Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a correction device for correcting a newly added radial member to a normal position when the position of a newly added radial member deviates from a target value in the implementation of a construction method for constructing a large dome roof or the like without support. .
[0002]
[Prior art]
Conventionally, as a construction method for constructing a large roof with no support work, for example, “construction method of large roof” described in JP-A-11-22011 is known. Specifically, after installing the radial member newly added inside the outermost compression ring that constructs the large roof with a crane or the like, the next compression ring is built inside it and the ring-shaped member is sequentially formed. A structure is formed.
[0003]
In the above construction method, when the position of the newly added radial member deviates from the target value, there is no support from the bottom as in the support method, as a means for correcting to the normal position, such as a crane, etc. I had to hang it up and fix it.
[0004]
[Problems to be solved by the present invention]
As described above, if the crane is used for correcting the position of the radial member newly added, the frequency of use of the crane is greatly increased, and the cost is increased accordingly. Further, there are no effective effective correction means and correction devices, such as position correction and fine adjustment, which are very troublesome and require a lot of labor.
[0005]
Therefore, the object of the present invention is not to use a crane or the like for correcting the position of the newly added radial member, and can easily correct the position of the newly added radial member. It is providing the member position correction apparatus which contributes to the improvement of precision and construction efficiency.

Embodiments and Examples of the Invention
The member position correcting device for the construction method for constructing a large roof with no support construction described in claims 1 to 5 is newly added in the implementation of the construction method for constructing a large roof such as a large dome roof with no support construction. When the position of the radial member deviates from the target value, it is preferably implemented as a correction device that corrects the position to the normal position.
[0012]
FIG. 1 shows an embodiment of the invention described in claim 1. This member position correcting device includes a moving mechanism 1 that moves along the existing radial member 11A and takes a reaction force, a support column 2 that stands on the front of the moving mechanism 1, and an upper end portion of the support column 2. The reaction force member 3 connected to the rear portion of the moving mechanism 1, the support member 4 that supports the front portion of the newly added radial member 11B as much as possible, and the support member 4 and the upper end portion of the support column 2 are connected. The cantilever member 5 is provided with an axial expansion / contraction device 6 in the middle of the cantilever member 5.
[0013]
More specifically, as shown in FIG. 1, the moving mechanism 1 moves with the front moving part 1A, the rear moving part 1B, and the moving gantry 1C along the upper flange portion of the existing radial member 11A and reliably. It is configured to take reaction force. The support column 2 stands vertically on the upper surface of the front portion of the movable gantry 1C, and the rear end portion of the reaction force member 3 is connected to the rear portion of the movable gantry 1C.
[0014]
For the existing radial member 11A and the newly added radial member 11B, H-shaped steel is usually used.
[0015]
The existing radial member 11 </ b> A and the newly added radial member 11 </ b> B are initially temporarily joined, and are supported by the cantilever material 5 via the support 4. The cantilever material 5 is firmly supported at a predetermined angle by a cheek cane 7 provided between the cantilever member 2 and the support column 2 (invention of claim 4).
[0016]
The support force of the newly added radial member 11 </ b> B is given by the cantilever material 5 that supports the support 4 and the cheek cane 7. The reaction force is given by the moving mechanism 1 and the support column 2 and the reaction force member 3 assembled in a right triangle shape, and the reaction force is eventually applied to the existing radial member 11A.
[0017]
By the expansion / contraction operation of the expansion / contraction device 6 installed in the middle portion of the cantilever material 5, the newly added radial member 11B is moved up and down to be corrected to a normal position.
[0018]
For the telescopic device 6, a linear drive actuator such as a hydraulic jack or a motor-driven screw jack is preferably used.
[0019]
2A to 2D, the position correction of the newly added radial member 11B is completed, and the moving mechanism 1 moves forward from the existing radial member 11A to the newly added radial member 11B. The procedure to proceed with the construction of a large roof is shown.
[0020]
FIG. 2 (A) shows that a new radial direction member 11C is added and temporarily joined to the end of the radial direction member 11B whose position has been corrected, and a compression ring 8C is installed at the front end portion of the radial direction member 11B. The stage which the support tool 4 left | separated from the member 11B is shown. Thus, in order to correct the position of the new radial member 11C, the member position correcting device moves forward onto the radial member 11B (FIGS. 2B and 2C).
[0021]
The movement of the member position correcting device is performed manually or using power of a roller motor drive or a jack which will be described later.
[0022]
FIG. 2 (D) shows that the member position correcting device is moved forward over the target radial member 11B, the support 4 grasps the front end of the new radial member 11C, and the position of the radial member 11C is reached. The stage where the correction is ready is shown.
