Description
Technical field
This utility model relates to a kind of composite floor, is particularly suited in engineering field building structure the novel two-way of use
The beam of falling T composite floor.
Background technology
At present, along with country greatly develops Steel Housing Industrialization, steel house can meet buildings and resources and can hold
The requirement of supervention exhibition, is conducive to again accelerating Process of Housing Industrialization, meets the requirement that urbanization process quickly propels, meet state
Family's industrial policy, is with a wide range of applications.
For realizing the intensive of steel house and factorial praluction, accelerate steel house development, first need solve
Affect the structural system problem of steel house development, such as floor system so that it is reach standardization, seriation, mass production,
And then promote the industrialized development of steel house.
It is also proposed the floor construction of a lot of form both at home and abroad, and rapid construction for convenience, reduce the thickness of floor simultaneously
Degree, the forms using composite floor, composite flat beam floor is exactly one of which more.Composite flat beam floor is at normal steel structure house
Floor has its obvious advantage, has and reduce the feature that floor deadweight, raising headroom and apyrous are good.But traditional combination
The connection of flat its girder steel of beam floor and concrete is to realize by arranging shearing-resistant member, and shearing-resistant member complexity and can not be is set very much
Ensure well the combined effect of girder steel and concrete.And form many employings one-way slabs layout of traditional composite flat beam floor, building
Plate thickness is bigger.
Summary of the invention
For above-mentioned technical problem, proposing a kind of mechanism simple, from heavy and light, exempt to tear open bed die, bidirectional arrangements, thickness is little, whole
Body is good, reasonable stress and the novel two-way beam of the falling T composite floor of economy.
For realizing above-mentioned technical purpose, the novel two-way beam of falling T composite floor of the present utility model, it include by many fall T
The intersecting parallels component that section steel beam is constituted, the inverted T shape steel beam web plate of described intersecting parallels component has multiple aperture, inverted T shape successively
Between aperture on steel beam web plate, arranged crosswise has reinforcing bar, is provided with splicing node, multiple intersecting parallels structures at intersecting parallels Member Lip
The two-way shaped steel rib structure of stress effect is played, between the girt strip of two-way shaped steel rib structure when constituting construction by splicing node between part
Each district lattice are sequentially arranged the light-weight precast slab of the permanent template as floor, described two-way shaped steel rib structure and light-weight precast slab
On be uniformly cast with concrete.
Described splicing node is: set on the both sides between the inverted T shape girder steel of intersecting parallels component and intersecting parallels component
Having L-shaped splice plate, lower section is provided with lower flange splice plate, is fastened by bolts；Described hole diameter is bigger than the diameter of reinforcing bar；State
Concrete uniformly it is cast with, by passing the steel of aperture on inverted T shape steel beam web plate on two-way shaped steel rib structure and light-weight precast slab
Muscle carries out boning and plays the effect of shearing-resistant member, strengthens combination effect.
Beneficial effect:
(1) girder steel is embedded among concrete floor, utilizes the cohesive force between girder steel and concrete to realize both altogether
Same-action, has played the mechanical characteristic of bi-material well；
(2) use two-way flat beam form, reduce floor deadweight, floor does not has secondary beam occur, it is possible at utmost to reduce
The floor height of structure, increases and effectively uses space；
(3) concrete is that girder steel provides lateral support, it is therefore prevented that the plane instability of girder steel, the local stability of girder steel and whole
Body is stable substantially can be considered at serviceability limit stage；
(4) the two-way beam of falling T composite floor is interspersed in the web of girder steel, the most so due to the reinforcing bar of top flange concrete
Shearing resistance measure better than the method being separately provided shearing-resistant member, use simultaneously bi-directional symmetrical arrange, thus without because of horizontal stroke
Configure less to reinforcing bar and cause longitudinal splitting crack；
(5) inverted T shape girder steel is not owing to having to use the edge of a wing being generally arranged on girder steel near neutral axis, saving steel,
Thus reduce structural cost；
(6) concrete encases girder steel, improves fire prevention and the antiseptic power of girder steel, reduces in light-duty steel construction house cost and account for
Fire prevention that ratio is higher and anticorrosion expense；
(7) eliminate template minimizing die process simultaneously thus shorten construction period, there is good Technological Economy effect
Benefit；
(8) flexible arrangement of underfloor surfacing, beneficially room and freely separating, and need not do furred ceiling, it is possible to
Meet the requirement of the use function of house well.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the novel two-way beam of falling T composite floor of the present utility model uses two-way flat beam form,
Including the intersecting parallels component being made up of many inverted T shape girder steels 1, inverted T shape girder steel 1 web of described intersecting parallels component has successively
Multiple apertures 9, between the aperture 9 on inverted T shape girder steel 1 web, arranged crosswise has reinforcing bar 3, straight than reinforcing bar 3 of described aperture 9 diameter
Footpath wants big, is provided with splicing node 5 at intersecting parallels Member Lip, constitutes construction by splicing node 5 between multiple intersecting parallels components
Time play the two-way shaped steel rib structure of stress effect, as shown in Figure 4 and Figure 5, described splicing node 5 is, at intersecting parallels component and well
Both sides between the inverted T shape girder steel 1 of both font components are provided with L-shaped splice plate 6, and lower section is provided with lower flange splice plate 7, passes through
Bolt 8 fastens, and the lightweight that the girt strip Jian Ge district lattice of two-way shaped steel rib structure are sequentially arranged the permanent template as floor is prefabricated
Plate 2, described two-way shaped steel rib structure and light-weight precast slab 2 is uniformly cast with concrete 4, states two-way shaped steel rib structure and lightweight
Uniformly it is cast with concrete 4 on precoated plate 2, plays anti-by carrying out bonding through the reinforcing bar 3 of aperture 9 on inverted T shape girder steel 1 web
Cut the effect of part, strengthen combination effect.
This utility model combines the feature that two-way ribbed slab stress performance is good, and steel rib-concrete combination beam is abundant simultaneously
Play concrete and the respective performance advantage of steel, steel rib-concrete combined floor is arranged to two-way, form intensity high, just
The two-way girt strip structure that degree is big, ductility is good.The two-way girt strip skeleton being made up of inverted T shape girder steel 1 can carry the construction lotus at initial stage
Carry, and bidirectional arrangements so that two-way anti-side rigidity is consistent, the beneficially antidetonation of floor.Light-weight precast slab 2 again can be as floor
Permanent template, and smooth at the bottom of its plate, it is not necessary to do the subsequent operation such as furred ceiling, easy construction again.Reinforcing bar 3 is interspersed in inverted T shape girder steel 1
Web in, the effect of peg can be served as, improve the bond effect between concrete 4 and inverted T shape girder steel 1, be conducive to altogether
Same-action.The major part of inverted T shape girder steel 1 is wrapped up by concrete, and high degree decreases at fire prevention and the anticorrosion of inverted T shape girder steel 1
Reason.Inverted T shape girder steel 1 is spliced into entirety by L-type splice plate 6, lower flange splice plate 7 and bolt 8, and construction is succinct, simple to operate,
Greatly reduce work on the spot.
