Abstract
Description
Technical Field
[0001] This utility model relates to the field of building waterproofing boards, and in particular to an adjustable, quick-assembly dot matrix waterproofing board. Background Technology
[0002] Prefabricated composite waterproof and thermal insulation roofing panels are a highly integrated new type of building roofing system. Through factory prefabrication, high-strength metal panels (such as aluminized zinc plates), high-efficiency thermal insulation core materials (rock wool / PUR / PIR), vapor barrier layers, and special fixing components are integrated into standardized panels to form an overall protective layer with waterproof, thermal insulation, wind uplift resistance, fireproof, and vapor barrier functions. This completely eliminates the risks of cold bridging and leakage caused by traditional layered construction. It is especially suitable for large-span roofing projects such as industrial plants and commercial buildings, which can shorten the construction period by more than 50% and significantly improve the durability of the roof.
[0003] The applicant discovered through a search that a Chinese patent, "Prefabricated Composite Waterproof and Thermal Insulation Board for Roofs," with publication number "CN220848363U," discloses a technology that improves the overall layered structure by replacing it with a composite board structure. This enables prefabricated construction of roofing projects, increasing production efficiency. Simultaneously, the composite board structure effectively protects the waterproof layer, preventing damage during construction and ensuring its quality, thus guaranteeing the roof's waterproof function. Furthermore, the presence of waterproof layers both above and below the insulation layer effectively prevents water intrusion, optimizing the roof's thermal insulation performance.
[0004] The above-mentioned device can ensure that the insulation layer is not eroded by rainwater and ensure the quality of the waterproof layer through the setting of a series of structures. However, in actual application, the above-mentioned device requires multiple connectors (such as bolts and screws) to complete the splicing of the panels. It has problems such as inconvenience in disassembly and assembly and inability to adjust the roof size, so the actual use effect is limited. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0022] like Figures 1 to 5 As shown, an adjustable quick-assembly dot matrix waterproofing membrane according to the first aspect of this utility model includes two horizontal beams 4 and two vertical beams 5. The inner walls of the two horizontal beams 4 are respectively fixedly connected to the surfaces of the two vertical beams 5. The top surfaces of the two horizontal beams 4 and the two vertical beams 5 are jointly fixedly connected to two waterproofing membrane bodies 1. The opposite sides of the waterproofing membrane bodies 1 are jointly provided with splicing components 2. The waterproofing membrane body 1 includes a profiled steel sheet 105. A vapor barrier layer 104 is fixedly connected to the top surface of the profiled steel sheet 105. A fireproof layer 103 is fixedly connected to the top surface of the vapor barrier layer 104. A waterproof membrane 102 is fixedly connected to the top surface of the fireproof layer 103. A metal roofing panel 101 is fixedly connected to the top surface of the waterproof membrane 102.
[0023] The technical effects achieved by the above embodiments are as follows: by setting up the waterproof membrane 102, fireproof layer 103, vapor barrier layer 104, metal roof panel 101, and profiled steel sheet 105 in a synergistic effect, the waterproof membrane body 1 achieves the integration of waterproof, heat insulation, fireproof, sound insulation and tensile strength performance; at the same time, the splicing components 2 set on the waterproof membrane body 1 enable it to flexibly adjust the splicing range according to the roof size, so as to achieve fast and stable installation. Example 2
[0024] like Figure 1 and Figure 2As shown, an adjustable quick-assembly dot matrix waterproof membrane includes all the contents of Embodiment 1. Furthermore, the splicing assembly 2 includes a mounting plate 202, one side of which is fixedly connected to one side of one of the waterproof membrane bodies 1. An insert plate 208 is fixedly connected to one side of the mounting plate 202. The splicing assembly 2 also includes a sealing layer 203, one side of which is fixedly connected to one side of the surface of the mounting plate 202. The splicing assembly 2 also includes a fixing shell 201, one side of which has a slot 207. The shape and size of the slot 207 match that of the insert plate 208. The splicing component 2 also includes two sets of fixing grooves 209, with two fixing grooves in each set.
