Description

  The present invention relates to a support structure for supporting a support for attaching a fence or the like upright on a foundation block, and a foundation block used for the structure.

In installation work such as a fence, a foundation block with a cavity inside is used to fix the support pillar for mounting the fence upright, and in conventional construction, the pillar is inserted into the foundation block and the height of the pillar is increased. After determining the length, the position of the column is fixed with a rope or a temporary fixing rod, the mortar is filled as it is, and the temporary fixing material is removed when the mortar is solidified.
In such construction, since the column is unstablely supported in the cavity of the foundation block, it is difficult to determine the position of the column and the work is troublesome. A structure has been proposed in which a single horizontal through hole is provided at the bottom of the frame, a support bar is inserted into the hole, and the support bar is placed on the upper end of the foundation block so that the height of the column can be easily determined. .
However, with the above-mentioned single support rod, there is a difficulty in that the column does not stand on its own and falls down in an unstable state as it tends to tilt left and right even if the height is determined.
For this reason, when constructing, fix it from the outside with a temporary fixing rod etc. so that the support does not move until the filled mortar solidifies, and at the same time wait for at least about one day until the mortar solidifies as it is After that, the temporarily fixed bar was removed, and the construction of the strut was finally completed. However, after that, the fence had to be installed, and as a result, the entire construction period took a long time.
On the other hand, as described in Patent Document 2, without using a rope or a temporary fixing rod, a pipe provided with an adjusting screw to be tightened from three directions in advance is fixedly embedded in a foundation block, and a column is attached to the pipe. There has been proposed a structure in which the column can be fixed in an upright state by standing and tightening the column from three directions with an adjusting screw.
JP 2004-36202 A JP 10-325268 A

The fixing by the adjusting screw described in Patent Document 2 has an advantage that the work period can be shortened because the support can be self-supported on the foundation block, but on the other hand, the tilt angle and the arrangement position of the support can be corrected. There was a problem that the adjustment width was small and the construction accuracy was limited, and the adjustment of the column with the adjustment screw was troublesome, and the adjustment screw was exposed in the lower part of the column after completion, so that it looked bad.
Therefore, in view of the above-mentioned problems, the present invention can simultaneously realize the placement of the pillars on the foundation block with high accuracy and the shortening of the construction period and the construction cost of the entire construction for attaching the fence, etc. It is an object of the present invention to provide a support structure for a support in a foundation block with good appearance and a foundation block used for an upright support structure for the support.

In order to solve the above-mentioned problems, the support structure for supporting a column according to the present invention includes a column part having two slide pins at the lower part of the column body, and a mortar filled after the lower part of the column body is inserted. It is the support structure of the upright of the support | pillar which consists of a basic block part provided with the vertical elongate cavity for fixing upright.
The column portion is provided with two through-pin holes perpendicular to the center line of the column main body at a lower portion of the column main body, and two slide pins shorter than the lateral width of the base block portion in the through-pin hole. It is configured to pass through.
The base block portion is a portion of a lower portion of each end of both slide pins or a portion where the lower side of one slide pin is in contact with the upper side of the other slide pin when the column main body is vertically inserted into the cavity. A horizontal slide guide surface disposed on the inner wall surface of the cavity, a slide space in which the slide pin in contact with the slide guide surface is movable in the horizontal direction, and an end portion of the slide pin facing the slide space The pin support part provided with the contact | abutting guide wall standingly arranged in parallel with respect to the other slide pin is provided in the site | part which hits.
The slide guide surface of the foundation block part supports a slide pin on the support part so that the support part can be moved horizontally to the foundation block part in a self-supporting state.

The invention according to claim 2 is a foundation block used for the upright support structure of the support according to claim 1.
The foundation block of the present invention vertically inserts the lower part of the pillar body vertically into the cavity of the foundation block in order to support the pillar part with the slide pin loosely inserted in the through pin hole provided in the lower part of the pillar body. A horizontal slide guide surface disposed on a hollow inner wall surface of a portion where the lower side of each end of both slide pins or the lower side of one slide pin and the upper side of the other slide pin are in contact with each other, and the slide guide A slide space that allows the slide pin in contact with the surface to move in the horizontal direction, and a portion that faces the slide space and the end of the slide pin abuts in parallel with the other slide pins A pin support portion P having a contact guide wall is provided.

