Description
Technical field
The utility model relates to concrete hollow floor cast-in-site building unit, particularly relates to a kind of ribbing cavity building roof component and cavity building roof.
Background technology
In order to alleviate the dead load of concrete building cover plate better, control the deflection deformation of floor, and save reinforcing bar, reduce comprehensive cost, to meet low-carbon (LC), energy-saving and environmental protection requirement, floor plan many employings cast-in-place concrete hollow floor slab technology, the one-tenth pole that it adopts, or claim internal mold, be divided into two classes, one class is hollow cylinder core casing, such as all kinds of thin-wall hollow pipe; One class is cylindrical shell, the block of light solid, such as, a kind of cast-in-situ concrete hollow building roof filling bar disclosed in Chinese patent ZL200720030993.2, and shape is solid bar-shaped, cross section is circular or rectangle; Its material is hard high molecular foam material; Preferred with polystyrol foam material.
Existing all kinds of hollow thin-wall pipe fitting is when floor slab construction, not only need the top concreting at thin-wall pipe; the bottom of thin-wall pipe also needs concreting; otherwise the floor formed cannot the object such as ceiling-mounted light; therefore; when using existing hollow thin-wall pipe fitting to build hollow building cover; H-shape cross section can only be applied to; namely; hollow thin-wall pipe fitting surrounding, above, below all wiretie, concretings; and this thin-wall pipe is when concreting, and easily floating and generation lateral displacement, adds difficulty of construction.
Summary of the invention
For solving prior art Problems existing, the utility model provides a kind of ribbing cavity building roof component, rib is utilized to be raised by casing, between casing and bed die, there is space, during cast-in-situ concrete, concrete can enter between casing and bed die, forms the layer of concrete that one deck is relatively thin, both convenient construction, too increases the durability that position filled by casing.
The ribbing cavity building roof component that the utility model provides, comprises casing, it is characterized in that: described casing is netted casing, and this netted casing is surrounded by reticular lamina, and described reticular lamina comprises brace, forms grid between adjacent tabs; Described reticular lamina is provided with reinforcing rib, and wherein, the reinforcing rib on described netted wall box is perpendicular to horizontal plane; The bottom of described casing is provided with many roots.
By arranging rib, casing is elevated, during construction, the direct frame of casing, on bed die, leaves space between casing and bed die, during cast-in-situ concrete, concrete enters bottom half, forms one deck layer of concrete, and, the reinforcing cage of rib and casing periphery can be banded together, make the concrete of bottom half be combined better with periphery concrete; Rib preferably adopts reinforcing bar.Traditional casing generally adopts cement products, box house fills inorganic fire-retarded shaped material, on the one hand, cement products limits by environment, as temperature, humidity etc. when producing, construction progress is not easily held, on the other hand, cement products easily damages, and breakage rate is higher, for avoiding damaging the thickness that need control casing, the excessive casing that can cause again of thickness is overweight.The utility model adopts netted casing, produces not by environmental constraints, as long as and the reticular lamina of making casing is durable, as adopted steel mesh, can guarantee that casing yield rate is absolutely.Reticular lamina arranges the intensity that reinforcing rib can guarantee reticular lamina and the netted casing after being shaped.
Preferably, the angled setting of described brace, namely; in described reticular lamina horizontal positioned situation; there is between described brace and horizontal plane the angle being not more than 90 °, the brace of angled setting, be equipped with suitable sizing grid again, can guarantee that concrete is difficult to enter in netted casing.
Preferably, described casing is netted casing, and this netted casing is surrounded by reticular lamina, and described reticular lamina comprises brace, forms grid between adjacent tabs.Make for convenience of reticular lamina, described reticular lamina also comprises junction plate, and described grid is surrounded by brace and junction plate, and a junction plate can coordinate with polylith brace and forms multiple grid, and junction plate can also increase the bulk strength of reticular lamina.
For larger-size netted casing, for ensureing quality and the crushing resistance of casing, be provided with support member in described netted casing, described support member is trapezoidal or inverted V-shaped.
For guaranteeing the intensity of reticular lamina and the netted casing after being shaped, described reticular lamina is provided with reinforcing rib, and wherein, the reinforcing rib on described netted wall box is perpendicular to horizontal plane.
Preferably, described reinforcing rib is V-shaped, and V-arrangement opening is towards box house, and the top of V-arrangement reinforcing rib exceeds brace, and during concreting, V-arrangement reinforcing rib is combined closely with concrete, and casing is combined with layer of concrete better.
The area of described grid is not more than the infiltrating area caused by concrete surface tension force, and grid can prevent concrete from entering box house, simultaneously, concrete can enter grid, now, concrete is combined with the reticular lamina of netted casing and forms reinforced concrete floor, adds concrete intensity
Preferably, described grid adopts quadrilateral mesh.
During for avoiding cast-in-situ concrete, casing drifts about, and the top of described casing arranges fastening devices, as reinforcing bar etc., utilizes fastening devices to be fixed on periphery reinforcing cage by casing, avoids casing to move.
The utility model also provides a kind of tee-section cavity building roof, comprises reinforced concrete girder, waffle beam, top flange plate, bottom wing listrium and obturator; Described obturator adopts the ribbing cavity building roof component described in the arbitrary claim of claim 1-6.Use ribbing cavity building roof component as obturator, effectively can control the weight of obturator on the one hand, avoid obturator damaged when constructing, on the other hand, ribbing cavity building roof component can directly be placed on concrete bottom die, during concreting, the reinforcing rib of lower box and concrete form steel concrete thus form bottom wing listrium.
The utility model has the following advantages: (1) arranges reinforcing rib at bottom half, raises casing, forms reinforced concrete floor when building at bottom half, cavity building roof yield rate is obtained and ensures, and more both artistic and practical.(2) arrange fastening devices at casing top, fastening devices is fixed on casing periphery reinforcing cage, when avoiding building, casing drifts about.(3) casing adopts netted casing, improves yield rate, simplifies casing preparation method.(4) netted casing is provided with V-arrangement reinforcing rib, while reinforcing casing, builds rear V-arrangement reinforcing rib and is combined closely with concrete, casing is combined with layer of concrete better.(5) be provided with trapezoidal or inverted V-shaped support member in casing, make casing more stable.
