Japanese Patent Laid-Open No. 8-120961

  In recent years, the construction of high-rise apartments has become popular. High-rise apartments have a structure with many residents in a small area, and securing a parking lot may be a problem. Therefore, in a recent high-rise apartment, a parking lot is secured by forming a multi-level parking lot along the height direction of the building enclosure inside the building enclosure. Moreover, when constructing such a multistory parking lot, the construction method of the multistory parking lot disclosed in Patent Document 1 can be used.

  However, when constructing a multistory parking lot on a structure such as a super high-rise apartment building using the construction method for a multistory parking lot disclosed in Patent Document 1, one of the structural body and the multistory parking lot is constructed first. After the construction is completed, the other is constructed. In this case, there is a problem that the construction period for constructing the apartment building and the multi-story parking lot is increased, and the construction period may be prolonged.

  In addition, when constructing the apartment building, a lift-type scaffolding is installed, but the scaffold itself may fall, and the safety may be reduced accordingly. Furthermore, in order to ensure safety, it is necessary to install a scaffold and a horizontal net for preventing fall as construction progresses. However, when carrying in the materials used for the construction of the apartment building, these scaffolds and horizontal nets had to be removed once, and there was a problem that workability and safety could be reduced accordingly. .

  Therefore, the object of the present invention is to provide a multi-story parking structure that can prevent the lengthening of the construction period and achieve both workability and safety when constructing a multi-story parking lot along the height direction of the structure. The purpose is to provide a method of constructing a parking lot.

  Further, the jack equipment can be a center hole jack. Although the jack equipment is not particularly limited, for example, a center hole jack can be suitably used.

  Furthermore, a jack-up support member for supporting a jack-up body jacked up by the jack equipment at the time of jack-up is provided, and after the jack-up body is jacked up several times, the jack-up support member is When the jack up support member is replaced, a support structure for supporting the multistory parking lot can be provided.

  When rearranging the jack-up support member, since the restraint of the multi-story parking lot by the jack is released, measures such as a fall of the multi-story parking lot become a problem. In this respect, by providing a support structure for supporting the multilevel parking lot when the jackup support member is replaced, preventing the falling of the multilevel parking lot when the jackup support member is changed Can do. The “jack-up body” in the present invention refers to the entire multistory parking lot frame jacked up by jack equipment.

  And a building frame can be made to be a building frame of a high-rise building. When the building frame is a high-rise building such as a super high-rise apartment, the number of times lift-up is required increases. Therefore, it is possible to prevent the construction period from being prolonged more efficiently.

  Next, the construction procedure of the multistory parking lot P according to the present embodiment will be described. The multilevel parking lot P according to the present embodiment is performed simultaneously with the construction of the core wall of the building frame T in the super high-rise apartment M. Hereinafter, the construction procedure of the building frame T and the construction procedure of the multistory parking lot will be described together. FIG. 6 is a process diagram showing a part of the construction procedure of the building frame, and FIG. 7 is a process diagram showing a part of the construction procedure of the multistory parking lot.

  In performing the construction of the building frame T, first, when the construction of the floor frame of the first floor in the super high-rise apartment M is completed, the steel frame of the multilevel parking lot for one to several floors is erected in advance. The column of the steel frame is the column member 1. In the first stage, a steel frame for the third floor is constructed and a parking space part is constructed. The parking space part constructed first is the top floor part in the multistory parking lot. Moreover, the parking space part provided below becomes a lower layer part. At this time, in order to proceed with the construction of the core wall at the same time, a building frame construction facility such as a crane C is mounted on the top of the constructed parking space.

  When constructing the core wall, the sheath tube 14 is embedded in the third floor portion of the core wall. However, it can be set at a position other than the third floor. When the construction of the parking space portion proceeds to the third floor as it is, the PC steel rod 15 is tensioned on the sheath tube 14 to fix the jack receiving bracket 13 to the core wall. This jack receiving bracket 13 is disposed in the space between the pillar member 1 and the core wall at the four corners of the multilevel parking lot through the same procedure.

  Subsequently, the jack 11 is placed on the jack receiving bracket 13, and the jack 11 and the jack receiving bracket 13 are joined by a bolt or the like. Then, the PC steel stranded wire 12 is passed through the jack 11 which is a center hole jack, and the PC steel stranded wire 12 is sandwiched between chucks (not shown) provided at the upper and lower portions of the jack 11 so that the jack 11 and the PC steel stranded wire are inserted. 12 is connected.

  Thereafter, the construction of the core wall and the lift of the multi-story parking lot using the jack 11 are performed by the building frame construction equipment such as a crane provided at the top of the multi-story parking lot. When building the core wall, a scaffold is built and a horizontal net is stretched. Hereinafter, the construction of the core wall and the procedure for lifting the multi-story parking lot will be described. In constructing the core wall, as shown in FIG. 6 (a), using a crane C or the like provided at the top of the multistory parking lot, the T (n) portion corresponding to the nth floor of the core portion is enforced. Do.

