Abstract
The invention relates to a floatation resistant construction method of a cast-in-site concrete hollow floor system. The cast-in-site concrete hollow floor system consists of a reinforced steel tie rod of which one end of is hooked on reinforced steel ribs while the other end is fixed on transverse bracing purlines, a load-bearing plate, nuts and gaskets. The invention can accurately control the thicknesses of cast-in-site hollow slabs and has strong floatation resistance; the invention ensures that floatation resistant points are fewer and more accurate compared with the prior floatation resistant technology, has simple construction and can ensure the construction quality. The invention is suitable for the engineering having suspended ceiling requirement and the reinforced steel tie rods can be used as tie rods of suspended ceilings at the late stage as well.
Description
Affiliated technical field
The present invention relates to a kind of anti-floating construction method of cast-in-situ concrete cast-in-place hollow slab, belong to buildings in general structure field.
Background technology
At building field, along with the large-span concrete structure is increasing, increasing floor adopts the concrete hollow building roof technology.All there is the problem of doing anti-floating in cast-in-place concrete hollow building roof when construction.Way was to be connected the construction trouble with the template bottom with iron wire in the past, can not accurately control protective layer thickness up and down, and iron wire shakes easily disconnected (having ruptured when iron wire is tightened sometimes) and is not easy discovery when concreting, can not control more accurately and effectively.
If can adopt rational construction technology method to reduce the engineering time, can better guarantee construction quality again simultaneously, be very favourable to promoting the cast-in-place concrete hollow building roof technology.
Summary of the invention
At some shortcomings that prior art exists, the anti-floating construction method of a kind of cast-in-place concrete hollow building roof provided by the present invention has higher intensity, can control the cast-in-place hollow slab thickness of slab more accurately, and efficiency of construction is very high simultaneously, does not have the disconnected problem of shaking.
The technical solution adopted for the present invention to solve the technical problems is: the anti-floating construction method that forms a kind of cast-in-place concrete hollow building roof.It is that the steel bar rod that is connected in top reinforcement and stull purlin is arranged, bearing plate, and nut is formed.Be connected with top reinforcement by steel bar rod, bearing plate is finished with nut screwing clamping.
The advantage of this kind anti-floating: save material, the thickness of slab size Control is accurate, and anti-floating power is strong, and what the anti-floating technology that anti-floating point is general relatively will be done lacks, and control area is big, and construction is simple, can guarantee construction quality.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a cast-in-situ concrete hollow slab cross-sectional configuration schematic diagram in this job practices.
Fig. 2 is several obturator form of fractures of cast-in-situ concrete hollow slab in this job practices.
Among the figure: 1. steel bar rod, 2. bearing plate, 3. nut, 4. packing material, 5. concrete, 6. top reinforcement, 7. lower floor's reinforcing bar, 8. template, 9. stull purlin, 10. composite figure, 12. circles of broken line shape, 11. rectangles and circular arc.
