[0038] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be described in further detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0039] Please refer to Figures 1 to 5 The utility model discloses a three-element ethylene propylene composite steel plate roof waterproof board, which comprises a plate body 10 and a waterproof layer 103 arranged on the surface of the plate body 10. The side of the plate body 10 facing the waterproof layer 103 is further provided with an adhesive layer. The waterproof layer 103 is integrally vulcanized and formed with the plate body 10.

[0040] It should be noted that the plate body 10 can be a galvanized steel plate. The thickness of the plate body 10 is 0.5mm to 2.0mm. The waterproof layer 103 can be a three-element ethylene propylene rubber material. The thickness of the waterproof layer 103 is 0.5mm to 2.0mm. The adhesive layer can be polyurethane. The plate body 10 and the waterproof layer 103 are supplied to the vulcanization equipment after extrusion. After common vulcanization, the plate body 10 and the waterproof layer 103 form a tightly combined composite plate material. Then, the plate is pressed by a tile press according to the required size and model of the roof.

[0041] Compared with the prior art, the three-element ethylene propylene composite steel plate roof waterproof board provided by the embodiment has the following advantages:

[0042] The adhesive layer is coated between the plate body 10 and the waterproof layer 103. Then, the plate body 10 and the waterproof layer 103 are tightly combined by the vulcanization equipment. This reduces the possibility of edge lifting of the waterproof layer 103, thereby improving the service life of the roof waterproof board.

[0043] In some examples, referring to Figure 1 The plate body 10 has alternating groove portions 101 and protruding portions 102. The bottom of the protruding portion 102 is enclosed to form a trapezoidal support groove 104. A plurality of horizontal support systems 20 and a plurality of vertical support systems 30 are arranged in the support groove 104 along the length direction of the support groove 104.

[0044] The transverse support system 20 comprises two telescopic assemblies and a power member, the telescopic assembly has a telescopic part and a connecting part, the connecting part is detachably fixed with the top wall of the support groove 104, the telescopic part is slidably connected with the connecting part, the telescopic part of one of the telescopic assemblies is used for supporting an inner side wall of the support groove 104, and the power member is used for driving the two telescopic parts to move away from each other until abutting against the side wall of the support groove 104.

[0045] The vertical support system 30 is used for supporting between the roof and the connecting part

[0046] The telescopic part abuts against the side wall of the support groove 104, thereby reducing the possibility that the two sides of the protruding part 102 are deformed when the protruding part 102 is subjected to stress; the vertical support system 30 and the connecting part abut against the top wall of the support groove 104, thereby reducing the possibility that the top of the protruding part 102 collapses downward when the protruding part 102 is subjected to stress. As can be seen, the transverse support system 20 and the vertical support system 30 are arranged to support the protruding part 102, thereby improving the anti-deformation capability of the protruding part 102.

[0047] In some embodiments, referring to Figures 1 to 3 , the telescopic assembly comprises a fixed seat 202 and a one-way screw rod 203, the fixed seat 202 forms the connecting part, the one-way screw rod 203 forms the telescopic part, the one-way screw rod 203 penetrates through the fixed seat 202 and is slidably connected with the fixed seat 202, and the one-way screw rod 203 is connected with a side plate 201 abutting against the side wall of the support groove 104 at one end.

[0048] The power member is used for driving the one-way screw rod 203 to move the side plate 201 away from the fixed seat 202 until the side plate 201 abuts against the inner side wall of the protruding part 102, thereby increasing the area in contact with the side wall of the support groove 104, improving the support capability of the side wall of the support groove 104, and further improving the anti-deformation capability of the protruding part 102.

[0049] The fixed seat 202 is detachably connected with the top wall of the support groove 104, so that the transverse support system 20 and the vertical support system 30 can be repeatedly used; and the spacing between the side plate 201 and the fixed seat 202 is adjustable, so that the transverse support system 20 can be adapted to protruding parts 102 of different widths.

[0050] Figure 2 The structure in the figure is a one-to-one correspondence between the one-way screw rod 203 and the side plate 201, and a plurality of one-way screw rods 203 can be arranged on the same side plate 201 along the extension direction of the support groove 104.

[0051] In some embodiments, referring to Figure 3 , the power member is a threaded sleeve 204, the threaded sleeve 204 is rotationally connected between the two fixed seats 202 around the central axis thereof, the two one-way screw rods 203 are threadedly connected with the threaded sleeve 204 away from the side plate 201 at one end, and the screw threads of the two one-way screw rods 203 are opposite in rotation direction.