  The invention according to claim 3 includes a sandwiching guide surface that is vertically opposed to one or both of the slide guide surfaces so that the slide pin can be sandwiched between the slide guide surfaces in the configuration of the basic block, A slide groove surrounded by the clamping guide surface, the slide guide surface, and the contact guide wall is formed.

  According to a fourth aspect of the present invention, in the configuration of the basic block, the slide pin is limited by restricting a rotational movement range of the slide pin by rotation of a supporting column inserted on both sides of each slide space facing the slide guide surface. A rotation stop portion is provided to prevent the slide pin from falling off the guide surface.

  According to a fifth aspect of the present invention, in the configuration of the basic block, a guide surface connected to the slide guide surface is provided at a corner portion of the hollow inner wall surface connected to the slide guide surface in contact with the lower side of the end portion of the slide pin. A pin introduction guide base is formed.

Since the present invention has the above-described configuration, when the support column is inserted into the foundation block portion embedded in the ground at regular intervals, the slide pins are perpendicular to the through-pin holes of the support column portion by the slide guide surfaces of the foundation block portion. Of the struts that are self-supporting vertically with respect to the base block, even if the strut body position is misaligned and the column row is disturbed, the misaligned strut body remains self-supporting and remains in the horizontal direction. It can be easily moved and corrected significantly.
That is, when correcting the disturbance of the column of columns, such as a fence, when the support is held and pushed in the horizontal direction, the slide pin in contact with each slide guide surface is brought into contact with the slide guide surface. The tip of the slide pin abuts against the guide wall and is restrained and simultaneously slides into the through pin hole and moves horizontally in each slide space C. The lower part of the column main body is horizontally limited within the cavity of the foundation block The position can be corrected while remaining independent.

In this way, it is possible to correct the struts to the correct positions on each foundation block and make them stand upright vertically, so even before fixing the struts with mortar during construction, the fence to the strut body as the next step The attachment process can be performed continuously without waiting for time.
Because of this, in each conventional block, each pillar cannot be fixed vertically unless the mortar is filled with mortar, so the fence could not be attached until at least one day until the mortar solidified. Compared with, the construction period can be greatly shortened.
Furthermore, in the present invention, there is no temporary fixing step using a temporary fixing rod until the mortar is solidified, and materials for temporary fixing are not required, so that material costs and labor costs are reduced accordingly.

In addition, until now, it was not possible to proceed to the fence installation process without filling the mortar and fixing each column vertically, so the position of each column after that and the position of each column after the fence was installed were corrected. The correction was made without digging up the entire foundation block and replacing it with a new foundation block and support. This position correction work was very troublesome.
On the other hand, in the present invention, the vertical support of the column main body can be maintained without filling the mortar, and the fence mounting process can be continuously performed as it is. If it is performed before filling, the column portion is not fixed to the foundation block portion, so that the position can be corrected very easily. In addition, since it is possible to finally modify the exact position of the columns where the fence-attached support columns are arranged, it is possible to cleanly work so that the center line is in a straight line.

Further, in the form in which the slide groove is formed on the slide guide surface, the slide pin does not pull out directly upward, so that there is no fear of the support column falling down even if it is not fixed by filling with mortar. The column part cannot be pulled out from the block at all.
This is because in the conventional foundation block, the support pillar can be easily pulled out from the foundation block due to slackening of the support pillar due to solidification shrinkage of the mortar, and there was damage to the fence etc., to prevent such mischief Also become.
In addition, since the cavity is finally filled with mortar, the upper surface portion of the basic block after completion is refreshing and looks good.

