Description

The present invention relates to a scaffold for a worker to safely perform work such as maintenance on a corrugated slate roof (inclined) adopted for a roof of a factory or a warehouse.

A slate roof is a roof made of a mixture of fibers other than asbestos such as pulp (previously asbestos was also used) and cement, and because it is lighter than a so-called tile roof, it is earthquake resistant. It is a popular roof because of its high height. From the viewpoint of the cross-sectional shape of the slate roof, it may be classified into a corrugated slate roof (the present invention is applied to this type of roof) and a flat slate roof. The slate roof is thin with a thickness of about 5 mm (Japanese roof tiles: 10 mm to 20 mm) and has the advantage of being lightweight, but it is not strong enough and the main component is cement, so it absorbs rainwater unless it is painted. It has the disadvantage of being easily cracked because it becomes brittle. That is, the durability and waterproofness are low, and specifically, there is a concern that deterioration symptoms such as cracks may occur due to the influence of rain, wind, ultraviolet rays, and the like.

By the way, the life of the slate roof is said to be about 15 to 20 years (maintenance such as painting is required about once every 10 years: the manufacturer's warranty period for the slate roof is about 10 years at the longest). In view of this situation, it can be said that regular maintenance is important to prolong the life of the slate roof. On the other hand, the slate roof is thin and easily cracked with a thickness of about 5 mm (Japanese roof tiles: 10 mm to 20 mm), so if the worker steps on a part that is out of the steel frame during maintenance, the slate roof will crack and the slate will crack. There is also a risk that workers will roll off the slate roof due to the cracking momentum of the roof. In fact, during the dismantling work of a one-story warehouse, a worker who was moving on the slate roof stepped on the slate roof, crashed from a height of about 6 m, and smashed his head (cerebral contusion) on the concrete floor. Has also been reported. Based on the above situation, it is necessary to ensure the safety of workers during maintenance work, and work on scaffolding that can be easily installed, in short, on corrugated slate roofs used for roofs of factories and warehouses, etc. There is a need for easy-to-install scaffolding for safe operation.

In Patent Document 1, the scaffolding board is lightweight and can be easily installed on the slate roof, and the scaffolding board is installed on the slate roof for the purpose of ensuring a passage for walking (in the case where the scaffolding board is installed on the slate roof). As a result of repeated sincere research from the viewpoint of eliminating the line contact between the scaffolding board and the slate material and making surface contact with the aim of reducing the weight and improving the installability of the scaffolding board, the underside of the scaffolding board is made of slate. As a structure that makes surface contact with the slate material as a wave shape that follows the wave shape, it has strength as a scaffolding that reliably receives the load of the worker, and the scaffolding plate does not slip, so that the worker can step on with confidence. "Scaffolding board on a slate roof (Patent Document 1: Name of the invention)" is disclosed.

Japanese Unexamined Patent Publication No. 2007-239415

The invention according to Patent Document 1 adopts a configuration in which the lower side of the scaffolding plate has a wavy shape along the wavy shape of the slate and is brought into surface contact with the slate material. Certainly, it seems possible to secure a passage for workers to walk. However, the worker must perform maintenance and other work on a scaffolding (walking passage) having the same inclination as the angle of the roof. That is, it is not possible to secure the levelness of the worker, and the angle of the standing position of the worker depends on the angle of the roof. Seems to be painful for workers and leads to a decrease in work efficiency.

An object of the present invention is to allow an operator to safely perform maintenance and the like on a corrugated slate roof (inclined) adopted for roofs of factories and warehouses, that is, corrugated slate roofs that are fragile and therefore have a risk of falling. The purpose is to provide a corrugated slate roof scaffold that can be done and is easily installed.

In order to solve the above problems, the invention described in claim 1 is an apparatus for installing a scaffolding plate for securing a scaffolding for a worker when performing roof repair work on a corrugated slate roof. A first mounting member including a stretchable base rod-shaped member, a flat plate member having a notch installed at one end of the base rod-shaped member, and a cushion member attached to the lower surface of the flat plate member, and the above. A second mounting member having a flat plate member having a notch portion installed at the other end of the base rod-shaped member and a cushion member bonded to the lower surface of the flat plate member, the first mounting member, and the second mounting member. A first mounting member installed between the mounting members is provided, and the scaffolding plate installation base includes a pedestal member for directly mounting the scaffolding plate, a scaffolding flat plate member having a notch, and the scaffolding flat plate. The scaffold for a corrugated slate roof is characterized by including a cushion member attached to the lower surface of the member and an angle fixing member for fixing the angle formed by the pedestal member and the scaffolding flat plate member. Is to be. In this specification, the surface in contact with the slate roof at the time of installation is defined as the lower surface of the flat plate member (the lower surface of the scaffolding flat plate member).

