Description

  The present invention relates to an installation angle adjustment method for a structure and a spacer for adjusting the installation angle, in which a spacer is arranged at a connection portion of the structure to adjust the installation angle of the structure when the structure is installed. It can be used when attaching handrail support pillars to surfaces with various water gradients such as parapets on the rooftop, waist walls of balconies and verandas, and side walls of outdoor corridors.

  For the purpose of preventing fall and assisting walking, etc. for various structures such as buildings, such as the balconi and veranda walls that extend from the building, the corridors and stairs on the outside, the roof parapets, etc. Handrails are provided. And it is normal that the water gradient is formed in the housing finishing surface where these handrails are provided.

  Accordingly, various methods for adjusting the installation angle have been adopted in the past in installing the handrail support column in correspondence with the water gradient of the finished surface of the housing. For example, a method of attaching a handrail support using a base metal fitting having a structure capable of adjusting the angle is adopted, and the applicant of the present application has also made a proposal regarding this (see Japanese Patent Laid-Open No. 10-331375). ).

  Also, when attaching the handrail struts to the housing finish surface by bolting, a method of adjusting the installation angle of the handrail struts by changing the number of washers stacked on the upstream and downstream sides of the water gradient is also adopted. Yes. Alternatively, flat spacers corresponding to such washers are appropriately procured on-site, and the number of stacked layers is changed to adjust the installation angle of the handrail struts. In addition, these small pieces of spacers procured on-site are used for adjusting the angle by changing the number of stacked layers on the upstream side and downstream side of the water gradient. It is smaller than the size of the cross section, or when the handrail support is attached to the finished surface of the chassis via the foundation bracket, it is smaller than the size of the mounting surface of the foundation bracket to the chassis finished surface. It is.

  Furthermore, the applicant of the present invention can cut the lower end of the handrail strut diagonally by attaching the handrail strut to the housing finish surface using a spacer having an inclined thickness corresponding to the water gradient of the housing finish surface. There has also been a proposal of making it unnecessary (see Japanese Patent Laid-Open No. 10-252237).

  However, the method using the base metal fitting having a structure capable of adjusting the angle described above has the advantage that the angle can be adjusted freely and can be adapted to the situation in the field, but the handrail itself is not suitable. The problem is that the structure is complicated and expensive.

  Moreover, the method of changing the number of stacked layers using the above-described washer or small piece spacer has many problems depending on the field, and the work cannot be standardized, so that the workability cannot be improved. In this method, a washer and the like are laminated and arranged on the upstream side and the downstream side of the water gradient, but nothing is arranged in the middle position so that a cavity is formed, and the appearance is not good as it is. Also, the washer and the like in a stacked state are not preferable in appearance. For this reason, sealing has to be performed so as to cover the periphery of the laminated washers and the like, which is troublesome, and when such sealing is performed, there is a problem that water accumulates inside.

  Furthermore, in the method using a spacer having an inclined thickness corresponding to the water gradient of the cabinet finish surface, the water gradient of the cabinet finish surface at the site is accurate as designed, or the water gradient of the cabinet finish surface is Although installation work can be carried out smoothly if it has been determined by measuring accurately, the water gradient of the finished surface of the building at the site is different from the planned value, or over time If the situation changes due to special circumstances such as subsidence or deformation, there is a problem that it is not possible to deal with them.

  An object of the present invention is to provide a method for adjusting the installation angle of a structure that can freely adjust the installation angle of the structure and improve workability, and a spacer for adjusting the installation angle. is there.

  The present invention intends to achieve the above object by appropriately selecting a spacer for installation angle adjustment to be used from a group of spacers for installation angle adjustment prepared in advance.

  Specifically, in the present invention, when installing a structure, an installation angle adjustment spacer group including a set of a plurality of installation angle adjustment spacers including an installation angle adjustment spacer having at least one kind of inclined thickness is previously set. It is characterized in that the installation angle of the structure is adjusted by selecting and arranging at least one installation angle adjustment spacer from the installation angle adjustment spacer group and arranging it at the connection part of the structure. Is.

