Description
Technical field
The utility model relates to a kind of anti-deformation and anti-leakage structure of PC plate lighting roof.
Background technology
PC plate (also claiming sunlight board) is to be the macromolecule engineering plastics that raw material processes with the polycarbonate.Compare with glassy phase, especially be applied on the roofing materials, the most significant advantage of polycarbonate plate is exactly non-friable, strong shock resistance, has overcome the shortcoming of Glass breadks easily, and its possibility of hurting sb.'s feelings of falling is reduced greatly.The polycarbonate plate roofing is compared with glass roofing and is also had following advantage in addition:
(1) design strength of polycarbonate plate is 1.16 times of glass, and this makes the polycarbonate plate roofing have the ability that can bear enough wind loads, snow load and other loads;
(2) because the polycarbonate plate quality is very little, can effectively reduce the quality of support keel and agent structure, reduce the sectional dimension of braced structures, save construction cost;
(3) polycarbonate plate can cold roll forming, and cutting is simple, is more suitable for the roof structure in complex object;
(4) polycarbonate plate has more excellent heat-insulating property than glass, the thermal transmittance of general polycarbonate plate is littler by 4%～25% than glass, and the heat-insulating property of insulation clear polycarbonate plate exceeds 40% of simple glass, under the same conditions, the polycarbonate plate roofing is compared with glass roofing, can save 40% energy consumption;
(5) polycarbonate plate roofing and glass roofing mutually specific energy produce more optical effect.Polycarbonate plate not only has transmission, refraction, the reflecting properties of glass, and has the characteristics of free from glare.
Have above advantage just because of polycarbonate plate, just progressively be applied to the lighting roof system now.But, because polycarbonate plate coefficient of thermal expansion (α=6.75x10 ℃-1) is bigger, be 7 times of simple glass approximately, in use the variation of the plate length that causes owing to variations in temperature is bigger.In addition, the modulus of elasticity of polycarbonate plate also less relatively (E=2.3x10MPa), rigidity is relatively poor, so just make plate in the process of using, occur the situation of " playing drum " easily, thereby have influence on the planeness and the aesthetic property of whole roofing, and the seam between the plate also is easy to generate drawing crack in long-term reciprocal stretching, contraction process, seepage occurs.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the anti-deformation and the anti-leakage structure of the utility model PC plate lighting roof, comprise support keel system 20 and the aluminium alloy joist of establishing thereon 16, aluminium alloy joist 16 is provided with panel unit, panel unit is connected to form by stainless steel gland screw 2 and the secondary frame 4 of aluminium alloys by PC plate 1, the stainless steel gland screw 2 outer O-ring seals 14 that are with stainless steel spacer sleeve 3 and EPDM (ethylene propylene diene rubber) material respectively, the secondary frame 4 of aluminium alloys is provided with the location film 13 of EPDM material.The border of panel unit is buckled with aluminium alloys edge sealing profile 8, be filled with sealing joint strip 6 in the aluminium alloys edge sealing profile 8, sealing joint strip 6 is the turriform sealing joint strip of EPDM material, which is provided with silicone weather resistant glue 7, adjacent panel unit connects by the aluminium alloys pressing plate 5 that is located in the aluminium alloy joist 16, and aluminium alloys pressing plate 5 is fixed on the support keel system 20 by stainless steel bolt 9.Aluminium alloys pressing plate 5 is provided with aluminium alloys profile 12, is filled with foam-filled excellently 10 between the adjacent panel unit aluminium alloys edge sealing profile 8, which is provided with sealing glue-line 11.The both sides of aluminium alloy joist 16 are provided with the location sealing joint strip 15 of EPDM material, are used for location and sealing between PC plate 1 and the aluminium alloy joist 16.Be arranged with the group frame angle sign indicating number 17 of reinforcing and supporting role in the aluminium alloy joist 16.
Shown in Fig. 4,5,6, the inside of the utility model aluminium alloy joist 16 is provided with main rhone 18 and time rhone 18 '.Main rhone 18 arranges that along roof pitch direction F inferior rhone 18 ' all inserts main rhone 18.Main rhone 18 and time rhone 18 ' are fixing by main rhone keeper 19 and time rhone keeper 19 ' respectively.Main rhone 18 and time rhone 18 ' are the aluminium alloys rhone that the cell body degree of depth is 21mm.
When the utility model is installed, at first with the secondary frame group of aluminium alloys frame, again the PC plate is connected by the secondary frame 4 of special stainless steel gland screw 2 and aluminium alloys, at last, buckle aluminium alloys edge sealing profile 8 in the border of panel unit, fill in turriform sealing joint strip 6, stamp silicone weather resistant glue 7, form a panel unit shown in Figure 2.Shown in Fig. 3, Fig. 3-1, PC plate 1 temperature influence by specification 1800 * 1500mm calculates and can get, heat expansion distortion maximum size is+2mm, the shrinkage distortion is-1mm the initial cross-section width D 1=4mm of O-ring seal 14, the initial cross-section width D 2=5mm of sealing joint strip 6 to the maximum, PC plate 1 distortion anteposition is changed to X1, then the position after 1 distortion of PC plate is X2, its maximum scalable distance D=2mm, breadth of section the D2 '=3mm after sealing joint strip 6 distortion.When change in size takes place because of ambient temperature changes in PC plate 1, in the inner size that just can digest these variations of panel unit self, and stretching that can be not reciprocal sealing glue-line 11, thereby can reduce the possibility that seals glue-line 11 drawing cracks greatly.
