Abstract

The utility model relates to a saddle-shaped pre-fabricated plate mould for buildings, which is composed of six main beams, a right and a left stretching beds, and a saddle-shaped mould plate in a minus gauss hyperbolical paraboloid, wherein two upper beams and two lower beams are formed into an oblong body; both ends of the four beams are respectively fixed to the left and the right stretching beds; two middle beams are fixed to an appropriate position on the middle parts of the left and the right stretching beds; the left and the right stretching beds are provided with steel bar through holes. A pre-fabricated plate for buildings produced by the utility model has the advantages of no water accumulation, simple construction, short construction period, no extension of ridges and low cost.

Description

The prefabricated template die of the shape of a saddle for building

The utility model relates to the prefabricated template die of a kind of shape of a saddle for building.

At present, the used large span prefabricated board of building mainly contains two kinds, a kind of is the steel roof truss structure, another kind is the thin webbed girder structure, uses the prefabricated board of these two kinds of structures, and buildings must be produced ridge, to prevent buildings roof ponding, make buildings increase extra height, simultaneously, these two kinds of prefabricated boards all exist cost height, complicated, the long in time limit shortcoming of construction.

The purpose of this utility model is at the prior art above shortcomings, provide a kind of shape of a saddle for building prefabricated template die, when utilizing the shape of a saddle prefabricated board of this mould production to be used for the buildings of large span, not only need not increase the extra height of buildings, and cost is low, and construction is simple, the duration is short; The roof is ponding not.

The purpose of this utility model is achieved in that the prefabricated template die of a kind of shape of a saddle for building, comprise girder, stretching bed and bracing frame, the total six roots of sensation of girder that it is characterized in that this mould, i.e. two bottom girders, on two central sills and two, beam, wherein two bottom girders and two are put the beams in place and are constituted a rectangular parallelepiped, two bottom girders and two two ends of putting the beams in place are separately fixed on the stretching bed of the left and right sides, the two ends of two central sills also are separately fixed on the appropriate location at stretching bed middle part, the left and right sides, become the bracing frame of M shape to be uniformly distributed in two pairs upward between the bottom girder, and be fixed on, on the bottom girder, become the shape of a saddle template of negative gauss hyperbolic limit object plane shape to place on two upper beams and two intermediate beams, a left side, design has reinforced steel bar perforation on the right stretching bed, the spacing in hole be so that the reinforcing bar of wearing cloth by reinforced steel bar perforation diagonal angle on the stretching bed of the left and right sides can reticulate is as the criterion, but the position of reinforced steel bar perforation should be higher than the edge of shape of a saddle template on the stretching bed.

The utility model compared with prior art has the following advantages: 1, owing to the utlity model has into the shape of a saddle template of negative gauss hyperbolic paraboloid, so radian of oriented arch bottom the prefabricated board of the utility model production, so can ponding, buildings does not need to increase the extra ridge height that goes out again, and has fallen at the end cost; 2, owing to use its reinforcing bar of prefabricated board of the utility model production to wear cloth to reticulate, meet best mechanics principle, improved the intensity and the bearing capacity (span of product can reach 9.3～24 meters) of product greatly, enlarged the usable range of product; When 3, the product of use the utility model production is used for buildings, can makes the grillage unification and replace house beam, must not re-use the stilt of any increase roof intensity in the buildings; 4, the utility model is easy to use, is convenient to transportation.

With the embodiment that seals most of the present utility model in detail the utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 is a main TV structure synoptic diagram of the present utility model;

Fig. 2 is a plan structure synoptic diagram of the present utility model;

Fig. 3 is a right TV structure synoptic diagram of the present utility model.

As Fig. 1, Fig. 2, shown in Figure 3, two foundation beams 5 and two rectangular parallelepipeds of 2 formations of putting the beams in place, two bottom girders 5 wherein, the two ends of two upper beams 2 are separately fixed at left and right sides stretching bed 3, on 4, the two ends of two central sills 6 are separately fixed at left and right sides stretching bed 3, on the appropriate location at 4 middle parts, become the shape of a saddle template 1 of negative gauss hyperbolic paraboloid to place on two 2 and two intermediate beams 6 of putting the beams in place, become the bracing frame 9 of M shape to be distributed on two pairs, bottom girder 2, between 5, and be fixed on, bottom girder 2, on 5, left and right sides stretching bed 3, all design on 4 reinforced steel bar perforation 8 is arranged, the spacing in hole 8 is so that by left and right sides stretching bed 3, the reinforcing bar that cloth is worn at reinforced steel bar perforation 8 diagonal angles on 4 reticulates and is as the criterion, left and right sides stretching bed 3,4 top also becomes the arcuation identical with the edge of template 1, and the position of reinforced steel bar perforation 8 should be higher than the edge of template 1.10 is collar tie beam tie points among the figure.In order to increase intensity of the present utility model and to make its appearance looks elegant, should wrap one deck steel plate in the front-back and the bottom surface of the rectangular parallelepiped last, that bottom girder constitutes.

Because the product that uses the utility model to produce becomes the saddle to arch, therefore make the roof ponding not of buildings, and since the reinforcing bar of product inside wear cloth and reticulate, the intensity and the bearing capacity of product have been improved greatly, can not only satisfy of the requirement of long span building thing to intensity and bearing capacity, and need not use any roof carrier, need not use house beam yet.Product of the present utility model can satisfy the requirement of 9.3～24 meters span buildingss, be widely used in the big-and-middle-sized buildingss such as factory building, stadiums, than the present general like product 40-50% that reduces cost, reduce by 3～5 meters of depth of buildings, the reduction of erection time is over half.

Claims