  Here, the “installation angle adjustment spacer group consisting of a set of a plurality of installation angle adjustment spacers” prepared in advance includes “at least one type of installation angle adjustment spacers having an inclined thickness”. That's fine.

  Accordingly, one or a plurality of installation angle adjusting spacers having different types of inclined thicknesses may be prepared (preferably, a plurality of units are prepared for each type), or they may have the same type of inclined thickness. Only a plurality of installation angle adjusting spacers may be prepared. In the case of the former, for example, one or a plurality of installation angle adjusting spacers having three kinds of inclination thicknesses of 1 degree, 3 degrees, and 5 degrees of inclination angle of thickness are prepared for each type (preferably, In the latter case, for example, a plurality of installation angle adjusting spacers having an inclination angle of 1 degree may be prepared.

  In addition, the “installation angle adjusting spacer group” may include an installation angle adjusting spacer having a flat plate-like uniform thickness without an inclined thickness. For example, an installation angle adjustment spacer having three types of inclination thicknesses with an inclination angle of 1 degree, 3 degrees, and 5 degrees and an installation angle adjustment spacer having a uniform thickness may be prepared, or A plurality of installation angle adjustment spacers having a thickness inclination angle of 1 degree and an installation angle adjustment spacer having a uniform thickness may be prepared. When the installation angle adjustment spacer group including the installation angle adjustment spacer having the uniform thickness is prepared as described above, not only the installation angle of the structure but also the height and length of the structure can be adjusted simultaneously. This makes it possible to adjust the overall installation posture.

  Furthermore, the installation angle adjustment spacer selected and used from the “installation angle adjustment spacer group” prepared in advance may be “at least one installation angle adjustment spacer”.

  Accordingly, a plurality of installation angle adjusting spacers having different types of inclined thicknesses may be stacked, a plurality of installation angle adjusting spacers having the same type of inclined thickness may be stacked, or a combination thereof. Further, the arrangement may be an arrangement in which an arrangement angle adjusting spacer having a uniform thickness is added to the arrangement. Even if it is the arrangement of only one installation angle adjusting spacer having the above, or the arrangement of only one installation angle adjusting spacer having a uniform thickness, it is included in the present invention.

  Further, the “structure connection portion” where the installation angle adjusting spacer is arranged includes not only the end portion of the structure but also the intermediate portion, and it does not matter whether it is one place or a plurality of places. . The end of the structure refers to a portion where the structure to be installed and the installation object on which the structure is installed are connected, for example, a combination of a handrail support and a frame such as a balconi waist wall. In the case where a place or a pillar of a handrail is attached to the housing via a foundation member, it is a joint location of the foundation member (considered as a part of the structure to be installed) and the housing. The intermediate part of the structure means a part where the respective structural members are connected when the structure to be installed is composed of a plurality of members, for example, a special shape for the purpose of obtaining a design effect. This is a joint portion of a split type handrail post such as a design column or a joint portion between a handrail post and a mounting base member.

  In the present invention, since at least one installation angle adjustment spacer is selected from a group of installation angle adjustment spacers prepared in advance and is arranged at the connecting portion of the structure, the installation angle adjustment used for selection is used. By appropriately changing the spacer, the installation angle of the structure can be freely adjusted.

  For this reason, the installation angle adjustment spacer to be used can be selected and the installation angle of the structure can be adjusted according to the situation of the installation target where the structure is installed. It becomes possible. Therefore, for example, if the water gradient on the finished surface of the building is different from the planned value, or if the situation changes due to special circumstances such as subsidence or deformation over time, It becomes possible to respond. Furthermore, even if it is a retrofit installation in a full sense, such as when it is necessary to install the structure in a place where it was not originally planned, It becomes possible to cope with.

  Compared to the conventional method of adjusting the installation angle of the structure by stacking washers and small spacers in order to cope with the water gradient of the finished surface of the housing, it is easier to standardize the work. In addition to being able to improve the design, it is also easy to design, so there is no need to perform the time-consuming work of sealing the surroundings of washer, etc. Will improve.

