  The above-mentioned temporary handrails are not basically problematic in that it is possible to provide temporary handrails on the wall of the building formed on the roof of the building, but there are minor problems when using them. May be pointed out.

  That is, in the above-mentioned temporary handrail, since the socket on which the column on which the handrail bar is provided is mounted is positioned on the outer side of the wall, when the column is mounted on the socket, the handrail is attached to the column mounted on the socket. When the bar is provided, it is necessary to prevent the column and the handrail bar from falling from the viewpoint of security.

  For this reason, it is essential to eliminate the risk of falling by connecting a pulling member such as a rope to the support column and handrail bar when attaching the support column to the socket and installing a handrail bar on the support column. Impairs workability when installing or removing.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a temporary handrail that improves workability when the temporary handrail is provided or removed.

In order to achieve the above-described object, a solution means of the present invention is a temporary handrail comprising a plurality of assembly columns that are detachably provided on the wall and handrails that are detachably mounted on the assembly columns. The assembly column is detachably provided on the upper end of the ridge wall so as to be bridged from the inside of the ridge wall to the outside of the ridge wall, and the beam member is movable along the beam material. A locking portion provided, a guide portion provided continuously to the beam material, a support column that is supported by the guide unit so as to be movable up and down and adjusts the height position according to the height of the wall, and the support column. The guide part is connected to a base end positioned on the inner side of the rib wall of the beam member, and is opposed to the locking part and between the locking part and the locking part. has a fixing means for clamping the buttresses, further, the guide portion having a cross-sectional angle U-shaped groove In addition, a pin hole is provided at the center in the axial direction, and the column is inserted into the groove so as to be movable up and down, and the column has a plurality of pin holes spaced along the axial direction. The height position of the support column is adjusted by inserting a pin into any one of the pin holes and the pin hole on the guide portion side .

  Therefore, in the present invention, the locking portion provided on the beam material spanning the upper end portion of the wall and the fixing provided on the guide portion at the base end of the beam material so as to face the locking portion. By sandwiching the eaves wall with the means, it is possible to provide the assembly strut on the eaves wall, and to position the guide portion inside the eaves wall where the base end of the beam material is positioned.

  Since the fixing means is provided in the guide portion positioned inside the wall, the operator can practice the operation with respect to the fixing means on the roof floor inside the wall. It can be implemented.

  And since the guide part is positioned inside the fence wall, the column held by the guide part is positioned inside the fence wall. By connecting the handrail to the pillar, the temporary handrail is broken. It can be provided inside the wall.

  Since the column is positioned inside the fence wall, the column is positioned outside the fence wall, and therefore, for safety reasons, a pulling member such as a rope is attached to the railing to prevent the handrails installed on the pillar from falling. Compared with the case where the operation | work which connects is required, the operation | work which connects pulling members, such as a rope, with a handrail is unnecessary.

  Incidentally, in the present invention, by providing the assembly struts on the eaves wall, the guide portion positioned inside the eaves wall holds the struts in advance, so that the operation of holding the support posts in the guide portion is not required.

  Further, in the present invention, since the locking portion is movable along the beam material, the locking portion can be locked even when the thickness dimension of the wall between the fixing means varies. This can be dealt with by selecting the fixing position of the part to the beam material.

  And, when the fixing position of the locking portion with respect to the beam material is, for example, a position closer to the center portion of the beam material, the so-called surplus portion that is so-called ahead of the locking portion protrudes out of the wall. It will not be an obstacle inside.

  Furthermore, in the present invention, since the support column is held by the guide portion so as to be movable up and down, the height of the support column is determined according to the height position of the guide portion, that is, according to the height position of the upper end of the wall. It becomes possible to raise and lower the position, and it becomes possible to provide handrails of a preferred height on the wall with different upper end heights.

According to the present invention, the following effects can be achieved.
It is possible to improve the workability when the temporary handrail is provided or removed.
In addition, in this invention, since the handrail is provided on the support column held by the guide portion that is positioned on the inner side of the wall, the handrail is positioned on the inner side of the wall. Compared to the case where it is connected to the column provided outside the fence wall and positioned on the outside of the fence wall, it is possible to completely eliminate the room for a person to enter the upper end of the fence wall, and security by providing a handrail It becomes possible to improve.
Further, in the present invention, since the locking portion is movable along the beam material, the locking portion can be locked even when the thickness dimension of the wall between the fixing means varies. This can be dealt with by selecting the fixing position of the part to the beam material.
Further, according to the present invention, a handrail is installed on the column, and the column is held by the guide portion so as to be movable up and down, and the height position is adjusted according to the height of the wall, so that the height of the upper end is different. It becomes possible to provide a handrail with a preferred height on the wall.

