Abstract
The utility model relates to a double-layer large-span girder hanging type lower layer girder structure which comprises an upper layer girder connected with a lower layer girder through a plurality of sets of vertical connecting structures arranged at intervals, and the vertical connecting structures enable the two layers of girders to be connected into a whole. The vertical connecting structures are columns or walls. The two layers of girders are connected into a whole through the vertical connecting structures, the double-layer large-span girder hanging type lower layer girder structure can achieve joint load-bearing and joint action, and an integral stress structure is formed to jointly bear load. Due to the fact that the span of the lower layer girder is effectively reduced, the section height of each girder is reduced, and the load-bearing requirements of using functions and the requirements for reinforcing vertical and transverse rigidity of the structure are met.
Description
Technical field
The utility model relates to a kind of double-deck long-span beams structure, belongs to the building girder technical field of structures.
Background technology
In recent years, the building of many public buildings, particularly culture, commerce, sport category, often requirement is higher aspect the space, thereby the span of beam is also just larger.Such as library, cinema, Basketball hall etc., in these buildings, because specific (special) requirements such as the positions such as mechanical floor, theater entablature beam of horizontal planning of building and use function often will arrange double-deck long-span beams.At present, mainly adopt twice to construct equally prestressed girder or the girder with rolled steel section en cased in concrete of design, the upper strata beam is owing to bear all kinds of primary loads, often dead load is large, and beam and bean column node place reinforcing bar are intensive, and deck-molding is higher, cost is high, and lower floor's beam is mainly born secondary load, and structural requirement is lower, but in existing design, because span is larger, for reducing amount of deflection, often also adopt the form of structure same with the upper strata beam, cause waste, and deck-molding is higher, has compressed effective usage space.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of double-deck long-span beams suspension type lower floor girder construction is provided.
The technical scheme that the utility model is taked is:
Bilayer long-span beams suspension type lower floor girder construction comprises the upper strata beam, the vertical connection structures connection lower floor beam that the upper strata beam arranges by many groups interval, and vertical connection structure connects two-layer beam in aggregates.
Described vertical connection structure is post or wall, is cast in upper strata beam, lower floor's beam by reinforced frame.
Connect two-layer beam in aggregates by vertical connection structure, structure is carried jointly, acting in conjunction, form a whole force structure, common bearing load, and owing to effectively reduce the span of lower floor's beam, thereby reduce its depth of section, namely satisfy the load bearing requirements of using function and reach again in length and breadth rigidity requirement of reinforcement structure.
The beneficial effect that the utility model has compared with prior art:
One, double-deck large span suspension type lower floor beam is compared with general double-deck long-span beams, increases usage space, reduces story height, reduces cost and construction costs, increases economic efficiency.
Two, the beam construction of suspension type lower floor is compared with the general double-deck long-span beams structure that arranges: stressed comparatively reasonable, and the integral body that strengthens structure rigidity in length and breadth, be conducive to the antidetonation of structure.
Three, this structure stress is reasonable, saves reinforcing bar and concrete amount, reduce project cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1, upper strata beam, 2, lower floor's beam, 3, vertical connection structure.
The specific embodiment
Below in conjunction with accompanying drawing this practical patent is elaborated:
Below the present invention is described in further detail.
Bilayer long-span beams suspension type lower floor girder construction comprises upper strata beam 1, the vertical connection structures 3 connection lower floor beams 2 that upper strata beam 1 arranges by many groups interval, and vertical connection structure 3 connects two-layer beam in aggregates.Vertical connection structure is post or wall.
Build order is as follows: the lower beam bottom mold mounting → upper girder erection of scaffold erection gluten → upper beam gluten and hanging bars (closed hoop) beam stirrups lower beam steel banding banding → → lower beam outside the lower slab mold template installation → Installation → Lower House surface steel banding → lower floor concreting → Maintenance → → vertical elastic line connection structure (walls and columns) → vertical banding horizontal bar connecting structure (walls and columns) of concrete pouring → upper beam bottom mold mounting → upper beam bottom reinforcement , lumbar muscle banding, hanging hoop (closed hoop) welding → install → upper upper slab mold layout and slab prestressed concrete pouring steel banding → → Maintenance → upper slab mold removal → vertical connection structure (walls and columns) → lower slab mold removal removed.
