Description

  The present invention relates to a method for preserving an existing structure that partially preserves an existing outer wall that constitutes an existing structure, and uses the outer wall of an existing building having a high historical value as part of the outer wall of a new building. It is related to the old- and new-building integrated thatched-house method applicable to the above.

  In recent years, modern buildings are often demolished for reasons such as aging and earthquake resistance. However, focusing on historical value, one of the structural members that make up a building. The department is preserved by using it as part of the outer wall of a new building.

In the case of moving the preservation outer wall and incorporating it as a part of the outer wall of a new building, the following procedure is used in the conventional technique.
(1) Reinforce the structure with a temporary steel frame or the like so that the outer wall to be stored and moved does not fall.
(2) Dismantle internal pillars, beams, floors, etc. that are not preserved.
(3) Only the outer wall to be stored / moved remains in a plate shape in a state supported by the temporary steel frame.
(4) Further temporary reinforcement for moving (iron plate reinforcement, carbon fiber reinforcement, prestress reinforcement, etc.) is applied as necessary so that the storage outer wall does not break during movement.
(5) Move the preservation outer wall to the position of the outer wall of the new building.
(6) Remove the temporary reinforcement for movement that will interfere with the construction of the new building.
(7) Work on pillars and beams of the new building to structurally integrate the preservation outer wall and the new building.
(8) Dismantling the temporary steel frame and the like for preventing the fall.

In addition, the following patent document proposes an existing outer wall structure to be stored so that it can stand on its own, constructs a reinforcing frame in the vicinity of the back side of the existing outer wall structure, and supports it through a support member. In addition, a point near the top of the reinforcing frame and an extended floor provided from the newly-constructed structure toward the reinforcing frame are connected through a connecting member with a pin roller support having a pin roller support capable of horizontal movement and rotation. By supporting, the structural safety of the existing outer wall structure supported by the reinforcing frame is ensured.

  According to Patent Document 1, an existing outer wall structure to be stored is supported by a reinforcing frame arranged in parallel on the back surface side with a predetermined separation interval, and the reinforcing frame is the same size as the existing outer wall. A reinforcing frame body having a vertical surface, and a plurality of support members provided on one vertical surface of the reinforcing frame body at predetermined intervals in the height direction and projecting horizontally toward the existing outer wall structure. Since the end of the support member is fixed to the back surface of the existing outer wall structure via a fixing means, the rigidity of the existing outer wall structure is excessively increased by being supported by the reinforcing frame. Therefore, even when an out-of-plane force is applied and an out-of-plane bending deformation occurs, a large bending moment is generated in the vicinity of the joint with the existing foundation reinforced at the bottom of the existing outer wall structure. Rather, there becomes possible to suppress damage of the existing outer wall structure.

Furthermore, the following patent document is a first method of forming a pair that stands integrally on each of the existing outer wall constituting the existing structure and both sides of the existing outer wall as a method for preserving the existing outer wall structure that is not affected by site conditions or the like. The preservation method of the existing outer wall structure which preserve | saves the existing outer wall structure which consists of existing pillars of a part is proposed.

  This Patent Document 2 is directed to the back surface of an existing outer wall structure that is desired to be preserved, and a second existing pillar that forms a pair standing upright at a position facing the first existing pillar, and the second existing pillar adjacent to the second existing pillar. The existing frame structure is dismantled by leaving the existing frame structure composed of a plurality of existing beams connecting the second existing column and the first existing column, and then the inside of the existing frame structure And constructing a temporary frame that supports the existing outer wall structure, and supporting the existing outer wall structure with the temporary frame, and then the ground portion of the second existing column that forms a pair constituting the existing ramen frame and Dismantle existing beams.

  According to Patent Document 2, since a temporary frame that temporarily supports an existing outer wall structure is built in the site of the existing structure, it can be used universally without depending on site conditions around the existing structure. Become.

  In addition, the existing outer wall structure constitutes an existing ramen frame that can be self-supported together with the second existing column and the existing beam, and after dismantling other existing structures leaving the existing ramen frame, a temporary frame is constructed. Therefore, a temporary frame can be constructed in parallel with the new construction of the site of the existing structure that has been demolished, the work period can be shortened, and the construction work of the temporary frame can be carried out using heavy machinery used for the new construction. Therefore, workability can be greatly improved.

  In the conventional technique in which the preservation outer wall is moved and incorporated as a part of the outer wall of a new building, the number of processes is large and a complicated procedure is required.

  Patent Documents 1 and 2 focus on a method for preserving an existing outer wall structure, and suppress the damage to the existing outer wall structure and realize the preservation of the existing outer wall structure that is not affected by site conditions or the like. The preservation outer wall is not moved and incorporated as a part of the outer wall of the new building.

  In particular, if the plane position relationship between the preservation outer wall and the new building is shifted, or the preservation outer wall is moved (thatched) due to the securing of open space and the outer wall setback from the road boundary, It cannot be used in such a case.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and to use the outer wall of an existing building as a part of the outer wall of a new building. It is an object of the present invention to provide a new and old building-integrated construction method that can reduce the temporary reinforcement for moving and the temporary reinforcement during the movement, and can be realized at low cost with few processes.

  In order to achieve the above object, the present invention as claimed in claim 1 is to construct a new building at a planar position before the preservation outer wall is moved, and to integrate the structure frame of the new building before moving the preservation outer wall. The gist is to move the preservation outer wall and the structural frame of the new building to the new building position at the same time by using a thatched house and integrate the structural frame of the new building with the foundation.

