Description

  The present invention relates to an installation structure of a support column for a water stop plate that blocks a building opening, blocks water from the outside, and supports a water stop plate for preventing water from entering the inside. Are placed behind the water blocking plate to prevent the water blocking plate from being damaged if the water blocking plate is bent to the inside of the building by water pressure and the water blocking plate can not be secured. The present invention relates to an installation structure of a water blocking plate support column to be improved.

  As the structure and configuration of the water blocking plate, for example, those in which the water blocking plate is held in a U-shaped frame as is seen in Patent Documents 1 and 2 and those in which the water standing plate is erected are known. These conventional waterstops are usually stored in a separate place and are often transported by users in the event of an emergency and installed at the building opening, so the size, weight, etc. must be equivalent to human power. I must.

  For this reason, priority is given to a lightweight structure, and the case where water-resistant pressure is insufficient is occasionally seen. Moreover, if the frontage of a building opening is wide, the amount of deflection of the water stop plate installed there inevitably increases. Furthermore, since it is difficult to carry by humans when the width dimension reaches several meters, it is necessary to install a plurality of waterstop plates with a certain width dimension in the frontage direction, and the waterstop of the connection part at that time In addition, a supporting force for improving the water pressure resistance that can prevent opening and breakage is required.

  However, in order to solve the above-mentioned problem, it is necessary to erect a water-stop plate support column on the floor surface of the opening area, and to reduce the deflection due to water pressure and improve the water-stop performance of the connection portion of the water-stop plates. However, it was urgent to provide a method for installing a water blocking plate support column that can withstand extremely high water pressure and prevent the tilt and breakage of the water blocking plate.

  Then, this invention is created in view of the said problem, provides the installation structure of the support pillar for water blocking boards which enables installation of the support column for water blocking boards simply and easily while having high water pressure resistance etc. The purpose is to do.

In order to solve the above problems, the present invention is
An installation structure of a water blocking plate support column for supporting a water blocking plate for closing an opening of the building to stop water flowing from the outside, comprising:
The water stop plate support column is fitted in a fistula formed by indenting the floor surface of the opening area at the lower end side, and has a water stop plate contact surface that supports and supports the water stop plate above. The lower end side of the support column for water blocking plate and an auxiliary tool to be in contact with the weir are fitted.
An installation structure of a water blocking plate support column characterized by

  In the installation structure of the water blocking plate support column of the present invention having such a configuration, the water blocking plate support column is fitted and fixed in the hole, so that it has high water pressure resistance and is fitted with an auxiliary tool. Therefore, the support pillar for the water stop plate is securely fixed in the fistula, and a close contact surface can be formed between the support pillar for the water stop plate and the fistula, and good water stoppage can be obtained. . Furthermore, originally, in order to achieve fixation and close contact between the well and the water blocking plate support column, a gap should not occur between the water blocking plate supporting column and the well but the well By fitting the auxiliary tool between the water plate support column (inside of the building), the water blocking plate support column can be reliably fixed in the stoma. The “auxiliary tool” in the present invention is fitted between the water hole and the water blocking plate support column, and is used to securely fix and closely contact the water blocking plate support column in the water hole. It is a wedge material and can also be said to be a backup material or a fitting material that backs up such fixing and adhesion.

Further, in the installation structure of the above water blocking plate support column of the present invention,

The water stop plate support pillar is fitted in the hole, and includes an A1 contact flange surface that contacts the flange surface of the hole and an A2 contact flange surface that contacts the auxiliary tool,
The auxiliary tool is fitted in the shaft hole, and the B2 contact flange surface that contacts the flange surface of the hole and the B1 contact flange surface that contacts the A2 contact flange surface of the water column support pillar. It is desirable to provide.

  In the installation structure of the support pillar for the water stop plate of the present invention having such a configuration, the water stoppage is improved because the above-described surfaces come into contact with each other, and water enters from between the fistula and the support pillar for the water stop plate. This can be suitably prevented.

