Compared with the prior art, the composite floor system in the utility model has the advantages of light self weight, good overall performances, excellent earthquake-proof performances, small on-site construction working amount, construction convenience and short construction cycle. Furthermore, the lightweight composite floor system which generally has a relatively high anti-fire capability is suitable for relatively large spans.

Description

A kind of lightweight composite floor system
Technical field
The utility model relates to a kind of lightweight composite floor system.
Background technology
In the especially many high-level structures of building structure, adopt profiled sheet one ordinary concrete composite floor system, ordinary reinforced concrete girt strip type superstructure or steel concrete intersecting parallels superstructure etc. usually.The post that these building cover structures are difficult to adapt to large bay on the one hand has a negative impact because of the anti-seismic performance of its bigger deadweight to structure apart from requiring on the other hand.In addition, existing building cover structure is the situ wet operation mostly, and the duration also is affected.
The utility model content
The utility model technical problem to be solved be to above-mentioned prior art a kind of existing enough supporting capacitys are provided, again because of lighter weight has good seismic resistance, and easy construction, suitable lightweight composite floor system than large bay.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this lightweight composite floor system is characterized in that: comprise by the intersection truss and form substrate, the top of this substrate is provided with precast plate, and the top of precast plate is equipped with the last layer concrete.
The steel truss that intersects preferably adopts high intensity thinner tube clod wash galvanized sheet, goes up wherein that lower edge is the cold bending thin wall channel-section steel, web member is a channel bar, and integral body is positioned at the lower floor of superstructure.
Said substrate top is furnished with first connector on the upper chord of truss infall; Be furnished with second connector on the upper chord of said substrate top beyond truss intersects; Said first connector comprises two orthogonal junction plates that are crisscross arranged; Overlook after these two orthogonal being crisscross arranged of junction plate and be " ten " font, two ends of these two junction plates are provided with " U " font cover plate; Said second connector comprises that one has the bending plate of opening, thus " U " font that makes the cross section of said second connector be.
Said precast plate is arranged on the district's lattice that surrounded by said first connector and second connector.
Said last layer concrete directly is cast in said precast plate, said first connector and second connector top.
The last lower chord and the web member of said intersection truss are thin-wall channel; The connection of intersection steel truss adopts engaging lug to connect through tapping screw.
Said precast plate is made by lightweight aggregate armored concrete slab or lightweight aggregate steel concrete fiberboard, and upper surface and side are matsurface; And precast plate is supported on winding up of intersection truss and covers all the formed district of intersection steel truss lattice, is not less than 5cm with the lap length of winding up.
Said last layer concrete adopts the light weight aggregate concrete supporting, disposes the distribution bar of some in the last layer concrete.
Compared with prior art, the advantage of the utility model is:
1, compare with existing all building cover structures, good from heavy and light, overall performance and anti-seismic performance;
2, few, the easy construction of site operation workload, short construction period;
3, because of the lower support truss adopts high-strength galvanized sheet, the anti-fiery ability of the integral body of superstructure is improved.
4, applicable bigger span.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The lightweight composite floor system that the utility model provides is formed by intersecting truss 1, precast plate 2 and last layer concrete 5, and through first connector 3, second connector 4 each several part is combined into whole co-operation, referring to Fig. 1,4,5, shown in 6.The truss 1 that wherein intersects is formed the substrate of lightweight composite floor system; Precast plate 2 is supported on winding up of intersection truss 1 and covers all the formed district of intersection steel truss lattice; First connector 3 is arranged in the substrate top on the upper chord of truss infall; Arrange second connector 5 on the upper chord of substrate top beyond truss intersects, said first connector 4 comprises two orthogonal junction plates that are crisscross arranged, and overlooks after these two orthogonal being crisscross arranged of junction plate to be " ten " font; Two ends of these two junction plates are provided with " U " font cover plate, referring to shown in Figure 2; Said second connector 5 comprises that one has the bending plate of opening, thus " U " font that makes the cross section of said second connector be, referring to shown in Figure 3.Last layer concrete 5 directly is cast in said precast plate, said first connector and second connector top.
In the present embodiment, the last lower chord and the web member of intersection truss 1 are thin-wall channel, are positioned at the lower floor of superstructure; The connection of intersection steel truss can adopt engaging lug to pass through the tapping screw connection, but a direction is elongated as far as possible.Steel truss cross dimensions, spacing etc. are confirmed according to the designing requirement of superstructure; Precast plate 2 is made by light weight aggregate concrete, and upper surface and side should be matsurface, with the conjugation of raising with back pouring concrete 5; Precast plate 2 is supported on winding up of intersection truss and covers all the formed district of intersection steel truss lattice, is not less than 5cm with the lap length of winding up; Precast plate 2 can be lightweight aggregate armored concrete slab or lightweight aggregate steel concrete fiberboard, and its thickness should be confirmed according to the spacing of steel truss, and should satisfy the deformation requirements in the work progress; Last layer concrete 5 is the light weight aggregate concrete of building in precast plate and steel truss top, and should guarantee the concrete density in notch place.For prevent to shrink, thermal cracking and from the stressed angle of superstructure, last layer concrete 5 planted agents dispose the distribution bar of some.
The working procedure of the utility model is:
(1) makes steel intersection truss in factory process, and connect first connector 3 and second connector 4 with tapping screw through engaging lug;
(2) at factory process precast plate 2;
(3) the on-the-spot intersection steel truss 1 of installing wherein adopts engaging lug to connect through tapping screw between the steel truss;
(4) behind intersection steel truss 1 installation in position, precast plate 2 is installed;
(5) install precast plate 2 after, lay colligation last layer reinforcing bar and also build last layer concrete 5.
