Abstract
The utility model discloses a bidirectional prestressed light compound net frame plate which is made up of a panel, frame ribs and reinforcing ribs, the bidirectional prestressed light compound net frame plate is characterized in that the panel made of fiber cements is square; the frame ribs with trapezoid cross-sections are equipped around the panel, and prestressed reinforcements are equipped in the ribs to make the four frames form bidirectional prestressed frame ribs. Reinforcing ribs are equipped on the ventral surface of the panel; thermal-insulating sheet materials are equipped between the ribs to form a thermal insulating layer. The bidirectional prestressed light compound net frame plate is provided with the self waterproof ability and can not deform and reduce the strength in moist conditions; the bidirectional prestressed light compound net frame plate ensures the tenacity and rigidity of the panel, and the deflection is overcome to produce, and the bidirectional prestressed light compound net frame plate is very suitable for single layer long-span roof structures.
Description
The utility model belongs to building unit, is applicable to make the single roofing, is particularly suitable for doing large-span steel space truss structure roofing.
The rack roofing plate that uses in the existing building construction mainly contains the unidirectional prestressed net frame plate of reinforced concrete roof board and GRC.But steel concrete network frame plate batch production production, but its exists from great, feed consumption is many, the problem that the transporting and hoisting workload is big, and this plate need add insulation in addition when using, make waterproof; Though the unidirectional prestressed net frame plate of GRC has reduced dead load, when using on the large bay structure, easily because of rigidity produces amount of deflection inadequately, plate and plate junction be easy to crack, leak, and also need do insulation in addition when using.
The purpose of this utility model is, provides a kind of two dimension prestressing light-duty composite web frame plate, makes it have the intensity height, globality is strong, do not need to be incubated in addition during use.
The light-duty composite web frame plate of two dimension prestressing of the present utility model is made up of panel, frame rib and ribs, it is characterized in that: the panel of being manufactured by fiber cement is square; Be provided with the frame rib of trapezoid cross section around panel, be furnished with prestressed reinforcement in the rib, make four frames form two dimension prestressing frame rib, the presstressed reinforcing steel in the rib adopts the reinforcing rib of 2 φ, 4 cold-drawn reinforcing ribs and φ 12～16; At evenly the distribute ribs of twice trapezoid cross section of the outside of belly of panel, be provided with reinforcing rib in the rib, reinforcing rib is the reinforcing bar of 2 φ, 4 cold-drawn muscle and φ 12; Between rib, be embedded with heat preservation plate material and form insulation layer.
The light-duty composite web frame plate of two dimension prestressing of the present utility model because surface layer has adopted fiber cement synthetic, has the ability from waterproof, and chance is wet indeformable, does not reduce intensity; The frame rib adopts concrete material to make, and is furnished with prestressed reinforcement in the rib, forms two dimension prestressing frame rib, guaranteed the toughness and the rigidity of plate, overcome the generation of amount of deflection, 70～100 kilograms of the every weight per square meters of this plate, 200 kilograms of every square metre of load are well suited for doing individual layer large bay roof structure.
The light-duty composite web frame plate of two dimension prestressing of the present utility model can be as required, and outside of belly ribs can be made the prestressing force ribs; The ribs of the outside of belly can be an arranged crosswise;
Can not do insulation layer for the roof structure that need not do insulation;
Heat preservation plate material can adopt perlite, glass wool or rock cotton board, mineral wool board, put out polyphenyl plate certainly.
The light-duty composite web frame plate of two dimension prestressing of the present utility model surface thickness is 15 millimeters, and the insulation layer thickness that need add insulation is between 30～95 millimeters, and the frame rib is high 150 millimeters, and ribs is high 115 millimeters.
The light-duty composite web frame plate of two dimension prestressing of the present utility model, on-gauge plate is of a size of 2970 * 2970 millimeters, also can make as required less than 6000 millimeters of the length of sides or abnormally-structured.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the elevation of the light-duty composite web frame plate of two dimension prestressing
Fig. 2 is the longitudinal plan of the light-duty composite web frame plate of two dimension prestressing

Fig. 6 is the C-C sectional drawing of Fig. 7
Fig. 7 is the rear elevation of the light-duty composite web frame plate of two dimension prestressing
As seen from the figure, the light-duty composite web frame plate of two dimension prestressing is a square plate body, plate is of a size of 2970 * 2970 millimeters, panel 1 is manufactured by fiber cement, be provided with the concrete frame rib 2 of trapezoid cross section all around, be furnished with prestressed reinforcement 4 in the rib, make four frames form two dimension prestressing frame rib, the presstressed reinforcing steel in the rib adopts the reinforcing rib of 2 φ, 4 cold-drawn reinforcing ribs and φ 12;
At evenly the distribute prestressing force ribs 3 of twice trapezoid cross section of the outside of belly of panel, be provided with reinforcing rib 5 in the rib, reinforcing rib is the reinforcing bar of 2 φ, 4 cold-drawn muscle and φ 12;
Be embedded with heat preservation plate material 6 and form insulation layer between rib, heat preservation plate material adopts rock cotton board.Four jiaos at plate are provided with hoisting ring 7.Thick 15 millimeters of the surface layer of plate has 10 millimeters fibre mortar topping under the insulation layer.