  In the installation structure of the water stop plate support column of the present invention, the A1 contact flange surface and the A2 contact flange surface of the water stop plate support column are the water stop plate support column. Preferably, the B1 contact wedge surface and the B2 contact wedge surface of the auxiliary tool are disposed on the opposite surface of the auxiliary tool. That is, in the water blocking plate support column, the A2 abutment wedge surface is located on the opposite side of the A1 abutment wedge surface, or the A1 abutment wedge surface and the A2 abutment wedge surface are back-to-back It is located so as to face. In the auxiliary tool, the B2 abutment wedge surface is located on the opposite side of the B1 abutment wedge surface, or the B1 abutment wedge surface and the B2 abutment wedge surface face back to back. Located in.

  In the installation structure of the water-stop plate support pillar of the present invention having such a configuration, since the contact flange surfaces are arranged in the same direction, the generation of a gap can be prevented and the water-stop performance can be improved. In addition, when the arrangement direction of each contact ridge surface matches the longitudinal direction of the building opening (building outside and building inside), and the auxiliary tool is located behind the building opening, for water blocking board by water pressure The upper end side of the support column is pushed backward, and water pressure is applied so that the water stop plate support column is inclined toward the inside of the building. Thereby, since the lower end side of the support pillar for water stop plates is closely contacted by the ridge surface of the fistula, water stop can be further improved.

  Further, in the installation structure of the water blocking plate support column according to the present invention, it is preferable that the A1 contact wedge surface of the water blocking plate support column is made of a water blocking material.

  In the installation structure of the support pillar for the water stop plate of the present invention having such a configuration, if the dimensions of the auxiliary tool are set so that the flexible water stop material compresses with a compression allowance that exhibits a water stop effect. In addition to improving the water-stopping performance of the water-stop plate support column and the fistula, when fitting the water-stop plate support column, the water-stop material may be damaged or the water-stop material may be Problems such as peeling from the fistula can be prevented. That is, there is a concern that the waterproof and easy-to-scratch water-stopping material may be damaged to fit the water-stop support pillar in close contact with the fistula, but in the installation structure of the water-stop support pillar of the present invention, After the support column for water blocking plate is fitted with a margin, the auxiliary tool is fitted and the support column for water blocking plate and the weir are brought into close contact, so that the concern can be resolved.

  Moreover, in the installation structure of the support pillar for water stop boards of said this invention, it is desirable to provide the press surface which receives a press above the said auxiliary tool.

As shown in FIG. In the description of the present embodiment, the upper end side of the water blocking plate support pillar 1 is P1, and the lower end side is P2.

  As shown in FIGS. 2 (a) and 2 (b), the water-stop plate support column 1 used in the present embodiment is fixed to a substantially rectangular parallelepiped column body 23 and the upper end of the column body 23, so that the operability of the user is improved. And a water blocking material 19 for preventing the entry of water into the fistula 3, and a projection 27 provided on the bottom plate 29 of the column 23.

  The column body 23 is a substantially rectangular parallelepiped component formed of a metal material having corrosion resistance such as stainless steel or aluminum, a resin material having high rigidity, or the like. The dimensions of each part may be appropriately determined in consideration of the supportability of the water blocking plate 107, water pressure resistance, handleability, etc. For example, the front width dimension L4 is about 5 cm to 50 cm, and the side width dimension L5 is More preferably, the height L6 is set in the range of about 10 cm to 120 cm.

  In addition, it is desirable that a range of 10 cm to 50 cm from the lower end side P2 be a fitting area for the below-described fistula 3 and that the dimension position be a fitting upper end edge P3.

  The columnar body 23 used in the present embodiment adopts a substantially rectangular parallelepiped (a cross-sectional shape is a rectangle) as described above, but is not limited to this. For example, the cross-sectional shape is an oval, a polygon, or a U shape. Alternatively, it may be C-shaped (substantially the same cross-sectional shape as the lip groove steel). Further, the inside may be solid or hollow. The water stop plate support column 51 employing the column body 23 having a C-shaped cross-sectional shape will be described in detail later.

