Description

A kind of hollow floor slab with small dense ribs
[technical field]
The present invention relates to realize a kind of hollow floor slab with small dense ribs and manufacture method thereof.
[background technology]
The cast-in-place concrete hollow building roof of applying at present is in the base growth of traditional precast hollow slab and solid arch without beam, I am in the ZL98231113.3 patent of invention " concrete thin-wall cylindrical shell member " of invention in 1998, solved the non-technical barrier of taking out heart pore-forming technique of cast-in-situ hollow building roof, it is poor to have overcome the whole building structural performance of bringing because of precast hollow slab, the easy crack of superstructure, span is little, it is big that the problem that supporting capacity is low has solved cast-in-place solid arch without beam steel concrete consumption simultaneously, building is from great, the foundation cost height, defectives such as cost increase.Though cast-in-place concrete hollow building roof has above-mentioned superiority, but itself also exist the bidirectional stress design indeterminate, floor hollow rate low (being generally 20%--40%), press during construction outside the design layer cloth muscle, to consider also that " concrete thin-wall cylindrical shell member " single member is fixed, the problem of single member anti-floating and integral cover anti-floating, on a large scale with having certain limitation under construction.
At the prior art above shortcomings, the present invention is proposed.
[summary of the invention]
The object of the invention has overcome the prior art shortcoming, provides a kind of and can improve the superstructure hollow floor slab with small dense ribs of bidirectional stress in length and breadth.
The present invention is that a kind of hollow floor slab with small dense ribs mainly is the formwork that replaces prior art with compound thin-wall box body, form cavity behind the fluid concrete in the floor, cavity is organically combined enclosed cavity with compound thin-walled box bottom and floor base plate cement mortar, form on an empty stomach, reach close rib spacing and dwindle, prevent under the effect of superstructure vertical load, panel produces local buckling, base plate can be evenly stressed, avoids concrete cracking and guarantee that soffit is smooth.Solve the problem that prior art exists, reached the purpose of this invention.
For achieving the above object, the basic design of technical scheme provided by the present invention is as follows: a kind of hollow floor slab with small dense ribs, comprise post, solid band, the solid close girt strip of band steel bar concrete, the panel and the compound thin-wall box body of band steel bar concrete, described compound thin-wall box body lower end is provided with the book base plate with described empty stomach close rib building roof one-time cast-forming, described thin base plate is the thin base plate that cement mortar and compound thin-walled box bottom are composited, described compound thin-wall box body is set directly on the cast-in-situ hollow close rib building roof template outside the distance post outer rim 200mm, and compound thin-walled box bottom and cast-in-situ hollow close rib building roof template keep less than the 15mm space.
Contain the gauze wire cloth of rhombus, alkaline-resisting or alkali resistant glass cloth, plastics screen cloth reinforced materials in the described thin base plate.
The wall thickness of side plate and base plate is identical around the described compound thin-wall box body, and the wall thickness of top board is more than or equal to the wall thickness of four side plates and base plate.
The casing of described compound thin-wall box body for adopting cement mortar and reinforced materials under the effect of mould, to be composited, four limits are provided with down water chestnut to compound thin-wall box body water caltrop at the bottom of water chestnut or the compound thin-wall box body in order to fall, and described compound thin-walled box shape is spherical or cube-shaped for being preced with.
Before laying compound thin-wall box body, lay rhombus or reticular pattern reinforced materials earlier.
In the described close rib or panel be embedded with water, electricity, fire-fighting pipeline.
The invention has the beneficial effects as follows:
The present invention can realize large span, big load, structural safety is reliable, bidirectional stress is clear and definite, easy construction, reduce cost, and has disposal pouring, the effect of smooth sealing close rib building roof cavity.

[specific embodiment]
Embodiment 1:
As shown in Figure 1, hollow floor slab with small dense ribs of the present invention, it comprises the solid close girt strip 1 of being with steel bar concrete, the panel 2 of band steel bar concrete, compound thin-wall box body 3, be arranged on the book base plate 4 of casing 3 lower end one, book base plate 4 is by diamond wire net or other shape gauze wire cloth, the plate of reinforced materials such as alkaline-resisting glass cloth or alkali resistant glass cloth or plastics screen cloth and cement mortar 5 moulding, compound book wall casing 3 base plates and reinforced materials 5 when steel bar concrete empty stomach close rib building roof is cast-in-place, under the effect of vibrator, make cement mortar penetrate into the bottom of compound thin-wall box body, the bottom panel of compound book wall casing 3 and the cement mortar of infiltration organically combine the thin base plate 4 that forms the close rib cavity of sealing.Owing to new thin base plate 4 and the solid close rib 1 of steel bar concrete and steel bar concrete panel 2 and compound thin-wall box body 3 disposal pourings that form, strengthen the overall structure performance of building greatly again, alleviated the building deadweight, overcome the base plate crack, improved the characteristics of construction speed.The present invention can realize large span, big load, structural safety is reliable, bidirectional stress is clear and definite, easy construction, reduce cost, and has disposal pouring, the effect of smooth sealing close rib building roof cavity.
The present invention realizes like this, on the superstructure template, lay net post beam and little close rib steel muscle with colligation, lay bottom panel simultaneously with rhombus or other shape gauze wire cloths and other reinforced materials, lay, fix the compound thin-wall box body of having made, the colligation slab reinforcement when producing buoyancy, is being fastened close girt strip bottom reinforcement bars with the 12# iron wire and is being passed the template colligation fastening pole on pole or with the 12# iron wire, penetrate template, colligation is on little close girt strip bottom reinforcement bars.Carry out water, electricity, fire line set aside pre-embedded, use the pumping of concrete cast-in-site, electromagnetic shaker constantly vibrates in the little close girt strip around the compound thin-wall box body, maintains, tears open the superstructure template.
Embodiment 2:
As shown in Figure 2, on other basis identical with embodiment 1, the difference of present embodiment is that the water caltrop of compound thin-wall box body 3 is for falling water chestnut (shown in 4-1,4-2), the book base plate 4 that is arranged on casing 3 lower ends is sectional type, economical with materials again when reaching the object of the invention only is set by the type book base plate 4 in the relevant position, lower end of each casing 3.
Embodiment 3:
As shown in Figure 3, on other basis identical with embodiment 1, the difference of present embodiment is that this casing 3 is whole casing, and compound thin-wall box body 3 water caltrops are for falling water chestnut, shown in Fig. 4-3.
The manufacture method of the foregoing description mainly may further comprise the steps
A) on the superstructure template, lay beam column and little close rib steel muscle with colligation;
B) lay bottom panel simultaneously with rhombus or other shape gauze wire cloths and other reinforced materials;
C) lay, fix the compound thin-wall box body of having made;
D) colligation slab reinforcement;
E) when producing buoyancy, fastening close girt strip bottom reinforcement bars with the 12# iron wire and passing the template colligation and on pole or with the 12# iron wire, fastening pole, penetrate template, colligation is on little close girt strip bottom reinforcement bars;
F) carry out water, electricity, fire line set aside pre-embedded in panel and close rib.
Those skilled in the art can carry out other change and modification after reading patent specification of the present invention, but these changes and modification are all within the claim protection domain that the present invention is awaited the reply.
