Description

Technical Field

[0001] It relates to a horticultural house.

Background Art

[0002] In a multi-span horticultural house, due to the high cost of the facilities, cost reduction has become more necessary than ever. However, it is required to reduce costs without reducing the strength. Among them, in order to increase the strength of the gable surface, when constructing continuous gable columns and gable intermediate columns from the foundation to the roof, the strength was increased by increasing the size and number of members including the gable columns and gable intermediate columns. In addition, in the gable part, members for cultivation such as attracting beams and attracting beam bays are often installed, which are included in the cost.

[0003] The skeletal structure of the multi-span agricultural greenhouse described in Patent Document 1 has a truss beam installed between columns in the frontage direction, and a clapboard member that forms a gable shape at the top above it. It has a structure that supports the load from above applied to the clapboard members of the two roof surfaces installed on the truss beam, but it is not a structure that receives the force from the gable surface parallel to the ground.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the construction of multi-story greenhouses for horticulture, the gable end structure has traditionally been designed to withstand wind pressure from the gable end. This was done by using continuous gable and intermediate posts from the foundation to the roof, without intermediate reinforcement, and increasing strength by enlarging or increasing the number of gable and intermediate posts. This was simple and easy to understand. However, reducing the construction cost of the gable end section of the greenhouse requires methods other than those described above. Furthermore, the gable end section often includes necessary components for cultivation, such as support beams and support beams, which are installed at regular intervals to serve as pathways, and these components contribute to the construction cost. [Means for solving the problem]

[0006] This invention provides a gable truss beam structure for a multi-story greenhouse. The outer chord of the gable truss beam is installed horizontally to the gable column, adjacent to the gable column, below the valley section of the gable end, relative to the entire width of the gable end. An inner chord is installed horizontally and parallel to the outer chord. Lattice is evenly placed on both sides, from the center of the ridge to the valley side and the outer side, to form one or more continuous triangles. This structure allows the wind pressure on the gable column to be received even in the middle of the gable column, thereby increasing the strength of the gable end without increasing the size or number of gable columns or intermediate columns. Furthermore, if the position of the gable truss beam relative to the gable end is set at the same height as the width of the passageway or the height of the support beam, it will perform the same function as a support beam. In terms of strength, it is a gable truss beam structure, which is stronger than a support beam. [Effects of the Invention]

[0007] As mentioned above, by constructing a truss beam structure horizontally and parallel to the gable columns across the entire width of the valley at the bottom of the gable face (hereinafter referred to as the "gable face truss beam"), the wind pressure on the gable columns at the gable face is also received in the middle of the gable columns, and this force is received by the entire house, connected in the direction of the gable through the girder beams to which the gable face truss beam is attached, to the valley columns, side columns, girders, and column braces. This means that the force that the gable columns previously received at two points, top and bottom, can now be received at three points, top, middle and bottom, so the load on the gable columns is halved, making it possible to use smaller diameter gable columns or reduce their number. Furthermore, by making the width of the gable face truss beam the width of the passageway and the height the height of the support beam, it can be used as a support beam as well, and it also has the effect of being used as a support beam against wind pressure from the diagonal direction of the gable face, and by using it for both purposes, the number of support beams and support beam supports can be reduced, further reducing costs. [Brief explanation of the drawing]

[0008] [Figure 1] This is a diagram of a multi-unit house with gable end truss beams according to the present invention. [Figure 2] This is a diagram of a multi-story greenhouse with support beams and support joists added to a conventional greenhouse structure. [Modes for carrying out the invention]

[0009] At the upper part of the gable end 9 of the multi-story greenhouse near the valley, a gable end truss beam 8 is positioned relative to the gable end 9 in the horizontal direction across the entire width of the gable end 9 of the multi-story greenhouse. The gable end truss beam 8 is attached by connecting or contacting the outer chord 8a to the valley gable post 3, side gable post 2, gable post 6, and gable intermediate post 7. Between the outer chord 8a and the inner chord 8b, which is arranged at a constant parallel interval, lattices 8c are placed in appropriate numbers with an inclination of 30 to 75 degrees, forming one or more continuous triangles on both sides from the center of the opening toward the valley and the side. This constitutes the gable end truss beam 8, which receives the wind pressure acting on the gable end 9 of the greenhouse at the middle of the greenhouse height and transmits that force to the entire greenhouse through the gable from the valley girder beam 5. Furthermore, the end-face truss beam 8 needs to be of a width and height that does not obstruct passage, and a height suitable for attaching the main support wire (not shown) for cultivation. However, even if it is made higher, it does not have to be the same height if the top of the support post (not shown) is attached to the inner chord 8b of the end-face truss beam 8 and the main support wire is drawn from the middle of the support post. Also, the width does not have to be the same as the width of the passage. [Examples]

[0010] The following describes an embodiment with reference to attached drawing 1. 1 is the main body of the house, with side gable posts 2, valley gable posts 3, and side posts 2b and valley posts 3b erected at regular intervals in the depth direction. Next, valley girders 4 are attached to each post to connect them in the depth direction, and beams 10 are attached to each post to connect them in the width direction of the house. Next, roof arches 11 are attached at regular intervals from the gable face 9, and ridges 12 are fixed to the top of the roof arches 11 so that the spacing of the roof arches 11 is aligned. After the roof work is completed, gable posts 6 and intermediate gable posts 7 are erected along the gable face 9. Between the second post in the depth direction from the side gable posts 2 and valley gable posts 3 on the gable face of each column row, valley gable beams 5 are placed under the valley girders 4, and the gable face truss beams 8 are positioned by connecting or contacting the valley gable beams with the side gable posts 2, valley gable posts 3, gable posts 6 and intermediate gable posts 7. The outer chord 8a of the gable truss beam 8 is attached by connecting or contacting the side gable column 2, valley gable column 3, gable column 6, and gable intermediate column 7. Between the outer chord 8a and the inner chord 8b, which is placed at regular intervals from the outer chord 8a, an appropriate number of lattices 8c are arranged to form a continuous triangle, thereby constructing the gable truss beam 8. As described above, the assembly of the gable truss beam 8 is the last step, but just as the effect and result are the same even if the installation of beam 10 is done before the installation of the roof arch 11, the effect and result are the same regardless of the order of assembly.
