Description

Technical Field

[0001] This utility model belongs to the field of concrete composite slab manufacturing technology, specifically relating to a hole forming device for composite slabs. Background Technology

[0002] Prefabricated housing construction uses prefabricated components for installation and assembly, dry construction, which saves manpower, makes the construction site clean and beautiful, and the final performance is consistent with that of ordinary cast-in-place construction.

[0003] For the construction of prefabricated components used in prefabricated houses, the on-site workers adopt the following construction steps: First, tie the reinforcing steel bars of the external wall beams; second, lay the prefabricated slabs in the composite slab; finally, lay the slab reinforcement bars at the top of the composite slab, and pour the concrete after the slab reinforcement bars are laid.

[0004] However, in this construction step, the binding of the beam reinforcement is completed first. During the subsequent hoisting of the composite slab, the slab reinforcement is prone to interfering with the beam reinforcement, preventing it from extending into the beam as required by specifications. Furthermore, the existing reinforcement uses Grade III steel, which has high strength and rigidity; even with a diameter of only 8mm, it is difficult to bend and insert it into the beam.

[0005] In existing technologies, a non-reinforced composite slab has been developed to address the aforementioned issues. This involves eliminating exposed slab reinforcement during construction and instead using diagonally inserted reinforcement channels. By adding slab reinforcement into each diagonally inserted reinforcement channel after the composite slab is hoisted on-site, interference between the slab reinforcement and the beam reinforcement is avoided.

[0006] Traditional production methods require separate tooling for fixing and positioning pre-drilled holes, performed sequentially. However, the number of pre-drilled holes on each unreinforced composite slab is excessive, and each hole needs precise positioning according to spacing requirements. If PVC pipes (used for pre-drilled holes, removed after concrete hardening) are tied to positioning rods with wire each time, it would consume a significant amount of manpower and resources. Furthermore, the tying wires need to be cleaned during the later removal of the PVC pipes, greatly increasing time and labor costs. Utility Model Content

[0007] To overcome the shortcomings of the existing technology, this utility model provides a hole forming device for composite plates, which solves the technical problems of low positioning and fixing efficiency of PVC pipes used to form holes on composite plates and difficulty in subsequent disassembly.

[0008] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0009] A hole-forming device for composite plates includes a limiting frame, a supporting beam, and multiple hole-forming components. The limiting frame has multiple sequentially arranged limiting grooves. The tail end of each hole-forming component passes through a corresponding limiting groove.

[0010] The supporting beam is fixed to the truss reinforcement, and the length direction of the supporting beam is parallel to the arrangement direction of each duct forming component. The outer end of each duct forming component is fixedly connected to the supporting beam.

[0011] Furthermore, the supporting beam is fixed with multiple sequentially arranged connectors. Each connector has a clearance through hole that mates with the channel forming component. The outer end of each channel forming component passes through the clearance through hole on the corresponding connector.

[0012] Furthermore, the connector uses a hexagonal nut. The hexagonal nut is tied to the support beam with wire.

[0013] Furthermore, each of the aforementioned limiting grooves is fitted with a rubber plug.

[0014] Furthermore, the supporting crossbeam is made of threaded steel. The duct forming component is made of PVC pipe.

[0015] Furthermore, the distance between two adjacent limiting grooves on the limiting frame is 200mm.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention limits the position of the duct forming component by creating multiple sequentially arranged limiting grooves on a limiting frame. Simultaneously, by incorporating a supporting beam and a connector with clearance through holes, the duct forming component can be rapidly formed via a push-pull mechanism. This allows for priority installation of the composite slab during subsequent installation, enabling the beam reinforcement to be inserted into the beam body through the formed ducts. This avoids interference between exposed beam reinforcement and the reinforcement on the beam body during composite slab installation, which could prevent installation. Furthermore, it significantly improves the efficiency and accuracy of loading and unloading the duct forming component, saving considerable manpower and resources. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a channel forming device for laminated slabs can form multiple inclined channels in the laminated slab during the casting process. The specific structure of the channel forming device is as follows. Figure 1 and 2 As shown, the assembly includes a limiting frame 1, a supporting beam 2, and multiple perforated components 3. The limiting frame 1 is positioned perpendicular to the arrangement direction of the truss reinforcement on the composite slab. Multiple sequentially arranged limiting grooves 4 are formed on the limiting frame 1 to define the position of each perforated component 3. The tail end of each perforated component 3 passes through its corresponding limiting groove 4 and rests on a mold platform for placing the limiting frame 1. The supporting beam 2 is fixed to the truss reinforcement, and its length direction is parallel to the arrangement direction of the perforated components 3. The outer end of each perforated component 3 is fixedly connected to the supporting beam 2.

[0024] Specifically, such as Figure 2 As shown, the supporting beam 2 is fixed with multiple connectors 5 arranged in sequence. Each connector 5 has a clearance through hole 6 that mates with the channel forming part 3. The outer end of each channel forming part 3 passes through the clearance through hole 6 on the corresponding connector 5, thereby supporting the outer end of the channel forming part 3.

[0025] In this embodiment, the connector 5 is a hexagonal nut. The hexagonal nut is tied to the support beam 2 with wire, thereby ensuring that the hexagonal nut can rotate and adjust around the axis of the support beam 2, and ensuring that the outer end of the channel forming part 3 can smoothly pass through the clearance through hole 6 on the hexagonal nut.

[0026] In this embodiment, a rubber plug (not shown in the figure) is inserted into each limiting groove 4. The rubber plug is inserted after the channel forming part 3 extends into the corresponding limiting groove 4 to seal the limiting groove 4 and prevent concrete slurry from leaking from the opening of the limiting groove 4 during the pouring process.

[0027] Furthermore, the supporting beam 2 is made of threaded steel. The duct forming component 3 is made of PVC pipe.

[0028] In addition, in this embodiment, the distance between two adjacent limiting grooves 4 on the limiting frame 1 is 200mm.

[0029] The working principle of this utility model is as follows:

[0030] First, fix the limiting frame 1 to the mold platform along a direction perpendicular to the truss reinforcement. Simultaneously, tie and fix the supporting beam 2 to the truss reinforcement. Next, place each channel forming component 3 at an angle within its respective limiting groove 4 on the limiting frame 1, and pass the outer end of each channel forming component 3 through the clearance through hole 6 on the corresponding connector 5. By moving the position of the supporting beam 2 on the truss reinforcement, the tilt angle of the channel forming component 3 can be finely adjusted. After adjusting the channel forming component 3, rubber plugs can be inserted into each limiting groove 4 to seal the groove opening.

[0031] Concrete grout is poured in to form the required composite slab. During the pouring process, the supporting beam 2 remains exposed. When the concrete grout has initially set, the forming components 3 of each channel are removed. The original positions of the forming components 3 are now occupied by the required inclined channels.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
