A third vertical clearance CV3 is formed by the spacer 23 between the upper columnar sealing block 18 and the column 1 and upward from the third lateral clearance CT3.

  In particular, a third vertical clearance CV3 is formed in series along the height direction of the opening 4 between the side surface of the column 1 and the column-side sealing block 18 and the upper and lower corner sealing blocks 21 and 22. However, the third longitudinal clearance CV3 is sequentially formed according to the progress of the stacking in relation to the construction procedure of stacking the blocks.

  The third lateral clearance CT3, the third vertical clearance CV3, the lower position oblique clearance CS4, and the upper position oblique clearance CS5 are sealed with the seal material 11 to form a columnar filling passage P4.

  The various blocks and these blocks and the upper and lower beams 2 and 3 and the left and right columns 1 are joined by filling the clearance with an adhesive. Before the adhesive material is filled into the clearance, the clearance between the stacked blocks and the like is sealed by applying the sealing material 11 from the front surface side and the back surface side of the block, as shown in FIGS. Thus, filling passages P1 to P4 are formed.

  FIG. 16 shows a portion where the groove 12 is formed on the entire hypotenuse s, such as a joint portion between the general portion octagonal blocks 6. The groove 12 increases the adhesive surface and guides the adhesive along the inclined direction of the hypotenuse s to ensure the adhesive strength, and at the same time, smoothes the filling of the adhesive and also smoothes the air from the clearance. Prevents air bubbles from being discharged.

  Further, as shown in FIG. 17, in addition to the discharge of air from the clearance and the confirmation of the filling of the adhesive, it is possible to perform an operation of further filling the adhesive into various places in the filling passage after the confirmation of the filling. In addition, a closing member 19 with an air vent hole 19a is used. In the illustrated example, the closing member 19 is made of an L-shaped aluminum angle material.

  By appropriately disposing the closing member 19 in the upper opening portion of the clearance forming the filling passage, the air in the filling passage is discharged from the air vent hole 19a, and the adhesive is filled by overflowing from the air vent hole 19a. After confirming this, by closing the air vent hole 19a with the detachable plug member 20, the adhesive material can be filled to a position higher than the installation position of the closure member 19.

  In addition, since air gathers in a high place, it is desirable to provide the air vent hole 19a near the bottom of the fitting recess 15 (upper side of the closing member 19).

  11 and 12, the lower beam upper filling passage P <b> 1 formed by stacking the upper beam sealing block 9, the lower corner sealing block 21, and the general part octagonal block 6 on the lower beam 3 is used. Explain the construction on the lower beam.

  As shown in FIG. 11, the first lateral clearance CT1 between the upper beam sealing block 9 and the lower corner sealing block 21 and the lower beam 3 is inserted into one column 1 of the opening portion 4. A series of adhesives are filled from the injection pipe 24 toward the other pillar 1. At this time, the air vent pipe 25 is inserted into the upper open portion of the first vertical clearance CV1 to perform air venting.

  When the adhesive fills the first lateral clearance CT1 and the first longitudinal clearance CV1, the adhesive overflows from the air vent pipe 25, and the filling can be confirmed. The space between the pillar 1 and the lower corner sealing block 21 is also filled with adhesive, and this filling can be confirmed by overflow from the upper open portion of the lower corner sealing block 21.

  Next, as shown in FIG. 12, the general octagonal block 6 is stacked on the on-beam sealing block 9, and the injection pipe 24 is inserted into the upper open portion of the first longitudinal clearance CV <b> 1, and the first diagonal The adhesive is filled from below to above the directional clearance CS1.

  Regarding the periphery of the lower corner sealing block 21, the bottom pillar sealing block 18 is placed on the lower corner sealing block 21 and the general octagonal block 6, and the lower corner sealing block 21 An injection pipe 24 is inserted into the upper open portion, and the adhesive is filled from below to above with the injection pipe 24. At this time, before filling, a closing member 19 with an air vent hole is detachably attached to the upper open part of the oblique sides s, 18s between the general octagonal block 6 and the columnar sealing block 18.

  The adhesive rises the oblique sides s, 18s between the general octagonal block 6 and the columnar sealing block 18 and the third longitudinal clearance CV3 on the side of the column 1, and first, the upper open portion of the oblique sides s, 18s. Overflow from the air vent hole 19a of the closing member 19 of the above.

  If it overflows, the air vent hole 19 a is closed with the plug member 20. When the adhesive is filled again after closing, the adhesive further rises along the third longitudinal clearance CV3 and overflows from the upper open portion of the columnar sealing block 18, thereby sealing the lower corner. With the block 21 as a base point, it is possible to confirm the filling of the adhesive material around the lowermost general octagonal block 6 and the columnar sealing block 18.

  By filling the lower beam upper filling passage P1 with the adhesive from the lower side to the upper side, the lower beam 3, the upper beam sealing block 9, the lower corner angle sealing block 21, and the general part octagonal block 6 are joined together. Construction on the beam can be completed. Moreover, the filling of the adhesive material under the columnar filling passage P4 can also be finished.

  Next, with reference to FIG. 12, the general portion filling passage P2 formed by stacking the lowermost general octagonal block 6 to the upper octagonal block 7 constructed by the construction on the lower beam is used. Describe the construction of the part.

  As shown in FIG. 18, the injection pipe 24 is inserted into the lower open portion of the second diagonal clearance CS <b> 2, and the adhesive is filled from the lower side to the upper side with the injection pipe 24. Since the adhesive material is guided by the groove 12 and rises, and the air has escaped from the upper open portion of the second diagonal clearance CS2, it overflows from the upper open portion. it can.

  By filling the general part filling passage P2 with the adhesive from the bottom to the top, the general part construction for joining the octagonal blocks 6 and 7 can be completed.

