Abstract

The utility model relates to a double cone floorslab reserved-hole die, wherein an upper big cone and a lower small cone are connected with each other to form a step-shaped main body; a cover plate is arranged at an upper opening of the big cone; round holes through which a screw can penetrate are arranged on the bottom surface of the big cone and the bottom surface of the small cone; and the centers of the two round holes are on a same axis. The die is placed on a floor die plate; and after the centering, the fixing and embedding and the concreting, a reserved hole of a water drainage riser of a floorslab is in a double step-shaped cone shape with the upper part being big and the lower part being small, thereby being beneficial for seepage prevention treatment surrounding the hole of the riser. The double cone floorslab reserved-hole die has the characteristics that the manufacturing is simple, the positioning is accurate, the installation and the disassembling are convenient, the die can be used repeatedly, the seepage prevention performance is improved, the common quality problem can be reduced, and the rework and repair quality cost can be lowered.

Description

Compound conical floor is reserved the hole mould

Technical field

The utility model relates to a kind of compound conical floor reservation hole mould in the construction work, is mainly used in the moulding that washroom, kitchen, balcony etc. have the reservation hole at soil stack position in the cast-in-situ floor between boiled water room.

Background technology

In the existing building engineering construction; Need when watering floor, to reserve the hole, be used to pass through soil stacks such as floor drain, water closet, washbowl, bathtub, washing machine, at present; During cast-in-situ floor; The common method that adopts of handing-over position hole to be provided mouth mainly contains: (1) UPVC sleeve method of directly burring, this method only are applicable to that soil stack is designed to the common engineering of UPVC material, is not selected to the highrise building of cast iron soil stack; Though and construction molding, convenient and swift, labor and material saving, the UPVC sleeve often causes the do over again bad phenomenon of rectification, increase cost of floor gap drainage system pipe difficult installation up and down because of locating inaccurate or laterally out-of-level, vertical out of plumb.(2) adopt single tubaeform reservation hole mould, this mould is employed in mold periphery usually fixedly the time and adds the nail wire nail and be aided with the method for pricking a drawknot, is subjected to displacement often even the phenomenon of overturning in concreting; On the other hand; The mould outer wall becomes single inclination angle side, and the upper big and bottom samll shape hole to be provided oral-lateral limit of institute's moulding also is single inclination angle side, and its seepage diversion path is less relatively; During like soil stack periphery concrete filling-up hole leakiness, be prone to cause the pipe hole that the seepage phenomenon takes place.

Summary of the invention

The purpose of the utility model provides a kind of compound conical floor and reserves the hole mould; Process the reservation hole at cast-in-situ floor soil stack position with it; Be convenient to riser hole periphery and carry out the antiseepage processing, avoid the floor infiltration, thereby overcome the deficiency that existing floor is reserved the hole.

This mould is linked to be the main body of notch cuttype by the small cone body of the big cone on top and bottom, the big cone cover plate that is provided with suitable for reading, and the bottom surface of big cone has the circular hole that supplies interspersed screw with the bottom surface of small cone body, and the center of two circular holes is on same axis.

The upper inside wall of said big cone is provided with at least three projections shelving cover plate.

The outer wall upper periphery of said big cone is provided with and is used to connect few three hooks of pricking silk.

Said big cone is equipped with handle.

Said cover plate is provided with carries ear.

Reserve hole by the formed in mould floor soil stack of basis and present greatly, descend little staged pyramid type hole; After in this hole, soil stack being installed; Can adopt pea gravel concreten that the reservation hole of soil stack neighboring is tamped; It is tight to make standpipe periphery pea gravel concreten hang the hole shutoff, and has increased the diversion path of seepage, and the antiseepage that more helps soil stack periphery between boiled water room is handled; Guarantee to manage the antiseepage of hole periphery, reach and improve barrier performance, reduce common quality defect and do over again and reprocess the effect of quality cost.The utility model is simple and reasonable, has the characteristics of tool-typed formwork, can carry out the batch production typing according to the different size model and produce in batches; Also but field machining is made; Once investment, long-term turnover are used, and are easy to positioning control, fixed when lay at the scene, are easy to the demoulding.

Description of drawings

Fig. 1 is the positive view of the utility model.

Fig. 2 is the positive vertical view of the utility model.

Fig. 3 is the user mode sketch map of the utility model.

Among the figure, the big cone of 1-, the 2-small cone body, the 3-circular hole, the 4-cover plate, 5-carries ear, the 6-projection, the 7-hook, 8-handle, 9-tapping screw, 10-packing ring, 11-are pricked silk, 12-floor top reinforcement, 13-floor template, 14-floorslab concrete surface layer.

The specific embodiment

Further specify the example structure of the utility model below in conjunction with accompanying drawing.

Like Fig. 1, Fig. 2; Big cone 1, small cone body 2, cover plate 4 all adopt the thick Q235B steel plate of 3mm processing and fabricating to form; Big cone 1 is processed the agent structure that is combined into the notch cuttype mould with small cone body 2 through welding manner, and the same absolute altitude of the upper inside wall place equidistance of big cone 1 is welded with four projections 6, and cover plate 4 is shelved on the projection 6; Can open, cover plate 4 be provided be convenient to guide and support carry ear 5; The outer wall welding handle 8 suitable for reading of big cone 1.

The outer wall of big cone 1 is welded with four hook 7 (welding position are corresponding one by one with the projection 4 of inwall).An end of pricking silk 11 is connected on the hook 7, and it is fixing that the top reinforcement 12 of the other end and floor is tied up button.

The base plate of big cone 1 and the base plate center of small cone body 2 are equipped with the circular hole 3 of a diameter D=6mm, and tapping screw 9 inserts two circular holes 3, and lower end and flooring wooden form 13 are tightened.The upper end of tapping screw 9 is installed with packing ring 10.

Fig. 3 is the user mode sketch map that compound conical floor is reserved the hole mould.When reserving entrance construction; Earlier mould (surfaces coated is brushed with release agent) is placed on the floor template 13 of cast-in-situ floor gutter hole to be provided position; Preset anchor point on upper and lower two circular holes 3 and the floor template 13 is carried out centering, and the tapping screw 9 that will be installed with packing ring 10 again is punctured in the circular hole 3 and with flooring wooden form 13 to be tightened, and the location of promptly accomplishing mould is with preliminary fixing; Adopt an end of four 22# number bundle silks 11 to be connected with four hooks 7 of big cone 1 respectively at last; The other end respectively with floor top reinforcement 12 crosspoint of the reinforcing bar (place) colligation, prick silk 11 for four and the Ben Mola knot tightened from four direction, mould is fixed; Cover cover plate 4, prevent that concrete from getting in the big cone.So far, accomplish the burying work beforehands such as laying, locate, fix that compound conical floor is reserved the hole mould, can build floorslab concrete.At the final set initial stage of floorslab concrete; Can carry out demoulding dismounting work: open movable cover plate 4, unclamp self-tapping screw 9 then and cut off bundle silk 11, knock the outer wall of big cone 1 more gently; So that form loosening delamination between mould and the floorslab concrete; Upwards guide and support handle 8 at last, mould is extracted from floorslab concrete, promptly present up big and down small compound notch cuttype circular cone and reserve the hole at floorslab concrete.Regain behind the mold cleaning, can have enough to meet the need use.
