Regarding LC wall structure. More specifically, it is not necessary to provide L-shaped receiving angles on both sides and the upper side of the ALC wall panel, and the L-shaped receiving angle on the upper side of the ALC wall panel, hook bolts, etc. stand up and project to the inside of the ALC wall panel. The present invention relates to a rising ALC wall structure with a handrail such as a corridor, a staircase or a balcony, a veranda, and a parapet.

[0002]

2. Description of the Related Art Conventionally, as a structure of a rising ALC wall with a handrail such as a corridor, stairs or balcony, veranda, parapet, etc., a structure as shown in FIG. 7 is known. That is, an L-shaped receiving angle 91 that receives the lower fore edge 90 of the ALC panel P, an L-shaped receiving angle 92 that supports the upper portion of the ALC panel P, and an L-shaped angle 93 on the side surface of the panel that connects them. The ALC panel P is supported. Further, countersunk holes and bolt holes are formed in the upper part and the lower part of the ALC panel P, and the washers and the hook bolts 94 mounted in these holes are used to fix the holes. Welded and fixed to the L-shaped receiving angle 91 and the upper L-shaped receiving angle 92,
The C panel P is fixed.

The pillar 95 of the handrail H is fixed to the upper surface of the L-shaped receiving angle 92 that supports the upper portion of the ALC panel P by welding or bolting. This structure is ALC
Support the upper and lower ends of the wall with L-shaped receiving angles,
Moreover, since the handrail pillar is directly fixed to the L-shaped receiving angle, the force applied to the handrail H is not applied to the ALC panel P.

[0004]

However, in the conventional standing ALC wall structure with handrails for fixing the handrail post as described above, L-shaped receiving angles must be provided on both side surfaces of the ALC wall panel and the upper and lower portions thereof. Not only do they have to be installed, but the upper L-shaped receiving angle and hook bolts also stand up.
Since it projects inside the C wall panel, it is not preferable in appearance. In order to solve this problem, it was necessary to attach a molding board or the like to the back surface of the panel to cover the L-shaped angles on both side surfaces of the panel. Therefore, there are problems that the number of members for supporting the panel is further increased, the cost is increased, and the mounting work is troublesome.

Therefore, an object of the present invention is that it is not necessary to provide an L-shaped receiving angle on both side surfaces and an upper portion of the ALC wall panel, and the L-shaped receiving angle and the hook bolts on the upper portion are raised to the inside of the ALC wall panel. In addition, it has a structure that does not need to be protruded, and that it is not necessary to attach a molding board or the like to the back surface of the ALC wall panel to cover the L-shaped angles on both sides of the panel, and to mount it with fewer supporting members. (EN) To provide a rising ALC wall structure with a handrail, which is low in cost because it can be done, and which does not require a lot of work for attaching the handrail pillar.

[0006]

In order to solve the above problems, the present invention has the following constitution. The side edge surfaces of a plurality of ALC panels are butted against each other to form an ALC wall, and the lower and middle portions of the ALC panels are anchor portions embedded in the ALC panels and mounting fittings that engage with the anchor portions. The mortar is attached to the skeleton through the mortar, and the mortar is poured into the voids in the joints formed by the side edge faces of the ALC panel butting against each other, and the load applied to the mortar on one sheet of the ALC panel. Is embedded in the mortar in the joint from above the ALC panel, and the embedded member made of steel bar such as joint rebar is embedded in the adjacent ALC panel. A locking metal fitting is provided on the upper part, and a steel plate is laid on the upper edge face of the ALC panel through the locking metal fitting.
The rising ALC wall structure with handrails is characterized in that the handrail pillars are fixed to the steel plate while being fixed.

The operation and effect of the present invention will be described below. In the present invention, the ALC panel is attached to the skeleton at the center in the width direction and at two places, the lower part and the middle part, and the steel plate is laid / fixed on the upper edge face of the panel via the locking metal fittings. In combination with the structure described above, sufficient mounting strength is obtained, and it becomes unnecessary to provide L-shaped receiving angles on both side surfaces and the upper portion of the ALC wall panel. Further, it is not necessary to attach a molding board or the like to the back surface of the ALC wall panel to cover the L-shaped angles on both side surfaces of the panel.

