Description

  The present invention relates to a construction method for a multi-story parking lot that is built into a structure such as a building.

  There is a multistory parking lot where a parking machine is built in a tower type inside a structure such as a building, but as a construction method, for example, after the structure's housing is completed, the upper part of the housing is blocked, A steel frame, a pallet, and other machines are built in the pit of the parking lot to build a tower type multi-story parking lot using a winch or the like on a hook that is driven into a frame beam or slab.

  The prior art is generally performed by those skilled in the art, and is not related to a known literature invention.

  The parking facilities are assembled in order from the lower floor to the upper floor. However, the assembly on the upper floor requires raising the material through the gap between the already-assembled lower steel frames, which is troublesome. Then, the assembly work is performed in a limited area in the pit and sequentially in a high-rise place, which is problematic in terms of safety and has poor workability.

  Moreover, the part which raises material in a pit becomes an opening part opened from the lower floor to the upper floor so as not to hinder the lifting of the material. For this reason, a protective net or the like cannot be put on the opening, and there is a great risk of falling from here.

  The present invention eliminates the inconvenience of the conventional example, and when building a tower type multistory parking lot inside a structure such as a building, assembly work in a pit, which is a limited space inside the structure, is unnecessary. It is in providing the construction method of the multistory parking lot which can improve safety | security and workability.

In order to achieve the above object, the present invention according to claim 1 is a construction method of a multilevel parking garage in which parking machines are stacked in a pit. A plurality of pits are provided in one structure, and a ground structure is provided for each pit. The number of layers of one steel frame to be made is different. A ground yard is set up on the first floor level outside the pit , and the steel frame of the multilevel parking machine is grounded in units of 1 unit in this ground yard to form a pit. Following the construction of the structure of the structure to be built, one unit of the assembled steel frame is lifted and built in the pit, and the next one unit of the built steel frame is sequentially connected on the lower structure steel frame. This is the gist.

  According to the first aspect of the present invention, since the steel frame of the multilevel parking machine is assembled at the first floor level outside the pit in the building, it is safe because there is no assembly work at a high place as in the prior art. In addition, workability is improved because there is no assembly work in a limited space in the pit as in the prior art.

  The steel frame assembled in the ground yard is unit-by-unit, lifted unit-by-unit, built in the pit, and a tower-type multistory parking lot can be constructed simply by stacking them in order, so the workability is good.

In addition, when multiple pits are provided in one structure, it is possible to lift and connect parking machines on different floors for each pit by changing the number of layers of one unit built for each pit. Work leveling can be achieved.

Further, since the steel frame unit is assembled and built in the pit using a large tower crane or the like in the construction cycle of the structural frame, the assembly period can be shortened and the construction is facilitated. In addition, since a horizontal net can be installed for each unit, it can be safely constructed.

The gist of the invention described in claim 2 is that a temporary scaffolding is constructed around four steel frames grounded at the first floor level.

According to the second aspect of the present invention, since the steel frame is laid at the first floor level, a scaffold can be erected around the structure, which is not only safe but also guides the steel frame when constructing the steel column. You can plan the guides to be done and perform grounding accurately and efficiently.

  As described above, in the construction method of the multistory parking lot according to the present invention, when a tower type multistory parking lot is constructed inside a structure such as a building, parking is performed in units in a ground yard provided on the first floor level. Since the steel frame of the machine is assembled using a mobile crane, etc., and assembled into a pit inside the structure using a large tower crane, etc., assembly work is not required in the pit, which is a limited space Therefore, safety and workability can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 11 show an embodiment of a construction method of a multilevel parking garage according to the present invention, and a process of building a steel frame for one unit and a process of erection. FIGS. It is an erection process figure of the unit of 1 section.

  This will be described from the process of assembling one unit of steel frame. Although illustration is omitted, a steel frame yard of a multi-story parking lot is provided on the first floor level outside a structure such as a building in which a multi-story parking lot is constructed. In the present invention, as shown in FIG. 15, a temporary scaffold 1 for grounding is assembled in this grounding yard, and a steel grounding is performed here.

