[0033] Please refer to the reference. Figure 1 and Figure 2 According to an embodiment of the present invention, the waterproof membrane 3 at the end structure of the parapet wall 2 includes a roof 1, a parapet wall 2, a waterproof membrane 3, and tie bolts 4. The parapet wall 2 is located at the edge of the roof 1. The side of the parapet wall 2 facing the roof 1 is the inner side 21, and the side of the parapet wall 2 away from the roof 1 is the outer side 22. The parapet wall 2 has a through hole that passes through the inner side 21 and the outer side 22. The waterproof membrane 3 is laid on the roof 1 and the inner side 21, and at least partially folded to the outer side 22. The part of the waterproof membrane 3 folded to the outer side 22 is the exposed part 31. The exposed part 31 has a fixing hole, which is correspondingly set with the through hole. One end of the tie bolt 4 passes through the fixing hole and is connected to the waterproof membrane 3. The other end of the tie bolt 4 moves through the through hole.
[0034] According to the embodiment of this utility model, the waterproof membrane 3 is terminated at the parapet wall 2 by means of tie bolts 4 passing through the parapet wall 2. One end of the tie bolts 4 located on the outside of the parapet wall 2 can be connected and fixed to the waterproof membrane 3. In this way, by tightening the tie bolts 4 on the inside of the parapet wall 2, the waterproof membrane 3 can be terminated and fixed on the outside of the parapet wall 2, which solves the problem of difficulty in nailing on the outside of the parapet wall 2 and improves the convenience of fixing the waterproof membrane 3.
[0035] The following describes the installation and fixing process of waterproof membrane 3:
[0036] I. Preparations before construction:
[0037] 1. Material Preparation: Based on the thickness of the parapet wall 2, waterproofing requirements, and the need for fixing the waterproof membrane, select appropriate specifications of tie bolts 4, such as tie bolts 4 with a diameter of 8-12mm, and matching nuts and washers (such as metal flat washers and spring washers). Prepare sealing materials, such as water-swellable sealant and silicone weather-resistant sealant, for sealing and waterproofing between the tie bolts 4 and the wall. Also prepare metal pressure strips 8 for fixing the waterproof membrane 3, made of aluminum alloy or stainless steel, with a thickness of 1-2mm.
[0038] 2. Tool Preparation: Equip yourself with an electric drill and drill bits of the appropriate diameter, such as alloy drill bits 1-2mm larger than the bolt diameter, to ensure precise and efficient drilling. Prepare wrenches, screwdrivers, and other installation tools, as well as measuring tapes and levels for measurement and positioning to ensure accurate construction positioning.
[0039] 3. Base Treatment: The base surface of Parapet Wall 2 should be flat, firm, and free from defects such as looseness, sand, or peeling. Use a broom, small shovel, or other tools to clean the dust and debris from the surface of Parapet Wall 2. If there is oil stains, clean them with organic solvents. Repair any cracks, holes, or other defects on the base surface with cement mortar or special repair materials to make the base surface flat and smooth, meeting the requirements for drilling and waterproofing construction.
[0040] II. Drilling Construction:
[0041] 1. Measurement and Positioning: Based on the design plan for fixing the waterproof membrane 3, accurately measure and mark the drilling positions at the locations where the waterproof membrane 3 needs to be fixed on the parapet wall 2 using a tape measure and level. The drilling spacing is generally controlled between 300-500mm, evenly distributed to ensure that the waterproof membrane 3 is firmly fixed and under balanced stress.
[0042] 2. Drilling Operation: Using an electric drill, drill holes perpendicular to the surface of parapet wall 2 according to the marked positions. Drill through parapet wall 2 according to its thickness to ensure that the tie bolts 4 can be fully inserted and that both ends have sufficient length for installing nuts and washers. During drilling, keep the electric drill stable and avoid tilting the drill or drilling holes with excessive diameter.
[0043] 3. Hole cleaning: After drilling, immediately use a blower, brush and other tools to clean the dust and debris in the hole to ensure that the hole is clean and to create good conditions for the subsequent installation and sealing of tie bolt 4.
[0044] III. Installation of tie bolt 4:
[0045] 1. Bolt Insertion: Apply water-swellable sealant evenly inside the through hole, then slowly insert the tie bolt 4 into the through hole, ensuring the sealant is evenly distributed between the tie bolt 4 and the hole wall. Ensure that the lengths of both ends of the tie bolt 4 protruding from the parapet wall 2 are consistent, and meet the requirements for installing nuts and washers.
