Abstract
Description
[Technical Field]
[0001] The present invention relates to a method for installing a forced shower in a recessed position in a wall. [Background technology]
[0002] Pools at recreational facilities, schools, and other facilities are sometimes equipped with forced showers, which are used by users to wash off dirt and sand from their feet and to wash their bodies before entering the pool.
[0003] A forced shower consists of a U-shaped pipe and a water outlet located in the middle of the pipe. Usually, one end of the pipe is embedded in a first wall such as a reinforced concrete wall, while the other end of the pipe is embedded in a second wall opposite the first wall.
[0004] A known method for installing a forced shower is to transport a shower unit that has been manufactured in advance at a factory to the installation site, fix the shower unit to a concrete foundation with anchor bolts, etc., and then install water supply piping and electrical wiring on-site (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-45302 Summary of the Invention [Problem to be solved by the invention]
[0006] Furthermore, a conventional method for installing a force shower is to construct the first and second walls and bury the pipes in both walls at the installation site without using a shower unit. To explain this method in more detail, first, a formwork for forming the two walls is made in advance. Then, both ends of the pipe of the force shower (i.e., the portions to be buried in the two walls) are placed in the formwork, and the position and horizontality (level) of the force shower are adjusted appropriately, and then a filler material such as concrete is poured into the formwork. In other words, the framework construction for forming the two walls and the construction of burying the force shower in both walls are carried out simultaneously. Then, by dismantling the formwork after the filler has solidified, the force shower can be installed while the two walls are being constructed.
[0007] However, with this method, the forced shower head is prone to tilting when the filler is poured, which can lead to improper positioning and horizontality of the forced shower head, and this improper state cannot be corrected later. Even if the forced shower head is temporarily fixed in place by some method before pouring the filler, it is necessary to firmly fix it to protect against strong winds, and then remove the temporary fixing material after the filler has solidified, which is an extremely time-consuming and cumbersome process. Furthermore, with the above method, the forced shower head must be prepared in advance when the framework construction work to form both wall sections is carried out, which is not desirable in terms of construction efficiency.
[0008] Furthermore, when using a forced shower with pipe sections that can be separated along the length, if only the sections of the pipe section that will be embedded in both wall sections are prepared in advance, and after these sections are embedded in both wall sections, the components of the pipe section are connected in series, then there is no need to prepare the entire forced shower in advance when constructing the framework to form the wall sections, and this can prevent a decrease in construction efficiency to some extent.However, in order to connect the components, it is necessary to provide flanges (brims) for connection on the components or to weld the components together, and the presence of flanges and welds visible on the exterior of the forced shower may lead to a decrease in the appearance quality (appearance).
[0009] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a method for installing a forced shower that can more easily and reliably install a forced shower in an appropriate position and with appropriate horizontality, and that eliminates the need to prepare the forced shower in advance when forming the wall section. [Means for solving the problem]
[0010] The following describes each of the means suitable for achieving the above object, with specific effects of the corresponding means added as necessary.
[0011] Means 1. A forced shower having a U-shaped pipe and a water outlet provided in the middle of the pipe is installed in such a way that one end of the pipe is attached to a first wall that stands on a predetermined floor, while the other end of the pipe is embedded in a second wall that faces the first wall across the floor, a sleeve insertion step of inserting the other end portion of the pipe portion into a cylindrical sleeve that is embedded in the second wall portion and opens at the top and bottom; a one-end fixing step of fixing a plate-like plate attached to one end of the pipe portion to a horizontal flat surface provided on an upper portion of the first wall portion; a temporary fixing step of temporarily fixing the other end portion of the pipe portion to the sleeve; an other end fixing step of fixing the other end of the pipe portion protruding from the lower opening of the sleeve to the floor portion; and a filling step of filling a predetermined filler material between the sleeve and the pipe portion.
[0012] According to the above-mentioned method 1, a first wall having a substantially horizontal flat surface at the top and a second wall having a cylindrical sleeve with openings at the top and bottom embedded therein are formed in advance, and then the other end of the pipe is inserted into the sleeve. Next, a plate attached to one end of the pipe is fixed to the flat surface of the first wall. Next, after checking the position and horizontality of the forced shower, the other end of the pipe is temporarily fixed to the sleeve. This ensures that the position and horizontality of the forced shower are appropriate, while restricting the tilt and movement of the forced shower. Next, the other end of the pipe protruding from the lower opening of the sleeve is fixed to the floor, and a filler material (e.g., mortar) is filled between the sleeve and the pipe, completing the installation of the forced shower.
