Abstract

PURPOSE:To prevent deformation, and reduce a cost by fitting a frame to the upper of a house unit freely to be disconnected, and hoisting the house unit for movement through this frame. CONSTITUTION:A unit hoisting reinforcing brace 1 consists of a square main frame 1a and reinforcing parts 1b stretched between the inside surfaces of the main frame 1a. Next, bolt holes for the insertion of jointing bolts 4a and a locking hole 1a for fitting of a wire 3 with hook of a crane are provided in a brace 1. Next, the brace 1 is placed on the upper end of a house unit 2, and is fixed by the bolts 4a, using girth bolt holes of the unit 2 or the like. The wire 3 is fitted in the locking holes 1a, and the unit 2 is hoisted by a crane, and is moved to a target position. Anchor bolt holes can be used to fit the frame to the upper and the lower surfaces of the unit 2 at need, or L-type frame or U-type frame can be used. Deformation of the unit in the inside direction is thereby prevented, and simultaneously, reinforcing beams of a unit itself is eliminated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing brace for lifting a housing unit, which is used when transporting or constructing a large housing unit that has been assembled in advance in a factory.

0002

[Prior Art] In prefabricated houses constructed using panels prefabricated at a factory based on predetermined standards, conventional methods generally include assembling each panel on site.
Alternatively, a unit construction method is used in which each panel is assembled in a box shape in advance at a factory to form a unit, which is then transported to the site and installed at a predetermined location. especially,
The latter unit construction method, in which units are installed on-site, has been increasingly adopted in recent years because it simplifies on-site construction and shortens the construction period.

By the way, when using the above-mentioned unit construction method, in order to lift the unit, a hanging hardware is attached to the upper core material of the wall panel that makes up the unit, and the unit is connected to the hanging hardware. By gathering the wires at one point and lifting this point with a crane, the entire unit can be lifted and installed at the desired location. Here, in a unit that is lifted and transported in this way, each wall panel to which the hanging hardware is attached may be damaged due to the weight of the unit itself.
Due to the inward tension, several reinforcing beams are usually installed between the wall panels to maintain their quality against this tension.

0004

[Problems to be Solved by the Invention] However, the reinforcing beams are necessary only when lifting the unit, and are essentially unnecessary at times other than when lifting the unit. In other words, such units are designed to exhibit sufficient strength when built into a house. Therefore, attaching such an originally unnecessary reinforcing beam not only causes a rise in material costs, but also increases the number of man-hours for manufacturing and attachment, leading to an increase in production costs.

The present invention was proposed in view of the above-mentioned circumstances, and its purpose is to eliminate unnecessary reinforcing beams and to prevent tensile force from being applied to the wall panel of the unit when it is lifted. To provide a reinforced brace for lifting a unit.

[0007]

[Means for Solving the Problem] The reinforcing brace for lifting the unit has a rectangular main body frame attached to the upper end of the wall, a reinforcing part provided across the inner surface of the main body frame, A removable fixing means is provided for fixing the upper end of the wall to the main body frame, and a locking part for locking a lifting member of the crane is provided at an opposite position of the main body frame. The solution to the above problem is to provide at least one pair.

[0008]

[Function] Since the reinforcing brace for lifting a unit according to the present invention has a rectangular frame shape with a reinforcing part, by attaching it to the unit by the fixing means,
This absorbs the tensile force due to the weight of the unit when it is lifted, and prevents tensile force from being applied between the wall panels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 in the figure indicates a reinforcing brace for lifting the unit of this embodiment.

A reinforcing brace for lifting a unit (hereinafter simply referred to as a reinforcing brace) 1 consists of a rectangular main body frame 1a attached to the upper end of a panel (wall) 2a forming a box-shaped house unit 2; The reinforcing portion 1b is provided to span between the inner surfaces of the main body frame 1a. The main body frame 1a is provided with a bolt hole (fixing means) 1c for fixing the upper end of the panel 2a, and a locking hole (locking hole) for locking the hooked wire (lifting member) 3 of the crane. Stop part) 1
d is a pair of opposing sides 1e, 1 of the main body frame 1a.
e is provided approximately at the center of each.

The main body frame 1a is formed in a shape whose bottom surface corresponds to the upper end surface of the wall of the house unit 2 to be lifted, and is made of a material having sufficient strength such as iron. The reinforcing portion 1b is made of the same material as the main body frame 1a, is formed in the shape of a cross connecting two sets of opposing corners of the main body frame 1a with diagonal lines, and is provided on the inner surface of the corner by welding or the like. It is. The bolt hole 1c is formed vertically through the main body frame 1a at a position communicating with the bolt hole 2b of the panel 2a.

In order to lift the house unit 2 using the reinforcing brace 1 constructed as described above, as shown in FIG. Place it and bolt hole 1c
and a bolt hole 2b formed vertically penetrating the core material 2c of the panel 2a. Here, bolt hole 2b
In this case, holes for bolts are used for mounting and assembling other units on top of the house unit 2. Next, the joining bolt 4a is inserted from above, and the nut 4b is fastened in the joining space 2e of the panel 2a to join them. In the same manner, all the panels 2a are joined to the reinforcing brace 1, and the hooks of the hooked wires 3 are inserted into the locking holes 1d, 1d, lifted up by a crane, and transported to the desired position.

According to the reinforcing brace 1 of the present embodiment, each panel 2a of the house unit 2 is connected to the bolt 4a and the nut 4.
Since it is always supported at a predetermined position by joining through b, the horizontal component of the lifting force does not act on the house unit 2 even during lifting, and the house unit 2 can be lifted without deforming. . In addition, since the method of joining the panel 2a is simple and detachable, repeated use eliminates the need to install reinforcing beams and reduces the manufacturing cost of the house unit 2.

[0015] In addition to the reinforcing brace 1, a reinforcing brace 1f having almost the same structure as this reinforcing brace 1 is prepared, and as shown in FIG. 2b may be used to attach the reinforcing braces 1f, thereby reinforcing both the upper and lower ends of the house unit 2. Furthermore, in the above embodiment,
Although an example has been shown in which the reinforcing brace of the present invention is applied to lifting a box-shaped unit, the present invention is not limited thereto, and can be applied to, for example, a house unit configured in an L-shape or a U-shape in plan view. It can also be used for lifting. and,
In that case, the corners of these house units should be reinforced with reinforcement braces 1.
can be handled in the same manner as in the previous embodiment.

[0016]

As explained above, according to the reinforcing brace for lifting a unit of the present invention, by being attached to the unit by the fixing means, it absorbs the tensile force due to the unit's own weight during lifting, and the reinforcement brace for lifting a wall panel Since tensile force is prevented from being applied between the parts, the house unit can be lifted without being deformed. Moreover, by repeatedly using the structure, unnecessary reinforcing beams can be eliminated, thereby reducing the manufacturing cost of the house unit.
