Problems to be solved by the invention
The columns are welded to building beams having both ends separated vertically, respectively, and laid in the hoistway in 2 rows in the longitudinal direction of the building beams in the vertical direction. In this case, after the refractory covering material covering the shaft wall between the vertically separated building beams is peeled off and the column is laid, the refractory covering material must be covered on the shaft wall, which causes a problem of a large load for laying the column.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a renewal method of an elevator and an elevator, which can reduce the amount of peeling of a refractory covering material and reduce the installation load of a column.
Means for solving the problems
In the method for updating an elevator according to the present invention, the elevator includes: a framework structure which is formed by connecting nodes of a plurality of frame members by building columns and assembling the frame members in the vertical direction, wherein the frame members are formed by assembling building beams into a square shape, and the framework structure is arranged in a hoistway; and a refractory covering material covering a wall of the hoistway, wherein the method for modernizing the elevator includes the steps of: spalling the refractory covering material around the node; erecting a connecting part between the building beams vertical to the nodes, and fixing the connecting part to the building beams; and disposing a column between the connecting members facing each other in the vertical direction, and fixing the column to the connecting members.
Effects of the invention
According to the present invention, only the refractory covering material around the nodes is peeled off before the columns are laid, and therefore the amount of peeling of the refractory covering material is reduced. Therefore, the work load for peeling the refractory covering material and the work load for re-spraying the refractory covering material are reduced, and the load for laying the column is reduced.

Detailed Description
Fig. 1 is a schematic view showing a framework structure installed in a hoistway of an elevator according to embodiment 1 of the present invention, fig. 2 is a perspective view of a main part showing a state in which a refractory covering is partially removed in an elevator modernization method according to embodiment 1 of the present invention, fig. 3 is a perspective view of a main part showing a state in which a connection member is attached in an elevator modernization method according to embodiment 1 of the present invention, fig. 4 is a view of a state in which a column is attached in an elevator modernization method according to embodiment 1 of the present invention, viewed from above in a vertical direction, and fig. 5 is a view of a state in which a column is attached in an elevator modernization method according to embodiment 1 of the present invention, viewed from a horizontal direction. In fig. 1, for convenience, only a part of the refractory covering is illustrated.
In fig. 1, a frame structure 100 is formed by assembling a plurality of frame members 10 in the vertical direction, i.e., the vertical direction, by connecting nodes of the frame members 10 to each other by linear building columns 12, and the frame members 10 are formed by assembling 4 linear building beams 11 in a square shape. The joint of the frame member 10 is formed by abutting an end face of one of the building beams 11 against a side face of an end portion of the other building beam 11 and rigidly joining the two by welding or the like. Further, the nodes of the frame member 10 are rigidly joined to the building columns 12 by welding or the like.
The framework structure 100 configured as described above is fixed to the floor of a pit of a hoistway, for example, and laid in the hoistway in the vertical direction. The building columns 12 are located at four corners in the hoistway and extend in the vertical direction. The wall of the hoistway is covered with a refractory cover material 4 which is a refractory material. In fig. 1, the frame structure 100 is configured by overlapping 4 sections of the frame members 10 via the building columns 12, but actually, the frame members 10 are overlapped in a plurality of sections so as to have the same height as the entire length of the hoistway in the vertical direction.
Next, a method of updating the elevator configured as described above will be described.
First, as shown in fig. 2, the refractory covering material 4 around the joint of the frame member 10 is peeled off to expose the upper surface of the building beam 11 around the joint. Next, as shown in fig. 3, a connecting member 20 made of, for example, H-shaped steel is erected between the building beams 11 vertical at the node point, and is fixed to the building beams 11 by welding, fastening with bolts, or the like. Thereby, the connecting member 20 is horizontally erected between the upper portions of the building beams 11 in the vicinity of the respective nodes.
Next, as shown in fig. 4 and 5, for example, the upright 13 made of H-shaped steel is disposed between the vertically separated connecting members 20, and the end portion of the upright 13 is fixed to the connecting member 20 by welding, fastening with a bolt, or the like. Thus, the columns 13 are laid in a row in the vertical direction at each of the four corners of the skeletal structure 100.