  Furthermore, since the installation structure of a structure such as a handrail can be simplified as compared with the case of using the above-described method using the base metal fitting having a structure capable of adjusting the angle, the cost can be reduced.

  Further, the present invention is not only applied to the adjustment of the installation angle of a new structure, but may also be applied to repairing an existing structure. For example, after the structure is installed, the ground sinks, the relative posture and positional relationship between the structure and the installation object on which the structure is installed change, and there is a gap between the structure and the installation object. In such a case, an appropriate installation angle adjusting spacer may be selected according to the angle or width of the gap and disposed in the gap. At this time, if the structure and the installation target are fixed with bolts, screws, etc., the split installation angle can be installed so that the installation angle adjustment spacer can be placed without removing the bolts, etc. It is also effective to prepare an adjustment spacer (a single installation angle adjustment spacer having a predetermined size and shape when combined). The installation angle adjusting spacer of the present invention includes such a split type installation angle adjusting spacer. The said objective is achieved by the above.

  Further, as described above, the installation angle adjustment spacer group prepared in advance only needs to include at least one type of installation angle adjustment spacer having an inclined thickness. If the number of sheets to be arranged is changed, the purpose of freely adjusting the installation angle can be achieved. However, from the viewpoint of further improving workability and further flexibility in angle adjustment, the installation angle adjusting spacer group has at least two types of inclined thicknesses having different thickness inclination angles. It is desirable that an installation angle adjusting spacer is included.

  And, the structures that are subject to installation angle adjustment by the installation angle adjustment method of the present invention described above include parapets on the roof of buildings, waist walls of balconies and verandas, side walls of corridors and stairs provided outdoors in apartment buildings , Side walls of stairs and passages, side walls of pedestrian bridges, waist walls of observation decks for resort areas, partition walls such as flower beds and fountains in parks, animals in zoos, etc. Railing walls that surround the door, the end of the platform of the station, and the pillars of handrails installed on various structures such as the peripheral edge of the deck of the ship. Since these handrail support columns are usually attached to a finished body surface having a water gradient, the present invention can be preferably applied.

  In addition, you may apply this invention other than the installation angle adjustment of the handrail support | pillar. For example, the present invention may be applied by arranging a spacer for adjusting the installation angle between the lower end portion of the support column that supports the outdoor corridor from below and the ground concrete on which the support column is erected. The present invention may be applied by disposing an installation angle adjusting spacer between the lower end of the outer staircase that communicates with the ground concrete. In addition, the present invention may be applied by disposing an installation angle adjusting spacer between the lower end portion of the support column that supports the balconi placed on the upper side of the gradient roof from below and the inclined roof surface of the gradient roof.

  Furthermore, as the installation angle adjusting spacer used for realizing the installation angle adjusting method of the structure of the present invention described above, the following installation angle adjusting spacer of the present invention can be mentioned. That is, the present invention is a structure installation angle adjusting spacer that is arranged at a connecting portion of a structure and used for adjusting the installation angle of the structure when the structure is installed, and a plurality of prepared spacers The installation angle that constitutes one element of the installation angle adjustment spacer group consisting of a set of installation angle adjustment spacers, has inclined thicknesses with different thicknesses at both end portions, and is overlaid. It has an engaging part engaged with the spacer for other installation angle adjustment which comprises the spacer group for adjustment.

  Here, the spacer for adjusting the installation angle can be made of any material such as synthetic resin, metal, ceramic, wooden, etc. The magnitude of the load received from the structure to be installed, the type of structure to be installed, and the installation location It may be selected appropriately according to the situation, the purpose of installation, etc. For example, when strength and weather resistance are required to some extent, a hard synthetic resin such as ABS (polymer alloy in which polybutadiene rubber particles are uniformly dispersed in a styrene acrylonitrile copolymer) can be suitably used.

  In this way, if the installation angle adjusting spacer having the inclined thickness is provided with an engaging portion so that it can be engaged with other installation angle adjusting spacers, the arrangement of the installation angle adjusting spacers can be easily and smoothly arranged. It is possible to improve the workability.

