Many buildings in the worker China Democratic National Construction Association all adopt close rib steel tendon concrete structure, and way traditional during cast is all wanted support formwork and template, these formworks and template generally all are to adopt wooden or steel, and wooden repeat usage is low, consumption is big, and the moulding concrete is rough, steel, the cost height, from body weight, reuse the back has distortion more, in using, large-area splicing all has many shortcomings, draw, store and transport all pretty troublesome, take a lot of work, require great effort, more expensive naturally.Along with development of technology, the plastics system of some lightweights or glass steel substitute template and formwork begins to use to some extent, but actual conditions are not obtain promoting, its reason, these lightweights substitute the conversion that the plate shell only is a material, the problem that Steel-wood forming board and formwork exposed is not resolved, and acquisition cost is too high, template plastics or glass fiber reinforced plastic, greatly about about 500 yuan, construction enterprises are difficult to accept, and in addition, the breakage rate after the form removal is also very big, therefore, restricted applying of this class mould.The utility model just is based on this present situation and studies, and proposes the incorporate lightweight mould of a kind of novel template and formwork, through test of many times, has obtained satisfied effect.

The utility model content

The purpose of this utility model provides a kind of light weight, the intensity height, exempt from dismounting, but sound insulation, the dense rib type template that plate is shell integrated, overcome tradition with the defective that mould exposed except that deenergizing, the reinforced concrete multi-ribbed plate and the reinforced concrete multi-ribbed beam that come formwork to water to outpour with it, dead load is light, bearing He carries greatly, do not see the form of close rib behind the casting complete, identical with the flat form of slabbed construction, only needing the butt joint place to do the Puttying processing gets final product, therefore see, watering the multi-ribbed plate girder construction that outpours with close rib template is a kind of ideal stress form, and, can save steel more than 30%, and the saving of labor, save time, laborsaving, the purchase commodity and the wooden form of its template are close, and be very economical.

Concrete technical scheme of the present utility model is as follows:

Template type: for having certain thickness square castable, around its bottom, move back the certain width of platform, it moves back table top and can be the inclined-plane, at four side wall centers places of moving back table top top block, respectively leaves the groove of a long strip type.Used core when described square block is the close rib concrete plate of cast, described beveled move back platform used bed die when being the close rib concrete plate of cast, the groove that is stayed, and convenient carrying when being used to splice on the one hand, the aspect is used to pour into a mould the snap-in location of back and girt strip in addition.

The making of template: as aggregate, as cementitious materials, dose certain acidproof pricker dimension or screen cloth with the polyphenyl plate particle, stir that the cast back is dried naturally to form admittedly in the force part of template with high-mark cement or DFB glue.

The common-use size of template: consider easy construction and load requirement, its thickness is 150～400mm; Bottom width is 600～900mm, wherein moves back about each 40mm of wide height of platform bed die.According to different building structures and standard width of a room in an old-style house span, the seriation preparation.

The assembly unit of template is used: support system is identical with common column keel rack combination way, support system put reserve after, block-by-block extends and tiles, and for some post angles or side bar place, can carry out cutting process, arrangement of reinforcement is carried out according to designing requirement in the back, shop, the rib width minimum is 80mm therebetween, and single muscle still is double muscle configuration, is adjusted definite by the designer, after concrete pouring is solidified, need not delivery, be delivered for use with close rib concrete plate-girder.

The close rib template of the utility model has the following characteristics:

(1) from heavy and light, make beam slab closely staggered, bearing load is big, compares with general flat superstructure arrangement of reinforcement and can save steel about 30%;

(2) price is low, and is approaching with common formwork expense, uses back and Cast-in-place concrete multi-ribbed plate to form integral body, and smooth smooth under the plate, do not have the operation of stripping, and the Puttying processing of only making seam when handing over gets final product, and has both reduced labour intensity, has saved labour cost again;

(3) construction and installation are easy, and configuration arbitrarily can be cut some very places of rule uses of adaptation;

(4) soundproof effect is better than common cast-in-situ floor, and because the semi-closed state that template splicing back forms, hydration heat and moisture own that Cast-in-place concrete is produced distribute slowly, for good environment has been created in self maintenance.
