Abstract
The utility model relates to a cast-in-situ plate with a concrete structure, comprising a box top plate and a side formwork which are cast in a plane die integrally, the polygonal box top plate with more than four sides is arranged in the middle of a precast slab, and the side formwork is in flexible connection with the box top plate. The cast-in-situ plate also includes a box bottom plate that coincides with the periphery of the box top plate and is cast independently, and the box bottom plate, the box top plate and the side formwork jointly form a closed box body. The manufacturing process is simplified by using the cast-in-situ plate to make hollow floors, errors will not take place easily when the plates are butt-jointed and pieced together to form the box body, and the combining process is simple and rapid. The utility model is applied to various hollow floors, roofs, wall bodies, foundation slabs and open-web bridges of cast-in-situ reinforcement concrete or prestressed reinforcement concrete, and is particularly applied to hollow beamless floors.
Description
Technical field
The utility model relates to a kind of constructional materials, and what especially relate to a kind of concrete structure is used to make the employed opening box of hollow building cover plate.
Background technology
In the past, the most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure, this floor structure has advantages such as the fast and cost of speed of application is low, but owing to firmly do not connect between adjacent two precast hollow slabs, only use cement mortar blind, therefore globality is poor, phenomenons such as slit cracking, infiltration often occur.In order to address the above problem, occur the method for Cast-in-place concrete floor now under construction, but will use a large amount of templates during construction, not only increased expense, the speed of application that also slowed down has prolonged the duration.
" 200610077560.2 " number patent disclosure a kind of opening box for concrete structure, comprise boxboard, template all around, last boxboard is separate prefabricated member with template all around, it on boxboard by supports support on interim bed die, all around template hang over support member or/and on the boxboard.Like this, around last boxboard lid is pressed on the template, last boxboard is an amalgamation prefabricated component after the split with template all around, can make separately carrying of member, and go up boxboard by supports support on interim bed die, template hangs over support member or/and go up on the boxboard all around, can make things convenient for assembly unit, and can the superimposed transportation of piecemeal, not cracky, help ensuring the quality of products, reduce cost.
But this separate prefabricated member need be shaped on the connector of amalgamation, connection or suspension in advance on member, makes complicatedly, and needs on-site consolidation when using, and occurs the problem of assembly unit butt joint dislocation easily.
The utility model content
(1) technical problem that will solve
The purpose of this utility model is to provide that a kind of one is cast, on-the-spot amalgamation butt joint forms opening box that hollow arch without beam uses casts constructional materials.
(2) technical scheme
In order to achieve the above object, the utility model is taked following scheme:
The utility model is a kind of concrete structure cast-in-place spare, be included in the roof box and the side template that are made into integration in the plane mould, the centre of described precast plate is the above polygonal roof box in four limits, between described side template and the described roof box for flexibly connecting, like this, side template can be turned up at the roof box periphery, forms an opening casing.
Wherein, the rectangle that described side template equates for the width that stretches out laterally from described roof box, each limit of described roof box all is connected with described side template, and described flexibly connecting is wire gauze connection or cloth connection.
Wherein, the above polygon in described four limits is quadrangle, pentagon or hexagon.
Wherein, the top board lead angle of peripheral oriented same the processing of described roof box, the same one side of one side that described side template is connected with described roof box and described top board lead angle handles that side plate lead angle, described top board lead angle and described side plate lead angle sum are arranged is 90 to spend.
Wherein, concrete structure cast-in-place spare of the present utility model, also comprise a box plate that coincides with the roof box periphery, described side template is formed the casing under shed with described roof box after same direction bending, described box plate periphery matches under shed with described casing, and box plate and opening box are to being connected into the casing of a sealing.
Wherein, described box plate is frustum or arc surfaced, and the top margin of frustum summit or arc surfaced is 1 centimetre to 3 centimetres with respect to box plate place planar projections height, and described side template outer side edges is watered and is shaped on wire gauze or cloth.
Wherein, inside when described roof box, side template and box plate form casing is densely covered with pit near surface, jointing edge place, and when when box house is placed support bar, densely covered pit can increase friction, prevent that support bar from sliding, support bar has increased the intensity of casing greatly.
(3) beneficial effect
1) different piece of opening box uses a mould one to cast simplified manufacturing process; Roof box flexibly connects with side template is in the same place, and is not easy to occur error when piecing together an opening box, and the amalgamation process is simple, rapid, only need be at the inner support bar of placing of opening box, amount to side template then, cover box plate, get final product with quick cement stabilization at joint.
2) top board lead angle and side plate lead angle make that contraposition was more accurate when roof box and side template docked, and avoid occurring dislocation.
3) box plate is frustum or arc surfaced, and when the roof fill concrete, the box plate of frustum or arc surfaced can make the bottom ventilation of casing good.
4) the side template outside is watered and is shaped on wire gauze or cloth, in the each several part amalgamation of casting, the process that covers, uses quick cementing butt joint and lap-joint, can make casing more firm.
Inside when 5) roof box, side template and box plate form casing is rough and uneven in surface near surface, jointing edge place, increases the friction of support bar in the casing, avoids support bar to slide, and support bar has increased the intensity of casing greatly.
