Abstract
A method for constructing the roof of large-span building includes such steps as in-situ casting the lower ribbed beams and shear keys in large lattice mode, putting the ribbed ferroconcrete slabs on the shear keys to form rib slots between said slabs and lower ribbed beams, binding reinforcing bars in the rib slots, in-situ casting concrete, and curing. Its advantages are low cost, beautiful lattice pattern, and less possesses building space.
Description
Technical field:
The present invention relates to the building method and the double-grid girder construction thereof of a kind of long span building thing roof system or superstructure, belong to technical field of buildings.
Background technology:
At present, when building long span building roof system or superstructure, in order to make full use of building space, generally all adopt the laced beam structure in the prior art, help in laced beam, arranging pipeline like this, thereby reduce the floor height of building greatly, the grid that this laced beam of the prior art is formed is the square net of orthogonal spatial, the square net of this orthogonal spatial forms the quadrature same sex waffle slab that structure height equates everywhere, this quadrature same sex waffle slab can equivalence be " sandwich slab " on mechanical calculation, the shortcoming of the laced beam structure that the square net of this orthogonal spatial of the prior art is formed is: grid is closeer, the formed square net size of its laced beam is generally about 1.5m * 1.5m, therefore required constructional materials is more, building costs is higher, not too be suitable for span more than 15m the long span building roof system or the building of superstructure.
Summary of the invention:
The objective of the invention is: provide that a kind of laced beam network is big, building costs is lower and be suitable for the long span building thing roof system of span more than 15m or the building method and the double-grid girder construction thereof of superstructure, to overcome the deficiencies in the prior art.
The present invention is achieved in that the building method of long span building thing roof system of the present invention or superstructure is: it comprises adopts the steel concrete ribbed plate, when the roof system of building wide span single layer or tier building with reinforced concrete cast-in-situ or superstructure, it is earlier cast-in-place that to go out the bottom be macroreticular girt strip and shear connector down, shelve the steel concrete ribbed plate then in shear connector top, make between the both sides of the chest of steel concrete ribbed plate above the macroreticular girt strip down and macroreticular down between the girt strip above form the rib groove, reinforcing bar in the groove on the bundle, and with reinforcing bar anchor in the shear connector in corresponding rib groove, in the rib groove, carry out secondary cast-in-situ concrete then, after maintenance, promptly get roof system or superstructure with steel concrete laced beam and close girt strip double-grid girder construction.
Laced beam of the present invention and close girt strip double-grid girder construction are: it is included in and is connected with girt strip (2) and the formed laced beam of following girt strip (3) on the shear connector (1), between last girt strip (2), also be provided with close girt strip (4), close girt strip (4) is located at sustained height with last girt strip (2) and forms upward grid beams, and close girt strip (4) is located at down the macroreticular hollow top position of grid beams down that girt strip (3) is surrounded; The mesh shape of the last grid beams of being made up of last girt strip (2) and close girt strip (4) is little triangular mesh shape, and the mesh shape of the following grid beams of being made up of girt strip (3) down is big hexagon, trapezoidal greatly, triangular mesh shape; The mesh shape of the last grid beams of being made up of last girt strip (2) and close girt strip (4) is little square net shape, and the mesh shape of the following grid beams of being made up of girt strip (3) down is big hexagon, trapezoidal greatly, triangular mesh shape; The mesh shape of the last grid beams of being made up of last girt strip (2) and close girt strip (4) is little square net shape, and the mesh shape of the following grid beams of being made up of girt strip (3) down is big square net shape.
Owing to adopted technique scheme, the present invention compared with prior art, the present invention has the advantage that the laced beam network is big, building costs is lower.The comparable quadrature side of the prior art of the square net size size of mesh opening of upward girt strip (2) of the present invention and the formed laced beam of following girt strip (3) is big 2～5 times, and owing to adopted the structure of double lattice, therefore have under the situation of higher-strength, can alleviate building structure weight significantly, reduce building costs; And the formed macrolattice shape of laced beam of the present invention has various ways, can form the lattice of multiple grace; In addition, the present invention also have structure height little, take the advantage that architectural space is little, save floor height.The present invention is particularly suitable for building 15m～24m wide span single layer or multilayer roof system or superstructure.