Next, although not shown, a flame retardant material is sprayed on the portion where the refractory covering material 4 is peeled off, and the wall 2 of the hoistway 1 is covered with the refractory covering material 4. Thereafter, although not shown, a new rail is carried in, and the rail is fixed to the column 13 using a bracket. Then, a necessary updating operation is performed such as attaching a new hoisting machine to the machine room and attaching a new car and a new counterweight to the hoistway.
Here, for comparison, a method of attaching the conventional column 13 will be described with reference to fig. 12.
First, the refractory coating material 4 coated on the wall 2 of the hoistway 1 between the vertically separated building beams 11 is peeled off, and the column 13 is disposed between the vertically separated building beams 11. Subsequently, both end portions of the column 13 are welded to the building beams 11, and are fixed by fastening with bolts or the like. Therefore, as shown in fig. 12, 2 columns 13 are disposed between the building beams 11 so as to be separated in the longitudinal direction of the building beams 11. Similarly, 2 columns 13 are disposed between the building beams 11 separated in the vertical direction. Thus, the columns 13 are laid on the respective opposite wall surfaces of the hoistway so as to extend in the vertical direction in 2 rows in the longitudinal direction of the building beam 11, and the guide rails are attached to the columns 13 via brackets.
Thus, in the conventional method of attaching the column 13, the peeling amount of the refractory coating material 4 increases, and therefore the peeling work load of the refractory coating material 4 and the re-spraying work load of the refractory coating material 4 increase, and the installation load of the column 13 increases.
According to embodiment 1, since only the refractory covering material 4 near the node where the column 13 is installed is peeled off before the column 13 is laid, the peeling work load of the refractory covering material 4 and the re-spraying work load of the refractory covering material 4 can be reduced, and the laying load of the column 13 can be greatly reduced.
Further, since the pillars 13 are laid at dead corners in the hoistway 1, that is, at four corners of the frame structure 100, interference with equipment of the elevator can be avoided.
In addition, in embodiment 1 described above, the node of the frame member 10 is configured by abutting the end face of one building beam 11 against the side face of the end portion of the other building beam 11 and rigidly joining them by welding or the like, but the node of the frame member may be configured by, for example, forming the end face of the building beam 11 as an inclined face inclined at 45 ° with respect to the longitudinal direction of the building beam 11, abutting the end faces of the building beams 11 against each other and rigidly joining them by welding or the like.
Fig. 6 is a perspective view showing a connecting member used in an elevator modernization method according to embodiment 2 of the present invention, and fig. 7 is a perspective view of a main portion showing a state in which a column is attached in an elevator modernization method according to embodiment 1 of the present invention.
In fig. 6, the connecting member 21 is formed by making a thick metal plate or a thick metal block into an L-shape.
As shown in fig. 7, the connecting member 21 thus constructed is erected between the upper portions of the building beams 11 perpendicular to the nodes where the refractory covering material 4 is peeled off, and is fixed to the building beams 11 by welding, fastening with bolts, or the like. At this time, the building column 12 contacts the inner peripheral surface of the L-shaped connecting member 21. The upright column 13 is laid between the vertically separated connecting members 21 by fixing both end portions thereof to the upper and lower surfaces of the vertically separated connecting members 21 by welding, fastening with bolts, or the like.
Therefore, also in embodiment 2, the same effects as those in embodiment 1 can be obtained.
In embodiment 2, the building column 12 is in contact with the inner peripheral surface of the L-shaped connecting member 21, and therefore the joining strength of the connecting member 21 is improved.
Embodiment 3
Fig. 8 is a perspective view of a main part showing a state before attachment of a connecting member in an elevator modernization method according to embodiment 3 of the present invention, and fig. 9 is a perspective view showing a connecting member used in an elevator modernization method according to embodiment 3 of the present invention.
In fig. 8, the joint of the frame member 10A is formed by overlapping the end of one building beam 11 on the end of the other building beam 11 and rigidly joining the two by welding or the like. As shown in fig. 9, the connection member 22 includes: an L-shaped support member 23 made of a thick metal plate or a metal block; and a height adjuster 24 that is made of H-shaped steel similar to the building beam 11 into a short bar shape, has the same height as the building beam 11, and is rigidly joined to one lower surface of the L-shaped support member 23 by welding or the like.
