Description

  The present invention relates to a block height adjusting tool, and also relates to a block stacking method using the same. More specifically, when building an elevator shaft or the like for easily installing an elevator in an existing 4-story or 5-story mid-rise apartment building where no elevator is installed, the required gap between the upper and lower blocks The height of the upper block is adjusted with respect to the lower block to maintain the height-adjusted state, and finally the block height adjuster that can be easily removed from the upper and lower blocks Further, the present invention relates to a block stacking method using the block height adjusting tool.

  An elevator shaft is constructed for the purpose of easily installing an elevator in an existing four-story or five-story middle-rise apartment building where no elevator is installed. A construction method disclosed in Japanese Patent No. 185884 has been proposed.

  In this construction method, an elevator shaft is constructed by stacking a plurality of blocks having a substantially U-shaped planar shape on a foundation, and each block is integrated by applying an adhesive to the joint surface of the stacked blocks. , Insert a high-tension shaft core (a shaft core of a PC steel rod, etc.) with the bottom end embedded in the foundation into a vertical communication hole that is continuous vertically, and at least the top end of the high-tension shaft core By pulling at the uppermost part and pressing the uppermost block downward, the stacked blocks are fastened together and mortar is filled in the insertion hole through which the high-strength shaft core is inserted.

  As described above, since the elevator shaft is formed by integrating the blocks by applying an adhesive to the joint surfaces of the blocks to be stacked as described above, each part of the elevator shaft can be accurately adjusted unless a block with high dimensional accuracy is used. It is thought that it cannot be built well. This is because the accuracy of the elevator shaft constructed by stacking depends on the manufacturing error of the block. The manufacturing method of each block is not specified in the publication, but in order to manufacture each block with high accuracy, it is usually considered that the manufacturing method of match cast must be used. However, the matchcast manufacturing method is a method of manufacturing blocks on a long surface plate that extends in one direction, using manufactured blocks as a substitute for molds. In addition to the problem that the manufacturing cost is increased, there is a problem that the working space cannot be effectively used.

  In order to solve such problems, a joint structure of a shaft unit (block) in an elevator shaft disclosed in Japanese Patent Application Laid-Open No. 2004-352457 has been proposed. In this joining structure, when joining the shaft units to each other or on the foundation unit, first, level adjustment is performed by installing a plurality of iron plate liners for level and height adjustment around the main bar protruding from the lower side column part. In addition, a configuration is adopted in which a silicone sponge rubber for preventing leakage of mortar is installed around and the upper unit is hung and the protruding end of the lower main bar is positioned in the sleeve. By adopting such a configuration, there is an advantage that the required level and height can be adjusted by the iron plate liner even when a manufacturing error occurs in the block.

  However, when adjusting the level and height with such a steel plate liner, there is a problem that it cannot be adjusted with high accuracy because it is restricted by the thickness of the steel plate to be used. There was a case where the liner became an obstacle and the injected mortar did not spread evenly to each part. In addition, due to block manufacturing errors, the bottom surface of the stacked shaft units does not always come into contact with the top surfaces of all iron plate liners correctly, and floating parts are likely to occur. In some cases, the mortar was not properly filled between the lower surface of the shaft unit. As a result, the supporting force by the filled mortar becomes incomplete, and the strength of the elevator shaft may become unstable, for example, when an earthquake occurs.

  In order to solve such a problem, as shown in FIG. 4 of the drawing disclosed by the publication, a bolt having nuts screwed to the upper and lower ends and a shaft unit (block) to be joined Means have been proposed for adjusting the height with high precision by screwing the nuts through an adjusting connector comprising L-shaped brackets fixed to the upper and lower ends, respectively. When using the means for connecting the upper and lower shaft units (blocks) using such an adjusting connector, the level and height can be adjusted accurately, and the gap formed between the upper and lower shaft units can be Since there is no such iron plate liner, there is an advantage that mortar can be uniformly filled in each part of the gap.

  However, when using the adjustment connector, the bracket, bolts and nuts are exposed on the outer surface of the shaft unit (block), which not only makes the elevator shaft look bad, but also reduces the effective area of the elevator hoistway. There was a problem that.

  Japanese Patent Laid-Open No. 9-125418 has been proposed as one of means for connecting blocks with such bolts and nuts stored inside the blocks. However, the block connecting means using bolts, nuts and the like that pass through the insertion holes provided in the blocks have not been planned to be reused after the blocks are connected to each other. If the gap formed between the connected blocks is filled with mortar, etc., and then removed and reused, the bolts can be inserted through the insertion holes provided in the bracket or block unless the nut is removed. Since it cannot be removed, a lot of work is required for reusing bolts, nuts, brackets, etc., which causes a problem of poor work efficiency, which is not practical.