Embodiments of an upright support structure for a column of the present invention and a foundation block used for the structure will be described below.
In the upright support structure of the support column of the present invention, the support column part 2 (shown in FIG. 1A) having two slide pins 3 and 4 at the lower part of the support column body 2a and the lower part of the support column body 2a are inserted. It is composed of 1 part of a concrete base block (shown in (b) in FIG. 1) provided with a vertically long rectangular cavity S for filling the column part 2 upright by filling with mortar later.

The slide pin holes 9a and 10b are provided so as to intersect with each other at an angle of 90 degrees, and two slide pins 3 and 4 having a length M shorter than the lateral width L of the base block 1 part are passed through the through pin holes 9a and 10b. The slide pins 3 and 4 are configured so as to freely appear and disappear in 9a and 10b.
The column portion 2 can be a pipe or a rod having a large diameter, and a U-shaped or L-shaped one is not suitable for smooth horizontal movement as it is, as shown in FIG. Another steel plate or L-shaped steel material is overlapped and processed into a cylindrical shape for use.

The base block 1 part is inserted into the cavity S for inserting the lower part of the support column 2a and filling the mortar to fix the support column 2 upright. A pin support portion P for supporting the point is provided.
As shown in FIG. 1B, the pin support portion P is a portion where the ends of the slide pins 3 and 4 are in contact with each other when the lower portion of the column main body 2a is vertically inserted into the cavity S. The horizontal slide guide surfaces 7a, 7b, 8a provided on the inner wall surface 1a of the cavity and the slide pins 3, 4 in contact with the slide guide surfaces 7, 8 can be freely moved in the horizontal direction within a certain range. The slide space C and the lengthwise movement of both ends of the slide pins 3 and 4 can be constrained to the portion where the end of the slide pins 3 and 4 hits the depth portion in the cavity facing the slide space C. Abutting guide walls 5a, 5b, 6a are provided in parallel with other slide pins.
The slide guide surfaces 7a, 7b, and 8a are formed on the cavity inner wall surface 1a at the portion where the lower sides of both ends of the slide pins 3 and 4 are in contact with each other when the column body 2a is vertically inserted into the cavity S. Cavity inner wall surface 1a at the position where the arranged mode (shown in FIG. 2), the lower side of one slide pin 3 (reference numeral 22a, 22b in the figure) and the upper side of the other slide pin 4 (reference numeral 23a in the figure) are in contact. (See FIG. 9).
The main body portion of the concrete base block 1 may have a prismatic outer shape or a cylindrical shape as shown in FIG.

  In the structure of the present invention, as shown in FIG. 4, when the slide pins 3 and 4 of the support column 2 are mounted on the slide guide surfaces 7a, 7b, 8a and 8b of the base block 1 part, As shown in FIGS. 4 (a) and 4 (b), the column 2 is supported at four points on each end of the slide pin 3 and 4 and stands upright in a self-supporting state. In addition, the slide pins 3 and 4 are constrained by contact with the contact guide walls 5a, 5b, 6a and 6b, and the slide pins 3 and 4 are freely moved in the horizontal direction while protruding and retracting in the through-pin holes 9a, 9b, 10a and 10b. It becomes possible to move to.

Next, the basic block used for the upright support structure of the column will be described.
As shown in FIG. 1B, the base block 1 is a pillar in which slide pins 3 and 4 are loosely inserted into through-pin holes 9a and 10b provided in the lower part of the pillar body 2a in the cavity S of the base block 1. A pin support portion P is provided to support the portion 2 upright.
The pin support portion P is arranged on the cavity inner wall surface 1a at the portion where both ends of the slide pins 3 and 4 are in contact with each other when the lower part of the support body 2a is vertically inserted into the cavity S of the basic block 1. Horizontal slide guide surfaces 7a, 7b, 8a provided, a slide space C that allows the slide pins 3, 4 in contact with the slide guide surfaces 7a, 7b, 8a to move in the horizontal direction, and the slide space C And abutting guide walls 5a, 5b, 6a that are erected in parallel to the other slide pins at a portion where the ends of the slide pins 3, 4 abut.
The slide guide surfaces 7a, 7b, 8a are arranged on the inner wall surface 1a of the cavity where the lower sides of both ends of the slide pins 3, 4 contact each other when the column main body 2a is vertically inserted into the cavity S. There are a mode (shown in FIG. 2) provided and a mode (shown in FIG. 9) arranged on the cavity inner wall surface 1a at the portion where the lower side of one slide pin 3 and the upper side of the other slide pin 4 are in contact.