  Moreover, in the installation angle adjusting spacer described above, it is desirable that the engaging portion is freely engageable with each of all the other installation angle adjusting spacers constituting the installation angle adjusting spacer group. In other words, it is desirable to provide a common engaging portion for all of the plurality of installation angle adjustment spacers constituting the installation angle adjustment spacer group.

  When such a common engagement portion is provided, it is possible to combine any installation angle adjustment spacers in the prepared installation angle adjustment spacer group, and to combine them in any order. Since it is possible to superimpose, the flexibility of adjusting the installation angle is further improved, and the workability is also improved.

  Further, in the installation angle adjusting spacer described above, it is desirable that the engaging portion is disposed so as to prevent all relative planar movements of the engaged body in a plane parallel to the front and back surfaces.

  Here, the “engaged body” refers to an object to be engaged with, and when another installation angle adjusting spacer is the other party, a structure to be installed (for example, a handrail column or its attachment) This includes both cases where the base member for use as a counterpart is a counterpart to which an object to be installed (for example, a waist wall of a balconi) is the counterpart.

  In addition, “prevent all relative planar movement” means to prevent translational movement in the direction along the front and back surfaces (two-dimensional displacement that is performed on the plane while maintaining a certain posture without rotating) It also means that the rotational movement around the normal direction of the front and back surfaces is prevented.

  A typical example of the engaging portion that prevents such a two-dimensional displacement from the engaged body is one that engages the groove portion and the protruding portion arranged in a cross shape (see FIG. 3 and later). However, the present invention is not limited to this. For example, a groove portion and a protruding portion arranged in a Y shape may be engaged, or concave portions and convex portions appropriately distributed on the front and back surfaces may be used. What engages a part etc. may be sufficient.

  When an engagement portion that prevents such a two-dimensional deviation from the engaged body is provided, the placement work of the installation angle adjustment spacers can be facilitated, and workability can be improved. The stability at the time of tightening the bolt when the structure is finally fixed and the stability of the structure after installation are further improved.

  The installation angle adjusting spacer described above preferably has approximately the same size and shape as the size and shape of the coupling surface of the connecting portion of the structure.

  Here, when the connecting part of the structure is the end of the structure, the “joining surface of the connecting part of the structure” refers to the end face of the structure, that is, the mounting surface to the installation object. In the case where the lower end surface of the handrail support column or the handrail support column is attached to the housing via the foundation member, the attachment surface of the foundation member to the housing is provided. Moreover, when the connection part of a structure is an intermediate part of a structure, the connection surface of each structural member which comprises a structure is said.

  Further, the shape of the coupling surface, and hence the outer peripheral shape of the spacer for adjusting the installation angle, is arbitrary such as a rectangle, a square, a triangle, a circle, an ellipse, and the like.

  In this way, when the installation angle adjusting spacer has substantially the same size and shape as the size and shape of the coupling surface of the connecting portion of the structure, when the installation angle adjusting spacer is disposed, The outer peripheral side surface and the outer peripheral side surface of the installation angle adjusting spacer are substantially flush, and the appearance is further improved. In this sense, the present invention is preferably applied to a structure whose cross section is not so large, that is, a columnar or bar-shaped structure. This is because it is easy to prepare installation angle adjusting spacers having substantially the same size and shape.

  Furthermore, the installation angle adjusting spacer described above has a through-hole penetrating the front and back, and the engaging portion is formed on one surface of the front and back, a groove portion extending from the through hole to the outer peripheral side surface, and the other surface of the front and back It is desirable that the projection portion is formed to be engaged with a groove portion having the same shape as the groove portion.

  Thus, when it is set as the engaging part provided with the groove part which extends from the through hole to the outer peripheral side surface, rainwater that has entered the structure can be extracted from the through hole to the outside through the groove part. In addition, in order to make the groove part function as drainage, it is necessary to be continuously formed from the through hole to the outer peripheral side surface, but the protrusion part only needs to be able to engage with the groove part of the other spacer for adjusting the installation angle. It is not necessary to be continuously formed in a jetty shape from the through hole to the outer peripheral side surface, and may be formed intermittently.