  As a first step, the steel frame lays a laying iron plate on a yard, puts a core ink on the laying iron plate, and installs a mounting base including a bundle pillar for the laying. As shown in FIG. 15, the column 3 is lifted and built at a predetermined position by using a mobile crane 2 such as a rough terrain crane (see FIG. 1).

  As shown in FIG. 2, as the second step, the beam 4 is lifted using the mobile crane 2 as in the first step, and the beam 4 is attached from the lower stage. After the beam 4 is attached, the master rope 5 is stretched to ensure safety. In the figure, 6 indicates a ladder.

  In the third step, as shown in FIG. 3, a rebuilding set is performed using a lever block (registered trademark), a tra wire, a kito clip or the like, and a bolt is tightened using a temporary scaffold 1.

  Next, in the fourth step shown in FIG. 4, the counterweight rail 7 and the guide rail 8 are attached, and in the fifth step shown in FIG. 5, the pallet 9 is lifted by a mobile crane and attached from the lower stage. The pallet 9 is fixed to the rack by passing through a number line at two locations on the side of the pair of beams 4 facing each other (in the front-rear direction in FIG. 5). After the installation of the pallet 9 is completed, the bolts of the rack part are finally tightened.

  In the sixth step of FIG. 6, the steel scaffolding plate 10 is fixed between the pallets 9 and 9 with the connecting number wire with respect to the pallet 9 fixed in the front-rear direction at intervals as described above. Further, the handrail 11 is attached with a single tube, a clamp or the like.

  Next, as a seventh step, the horizontal net 12 is attached to the space formed between the pallets 9 as shown in FIG.

  In the eighth step, as shown in FIG. 8, rebuilding is performed using a wire, a lever block (registered trademark) or the like, and measurement is performed using the downward swing 13.

  Thus, the unit 15b for one node of the steel frame is assembled in the ground yard of the first floor level. Such work can be performed at the first floor level, and since the temporary scaffold 1 can be assembled in advance, it is safe and has good workability. When one unit 15b of steel frame is grounded, a horizontal net is attached to the lower beam in the ninth step of FIG. 9, and is lifted by a large tower crane 14 and taken into a pit of a structure such as a building (see FIG. 9). 15).

  Then, in the tenth step of FIG. 10, joining is performed on the unit 15 a for one node already installed in the pit. The upper unit 15b newly built on the lower unit 15a is fixed by tightening the bolts of the joint portion. Such work can also ensure safety because the horizontal net is installed below.

  As described above, as shown in FIG. 11, the process of building one unit newly assembled in the ground yard in the pit and connecting it to the unit built previously is repeated in the lower layer. A parking facility will be built by stacking steel frames from top to bottom.

  FIGS. 12 to 14 show the construction process of the unit of steel frames 0 to 1 which is the lowest stage. Anchor bolts are driven into the reinforced concrete foundation in the pit of a structure such as a building, and the bundle column 18 is set. To do. The bundle pillars 18 are installed using a rough terrain crane or a tower crane 14.

  Next, the building steel frame of 1 unit 15 minutes constructed as described above in the ground yard outside the building is overlaid with the tower crane 14 (see FIG. 13), and on the bundle pillar 18 in the pit. Connect (see FIG. 14).

  Since the frame of 1 unit 15 minutes is fixed in the above ground assembly, after hanging, the bolt is immediately tightened as shown in FIG. 14 to fix 1 unit 15 minutes in the pit.

  As described above, the steel frame for one unit is assembled in the ground floor yard of the first floor level, and the assembled one unit 15 is sequentially built in the pit by the tower crane 14, but as shown in FIGS. When there are a plurality of pits 19a, 19b, 19c built in the building, the height of one unit 15 built in each pit 19a, 19b, 19c, that is, the number of layers is made different. In FIG. 17, the pit 19a has one floor, the pit 19b has two floors, and the pit 19c has three floors.

  As a result, as shown in FIGS. 17 to 19, the joint positions of the units 15 are different in the pits 19a, 19b, and 19c, and the number of floors for lifting and connecting the multi-story parking machine is different. Leveling can be achieved.

  Further, the unit 15 is built and connected to the upper layer according to the progress of the construction of the housing 20 of each pit 19a, 19b, 19c. As a result, the parking lot is constructed in parallel with the housing cycle, so that construction can be performed efficiently.
