Description

TECHNICAL FIELD The present invention relates to a method for constructing a roof of an outdoor storage that covers an outdoor storage such as wood chips for fuel or coal stacked outdoors, and a roof frame.

When storing wood chips for fuel, coal, etc. (hereinafter referred to as stored materials), there are an outdoor storage system and an indoor storage system. In the case of the indoor storage method, it is usual to build the storage shed first and then store the storage, but the storage of the outdoor storage (hereinafter referred to as the outdoor storage) is kept in that place. As it was, there was a case where a storage shed was constructed later.

Since the outdoor storages are stacked at a predetermined position in the loaded yard at a substantially constant height in a conical shape or a dike shape, the skirt has a considerably wide skirt. Therefore, the storage shed will be the Ohari span frame, but since the shed frame will be constructed with outdoor storages in place, a general construction method that uses supports such as vents cannot be applied.

Therefore, as shown in FIG. 1, temporary slide rails 2 and 2 are laid on both sides of the outdoor storage 1, and the partial frames 3a, 3b of the roof 3 are located near the outdoor storage 1... In some cases, after the entire shed 3 is erected, a slide construction method in which the temporary slide rails 2 and 2 are moved in the direction of the arrow is adopted.

In the case of the slide construction method, it is necessary to structurally stabilize the partial frames 3a, 3b,... Of the shed 3 even during movement, but as shown in FIG. 2, the vertical reaction force is applied to the column bases F, F. In addition to R _V (indicated by a vertical arrow), a horizontal reaction force R _H (indicated by a horizontal arrow) that resists a large horizontal force that causes the column bases F and F to open outward acts. Therefore, in the conventional slide construction method, it was necessary to construct a continuous and strong foundation that can resist the large horizontal force from the column bases F, F over the entire length, so that costs other than the original foundation construction cost There has occurred.

Moreover, since a large horizontal force from the column bases F, F, which try to spread outward, is constantly acting on the temporary slide rails 2, 2, it is necessary to take sufficient safety measures during slide movement. It was

As a method of suppressing the horizontal force of the column bases F, F of the partial frames 3a, 3b,... During the sliding movement, for example, a tension member that horizontally connects the column bases F, F of both columns in the beam direction is provided horizontally. , A method of introducing tension to balance with a large horizontal force to open in the horizontal direction is conceivable. However, since there is the outdoor storage 1, this method cannot be adopted because it interferes with the tension member when the partial frames 3a, 3b,... Move on it.

As prior arts for the sliding method of the Ootari frame, there are Patent Documents 1 and 2, for example. Patent Document 1 discloses that when a multistory building having an arch-shaped frame moves along a rail, the feet of the arch-shaped frame are connected to each other by a connecting member made of a first-story beam, thereby This is a slide method that processes the thrust acting on the feet and eliminates the need for thrust support rails.

In this construction method, since the beam in the lowermost layer (first floor) of the building is treated with thrust, if there is an existing object in the middle of the sliding direction, it interferes with the beam. Therefore, the slide method of Patent Document 1 is based on the premise that there are no obstacles in the slide advancing direction.

Patent Document 2 is a construction method in which a rolling support device is installed on each pillar head of an existing column row, and a roof frame is placed and slid on a beam for movement spanning the rolling support device. A method is disclosed in which the beams are connected to each other by tie bars to suppress the expansion of the roof frame, so that the columns are slid without applying a horizontal force.

In this method, the pillars are already installed before sliding, and the roof frame is installed on it, so even if there are existing objects up to the height of the pillars, the tie bars will interfere with the existing objects during sliding. This is not the case, but it is not applicable when there is an existing object that is higher than the height of the tie bar.

Therefore, in the prior arts disclosed in Patent Documents 1 and 2, in the method of sliding the roof covering the existing thing that is stored outdoors with the pillar and the roof frame integrally (see FIG. 1), the thrust of the pillar base is used. The problem of restraint cannot be solved. Moreover, there is no description suggesting a solution to the problem.