  According to the first aspect of the present invention, the temporary reinforcement for preventing the storage outer wall from falling and the temporary reinforcement during the movement can be reduced, and the column, beam, wall, and slab of the new building are prevented from falling. By using it as a reinforcing material for the preservation outer wall for movement and RC reinforcement (reinforced concrete reinforcement) for the preservation outer wall, deformation can be suppressed, which is effective in preventing cracks.

  The present invention according to claim 2 is a planar position before the movement of the preservation outer wall, and the arrangement and span splitting are performed by assembling the temporary steel frame according to the pillar / beam position of the new building, and before moving the preservation outer wall. The gist is to integrate the timber and the preservation outer wall, move the preservation outer wall and the temporary steel frame to the new building position at the same time, fix the temporary steel frame to the foundation etc., and drive it into the concrete in the new structure frame Is.

  According to the second aspect of the present invention, as in the first aspect, the temporary reinforcement for preventing the storage outer wall from toppling over and the temporary reinforcement during the movement can be reduced. Can be omitted.

  As described above, the new and old building-integrated thatched roof method of the present invention uses the outer wall of the existing building as a part of the outer wall of the new building. Therefore, the temporary reinforcement for preventing overturning and the temporary reinforcement during the movement can be reduced, and it can be realized at low cost with a small number of processes.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a first embodiment of a new and old building-integrated thatched-house method according to the present invention, FIG. This preservation | save outer wall 1 is a case where it is an outer wall of the existing building with high historical value, and uses this as a part of outer wall of a new building.

  In the present invention, columns, beams, walls, and slabs of a new building are used as a reinforcing material for the preservation outer wall 1 for preventing and moving over.

  At the plane position before the preservation outer wall 1 is moved, the frame construction for constructing the pillar 3, the beam 4, the wall 5, and the slab 6 as the structural frame 2 of the new building is performed.

  The preservation outer wall 1 and the structural frame 2 of the new building are integrated. Various methods can be adopted for this integration. In the example shown in the figure, a cross beam H steel 7 for connection is projected from the structural frame 2 of the new building, and this is passed through the storage outer wall 1 to connect the connection bolt (φ16) 8. Fix with etc.

  Further, when the storage outer wall 1 is high in height, a support 9 made of H-shaped steel standing from the structural frame 2 of the new building is attached to the storage outer wall 1 and is also fixed from the support 9 by welding. The horizontal beam H steel 7 is protruded, penetrated through the storage outer wall 1, and fixed with a connecting bolt (φ16) 8 or the like.

  The preservation outer wall 1 and the new structure frame 2 are simultaneously moved to the new building position with a straw. The thatched house is to move an existing building to a place where there is no problem in its existence, and although the rail 10 and the illustration are omitted, a moving mechanism that moves the rail 10 and a temporary receiving jack 11 that supports the temporary receiving are used. To do.

  As the moving mechanism, a sliding mechanism that slides on the rail 10 or a rolling mechanism that uses a roller or the like is preferably used, as various known and used in the existing thatching method.

  The integrated storage outer wall 1 and the structural frame 2 of the new building are supported by a temporary receiving jack 11 to perform load re-loading. And the preservation | save outer wall 1 and the structure frame 2 of a new building are cut off from a lower structure and a foundation, and are temporarily received and supported on the rail 10 via the moving mechanism of the structure which can implement thatched-house construction method.

  After the preparation of thatched house in this way, next install a horizontal jack (not shown) for thatched shop, move it along the rail 10, and have already prepared on the foundation 12 for the new building The preservation outer wall 1 and the structure frame 2 of the new building are made to reach the bottom of the temporary receiving foundation structure, and the structure frame 2 of the new building is integrated with the foundation 12 and the like.

  3 and 4 show a second embodiment of the present invention. The difference from the first embodiment is that the temporary steel frame 13 is used as a reinforcement instead of the structural frame 2 of the new building. However, the temporary steel frame 13 is arranged in accordance with the positions of the columns and beams of the new structure frame so that it does not have to be removed as a temporary material.

  The temporary steel frame 13 is assembled at a planar position before the preservation outer wall 1 is moved. The temporary steel frame 13 is composed of a temporary steel column 14, a temporary steel beam 15, and the like, and the arrangement and span splitting are adjusted to the columns and beam positions of the new building.

  The temporary steel frame 13 and the storage outer wall 1 are integrated to be reinforced. In this integration, as in the first embodiment, the cross rail H steel 7 for connection is protruded, penetrated through the storage outer wall 1 and fixed with a connection bolt (φ16) 8 or the like.

  The preservation outer wall 1 and the temporary steel frame 13 are simultaneously moved to the position of the new building by a thatched shop. About the thatched-house construction method, it is as having demonstrated the said 1st Embodiment.

  The preservation outer wall 1 and the temporary steel frame 13 are made to reach, the temporary steel frame 13 is fixed to the foundation 12 or the like, and this temporary steel frame 13 is driven into the concrete in the newly constructed frame.

  When the new building is a reinforced concrete structure, the temporary steel frame 13 to be driven into the concrete in the new structure frame is simply driven. When the new building is a steel reinforced concrete structure, the temporary steel frame 13 is used as a permanent steel frame to construct a new structure frame of the reinforced steel concrete structure.
