1. The technical principle and scheme design

1. 1 technical principle

photovoltaic panel flexible stent used between two fixed point tensioning prestressed steel strand 【 Stranded wire is made of the number of wire twisted steel, carbon steel surface can be according to the need to increase the zinc coating, zinc alloy, aluminum layer ( 铝壳) , copper plating layer and coating epoxy resin ( 环氧涂层) And so on. 】 Way, the rigid foundation in two fixed point reaction, can achieve 10 ~ 30 m spacing. This kind of design can avoid the disadvantage of high mountain ups and downs, vegetation, only in the right place to set basic point and tensioned prestressed steel strand; At the same time, in the depth of the water deep fishing pond 【 【 Pinyin 】 于唐【 Phonetic 】 One ㄩ ˊ ㄊ ㄤ ˊ 【 Entry 】 Fishing pond ( Fishing pond) 【 Citation explaining 】 Farmed fish pond. 】 Can also be in keeping the water level under the condition of fixed, the foundation of the implementation and flexible stent of the construction.

, in the design of steel strand as component installation fixed bracket, should be considered when calculating weight, under different load combination and wind pressure, snow pressure condition, stress analysis was carried on the Will be the research object is regarded as an isolated object and analyze it by the external force characteristics of the method. 】 。 Different from traditional bracket deformation of rigid requirements strictly limited ( Main girder for L / 250, secondary beam for L / 200 / 1] ) , flexible stent to deformation is not strictly limited, according to actual situation using deflection permissible value L / 30 ~ L / 15, under the condition of the deformation does not affect the mechanical properties of steel strand, as a result, the flexible stent can better adapt to large span plan, can control the total cost at the same time.

1。 Based design

2 flexible support scheme is changing the traditional rigid support scheme of purlin to steel strand, characterized by a steel strand first line method is used to provide strong, components installed under different working condition of bearing allows for a certain deformation (steel strand This paper according to the deflection permissible value L / 30) , so as to realize the large span of 10 ~ 30 m bracket, can meet the needs of different terrain. Because of the existence of steel strand tensioned prestressed pillars will produce larger horizontal tension, lead to base at the bottom of the bending moment is larger, therefore the general design USES the pillars with suspension 【 When you came to the nu river on both sides of the hospitable clan will be served you a bowl of steaming 'suspension' after eat, you'll feel refreshment. 】 Or support plan balance tension of horizontal force, to meet the requirements of the stress of the column bottom resistance to capsizing.

according to the overall design scheme of the flexible support and mechanical characteristics, foundation forms can be used in figure 1, figure 2 two forms.

1) Plan 1: using two base, one is the steel column base, chongqing mainly provide the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Flexible support vertical force of reaction; The other should be equipped with a cable 【 Author is stay-cables west huai published in sina's reading a novel. 。 。 】 Basis, undertake steel wire produced by horizontal force, and take up tension and pull to the right, basic cable belong to the type of balancing.

2) Scheme 2: using two base, one is the steel column base, mainly provide the reaction force of flexible support vertical force; The other requires brace column foundation, take the pull force caused by steel strand, and steel wire on the diagonal brace base downward pressure and thrust to the right. Brace column foundation base area of foundation plan 1 slightly smaller relatively.
