Abstract
The utility model relates to a circular-hole web box-shaped steel reinforced concrete composite flat beam, which belongs to the field of a building component. The circular-hole web box-shaped steel reinforced concrete composite flat beam consists of a prefabricated circular-hole web box-shaped steel beam and a cast-in-place concrete layer, wherein the prefabricated circular-hole box-shaped steel beam consists of an upper flange plate, a lower flange plate and circular-hole webs, the upper flange plate is parallel to the lower flange plate, the two circular-hole webs are symmetrically arranged between the upper flange plate and the lower flange plate, the upper edge and the lower edge of each circular-hole web are respectively and fixedly connected with the upper flange plate and the lower flange plate, the lower flange plate at the outer sides of the two circular-hole webs is a floor joint surface, the box-shaped steel beam is a trapezoid-cross-section box-shaped beam consisting of the upper flange plate, the lower flange plate and two symmetric circular-hole webs in different width, the stability of the stressed flange plate can be improved and the laying of an embedded pipeline can be favored through the circular-hole webs, a stable integrated composite beam is formed by pouring the concrete and steel in the subsequent step, the lower flange plate on the outer sides of the two circular-hole webs is provided with the floor joint surface, so that installation is convenient, and the stability is good.
Description
Technical field
A kind of band circular hole of the utility model web box steel concrete composite flat beam, belongs to building unit field.
Background technology
At present, building field, generally adopts girder steel or cast-in-situ steel reinforced concrete beam, and 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 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 band circular hole web box steel concrete composite flat beam, to improve torsional property, stability, the globality of beam, and effectively increases the space that utilizes of building interlayer.
A kind of band circular hole of the utility model web box steel concrete composite flat beam, by prefabricated band circular hole web steel beam with box shape and cast-in-situ concrete layer, formed, described prefabricated band circular hole web steel beam with box shape is comprised of top flange plate, bottom wing listrium, band circular hole web, top flange plate, bottom wing listrium be arranged in parallel, two blocks of band circular hole 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 two blocks of bottom wing listriums with circular hole web outside are 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 band circular hole 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.
There is irrigation hole on described top flange plate surface.
The utility model prefabricated band circular hole web steel beam with box shape is by the different frange plate up and down of width and two trapezoid cross section box beam that symmetry forms with circular hole web, its band circular hole web is opened circular hole design, 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 increased its fire resistance by concrete parcel, in addition, the design leaves floor faying surface at two blocks of bottom wing listriums with circular hole web outside, easy for installation, good stability.
