[0026] In the implementation mode of the utility model, the roof is formed into a waterproof roof structure by combining waterproof kits. The waterproof kit includes trough-shaped parts and prefabricated parts. When installed, the trough-shaped parts are spread out horizontally and in parallel, and adjacent trough-shaped parts are connected to each other, and the connection places form wave crests; and the state of the prefabricated parts during installation is a prefabricated trough body with an opening facing downward, which is buckled on the wave crest. The trough-shaped parts can be stamped from metal plates and coated during factory production; the prefabricated parts can also be stamped metal plates and coated, or the prefabricated parts can be directly injection molded from thermoplastic polyolefin elastomer (TPO). Therefore, when the installation is completed at the construction site, a roof structure with a waterproof membrane on the entire upper surface is formed. This method does not require on-site coating operations, avoiding problems such as low efficiency caused by on-site coating. The specific contents of the implementation mode of the utility model are explained below in conjunction with the accompanying drawings.

[0027] In this embodiment, the grooved parts and prefabricated parts in the waterproof kit can be processed and formed in the factory first. Figure 2 and Figure 3 As shown, Figure 2 is a schematic diagram of a plate used for forming a groove-shaped member in an embodiment of the utility model, Figure 3 It is a cross-sectional schematic diagram of the channel-shaped member in the embodiment of the utility model. Figure 2 The cross section of the channel sheet 20 is also shown, which is presented as a line segment AJ. The basis of the channel sheet 20 is a metal plate, usually a stainless steel plate, and a waterproof membrane 201 is provided on the DG section of the channel sheet 20. Figure 3 The channel-shaped member 2 shown, see Figure 3 , is the cross-sectional state of the grooved member 2, and the cross-sectional direction is Figure 1 The AA' section direction is the same.

[0028] For the sake of clarity, the parts arranged in the left and right directions are represented by Figure 3 Taking the perspective as an example, the part on the left is named "first" and the part on the right is named "second". Figure 4 , Figure 5 So too. Figure 3 In the embodiment, after stamping, the AC segment forms the first connecting member, the AB segment is the first arc loop portion, the BC segment is the first extension portion, the CD segment has no waterproof film, the CE segment is the first groove wall, the EF segment is the groove bottom, the FH segment is the second groove wall, the GH segment has no waterproof film, the HJ segment forms the second connecting member, the HI segment is the second extension portion, and the IJ segment is the second arc loop portion. Figure 3 For the grooved member 2, the height AJ of the segment can be 600 mm, and the height A of the CD and GH segments can be 10 mm.

[0029] from Figure 3 It can be seen from the figure that the arc loops in the first connecting member and the second connecting member are of different sizes, so that the first connecting member of one slot-shaped member can be put inside and outside the second connecting member of another slot-shaped member to form a connection between the two slot-shaped members. Because each slot-shaped member has a first connecting member and a second connecting member, in the extension direction of the plurality of slot-shaped members (by Figure 3 In the parallel arrangement of the viewing angle (far-near direction), multiple slot-shaped members can be arranged in the left and right directions (by Figure 3 Perspective, see also Figure 5 ) are connected into one piece and can be used to cover the roof.

[0030] The existing technology adopts the method of film pasting on the construction site. Since the board has a bend after being formed, such as Figure 3 At the points E and F in the figure (the points E and F are actually an edge extending in the far-near direction, i.e., a line, and the other letter marks in the following text are also lines, and the expression "point" is still used for convenience of description in conjunction with the drawings), as well as the points L, M, N, O, P, and Q mentioned below, the waterproof membrane at the bend may not fit closely with the metal plate, i.e., forming a "hollow". In this embodiment, the plate with a waterproof membrane is used to make the groove-shaped part, which can form a good fit between the waterproof membrane and the metal plate, and there is no need to apply the membrane on site, which helps to improve the construction efficiency.

[0031] Figure 4It is a schematic diagram of the cross section of the preform in the embodiment of the utility model. The preform 3 is formed into multiple sections, wherein the KL section is the first bottom surface, the LM section is the first side wall, the MP section is the top surface, the MN section is the first shoulder, the NO section is formed with a top ring 30, the OP section is the second shoulder, the PQ section is the second side wall, and the QR section is the second bottom surface. It can be seen that the LQ section forms a preform groove body 31 opening downward, and when the two groove-shaped parts are connected, the shape of the wave crest formed at the connection matches the shape of the preform groove body 31, so that the preform groove body 31 can cover the wave crest to form protection. The following is combined with Figure 5 Please explain.

