Abstract

PURPOSE: To reduce building units, by constituting an elevator with pulleies hooking ropes to suspend a lifting cage and fixing the pulleies to a beam installed in the uppermost floor building unit of a plurality of building units. CONSTITUTION: A pair of reinforcing beams 27 arranged parallelly to each other are laid between the upper beams 19, 21 of the third floor building floor 16A. And studs 28, 30 are erected between the upper beams 19, 21 and the lower beams 23, 25 at both ends of the beam 27 to prevent the upper beams 19, 21 on which the beams 27 are supported from warping, by the studs 28, 30. Beams 17 fixing pulleies 6 are laid between the beams 27. Temporary beams 41 are fitted to the lower beams 23, 25 at the fabrication of the building unit 16A in a factory and a lifting cage is placed on a beam for tools to temporarily fix it. When assembling the building unit 16A at the construction site, the rope of the lifting cage is connected to the drum of downward lifting device and the temporarily fixed state of the lifting cage is released to remove the temporary beams 41. In this way, a steel tower fitting pulleies becomes unnecessary and the building cost is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit building with an elevator having an elevator inside the building.

[0002]

2. Description of the Related Art Conventionally, as a unit type house having an elevator inside, there is one disclosed in JP-A-5-310381. According to this, in the elevator shaft formed in the unit-type building, a steel tower supporting the elevator car of the elevator is provided so as to vertically penetrate the floor of the building, and a rope for hanging the elevator car is provided. It is hung on a pulley attached to the top of this tower.

That is, when such a steel tower is provided, the steel tower has a structure in which the total weight of the elevator car due to the weight of the elevator car or the load in the elevator car is passed through a pulley provided in the upper part. There is.

[0004]

However, such a steel tower is complicated in its structure because it is required to be able to withstand the above-mentioned load under the constraint that it is arranged in a narrow elevator shaft. In addition, since the number of parts increases, there is a problem that it takes time to manufacture a steel tower.

Further, the provision of the steel tower requires the production and installation work of the steel tower in addition to the building units constituting the unit type building, and therefore, it is expensive as a general house and the building There was also the problem of high costs.

An object of the present invention is to provide a unit building with an elevator, which can eliminate the need for a steel tower to which pulleys are attached and can reduce the cost of the building.

[0007]

An elevator-equipped unit-type building of the present invention is constructed by combining a plurality of building units produced in a factory up and down at a construction site, and the elevator-equipped unit is installed inside. In a building, the elevator is configured to include a pulley on which a rope for suspending an elevator car is hung, and the pulley is attached to a beam provided on a top floor building unit among a plurality of building units. Characterize.

Here, the top floor building unit is a building unit arranged in the top floor of the floors in which the elevator car can be raised and lowered. For example, in a four-story unit type building, the first floor and the third floor If the elevator car can be raised and lowered only to and from the floor, the building unit located on the third floor is the top floor building unit.

In addition, the uppermost building unit provided with the above-mentioned beams has four pillars erected at the four corners and four upper beams which are bridged between the upper ends and the lower ends of these four pillars. And a lower beam, and a pair of reinforcing beams, which are arranged in parallel with each other, are bridged between a pair of upper beams which are arranged to face each other among these four upper beams, and a pulley is attached. It is characterized in that a raised beam is bridged between these reinforcing beams. Further, in this case, a stud may be erected between the pair of upper beams and the lower beam facing the upper beams on both end sides of the pair of reinforcing beams.

It is desirable that a guide rail for guiding the up and down movement of the elevator car is attached to at least one of the studs.

Further, the beam to which such a pulley is attached is made of two steel materials arranged in parallel with each other, and the pulley is preferably arranged between these two steel materials,
The two steels preferably have a vertical web extending along the length of the steel.

[0012]

In the present invention as described above, since the pulley on which the rope for suspending the elevator car is hung is attached to the beam which is a constituent member of the uppermost floor building unit, the conventional steel tower to which the pulley is attached is It becomes unnecessary. This saves the work of building a tower and reduces the cost of the building.

Further, the top floor building unit provided with beams is provided with four columns erected at four corners, and four upper beams and one lower beam which are bridged between upper ends and lower ends of these four columns. In the case of including a beam, a pair of reinforcing beams arranged in parallel to each other are bridged between a pair of upper beams arranged opposite to each other among these four upper beams, and a pulley is attached. The beams are bridged between these reinforcement beams, and studs are reinforced between the pair of upper beams and the lower beams facing these upper beams on both end sides of these reinforcement beams by reinforcing them. It is possible to prevent bending of each upper beam over which the beams are bridged.

When a guide rail for guiding the raising and lowering of the elevator car is attached to at least one of the studs, the stud can be used also as a guide rail attachment member.

Further, a beam to which such a pulley is attached is constructed by including two steel materials arranged in parallel with each other,
When the pulley is arranged between these two steel materials, the rotation shaft of the pulley is bridged over the two steel materials, so that the rotation shaft can be reliably supported at both ends. Further, when these two steel materials have a vertical web extending along the steel material longitudinal direction, the bending strength of the beam with respect to the loading load of the elevator car becomes large, and the reliability and durability of the elevator are increased. improves.