  As described above, according to the present invention, since at least one installation angle adjustment spacer is selected from a group of installation angle adjustment spacers prepared in advance and arranged at the connection portion of the structure, the structure is The installation angle of the structure can be adjusted freely by appropriately changing the installation angle adjustment spacer to be selected and used according to the situation of the object to be installed. Since laborious work can be omitted, there is an effect that workability can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a vertical cross-sectional view of a handrail 10 according to this embodiment installed by applying the installation angle adjusting method for a structure of the present invention. FIG. 2 is an enlarged view of the mounting structure of the handrail 10, and FIGS. 3 and 4 are perspective views of the installation angle adjusting spacer 20 used when the handrail 10 is installed. Yes.

  In FIG. 1, a handrail 10, which is a structure, is installed in a building housing 1 such as a veranda or a balcony waist wall that is an installation target. The handrail 10 is disposed along the upper end of the jetty-shaped building housing 1 and has a handrail headboard 11 having a substantially elliptical cross section, and the handrail headboard 11 is disposed between the handrail headboard 11 and the building housing 1. 11 is provided with a hollow prismatic column 12 supporting 11 and a base member 13 for attaching the column 12 to the building frame 1. The handrail cap 11 and the support column 12 are, for example, extruded products made of aluminum alloy, and the base member 13 is, for example, a metal fitting made of aluminum or stainless steel. In this embodiment, for convenience of explanation, the base member 13 is also regarded as a part of the structure to be installed.

  In FIG. 2, the building finishing surface 2 at the upper end of the building housing 1 has a water gradient inclined by α degrees with respect to the horizontal plane. Usually, the upper end surfaces of the veranda and the waist wall of the balconi often have a water gradient flowing from the outdoor side toward the indoor side.

  An anchor member 3 is embedded in the building housing 1 made of concrete or the like in advance. The lower end portion 12A of the support column 12 is fitted and fixed to the base member 13, and the base member 13 holds the four screws 4 as anchor members with the two installation angle adjusting spacers 20 sandwiched therebetween. 3 is screwed into the building housing 1 and fixed to the building housing 1, whereby the column 12 is erected on the building housing 1.

  3 is a perspective view of the installation angle adjusting spacer 20 as viewed from the upper surface 21 side, and FIG. 4 is a view of FIG. 3 turned upside down, that is, the installation angle adjusting spacer 20 as viewed from the lower surface 22 side. FIG. The installation angle adjusting spacer 20 is made of, for example, a hard synthetic resin such as ABS (polymer alloy in which polybutadiene rubber particles are uniformly dispersed in a styrene acrylonitrile copolymer).

  3 and 4, the installation angle adjusting spacer 20 has a substantially rectangular shape on the front and back surfaces, and a thickness dimension T1 at one end and a thickness dimension T2 at the other end. It has a different slope thickness. As the thickness inclination angle β, it is preferable to prepare a plurality of types having different angles. For example, here, installation angle adjustment spacers 20 having three types of inclined thicknesses of β = 1 degree, 3 degrees, and 5 degrees are prepared, and the installation angle adjustment spacer group is configured. Further, an installation angle adjusting spacer 20 having a flat plate-like thickness such that β = 0 degrees, that is, T1 = T2 may be prepared.

  In the center of the installation angle adjusting spacer 20, a circular through hole 23 penetrating the front and back is provided. Further, four protrusions 25 that are continuously formed from the through hole 23 to the outer peripheral side surface 24 are provided on the upper surface 21 of the installation angle adjusting spacer 20. These protrusions 25 are arranged radially at intervals of 90 degrees around the through hole 23, that is, in a cross shape when viewed as a whole. On the other hand, on the lower surface 22 of the installation angle adjusting spacer 20, four groove portions 26 continuously formed from the through hole 23 to the outer peripheral side surface 24 are provided. These groove portions 26 are also arranged radially at intervals of 90 degrees around the through hole 23, that is, in a cross shape when viewed as a whole.

