Description

[Technical field]

[0001] The present invention relates to a new vertical curing material mounting fixture. More specifically, it relates to a vertical curing material mounting fixture that can be easily installed and removed in a short time even by an unskilled worker, and that can be firmly fixed to both a curing net and a scaffolding support. [Background technology]

[0002] Article 519 of the Industrial Safety and Health Act states that "measures to prevent falls from openings, etc. The law stipulates that "Employers must provide fences, handrails, covers, etc. at the edges of work floors and openings that are two meters or higher and that may pose a danger to workers due to falls." In other words, for construction scaffolding, it is mandatory to attach vertical protective materials (protection sheets, protective nets, etc.) to the scaffolding supports.

[0003] Protection nets are vertical protection materials for scaffolding that serve the purpose of preventing objects and people from falling, reducing noise, providing privacy, and preventing scattering.

[0004] Generally, vertical curing materials (such as curing nets) are usually square-shaped with rings at the four corners. The curing nets are tied together with the scaffolding supports with binding strings via the rings of the vertical curing materials. When using such binding strings, a lot of work (e.g., tying work) is required, and both installation and removal of the curing sheet members are difficult.

[0005] In contrast to such conventional technology, for example, Patent Document 1 discloses a curing sheet mounting bracket that "allows the curing sheet material to be easily attached and removed without much effort, can firmly attach the curing sheet material to a support, is easy to maintain, and can be used any number of times" (specification paragraph 0005, abstract, etc.).

[0006] Specifically, as shown in Figures 5(B)-(C), this protective sheet mounting bracket is characterized in that "it is formed by bending a bendable wire 11, and is used when attaching and disposing a protective sheet member such as a protective net 51 to a support 50 made of a pipe member or the like, and comprises a support mounting part 12 obtained by bending the wire 11 into a ring shape until both end portions 13, 14 intersect with each other, and a pair of opposing hook parts 16, 17 obtained by bending each of the parts located on the outside of the support mounting part 12 that are located further toward the tip than the intersection 15 of the both end portions 13, 14" (Claims, Abstract)

[0007] Patent Document 2 discloses a vertical curing material fixture that has a fastening part (e.g., a wedge-shaped fastening part) that fastens to a temporary scaffolding support and a hook part holder that has at least one pair of hook parts with a certain distance between the hooks. This vertical curing material fixture can be easily installed and removed in a short time even by an unskilled worker, and can firmly fix both the curing net and the scaffolding support.

[0008] [Patent Document 1] JP 2002-106175 A [Patent Document 2] Utility Model Registration No. 3247890 Summary of the Invention [Problem to be solved by the invention]

[0009] However, the vertical curing material mounting fixture disclosed in Patent Document 2 has the advantage and improvement of being able to be attached and removed quickly and easily compared to the mounting fixture disclosed in Patent Document 1, and being able to firmly fix both the curing net and the scaffolding support, but there is room for improvement in the strength of the hook part. Furthermore, with the conventional mounting fixture, when the curing net is attached, the ring part of the curing net moves back and forth while hooked on the hook part, which can cause bending, making it difficult to hang the curing net while maintaining sufficient tension. In other words, there was still room for improvement in the strength and fixation of the protective net with conventional mounting fixtures.

[0010] After extensive research into the problems with conventional protective sheet mounting brackets and binding strings, the inventors discovered that by providing a contact portion connected to a pair of hook portions (an upper hook portion and a lower hook portion), strength is greatly improved and, when the protective net is attached, the ring portion of the protective net does not move back and forth while hooked on the hook portions, or moves less so, making it less likely to become sagged, and thus completed the present invention. In other words, the object is to provide a vertical protective material mounting fixture which can be easily installed and removed in a short time even by an unskilled worker, has improved strength, and can hang and fasten a protective net while maintaining sufficient tension. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the vertical curing material mounting fixture according to the present invention will be described in detail with reference to the drawings as appropriate.

[0015] The vertical curing material mounting fixture of the present invention is primarily used when attaching vertical curing materials to temporary scaffolding, and more specifically, it is fastened to the scaffolding support and used by hanging the hook portion on the ring portion of the vertical curing material.

[0016] Here, the "vertical curing material" is not particularly limited as long as it is a vertical curing material used at building sites and various construction sites, and may be a sheet-like material without mesh or a net-like material with mesh (mesh sheet). Specific examples include curing sheets, curing nets, soundproofing sheets, shielding sheets, signboard sheets, and advertising sheets.

