Description

Technical Field

[0001] This utility model relates to the field of suspended formwork technology, specifically a suspended formwork structure for PC composite plate joints that does not require support bolts. Background Technology

[0002] In prefabricated building construction, formwork is required for the post-cast concrete at the joints of PC composite slabs to ensure molding quality. Traditional methods often use steel pipes to support the formwork, which not only occupies the lower-level working space and interferes with cross-construction, but also has poor support stability, easily causing grout leakage and formwork bulging, resulting in unevenness of the joint pouring layer and requiring additional manual grinding and repair. Some existing suspended formwork uses bolt-rod suspension without support. This suspension structure requires pre-embedded bolts, then a support plate is connected to the bolts, and finally, a flat formwork is placed on the support plate. Finally, the bolts are rotated to seal the joint and prevent material leakage during pouring. However, the existing suspension structure can only hold flat formwork. If the user needs to increase the pouring depth at the joint, this suspension structure cannot meet the requirements. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a bolt-free suspension structure for the joints of PC composite panels, thereby solving the problems mentioned in the background art, such as the limited applicability of traditional suspension structures, their inability to cope with special situations where the casting depth at the joints is deep, and the lack of adjustability of the suspension structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a boltless support rod suspension formwork structure for the joint of a PC composite panel, comprising two precast panels, with a joint between the two precast panels and a suspension formwork assembly for constructing the joint. The suspension formwork assembly includes a first connector, a second connector, and an adapter component. The first connector and the second connector are respectively connected to one precast panel via a suspension rod. The upper end of the suspension rod has a baffle for abutting against the upper surface of the precast panel. There is a notch between the first connector and the second connector for placing the adapter component. The adapter component is detachably connected to the first connector and the second connector. The side of the adapter component facing the precast panel can form a seal with both precast panels respectively, and the side facing the first connector and the second connector can abut against the first connector and the second connector respectively.

[0005] As a further improvement of this utility model, a slot is provided on the upper end face of both the first connector and the second connector, and a plug is provided on the adapter component at the corresponding slot position, and the plug can be inserted and engaged with the slot.

[0006] As a further improvement of this utility model, the adapter component is a sealing plate. The side wall of the sealing plate facing the precast slab can form a seal with both precast slabs respectively, and a receiving groove for casting material is formed between the two precast slabs and the sealing plate.

[0007] As a further improvement of this utility model, the adapter component is a sealing groove plate, the sealing groove plate has a groove, the groove has an opening facing the precast slab, the groove plate is provided with a side ear for each of the two precast slabs, the upper end face of the side ear can form a seal with the precast slab on the corresponding side, the groove can be used to accommodate casting material, and a long groove for casting material is formed between the two precast slabs and the sealing groove plate.

[0008] As a further improvement of this utility model, a gasket is provided on the opposite side wall of the first connector and the second connector, and the gasket can abut against the adapter component.

[0009] Compared with the prior art, this utility model provides a bolt-free suspended formwork structure for the joints of PC composite panels, which has the following advantages: the connectors are suspended from the precast slab by the suspension rod with baffles, eliminating the need for steel pipe support, avoiding the occupation of lower space, and not interfering with cross-construction; the adapter and connectors are detachably connected, and the suspension rods and connectors do not need to be cured in concrete, allowing for complete recycling and reuse after construction, reducing material waste and costs; the adapter and precast slab form a seal, preventing grout leakage; the structure does not require multiple reinforcement and adjustments during assembly, making installation and disassembly convenient, shortening working hours, and reducing labor costs.

[0012] As shown in the figure, to achieve the above-mentioned objective, this utility model provides a boltless support rod suspension formwork structure for the splice 2 of a PC composite panel, including two precast panels 1, with a splice 2 between the two precast panels 1 and a suspension formwork assembly 3 for constructing the splice 2. The suspension formwork assembly 3 includes a first connector 31, a second connector 32, and an adapter component 33. The first connector 31 and the second connector 32 are respectively connected to one precast panel 1 via a suspension rod 34. The upper end of the suspension rod 34 has a baffle 35 for abutting against the upper surface of the precast panel 1. There is a notch 4 between the first connector 31 and the second connector 32 for placing the adapter component 33. The adapter component 33 is detachably connected to the first connector 31 and the second connector 32 respectively. The side of the adapter component 33 facing the precast panel 1 can form a seal with the two precast panels 1 respectively, and the side facing the first connector 31 and the second connector 32 can abut against the first connector 31 and the second connector 32 respectively.

