Description

  The present invention relates to a building structure suitable for a skeleton infill house.

  In a skeleton-infill house that uses a construction method that separates the skeleton of the building (structural frame) from the infill (interior interior, equipment, etc.), the skeleton is built with an emphasis on long-term durability. It is built with an emphasis on variability that can be freely changed in response to various needs.

  However, in all conventional skeleton infill houses, the floor was considered as a part of the skeleton (structural frame). For example, Patent Document 1 discloses a skeleton infill structure that includes a main structure that bears the structural strength of a building and a substructure that does not bear the structural strength and can freely design an internal space. However, the main structure is formed by joining a large number of precast concrete panels to each other, and is composed of walls that are continuous in one direction and a floor that is connected between these walls. Therefore, many patent documents (for example, JP 2005-201041 A, JP 2005-16221 A, JP 2002-309680 A, etc.) in that the floor is a part of the skeleton (structural frame). ) Is the same as the conventional skeleton infill house.

  As described above, in the conventional skeleton infill house in which the floor is a part of the skeleton (structural frame), the degree of freedom of variability of the infill part is reduced accordingly, for example, a house that is desired as the economic situation changes In order to respond to changes in society's needs, such as lowering the price of the house, or lowering the price, and reducing the size of each dwelling unit due to the declining birthrate and aging population, the floor can be removed by adding or removing floors. It was difficult to make major modifications to the internal space, such as changing or providing a vent.

  By the way, in Patent Document 2, as a seismic reinforcement structure of an existing building, a reaction wall is constructed on both ends of the existing building, and the reaction force wall and the existing building are tensioned and fixed by PC steel material arranged on each floor. Thus, a technique for introducing prestress into an existing building is disclosed. Patent Document 3 discloses a technique for binding a precast concrete column and a concrete beam by a PC crimping method.

  If it is a high-rigidity, high-proof bearing wall such as the reaction wall described above, a wall-type skeleton (structural frame) that can bear all the seismic force is constructed by placing the bearing wall around the building. It is possible. Moreover, the PC crimping method for binding the precast concrete member as described above can be used as a dry bonding method for the prefilled concrete infill portion and the load bearing wall.

  In addition, as a beam, the vibration control beam provided with the vibration control mechanism other than the general beam rich in rigidity and proof stress may be sufficient (Claim 4). Further, in the above-mentioned building structure, the load-bearing wall may surround the surrounding four surfaces of the building (Claim 5), or the load-bearing wall may surround the three surrounding surfaces of the building and one surface of the building may be opened. Good (Claim 6).

  Invention of Claim 7 is the building structure in any one of Claims 1-6, Comprising: It is comprised by crimping and joining the precast concrete member in which the load-bearing wall was unitized with PC steel materials. It is characterized by that.

  Invention of Claim 8 is a building structure in any one of Claims 1-7, Comprising: A part in building structure is fixed with respect to a load-bearing wall, and for several PC steel material insertion The through-hole is composed of a reaction slab with high rigidity and high yield strength formed at predetermined intervals.

  The invention according to claim 12 is the building structure according to any one of claims 1 to 11, characterized in that it is supported by a seismic isolation bearing.

According to the first aspect of the present invention, a building structure suitable for a skeleton infill house is realized. That is, the outer wall is composed of a bearing wall, and a plurality of PC steel material insertion through holes are formed in the bearing wall at predetermined intervals, and the PC steel material inserted into these through holes constitutes the floor inside the floor building. Since the horizontal member is pressure bonded to the bearing wall and the floor position can be changed by selecting the through hole into which the PC steel material is inserted, the floor is infilled. Therefore, the degree of freedom of variability of the infill part can be remarkably increased.For example, in order to respond to the changing needs of society, the floor is removed or the floor of the building is changed by adding a floor, The internal space can be significantly modified by providing a vent. Here, the horizontal member constituting the floor inside the floor building means at least one of a beam and a floor slab, and a form in which only the beam is pressure-bonded to the bearing wall and the floor slab is supported by the beam, It is a concept that includes a method in which the floor slab is directly bonded to the bearing wall and the beam is omitted, or a combination of both.

  According to invention of Claim 2, in addition to said effect, the bearing wall arrange | positioned at an outer wall is a highly rigid and highly proof bearing wall which can bear all the seismic force which acts on a building structure. For this reason, members such as columns, beams, and walls disposed in the interior do not need to bear the seismic force, and need only satisfy structural performance with respect to their own weight, finish, and load that are always generated. Therefore, simplification of the member joint portion, rational cross-sectional design, and free member arrangement are possible.

  According to invention of Claim 3, in addition to said effect, the building structure which has an outer wall with many opening is implement | achieved, and the architectural design diversity can also be ensured.

