Abstract
The utility model provides a prefabricated cladding steel-concrete composite beam who combines together with cast-in-place, including H shaped steel roof beam, wherein one side cavity packing of the both sides cavity of H shaped steel roof beam has prefabricated reinforced concrete, and the opposite side is equipped with first connecting piece, the top of H shaped steel roof beam is equipped with the second connecting piece, the utility model provides a H shaped steel web unilateral cladding concrete prefabricated composite beam that the wholeness is good.
Description
Technical Field
The utility model relates to the technical field of building, specifically be a cladding steel-concrete composite beam that prefabricated and cast-in-place combined together.
Background
In recent years, in fabricated buildings, partially-coated steel-concrete composite columns and beams (PEC columns and PEC beams) are gradually applied to engineering, and design, processing and installation technologies are gradually improved. But still have certain problem in the application, the correlation technique is to be perfect, and traditional building often has the line foot in every layer, and the full length can be realized by aluminum plate, GRC or cast in situ concrete. However, when the PEC beam is manufactured, concrete is poured on both sides of the H-shaped steel beam in a factory, and concrete pins are poured on the side surfaces of the H-shaped steel beam in situ, integrity and pouring quality of the concrete pins cannot be guaranteed to the best.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a prefabricated combination beam of H shaped steel web unilateral cladding concrete that the wholeness is good has solved the problem that proposes in the above-mentioned background art.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a precast and cast-in-place combined clad steel-concrete combined beam comprises an H-shaped steel beam, wherein a cavity on one side of cavities on two sides of the H-shaped steel beam is filled with precast concrete, a first connecting piece is arranged on the other side of the H-shaped steel beam, and a second connecting piece is arranged at the top of the H-shaped steel beam.
Further, the first connecting piece is a web bolt or a steel bar.
Further, the second connecting piece is a floor stud.
(III) advantageous effects
To sum up, the utility model discloses the shaping can once be pour to the H shaped steel roof beam when site operation, need not the upset secondary and pour, has reduced manufacturing cost, utilizes H shaped steel roof beam one side hollow simultaneously can with concrete stitch and concrete floor monolithic casting shaping through first connecting piece, wholeness and intensity improve greatly to whole quality of construction has been improved.

Detailed Description
An embodiment of a clad steel-concrete composite beam combining prefabrication and cast-in-place according to the present invention will be further described with reference to fig. 1 to 4.
A precast and cast-in-place combined clad steel-concrete combined beam comprises an H-shaped steel beam 1, wherein a cavity on one side of cavities on two sides of the H-shaped steel beam 1 is filled with precast concrete 2, a first connecting piece is arranged on the other side of the H-shaped steel beam, and a second connecting piece is arranged at the top of the H-shaped steel beam 1.
In the embodiment, the precast concrete 2 on one side of the H-shaped steel beam 1 is precast in a factory, during site construction, the H-shaped steel beam 1 is transported to the installation position and integrally cast with the reinforced concrete wire feet 7 and the reinforced concrete floor slab 6, so that the H-shaped steel beam 1 is cast and formed at one time during site construction without turning over and secondary casting, the manufacturing cost is reduced, meanwhile, the H-shaped steel beam 1 can be integrally cast and formed with the reinforced concrete wire feet 7 and the reinforced concrete floor slab 6 through the hollow part on one side of the H-shaped steel beam 1 through the first connecting piece, the integrity and the strength are greatly improved, and the integral construction quality is improved.
Example 1: the first connecting piece is a web bolt 4, as shown in fig. 1, the web bolt 4 can be used as the connecting piece, and the specific connecting construction mode is the same as above.
Example 2: the first connecting piece is a steel bar 3, as shown in fig. 2, the steel bar 3 can be used as the connecting piece, and the concrete connecting construction mode is the same as that described above.
In this embodiment, the floor studs 5 may be used as the second connecting members, and the specific connection construction method is the same as above.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