It is a fragmentary top view which shows the state by which the temporary handrail of this invention was provided in the entrance corner part. It is a partial elevation view of the temporary handrail shown in FIG.

  Hereinafter, the present invention will be described based on the illustrated embodiment. The temporary handrail according to the present invention projects upward from, for example, a roof F of a concrete building (not illustrated) as illustrated. It is suitable for being provided on the wall W formed as described above.

  As shown in FIGS. 1 and 4, the ridge wall W is formed so as to have an umbrella (not shown) at the upper end (not shown), and as shown in FIG. It may be formed to stand up to a single-wall state without having, and furthermore, as shown in FIG. 6, it may stand up to a single-wall state, but may be formed as low as a so-called car stop, In any one of these ridge walls W, the temporary handrail of the present invention can be realized.

  4 is substantially the same as the height position of the upper end of the wall W in FIG. 4, but in the left-right direction in FIG. 1 at the wall W in FIG. 1. Assuming that the thickness dimension at the upper end is a standard, it is assumed that the thickness dimension at the upper end of the wall W in FIG.

  Although not shown in each figure, for example, the rooftop floor F is formed in a waterproof structure having asphalt roofing or the like, and the inner wall of the wall W is a finish that is continuous with the waterproof structure of the rooftop floor F, Further, the outer wall of the wall W is generally provided with a waterproof measure such as a tile.

  Incidentally, when referring to the thickness dimension of the eaves wall W, the left-right direction in FIG. 1 is indicated as the thickness direction, and it is common when referring to the thickness dimension of the eaves wall W in each of the following embodiments.

  On the other hand, as shown in FIGS. 1, 2, and 3, the temporary handrail is detachably installed between a plurality of assembly columns P that are detachably provided at the upper end of the wall W and the assembly columns P. And a handrail H.

  The assembly column P includes a beam member 1 (see FIGS. 1 and 3), a locking portion 2 (see FIGS. 1 and 3), a guide unit 3, and a column 4; A stop portion 2 is provided movably along the beam member 1, and a guide portion 3 is connected to a base end positioned on the inner side of the wall W of the beam member 1 and is opposed to the locking portion 2. The fixing means 5 (refer FIG. 1) which clamps the collar wall W between the latching | locking parts 2 is comprised.

  To explain sequentially, the beam member 1 is in the left-right direction in FIG. 1, and the axial direction that is the vertical direction in FIG. 3 crosses the axial direction of the wall W that is the horizontal direction in FIGS. 2 and 3. Thus, it is detachably provided at the upper end portion of the eaves wall W so as to span from the inner side of the eaves wall W to the outside of the eaves wall W (see FIG. 1).

  Therefore, the length of the beam member 1 in the axial direction is such that the thickness of the upper end portion of the eaves wall W is equal to the thickness of the upper end portion of the so-called standard type eaves wall W shown in FIG. Even when the length is approximately 1.5 times the length, it is assumed that the beam member 1 can be bridged, that is, has a length that allows the temporary handrail of the present invention to be used.

  On the other hand, the beam member 1 is made of a square pipe made of hard, for example, iron, aluminum alloy, or hard synthetic resin, so that when it is placed on the upper end of the wall W, it can stand still without rolling. When it has the latching | locking part 2, it considers that this latching | locking part 2 does not rotate centering on the beam material 1, ie, does not shake.

  Considering that the beam material 1 does not roll at the upper end of the ridge wall W, and considering the prevention of swinging of the locking portion 2 provided on the beam material 1, the beam material 1 is attached to the ridge wall W. The work spanning the upper end can be quickly practiced.

  Incidentally, in the illustrated case, when the beam member 1 is bridged over the upper end portion of the wall W and fixedly fixed, the lower surface does not come into contact with the upper end of the wall W and the upper end of the wall W is not touched. It is said that the beam material 1 is used, that is, the temporary handrail is provided on the ridge wall W, so that it is avoided in advance that the ridge wall W is not damaged. Of course, the buffer material C (see FIG. 3) may be provided between the lower surface of the beam member 1 and the upper end of the eaves wall W so that the lower surface of the beam member 1 contacts the upper end of the eaves wall W. It is.

