Abstract
The utility model discloses a steel beam, it includes along last pterygoid lamina (1), lower pterygoid lamina (2) and web (3) that the girder steel extending direction extends, go up pterygoid lamina (1) and be on a parallel with pterygoid lamina (2) down, go up pterygoid lamina (1) with pterygoid lamina (2) are through two down web (3) are connected, two web (3) are parallel to each other, it is located just directly over pterygoid lamina (2) down to go up pterygoid lamina (1) the width is less than down the width of pterygoid lamina (2). The utility model discloses a girder steel is favorable to reducing the height of precast floor for precast floor and girder steel are located roughly same level, avoid the girder steel obviously to stand out to the indoor usage space in.
Description
Technical Field
The utility model relates to a girder steel belongs to building technical field, especially relates to assembly type structure technical field.
Background
In the field of prefabricated building technology, beams are usually reinforced concrete beams, and prefabricated floor slabs are placed on the reinforced concrete beams. However, this approach has problems: the height of the prefabricated floor slab is obviously higher than that of the reinforced concrete beam, and accordingly the beam protrudes in the indoor use space, so that the use space and the attractiveness are influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that exists among the prior art, the utility model provides a girder steel can suitably reduce the height of precast floor for precast floor and girder steel roughly are located same horizontal plane, can not make the girder steel obviously outstanding in indoor usage space. The specific technical scheme is as follows.
A steel beam, its characterized in that: include along last pterygoid lamina, lower pterygoid lamina and the web that the girder steel extending direction extends, go up the pterygoid lamina and be on a parallel with lower pterygoid lamina, go up the pterygoid lamina with lower pterygoid lamina passes through two the web is connected, two the web is parallel to each other, go up the pterygoid lamina and be located under just the pterygoid lamina the width of going up the pterygoid lamina is less than the width of pterygoid lamina down.
By adopting the technical scheme, when the precast floor slab is hoisted, the precast floor slab can not interfere with the upper wing plate in the falling process, and the end part of the precast floor slab can be directly placed on the lower wing plate of the steel beam instead of the upper wing plate, so that the steel beam and the precast floor slab can be approximately at the same horizontal height, and the technical problem that the precast floor slab is obviously higher than the beam is avoided.
Furthermore, the upper wing plate and the two webs are integrally formed, and the cross section of a structure formed by the upper wing plate and the two webs together is in an inverted U shape. For example, the upper wing plate and the two webs are bent by a steel plate to form an inverted U shape. The advantages of this arrangement are: on the one hand, the number of welding joints is reduced, only two welding joints for connecting the web plate and the lower wing plate exist, and on the other hand, the structural strength, especially the bending resistance, of the whole steel beam is improved.
Furthermore, the steel beam further comprises a stiffening plate positioned on the outer side of the web plate, the stiffening plate is perpendicular to the extending direction of the steel beam, and the stiffening plate is fixedly connected with the lower wing plate and the web plate. The stiffening plate is favorable for enhancing the overall strength of the steel beam and improving the stability and reliability of the steel beam.
The utility model discloses a girder steel is favorable to reducing the height of precast floor, directly utilizes the lower pterygoid lamina to support precast floor for precast floor and girder steel are located roughly same level, avoid the girder steel obviously outstanding to the indoor usage space in.
Drawings
Figure 1 is the schematic diagram of the girder steel of the utility model discloses the implementation.
In the figure: the structure comprises an upper wing plate 1, a lower wing plate 2, a web plate 3 and a stiffening plate 4.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a steel beam, it includes upper wing plate 1, lower wing plate 2 and web 3 that extend along the steel beam extending direction, and upper wing plate 1 is on a parallel with lower wing plate 2, and upper wing plate 1 and lower wing plate 2 connect through two webs 3, and two webs 3 are parallel to each other, and upper wing plate 1 is located directly over lower wing plate 2 and the width of upper wing plate 1 is less than the width of lower wing plate 2.
Preferably, the upper wing plate 1 and the two webs 3 are integrally formed, and the cross section of the structure formed by the upper wing plate 1 and the two webs 3 is in an inverted U shape. For example, the upper wing plate 1 and the two webs 3 are bent from a steel plate to form an inverted U-shape. The advantages of this arrangement are: on the one hand, the number of welding seams is reduced, only two welding seams for connecting the web 3 and the lower wing plate 2 exist, and on the other hand, the structural strength of the whole steel beam is improved, and particularly, the bending resistance is improved.
Preferably, the steel beam further comprises a stiffening plate 4 positioned at the outer side of the web 3, the stiffening plate 4 is perpendicular to the extending direction of the steel beam, and the stiffening plate 4 is fixedly connected with the lower wing plate 2 and the web 3. The stiffening plates 4 are beneficial to enhancing the overall strength of the steel beam and improving the stability and reliability of the steel beam.
By adopting the technical scheme, when the precast floor slab is hoisted, the precast floor slab can not interfere with the upper wing plate 1 in the falling process, the end part of the precast floor slab can be directly placed on the lower wing plate 2 of the steel beam instead of the upper wing plate 1, so that the steel beam and the precast floor slab can be approximately at the same horizontal height, and the technical problem that the precast floor slab is obviously higher than the beam is solved.
The embodiments of the present invention have been described above with reference to the accompanying drawings, and features of the embodiments and examples of the present invention may be combined with each other without conflict. The present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and the scope of the present invention, which is encompassed by the present invention.
