Description

Wallboard with waterproof construction

Technical Field

The utility model relates to the field of buildings, in particular to a wallboard with a waterproof structure.

Background

Chinese patent CN206581440U discloses an "insertion fiber cement external wall module board", which has good connection strength and can be conveniently installed and detached, but the existing common wallboard waterproofing method in the market adopts materials such as sealant to prevent water at the joints of the wallboard, and does not consider the structural waterproofing, i.e. the joints of the wallboard are only sealed by weather-resistant sealant, and the waterproof sealing schematic diagram is shown in fig. 1 and 2. The single waterproof mode has the following defects that the waterproof performance has great hidden danger:

(1) is greatly influenced by the performance of the sealant. Once the sealant ages or fails, the wallboard substantially completely loses its waterproofing ability and the reliability of waterproofing performance is poor.

(2) Is greatly influenced by the displacement of the wall plate. This kind of wallboard relies on the peripheral recess of wallboard template board and fossil fragments to carry out fixed mounting each other spacing, under wind load or other exogenic actions, there is small displacement in the wallboard, and the displacement dislocation leads to sealed breaking or droing easily between the wallboard that frequently reciprocates, influences waterproof reliability then.

(3) The maintenance difficulty is large. Because the sealant has certain durability, the sealant of the wall board at each position of the building can be simultaneously broken or fall off, the maintenance of the wall board is difficult, the waterproof performance of the wall board during the maintenance period can not be guaranteed, and great hidden dangers exist.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Two water bars 2 that misplace each other are set up at the frame of wallboard, and the material of water bar 2 can also be processed with frame integrated into one piece with the frame of wallboard, and water bar 2 can stop inside further infiltration wallboard of outside water.

As shown in fig. 3, the water bar 2 of the lower wall plate 4 is arranged on one side of the water bar 2 of the upper wall plate 5 close to the keel 6, and a gap is arranged between the water bar 2 of the lower wall plate 4 and the water bar 2 of the upper wall plate 5. Firstly, guarantee the cavity space, secondly consider certain processing and construction error, when setting up according to this, outside breakwater 2 can play the effect of the breakwater that drips, when the upper portion breakwater leans on the interior setting, can have the water that flies to splash to cross the lower part breakwater and get into inside the wallboard in sealed position that drops completely, inside breakwater 2 can the general outside water of separation get into inside the wallboard. When the water bar 2 is made of metal, the surface is smooth, which is beneficial to the flow of external water, and can avoid the external water from permeating into the wallboard due to the capillary phenomenon under the long-term action.

The joint between the adjacent wallboards is filled with the sealant 1, and the modified polyether sealant (MS) and the silane modified polyurethane Sealant (SPU) have better comprehensive performance and can be preferably selected. It has excellent adhesion, displacement resistance, compatibility, weather resistance and pollution resistance.

When water breaks through a gap between the wallboard and the keel 6, the waterproof sealant of the material and the waterproof water bar 2 structure are waterproof, the water can be discharged to the outer side of the wall body through the drain hole 3 which is obliquely arranged downwards, and the drain hole 3 plays a role in draining water and keeping a cavity inside the wall body, and mainly plays a role in balancing the air pressure of the gap between the wallboard and the keel 6 and the air pressure outside the gap. The structural and material waterproofing of the inside of the wallboard is the same as the waterproofing of the outside of the wallboard. Theoretically, only when the wash port 3 that the place set up blocks up, and water can't follow vertical keel 6 when flowing automatically to the cavity of lower floor's wallboard, form under the condition of more ponding in the cavity, water just can be through the waterproof and material of the waterproof entering of structure of inboard setting indoor, and this condition is extreme, takes place the possibility less and should take place in the wallboard department of lower floor, so the waterproof measure of here is for redundant consideration.

As shown in figure 4, set up water-swelling's sealing rod 7 on the water bar 2 that is close to fossil fragments 6, sealing rod 7 can be embedded in water bar 2 or adopt other mounting means, should synthesize the reasonable height of considering water bar 2 and sealing rod 7, because of both high excessively cause horizontal piece seam gap too big or the insecure scheduling problem of wallboard installation when avoiding installing, the inboard sealing rod 7 of wallboard can set up or not set up according to actual conditions, and here is waterproof redundant design. The water bar 2 that the outside set up can block partly splash water on one hand, and on the other hand, avoids meeting water inflation sealing rod 7 extrusion outside sealed glue when expanding, causes sealed dropping of gluing. The waterproof construction scheme can effectively prevent splashed external water or general external water from entering the interior of the wallboard, and the waterproof safety and the redundancy are enhanced.

As shown in figure 5, the scheme only sets up a water bar 2 at the horizontal piece seam department in the wallboard inside and outside, and water bar 2 establishes in the upper end of lower part wallboard 4, and in the gap between 2 tops of water bar stretched into upper portion wallboard 5 and fossil fragments 6, should synthesize the big or small relation between the gap between 2 thickness of water bar and upper portion wallboard 5 and fossil fragments 6 of considering, avoid the space to lead to water bar 2 or fossil fragments 6 can't place inadequately. The water bar 2 in the shape can effectively prevent splashed external water or general external water from entering the interior of the wallboard, and the safety and the redundancy of water prevention are enhanced.

As shown in fig. 6, the water bar 2 of the left side wall plate 8 and the water bar 2 of the right side wall plate 9 are arranged in a staggered manner, and a gap is arranged between the water bar 2 of the left side wall plate 8 and the water bar 2 of the right side wall plate 9. The water stop strip 7 which expands when meeting water is arranged on the water stop strip 2 close to the keel 6, the water stop strip 7 can be embedded in the water stop strip 2 or other installation modes are adopted, the reasonable heights of the water stop strip 2 and the water stop strip 7 are comprehensively considered, and the problems that the vertical abutted seam gap is too large or the wallboard is not firmly installed and the like caused by too high heights of the water stop strip 2 and the water stop strip 7 are avoided; the inside construction measures of the wall panel are the same as the outside of the wall panel. The water-swelling water stop strip 7 can effectively stop splashing external water or general external water from entering the wallboard, and when the external water enters the wallboard, the water stop strip prevents the water from permeating into the wallboard through the vertical joint.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