  Returning, as shown in FIG. 7, the beam member 1 has a plurality of pin holes 1 a penetrating horizontally on both side surfaces in the axial direction so as to cross the axial direction at appropriate intervals along the axial direction. It is said. Further, the beam member 1 is screwed with a bolt 11 outside the wall W which is the right end portion in FIG. 7, that is, a tip portion (not shown) protruding outdoors, and the bolt 11 is engaged with the locking portion. 2 is set as a stopper.

  The locking part 2 is movably provided on the beam member 1, and thereby, the position provided on the beam member 1 of the locking part 2 according to the thickness dimension of the upper end of the wall W, that is, fixedly The position to be fixed can be selected. And the latching | locking part 2 is movably hold | maintained at the beam material 1 so that it can move with respect to the beam material 1, and the receiving part which is integrally connected to this slider 21, and hangs down. 22.

  The slider 21 is a square pipe made of iron, aluminum alloy, or hard synthetic resin, like the beam member 1, and has a cross-sectional shape similar to the cross-sectional shape of the beam member 1, and is in the left-right direction in FIG. 7. The axial direction coincides with the axial direction of the beam member 1 and is held movably without rolling with respect to the beam member 1.

  Then, as shown in FIG. 7, the slider 21 has a plurality of pin holes 21 a penetrating horizontally on both side surfaces in the axial direction so as to cross the axial direction at appropriate intervals along the axial direction. The pin hole 21a is aimed at the pin hole 1a formed in the beam member 1 described above.

  Therefore, when the pin 23 inserted through the pin hole 21a of the slider 21 passes through the pin hole 1a of the beam member 1, the slider 21 is prevented from moving relative to the beam member 1, and the slider 21, that is, the locking portion 2 is moved. It is in a state of being fixedly fixed to the beam material 1.

  Incidentally, although the number of pin holes 21a of the slider 21 is two in the drawing, the number of pin holes 21a may be three or more. Although the interval is narrower than the mutual interval in the plurality of pin holes 1a formed in the beam member 1, it may be widened instead of this, although not shown. And although the pin 23 which penetrates the pin hole 21a of the slider 21 is not shown in figure, for example, it is preferable that the above-mentioned beam material 1 is connected and held to the bolt 11 screwed by using a wire or the like.

  7 shows a state in which the cushioning material C is provided on the lower surface of the slider 21, the cushioning material C is shown in FIG. 7 so that it can be easily understood that the cushioning material C is made of a rubber material. Is intentionally displayed in cross section. 7 shows the pin 23 in the locking portion 2. In FIG. 1, FIG. 4, FIG. 5, and FIG. 6, the pin 23 is shown in order to avoid complication of each figure. The inserted portion is blacked out and the pin 23 is not shown.

  On the other hand, the receiving portion 22 is made of the same material as the slider 21, and as shown in FIG. 7, the vertical axis direction in FIG. 7 is orthogonal to the axial direction of the slider 21, and in FIG. 7. A base end portion (not shown) as an upper end portion is connected to the slider 21 by welding, and a tip portion (not shown) as a lower end portion in FIG. The contact portion 24 is integrally formed, and the contact portion 24 is in contact with the outer surface of the wall W from the outdoor side (see FIG. 1).

  Incidentally, although the receiving portion 22 is connected to the tip end portion (not shown) which is the right end portion in FIG. 7 of the slider 21 in the drawing, the slider 21 is not shown but is replaced by the slider 21. It is good also as connecting with the central part of the axial direction of these.

  Therefore, in the locking portion 2 formed as described above, when the pin hole 21a of the slider 21 is aimed at the pin hole 1a of the beam member 1, the pin 23 is inserted into the pin holes 21a and 1a. Is fixedly fixed to the beam member 1 at a so-called selected position.

  In addition, since the contact part 24 provided in the front-end | tip part of the receiving part 22 consists of a rubber material in illustration, in order to understand this easily, in FIG. The cross section is shown.

  The guide portion 3 is made of the same material as the beam material 1 and has a square U-shaped cross-sectional shape, and an inner groove (not shown) is a roof floor on the inner side of the wall W as shown in FIG. The base end which becomes the left end in FIG. 1 of the beam material 1 is welded to the back surface of the central portion in the axial direction which is the vertical direction in FIG. 1 so as to face the F side (see FIG. 8).