JP 2000-185884 A (page 4-5, FIGS. 1 and 2) JP 2004-352457 A (page 3, FIG. 3, FIG. 4) JP-A-9-125418 (page 4, FIG. 2)

The member is removed from the upper and lower blocks.

The present invention has the following excellent effects.
(1) According to the present invention, for example, even if manufacturing errors have occurred in the individual blocks to be stacked such as blocks constituting an elevator shaft and the dimensional accuracy is not good, such manufacturing errors are absorbed. Thus, the blocks can be stacked accurately. As a result, various block stacked structures such as an elevator shaft in which the verticality of each block and the height of each block are set with high accuracy can be constructed. In addition, since the manufacturing error can be absorbed in this way, a block manufactured by a method of manufacturing a match cast having a problem that the dimensional accuracy is high but the productivity is very bad and the manufacturing cost is increased is used. Therefore, it is possible to perform block stacking construction using a general block, and high construction economics can be achieved.
However, in the present invention, the adjustment bolt formed by screwing the nut member into the upper male screw portion and the lower male screw portion is configured to be easily attached to and detached from the upper and lower fixing members. Is fixed to the upper and lower blocks so that the upper and lower horizontal pieces are in the protruding state, and the adjusting bolt can be connected to the upper and lower horizontal portions provided with the notched portions without hindering the screwed nut member. Can be easily attached to a piece. Thereby, the height adjustment of an upper block can be performed efficiently. Further, when removing the height adjuster, the adjustment bolt can be easily removed from the upper and lower horizontal pieces only by loosening the screwed nut member as appropriate, without causing the nut member to become an obstacle. Since the upper and lower fixing members are independent of the adjusting bolt, the upper and lower fixing members can be safely and easily attached and detached without this becoming an obstacle. If an insertion hole is employed instead of the notch, it will be difficult to attach and detach the adjustment bolt.
As described above, according to the present invention, the height of the upper block can be adjusted with high accuracy and efficiency, and it is easy to remove the height adjuster from the block after the height adjustment. There is also an advantage that the removed height adjusting tool can be reused at another construction site.

(2) In addition, when the block stacking method according to the present invention is used, the height of the block is adjusted using a liner plate in order to install the upper block on the lower block with an elastic water blocking material interposed therebetween. Unlike the height adjusting means, it is possible to finely adjust the height of the block. In addition, since the stacked liner plates do not have the possibility of non-uniform filling of the filler such as grout, the block product which is stable in strength can be obtained by curing the liquid filler uniformly filled in the filling space. A heavy structure can be constructed.

(3) When a guide piece is provided on any one of the upper and lower fixing members, when the upper block is installed by the guide action of the guide piece, the horizontal direction of the upper block relative to the lower block Can be easily positioned.

(4) When the restriction engagement portion is provided on the upper and lower horizontal pieces, the adjustment bolt moves toward the open end of the notch portion by engaging the nut member in contact with the restriction engagement portion. Therefore, the height adjustment state of the block can be held more safely.

(5) When the present invention is applied to stacking construction of blocks constituting an elevator shaft, when the upper and lower fixing members are fixed to the inner surfaces of the upper and lower blocks, the blocks are stacked. Scaffolds can be installed in the internal space of the block. Therefore, the assembly work of the scaffold can be simplified, and the movement distance of the operator can be reduced when the height adjustment work of the block is performed, so that the construction efficiency can be improved. Also, since the scaffolding is installed in the internal space of the block, unlike the case where the scaffolding is provided so as to surround the block, it is easy to visually check the mounting state of all the height adjustment tools, Safe construction is possible. In this way, when the upper and lower fixing members are fixed to the inner surfaces of the upper and lower blocks, when guide pieces are provided on the upper block or the lower block, when the block is suspended, Unlike the case where the upper and lower fixing members are fixed to the outer surfaces of the upper and lower blocks, the outer surface side of the block is not damaged by the guide pieces even when the edge portion is rubbed and damaged by the guide pieces. Therefore, there is no possibility that the guide piece impairs the appearance of the elevator shaft.

The inserts 77 and 77 embedded in the second block 2B are arranged in the same manner as the inserts 77 and 77 embedded in the first block 1B as shown in FIG. Immediately above, it is embedded in the inner surface 60. As a result, the upper horizontal piece 106 protrudes horizontally from the inner surface 60 of the second block 2B. As shown in FIG. 1, the upper and lower horizontal pieces 106 and 73 are connected to the first block 1B (lower block Bb) by passing the second block 2B (upper block Ba) through the elastic water stop material 124. ) When it is installed on the top, it is in a vertically opposed state, and the upper and lower cutouts 109 and 81 are in a vertically opposed state.