  A top plate 31 is disposed on the upper end side P1 of the column body 23, and a gripping portion for a user to grip and operate the water blocking plate support pillar 1 on the outer side surface of the top plate 31. 25 are arranged. Further, a bottom plate 29 is disposed on the lower end side P2 of the column body 23, and a plurality of projections 27 which abut on the bottom surface 43 of the hole 3 to be described later are disposed on the outer surface of the bottom plate 29. It is done. As shown in FIG. 3, the bottom plate 29 is provided with a plurality of (four in the present embodiment) protrusions 27 having the same shape, which are respectively disposed near the corners of the bottom plate 29. Since there is a concern about unintended entry of gravel or the like, the hole 3 is not brought into contact with the bottom surface 43 of the hole 3 and the bottom plate 29 of the column body 23, but is brought into substantially point contact via the protrusion 27 and the like. The inclination can be further suppressed and stabilized. FIG. 3 is a bottom view of the water blocking plate support column 1 when the bottom plate 29 of the column body 23 is viewed from below.

  The front surface of the column 23 is a water stop plate abutting surface 7 whose upper end side P1 is in contact with the water stop plate 107, and the lower end side P2 includes a water stop material 19 described later. This surface is an A1 contact saddle surface 11 that contacts the flange surface 9 of the hole 3. In addition, the back surface of the column body 23 is an A2 contact saddle surface 13 whose lower end side P2 is in contact with an auxiliary tool 5 described later.

5. Installation Method of Water Sealing Plate 107 Next, referring to FIGS. 7, 8 and 9, installation of the water sealing plate 107 using the water blocking plate support pillar 1, the weir 3 and the auxiliary tool 5. The method will be described in detail. FIG. 7 is a schematic view showing a situation where the water stop plate support pillar 1 and the auxiliary tool 5 are fitted in the fistula 3, and FIG. 8 is a water stop plate support pillar 1 fitted in the fisthole 3. FIG. 9 is a cross-sectional view of the auxiliary tool 5 from the building interior side 103 to the building exterior side 105 direction, and FIG. 9 is a plan view of the floor 109 as viewed from above with the water stop plate 107 installed in the building opening 101.

  First, as shown in FIG. 7, after removing the lid 41 fitted in the hole 3 and opening the hole 3, the holding part 25 of the water-stop plate support pillar 1 is held and the water-stop plate Support column for water blocking plate in the weir 3 so that the A1 contact weir surface 11 abuts on the weir surface 9 located on the building exterior side 105 of the weir 3 while making the contact surface 7 face the building exterior side 105 1 is fitted.

  Subsequently, the gripping portion 33 of the auxiliary tool 5 is gripped, the B1 contact saddle face 15 is brought into contact with the A2 contact saddle face 13 of the water blocking plate support pillar 1, and is located on the building interior side 103 of the hole 3. The auxiliary tool 5 is fitted on the rear side (building interior side 103) of the water blocking plate support pillar 1 in the hole 3 so that the wedge surface 9 and the B2 abutment wedge surface 17 abut. In this case, the fitting can be easily performed by pressing the auxiliary tool 5 pressing surface 35. In addition, at the first stage of this fitting, the tip portion 37 formed in a tapered shape is inserted into the tunnel 3 (A2 contact ridge surface 13 of the support column 1 for water blocking plate and the building interior side of the portal 3) The auxiliary tool 5 can be easily fitted in the fistula 3 by being inserted between the rib surface 9 positioned at 103) and guiding the whole.

  As shown in FIG. 8, by fitting the auxiliary tool 5 in the fistula 3, the water-stop plate support pillar 1 is squeezed toward the outside 105 of the building, so that the water-stop material 19 is pressed. The Thereby, the fitting position of the water-stop plate support pillar 1 with respect to the fistula 3 is determined, and the water-stop plate support pillar 1 is surely installed in the fistula 3. The gap between the wedge surface 9 positioned in the direction and the A1 contact wedge surface 11 is reliably sealed, and a high water blocking function (water tightness) can be exhibited, and the water blocking plate support pillar 1 is touched as described later. Even if the water stop plate 107 is installed in contact with the water stop plate 107 and the water stop plate 107 is about to fall down to the inside 103 of the building due to water pressure, the water stop plate support pillar 1 is pressed and installed in the fistula 3. Therefore, the water stop plate 107 can be supported without inclining.

