On the concrete for fixing, the present packer is cast between the upper surface of the concrete and the base of the air conditioner or the like to form an air conditioner or the like in an underground space. When adjusting the height and horizontality of the machine base, a surface height fine adjustment device with a helical rotation operation mechanism is arranged at a plurality of predetermined locations near the main packer placing site, and the helical rotation operation mechanism is provided. The gist of the present invention is to adjust and set the height and the level of the horizontality by using the attached surface height fine adjustment tool, and then form the main packer. According to the above-described structure, when adjusting the height and the level of the machine base, a spiral rotating mechanism with a helical rotating mechanism arranged at a plurality of predetermined locations near the packer placing site on the foundation concrete is provided. Adjust and set the height and level of the machine base with the surface height fine adjustment tool,
Thereafter, by forming the above-mentioned packer, adjustment of the installation level of the air-conditioning equipment and the like is extremely easily performed, the work efficiency and the installation accuracy are improved, and the labor and time required for the work are reduced as much as possible. In addition, the work period of the entire work can be shortened as much as possible. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention in an installation construction method for air conditioning equipment and the like in an underground space will be described below with reference to FIGS. In the present embodiment described below, in the case of an air conditioner installed in an underground space, a case will be described in which a blower constituting the air conditioner is installed. First, in the installation state of the blower 1,
As shown in FIG. 1 and FIG. 2, in the underground space S, a blower 1 is placed on a foundation concrete 2 cast in a predetermined shape corresponding to the form of the blower 1 to be installed.
A metal bottomed formwork 4 to 4 which constitutes a metal shaping apparatus for placing an anchor bolt 3 in a portion to be installed is concretely cast integrally with the foundation concrete 2, and a temporary packer is placed on the foundation concrete part 2. The base 6 of the blower 1 is placed with the metal molds 4 to 5 interposed therebetween.
The anchor 7 is fixed between the upper surface of the concrete 9 and the lower surface of the machine base 6.
Is formed, and the machine base 6 is fixed by fastening means such as nuts via the anchor bolts 3,
A blower 1 constituting an air conditioner or the like is installed on a foundation concrete 2 in an underground space. Hereinafter, the installation work method will be specifically described. First, the foundation concrete 2 is installed on the floor slab with the anchor bolts for the reinforcement of the blower foundation set in accordance with the portion where the blower 1 is to be installed. Form. A metal bottomed formwork (also referred to as an anchor sleeve) 4, which will be described later, is incorporated into the reinforcement arrangement frame 8 and connected and fixed to a circumferential reinforcing bar. Thereafter, a mold (wooden) of the entire blower foundation is formed, and the foundation concrete 2 is cast. (This is referred to as a basic formation step.) That is, a reinforcement arrangement frame 8 framed into a square shape or the like for the foundation concrete 2
At the same time, after arranging a metal bottomed formwork 4 for concrete 9 for fixing anchor bolts to be described later, a formwork (not shown) of the entire blower base is constructed and the base concrete 2 is formed.
Performing casting. An inner diameter portion of the bottomed metal frame 4 is formed as an anchor bolt setting hole, and an anchor bolt having a U-shaped lower end bent substantially at the center of the anchor bolt setting hole. 3 is erected. In this case, as shown in FIG. 5, the metal bottomed formwork 4 is formed in a metal bottomed cylindrical shape such as a zinc-iron plate, for example. The reinforcing frame 8 can be inserted into the metal bottomed formwork 4 as it is, and the metal bottomed formwork 4 can be arranged by the circumferential reinforcing bar in the reinforcing arrangement frame 8. It can be hooked and erected through a hook (not shown) on a reinforcing bar in the reinforcing arrangement frame 8 inserted into the metal bottomed formwork 4 to improve the workability of each binding operation. Things. Furthermore, the adhesiveness between the metal bottomed formwork 4 and the concrete for placing the foundation concrete 2 is improved, and the placement accuracy of the foundation concrete part 2 is enhanced. Next, after dismantling the formwork in the basic concrete 2, a smear is formed on the basic concrete 2, and a temporary packer 5 is placed on the basic concrete 2.
5 to 5 (three positions are shown in FIG. 3) corresponding to the blower 1 to be installed.
(Temporary packer forming step) [0013] As shown in Fig. 6, each temporary packer 5 is made of a steel mold 10 having a rectangular shape and a predetermined height, which is divided into two parts in the horizontal direction. ), And non-shrinkable mortar (pad type) is charged into the form 10 several times (preferably about 5 times) according to the scale and compacted while applying vibration by vibrator means. Is formed. In this case, the non-shrinkable mortar (pad type) is divided into several times (preferably about 5 times) according to the scale amount and charged, whereby the non-shrinkable mortar (pad type) is quickly solidified to the upper portion of the mold 10. Is what you can do. Then, a lock base (parallel liner) is placed on the temporary packer 5 made of the non-shrinkable mortar (pad type).
11 is buried in the temporary packer 5 while being vibrated by vibrator means to about 1/3 (see FIG. 6). In this case, the adjustment is performed while adjusting the parallelism of the upper surface of the lock base (parallel liner) 11, and fine adjustment is performed on a high portion with a rubber hammer or the like. Next, a pair of height adjusting members 12 (tapered liners) having sliding tapered surfaces opposed to each other are placed on the lock base (parallel liner) 11 on the temporary packer 5, and the height is adjusted. The machine base 6 of the blower 1 which is an air conditioner or the like to be installed via the adjustment member 12 (taper liner) is mounted on the machine base 6 and the height level and the horizontality of the machine base 6 are separately provided as described later. It is adjusted and set by the operation of the surface height fine adjustment device 13 having a spiral rotation operation mechanism (referred to as a machine base installation temporary core adjustment process). As shown in FIG. 9, the surface height fine adjustment device 13 having the helical rotation mechanism has a pair of sliding taper surfaces 14 and 15, such as a leveling block, which are in sliding contact with each other. And fixed means 16 and 17 on the fixed side and movable side, and a screw means 18 for connecting the movable side adjustable base 17 to the fixed side adjustable base 16 so that the upper surface thereof moves up and down in parallel. When the screw means 18 rotates forward and backward, the movable adjustment table 17 is moved up and down using the sliding tapered surface to adjust the height. In the screw connection (screw means 18) of the fixed and movable adjustment tables 16, 17, the play in the screwed state is 1/1000 to 5/100.
