Description
Technical Field
The invention relates to the technical field of buildings, in particular to a fine stone concrete grid joint waterproof structure.
Background
Fine stone concrete has been widely used as a rigid waterproof layer for roofs. Because the design and the structure of the dividing joint are simpler and the site operation is more inconvenient, particularly, the joint filling material is too low in grade and has no sealing and waterproof function, the leakage occurrence rate is higher, and the whole rigid waterproof is not accepted by the specification any more. Since most flat roofs require a rigid protective layer, the rigid protective layer construction is, in fact, a once rigid waterproof layer.
For the roof with a heat-insulating and slope-finding structural layer, if the waterproof function of the protective layer is abandoned, the leakage rate can be increased; if the waterproof is failed, only the waterproof is pushed down and is worth researching. This is especially true for inverted roofs where the closed ballast layer (i.e. fine-stone concrete protective layer) is designed and the insulation is the dominant. The waterproof protective layer of the planted roof is mostly designed as fine stone concrete, and if the waterproof protective layer is endowed with root penetration resistance, the protection and root penetration resistance are combined into one, so that the investment can be greatly reduced. The solution to the above problems is first directed to improvements in the construction technique of the cell seam.

Detailed Description
The following describes the specific implementation of the present invention in detail with reference to the accompanying drawings.
The fine stone concrete grid joint waterproof structure comprises a pre-assembled mould strip 1, wherein a framework of the pre-assembled mould strip 1 is made of weather-resistant PVC, a horizontal part 104 of the pre-assembled mould strip is arranged below a fine stone concrete protection layer 9, a vertical part extends upwards, and after the fine stone concrete 9 is poured into the pre-assembled mould strip 1 and hardened, an upper section 102 of the pre-assembled mould strip 1 is removed.
Specifically, as shown in fig. 1, the pre-assembled mold strip 1 is in an inverted T shape and is integrally injection molded. Comprising a horizontal section 104 of the die strip, a vertical upper section 102 of the die strip, and a lower section 102 of the die strip, wherein the upper section 102 of the die strip and the lower section 101 of the die strip are connected by a weak connection 103, as shown in the left part of fig. 1. The vertical part of the pre-loading mould strip is provided with a pre-loading mould strip seam, and the weak connection between the upper section and the lower section of the pre-loading mould strip is specifically as follows: the inner side of the pre-filling mould strip seam is provided with a dotted dent which is 15mm away from the top surface, the through length is 0.5mm, the length is 4mm and the interval is 1mm; the side wall above the dent is 1mm thick.