  And as shown in FIG. 8, the guide part 3 has a pin hole 3a penetrating horizontally in a direction crossing the axial direction on both side surfaces of the central part in the axial direction. It is assumed that the pin 31 is inserted. In FIG. 8, the pins 31 in the guide unit 3 are displayed. In FIGS. 1, 4, 5, and 6, the pins 31 are displayed to avoid complications. Is omitted.

  Therefore, in the guide portion 3, since the inner groove faces the rooftop floor F that is the inside of the wall W, the pin 31 is in a state where the operator is on the rooftop F that is the inside of the wall W. The operation of changing the height position of the column 4 with respect to the guide unit 3 or the operation of holding the column 4 of different length in the guide unit 3 instead of the column 4 held in advance. Makes it possible to do.

  By the way, the column 4 has a total length of about 93 centimeters, for example, and when the column 4 stands up on the rooftop floor F, the handrail H installed on the column 4 has a so-called optimum height position. (See FIGS. 1 and 6).

  The column 4 is made of a round pipe made of the same material as that of the guide portion 3 in the drawing, and is horizontally opened in a direction crossing the axial direction on both side surfaces along the axial direction which is the vertical direction in FIG. A plurality of pin holes 4a that are bored and are aimed at the pin holes 3a formed in the guide portion 3 are provided at appropriate intervals in the axial direction.

  Moreover, the support | pillar 4 is made to weld the gravity pin 41 to the so-called front surface used as the left side surface in FIG. 8, ie, the front surface facing the rooftop floor F side which is the inner side of the wall W, and this gravity pin 41 is In FIG. 8, the axial direction which is the left-right direction is orthogonal to the axial direction of the support column 4, and the tip is directed to the roof floor F side inside the wall W.

  In addition, the gravity pin 41 is provided near the center in the axial direction of the support column 4 and also at the upper end of the support column 4 as shown in FIG. All handrails H can be installed.

  Since the support column 4 has the gravity pin 41 and the support column 4 can be moved up and down with respect to the guide unit 3, the guide unit 3 has a cross section of a corner U so that the gravity pin 41 does not interfere with the guide unit 3. It is assumed that the inside is opposed to the rooftop floor F side, which is the inside of the wall W, with a letter shape.

  Incidentally, although the support column 4 is made of a round pipe in the drawing, it may be made of a square pipe, although not shown, from the viewpoint that it can move up and down with respect to the guide portion 3. When the material is the same and the length and wall thickness are the same, the weight of the member is reduced when the support column 4 is made of a round pipe, compared to the case where the support column 4 is made of a square pipe. It becomes advantageous from.

  In addition, as is well known, the gravity pin 41 has a stopper 41a (see FIG. 8) that can be moved into and out of the so-called main body. When the main body is inserted through a so-called hole, the stopper 41a is When the main body moves in a predetermined stroke, the stopper 41a jumps out of the main body and is prevented from coming out of the hole even if the main body moves in the reverse direction. In FIG. 2, the illustration of the gravity pin 41 is omitted.

  On the other hand, the fixing means 5 that the guide portion 3 has at the lower end portion (not shown) in FIG. 8 includes a socket 51 that is held by the guide portion 3 and a bolt that is screwed into the socket 51. 52.

  In this fixing means 5, the socket 51 is formed of a cylindrical body, and the base end which is one end in the axial direction which is the left-right direction in FIG. 8 is welded and fixed to the guide portion 3 and is screwed inwardly. When the mounted bolt 52 is rotated, the socket 51 is not rotated, and the bolt 52 can be moved forward and backward with respect to the socket 51.

  Incidentally, in the fixing means 5 shown in FIG. 8, a bracket 53 is welded to the outer periphery of the socket 51 welded to the guide portion 3, and this bracket 53 is welded to the back surface of the guide portion 3. In addition, welding is also performed on the lower surface of the base end side portion of the beam member 1 that is close to the guide portion 3, thereby ensuring the integrity of the socket 51 with respect to the guide portion 3.

  On the other hand, in this fixing means 5, the bolt 52 has an axial direction left and right in FIG. 8, and a head (not shown) which is the left end in FIG. The contact part 54 which exhibits is contact | abutted and this contact part 54 is contact | abutted from the rooftop floor F side to the inner surface of the wall W (refer FIG. 1).