[0013] In this solution, a rectangular notch 4 is formed between the opposite sides of the first connector 31 and the second connector 32. During installation, the hanger 34 is first passed through the pre-drilled hole of the connector and fixed, so that the connector is partially suspended below the joint 2. Then, the adapter 33 is embedded into the notch 4 of the two connectors or placed on the two connectors to cover the notch 4. The detachable connection is achieved through a snap-fit ​​or plug-in structure. The side of the adapter 33 facing the precast slab 1 has an elastic edge that fits tightly against the side wall of the precast slab 1 to form a seal. This seal is to prevent leakage of the pouring material during construction. The side facing the connector is a rigid plane that directly abuts against the side wall of the notch 4, forming an integral load-bearing structure that can withstand the pouring pressure without additional support. In this solution, those skilled in the art can set different adapters 33 on the connectors according to the actual construction needs. The adapter 33 is easy to assemble and disassemble with the first connector 31 and the second connector 32 to meet different construction needs.

[0014] As an improved specific implementation, a slot 36 is provided on the upper end surface of both the first connector 31 and the second connector 32, and a plug 37 is provided on the adapter 33 corresponding to the position of the slot 36, and the plug 37 can be inserted and cooperated with the slot 36.

[0015] In this solution, slots 36 are provided on the upper surfaces of the first connector 31 and the second connector 32. The slots 36 can be rectangular. After the first and second connectors 32 are suspended in place by the hanger 34, the plugs 37 at both ends of the adapter 33 are aligned with the slots 36 of the connector and inserted vertically. When disassembling, the adapter 33 only needs to be pulled upward to disengage the plugs 37 from the slots 36, thus achieving quick separation and solving the problem of cumbersome disassembly of traditional connectors.

[0016] As an improved specific implementation, the adapter 33 is a sealing plate 331. The side wall of the sealing plate 331 facing the precast slab 1 can form a seal with both precast slabs 1 respectively. A receiving groove 332 for casting material is formed between the two precast slabs 1 and the sealing plate 331.

[0017] In implementation, the adapter component 33 is a sealing plate 331, made of aluminum alloy or high-strength engineering plastic. The length of the sealing plate 331 matches the distance between the two precast slabs 1, and its width is greater than the width of the joint 2. Its two side walls facing the precast slab 1 can be sealed in two ways: one is by machining a smooth surface on the side walls, directly fitting them to the side of the precast slab 1; the other is by attaching rubber sealing strips to the side walls, enhancing the sealing effect through compression deformation. The inserts 37 at both ends of the sealing plate 331 are aligned with the slots 36 of the first and second connecting parts 32 and inserted until the upper surface of the plate is flush with the bottom surface of the precast slab 1. At this point, those skilled in the art can adjust the hanger 34 to ensure that the two side walls of the sealing plate 331 are in close contact with the two precast slabs 1, and the top of the plate and the bottom surface of the precast slab 1 enclose a rectangular receiving groove 332. During pouring, the receiving groove 332 receives the concrete material, and the sealing plate 331 remains stable under the limiting effect of the inserts 37 and slots 36 and the support of the connecting parts, preventing deformation and grout leakage.

[0018] As an improved specific embodiment, the adapter 33 is a sealing groove plate 333. The sealing groove plate 333 has a groove with an opening facing the precast slab 1. The groove plate is provided with a side ear 334 for each of the two precast slabs 1. The upper end face of the side ear 334 can form a seal with the precast slab 1 on the corresponding side. The groove can be used to accommodate the casting material. A long groove 335 for casting material is formed between the two precast slabs 1 and the sealing groove plate 333.

[0019] In implementation, the adapter component 33 uses a sealing groove plate 333, with a U-shaped groove structure and the groove opening facing upwards. The insert 37 of the sealing groove plate 333 is inserted into the slots 36 of the first and second connectors 32, so that the sealing gasket on the upper end of the side ear 334 is tightly fitted with the bottom surface of the precast slab 1 to form a seal. The U-shaped groove of the groove plate is located directly below the joint 2, forming a long groove 335 structure with the two precast slabs 1. The inside of the groove is used to accommodate the casting material. The side ear 334 cooperates with the slot 36 of the connector to achieve vertical positioning. The side wall of the groove plate abuts against the connector to enhance rigidity, which can withstand greater casting pressure and is not easily deformed.

[0020] As an improved specific implementation, a gasket 5 is provided on the opposite side wall of the first connector 31 and the second connector 32, and the gasket 5 can abut against the adapter 33.

[0021] When this solution is implemented, if the adapter component 33 is a sealing groove plate 333, the gasket 5 abuts against the outer peripheral wall of the groove plate and can form an interference fit to further improve the sealing performance and structural stability.

[0022] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
