Description

TECHNICAL FIELD The present invention relates to a pillar installation method, a carport installation method, a pillar structure, and a carport, which can install pillars at appropriate angles easily and inexpensively regardless of the state of foundation construction.

For example, when installing a structure such as a carport, a pillar such as a metal square pillar (column) or cylinder (pipe) is erected as a foundation, and beams are placed on it, then a metal or resin roof is installed. Construction is carried out in the order in which the boards are installed.

By the way, in areas where snow falls on the carport, the weight of the snow piled up on the roof shingles made of aluminum may cause the carport to collapse. In this case, cars parked under the shingles may be damaged, so iron shingles are often used instead of aluminum shingles. Columns must be strong enough to support the weight of iron roof shingles, so even carports adopt a column structure that can withstand a large load. For example, in some cases, a structure in which iron columns are inserted into the concrete foundation is adopted. In addition, as disclosed in Patent Document 1, the installation of solar panels on a carport may cause the roof to become a heavy object. Occasionally, it becomes necessary to increase the thickness of the pillars, increase the wall thickness of the pillars, or create a structure in which the pillars are deeply buried in the foundation.

JP 2021-14764 A

If you try to build a carport with an existing steel frame structure using such a column structure, you will need to prepare expensive steel columns higher than the roof height and bury them in the foundation.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present invention should not be limited to these embodiments in any way, and can be implemented in various forms without departing from the spirit of the present invention.

<<First embodiment>>
<Description of carport>
FIG. 1 is a perspective view showing the carport of the first embodiment. FIG. The carport 100 includes a foundation 1 mostly buried in the ground, a plurality of columns 2 having a column structure as described later, a plurality of beams 3 provided on the upper end side of the plurality of columns 2, and a plurality of beams. 3 and a roof shingle 4 which is a corrugated sheet. Each part except the foundation 1 in this embodiment is made of iron as an example, and can be adopted as a structure that can withstand the load due to accumulated snow in a heavy snowfall area. Although not shown in FIG. 1, a fascia or a gable board provided on the outer circumference of the roof panel 4 may be attached. In the carport 100, a car is parked under the roof plate 4. - 特許庁

As a method of installing such a carport 100, there are a step of installing a plurality of pillars (columns) 2 on a foundation 1 by a step to be described later, and a step of installing a plurality of beams 3 on the upper end side of the installed plurality of columns 2. and a step of providing the roof shingles 4 on the plurality of beams 3 can be adopted.

<Description of the pillar installation process>
FIG. 2 is a flowchart for explaining the pillar installation process. The installation method of the pillar in this embodiment includes each process from process S1 to process S9 mentioned later. Each step may be replaced or omitted unless it is practically impossible.

FIG. 3 is a sectional view showing the structure of the foundation on which the pillars are installed. The foundation 1 is a so-called footing foundation. More specifically, the foundation 1 includes a lower footing 10 provided deep in the ground to support the load from the upper structure, and an upper footing 11 provided on the upper part of the footing and partially exposed to the ground. Constructed mainly of concrete to contain Since the footing lower portion 10 is formed wider than the footing upper portion 11, the foundation 1 has an inverted T-shaped cross section. As a result, the supporting force of the ground can be widely received, and the posture can be stabilized by the self-weight of the ground. A central reinforcing bar 12, a stanchion 13, and a bar arrangement 14 are provided so as to be partly buried in the footing upper part 11.例文帳に追加The central reinforcing bar 12 has a structure in which its lower end is also buried in the footing lower portion 10 . As described above, in the column structure of the present embodiment, a reinforcing bar structure extending from the foundation 1 to the upper part is formed.