In embodiment 3, as in embodiment 2, the connecting member 22 is installed between the upper portions of the building beams 11 perpendicular to the nodes where the refractory covering material 4 is peeled off. At this time, the support member 23 is placed on the end of one of the building beams 11, and the height adjuster 24 is placed on the end of the other building beam 11. Thereby, the support member 23 is horizontally erected between the building beams 11. Then, the support member 23 and the height adjuster 24 are fixed to the building beam 11 by welding, fastening with bolts, or the like. The construction column 12 is in contact with the inner peripheral surface of the L-shaped support member 23. The upright column 13 is laid between the vertically separated connecting members 22 by fixing both end portions thereof to the upper and lower surfaces of the support members 23 of the vertically separated connecting members 22 by welding, fastening with bolts, or the like.
Therefore, also in embodiment 3, the same effects as those in embodiment 2 can be obtained.
In embodiment 3, the connection member 22 is configured by the L-shaped support member 23 and the height adjuster 34, but the linear connection member 20 in embodiment 1 may be used as the support member instead of the L-shaped support member 23.
Fig. 10 is a perspective view showing a connecting member used in an elevator modernization method according to embodiment 4 of the present invention, and fig. 11 is a view showing a state where the connecting member is mounted in the elevator modernization method according to embodiment 4 of the present invention, as viewed from vertically above.
In fig. 10, the connection member 25 includes: a pair of support members 26, which are respectively configured in the same manner as the connecting members 20 and are arranged in parallel with each other while being separated in the height direction, and a connecting member 27, which is made of an angular steel pipe, has a length in the same manner as the height of the building beam 11, is disposed in the center of the support members 26 between the pair of support members 26 in the length direction thereof so that the length direction thereof is perpendicular to the length direction of the support members 26, and is rigidly joined to each of the support members 26 by welding.
As shown in fig. 11, the connecting member 25 is erected between the vertical building beams 11 at the node where the refractory covering material 4 is peeled off. At this time, the pair of support members 26 are placed so as to sandwich the end portions of the two building beams 11 perpendicular at the node point in the vertical direction. Further, the side surfaces of the upper and lower sides of the two building beams 11 perpendicular at the node point, which face the inside of the hoistway 1, are in contact with the coupling member 27. Thereby, the support member 26 is horizontally erected between the building beams 11. The support member 26 is fixed to the building beam 11 by welding, fastening with bolts, or the like. The column (not shown) is laid between the vertically separated connecting members 25 by fixing both end portions thereof to the support members 26 of the vertically separated connecting members 25 by welding, fastening with bolts, or the like.
Therefore, also in embodiment 4, the same effects as those in embodiment 1 can be obtained.
In embodiment 4, the building beam 11 and the connecting member 27 are in contact with each other, and therefore the joining strength of the connecting member 25 is improved.
In embodiment 4, the connecting members in embodiment 1 are installed between the upper portions and the lower portions of the building beams vertical at the nodes so as to face each other in the vertical direction, and the connecting members facing each other in the vertical direction are connected by the connecting members, but the connecting members in embodiments 2 and 3 may be installed between the upper portions and the lower portions of the building beams vertical at the nodes so as to face each other in the vertical direction. In the case where the L-shaped connecting members according to embodiment 2 are arranged to face each other in the vertical direction, the corners of the L-shaped connecting members facing each other in the vertical direction may be connected to each other by the connecting member. In the case where the connecting members of the L-shaped support members and the height adjusting members in embodiment 3 are arranged to face each other in the vertical direction, the corners of the L-shaped support members facing each other in the vertical direction may be connected to each other by the connecting members.
In the above embodiments, the elevator in which the wall of the hoistway is covered with the refractory covering material has been described, but the present invention can be applied to an elevator in which the wall of the hoistway is covered with a refractory material such as mortar, a sound insulator, or a gypsum board, and can obtain the same effects.