  Next, when the enforcement of the T (n) floor portion is completed and the construction for the first floor of the multilevel parking lot is completed, the multilevel parking lot P is lifted up. Along with the lift of the multilevel parking garage P, the crane C and the like are also lifted up, and as shown in FIG. 6B, the construction of the T (n + 1) floor on the first floor of the T (n) floor is performed.

  When the multi-story parking lot is lifted up according to the procedure shown in FIG. 7, the lifting bracket 17 is joined to the steel frame to be the pillar member 1 with a bolt or the like and the suspension bracket 17 is received. Then, the suspended beam 16 is joined. At this time, the hanging beam 16 and the hanging bracket 17 are joined by bolts, so that the refilling is easy. In this procedure, four hanging beams 16 are attached and installed in such a form as to hold the column member 1. Then, a PC steel strand 12 is suspended between the jack 11 and the suspension bracket 17, and the suspension beam 16 is suspended by the jack 11.

  Then, as shown in FIG. 7 (b), the suspension beam 16 is lifted up by pulling up the wire 12 from the PC steel by the jack 11. At this time, since the jack 11 is provided on the jack receiving bracket 13 fixed to the core wall W, the reaction force can be applied to the core wall W to jack up. The suspended beam 16 is fixed to the column member 1 to which the nth horizontal frame member P (n) located in the lowermost layer is connected. For this reason, the column member 1 of the multilevel parking garage fixed to the suspension beam 16 is also lifted by lifting the suspension beam 16.

  Thus, when the hanging beam 16 is lifted up by one floor, a space is created below the hanging beam 16. Thereafter, as shown in FIG. 7C, the steel frame and the (n + 1) th horizontal frame member P (n + 1) to be the pillar member 1 are erected in the space formed below the hanging beam 16. At this time, beams, guide pillars, pallets, counterweight rails, and the like used for the multilevel parking lot are erected to form a parking space portion.

  Thereafter, the lift-up process of the hanging beam 16 is repeated a plurality of times, here three times. While the lifting of the suspended beam 16 is repeated three times, the T (n + 1) floor portion is formed on the core wall from the state shown in FIG. 6 (a), as shown in FIG. 6 (b). ), A T (n + 2) floor portion is formed, and as shown in FIG. 6D, a T (n + 3) floor portion is formed.

  At this time, a roller 21 is provided for each of several floors of the multilevel parking lot P as a mechanism that rolls while temporarily receiving the multilevel parking lot P when tilted. By providing the roller 21, the inclination of the multi-story parking lot P is prevented. Further, during the lift up of the multistory parking lot P, installation adjustment and bolt tightening are performed. Furthermore, in order to ensure workability and safety, a pallet crossing scaffolding, a master rope, and a horizontal net will be installed.

  When the lifting of the suspension beam 16 is three times, the suspension beam 16 approaches the height of the jack 11 as shown in FIG. 6D, and the suspension beam 16 cannot be lifted up by the jack 11 beyond this. It becomes a state. At this time, the sandwiching of the wire 12 from the PC steel by the jack 11 is released, and the hanging beam 16 is lowered. At this time, since the column member 1 cannot be supported by the jack 11, the lower end portion of the column member 1 is placed on a column temporary receiving port (not shown) which is the support structure of the present invention, and the column member 1 is vertically The load is transferred to the building frame.

  Thereafter, the lowered suspended beam 16 is joined to the lower end portion of the column member 1 located at the lowermost layer. Thereafter, the same process is repeated, and the construction of the multistory parking lot P and the core wall is continued. And by reaching the top floor of the super high-rise apartment M, the construction of the multistory parking lot P and the core wall is completed.

  Thus, in the construction method of the multistory parking lot in the super high-rise apartment according to the present embodiment, the top floor portion in the multistory parking lot P is constructed, and the crane C or the like for constructing the building frame is mounted on the top floor portion. The jack 11 is repeatedly jacked up to construct the core wall W and the multistory parking lot P of the building frame. For this reason, the construction of the multistory parking lot P and the construction of the core wall W can be performed in parallel. Therefore, when constructing the multilevel parking lot P along the height direction of the super high-rise apartment, it is possible to prevent the construction period from being prolonged.

  Moreover, when constructing the core wall, since the multistory parking lot under construction can be used as a scaffold, construction of the core wall is facilitated. Furthermore, since the construction can be performed in a state where the horizontal net is stretched on the multistory parking lot, the safety can be ensured accordingly. Furthermore, since the scaffold can always be assembled above the core wall, it is possible to prevent the scaffold from collapsing and to reduce the labor required for installing the scaffold. As a result, both workability and safety can be achieved.

  In addition, when the multistory parking lot P is lifted up, a tilt prevention structure that prevents the multistory parking lot P such as the roller 21 from tilting is provided. For this reason, the inclination of the multistory parking lot P at the time of lift up can be prevented suitably. In addition, the column member is placed on the column provisional receiving port when the suspended beam 16, the suspended bracket 17, the suspended piece 18 and the like are rearranged. For this reason, the fall of the multistory parking lot at the time of reordering can be prevented.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above embodiment, the structure is a super high-rise apartment, but other high-rise buildings such as hotels and commercial facilities and other structures may be used. Moreover, in the said embodiment, although the center hole jack is used as a jack, another jack can also be used.
