Abstract

PROBLEM TO BE SOLVED: To simplify construction, promote safety, reduce a construction cost and to shorten a construction period by raising and lowering and moving the peripheral surface of a building by a rising and falling section and a peripheral surface curing member with a driving unit while holding a proper position with an induction n member, and successively curing the peripheral surface of a story before the installation of an exterior wall or before the construction. SOLUTION: A driving unit 21 is replaced from steel framed beam B in (n) floor to steel framed beam B in (n+1) floor, and an induction member 23 is also installed to steel framed beam B in (n+2) floor. Then, the fixing of a cover 24 to the steel framed beam B in a bracket 24a is released, and when the driving unit 21 is started, since an electric motor 21b and a pinion 21a are rotated, a hook 22a of a rising and falling section 22 is raised, and when the cover 24 and a peripheral surface curing member 10 is raised, a guide post 22b precedently passes through a rack guide 23a, and since it is guided at two or more positions, the peripheral surface curing member 10 can be safely raised even if it is hit by strong wind. Accordingly, simplification of construction, reduction of construction cost and promotion of safety can be accomplished.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sequentially curing the outer peripheral surface of a floor before the installation or construction of an outer wall in a construction work, and is particularly useful in the construction work of a high-rise building.

[0002]

2. Description of the Related Art Conventionally, in the construction work of a high-rise building or the like, for example, an outer peripheral surface of a floor on which an outer wall is not installed or constructed, such as a floor on which a steel frame is preceded and a curtain wall is not yet mounted. As a means of curing, drop a curing net from the upper floor of the steel frame built,
Some of them are fixed to the lower floor using a rope or the like, and some are fixed to a temporary bracket or the like attached to a column or a beam using a bolt or a nut, and an outer peripheral curing frame having a curing net stretched over a frame body.

[0003]

However, such peripheral curing means has the following problems. In the case of outer peripheral curing using a curing net, it is necessary for workers to perform rope bundling work on the upper floor at the time of installation, and when installing or constructing the outer wall of the lower floor, turn over the curing net on that floor and place it on the upper floor. It has to be retied, which is troublesome and dangerous. In addition, the tied curing net may be dislodged by strong winds, and it lacks safety and does not look good.
On the other hand, the outer peripheral curing using the outer peripheral curing frame requires a tower crane to replace the outer peripheral curing frame, and the tower crane is restrained each time, which hinders the process and increases costs.

As an example of means for solving the above problems,
A self-moving outer peripheral curing device described in Japanese Patent Application No. 9-120669 by the present applicant is exemplified. This is a device for sequentially curing the outer peripheral surface of a floor before installation or construction of an outer wall in a construction work, and includes an upper and lower guide member having fixing means detachable from a structural shaft assembly, and an attachment and detachment of the structural shaft assembly. An outer peripheral surface curing member guided by the upper and lower guide members, and an elevating means for connecting the upper and lower guide members and the outer peripheral surface curing member to raise and lower one relative to the other; And a power source for supplying power to the lifting / lowering means.

In the self-moving outer peripheral curing device,
Elevating means powered by a power source sequentially raises and lowers the vertical guide member and the outer peripheral curing member, and the device itself moves and moves like a so-called scale insect, and the outer periphery of the floor before the outer wall is installed or before the construction. Since the surface can be cured sequentially, it can be replaced safely without the need for troublesome work and tower cranes, the curing range is wide, it can be securely fixed to the frame, and it can provide a good-looking one It can contribute to simplification of construction, improvement of safety, improvement of aesthetics, reduction of construction cost, and shortening of construction period. On the other hand, in the present invention, the problem to be solved is the same as that of the self-moving outer peripheral curing device, and another means for solving the problem is provided.

[0006]

That is, the present invention relates to an apparatus for sequentially curing the outer peripheral surface of a floor before the installation or construction of an outer wall in a construction work, and comprises an outer peripheral curing member and a vertical curing member. A lifting unit, comprising a pinion and a mechanism for rotating the pinion, a drive unit detachably fixed to the structural shaft assembly,
A rack that meshes with the pinion, a guide column fixed to the rack, a lifting unit that is raised and lowered by the drive unit, an annular portion through which the guide column is inserted, and a fall prevention mechanism for the guide column. A guide member that is detachably fixed to a structural shaft assembly and guides the elevating unit to an appropriate position; and a drive unit, an elevating unit, and detachably fixed to a structural shaft assembly and fixed to the guide column. And a panel-shaped cover for covering the guide member. With this configuration, the present invention provides a lifting unit that is raised and lowered by the drive unit and an outer peripheral surface curing member fixed to the lifting unit that moves up and down on the outer peripheral surface of the building while maintaining an appropriate position by the guide member. Thus, the apparatus can sequentially cure the outer peripheral surface of the floor before installation or construction of the outer wall.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. In addition, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

