Referring to fig. 1, in order to seal the edge of the parapet wall 2 where the first waterproof layer 11 is erected, the possibility that the penetrating rainwater penetrates through the gap between the first waterproof layer 11 and the parapet wall 2 during subsequent use is reduced. The first waterproof layer 11 is arranged at the edge of the first protective layer 51, and a first sealing layer 12 formed by caulking and filling sealant is arranged on the first waterproof layer, and the first sealing layer 12 is fixedly connected to the edge of the first waterproof layer 11 and the edge of the parapet wall 2.

The border that first waterproof layer 11 set up in parapet 2 still is provided with connecting piece 6 to be used for taking a photograph of the border in parapet 2 to first waterproof layer 11 and do further protection, reduce the possibility that causes the damage to first waterproof layer 11 in the work progress.

Referring to fig. 1, connecting piece 6 is platelike structure, and the vertical cross-sectional profile of connecting piece 6 is the stairstepping to the last border laminating of connecting piece 6 is provided with a plurality of fixed subassemblies 4 in the border of parapet 2, in order to be used for with connecting piece 6 fixed connection in parapet 2 in the border setting of parapet 2. The lower edge of the connecting piece 6 is folded towards the edge far away from the parapet wall 2 to transit the first sealing layer 12; then the lower limb of connecting piece 6 is along vertical turning over a setting down to be used for pressfitting fixed strip 3, outside cement mortar, instrument etc. optimize the stability of first waterproof layer 11 set up in parapet 2 wall to first waterproof layer 11 and fixed establishment's influence when reducing the construction.

In addition, the upper edge of the connecting piece 6 is embedded in the gap between the upper edge of the connecting piece 6 and the parapet wall 2 by adopting sealant, and a second sealing layer 61 is formed, and the second sealing layer 61 is fixedly connected to the parapet wall 2 and the upper edge of the connecting piece 6 so as to be used for preventing the gap between the connecting piece 6 and the parapet wall 2 and further preventing the gap between the first waterproof layer 11 and the parapet wall 2 from being waterproofed.

Referring to fig. 1, in order to make the first waterproof layer 11 relatively tightly combined to the parapet wall 2, the surfaces of the parapet wall 2 and the base layer 1 are further paved with cement mortar to form a transition layer 7. The surface that the internal corner transition part that transition layer 7 is located parapet 2 and basic unit 1 keeps away from parapet 2 is arc surface form structure, and first waterproof layer 11 is laid on transition layer 7 surface to make first waterproof layer 11 can be comparatively more gentle relatively and inseparable lay the bight position between parapet 2 and basic unit 1, reduce the possibility that leads to the hollowing to produce because of the angle of bight. Wherein, first waterproof layer 11, first sealing layer 12, second sealing layer 61, connecting piece 6 all laminate transition layer 7 and set up.

In order to further reduce the influence of construction, turnover and the like on the waterproof performance of the first waterproof layer 11 at the transition part between the parapet wall 2 and the base layer 1, the transition layer 7 at the transition corner part between the parapet wall 2 and the base layer 1 is further paved with waterproof coiled materials to form an additional waterproof layer 13, and the two side edges of the additional waterproof layer 13 are respectively arranged on the part of the transition layer 7 at the parapet wall 2 and the part of the base layer 1, so that the additional waterproof layer 13 is arranged on the parapet wall 2 and the base layer 1 through the transition layer 7. And the additional waterproof layer 13 is lapped on the transition layer 7 and is positioned on the parapet wall 2 part and the base layer 1 part, and the width of the transition layer is more than or equal to 250mm, so that the corner part of the transition layer 7 is further enhanced in waterproof performance.

Referring to fig. 1, the second protective layer 52 is an insulation board, preferably a polystyrene board, such as an EPS polystyrene board, an XPS polystyrene board or a graphite polystyrene board, and a leveling layer 53 and a decorative surface layer 8 are sequentially laid on one side of the second protective layer 52 away from the base layer 1, and a decorative surface layer 8 is also laid on one side surface of the first protective layer 51 away from the parapet wall 2. When in use, the first protective layer 51 can be decorated by the decorative surface layer 8 and isolated from the outside; in addition, screed-coat 53 can be used for bearing the load of pedestrian or article simultaneously, can also do the buffering through first protective layer 51 and second protective layer 52, reduce and lead to producing the displacement difference between first waterproof layer 11 and basic unit 1 or parapet 2 because of the expend with heat and contract with cold of architectural surface 8 or screed-coat 53 to lead to first waterproof layer 11 to produce the possibility that the hollowing or the damaged condition of production appears, screed-coat 53 is for adopting cement mortar to lay in the surface forming that first waterproof layer 11 is located basic unit 1 part.

In other embodiments, the leveling layer 53 may not be provided, and the second protective layer 52 may be formed by applying cement mortar to the first waterproof layer 11.

Referring to fig. 1, a gap is formed between one side edge of the second passivation layer 52 facing the parapet wall 2 and the first passivation layer 51, and a buffer plate 54 is embedded in the gap between the second passivation layer 52 and the first passivation layer 51. When using, can do the buffering through buffer board 54 to the expend with heat and contract with cold of second protective layer 52 and screed-coat 53, reduce because of the engineering time is inconsistent, lead to because of new and old faying face appearance clearance between second protective layer 52 and the first protective layer 51, influence waterproof performance to when reaching to reduce waterproofing membrane and appearing breaking away from or the turn-up condition appears, waterproof performance after can also effectual optimization construction completion.

In order to further reduce the influence of the old and new bonding surfaces on the waterproof performance, the gap between the buffer plate 54 and the decorative surface layer 8 is caulked with a third sealing layer 541 using a sealing paste for sealing the gap between the buffer plate 54, the first protective layer 51, and the second protective layer 52.

The implementation principle of the embodiment 1 is as follows: when in use, the edge of the first waterproof layer 11 is pressed on the surface of the transition layer 7 through the fixing strip 3, and the possibility of hollowing generated when the first waterproof layer 11 is laid is reduced through the transition layer 7 arranged on the surfaces of the base layer 1 and the parapet wall 2; the fixing strip 3 is fixedly connected to the parapet 2 through the fixing component 4, and a gap between the first waterproof layer 11 and the parapet 2 is sealed through the first sealing layer 12, so that the situation that the first waterproof layer 11 is turned over or separated in the construction process is further reduced; in addition, can also do the buffering through buffer board 54 to the expend with heat and contract with cold of screed-coat 53 and second protective layer 52, can be comparatively inseparable packing in the clearance between second protective layer 52 and first protective layer 51, reduce because of new and old faying face, to the influence of clearance waterproof performance between parapet 2 and second protective layer 52.

Example 2

Referring to fig. 2 and 3, the difference between the embodiment and embodiment 1 is that the fixing assembly 4 disposed on the first waterproof layer 11 includes a fixing screw tube 41 and a fixing screw 42, the fixing screw 42 is inserted into the fixing screw tube 41, the fixing screw tube 41 and the fixing screw 42 are disposed on the same central axis, one end of the fixing screw tube 41 far away from the fixing screw 42 is a closed structure, a connecting portion 411 having a tubular structure is formed by inward sinking of an opening edge of one end of the fixing screw tube 41 facing the fixing screw 42, and the connecting portion 411 is sleeved outside and screwed on the fixing screw 42.