  Incidentally, the contact portion 54 is connected to and held by a base member 55 connected to the head of the bolt 52. Further, since the contact portion 54 is made of a rubber material in the drawing, the contact portion 24 is intentionally shown in a cross section in FIG. 8 so that this can be easily understood.

  The assembly column P is formed as described above, whereas the handrail H is formed as follows. That is, the handrail H basically has a predetermined mechanical strength that does not easily bend or deform even when the operator leans on the support column 4 that is in use, for example. For example, it may be made of iron or aluminum alloy, or may be made of hard synthetic resin.

  Further, as shown in FIG. 2, the handrail H is shown in FIG. 2 as a pair of upper and lower horizontal members 6 and 6 and a pair of left and right vertical members 7 connecting the upper and lower horizontal members 6 and 6. , 7 and a diagonal member 8 formed separately from the cross member 6 and the vertical member 7.

  The cross members 6 and 6 have vertical members 7 and 7 pivoted so that the vertical dimension during use is set. Gravity pins 41 (provided on the pillars 4) in the pin holes 6a (see FIG. 2) at both ends. 3) is inserted, it is assumed to be installed on the support column 4, that is, on the assembly support column P (see FIG. 1).

  And when the cross members 6 and 6 are connected to the support column 4, the diagonal member 8 is further connected to the support column 4 so that the handrail H is not deformed between the assembly support columns P, that is, It will be installed in a state where it will not be crushed.

  On the other hand, the handrail H can be installed on the column 4 even when the horizontal members 6 and 6 are formed to be extendable and the intervals between the assembly columns P are varied during use. In addition, as shown by a two-dot chain line diagram in FIG. 2, it is formed so as to be foldable, and can be made compact, and is excellent in transportability and storage property when not in use.

  Incidentally, the handrail H has a small diameter pipe (not shown) inserted into a large diameter pipe (not shown) so that it can extend and retract, and can be extended and contracted. It is assumed that it is practiced with a fastening tool (not shown) such as a butterfly bolt that is screwed to the outer periphery of the small diameter pipe. In response to the fact that the cross members 6 and 6 are formed to be stretchable, the diagonal member 8 is also formed to be stretchable in the same configuration as the cross members 6 and 6.

  Further, in the handrail H, the cross members 6 and 6 and the diagonal member 8 have the gravity pins 41 inserted through the holes 6a and 8a provided at both ends. As described above, the gravity pins 41 have the stoppers 41a. Therefore, the cross members 6 and 6 and the diagonal member 8 once having the gravity pin 41 inserted into the holes 6a and 8a are not separated from the support column 4 unless a so-called releasing operation of pushing the stopper 41a is performed.

The temporary handrail formed as described above is provided on the eaves wall W according to the following procedure. However, in the temporary handrail of the present invention, a procedure for providing the assembly strut P on the eaves wall W and an installation on the eaves wall W are provided. This is roughly divided into two steps: a procedure for installing the handrail H on the assembly post P.

  Therefore, first, the procedure for providing the assembly column P on the wall W will be described. For example, an operator on the roof floor F inside the wall W may protrude the locking portion 2 out of the wall W. Then, the beam member 1 is bridged from the inner side of the ridge wall W to the outer side of the ridge wall W on the upper end portion of the ridge wall W, and in this state, the ridge wall W is sandwiched between the locking portion 2 and the fixing portion 3. It becomes preparation to do.

  When the beam member 1 is bridged over the upper end portion of the wall W, the thickness of the wall W is known in advance, so the position where the locking portion 2 of the beam member 1 is fixed is selected. The stop 2 is positioned at a selected position in the beam 1 so as to correspond to the thickness of the wall W.

  In order to position the locking portion 2 on the beam member 1, the pin 23 is inserted into the pin hole 21a of the locking portion 2 and the pin hole 1a of the beam member 1 that is aimed at the pin hole 21a. Further, when the beam member 1 is bridged over the upper end of the wall W, the fixing means 5 is engaged with the fixing means 5 with the bolt 52 screwed into the socket 51 in the maximum stroke. The distance from the stop 2 is maximized.

  After the bridging of the beam 1 to the upper end of the wall W is completed, the contact portion 24 of the receiving portion 22 of the locking portion 2 is brought into contact with the wall W from the outside of the wall W, and in this state The bolt 52 in the fixing means 5 is rotated and advanced toward the locking portion 2, and the contact portion 54 at the tip of the bolt 52 is brought into contact with the collar wall W from the inner side of the collar wall W. By tightening, such as by using a tool, the anchoring wall W is clamped between the fixing means 5 and the locking portion 2, and the operation of providing the assembly support column P on the anchoring wall W is completed.