JP-A-6-316975 JP, 9-72004, A

The present invention, in the case where a slide method is used as a method for constructing a shed later while keeping the outdoor storage in its place, a column base during sliding movement of the shed without interfering with the outdoor storage. It is an object of the present invention to provide a method of constructing a roof of an outdoor storage and a roof frame structure thereof that can suppress the horizontal reaction force of a section and reduce the foundation construction cost as compared with the conventional slide method.

The present invention is assembled at a place for assembling a slide rail laid on both sides of an outdoor store and a roof frame of the outdoor store, and slidingly moving on the slide rail to perform the outdoor store. It is an invention of a method of constructing a roof of an outdoor storage, which comprises a plurality of partial frames installed on an article, and is characterized by including the following steps.
(1) A step of laying slide rails across the entire length of both sides of the outdoor stored article.
(2) A step of further extending and laying the slide rails to an assembly site of the roof frame.
(3) At the assembly place of the roof frame, a plurality of pillars that slide on the slide rails on both sides of the outdoor storage, and a plurality of bridges that straddle the outdoor storage between the two pillars. And a beam head of one of the two columns and one beam end of the beam are rigidly joined, and a column head of the other column and the other beam end of the beam A step of assembling a plurality of partial frames in a direction in which the slide rails are laid, in which the joints with the sections are joined to allow rotation to some extent.
(4) A step of installing a tension member between the joints of the column heads of the columns on both sides and the beam end portions of the beams on the partial frame or in the vicinity of the joints (see FIGS. 4 and 5).
In addition, in the partial frame, a portion below the position of the rotation-permissible joint and the rigid joint in a joint state in which rotation is permitted to some extent is referred to as a column, and an upper portion is referred to as a beam.
(5) A step of introducing tension into the tension material to structurally make the partial frame self-supporting.
(6) A step of slidingly moving the self-supporting partial frame on the slide rail to a predetermined position of the outdoor storage.
(7) A step of repeating steps (3) to (6) until the entire outdoor storage or the necessary range thereof is covered.
(8) After all the slide movement steps of the partial frame are completed, an insertion member for fixing the rotation of the rotation-allowed joint is attached to the joint between the column head and the beam end on the side where the rotation-allowed joint is joined. Process.
(9) Then, a step of releasing the tension of the tension material and removing the tension material.

In place of steps (4) and (5), between the column base on the rigid joint side or the vicinity of the column base and the intermediate portion of the beam, and between the column head on the rotation-allowable joint side and the beam. Tension materials are installed between the joint with the beam end or in the vicinity of the joint and the middle of the beam so as to intersect each other and not to interfere with the outdoor storage, It may be a step of introducing tension to the material so that the partial frame is structurally self-supporting (see FIGS. 7 and 8).

In addition, between the rigid joint-side pillar head or a portion near the pillar head and an intermediate portion of the beam, and a joint portion between the rotation-allowable joint-side pillar head and the beam end portion or a portion near the joint portion, and Tension materials are installed between the middle part of the beam and each other so as not to interfere with the outdoor storage, and tension is introduced into the tension material to structurally construct the partial frame. It can also be a self-supporting step (see FIGS. 10 and 11).

Further, in any of the above construction methods, when the partial frame members are connected to each other, (a) immediately before sliding each partial frame member, (b) after each partial frame member completes the slide moving step to a predetermined position, Alternatively, there are two possibilities after the slide movement process of the entire roof frame (all the partial frames) is completed and before the tension of the tension member is released.

The former (a) is disadvantageous in that a large-capacity slide device is required because the weight of the slide becomes heavier as the number of connected partial frames increases because it is before the slide movement.

