Abstract
The utility model discloses an anti-leakage prefabricated panel, in relation to a building components, in particular to a prefabricated panel for the housing in building, solving the existing prefabricated panels exist the technical difficulties of easy leakage from the joints. A vertical cavity is opened on the surface of the prefabricated panels. The outer edge height of the cavity is lower than the thickness of the prefabricated panel body, the outer edge width of which is less than the cavity width, and the sum of bottom thickness of the cavity and the height of the outer edge height of the cavity equals to the thickness of the prefabricated panel body. Compared with the prior art, the utility model has advantages of simple structure, simple method in accordance with existing construction, no leaking from the joints, and can be widely applied to the construction industry.
Description
Technical field
The utility model relates to a kind of building unit, the precast plate that particularly a kind of building is used.
Background technology
In the building construction now, adopt ready made steel concrete sheet material (abbreviating precast plate as) as the dividing plate between roof, house or each layer of building more.For the ease of shipment and construction, to compare with roof area, the precast plate area is less, again each precast plate is spliced to form the roof during construction.Because there is the slit in each precast plate splicing place, the constructor must not no longer take various technical measures to carry out the antiseep processing, as " two cloth, three oil " mode commonly used, is exactly brush three road waterproof paints on precast plate, and two-layer glass cloth is covered in the centre.But As time goes on, waterproof paint and glass cloth are aging gradually, damaged, and reason such as expand with heat and contract with cold, and cause the gap leakage water between the precast plate.This is the technical barrier that builing industry is difficult to overcome always.
Prior art personnel develop the polymorphic structure precast plate with antiseep function, but these precast plate complex structures, and cause the working procedure complexity.
The utility model content
The purpose of this utility model is: solve the technical barrier of the seam easy to leak that pre existing making sheet exists, provide a kind of simple in structure, make environment-friendly impervious leakage precast plate simple, that working procedure is simple, seam crossing water is difficult for leaking into soffit, saves time, economizes on resources.
The purpose of this utility model realizes by following technical proposals:
The antiseep precast plate comprises the precast plate body, offers groove longitudinally on the described precast plate body surface, and the outer height of groove is lower than the height of precast plate body, and the outer width is less than recess width.The precast plate body can be the middle precast plate that longitudinal hole is arranged, and also can be the sealing integral slab that does not have through hole.
Two longitudinal flutings about offering on the described precast plate body surface, the outer height of these two grooves is identical.Groove and outer thereof are symmetrical or asymmetric with the longitudinal midline of precast plate body.
The height sum of the bottom thickness of described groove and outer equals the height of precast plate body.
The beneficial effects of the utility model are, on precast plate, offer groove, the outer height of groove is lower than the precast plate body height, can allow precast plate when concatenation construction, its outer is tapped in the groove that is adjacent precast plate, both sides all are provided with reeded precast plate can splice continuously, has only a side that the precast plate that reeded precast plate can be used as outermost end or inner terminal is set, and keeping its external end edge is vertical plane.Bottom portion of groove thickness equates with the height of precast plate body with the height sum of its outer, can allow precast plate after splicing, keeps upper and lower surface to be in same plane respectively.The width of outer is less than the width of groove, after precast plate is spliced to form roof or floor, in groove, formed guiding gutter longitudinally between outer and the outer, the water of seam crossing seepage enters in this guiding gutter from the upper surface seepage of precast plate, the water yield of general seepage is limited, and precast plate itself can absorb a part, as long as the water in the guiding gutter is no more than the outer height, just not again the soffit along seam from precast plate leak out, and can discharge along guiding gutter.As seen, adopt the utility model of said structure, compared with prior art, have simple in structure, make simple, can construct according to existing job practices, the seam crossing water of splicing is difficult for leaking into the advantage of soffit, and construction can shorten, economize on resources man-hour, can be less with or need not be as the waterproofing materials of pitch class, have the environmental protection advantage, can be widely used in building trade.

Fig. 3 is a user mode schematic diagram of the present utility model;
Number in the figure, the 1st, precast plate body, the 2nd, groove, the 3rd, outer, the 4th, guiding gutter.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, this is the cross section that is positioned at the antiseep precast plate at edge, has only a side to be provided with groove 2 longitudinally, vertically is meant on the long side direction of precast plate, laterally is meant on the short side direction of precast plate.The outer 3 of groove 2 highly is lower than the thickness of precast plate body 1.The width of groove 2 is greater than the width of outer 3.
Be positioned at the middle antiseep precast plate cross section of splicing floor as shown in Figure 2, offer groove 2 respectively in the both sides on its long limit, the outer 3 of groove 2 highly also is lower than the height of precast plate body 1.Article two, groove 2 and outer 3 are with the longitudinal midline symmetry of precast plate body 1.The width of groove 2 is greater than the width of outer 3.The bottom thickness of groove 2 and outer height sum equal the precast plate body height.
During concatenation construction, antiseep precast plate as shown in Figure 3 left-hand thread on another piece antiseep precast plate, because the width of groove 2 is greater than the width of outer 3, then the outer 3 of antiseep precast plate fastens mutually, vertical guiding gutter 4 of sealing around having formed in groove 2; Because the bottom thickness and the outer height sum of groove 2 equal the precast plate body height, when left and right sides antiseep precast plate fastened, its outer 2 buckled into groove 3, made the joint of two precast plates can not produce dislocation up and down, kept at grade.
Adopt the floor of the antiseep precast plate amalgamation of said structure, only need to adopt common waterproofing work to get final product (because generally speaking, the water yield of seepage is limited, and precast plate itself can the absorption portion water yield), water from the precast plate upper surface seam crossing seepage of amalgamation, enter in the guiding gutter 4 along its seam, as long as the water level of disposable water inlet is no more than the height of outer 3, water will be enclosed in the guiding gutter 4 and suitable its flows to the precast plate two ends discharges.