  The four protruding portions 25 and the groove portions 26 that are respectively provided in four are arranged at the same position on the front and back of the installation angle adjusting spacer 20, and the sectional shape and size of the protruding portion 25 and the sectional shape and size of the groove portion 26 are the same. Are almost identical. Further, all the installation angle adjusting spacers 20 to be prepared are provided with the same projecting portion 25 and groove portion 26 for common use. Accordingly, when the two spacers 20 are overlapped so that the upper surface 21 of one installation angle adjusting spacer 20 and the lower surface 22 of another installation angle adjusting spacer 20 are in contact with each other, the upper surface 21 of one spacer 20 protrudes. The portion 25 and the groove portion 26 on the lower surface 22 of the other spacer 20 are engaged with each other so that the relative positional relationship between them is determined. For this reason, both the protrusion part 25 and the groove part 26 function as an engaging part engaged with the spacer 20 for other installation angle adjustment.

  Further, as shown in FIG. 2, the lower surface 13 </ b> A of the base member 13 is also provided with a groove portion 13 </ b> B similar to the groove portion 26 of the lower surface 22 of the installation angle adjusting spacer 20, and the upper surface 21 of the installation angle adjusting spacer 20 protrudes. It can be engaged with the portion 25. Therefore, in the present embodiment, the engaged members that are the counterparts of the engagement of the installation angle adjusting spacer 20 include not only the other installation angle adjusting spacer 20 but also the base member 13.

  The lower surface 13A of the base member 13 corresponds to the coupling surface of the connection portion of the handrail 10 that is a structure to be installed. The size and shape of the lower surface 13A and the upper surface 21 of the installation angle adjusting spacer 20 The size and shape of the lower surface 22 are substantially the same. However, since the chamfer 13C is provided around the lower surface 13A of the base member 13, the installation angle adjusting spacer 20 is smaller by the dimension of the chamfer 13C.

  As shown in FIGS. 3 and 4, in the vicinity of the four corners of the installation angle adjusting spacer 20, screw through holes 27 for passing the screws 4 are provided through the front and back.

  In this embodiment, the installation angle of the column 12 of the handrail 10 is adjusted using the installation angle adjustment spacer group including the plurality of installation angle adjustment spacers 20 as follows.

  First, one or a plurality of installation angle adjustment spacers 20 to be used are selected from the set of installation angle adjustment spacer groups according to the inclination angle α (see FIG. 2) of the building finishing surface 2 of the building enclosure 1. Select. At this time, the total angle of the inclination angles β (see FIG. 3) of the thicknesses of the selected installation angle adjusting spacers 20 is made to coincide with the inclination angle α of the housing finished surface 2.

  For example, when the inclination angle of the housing finishing surface 2 is α = 1 degree, only one installation angle adjusting spacer 20 having an inclination thickness of β = 1 degree is selected. When α = 2 degrees, only two spacers 20 having β = 1 degree are selected. When α = 3 degrees, it is preferable to select only one spacer 20 with β = 3 degrees, but only three spacers 20 with β = 1 degree may be selected. Further, when α = 4 degrees, it is preferable to select one spacer 20 with β = 1 degree and one spacer 20 with β = 3 degrees, but only the spacer 20 with β = 1 degree is selected. You may select four. When α = 5 degrees, it is preferable to select only one spacer 20 with β = 5 degrees. However, one spacer 20 with β = 3 degrees and two spacers 20 with β = 1 degree are selected. May be selected, or only five spacers 20 with β = 1 degree may be selected. Further, when α = 6 degrees, it is preferable to select only two spacers 20 with β = 3 degrees, or select one spacer 20 with β = 5 degrees and β = 1 degree. However, one spacer 20 with β = 3 degrees and three spacers 20 with β = 1 degree may be selected, or only six spacers 20 with β = 1 degree may be selected. . The same applies to the case where the inclination angle α of the housing finished surface 2 is 7 degrees or more.

  Next, the selected installation angle adjusting spacer 20 is disposed at a predetermined connecting portion on the housing finishing surface 2. At this time, if there are a plurality of selected spacers 20, the protrusions 25 and the groove portions 26 of the spacers 20 are overlapped and arranged.

