Description
The application be that July 28, application number in 2004 are 2004101551830 the applying date, name is called the dividing an application of application for a patent for invention of " a kind of die in use for molding component of concrete filled double thin wall ".
(1) technical field
The present invention relates to a kind of non-loose core pore-creating cast-in-situ reinforced concrete hollow slab.
(2) background technology
At present, cast-in-situ reinforcing steel bar concrete hollow slab, particularly cast-in-situ reinforcing steel bar concrete hollow slab non-core-drawing pore-creating technology generally adopt light-wall pipe or thin-walled box filled, can satisfy the find time needs of concrete of various different hollowcore slabs.Is that CN1462680A, name are called " tool for shaping hollow tube " as the applicant in the publication number of application on May 29th, 2002, it is characterized in that it comprises two interface limits, open-shut type elasticity tube, shape keeping piece, clamp part, the interface limit is fixed on the open-shut type elasticity tube wall limit along its length, shape keeping piece is wrapped in the end of open-shut type elasticity tube, and clamp part is locked on the interface limit or holds tightly on open-shut type elasticity tube.Like this, tool for shaping hollow tube in use, unclamp clamp part, open-shut type elasticity tube trails, and fibrous composite slip thereon paves, bulkhead is put at two ends, with the open-shut type elasticity tube parcel shape keeping piece that trails, buckle clamp part then, maintenance is to the stipulated time, the demoulding gets final product, but hollow section intensity height, good integrity one-shot forming, the production efficiency height made like this; Simultaneously, be square, polygon hollow pipe component production for ease of shape of cross section, can on open-shut type elasticity tube, be vertically arranged with vertical soft intermediate zone or flexible transition bar or the hinge strap that is easy to amount to.Like this, tool for shaping hollow tube can successfully be amounted to around the corner, and intensity height, flexible good, long service life.But this tool for shaping hollow tube is mainly used to produce the circular hollow pipe component at present; And also need to formalize by shape keeping piece, also include the interface limit simultaneously, it produces relatively trouble, and structure is also relatively complicated; Except that having described the production that shape of cross section is square, polygon hollow pipe component, other describes in application documents for peviform or other polygonal member.And for example the applicant on the November 29th, 1999 of SEPARATE APPLICATION simultaneously application number be that 99115665.X, name are called the patent of invention of " fiber reinforcement-type light-wall conduit for reinforcing steel bar concrete filling (box) and manufacture method thereof ", and application number is 99115666.8, name is called the patent of invention of " fiber-reinforced thin-wall box for filling cast-in-place reinforced concrete and manufacture method thereof ", prepared light-wall pipe or thin-walled box can be openings, seal the light-wall pipe that then can make sealing or the thin-walled box of sealing if having; The mould that is adopted in its manufacture method has former or formpiston.As former, from they accompanying drawing as can be seen, it comprises side form face and bed die face, side form face and bed die face surround former, and this former is the former of integral mold plate, in actual use, demoulding inconvenience, therefore the light-wall pipe of opening or thin-walled box cracky, develop a kind of novel non-loose core pore-creating cast-in-situ reinforced concrete hollow slab for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of non-loose core pore-creating cast-in-situ reinforced concrete hollow slab, have characteristics such as simple in structure, easy to manufacture, that intensity is high, cost is low.