  With the above procedure, the water blocking plate support pillar 1 is securely fixed, and the water blocking plate 107 can be installed at the building opening 101 via the water blocking plate support pillar 1. As shown in FIG. 9, the water stop plate 107 is transported between the opening edges 111 at both ends forming the building opening 101 and the water stop plate support pillar 1 and is erected on the floor surface 109. Each end of the building opening 101 in the frontage direction is fixed to the opening edge 111 and the water blocking plate support pillar 1. A known method can be used to fix the end in the direction of the opening of the water blocking plate 107 and the opening edge 111 or the support post 1 for water blocking plate, and a toggle shown in, for example, JP-A-2017-160693. What is necessary is just to fix using a type | mold metal fitting.

  The water blocking plate 107 used is, for example, a substantially rectangular plate-like member having a substantially parallel first surface (front surface) and a second surface (rear surface) and having a predetermined thickness. It is preferable to use various materials as long as the above functions are achieved and the effects of the present invention are not impaired. It may be made of resin or metal, and for example, the main part of the water blocking plate may be made of resin and a metal frame material may be formed on the periphery, or at least the first You may have the hollow structure which has the surface and the 2nd surface, and connected between them by the crosspiece structure.

  On both ends of the water stop plate 107 in the front end direction (for example, the rear surface of both ends of the front end direction) and on the lower end of the water stop plate 107 (the surface in contact with the floor surface 109), a water stop packing extending in the height direction and the horizontal direction ( (Not shown) is preferably provided. The water blocking packing can be made of a rubber material, a resin material, a resin foam, an air bag body, etc., and when water pressure is applied to the water blocking plate 107, it elastically deforms to receive the water pressure, and the water blocking plate It has a function as a so-called sealing material or packing that seals so as not to leak water from between the opening edge 111 and the floor surface 109 (here, a water blocking material provided on the water blocking plate 107 For the sake of easy distinction from the water-stopping material of the support pillar 1 for plates, the “water-proof packing” is described for convenience, but the water-stopping packing and the water-stopping material of the support pillar 1 for the waterstop plate are essential. It is needless to say that the same material and the same kind may be used.

  The lower part of the water blocking plate supporting column 1 is in contact with the water blocking packing disposed at the lower end of the installed water blocking material 107 because the water blocking material 19 protrudes upward from the floor surface 109 as described above. The water-stopping property in the vicinity of the lower part of the support pillar 1 for the water-stopping plate is improved.

  In addition, although there is a so-called groove formed by the presence of the above-described lid contact surface 39 on the outer periphery of the hole 3 in which the water blocking plate support pillar 1 is fitted, Since the water stop packing disposed at the lower end of the water stop plate 107 covers the portion (the groove located on the building external side 105 adjacent to the water stop material 19) from the top, the water flows from the building external side 105. Intrusion into the lid contact surface 39 can be prevented. Even when two water stop plates 107 are installed in the building opening 101 via the water stop plate support pillar 1 as in this embodiment, the water stop packing of the water stop plate 107 covers the groove from above. Similarly, the water-stopping property can be ensured, but the gap between the two water-stopping plates 107 may be filled and the lid abutting surface 39 may be installed so as to cover all the portions located on the building exterior side 105. Moreover, if the water stop packing is provided on the end face where both of the two water stop plates 107 abut, the water stop can be performed more reliably.

6. The installation aspect of the other water stop board 107 using the support column 1 for water stop boards This invention can also take the installation aspect of the other water stop board 107 using the support column for water stop boards besides the above-mentioned. . The installation aspect of the other water stop board 107 using the support pillar for water stop boards is demonstrated using FIG. 10 (a) and (b). FIGS. 10 (a) and 10 (b) are diagrams showing the installation mode of the other water blocking plate 107 using the water blocking plate support column, and FIG. 10 (b) is a plan view showing an aspect corresponding to the building opening 101 of the inclined wall surface.

