Abstract
The installation and construction of the hollow tubular in the hollow reinforcement concrete beamless floor slab sets up two brackets made up of reinforcement between the underside of each row of the hollow tubular and the construction formwork, and then place two compression hollow tubular wave shape reinforcing on the hollow tubular, use the iron wire to connect the brackets and the compression hollow tubular wave shape reinforcing together. the compression hollow tubular wave shape reinforcing just inosculate the sheath of the hollow tubular because the compression hollow tubular wave shape reinforcing have the same wave shape with the radius of the hollow tubular, that completely restrict the hollow tubular having the slip displacement in the common action of the flowing concrete and vibrator, meanwhile restrict the hollow tubular floating upwards through the iron wire and the brackets fixing to the template. It cuts the cost, and saves the materials, and is easy to construct.
Description
Affiliated technical field:
The utility model relates to a kind of fabric structure, and being specifically related to cast-in-place hollow does not have hollow section installation constitution in the beam steel concrete building plate.
Background technology:
At present, cast-in-place hollow does not have the beam steel concrete building plate and has obtained in the whole nation using widely, and China Engineering Construction Standardization Association has issued " cast-in-place concrete hollow building roof tecnical regulations " CECS 175:2004 for this reason, and implements on April 1st, 2005.Preside over by concrete structure Professional Committee of China Engineering Construction Standardization Association, hold in Shanghai City on July 28th～30,2005 (national cast-in-place concrete hollow building roof structure technology exchanging meeting), publish " national cast-in-place concrete hollow building roof structure technology exchanging meeting " collection of thesis simultaneously, reflection has a variety of cast-in-place hollows not have hollow section installation constitution in the beam steel concrete building plate from the technology that exchanges, its hollow section installation constitution is more complicated all, make hollow section produce slide displacement under concrete that when carrying out concreting process, flows and the vibrating spear acting in conjunction, influence the workmanship of floor.When carrying out patent retrieval, do not retrieve about hollow section installation constitution patent.At the relevant speciality periodical and on carrying a work through the press relevant for hollow section installation constitution technology, but this part hollow section installation constitution technology relatively lost labor and material in the practice of construction process, quality control on construction is difficulty relatively.
Summary of the invention:
The utility model purpose is to overcome existing hollow section installation constitution complexity, quality control on construction relatively difficulty, hollow section are easy to generate shortcomings such as slide displacement, engineering construction cost height, a kind of easy construction that for this reason provides, saving construction can not have hollow section installation constitution in the beam steel concrete building plate to the cast-in-place hollow of any direction slide displacement with material, hollow section, have guaranteed that cast-in-place hollow does not have the construction quality of beam steel concrete building plate.
The technical scheme that the technical problem that the utility model solves is taked is: below each emptying core barrel and two supports by reinforcement fabrication are set between the construction formwork, this support must be fixed together with construction formwork, prevents to make hollow section to come-up in the concreting process.Hollow section is arranged above the placing rack according to certain spacing, then with two are placed on hollow section above corresponding with support of reinforcing bar of pressing the hollow section wave-likes, the reinforcing bar binding of support and pressure hollow section wave-like being connected and fixed between the gap of hollow section and hollow section with iron wire is clipped in the middle hollow section.
The beneficial effects of the utility model are: owing to press the reinforcing bar of hollow section wave-like that the wave-like identical with the hollow section radius arranged, what be placed hollow section toply just in time matches with the crust of hollow section, limited the displacement that horizontally slips that hollow section produces hollow section under concrete that flows and vibrating spear acting in conjunction fully, being fixed together by iron wire and support and template simultaneously, to have limited hollow section upwards unsteady.Reach easy construction, saved construction and use material, reduced the cost of engineering, guaranteed the purpose of the construction quality of engineering.
Description of drawings:
Following structure drawings and Examples further specify the utility model

Fig. 2 is for pressing hollow section wave-like reinforcing bar (2) facade shape figure, and A is the center distance A 〉=D+40mm of hollow section, and the maximum height of h must be less than 0.5 of hollow section (3) diameter, and the radius R of wave must be consistent with the radius R of hollow section (3).
Fig. 3 is the support (5) of reinforcement fabrication, its height 〉=40mm is the thickness of the steel concrete (1) below the hollow section (3), the selection of bar diameter should satisfy hollow section and steel concrete drop on top indeformable, the spacing B=900～1500mm of the support of reinforcement fabrication (5) leg.
Claims (2)