In the latter case (b), since the slide weight is only the partial frame weight for one slide, the capacity of the slide device may be small, but the moving distance for one slide is long, and therefore the construction time is disadvantageous.
An outdoor storage roof structure of the present invention comprises a plurality of partial frames assembled at an assembly place of the roof frame, and the outdoor storage on slide rails laid on both sides of the outdoor storage. It is a roof frame constructed by sliding it to a predetermined position and covering it on the outdoor storage, and the partial frame slides on the slide rails on both sides of the outdoor storage. A plurality of pillars, and a plurality of beams spanning the outdoor storage between the two pillars, and, of the pillars on both sides of the outdoor storage, one of the pillar head and the beam One end is rigidly joined, and the column head of the other column and the other end of the beam are rigidly joined by a rotation-allowable joint and an insertion member that fixes the rotation of the rotation-allowable joint.
Further, in particular, between the joints between the column heads and the beam ends on the rigid joint side and the rotation-allowable joint side of the partial frame, or between the column bases on the rigid joint side and the intermediate portion of the beam, and between the beams. For introducing tension between the beam end on the rotation-allowed joint side and the middle part of the beam, or between the beam end on the rigid-joint side and the rotation-allowed joint side of the beam or in the vicinity thereof and the middle part of the beam Since each tension member is installed, tension is introduced into the tension member to make the partial frame structurally independent while sliding the partial frame on the slide rail to the predetermined position of the outdoor storage. Thus, the sliding movement of the partial frame can be performed extremely safely without making the foundation supporting the slide rail particularly rigid.
Further, by increasing or decreasing the number of partial frames in the laying direction of the slide rails in accordance with the amount of outdoor stored items, it is possible to construct a roof frame of optimum scale very easily and economically.

Furthermore, by incorporating an energy absorbing member such as a buckling restraint brace in at least a part of the beam end on the rigid joint side of the partial frame (at or near the joint between the column head and the beam), multiple partial frames can be installed outdoors. It is possible to enhance safety not only after the storage structure is installed at a predetermined position and the roof frame is completed, but also against an earthquake that occurs during sliding movement of the partial frame.

Since the present invention is based on the above means, the following effects can be obtained.
When constructing a shed on the existing outdoor storage by the slide method,
(1) A tensioning material that prevents horizontal displacement of the column head of the partial frame (inclination of the column) to the outside without causing horizontal reaction force on the column base of the moving partial frame is stacked high. The sliding movement can be performed without interfering with the stored outdoor storage.
(2) Since the horizontal reaction force is not generated in the column base of the partial frame during the sliding movement of the partial frame, the safety is high.
(3) Therefore, reinforcement of the foundation against the horizontal reaction force at the time of sliding movement is not necessary over the entire movement section.
(4) Therefore, the foundation construction cost can be significantly reduced as compared with the case of the conventional slide construction method.
(5) By incorporating an energy absorbing member such as a buckling restraint brace at the beam end of the partial frame, the safety is improved not only after the completion of the roof but also against an earthquake that occurs during sliding movement.

As shown in FIGS. 1 to 3, the outdoor storehouse of the present invention slides above the outdoor store 1 between slide rails 2 and 2 laid on both sides of the outdoor store 1 with the outdoor store 1 interposed therebetween. It comprises a roof frame 3 which is constructed so as to straddle an arch shape in the direction perpendicular to the axis of the rails 2 and 2, and the roof frame 3 is a plurality of which are assembled at a constant length in the laying direction of the slide rails 2 and 2. Is constructed from the partial frames 3a, 3b,.
Parts Frames 3a, 3b, ... an outdoor reservoir 1 plurality of posts A ₁ disposed respectively across the, A ₂ and the pole A _1, A outdoor reservoir between ₂ on the slide rails 2 It is composed of a plurality of arch-shaped beams B, B installed above the slide rail 1 in the direction perpendicular to the axes of the slide rails 2 and 2, respectively.

