Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, specifically to a metal sealing strip for the end of TPO waterproof membrane. Background Technology

[0002] TPO waterproof membrane is a high-performance building waterproofing material widely used for waterproofing and damp-proofing in roofs, basements, and other projects. Currently, parapet walls and photovoltaic supports are typically installed on flat roofs, and TPO waterproof membrane is generally laid on the surface of these structures. However, during actual construction and use, TPO membrane is prone to curling, warping, or even detachment at the joints, such as the top of the parapet wall and the base of the photovoltaic support, due to thermal expansion and contraction, wind force, or insecure fixing. This can lead to waterproofing layer failure and leakage problems. To address this issue, pressure strips are currently placed at the joints of the TPO membrane to tighten the edges. However, most of these pressure strips are currently applied using adhesive, and over time, the adhesive can age and fail, causing the pressure strip to detach. Utility Model Content

[0003] This utility model provides a metal sealing strip for TPO waterproof membrane, which can overcome some or all the defects of the prior art.

[0004] According to the present invention, a TPO waterproof membrane sealing metal strip includes: a strip body, the strip body including a connecting part, one end of the connecting part being bent to form a bent part, the bent part and the membrane together forming a sealing area for adhesive to enter; a screw is also provided at the connecting part, the screw being used to fix the connecting part and the membrane to the wall.

[0005] With this utility model, when laying TPO waterproof membrane, construction workers first lay the membrane on the parapet wall and photovoltaic support. After the membrane is laid, the pressure strip is pressed on the end of the membrane. When using the pressure strip, the adhesive layer of the pressure strip is first attached to the upper end of the membrane, and the connecting part of the pressure strip extends 0.5-1 cm out of the membrane to form a blocking part. Then, the pressure strip is connected end to end along the length of the parapet wall or the periphery of the photovoltaic support. After the pressure strip is connected, screws are inserted through the pressure strip and the membrane into the wall or photovoltaic support to further fix the pressure strip and prevent it from falling off after long-term use.

[0006] After the pressure strip screws are installed, pour waterproof adhesive into the sealing area. The waterproof adhesive will further seal the gaps between the roll material and the wall or photovoltaic bracket. At the same time, in conjunction with the pressure strip, the sealing performance of the pressure strip is improved.

[0007] Because the connecting part of the pressure strip extends 0.5 to 1 cm out of the roll material, forming a blocking part, the waterproof adhesive enters the sealing area and bonds the blocking part and the bending part to the wall or photovoltaic bracket, thereby better preventing the bending part and the connecting part from separating from the wall or photovoltaic bracket.

[0008] Preferably, the end of the connecting portion away from the bending portion is wound inward to form a winding portion.

[0009] With this invention, after the construction workers have fixed the screws, they can fold the lower end of the connecting part upwards. The rolled-up part can cover the edge of the TPO roll material, preventing the roll material from warping due to wind or thermal expansion and contraction, thus avoiding the formation of a water seepage channel. At the same time, when pasting the pressure strip, first straighten the lower end of the pressure strip to 90 degrees, and then fold the lower end of the pressure strip upwards when pasting the pressure strip. The folded rolled-up part can cover the screw nut, thereby protecting the nut and reducing damage to the nut from external factors.

[0010] Preferably, the angle between the bent portion and the connecting portion is 30 to 45 degrees.

[0011] This invention avoids an excessively large cutting angle between the bending part and the connecting part, which would cause the waterproof adhesive to overflow from the sealing area when it is poured.

[0012] Preferably, the main body of the pressure strip is made of stainless steel.

[0013] This invention provides a stainless steel structure with high strength and corrosion resistance, which can extend the service life of the pressure strip.

[0014] Preferably, the thickness of the connecting part is 1 to 1.5 mm.

[0015] Through this utility model, the tensile strength of a 1.0mm thick 304 stainless steel strip can reach 800N / 50mm, which meets the requirements for fixing the roof edge. The 1.5mm thickness can withstand a level 12 typhoon. Construction workers can choose strips of different thicknesses according to different environments. The 0.5~1.5mm thickness makes it easy for construction workers to bend the strips.

[0016] Preferably, the width of the main body of the molding strip is 3.5 to 4 centimeters.

[0017] This invention offers a more economical material option for the 3.5 cm thick strip body, making it suitable for space-constrained areas such as narrow parapet walls, ideal for indoor use. The 4 cm thick strip body provides a wider sealing surface and greater construction tolerance. It is applicable to most roofs, photovoltaic supports, and high-rise buildings, allowing construction workers to choose the appropriate option based on their environment.

[0018] Preferably, the main body of the molding strip is 20-30 cm long.

[0019] With this invention, when construction workers fix the pressure strip with screws, the screws are fixed not only at the pressure strip itself but also at the connection point of adjacent pressure strips; however, it is difficult to ensure that the screws can fix the pressure strip if it is too long.

[0020] Preferably, the width of the bent portion is 0.5 to 1 cm.

[0021] This invention avoids the problem of excessively wide bends, which would lead to excessive amounts of waterproof adhesive being filled in the sealing area, resulting in waste of waterproof adhesive.