  The upper fixing member 62 is fixed to the second block 2B by placing the upper vertical fixing piece 105 on the second block 2B prior to placing the second block 2B on the elastic waterstop 124. The fixing may be performed on the inner surface 60, or alternatively, the upper vertical fixing piece 105 may be fixed on the inner surface 60 after the second block 2B is placed on the elastic water stop material 124. . In the present embodiment, after the second block 2B is placed on the elastic water blocking material 124, the upper fixing member 62 is fixed to the inner surface 60 of the second block 2B.

  FIGS. 19 to 20 illustrate the guide action of the guide piece 76 when the second block 2B is suspended above the installed first block 1B, and the upper end of the first block 1B is illustrated. The second block 2B is placed so that the block lower end portion 135 is accommodated in a space (FIGS. 16 and 18 to 20) formed outside the guide pieces 76, 76, 76, and 76 that protrude upward at the four corners. Hanging down. In this suspension, as shown in FIGS. 19 to 20, the opposite side walls of the second block 2 </ b> B are formed on the inclined guide surfaces 92 and 92 of the guide pieces 76 a and 76 a provided on the left and right side wall portions 27 and 27. The inner edge portions 93 and 93 of the portions 136 and 136 are appropriately guided and guided by the vertical guide surfaces 91 and 91, and the second block 2B is lowered. As a result, the position of the second block 2B in the horizontal plane is set as required.

  In order to guide the inner edge portion 93 of the upper block 2B by the guide pieces 76b and 76b protruding at the upper end of the rear wall portion 30, as shown by an arrow in FIG. 19, the second block 2B, the front side wall 94 is pressed forward from the inner side while the inner side edge 93 of the rear side wall 30 is abutted against the vertical guide surfaces 91, 91 of the left and right guide pieces 76, 76. The second block 2B is suspended while contacting.

  By going through such work steps, the verticality of the second block 2B and the height of the second block 2B relative to the first block 1B are roughly set. In this state, the upper and lower horizontal pieces 106 and 73 face each other, and the upper and lower cutouts 109 and 81 face each other.

  In this state, as shown in FIGS. 1 and 21, the upper and lower nut members 66 and 67 are screwed at a predetermined interval above and below the upper male screw portion 65 and are required above and below the lower male screw portion 69. The adjusting bolt 63 formed by screwing the upper and lower nut members 70 and 71 at intervals is fitted in the upper and lower cutout portions 109 and 81 in the lateral direction. More specifically, this insertion process is performed between the upper and lower nut members 66 and 67 screwed into the upper male threaded portion 65 (in this embodiment, between the upper and lower second washers 125 and 125). ) 65a and the upper and lower nut members 70 and 71 screwed into the lower male screw portion 69 (in the present embodiment, between the upper and lower second washers 125 and 125) 69a, The upper male threaded portion 65a existing between the upper and lower second washers 125, 125 is aligned with the open end 122 (FIG. 1) of the upper notched portion 109 so that the notched portions 109, 81 can be interposed. At the same time, the lower male screw portion 69a existing between the upper and lower second washers 125, 125 is aligned with the open end 118 (FIG. 1) of the lower cutout portion 81. In this state, as shown in FIG. 21, the adjusting bolt 63 is fitted in the upper and lower cutout portions 109 and 81 in the lateral direction. At this time, as shown in FIG. 3, the outer end portions 111 and 84 of the second washer 125 are in contact with the restricting engagement portions 112 and 86 on both sides.

  After that, as shown in FIG. 22, the upper and lower nut members 70 and 71 screwed into the lower male screw portion 69 are tightened so that the lower horizontal piece 73 is held. Accordingly, the adjustment bolt 63 is in a vertically standing state with the bolt lower end portion 139 fixed to the lower horizontal piece 73.

  Thereafter, the upper and lower nut members 66 and 67 screwed to the upper male threaded portion 65 are screwed, so that a required gap is provided between the upper and lower blocks Ba and Bb via the upper fixing member 62. G (FIG. 2) can be provided to adjust the height of the upper block Ba. In the present embodiment, since the height adjusters 1, 1, 1, 1 are disposed at the four corners of the block, the upper and lower nut members 66 of the upper male screw portion 65 of each height adjuster 1 are provided. 67, by screwing the upper nut member 66 downward, or by screwing the lower nut member 67 upward, the verticality of the second block B2 is increased. It is possible to secure the second block B2 with respect to the first block B1.