Therefore, since the mounting can be performed with a smaller number of supporting members, the cost is reduced and the mounting work is also reduced. Further, since the steel material such as the upper L-shaped receiving angle does not project inside the rising ALC wall panel, the appearance of the upper surface of the panel is not particularly spoiled. Further, since the handrail pillar is provided on the upper edge face of the ALC panel, the load applied to the handrail can be transmitted to the panel without difficulty and the entire wall can support the load.

In the present invention, as a structure in which a steel plate is laid and fixed on the upper edge of the panel, a locking metal fitting is provided at the upper end of the embedding member embedded in the joint of the ALC panel. It is preferable that the steel plate is a bolt, and a through hole is formed in the steel plate, and the steel plate is laid and fixed by the bolt penetrating the through hole and a nut screwed with the bolt.

As described above, when the bolt provided at the upper end of the embedding member embedded in the joint is used as the locking metal fitting, it is not necessary to make a hole or the like in the ALC panel, and therefore the work can be omitted. it can. Also, there is no reduction in strength due to the formation of holes or the like. In addition, if a through hole is made in the steel plate in advance, the AL
The steel material can be fixed on the upper fore surface of the ALC panel simply by laying a steel plate on the upper fore surface of the C panel and screwing a nut onto the bolt from above. As a result, the cost can be reduced because the mounting can be performed with a smaller number of members, and welding is not required on the mounting work surface, which further reduces the labor.

Further, in the second aspect of the present invention, the embedding member is a steel bar in which a bolt is provided at the upper end and at least one plate-like member is arranged at the lower end so that the surface is oriented in the horizontal direction. Is desirable.

The embedding member functions as follows. The mortar is poured into the cylindrical void in the joint formed by the side edge faces of the ALC panel on which the semi-cylindrical recess is formed, but the embedding member is inserted into this mortar, and the bolt is installed. The upper end part is projected. At this time, since the lower end portion of the steel bar is a plate-shaped member, even if the mortar has a considerably high viscosity, it can be easily inserted without requiring a great force.

After that, since the viscosity of mortar is usually high,
If left alone without any support, the embedding member is fixed as the mortar solidifies. Then, a steel plate is laid on the upper small surface of the ALC panel, a nut is screwed onto the bolt from above, and the plate-shaped member at the lower end of the steel bar prevents the steel bar from rotating when tightening the nut. Acts like. Therefore, the embedded member can tighten the nut more strongly than usual. Further, the shoulder portion of the plate member also plays a role of preventing the steel material from coming off.

Further, in the present invention, the anchor portion further embedded in the ALC panel is composed of a long L-shaped plate and a nut fixed to at least one central portion thereof, and the length of the L-shaped plate is increased. Has a length of 1/3 or more of the width of the ALC panel,
Since the force does not concentrate only on the panel body around the nut, the panel mounting strength is greatly improved.

Further, in the above invention, the mounting strength is further improved by adopting the following structure in which the mounting fittings are fixed. That is, as a mounting bracket, a mounting plate provided with a bolt insertion portion, a protruding piece formed by extending the upper portion thereof, a rib piece formed by bending both side edges of the mounting plate, and a rib piece thereof. A hanging rib piece formed by hanging further downward is used, and the hanging rib piece is welded and fixed to the standing piece of the body.

According to such a mounting bracket, both side edges of the mounting bracket are bent to form rib pieces, and further, hanging rib pieces are formed so as to hang downward from the rib pieces. The yield strength of the mounting bracket is greatly improved. Further, it is possible to prevent the upper portion of the mounting member from being embedded in the panel, and it is possible to improve the proof stress against the pressing force of the panel.

[0017]

EXAMPLE An example in which the present invention is applied to a veranda will be described below with reference to FIGS. As shown in FIG. 1, a plurality of ALC panels P are butted against each other at the side edge faces 22 to form a rising ALC wall W. It is preferable that the panel P used for them has a height of 500 to 2000 mm, a width of 300 to 600 mm, and a thickness of 80 to 150 mm.

Each ALC panel P is provided with a beam 24, an L-shaped angle 23, and an anchor portion 9 and 10 embedded in a central position in the lateral direction, and a beam 24, an L-shaped angle 23,
It is attached to a building body 4 composed of 25 and the like. The mounting positions are located at two positions near the lower part of the panel and the intermediate part in the vertical direction and at the center part in the lateral width direction of the panel.

