Abstract
The utility model relates to a prestressed concrete wild goose-shaped plate and is a thin roof plate of which the concrete is provided with built-in prestressed reinforcement. Two thin wall wing plates correspondingly, downwards and obliquely intersect at the angle of 31 DEG or 29 DEG, the wing plates and a rectangular beam which downwards extends at the intersection point form a structure having plates and a beam, and the upper edges of the two thin wall wing plates form horizontal side edges. The vicinity of the intersection point of the two thin wall wing plates and the rectangular beam is thickened in a haunch mode, the haunch width is 0.2 time the size of the width of each thin wall wing plate, the thickness of each thin wall wing plate is 50 mm to 60 mm, each plate surface can be provided with holes, and the width of the wild goose-shaped plate is 3m to 4m. The main function of the two thin wall wing plates is a supporting function, and other parts of the two thin wall wing plates can be used as compressive regions of a cross section; the two thin wall wing plates work with the rectangular beam, and have the function of a bearing structure. Because the rectangular beam exists, prestressed reinforcement can be intensively arranged in the rectangular beam, the crossing capability of the plate can be enhanced, and the utility model can be suitable for the production of a pretensioning method and a post-tensioning method. The plate can be provided with the holes by plate surfaces, one plate can be pulled from another plate, and a transverse skylight is formed. The utility model effectively solves the functional requirements of roof natural lighting and ventilation.
Description
Technical field
The utility model relates to a kind of concrete roof member.
Background technology
In available coagulation earth house surface member, be used to do the v-shaped folded plate that has of big width roofing element, this plate is in light weight, and design, making are simply.But beam, plate split, it needs the second pouring concrete as the following seam in gutter, is difficult to form integral body, and the seam crossing waterproofing work requires high, is easy to seepage.In addition, when making, prestressed reinforcement can only be along the single layout of plate width direction in plate, can not centralized arrangement, thereby can only use the pre-tensioning system construction, can not post-tensioned construction, and its span ability is restricted.
Technology contents
The utility model will solve the split of big width roof panel beam slab, construction joint complexity, easily leakage problems take place, and improves the span ability of beam slab.
The technical scheme of the utility model prestressed concrete goose-shaped board: be thin type roof panel at the built-in prestressed reinforcement of concrete, it is characterized in that: constitute plate-girder unification structure, the horizontal side of the top edge of two thin-walled wing plates downwards by downward relatively 30 ± 1 ° of inclination phase intersecting and merging of two thin-walled wing plates and the rectangular beam that extends at the intersection point place.
Haunch thickens near the intersection point of above-mentioned two blocks of thin-walled wing plates and rectangular beam, and haunching width=0.2 times plate is wide.
The thickness of above-mentioned two blocks of thin-walled wing plates is 50-60mm.
The thickness of the horizontal side of above-mentioned two thin-walled wing plates is 100-180mm.
On the above-mentioned thin-walled wing plate plate face perforate is arranged.
Above-mentioned rectangle depth of beam is 250-650mm.
The width of above-mentioned goose-shaped board is 3-4m.
Beneficial effect: the rectangular beam that the utility model is extended downwards by two blocks of thin-walled wing plates that tilt to intersect and intersection point place constitutes the cross section, space of plate-girder unification, or claims y-shaped cross-section.The major function of two blocks of thin-walled wing plates is to go along with sb. to guard him, shielded from sunlight, wind and rain, dust etc.; But its part is again as the pressure zone of cross section, with the rectangular beam co-operation, bear structure function.Because the existence of rectangular beam, can be in rectangular beam the centralized configuration presstressed reinforcing steel, improved the span ability of goose-shaped board greatly; The thickness of the horizontal side of two thin-walled wing plates is 100-180mm.Can adapt to pre-tensioning system and post stretching production; This goose-shaped board can also perforate on the plate face, and plate and plate are drawn back, and forms horizontal skylight, the highly effective functional requirement that has solved roof system daylighting and ventilation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
1-thin-walled wing plate, 2-rectangular beam, the horizontal side of 3-, 4-add tuck in, the 5-perforate.
The specific embodiment
Prestressed concrete goose-shaped board embodiment one as shown in Figure 1, it is thin type roof panel at the built-in prestressed reinforcement of concrete, the two block thin-walled wing plates 1 relatively downward-sloping phase intersecting and merging horizontal by the upper end dual-side constitute plate-girder unification structure with the rectangular beam 2 that extends at the intersection point place downwards, the fundamental section form is star or Y shape, about 30 ° of the optimum inclination angle of thin-walled wing plate.
Embodiment two as shown in Figure 2 can perforate 5 on the plate face.
The every size in cross section: the thickness of two blocks of thin-walled wing plates is 50-60mm, and the thickness of two thin-walled wing plate top edges, two horizontal sides 3 is 100-150mm.The height of rectangular beam 2 is 250-650mm.The width of goose-shaped board is 3-4m.During width 3m: thickness of slab 50mm, near haunch 4 intersection point of two blocks of thin-walled wing plates and rectangular beam.During width 4m: thickness of slab 60mm, haunching height=1 times thickness of slab, haunching width=0.2 times plate is wide.
Best span-depth radio: L
0/ 20～L
0/ 24, its mid-span deflection will be much smaller than the L that is strict with
0/ 400.
The falsework system: template is aided with a small amount of special-purpose steel template based on common general building iron template; Be welded into bracing frame and the dual-purpose support of model support with 50～60 angle steel, form the falsework system of light and flexible.Use the post stretching anchoring system: stretch-draw end sheet clamping type group anchor ground tackle, fixed end heading ground tackle.