The central reinforcing bar 12 is provided substantially in the center of the foundation 1 so as to be buried inside the foundation 1 on the lower end side. Further, the central reinforcing bar 12 can also be used for positioning the stanchions 13 and the bar arrangement 14 as the reinforcing bar of the column structure in this embodiment. For example, by setting the central reinforcing bar 12 at the correct position in accordance with the design of the entire structure, the stanchions 13 and the reinforcing bars 14 can be easily positioned and installed. Note that the central reinforcing bar 12 does not necessarily have to be provided.

A stanchion (“first column” in the present invention) 13 is a square pipe made of iron having a cylindrical shape, and is open at the top and bottom. The stanchion 13 is provided substantially in the center of the foundation 1 so as to be embedded in the foundation 1 by the thickness of the footing upper portion 11 in the height direction on the lower end side. The lower part of the stanchion 13 is supported by the footing upper part 11 so that the stanchion 13 is stably erected, and is used for adjusting the angle of the column 2, which will be described later. The stanchion 13 may be stabilized inside the upper footing 11 by providing an anchor (not shown) so as to stand laterally from the outer peripheral side surface of the stanchion 13 .

In addition, in the description of the present embodiment, the configuration and effects will be described on the assumption that the construction state of the foundation 1 is not good. More specifically, as shown in FIG. 3, the stanchion 13 is tilted by θ degrees from the vertical direction (the Z-axis direction indicated by the two-dot chain line in FIG. 3) at its center line (one-dot chain line in FIG. 3). example. It goes without saying that even when the stanchion 13 is erected in the vertical direction, the same effect as that of the present embodiment can be obtained.

The reinforcing bars 14 are reinforcing bars erected so as to surround the outer periphery of the stanchions 13, and have the function of connecting the foundation 1 and structural members (members) provided thereon. The bar arrangement 14 is provided so as to be embedded in the foundation 1 so as to be concentric with the stanchions 13 . More specifically, the bar arrangement 14 has a structure in which the lower end side thereof is bent toward the outside of the foundation 1 and embedded in the footing upper part 11 . The reinforcement arrangement 14 includes not only a plurality of reinforcing bars extending vertically on the foundation 1, but also reinforcing bars extending horizontally so as to be orthogonal to them.

In the pillar installation method of the present embodiment, first, in step S1 shown in FIG. FIG. 4 is a cross-sectional view showing a state in which the springback plate is fixed to the stanchions. The springboard 15 is a tubular iron member (a “tubular member” in the present invention) whose inner diameter is larger than the outer diameter of the stanchion 13 . The springback plate 15 is provided to facilitate pressing of a bolt 22 (see FIG. 8) on the column 2 side, which will be described later. Note that the springback plate 15 may be configured as shown in FIG. 15, which will be described later.

The springboard 15 in this embodiment has a cylindrical shape with a rectangular cross section in the axial direction, and as shown in FIG. As a result, the rebound plate 15 is configured in a shape such that the outer diameter of the other end side (for example, the lower side) is larger than that of the one end side (for example, the upper side) as a whole. One end side of the rebound plate 15 has an inner diameter slightly larger than the outer diameter of the stanchion 13 (for example, a dimension larger by several millimeters), so that the rebound plate 15 can be smoothly inserted into the stanchion 13. is configured as

A bolt hole 15a is formed on one end side (part of) of the springboard 15. As shown in FIG. By screwing a bolt 16 as a fastener into the bolt hole 15a, the springboard 15 is fixed at an arbitrary height position on the stanchion 13. As shown in FIG. FIG. 4 shows a configuration in which a plurality of bolt holes 15a are provided. Further, as a method of fixing the springboard 15 to the stanchion 13 , a wedge may be inserted between the springboard 15 and the stanchion 13 instead of using the bolt 16 . In this way, the spring plate 15 can be fixed to any position on the stanchion 13 by means of fasteners, thereby facilitating alignment with the bolt holes 21 of the column 2, which will be described later.

