Abstract
The utility model provides a combined steel reinforced concrete composite beam, and belongs to the field of building structures. The design is composed of a combined profile steel skeleton, a prefabricated combined profile steel skeleton concrete beam and a cast-in-place steel reinforced concrete beam, wherein the combined profile steel of the combined steel skeleton is composed of an upper square steel pipe, a lower steel angle and U-shaped steel connecting to the two sides thereof, reinforcing steel bars are symmetrically arranged at the two sides of the lower part of the combined profile steel and are hooped to a lower steel-reinforcing steel bar cage through transverse reinforcing steel bar hoops; the two ends of the combined profile steel and the reinforcing steel bars are respectively connected with the end heads of the profile steel; concrete is cast in the lower steel-reinforcing steel bar cage and the square steel pipe to form the prefabricated combined profile steel skeleton concrete beam; on site, an upper steel reinforced concrete beam is cast in place along the square steel pipe and the U-shaped steel to form the composite beam, in the design, the U-shaped steel provides larger anti-shear and anti-torsion capacity and reduces construction stage support, no reinforcing steel bar is arranged in the cast-in-place steel reinforced concrete beam, so that the making procedure is reduced, and the carrying capacity demands of the beam body at the construction and application stages are satisfied.
Description
Technical field
A kind of combined type steel reinforced concrete of the utility model compound beam, belongs to building structure field.
Background technology
Steel-mixed combining structure is steel work coefficient structural system together with reinforced concrete structure, conventional combining structure multiplex simple H shaped steel or box steel etc., although this structure is made simple, but stressed unintelligible during for iterative structure, can not meet the loading characteristic of construction stage and operational phase simultaneously; And the concrete that conventionally combining structure is used mostly is armored concrete, although armored concrete can operative constraint shaped steel and concrete acting in conjunction, mostly assembling reinforcement is to adopt artificial colligation, and production efficiency is low, is unfavorable for the production of millwork streamlined.
Utility model content
The purpose of this utility model is to provide a kind of combined type steel reinforced concrete compound beam, and raising superposed beam, at the bearing capacity of construction stage, reduces construction stage support and sets up, and give the bearing capacity and stiffness that compound beam is larger, builds headroom by reducing deck-molding increase.
The utility model is achieved through the following technical solutions:
A kind of combined type steel reinforced concrete of the utility model compound beam, by combined steel frame, Prefabricated composite type steel skeleton concrete beam and cast-in-place girder with rolled steel section en cased in concrete composition, described combined steel frame is by combining shaped steel and reinforcing bar forms; Described combination shaped steel is made up of square steel pipe, angle steel and U-shaped steel, and square steel pipe is arranged on top, and two angle steel correspondences are arranged on square steel pipe below, and the symmetrical interval of U-shaped steel is connected between top square steel pipe and angle steel both sides, bottom; Reinforcing bar is arranged symmetrically in combination both sides, shaped steel bottom, and by spaced transverse reinforcement hoop, hoop is connected into type bottom shaped steel-reinforcing cage; Combination shaped steel is connected with shaped steel termination respectively with reinforcing bar two ends; Along concreting in bottom shaped steel-reinforcing cage and square steel pipe, be formed with the Prefabricated composite type steel skeleton concrete beam of symmetrical overlap joint platform; At the construction field (site), take and put after precast floor slab at moulding prefabricated combined steel frame concrete beam overlap joint platform, along square steel pipe and U-shaped steel, cast-in-place type steel reinforced concrete top beam, moulding compound beam.
The square steel pipe upper surface of described combination shaped steel is provided with pouring hole.
The square steel pipe upper surface of described combination shaped steel is provided with peg.
A kind of combined type steel reinforced concrete of the utility model compound beam, square steel pipe just watered and has concrete in advance in the prefabricated stage, therefore remarkable in its resistance to compression effect of construction stage, Prefabricated composite type steel skeleton concrete beam reinforcing and angle steel bearing tension, reasonable stress, reduces the on-the-spot use of supporting; Spaced apart U-shaped steel can provide larger shearing resistance, anti-twisting property, reduces the construction stage and supports use, in its cast-in-place girder with rolled steel section en cased in concrete, has shaped steel bone, do not establish reinforcing bar, reduce reinforcing bar binding, reduction production process, the utility model meets the requirement for bearing capacity of beam body in construction and operational phase.

Detailed description of the invention
Now further illustrate by reference to the accompanying drawings implementation process of the present utility model:
A kind of combined type steel reinforced concrete of the utility model compound beam, by combined steel frame, Prefabricated composite type steel skeleton concrete beam and cast-in-place girder with rolled steel section en cased in concrete composition, described combined steel frame is by combining shaped steel and reinforcing bar forms; Described combination shaped steel is made up of elongated square steel pipe, angle steel and U-shaped steel, and elongated square steel pipe 4-1 is arranged on top, and two elongated angle steel 4-2 correspondences are arranged on square steel pipe below, and U-shaped steel 4-3 is symmetrical, and interval is connected to top square steel pipe and angle steel both sides, bottom; Reinforcing bar 5-1 is arranged symmetrically in combination both sides, shaped steel bottom, and by spaced transverse reinforcement hoop 5-2, hoop is connected into bottom shaped steel-reinforcing cage; Combination shaped steel is connected with shaped steel termination 6 respectively with reinforcing bar two ends; Along bottom shaped steel-reinforcing cage concreting, be formed with the Prefabricated composite type steel skeleton concrete beam 1 of symmetrical overlap joint platform P in combined steel frame bottom, meanwhile, by square steel pipe 4-1 upper surface pouring hole A to placing of concrete in square steel pipe; At the construction field (site), take and put after precast floor slab at the overlap joint platform P of moulding prefabricated combined steel frame concrete beam 1, along square steel pipe 4-1 and the cast-in-place top of U-shaped steel 4-3, both sides type steel framed concrete beam 2, moulding compound beam.
Described square steel pipe upper surface is provided with surface and is welded with peg 4-4.