[0013] Therefore, according to the above-mentioned means 1, one end of the pipe part is fixed and the other end of the pipe part is temporarily fixed, and then the other end is fixed, and after that fixing, the filler is filled, so that the forced shower can be installed more easily and reliably with the position and horizontality appropriate.
[0014] Furthermore, according to the above-mentioned means 1, there is no need to prepare a forced shower head in advance when forming both wall sections. Therefore, it is possible to more reliably prevent a decrease in the efficiency of the framework construction work for forming the wall sections. Furthermore, since it is not necessary to use a pipe section that can be separated along the longitudinal direction to prevent a decrease in workability in the framework construction work, it is also possible to prevent a decrease in the appearance quality (appearance) due to the presence of flanges or welded parts in the forced shower head.
[0015] Means 2. In the one end fixing step, the plate is fixed to the flat surface corresponding to the bottom of a notch provided in the upper part of the first wall portion, The installation method of the forced shower according to means 1, characterized in that it includes a repair process of filling the notch after the one end fixing process.
[0016] According to the above-mentioned means 2, by filling the notch provided in the first wall portion in the repair process, it is possible to prevent one end of the plate or pipe portion from being exposed to the outside, which makes it possible to protect one end of the plate or pipe portion and to obtain better appearance quality (attractive appearance).

[0018] An embodiment will be described below with reference to the drawings. Fig. 1 is a schematic perspective view showing a forced shower 1 and a structure 100 to which it is attached, Fig. 2 is a schematic front view of the forced shower 1, etc., and Fig. 3 is a cross-sectional view taken along line JJ in Fig. 1. The forced shower 1 is installed corresponding to the entrance and exit of a swimming pool in a facility such as a resort or school. Before describing the forced shower 1, the structure 100 will first be described.
[0019] The structure 100 is a reinforced concrete (RC) structure with reinforcing bars embedded inside, and has a floor 101, a first wall 102, and a second wall 103 (the reinforcing bars are not shown in Figure 3 etc.). The floor 101 and both wall sections 102, 103 of the structure 100 are located above ground, and the portion below the floor 101 is located underground (underground).
[0020] The floor 101 constitutes the floor for the user of the forced shower 1, and is formed with a predetermined drain outlet 101a. The upper surface of the floor 101 is a gentle slope that gradually descends toward the drain outlet 101a, and the drained water passes through the drain outlet 101a and flows into a drain basin (not shown).
[0021] The first wall 102 and the second wall 103 are walls that are erected on the floor 101 and that face each other across the floor 101. The upper surfaces of the first wall 102 and the second wall 103 are inclined surfaces that gradually decline toward the floor 101 side, so that water adhering to the upper surfaces is guided toward the floor 101 side. A cylindrical sleeve 41 that extends vertically is embedded in the second wall 103, and the inside of this sleeve 41 is filled with a predetermined filler 42 (for example, mortar).
[0022] Furthermore, the structure 100 has a pit 104, which is an underground space located below the floor 101, and a water supply pipe and the like (not shown) are arranged in this pit 104. The water supply pipe is connected to the forced shower 1 and is responsible for supplying water to the forced shower 1.
[0023] The structure 100 is constructed by framework construction work that is carried out before the installation work of the forced shower 1. Here, the first wall 102 constructed by framework construction has a notch 102a in its upper part, and the surface corresponding to the bottom of the notch 102a is a horizontally flat surface 102b (see Figure 6, etc.). The second wall 103, which is constructed in the same way, has a sleeve 41 buried therein that is empty (i.e., not filled with filler 42), with the upper end of the sleeve 41 opening above the second wall 103 and the lower end of the sleeve 41 opening below the floor 101 (i.e., in the pit 104). The installation work of the forced shower 1 is carried out on the structure 100 with both walls 102, 103 in this state.
[0024] Next, we will explain the forced shower 1. The forced shower 1 is used to wash the user's body by spraying water from above the user and then letting it fall. The forced shower 1 is mainly made of a specific metal (such as stainless steel), and has a pipe section 2 and a water outlet section 3.
[0025] The pipe section 2 is U-shaped (arch-shaped), supports the water discharge section 3 above the user, and forms a water supply path for the water discharge section 3. The pipe section 2 includes a first vertical pipe section 21 and a second vertical pipe section 22 that each extend vertically, and a horizontal pipe section 23 that connects the upper ends of the vertical pipe sections 21, 22 together.