On the other hand, the other end side of the rebound plate 15 has a larger outer diameter and is wider than the stanchion 13 when viewed from the side (X-axis direction or Y-axis direction) (see FIG. 10). As a result, even if the bolt 22 screwed from the outside of the column 2 toward the stanchion 13 is displaced from the stanchion 13, the bolt 22 can be reliably pressed against the springback plate 15. - 特許庁In this case, the bolt 22 indirectly receives a reaction force from the stanchion 13 via the springback plate 15 .

By using such a springboard 15, it becomes unnecessary to use an iron pipe that is thicker than necessary as the stanchion 13, and the cost of the column structure can be reduced. Alternatively, the stanchions 13 may be thickened to make it easier for the bolts 22 to be pushed against them, so that the springback plate 15 is not provided.

Subsequently, in step S2 shown in FIG. FIG. 5 is a cross-sectional view showing a state in which the stanchions are filled with a filler. In this step, the filler 17 is injected from the opening at the upper end of the stanchion 13 as indicated by the arrow in the figure. Thereby, the central reinforcing bar 12 and the stanchions 13 can be integrated to increase the strength. In addition, even if pressure is applied to the stanchions 13 from the sides, the structure can be such that the filler 17 can withstand the pressure.

The filler 17 is, for example, concrete or mortar milk (hereinafter sometimes simply referred to as "mortar") that hardens over time. Concrete and mortar are made by mixing aggregates such as sand and gravel with cement paste, which is made by dissolving and mixing cement, which is a hardening agent, with water. Concrete and mortar harden over time as cement solidifies.

Subsequently, in step S3 shown in FIG. 2, the worker places a wooden frame (“reference frame” in the present invention) 18 surrounding the stanchions 13 on the foundation 1 having the stanchions 13 . FIG. 6 is a cross-sectional view showing a state in which the wooden frame is installed on the foundation. The wooden frame 18 is formed by combining lumber such as plywood to have dimensions slightly larger than the external dimensions of the column 2 and in the shape of a rectangular frame when viewed from above. This serves as a reference for determining the position and angle for inserting the column 2, which will be described later. The crate 18 is temporarily secured to the foundation 1 by fasteners such as bolts 19 . In this case, the wooden frame 18 may be formed to have a rectangular cross-sectional structure as shown in FIG. Any configuration may be employed as long as a surface is provided.

The wooden frame 18 is provided substantially concentrically with the stanchion 13, but if the position of the stanchion 13 deviates from the design of the entire structure, the wooden frame 18 can be installed at a position that matches the design. , the column 2 can be installed in the correct position in terms of design. According to this, even if the position where the foundation 1 (particularly, the stanchion 13) is installed is slightly deviated, the construction work can be continued, and the progress of the construction work is not hindered.

The wooden frame 18 also has the function of preventing the filler 24 from leaking from between the lower end surface of the column 2 and the foundation 1 when the filler 24 is injected into the column 2, as will be described later with reference to FIG. . In this case, if there is a gap between the lower end surface of the column 2 and the surface of the foundation 1 due to reasons such as the foundation 1 being tilted, the gap is filled with a plate material such as plywood or plywood to prevent the filler 24 from leaking. You may

Next, in step S4 shown in FIG. 2, the worker inserts the column 2 into the wooden frame 18. As shown in FIG. FIG. 7 is a cross-sectional view showing a state in which the column is installed on the foundation. In this process, the column 2 is inserted between the wooden frame 18 and the stanchion 13 as shown in the figure. In this state, the column 2 is erected at an angle that matches the upper surface of the foundation 1 (more specifically, the upper surface of the footing upper portion 11), so it may not be erected vertically.

