Description

Technical Field

[0002] In house construction, many exhaust pipes, drainage pipes and other pipes need to extend out of the roof. Water seepage is prone to occur at the junction of the pipe and the roof, and this area needs to be waterproofed. The quality of waterproofing directly affects the service life of the building. Therefore, the appropriate roof waterproofing must be strictly and carefully selected in the design.

[0003] The existing sealing of the pipes out of the roof generally adopts the method of hot-melting the waterproof coiled material, pasting it and covering the outer surface of the pipe, and then using a metal clamp to clamp the upper end of the waterproof coiled material. For example, the Chinese patent with the authorization announcement number CN202731130U discloses a waterproof node of the pipe out of the roof, including a pipe protruding from the roof, a pipe sleeve is arranged outside the pipe, a waterproof layer is arranged outside the pipe sleeve, one end of the waterproof layer is arranged on the pipe sleeve, and the other end is extended and arranged on the roof, a metal hoop is arranged around the top of the waterproof layer, and a reinforced fine stone concrete pier is cast outside the waterproof layer. The pier and the metal hoop are on the same horizontal line, and grease is arranged between the metal hoop and the pier. The waterproof layer is directly blocked with the reinforced fine stone concrete pier and the metal hoop is fixed, so that the waterproof layer can provide waterproof protection for the pipe.

[0004] However, this method of using a clamp to hold the waterproof membrane tightly can only form a seal on the outer circumference of the pipe, resulting in poor protection and shortening the waterproof life. Summary of the invention

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0048] According to the following Figure 1-Figure 17 The present invention describes a pre-buried building waterproofing membrane fixing installation structure and a construction method provided in an embodiment of the present invention.

[0049] On the one hand, the present invention provides a pre-buried building waterproofing membrane fixing and installation structure.

[0050] Embodiment 1:

[0051] See also Figure 1The pre-buried building waterproofing membrane fixed installation structure mainly solves the sealing problem at the outlet pipe 1. In the sealing process of the outlet pipe 1, the roof needs to be sealed. Specifically, a hole for accommodating the outer pipe 2 is opened on the roof structure layer 11, and the outer pipe 2 is inserted into the hole. The outlet pipe 1 is sealed and plugged into the outer pipe 2. The fine stone concrete filling part 18 is used to fill the gap between the outer pipe 2 and the structural layer 11. A slope layer 12 is set on the upper surface of the structural layer 11. The inclination of the slope layer 12 is 2°. The closer to the outer pipe 2, the smaller the thickness of the slope layer 12. The thickest part is 30mm. A leveling layer 13 is arranged on the upper surface of the slope layer 12, and the leveling layer 13 is formed by a mixture of water and DP20 dry powder mortar in a ratio of 1:3. A polymer coating waterproof layer 14 is coated on the upper surface of the leveling layer 13, and a main waterproof membrane 15 is laid on the upper surface of the polymer coating waterproof layer 14. The main waterproof membrane 15 is an SCB membrane (SCB membrane is a composite membrane), and an insulation board 16 is laid above the main waterproof membrane 15. The insulation board 16 is an extruded polystyrene board, and a fine stone concrete layer 17 is arranged above the insulation board 16. The thickness of the fine stone concrete layer 17 is 40 mm.

[0052] Combination Figure 1-Figure 4 As shown, in order to ensure the sealing performance of the outlet pipe 1, a pipe waterproofing membrane 8 is arranged on the periphery of the outer pipe 2. Specifically, an annular groove 21 is provided on the outer peripheral surface of the outer pipe 2 near the upper end. The annular groove 21 has an upper surface, a lower surface and an arc-shaped groove bottom. The pipe waterproofing membrane 8 is coated on the periphery of the outer pipe 2, and the upper end of the pipe waterproofing membrane 8 extends into the annular groove 21. The upper end of the pipe waterproofing membrane 8 passes through the lower surface of the annular groove 21 and is coated on the arc-shaped groove bottom. A fine stone concrete layer 17 is arranged on the periphery of the portion of the pipe waterproofing membrane 8 that does not enter the annular groove 21 to protect the pipe waterproofing membrane 8.

