Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, and more specifically, to a waterproof structure at the position of a roofing plate and an eaves ditch. Background Art

[0002] Metal roofing uses metal sheets as roof covering materials, integrating structural and waterproofing functions. Its parts are standardized and mass-produced in factories, and are available in a variety of forms and specifications to meet different waterproofing, thermal insulation and service life requirements. Metal roofing adopts prefabricated construction, and has the advantages of light weight, large span and fast construction cycle, so it is widely used in factories, warehouses and simple houses. Usually, metal roofing uses corrugated steel sheets as roofing sheets. Corrugated steel sheets are steel sheets that are formed by cold bending to form periodic peaks and troughs, and the surface is usually coated or plated.

[0003] In the prior art, waterproofing rolls are usually laid on the surface of the corrugated steel sheet and the eaves gutter respectively, leaving the end surface of the corrugated steel sheet empty; then a separate small piece of waterproofing roll is used for cutting and repairing. The separate sheet-shaped waterproofing roll covers the end surface of the corrugated steel sheet and overlaps the waterproofing roll fixed on the roofing sheet and the waterproofing roll on the eaves gutter. In order to completely block the end surface of the corrugated steel sheet, the separate waterproofing roll needs to be folded and fixed multiple times, which has low construction efficiency, obvious wrinkles and unsightly appearance, and increases the potential risk of leakage at the corner.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a waterproof structure for roof panels and eaves gutters.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Waterproof structure of roof panels and gutter, refer to Figures 1 to 4 As shown, it includes a roofing panel body 1 and a gutter body 5, a transition plate 2 is fixedly installed at the bottom end of the roofing panel body 1, and the end of the transition plate 2 is located above the gutter body 5, the surfaces of the roofing panel body 1 and the transition plate 2 are both provided with crests and troughs, and the crests and troughs on the surface of the roofing panel body 1 are aligned with the crests and troughs on the surface of the transition plate 2, the top surface of the transition plate 2 is provided with a water-blocking component 3 for sealing the gap between the roofing panel body 1 and the transition plate 2, a diversion component 4 is provided below the transition plate 2, and an anti-overflow component 6 is installed at the bottom of the diversion component 4.

[0021] In the above embodiment: during construction, the transition plate 2 is installed at the end of the roofing panel body 1, and the end of the transition plate 2 is located above the gutter body 5, ensuring that rainwater can flow from the roofing panel body 1 to the inside of the transition plate 2, and then be diverted to the gutter body 5 to achieve smooth drainage. The joint between the roofing panel body 1 and the transition plate 2 is then sealed by the water-blocking component 3 to prevent rainwater from flowing from the rear end of the transition plate 2. At the same time, the water flowing out from the rear side of the transition plate 2 is diverted by the diversion component 4, so that rainwater can flow into the gutter body 5. The joint between the diversion component 4 and the gutter body 5 can be blocked by the anti-overflow component 6 to prevent rainwater from overflowing. In use, the effect of effective waterproofing between the roofing panel and the gutter is achieved, ensuring the smooth flow of rainwater from the gutter. Compared with the construction using coiled materials, it is more convenient and efficient, and has good practicality.

[0022] refer to Figure 1 , Figure 2 As shown, the water-blocking assembly 3 includes a water-swellable waterstop strip 301 and a water retaining strip 302, and the water-swellable waterstop strip 301 and the water retaining strip 302 are both fixedly connected to the top surface of the transition plate 2, and the water retaining strip 302 and the water-swellable waterstop strip 301 are both in contact with the bottom surface of the roofing board body 1, and the water retaining strip 302 is made of rubber.

[0023] In the above embodiment: when the roofing panel body 1 and the transition plate 2 are pressed together and installed, the water-swellable waterstop strip 301 and the water retaining strip 302 will be squeezed, and the water-swellable waterstop strip 301 and the water retaining strip 302 are used to seal the contact position between the two to prevent rainwater from moving to the rear side. If rainwater passes through the water retaining strip 302 and is released from the water-swellable waterstop strip 301, the water-swellable waterstop strip 301 will expand, further blocking the gap between the roofing panel body 1 and the transition plate 2, thereby playing a double-layer water-stopping role.