[0026] The first vertical pipe section 21 is a cylindrical part that constitutes one end side portion of the pipe section 2. A flat plate 43 is attached to the lower end of the first vertical pipe section 21 in a state perpendicular to the extension direction of the first vertical pipe section 21, and this plate 43 is fixed to the upper part of the first wall section 102 (particularly the flat surface 102b corresponding to the bottom of the notch 102a) by, for example, anchor bolts 47. In this manner, the lower end of the first vertical pipe section 21 is attached to the first wall section 102. Note that in this embodiment, the notch 102a is eventually filled, so that the plate 43 and the lower end of the first vertical pipe section 21 are not exposed on the surface of the first wall section 102.
[0027] The second vertical pipe section 22 is a cylindrical portion constituting the other end of the pipe section 2. The second vertical pipe section 22 is inserted into the sleeve 41, and the lower end of the second vertical pipe section 22 (i.e., the other end of the pipe section 2) protruding into the pit 104 is fixed to the floor section 101. The above-mentioned water supply pipe is connected to the lower end of the second vertical pipe section 22 protruding from the floor section 101. In this embodiment, the second vertical pipe section 22 is fixed to the floor section 101 by, for example, sandwiching the second vertical pipe section 22 between a fixing base section 45, such as an L-shaped angle, fixed to the floor section 101 and a predetermined U-bolt 46 (see FIG. 4). Of course, other methods may be used to fix the lower end of the second vertical pipe section 22 (the other end of the pipe section 2) to the floor section 101.
[0028] As described above, the filler 42 is filled between the outer peripheral surface of the second vertical pipe section 22 and the inner peripheral surface of the sleeve 41. As a result, the second vertical pipe section 22 (i.e., the other end side portion of the pipe section 2) is embedded in the second wall section 103.
[0029] The horizontal pipe section 23 is a cylindrical part that constitutes the middle section of the pipe section 2. The horizontal pipe section 23 has a shape in which the middle section extends horizontally, excluding the connection points (curved sections) with the two vertical pipe sections 21, 22. The water discharge section 3 is provided so as to protrude downward from the longitudinal center of the middle section.
[0030] A predetermined closure plate 24 is provided slightly closer to the first vertical pipe section 21 than the center in the horizontal pipe section 23. This allows the internal space of the pipe section 2 from the other end of the pipe section 2 (the lower end of the second vertical pipe section 22) to the closure plate 24 to function as a water supply passage for the water discharge section 3.
[0031] Furthermore, the pipe portion 2 in this embodiment is not one whose components can be separated along the longitudinal direction, and does not have flanges (brim-shaped portions) or welded portions for connecting the components together. Therefore, the portion of the pipe portion 2 from the upper surface of the first wall portion 102 to the upper surface of the second wall portion 103, i.e., the portion visible to the user, has a substantially constant outer diameter along the longitudinal direction, resulting in a good appearance.
[0032] The water discharger 3 is a section that sprays water supplied through the pipe section 2 downward. In this embodiment, the water discharger 3 is configured to switch between spraying and stopping water discharge in response to an output signal from a human presence sensor (not shown) provided on the first wall section 102 or the second wall section 103, for example. Of course, the water discharger 3 may be configured to switch between spraying and stopping water discharge using a manually operable operating section (for example, an operating handle).
[0033] Next, with reference to Fig. 5 etc., the installation method of the above-mentioned forced shower 1 will be explained. Note that prior to the installation of the forced shower 1, framework construction is carried out in advance to construct a structure 100 having a floor 101 and both wall sections 102, 103 etc. At this stage, a notch 102a is provided in the first wall section 102, and the bottom of this notch 102a forms a horizontally flat surface 102b. Furthermore, a sleeve 41 that opens at the top and bottom is embedded in the second wall section 103. Furthermore, prior to the installation work of the forced shower 1, a plate 43 is attached to one end of the pipe section 2.
[0034] First, in a sleeve insertion step of step S1, the other end side portion (second vertical pipe portion 22) of the pipe portion 2 is inserted into the sleeve 41 (see FIG. 6).
[0035] Furthermore, in the one end fixing process of step S2, the plate 43 is fixed to the flat surface 102b, which is on the upper part of the first wall portion 102 and corresponds to the bottom of the notch 102a, using anchor bolts 47 or the like (see FIG. 7). As a result, one end of the pipe portion 2 is attached to the first wall portion 102 with the first vertical pipe portion 21 extending vertically.
