The rooftop slab waterproof structure 100 using the composite sheet of the present invention has a structure in which the bending pieces 142 of the forming steel 140 are engaged with the installation grooves 141, which are inclined upward from the inner side of the parapet 12, A waterproof sheet 120 is formed so that an upper end of the waterproof sheet 120 is located below the installation groove 110 while an end of the waterproof sheet 120 is overlapped with the parapet 12 and the slab 11, And a bending piece 142 that is bent at an upper end of the plate member 141 is inserted into the sealing member 130. The sealing member 130 may be formed of a plate- A plurality of forming steels 140 are installed so as to be overlapped with the mounting grooves 110 so as to be embedded in the knocking blocks 150 and the knocking blocks 150 'to fix the forming steels 140 and the waterproofing sheets 120. [ And a fixing member 150 is mounted on the mounting hole 12 '. The fixing member 150 is fastened to the knife block 150' A protective member 160 for protecting the head portion of the fixing member 150 while being pressed on the forming steel 140 in accordance with the fastening force of the fixing member 150 is formed, And a gasket 170 mounted between the steel members 140 ', which will be described in more detail as follows.

And a pressing protrusion 143 protruding from the inside of the plate 141 to press the waterproof sheet 120.

And a reinforcing piece 144 bent at a lower end of the plate 141 to reinforce the plate 141.

And a sealing member 180 that is pressed against the forming steel 140 by a pressing force of the protecting member 160 according to the fastening force of the fixing member 150 to seal the sealing member 180.

Hereinafter, a construction process of the present invention will be described.

The installation groove 110 is formed in the inner surface of the parapet 12 of the structure 10 according to the design drawing so that the bent piece 142 of the forming steel 140 can be coupled And an installation hole 12 'in which the knife block 150' is coupled to the inner surface of the parapet 12 under the installation groove 110 is formed so as to be inclined upwardly from the inner side surface of the parapet 12, The inner surface of the parapet 12 of the structure 10 and the surface of the upper surface of the slab 11 are arranged.

The waterproof sheet 120 is seated on the parapet 12 and the slab 11 so that the end portions of the waterproof sheet 120 overlap the upper surface of the parapet 12 and the slab 11. The upper end of the waterproof sheet 120, And the waterproof sheet 120 is fixed to the parapet 12 and the slab 11 by a separate adhesive member (not shown), and the overlapped ends are welded and fixed by heat fusion.

When the waterproof sheet 120 is fixed to the parapet 12 and the slab 11, the sealing material 130 is filled in the mounting groove 110, and then the forming material 140 The plate member 141 of the forming steel 140 is brought into close contact with the waterproof sheet 120 while the bending piece 142 of the forming steel 140 is coupled to the mounting groove 110.

At this time, the through hole 141 'passing through the plate member 141 should be located on the same line as the installation hole 12' formed in the parapet 12, and the sealing member 141 ' (130) coagulates with a lapse of a predetermined time to close the inside of the installation groove (110).

When the foaming steel 140 is attached to the waterproof sheet 120 while being coupled to the installation groove 110, the protective body 161 of the protection member 160 is attached to the fixing member 150 to which the knife block 150 ' The fixing member 150 is coupled to the mounting hole 12 'through the through hole 141 of the forming steel 140. In this case,

The fixing member 150 coupled to the mounting hole 12 'is struck to connect the knife block 150' to the mounting hole 12 ', and then the fixing member 150 is rotated in one direction to form the knife block 150' The sealing member 180 is compressed between the foaming steel 140 and the protective member 160 by the tightening force of the fixing member 150 fastened to the forming member 140 to close the through hole 141 ' It is possible to block the inflow of water into the water pipe 141 '.

The pressing protrusion 143 protruding from the plate member 141 of the forming steel member 140 is firmly attached to the inner surface of the parapet 12 while pressing the waterproof sheet 120 by the fastening force of the fixing member 150 And a cap 162 connected to the protection body 161 of the protection member 160 may be mounted on the protection body 161 to cover and protect the head body of the fixing member 150. [

3 to 5, when the end of the forming steel 140 'adjacent to the end of the forming steel 140 is seated, the gasket 170 And the overlapping end portions of the adjacent forming steels 140 'are brought into close contact with the forming steels 140.

At this time, since the pressing projections 143 formed on the adjacent forming steels 140 'are easily joined to the recessed portions of the pressing projections 143 of the forming steel 140 while pressing the gasket 170, The fixing member 150 can be easily joined to the forming member 140 through the through holes 141 of the foaming steel 140 and the adjacent forming forming member 140 ' The process of fastening and fixing the fixing member 150 having the protective body 161 and the sealing member 180 to the knife block 150 'is repeated while the waterproof sheet 120 Can be supported by the forming member (140).

The water flowing down to the inner surface of the parapet 12 flows down to the bending piece 142 of the forming steel 140 and the water The water flowing into the slab 11 can be blocked by flowing down the drain pipe (not shown) of the structure 10 while flowing down the upper surface of the waterproof sheet 120 along the slabs 141.

Here, the sealing member 180 and the gasket 170 are preferably made of an adhesive rubber material.

Since the forming material 140 is reinforced by the reinforcing pieces 144 protruding from the lower end of the plate material 141, the forming material 140 can be used in a stable manner while preventing deformation due to external force.
