Abstract
The utility model discloses a toothed web box-type steel and concrete composite flat beam, and belongs to the field of house building members. The composite flat beam comprises a prefabricated toothed web box-type steel beam and a cast-in-place concrete layer, wherein the prefabricated toothed web box-type steel beam comprises upper and lower flange plates and two toothed webs; the upper and lower flange plates are parallel to each other; the two toothed webs are symmetrically arranged between the upper and lower flange plates, and the upper edges and the lower edges of the corrugated webs are fixedly connected with the upper flange plate and the lower flange plate respectively; floorslab lapping surfaces are arranged on the lower flange plate on the outer sides of the two toothed webs. According to the composite flat beam, the box-type steel beam has a ladder-shaped cross section formed by the upper and lower flange plates with different widths and the two symmetric toothed webs; the toothed gaps of the toothed webs face downwards, so that the stability of the pressed flange plates can be improved, pre-buried pipelines can be conveniently laid and the subsequent pouring concrete and the section steel can conveniently form the stable integrated composite beam; the floorslab lapping surfaces are arranged on the lower flange plate on the outer sides of the two toothed webs, so that the mounting operation is convenient and the stability is good.
Description
Technical field
A kind of profile of tooth web of the utility model box steel concrete composite flat beam, belongs to building construction member field.
Background technology
At present, in building field, generally adopt girder steel or cast-in-situ steel reinforced concrete beam, reinforced concrete beam needs molding, and construction cost is high, and long construction period, wet trade are more.And the torsional property of girder steel is poor, durability and fire resistance are also very poor.Therefore, Novel steel concrete composite beam is subject to extensive concern.
Utility model content
The purpose of this utility model is to provide a kind of profile of tooth web box steel concrete composite flat beam, to improve torsional property, stability and the globality of beam, and effectively increases the space that utilizes of building interlayer.
A kind of profile of tooth web of the utility model box steel concrete composite flat beam, by prefabricated profile of tooth web steel beam with box shape and cast-in-situ concrete layer, formed, described prefabricated profile of tooth web steel beam with box shape is comprised of top flange plate, bottom wing listrium, profile of tooth web, top flange plate, bottom wing listrium be arranged in parallel, two blocks of profile of tooth webs are symmetricly set between upper and lower frange plate, its upper and lower both sides are fixedly connected with top flange plate, bottom wing listrium respectively, and the bottom wing listrium of two profile of tooth web outside is floor faying surface.
Under described upper and lower frange plate, frange plate width is greater than top flange plate width.
Described symmetry is connected to two blocks of profile of tooth webs between upper and lower frange plate, and the symmetrical introversion in its top forms trapezoid cross section steel beam with box shape with upper and lower frange plate.
The profile of tooth breach end of described profile of tooth web is connected with bottom wing listrium down.
Described top flange plate has irrigation hole.
The prefabricated profile of tooth web of the utility model steel beam with box shape is by the different frange plate up and down of width and two trapezoid cross section box beam that symmetrical profile of tooth web forms, the profile of tooth breach of its profile of tooth web arranges down, not only contribute to improve the stability of pressed flange, be convenient to the laying of preheating embedding line, and be conducive to follow-up placing of concrete and shaped steel and form the composite beam of stablizing one, girder steel is wrapped up by concrete, increased fire resistance, in addition, the design leaves floor faying surface at the bottom wing listrium of two profile of tooth web outside, easy for installation, good stability.
