Abstract
The utility model relates to cement inherent stress composite net-frame board with the glass fibre enhancement. A face board is made up of low ph value cement (GRC) with the alkali-resistant glass fibre enhancement. The one-way inherent-stress reinforced concrete is used as a main rib, and the non inherent-stress reinforced concrete is used as a transverse side rib and a middle rib. The plane of the whole composite net-frame board is in the shape of a square or a triangle. The high intensity of the GRC, the impact resistant, and self waterproof performance can be fully played. The utility model has the advantages of simple moulding process, and low production cost. The self weight of the utility model is one half of the reinforced concrete net-frame board, and the anti-impact property is raised 16 times than the reinforced concrete net-frame board. The utility model is suitable for the matching board of various net-frame spatial structures.
Description
The utility model belongs to the structural element of building, particularly a kind of roof panel of rack space structures---network frame plate.
Rack is as a kind of novel space structures, by adopting on the public buildings such as the sports palace of large span, cinema, develops on combination multispan industrial premises and uses.Space truss structure not only can effectively utilize architectural space, satisfies the requirement of function of use better, adapts to the needs that technique change is upgraded, and alleviates than the reinforced concrete roof dead load of same scale, and construction is rapid, so application development is very fast.The rack space structures is to form space structures with the metal rod than small-sized, end face is done roofing coated with network frame plate, and constitute whole roof structure, the normal at present network frame plate that adopts is the steel concrete network frame plate, because from great, intensity is low, when adopting site prefabrication, production cycle is long, the die cost height; When adopting prefabrication, because the member crack resistance is low, the breakage rate height of handling process becomes the shortcoming that is difficult to develop again.Network frame plate also has metal crimp template or compressed straw slab to make, and the former heat-proof quality is poor, anticorrosion maintenance cost height, and the latter then moisture-sensitive is gone mouldy, and also affects Application Expansion.
The purpose of this utility model is the glass fibre cement material and the compound network frame plate of prestressed reinforced concrete material of a kind of high-strength light of design, to overcome the defective of existing a large amount of steel concrete network frame plates that adopt, alleviates deadweight, improves intensity.
Glass fiber reinforced cement prestressing force composite web frame plate of the present utility model, form by panel, main rib, limit rib, middle rib, it is characterized in that strengthening low alkalinity cement (being called for short GRC) by alkali resistant glass fiber makees panel, make vertical main rib by unidirectional prestressed reinforced concrete, make widthwise edge rib and middle rib by the nonprestressed reinforcement concrete, whole composite web frame plate plane is square or triangle, hexagon, octagon.Middle rib makes the cross rib of parallel edges rib or the groined type rib of cross, and panel makes flat board or coverboard form.
This by GRC panel and the compound network frame plate of prestressed reinforced concrete, adopt with a kind of cement material aluminium sulfate high-early (strength) cement, form whole stressed.GRC slab strength height, shock resistance, good from water resistance make and reduce the rib height by the attenuate thickness of slab, alleviate deadweight; The steel concrete rib then has ripe design and calculation method to determine intensity and toughness and crack resistance, and moulding process is simple, and cost of production is low.The steel concrete network frame plate of this kind composite web frame plate and existing same specification relatively, weight reduction half, shock resistance improves 15 times, and price only increases by 10 yuan for every square metre, therefore becomes the reasonably supporting plate of using of rack space structures.
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the front view of glass fiber reinforced cement prestressing force composite web frame plate
Fig. 2 is I-I sectional drawing of Fig. 1
Fig. 3 is II-II sectional drawing of Fig. 1
Fig. 4 is a triangle composite web frame plate front view
As seen from the figure, the main rib 2 that glass fiber reinforced cement prestressing force composite web frame plate is built moulding by the panel 1 and the Reinforced Concrete Materials of the moulding of GRC injection of material, limit rib 3 and middle rib 4 are formed, the thick 15mm of panel, length * wide=3000 * 3000mm, main rib section 50 * 150mm has 1 ∮, 12 presstressed reinforcing steels, limit rib section 50 * 120mm, 1 ∮, 12 reinforcing bars are arranged, and the middle rib section is trapezoidal, bottom width 100mm, high 115mm, 1 ∮, 14 reinforcing bars are arranged, and monoblock composite plate deadweight 585kg is after maintenance reaches design strength, can use the 16Tm tower mast to hang vertical main room, adopt lever vehicle to move horizontally bed board, a plate is installed is only needed 5 minutes, construction and installation are reliable rapidly.
When span during greater than 3 meters, available triangle composite web frame plate is established prestressed reinforcement at the main rib of hypotenuse direction, and middle rib adopts the right-angled intersection pattern to arrange.
