Abstract

The utility model discloses a double-grid beam structure for reinforced concrete hollow beam and multi-ribbed beam, comprising a hollow beam formed by upper rib beams and lower rib beams connected to a shearing key; multi-ribbed beams are arranged between the upper rib beams; the multi-ribbed beams and the upper rib beams are arranged at the same height, forming a grid beam; the multi-ribbed beams are arranged above the hollow of the lower grid beam of the prime gridding encircled by the lower rib beams. Adopting a double-grid beam structure, in the case of great intensity, the utility model can greatly reduce the weight of the building structure and reduce construction cost. The prime gridding made up by the hollow beam has a various shapes and can form various beautiful gridding patterns. Additionally, the utility model has the advantages that it is small in height and occupying area, thus saving room. The utility model is particularly suitable for both mono-floor and multi-floor roof board with big span from 15 meter to 24 meter.

Description

Steel concrete laced beam and close girt strip double-grid girder construction
Technical field:
The utility model relates to a kind of steel concrete laced beam and close girt strip double-grid girder construction, belongs 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 purpose of this utility model is: provide that a kind of laced beam network is big, building costs is lower and be suitable for steel concrete laced beam and the close girt strip double-grid girder construction of span more than 15m, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: 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 utility model compared with prior art the utlity model 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 utility model 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 utility model has various ways, can form the lattice of multiple grace; In addition, the utility model also have structure height little, take the advantage that architectural space is little, save floor height.The utility model is particularly suitable for building 15m~24m wide span single layer or multilayer roof system or superstructure.