[0046] 2. Fixing and Sealing: Install metal flat washers and spring washers at both ends of the tie bolt 4 in sequence, and then tighten the nuts. The elasticity of the spring washers enhances the stability of the tie bolt 4 and prevents the nuts from loosening. Apply silicone weather-resistant sealant between the nut and the surface of the parapet wall 2 to form a sealing layer and prevent rainwater from seeping in. For areas with high waterproofing requirements, sealing treatment can be applied to both the inside and outside of the tie bolt 4, such as by attaching a waterproof membrane 3 reinforcement layer.
[0047] 3. Membrane Fixing: Fold the waterproof membrane 3 up to the outside of the parapet wall 2, covering the tie bolt 4 on the inside of the parapet wall 2. Place the metal strip 8 at the edge of the waterproof membrane 3, covering the junction of the waterproof membrane 3 and the parapet wall 2. Tighten the nuts on the tie bolts 4 to press the metal strip 8 firmly onto the waterproof membrane 3, thus achieving a secure fixation of the waterproof membrane 3.
[0048] like Figure 2 As shown, according to one embodiment of the present invention, a pressure strip 8 is provided at one end of the tie bolt 4 on the outer side 22. The pressure strip 8 is located on the side of the waterproof membrane 3 away from the parapet wall 2 and presses the waterproof membrane 3 against the parapet wall 2. It can be understood that the pressure strip 8 can increase the contact area with the waterproof membrane 3, improve the fixing stability of the waterproof membrane 3, and prevent the waterproof membrane 3 from curling up.
[0049] According to one embodiment of the present invention, an elastic washer is provided between the pressure strip 8 and the waterproof membrane 3. In this way, the elasticity of the spring washer is used to enhance the stability of the tie bolt 4 and prevent the nut from loosening.
[0050] Please refer to the reference. Figures 3 to 5 According to one embodiment of the present invention, the termination structure of the waterproof membrane 3 at the parapet wall 2 includes a snap-on plate 5, which is fastened to the parapet wall 2 and presses the waterproof membrane 3 tightly. By fastening the top surface of the parapet wall 2 with the snap-on plate 5, it is beneficial to press the waterproof membrane 3 located on the outer and inner sides of the parapet wall 2 tightly.
[0051] According to one embodiment of the present invention, the buckle plate 5 is provided with an extension 51, which is located on the outer side 22 of the parapet wall 2. The length of the extension 51 in the height direction is greater than or equal to the length of the exposed part 31 in the height direction.
[0052] It should be noted that the waterproof membrane 3 is directly exposed on the outside of the parapet wall 2, affecting the overall aesthetics of the building. For some buildings with high aesthetic requirements, the membrane at the top of the parapet wall 2 is directly exposed to the outdoor environment, subjected to direct sunlight, wind and rain erosion, etc., accelerating the aging and damage of the waterproof membrane 3. Especially under extreme climatic conditions such as high temperature and low temperature, the performance of the waterproof membrane 3 will be more affected, shortening its service life. To address the above problems, the extension 51 of the snap-on panel 5 can cover the exposed waterproof membrane 3, improving the building's aesthetics.
[0053] According to one embodiment of this utility model, the extension portion 51 has a mounting hole, one end of the tie bolt 4 passes through the mounting hole and is connected to the extension portion 51. That is to say, the tie bolt can be used to fix the end of the waterproof membrane 3, and can also fix the buckle plate 5 to improve the installation stability of the buckle plate 5.
[0054] According to one embodiment of this utility model, the side of the buckle plate 5 facing the parapet wall 2 is provided with a reinforcing rib 52. It is understood that the buckle plate 5 only has one fixing point on the outside of the parapet wall 2, so there is a risk of it being blown off by the wind. Therefore, metal ribs are added to the inside of the buckle plate 5 as reinforcing ribs 52 to increase its bending resistance. Optionally, the buckle plate 5 can be made of aesthetically pleasing materials such as aluminum-magnesium-manganese steel.
[0055] According to one embodiment of the present invention, the waterproof membrane 3 has a double-layer structure to ensure waterproof effect.
[0056] According to one embodiment of the present invention, a first coating reinforcement layer 6 is applied to the connection between the roof 1 and the parapet wall 2 to enhance the waterproofing effect at the connection between the roof 1 and the parapet wall 2.
[0057] According to one embodiment of the present invention, the roof 1 is coated with a second coating reinforcement layer 7, which at least partially overlaps with the first coating reinforcement layer 6, so as to avoid the situation where the coating reinforcement layer does not completely cover the roof 1.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
