Description

  The present invention provides a seismic reinforcement that is capable of withstanding horizontal stress during an earthquake by reinforcing a shaft assembly in contact with an opening for attaching a window by attaching a reinforcing member to a window frame constituting a window of a wooden building. It is about windows.

Since the Great Hanshin-Awaji Earthquake, earthquake countermeasures have been especially important, and various proposals have been made and put into practical use.
For example, in the case of wooden buildings, which are common in detached houses, the minimum value of the total wall amount is set by the Building Standards Law in order to increase earthquake resistance. There is a tendency to have a large opening area (sweep window, etc.) for large areas, while on the north side, a small area opening area such as a small window is formed to secure heat loss or the total wall amount Often to do. In these detached houses, the center of gravity of the building and the position of the rigid center are largely separated from each other, and are often eccentric. In such a building, a torsional moment is generated in the building due to the horizontal stress in the event of an earthquake, and in the worst case, the building collapses.
In order to deal with this, seismic reinforcement has been carried out in old wooden buildings that have been aged in recent years. In general, the seismic reinforcement is to attach a reinforcing hardware to a joint portion of a structural frame (base, column, beam) of a wooden building.

By the way, because it is difficult to attach reinforcement hardware etc. to the opening for installing windows of wooden buildings due to external restrictions, reinforcement hardware etc. is located at the intersection of horizontal and vertical directions like pillars and girders. It is attached (for example, refer to Patent Document 1). In this way, when performing seismic reinforcement, it is necessary to construct a large number of braces and reinforcement hardware on inconspicuous parts such as the interior of the wall (building frame). When performing, there are many cases where the outer wall has to be peeled off, and there is a problem that it takes a lot of man-hours.
Incidentally, there has been proposed a structure (see Patent Document 2) in which a reinforcing plate for reinforcing a frame assembly is attached in the plane of an opening to which a window of a wooden building is attached. It is necessary to perform the construction in the plane of the glass), and it is difficult to fit the window frame, and in particular, there is a problem that the heat insulation property of the opening is hindered.
In addition, as a structure that directly reinforces the opening for attaching a window of a wooden building, the applicant proposed earlier, attaching a wooden seismic opening frame to the opening, while ensuring the same daylighting as before. There is one in which the assembly is reinforced (see Patent Document 3).

The present invention further improves the structure previously proposed by the applicant of the present invention for directly reinforcing the opening for attaching the window of the wooden building, and by attaching the reinforcing member to the window frame constituting the window of the wooden building, The shaft assembly that is in contact with the opening to which the window is attached is reinforced to withstand horizontal stress during an earthquake. More specifically, the object is to solve the following problems.
(1) By adding rigidity to the window, it is possible to contribute to the amount of walls by adding functions similar to those of structural members. The center of gravity of the building and the position of the rigid center are brought close to each other so that the building collapses in the event of an earthquake. To reduce eccentricity, one of the elements to prevent, and torsional moment generated in buildings.
(2) A window with improved rigidity secures an opening space in the event of a major earthquake, and leads to securing an escape route.
(3) When renovation such as refurbishment to improve earthquake resistance, the work can be easily performed with less man-hours without peeling off the outer wall.
(4) The window frame fits well and does not interfere with the heat insulation of the opening.

The seismic reinforcement window of the present invention is based on the concept of the structure that the applicant previously proposed to directly reinforce the opening for attaching the window of a wooden building, and the window frame itself constituting the window of the wooden building has rigidity. By giving, it solves the said subject.
More specifically, the earthquake-resistant reinforcing window of the present invention has four sides and forms a quadrangular shape, and the earthquake-resistant reinforcing member intermediate plate between the adjacent earthquake-resistant reinforcing members and the earthquake-resistant reinforcing member at the four corners of the window frame. Are each integrally bonded to a window frame.

  In this case, the seismic reinforcing member can be made of a material having high rigidity and toughness such as a metal such as iron or a reinforced plastic.

  Further, the seismic reinforcement member can be formed of a material having an L-shaped cross section and in a shape along the external shape of the window frame.

  Moreover, a reinforcing material can be arrange | positioned inside a window frame, and an earthquake-resistant reinforcing member and an earthquake-resistant reinforcing member intermediate | middle plate can be joined to this reinforcing material via a window frame.

  Further, the window frame can be configured to have a hollow shape for disposing the reinforcing material.

  Further, the reinforcing material can be formed in a shape made of a square pipe material and along the internal shape of the window frame.

  Further, the earthquake-resistant reinforcing member and the earthquake-resistant reinforcing member intermediate plate can be integrally disposed by being joined by the earthquake-resistant reinforcing member connecting plate.

  In addition, the earthquake-resistant reinforcing window can be fixed to the shaft assembly portion of the opening of the wooden building via the earthquake-resistant reinforcing member by a fixing bracket such as a screw or a nail.

  Moreover, the thing made from a synthetic resin can be used for a window frame.

  In addition, the seismic reinforcement window of the present invention includes an outer window, a sliding window, a drape window, a window window, a double window, a vertical sliding window, a horizontal sliding window, a bay window, a vertical sliding window, a door, and a combination of these. It can be applied to any of the windows.

The earthquake-resistant reinforcing window of the present invention is provided with an earthquake-resistant reinforcing member and an earthquake-resistant reinforcing member intermediate plate made of a highly rigid material at the four corners and the outer peripheral part of the four sides of a window frame made of synthetic resin or the like, and if necessary, an earthquake-resistant reinforcing member and The seismic reinforcement member connecting plate that joins the middle plate of the seismic reinforcement member is reinforced with a window frame, more specifically, a square pipe material arranged inside the window frame to transmit the horizontal stress from the pillar. This is an anti-seismic function that suppresses the horizontal stress to the window where the horizontal stress is transmitted from the column in the event of an earthquake. In order to withstand horizontal stress during an earthquake, the problems (1) to (4) can be solved.
Moreover, members, such as a seismic reinforcement member joined to a window frame, can be constructed like a normal window frame by setting it as the shape along the shape of the window frame.
As described above, the earthquake-resistant reinforcing window of the present invention includes the earthquake-resistant reinforcing member and the earthquake-resistant reinforcing member intermediate plate for supplementing the function of suppressing the deformation of the structural body in the event of an earthquake, and if necessary, the earthquake-resistant reinforcing member and the earthquake-resistant reinforcing member. The seismic reinforcing member connecting plate that joins the intermediate plate is joined to the window frame, and the seismic reinforcing member joined to the four corners of the window is used to deform the frame part of the opening for attaching the window of the wooden building. Suppressing and preventing the bending stress and buckling of the column part by the anti-seismic reinforcing member intermediate plate joined to the four sides of the window, ensuring the shape of the opening part and ensuring the opening part as an evacuation route Can be connected.
Moreover, by applying the seismic reinforcement window of the present invention to the renovation for improving the earthquake resistance of the existing wooden building, it is possible to serve both the seismic reinforcement of the opening and the heat insulation repair.
In addition, while the seismic reinforcement member is integrated, it is possible to ensure the same fit as an ordinary window from the exterior and the inside view, and there is no sense of incongruity in appearance.
Moreover, when constructing the seismic reinforcement window of the present invention, it is not necessary to peel off all the outer walls, and the effect can be exhibited only by replacing the window or the window frame, and it can be made into a structural member by a very general window frame construction method. For this reason, it is possible to reduce the number of man-hours required for the construction and to suppress the cost required for the construction.
