Abstract

The utility model relates to a concrete greenhouse framework without post, comprising an arch frame, a fixed seat and a stable base seat. The arch frame is an L-shaped structure, both ends of the arch frame are separately connected with the fixed seat, and the fixed seat is installed on the stable base seat. Because the utility model adopts a reinforced concrete structure with large span, the utility model substitutes for traditional upright post type greenhouses, and effective using area is increased. The utility model has the advantages of simple structure, easy manufacturing, low cost, large effective using area in greenhouses, good lighting property, good tightness property, stable temperature in greenhouses and easy adjustment.

Description

No column concrete big-canopy framework

The utility model belongs to the green house of vegetables field of stents, specifically is a kind of no column concrete big-canopy framework.

The green house of vegetables planting vegetable, fresh fruit is not subjected to seasonal effect and its investment little because of it, instant effect, be convenient to management, and extensively be used more widely, at present most widely used is the column plastic cover greenhouse, this kind booth is easy to build, but because of tens of to hundreds of of column palpuses, cause the interior daylighting of canopy relatively poor, place the plastic covering on the column need bore a hole fixing, also cause the booth sealing relatively poor, temperature of shed is difficult to control, instability, for this reason, people are actively carrying out new design and old canopy are being transformed, so that canopy good seal, interior temperature is stable, daylighting is beneficial to the growth of plant well, and disclosed 92222269 as Chinese patent, heliogreenhouse tiltedly draws supporting construction, it mainly is to have adopted a pole, be arranged with somely to suspension cable on it, with the main beam tension of slinging, arc skeleton at interval has been connected and fixed on the main beam, arc skeleton the North is built on the wall, on the card concrete foundation of the south, the pole upper end is provided with a pair of stable drag-line and the earth is taken root, and the main beam two ends are stuck on the thing headwall, it is bigger that this structure has span, the advantage that indoor effective area is big, but still there has been complex structure in it, and sealing is relatively poor in the canopy, manufacturing cost is higher, and inconvenient defective is installed.

It is a kind of simple in structure that the purpose of this utility model is to provide, good airproof performance in the canopy, and low cost of manufacture, easy for installation, usable floor area is big in the canopy, the no column concrete big-canopy framework that daylighting is good.

The utility model is achieved through the following technical solutions:

A kind of no column concrete big-canopy framework comprises bow member, holder skin stabilizing base, and bow member is L shaped arc structure, bow member two seat that is connected and fixed respectively, and holder is installed on the stabilizing base.

Bow member one end becomes 70～85 ° of angles downwards, and the other end becomes 105～140 ° of angles.Stabilizing base is a heat-preserving wall, and stabilizing base is a earth, and holder is the square cubic piece, a side has the groove identical with the bow member end face in the top, the holder of bow member one end is installed on the stabilization wall, and the other end is placed in big ground and connects with the earth, is used by common permutation and combination more than 2 groups.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1, the utility model structural representation.

In use, be placed in holder 2 symmetry successively in pre-fixed heat-preserving wall 1 and the earth also fastening, then bow member 3 smoother end cards are placed on the holder 2 that places heat-preserving wall 1, other end card is placed on and places on the intratelluric holder 4, again plastic sheeting being covered bow member 3 tightens, when bow member 3 spans are big, can be at 3 horizontal fastening several drag-lines of bow member, and fastening drag-line is installed on the bow member 3 at two ends firmly is linked together with stabilising arrangement, the holder 2 at these bow member 3 two ends also can all be placed on the body of wall or all be fixedly placed in the earth and fix.

The utlity model has following advantage:

1, simple in structure, be easy to processing, low cost of manufacture.

2, effectively usable floor area is big in the canopy, and lighting performance is good.

3, good airproof performance, temperature of shed is stable, is easy to regulate.
