Abstract

A roof structure for greenhouses, which, through having a simple arrangement for improving lighting, is capable of retaining the same strength as in the conventional roof structure for greenhouses. A plurality of rafter members in the form of metal pipes of circular cross section formed in arch shape with a pipe diameter of about 30 mm to about 50 mm, are arranged in the direction of the roof ridge at intervals (P) of about 0.5m to about 1.5m. This makes it possible to simplify the construction of the aggregate constituting the roof while retaining a predetermined strength. That is, simply joining the rafter members by ridge pieces provides a sufficient strength to withstand vertical and horizontal loads applied to the roof; therefore, purlin members can be dispensed with. Further, since the construction of the housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.

Description

technical field

[0001] The present invention relates to the roof structure of a greenhouse, and more specifically, to the structure of aggregates constituting the roof of a greenhouse, and a technique for laying a covering material suitable for the structure of the aggregates. technical background

[0002] In the past, as the roof structure of a greenhouse, as shown in FIG. 4, the following structure has been known, that is, a gassho material 100 with a roof forming a gable (gassing palm shape); a ridge arranged along a girder at the top of the roof The wood 110; the purlin material 120 fixed on the gassho material 100 parallel to the ridge 110; the skylight 130 that opens and closes with the ridge 110 as the center of rotation. In addition, a structure in which a rafter material is further provided on the purlin material 120 is also known.

[0003] In addition, JP-A-2002-291348 discloses a simple aggregate structure capable of maintaining the structural strength of a green...