The invention according to claim 2 is characterized in that, in the invention according to claim 1, the cushion member is a corrugated slate roof scaffold having a cross-sectional shape that matches the cross-sectional corrugated shape of the slate roof. ..

The invention described in claim 3 is the invention described in claim 1 or 2, characterized in that it is a corrugated slate roof scaffold in which a handrail is provided on the corrugated slate roof scaffold.

The corrugated slate roof scaffold according to the present invention is an instrument for installing a scaffold plate for securing a scaffold for a worker when performing roof repair work on a corrugated slate roof which is a sloped roof. A first mounting member having a stretchable base rod-shaped member and a flat plate member (having a notch) and a cushion member attached to the lower surface of the flat plate member is installed at one end of the base rod-shaped member to form a base rod. At the other end of the member, a second mounting member having a flat plate member (having a notch) and a cushion member bonded to the lower surface of the flat plate member is installed, and the first mounting member and the second mounting member are mounted. A scaffolding board installation stand is installed between the members. Further, the scaffolding board installation base includes a pedestal member for directly mounting the scaffolding board, a cushion member attached to the lower surface of the scaffolding flat plate member (having a notch) and the scaffolding flat plate member, and the pedestal member and the scaffolding flat. It is provided with an angle fixing member for fixing the angle formed by the face plate member.

Therefore, by adjusting the length of the stretchable base rod-shaped member, the notch portion of the scaffold for the corrugated slate roof (first mounting member, first) at the position of the bolt for fixing the slate roof during construction of the slate roof. (2) The mounting members and the scaffolding board installation base (3 locations in total) can be installed in the same position. In addition, after the tubular nut is installed in advance on the bolt part installed on the slate roof itself, the notch part of the scaffold for the corrugated slate roof (first mounting member, second mounting member, scaffolding plate). It may be installed by aligning the positions of the installation bases (a total of 3 locations).

The scaffolding plate installation base includes a scaffolding flat plate member and a cushion member (the first mounting member and the second mounting member also have a flat plate member and a cushion member), and moreover, the cushion member. Has elasticity and has a cross-sectional shape that matches the cross-sectional corrugated shape of the slate roof, and has a shape like a "scaffolding" so that the weight of the worker does not concentrate on one point on the slate roof. Has been done. Furthermore, the angle fixing member for fixing the angle formed by the scaffolding member and the scaffolding member and the scaffolding flat plate member (which also has the effect of supporting the weight of the worker) allows the worker to be affected by the inclined state of the roof. You can work in parallel with the ground without any trouble. By installing the handrails for workers on the corrugated slate roof scaffolding, the workers can get a sense of security that arises from the sense of stability during work.

It is a side view, the front view, and the top view of the scaffold for the corrugated slate roof which concerns on this invention. It is a side view of a state where a handrail is installed on a scaffold for a corrugated slate roof. It is a side view of the state where the scaffolding for a corrugated slate roof is installed on the corrugated slate roof, and is the figure which showed the state where the scaffolding for a corrugated slate roof is installed on the slate roof.

<Structure of corrugated slate roof scaffolding>
Hereinafter, the corrugated slate roof scaffold 10 according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a top view (a), a side view (b), and a front view (c) of the corrugated slate roof scaffold 10 according to the present invention.

As described in FIG. 1, the corrugated slate roof scaffold 10 has a stretchable base rod-shaped member 20 and a first mounting member 60 (a flat plate member having a notch 30) installed at one end of the base rod-shaped member 20. 40, a cushion member 50 bonded to the lower surface of the flat plate member 40), and a second mounting member 70 (flat plate member 40 having a notch 30) installed at the other end of the base rod-shaped member 20. And a cushion member 50 bonded to the lower surface of the flat plate member 40), and a scaffolding plate installation base 80 installed between the first mounting member 60 and the second mounting member 70 (near the center). I have.