Next, a first embodiment of the method for constructing the outdoor storehouse of the present invention will be described (see FIGS. 1 and 3 to 6).
(1) First, slide rails 2 and 2 are laid across the entire length of both sides of the outdoor storages 1 stacked in a conical shape or a bank (FIG. 1).
(2) Next, the slide rails 2 and 2 are further extended to the assembly position of the roof frame 3 and laid to the position required for assembling the partial frames 3a, 3b,... Of the roof frame 3 (FIG. 1). reference).
(3) Next, at a place where the roof frame 3 is assembled, the partial frames 3a, 3b,... Which slide on the slide rails 2, 2 in the laying direction of the slide rails 2, 2 are assembled (FIG. 3). reference). The optimum number of the partial frames 3a, 3b,... Is assembled according to the amount of the outdoor storage 1 to be loaded.
In assembly, first, a plurality of pillars A ₁ and column A ₂ placed at regular intervals each in the axial direction of the slide rails 2, 2 on the slide rails 2, 2, with the respective column A ₁ Beams B are respectively installed between the pillars A ₂ above the outdoor storage 1 in the direction perpendicular to the axis of the slide rail 2.
Then, the beam end B _D stigmas portion D and the beam B pillars A ₁ rigidly joined (hereinafter "rigid joint n _1"), the opposite side beam end of the column capital portion C and the beam B pillars A ₂ of The part B _C and the part B _C are joined to each other in a joining state that allows the rotation to some extent (hereinafter, “rotation allowing joining part n ₂ ”).
(4) Next, with respect to each of the assembled subframes 3a, 3b,..., the height of the outdoor storage 1 is such that the beam end portion B _D on the rigid joint n ₁ side and the rotation-permissible joint n ₂ side. When the position is lower than the position of the straight line L connecting with the beam end B _C of the beam B, the tension material T ₁ is horizontally extended between both ends B _C and B _{D of} the beam B, and both beam ends B _{C of the} beam B are And B _D are connected by a tension material T ₁ (see FIG. 4).
(5) Next, the tension t is introduced into the tension material T ₁ so that the partial frames 3a, 3b,... Are structurally stabilized and self-standing (see FIG. 4).
(6) Next, each of the self-supporting partial frames 3a, 3b,... Is slid on the slide rails 2, 2 in order to slide to the predetermined position of the outdoor store 1 (see FIG. 4).
(7) Steps (3) to (6) are repeated until the entire outdoor storage 1 or its necessary range is covered.
(8) Next, after all the sliding movement steps of the partial frames 3a, 3b,... Are completed, the column head C and the end B of the beam B on the rotation-allowable joint n ₂ side of each partial frame 3a, 3b,. _An insertion member m is added to the joint with _C to rigidly join the joint between the column head C of the column A ₂ and the beam end B C of the beam B (see FIG. 5). Further, the partial frames 3a, 3b,... Are joined together.
(9) After that, the tension t of the tension material T ₁ is released, the tension material T ₁ is removed, and the assembling of the roof frame 3 is completed (see FIG. 6 ).

Since the first embodiment is as described above, it has the following features. In the conventional slide construction method shown in FIG. 2, a horizontal reaction force _RH (indicated by a horizontal arrow) is generated on the column bases F, F of the columns A ₁ , A ₂ of the partial frames 3a, 3b,. As shown in FIG. 3, if the joint between the column head portion C of the column A ₂ and the beam end portion B _C of the beam portion B is a rotation-permissible joint that allows rotation to some extent, the column bases F, F are normally used. Since it is also rotatable to a certain extent, the horizontal displacement δ is generated on the outside of the column head C of the column A _{2 due to} the weight of the partial frames 3a, 3b,..., And the horizontal reaction force R _H is not generated on the column bases F and F. That is, both the stigma and the pedestal form the columns of the rotation-allowed joints to form the horizontal roller mechanism. At this time, the horizontal rigidity in the straddling direction of the partial frames 3a, 3b,... depends on the pillar A ₁ on the rigid joint rigid part n ₁ side, and as shown by the chain double-dashed line in FIG. column a ₂ junction n ₂ side is inclined outwardly, but the beam B is deflected, since it is large Harima Frame, since these deformation amount is large, can not build Frames as designed.