The column (“second column” in the present invention) 2 is a bottomless tubular iron square pipe (iron pipe), and is open at the top and bottom. The column 2 is provided with a tapped bolt hole 21 at a position corresponding to the stanchion 13 . More specifically, the column 2 is formed with a bolt hole 21 at an axial position overlapping the upper end of the stanchion 13 when the column 2 is installed on the foundation 1 . For this reason, the bolt holes 21 are formed at positions within a range not exceeding the length of the stanchions 13 on the foundation 1 with the end face of the column 2 as a reference, for example. In addition, the bolt holes 21 are formed at substantially central positions in the width direction on each of the four side surfaces of the column 2 (see FIG. 10), so that a total of four bolt holes 21 are formed. With such a configuration, it is possible to dispose the bolt hole 21 at the same height as the lower end side of the springboard 15 as shown in FIG.

Subsequently, in step S5 shown in FIG. 2, the operator adjusts the angle of the column 2 by screwing the bolt 22. As shown in FIG. In this process, a bolt 22 is screwed into the bolt hole 21 from the outside of the column 2 and pressed toward the stanchion 13, and the amount of screwing of the bolt 22 is used to adjust the angle at which the column 2 is erected.

Here, as described above, since the inner diameter of one end side (upper side) of the rebound plate 15 is configured to be slightly larger than the outer diameter of the stanchion 13 , the rebound plate 15 does not rattle with respect to the stanchion 13 . I try not to More specifically, even if force is applied to the springboard 15 by pushing the bolt 22 from the outside of the column 2 , it is possible to prevent the springboard 15 from tilting with respect to the stanchion 13 . As a result, it is possible to align the column 2 with the stanchion 13 even if the springback plate 15, which is separate from the stanchion 13, is used.

FIG. 8 is a cross-sectional view showing a state in which the bolt is screwed into the column. The bolts 22 are screwed from four directions into the bolt holes 21 on each side surface of the column 2 . In this state, the tip of the bolt 22 is pressed against the springback plate 15 . In order to adjust the angle of the column 2, first, a plumb bob 23 indicated by a chain double-dashed line in FIG. The plumb bob 23 has a structure in which a fixed portion that can be fixed to an object and an inverted conical weight are connected with a string, and the verticality of the object can be easily determined by measuring the distance between the object and the string. can be measured to Since the angle of the column 2 is not vertically adjusted at the stage of FIG. 8, the side surface of the column 2 and the thread of the plumb bob 23 are different on the upper end side and the lower end side. More specifically, the thread is close to the side surface of the column 2 on the lower end side. This confirms that the column 2 is tilted.

Subsequently, in step S5, the screwing amount (tightening amount) of the bolt 22 is adjusted to adjust the angle of the column 2 with respect to the stanchion 13 (in other words, the angle of the column 2 with respect to the vertical). FIG. 9 is a cross-sectional view showing a state in which the angle at which the column is erected is adjusted with bolts. In the configuration shown in the figure, the column 2 can be moved in the X-axis direction at the position of the bolt hole 21 according to the screwing amount of the bolt 22 coaxial with the X-axis direction. On the other hand, the movement of the column 2 is restricted by a wooden frame 18 at its lower end. As a result, the inclination of the entire column 2 can be adjusted by adjusting the screwing amount of the bolt 22, and the angle of the column 2 can be easily adjusted.

Next, a method for adjusting the angle at which the column 2 is erected will be specifically described with reference to FIG. FIG. 10 is a cross-sectional view explaining a method of adjusting the angle of the column. The pair of bolts 22 that are screwed in the X-axis direction are screwed until the tips of the pair of bolts 22 come into contact with the return plate 15, as shown before adjustment in FIG. The screwing amounts D1b and D2b of the bolts 22 before adjustment are, for example, the same and correspond to the state shown in FIG. In this state column 2 is not vertical. The screwing amount D is the amount by which the bolt 22 is screwed from the outer peripheral surface of the column 2 . More specifically, the screwing amount D is the distance from the outer peripheral surface of the column 2 to the outer peripheral surface of the bounce plate 15 when the bolt 22 is screwed.