[0023]
By the way, when the member position correcting device moves forward, it is naturally necessary to get over the compression ring 8A at the midway position. FIG. 3 and FIG. 4 show an example of a configuration in which the moving mechanism 1 moves over the compression ring 8A.
[0024]
That is, the front side moving part 1A and the rear side moving part 1B are provided with roller groups 10A and 10B that sandwich the upper and lower surfaces of the flange 21 of the existing radial member 11A, and it is possible to ensure movement and reaction force transmitted through the flange 21. It is made into the composition. In addition, the roller group 10B that sandwiches the lower surface of the flange 21 includes a roller support member 1D that allows the lower roller group 10B to be detached from and attached to the flange 21 in both the front moving unit 1A and the rear moving unit 1B. (The invention of claim 5).
[0025]
FIG. 4 shows that when the front side moving portion 1A of the moving mechanism 1 shown in FIG. 2B gets over the compression ring 8A, the lower roller group 10B is detached from the lower surface of the flange 21 by the rotation of the roller support member 1D. An embodiment of a configuration that moves only by the upper roller group 10A and does not cause interference with the compression ring 8A is shown. Even if the lower roller group 10B of the front moving part 1A is detached from the lower surface of the flange 21, the roller groups 10A and 10B of the rear moving part 1B still hold the upper and lower surfaces of the flange 21 as shown in FIG. Therefore, it is possible to move forward on the existing radial member 11A stably.
[0026]
Next, when the rear side moving part 1B gets over the compression ring 8A, the front side moving part 1A that has already got over the compression ring 8A has the roller groups 10A and 10B sandwiching the upper and lower surfaces of the flange 21 as shown in FIG. Because it has, it can still move in a stable state.
[0027]
In the state shown in FIG. 2D, the new radial member 11C temporarily joined to the distal end portion of the radial member 11B is moved up and down by the expansion and contraction operation of the expansion and contraction device 6 to be corrected to a normal position. .
[0028]
The steps described above can be repeated sequentially to build the ring-shaped large roof sequentially and efficiently with high accuracy.
[0029]
Note that the correction of the member position is not necessarily performed for all the new radial members 11C, and the member position correction device may be arranged systematically for the entire ring-shaped roof.
[0030]
Moreover, the said moving mechanism 1 should just be the structure which can move stably on the existing radial direction member, and is not restricted to the structure of the structure form shown in FIG.
[0031]
The above-described member position correcting device has a simple structure and is practical, and does not require the use of a crane for correcting the position of the newly added radial member 11C, thereby contributing to cost reduction. Moreover, since it can be finely adjusted by the drive control of the expansion and contraction device 6 provided in the member position correcting device, the position correction of the newly added radial member 11C can be performed easily and with high accuracy, and the accuracy and construction efficiency of the large roof shape can be improved. Contributes to improvement. Moreover, since the said member position correction apparatus moves on the existing radial direction member stably by the moving mechanism 1, and performs position correction, it is highly safe and contributes also to shortening of a construction period.
[0032]
Next, FIG. 5 shows an embodiment of a member position correcting apparatus according to the invention of claim 2. This is substantially the same configuration as the member position correcting device of the embodiment of FIG. 1 described above, but the telescopic device 6 is installed not on the cantilever material 5 but on the reaction material 3. For this purpose, the moving mechanism 1 and the support 2 standing at the front thereof are connected by pins 12 and both ends of the reaction material 3 connecting the rear part of the moving mechanism 1 and the upper end of the support 2 are also pinned. 12, and further, both ends of the cantilever material 5 that connects the support 4 that supports the front part of the newly added radial member and the upper end of the column 2 are also connected by pins 12. Yes. Therefore, when the expansion / contraction device 6 expands / contracts, the column 2 is tilted back and forth in the radial direction, and the support 4 can correct the position of the new radial member via the cantilever material 5.
[0033]
FIG. 6 shows an embodiment of a member position correcting device according to the invention of claim 3. This includes a moving mechanism 1 that moves along an existing radial member and takes a reaction force, a support column 2 that stands vertically at the front of the moving mechanism 1, and a winch that is installed at the rear of the moving mechanism 1. 14 and a support 4 that supports a newly added radial member and a wire 13 that connects the support 4 and the winch 14 via a pulley 15 provided at the upper end of the support column 2. Has been.
[0034]
In this member position correcting device, the position of the new radial member can be corrected by moving the support 4 up and down by the wire 13 wound up or drawn out by the winch 14.
