Abstract
The utility model relates to a plastic formwork used for cast-in-place in construction, which provides a construction formwork which can be used repeatedly and is used for casting concrete components in place. The plastic formwork is in the structure of a plate structure formed through extrusion, a plurality of reinforcement ribbed slabs are arranged in the cavity of the plate, through cavities are formed among the ribbed slabs, simultaneously tenons can also be arranged at the left connector end of the plastic formwork, and tusk grooves corresponding to the tenons are arranged at the right connector end. The plastic formwork has the advantages that the structure is simple, the assembly and the disassembly are convenient, the rigidity is good, the stability is high, the bearing capacity is strong, no grout leakage at the joints of the formworks can be guaranteed, the plastic formwork can be reused repeatedly, and the construction cost can be greatly reduced.
Description
Affiliated technical field
The utility model relates to the utensil that a kind of building operations is used, and specifically is the building operations template of heavily using of answering that is used for the cast-in-situ concrete member.
Background technology
Concrete component is one of modal building material product, and construction formwork is the requisite utensil of fluid concrete member.Use maximum templates that steel form, wooden form, Bamboo Formwork are arranged in the existing building engineering.Steel form intensity height wherein, fineness is good, and abrasion resistance is strong, but its cost of production height also needs a large amount of steel fasteners during installation, and operation is heavy, and press setter people's labour intensity is big; Though wooden form, Bamboo Formwork cost are lower, fineness is all right, insufficient strength, and corrosion resistant is acidproof, anti-wear performance is poor, and application life is short.So occurred a kind of plastic formwork in recent years again, its intensity, fineness are better, reusable, and cost of production is also reasonable.But its structure is the solid slabbed construction of extrusion modling, and this not only makes the materials cost raise, and its planeness and stiffness are descended to some extent; Existing in addition plastic formwork docks for flat mouthful with the employing that is connected between the plastic formwork, can make form joint place spillage, causes the quality of concrete members of being poured into a mould to descend.Therefore be necessary existing plastic formwork is improved and perfect.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of not only good rigidity, stability by force, have enough supporting capacitys, and simple in structure, mounting or dismounting convenience, non-caked with concrete, the demoulding is easy, can guarantee not spillage of form joint place, cost of production is low simultaneously, reusable plastic formwork.
The purpose of this utility model realizes by following technical measures: the plastic formwork of the cast-in-place usefulness of this building operations is the plate structure of extrusion modling.The intraperitoneal of its plate is provided with deep floor, forms penetrating cavity between the floor.Also be provided with the tenon head in the left side of plastic formwork interface end simultaneously, the right side interface end is provided with sunk coak correspondingly.
The geometry of tenon head described in the utility model and sunk coak can be rectangle tenon head and rectangle sunk coak; Also can be swallow-tail form tenon head and swallow-tail form sunk coak; Also can be circular arc tenon head and circular arc sunk coak.
The beneficial effects of the utility model are that this plastic formwork is simple in structure, mounting or dismounting are convenient, good rigidity, and stability is high, supporting capacity is strong, is convenient to laid reinforcement binding, installation, also is convenient to concretely build, maintenance, can guarantee not spillage of form joint place.This template has very strong versatility in addition, can be repeatedly used, and can reduce the building operations cost significantly.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the structure chart of the utility model when interconnecting.
Fig. 3 is a use working drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: this plastic formwork is that to select resin, fine particle calcium carbonate, haloflex, modifier for use be the sheet material of material and in accordance with regulations proportioning extrusion modling.The shape of its sheet material is that intraperitoneal is provided with deep floor 1, forms penetrating cavity 2 between the floor 1.Simultaneously be provided with the tenon head 3 that its shape is circular arc, and be provided with the sunk coak 4 that its shape is circular arc in the right side of this plastic formwork interface end in the left side of this plastic formwork interface end.
This plastic formwork is the needs according to cast-in-place scene when using, the tenon head of each plastic formwork interface end inserted with the sunk coak of every another plastic formwork interface end be connected, form a smooth plane, and make their connection length reach desired concreting length.And the following available pillar of the plastic formwork that is connected supports them.Can reduce the time of adjusting template like this, improve efficiency of construction, can also avoid the seam crossing spillage simultaneously, guarantee whole pouring quality.
Claims (2)