As shown in FIG. 2 (B), the mode in which the lower side of each end of both slide pins 3 and 4 is in contact with the hollow inner wall surface 1a is the top of both slide guide surfaces 7a, 7b and 8a. The slide pins 3 and 4 can be mounted on the upper side of the slide space C, and the upper side of the slide space C can be opened.
In this embodiment, as shown in FIG. 2, it is only necessary to place the slide pins 3 and 4 at the lower part of the column main body 2a directly from above at the time of construction.

In addition, as shown in FIGS. 10 (A) and 10 (B), the upper slide is arranged in the cavity inner wall surface 1a where the lower side of one slide pin 3 and the upper side of the other slide pin 4 are in contact. A mode in which the lower side of the pin 3 and the upper side of the lower slide pin 4 are disposed on the hollow inner wall surface 1a at the portion in contact with the slide guide surfaces 24a, 24b, 25a, and as shown in FIGS. There is an embodiment in which the lower side of the pin 3 and the upper side of the upper slide pin 4 are arranged on the hollow inner wall surface 1a at a portion where the upper side is in contact with the upper side.
In any of the above embodiments, the space forming surface 21 can be provided on the upper and lower surfaces of each slide guide surface to secure the slide space C.
Further, in the aspect in which the lower side of the upper slide pin 3 and the upper side of the lower slide pin 4 are disposed on the hollow inner wall surface 1a in contact with the slide guide surface, as shown in FIG. 27 can be formed at the same height with stepped surfaces having different depths.
In this case, the lengths of the two slide pins 3 and 4 are different, but the upright support 2 can be supported even if it is rotated by 90 degrees. There is no need to do it.

The slide guide surfaces 7a, 7b, 8a, and 8b can be formed of a metal plate or a synthetic resin plate having a higher planar accuracy than a concrete material, as shown in FIG.
The difference in height between the slide guide surfaces 7a, 7b, 8a, 8b is the case (shown in FIG. 2) in which the slide guide surfaces 7a, 7b, 8a, 8b are arranged on the cavity inner wall surface 1a at the part where the lower sides of both ends of the slide pins 3, 4 are in contact. As shown in FIG. 1 (a), the height H equal to the diameter R of the slide pins 3 and 4 has a height difference (shown in FIG. 14) higher than that, and the column portion is made corresponding to the height difference. The height difference of both pairs of the through pin holes 9a and 10b is formed.
Assuming that this height difference is a height H equal to the diameter R of the slide pins 3 and 4, as shown in (a) and (b) of FIG. The slide pins 3 and 4 come into contact. The movement of the slide pins 3 and 4 is suppressed by the frictional resistance due to this contact, and the position of the support column is not easily changed when the positioning is performed.
On the other hand, as shown in FIGS. 14A and 14B, this height difference can be made larger and lower than the diameter of the slide pins 3 and 4. In this case, the height difference between both pairs of the through-pin holes 9a and 10b of the support column is formed corresponding to the height.
The distance between the opposing abutment guide walls 5a, 5b, 6a is the distance at which both ends of the slide pins 3, 4 of the supporting column abut and is substantially equal to the length of the slide pins 3, 4, and the slide pins 3, 4 Are formed slightly longer than the slide pins 3 and 4 so as to be reciprocally movable.