  Further, when it is desired to simultaneously adjust the height of the column 12 of the handrail 10, if an installation angle adjusting spacer 20 having a uniform thickness (β = 0 degree) is prepared, it may be used. Alternatively, as shown in FIG. 5, two installation angle adjusting spacers 20 having the same thickness inclination angle β may be arranged in opposite directions so that the two pieces have the same thickness.

  And, on the installation angle adjusting spacer 20 in which the base member 13 is arranged on the housing finishing surface 2 (in the case where a plurality of spacers 20 are arranged in an overlapping manner, on the spacer 20 arranged on the uppermost side) The base member 13 and one or a plurality of spacers 20 are simultaneously gathered and fixed to the building frame 1 by four screws 4 (see FIG. 2).

  Thereafter, the support column 12 is fixed to the base member 13, and the handrail headboard 11 is attached to the support column 12 to complete the installation of the handrail 10. Thereby, the support | pillar 12 makes an angle with respect to the housing finishing surface 2, and is fixed, As a result, the support | pillar 12 will be in the state standing upright with respect to the horizontal surface.

  According to this embodiment, there are the following effects. That is, since at least one installation angle adjustment spacer 20 is selected from the group of installation angle adjustment spacers prepared in advance, the column 12 of the handrail 10 can be changed by appropriately changing the spacer 20 to be used. Can be freely adjusted (in this embodiment, adjusted in units of 1 degree). For this reason, since the installation angle adjustment spacer 20 to be used can be selected and the installation angle of the column 12 can be adjusted according to the situation of the building finishing surface 2 of the building frame 1 where the handrail 10 is installed, the installation angle of the support column 12 can be adjusted. It is possible to respond to the field.

  Therefore, for example, even if the water gradient of the finished body surface 2 is different from the planned value, or the situation changes due to special circumstances such as subsidence or deformation over time, it will be possible can do. Furthermore, even if the handrail 10 is installed later in a place where the handrail 10 is not initially planned, it can be easily handled.

  Also, since it is easier to standardize the work than the conventional method of adjusting the installation angle of the support column 12 by laminating washers and small piece spacers in order to cope with the water gradient of the finished body surface 2 as in the past, In addition to being able to improve performance, it is possible to omit the time-consuming work of sealing the surroundings of washers, etc., which has been done in the past. Can be improved. The installation angle adjusting spacer 20 is smaller than the lower surface 13A of the base member 13 by the dimension of the chamfer 13C provided around the lower surface 13A of the base member 13 (see FIG. 2). Sealing may be performed around the spacer 20 so as to correspond to the dimension.

  Further, since the base member 13 having a simple structure can be used as compared with the case of using the above-described method using the base metal fitting having a structure capable of adjusting the angle, the cost can be reduced.

  And since the installation angle adjusting spacer 20 is attached and fixed to the building housing 1 by the screws 4 together with the base member 13, the construction time can be shortened.

  In addition, the installation angle adjustment spacer group prepared in the present embodiment includes installation angle adjustment spacers 20 having three types of inclination thicknesses in which the inclination angle of the thickness is β = 1 degree, 3 degrees, and 5 degrees. Therefore, compared with the case where only the installation angle adjustment spacer having one kind of inclined thickness is prepared and the installation angle is adjusted by the number of stacked layers, the workability can be further improved and the angle can be further adjusted. Freedom can be achieved.

  Since the installation angle adjusting spacer 20 is provided with the projecting portion 25 and the groove portion 26 that function as the engaging portion, the spacers 20 can be easily and smoothly arranged and the workability can be improved. Can be achieved.

  Further, the protruding portion 25 and the groove portion 26 are shared by all of the plurality of installation angle adjusting spacers 20 constituting the installation angle adjusting spacer group. For this reason, it is possible to combine arbitrary spacers 20 in the installation angle adjustment spacer group prepared in advance and to superimpose them in an arbitrary order, thereby further improving the flexibility of installation angle adjustment. In addition, the workability can be improved.

