Abstract

The utility model provides a low greenhouse framework structure with high strength. The low greenhouse framework structure consists of a foundation, a ring beam and a top beam. The ring beam is arranged on the upper end face of the foundation; the top beam is arranged at the upper part of the ring beam; and the top beam consists of a plurality of regularly hexagonal primary truss units. The utility model provides the low greenhouse framework structure with the high strength by selecting an optimal parameter range of the foundation, the ring beam and the top beam. The low greenhouse framework structure can resist larger wind load and pressure load on the premise of not increasing a greenhouse construction cost. Particularly, structural parameters of the top beam come from shape outline parameters of a Brazilian turtle back and shape parameters of textures on the turtle back. Shown by the experiment, the turtle-back-shaped greenhouse framework is the low greenhouse framework structure with the high strength, so that not only can the investment cost be reduced, but also the service life is prolonged.

Description

A kind of have a high-intensity short Keelof green house structure

Technical field

The utility model relates to a kind of Keelof green house structure, and a kind of specifically have a high-intensity short Keelof green house structure.

Background technology

At present, based on energy-conservation and environmental protection requirement, the short greenhouse of increasing employing, the greenhouse of some usefulness of growing seedlings.Present low dwarf forms greenhouse also is to reequip according to the structure in common greenhouse, and anti-pressure ability is limited with stability, and the incident that short greenhouse collapses under pressure when snow load, wind carry greatly happens occasionally.In theory, there is a great difference in the structure feature in short greenhouse and common greenhouse, can not copy mechanically and apply indiscriminately the structure in common greenhouse, must be able to be fit to improve the greenhouse structure of short greenhouse compression strength.

The utility model content

The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of high-intensity short Keelof green house structure that has is provided, and under the prerequisite that does not increase greenhouse construction cost, can resist bigger wind load and pressure loading, and greenhouse intensity improves greatly.

The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of have a high-intensity short Keelof green house structure, by ground, collar tie beam and back timber; The section configuration of described ground is an isosceles trapezoid, and the height of ground is at 40-100 ㎝, and the ground bottom width is 2 ~ 4 times of top width; The top of ground is lower than ground 15 ~ 20cm, and the width at the top of ground is at 15-30 ㎝, and described collar tie beam is arranged on the upper surface of ground; The width at the height of collar tie beam and width and ground top equates, surrounds the rectangle of a rounding by collar tie beam, and rectangle length is 4:3 with the ratio of width; Chamfer radius is the half the of width, and back timber is arranged on the top of collar tie beam, spherical in shape of the outline of back timber; Apogee distance ground, back timber center is 2.5-3 meters, and from the smooth collar tie beam upper surface that extends to of peak, back timber is made up of a plurality of regular hexagon main couple unit that are shaped as; Described main couple unit is fixedly connected by angle steel and is the regular hexagon structure, and the angle steel interior angle on each limit is oppositely arranged.

The beneficial effect of the utility model is: the utility model is through selecting the optimal parameter scope of ground, collar tie beam and back timber; A kind of high-intensity short Keelof green house structure that has is provided, and this structure can be resisted bigger wind load and pressure loading under the prerequisite that is not increasing greenhouse construction cost.Especially the structural parameters of back timber come from the form parameter of decorative pattern on shape profile parameters and the curvature of the spinal column of the Brazilian tortoise curvature of the spinal column.Experiment showed, that the greenhouse framework of this imitative curvature of the spinal column type is a kind of high-intensity short greenhouse structure, not only reduces investment cost under the situation of equal materials, and also obtain service life prolonging.

Embodiment

As shown in the figure, a kind of have a high-intensity short Keelof green house structure, by ground 2, collar tie beam 3 and back timber 4; The section configuration of described ground 1 is an isosceles trapezoid, and the height of ground is at 40-100 ㎝, and the ground bottom width is 2 ~ 4 times of top width; Best the top of ground is lower than ground 15 ~ 20cm for the ground bottom width is 2 times of top width, and the width at the top of ground is at 15-30 ㎝; Described collar tie beam 3 is arranged on the upper surface of ground, and the width at the top of the height of collar tie beam and width and ground equates, is surrounded the rectangle of a rounding by collar tie beam; Rectangle length is about 4:3 with the ratio of width, and chamfer radius is the half the of width, and back timber 4 is arranged on the top of collar tie beam; Spherical in shape of the outline of back timber 4, apogee distance ground, back timber center is 2.5-3 meters, from the smooth collar tie beam upper surface that extends to of peak; Back timber 4 is made up of a plurality of regular hexagon main couple unit 401 that are shaped as, and described main couple unit 401 is fixedly connected by angle steel and is the regular hexagon structure, and the angle steel interior angle on each limit is oppositely arranged; Wherein the length of main couple unit 401 length of sides is 30-100 ㎝, and below the preferred version: truss is with angle steel weldering system, and the truss length of side is that the select specification of 30cm when following is 30 * 30 * 3 angle steel; When the truss length of side is 30-60; Selecting specification for use is 30 * 30 * 4 angle steel, and selecting specification when the truss length of side is 60-100cm for use is 40 * 40 * 4 angle steel, and the truss length of side should not surpass 100cm;

The construction method of this Keelof green house structure may further comprise the steps:

Step 1, at first; Confirm that according to the land area in the greenhouse area that is surrounded by collar tie beam is big or small; The shape specification that collar tie beam surrounds is following: surround the rectangle of a rounding by collar tie beam, rectangle length is 4:3 with the ratio of width, and chamfer radius is the half the of width;

Step 2, lay the foundations according to the shape of collar tie beam; The specification of ground is following: the section configuration of ground is an isosceles trapezoid; The height of ground is at 40-100 ㎝, and the ground bottom width is 2 ~ 4 times of top width, and the top of ground is lower than ground 15 ~ 20cm; The width at the top of ground is at 15-30 ㎝, and it is subsequent use that ground is accomplished fluently the back;
