Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:

As shown in Figure 1, a kind of reinforced concrete beam and girder with rolled steel section en cased in concrete connecting joint structure, it is characterized in that: comprise reinforced concrete beam and girder with rolled steel section en cased in concrete, reinforced concrete beam and girder with rolled steel section en cased in concrete are connected in profile steel concrete column by bolt-through, corresponding on reinforced concrete beam and girder with rolled steel section en cased in concrete junction, the firm bracket of I shape is respectively equipped with in the shaped steel post jamb of bottom flange, the diaphragm for sash is provided with in the profile steel concrete column of the inner side of the firm bracket of described two I shape, the two side portions of described profile steel concrete column and reinforced concrete beam and girder with rolled steel section en cased in concrete junction is provided with batten plate.

In the present embodiment, described profile steel concrete column adopts a H profile steel and two Slit T weldings to form.

In the present embodiment, described girder with rolled steel section en cased in concrete inside is run through column tie-bar.

In the present embodiment, the H profile steel sectional dimension of Nodes is 600 × 300 × 16 × 25, and T-steel cross section chi 292 × 300 × 16 × 25, beam Shaped Steel mainly selects HW450 × 200 × 9 × 14.

In the present embodiment, the connection of described beam and post all adopts the through rigid connection node of post, and steel column is corresponding to the upper and lower edge of a wing place of section steel beam, and the lower edges place of reinforced concrete beam.

In the present embodiment, described diaphragm thickness 16mm.

In the present embodiment, described diaphragm is provided with the steam vent that when being convenient to concreting, air can overflow smoothly.

In the present embodiment, 10.9 grades of torsion shear type high tensile bolts selected by described bolt.

In the present embodiment, described beam column handing-over position also adopts manual electric arc welding to weld, and welding rod adopts Golden Bridge board J506 welding rod.

The construction technology process that steel reinforced concrete beam column connects is: beam, the factory-assembled of column type steel is welded-is transported to scene-site acceptance-Welding Safety facility accessory and arranges cable wind rope-reinforced concrete column installation-installation steel column around, girder steel forms stable frame-measurement update (the other station of management)-high-strength bolt and just twists, twist (the other station of management)-post and post eventually, post welds with beam-and seam inspection detects (the other station of management)-temporary fixed otic placode and cuts off-and post indulges muscle and docks a sheathed column tie-bar-beam and indulge muscle perforation, welding-sheathed beam stirrup-beam, post tie with reinforcing bar-strutbeam, column template-cast beam, post concrete-maintenance-form removal.

Concrete in profile steel concrete column is subject to the stop of peg on post inner mold steel core post at dropping process, also be subject to the stop of sash rib and lateral tie simultaneously, make the density of casting and compacting of concrete comparatively be difficult to ensure card, thus directly affect the rigidity of node and the quality of component.

For ensureing workmanship, commercial concrete pumping should be adopted in construction to water and to smash, should note in the even blanking of steel column surrounding, vibrate watering in the process of smashing, avoid aggregate and slurries to occur segregation phenomenon, avoid the member biases because concrete side pressure inequality causes.

When building the concrete of girder with rolled steel section en cased in concrete, first should ensure the compactness of the following casting and compacting of concrete of shaped steel bottom wing listrium.Therefore should adopt and vibrate from the blanking of section steel beam side, make concrete at the bottom of bottom wing listrium, press to the opposite side of beam lentamente, exceed after the mm of bottom wing listrium face 50 until concrete height, use instead both sides double while blanking vibrate, exceed after the mm of top flange plate face 100 until concrete, then extend blanking from the span centre position of beam to both sides.This construction technology, can ensure that frange plate bottom bubble is discharged from girder steel both sides preferably.

When beam, post casting and compacting of concrete, all should note preventing at section steel flange bottom surface and formation dead angle, stiffening rib dividing plate bottom surface, and should strengthen vibrating in construction, note maintenance.

Shaft and beam body shaped steel are prefabrication, and on-the-spot welding portion mainly appears at the frange plate butt welding of cantilever beam section and middle girder section, therefore can adopt the monolateral or bilateral V-arrangement groove butt weld of band backing plate.Before welding, the dirt such as oil, water, rust clearing up groove and both sides should be noted, simultaneously attentional manipulation welding quality.

The reinforced concrete composite structure of the present embodiment, for reinforced concrete structure and steel work, has obvious advantage.Mutually retrain between type Steel concrete in component, give full play to again the own characteristic of bi-material.Shaped steel is arranged on inside concrete, enhances the ductility of component, improves the anti-seismic performance of structure; Concrete is wrapped in outside shaped steel, enhances the fire-resistant of component and endurance quality.Therefore, adopt reinforced concrete composite structure to build the building got up and there is the advantages such as bearing capacity is high, ductility good, deformability is strong.

The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