[0008] 1. Configuration (1) Overall Configuration FIG. 2 is an external perspective view showing an embodiment of a self-elevating type outer peripheral curing device according to the present invention. Reference numerals B and C denote a steel beam and a steel column, respectively, which constitute a structural axis. P indicates a curtain wall as an outer wall. In FIG. 1, the self-elevating type outer peripheral curing device 1 includes an outer peripheral surface curing member 10 and an elevating means 20 for moving the outer peripheral surface curing member 10 up and down. 3 and 4 show a cross-sectional view and a vertical cross-sectional view of the self-elevating type outer peripheral curing device 1. Here, the outer surface curing member 1
Numeral 0 is composed of a steel frame 11 and a mesh sheet 12 stretched between the steel frames 11, and directly covers the outer peripheral surface of the floor to be cured, and is fixed integrally with the cover 24 as described later. . Note that the configuration of the outer peripheral surface curing member 10 is not limited to the above, and is appropriately determined in consideration of performance such as strength and lightness, aesthetic appearance, and the like. The elevating means 20 is
It comprises a drive unit 21, a lifting unit 22, a guide member 23, and a cover 24. Hereinafter, these will be described in detail.

(2) Configuration of Each Part 2-1) Drive Unit 21 As shown in FIGS. 5 and 6, the drive unit 21 includes a pinion 21a, an electric motor 21b which is a mechanism for rotating the pinion 21a, and a battery (not shown). And a unit cover 21c that is a bearing for the pinion 21a and also functions as an outer shell. Further, it is desirable that the auxiliary guide roller 21d is fixed to the unit cover 21c, and plays a role of suppressing the swing of the guide support 22b described later when the guide support 22b moves up and down. This drive unit 2
1 can be repositioned on the steel beam B by a tower crane or manually when the self-elevating outer peripheral curing device 1 is raised and lowered. Here, the electric motor 21b and a battery (not shown) are selected as the mechanism for rotating the pinion 21a, but a portable external power such as an impact wrench may be used.

2-2) Elevating part 22 The elevating part 22 is a rack 2 which meshes with the pinion 21a.
2a and a guide post 22b integrally fixed to the rack 22a. The drive unit 21 transmits the power and moves up and down. The outer peripheral surface curing member 10 is integrally fixed to the guide column 22b via a cover 24 described later. FIGS. 5 and 6 show these. As is clear from the above figure, the rack 22a is connected to the pinion 21a of the drive unit 21.
And move up and down with its rotation. The guide post 22b is an H-shaped steel fixed integrally with the rack 22a. The guide post 22b is guided by a guide member 23 to be described later to move up and down, so that the elevating portion 22 and the cover 24 The outer peripheral surface curing member 10 can be moved up and down without shaking.

2-3) Guide member 23 As shown in FIGS. 7 to 9, the guide member 23 includes a wrapper guide 23a, a bracket 23b, and a detent 23c.
And a ratchet mechanism.
The wrapper guide 23a is an annular portion through which the guide column 22b is inserted, and plays a role of guiding the elevating unit 22 to an appropriate position. As shown in FIG. 7, the wrapper guide 23a has a shape that clamps the ends of the flanges of the guide posts 22b, and the right and left wrapper guides 23a increase the stability of the guide posts 22b when ascending and descending. Bracket 23b
Is a portion for manually fixing the guide member 23 to the steel beam B serving as a structural frame, and for fixing the bolt to the steel beam B using a clip (not shown) or the like. . FIG. 9 is a cross-sectional view taken along the line AA in FIG. 7, and shows a ratchet mechanism having the detent 23c in FIG. This ratchet mechanism is a mechanism for preventing the guide column 22b from falling, which is an essential component in the present invention. In this case, the flange end of the guide column 22b is formed in a feed dog shape. The detent 23c forms a ratchet mechanism. By configuring the guide post 22b and the wrapper guide 23a in this way,
The guide post 22b serves as a safety stopper when the guide post 22b passes through the inside of the wrapper guide 23a, and prevents the guide post 22b from being dropped by any chance.

2-4) Cover 24 As shown in FIG. 2, the cover 24 is formed by bending a panel made of steel or aluminum, and is manually and detachably fixed to a steel beam B as a structural frame. (See FIG. 3). The bracket 24a is effective when the load of the lifting unit 22, the cover 24, and the outer peripheral surface curing member 10 cannot be stored in the drive unit 21, such as during the replacement of the drive unit 21. The bracket 24a is fixed to the steel beam B, and the loads of the elevating part 22, the cover 24 and the outer peripheral surface curing member 10 are deposited. The essential role of the cover 24 is to shield the drive unit 21, the elevating part 22, and the guide member 23 having various shapes from the external line of sight, thereby contributing to the improvement of the aesthetic appearance. Therefore, it is desirable to devise an appropriate pattern or the like on the surface of the cover 24 so as to make the design beautiful. Further, since the cover 24 also serves to connect the outer peripheral surface curing members 10, the outer peripheral surface of the building under construction is naturally directly cured.

