[Effect] The suspension bolt can be safely supported without using auxiliary metal fittings.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a suspension support metal fitting used for supporting a suspension bolt or the like on a construction material such as a shape steel.

[0002]

[Prior art]

 Conventionally, in order to support a hanging bolt on a shaped steel, an auxiliary metal fitting is attached to a side-substantially U-shaped supporting metal fitting (registered trademark Pilac) previously proposed by the applicant, and the end of the hanging bolt is attached to this auxiliary metal fitting. It is fixed with screws (see No. 1-2129408, Kaikaihei).

[0003]

[Problems to be solved by the device]

 If the suspension bolt is suspended from the conventional support bracket without attaching the supplementary bracket, the end of the suspension bolt hits the construction material, and before the load is applied to the suspension bolt, it is between the support bracket and the construction material. A gap is generated (see symbol S in FIG. 4A). Furthermore, if a load is applied to the suspension bolt in this state, the gap between the support fitting and the construction material expands, and the tip of the suspension bolt may separate from the construction material (see symbol S in Fig. 4 (b)). reference). Therefore, conventionally, an auxiliary metal fitting is interposed between the support metal fitting and the construction material so that the tip of the hanging bolt does not directly hit the construction material. However, when the support metal fittings and the auxiliary metal fittings are used in combination as described above, there is a disadvantage that the labor required for the work is increased and the manufacturing cost is increased.

Therefore, the present invention was created in order to solve the above-mentioned problems, and an object thereof is to provide a suspension support fitting that can safely support a hanging bolt without using an auxiliary fitting.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first means of the present invention is that an upper plate 1 and a lower plate 3 which face each other are continuously formed through a side plate 2 and a predetermined opening 4 is formed in the upper and lower plates 1 and 3. Is a support metal fitting that sandwiches the construction material Q and holds the construction material Q with pressure to fix the construction material Q on the upper plate 1, and penetrates the lower plate 3 with screw holes 6 for hanging bolts that support the hanging bolts P. That is, the hanging bolt screw hole 6 of the lower plate 3 is disposed closer to the side plate 2 than the fastening screw 5 of the upper plate 1.

The center position of the hanging bolt screw hole 6 of the second means is arranged so that the side plate 2 is 2 mm to 6 mm closer to the center than the core position of the fastening screw 5.

Further, the center position of the screw hole 6 for the hanging bolt of the third means is located at a position 22 mm from the open end of the lower plate 3 so that the side plate 2 is displaced by 4 mm from the core position of the fastening screw 5. The arrangement is the means for solving the problems.

[0008]

[Action]

 That is, according to the means of the present invention, the hanging bolt P is tightened toward the building material Q by the position of the hanging bolt P, which is arranged so that the side plate 2 is closer to the arm than the fastening screw 5 of the upper plate 1. In this case, the lower plate 3 is fixed without separating from the construction material Q.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In this invention support metal fitting, an upper plate 1, a side plate 2 and a lower plate 3 are continuous with each other to form a substantially U-shaped side surface. Then, a predetermined building material Q is sandwiched between the openings 4 formed by the upper and lower plates 1 and 3, and the building material Q is pressed by the fastening screw 5 provided on the upper plate 1 (see FIG. 1). At this time, the hanging bolt P is screwed into the hanging bolt screw hole 6 provided in the lower plate 3, and the upper end portion of the hanging bolt P is crimped to the building material Q (see FIG. 3).

The hanging bolt screw holes 6 for screwing the hanging bolts P are arranged such that the side plate 2 is closer to the crocodile than the fastening screw 5 of the upper plate 1. At this time, the center position of the hanging bolt screw hole 6 can be arranged closer to the side plate 2 within the range of 2 mm to 6 mm than the core position of the fastening screw 5.

In particular, as shown in FIG. 2, the center position of the hanging bolt screw hole 6 is 4 mm closer to the side plate 2 than the center position of the fastening screw 5 (reference numeral a in the figure), and the opening of the lower plate 3 is located. The highest strength was obtained at the position 22 mm from the end (reference numeral b in the figure). That is, when a load G of about 300 kg was applied to the suspension bolt P in this state, the metal fitting was inclined, but no gap was created between the construction material Q and the lower plate 3 (see FIG. 3B). . On the other hand, when a load G of about 300 kg was applied to the suspension bolt P of the conventional metal fitting, a gap was created between the construction material Q and the lower plate 3.

The hanging bolt screw hole 6 in the illustrated example is formed by a tap screw, but a nut may be fixed to the peripheral edge of the through hole penetrating the lower plate 3. A screw hole 7 for screwing the fastening screw 5 is also formed by a tap screw like the hanging bolt screw hole 6.

[0014]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above. That is, according to claims 1 to 3, it is possible to safely support the suspension bolt. Therefore, it is not necessary to use the auxiliary metal fittings that have been conventionally used, which saves the labor and reduces the cost.