  Next, with reference to FIG. 13, the pillar-side construction performed using the pillar-side filling passage P <b> 4 formed by stacking the pillar-side sealing blocks 18 between the general part octagonal block 6 and the pillar 1 will be described. .

Prior to the filling operation, the injection pipe 24 is positioned in the lower open part of the lower diagonal clearance CS4, the third vertical clearance CV3 is positioned slightly below the third horizontal clearance CT3, and the air vent pipe 25 is While being inserted, the closing member 19 with the air vent hole is detachably attached to the upper open portion of the upper position oblique direction clearance CS5. Next, the adhesive material is filled from the injection pipe 24.

  The adhesive material flows into the lower position oblique direction clearance CS4 from the lower side to the upper side, flows into the third lateral clearance CT3, and overflows from the air vent pipe 25. The overflow can be confirmed to fill the clearances CS4 and CT3.

  Next, the air vent pipe 25 is sealed, and an adhesive is filled from the injection pipe 24. This time, the adhesive material flows into both the upper position oblique direction clearance CS5 and the third longitudinal direction clearance CV3 from the lower side to the upper side. When the adhesive reaches the upper open portion of the upper position oblique direction clearance CS5, the adhesive overflows from the air vent hole 19a of the closing member 19, thereby confirming the filling of the upper position oblique direction clearance CS5.

  At this time, an upward convex fitting convex portion 14 is formed on the lower octagonal block 6, and a fitting concave portion 15 is formed on the lower oblique side 18 sb of the columnar sealing block 18 on the upper side. Further, a flat surface 30 is formed on the upper side in the inclination direction of the lower hypotenuse 18sb. As the adhesive is filled, light air is pushed up by the adhesive and collected from the front surface side and back surface side of the block toward the fitting recess 15, and the flat portion 30 has no groove 12, It flows smoothly through the upper position diagonal clearance CS5 and can be smoothly pushed and discharged along the fitting convex portion 14 toward the air vent hole 19a of the closing member 19, and the block is sealed from the front and back sides. Even if it seals with the material 11, it can be filled with an adhesive material densely, without a bubble pool being produced. Such an action can be ensured in the same manner even at a similar part in the construction stage shown in FIG.

  Next, the air vent hole 19 a is sealed with the plug member 20, and the adhesive material is further filled from the injection pipe 24. The adhesive rises from the lower side to the upper side in the third longitudinal clearance CV3 and overflows from the upper open part of the columnar sealing block 18. Thereby, filling of the adhesive material to the whole column side filling passage P4 can be confirmed.

  By filling the pillar filling passage P4 with the adhesive from the bottom to the top, the pillar construction for joining the pillar 1, the pillar sealing block 18 and the general part octagonal block 6 to each other can be completed.

  Next, using FIG. 14, the lower octagonal block 7 and the upper corner sealing block 22 are stacked under the upper beam 2 with respect to the upper octagonal block 7 constructed by the general construction.

The air vent member 16 is inserted in communication with the 13 places on the flat surface. As described above, the flat surface 13 is formed only on the upper side in the inclination direction of the oblique side 10s, and the grooves 12 face each other on the lower side in the inclination direction of the oblique side 10s.

  The air that rises in the third oblique clearance CS3 flows smoothly toward the front and back of the block because there is no groove 12 in the flat portion 13 due to the adhesive guided from below to above in the groove 12. It is supposed to be discharged.

Although it accumulates and is not easily discharged, as shown in FIG. 24 below the upper beam 2, since the fitting convex portion 14 is convex downward on the upper side, the pushed-up air is directed toward the front and back of the block. The air can be pushed out in the lateral direction, and air can be discharged from the air vent member 16 very smoothly.

  The adhesive material is filled from the injection pipe 24 inserted into the lower open portion of the third diagonal clearance CS3. The adhesive rises upward from below to the third diagonal clearance CS3, and the air is pushed out by the adhesive and is discharged from the two air vent members 16.

  When the adhesive reaches the air vent member 16 at the upper open portion of the third diagonal clearance CS3, it overflows from this, and it can be confirmed that the third diagonal clearance CS3 is filled.

  Next, when the air bleeding member 16 in which overflow has occurred is sealed and further filled with an adhesive, the adhesive is now removed from the air bleeding member 16 inserted at the intersection of the second longitudinal clearance CV2 and the second lateral clearance CT2. As a result, overflow of the adhesive material to the second longitudinal clearance CV2 can be confirmed.

  The adhesive filling the periphery of the upper corner sealing block 22 is performed in the same manner as the columnar filling passage P4. However, as shown in FIGS. 21 to 24, the air vent member 16 is connected to the third longitudinal clearance CV3. And the fitting protrusion 14 of the upper corner sealing block 22 is fitted into the fitting depression 15 of the upper octagonal block 7. Thus, air can be smoothly discharged from the front surface side and the back surface side of the block.

As shown in FIGS. 21 and 22, the upper beam 2 is formed with a plurality of cutout portions 17 that communicate with the second lateral clearance CT2 and vent air therefrom, as shown in FIGS. In the illustrated example, notches 17 are formed in the upper beam 2 from both sides in the width direction so as to roughly correspond to the position of the base portion 10a of the under-beam sealing block 10.

  The adhesive material is filled in a series from the injection pipe 24 inserted on one column 1 of the opening portion 4 toward the other column 1. When the adhesive fills the second lateral clearance CT2, it overflows from the notch 17 and can be confirmed to be filled. Since the adhesive material sequentially overflows from the plurality of notches 17, the notches 17 that have overflowed are sequentially sealed.

  The upper beam 2, the lower beam sealing block 10, the upper corner sealing block 22, and the upper octagonal block 7 are joined to each other by filling the upper beam lower filling passage P 3 with the adhesive from the lower side to the upper side.