When the angle of the column 2 is adjusted, the pair of bolts 22 that are screwed in the X-axis direction, for example, are rotated in opposite directions from the state in which the tips thereof are in contact with the return plate 15 . For example, one bolt 22 on the left side of the page is rotated in a direction (clockwise) to be screwed in, and the other bolt 22 on the right side of the page is rotated in a direction (counterclockwise) to be pulled out. As a result, the screw-in amounts D1a and D2a after adjustment shown in FIG. 10 are different from each other. For example, the screwing amount D1a of the bolt 22 screwed in the positive direction of the X-axis is larger than the screwing amount D2a of the bolt 22 screwed in the negative direction of the X-axis. As a result, the column 2 moves by a predetermined amount Mx (Mx=|D1a-D1b|=|D2a-D2b|) in the negative direction of the X-axis in this cross section with the position of the stanchion 13 serving as a reference as a reference. . Therefore, as shown in FIG. 9, the column 2 is tilted by the movement of the lower end being restricted by the wooden frame 18 . As described above, the angle of the column 2 with respect to the vertical is adjusted by adjusting the screwing amount D of the bolt 22 while checking the plumb bob 23 .

Similarly, the column 2 can be arbitrarily tilted in the X-axis direction and the Y-axis direction by adjusting the screwing amount D while checking the plumb bob 23 for the bolt 22 in the Y-axis direction. The adjustment of the angle of the column 2 is finished when the angle of the column 2 is adjusted vertically by the above steps. Any procedure other than the procedure described above can be adopted as the procedure for screwing the bolt 22 . For example, one of the pair of bolts 22 may be used to incline the column 2 at an arbitrary angle, and then the opposing bolt 22 may be screwed in to fix.

The bolts 22 can be inserted in four directions if the column 2 is a square pipe having a rectangular cross section, but other configurations are possible. For example, it is also possible to adopt a configuration in which bolts 22 are pressed from three directions inclined by 180 degrees from the center of a column iron pipe having a circular cross section. In this case, the rebound plate 15 also has a circular cross section.

Subsequently, in step S6 shown in FIG. 2, the operator injects the filler 24 into the column 2. As shown in FIG. FIG. 11 is a cross-sectional view showing a state in which the column is filled with filler. In this process, the filler 24 is injected from the upper end of the column 2 as indicated by the arrow in the figure. In this step, the filler 24 is injected to a position lower than the position of the bolt 22 to fill the bottom inside of the column 2 . As the filler 24 filled in the column 2, in principle, the same concrete or mortar milk as the filler 17 filled in the stanchion 13 can be used. For this reason, redundant description of the filler 24 is omitted. As the filler 24, it is preferable to use mortar mixed with fine aggregates in consideration of filling properties in the column 2. As shown in FIG.

It is particularly preferable that the cement mixed with the fillers 17 and 24 to be injected into the column 2 and the stanchions 13 include alumina cement (early-strength cement). Alumina cement, for example, can be hardened in a short time, so that the construction period can be shortened. In addition, since alumina cement has a strong reducing power, it is possible to prevent rust-induced corrosion of metal members (in particular, the inside of the column 2) in contact with the fillers 17 and 24 for a long period of time. In addition, alumina cement has the characteristic of being non-shrinkage with extremely small shrinkage after hardening compared to other cements, so that it can prevent the occurrence of unnecessary stress in the column and stabilize the structure of the column. can be done. For this reason, alumina cement is a cement component more suitable for the column structure in this embodiment, which is configured by combining the fillers 17 and 24, the columns 2, and the stanchions 13. As shown in FIG.

However, since alumina cement is more expensive than other cements, cement other than alumina cement can be used as a hardening agent for the filler 17 when the construction cost is important. Further, for example, instead of using alumina cement as a hardening agent for the filler 17 filled in the stanchions 13, only inexpensive Portland cement is used, and alumina cement is mixed and used as a hardener for the filler 24 filled in the column 2. good too. For example, alumina cement and portland cement can be used in the filler 24 at a blending ratio of 1:3 by volume. As a result, the filler 24 can have the advantages of both alumina cement and Portland cement. In this way, it is also possible to configure the filler 17 and the filler 24 to have different cement compounding ratios. Also, the filler 24 in the column 2 and the filler 17 in the stanchion 13 can be used separately.