Therefore, in the first embodiment, as shown in FIG. 4, with respect to the assembled partial frames 3a, 3b,..., The beam end B _C on the rotation-allowable joint side and the beam end B _D on the rigid joint side are provided. When the height of the outdoor store 1 is lower than the position of the straight line L that connects with, the tension material T ₁ that connects both beam ends B _C and B _D of the beam B is attached, and the rotation-allowable joint n as horizontal displacement δ of ₂ side stigma portion C of the column a ₂ of becomes substantially zero, it is a method for introducing a tensile force t to the tension member T _1. Therefore, since the amount of deformation can be controlled without generating the horizontal reaction force R _H on the column bases F, F, it is possible to construct the frame as designed.

Further, in this embodiment, since the maximum distance S ₀ between the tension material T ₁ and the beam B is secured to be large, the tension t may be relatively small, and the tension material T ₁ may be one set, which is cost effective. Is also advantageous.

The tension member T ₁ may be attached at a position higher than both beam ends B _C and B _D of the beam B. In that case, however, the maximum distance S ₀ is shortened, so that the effect of the tension member T ₁ is increased. Therefore, it is necessary to introduce a larger tension t.

Further, as shown by the dotted line in FIG. 4, in the case of the outdoor storage 1a stacked higher than the position of the tension material T ₁ , the outdoor storage ₁ interferes with the tension material T ₁ and cannot be applied.

Next, a second embodiment of the present invention, which is suitable when the height of the outdoor storage 1 is higher than the position of the straight line L connecting both beam ends B _C and B _D of the beam B, will be described (FIG. 1). , FIG. 3 and FIGS. 7-9).
Since the steps 1 to 3 are almost the same as the steps described in the first embodiment, the description thereof will be omitted and the step 4 will be described.
(4) For each of the partial frames 3a, 3b,... Assembled in steps 1 to 3, a tension material T that connects the column base portion F of the column A ₁ on the rigid joint n ₁ side and the intermediate portion of the beam B. ₁ and the tension member T ₂ that connects the beam end portion B _C of the beam B on the side of the rotation-allowable joint n ₂ and the intermediate portion of the beam B to each other so that they cross each other as much as possible and are stored outdoors. Install it so that it does not interfere with the object 1 (see FIG. 7).
(5) Next, the tension t is introduced into the tension members T _{1 and} T ₂ so that the respective partial frames 3a, 3b,... Are structurally stabilized and self-standing (see FIG. 7).
(6) Next, the self-supporting partial frames 3a, 3b,... Are slid on the slide rails 2, 2 to sequentially slide to a predetermined position of the outdoor store 1 (see FIG. 7).
(7) Steps (3) to (6) are repeated until the entire outdoor storage 1 or its necessary range is covered.
(8) The partial Frames 3a, 3b, after completing ... sliding step all, the junction between the beam end B _C stigma portion C and the beam B pillars A ₂ of rotation allowed junction n ₂ side An insertion member m is added to the portion to make the joint between the column head portion C of the column A ₂ and the beam end portion B _C rigidly joined (see FIG. 8). Further, the partial frames 3a, 3b,... Are joined together.
(9) Thereafter, by releasing tension t of the tension member T _1, T _2, completing the construction of the shed Frames 3 removing the tension member T _1, T ₂ (see FIG. 9).

Since the second embodiment is as described above, it has the following features. As shown in FIG. 7, the maximum distance S ₁ between the tension member T ₁ connecting the intermediate portion of the column base F and the beam B and the beam B is considerably larger than S _{0 of} the first embodiment (see FIG. 4). Since the length is shortened, it is necessary to increase the amount of tension t introduced, and at least two sets of tension materials T ₁ and T ₂ are required for each construction surface, even when the height of the outdoor store 1 is high. Since the amount of deformation can be controlled without generating the horizontal reaction force R _H on the column bases F, F, it is possible to construct the frame as designed.

