Abstract
The utility model discloses an orthogonal space mesh steel bar concrete canonical laminated meshed cylindrical shell and barrel arch roof system, which is formed from the steel bar concrete canonical laminated board (1) which bends in a circular curve or parabola shape and single way. Compared with the prior art, the structure has little obversion thickness, which is 30 percent to 50 percent less than that of the meshed cylindrical shell and meshed barrel arch structure of conventional solid cross sections and the weight of the structure is 30 percent to 50 percent lighter, having advantages of small amount of concrete consumption, low manufacturing cost, durability, anti-rust, good fire proof performance, low maintenance cost, simple construction technology and fast construction process.
Description
Technical field:
The utility model relates to a kind of roof structure of building, and it is a kind of orthogonal spatial fabricated bar concrete hollow sandwich mesh barrel shell and arched roof of zero Gaussian curvature (K=0).
Background technology:
Netted barrel shell of steel bar concrete and netted arched roof structure are a kind of can the coverings than large span, zero Gaussian curvature space net shell and net arch structure that stress performance is good.This structure has been successfully applied in 70～eighties of last century that large span is public builds with industry
Build, (" experimental room, ocean " roof system of roof system of 42m * 60m) and Hangzhou is steel bar concrete solid section three-dimensional and intersects netted barrel shell or the netted tube arch structure of forming in the Tongji University's " students' dining hall " that builds up as the phase beginning of the seventies in last century.The roof system of the solid steel bar concrete of this employing, the concrete converting thickness is bigger than normal to be its weak point, makes the deadweight of whole roof system bigger than normal, the concrete consumption is big, because deadweight is heavier, on the bigger roof system of span, is difficult to use, and when construction, because all members need the scene to water
System, the construction technology complexity, construction speed is slow.The early 21st century adopts the steel screen and the netted steel cylinder arch structure of zero Gaussian curvature of steel work, and application is arranged also the time in public and industrial construction, but the steel using amount of steel screen and netted steel cylinder arch structure is big, cost is higher, and durability, antirust, fireproof performance is relatively poor, maintenance cost is higher.
Summary of the invention:
The purpose of this utility model is: provide a kind of from heavy and light, steel using amount is little, construction is simple, construction speed is fast, manufacturing and low orthogonal spatial fabricated bar concrete hollow sandwich mesh barrel shell and the arched roof of maintenance cost, thereby overcome the deficiencies in the prior art.
The utility model is to constitute like this: it is circular curve by steel bar concrete open-spandrel sandwich board (1) or the parabolic shape bend in one direction forms.
Steel bar concrete open-spandrel sandwich board (1) is made of last rib grid (2) and following rib grid (3), last rib grid (2) is spliced into latticed by at least 4 precast plates with ribbing (4) quadrature, following rib grid (3) becomes latticed by the following rib single beam (5) of in-situ casting with following rib linear beam (6) quadrature, and last rib grid (2) is connected with the shear connector (7) of following rib grid (3) by in-situ casting.
Precast plate with ribbing (4) is shelved on the cap at shear connector (7) top, and is fixed on the shear connector (7) by the steel bar concrete (8) of second pouring.
The bottom of shear connector (7) is positioned on the crosspoint of following rib single beam (5) and following rib linear beam (6).
Precast plate with ribbing (4) is square, and the size of every precast plate with ribbing (4) is consistent.
The width of precast plate with ribbing (4) is consistent with the width of following rib grid (3).
Compared with prior art, because the utility model adopts the steel bar concrete open-spandrel sandwich board to form through bend in one direction, its structure converting thickness is little, converting thickness than the netted barrel shell of general solid section and netted tube arch structure is little by 30%～50%, thereby the corresponding decline 30%～50% of dead load, the concrete consumption reduces; And owing to dead load reduces, when having the good mechanical characteristic, the also corresponding minimizing of structural steel amount, the corresponding reduction of cost of manufacture; And durability of the present utility model, antirust, fire line all are better than steel screen and netted steel cylinder arch structure, and maintenance cost is low; The utility model only need be cast rib grid and shear connector down at the scene when construction, the precast plate with ribbing of last rib grid can simultaneously or shift to an earlier date at produce in factory, instantly after rib grid and shear connector reach certain intensity, directly precast plate with ribbing is shelved on the shear connector, it is promptly plastic after arrangement of reinforcement, secondary are cast, not only construction speed is fast, and construction technology is simple.

The specific embodiment:
Embodiment of the present utility model: as shown in Figure 3, steel bar concrete open-spandrel sandwich board 1 is pressed circular curve or parabolic shape bend in one direction, can obtain zero Gaussian curvature orthogonal spatial fabricated bar concrete hollow sandwich mesh barrel shell and arched roof of the present utility model.The structure of steel bar concrete open-spandrel sandwich board 1 as shown in Figure 1 and Figure 2, it is made of last rib grid 2 and following rib grid 3, rib grid 2 is spliced into latticed by 4 precast plate 4 quadratures with ribbing on each; Make and construction for convenient, precast plate 4 with ribbing is square, and the size of every precast plate 4 with ribbing is consistent; The size of precast plate 4 with ribbing and number needs back are as calculated determined, when calculating, whole roof system can be divided some grids at direction of a curve by arc length, divide some grids at longitudinal direction along straight line, the grid sum that obtains is exactly the quantity of required precast plate with ribbing 4, and the size of grid is exactly the size of precast plate 4 with ribbing; Following rib grid 3 becomes latticed by the following rib single beam 5 of in-situ casting with following rib linear beam 6 quadratures, and four angles in crosspoint are 90 degree, and rib grid 3 also is 90 degree with the post of supporting roof system or the crossing angle of Vierendeel girder down, i.e. " orthogonal spatial ".Last rib grid 2 is connected with the shear connector 7 of following rib grid 3 by in-situ casting, and the bottom of shear connector 7 is positioned on the crosspoint of following rib single beam 5 and following rib linear beam 6; Precast plate 4 with ribbing is shelved on the cap at shear connector 7 tops, and its width is consistent with the width of following rib grid 3.The rib of precast plate 4 with ribbing promptly is a side template of going up rib grid 2, at shear connector 7 tops four jiaos shelve square precast plate with ribbing 4 after, assembling reinforcement by second pouring steel bar concrete 8, can be fixed on precast plate 4 with ribbing on the shear connector 7.