[0017] As shown by reference numeral 10 in FIG. 1, the vertical curing material mounting fixture of the present invention is composed of a fastening portion 1, a hook portion holding portion 3 having at least one pair of hook portions 2, and an abutment portion 4 for abutting the curing sheet hooked to the pair of hook portions (2), and may have other components as necessary.

[0018] The materials for these members are not particularly limited and can be appropriately selected, and examples thereof include metal and hard plastic.

[0019] The fastening part 1 is a member for fastening to a temporary scaffolding support. When the fastening part 1 is a wedge-shaped fastening part, it is desirably made of a metal such as iron, from the viewpoint of fastening to the insert part (pocket metal fitting, piece) of the wedge-fastening type scaffolding by hammering it in and of the requirement for durability.

[0020] Moreover, since they are often used outdoors and require rust-resistant properties, it is preferable that they be made of stainless steel or iron with a galvanized surface treatment.

[0021] As shown in Figures 1(A) and (B), the fastening part 1 is typically a wedge-shaped fastening part that is fastened by being driven with a hammer or the like into a scaffolding support fastening part 5a (pocket metal fitting, link) provided (usually fixed by welding) on ​​a scaffolding support 5 (building material). However, there are no particular limitations as long as it is fixed to the scaffolding support with sufficient strength; in addition to the wedge-shaped fastening part, screws and clamps are examples.

[0022] Also, the numbers 2a and 2b in Fig. 1(A)-(B) indicate an upper hook portion and a lower hook portion, respectively. Here, the upper hook portion and the lower hook portion face each other with a certain distance (the distance between the hook portions) therebetween to form a pair of hook portions 2. The hook portions 2a and 2b are used to hook onto (hang) ring portions provided in the vicinity of the square corners of the vertical curing material and to fix the vertical curing material. Also, the distance is adjusted taking into consideration the shape of the ring portions of the vertical curing material and the distance from the ring portions to the sides of the vertical curing material.

[0023] In the vertical curing material fixture according to the present invention, at least one pair of the hook parts 2 is required (i.e., two hook parts, an upper hook part and a lower hook part). The number of pairs of hook parts can be selected as appropriate, but generally, since the vertical curing material fixture needs to hang and fasten four vertical curing materials at each ring part, it is desirable to have two pairs (i.e., four hook parts).

[0024] As shown by the reference number 3 in Figs. 1(A) and 1(B), the pair of hook portions 2 are fixed to a hook portion holder. Here, the shape of the hook holder is not particularly limited, but it is preferable that the hook holder has a flat shape (rectangular shape).

[0025] The hook holder shown in FIG. 1 has a pair of hooks 2 fixed thereto, and the distance between them cannot be adjusted. For this reason, it is necessary to adjust the distance between them appropriately, taking into consideration the shape of the ring of the vertical curing material and the like. On the other hand, in FIG. 2, there are a plurality of holes 4, which are used to fix the end of the L-shaped hook that is not bent when it is inserted. Here, the fixing means may be a form in which the end of the hook and the inside of the hole are threaded and fixed with a screw, or a form in which the end of the hook and the hole are engaged (fitted) with each other. In this form, the distance (separation distance) between the upper hook and the lower hook can be freely adjusted.

[0026] Also, the reference number 4 in Figures 1 and 2 indicates a contact part. The contact part comes into contact with the protective sheet hung on the pair of hook parts (2). When the protective net is hung, as shown in Figure 3, it is difficult for bending to occur, and the hanging can be performed while maintaining sufficient tension, and the strength of the vertical protective material mounting fixture can be improved. 1 and 2, the abutment portion 4 is connected to the upper hook portion 2a and the lower hook portion 2b. The connecting method is not particularly limited, but it is preferable that they are connected by welding.

[0027] FIG. 3 is a side view (FIG. 4(A)) and a front view (FIG. 4(B)) showing the state when the vertical protective material mounting device 10 of the present invention is attached to a temporary scaffolding support 5 and a vertical protective material (curing net) N is further attached.

[0028] As shown in FIG. 4, the hook portions 2a and 2b are hooked onto a ring portion R of a vertical curing material (curing net) N when in use.

[0029] Here, by reducing the distance between the hook portions, the tension of the vertical protective material (protection net) can be increased, and conversely, by increasing the distance, the tension of the vertical protective material (protection net) can be decreased. [Industrial Applicability]

[0030] According to the present invention, it is possible to provide a vertical protective material mounting fixture that can be installed and removed easily and quickly even by unskilled workers, has improved strength, and can hang and secure the protective net while maintaining sufficient tension.