The base rod-shaped member 20 is configured to be slidable in the longitudinal direction, and is, for example, a plurality of nested square pipes provided with fixing screws (wing bolts, wing nuts, etc.) for adjusting the length (FIG. In 1, it is composed of three square pipes, but it may be composed of three or more square pipes), and any configuration can be taken as long as it can be expanded and contracted. Is also good. The length of the base rod-shaped member 20 can be freely set, but it is about 2100 mm in the fully extended state, and the thickness is about 50 mm to 70 mm.

The first mounting member 60 is bonded to the flat plate member 40 having the notch portion 30 and the lower surface of the flat plate member 50 (in this specification, the surface in contact with the slate roof at the time of installation is defined as the lower surface). The cushion member 50 is provided. The cushion member 50 has a shape corresponding to the cross-sectional corrugated portion of the corrugated slate roof, and it is preferable that the first mounting member 60 is installed on the entire surface facing the cross-sectional corrugated portion of the corrugated slate roof. The material of the cushion member 50 is preferably urethane resin in consideration of strength, elasticity and the like, but other resins can be adopted as long as they have the functions of the present invention. The width of the first mounting member 60 is usually about two cross-sectional corrugated portions (300 mm to 350 mm) of the corrugated slate roof, but may be the width of three cross-sectional corrugated portions of the corrugated slate roof. , It may be wider than that.

The second mounting member 70 installed by sandwiching the first mounting member 60 and the scaffolding plate mounting base 80 has basically the same configuration as the first mounting member 60. The width of the second mounting member 60 is basically the same as that of the first mounting member 60. Similarly, the cushion member 50 is also characterized in having the same cross-sectional shape as the corrugated cross-sectional shape of the corrugated slate roof. That is, the cushion member 50 is formed in a shape like a "kamaboko" as a whole so as to match the cross-sectional corrugated shape of the slate roof from the upper surface. Even if the corrugated slate roof scaffolding 10 is configured by the two members (and the base rod-shaped member 20) of the second mounting member 70 and the scaffolding plate mounting base 80 without installing the first mounting member 60. good.

The scaffolding plate installation base 80 includes a pedestal member 90 for a worker to directly place a scaffolding plate for working and moving on the scaffolding plate installation base 80, a scaffolding flat plate member 100 having a notch portion 30, and a scaffolding flat plate member 100. A cushion member 50 attached to the lower surface of the scaffolding member 90 and an angle fixing member 110 for fixing the angle formed by the pedestal member 90 and the scaffolding flat plate member 100 are provided. The angle fixing member 110 will be designed according to the slope of the corrugated slate roof (for example, there are standards such as 4 inch slope, 5 inch slope, 6 inch slope, etc.) in order to secure the level during the work of the operator. .. It should be noted that the "○ dimension gradient" is expressed by a numerical value obtained by measuring how many rising dimensions there are with respect to a horizontal dimension of 10 inches. For example, "4 inch gradient" means that the rising dimension of the roof for a horizontal distance of 10 inch is 4 inch.

Further, the handrail 120 can be installed on the corrugated slate roof scaffold 10. FIG. 2 is a side view showing a state in which a handrail is installed on the corrugated slate roof scaffold 10. As described in FIG. 2, the handrail 120 is installed at a predetermined position of the base rod-shaped member 20 so as to stand upright in the vertical direction. The handrail 120 may be reinforced so as to be connected to the angle fixing member 110.

<Installation state of scaffolding for corrugated slate roof>
FIG. 3 shows a side view of the corrugated slate roof scaffolding 10 installed on the corrugated slate roof, and a state in which the (two) corrugated slate roof scaffolding 10 is installed (passing the scaffolding board) on the slate roof. It is a figure. First of all, as a premise, the corrugated slate (roofing material) that constitutes the corrugated slate roof is a steel structure that constitutes the main building of a factory or warehouse, and fasteners such as bolts and nuts (in short, the corrugated slate roof is a steel structure). It is attached by a member for fixing to the body).

