Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a roofing water drain port waterproof construction, including reinforced concrete structural layer 1, the vertical pipe in water 5 that sets up in reinforced concrete structural layer 1 that runs through, laid the heat preservation 2 of being made by the polyphenyl board on pipe in water 5 and reinforced concrete structural layer 1's surface, cement mortar screed-coat 3 has been pour on heat preservation 2's surface, cement mortar screed-coat 3 top surface has been laid waterproof roll material layer 4, waterproof roll material layer 4 extends to on the inner wall of pipe in water 5 open ends, waterproof roll material layer 4 passes through the hot bonding of sealant with pipe in water 5's inner wall. In this embodiment, the downpipe 5 includes a circular truncated cone section 51 with a gradually decreasing radius from top to bottom and a straight pipe section 52 disposed below the circular truncated cone section 51, the circular truncated cone section 51 and the straight pipe section 52 are integrally formed, a holding pipe 6 adapted to the circular truncated cone section 51 is inserted into the circular truncated cone section 51, the waterproof coiled material layer 4 is sandwiched between the inner wall of the circular truncated cone section 51 and the holding pipe 6, and the holding pipe 6 is provided with a fastening device 7 fixed to the downpipe 5. Because the radius of the circular truncated cone section 51 is gradually reduced from top to bottom, when the waterproof coiled material layer 4 is clamped between the inner wall of the circular truncated cone section 51 and the abutting pipe 6, the abutting pipe 6 is pushed downwards with force, the pressure action effect of the abutting pipe 6 on the circular truncated cone section 51 is stronger and stronger, the abutting pipe 6 is fixed with the downpipe 5 through the fastening device 7, and therefore the waterproof coiled material layer 4 can be tightly pressed on the inner wall of the circular truncated cone section 51. Therefore, the tight supporting pipe 6 can firmly fix the connection place of the waterproof coiled material layer 4 and the downpipe 5, and the sealing effect is good.
Referring to fig. 2, in order to facilitate the installation and fixation of the abutting pipe 6, three layers of sawtooth-shaped convex edges 8 are integrally formed on the inner wall portion of the circular truncated cone section 51 below the waterproof roll material layer 4, the cross sections of the convex edges 8 are right-angled triangles, the bottom edges of the convex edges 8 are right-angled edges, and three layers of sawtooth-shaped grooves 9 matched with the convex edges 8 are formed in the surrounding mode on the outer wall of the abutting pipe 6. Under the effect of bead 8, support tight pipe 6 and pipe in the water 5 chucking back, support tight pipe 6 just can't follow vertical ascending direction and remove, the effectual fixed effect of having guaranteed between tight pipe 6 and the pipe in the water 5 of supporting. In this embodiment, in order to facilitate the installation of the abutting pipe 6, the arrangement of the rib 8 is prevented from preventing the abutting pipe 6 from being completely clamped into the downpipe 5, the horizontal width of the rib 8 is preferably 2mm, and a rubber layer is adhered to the outer wall of the abutting pipe 6.
With reference to fig. 2, the arrangement of the ribs 8 and grooves 9 to some extent provides a fixing effect for the abutment pipe 6 and the downpipe 5, but cannot be used as a primary fixing means, and therefore, a further refinement is made to the fixing between the two: the inner diameter of the straight pipe section 52 is smaller than the inner diameter of the bottom surface of the circular table section 51, the inner wall of the bottom end of the abutting pipe 6 is provided with a bearing ring 10 with the inner diameter identical to that of the straight pipe section 52, the bearing ring 10 and the abutting pipe 6 are integrally manufactured, the inner wall of the top end of the straight pipe section 52 is provided with an external thread 11, the fastening device 7 comprises a threaded pipe 71 which penetrates through the bottom end of the abutting pipe 6 and is in threaded connection with the straight pipe section 52 through the external thread 11, and an abutting ring 72 which is integrally manufactured with the threaded pipe 71 and abuts against the top surface. When the threaded pipe 71 is continuously rotated towards the bottom end of the straight pipe section 52, the threaded pipe 71 drives the abutting ring 72 to vertically move downwards, so that the abutting ring 10 is tightly pressed on the top surface of the straight pipe section 52 through the abutting ring 72, and the movement of the abutting pipe 6 is limited. The fastening device 7 is simple in structure, good in fixing effect and high in practicability. Preferably, in order to improve the connection effect between the abutting pipe 6 and the fastening device 7, the sealant 12 is coated between the top surface of the abutting ring 72 and the inner wall of the abutting pipe 6, and the vertical section of the sealant 12 is in an inverted-splayed shape, so that the rainwater can fall conveniently. When it rains, water may collect on the top surface of the abutting pipe 6 and permeate between the abutting pipe 6 and the waterproof roll layer 4, thereby reducing the service life of the waterproof roll layer 4. Therefore, the top surface of the caulking pipe 6 is provided with a downward slope in a direction toward the axis thereof to solve this problem.
Referring to fig. 2, in order to further improve the abutting effect of the abutting pipe 6 on the waterproof roll material layer 4 and improve the sealing effect of the abutting pipe, a metal extrusion ring 13 is bonded on the outer wall of the top end of the abutting pipe 6, the cross section of the extrusion ring 13 is triangular with a certain radian, and the tip of the extrusion ring 13 abuts against the waterproof roll material layer 4. Because waterproof roll material layer 4 is softer, can take place certain deformation under the extrusion, when supporting tight pipe 6 and waterproof roll material layer 4 and support tightly, extrusion ring 13 can increase the local deformation degree in waterproof roll material layer 4, has further promoted and has supported tight pipe 6 to the fixed effect on waterproof roll material layer 4, and then has promoted the sealed effect of this roofing mouth of falling water waterproof construction. Furthermore, a limiting ring 14 is integrally formed on one surface of the bottom end of the waterproof roll material layer 4, which is far away from the downpipe 5, a limiting groove 15 matched with the limiting ring 14 for use is formed in the outer wall of the abutting pipe 6, and the main function of the limiting device is to limit the waterproof roll material layer 4 to move after being fixed.
The implementation principle of the embodiment is as follows: when the pipe orifice structure is installed, firstly, the waterproof roll material layer 4 is well bonded with the downpipe 5, then the abutting pipe 6 is placed in the circular truncated cone section 51, and the circular truncated cone section is pushed downwards forcibly, so that the limiting ring 14 and the convex rib 8 are sequentially clamped into the limiting groove 15 and the groove 9; then, a threaded pipe 71 is placed in the abutting pipe 6, the threaded pipe 71 is rotated to enable the abutting ring 72 to abut against the receiving ring 10, and finally, the sealant 12 is coated between the top surface of the abutting ring 72 and the inner wall of the abutting pipe 6.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