[0053] like Figure 6 and Figure 7 As shown, in the above process, in order to ensure that the upper end of the pipe waterproofing membrane 8 can fit the lower surface and the arc-shaped groove bottom, its upper end is cut into a skirt-like structure, and this skirt-like structure is the skirt-like structure 81. The skirt-like structure 81 does not exist at the corner formed by the outer surface of the outer tube 2 and the lower surface of the annular groove 21, but the outer periphery of the lower surface of the annular groove 21 is the pipe waterproofing membrane 8, and the inner periphery is the skirt-like structure 81. Since the diameter of each area in the annular groove 21 is smaller than the outer diameter of the outer tube 2, the individual strip-like waterproofing membranes in the skirt-like structure 81 should cover each other, that is, there is a certain overlap between two adjacent individual strip-like waterproofing membranes, and the overlapping area should be filled with sealant to improve the sealing performance between the two adjacent individual strip-like waterproofing membranes.

[0054] Combination Figure 3 , Figure 4 as well as Figure 7-Figure 9As shown, in order to achieve the sealing of the upper end of the pipeline waterproofing membrane 8, a flat iron clamp 3 is provided here, and the flat iron clamp 3 clamps the skirt structure 81 tightly on the bottom of the arc groove to form the first sealing position of the pipeline waterproofing membrane 8.

[0055] like Figure 4 and Fig.10 As shown, a pressure ring 4 is also provided, and the pressure ring 4 is located on the lower surface of the annular groove 21. The pressure ring 4 is a two-petal structure, which is composed of two 180° arcs to form a circular ring structure. When the pressure ring 4 needs to be placed on the lower surface of the annular groove 21, the two-petal arc structure can be directly placed in the annular groove 21 in sequence.

[0056] Combination Figure 4 and Figure 5 In order to enable the pressure ring 4 to provide vertical pressure to the pipe waterproofing membrane 8 and the skirt structure 81 on the lower surface of the annular groove 21, a vertical pressure component is provided here. The vertical pressure component is installed on the flat iron clamp 3, and a pressure block 5 is provided at the pressure output end of the vertical pressure component. The pressure block 5 is used to provide pressure to the pressure ring 4, so that the pressure ring 4 can press and seal the pipe waterproofing membrane 8 on the lower surface of the annular groove 21 to form a second sealing position of the pipe waterproofing membrane 8.

[0057] Therefore, the embedded building waterproof membrane fixed installation structure provided by the present invention can transform the single sealing position in the prior art into two sealing positions. The second sealing position is a sealing position pressed from top to bottom on the horizontal plane (the lower surface of the annular groove 21). Compared with the method of separately hugging the pipe waterproof membrane 8 on the outside of the pipe in the prior art, the sealing performance is stronger.

[0058] Preferably, the wall thickness of the outer tube 2 is 5 cm, and the depth of the annular groove 21 is 4 cm.

[0059] In addition, in order to facilitate the installation of the vertical pressure assembly, a boss 34 is provided on the outer peripheral surface of the flat iron clamp 3, and the vertical pressure assembly is installed on the boss 34. Preferably, the boss 34 is integrally formed with the flat iron clamp 3, and the thickness of the flat iron clamp 3 is 2 cm.

[0060] Furthermore, the flat iron clamp 3 is a two-petal structure, with connecting ears 31 disposed at both ends thereof, connecting holes 32 being provided on the connecting ears 31, and two opposite connecting holes 32 are fixedly connected by bolts.

[0061] Combination Figure 1-Figure 3 As shown, the pre-embedded building waterproof membrane fixing installation structure provided by the embodiment of the present invention also includes a flexible clamp 19, which is arranged on the vertical pressure component and is used to apply a tightening force to the vertical pressure component. The flexible clamp 19 is similar to a cable tie structure, and a plurality of positioning holes are provided on it. After the flexible clamp 19 is surrounded into a circular structure, two overlapping positioning holes can be connected by bolts to achieve the clamping and locking of the flexible clamp 19.

