Description

[Detailed description of the invention] (Field of industrial application) This invention mainly relates to a workbench used as a scaffold when constructing a house or the like using the prefabricated construction method.

(Prior Art) As a scaffold to be placed on a roof, a scaffold for a slope described in Japanese Utility Model Application Publication No. 52-151639 is known.

This scaffolding is constructed by combining pipe materials to form a frame, and a wire mesh is placed on this frame.

On the other hand, in the prefabricated construction method, completed or semi-finished products such as exterior wall materials and frames are assembled using a crane or the like in order to shorten construction time.

For this reason, there is no longer a need for large-scale scaffolding such as one-sided scaffolding that is assembled facing the wall, and simple scaffolding such as stepladders and telescopic ladders that are easy to assemble, disassemble, and carry are mainly used.

(Problem that the invention aims to solve) However, in the case of a roof structure that consists of a ridge roof or a hinge, it is often necessary to erect a stepladder or ladder on the sloped roof. ,
Standing a stepladder or ladder in such a location is always dangerous and also reduces work efficiency.

In addition, in conventional scaffolding for sloped surfaces, pipe materials called sheath pipes are welded to the front two of the four corners of the frame that forms the structure, and a tube material called a sheath pipe is welded to form a substantially U-shaped structure frame. This is to fix the receiving plate to the moving frame. Therefore, in order to install this scaffolding on the roof, it is necessary to lift the frame to a certain extent onto the roof using multiple pipe materials, and the weight and size of the frame itself are This hindered assembly and disassembly work on the roof. Further, even during disassembly, the welded frame cannot be dismantled, which poses a problem in transporting and storing the disassembled structure.

Therefore, in view of the above-mentioned disadvantages, this invention makes it easy to stand on stepladders and ladders even in prefabricated construction, even if the roof structure consists of a roof with a ridge or a ledge, and it is extremely easy to assemble and disassemble. The purpose is to provide a workbench suitable for transportation and storage.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention has the following features:
A frame-shaped joint fitting 13 is provided on the side surfaces of the opposing legs 1, and wedge portions 14 that can be freely inserted into and removed from the joint fittings 13 are provided at both ends of the rod material. A mounting plate 17 is placed on the connected legs, suspension fittings 3 are provided at the four corners of the legs 1, and a pair of strings are formed to suspend the legs 1 from above the slope. One end of each of the shaped bodies 4 is attached to the hanging fitting 3, while a predetermined screw hole 2 provided at an appropriate position on the building is attached.
A means for solving the problem is that a stopper 6 having a locking bolt 23 that is screwed into the string member 2 is connected to the other end of the string-like body 4.

(Function) According to this invention, the pair of legs 1 having the ground plane portion 7 along the slope of the roof are connected to the joint fitting 1.
3 by a connecting member 16 having a wedge portion 14 that can be freely fitted and removed.

Then, the locking bolts 23 of the fasteners 6 are screwed into appropriate positions of the building constructed using the prefabricated construction method, so that the workbench of this invention is fixed on the sloped roof.

(Example) Hereinafter, an example of this invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 indicates legs, a frame 2 is provided horizontally above the pair of legs 1, and hanging fittings 3 are provided at the four corners of the frame 2.

Reference numeral 4 denotes a string-like body for suspending the leg 1 attached to the hanging fitting 3 above the slope of the roof, and at one end of the string-like body 4, a fastening fitting 6 equipped with means 5 for locking to a building is provided. There is.

The leg body 1 has a ground plane part 7 that follows the slope of the roof, and a rubber material or other cushioning material 8 may be attached to this ground plane part 7. In the illustrated example, the leg body 1 is constructed from a square piece made of a metal cylinder. That is, a grounding member 9 is provided with a cushioning member 8 attached to one side of a square piece to form a grounding surface portion 7, and a pair of supporting members 10 are provided on the upper surfaces of both ends of this grounding member 9.
The leg portions 11 are formed by standing them upright. A main member 12 made of a square material similar to the grounding member 9 is horizontally suspended above the leg portion 11 to constitute the leg body 1. Furthermore, the main material 12 at this time forms one side edge of the frame 2, which will be described later.