[0036] Next, in the temporary fixing process of step S3, after confirming that the position and horizontality of the horizontal pipe section 23 (particularly the middle section) are appropriate, the second vertical pipe section 22 (the other end side section of the pipe section 2) is temporarily fixed to the sleeve 41 while maintaining the position and horizontality in an appropriate state (see FIG. 8). As a result, the horizontal pipe section 23 (particularly the middle section) is in an appropriate position and horizontality and will not move easily. Note that temporary fixing can be performed, for example, by driving a predetermined wedge 51 between the sleeve 41 and the second vertical pipe section 22. It is preferable to adjust the gap between the outer circumferential surface of the second vertical pipe section 22 and the inner circumferential surface of the sleeve 41 using the wedge 51 to more reliably ensure that the position and horizontality of the forced shower 1 are appropriate.
[0037] Next, in the other end fixing process of step S4, the lower end of the second vertical pipe section 22 (the other end of the pipe section 2) protruding from the lower opening of the sleeve 41 is fixed to the floor section 101 using the fixing base section 45 and the U-bolt 46 (see FIG. 9). As a result, both ends of the pipe section 2 are fixed with the horizontal pipe section 23 in an appropriate position and horizontality. Note that, in order to more appropriately position and horizontality the forced shower 1, when fixing the lower end of the second vertical pipe section 22, the position of the lower end of the second vertical pipe section 22 in the vertical and horizontal directions may be adjusted. This position adjustment may be performed after removing the wedge 51.
[0038] In the subsequent filling step S5, a filler 42 is filled between the sleeve 41 and the pipe section 2 (second vertical pipe section 22) (see FIG. 10 ). By filling the filler 42, the second vertical pipe section 22 (the other end side portion of the pipe section 2) is embedded in the second wall section 103. In this embodiment, the filler 42 is also filled above the sleeve 41, so that the sleeve 41 is not exposed on the upper surface of the second wall section 103. Prior to filling, the wedge 51 is removed, and the lower opening of the sleeve 41 is closed using a sheet-like filler receiving member (not shown) (e.g., A-PAT (registered trademark) or the like).
[0039] Finally, in the repair process of step S6, the cutout 102a is filled with a filler such as mortar. As a result, the plate 43 and one end of the pipe section 2 are embedded in the first wall section 102, and the installation of the forced shower 1 is completed. Note that the repair process of step S6 may be performed after the one end fixing process (step S2), and does not necessarily have to be performed after the filling process (step S5). After the installation of the forced shower 1 is completed, necessary work such as connecting a water supply pipe to the pipe section 2 (the lower end of the second vertical pipe section 22) is carried out.
[0040] As described above in detail, according to this embodiment, one end of the pipe part 2 is fixed and the other end of the pipe part 2 is temporarily fixed, and then the other end is fixed, and after that fixing, the filler 42 is filled, so that the forced shower 1 can be installed more easily and reliably with the position and horizontality appropriate.
[0041] Furthermore, there is no need to prepare the forced shower 1 in advance when forming the structure 100 (walls 102, 103, etc.). Therefore, it is possible to more reliably prevent a decrease in efficiency in the framework construction work for forming the structure 100. Furthermore, since it is not necessary to use pipe parts that can be separated along the longitudinal direction in order to prevent a decrease in workability in the framework construction work, it is possible to prevent a decrease in the external appearance quality (appearance) due to the presence of flanges and welded parts on the forced shower 1.
[0042] In addition, by filling the notch 102a provided in the first wall portion 102 in the repair process of step S6, it is possible to prevent the plate 43 and one end of the pipe portion 2 from being exposed to the outside. This makes it possible to protect the plate 43 and one end of the pipe portion 2, and also to obtain better appearance quality (good looks).
[0043] The present invention is not limited to the above-described embodiment, and may be implemented as follows: Of course, other applications and modifications not exemplified below are also possible.
[0044] (a) In the above embodiment, the pipe section 2 does not have flanges or welded parts. However, although this may be somewhat disadvantageous in terms of external appearance quality (appearance), it is also possible to use a pipe section 2 that has flanges or welded parts. Even in this case, by adopting the above-mentioned installation method for the forced shower 1, the forced shower 1 can be installed more easily and reliably with the correct position and levelness.
[0045] (b) In the above embodiment, the first wall portion 102 has the cutout 102a, and the plate 43 is fixed to the flat surface 102b that is the bottom of the cutout 102a. In contrast, if the upper surface of the first wall portion 102 is a horizontal flat surface, the plate 43 may be fixed to this flat surface without providing the cutout 102a. In this case, the repair step (step S6) for filling the cutout 102a is not required. [Explanation of symbols]
