Abstract
The utility model relates to a high strength light hollow precast slab. The longitudinal lightening holes of the high strength light hollow precast slab are four long holes uniformly distributed and having octagonal cross sections, long shafts of the octagonal long holes are positioned on the horizontal center line of the cross section, and two long sides of the octagonal long holes are parallel to the horizontal center line. The hole rate of the precast slab is 50%. The lightening holes of the precast slab are the octagonal long holes formed on the basis of haunch on the four corners of the long square holes of the hollow precast slab with long square holes. Compared with the hollow precast slab with the long square holes, the utility model has high rigidity and strength, the weight of the utility model is lighter than that of a hollow precast slab with circular holes, and the utility model can mainly be used for wall partition boards of non-load bearing houses.
Description
The utility model relates to the thin plate that a kind of building parts are used.
At present, the hollow pre-fabricated panels that building uses is to be strengthened by alkaline-resisting grid cloth, mixes the moulding of a small amount of expanded perlite pressure casting in the low alkalinity cement mortar, standard gabarite is long 250-390 centimetre, and is wide 60 centimetres, high 6-9 centimetre, its lightening core is a kind of to be circular hole, and a kind of is oblong aperture.The hole ratio of circular hole hollow pre-fabricated panels is 30%, and the hole ratio of oblong aperture hollow pre-fabricated panels is 53%, and relatively, circular hole hollow pre-fabricated panels hole ratio is little, the intensity height, but weight is big, and oblong aperture hollow pre-fabricated panels hole ratio is big, and is in light weight, but intensity difference.
The purpose of this utility model is to provide a kind of intensity height, and is in light weight, and good rigidly has the light body hollow pre-fabricated panels of high strength of circular hole and oblong aperture hollow pre-fabricated panels advantage concurrently.
The purpose of this utility model realizes in the following manner:
The light body hollow pre-fabricated panels of a kind of high strength, its gabarite is long 250-390 centimetre, wide 60 centimetres, high 6-9 centimetre, wherein be provided with vertical lightening core, described vertical lightening core is that four uniform cross sections are octagonal slotted hole, and the major axis of described octagon slotted hole is positioned on the horizontal center line of described cross section, two long limit is parallel with described horizontal center line, and the hole ratio of the light body hollow pre-fabricated panels of described high strength is 50%.
The utility model has the advantages that: the lightening core of the light body hollow pre-fabricated panels of high strength of the present utility model is the octagon slotted hole that forms on the basis of four jiaos of places of oblong aperture of oblong aperture hollow pre-fabricated panels haunch, its hole ratio is lower than the hole ratio of oblong aperture hollow pre-fabricated panels, thereby precast plate plate face rigidity and impact strength have been improved, in light weight than circular hole hollow pre-fabricated panels again simultaneously, raw material have been saved, and octagon slotted hole manufacture craft performance is good, is not prone to and subsides or the crack.
Other details of the present utility model and characteristics can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings, wherein:
Fig. 1 is the structural upright schematic diagram of the light body hollow pre-fabricated panels of the utility model high strength.
With reference to Fig. 1, the material and the gabarite of the light body hollow pre-fabricated panels of the utility model high strength are carried out according to national existing standard.Its lightening core 1 is 4, is octagonal slotted hole along the vertical uniform cross section of plate.The major axis of slotted hole 1 is positioned on the horizontal center line of light body hollow pre-fabricated panels cross section, and two long limit 2 is parallel with horizontal center line.Octagon slotted hole 1 is to form on the basis of four jiaos of places of the oblong aperture of oblong aperture hollow pre-fabricated panels haunch 3, can be as required, be furnished with diameter at armpit 3 places and be 6 millimeters stiffener 4.The hole ratio of the light body hollow pre-fabricated panels of the utility model high strength is 50%, the cumulative volume of the cumulative volume/plate in hole ratio two holes.The preparation method of the light body hollow pre-fabricated panels of the utility model high strength is identical with the preparation method of known oblong aperture and circular hole hollow pre-fabricated panels.
The light body hollow pre-fabricated panels of high strength of the present utility model is mainly used in non-bearing house partition board, because of its have in light weight, the intensity height, the characteristics of good rigidly can substitute existing oblong aperture and circular hole hollow pre-fabricated panels.
Claims (2)
1, the light body hollow pre-fabricated panels of a kind of high strength, its gabarite is long 250-390 centimetre, wide 60 centimetres, high 6-9 centimetre, wherein be provided with vertical lightening core, it is characterized in that described vertical lightening core (1) is that four uniform cross sections are octagonal slotted hole, the major axis of described octagon slotted hole (1) is positioned on the horizontal center line of described cross section, two long limit (2) is parallel with described horizontal center line, and the hole ratio of the light body hollow pre-fabricated panels of described high strength is 50%.
2,, it is characterized in that described octagon slotted hole (1) armpit (3) locates to be furnished with stiffener (4) according to the light body hollow pre-fabricated panels of the described high strength of claim 1.
