[0005] The bending portion of the edge closing plate is inclined downward.
[0006] The utility model discloses drip hole is provided at the bending portion of edge closing plate.
[0007] The utility model discloses that sealing glue is filled and sealed at the joint of water plate and sandwich panel.
[0008] The utility model discloses that TPO waterproofing material is covered at the joint of water plate and sandwich panel.
[0009] The utility model discloses sealing glue is filled and sealed at the joint of edge closing plate and the window frame of high window.
[0010] The utility model discloses TPO waterproofing material is covered at the joint of edge closing plate and the window frame of high window.
[0011] Compared with prior art, the utility model has the following advantages and effects:
[0012] 1. The expansion plant room solves the waterproof problem of the sandwich panel wall surface, and ensures the safe production operation of the plant room.
[0013] 2. The structure is reasonable in design, simple in construction, and reduces the construction cost.
[0014] 3. The waterproof measure further improves the heat preservation performance of the wall surface, and reduces the energy consumption. BRIEF DESCRIPTION OF DRAWINGS
[0015] Figure 1 It is a plan structure schematic view of the expansion plant room of the embodiment of the present application.
[0016] Figure 2 It is a structure schematic view of the embodiment of the present application. DETAILED DESCRIPTION
[0017] The present application will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are the explanation of the present application, and the present application is not limited to the following embodiments.
[0018] The embodiment of the present application is applied to Figure 1 the expansion plant room as shown, which comprises a high wall body 11, a low wall body 12, an edge collecting support 4, an edge collecting plate 5, a water collecting plate 8 and rock wool 10.
[0019] A high window 1 is arranged at the high wall body 11, and a sandwich panel 2 is arranged on the surface of the high wall body 11. A low window 3 is arranged at the low wall body 12.
[0020] The edge collecting support 4 is fixed on the bottom of the sandwich panel 2 by rivets. The upper part of the edge collecting plate 5 is fixed on the edge collecting support 4 by rivets, the lower part is bent inward and then extends into the upper part of the window frame of the high window 1 from the bottom of the sandwich panel 2, and is fixed on the window beam of the high wall body 11 by rivets. The bent part of the edge collecting plate 5 is inclined downward, and a water dripping hole 6 is arranged at the bent part. The joint between the edge collecting plate 5 and the window frame of the high window 1 is filled and sealed by sealing glue 7, and the joint is covered by TPO waterproof coiled material, so as to improve the overall waterproof performance of the wall surface. The edge collecting plate 5 wraps the bottom area of the sandwich panel 2, and forms a waterproof effect. If rainwater enters the edge collecting plate 5 by mistake, the rainwater can also flow out from the water dripping hole 6.
[0021] The deformation joint 9 is arranged between the high wall body 11 and the low wall body 12, the water collecting plate 8 is arranged above the deformation joint 9, the upper part of the water collecting plate 8 is fixed on the edge collecting plate 5 by rivets, the lower part is fixed on the window beam of the low wall body 12 by rivets, and the middle part of the water collecting plate 8 is inclined downward by 5°, so as to facilitate the downward flow of rainwater. The water collecting plate 8 prevents rainwater from penetrating from the deformation joint of the new and old plant rooms. The joint between the water collecting plate 8 and the sandwich panel 2 is filled and sealed by sealing glue 7, and the joint is covered by TPO waterproof coiled material.
[0022] The rock wool 10 is fixed in the lower part of the deformation joint 9 to block and improve the heat preservation performance of the whole plant house and reduce energy consumption.
[0023] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different, the above described in the specification is only an example of the structure of the utility model. Any equivalent changes or simple changes made according to the structure, features and principles described in the utility model patent concept are included in the protection scope of the utility model patent. The skilled in the art of the utility model can make various modifications or supplements or adopt similar ways to replace the specific embodiments described, as long as it does not deviate from the structure of the utility model or beyond the scope defined in the claims, which shall belong to the protection scope of the utility model.