  This height adjustment will be described in more detail. As shown in FIG. 23-1, the upper nut member 66 is screwed downward while the lower nut member 67 is loosened. The elastic water blocking material 124 on which the eye block B2 is placed and is in an elastically compressed state can be further elastically compressed. On the contrary, as shown in FIG. 23-2, the second block B2 can be lifted by screwing the lower nut member 67 upward while the upper nut member 66 is loosened. The elastic water blocking material 124 can be elastically restored by an amount corresponding thereto. By the screwing operation of the upper and lower nut members 66 and 67, the verticality and height of the second block B2 can be finely adjusted.

  The height adjustment at the four locations of the block is not always performed in the same way due to block manufacturing errors and weight deviations, etc., and the required height adjustment is performed on some or all of the height adjustment tools. As a whole, the verticality and height of the placed second block B2 are finely adjusted. For example, when the 20 mm elastic waterproofing material 124 is compressed to 15 mm by the installation of the second block B2, the elastic waterproofing material 124 is partially compressed to 8 mm. When this occurs, it may be lifted by 2 mm.

  And the required water-stopping effect (water-stopping effect that can prevent grout leakage) is obtained by compressing the upper and lower wall thicknesses 20 mm of the elastic water-stopping material 124 in a free state within a range of 5 to 13 mm. It is done. With the height adjusted in this manner, the filling of the liquid filler, which is surrounded by the elastic waterproofing material 124 in the joint portion 140 (FIG. 2) between the first block B1 and the second block B2. A space 59 is formed.

  In this adjusted state, as shown in FIG. 2, the upper and lower nut members 66 and 67 of the upper male threaded portion 65 are tightened to bring the upper horizontal piece 106 into the clamping state. In this state, as shown in FIG. 3, the tip portions 111 and 84 of the upper and lower second washers 125 and 125 protrude from the upper surfaces 110 and 74 of the upper and lower horizontal pieces 106 and 73, respectively. Since the engaging portions 112, 112, 86, and 86 are engaged in contact with each other, the adjustment bolt 63 is in the height adjustment state in which the upper and lower nut members 66 and 67 are tightened. The movement toward the open ends 122 and 118 of 109 and 81 is prevented, so that the height adjustment state is reliably maintained.

  After the second-stage block B2 is thus installed, the scaffold is extended upward in accordance with the upper end height of the second-stage block B2.

  Thereafter, as shown in FIG. 10, the third-stage block B3 including the third block 3B is installed on the second-stage block B2, and the installation procedure is the same as described above. More specifically, as shown in FIG. 11, another PC is connected to each upper end portion 56 of the PC steel bar protruding from the upper end surface 51 of the second-stage block B2 via the coupler 10. The steel bar 11 is connected so as to protrude upward. At the same time, elastic waterproofing materials 124, 124 having the same configuration as described above are stuck on the lower surface 126 in the circumferential direction at the inner and outer edge portions of the upper end surface 51. As a result, as shown in FIG. 25 (A), a space portion 108 with the PC steel rod 11 interposed therebetween is formed by the inner and outer elastic water stop materials 124, 124.

  Then, as shown in FIGS. 10 and 24, the lower fixing member 61 is connected to the front end of the inner surface 60 of the left and right side walls 142, 142 of the upper end portion 60a of the inner surface 60 of the second block B2. At both ends of the inner wall 60 of the rear wall 143 and the rear wall 143, bolts are fixed at sites that are retracted from the edge 130 of the hunches 129, 129, 129, and 129. The bolt is fixed by fixing the lower vertical fixing piece 72 with fixing bolts 79 and 79 as shown in FIG. As a result, as shown in FIG. 25A, the lower horizontal piece 73 protrudes horizontally from the inner surface 60, and the guide piece 76 protrudes upward from the upper end surface 51 of the second block B2. It becomes a state.

  Thereafter, the third block 3B (third block B3) is suspended on the elastic water stop material 124 in a state where each of the PC steel rods 11 is inserted into the corresponding insertion hole 33. During the suspension, the guide pieces 76, 76, 76, 76 of the lower fixing member 61 guide the inner edge 93 of the third-stage block B3. At the time of suspension, the inner edge portion 93 of the third block B3 is in contact with the vertical guide surfaces 91 and 91 of the guide pieces 76 and 76 protruding from the rear side wall portion 143. The side wall portion 149 (FIG. 6, FIG. 25 (B)) in front of the third block 3B is pressed outward from the inside as indicated by an arrow in FIG. 25 (B). As a result, the position of the third-stage block B3 in the horizontal plane is set as required.

