Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for mounting an exterior wall formed by stacking exterior wall panel members and its mounting hardware, and provides an aesthetically pleasing exterior wall in which support columns and mounting hardware are not exposed on the outside. It is something that is created.

As one of the conventional external walls, when constructing an external wall by inserting and stacking concrete panels such as precast concrete plates into the grooves of supporting columns that extend in the longitudinal direction, the supporting columns are exposed on the outside. In addition, in order to eliminate gaps between the concrete panels and the concrete panels that are fitted into the grooves of the support pillars, and to prevent looseness, other members such as angle members must be used for installation. Therefore, there are drawbacks such as the installation is cumbersome and difficult, and it is difficult to eliminate backlash.

Therefore, in order to eliminate such conventional drawbacks, the present invention provides a mounting screw hole member or bolt member embedded near the side edge of the back side of the concrete panel, and allows bolts or nuts to be inserted through the mounting plate. The object of the present invention is to provide an exterior wall mounting method characterized by constructing an exterior wall by attaching concrete panels to support columns and its mounting hardware.

Other objects, features, and advantages of the invention will become apparent from the following detailed description of an embodiment illustrated in the accompanying drawings that utilizes panels, such as precast concrete plates.

1 to 3 of the drawings show a first embodiment of the exterior wall mounting method of the present invention.

As shown in the figure, the support columns 2 are made of section steel with an appropriate cross-sectional shape, such as H-section steel, and are installed at required intervals based on the span of the panels 4, such as precast concrete plates, to be attached. Ru.

Of course, this support column 2 can be made of not only H-shaped steel but also T-shaped steel.

The front side of the panel 4 is left as is, or has an appropriate pattern or color applied depending on the purpose of use, and the back side has screws as shown in Figure 3.4.5. An insert member 16' connected in advance by a cut U-shaped screw hole member 6, a bolt member 6', or a U-shaped bolt portion 6'' is embedded and fixed.

The threaded hole member 6 shown in FIG. 3 is made of a pipe member such as a suitable steel pipe in a U-shape, and female threads are cut in the pipes at both ends, and the bolt member 6' shown in FIG. The insert member 16' is made by bending a rod member into a U-shape, and threads are cut at both ends.The insert member 16' shown in FIG. 5 has a cross-sectional shape as shown in the figure, and is provided with a screw hole 17'.

Therefore, these U-shaped screw hole members 6 and bolt members 6
Alternatively, the insert member 16' is embedded in the back side of the panel 4 and fixed.

The panel 4, on which the screw hole member 6, bolt member 6' or insert member 16' is embedded and fixed on the back side, is attached to the flange portion 3 of the support column 2 with bolts 11 or nuts via the mounting plate 8. Alternatively, in the case of a prismatic column, it is attached to the prismatic column itself.

The mounting plate 8 has a rectangular shape as shown in FIGS. 1 and 2, and as shown in the figure, it is bent into a roughly lightning shape in order to obtain elasticity, and is provided with elongated holes 9 for one or more bolts. ing.

The positions of these long holes 9 are determined according to the screw hole members 6 or bolt members 6' provided on the back surface of the panel 4.

Therefore, in the mounting method of the present invention, the panel 4 is first set from below on the support columns 2 installed at a required interval corresponding to the span of the panel 4, and Screw hole member 6 embedded and fixed on the back side near the edge
Alternatively, a bent rectangular mounting plate 8 may be attached to the bolt member 6'.
The bolt 11 is inserted into the screw hole member 6 through the long hole 9 for the bolt.
The panel 4 is attached to the flange portion 3 of the support column 2 by screwing the bolt member 6' to the flange portion 3 of the support column 2.

The next panel is then stacked on top of this panel 4 and installed in the same manner.

Sets of stacked panels are then placed next to each other to construct an exterior wall.

It is more preferable that the upper and lower edges of the panels 4, which are attached to the support column 2 in a stacked manner as described above, are provided with concave and convex portions that fit into each other.

As described above, according to the present invention, even if there is a decrease in the installation accuracy of the support column, that is, a decrease in the accuracy of the panel installation interval due to the inclination of the support column or the uneven spacing between the support punches, there will be no problem. In addition, the panels can be installed in a continuous state with both side edges of the panels adjacent so that the support pillars are not visible from the outside, and bolts can be easily installed, allowing for easy installation of bolts through the mounting plate. The panel can be attached to the support pillar using bolts, which reduces installation costs and can be done in a short period of time.

Therefore, when used for general fences, external walls, or sound insulating walls on expressways, it is suitable for aesthetically pleasing appearance without visible support columns, can be constructed quickly in a short time, is easy to install, and can be constructed even in limited narrow spaces. A beautiful exterior wall can be obtained.

In addition, a more suitable outer wall can be obtained by using a panel with an appropriate pattern corresponding to the purpose of use, such as a stone wall pattern or a geometric pattern, on the surface.

In the embodiment shown in FIGS. 1 to 3, a U-shaped screw hole member 6 is embedded in the back side of the panel 4, but instead of such a screw hole member 60, as shown in FIG. It is also possible to use a U-shaped bolt member 6' with threads at both ends, or it is possible to use a U-shaped bolt member 6'' as shown in FIG. The provided insert member 16' can also be embedded and used.

In this way, if the screw hole members and bolt members are made in a U-shape, they will be connected in a U-shape, so that the screw hole members or bolt members can be easily and easily fixed when pouring concrete into a concrete panel. Two can be fixed at once.

In addition, there is a limit to the thickness of concrete panels, and screw hole members and bolt members do not have sufficient adhesion resistance under normal conditions, so special processing of reinforcing bars for anchors is required. This problem can be solved by making the screw hole member or bolt member U-shaped and connecting the two members to increase the resistance to adhesion, thereby eliminating the need for special processing for the anchor.

Furthermore, the reinforcing bars for concrete panels are made of rice cake net-shaped reinforcement that is welded in the factory, and the concrete is passed through the inside of the U-shaped screw hole member or the U-shaped bolt member. Casting has advantages such as being able to prevent it from falling off in the event of damage.

In addition, although the above description uses panels such as precast concrete boards as exterior wall members, it is of course possible to use any other hollow or solid metal plates, synthetic resin boards, asbestos cement boards, etc. It is.