[0024] refer to Figure 1 , Figure 2 , Figure 3 As shown, the guide assembly 4 includes a connecting piece 401, and the connecting piece 401 is fixedly connected to the side of the transition plate 2, the surface of the connecting piece 401 is attached to the guide plate 402, the surface of the guide plate 402 is threadedly connected with a positioning bolt 403, and the positioning bolt 403 is threadedly connected to the guide plate 402.

[0025] In the above embodiment: after the transition plate 2 is installed, the guide plate 402 is fixed by using the positioning bolts 403. When rainwater flows out from the rear end of the transition plate 2, the rainwater will flow to the inside of the guide plate 402, and then guide the rainwater to the eaves gutter body 5, thereby playing a bottom-up waterproof role for the water-blocking component 3.

[0026] refer to Figure 1 , Figure 4 As shown, the anti-overflow component 6 includes a water baffle 601, and the water baffle 601 is fixedly connected to the bottom of the connecting plate 401, and the back of the water baffle 601 is fixedly connected with a clamping strip 602, and the clamping strip 602 is made of rubber material, and the clamping strip 602 fits the inner wall of the eaves gutter body 5.

[0027] In the above embodiment: during the installation of the guide assembly 4, the compression strip 602 is pressed against the inner wall of the gutter body 5, thereby reducing the gap between the water retaining plate 601 and the inner wall of the gutter body 5. When rainwater from the surface of the transition plate 2 falls onto the gutter body 5, it is difficult for rainwater to overflow from the gap between the water retaining plate 601 and the gutter body 5, thereby ensuring that rainwater flows smoothly along the gutter body 5.

[0028] refer to Figure 1 , Figure 2 As shown, a fastening bolt 7 is threadedly connected at the crest position of the roofing board body 1 , a threaded hole 8 is opened at the crest position of the transition plate 2 , and the threaded hole 8 is threadedly connected to the fastening bolt 7 .

[0029] In the above embodiment: by arranging a plurality of sets of fastening bolts 7 and threaded holes 8 at the wave crest positions of the roofing panel body 1 and the transition plate 2, the roofing panel body 1 and the transition plate 2 are stably connected to avoid separation of the two. When maintenance and replacement are required, the fastening bolts 7 can be removed to facilitate replacement of the transition plate 2.

[0030] refer to Figure 1 , Figure 2 As shown, there are two groups of connecting pieces 401 and two groups of positioning bolts 403, and the bottom of the inner wall of the guide plate 402 is in an inclined state with the front lower and the rear higher.

[0031] In the above embodiment: by setting two groups of connecting plates 401 and positioning bolts 403, the guide plate 402 is supported and fixed on the left and right sides, so that the guide plate 402 remains stable, and by setting the guide plate 402 to an inclined state, rainwater flowing back from the rear end of the transition plate 2 to the inside of the guide plate 402 can flow smoothly to the front side into the inside of the gutter body 5.

[0032] Working principle:

[0033] During construction, the transition plate 2 is installed at the end of the roof panel body 1, and the end of the transition plate 2 is placed above the gutter body 5 to ensure that rainwater can flow from the roof panel body 1 to the inside of the transition plate 2, and then be diverted to the gutter body 5 to achieve smooth drainage. The joint between the roof panel body 1 and the transition plate 2 is then sealed by the water-blocking component 3 to prevent rainwater from flowing from the rear end of the transition plate 2. At the same time, the water flowing out from the rear side of the transition plate 2 is diverted by the diversion component 4 so that the rainwater can flow into the inside of the gutter body 5. The anti-overflow component 6 can block the joint between the diversion component 4 and the gutter body 5 to prevent rainwater from overflowing.