Further, as shown in FIGS. 5A and 5B, the slide pin 3 can be moved up and down on one or both of the slide guide surfaces 7a, 7b, 8a and 8b with the slide guide surfaces 7a, 7b and 8a. It is possible to form the slide grooves 13 and 14a provided with the clamping guide surfaces 11a, 11b and 12a that can clamp 4.
In this embodiment, as shown in FIGS. 5A and 5B, the foundation block 1 has a vertical cavity S therein, and is the same as the height intermediate portion of the inner wall surface 1a in the cavity S. Two pairs of horizontal slide guide surfaces 7a, 7b, and 8a facing each other at 90 degrees in the high direction are formed so that both facing surfaces are stepped up and down.

In this embodiment, as shown in FIG. 6, since the slide pins 3 and 4 are supported by the slide grooves 13 and 14a, they are not pulled straight up, so that the support 2 is not only self-supporting. Since it does not fall over, there is an advantage that a fence can be easily attached before filling with mortar.
The slide grooves 13a, 13b, 14a, and 14b have the height difference of the upper and lower steps of the slide guide surfaces 7a, 7b, 8a, and 8b of the base block 1 substantially equal to the diameter of the slide pins 3 and 4, and the height thereof. The height difference between the pair of through-pin holes 9a, 9b, 10a, 10b of the support column 2 is formed corresponding to the two, and the two slide pins 3, 4 are in contact at the intersection of the inserted slide pins 3, 4 By doing so, the determined position can be made more stable.
As shown in FIG. 7, slide grooves 15a, 15b, 16a, 16b made of metal or synthetic resin having a U-shaped cross section can be embedded in the peripheral surfaces of the slide grooves 13a, 13b, 14a, 14b. It is.
In this way, it is easy to manufacture the foundation block as a concrete product by biting the slide groove 15a, 15b, 16a, 16b as it is when manufacturing, and the strength of this part is also increased. There is an advantage that can be improved.

Also, the method of mounting the slide pins 3 and 4 in the slide grooves 13a, 13b, 14a, and 14b is that the slide pins 3 and 4 are placed in the slide grooves 13a, 13b, 14a, and 14b only by placing them directly below. Therefore, the slide pins 3 and 4 are temporarily rotated near the diagonals of the square in the slide space C toward the both end portions of the slide guide surfaces 7a, 7b, 8a and 8b of the base block 1. Then, it is dropped from above the base block and rotated again at a position corresponding to the height of the slide guide surfaces 7a, 7b, 8a, 8b having the different upper and lower steps, and as shown in FIG. The ends of the slide pins 3 and 4 in 13b, 14a and 14b are fitted and attached.
However, the lengths of the diagonal lines of the four corners in the vertical cavity S are shorter than the lengths of the slide pins 3 and 4, and the slide pins 3 and 4 extend from the diagonal lines into the slide grooves 13a, 13b, 14a and 14b. 15, if the upper part of the slide grooves 13 a, 13 b, 14 a, 14 b of the basic block portion 1 is opened wider and vertically than the diameter of the slide pins 3, 4, as shown in FIG. By forming the drop groove 17, it is possible to guide the slide pins 3 and 4 from the pin drop groove 17 to the slide grooves 13a, 13b, 14a and 14b.

Further, as shown in FIG. 1B, the slide pins 3 and 4 are rotated by the rotation of the column portions 2 inserted on both sides of each slide space C facing the slide guide surfaces 7a, 7b, 8a and 8b. It is also possible to provide an anti-rotation portion 18 that limits the rotational movement range and prevents the slide pins 3 and 4 from falling off the slide guide surfaces 7a, 7b, 8a, and 8b.
In this case, when the support column 2 is rotated in the square cavity S, when the slide pins 3 and 4 reach close to the diagonal of the square, they slide from both ends of the slide guide surfaces 7a, 7b, 8a and 8b. In order to prevent the pins 3 and 4 from falling, as shown in FIG. 1B, the column main bodies 2a are provided at both ends of the slide guide surfaces 7a, 7b, 8a and 8b of the foundation block. It is preferable to provide an anti-rotation portion 18 that restricts the rotation range of the slide pins 3 and 4 by the rotation of.
Further, as shown in FIG. 14, the horizontal slide guide surfaces 7a, 7b, 8a, and 8b may have a small width when the minimum movement width is sufficient. Since the rotation range of the pins 3 and 4 is narrow, the rotation stopper 18 is formed with a narrow width.
As shown in FIG. 4 (c), the rotation stop portion 18 cannot be rotated to near the diagonal of the square in the cavity S, so that the slide guide surfaces 7a, 7b, 8a, 8b The slide pins 3 and 4 can be prevented from falling off.