  In the present invention, since the column 4 is erected on the inner side of the wall W when the operation of providing the assembly column P on the wall W is completed, for example, in the conventional case disclosed in Patent Document 1 Compared to the above, the work up to the upright of the support column 4 can be performed quickly.

  In other words, in the conventional case disclosed in the above-mentioned Patent Document 1, the strut is not erected only by bridging the beam material on the wall, so the work of attaching the strut to the socket again, that is, Will be set up.

  On the other hand, in the case of the present invention, since the support post 4 is held by the guide portion 3 in advance, the guide post 3 is simply provided, that is, the assembly post P is attached to the wall W. It is only necessary to provide it, and the work of standing up the column 4 itself is not required.

  Since the assembly columns P need not be strict, a plurality of the assembly columns P are provided on the wall W at selected intervals, and the assembly columns P are connected by the construction of the handrail H. Then, next, although the setup of the installation to the assembly support | pillar P of the handrail H is demonstrated, it is sufficient if the handrail H is connected with the gravity pin 41 provided in the support | pillar 4. FIG.

  That is, for example, according to the place shown in FIG. 2, the gravity pin 41 may be inserted into the hole 6 a at one end which is the left end in FIG. 2 of the upper and lower cross members 6 and 6 forming the handrail H. Moreover, what is necessary is just to insert the gravity pin 41 in the hole 6a of the other end part used as the right end part in FIG. The same applies to the diagonal member 8.

  If the gravity pin 41 is inserted through the holes 6a and 8a, the stopper 41a automatically operates, so that the upper and lower horizontal members 6, 6 and the diagonal member 8 are removed from the support column 4 unless the stopper 41a is actively released. There is no separation.

  As described above, in the temporary handrail according to the present invention, when the assembly column P is provided on the wall W, the column 4 is previously positioned inside the wall W. The handrail H can be erected on the assembly column P, that is, the column 4 while being on the roof floor F inside.

  For this reason, for example, as in the case disclosed in Patent Document 1 described above, the support pillar is positioned outside the fence wall. Therefore, in order to prevent the handrail installed on the support pillar from falling for security reasons, Compared with the case where an operation of connecting a pulling member such as a rope is essential, the operation of connecting a pulling member such as a rope to the handrail H can be omitted, and workability can be improved.

  In addition, in the case of the disclosure in Patent Document 1 described above, since the column is attached to the socket outside the heel wall, the operator can avoid the heel wall from climbing up to the upper end of the heel wall. From this point of view, it is necessary to ensure the safety of the worker, but in this invention, the worker is on the rooftop floor F. Therefore, there is an advantage that the consideration becomes unnecessary.

  4, FIG. 5 and FIG. 6 show a state in which the temporary handrail of the present invention is provided on the wall W having another shape as in FIG. 1, and this will be described below. In each figure, when the configuration is the same as that shown in FIG. 1, only the same reference numerals are given in the figure, and the explanation is omitted unless necessary.

  First, FIG. 4 shows a state in which a temporary handrail is provided on the wall W where the thickness dimension is larger than that shown in FIG. 1. In the assembly column P in the temporary handrail, Assume that the locking portion 2 provided on the beam material 1 so as to be movable is positioned and fixedly fixed to the tip portion of the beam material 1 which is the right end portion in FIG.

  By positioning the locking portion 2 at the distal end portion of the beam member 1, the space between the fixing means 5 provided on the guide portion 3 is widened, and the temporary handrail of the present invention is applied to the wall W having a large thickness. It becomes possible to provide. Since the height of the ridge wall W is the same as that shown in FIG. 1, the height position of the column 4 with respect to the guide portion 3 connected to the beam 1 and the height position of the handrail H installed on the column 4. Will be the same.

  In the place shown in FIG. 5, the wall W is formed in a single wall state without an umbrella at the upper end compared to the place shown in FIGS. 1 and 4, and It is assumed that the height position of the upper end is increased. Incidentally, the thickness dimension of the eaves wall is supposed to be slightly smaller than the thickness dimension of the eaves wall W shown in FIG.

