The utility model is characterized in that the filling body comprises a light inner die and a waterproof isolation layer coating the surface of the light inner die, and a reinforcing layer is arranged between the light inner die and the waterproof isolation layer; the grating consists of a cross bar and a group of limit division bar pairs arranged on the cross bar side by side; the cross bar consists of an upper cross bar and a lower cross bar, and the distance between the upper and the lower cross bar matches with the height of the inner die cross section; the division bar pair is arranged between the upper and the lower cross bar; a support leg with a fixed height is disposed at the lower side of the grating. The utility model has advantages of overcoming the technical defect of the prior art that the positioning operation is difficult, the construction speed is slow and the material consumption is large; achieving the accurate positioning and flotation resistance of the built-in core mould; reducing cost.
Description
Technical field
The utility model belongs to the common buildings construction equipment, particularly relates to a kind of cast-in-situ reinforced concrete floor anti-floating location combination built-in core mould that is applicable to.
Background technology
At present, the increasing engineering of building field adopts that prefabricated filling member is imbedded, the technology of concrete cast in situs.Can lay a plurality of filling die bodys in advance according to construction requirement at the scene in the actual engineering, will leave certain distance between the adjacent filling die body, so that concreting and on-the-spot little close girt strip.In order to prevent that filling die body is subjected to displacement, influences workmanship in concrete placement, the job site adopts each to fill the fixing method of die body more.
Because filling the steady job of die body and girt strip is at the scene by manually carrying out colligation, deviations can be occurred unavoidably and the little close girt strip and the thickness of concrete up and down can not be guaranteed, therefore to adjust accordingly, not finishing the fixing then work of building can't carry out, in construction, the fixed in place of this filling die body and adjustment process can consume a lot of times, and take a lot of labours, influence programming, and can cause the waste of colligation material.
Summary of the invention
The utility model provides a kind of combined disposable filling template of easy to use, accurate positioning for solving the technical problem that exists in the known technology.
In order to solve the problems of the technologies described above, cast-in-situ reinforced concrete composite core formwork provided by the utility model comprises grid and filling die body,
Wherein fill die body and comprise the lightweight internal mold of multiple type shape and the reinforcement watertight insulation on parcel lightweight internal mold surface, be provided with enhancement Layer between lightweight internal mold and the reinforcement watertight insulation;
Grid comprise cross bar and and one group of spacing parting bead coming on the cross bar right, described cross bar comprises cross tube and sheer pole, the matched in the spacing of upper and lower cross bar and internal mold cross section, described parting bead are between upper and lower cross bar, and its downside of described grid is formed with high surely leg.
Further, adjacent spacing parting bead between distance be unified default spacing, internal its shape of sheer pole of each spacing parting bead is with the corresponding arc in internal mold cross section, falls trapezoidal or waveform.
Further, described enhancement Layer is between lightweight internal mold upper surface and reinforcement watertight insulation, and the horizontal section of enhancement Layer is strip or frame shape.
Introduce below and use the utility model composite core formwork, realize the work progress of cast-in-situ reinforced concrete superstructure.
During construction, lay template earlier; Subregion setting-out on template marks the relevant position of composite core formwork in superstructure;
The girder of colligation superstructure (close girt strip) and lower floor's reinforcing bar;
Water power pipeline set aside pre-embedded is installed;
Composite core formwork is put in drawing position according to design, will decide high leg and lower floor's reinforcing bar binding or welds together, so composite core formwork position basic fixed;
The drawknot wire is set, wire one end is fixed on support system under the template, the other end and cross tube are fixed;
The top reinforcement of colligation superstructure; Concreting; Stripping.
Adopt the utility model composite core formwork that following technique effect is arranged: the grid of no leg contacts with the lower floor reinforcing bar by sheer pole or internal mold (some grid does not have sheer pole) are direct, there is not sufficient space to hold pipeline between lower floor's reinforcing bar and grid and the internal mold, the utility model composite core formwork is provided with high surely leg below existing grid, be that internal mold is lifted, between internal mold and the lower floor's reinforcing bar certain spatial accommodation has been arranged, then hydroelectric line needn't be walked around the laying work area of internal mold in advance, just can directly finish the laying of hydroelectric line; By spacing parting bead to and the spacing setting of upper and lower cross bar, realize relatively stable between grid and the internal mold; Adjacent spacing parting bead between distance be unified default spacing, adopt the unified spacing of setting, help the force balance of whole superstructure; Internal its shape of sheer pole of spacing parting bead is with the corresponding arc in internal mold cross section, falls trapezoidal or waveform, because its cross section of internal mold can be multiple shape, in the work progress if to use corresponding internal mold (promptly the lower edge in this internal mold cross section as arc, fall trapezoidal or corrugated), adopt its spatial accommodation that provides for hydroelectric line of cross bar in this practical composite core formwork to be better than common grid positioner; Be used with the drawknot wire,, play the effect of good anti-floating by further upper and lower spacing of stable falsework with internal mold.
The utility model composite core formwork is fixed in the grid by filling die body, leaves fixing distance between the adjacent filling die body, contingent die body rotation, dislocation when having avoided concreting.That composite core formwork has is easy to use, the characteristics of accurate positioning, composite core formwork directly can be used in construction, has omitted fixed in place and has adjusted the process of filling die body, has reduced the engineering time, has accelerated programming, has avoided waste of material.
The lightweight internal mold can be continued to use the foam pellet of foam-plastic blocks of the prior art, expanded pearlite sillar, expansion frog stone, foaming or aerating silico briquette, haydite silico briquette, straw husk cementitious materials piece, charcoal silico briquette or cementing.Like this, the utility model composite core formwork has sound insulation preferably, heat insulation, heat-insulating property, and light material kind diversity is drawn materials when being convenient to produce nearby, helps reducing production costs.Lightweight internal mold parcel watertight insulation can guarantee the unlikely suction of light material, segregation, has reduced the breakage rate of lightweight member; Be provided with enhancement Layer between watertight insulation and the lightweight internal mold upper surface and can prevent that in the process of building metal drawknot silk or cross tube produce stress deformation to the lightweight internal mold; The horizontal section of enhancement Layer is middle empty frame shape, helps saving material, because solid enhancement Layer tabular and middle empty frame shape can be realized same technique effect.
