Description
Technical field:
This utility model building engineering construction field, particularly to be a kind of coagulation prepared hole die.
Background technology:
Modern architecture building mainly use and first do chassis body, carry out the assembling of second phase inner facility after chassis body binds again.Indoor are given, the pipeline of draining is all to assemble with the main body construction reserving hole later stage again.Former concrete floor flat board reserving hole mainly uses the pvc pipe of appropriate length or conduit peschel to make provided pipe, then pvc pipe or conduit peschel iron wire, iron nail are fixed on the position of needs, after concrete initial set, further take out pvc pipe or conduit peschel, complete the construction of preformed hole.This method needs workmen's accurate assurance of operation to take the pipe time, has taken early concrete slump, can not form required hole, the most then can not take provided pipe, waste, and when pouring into a mould concrete, due to the side pressure of concrete, the provided pipe using iron wire fixing the most all can produce displacement.
Utility model content:
The purpose of this utility model is to overcome above deficiency, it is provided that a kind of simple in construction, constructs, installs, convenient fixing, and the suitability is strong, saves time, laborsaving, long-lived prepared hole die of concrete.
The purpose of this utility model is achieved like this:
This utility model prepared hole die of concrete, including the up big and down small circular cone stage body matched with concrete preformed hole, the top board that is fixed on circular cone stage body top, top board centre bore, the bottom centre hole of leukorrhagia mounting of roof plate groove is had on opposite position respectively bottom top board and circular cone stage body, equipped with lower roof plate in lower roof plate mounting groove, the screw rod of top tape handle sequentially pass through top board centre bore, bottom centre hole, lower roof plate and stretch out outside lower roof plate and lower roof plate is fixed on screw rod, screw rod bottom is taper, and position screw rod being positioned at outside top board is equipped with top board.
Having the tubular being positioned at outside top board centre bore, bottom mesopore to support in above-mentioned frustum of a cone body, intensity is high.
This utility model have employed up big and down small circular cone stage body, and the outlet aperture of the reserved hole shaped of construction is in magnifying state, so after concrete completes solidification, delivery is very easy to.This utility model have employed when the screw rod that bottom is the top tape handle of taper is installed and is prone to fixing, and accurate positioning, location can be as accurate as millimeter；During taking-up light, quick, time saving and energy saving.Screw rod uses coarse groove screw rod, durable in use during construction at the scene, is hardly damaged.
This utility model simple in construction, constructs, installs, convenient fixing, and the suitability is strong, saves time, laborsaving, durable in use.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model schematic perspective view.
Fig. 3 is utility model works schematic diagram.
Detailed description of the invention:
Seeing Fig. 1, Fig. 2, this utility model prepared hole die of concrete, including the up big and down small circular cone stage body 1 matched with concrete preformed hole, the top board 2 that is fixed on circular cone stage body top.Top board centre bore 3, the bottom centre hole 5 of leukorrhagia mounting of roof plate groove 4 is had on opposite position respectively bottom top board and circular cone stage body.Equipped with lower roof plate 6 in lower roof plate mounting groove.The screw rod 8 of top tape handle 7 sequentially pass through top board centre bore, bottom centre hole, lower roof plate and stretch out outside lower roof plate and lower roof plate is fixed on screw rod.Screw rod bottom is cone.The position being positioned at outside top board on screw rod is fixed with top board 9.
Seeing Fig. 3, during utility model works, screw rod with handles sequentially passes through top board centre bore, circular cone stage body bottom centre hole and lower roof plate and stretches out outside lower roof plate and be integrally fixed in rear thread precession template 10 with lower roof plate, then carries out concrete 11 and pours into a mould.After the solidification of concrete casting complete, reversely rotating handle, screw rod drives lower roof plate upwards, and this utility model is taken out of the concrete of casting solidification.
