Roof lining plate waterproof fixing structure

Abstract

The utility model discloses a waterproof fixing structure for roof lining plates, which is characterized in that a pair of lining plates is arranged on each of two different sides of a fixing bracket, and the upper part of each lining plate is clamped by a buckling cap through an inverted buckling structure, so that the pair of lining plates get close to and are fixed towards the fixing bracket under opposite clamping force to form sealing. A sealing strip used for improving the water tightness of the upper portion of the lining plate is arranged between the buckling cap and the lining plate. By arranging the sealing strips on the buckling caps, rainwater is prevented from penetrating through the buckling caps to spread into splicing gaps of the lining plates, and the overall water tightness of the fixing structure is improved.

Description

Technical Field

[0001] This utility model relates to the field of roofing system panels, and in particular to a waterproof fixing structure for roofing lining panels. Background Technology

[0002] The roofs of large public facilities such as stadiums and high-speed rail stations are mostly constructed using composite lining panel structures. This structure offers the advantage of rapid installation and the ability to achieve various complex architectural designs. However, due to the extensive use of splicing, leaks are very likely to occur at the joints. For example, prior application No. 2025201032925 disclosed an integrated lining panel fixing base and a modular roof structure. Under high-pressure wind loads, rainwater can easily seep into the pressure cap at the connection between the pressure cap and the lining panel, eventually flowing into the roof through the gaps between the lining panels and causing leaks. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a waterproof fixing structure for roof lining boards to solve the problem of leakage at the joints.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A waterproof fixing structure for roof lining panels includes a pair of lining panels on opposite sides of a fixing bracket. The upper part of the lining panels is clamped by a snap-fit ​​cap through an inverted snap structure, so that the pair of lining panels are subjected to opposing holding forces and are fixed towards the fixing bracket to form a seal. A sealing strip is provided between the snap-fit ​​cap and the lining panels to improve the water tightness of the upper part of the lining panels.

[0006] Furthermore, the sealing strip is a first sealing strip, which is enclosed within the fastening cap and located at the overlap between the upper part of the liner and the upper part of the fixing bracket.

[0007] Furthermore, the fastening cap has flanges extending to both sides, and the sealing strip is a second sealing strip, which is placed on the flanges and contacts the upper surface of the liner.

[0008] Furthermore, a support column is provided at the top of the fixed bracket, which pushes the fastening cap upward to further increase the clamping force of the fastening cap on the upper part of the liner.

[0009] Furthermore, the support column and the litigation fastening cap are fastened together by bolts.

[0010] The beneficial effects of this utility model are as follows:

[0011] The waterproof fixing structure for roof lining provided by this utility model improves the overall water tightness of the fixing structure by arranging sealing strips on the snap-fit ​​caps to prevent rainwater from spreading into the gaps between the lining panels through the snap-fit ​​caps.

[0015] Figure 3 This is a schematic diagram of the second implementation of the fixed structure. Detailed Implementation

[0016] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does 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. Therefore, it should not be construed as a limitation of this utility model.

[0017] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features.

[0018] In the specification, when an element is described as being "on," "fixed" to, "connected" to, or "joined" to another element, the element may be directly located on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element present. In the specification, the description of a feature being arranged "adjacent" to another feature may refer to a feature having a portion that overlaps with the adjacent feature or a portion located above or below the adjacent feature.

[0019] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.

[0020] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0021] Figure 1 The display shows the arrangement structure of the roof lining panels. The roofs of large public buildings such as stadiums and train stations are usually made up of a large number of lining panels 1, which are spliced ​​and connected to adjacent lining panels 1 at the fixed structure 2.

[0022] Figure 2 This paper demonstrates a first embodiment of this fixing structure. The fixing structure 2 mainly includes a snap-fit ​​cap 21 clamped onto the upper part 11 of a pair of lining plates and a bracket 23 positioned between the pair of lining plates 1 as a support. Toothed edges 12 are provided on both sides of the upper part 11 of the lining plates, and corresponding buckles 22 are provided on the inner side of the snap-fit ​​cap 21. Therefore, when the toothed edges 12 and the buckles 22 are engaged, the snap-fit ​​cap 21 clamps the upper part 11 of the lining plates and prevents it from coming loose. A pair of first sealing strips 27 are arranged on the inner side of the snap-fit ​​cap 21. The first sealing strips 27 overlap at the joint between the upper part 11 of the lining plates and the upper part 24 of the bracket, preventing rainwater from extending upwards through the buckles 22 and seeping into the roof through the gap between the upper part 11 of the lining plates and the upper part 24 of the bracket. The advantage of this solution is that the waterproof structure is integrated into the inner side of the snap-fit ​​cap 21, resulting in a simple structure.

[0023] Figure 3 A second embodiment of this fixing structure is shown. The fastening cap 21 has outwardly extending flanges 21a on both sides, and a second sealing strip 28 is located below the flanges 21a. The fastening cap 21 is fixed to the upper part 11 of the liner plate, forming a seal on the upper surface 1a of the liner plate 1 to prevent rainwater from entering the inverted buckle 22. A support column 25 is also arranged on the upper part 24 of the bracket to further reinforce the fastening cap 21. The support column 25 lifts the fastening cap 21 upwards, further increasing the downward pressure of the fastening cap 21. Bolts 26 are also added to the top of the fastening cap 21 to connect it to the support column 25, making the entire fixing structure 2 more stable. The advantage of this solution is that the waterproof structure is integrated into the outside of the fastening cap 21, maximizing water tightness, but it requires the support column 25 to ensure the downward pressure of the fastening cap 21.