  According to the invention described in claim 4, in addition to the above effect, the beam is provided with a vibration control mechanism. Therefore, the vibration control mechanism can efficiently absorb the earthquake energy, and the proof stress arranged on the outer wall. It is possible to prevent damage to the wall. Moreover, since the damaged part after an earthquake can be concentrated on the damping mechanism part, the repair after an earthquake is easy and the life of a building can be extended.

  According to the fifth aspect of the present invention, in addition to the above effects, the bearing walls are installed on the four surfaces around the building, so that problems such as torsional vibration are unlikely to occur during an earthquake.

  According to the invention described in claim 6, in addition to the effects of the inventions of claims 1 to 4, since the bearing walls are installed on the three surfaces around the building, a large opening can be formed on the remaining one surface. it can. By taking measures such as increasing the thickness of the bearing wall on the side facing the opening, it compensates for the decrease in the yield strength of the opening, and since the planar shape is U-shaped, the bearing walls on the three surrounding surfaces cooperate. It is also possible to improve torsional rigidity by acting. Therefore, it is possible to take a large opening while ensuring structural safety. The invention according to claim 6 faces the main street, for example, so that one surface is required to be open, but the other three surfaces (the side and back of the building) are in contact with adjacent buildings and open. Suitable for buildings where sex is not required.

  According to the seventh aspect of the invention, in addition to the above effect, the precast concrete member in which the bearing wall is unitized is formed by pressure bonding with the PC steel material. By moving the position of the concrete member, it is possible to change the planar shape of the building structure, that is, the shape of the outer wall constituted by the bearing wall. Furthermore, when the building is exhausted, when the building is dismantled, the dismantling operation can be easily performed by cutting the PC steel material.

  And by precasting the outer wall that requires high yield strength and durability, it can be manufactured at the factory, so quality control is easy. In addition, by introducing prestress to the bearing wall, it is possible to prevent cracking due to the tensile force generated in the bearing wall during an earthquake, and to prevent the crack from developing due to drying shrinkage and temperature fluctuation. Furthermore, the precast property improves the workability of the load-bearing wall.

According to invention of Claim 8, in addition to said effect, a part in building structure was fixed with respect to the load-bearing wall, and the several through-hole for PC steel material insertion was formed at predetermined intervals. Since it is composed of a high-strength and high-strength reaction slab, for example, the inner wall can be suspended and supported by PC steel like a vertical wall from any position of the reaction slab that constitutes the roof. The inner wall can be set up like a waist wall at an arbitrary position on the reaction force slab constituting the lower floor. Furthermore, by making any intermediate floor a fixed floor, out-of-plane deformation of the load-bearing wall of the outer wall can be prevented at the fixed floor position. Therefore, improvement in the integrity of the bearing walls and an improvement in the buckling strength in the out-of-plane direction of the bearing walls can be expected, and the earthquake resistance of the building structure is improved.

  Here, the floor “fixed to the bearing wall” means a floor whose installation position is fixed as a part of the skeleton.

  According to invention of Claim 9, in addition to said effect, a floor can be arrange | positioned in the arbitrary height between the load-bearing wall used as an outer wall, and the core wall inside a building, The inside of a core wall is It can be used as an elevator shaft, staircase, common vertical pipe installation space, etc. In addition, by placing the core wall inside the building, the support span of the members (beams and flooring) that make up the floor inside the building can be shortened, and it is possible to improve the flexibility and vibration properties. At the same time, rational design of the member dimensions becomes possible.

  According to the invention described in claim 10, in addition to the above effects, the floor is constituted by a beam member that is pressure-bonded to the load-bearing wall by a PC steel material inserted into the through hole, and a floor panel laid on the beam member. Therefore, the floor panel does not need to be bonded to the load-bearing wall by crimping, and the member to be bonded to the load-bearing wall is limited to the beam, so that the pressure-bonding work can be reduced and the floor construction is easy. The beam member may be a reinforced concrete structure, a steel reinforced concrete structure, or a steel structure. Further, not only prestress for pressure bonding but also prestress for extending the support span may be introduced into the beam member.

  According to the eleventh aspect of the invention, in addition to the above effect, the exterior material is attached to the outer surface of the load bearing wall by the PC steel material inserted into the through hole of the load bearing wall. The fixed and tension ends of steel can be concealed to improve the design of the building, and the position and shape of the exterior can be selected freely, enabling a variety of exterior finishes.

  According to invention of Claim 12, in addition to said effect, since a building structure is a seismic isolation structure supported by the seismic isolation bearing, it is possible to lengthen the building, and the upper part of the base isolation bearing Can reduce the seismic force generated in buildings. Therefore, damage to the bearing wall can be reduced, and since the acceleration at the time of the earthquake can be suppressed small, the fear of the building user can be suppressed. Therefore, the building life can be further increased, and a building structure that is safe, secure, and durable can be realized.
