[Industrial applications]

 The present invention relates to an improved structure for assembling a reinforcing member for a precast concrete curtain wall.

[0002]

[Prior art]

 Precast concrete curtain walls are used in concrete wall materials for building structures. They are used as buried formwork (although the buried formwork is a formwork, it is not removed after being filled with concrete, and is used in a buried state. However, it is also possible to expect a reinforcing effect that prevents chipping of the sides and corners), and inside the area surrounded by this buried formwork, reinforcement consisting of standardized vertical members and horizontal members. It is known that a member is provided and concrete is poured into an embedded formwork together with these reinforcing members to be provided on a wall having a predetermined shape.

FIG. 3 is a perspective view showing a concrete example of a conventional precast concrete curtain wall. Here, 1 is a buried formwork, 2 is a reinforcing member, 2a is a vertical member, 2b is a horizontal member, and 3 is concrete.

In addition, including the manufacturing method, in the construction, when placing the formwork at a predetermined place and deploying inside the formwork, for example, some reinforcement members (vertical members and horizontal members) Bend both ends of the (member), insert this bent portion into a bolt that is simply fixed to the formwork, fix it with the embedded formwork and stat bolts, and assemble the vertical member and the horizontal member in a grid pattern. There have been proposed attachment means used to restrain the warp of the reinforcing member. (See Japanese Patent Application No. 3-335952, filed on Dec. 20, 1991, which is the applicant of this application)

[0005]

[Problems to be solved by the device]

 However, here as well, some modifications were devised regarding the assembly at the grid point position and the workability related to accuracy, which differed from the conventional configuration, and a new assembly structure including improved members was used. Has also been expected.

That is, it is an assembling structure in which the assembling of the members forming the lattice points is easier, and a firm fixation is obtained after the assembling.

The present invention has been made in view of the above-mentioned circumstances, and in addition to solving the above-mentioned problems, a precast structure in which a vertical member is provided with a horizontal member and a through hole for concrete to improve an assembling structure. It is intended to provide an assembly structure of a reinforcing member for a concrete curtain wall.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a reinforcing member that is assembled in a lattice shape by appropriately combining vertical members and horizontal members when mounting a reinforcing member disposed in an embedded formwork of a precast concrete curtain wall. In the assembly structure, one or more members having large rigidity selected from I-type steel, groove-type steel, chevron steel and H-shaped steel are used for the vertical members, and horizontal members are used at the body lattice points of the members. A hole through which concrete is inserted is provided, and flat steel or shaped steel having lower rigidity than the vertical member is used for the horizontal member, and a notch is formed from one end in the width direction to the opposite direction, and the vertical member is placed at the grid point position. At the same time as fitting, bend the end of the horizontal member in the longitudinal direction, engage the notch provided in this bent portion with the fixing bolt protruding on the inner surface of the formwork, and combine them in a grid shape, at the grid point position, Notch that straddles the lateral material The cross-sectional U-shaped fixing bracket having a part and is characterized in that it consists of the upper end of the vertical member by fitting-fixed.

[0009]

[Action]

 In the mounting structure of the present invention, the warp of the structure is restrained by assembling the vertical members and the horizontal members, which are the reinforcing members, in a grid pattern.

Further, by selecting a member having high rigidity as the vertical member and providing a hole in this body portion, the continuity of the concrete is ensured and the load burden is biased, so that the rigidity of other members is reduced. Enables material selection.

【Example】

 BEST MODE FOR CARRYING OUT THE INVENTION An optimum embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partial perspective view showing an assembly structure embodying the present invention. 2A and 2B are explanatory views of a fixing metal fitting, which is one of the constituent elements of the present invention. FIG. 2A is a plan view and FIG. 2B is a side view.

As shown in FIG. 1, for the vertical member (2a) which is the reinforcing member (2), one or more members having large rigidity selected from I-type steel, groove-type steel, angle-shaped steel and H-type steel are used. An oval hole (8) through which the horizontal member (2b) and concrete are inserted is provided at the lattice point position of this member (2a).

The horizontal member (2b) is a flat steel or a die steel having a rigidity lower than that of the vertical member, and the notches (4) are formed at lattice intervals from one end in the width direction to the opposite direction. Further, both longitudinal end portions of the lateral member (2b) are bent, and a notch portion (4) is formed in this plane from the opposite side of the notch direction.

At the time of combination, the embedded formwork (1) is placed on a plane, and the vertical members (2a) are arranged in parallel in a proper space (lattice space) so that the upper and lower surfaces of the vertical member (2a) are on the same plane. The transverse member (2b) is inserted through the hole (8) of the vertical member (2a) at a right angle to this and fitted toward the upper edge of the vertical member (2a) at the lattice point position.

On the other hand, the notch (4) provided in the bent portion at the longitudinal end of the lateral member (2b) is engaged with the fixing bolt (5) projecting on the inner surface of the form (1), and the nut is tightened with the nut. Bolt leg rod Tighten the screw part.

This constitutes a grating structure in which the upper surfaces of the horizontal members (2b) are aligned so that they are on the same plane. Therefore, here, the vertical member (2a) corresponds to the bearing bar and bears the main load.

Further, a fixing member (6) having a U-shaped cross section having a cutout portion (4 ′) straddling the horizontal member is fitted from one end (here, the upper edge) of the vertical member (2a) (by tap fitting). Good), fix the grid position. As shown in FIG. 2, it is preferable to use a fixture having a U-shaped cross section and provided with shift stoppers (7) at opposite positions on the sides of the fixture.

In this way, the precast concrete curtain wall structure immediately before the concrete is poured is prepared.

FIG. 3 is a perspective view showing a concrete example of a conventional precast concrete curtain wall, but the one having an assembling structure of the reinforcing member (2) according to the present invention is also similar in construction.

[0020]

[Effect of device]

 The present invention has the above-mentioned structure. According to this, the method of assembling the vertical and horizontal members, which are the reinforcing members, is improved, so that even a beginner can easily work, and the mold is better than the conventional example. The frame and the reinforcing member can be set accurately in a short time, and the grid point positions are firmly fixed, improving workability.