Further, as shown in FIGS. 19A and 19C, the corner portion of the hollow inner wall surface 1a connected to the slide guide surfaces 7a, 7b, 8a, 8b in contact with the lower side of the end portions of the slide pins 3, 4 is provided. It is also possible to form a pin introduction guide base 19 having a guide surface connected to the slide guide surfaces 7a, 7b, 8a, 8b.
In this embodiment, the slide guide surfaces 7a, 7b, and 8a, such as an aspect in which the upper portion of the slide space C is not opened, that is, an aspect in which the space forming surface 21 is provided on the upper and lower surfaces of the slide guide surface to secure the slide space C, etc. 8b, the pin introduction guide base 19 is provided at the corner portion, so that the slide pin 3 to the slide guide surfaces 7a, 7b, 8a, 8b when the column portion 2 is inserted into the cavity S of the foundation block. 4 can be easily mounted by rotating the support column 2 on the pin introduction guide base 19.
The pin introduction guide base 19 is preferably formed with a horizontal guide surface on a surface continuous with the slide guide surfaces 7a, 7b, 8a, 8b.
The slide guide surfaces 7a, 7b, 8a, and 8b may be slightly higher than the slide guide surfaces 7a, 7b, 8a, and 8b. If the guide surface is inclined downward, it can be smoothly led to the slide guide surfaces 7a, 7b, 8a, 8b.

Next, construction for attaching a fence will be described.
First, the foundation block 1 is buried and arranged at regular intervals on the ground G (shown in FIG. 17A), and then the metal pipe for attaching the fence F is placed in the cavity S of the foundation block 1 buried. The slide pins 3 and 4 inserted into the through-pin holes 9a, 9b, 10a, and 10b are inserted on the slide guide surfaces 7a, 7b, 8a, and 8b to be self-supporting (shown in FIG. 17B). ).
At this time, as shown in FIG. 20, if the center mark groove 20 is provided in the cavity S, it becomes easy to align the column part 2 at the center of the cavity S at the position of the slide pins 3 and 4.
And the fence F is attached to the support | pillar part of metal pipes (shown in (c) of FIG. 18).
At this time, if the alignment of each of the basic block portions 1 has occurred, the column main body 2 is corrected to an accurate position. In this modification, when the column main body 2 is pushed and pulled, the through-pin holes 9a, 9b, 10a and 10b and the slide pins 3 and 4 slide, and at the same time, the contact guide walls 5a, 5b and 6a, which hit the depth of the stepped surface, While being constrained by 6b, it is corrected by moving horizontally within the cavity S of the base block 1 so that the slide pins 3, 4 slide on the horizontal slide guide surfaces 7a, 7b, 8a, 8b.
When the position can be determined, finally, the mortar M is filled into the cavity S and each support is fixed vertically (shown in FIG. 18D).

In the present invention, since the vertical support of each column main body 2 can be maintained on each foundation block 1 in this way, the process of attaching the fence F to the column main body 2 as the next step is continued before filling with mortar. Can be performed.
This is a significant reduction in the work period compared to the conventional method of waiting for at least one day until the mortar solidifies to fill the mortar and fix it vertically. Can be realized.
Further, since there is no temporary fixing step with a temporary fixing rod or the like until the mortar is solidified as in the prior art, no material for temporary fixing is required.

The upright support structure of the column of the present invention and the basic block used for the structure are the above structures,
In addition to the installation of fences, it can also be used for installation of various supports such as signs, fence posts, guardrail supports.