  Therefore, in the assembly support column P in the temporary handrail shown in FIG. 5, the beam member is arranged so that the engaging portion 2 provided movably on the beam member 1 is approximately similar to the case shown in FIG. Suppose that it is positioned near the center of 1 and fixedly fixed.

  On the other hand, in the assembly support column P shown in FIG. 5, the height position of the beam member 1 is higher than that shown in FIGS. 1 and 4 described above. Therefore, in order to make the height of the handrail H appropriate, the height position of the support column 4 with respect to the guide portion 3 is lowered.

  In addition, in the place shown in FIG. 5, it is supposed that the headboard B is provided above the upper end of the wall W, and therefore, in the assembly column P, the lower surface of the beam member 1 does not interfere with the headboard B. Yes.

  In the place shown in FIG. 6, compared with the place shown in FIG. 5 described above, the thickness dimension of the wall W is slightly reduced, while the height of the wall W is greatly reduced. For example, the wall W forms a so-called wall in order to avoid the inconvenience that rainwater collected on the rooftop floor F falls along the outer wall.

  And the temporary handrail of this invention shall be provided also in such a low ridge wall W, and in the assembly support | pillar P, the latching | locking part 2 is a position near the guide part 3 of the beam material 1. FIG. It is assumed that it is positioned and fixedly fixed.

  And in this assembly support | pillar P, since the guide part 3 will be provided as if it stood on the rooftop floor F, the support | pillar 4 which mounts the handrail H will raise to the maximum with respect to the guide part 3. It is assumed that the handrail H is positioned at a preferred height position. In addition, even in the place shown in FIG. 6, the headboard B is provided above the upper end of the ridge wall W, and therefore, the lower surface of the beam member 1 does not interfere with the headboard B in the assembly column P. .

  FIGS. 9 and 10 show a case where the temporary handrail of the present invention is provided in a protruding corner (not shown) on the roof of a building (FIG. 9) and a case where the temporary handrail is provided in a corner (not shown) ( FIG. 10) is shown below, and this will be described a little.

  Incidentally, since the exit corner and the entrance corner are generally configured at a right angle, it is assumed that the exit corner and the entrance corner are configured at a right angle in the following description. Further, the assembly column P has the same configuration as the assembly column P shown in FIG. 1 described above, and the wall W is also configured in the same manner as any of the above-described FIGS. 1, 4, 5, and 6. It becomes.

  First, as shown in FIG. 9, the assembly support column P in the temporary handrail is provided at the upper end portion of the eaves wall W so as to sandwich the protruding corner portion from the right side and the lower side in FIG. The other end side (not shown) of the handrail H on which one end side is installed on each assembly column P in FIG. 9 is installed on an assembly column P (not shown) provided on the wall W.

  On the other hand, in both assembly columns P provided at the upper end of the ridge wall W with the protruding corners sandwiched from both directions, the roof is positioned inside the ridge wall W and above the roof floor F. As shown in the figure, the F-side end portion can be prevented from slipping between the two by being adjacent to each other. Therefore, it is necessary to connect both the roof-floor F-side end portions with a connecting member. I can't say that.

  On the other hand, in the embodiment shown in FIG. 10, the temporary handrail is provided at the corner of the entrance, so it is necessary to connect the end portion on the roof floor F side of the assembly column P described above. That is, even when a temporary handrail is provided in the corner, as shown in FIG. 10, the assembly column P is provided at the upper end portion of the eaves wall W so that the corner is sandwiched from both directions. The space between the end portions on the roof floor F side of the column P is widened in a so-called angle shape to allow the operator to approach the wall W or to climb to the upper end of the wall W.

  It is not preferable from the viewpoint of security that the gap between the end portions on the roof floor F of both assembly columns P is widened and the operator is allowed to approach the wall W or climb to the upper end of the wall W. As shown also in FIG. 11, it is necessary to provide the auxiliary handrail H1 for closing the empty space.

  The auxiliary handrail H1 is basically similar to the handrail H described above, that is, is configured to be extendable and contracted so that it can correspond to the case where the above-mentioned empty widths are divided. Is said to be similar to the corner.

  The auxiliary handrail H1 includes a pair of horizontal members 61 and 61, and a pair of left and right vertical members 71 and 71 that are connected to the upper and lower horizontal members 61 and 61. 61, 61 are connected to the vertical members 71, 71 to set the vertical dimension during use to make the vertical shape rectangular (see FIG. 11), and are formed so as to be foldable. It is supposed to be in a two-bar shape.

