The upper open end of each V-arrangement connector is connected with last square tube, and the following blind end of each V-arrangement connector inserts between two vertical wing plates of two following angle steel and the three is connected;
Each arch sheet load is connected between two inboards recessed of per two adjacent truss lower ends;
Tectal upside surpasses square tube on the level of each truss.
Like this, make the simple and reasonable of this roofing.
Said each truss comprises square tube on the level, plurality of vertical V-arrangement connector, be in the square tube below and parallel with last square tube one under stretch horizontal sword shape angle steel;
Two inclination wing plates of sword shape angle steel stretch out and symmetric arrangement; Two inclination wing plates of sword shape angle steel and vertically have a angle acute angle between the wing plate and uncovered up recessed; So that each truss lower end has inside and outside two of arranging recessed; And for per two adjacent truss; In setting the recessed sides of two of a truss lower end and being, outside two recessed sides away from another truss setting a truss lower end are near another truss;
The upper open end of each V-arrangement connector is connected with last square tube, and the following blind end of each V-arrangement connector is connected with the vertical wing plate of sword shape angle steel;
Each arch sheet load is connected between two inboards recessed of per two adjacent truss lower ends;
Tectal upside surpasses square tube on the level of each truss.
Like this, make the simple and reasonable of this roofing.
Said covering layer is a cement sand bed.Like this, under the guaranteed precondition of heat insulating effect, make that the manufacturing cost of this roofing is lower.
Said covering layer is a double-layer structure up and down, and wherein: lower floor is foam concrete or polyphenyl particle heat-insulating mortar layer, and the upper strata is a layer of concrete.Like this, under the guaranteed precondition of heat insulating effect, make that the deadweight of this roofing is lighter.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and through embodiment.
Embodiment one
Referring to Fig. 1-Fig. 4:
This roofing comprise the plurality of vertical truss A that is parallel to each other, load be connected on arch sheet B between per two adjacent truss A lower ends, will per two adjacent truss A and the covering layer C of the containing of arch sheet B between the two.
For the purpose of ability concise description problem, only show two vertical truss A, an arch sheet B among Fig. 1, Fig. 2, Fig. 3.Two truss A can get corresponding length according to designing requirement, and then, overlap joint is on the body of wall or structural beams of both sides, house (not shown described body of wall or structural beams in the accompanying drawing).
Each truss A comprises the L shaped angle steel down of two levels that the vertical V-arrangement connector of square tube on the level 1, two 2, symmetry are in square tube 1 below and parallel with last square tube 1;
Two vertical wing plate 31 parallel interval of two following angle steel; Two horizontal wing plates 32 of two following angle steel stretch out and symmetric arrangement; Each down angle steel horizontal wing plate 32 and vertically have a angle 90 degree between the wing plate 31 and uncovered up recessed 33; So that there are inside and outside two recessed 33 of arranging each truss A lower end; And for per two adjacent truss A; In setting two recessed 33 of a truss A lower end sides and being, outside two recessed 33 sides away from another truss A setting a truss A lower end are near another truss A;
The upper open end of each V-arrangement connector 2 is connected with last square tube 1 through trip bolt; The following blind end of each V-arrangement connector 2 inserts between two vertical wing plates 31 of two following angle steel, and the following blind end of each V-arrangement connector 2 is through trip bolt be connected with two vertical wing plates 31 of two following angle steel (all not shown described trip bolt in the accompanying drawing);
