Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting reinforcement used for hoisting an object to be hung such as a bay window unit.

[0002]

2. Description of the Related Art As an object to be lifted which is required to be lifted for mounting work, there is, for example, a bay window unit described in Japanese Utility Model Publication No. 60-17496. This bay window unit is a combination of a wooden frame structure and a plastic sash.

In such a bay window unit, for example, an eyebolt is attached to the roof, a hanging wire is hung on the eyebolt, and the eyebolt is lifted by a crane or the like.

[0004]

However, in the object to be hung such as the above-mentioned bay window unit, since the rigidity of the whole is low, there is a risk of deformation or damage at the time of hoisting.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a hoisting reinforcement which can prevent deformation and damage of the object to be hoisted during hoisting.

[0006]

In order to achieve the above object, the hoisting reinforcement according to claim 1 is used for hoisting an object to be hoisted having an upper horizontal member and left and right vertical members. A tool, which is a reinforcing member main body which is slanted and fixed between the upper horizontal member and the vertical member, and a bolt which is erected on a portion of the reinforcing member main body that is in contact with the upper horizontal member, A lifting eye nut screwed to the bolt is provided.

According to a second aspect of the present invention, there is provided a hoisting reinforcement according to the first aspect, wherein the object to be hung is a bayonet unit, and the upper horizontal member of the bayonet unit and the roof have the above-mentioned features. It is characterized in that a hole portion through which the bolt penetrates is provided, and the eye nut is screwed to the tip end portion of the bolt that penetrates the hole portion and projects onto the roof through a pedestal.

[0008]

According to the hoisting reinforcer according to the first aspect of the present invention, the hoisting reinforcer has a reinforcing tool main body which is slanted and fixed between an upper horizontal member and a vertical member of an object to be hung. Since a lifting eye nut is screwed onto a bolt that is erected on a portion of the main body that is in contact with the upper horizontal member, it is possible to easily lift an object to be hung, and at the same time, the reinforcement body Functions as a brace and improves the rigidity of the entire suspended object, so that it is possible to prevent deformation or damage of the suspended object during lifting.

According to a second aspect of the present invention, in the hoisting device for lifting, the object to be hung is a bayonet unit, and the upper horizontal member and the roof of the bayonet unit are provided with holes through which the bolts pass. Since the eye nut is screwed to the tip of the bolt projecting on the roof through the hole through the pedestal, the eye nut can be stably mounted on the roof, It is possible to easily lift the bay window unit while preventing deformation and damage.

[0010]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a bay window unit exemplified as a suspended object.

A fixing piece portion 14 having a plurality of small holes 13 abutting on the lower surface of the upper horizontal member 2 and fixed with screws or nails is integrally formed at an angle of about 45 degrees, and the bolt is attached to the fixing piece portion 14. 11 is vertically penetrated from below, and its head 11a
Is erected by fixing it to the lower surface of the fixed piece portion 14 by welding or the like. Further, a fixing piece portion 16 having a plurality of small holes 15 which is brought into contact with the side surface of the vertical member 3 and fixed with screws or nails is integrally formed at the other end of the reinforcement body 10 at an angle of about 45 degrees. ing.

The upper horizontal member 2 and the roof 6 are provided with holes 17 through which the bolts 11 vertically penetrate at positions corresponding to the bolts 11, and the bolts 11 are reinforced by inserting the holes 11 into the holes 17. The tool body 10 is slanted over the upper horizontal portion 2 and the vertical portion 3 so that the fixing piece portions 14 and 16 at both ends are fixed. The eye nut 12 is screwed to the tip of the bolt 11 that penetrates the hole 17 and projects onto the roof surface 5 of the roof 6 via the pedestal 18.

As shown in FIG. 3, the pedestal 18 is formed of a metal plate material in the shape of a hollow wedge, and the roof surface 5 is formed.
The lower surface portion 18b is an inclined surface that is substantially parallel to the roof surface 5 so that the upper surface portion 18a becomes a substantially horizontal surface when placed on the top. The upper surface portion 18a and the lower surface portion 18 of the pedestal 18
b, holes 19a, 19 through which the bolt 11 is inserted.
b is provided, and the hole portion 19b of the lower surface portion 18b has a larger diameter than the hole portion 19a of the upper surface portion 18a. The eye nut 12 is the bolt 1 as shown in FIG.
1 is formed by attaching a ring 22 to a nut body 21 having a female screw hole 20 into which 1 is screwed.

In the hoisting reinforcement 9 constructed as described above, a pair of reinforcement main bodies are respectively fixed to the upper side corners of the opening 7 of the bay window unit 1 in a bracing manner, and a pair of projections are projected on the roof 6. The eye nuts 12 are attached to the respective bolts 11 of FIG. Therefore, as shown in FIG. 5, the suspension wire 23 is hung over both eye nuts 12,
The hanging wire 23 may be hung up by hanging it on the hook 24 of the crane, whereby the bay window unit 1 can be easily hung up.

As described above, according to the hoisting reinforcing tool 9, the hoisting tool main body is slanted and fixed between the upper horizontal member 2 and the vertical member 4 of the window unit 1 which is the object to be hung. The upper horizontal member 2 of the reinforcement body 10
Since the eye nut 12 for lifting is screwed to the bolt 11 that is erected at the portion that comes into contact with, the bay window unit 1 can be easily lifted, and the reinforcing device main body 10 functions as a bracing, Bay window unit 1
Since the overall rigidity is improved, it is possible to prevent deformation and damage of the bay window unit 1 at the time of lifting. Further, the upper horizontal member 2 and the roof 6 of the bay window unit 1 are provided with a hole portion 17 through which the bolt 11 penetrates.
The eye nut 12 is screwed to the tip of the bolt 11 which penetrates 7 and projects onto the roof 6 through a wedge-shaped pedestal 18 which is placed on the roof surface 5. It can be stably attached to the sloping roof surface 5.
