Description

Technical Field

[0001] The utility model belongs to the technical field of roof structures, and in particular relates to a roof structure with reserved separation seams. Background Art

[0002] In the roofing project of a building, whether it is an inverted roof structure or an upright roof structure, a separation joint must be reserved. The traditional roof separation joint construction is to bond the extruded board separation strip to the waterproof layer for temporary fixation, then use mortar footing to fix it, and then pour the protective layer concrete and use sealant to fill the joint. During the roofing project construction, the sealant filling joint often cannot be followed by the construction of the protective layer. During this period, the separation joint is open. Once it rains, rainwater will enter the insulation layer under the protective layer through the gap of the separation strip. Since the extruded board separation strip and the bottom of the mortar footing are tightly combined with the waterproof layer, a water retaining dam is formed. The rainwater cannot be discharged along the slope, which will cause water accumulation in the roof separation joint partition, which will cause roof leakage over time. In order to improve the quality of roof waterproofing and reduce the risk of roof leakage, a hydrophobic roof structure is needed. Utility Model Content

[0003] The purpose of the embodiment of the utility model is to provide a roof structure with a reserved separation seam, aiming to solve the problem in the prior art that the roof separation seam is prone to cause roof leakage after water enters the roof separation seam.

[0006] Furthermore, the upper surface of the extruded board dividing strip is lower than the upper surface of the protective layer.

[0007] Furthermore, the upper surface of the mortar foot guard is flush with the upper surface of the protective layer, and a gap is formed between the mortar foot guard and the upper end of the extruded board partition strip.

[0008] Furthermore, both sides of the upper end of the mortar foot guard form inclined surfaces.

[0021] like Figure 1 and Figure 2 As shown, a roof structure with a reserved partition 5 provided by an embodiment of the utility model, the roof structure includes a structural layer 1, a waterproof layer 2, a thermal insulation layer 3 and a protective layer 4 stacked in sequence from bottom to top, a partition 5 open to the outside is reserved from the waterproof layer 2 upward, a hydrophobic plate 8 is arranged between the partition 5 and the waterproof layer 2, the width of the hydrophobic plate 8 is greater than the width of the partition 5, and the hydrophobic plate 8 is arranged along the extension direction of the partition 5, the partition 5 is located in the upper middle part of the hydrophobic plate 8, and a drainage channel is formed between the hydrophobic plate 8 and the waterproof layer 2. The hydrophobic plate 8 is also called a water filter plate and has an excellent drainage ditch function. An extruded board partition strip 6 located above the hydrophobic plate 8 is arranged in the partition 5, and the extruded board partition strip 6 is connected to the hydrophobic plate 8. Mortar foot guards 7 are arranged on both sides of the partition 5, and the mortar foot guards 7 are fixed on both sides of the extruded board partition strip 6 and are located at the upper end of the hydrophobic plate 8. The width of the mortar foot guard 7 is smaller than the width of the hydrophobic plate 8, and the mortar foot guard 7 is located in the middle of the hydrophobic plate 8 to ensure that rainwater infiltrating from the separation joint 5 can effectively pass through the hydrophobic plate 8 and then enter the drainage channel.

[0022] In this embodiment, the width of the hydrophobic plate 8 is 30 cm, which is directly placed above the roof waterproof layer 2 and arranged along the dividing seam 5 in the vertical and horizontal directions. The width of the extruded board dividing strip 6 is 2 cm, and its height is 1 cm lower than the upper surface of the protective layer 4, which is arranged along the dividing seam 5 in the vertical and horizontal directions. The width of the seam mortar foot guard 7 on both sides of the extruded board dividing strip 6 is 5 cm, and both sides of the upper end of the mortar foot guard 7 form inclined surfaces. After the roof construction is completed, even if rainwater penetrates into the waterproof layer 2 through the dividing seam 5 and the protective layer 4, water will not accumulate inside the roof due to the drainage channel above the hydrophobic plate 8.

[0023] As an implementation method, the bottom of the extruded board partition strip 6 is temporarily bonded to the hydrophobic board 8 by glue, so that mortar foot guards 7 can be filled on both sides of the extruded board partition strip 6 to level the surface of the protective layer 4 and to fix the extruded board partition strip 6. The upper surface of the extruded board partition strip 6 is lower than the upper surface of the protective layer 4, the upper surface of the mortar foot guard 7 is level with the upper surface of the protective layer 4, and a gap is formed between the mortar foot guard 7 and the upper end of the extruded board partition strip 6. The gap is filled with sealant 9, and the sealant 9 uses polyurethane sealing paste to fill the gap fully and densely. A plaster layer is formed on the surface of the hydrophobic board 8 to fill the holes on the surface of the hydrophobic board 8 and improve its rigidity and stability.

[0024] The utility model provides a hydrophobic plate 8 at the lower end of the dividing seam 5 to form a drainage channel between the hydrophobic plate 8 and the waterproof layer 2, so that rainwater entering the dividing seam 5 can be discharged along the slope through the drainage channel, greatly reducing the risk of roof leakage.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