It should be noted that the viscosity of the filler 24 needs to be properly controlled in order to properly construct a high-strength column structure. Specifically, the slump (viscosity) of the filler 24 immediately after kneading water and cement is low enough to fill the column 2 with no gaps, and it does not leak too much from the gap between the column 2 and the foundation 1. high is preferred. In this case, cement milk with a relatively low viscosity may be used. When adjusting the viscosity of the filler 24, the viscosity of the filler 24 can be lowered by, for example, reducing the blending amount of aggregate such as sand or gravel or increasing the blending amount of water. . Conversely, the viscosity of the filler 24 can be increased by increasing the blending amount of aggregate or decreasing the blending amount of water. The generation of rust can also be prevented by reducing the amount of air (Poisson's ratio) by using a filler in the form of mortar milk.

By filling the columns 2 with such a filler 24 , the foundation 1 made of concrete and the filler 24 are integrated with the stanchions 13 and the reinforcing bars 14 erected on the foundation 1 . As a result, a structure (rigid structure) in which the column 2 is firmly connected to the foundation 1 can be obtained, and a column structure having strength equal to or greater than that of a structure in which the column 2 is buried inside the foundation can be obtained. .

In addition, when the viscosity of the filler 24 is high, the filler 24 may not be properly filled in the column 2 and the intended strength may not be obtained, or air may be included inside the filler 24 . be. In such a case, a step of applying vibration from the outside of the column 2 may be performed. According to this, the filler 24 can be filled in the column 2 (especially the lower part) by vibration, and the air in the filler 24 can be discharged.

Subsequently, the operator removes the wooden frame 18 in step S7 shown in FIG. FIG. 12 is a cross-sectional view showing a state in which the wooden frame is removed from the foundation. By removing the wooden frame 18, there is no obstacle around the column 2, and the space under the roof of the carport 100 can be efficiently used.

Subsequently, in step S8 shown in FIG. 2, the operator pulls out the bolt 22 from the column 2 after the filler 24 has hardened. In this step, the four bolts 22 are removed from the column 2, leaving only the bolt holes 21 in the column 2. As shown in FIG. As described above, since the filler 24 is filled only to a position lower than the bolt 22 in the column 2, the bolt 22 can be removed even after the filler 24 has hardened. By removing the bolt 22 in this way, the column 2 has no projections and can be made into a beautiful column. In this way, by adopting a construction method without bolts, it is possible to create a stylish pillar.

Subsequently, in step S9 shown in FIG. 2, the operator fills in the bolt holes 21 from which the bolts 22 have been removed. FIG. 13 is a cross-sectional view showing a state in which bolt holes are filled with bolts removed. Four bolt holes 21 are formed in the column 2, three of which are filled with a sealing material 25 and one bolt hole 21 is left open. A silicone-based sealant can be used as the sealing material 25 . Alternatively, the rust preventive paint may be applied after the sealing material 25 is cured.

A single bolt hole 21 that is not filled functions as a drain port for discharging moisture and the like collected in the column 2 due to dew condensation to the outside of the column 2 . As a result, it is possible to prevent the column 2 from being rusted and corroded due to accumulation of water inside the column 2 . From this point of view, it is preferable that the height at which the filler 24 is filled in the column 2 is as close as possible to the lower side of the bolt 22 . However, if the bolt 22 may be left in the column 2 , the filler 24 may be filled up to a height where the threaded portion of the bolt 22 is buried in the filler 24 .

