Description

  The present invention relates to a method for constructing a roof frame.

  Patent Document 1 discloses a technique related to an intermediate-layer steel frame traveling construction method. In this prior art, one unit of an intermediate-layer steel truss that is grounded is placed between both beams at a predetermined depth position from the side of the housing wife, and then after the completion of grounding of the same unit, this is the same as the predetermined front position. And the two units are connected by a girder beam to form a block. Then, slide for one span of the block and add units sequentially to form a large-scale block, then slide under the roof truss and finally fix.

  Here, a slide construction method may be employed to construct a roof frame that is built on a frame of a structure having a wide space inside an arena or a gymnasium. In the slide method, a number of frame units that make up the roof frame are assembled on a work floor that is easy to work in advance, one frame unit at a time, and then each frame unit is placed on the running rail and slides from one side to the other. This is a method of assembling the entire roof frame.

  However, in the case of this slide method, the roof frame is fixed to the frame until the first frame unit assembled first reaches the other end of the frame, that is, until all the frame units constituting the roof frame are completed and connected. The construction cannot be performed. Therefore, it is desired to fix the roof frame to the frame at an early stage and shorten the construction period.

A construction method for a roof frame according to an embodiment of the present invention will be described. In each figure, the vertical direction is indicated by an arrow Z, and two directions perpendicular to the horizontal direction are indicated by an arrow X and an arrow Y. In each drawing, the right side in the X direction is one side and the left side is the other side. 1 to 6 show a vertical cross section of the structure, but hatched lines indicating the cross section only show the stand in order to avoid complication of the drawing.

[Construction]
First, the structure of the structure in which the roof frame is constructed by the construction method of the present embodiment will be described.

  As shown in FIGS. 6 and 7, the structure 10 according to the present embodiment is a so-called arena whose outer periphery or substantially outer periphery is surrounded by an inclined stepped stand 20 as an example of a housing. In addition, the inner side surrounded by the stand 20 is an arena floor 12 (see FIG. 6) for performing a game.

  A roof frame 100 constituting the roof 14 of the structure 10 is installed on the upper end 22 of the stand 20. Reference numeral 20 </ b> A is one side portion constituting one half of the stand 20, and reference numeral 20 </ b> B is the other side portion constituting the other half of the stand 20. Reference numeral 22A denotes an upper end portion of the other end of the one side portion 20A of the stand 20, and reference numeral 22B denotes an upper end portion of the other end portion 20B of the stand 20.

  The roof frame 100 has a structure in which a plurality of frame units 110 whose longitudinal direction is the Y direction are joined in the X direction. Note that a diagonal member may be provided on the frame unit 110 to form a truss structure. Further, as will be described later, the roof frame 100 is divided into a leading frame block 120 that constitutes the other half and a subsequent frame block 130 that constitutes the one half, and these are joined at the central joint 125. Have been integrated.

[Construction method]
Next, an example of the construction method of the roof frame 100 installed in the upper end part 22 of the stand 20 of the structure 10 of this embodiment is demonstrated.

  As shown in FIG. 1, one side 20A of the stand 20 is constructed. Further, the temporary work stage 200 is assembled adjacent to the outside of the one side portion 20A of the stand 20.

  As shown in FIG. 2, the material is lifted by the crane 300 and the frame unit 110 is assembled on the work stage 200, and the preceding frame block 120 (see also FIGS. 6 and 7) constituting the other half of the roof frame 100. Make it. At the same time, the other side 20B of the stand 20 is constructed.

  As shown in FIG. 3, the rail 150 is installed between the upper end 22A of the one side 20A of the stand 20 and the upper end 22B of the other side 20B, and the preceding frame block 120 on the other side, which has been manufactured, Place on rail 150 and slide to the other side. Note that one side of the rail 150 is supported by a temporary support column 210.

  As shown in FIG. 3 and FIG. 4, work is performed to fix the preceding frame block 120 moved to the other side to the other side portion 20B of the stand 20, and at the same time, the frame unit 110 is assembled on the work stage 200, and the roof The succeeding frame block 130 (see also FIGS. 6 and 7) constituting the other half of the frame 100 is produced.

  As shown in FIG. 5, when the production of the trailing frame block 130 on one side is completed, it is placed on the rail 150 and slid to the other side. Then, a work or the like for fixing to the one side portion 20A of the stand 20 is performed, and the leading frame block 120 and the trailing frame block 130 are integrated by bonding at the central bonding portion 125.

  As shown in FIG. 6, the rail 150, the temporary work stage 200, and the temporary support column 210 are removed, and other construction is performed to complete the structure 10.

  Although not described, other construction is performed simultaneously with the construction work of the roof frame 100.

[Action and effect]
Next, the operation and effect of this embodiment will be described.

  The preceding frame block 120 produced on the work stage 200 temporarily installed on the outside of the one side 20A of the stand 20 of the structure 10 is replaced with the upper end 22A of the one side 20A of the stand 20 and the upper end 22B of the other side 20B. And is slid to the other side and fixed to the other side portion 20B of the stand 20.

  Therefore, before the assembly of the entire roof frame 100 is completed, it is possible to carry out construction and the like for fixing the preceding frame block 120 to the other side 20B of the stand 20 at an early stage, and at the same time, manufacture the trailing frame block 130. It can be performed.

  Therefore, the roof frame 10 can be fixed to the stand 20 earlier than in the case where the work for fixing to the stand 20 cannot be performed until the entire roof frame 100 is completed as in the conventional slide method. Therefore, since the construction of the outer wall and the like to be engaged with the roof frame 100 can be started at an early stage, the construction can be progressed efficiently. As a result, the construction period for constructing the structure 10 is shortened.

<Others>
The present invention is not limited to the above embodiment.

  For example, in the above-described embodiment, the structure 10 is a so-called arena whose outer periphery or substantially outer periphery is surrounded by an inclined stepped stand 20, but is not limited thereto. For example, the structure may be a warehouse or a gymnasium having a wide space with no pillars or almost no pillars inside.

  Further, for example, in the structure 10 of the above embodiment, the rail 150 on which the leading frame block 120 and the trailing frame block 130 are slid is removed after the construction of the roof frame 100 is completed. However, the rail 150 may be left as it is without being removed.

  Further, for example, in the above embodiment, the roof frame 100 has a flat shape, but may have a curved and complicated structure. In the case of a complicated structure in which the roof frame 100 is curved, each frame unit 110 has a different structure. When the roof frame 100 is sequentially connected and slid as in the conventional slide method, deformation and distortion are likely to occur. However, when the present invention is applied, it is possible to adjust deformation, strain, and the like when joining and integrating at the central joint 125 by dividing the left and right symmetric leading frame block 120 and trailing frame block 130. This is preferable because it is possible.

  Further, for example, in the above embodiment, the roof frame 100 is divided into the preceding frame block 120 and the subsequent frame block 130, but the present invention is not limited to this. The roof frame 100 may be divided into three or more frame blocks.

  Moreover, it cannot be overemphasized that it can implement with a various aspect in the range which does not deviate from the summary of this invention.