[0062] Preferably, a through hole 33 for the flexible clamp 19 to pass through is provided on the connecting ear 31, and the width of the through hole 33 is greater than the thickness of the flexible clamp 19, so as to facilitate manual operation of passing the flexible clamp 19 through.

[0063] Combination Figure 4 and Figure 5 As shown, specifically, the above-mentioned boss 34 is arranged at the upper end of the outer circumferential surface of the flat iron clamp 3, and the vertical pressure assembly includes a pressure rod 6, which is arranged in a circular matrix in the annular groove 21, and the upper end of the pressure rod 6 can slide radially along the outer tube 2 on the boss 34; the pressure block 5 is fixed at the lower end of the pressure rod 6, and the lower surface of the pressure block 5 is a slope one, the outer side of the slope one is lower, and the inner side is higher, and the upper surface of the pressure ring 4 is a slope two, the outer side of the slope two is lower, and the inner side is higher. When the pressure block 5 moves centripetally, the relative positions of the slope one and the slope two change, so that when the pressure rod 6 has a tendency to move toward the center of the outer tube 2, the pressure block 5 can also have this tendency, so that the pressure block 5 can generate downward prestress on the pressure ring 4, and the force exerted on the pressure ring 4 is evenly distributed on the pipe waterproofing membrane 8 and the skirt structure 2 81 on the lower surface of the annular groove 21, so that the place is sealed and a second sealing position is formed.

[0064] Preferably, Fig.13 A limiting slider 62 is provided at the upper end of the pressure rod 6, and a limiting sliding groove 341 adapted thereto is provided on the boss 34.

[0065] Combination Figure 2-Figure 5 As shown, the use of the flexible clamp 19 can make the above-mentioned pressure rod 6 tend to move toward the center of the outer tube 2. Specifically, a second through hole 61 is opened on the pressure rod 6, and one end of the flexible clamp 19 passes through the second through holes 61 on multiple pressure rods 6 in sequence and is clamped by bolts. Tightening the flexible clamp 19 can apply a centripetal force with the outer tube 2 as the center to the pressure rod 6.

[0066] Preferably, Fig.11 and Fig.12 As shown, in order to improve the sealing performance of the first sealing position and the second sealing position, an additional waterproof layer 7 is further provided, and the additional waterproof layer 7 is coated on the partial outer surface of the pipeline waterproof membrane 8 located in the annular groove 21. Specifically, the lower side of the additional waterproof layer 7 is also cut into a skirt-like structure to form a skirt-like structure 1 71. The additional waterproof layer 7 is attached to the skirt-like structure 2 81 located on the bottom of the arc groove by hot-melt, and the skirt-like structure 1 71 is attached to the skirt-like structure 2 81 located on the lower surface of the annular groove 21 and the pipeline waterproof membrane 8 by hot-melt.

[0067] Preferably, a building sealant 10 is also provided on the upper surface of the boss 34 .

[0068] Embodiment 2:

[0069] Combination Figure 14-16As shown, the difference from the first embodiment is that the vertical pressure assembly mentioned above includes a vertical rod 91 , a force-bearing rod 93 , a push block 95 and an outer rod 92 .

[0070] The vertical rod 91 is fixed on the boss 34, and the boss 34 is located at the upper end of the outer circumference of the flat iron clamp 3. The force rod 93 is slidably set in the vertical rod 91 along the vertical direction. A force rod 93 is provided in each vertical rod 91, and the force rod 93 is located below the vertical rod 91. The pressure block 5 is fixed to the lower end of the force rod 93 away from the vertical rod 91. The side of the pressure block 5 close to the pressure ring 4 is a plane, and the side of the pressure ring 4 close to the pressure block 5 is a plane. When the upper end of the force rod 93 is subjected to downward pressure, the force rod 93 can have a downward prestress on the pressure block 5.