[0052] Rotating the threaded sleeve 204 makes the one-way screw 203 slide in the fixed seat 202, so that the two one-way screws 203 drive the two side plates 201 to move away from each other until the side plates 201 abut against the side walls of the support groove 104.

[0053] In some embodiments, referring to Figure 3 , the fixed seat 202 is provided with a through slot 2021 through which the one-way screw 203 passes, and a limiting block 2022 is fixedly arranged on the inner wall of the through slot 2021. The outer wall of the one-way screw 203 is provided with a limiting groove 2031 which is in sliding fit with the limiting block 2022.

[0054] During the sliding of the one-way screw 203 in the fixed seat 202, the limiting block 2022 slides in the limiting groove 2031, and the limiting block 2022 makes the one-way screw 203 move only along the length direction of the one-way screw 203, thereby playing a guiding and limiting role on the one-way screw 203.

[0055] In some embodiments, referring to Figure 3 and Figure 4 , the end of the one-way screw 203 is hingedly connected with the side plate 201.

[0056] Specifically, a torsion spring 2011 is installed at the hinged connection between the one-way screw 203 and the side plate 201.

[0057] The included angle between the one-way screw 203 and the side plate 201 can be adjusted according to the slope of the side wall of the support groove 104, thereby further improving the applicability of the transverse support system 20.

[0058] In some embodiments, referring to Figure 5 , the vertical support system 30 comprises a pad 301, two adjusting blocks 302, a resilient member 303 and a distance adjusting assembly. The two adjusting blocks 302 are oppositely arranged, and the opposite surfaces of the two adjusting blocks 302 are both inclined surfaces 3022 which abut against the bottom of the connecting portion. The resilient member 303 is arranged between the pad 301 and the connecting portion, and has a pre-tightening force which makes the connecting portion abut against the inclined surface 3022. The distance adjusting assembly is used to adjust the distance between the two adjusting blocks 302.

[0059] Specifically, the resilient member 303 can be a spring rod.

[0060] The two adjusting blocks 302 are made close to or far away from each other by the spacing adjusting assembly, so that the contact points of the connecting part with the inclined surface 3022 are at different heights, thereby the spacing between the connecting part and the pad block 301 is different; the higher the contact points of the connecting part with the inclined surface 3022 are, the greater the spacing between the connecting part and the pad block 301 is, so that the total length of the connecting part and the pad block 301 is longer. Therefore, the total length of the connecting part and the pad block 301 can be adjusted, so that it can be adapted to support grooves 104 of different depths.

[0061] In some embodiments, referring to Figure 5 , the top wall of the pad block 301 is provided with an adjusting groove 3011, the bottom of the adjusting block 302 is provided with a protrusion 3021 which is slidingly matched with the adjusting groove 3011, and the spacing adjusting assembly comprises a bidirectional screw 304 which is rotationally connected in the adjusting groove 3011, the threads at both ends of the bidirectional screw 304 are opposite in rotation direction, the bidirectional screw 304 is threadedly connected with the corresponding two protrusions 3021, and the two protrusions 3021 are respectively arranged on the two threads of the bidirectional screw 304.

[0062] The rotation of the bidirectional screw 304 makes the two protrusions 3021 close to or far away from each other, thereby making the two adjusting blocks 302 close to or far away from each other, so that the spacing between the two adjusting blocks 302 is adjusted.

[0063] In some embodiments, referring to Figure 5 , the spacing adjusting assembly further comprises a driving roller 305 which is rotationally connected in the pad block 301 around a central axis thereof, one end of the driving roller 305 is fixedly connected with the bidirectional screw 304, and the other end of the driving roller 305 extends out of the pad block 301.

[0064] Specifically, the end of the driving roller 305 extending out of the pad block 301 is fixedly provided with a hand wheel 3051.

[0065] The rotation of the hand wheel 3051 by the worker makes the driving roller 305 rotate, thereby driving the bidirectional screw 304 to rotate; the space in the adjusting groove 3011 is limited, and the driving is extended to the outside of the pad block 301 by the driving roller 305, so that the worker can drive the bidirectional screw 304 to rotate through the hand wheel 3051.

[0066] In some embodiments, referring to Figure 5 , the connecting part is ball-hinged with a ball 2023, and the inclined surface 3022 is provided with a rolling groove 3023 which is rollingly matched with the ball 2023.

[0067] Specifically, the ball 2023 is ball-hinged at a corner where the connecting part abuts against the inclined surface 3022.

[0068] When the two adjustment blocks 302 move toward or away from each other, the balls 2023 roll in the rolling grooves 3023 , thereby reducing the friction between the connecting portion and the adjustment blocks 302 and improving the smoothness of the movement of the adjustment blocks 302 .

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
