Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a method for waterproofing steel structure roof walls. Background Technology
[0002] The parapet wall, also known as the low wall surrounding the roof, serves not only for safety but also for roof waterproofing. Regulations stipulate a minimum height of 1.2 meters. Steel structure roofs are widely used in various large-span factory buildings due to their lightweight, quick construction, and the elimination of the need for formwork and concrete pouring. However, rainwater can easily seep into the gap between the steel structure roof and the parapet wall. This water then seeps into the building and, over time, can cause leaks. Therefore, waterproofing the steel structure roof walls is essential.
[0003] Currently, during the construction of steel roofs, perlite integrated panels need to be laid on the roof to achieve a heat insulation effect. When installing the perlite integrated panels, connectors are typically used to reliably connect the steel secondary beams to the wire mesh on the outside of the perlite integrated panels. However, this method leaves the perlite integrated panels suspended underneath, making the connection between the panels and the walls prone to sinking and deformation, creating gaps. This results in inadequate waterproofing at the connection between the steel structure roof and the roof walls, posing a risk of leakage.
[0004] Therefore, there is an urgent need for a waterproofing construction method for steel structure roofs and walls to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a waterproofing construction method for steel structure roof walls, so as to solve the problem of rainwater leakage caused by the loose connection between the steel structure roof and the roof wall.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A method for waterproofing steel structure roof walls includes the following steps:
[0008] Step S1: Install connectors between the wall and the steel beam;
[0009] Step S2: Lay a layer of steel plate on the steel beam and purlin, and fix the steel plate to the steel beam, the purlin and the connector;
[0010] Step S3: Lay a first moisture-proof layer on the steel plate and extend the first moisture-proof layer to the wall;
[0011] Step S4: Lay the perlite integrated board on the first moisture-proof layer, and then lay the second moisture-proof layer on the perlite integrated board.
[0012] Preferably, in step S1, the connector is an angle iron, with the first side of the angle iron fitting against the wall and the second side of the angle iron welded to the steel beam.
[0013] Preferably, in step S1, the first end of the angle iron is sealed with sealant between it and the wall.
[0014] Preferably, in step S2, one end of the steel plate is placed on the second side of the angle iron and one end of the steel plate is welded to the first side of the angle iron.
[0015] Preferably, in step S2, one end of the steel plate is welded to the first side of the angle iron and then sealed with sealant.
[0016] Preferably, in step S2, the steel plate is spot-welded to the steel beam and the purlin for fixed connection.
[0017] Preferably, in step S2, after the steel plate is spot-welded to the steel beam and the purlin, it is then sealed with sealant.
[0018] Preferably, in step S3, the first moisture-proof layer includes a self-adhesive waterproof membrane and a waterproof coating applied to the self-adhesive waterproof membrane, wherein the self-adhesive waterproof membrane extends and is laid on the wall with an extension height greater than the thickness of the perlite integrated board.
[0019] Preferably, in step S3, after the self-adhesive waterproof membrane is extended and laid on the wall, a layer of insulation board is laid on the wall.
[0020] Preferably, in step S4, the second moisture-proof layer is extended and laid on the insulation board with the same extension height as the insulation board.
[0021] The beneficial effects of this invention are:
[0022] The waterproofing construction method for steel structure roof walls provided by this invention involves installing connectors between the wall and the steel beams before laying a layer of steel plates on the steel beams and purlins. When laying the steel plates, the connectors can connect with the steel plates, supporting them and preventing them from tipping over. The first moisture-proof layer is then laid on the steel plates. Due to the supporting effect of the steel plates, the first moisture-proof layer is not easily deformed, ensuring the dryness of the roof interior. Perlite integrated panels are laid on top of the first moisture-proof layer. Due to the supporting effect of the steel plates, the perlite integrated panels are not left suspended, preventing the connection between the perlite integrated panels and the wall from sinking or deforming and creating gaps. This results in a tight connection between the steel structure roof and the roof walls, preventing rainwater leakage. Laying a second moisture-proof layer on the perlite integrated panels further improves the waterproofing effect of the roof. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] like Figures 1-3 As shown in the figure, this embodiment provides a method for waterproofing steel structure roof walls. This method includes the following steps:
[0034] Step S1: Install connector 1 between wall 100 and steel beam 200.
[0035] Step S2: Lay a layer of steel plate 2 on the steel beam 200 and purlin 300, and fix the steel plate 2 to the steel beam 200, purlin 300 and connector 1.