  In the case of corresponding to the projected corner shaped building opening 101 as shown in FIG. 10A, for example, a substantially pentagon having a plane substantially parallel to both opening edges 111 at the intersection on the extension line of both opening edges 111 If the water blocking plate support column 201 having the cross sectional shape is installed, two water blocking plates 107 can be installed in the building opening 101 via the water blocking plate support column 201 to perform water blocking. .

  In addition, in the case of corresponding to the building opening 101 provided on the inclined wall surface as shown in FIG. 10B, the water stop plate abutment surface 7 of the water stop plate support column 1 is substantially parallel to the inclined wall surface. The water stop can be performed by installing the water stop plate 107 in the building opening 101 through the support pillar 1 for the water stop plate.

  Furthermore, as shown in FIG. 10 (c), one water blocking plate 107 is installed at the building opening 101 via the water blocking plate support pillar 1, and the substantially central portion of the water blocking plate 107 from the building interior side 103. It may be possible to prevent bending by supporting and improve water pressure resistance and water stoppage.

  As described above, if the shape and the arrangement method of the water blocking plate support pillars are changed according to the shapes of the building opening 101 and the opening edge 111, it can be widely handled according to the aspect of the building opening 101.

7). Other Water Barrier Plate Support Columns and Auxiliary Tools Next, other water barrier plate support columns 51 will be described using FIG. 11 and FIGS. 14 (a) and 14 (b). FIG. 11 is a perspective view showing the structure of the water blocking plate support pillar 51. As shown in FIG. 14 (a) and 14 (b) are diagrams showing a modification of the water blocking plate support column 51, and FIG. 14 (a) is provided with an I-shaped projection 83 on the water blocking plate contact surface 57. FIG. 14B is a cross-sectional view of the water blocking plate support column 51 provided with a T-shaped projection 85 on the water blocking plate contact surface 57. FIG.

  As shown in FIG. 11, a column body 73 having a C-shaped (substantially the same cross-sectional shape as the lip groove steel) is used, and a top plate 81 is fixed to the upper end side P1 and a bottom plate 79 is separately fixed to the lower end side P2. It is possible to use the water blocking plate support pillar 51 that is configured. Thereby, the surface having the A2 contact flange surface 63 is divided into left and right, and has a slit 82 extending in the vertical direction substantially at the center.

  If the pillar body 73 having a C-shaped cross-sectional shape is used, the water stop plate support pillar 51 can be easily reduced in weight, and the pillar body 73 can be used even if the thickness of the auxiliary tool used is relatively thin. The toe of the foot or the like can be inserted into the slit 82 to strongly press the pressing surface of the assisting tool downward (in other words, the fitting of the assisting instrument can be performed easily and reliably).

  Furthermore, an I-shaped projection 83 extending in the longitudinal direction is disposed substantially at the center of the water blocking plate abutment surface 57 (see FIG. 14A), or a T-shaped projection 85 is disposed (see FIG. 14B). By doing so, the water stop plate 107 can be positioned and installed more reliably and easily, and the part can be used for fixing the water stop plate. That is, if a groove extending substantially vertically to the floor surface 109 is directly formed on the opening edge 111 side, or if a steel material or the like having a U-shaped cross section is disposed, the I-shaped protrusion 83 or the T-shaped protrusion 85 and the water stop plate 107 can be supported from both ends in the frontage direction, and more reliable installation can be performed.

  Next, other assisting devices will be described with reference to FIGS. 12 (a) and 12 (b) and FIGS. 13 (a) and 13 (b). 12 (a) and 12 (b) show the aid 55, and FIG. 12 (a) is a perspective view showing the structure of the aid 55, and FIG. 12 (b) shows the aid 55. It is sectional drawing which shows the state which fitted the water-stop plate support pillar 51 in the fistula 3 using this. 13 (a) and 13 (b) show the aid 255, and FIG. 13 (a) is a perspective view showing the structure of the aid 255, and FIG. 13 (b) shows the aid FIG. 6 is a cross-sectional view showing a state in which a water stop plate support column 51 is fitted into the fistula 3 using a tool 255.

