Abstract
The utility model discloses a transverse waterproof structure of a prefabricated external wall panel, which comprises an external wall panel, an arc-shaped groove and a decorative panel, wherein the arc-shaped groove is formed in the transverse edge of the outer side of the external wall panel, the external wall panel is sealed through the decorative panel after being spliced, and a through hole is formed in the decorative panel. The waterproof structure of the utility model adopts the arc groove structure arranged on the outer edge of the outer wall plate, and realizes the waterproof performance under the condition of not influencing the strength of the joint of the outer wall plate; the waterproof structure of the arc-shaped groove is a conventional arc-shaped structure which is not easy to hide water, is convenient to produce, and is not easy to damage when being positioned at the outer edge in the carrying process.
Description
Technical Field
The utility model relates to the technical field of prefabricated building components, in particular to a transverse waterproof structure of a prefabricated external wall panel.
Background
The external wall panel is an important component of modern fabricated building, and the waterproof property of the connecting seam is especially important in the installation of building components, and external water may permeate into a house along the connecting seam when the waterproof property of the connecting seam is poor in rainy days. The waterproof structure of the existing external wall panel generally adopts a staggered waterproof structure, namely a height difference blocking structure is arranged at a joint for blocking the permeation of water. Although the waterproof structure has good waterproof performance, the waterproof structure is a concave or convex part of the external wall panel, the structures are easily damaged by collision during transportation and carrying, and the strength of the external wall panel at the joint of the structures is influenced.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides the transverse waterproof structure which is simple in structure, not easy to damage and does not influence the strength of the joint of the external wall panel.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a horizontal waterproof construction of prefabricated wall panel, includes side fascia, arc recess and decorative board, the outside horizontal edge of side fascia be provided with the arc recess, seal through the decorative board after the side fascia concatenation.
Furthermore, the decorative board adopt the PVC board, the PVC board ageing resistance, corrosion resistance are strong, are fit for using on the outer wall, can not see on the outer wall behind the increase PVC board and have the dent, do not influence the whole pleasing to the eye of stair.
Further, the decorative board on densely covered be provided with the through-hole, the through-hole mainly plays the ventilation effect, rainwater can be followed the through-hole and discharged after the rainwater infiltration in rainy day, the moisture in the arc recess is blown by wind very easily and is volatilized after the rain stops, can let the quick dry state that resumes of joint line like this.
Further, the diameter of the through hole is 1-3 mm, the preferred aperture is 2mm, the aperture is too small and is easy to block in water, and the too large aperture can influence the strength of the decorative plate.
Furthermore, sealing strips are arranged between the external wall panels and can prevent water from permeating inwards.
Furthermore, the two arc-shaped grooves are combined into a semicircular groove, the arc-shaped structure is easy to produce and manufacture, and the slope is smooth and can not hide water.
The utility model has the advantages that: the waterproof structure of the utility model adopts the arc groove structure arranged on the outer edge of the outer wall plate, and realizes the waterproof performance under the condition of not influencing the strength of the joint of the outer wall plate; the waterproof structure of the arc-shaped groove is a conventional arc-shaped structure which is not easy to hide water, is convenient to produce, and is not easy to damage when being positioned at the outer edge in the carrying process.
Drawings
Fig. 1 is a schematic structural view of a transverse waterproof structure of a prefabricated external wall panel according to the present invention.
Detailed Description
The utility model is described in detail below with reference to the accompanying drawings:
in the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "inside", "outside", "upper" and the like are based on the directions or positional relationships shown in the drawings or the directions or positional relationships which are usually placed when the products of the present invention are used, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to be referred must have a specific direction to construct and operate in a specific direction, and thus, cannot be construed as limiting the present invention.
As shown in figure 1, a horizontal waterproof construction of prefabricated exterior wall panel, including side fascia 1, arc recess 2 and decorative board 3, the outside horizontal edge of side fascia 1 be provided with arc recess 2, arc recess 2 is the quadrant circular, this kind of arc is conventional arc, simple manufacture to can not hide water. The outer wall panel 1 is sealed by the decorative panel 3 after being spliced. Be used for installing decorative board 3 in the edge of arc recess 2 and be provided with the platform of caving in, guarantee decorative board 3 installation back and side fascia 1 parallel and level. Decorative board 3 adopts the PVC board preparation of the good ageing resistance of corrosion resisting property, and the thick cloth of board is provided with through-hole 4 that the diameter is 2mm, and through-hole 4 is arc recess 2 ventilation, makes things convenient for 2 surfaces of arc recess to air-dry. The through holes 4 are distributed only in the middle area of the decorative plate 3.
When the external wall panel 1 is installed, a sealing strip 5 is arranged between the panels, and waterproof coatings are sprayed on the arc-shaped grooves 2 and the sealing strips 5 to prevent water from infiltrating.
Although particular embodiments of the present invention have been described and illustrated in detail, it should be noted that various changes and modifications could be made to the above-described embodiments without departing from the spirit of the utility model and the scope of the appended claims.