  And in this auxiliary handrail H1, the gravity pin 41 (refer FIG. 3) provided in the support | pillar 4 is inserted in the hole (not shown) which exists in the edge part by the side of the assembly support | pillar P, and it is made to the support | pillar 4, ie, an assembly. It is supposed to be installed on the column P.

  Also, in this auxiliary handrail H1, it is assumed that the ends opposite to the ends having the above-mentioned holes are pivotally attached, and when the auxiliary handrail H1 is detached from the assembly column P, it can be folded. Yes.

  In addition, an arbitrary structure may be adopted to constitute the auxiliary handrail H1 that is paired on the left and right sides so that it can be folded, but not shown in the places shown in FIGS. In the hinge structure, both auxiliary handrails H1 are connected.

  Therefore, as described above, the temporary handrail (FIG. 10) provided at the corner of the building roof (FIG. 10) and the temporary handrail (FIG. 11) provided at the corner of the building roof. Even if it exists, since the assembly support | pillar P is comprised similarly to the case of embodiment mentioned above, the latching | locking part 2 provided in the beam material 1 spanned over the upper end part of the wall W, and a beam material By sandwiching the eaves wall W with the fixing means 5 provided in the guide portion 3 at the base end of 1, the assembly column P can be provided on the eaves wall W, and the guide portion 3 is attached to the base of the beam member 1. It becomes possible to position inside the wall W where the end is positioned.

  And since the guide part 3 is positioned inside the fence wall W, the support | pillar 4 currently hold | maintained at the guide part 3 will be positioned inside the fence wall W, and connecting the handrail H1 to the support | pillar 4 Thus, it is possible to provide a temporary handrail on the inner side of the ridge wall W at the protruding corner portion or the entering corner portion.

  Further, since the column 4 is positioned inside the wall W, the column 4 is positioned outside the wall W. Therefore, in order to prevent the handrail installed on the column from falling for security reasons, Compared with the case where the operation of connecting the traction member such as the rope to the hand is indispensable, the operation of connecting the traction member such as the rope to the handrails H and H1 is not required.

  Incidentally, even in this embodiment, by providing the assembly strut P on the collar wall W, the guide part 3 positioned inside the collar wall W holds the pillar 4, so the pillar 4 is held on the guide part 3. There is no need to work.

  Even in this embodiment, since the locking portion 2 is movable along the beam member 1, the thickness dimension of the wall W sandwiched between the fixing means 5 varies. In addition, this can be dealt with by selecting a fixing position of the locking portion 2 with respect to the beam member 1.

  When the fixing position of the locking portion 2 to the beam member 1 is, for example, a position closer to the center portion of the beam member 1, the so-called surplus portion that is so-called ahead of the locking portion 2 protrudes outside the wall W. Therefore, it does not become an obstacle inside the wall W.

  Furthermore, even in this embodiment, since the support column 4 is held by the guide portion 3 so as to be movable up and down, according to the height position of the guide portion 3, that is, according to the height position of the upper end of the wall W. Thus, the height position of the support column 4 can be raised and lowered, and the handrails H and H1 having a preferable height can be provided on the wall W having a different upper end height.

  As a result, according to this embodiment, it is possible to improve the workability when the temporary handrail is provided or removed, and even in this embodiment, the handrails H and H1 are provided. Since it is provided on the support column 4 held by the guide part 3 positioned inside the wall W, the handrails H and H1 are provided inside the wall W, and the handrail is positioned outside the wall. Compared to the case where the handrail is provided on the outside of the fence wall, it is possible to completely eliminate the room for a person to enter the upper end of the fence wall W, and the security by providing the handrails H and H1 is improved. It becomes possible to improve.

  In FIG. 1 and FIG. 4 described above, the eaves wall W has an umbrella at the upper end, and therefore the assembly column P is assumed to hold the umbrella between the locking portion 2 and the fixing portion 3. Instead, although not shown, of course, a so-called wall portion below the umbrella may be sandwiched between the locking portion 2 and the fixing portion 3.

  In the above description, the case where the temporary handrail according to the present invention is embodied in the roof wall W formed on the roof of the concrete building has been described as an example. Although the wall W is not formed on the roof, the wall W may be formed on the veranda, although not shown in the drawing, and it is needless to say that the operational effects in this case are not different.
