A kind of imitative freshwater mussel short greenhouse skeleton structure, comprise the greenhouse door, ventilation fan, spandrel girder, collar tie beam and column, annular is fanned in being shaped as that described collar tie beam surrounds, evenly be provided with vertical column on the small arc-shaped of collar tie beam, the top correspondence of collar tie beam small arc-shaped is provided with circular arc type and puts the beams in place, circular arc type is put the beams in place and is connected with the column top, between outermost two columns the greenhouse door is installed on the collar tie beam small arc-shaped, the collar tie beam small arc-shaped, the top of space sealing that forms between circular arc upper beam and the greenhouse door, the crown center of this sealing is equipped with ventilation fan, described spandrel girder is two sections Curved beams that the circular arc smooth excessiveness connects and composes, and the radius ratio that consists of two sections circular arcs of spandrel girder is 8:1, the large radius arc section of spandrel girder is fixedly connected with collar tie beam, small-radius arc section and circular arc are put the beams in place and are fixedly connected with, and the peak of spandrel girder to the ratio of the vertical distance on plane, collar tie beam place and column height is 14:9.
The beneficial effects of the utility model are:
(1) the utility model is by selecting the optimal parameter scope of ground, collar tie beam and spandrel girder, the short greenhouse of a kind of imitative freshwater mussel pressure resistant type framework is provided, this structure the prerequisite that does not increase the Greenhouse Construction cost snow can resist larger wind load and pressure loading;
(2) the inside and outside both sides of the ventilation fan of short greenhouse of the present utility model framework are all the opening that amplifies gradually, form Venturi effect, and generally ventilation fan can naturally rotate and ventilate;
(3) the utility model dispenses the rear wall in general greenhouse, has reduced the greenhouse cost, utilizes film to replace original rear wall, can make better heat preservation;
(4) configuration parameters of the present utility model comes from profile parameters and the form parameter of freshwater mussel shell, experiment shows, in the situation of equal materials, should imitative freshwater mussel type greenhouse framework be a kind of high-intensity short greenhouse structure, not only reduce investment cost, and also obtain application life prolonging.

The specific embodiment
Below in conjunction with specific embodiment the utility model is further elaborated.
As shown in the figure, a kind of imitative freshwater mussel short greenhouse skeleton structure, comprise greenhouse door 1, ventilation fan 2, spandrel girder 3, collar tie beam 4 and column 5, annular is fanned in being shaped as that described collar tie beam 4 surrounds, evenly be provided with vertical column 5 on the small arc-shaped of collar tie beam 4, the top correspondence of collar tie beam 4 small arc-shapeds is provided with circular arc type and puts the beams in place, circular arc type is put the beams in place and is connected with column 5 tops, between outermost two columns 5 greenhouse door 1 is installed on collar tie beam 4 small arc-shapeds, collar tie beam 4 small arc-shapeds, the top of space sealing that forms between circular arc upper beam and the greenhouse door 1, the crown center of this sealing is equipped with ventilation fan 2, described spandrel girder 3 is two sections Curved beams that the circular arc smooth excessiveness connects and composes, and the radius ratio that consists of two sections circular arcs of spandrel girder 3 is 8:1, the large radius arc section of spandrel girder 3 is fixedly connected with collar tie beam 4, small-radius arc section and circular arc are put the beams in place and are fixedly connected with, and the peak of spandrel girder 3 to the ratio of the vertical distance on plane, collar tie beam 4 place and column height is 14:9.
A kind of job practices of imitative freshwater mussel short greenhouse skeleton structure may further comprise the steps:
(1) according to the definite size that is surrounded by collar tie beam of the land area in the greenhouse, annular is fanned in being shaped as that collar tie beam surrounds, and the central angle of fan ring is 156 °, and fanning and encircling internal diameter is 1000mm, and external diameter is 11000mm;
(2) lay the foundations according to the shape of collar tie beam, the specification of ground is as follows: the section configuration of ground is isosceles trapezoid, and the top width of ground is 320mm, bottom width is 2 times of top width, highly also be 2 times of top width, the top of ground is lower than ground 50 ~ 100mm, and ground is accomplished fluently rear for subsequent use;