[0036] It is understandable that before laying a layer of steel plate 2 on the steel beam 200 and purlin 300, a connector 1 is installed between the wall 100 and the steel beam 200. When the steel plate 2 is laid, the connector 1 can be connected to the steel plate 2 to support the steel plate 2 and prevent the steel plate 2 from overturning.
[0037] Step S3: Lay the first moisture-proof layer 3 on the steel plate 2 and extend the first moisture-proof layer 3 to the wall 100.
[0038] Specifically, such as Figure 2 and Figure 3 As shown, the first moisture-proof layer 3 is laid on the steel plate 2. Due to the supporting effect of the steel plate 2, the first moisture-proof layer 3 is not easily deformed. Furthermore, the first moisture-proof layer 3 can prevent indoor water vapor from penetrating into the roof project. It can prevent water vapor from migrating and penetrating into the interior of the roof project when the indoor temperature is high and the roof temperature is low in winter, ensuring that the interior of the roof project is dry, thereby maintaining the good thermal insulation performance of the roof. Furthermore, extending the first moisture-proof layer 3 to the wall 100 can also protect the interior of the wall project from drying out.
[0039] Step S4: Lay the perlite integrated board 4 on the first moisture-proof layer 3, and then lay the second moisture-proof layer 5 on the perlite integrated board 4.
[0040] Specifically, such as Figure 2 and Figure 3As shown, the integrated perlite board 4 is laid on the first moisture-proof layer 3, with one end of the integrated perlite board 4 tightly bonded to the first moisture-proof layer 3 extending onto the wall 100. Due to the supporting effect of the steel plate 2, the integrated perlite board 4 is not suspended below, and its shape will not deform. Therefore, the connection between the integrated perlite board 4 and the wall 100 will not sink or deform, creating gaps. This ensures a tight connection between the integrated perlite board 4 and the wall 100, preventing rainwater leakage. Furthermore, laying a second moisture-proof layer 5 on the integrated perlite board 4 can further improve the waterproofing effect of the roof. Preferably, in this embodiment, the second waterproof layer is made of waterproof membrane laid and adhered to the integrated perlite board 4, which is convenient to construct, requires no curing after forming, is not affected by temperature, and has minimal environmental pollution.
[0041] Optionally, such as Figure 2 and Figure 3 As shown, in step S1, the connector 1 is an angle iron. The first side of the angle iron is attached to the wall 100, and the second side of the angle iron is welded to the steel beam 200. The angle iron has good support strength and can prevent the perlite integrated plate 4 from sinking and deforming. Furthermore, the first end of the angle iron is sealed with sealant between itself and the wall 100. The sealant has good sealing performance and can play a reliable pressure-resistant sealing role, preventing water from seeping in from the tiny gaps between the first end of the angle iron and the wall 100.
[0042] Optionally, such as Figure 2 and Figure 3 As shown, in step S2, one end of the steel plate 2 is placed on the second side of the angle iron and welded to the first side of the angle iron. In addition, the steel plate 2 is spot-welded to the steel beam 200 and the purlin 300 to fix it in place, thereby firmly fixing the steel plate 2 to prevent it from being misaligned, which in turn causes the perlite integrated plate 4 to shift, causing cracks to occur at the connection between the perlite integrated plate 4 and the roof wall 100. Furthermore, after the welding is completed, the junction of one end of the steel plate 2 and the first side of the angle iron is sealed with sealant to improve the water-proof effect.
[0043] Optionally, in step S3, the first moisture-proof layer 3 includes a self-adhesive waterproof membrane and a waterproof coating applied to the self-adhesive waterproof membrane, providing good airtightness and watertightness, effectively preventing indoor water vapor from penetrating into the perlite integrated board 4. Further, the self-adhesive waterproof membrane extends and is laid on the wall 100 with an extension height greater than the thickness of the perlite integrated board 4, preventing water vapor from seeping into the perlite integrated board 4 from the end abutting against the wall 100.
[0044] Optionally, such as Figure 2 and Figure 3As shown, in step S3, in order to improve the thermal insulation performance of the wall 100, after the self-adhesive waterproof membrane is extended and laid on the wall 100, a layer of insulation board 6 is laid on the wall 100. Furthermore, when laying the second moisture-proof layer, the second moisture-proof layer 5 is extended and laid on the insulation board 6 with the extension height being equal to that of the insulation board 6, so as to protect the insulation board 6 from rainwater erosion and ensure the thermal insulation effect.
[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