That is, the frame 2 has a substantially plate shape and is installed horizontally above the pair of legs 1, and in the illustrated example, the above-mentioned main member 12 forms one side edge of the frame 2. It is something that exists. A frame-shaped joint fitting 13 having a substantially U-shape in plan is provided on the opposing side surfaces of the supporting members 10 facing each other.

Then, a connecting member 16 is formed which has wedge portions 14 that can be freely fitted and detached into the joint fitting 13 at both ends of the square timber, and has an appropriate number of plate receiving pieces 15 on the lower side surface. The members 10 are connected to each other (see Fig. 1). Furthermore, each connecting member 16 and the main member 1
A mounting plate 17 made of a durable panel having a size that fits into each space divided by 2 and 2 is inserted into each space, and the frame 2 is mounted by placing it on the plate receiving piece 15. It is configured.

By configuring the legs 1 and the frame 2 in this way, they can be extremely lightweight and yet strong.

Furthermore, hanging fittings 3 are provided at the four corners of the leg body 1, and the leg body 1
A fastener 6 having a means 5 for locking to a building is provided at the other end of the pair of string-like bodies 4 that suspends the string from above the slope. At this time, the string-like body 4 and the leg body 1, or the string-like body 4 and the fastening fitting 6, can be attached and detached by means of a locking hook 18 or the like. It may also be used to fix it.

For the fastener 6, first, a receiving member 20 is formed from a square material similar to that used for the leg 1, and a securing member 2, which is a metal rod bent into a substantially U-shape, is attached to both ends of one side of the receiving member 20.
Both ends of 1 are fixed. and locking body 2
The string-like body 4 is attached to the tip of the receiving member 20, and means 5 for locking to a building is provided at an appropriate position on the receiving member 20.

The locking means 5 is constructed by providing a screw hole 22 in advance at an appropriate position in the aggregate of a building panel such as a wall, and screwing a locking bolt 23 into the screw hole 22 into the receiving material 20. This is a locking means 5. Further, the distal end portion of the locking body 21 to which the string-like body 4 is attached is bent into a substantially triangular shape, and a reinforcing plate 24 is attached to this distal end portion.
The strength of the locking body 21 is increased by spanning the locking body 21 (see FIG. 2).

Note that the screw holes 22 can be provided at any position when processing the material of the building panel, so for example, they can be placed at the lower edge of the window frame 25, under the eaves, etc. (See Figure 3).

(Effects of the invention) As described above, this invention has a substantially plate-shaped frame 2 installed horizontally on top of a pair of legs 1 having a contact surface 7 that follows the slope of the roof. You can secure a flat space even on a roof.

Furthermore, since the leg body 1 and the connecting member 16 can be freely fitted and removed, and the mounting plate 17 on the plate body receiving piece 15 is also freely attachable and detachable, the leg body 1 and the connecting member 16 can be attached and detached when not in use. It is also possible to separate the mounting body 17 and the mounting body 17, which is extremely convenient for storage and transportation.

Moreover, this invented workbench is fixed by screwing the locking bolt 23 of the fastener 6 into the screw hole 22 provided at the appropriate position of the building, so it is secure even on a steeply sloped roof. can be fixed to. For this reason, even in prefabricated construction where a roof has a different roof or a ledge, a stepladder or ladder can be easily and safely placed on the roof, and work can be done stably on the mounting plate 17. It becomes possible to do this. Furthermore, it goes without saying that an operator can directly stand on the mounting plate 17 and work thereon, and materials and the like can also be placed on it, so that it can be used in accordance with the working conditions.

Furthermore, since the ground plane 7 follows the slope of the roof, no matter what kind of roofing material is used, such as tiles, slates, or corrugated iron sheets, it is important to avoid protruding ridges along the slope. This makes it possible to position the legs 1 without damaging the roofing material.

Further, by providing the hanging fittings 3 at the four corners of the leg 1, the leg 1 etc. can be easily moved using a crane, so that work efficiency can be improved.

As described above, according to this invention, even in prefabricated buildings, etc., even if the roof structure is composed of a roof structure with a ridge roof or a ledge, it becomes easy to stand on a stepladder or ladder.
It has various practical effects such as being able to safely and easily stand a stepladder or ladder on a steeply sloped roof, being extremely easy to assemble and disassemble, and being suitable for transportation and storage. It is something.