The fixing member 62 is bolted to the inner surface 60 of the third block B3. Thereafter, in the same manner as shown in FIG. 21, the upper male screw portion 65 and the lower male screw portion 69 of the adjusting bolt 63 are fitted into the upper and lower cutout portions 109 and 81 in the lateral direction, and the lower male screw portion is inserted. The upper and lower nut members 70, 71 screwed to the portion 69 are tightened so that the lower horizontal piece 73 is held. Thereafter, in the same manner as described above, the upper and lower nut members 66 and 67 screwed to the upper male screw portion 65 are screwed as required, whereby the third-stage block is interposed via the upper fixing member 62. While adjusting the height of B3, the elastic waterproofing material 124 is brought into a required compressed state in which the waterproofing can be ensured with the height adjusted. By adjusting the height of each of the height adjusters 1 in this way, the verticality of the third-stage block B3 can be secured, and the third-stage block B3 is required as compared with the second-stage block B2. The height can be adjusted.

  The fixing work and the height adjusting work of the upper and lower fixing members 61 and 62 can be performed in the internal space of the block using the scaffold. After the third-stage block B3 is adjusted in this way, the scaffold is extended upward in accordance with the upper end height of the third-stage block B3.

  With the third-stage block B3 placed on the elastic water stop material 124 in this way, as shown in FIG. 10, the upper end portion 150 of the connected PC steel rod 11 is The block B3 protrudes upward from the upper end surface 151.

  Thereafter, as shown in FIG. 12, the lower fixing member 61 is bolted to the inner surface 60 of the third-stage block B3 in the same manner as described above. Thereafter, the fourth block 4B (fourth-stage block B4) is suspended while being inserted into the corresponding insertion holes 33 of the PC steel rod 11, and the third-stage block 4B is suspended in the same manner as described above. It is hung on the elastic water stop material 124 provided around the inner and outer edge portions of the upper surface 151 of the block B3. During the suspension, the position of the fourth block B4 in the horizontal plane is set as required by the guide action of the guide piece 76.

  With the fourth-stage block B4 thus placed, as shown in FIG. 12, the upper end portion 153 of the PC steel rod 11 projects above the upper end surface 52 of the fourth-stage block B4. Therefore, a new PC steel rod 11 is connected to the upper end portion 153 through the coupler 10 as shown in FIG. Thereafter, as shown in FIG. 12, the upper fixing member 62 is fixed to the inner surface 60 of the rectangular tube portion of the fourth-stage block B4 in the same manner as described above. Thereafter, in the same manner as shown in FIG. 21, the upper male screw portion 65 and the lower male screw portion 69 of the adjustment bolt 63 are connected to the upper and lower cutout portions 109, 109 provided on the upper and lower horizontal pieces 106, 73. 81, the lower end portion 139 of the adjusting bolt 63 is fixed to the lower horizontal piece 73 in the same manner as shown in FIG. Thereafter, the upper and lower nut members 66 and 67 screwed to the upper male screw portion 65 are screwed in the same manner as shown in FIGS. 23 to 24 to adjust the height of the fourth block B4. The vertical adjustment of the fourth block B4 is ensured by the height adjustment operation of the four height adjustment tools 1, 1, 1, 1, and the fourth block B4 is moved to the third step.

Further, when the upper and lower fixing members 62, 61 are removed in this way, an opening of the insert is formed at the removed mark. In this embodiment, the upper and lower fixing members 61, 62 are connected to the inner surfaces 60 of the upper and lower blocks Ba, Bb. 27, unlike the case where it is fixed to the outer surfaces 167, 167 of the upper and lower blocks Ba, Bb as shown in FIG. 27, the insert remaining in the block after the upper and lower fixing members 61, 62 are removed. There is no risk of the appearance of the elevator shaft being damaged by the 77 holes.

  In the present embodiment, since the scaffold is installed in the internal space of the block as described above, the assembly work of the scaffold can be simplified, and work such as attaching the height adjuster 1 to the inner surface 60 of the block B is performed. The distance traveled by the person can be reduced and the work can be done efficiently. And since the worker who got on the scaffold can confirm the mounting | wearing state of all the height adjustment tools easily visually, construction can be performed reliably and safely.

  If the height adjuster 1 is fixed to the outer surface 167 of the block B as shown in FIG. 27, it is necessary to provide a scaffold so as to surround the block. In addition to causing a rise, the operator has to move the scaffold in the circumferential direction, so the moving distance on the work becomes large and the work efficiency is poor. In addition, there is a disadvantage that it is difficult to confirm whether or not the height adjusting tool is attached to a necessary portion. When the height adjuster 1 is provided on the outer surface of the block, the outer edge 166 (FIG. 27) of the suspended block is guided by the inclined guide surface 92 and the vertical guide surface 91 of the guide piece 76.