[0071] In order to enable the stressed rod 93 to be subjected to downward pressure at the upper end, a push block 95 is arranged in the vertical rod 91, and the lower surface of the push block 95 is a slope three. A push rod 94 is fixedly provided on the side of the push block 95 away from the stressed rod 93, and the push rod 94 is exposed outside the vertical rod 91. The outer rod 92 is fixedly arranged at one end of the push rod 94 exposed outside the vertical rod 91. When the outer rod 92 is subjected to radial pressure along the outer tube 2, it can push the push block 95 through the push rod 94, so that the slope three changes its position and applies axial pressure to the stressed rod 93. The stressed rod 93 can form a second seal by applying downward pressure to the pressure block 5 and transmitting it to the pipe waterproof membrane 8 on the lower surface of the annular groove 21 through the pressure ring 4.

[0072] The flexible clamp 19 can apply pressure to the outer rod 92 along the radial direction of the outer tube 2. Specifically, a through hole 921 is provided on the outer rod 92. One end of the flexible clamp 19 passes through the through holes 921 on multiple outer rods 92 in sequence and is clamped by bolts. Tightening the flexible clamp 19 can enable the outer rod 92 to apply pressure to the push block 95 through the push rod 94.

[0073] Embodiment three:

[0074] like Fig.17 The difference between this embodiment and the second embodiment is that a three-dimensional seal is performed on the pipe waterproofing membrane 8 in the annular groove 21, that is, the arc groove bottom, lower surface and upper surface of the annular groove 21 are all sealed. Specifically, the upper end of the pipe waterproofing membrane 8 extends to the upper surface of the annular groove 21, and a pressure ring 4 is provided on the upper surface and the lower surface of the annular groove 21. The boss 34 is located in the middle of the outer circumference of the flat iron clamp 3. Two force-bearing rods 93 are provided in each vertical rod 91. The two force-bearing rods 93 are respectively located at the upper and lower parts of the vertical rod 91. A pressure block 5 is fixed to one end of the two force-bearing rods 93 away from the vertical rod 91. The upper and lower surfaces of the push block 95 are provided with slopes three, and each slope three corresponds to a force-bearing rod 93. Fig.17In the state shown, the push block 95 moves to the left, the upper force-bearing rod 93 can apply upward pressure to the upper pressure block 5 and transmit it to the pipe waterproof membrane 8 located on the upper surface of the annular groove 21 through the pressure ring 4, and the lower force-bearing rod 93 can apply downward pressure to the lower pressure block 5 and transmit it to the pipe waterproof membrane 8 located on the lower surface of the annular groove 21 through the pressure ring 4, so that the upper surface forms a third sealing position and the lower surface forms a second sealing position.

[0078] Step 3: Place the pressure ring 4 in the annular groove 21, and use the flat iron clamp 3 to hold the skirt structure 81 tightly on the arc-shaped groove bottom of the annular groove 21 (such as Fig.11 One of the flat iron clamps 3 is in a tightly clamped state), forming a first sealing position;

[0079] Step 4: Use the flexible clamp 19 to hold the vertical pressure assembly tightly, so that the vertical pressure assembly generates pressure on the pressing block 5, and the pressing block 5 applies pressure to the skirt structure 81 located on the lower surface of the annular groove 21 to form a second sealing position of the pipeline waterproofing membrane 8, forming Figure 2 Status shown.

[0080] In a third aspect, the present invention further provides a construction method, which is applied to the pre-buried building waterproof membrane fixed installation structure in the above-mentioned embodiment 3, comprising the following steps:

[0081] Step 1: Cut the waterproof membrane into the required length, and cut its upper and lower ends into a skirt-like structure;

[0082] Step 2: The waterproofing membrane is adhered to the outer periphery of the outer tube 2 by hot-melt method to form a pipeline waterproofing membrane 8, the upper skirt structure of the pipeline waterproofing membrane 8 forms a second skirt structure 81, and the second skirt structure 81 is adhered to the upper surface, lower surface and arc groove bottom of the annular groove 21;