When installing the corrugated slate roof scaffolding 10 on the corrugated slate roof, the base rod-shaped member 20 configured to be slidable in the longitudinal direction is slid in the longitudinal direction to bolt the corrugated slate roof (a notch corresponding to the bolt). The part 30 is provided) can be utilized as it is for installation. As described in FIG. 3, the corrugated slate roof scaffold 10 can be installed more stably by fitting the tubular nut into the bolt which is the fixing bracket for the corrugated slate roof.

The corrugated slate roof scaffold 10 is characterized in that it can be easily installed by installing a notch 30 installed so as to match the position of the fastener on the corrugated slate roof. .. Then, as described in FIG. 3, the corrugated slate roof scaffold 10 is placed by arranging a plurality of corrugated slate roof scaffolds 10 side by side so as to pass a scaffold plate between them. It is possible to secure the level during work. Further, by installing the handrail, the operator can obtain a sense of security resulting from a sense of stability during work. No matter how experienced a veteran craftsman is, he feels uneasy and cannot do perfect work on a roof where he does not know when a strong wind will blow.

<Effect of corrugated slate roof scaffolding>
In the present invention, since the "slate roof" is made of a material that is easily broken, it is easily broken by a heavy object, and there is a risk that the worker will roll down during the work (the worker who has risen to the slate roof is from the steel frame). If you step on a detached part, the slate roof will crack and the worker will fall, etc.), so we would like to improve it. And, I want to avoid installing full-scale safety equipment to ensure the safety of workers because the installation cost is too high, and moreover, I want to install it easily from the viewpoint of work efficiency. This is in response to the request from the field that we want to do it.

According to the corrugated slate roof scaffold according to the present invention, the length of the stretchable base rod-shaped member 20 is adjusted, that is, the length of the base rod-shaped member 20 is fastened when the slate roof is constructed. It can be easily installed by aligning it with the position of the mounting bracket (bolt). That is, at the position of the bolt for fixing the corrugated slate roofing material at the time of construction of the slate roof, the notch portion 30 of the scaffold for the corrugated slate roof (first mounting member 60, second mounting member 70, scaffolding board installation base 80). It can be easily installed by simply aligning the positions of (3 locations in total). In addition, after the tubular nut or the like is installed in advance on the bolt portion installed on the slate roof itself, the notch portion 30 (first mounting member 60, second mounting member 60) of the corrugated slate roof scaffold 10 is installed. The members 70 and the scaffolding board installation base 80 may be installed at the same positions (a total of three locations).

If you try to work on the roof without scaffolding or simply by placing the scaffolding board on the slate roof, the work quality may be very poor. The reason is that on a high and sloping roof, workers are concerned about protecting their own safety and cannot concentrate on the work at hand. If the workers cannot concentrate, there is a possibility that the work such as painting will be uneven, and the parts that are hard to reach at the edges may be completed just by performing the work properly. That is, no matter how experienced a veteran worker is, he cannot do perfect work on a roof where he does not know when a strong wind will blow.

Summarizing the above, the corrugated slate roof scaffolding 10 can ensure the safety of workers during maintenance work, and also has a notch 30 (first mounting member 60, second mounting member 70, scaffolding). For corrugated slate roofs that can be installed extremely easily by simply placing the board installation base 80) in the positions of the bolts (which may be covered with tubular nuts) on the corrugated slate roof. Scaffolding 10, in short, a corrugated slate roof scaffolding 10 that can be easily installed for safely working on a (sloping) corrugated slate roof used for roofs of factories and warehouses can be provided. It became like.

<Example of changing scaffolding for corrugated slate roof>
The scaffolding for a corrugated slate roof according to the present invention is not limited to the embodiment of the above embodiment, and is not limited to the above-described embodiment. The configurations of the member, the pedestal member, the scaffolding plate installation base, the scaffolding flat plate member, the angle fixing member, the handrail, and the like can be appropriately changed as necessary without departing from the spirit of the present invention. For example, the angle fixing member installed to ensure the level during the work of the operator according to the slope of the corrugated slate roof may have a length adjusting function.

Since the scaffolding for a corrugated slate roof according to the present invention exerts an excellent effect as described above, the operator can safely perform maintenance work on the corrugated slate roof adopted for the roof of a factory or a warehouse. It can be suitably used in the field of work on a scaffold for performing the above, particularly on a sloping roof.