(3) Others The drive unit 21, the elevating unit 22, the guide member 23, and the cover 24 described above are not limited to the above-mentioned shapes and the like. Can be used. In addition, the pinion 21a of the drive unit 21 is moved in the opposite direction (therefore, the electric motor 21).
By rotating b in the opposite direction, it is possible not only to rise but also to descend. However, in that case, FIG.
It is necessary to keep the ratchet mechanism as shown in FIG. Further, the self-elevating outer peripheral curing device 1 according to the present invention.
Is the elevating unit 22 (rack 22a and guide support 22b)
By making the length of the space sufficiently large, the present invention can be applied to buildings having different floor heights for each floor. As is clear from this, the self-elevating type outer peripheral curing device 1 according to the present invention includes an outer peripheral surface curing member 10 that is not versatile because it is necessary to appropriately determine dimensions according to floor height and span.
It is composed of versatile lifting and lowering means 20 that can be used in almost all construction work because it is not affected by floor height or span. Can be diverted to construction work.

2. Procedure for using the self-elevating outer peripheral curing device 1 Next, the procedure for using the self-elevating outer peripheral curing device 1 according to the present invention thus configured will be described with reference to FIG. FIG. 1 shows that the self-elevating type outer peripheral curing device 1 has n floors and n floors.
It is a side view showing the state fixed to the steel beam B of the + 1st floor. Here, the curtain wall P has been installed up to the n-2 floor, and the curing target floors are the n-1 floor, the n floor, and the n + 1 floor. Subsequently, when the curtain wall P is installed on the (n−1) th floor, the self-elevating outer peripheral curing device 1 according to the present invention is used.
Is raised in the following procedure.

First, the drive unit 21 is changed from the steel beam B on the nth floor to the steel beam B on the (n + 1) th floor by a tower crane or manually. Further, the guide member 23 is also installed on the steel beam B on the (n + 2) th floor. The guide member 23 may be fixed to the steel beam B on the ground in advance when constructing the steel frame. This completes the preparation before the self-elevating type outer peripheral curing device 1 is raised (FIG. 1).
reference). Next, the fixing of the cover 24 to the steel beam B at the bracket 24a is released, and the drive unit 21 is activated. Then, the electric motor 21b rotates in the direction of the arrow shown in FIG. 6, and therefore the pinion 21a also rotates in the direction of the arrow in FIG. 6, so that the rack 22a of the elevating unit 22 meshing with the pinion 21a rises. Become. At this time, the auxiliary guide roller 21d is also rotating in the direction of the arrow. With the rise of the rack 22a, the guide column 22b fixed integrally with the rack 22a, and thus the cover 24 and the outer peripheral surface curing member 10 fixed to the guide column 22b, rise on the outer periphery of the building (see FIG. 1).

Then, the guide post 22b and thus the cover 2
As shown in FIGS. 7 and 8, when the outer surface curing member 4 and the outer peripheral surface curing member 10 are lifted, the guide column 22b always passes through the wrapper guide 23a of the guide member 23 previously attached to the steel beam B. In addition, since the outer peripheral surface curing member 10 is guided by at least two places, the outer peripheral surface curing member 10 can be safely raised without being shaken even if it is hit by a strong wind.

When the guide column 22b, and thus the cover 24 and the outer peripheral surface curing member 10 are raised by one level, the drive unit 21 is stopped and the cover 24 is fixed to the steel beam B at the bracket 24a (FIG. 1).

By repeating the above-described procedure, the self-elevating type outer peripheral curing device 1 can sequentially ascend the outer peripheral surface of the building and sequentially cure the outer peripheral surface of the floor before the installation of the outer wall or the construction. it can. In addition, the pinion 21a is rotated in the opposite direction to the above (therefore, the electric motor 21).
By rotating b in the opposite direction to the previous direction), the self-elevating type outer peripheral curing device 1 can also sequentially descend the outer peripheral surface of the building. In this embodiment, the steel beam B is used as the fixing target of the drive unit 21 and the like.

[0019]

As described above, the self-elevating type outer peripheral curing apparatus according to the present invention is an apparatus for curing the outer peripheral surface of a floor where an outer wall is not installed or constructed in a construction work of a high-rise building or the like. It is configured so that it can be lifted by a simple mechanism without requiring time-consuming work at the time of replacement or unnecessarily constraining a lifting machine such as a tower crane. Peripheral curing can be performed safely at low cost, simplifying construction, reducing construction costs,
Safety can be improved. In addition, the self-elevating type outer peripheral curing device according to the present invention is securely fixed to the structural frame and does not swing due to strong wind, so it is safe and does not require any trouble such as repair. Furthermore, since the appearance of the device is simple, it can contribute to the improvement of aesthetic appearance during construction, and since it is versatile except for the outer surface curing member, the construction cost can be reduced.
