Abstract
The invention belongs to the floor construction field.It utilizes a kind of square disc steel bed die that has ridge design to make the one side of the hollow precast floor slab of casting have the grill-shaped decorative effect of embossment.Because the manufacture method of this precast plate and the job practices of utilizing this precast plate on-site consolidation superstructure and traditional conventional method are identical, thereby great applicability is arranged.And after superstructure is completed, can save the decorative engineering of ceiling, so comprehensive cost is lower than traditional job practices and has the good effect that beautifies dwelling house.
Description
The invention belongs to building floor construction field, further relevant with prefabricated hollow precast floor slab.
Current civilian both at home and abroad and method of construction of building roof industrial building mainly divides on-the-spot integrated poured and utilize concrete prefabricated board two kinds of methods of assembly unit at the scene.The former is applicable to that the structure to building has the building that higher mechanics requires or vibrationproof requires, and its cost is expensive, the construction requirement height; The latter is used for the less building of span mostly, in the domestic especially at present residential construction, uses the hollow precast floor slab job practices of assembly unit superstructure at the scene morely, and its cost is lower, and job practices is simpler.
But above-mentioned two kinds of methods all have a defective, promptly after superstructure completion, and for beautifying constructure all needs ceiling is done further processing, or floating with cement mortar, add swabbing; Or on ceiling decorative material such as the gypsum plank of installation forming or calcium-plastic board; So not only increase cost but also prolonged the duration.In order to address the above problem, the inventor once proposed two patent applications (86105743 and 86205263), the made from permanent ornamental moulded plate of cement compression moulding is used for on-the-spot integrated poured superstructure, make the superstructure bottom after the completion that is to say that ceiling has the grid-like decoration that has anaglyph, has exempted the decoration process of ceiling.Yet the method for construction of building roof of above-mentioned made from permanent ornamental moulded plate is only applicable to integrated poured superstructure, can't be applied at present in the method for construction of building roof of a large amount of on-site consolidation hollow precast floor slabs that exist of China.
After repeatedly designing and testing, the present invention is directed to the problems referred to above on the basis that does not change existing hollow precast floor slab job practices, a kind of decorative hollow precast floor slab and manufacture method thereof are proposed.The overall economic efficiency height of the precast plate of above-mentioned decorative hollow floor, and no matter when manufacturing and on-site consolidation superstructure, all there is not specific (special) requirements, but make the ceiling after the completion have the grill-shaped decorative effect of embossment, thereby have bigger positive role reducing cost and beautifying dwelling house.
The present invention is described with reference to the accompanying drawings as follows:
Fig. 1 is the decorative hollow precast floor slab schematic diagram;
Fig. 2 is a steel bed die plan view;
Fig. 3 is the 1-1 sectional drawing of Fig. 2;
Sectional drawing when Fig. 4 is the cast precast plate.
Before making decorative hollow precast floor slab, at first to make steel bed die (1) as shown in Figures 2 and 3, this steel bed die available thickness is that 2～3 millimeters square steel sheet is made, ridge design can be designed on request on its plane, 1～3 centimetre and make it to become plate-like must be slightly scrolled up all around.For the precast plate that makes manufacturing meets the existing construction custom of China, the planar dimension of bed die should be 50～80cm usually
2Positive square, the best is 50～60cm
2, so that be complementary with existing hollow pre-fabricated panels width.
When casting decorative hollow precast floor slab of the present invention, earlier complete steel bed die (1) earlier by the length and the width of precast plate, in order to save the steel bed die, can use not common bed die at the two ends of precast plate with ridge design, install limit mould (2) by traditional conventional method then, core (3), reinforcing bar (4), concrete perfusion (as shown in the figure) again; Through making vibration firm by ramming, take out the coring mould, by after the job specfication maintenance, dismantle Bian Mo and bed die, decorative hollow floor as shown in Figure 1 prefabricated.After the precast plate of making was assembled into superstructure according to a conventional method at the scene, its ceiling need not to process nature became the grid-like decoration with anaglyph.If ceiling is had the color requirement, in addition swabbing or in cement additive color.
The manufacture method of decorative hollow precast floor slab of the present invention and utilize the construction method of this prefabricated board assembly unit superstructure and traditional conventional method identical, the cost that increases is the expense of steel model mould, but compare with the operation such as further plaster of still needing behind the existing floor construction, then its overall economic efficiency is that the cost of every square metre of superstructure can reduce by 1.5～2.0 yuans. Owing to used prefabricated board of the present invention, can make only to come across senior public building at present The decoration form of ceiling enters average family, will play bigger positive role to beautifying dwelling house.
Claims (4)
