與傳統(tǒng)材料制作的車(chē)棚相比，膜結(jié)構(gòu)車(chē)棚的篷布材質(zhì)是膜結(jié)構(gòu)，而膜材的特點(diǎn)是強(qiáng)度高、耐久性好、防火難燃、自潔性好，不受紫外線影響，使用壽命長(zhǎng)。具有高透光率，透光率為13%,對(duì)熱能反射率73%，熱吸收量很少。同時(shí)，膜結(jié)構(gòu)停車(chē)棚還具備以下優(yōu)點(diǎn)：

Compared with the shed made of traditional materials, the tarpaulin material of the membrane structure shed is membrane structure, and the membrane material is characterized by high strength, good durability, fire resistance, self-cleaning, free from the influence of ultraviolet light, and long service life. It has high light transmittance, 13% light transmittance, 73% heat reflectivity, and little heat absorption. Meanwhile, the membrane structure parking shed also has the following advantages:

采光系數(shù)高照射到屋面的陽(yáng)光以漫射光的形式透射到室內(nèi)。膜結(jié)構(gòu)停車(chē)棚從內(nèi)部看，屋面成為一個(gè)接連的光明面，其強(qiáng)度因屋面與太陽(yáng)的相對(duì)位置而改變。張力膜結(jié)構(gòu)室內(nèi)空司的采光系數(shù)（即室表里表面天然光日照程度之比）一般可高達(dá)10%;

The daylighting coefficient is high. The sunlight shining on the roof is transmitted indoors in the form of diffuse light. From the inside of the membrane structure parking shed, the roof becomes a continuous bright surface, and its strength changes due to the relative position of the roof and the sun. The daylighting coefficient (i.e. the ratio of natural light and sunlight on the surface of the interior and exterior of the room) of the indoor air conditioner with tension membrane structure can generally be as high as 10%;

而在傳統(tǒng)修建中，光輝只能從有限的采光窗進(jìn)入室內(nèi)，其采光系數(shù)不到3%。即便在陰天，膜結(jié)構(gòu)室內(nèi)的光照程度也能夠滿足大多數(shù)活動(dòng)的基礎(chǔ)要求。沒(méi)有眩光由于進(jìn)入膜結(jié)構(gòu)室內(nèi)的透射光和反射光都是漫射光，不太可能出現(xiàn)眩光。但要考慮玻璃采光區(qū)的組織及遮陽(yáng)以避免其直射光形成的眩光。

However, in the traditional building, the brilliance can only enter the room from the limited daylighting windows, and its daylighting coefficient is less than 3%. Even in overcast days, the lighting level in the membrane structure room can meet the basic requirements of most activities. There is no glare. Since the transmitted light and reflected light entering the membrane structure room are diffuse light, glare is unlikely to occur. However, the organization and shading of the glass lighting area shall be considered to avoid the glare caused by its direct light.

膜結(jié)構(gòu)停車(chē)棚在室內(nèi)人們對(duì)白色或米白色膜材會(huì)有很好的顏色感知，由于這兩種顏色表現(xiàn)出對(duì)可見(jiàn)光具備線性光譜透射的特征。透射程度隨透射光波長(zhǎng)的增加而增加，這使得透射光比入射光略溫暖。

In the film structure parking shed, people will have a good color perception of white or off white film materials indoors, because these two colors show the characteristics of linear spectral transmission to visible light. The degree of transmission increases with the increase of the wavelength of the transmitted light, which makes the transmitted light slightly warmer than the incident light.

濟(jì)南停車(chē)棚廠家認(rèn)為透射光譜與纖維及其特性、涂層的厚度以及附加面層有差，生產(chǎn)商應(yīng)給出更多的詳細(xì)信息。相對(duì)于涂覆PVc的聚酯纖維膜材，涂覆PTFE的玻璃纖維膜材的透射光譜。

Jinan parking shed manufacturer thinks that the transmission spectrum is different from the fiber and its characteristics, the thickness of the coating and the additional surface layer, and the manufacturer should give more details. The transmission spectrum of the PTFE coated glass fiber film is higher than that of the PVC coated polyester fiber film.
