Multiple the complex waterproof sheet which has the structure overlap and manufacturing method of waterproof sheet and construction method for using the waterproof sheet }

The present invention improves durability and stiffness even in winter and summer when the temperature change is severe in waterproofing the roof of a building including an underground structure such as a parking lot, a building, an apartment, and a multi-family house, thereby minimizing its own deformation as well as improving it accordingly. The present invention relates to a composite waterproof sheet having a multiple overlapping structure for providing a waterproof function, a method for manufacturing the waterproof sheet, and a construction method using the waterproof sheet.

In general, the waterproofing method for the roof of buildings including underground structures such as parking lots, buildings, and houses includes a waterproof coating method for applying liquid waterproofing materials, and a sheet waterproofing method for laying sheeted waterproofing materials (waterproof sheets). In addition, there is a composite waterproofing method which is implemented by combining the coating film waterproofing method and the sheet waterproofing method.

By the way, the coating film waterproofing method is easy to construct a complex part or a vertical part, it is difficult to form a uniform waterproof layer when the waterproofing liquid is applied and if it is not dry enough (blowing-swelling phenomenon due to the air generated inside) may occur. There is a problem.

And the waterproof sheet method has the advantage that the thickness of the waterproof layer can be made constant, but the critical problem that the waterproofing function is lost due to deformation (lifting, breaking) occurs according to the external temperature and other factors (ground subsidence) There is this.

That is, due to the temperature difference between the winter and summer season, the joint of the waterproof sheet repeatedly relaxes and contracts, thereby failing to faithfully perform the waterproof function, which is a function of the original, and thus may cause construction defects.

In the present invention, to solve the problems described above, the manufacturing process is not only relatively simple, but also durable and rigid, as well as the waterproof sheet for maintaining the airtight adhesive state of the junction even in the change of season after construction and its It is an object to provide a manufacturing method.

Another object of the present invention in the construction of the joint of the waterproof sheet, by overlapping a plurality of layers by the construction method using a waterproof sheet to prevent the lifting and swelling phenomenon commonly occurred at the joint between the sheet and the sheet in advance. The purpose is to provide.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

First, the waterproof sheet 10 having the multiple overlapping structure provided by the present invention is rubberized asphalt 15 to the upper and lower sides of the sheet-shaped reinforcing net 16 composed of a plurality as shown in FIGS. 4 and 5. Is mixed, and the overlapping portion 11 of the double sheet structure is formed on the entire edge, and the sheet overlapping chip groove 12 having a predetermined depth is formed by the overlapping portion 11.

At this time, the release paper 20 is attached to the outer surface 14 and the sheet overlap groove 12 of the overlapping portion 11, the actual position of the release paper is attached to the sheet (A, A 'in the semi-finished state based on Figure 2 The inner side (shown in FIG. 2) is an edge, and the edge is an overlap 11 based on the composite waterproof sheet of the finished product which is pressed and fixed to the semi-finished state sheet.

In addition, the overlapping part is not sticking to each other even if the pressing on the secondary pressure roller by the release paper, the release paper is attached to the outer side of the overlapping portion as shown in Figure 4 'b' shape, the other side is to the front By allowing the release paper to be attached, the rolled paper may be provided with ease in storage.

Looking at the manufacturing method for the composite waterproof sheet 10 having a multi-ply structure of the present invention as described above, first, as shown in Figure 1 mixed with rubberized asphalt on the upper and lower sheet-like reinforcing net (16) At the same time, the sheet is passed through the primary pressure roller 70 to form a sheet, and the sheet thus formed is cut to a predetermined length at the cut portion 90.

The release paper is attached to the overlapping portion 11 of the outer side 14 and the inner side 13 with respect to the sheets A and A 'in the semi-finished state obtained in the cutting step by using a release paper attaching roller 30.

The sheet (A, A ') of the semi-finished state attached to the release paper is penetrated through the secondary pressure roller 80 in a state in which the inner side 13 is disposed to face each other as shown in FIG. By integrally thermally compressing as shown in Figures 4 and 5 it can be provided with a composite waterproof sheet in which the overlapping portion 11 and the sheet stack chip groove 12 is formed in the entire edge.

On the other hand, when looking at the construction method using a composite waterproof sheet having a multi-ply structure provided by the present invention first to arrange the basic ground of the construction surface, the basic ground clearance step, where the construction surface 40 protrudes After the surface grind, finish it with a mortar and make it round with a mortar on corners, corners, etc., cut off the cracked part on the construction surface, fill it with waterproof mortar, and reinforce it with a foreign material on the bottom of the construction surface. It is a process of removing (dust, sand, oil).

When the basic ground of the construction surface is arranged as described above, the primer is applied to the primer using any one of a roller, a brush, and a spray injection method, but the bottom of the construction surface is uniform.

When the primer coating step is completed, when the waterproof sheet 10 is laid from the edge of the wall with the structure as shown in Figs. 7 and 8 and when the second waterproof sheet is constructed, the overlapping portion 11 is shown in Fig. 6. (12) is sequentially inserted in the form of zig-zag, and at the same time to perform a waterproof sheet construction step by fixing the adhesive using heating or urethane bond.

In addition, when the heat is applied to the composite waterproof sheet of the present invention, the asphalt component is generated at the same time as the adhesive force can be formed in the airtight adhesion between each other, when the heat is applied to the heat generation dedicated machine including a torch.

The waterproof sheet is moved and stored in the form of a roll, and when the adhesive part is fixed by zigzag to obtain a triple triple adhesive fixing effect, it is possible to maintain a confidential waterproof state.

At this time, the waterproof sheet can be installed in a bent state according to the corner shape of the building when the construction, and after the construction is finished with silicon or the like.

When the construction of the waterproof sheet is completed, the overlapping part (adhesion part) is confirmed to be in close contact, and then the concrete is selectively poured by finishing the waterproof construction using the waterproof sheet, and the pressed concrete is exposed to the exterior of the composite waterproof sheet. In case of waterproof construction, press concrete pouring process may be omitted. In non-exposure construction which does not expose the waterproof sheet to the outside, cast pressed concrete.