As described above, by performing the first step S1 to the last step S9, the entire process of installing the pillar is completed. In the column installation method of this embodiment shown in the above steps, the step S3 of providing the wooden frame 18 surrounding the stanchion 13 on the foundation 1 having the stanchion 13, and the column 2 is mounted between the wooden frame 18 and the stanchion 13. and a step S5 of screwing the bolt 22 into the bolt hole 21 from the outside of the column 2 and pressing it toward the stanchion 13 to adjust the angle at which the column 2 is erected by the screwing amount of the bolt 22. Therefore, by simply adjusting the screwing amount of the bolt 22, the column 2 with an appropriate angle can be installed inexpensively and easily regardless of the construction state of the foundation 1. - 特許庁

<Description of column structure>
In this embodiment, the column structure installed by the process described above has the configuration as described above, but as a main configuration, as shown in FIG. It has as its main structure the column 2 provided and the filler 24 cured between the stanchions 13 and the column 2 . Further, in the column 2, as shown in the figure, a bolt hole 21 is formed at a position overlapping with the stanchion 13 and above the upper surface of the filler 24. As shown in FIG. As a result, in addition to the effects described above, a steel structure without bolts can be achieved, and the pillars can be stylishly designed to match the design of ordinary houses.

In addition, the base of the column 2 can be rigid due to the reinforcing steel structure containing the filler 24 . This makes it possible to reduce the number of pillars and eliminate the need for braces. In this case, for example, it is possible to easily open and close the door of the car installed in the carport 100, to secure the road for the user of the carport 100, and to make effective use of the land. can also Therefore, the added value of the carport 100 can be enhanced.

A springback plate 15 having an outer diameter larger than that of the stanchion 13 is fixed to the stanchion 13 at a position corresponding to the bolt 22 . Further, by the step S9 described above, the bolt hole 21 filled with the sealing material 25 from which the bolt 22 was removed and the open bolt hole 21 are provided, so that water can be drained from the inside of the column 2. .

<Effects of this embodiment>
As described above, according to the column installation method, carport installation method, column structure, and carport of the present embodiment, the angle (inclination) of the column 2 is adjusted by the screwing amount (screwed degree) of the bolts 22. be able to. Thus, for example, the column 2 can be installed at an appropriate angle regardless of the construction state of the foundation 1, and even if the installation position of the foundation 1 is deviated from the predetermined position, the column 2 that will be the pillar of the structure can be erected appropriately. can. In addition, since the column 2 is not buried in the foundation 1, the amount of the column 2, which is an expensive iron pipe with a large outer diameter, can be reduced, and the strength is such that it will not collapse even with snow accumulation. It is also possible to realize a high column structure at low cost. In addition, since the foundation 1 has the stanchions 13 stably erected, the columns 2 can be supported by the stanchions 13 when the carport 100 is erected, thereby preventing the columns 2 from unintentionally overturning. be able to. As a result, it is possible to improve the safety of the construction work, which is the stage before erecting the structure, and also to reduce the difficulty of the construction work.

In addition, according to this embodiment, the columns can be installed in a simple process as described above. It is possible to provide a construction method that can be constructed by learning.

Further, according to this embodiment, by injecting the filler 24 from the upper end of the column 2, the portion below the upper surface of the filler 24 can have a structure with extremely high strength, and the column 2 can be secured at this portion. No more buckling. This eliminates the possibility of buckling only in the column 2 in the upper part of the filler 24, so that the more the filler 24 is filled, the stronger the structure can be. When the length of the column 2 used in the carport 100 is about 3 m, the length of the stanchion 13 on the foundation 1 is set to about 1 m and the filler 24 is filled (the filling height of the filler 24 is, for example, about 1/3 of the height of the column 2), sufficient strength can be obtained. In addition, since the filler 24 is filled in the bottom of the column 2, it is possible to prevent the column 2 from being twisted or pulled up. In addition, the filler 24 containing alumina cement can prevent rust inside the root and increase the strength of the column 2 . Further, by forming a reinforcing bar structure extending from the foundation 1 to the upper part, it is possible to prevent the filler 24 filled inside from being crushed even when the column 2 described later is subjected to an impact.