  Further, since the projecting portion 25 and the groove portion 26 are arranged in a cross shape, two-dimensional displacement and rotation with the engaged body (another installation angle adjusting spacer 20 or the base member 13) that is the counterpart of the engagement. Therefore, it is possible to more easily arrange the installation angle adjusting spacers 20 so that the workability can be further improved, and the support column 12 and the base member 13 are fixed. The stability of the screw 4 during screwing and the stability of the handrail 10 after installation can be further improved.

  And since the installation angle adjusting spacer 20 has substantially the same size and shape as the size and shape of the lower surface 13A of the foundation member 13, when the spacer 20 is arranged, the outer peripheral side surface of the foundation member 13 and Since the outer peripheral side surface of the spacer 20 is substantially flush, the appearance can be further improved.

  Furthermore, since the installation angle adjusting spacer 20 has a through hole 23 and the groove portion 26 is formed so as to reach the outer peripheral side surface 24 from the through hole 23, the spacer is accumulated inside the support column 12 and the foundation member 13. Rainwater can be drained to the outside through the through hole 23 and the groove 26. When a plurality of installation angle adjusting spacers 20 are arranged in an overlapping manner, the groove portion 26 of the spacer 20 arranged on the lowermost side functions as a water drainage path, and the groove portions 26 of the other spacers 20 are connected to each other. It will function as a joint.

  That is, in the above-described embodiment, the installation angle adjusting spacer 20 has a substantially rectangular shape, but the installation angle adjusting spacer of the present invention is not limited to such a shape, and is circular or elliptical. For example, as shown in FIG. 6, if the structure to be installed is a column having a circular cross section, a circular installation angle adjusting spacer 40 corresponding to the shape, square, triangle, hexagon, etc. It is good.

  Moreover, in the said embodiment, although the protrusion part 25 and the groove part 26 which function as an engaging part were arrange | positioned in the cross shape, it is not limited to such arrangement | positioning, For example, as shown in FIG. The engaging portions 42 may be radially arranged in three directions around the through hole 41. Even with the engagement portion 42 having such a substantially Y-shaped arrangement, two-dimensional displacement and rotation with the engaged body that is the counterpart of the engagement can be prevented.

  Furthermore, in the said embodiment, the location which couple | bonds the lower surface 13A of the base member 13 and the building finishing surface 2 of the building housing 1 is a location where the installation angle adjusting spacer 20 should be arranged, that is, “the structure of the structure” However, the “connecting part of the structure” is not limited to the end part of the structure, and may be an intermediate part.

  Therefore, for example, a spacer for adjusting the installation angle may be arranged at a position where the lower end portion 12A of the support column 12 and the base member 13 are joined. Alternatively, as shown in FIG. A design column 51 may be configured to interpose an installation angle adjusting spacer 50 at a location to provide a design effect.

  And in the said embodiment, although this invention was applied to the installation angle adjustment of the support | pillar 12 of the handrail 10, the structure used as the installation angle adjustment object by the installation angle adjustment method of this invention is a support | pillar of the handrail 10. It is not limited to 12. For example, as shown in FIG. 8, an installation angle adjusting spacer 64 is provided between the lower end portion of the support pillar 62 that supports the outdoor corridor 61 of the apartment house 60 from below and the ground concrete 63 that erects the support pillar 62. The present invention may be applied by arranging it, and an installation angle adjusting spacer 66 may be disposed between the lower end of the outer stairway 65 that connects the outdoor corridor 61 and the ground and the ground concrete 63. May be.

  Further, as shown in FIG. 9, the installation angle is adjusted between the lower end portion of the support column 72 that supports the balconi 71 placed on the upper side of the sloped roof 70 of the lower house from the lower side and the sloped roof surface 73 of the sloped roof 70. The present invention may be applied by arranging the spacer 74. In this case, the installation angle adjusting spacer 74 may not be fixed to the sloped roof 70 side, but only to the support column 72 side.

  The present invention relates to an installation angle adjustment method for a structure and a spacer for adjusting the installation angle, in which a spacer is arranged at a connection portion of the structure to adjust the installation angle of the structure when the structure is installed. It can be used when attaching handrail support pillars to surfaces with various water gradients such as parapets on the rooftop, waist walls of balconies and verandas, and side walls of outdoor corridors.
