Abstract
The present invention provides one new kind of hollow plate girder and its construction process, and aims at solving the difficult problems of hollow plate girder in demolding and reusing hollow inside mold. The hollow plate girder has opened inside space. The construction process of the hollow plate girder includes: setting stuffing in the place corresponding to the hollow part inside the hollow plate girder, depositing concrete and taking out the stuffing to form the hollow structure. The stuffing may be formed with local material and reused. The said construction process is simple, economic and suitable for the construction of different hollow concrete plate girders.
Description
Technical field
The present invention relates to building structure, particularly the construction of reinforced concrete hollow slab, beam.
Background technology
Concrete core unit, beam have from heavy and light, materials economize, the bearing capacity advantages of higher, its shortcoming is that hollow internal mold can't the demoulding, the construction technology complexity.Because constructional difficulties, the hollow form of hollowcore slab, beam generally also can only adopt circle, and the construction form is generally only prefabricated, and is seldom cast-in-place.
As adopt other hollow form cast-in-place, then must adopt disposable hollow loose tool (as filling hardboard, faggot core, giving and bury hollow box etc.), because hollow mould can't can only disposablely use in the demoulding, thereby the cost of construction is higher, and the scene is cast-in-place construction seldom.
One of reason that causes existing hollow slab beam cast-in-place construction difficulty is that the cavity in the existing hollow slab beam is the space of a sealing.
Summary of the invention
Can't the demoulding in order to overcome existing hollow body construction internal mold, hollow mould can not a reusable difficult problem.The invention provides a kind of new hollow slab beam and job practices thereof, this hollow slab beam, its inner cavity is the space of an opening, adopt new job practices simultaneously, this method is built at hollowcore slab grain can take out packing material after finishing easily, packing material can be reused, and the function of use according to floor requires autotelic selection packing material to fill and enclosed cavity simultaneously.
Specific embodiments of the present invention are: the hollow part in hollow slab beam, earlier with packing material installation in position (fillings), wait fluid concrete to finish after, thereby in hollow slab beam formation structure hollow body.
Entity is filled construction method, the hollow part in hollow slab beam, earlier with entity packing material installation in position (filling), wait fluid concrete after.By the hole on the plate-girder with all or part of taking-up of packing material, thereby in hollow slab beam, form cavity.
The entity packing material can use various solid materials, for example whole bulk material (as the foams of lighter weight etc.), disperses bulk material, discrete material, flexible material, fluent material.Discrete material is selected natural sandstone, saw foam, earth, ash etc.; Also industrial goods be can select, quarrel, baton round etc. abandoned as industry and life; Bulk material such as light-weight brick, hollow pot, also can be faggot core etc.; , fluent material such as water, mud, mud liquid etc.
The selection of packing material should consider to gather materials on the spot in principle and the construction facility (recovery) and require autotelic selection packing material to fill according to the function of use of floor.For example the heat preservation and soundproof floor of having relatively high expectations should select for use heat-insulating and noise-insulating material to do packing material (seeing embodiment for details)
The way of recycling of packing material is a lot, can be tear open, take out, dig, get, mode such as dissolving.
Cement paste flows into packing material or produces reaction during for fear of fluid concrete, simultaneously also for the convenience of the demoulding.Should establish separation layer in entity packing material outside, insolated layer materials has a lot, as plastic paper, mineral wool board etc.
Hollow body is filled construction method, in the hollow part of hollow slab beam, earlier with packing material (hollow body) installation in position (filling), wait fluid concrete after.Thereby in hollow slab beam, form cavity.
The shape of hollow body can be determined as required, can be pipe, basin, polyhedron isometric(al) body.The material of hollow body can be gathered materials on the spot.
Hollow body is characterised in that it is non-enclosure space.The cavity that hollow body forms in hollow slab beam has specific purposes.
Hollow body also can be the semiclosed empty van of sheet material assembly unit, by underfloor (on) hole of face takes out packing material, thereby form hollow body in hollow slab beam.
Capsules is filled construction method, in the hollow part of hollow slab beam, will inflate (water) Capsules material installation in position (filling) earlier, wait fluid concrete after.Capsules is taken out the cavity up and down by hollow slab beam, thereby in hollow slab beam, form the structure hollow body.Capsules has a plurality of independent air bags.
A kind of hollow slab beam: it is made up of upper plate, lower plate and intermediate connector and cavity.It is characterized in that: in hollow slab beam upper face or lower face perforate, the enclosed cavity in the hollow slab beam is opened the space that makes it to become an opening, the space of being convenient to form removal and using cavity body.
Connector can be various, can be floor, or column.Finish and to cover at hollow slab beam upper face or lower face perforate construction, also can give over to decorate and use.
Compared with prior art, the present invention has following advantage.
1, discrete material filling construction method is a kind of very easy, economic hollow slab beam job practices.It is applicable to the reinforced concrete hollow slab beam construction that any form is hollow.Discrete material can be gathered materials on the spot, and reuses.Construction still is effective to municipal bridge (case beam).
2, the floor higher to the heat preservation and soundproof performance requirement, it is effective more economically to adopt a prose style free from parallelism to fill construction method.
3, the construction technology that adopts hollow box body to fill the construction hollow slab beam is a kind of very easy, hollow slab beam job practices of using.And can guarantee the compactness of lower plate concrete pouring.
4, adopt phoenix pipe and steel pipe to fill the construction technology of construction hollow slab beam, promptly can save indoor headroom significantly, realize that a plate uses more again.
