Abstract
The invention discloses a core mold for concrete filling, which comprises integral basin-shaped molds (1). The core mold is characterized in that basin mouths of the basin-shaped molds (1) are provided with circular waterstop rings (3). The basin mouths of the basin-shaped molds are provided with the circular waterstop rings, so when a floor slab produces cracks along the side wall of a shuttering because of aging and so on, the waterstop rings can prevent the cracks from running through and ensure that liquids such as water and oil as well as gas on the surface of the floor slab can not permeate and pass through the waterstop rings arranged at the basin mouths of the basin-shaped molds when permeating into the cracks, thereby achieving good leakage prevention and seepage prevention; at the same time, the basin-shaped molds are integral basins, so when the basin-shaped molds have certain conicity, basin-shaped components can be superposed and stacked in the transportation process to save transportation space and reduce transportation cost, thereby achieving the aims of the core mold. The core mold is suitable for hollow floors, roofs, wall bodies, foundation slabs and bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete, and is particularly suitable for the hollow floors.
Description
(1) technical field
The present invention relates to a kind of core die for concrete filling.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ hollow floor plate becomes pole, and as paper tube, plastic pipe, metal bellows, core light material etc., these tubular core molds or member mainly consider to find time concrete, reduce floor weight.Is that ZL99249798.1, name are called " filling reinforced concrete fiber reinforcement type thin-wall member " utility model patent as the applicant in the patent No. of application on November 29th, 1999, it discloses a kind of thin-wall mould-shell member, comprise upper plate, on every side sidewall, go to the bottom, upper plate, on every side sidewall, going to the bottom surrounds the polyhedron cavity, upper plate, on every side sidewall, going to the bottom contains fabric reinforcement.And for example the applicant is 01140106.0 in the application number of application on November 23 calendar year 2001, publication number is CN1356442, name is called " a kind of mould with cavity structure for casting reinforced concrete floor slab " application for a patent for invention, it comprises " upper plate; sidewall on every side; go to the bottom; upper plate; sidewall on every side; going to the bottom surrounds the polyhedron cavity former component, upper plate, sidewall on every side, the reinforces such as containing fiber or gauze wire cloth of going to the bottom, this member in being applied to floor after, when the crack appears in the weak part at floor, having water is penetrated into below the floor, therefore, develop a kind of novel cast-in-place reinforced concrete filling core for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of core die for concrete filling, have splicing conveniently, water resistance is good, and speed of application is fast, characteristics such as convenient transportation.
Solution of the present invention is on the basis of existing technology, comprises whole basin-shaped molds, it is characterized in that the ringed seal ring of basin mouth of basin-shaped molds.Like this, the ringed seal ring of basin mouth of basin-shaped molds, when floor because reason such as aging is when the formwork sidewall produces the crack, seal ring can prevent that the crack from running through, when making water, wet goods liquid and gas on the floor face in being penetrated into the crack, porous does not pass the seal ring that basin-shaped molds basin mouth is provided with, and has well played the effect of leakproof, antiseepage; Simultaneously, basin-shaped molds is whole basin, when basin-shaped molds has certain taper, in transportation, the basin-shaped components superposed and stacked not only can be saved transport space, also reduce cost of transportation, when the good core of assembly unit is applied in the superstructure, can also reduce the deadweight of superstructure; Thereby reached purpose of the present invention, be applicable to that hollow building cover, roof system, body of wall, sole plate and the bridge of cast-in-situ reinforced concrete or prestressed reinforced concrete uses, be particularly useful for hollow building cover and use.
Feature of the present invention is that also seal ring is a seal ring in the rib at concrete rib middle part.Like this, after two basin-shaped molds amalgamations, form seal ring in the rib at the amalgamation position, when loose tool was applied in the floor, seal ring was in cast-in-place concrete hidden rib middle part in the rib, can effectively prevent the crack infiltration.
Feature of the present invention also be to have on the seal ring annular to cut off the water supply cloudy ring of sealing that groove shaped becomes or the annular sealing sun ring that raised line forms of cutting off the water supply.Like this, have annular to cut off the water supply on the seal ring cloudy ring of sealing that groove shaped becomes or the annular sealing sun ring that raised line forms of cutting off the water supply has been strengthened the effect of seal ring, makes more difficult infiltrations such as liquid or gas pass floor.
Feature of the present invention also is the positive anchor ring of seal ring or/and cloudy anchor ring has build-in thing or the build-in structure that strengthens the seal ring build-in or/and encircle the limit.Like this, the positive anchor ring of seal ring is or/and cloudy anchor ring has build-in thing or the build-in structure that strengthens the seal ring build-in or/and encircle the limit, when core is applied in the cast in situ concrete floor, the build-in thing of the enhancing seal ring build-in that is provided with on the seal ring or build-in structure combine with Cast-in-place concrete, make more firm the combining of seal ring and floor, strengthened the antiseepage of seal ring, the effect of leakproof.
Feature of the present invention is that also the build-in thing is silk, muscle or net.Like this, the build-in thing is silk, muscle or net, and diversified build-in thing is conveniently gathered materials on the spot, and has saved cost.
