Abstract
Disclosed is a waterproof board for a horizontal joint of a precast exterior wall hanging board. A surface layer, a sealing groove and longitudinal ribs are made of PVC (polyvinyl chloride) plastics, the sealing groove is arranged in the middle of the waterproof board, the longitudinal ribs are arranged on two sides of the waterproof board, barbs are arranged on the outer sides of the ends of the longitudinal ribs, and the sealing groove is matched with an airtight rubber strip. The waterproof board is characterized in that an upper waterproof board and a lower waterproof board are arranged on the horizontal joint between two adjacent wall boards, a waterproof groove is arranged on the outer side of the upper waterproof board, a waterproof strip is embedded into the waterproof groove, the outer edge of the bottom of the waterproof strip is higher than the inner edge of the bottom of the waterproof strip, a water retaining groove is arranged on the outer side of the lower waterproof board, a water retaining strip is embedded into the water retaining groove, the outer edge of the upper portion of the water retaining strip is lower than the inner edge of the upper portion of the water retaining strip, a water retaining board is arranged on the outer side of the water retaining strip, and the outer edge of the upper surface of the water retaining board is lower than the inner edge of the upper surface of the water retaining board. Therefore, climbing of rainwater under the capillary action can be prevented, and infiltrated rainwater is effectively prevented from entering the joint of the board.
Description
Technical field
The utility model belongs to technical field of civil engineering, is specially precast facade link plate horizontal joint constructional waterproofing plate.
Background technology
Be accompanied by the development of Urbanization in China, building industry has become one of mainstay of the national economy industry, and the original construction method of China, construction worker's labour intensity is large, production efficiency is low, the poor bottleneck that has become the fast development of restriction building industry of site environment.The late 20th century, country has proposed the policy of modernization of the housing industry, and wherein, housing construction standardization, dwelling house component parts manufacture, construction and installation assemblingization are its cores.And precast facade link plate (hereinafter to be referred as prefabricated panel) is installed by plant produced, job site, can reduce labor strength, improve the efficiency of construction reduction of erection time.Therefore prefabricated panel is the best implementation of above-mentioned three target perfect adaptations.Prefabricated panel is produced in batches in factory, and the performances such as the insulation of wallboard self, waterproof and sound insulation are all very good.The weak link of prefabricated panel is that plate seam processes, and horizontal joint place especially deals with improperly and causes that very easily rainy day infiltration, winter are ventilative, and such problem has appearred in the prefabricated panel building that much comes into operation, and customer complaint is more.The plate end water stop for composite wall plate of patent No. ZL201110073036.9 is the waterstop that utilizes the vertical rib of two Intermediate Gray groove two sidebands, be separately positioned on two plate ends that adjacent wallboard is relative, by the seam waterproof that is up to the standard that is sealed and matched between rubber weather strip and groove and the rubber strip, stop rainwater under blast and capillarity, to infiltrate indoor.Though this method is waterproof, waterproof effect is desirable not enough.
The utility model content
The purpose of this utility model provides a kind of prefabricated panel horizontal joint waterproofing plate, makes prefabricated panel horizontal joint place waterproof effect more desirable.
For achieving the above object, the utility model provides a kind of precast facade link plate horizontal joint waterproofing plate, make surface layer, sealed groove and vertical rib by the PVC plastics, sealed groove is in the centre, and vertical rib is on both sides, the outside, vertical rib end is provided with hangnail, sealed groove matches with airtight of rubber, it is characterized in that: the horizontal joint between adjacent two blocks of wallboards is established splash guard and lower splash guard, and the outside of upper splash guard is provided with the waterproof groove, water-proof strip embeds in the waterproof groove, and outer, water-proof strip bottom is higher than interior edge; The outside of lower splash guard is provided with the dash groove, and water bar embeds in the dash groove, and outer, water bar top is lower than interior edge, and establishes a watertight shutter outside the water bar, and watertight shutter upper surface outer is lower than interior edge.
The utility model is because the outside of lower splash guard is provided with the waterproof groove, and water-proof strip embeds in the waterproof groove, and outer, water-proof strip bottom is higher than interior edge, can prevent that rainwater from climbing the water phenomenon under capillarity; The outside of upper splash guard is provided with the dash groove, and water bar embeds in the dash groove, and outer, water bar top is lower than interior edge, and establishes a watertight shutter outside the water bar, and watertight shutter upper surface outer is lower than interior edge, stops that effectively the rainwater of infiltration enters plate seam inside.
Description of drawings
Fig. 1 is the structural representation of splash guard on the utility model;
Fig. 2 is the structural representation of splash guard under the utility model;
Fig. 3 is the construction and installation schematic diagrames.
The specific embodiment
With reference to Fig. 1, upper splash guard: surface layer 1, sealed groove 2, vertical rib 3, hangnail 4, waterproof groove 5, water-proof strip 6, waterproof groove 5 is positioned at the splash guard outside, and water-proof strip 6 embeds in the waterproof groove, and outer, water-proof strip bottom is higher than interior edge.
With reference to Fig. 2, lower splash guard: surface layer 1, sealed groove 2, vertical rib 3, hangnail 4, dash groove 7, water bar 8, dash groove 7 is positioned at the lower water plate outside, water bar 8 embeds in the dash groove 7, outer, water bar top is lower than interior edge, and a watertight shutter 9 is established in the water bar outside, and watertight shutter upper surface outer is lower than interior edge.
With reference to Fig. 3, the processing and fabricating stage, superincumbent prefabricated panel 14 lower ends are imbedded splash guard in advance, following prefabricated panel upper end is imbedded lower splash guard in advance, its position is as follows: surface layer 1 is positioned at prefabricated panel plate end, surface layer 1 external surface is concordant with the wall panels end surfaces, and vertical rib 3, hangnail 4 are embedded in the prefabricated panel.Concreting, prefabricated panel horizontal joint waterproofing plate and prefabricated panel are combined into integral body, and other technique is finished, and is transported to the job site after the prefabricated panel maintenance moulding.
In the construction and installation stage, before the prefabricated panel installation in position, airtight 11 of the neoprene that will foam filled in the sealed groove 2, and water-proof strip 6 is embedded in the waterproof groove 5, and water bar 8 is embedded in the dash groove 7; At prefabricated panel inside top paste heat-preserving bar 10; Behind the prefabricated panel installation in position, water-proof strip 6 prevents from climbing the water phenomenon, and it is inner that water bar 8 stops rainwater to flow into the plate seam; Airtight 11 of the neoprene of both sides can jam-packed reaches the purpose of windproof, waterproof, insulation; At prefabricated panel plate seam outside filling polyethylene foamed rod 12, then clog building sealant 13 and prevent that further rainwater from infiltrating, and really realized triple waterproof, double heat insulation function at last.
