DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing member structure of a lightweight cellular concrete panel, and more particularly to a reinforcing member structure suitable for a corner panel.

[0002]

2. Description of the Related Art A required building is often constructed by using so-called precast concrete panels for outer walls. In this case, as a configuration of a corner portion of a building, a corner panel formed in advance at a substantially right angle or the like in accordance with the corner shape may be used. Such a corner panel is used by connecting an adjacent flat wall panel and its opening to each other.

[0003] Reinforcing materials are embedded in such precast concrete panels in order to resist bending force or the like applied to the panels. Generally, a so-called mesh bar is used for the reinforcing bar structure of the reinforcing member so as to be able to cope with any bending direction, and the shape of the bar is larger than that of the mesh bar for the purpose of reinforcement depending on panel dimensions and the like. Reinforcing bars such as angle members may be provided by welding to the mesh bars through the longitudinal direction of the panel. In order to attach the corner panel to the building frame, usually, a nut or the like is attached to a reinforcing member made of the above-mentioned mesh bar or reinforcing bar at a position facing the end of the panel.

[0004] The corner panel is formed from lightweight cellular concrete for reasons such as convenience of handling. Since the lightweight cellular concrete panel has a porous structure, it can be said that it is fragile and has lower rigidity than ordinary concrete panels.However, since the panel itself is lightweight and the load due to its own weight is reduced, it has sufficient performance as a building material depending on the application. There is a plan to use it taking advantage of its lightness. For example, in the case of a corner panel having a height of about 2.5 m over one floor like a house, it is not always necessary to use reinforcing bars. Nevertheless,
In the past, the reinforcement of the corner panels was designed by considering the extra safety factor because of the weakness of lightweight cellular concrete, etc., and the lightness characteristic of lightweight cellular concrete is fully utilized. Did not.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above situation, and can reduce the weight of a panel without deteriorating the mounting strength and rigidity of the panel, and is excellent in workability and practicality. It is intended to provide an economical lightweight cellular concrete corner panel reinforcement arrangement.

[0006]

That is, the present invention provides:
In a reinforcement structure of a lightweight cellular concrete corner panel integrally bent and formed in alignment with the corner angle of the building over at least one floor height, the bent panel is appropriately parallel to the transverse direction of each of the two surfaces of the panel. Short reinforcing bars arranged at intervals and crossed at the end side located at the corner side of the panel, and at least at the crossing portion, span the short reinforcing bars parallel to the longitudinal direction of the panel and connect the short reinforcing bars in parallel. A through-bar that has been welded to at least one bar of a short bar or a through bar located near both ends in the longitudinal direction of the panel, and an angle-shaped nut support member disposed parallel to the panel longitudinal direction, It is characterized by comprising a mounting nut welded to the nut support member and having one end opened on the panel surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of an example of a reinforcing bar structure of the present invention, in which an intermediate portion thereof is omitted. FIG. 2 is a perspective view of a main portion showing an example of a lightweight cellular concrete corner panel in which the reinforcing member is embedded. 3 is a plan sectional view of a corner panel.

The reinforcing arrangement according to the present invention comprises a short reinforcing bar, a penetrating reinforcing bar, a nut support member and a mounting nut, and is aligned with the corner angle of the building over at least one floor height as shown by a chain line in FIG. It is used by being embedded in a corner panel C made of lightweight cellular concrete which is integrally bent and formed, and is used to reinforce the corner panel C and to connect and fix the corner panel C with an adjacent wall panel W or a building frame (not shown). . FIG. 1 shows an example of the reinforcing member.
In the drawing, reference numeral 10 denotes a reinforcing member, 11 denotes a short reinforcing bar, 12 denotes a through reinforcing bar, 13 denotes a nut support member, and 14 denotes a mounting nut. In FIG. 2, illustration of the nut support member and the mounting nut is omitted.

As shown in FIG. 1 and FIG.
1 is the lateral direction C1, C of each of the corner panels C
1 and in the longitudinal direction C2 of the corner panel C
At appropriate intervals. The length of the short reinforcing bar 11 is determined on two sides of the corner panel C (Ca, C shown in FIG. 3).
The short reinforcing bars 11, 11 respectively arranged in b) have such a length as to intersect as shown in FIG. 2 at the end on the corner C3 side of the corner panel. In addition, short reinforcing bar 11
There is no particular limitation on the number and arrangement intervals thereof, and they are appropriately set according to the size of the panel.