The one set to an accuracy of 0 is used. In the machine base installation temporary core adjustment step, the height and level of the machine base 6 are adjusted in a predetermined manner between the upper surface of the foundation concrete 2 and the machine base 6 of the blower 1. The surface height fine adjustment device 13 with the helical rotation operation mechanism is installed at a plurality of locations (near the formation site of the present packer 7 described later), and the surface height low fine adjustment device 13 with the helical rotation operation mechanism is used. The horizontality of the machine base 6 and a predetermined height level are finely adjusted and set. By individually operating the surface height fine adjustment device 13 having each of the helical rotation operation mechanisms, the work of adjusting the horizontality and the height level of the machine base 6 can be performed easily and quickly. In this state, the height adjustment member 12 (taper liner) on the temporary packer 5 is adjusted to the height level set by the surface height fine adjustment device 13 having the helical rotation operation mechanism, and the height is adjusted. The upper surface of the adjustment member 12 (taper liner) is brought into contact with the lower surface of the machine base 6. After the machine base 6 has been adjusted and set to a horizontal level and a predetermined height level as described above, the surface height fine adjustment device 13 with the helical rotation operating mechanism is removed and the temporary core is adjusted. After receiving the inspection, after passing the inspection, concrete 9 for anchor bolt fixing is filled and poured into the metal bottomed formwork 4, ie, the anchor bolt setting holes, and the filled and poured concrete is cast. 9 fixes the anchor bolt 3 in a vertical state. Then, on each concrete 9 for fixing the anchor bolts, the present packer 7 is placed between the upper surface of the concrete 9 at the position where the anchor bolts 3 are sandwiched and the base 6 of the blower 1 without shrinkage. The cement is poured into a metal split mold so as to be poured into the metal mold, and the lock base 11 is placed on the non-shrinkage cement in the same manner as the temporary packer 5 described above.
This is formed by placing a (referred to as a main packer placing step). Adjustment of the lock base level of the present packer 7 is performed by adjusting a pair of heights between the lower surface of the machine base 6 already mounted on the temporary packer 5 and having completed the temporary centering and the lock base 11a. This is performed by inserting the member 12a (taper liner) and sliding the height adjusting member 12a (taper liner) to push the lock base 11a into the main packer 7. That is, the lock base (parallel liner) 11
A height adjustment member 12a (taper liner) having opposing sliding tapered surfaces configured similarly to the height adjustment member 12 used for the temporary packer 5 is placed on a.
By sliding the height adjusting member 12a (taper liner), the upper surface of the height adjusting member 12a (taper liner) is brought into contact with the lower surface of the machine base 6 while pushing the lock base 11a into the main packer 7. (See FIGS. 6 and 7). In this case, until the packer 7 is hardened, the upper surface level of the lock base (parallel liner) 11a is parallel to the lower surface of the machine base 6 of the blower 1 to be installed, and the height adjusting member 12a applies The check is made so that "no backlash" occurs. At this time, the verticality of the anchor bolt 3 is also set to be vertical. Then, after the main packer 7 is cured,
The centering adjustment is performed by the height adjusting member 12 on the lock base of the packer 7, and tightened by a nut or the like screwed to the anchor bolt 3. That is, this centering adjustment
As described above, this is performed as a precision adjustment operation of sliding the height adjustment member 12 while tightening a nut or the like screwed to the anchor bolt with a torque wrench. After these adjustment operations are completed and the final inspection is passed, the metal split formwork of the present packer 7 is dismantled and extracted, and the lock base 11 and the height adjustment of each temporary packer 5 are adjusted. All the members 12 are fixed by welding. After that, a cinder concrete 19 is poured to the upper surface of the machine base 6 installed on the base concrete 2 to finish the iron, and here, in the underground space,
A blower 1 constituting an air conditioner or the like is installed on a foundation concrete 2. In the above-described embodiment, the installation positions and the numbers of the temporary packers 5 and the actual packers 7 when the machine base 6 is installed are not limited to those shown in the drawings. The surface height fine adjustment device 13 with a mechanism is not limited to the illustrated one. According to the first aspect of the present invention, when adjusting the height and levelness of the machine base, a plurality of spirals are formed on the foundation concrete at predetermined places near the place where the packer is to be placed. Place a surface height fine adjustment device with a rotation operation mechanism,
By adjusting and setting the height and level of the machine base with the individual surface height fine adjustment tools with the spiral rotation operation mechanism, the installation level of the air conditioning equipment and the like can be adjusted very easily, and the work can be performed. It is possible to improve the efficiency and the installation accuracy, to save the labor and time required for the work as much as possible, and to shorten the work period of the whole work as much as possible. In adjusting the height and level of the machine base, it is difficult to adjust the lock base level 1/100 to 2/100, which is a reference for the centering adjustment, by a jack or the like. Severe adjustment is easily ensured by arranging the surface height fine-adjustment devices with the spiral rotation operation mechanism for the number of units for which the withstand load has been calculated, and using the individual surface height low-fine adjustment devices with the spiral rotation operation mechanism. be able to.