[0022] Preferably, the width of the winding section is 1-1.5 cm.

[0023] This invention enables the winding section to cover the screw nut, thus protecting the nut. Attached Figure Description

[0025] Figure 2 This is a schematic diagram of the installation position of the pressure strip body in Example 1. Detailed Implementation

[0026] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0027] Example 1

[0028] like Figure 1-2 As shown, this embodiment provides a metal strip for sealing the end of a TPO waterproof membrane, including a strip body 100. The strip body 100 includes a connecting part 110. One end of the connecting part 110 is bent to form a bent part 102. The bent part 102 and the membrane 1 together constitute a sealing section 104 for the entry of adhesive. A screw is also provided at the connecting part 110 for fixing the connecting part 110 and the membrane 1 to the wall.

[0029] In this embodiment, when laying TPO waterproof membrane, the construction workers first lay membrane 1 on the parapet wall and photovoltaic support. After the membrane 1 is laid, the pressure strip is pressed on the end of the membrane 1. When using the pressure strip, the adhesive layer of the pressure strip is first attached to the upper end of the membrane 1, and the connecting part 110 of the pressure strip extends 10.5 to 1 cm out of the membrane 1 to form the blocking part 101. Then, the pressure strip is connected end to end along the length of the parapet wall or the periphery of the photovoltaic support. After the pressure strip is connected, the screw is inserted into the wall or photovoltaic support through the pressure strip and the membrane to further fix the pressure strip and prevent it from falling off after long-term use.

[0030] After the pressure strip screws are installed, pour waterproof adhesive into the sealing area 104. The waterproof adhesive will further seal the gap between the roll material 1 and the wall or photovoltaic bracket. At the same time, in conjunction with the pressure strip, the sealing performance of the pressure strip is better improved.

[0031] Since the connecting part 110 of the pressure strip extends 10.5~1 cm out of the roll material, it forms a blocking part 101. The waterproof adhesive enters the sealing area 104 and bonds the blocking part 101 and the bending part 102 to the wall or photovoltaic bracket, thereby better preventing the bending part 102 and the connecting part 110 from separating from the wall or photovoltaic bracket.

[0032] In this embodiment, the end of the connecting portion 110 away from the bending portion 102 is rolled inward to form a winding portion 103.

[0033] In this embodiment, after the construction personnel have fixed the screws, they fold the lower end of the connecting part 110 upwards. The retractable part 103 can cover the edge of the TPO roll material, preventing the roll material from warping due to wind or thermal expansion and contraction, thus forming a water seepage channel. At the same time, when pasting the pressure strip, the lower end of the pressure strip is first straightened to 90 degrees. Then, when pasting the pressure strip, the lower end of the pressure strip is folded upwards. The folded retractable part 103 can cover the nut of the screw, thereby protecting the nut and reducing damage to the nut from external factors.

[0034] In this embodiment, the included angle between the bent portion 102 and the connecting portion 110 is 30 to 45 degrees.

[0035] This embodiment avoids an excessively large cutting angle between the bending part 102 and the connecting part 110, which would cause the waterproof adhesive to overflow from the sealing area 104 when it is poured.

[0036] In this embodiment, the pressure strip body 100 is made of stainless steel.

[0037] Through this embodiment, the stainless steel material has strong structural strength and strong corrosion resistance, which can extend the service life of the pressure strip.

[0038] In this embodiment, the thickness of the connecting part 110 is 1~1.5 mm.

[0039] Through this embodiment, the tensile strength of a 1.0mm thick 304 stainless steel strip can reach 800N / 50mm, which meets the requirements for fixing the roof edge. The 1.5mm thickness can withstand a level 12 typhoon. Construction workers can choose strips of different thicknesses according to different environments. The 0.5~1.5mm thickness makes it easy for construction workers to bend the strips.

[0040] In this embodiment, the width of the pressure strip body 100 is 3.5~4 cm.

[0041] In this embodiment, the 3.5 cm thick strip body 100 is more economical in terms of materials and is suitable for space-constrained nodes, such as narrow parapet walls, which are suitable for indoor use; the 4 cm thick strip body 100 has a wide sealing surface, strong wind resistance, and high construction tolerance; it is suitable for most roofs, photovoltaic supports, and high-rise buildings; construction personnel can choose to use it according to different environments.

[0042] In this embodiment, the length of the pressure strip body 100 is 20~30 cm.

[0043] In this embodiment, when the construction worker fixes the pressure strip with screws, the screws are fixed not only at the pressure strip itself, but also at the connection point of adjacent pressure strips; however, it is difficult to ensure that the screws can fix the pressure strip if it is too long.

[0044] In this embodiment, the width of the bent portion 102 is 0.5 to 1 cm.

[0045] This embodiment avoids the bending portion 102 being too wide, which would result in excessive filling of the sealing section 104 with waterproof adhesive, leading to waste of waterproof adhesive.

[0046] In this embodiment, the width of the winding section 103 is 1-1.5 cm.

[0047] This embodiment enables the winding section 103 to cover the screw nut and protect the nut.

[0048] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0049] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