Next, a third embodiment of the present invention, which is suitable for the case where the height of the outdoor storage 1 is high and the space between the outdoor storage 1 and the pillars A ₁ and A ₂ on both sides is small, will be described (FIG. 1, FIG. 3 and FIGS. 10 to 12). Since the steps 1 to 3 are almost the same as the steps described in the first embodiment, the description thereof will be omitted and the step 4 will be described.
(4) The tension members T ₁ and T ₂ that connect the beam end portions B _C and B _D of the beam B of the partial frames 3a, 3b,... They are mounted so that they intersect each other as much as possible and at a height that does not interfere with the outdoor store 1 (see FIG. 10).
(5) Next, a step of introducing tension t into the tension members T ₁ and T _{2 so} as to structurally stabilize the partial frames 3a, 3b,..., and make them self-standing (see FIG. 10).
(6) Next, the self-supporting partial frames 3a, 3b,... Are slid on the slide rails 2, 2 to slide to the predetermined position of the outdoor store 1 (see FIG. 10).
(7) Steps (3) to (6) are repeated until the entire outdoor storage 1 or its necessary range is covered.
(8) partial Frames 3a, 3b, after completing ... sliding step all, inserted at the junction between the beam end B _C stigma portion C and the beam B pillars A ₂ of rotation allowed junction n ₂ side A member m is added to form a rigid joint between the column head portion C of the column A ₂ and the beam end portion B _C (see FIG. 11). Further, the partial frames 3a, 3b,... Are joined together.
(9) After that, by releasing tension t of the tension member T _1, T _2, completing the construction of the shed Frames 3 removing the tension member T _1, T ₂ (see FIG. 12).

Since the third embodiment is as described above, it has the following features. In the third embodiment, as shown in FIG. 10, the maximum distance S between the beam B and the tension material T ₁ (T ₂ ) that connects the beam ends B _C and B _D of the beam B and the intermediate portion of the beam B. _{Since 2} is shorter than S _{1 of} the second embodiment (see FIG. 7), it is necessary to increase the amount of tension t to be introduced, and the tension materials T ₁ and T ₂ are at least 2 per surface. Although it is necessary to set, even if the height of the outdoor store 1 is high and the space between the outdoor store 1 and the columns A ₁ and A ₂ on both sides is narrow, it is horizontal to the column bases F, F. Since the amount of deformation can be controlled without generating the reaction force R _H , it is possible to construct the frame as designed.

In each of the above embodiments, the position to add the insert member m is an indoor side of the joint portion between the end portion B _C stigma portion C and the beam B pillars A ₂ (outdoor side rotation allowing bonding. Figure 5 other However, it may be on the outdoor side (rotation-allowed joint on the indoor side, not shown).

Further, the roof frame of the outdoor storage according to the present invention is used in any of the slide construction methods of the above-mentioned embodiments, and in the partial frames 3a, 3b,... At least the rigid joint n ₁ side as described below. By installing an energy absorbing member (not shown) such as a buckling restraint brace in the beam end portion _BD of the plurality of partial frames 3a, 3b,... Safety is improved not only after 3 is completed but also against an earthquake that occurs during sliding movement of the partial frames 3a, 3b,....
An energy absorbing member such as a buckling restraint brace may be provided on some of the beam ends B _D on the side of the rigid joint n ₁ or all of the beam ends B _D , if necessary. The beam ends B _C and B _D may be provided on both the joint n ₁ side and the rotation-allowable joint n ₂ side.

Shed Frame 3 parts Frames 3a, 3b, ... is until the sliding movement is completed, the joint between the beam end B _C stigma portion C and the beam B pillars A ₂ is inserted member m It is clear that the seismic resistance is considerably inferior to the seismic force in the straddle direction after the insertion member m is added. Also, when an earthquake in the span direction occurs during sliding movement, the bending moment acting on the joint between the column head D and the beam end B _D on the rigid joint n ₁ side is greater than that of the completed frame. Therefore, high axial forces of compression and tension are repeatedly applied to the member located at the beam end portion B _D.

