Description

Adjustable standardized punching tool

Technical Field

The utility model relates to the field of prefabricated parts, in particular to an adjustable standardized punching tool.

Background

Fabricated building is a major trend in the development of the building industry today. The assembly type building mainly adopts integrated building design and construction, so that manpower resources and building materials are greatly saved; the operations of plastering, building walls and the like by constructors on site are reduced, the influence of weather is small, and the construction progress is greatly improved; the emission of building rubbish and harmful gas is reduced, the air conditioner is warm in winter and cool in summer, the temperature of the heater can be reduced in winter, and heating cost and energy consumption are saved for users. The structure is formed by connecting precast concrete members or components through reinforcing steel bars, connectors or prestressing and casting concrete in situ to form an integral structure.

According to the mature design and construction method in the industry at present, the horizontal component adopts a superposed component, the vertical component adopts cast-in-place, and the structural system is regarded as an integral structural system, so that the seismic requirement can be met. The method mainly comprises the following steps: composite slabs, composite beams, prefabricated stairs, prefabricated air-conditioning plates, prefabricated cladding slabs and the like. The composite beam is used as a horizontal component widely used in an assembly type building and is applied to various engineering entities. Due to the numerous horizontal arrangement of electromechanical pipelines in a building, the problem of the need to reserve horizontal perforations in precast beams for later pipeline perforation is inevitably involved. In addition, the use of the fabricated formwork is encouraged in the construction technology nowadays, namely, a perforation channel or an embedded sleeve needs to be reserved in a prefabricated part, so that the arrangement of a follow-up formwork split screw is facilitated.

Therefore, the problem of the reserved holes in the production link of the prefabricated parts is solved, and the problem that each prefabricated part factory needs to be considered emphatically is solved. In order to achieve the process standards of standardization, modularization and light weight, the production cost of the prefabricated part needs to be considered, and cost reduction and efficiency improvement are achieved for enterprises.

The prior art solves the problem that the pre-buried holes in the superposed beam mainly adopt two modes: the first method is to pre-embed a steel bar, select the steel bar with the diameter required by the drawing, pour concrete on a side die of the die, and pull out the steel bar to form a hole when the laminated beam is demoulded, and the method needs to wait for the final setting and forming of the concrete before pulling out the steel bar, otherwise, the hole is easy to collapse, but after the final setting of the concrete, the hole is collided and deformed, the friction force on the surface of the concrete is increased, the steel plate is difficult to pull out, the hole is easy to damage when being forcibly pulled out, and the slurry leakage is serious in the production process, and the quality of the formed hole is poor; the second is pre-buried PVC pipe, the PVC pipe of the required diameter size of drawing is selected, with the PVC pipe box in the rod iron, install the rod iron on the mould side forms again, water the concrete again, when treating the drawing of patterns, only need extract the rod iron, the PVC pipe is reserved in the concrete, although the problem that the rod iron and concrete bond has been solved in this scheme, but need dispose the different rod iron and the packing ring of size according to the PVC pipe of different pipe diameters, and an item often has multiple pipe diameters, need to join in marriage the accessory of multiple specification, and because the rod iron diameter needs to be less than the PVC pipe, because the reason of vibrating in the production, the PVC pipe is easy off normal.
