle of the bottom end of the supporting cross bar (1), a bolt (3) is fixedly connected to the bottom end of the connecting block (2), a conical nut (4) is threadedly connected to the bottom end of the outer wall of the bolt (3), a matching screw rod (5) is threadedly connected to the bottom end of the inner wall of the conical nut (4), and a mountain-shaped buckle (6) is threadedly connected to the middle and lower part of the outer wall of the matching screw rod (5);

[0038] Specifically, during installation, first penetrate the matching screw rod 5 into the reserved hole on the top wall of the prefabricated plate seam hanging formwork 10, and then turn the base of the conical nut 4 downward and the cone head upward, and thread it on the top of the outer wall of the matching screw rod 5, so that the base surface of the conical nut 4 fits on the top wall of the prefabricated plate seam hanging formwork 10, and the mountain-shaped buckle 6 is threadedly connected to the middle and lower part of the matching screw rod 5. During the connection process, the steel bar cross beam 8 is inserted into the groove 11 until the steel bar cross beam 8 is roughly fitted with the bottom end of the prefabricated plate seam hanging formwork 10. The left and right ends of the top wall of the reinforcement beam 8 serve as the fastening parts of the prefabricated plate seam hanging formwork 10, so the mountain-shaped buckle 6 and the reinforcement beam need to be in a horizontal position. At this time, a certain gap is left between the reinforcement beam 8 and the prefabricated plate seam hanging formwork 10. Since the support cross bar 1, the connecting block 2 and the bolt 3 are fixedly connected, the bolt 3 is threadedly connected to the top of the inner wall of the conical nut 4. By rotating the support cross bar, the mountain-shaped buckle 6 and the reinforcement beam 8 can be pulled upward through the thread in the conical nut 4, and at the same time, the prefabricated plate seam hanging formwork 10 and the composite plate 9 can be firmly locked.

[0039] Reference Figure 1 and Figure 2 The bottom end of the outer wall of the matching screw rod (5) is threadedly connected with a fixing buckle (7); the matching screw rod (5) is penetrated by a prefabricated plate seam hanging mold (10); the left and right ends of the top wall of the prefabricated plate seam hanging mold (10) are fixedly connected with a superimposed plate (9); the left and right sides of the top wall of the mountain-shaped buckle (6) are provided with grooves (11);

[0040] Specifically, the fixing buckle 7 is used to perform a secondary locking on the mountain-shaped locking buckle 6 after the mountain-shaped buckle 6 is locked upward, thus playing a double insurance role. The matching screw rod (5) penetrates the middle of the prefabricated plate seam hanging mold (10), which can evenly spread the tension to the surrounding areas, increase the force-bearing area, and prevent rupture due to excessive force at a certain place. The groove (11) provided on the top wall of the mountain-shaped buckle (6) is used to fix the steel bar beam (8), and a certain redundant distance is left to facilitate installation.

[0041] Reference Figure 2, the width of the prefabricated plate seam hanging formwork (10) is greater than the distance between the two superimposed plates (9); the length of the steel bar cross beam (8) is greater than the width of the prefabricated plate seam hanging formwork (10); the width of the steel bar cross beam (8) is between the distance between the adjacent side and the remote adjacent side of the inner walls of the two grooves (11);

[0042] Specifically, since the prefabricated plate seam hanging formwork 10 needs to be fixed upwardly on the bottom wall of the composite plate 9, when manufacturing the prefabricated plate seam hanging formwork 10, the width should be greater than the distance between the two composite plates 9. Similarly, when manufacturing the steel bar cross beam (8), the length of the steel bar cross beam (8) should be greater than the width of the prefabricated plate seam hanging formwork (10). When manufacturing the steel bar cross beam (8), the distance between the two grooves (11) needs to be considered. The upper and lower sides of the steel bar cross beam (8) need to be engaged in the two grooves (11) during installation. Therefore, the width of the steel bar cross beam (8) should be between the distance between the adjacent side and the distant adjacent side of the inner wall of the two grooves (11).

[0043] Working principle: During installation, first penetrate the matching screw rod 5 into the reserved hole on the top wall of the prefabricated plate seam hanging formwork 10, and then turn the base of the conical nut 4 downward and the cone head upward, and thread it on the top of the outer wall of the matching screw rod 5, so that the base surface of the conical nut 4 fits on the top wall of the prefabricated plate seam hanging formwork 10, and thread the mountain-shaped buckle 6 to the middle and lower part of the matching screw rod 5. During the connection process, insert the steel bar cross beam 8 into the groove 11 until the steel bar cross beam 8 is roughly fitted with the bottom end of the prefabricated plate seam hanging formwork 10. Since the left and right ends of the top wall of the steel bar cross beam 8 are needed as the fastening parts of the prefabricated plate seam hanging formwork 10, the mountain-shaped buckle 6 and the steel bar cross beam 8 are fastened to the top wall of the prefabricated plate seam hanging formwork 10. The reinforcement beam needs to be in a horizontal position. At this time, there is a certain gap between the reinforcement beam 8 and the prefabricated plate seam hanging formwork 10. Since the support cross bar 1, the connecting block 2 and the bolt 3 are fixedly connected, the bolt 3 is threadedly connected to the top of the inner wall of the conical nut 4. By rotating the support cross bar, the mountain-shaped buckle 6 and the reinforcement beam 8 can be pulled upward through the thread in the conical nut 4. At the same time, the prefabricated plate seam hanging formwork 10 and the composite plate 9 can be firmly locked. Compared with the traditional non-detachable screw, the cutting construction link is reduced, the construction efficiency of the plate strip demoulding is guaranteed, and there are many parts of the plate strip hanging formwork, which can be recycled and reused, thereby saving the construction cost of the plate strip support formwork.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
