Abstract
The utility model discloses a secondary pouring form board constructing structure for a small opening of a concrete structure floor slab. The secondary pouring form board constructing structure comprises a bottom plugging form board supporting the bottom of the opening, a group of holes are formed in the middle of the bottom plugging form board, the number of the holes is two, a through long reinforcing rebar is fixed on the bottom wall of the bottom plugging form board between the two holes, a lead wire of an outer plastic sleeve penetrates through the two holes and bypasses the reinforcing rebar to be firmly bound to a rebar support supporting a floor slab concrete structure. The secondary pouring form board constructing structure has the advantages of being simple to manufacture, convenient to operate, high in strength, quick and practical and capable of being used repeatedly.
Description
Technical field
The utility model relates to template construction structure, and the utility model relates in particular to a kind of slab in concrete structure duck eye mouth secondary formwork for placing constructing structure.
Background technology
In work progress, on structure floor, need to stay to establish as some small-sized holes such as measured holes, before flooring surface construction, need these holes to seal, the mode that job site adopts hole to divide into rod support formwork is conventionally carried out concrete second pouring, supporting the length of rod need to adjust according to floor height, and the out-of-flatness defect that easily generation causes concrete lower surface to occur because support top is insecure, affect impression quality, after-treatment is also more difficult.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of simple, quick and practical slab in concrete structure duck eye mouth secondary formwork for placing constructing structure is provided.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of slab in concrete structure duck eye mouth secondary formwork for placing constructing structure of the present utility model, it comprises a bottom stopend that is located at bottom, hole, have one group of hole in the centre of described bottom stopend, one group of hole comprises two holes, on the diapire of the bottom stopend between two holes, be fixed with an elongated stiffener, the galvanized wire of an overcoat plastic bushing is through two holes and walk around stiffener and be supported on the structural Steel bar rack colligation of floorslab concrete firm.
The beneficial effects of the utility model are: make simply, easy to operate, intensity is high, quick, practical, can have enough to meet the need use.
Brief description of the drawings
Accompanying drawing is the structural representation of a kind of slab in concrete structure duck eye mouth secondary formwork for placing constructing structure of the present utility model.
Detailed description of the invention
A kind of slab in concrete structure duck eye mouth secondary formwork for placing constructing structure of the present utility model as shown in drawings, it comprises a bottom stopend 5 that is located at bottom, hole, have one group of hole 6 in the centre of described bottom stopend, one group of hole comprises two holes, the galvanized wire 2 that is fixed with 7, overcoat plastic bushings 3 of an elongated stiffener on the diapire of the bottom stopend between two holes is through two holes and walk around stiffener 7 and to be supported on Steel bar rack 1 colligation in floorslab concrete structure 4 firm.
Bottom stopend 5 carries out concreting installing firmly after qualified by inspection, and plastic bushing 3 is embedded in secondary concreting thickness range, and can ensure form removal time, inner galvanized wire 2 is extracted out smoothly.