From the above, if the member at such a position (beam end portion B _D ) is a member (not shown) having a high energy absorption capacity such as a buckling restraint brace, the sliding of the partial frames 3a, 3b,... Even if a large earthquake occurs during movement, it is possible to prevent the buckling restraint brace or the like from absorbing energy and damaging other parts of the partial frames 3a, 3b,....

Furthermore, if the insertion member m (see FIG. 5 and the like) on the beam end B _C side is also an energy absorbing member such as a buckling restraint brace, the completed roof 3 will have both beams B at the time of a large earthquake. Since the energy is absorbed at the beam ends B _C and B _D at two places, it is possible to construct the roof 3 having higher seismic performance.

The present invention is applied to the case where a slide construction method is adopted as a construction method for constructing a storage shed with existing existing outdoor storage stored outdoors (fuel wood chips, coal, etc.) in place. Since the horizontal reaction force of the column base can be suppressed during the sliding movement of the shed, the safety during construction can be improved compared to the conventional slide construction method, and the construction cost can be greatly reduced by simplifying the foundation structure. To do.

(3) At the assembly place of the roof frame, a plurality of pillars that slide on the slide rails on both sides of the outdoor storage, and bridge between the two pillars across the outdoor storage. A plurality of beams, and a joint between a column head of one of the columns and one beam end of the beam is rigidly joined, a column head of the other column and the other beam of the beam A process of assembling a plurality of partial frames in which the joint portion with the end portion is joined to allow rotation.
(4) Between the column base on the rigid joint side of the partial frame or between the column base and the intermediate portion of the beam, and the joint between the column head on the rotation-allowable joint side and the beam end or the same. A step of installing tension members between the vicinity of the joint portion and the middle portion of the beam so as to intersect each other and not to interfere with the outdoor storage.
(5) A step of introducing tension into the tension material to structurally make the partial frame self-supporting.
(6) A step of slidingly moving the self-supporting partial frame on the slide rail to a predetermined position of the outdoor storage.
(7) A step of repeating steps (3) to (6) until the entire outdoor storage or the necessary range thereof is covered.
(8) A step of attaching an insertion member to the joint between the column head and the beam end on the rotation-allowable joint side and rigidly joining the joint after the slide moving steps of the partial frame are all completed.
(9) Then, a step of releasing the tension of the tension material and removing the tension material. Slide rails laid on both sides of the outdoor storage, and assembled at the assembly location of the roof frame of the outdoor storage, and slide on the slide rail to slide on the outdoor storage. A construction method for an outdoor storage shed comprising a plurality of partial frames to be installed, the construction method for an outdoor storage shed including the following steps.
(1) A step of laying slide rails across the entire length of both sides of the outdoor stored article.
(2) A step of further extending and laying the slide rail to an assembly site of the roof frame.
(3) At the assembly place of the roof frame, a plurality of pillars slidably moving on the slide rails on both sides of the outdoor storage, and spanned between the two pillars across the outdoor storage. A plurality of beams, and a joint between a column head of one of the columns and one beam end of the beam is rigidly joined, a column head of the other column and the other beam of the beam A process of assembling a plurality of partial frames in which the joint portion with the end portion is joined to allow rotation.
(4) Tension materials may be crossed with each other at the joint between the pillar heads of the columns on both sides of the partial frame and the beam end, or between the joint and the middle of the beam. And a step of installing the outdoor storage so as not to interfere with the outdoor storage.
(5) A step of introducing tension into the tension material to structurally make the partial frame self-supporting.
(6) A step of slidingly moving the self-supporting partial frame on the slide rail to a predetermined position of the outdoor storage.
(7) A step of repeating steps (3) to (6) until the entire outdoor storage or the necessary range is covered.
(8) A step of adding an insertion member to the joint between the column head and the beam end on the rotation-permissible joint side to complete the joint after the sliding movement process of the partial frame is completed.
(9) Then, a step of releasing the tension of the tension material and removing the tension material.
