Abstract

The utility model provides a novel connection structure of steel construction house floor and girder steel mainly includes concrete floor, reinforcing bar, H shaped steel, concrete trabecula. For the wholeness ability that improves the total, concrete floor carries on cast -in -placely on the upper portion of girder steel, reinforcing bar and the contact segment between the shaped steel among the concrete floor adopt the welded mode, embedding reinforced concrete trabecula between two steel beam web plate, reinforcing bar in the concrete trabecula also adopts the welding with the position of shaped steel contact, compare with traditional constructed way, the intensity and the stability of girder steel and floor improve to some extent, it is more simple and convenient to be under construction, the span centre amount of deflection diminishes, the overall structure performance is more superior.

Description

The syndeton of a kind of new steel structure residence floorslab and girder steel
Technical field
The utility model relates to the syndeton of a kind of new steel structure residence floorslab and girder steel, and it is high that it has intensity, and monolithic stability is good, the simple advantage of constructing. Belong to field of civil engineering.
Background technology
The syndeton of current steel house floor and girder steel has two kinds of conventional ways: the one, on the certain altitude of steel beam web plate, weld angle steel as bracket, lay and weld certain thickness profiled sheet thereon as permanent formwork, top casting concrete, finally forms overall floor; The 2nd, embed small-sized reinforced beam one at the lateral grooves place of i-shaped beams, concrete girder forms combination beam and whole watering together with floor construction with former girder steel. The intratrabecular longitudinal reinforcement of concrete and stirrup can with floor distributing reinforcement uniform specification, avoid specification too much, increase purchase cost. The intratrabecular stirrup of concrete is connected with girder steel spot welding, floor distribution bar inserts in concrete girder, girder steel top is arranged some shear reinforcements along beam length direction at interval of 250 ~ 300mm left and right, to increase the overall anti-seismic performance of floor, one end of shear reinforcement and the welding of girder steel top flange plate, stretch in floor under the other end is oblique.
In traditional way one, need profiled sheet, although steel plate can be brought into play very large effect, cost is high, and the consumption of angle steel is also not little. From the globality of structure, do not give full play to the globality effect of girder steel.
In traditional way two, the intratrabecular stirrup of concrete is connected with girder steel spot welding, and welding capacity is large, and cost is high, the concrete girder at I-beam lateral grooves place, and assembling reinforcement is loaded down with trivial details, builds inconvenience, constructional difficulties.
Summary of the invention
In order to overcome constructional difficulties in traditional method, long in time limit, cost is high, and structural strength and integral rigidity such as can not be guaranteed at the shortcoming. The utility model provides that a kind of connecting piece structure is simple, the concrete floor of stabilized structure and the syndeton of girder steel, to address the above problem.
The utility model solves the technical scheme that its technical problem adopts: above steel girder frame structure, lay reinforcing bar, the junction of reinforcing bar and girder steel adopts the mode of welding, according to the reinforcing bar of common way colligation concrete girder, roughly the same on the specification of reinforcing bar and floor, and ride over respectively on the flange plate of two ends girder steel, adopt the mode of welding for the position contacting with H shaped steel, between concrete floor, girder steel and shaped steel, reinforcing bar adopts welding, connect closely, effectively raise bulk strength and rigidity. While setting up template, for the position that has concrete girder, template will be close to the lower surface of girder steel lower flange; And for the part that there is no concrete girder, the lower surface of the girder steel top flange that template need be close to, after one-piece casting concrete, not only can improve overall stability like this, also can be reinforcing bar and generate protective layer, easy construction is efficient, has shortened greatly the duration.
The beneficial effects of the utility model are that, by the integral cast-in-situ of concrete girder, reinforced concrete floor and girder steel, the enforcement of welding manner between girder steel and reinforcing bar, has improved intensity and integral rigidity; Do not use profiled sheet, provide cost savings; The loaded down with trivial details construction technologies such as assembling reinforcement in girder steel groove, casting concrete are saved.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Fig. 1 is the profile of girder steel of the present utility model and concrete floor junction.
Fig. 2 is the layout design sketch of concrete girder.
Fig. 3 is girder steel, concrete floor and concrete girder whole structure figure.
1. floor steel bar stresses in figure, 2. concrete girder negative reinforcement and girder steel weld, 3. floor steel bar stress and girder steel welding, 4. concrete floor, 5. floor distribution bar, 6. floor steel bar stress, 7. stirrup, 8. concrete girder steel bar stress, 9.H section steel beam, 10. concrete steel bar stress and shaped steel weld, 11 concrete girders.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
In Fig. 1 floor steel bar stress (1) (6), floor distribution bar (5), be laid on H section steel beam (9), between them, adopt the mode of welding (3), the two ends of concrete girder (11) ride on the bottom wing listrium of H section steel beam (9) as shown in Figure 2, concrete girder negative reinforcement and steel bar stress (8) adopt the mode of welding (2) (10), in addition, on concrete girder (11), stirrup (7) is also set.
The syndeton of a kind of new steel structure residence floorslab of this invention and girder steel, its concrete implementation step is as follows.
(1), between every two H section steel beam webs, set up concrete girder bar frame.
(2), concrete girder bar frame is welded with the position that H shaped steel is connected.
(3), lay the bar frame of concrete floor on the top of H section steel beam.
(4) the position welding that, the bar frame of concrete floor contacts with H section steel beam.
(5), have a place that concrete girder is set, set up concrete blinding at the lower surface of the bottom wing listrium of H section steel beam; The place of concrete girder is not set, establishes concrete blinding at the lower surface of the top flange plate of H section steel beam.
(6), carry out building of monolithic concrete.