[0032] Figure 5 Schematic diagram of the state where the prefabricated part in the embodiment of the utility model covers the wave crest. Figure 5 As shown, the first grooved member 21 on the left and the second grooved member 22 on the right can be connected via the second connecting member 212 of the first grooved member 21 and the first connecting member 221 of the second grooved member 22. After the connection, a wave crest is formed, and the wave crest position corresponds to Figure 5 The preform 3 covers the wave crest, and the top ring 30 is sleeved on the first connecting member 221 and the second connecting member 212, so that Figure 5 The vertical and horizontal directions of the viewing angle form a constraint on the relative movement between the top ring 30 and the first connecting member 221 and the second connecting member 212, and the two side walls of the prefabricated member 3 are in contact with the two groove walls of the groove-shaped member, so the AD section and the GJ section of the groove-shaped member that are not covered with a waterproof membrane (see Figure 3 ) formed a good protection.

[0033] from Figure 5 It can be seen that the part of the trough with the waterproof membrane overlaps with the part of the prefabricated part with a large width, so that even if the waterproof membrane shrinks over time, the metal plate underneath will not be exposed; and the trough wall of the trough does not need to be fully coated, and the accuracy of the coating height is low. It only needs to be covered by the prefabricated part. This can reduce the amount of waterproof membrane and facilitate processing. If the bonding strength between the trough and the prefabricated part needs to be further strengthened, the two can be welded. The weld formed by welding can be parallel to the extension direction of the trough and located at Figure 5 The welding is performed within the width (horizontally in the figure) of the KL section and the QR section, that is, between the bottom of the trough and the first bottom surface and the second bottom surface of the prefabricated part. It can be seen that even if there are some cold welds, the trough and the prefabricated part can still be closely fitted, and the waterproofing will not fail.

[0034] By splicing the grooved parts, it is also possible to conveniently arrange a support under the crest to improve the crest strength, so that other structures, such as photovoltaic modules, can be arranged on the crest. Figure 5 , Figure 6 ,in Figure 6 yes Figure 5 In the partial enlarged view of the utility model, the support part 41 of the fixing seat 4 can be connected to the purlin 5 of the roof body with the first screw 61 and the second screw 62, and then the support rod 42 of the fixing seat 4 is connected to the support part 41 with the screw assembly 43, and then the above-mentioned groove-shaped member is placed above the roof and the wave crest is supported by the support part 41. At this time, the upper end of the support rod 42 enters the top ring part 30 to form a limit for the top ring part 30 to swing left and right according to the viewing angle in the figure. This method is more helpful to resist the influence of wind on the photovoltaic panel when the photovoltaic module is set on the top ring part 30.

[0035] Figure 7 It is a schematic diagram of a specific structure of the support part 41 and the support rod 42 in the embodiment of the utility model. Figure 5 and Figure 6 This structure is adopted. Figure 7 As shown, the support portion 41 includes a first section 71, a second section 72, a third section 73, a fourth section 74, a fifth section 75, a sixth section 76, a seventh section 77, and an eighth section 78 which are connected in sequence. The support rod 42 includes a straight rod portion 421 and a curved portion 422. The first section 71 and the eighth section 78 of the support portion 41 are connected to the first screw 61 and the second screw 62 respectively; the second section 72, the fifth section 75, and the seventh section 77 extend longitudinally, wherein the fifth section 75 is connected to the straight rod portion 421 of the support rod 42 by the screw assembly 43; the third section 73 and the fourth section 74 are in contact with the lower side of the wave crest, playing the role of supporting the wave crest upward. The curved portion 422 extends into the top ring portion 30, and is sleeved together with the first connecting member 221 and the second connecting member 212, thereby enhancing the stability of the top ring portion 30.

[0036] In addition, the photovoltaic module is usually fixed to the crest with a clamp. For the roof structure of this embodiment, the photovoltaic module is clamped on the top ring part 30. The clamp usually causes damage to the waterproof membrane, but in this embodiment, even if the waterproof membrane on the top ring part 30 is damaged, it will not cause waterproof failure in other parts. Figure 5 When the photovoltaic module (not shown in the figure) is clamped on the top ring 30, the waterproof membranes at points N and O may be damaged, but the waterproofing of sections KN and OR is not affected. Preferably, when the preform is stamped, the height of point N can be slightly higher than that of point M, and the height of point O can be slightly higher than that of point P, so as to avoid water accumulation at points N and O. Figure 4 or Figure 5 It can also be seen that the lateral (horizontal direction in the figure) distance from point N to point O is smaller than the width of the top ring portion 30 , so that point N and point O can be shielded by the top ring portion 30 when it is raining.

[0037] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
