Abstract

PURPOSE:To improve the efficiency of work by removing a balcony cantilever from a reinforcing column, and by fitting the rear end of an extending reinforcing beam, on the fitting section of a rest for the reinforcing column balcony cantilever removed from. CONSTITUTION:A balcony cantilever 4 is removed from the fitting section 6 of a reinforcing column 3, and on the fitting section 6 of a rest for the balcony cantilever 4 of the reinforcing column 3 removed from, the rear end section of an extending reinforcing beam 7 is fitted with a bolt 9. After that, at the lower end section of the fitting section 6 set on the external surface of the reinforcing column 3, a bearing salient section 10 is saliently set, and in a state that the rear end section of the extending reinforcing beam 7 is mounted on the bearing salient section 10, the bolt 9 is inserted through the hole 12 of a fixing plate 11 and is spirally fitted on the screw hole 13 of the fitting section 6. After that, the front end section of the reinforcing beam 7 is placed between the new external wall panels 14 of an extension section 8 and is fitted on the reinforcing beam fitting section 16 of a connecting metal fittings 15 with a bolt 17. Then, on the extending reinforcing beam 7, the roof panel of the extension section 8 is fitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for removing a balcony in a building using the panel construction method and adding an extension to the area where the balcony has been provided.

[Conventional technology] In buildings using conventional panel construction methods, pillars are basically not used, and wall panels are connected to each other and wall panels and floor panels are connected via connecting fittings, and balconies are formed. In the construction, the rear end of the balcony cantilever was attached to this connecting fitting.

[Problems to be Solved by the Invention] When attempting to extend a building using the wall panel construction method described above, it is necessary to form a new frame for the extension, but in this case, However, there is a problem in that it is necessary to form a frame body, which makes the work complicated.

The present invention was devised in view of the problems of the conventional examples described above, and its purpose is to easily install reinforcing beams for extensions when removing balconies and adding to buildings using panel construction methods. The objective is to provide an extension method that can be installed on the wall and simplifies the extension work.

[Means for Solving the Problems] The extension method of the present invention provides a reinforcement method between the exterior wall panels 1 when forming a balcony 2 facing forward along a plurality of exterior wall panels 1 in a building 5 using the panel construction method. When constructing an extension by removing the balcony 2 of an existing building 5 in which the pillar 3 was erected and the rear end of the balcony cantilever 4 was fixed to the reinforcing pillar 3, the balcony cantilever 4 was fixed to the reinforcing pillar 3. The feature is that the rear end of the reinforcing beam 7 for extension is attached to the part 6 after removing the balcony cantilever 4 from the reinforcing column 3.

[Function] By providing the reinforcing columns 3 in the building 5 using the panel construction method, the cantilever beam 4 for the balcony can be
is removed from the reinforcing column 3, and when the balcony cantilever 4 of the reinforcing column 3 is removed, the rear end of the reinforcing beam 7 for the extension is attached to the part 6. It is now easy to install.

[Embodiments] The present invention will now be described in detail based on embodiments shown in the accompanying drawings.

As shown in FIGS. 1(a) and 1(b), an existing building 5 using the panel construction method having a balcony 2 is expanded by removing the balcony 2 and forming an extension part 8. In the present invention, the panel construction method building 5 to be expanded is
is constructed by connecting the exterior wall panels 1 to each other, the floor panels to each other, and the exterior wall panels 1 and the floor panel using connecting fittings, but in this case, a balcony 2 is formed facing forward along a plurality of exterior wall panels 1. In order to do this, a reinforcing column 3 is erected between the outer wall panels 1, and in the part 6 of the reinforcing column 3, the rear end of the balcony cantilever 4 is attached to the outer surface of the reinforcing column 3. is fixed with bolts.

Therefore, when building an extension, as shown in Figure 2 (a), it is necessary to attach the reinforcing column 3 to the balcony cantilever 4 at the 6th section.
Then, as shown in Fig. 2(b), the part 6 of the reinforcing column 3 where the balcony cantilever 4 has been removed is attached.
The rear end of the reinforcing beam 7 for the extension is attached to the rear end of the structure with bolts 9. Here, the mounting portion 6 provided on the outer surface of the reinforcing column 3 has a protrusion 10 protruding from the lower end thereof, and this receiver is attached to the protrusion 10 behind the reinforcing beam 7 for extension. The bolt 9 is inserted into the hole 12 of the fixing plate 11 at the rear end of the reinforcing beam 7 with the end placed on the reinforcing beam 7, and the bolt 9 is screwed into the screw hole 13 of the part 6. The front end of the reinforcement beam 7 for extension installed in this way is interposed between the newly installed outer wall panels 14 of the extension part 8, and the reinforcement beam attachment part 16 of the connecting fitting 15 that connects the newly installed outer wall panels 14 is attached to the part 16. It is attached by bolts 17 to. Then, the roof panel of the extension portion 8 is attached to the reinforcement beam 7 for extension.

[Effect of the invention] In the present invention, when forming a balcony facing forward along a plurality of exterior wall panels in a building using the panel construction method as described above, reinforcing columns are erected between the exterior wall panels and reinforcement When removing and expanding the balcony of an existing building where the rear end of the balcony cantilever was fixed to the pillar, the balcony cantilever was removed from the reinforcement pillar, and the balcony cantilever was fixed to the reinforcement pillar. Since the rear end of the reinforcing beam for the extension will be attached to the part where it was removed, we will use the reinforcing column installed in the building using the wall panel construction method to attach and support the cantilever beam for the balcony. A reinforcing beam for a new extension can be easily installed in the place where the cantilever beam has been removed.

[Brief explanation of the drawing]

Figures 1 (a) and (b) are schematic perspective views and schematic plan views showing the order in which the building was extended, and Figures 2 (a) and (b) show the removal of the balcony cantilever during the same extension. A perspective view of the state and a perspective view of the state in which reinforcing beams for expansion are installed, in which 1 is an exterior wall panel, 2 is a balcony, 3 is a reinforcing column, 4 is a cantilever beam for a balcony, 5 is a building, and 6 is an installation. Section 7 is a reinforcement beam for extension.

Claims (1)

[Claims] (1) When forming a balcony facing forward along multiple exterior wall panels in a building using the panel construction method, reinforcing columns are erected between the exterior wall panels, and the rear end of the balcony cantilever is attached to the reinforcing columns. When removing the fixed balcony of an existing building and building an extension, remove the balcony cantilever from the reinforcing column, and attach the reinforcing beam for the extension to the attachment point of the reinforcing column where the balcony cantilever was removed. An extension method characterized by attaching the rear end.