The position of the intermediate anchor portion 9 is separated from the lower anchor portion 10 by 300 mm or more. In addition, the distance from that position to the panel upper edge 11 is 1 at maximum.
It is preferably 500 mm or less. In addition, the beam 2 of the frame 4 to which the rising ALC wall W is attached in this way
An ALC panel for the floor or the like (not shown) is laid on the upper surface of 4. The anchor portions 9 and 10 embedded in the ALC panel P are, as shown in FIG. 3, a long L-shaped steel 19 having a length of 3/4 of the width of the ALC panel P and a central portion thereof. It consists of one nut 20 fixedly attached.

An L-shaped angle 23 is welded and fixed to the beam 24 or the like at the position of the anchor portion 9 in the middle portion so that the back surface of the vertical flange portion, which is the standing piece portion 17 of the frame, contacts the panel surface. It is provided in. Further, the lower end surface of the panel is placed on the L-shaped angle 25, and the inner side surface of the vertical flange portion of the L-shaped angle 25, which is also the standing piece portion 34 of the frame, is installed so as to abut the panel inner surface. The mounting brackets 8 described below are fixed to the standing piece portions 17 and 34 of the L-shaped angles 23 and 25 by the following means in correspondence with the positions of the anchor portions 9 and 10 near the lower portion of the panel and the middle portion. Has been done.

As shown in FIG. 2, the mounting member 8 has a mounting plate 13 provided with a bolt insertion portion 18, a projecting piece 14 formed by extending the upper portion thereof, and the mounting plate 1.
Rib pieces 15 formed by bending both side edges of 3;
The rib piece 15 is composed of a hanging rib piece 16 formed by hanging further downward. Further, the thickness of the mounting plate 13 is substantially equal to the thickness of the L-shaped angles 23 and 25, and the rib piece 15 is formed by bending both side edges of the mounting plate 13, and the hanging rib piece 16 is downward from the rib piece 15. Since it is formed by hanging on the
3 has a step difference from the surface by the thickness of the plate.

Therefore, if the step is engaged with the vertical flange portion of the L-shaped angle 23, 25 which is the standing piece portion 17, 34 of the skeleton and the portion is welded and fixed, the surface of the mounting plate 13 and the vertical flange portion. The parts are almost on the same plane,
There is no step or gap when a panel is applied to it. Further, the presence of the projecting piece 14 allows the mounting fitting 8 to have a wide surface for pushing the ALC panel P, and the projecting piece 14 is a plate-shaped body without the rib pieces 15 provided on both side edges. Therefore, since the ALC panel P is pushed while flexing slightly, the mounting plate can be supported without being dented into the panel. As a result, the proof stress against the pressing force of the panel can be improved.

In the joint portion 21 of the ALC panel P, a joint rebar is provided and embedded as the embedding member 12, and a bolt is engraved on the upper end portion of the joint rebar to form the locking fitting 3. 5 are provided. On the other hand, a steel plate 2 having a through hole 6 formed therein is laid on the upper edge surface 11 of the ALC panel P, a bolt 5 is penetrated through the through hole 6, and a nut 7 is screwed into the bolt 5. The steel plate 2 is fixed. The handrail post 1 is welded and fixed to the steel plate 2, and a large number of horizontal bars are inserted into the handrail post 1 to form the handrail H. Further, the method of fixing the handrail pillar 1 to the steel plate 2 is not limited to welding, but may be fixed by bolts or the like, and various other methods are applied.

Next, a method of assembling the rising ALC wall structure with handrail will be described. As shown in FIG. 4, first, the mortar M is poured into the cylindrical void portion in the joint portion 21 formed by the side edge surfaces 22 of the ALC panel P having the semi-cylindrical recesses 27 formed in contact with each other. , Cure the mortar M. As a result, the joint portion 21 of the ALC panel P becomes strong, and the adjacent ALC panels P are integrated. In this way, the mortar M also plays the role of distributing the load applied to one panel to the adjacent panels.

At the time of pouring the mortar M, an embedding member 12 having a bolt 5 serving as a locking fitting 3 formed at the upper end is prepared in advance. Then, the embedding member 12 is embedded and fixed in the mortar M at the upper part in the joint portion 21 between the ALC panels P so that the locking metal fitting 3 protrudes from the upper edge surface 11 of the ALC panel P.