  As shown in FIG. 12 (a), a pressing surface 71 with a large area formed by projecting or bulging forward (building exterior side 105) and / or aft (building interior side 103) from the front and rear surfaces of the auxiliary tool 55 main body In FIG. 12, the pressing surface 71 is formed so as to bulge forward and backward). A pressing force can be applied more reliably. Further, as shown in FIG. 12 (b), the pressing surface 71 does not interfere with the A2 contact wedge surface 63 when it is aligned with the above-described water blocking plate support column 51, and is made to follow the water blocking plate support column 51. Can be fitted into the fistula 3.

  Further, as shown in FIG. 13 (b), an auxiliary tool 255 having a T-shaped projection 272 extending in the longitudinal direction substantially at the center of the B1 contact wedge surface 265 as shown in FIG. 13 (a) is constructed. By fitting the A2 contact wedge surfaces 63 of both the water blocking plate support pillars 51 with the grooves 274, the auxiliary tool 255 can slide vertically along the slits 82, and the water blocking plate support pillars 51 and the auxiliary tool 255 can be integrally formed. Thereby, for example, the loss of the auxiliary tool 255 and the forgetting of fitting of the auxiliary tool 255 can be eliminated, and the installation work of the water blocking plate support pillar 51 can be performed quickly when the water blocking plate 107 is installed.

  As mentioned above, although the typical embodiment of the installation method of the support pillar for water stop boards in this embodiment was explained referring to drawings, the present invention is not limited to these embodiments, and claims Other variations and modifications exist within the scope of the present invention without departing from the spirit and the teaching of the scope of the present invention, all of which are included in the technical scope of the present invention.

  For example, the lid contact surface 39 described above may not be configured, and for example, a lid may be used which is partially supported directly on the bottom surface 43 of the fistula 3 to be fitted. Alternatively, another lid contact surface 239 as shown in FIGS. 15A and 15B may be configured. FIGS. 15A and 15B are views showing the structure of the other lid abutting surface 239, and FIG. 15A is a plan view showing the hole 203 having the lid abutting surface 239. FIG. FIG. 15 (b) is a cross-sectional view showing the arrow B in FIG. 15 (a).

  The lid contact surface 239 is configured by bending and widening the upper end portions of the three surfaces of the two ridge surfaces 209 facing the opening direction of the building opening 101 and the ridge surface 209 facing the building exterior side 105. On the other hand, the ridge 209 facing the building interior side 103 (that is, the ridge formed near the building exterior side 105) is not bent to the floor 109 but is formed substantially vertically to the upper edge of the ridge. Therefore, when the water stop plate support pillar 1 is fitted, no groove is formed in the portion located on the building exterior side 105. That is, when the water stop plate 107 is installed, there is no groove on the floor surface to which the water stop plate 107 contacts, so that the water stop at that portion can be further improved.

  If the fistula 203 having such a lid abutting surface 239 is configured, the floor surface 109 can be maintained flat while the lid 41 is fitted and the fistula 203 is closed, and a water-stopping function can be simply achieved. Can be secured. More specifically, when the two water stop plates 107 are installed in the building opening 101 via the water stop plate support pillars 1, the gap between the two water stop plates 107 is reduced in the above-described embodiment. It is installed so as to cover all the grooves of the portion located on the building exterior side 105 of the lid contact surface 39 by the water blocking packing disposed at the lower end of the water blocking plate 107, and the other lid contact is not secured. In the case of the fistula 203 having the surface 239, since the groove is not formed in the portion located on the outside 105 side of the building as described above, the gap between the two water stop plates 107 must be closely packed and disposed. In addition, since a gap for water to enter is not formed, water stoppage can be ensured while simplifying the arrangement method of the waterstop plate 107.

  The water blocking plate in the present embodiment is an installation structure of the water blocking plate support column which enables the water blocking plate support column to be simply and easily installed while having high pressure resistance and the like.
