Description

[Detailed description of the invention] This invention relates to a panel mounting structure for renovating the external wall surface of an existing building.

Conventionally, when renovating the exterior walls of existing buildings, methods such as laying tiles have been generally implemented, but there are drawbacks such as the construction is not easy, the construction costs are high, and the construction period is long.

Therefore, the applicants are developing a method of renovating the building's exterior wall by covering it with metal panels.
The purpose of this invention is to propose a panel mounting structure that allows panels to be easily mounted on an external wall surface with a good finish and appearance using this construction method, and that is also easy to dismantle and partially renovate.

This invention will be explained below in accordance with the construction procedure based on the embodiment shown in the drawings. First, anchor hardware 2 is fixed to the exterior wall surface 1 of an existing building so as to be arranged in a series at predetermined intervals in the vertical and horizontal directions. do.

This anchor hardware 2 is formed into a T-shaped cross section by vertically welding a vertically elongated steel joint plate 2b to the surface of a steel substrate 2a, and is pre-filled in elongated holes 3 provided in at least two places on the steel substrate 2a. It is fixed by passing a fixing bolt 4 buried and fixed into the outer wall surface 1 and tightening it with a nut 5. In this case, a part of the outer wall surface 1 on which the anchor hardware 2 is attached is scraped off and the mounting surface is properly modified with mortar so that the mounting height of each anchor hardware 2 and the vertical direction of the joint plate 2b are exactly the same. Adjust as follows.

After fixing the anchor hardware 2 in this way,
Joint plate 2b of vertically adjacent anchor hardware 2, 2
A furring 6 made of channel steel or the like is fixed with bolts 7, and the furring 6 is successively fixed in the vertical direction of the outer wall surface 1 in the same manner.

Next, horizontally long outer wall panels 7 are sequentially and continuously attached to the left and right side-by-side furrings 6 from the bottom to the top of the outer wall surface.

As this exterior wall panel 7, a lightweight and highly rigid corrugated plate such as a deck plate used as a formwork for creating floor slag is used, and on the back side, vertical beams 8 for reinforcing and fixing, such as angle steel, are pre-installed at the factory. Multiple pieces are welded and fixed at predetermined intervals on the left and right, and this vertical rail 8
A joining metal fitting 9 such as an angle metal fitting having a horizontally protruding tip is welded and fixed to the side surface of the upper end. moreover,
A hook-shaped locking piece 10 with an upwardly projecting tip is welded and fixed to a predetermined position on the slope of the corrugated plate at the lower end of the back surface of the outer wall panel 7.

On the other hand, on the side surface of the flange 6 to which the outer wall panel 7 is attached, a joining metal fitting 11 to which the joining metal fitting 9 of the outer wall panel 7 is overlapped and joined is fixed in a predetermined position with bolts, and furthermore, on the front side, the joining metal fitting 9 of the outer wall panel 7 is attached. Stopper 10
A hook-shaped locking piece 12 with a downwardly protruding tip that receives and locks the locking piece 12 is fixed by welding, and the locking piece 12
A vibration isolating material 13 made of neoprene rubber or the like is attached to the front surface of the flange 6 opposite to the back surface of the tip end thereof to cushion the locking piece 10 engaged in the locking piece 12.

When installing the outer wall panel 7, the lower part of the locking piece 10 is engaged between the locking piece 12 of the rim and the vibration isolating material 13 to lock the lower part, and then the joining hardware 9 of the panel 7 is attached. are stacked on the joint metal fittings 11 of the furring 6 and fixed to each other with bolts 14. Then, the construction is carried out successively on the left and right sides using the same process, and then the outer wall panels 7 are successively attached above. In this case, the upper and lower outer wall panels are continuously integrated by overlapping their opposing upper and lower ends as shown in the figure.

By performing the installation work of the outer wall panels 7 in this way, it is possible to perform the bolt tightening work of the joining metal fittings 9 and 11 in the space above each panel 7,
The outer surface of the panel can be finished neatly without any unsightly parts such as bolts being exposed.

On the other hand, a small gap is maintained between the joints T between the outer wall panels 7, which are arranged in a row in the horizontal direction, and the joints T are in the same position in the upper and lower outer wall panels 7, so that they are aligned in a straight line in the vertical direction. Continuously. Then, in order to prevent rainwater etc. from entering through this joint part T, rain protection construction is performed.

That is, a groove-shaped downpipe 16 is fixed in advance to the rim 6 in the vicinity of the joint part T via a support arm 15 in a series from above and below, thereby surrounding the inside of the joint part T. The side wall of this downspout 16 is formed with unevenness that is approximately the same as the unevenness of the outer wall panel 7, so that it closely engages with the back surface of the outer wall panel 7, so that wind and rain do not blow into the inside even in strong wind and rain. Make it.

As described above, the installation of the exterior wall panels 7 is carried out continuously from the lower end to the upper end of the exterior wall surface 1, but due to the need to fix the scaffolding during construction and the need to be able to remove repaired parts after construction, Attach the curtain plate 17 to. Channel steel is used as the curtain plate 17, and its bottom surface is fixed with bolts 20 to a bracket 19 fixed with bolts 18 to a joint plate 2b of anchor hardware 2 arranged in series in the horizontal direction. Note that, similarly to the joint T of the outer wall panel 7, the joint between the left and right curtain plates 17, 17 is connected to the joint T of the outer wall panel 7 to prevent rain from rain by a downspout 16.

The curtain plate 17 is also fixed to the upper end of the outer wall surface 1, and a roof plate is attached above between the curtain plate 17 and the outer wall. Further, an opening is provided in front of the window of the existing building, and a new window frame is installed between the edge of the outer wall panel 7 around this opening and the existing window frame.

As described above, according to this invention, the exterior wall panel is attached to the rim that is fixed to the anchor metal fittings fixed to the exterior wall surface, so it is easy to construct, the material cost is low, and the construction can be done economically. The construction period can be shortened because construction can be carried out efficiently.

Then, in the outer wall panel, the locking piece attached to the lower end of the back surface of the panel is engaged and supported by the locking piece attached to the rim, and the joining hardware attached to the upper end of the back surface of the panel and the joining hardware attached to the rim are connected. Since it is fastened with bolts, there are no bolts or other parts exposed on the outside of the panel, resulting in a good-looking finish.
Since the bolt tightening work is performed in a space at the upper end of the panel where there are no obstructions, the installation work can be done efficiently in a comfortable position, and the panel can be easily dismantled and repaired partially.