Next, the steel plate 2 is locked to the projecting locking metal fitting 3 and is laid and fixed on the upper edge surface 11 of the ALC panel P, and the handrail post 1 is fixed to the steel plate 2. More specifically, a steel plate 2 in which a through hole 6 is separately provided is prepared, and a bolt 5 (locking metal fitting 3) is passed through the through hole 6 of the steel plate. Then, the nut 7 is screwed into the bolt 5 from above the steel plate 2 to lay and fix the steel plate 2 on the upper edge surface 11 of the ALC panel P.

If such a bolt 5 is used as the locking fitting 3 and the steel plate 2 is laid and fixed by using the nut 7, the cost can be further reduced because the mounting can be performed with a smaller number of members. Also, the installation work becomes easy.
Further, even if the panels are shaken, the steel plate 2 is firmly attached to the upper edge surface 11 of the ALC panel P and is not lifted at all, so that the connection between the panels becomes stronger,
Therefore, a more robust rising ALC wall structure with a handrail is obtained. In addition, since the mortar M solidifies to several times the strength of the ALC panel P after solidification, the embedding member 12 includes the handrail H and the steel plate 2.
It will be a stronger anchor.

Next, another embodiment of the present invention will be described. As shown in FIG. 5, the decoration grid 2 is provided on the balcony or the like.
In order to attach 8 etc., if a short panel is used as a part of the rising ALC wall panel,
It is not possible to connect the panels with the mortar M by forming the semi-cylindrical concave line 27 on the side edge 22 of the ALC panel P as shown in FIG. Therefore, when the embedding member 12 is embedded and the locking metal fitting 3 cannot be projected from the embedding member 12, when fixing the steel plate 2 to the ALC panel edge faces 11 and 22,
Alternatively, when the frame 29 or the like of the decorative grid 28 is freely attached to the front face of the ALC panel, the embedding member 12 is replaced by the following member instead of the joint rebar as in the above embodiment, and the steel plate 2 or Attach the frame 29 and the like.

Then, a hole 32 into which the locking rod 31 and the welding plate 30 are fitted is provided at an arbitrary position on the ALC panel edge faces 11 and 22, and the embedding member 12 is inserted into this hole 32, and the steel plate 2 or The frame 29 and the like are locked and fixed by means such as welding. By doing so, the steel plate 2, the frame 29, and the like can be attached at free positions of the ALC panel edge faces 11 and 22. The embedding member 12 having the above structure may be applied to the joint portion 21 in the above embodiment.

The mode of the embedding member and the locking metal fittings for locking the embedding member according to the present invention is not limited to the above embodiment, and the embedding member is a cylindrical body (not shown) having the size of the joint portion. Etc. can be applied. In addition, a protrusion 33 for preventing slipping off may be provided at the tip of the locking rod 31.

Further, as described above, the embedding member 12 is a steel bar 35 having a bolt 5 at the upper end and at least one plate-like member 26 arranged at the lower end so that the surface is oriented horizontally. 7 can be tightened more strongly,
Further, there is an advantage that the steel bar 35 becomes more difficult to come off. In this embodiment, as shown in FIG. 6A, the embedding member 12 embedded in the joint portion 21 is provided with the bolt 5 at the upper end portion of the steel bar 35 such as the joint rebar described above, and the lower end portion thereof. The plate-like member 26 is in the form of a battledore. This form can be easily manufactured by pressing the lower end portion of the steel bar 35. Further, as shown in FIG. 6B, the embedding member 12 is provided with bolts 5 at the upper end of the steel bar 35, and radially from the axis 36 of the steel bar 35 at the lower end thereof as in the mounting state of arrow feathers. The plate-shaped member 26 may be disposed in the.

[0032]

As described above, the rising ALC wall structure with a handrail according to the present invention has L-shapes on both side surfaces and an upper portion of the ALC wall panel.
Since it is not necessary to provide a letter-shaped receiving angle, it is possible to reduce the cost and the mounting work. Further, the L-shaped receiving angles and hook bolts on both side surfaces and the upper portion do not stand up and project inside the ALC wall panel. Therefore, the appearance is not impaired, and it is not necessary to attach a molding board or the like to the back surface of the ALC wall panel to cover the L-shaped angles on both side surfaces of the panel. Furthermore, by using the embedding member of claim 3, the anchor of claim 4, and the mounting bracket of claim 5,
The mounting strength becomes even stronger.
