Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a floor assembly structure for fixedly connecting joists and side frame angles in a greenhouse.

[Prior art and its problems]

Conventionally, the fixed connection between the joists and the side frame angles in greenhouses has been done using screws. The problem remains that it is not strong enough. Another drawback is that it cannot be completely assembled unless you are an expert.

[Means for solving problems and their effects]

In order to solve the above-mentioned problems, the present invention fixedly connects the joist 2 and the side frame angle 1 using a wedge-shaped fastener 5 having a W-shaped cross section. By adopting such a structure, each member can be disassembled and sold as a set, allowing the user to easily assemble it by themselves, and also providing sufficient assembly strength.

[Description of Examples]

In the drawing, 1 is the side frame angle of the greenhouse, 1a is the upright part, and 1b is the horizontal part. 2 is the joist, 3
is a column, which is fitted into the column attachment part 2a of the joist fixture 4. The joist fixture 4 consists of an inner wall 4b, an outer wall 4c, a bottom surface 4d, and an angle engagement part 4e.
A notch 4f is cut out in the outer wall 4c, and a square hole 4g is bored in the outer wall 4c.

Reference numeral 5 denotes a tightening tool which is driven between the joist 2 and the horizontal portion 1b of the angle 1 after the joist 2 is inserted into the notch 4f and the square hole 4g. The sides are wedge-shaped as shown in Figure A.
Reference numeral 6 denotes a floor plate, one side of which engages with the angle engagement portion 4e of the joist fixture 4, and is placed on the joist 2 and the tightening tool 5. 7 is a pot, etc.

Next, the assembly order will be explained.

First, the joist fixture 4 is attached to the side frame angle 1 in such a way that its column attachment part 4a fits into the upright part 1a of the angle 1.

Next, the joist 2 is inserted into the notch 4f of the joist fixture 4 and the square hole 4g.

Next, attach the tightening tool 5 to the horizontal part 1 of the side frame angle 1.
b and the joist 2 to fixedly connect the joist 2 and the angle 1.

[Effect of idea]

Since the wedge-shaped fasteners 5 with a W-shaped cross section are used to tightly connect the joists 2 and the side frame angles 1, the joining operation is easy, and if they loosen a little, you can immediately tighten the fasteners 5 by driving them in again. The tightening strength can be restored.

Claims (1)

[Claims for utility model registration] Pillar attachment part 4a, inner wall 4b, outer wall 4c, bottom surface 4
d. Using a joist fixture 4 consisting of an angle engagement part 4e, with a square hole 4g bored in the outer wall 4c and a notch 4f cut out in the inner wall 4b, the pillar attachment part 4a of the joist fixture 4 is connected to the side frame angle 1. After engaging the angle engaging portions 4e with the horizontal portions 1b of the angle 1 in the upright portions 1a, insert the joists 2 into the notches 4f and square holes 4g, and insert the wedge-shaped tightening tool 5 with a W-shaped cross section. A greenhouse floor structure characterized in that the joists 2 and the side frame angles 1 are tightened.
