Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fall prevention net for constructing a wooden building,
That is, the present invention relates to a metal fitting for tensioning a curing net.

[Prior Art] In a wooden building, it is common to build a framework and a shed at a stretch once the lower shed work and ground foundation work for structures such as columns and beams have been completed.

This erection is usually completed in one day, after which the braces are installed while showing the verticality and horizontalness of the structure, roofing and outer walls are constructed, and then the floor is laid. .

As mentioned above, there is a considerable number of days from the time of building to the time when boards are laid on the floor, and during that time, various tasks such as roofing, studs and bracing must be done. No
During the work, after-work such as a worker falling from the opening of the floor or ceiling of the second floor and the material falling.

In recent years, concrete is often placed on the entire foundation of a building for reasons such as prevention of moisture.In such a case, the above-mentioned crash accident is a serious problem that may lead to serious injury or even death. Has become.

In order to prevent such a fall accident, a protective net for fall prevention has been conventionally installed at the floor opening etc. before the floor is stretched, and as shown in Fig. 10, the worker who has fallen is caught and injured. It is designed to prevent this.

[Problems to be solved by the invention] Conventionally, when installing this type of curing net,
As shown in the figure, the net periphery was attached to the pillars and beams with a binding material such as rope.

However, the above-mentioned conventional binding method has problems that not only the binding is troublesome, but also the binding tends to be incomplete.

The present invention has been made to solve the above-mentioned conventional problems. The purpose of the present invention is to eliminate the need for special metal fittings for net tensioning, and to connect the pillars and beams with a conventional one. It is an object of the present invention to provide a mounting bracket for a curing net that can be quickly and reliably mounted and bound by using the existing reinforcing metal or the like used in.

[Means for Solving the Problems] The mounting hardware for the curing net of the present invention is provided with a circular ring on a battledore bolt that is fixed to a wooden structural material such as a pillar or a horizontal material in a wooden building, or a wooden building. A round ring is provided on a washer for bolts that is fixed to a wooden structural material such as a pillar or a horizontal member,
Furthermore, it is composed of two seat plates fixed to wooden structural materials such as columns and horizontal members in a wooden building, and a curved rod that integrally connects these seat plates, and also in a wooden building. A circular ring is provided on a coach screw for fixing to a wooden structural material such as a pillar or a horizontal member.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a metal plate, and a bolt 2 is integrally fixed to one side surface of the metal plate by welding to form a battlement plate bolt as a whole.

The fixing side end of the bolt 2 is bent in a ring shape to form a round ring 2a.

As shown in FIG. 2, the round ring 2a may be formed separately from the bolt 2 and fixed to the metal plate 1 by welding.

Further, as shown in FIG. 3, the round ring 2a may be formed as a punched hole by bending the end portion of the metal plate 1 at a substantially right angle.

Since the present embodiment is configured as described above, in order to stretch the curing net using this, as shown in FIG. A circular ring 2a provided on the battledore bolt while being fixed and reinforced by the connection with a material (for example, a beam) or the connection between a large beam and a small beam
Then, the curing net N is bound through a hanging net R such as a binding rope.

FIG. 5 shows another embodiment, in which a circular ring 4 is integrally connected and fixed to a washer 3 of a bolt V which is fixed to a wooden structural material such as a pillar or a horizontal member. It is fixed with bolts, and the suspension steel of the curing net is bound to the circular ring 4. As shown in FIGS. 6 (A) and (B), a method for manufacturing this mounting bracket is to form a flat bar by leaving the central portion of the round bar steel material B and pressing both end portions from the arrow direction. To do. Both flat plate portions are oriented in a direction of approximately 90 ° to each other. Finally, punch out holes in the flat plate to complete.

FIG. 7 shows an embodiment of a metal fitting formed by integrally connecting two washers 5 with a curved rod 6. The washer 5 is fixed to a beam or the like and fixed to the curved rod 6 as well. Bundling the hanging steel of the net. As a method of manufacturing this metal fitting,
As shown in FIG. 8, both ends of the round bar steel B are pressed in the direction of the arrow to leave the washer 5, and the washer 5 is bent in the direction of the arrow to form the curved rod 6.

This pressing and bending can be performed by a one-step pressing operation.

9 (A) and 9 (B) show an embodiment of a mounting member in which a circular ring 8 is integrally fixed to the head of the coach screw 7.

[Advantages of the Invention] The present invention has an advantage that a mounting ring can be mounted quickly and surely because a reinforcing ring fixed to a column or a beam joint is provided with a round ring for mounting a curing net.