[0010] The through-bar 12 is mainly for maintaining a parallel arrangement interval of the crossed short bars 11, 11, and at least an intersection 15 of the short bars 11, 11.
In this case, the short reinforcing bars 11 are bridged between the short reinforcing bars 11 in parallel with the longitudinal direction C2 of the corner panel C and are integrally fixed by welding or the like, thereby connecting the short reinforcing bars 11 in parallel. Depending on the length of the short direction C1 of the corner panel C and the dimension of the long direction C2, the number of the through reinforcing bars 12 can be appropriately provided not only at the intersection 15 but also at an appropriate position of the short reinforcing bar 11. In this embodiment, two through-bars 12 are arranged so as to sandwich the intersection 15 from both sides.

The nut support member 13 has two sides 13a,
13b is formed in an angle shape forming a substantially L-shaped cross section, and one side 13a is at least one of the short reinforcing bar 11a or the through reinforcing bars 12, 12 located near both ends in the longitudinal direction C2 of the corner panel C. , And a mounting nut 14 is welded to the other side 13b. Since the nut support member 13 has an angle shape, it has high rigidity, reinforces the end of the reinforcing member, and holds the mounting nut 14 at a correct position. The nut support member 13 of the present embodiment includes a plurality of short reinforcing bars 11a as shown in FIG.
Welded to.

The length of the nut support member 13 may be such that a plurality of short reinforcing bars 11a near both ends in the longitudinal direction C2 are welded. By arranging the nut support members 13 in the vicinity of both ends in the longitudinal direction C2 of the corner panel C and setting the nut support member 13 shorter than the conventional bar arrangement structure, the weight of the corner panel C due to the embedding of the reinforcement member is provided. The increase is reduced and workability during panel construction is ensured.
In particular, it is very convenient because effective strength can be imparted without impairing the lightness of the lightweight cellular concrete. Further, the nut support member 13 may be economical because it may be short, and may be any one having an angle shape as shown in the figure. And can reuse resources.

Each side 13 of the nut support member 13
There is no particular limitation on the widths of a and 13b. One side 13a and the short reinforcing bar 11 can be securely welded to each other, and the other side 13b and the mounting nut 14 can be reliably welded and fixed. The width is completely embedded in the corner panel C.

As shown in FIG. 2, for example, the mounting nut 14 is for fixing a metal fitting 18 for connecting the corner panel C and the wall panel W with a bolt 17, and has a bolt screw opening 14b at one end (FIG. 1). 3 is welded and fixed to the other side 13b of the nut support member 13 at one side surface 14a so as to open at the surface of the corner panel C.

In this embodiment, the mounting nut 14 is
As shown in FIG. 1, the nut C is welded to the nut support member 13 so as to open at the upper and lower surfaces of the panel C.
When the mounting is performed on the inner surface of the panel C (not shown), the mounting nut 14 is oriented along a direction perpendicular to the inner and outer surfaces of the panel C, and the bolt screw hole 14b is connected to the panel C.
Is welded to the nut support member 13 so as to open on the inner surface of the nut.

When the corner panel C is formed, the reinforcing member 10 having the above-mentioned structure is arranged in advance in the form of the corner panel C, and is integrally embedded in the panel by casting a lightweight cellular concrete slurry.

[0017]

As shown and described above, the reinforcing arrangement of the lightweight cellular concrete corner panel of the present invention is as follows.
It consists of short reinforcing bars, through reinforcing bars, angle-shaped nut support members and mounting nuts provided near both ends of the panel in the longitudinal direction, and the main reinforcing bars are reinforcing bars. Thus, it is possible to obtain sufficient panel strength and to obtain good workability while making the lightweight cellular concrete corner panel heavy without taking advantage of the lightweight characteristic which is an excellent feature of lightweight cellular concrete.

Further, according to the reinforcing arrangement of the present invention, waste materials and scraps generated when processing other steel members can be used as nut support members, so that resources can be recycled and cost can be greatly reduced. Can contribute.