Further, according to this embodiment, in a normal steel frame structure, the portion between the column 2 buried inside the foundation 1 and its upper side (in other words, the upper surface of the foundation 1) is rusted and corroded, and the column 2 is broken. The column 2 can be maintained at a high strength without being put away.

<<Second embodiment>>
FIG. 14 is a perspective view showing a carport in the second embodiment. In addition, illustration of the foundation 1 is abbreviate|omitted in the carport 101 in the same figure. Also, in the same figure, the components denoted by the same reference numerals as those of the above-described embodiment have the same functions unless there is additional explanation. The carport 101 is the same as the first embodiment in terms of the structure and installation method of the pillars, but by flattening the upper surface of the roof plate 4 and providing a handrail 5 around the outer periphery of the roof plate 4, the user of the carport 101 can has made it possible to use the top of the roof as a veranda. Further, a staircase 6 is provided on the side of the carport 101 to connect the top of the roof plate 4 and the ground. By setting it as such a carport 101, the space which can be used on the roof of the carport 101 can be provided. In such a case, not only the load of the shingle 4 but also the non-uniform load caused by the movement of the user on the roof is applied to the column 2 . However, by adopting the high-strength column structure described above, it is possible to prevent the columns 2 from buckling or the like. In such a configuration, braces (not shown) or the like may be provided to further increase the strength. Moreover, like the carport 101, another function may be provided on the roof plate 4, and a solar panel may be mounted to provide a carport having a photovoltaic power generation function.

<<Modification>>
Further, in the above-described embodiment, the structure on the foundation 1 was described as a structure that supports the roof plate 4 only with four pillars (columns 2) and beams 3. The present invention can also be implemented in a structure in which strength is ensured by inserting braces. Further, the present invention may be implemented in a heavy steel frame structure using a thick iron column having a thickness of 6 mm or more, or may be implemented in a light steel frame structure using a thin iron column having a thickness of less than 6 mm. good. It should be noted that the present invention can also be implemented by using other metal structural members instead of the iron structural members in the above-described embodiment. For example, the present invention can be implemented even in a structure using structural members such as aluminum columns and stanchions.

In the above-described embodiment, the springboard 15 and the stanchion 13 are configured separately, and the configuration example in which the springboard 15 is fixed to the stanchion 13 has been described. may be

Further, in the above-described embodiment, the configuration using the springback plate 15 whose external dimensions increase stepwise has been described, but a configuration in which a plurality of members are combined as shown in FIG. The springboard 15 shown in the figure comprises four fluctuation stabilizing plates 151 , four fixing plates 152 , eight fasteners 153 and one square pipe 154 .

The fluctuation stabilizing plate 151 is a metal angle member having an L-shaped cross section. One side of the fluctuation stabilizing plate 151 is fixed to the side surface of the stanchion 13 with four bolts 16 . The fluctuation stabilizing plate 151 is bent perpendicularly to one side and supports the fixed plate 152 and the square pipe 154 on the other side extending laterally in FIG. The fluctuation stabilizing plate 151 is provided with long holes (not shown) on each side. The fluctuation stabilizing plate 151 is fixed to an arbitrary position in the height direction by inserting a bolt 16 into an elongated hole provided on one side and fixing it to the stanchion 13 .

The fixing plate 152 is a metal angle member having an L-shaped cross section. One side of the fixed plate 152 is fixed to the other side of the fluctuation stabilizing plate 151 with fasteners (for example, bolts and nuts) 153 . The position of the square pipe 154 can be regulated from the inside by setting the other side of the fixing plate 152 upright. The square pipe 154 is an iron square pipe having an outer diameter larger than that of the stanchion 13 and smaller than that of the column 2 . The square pipe 154 corresponds to a cylindrical member of the springboard 15 against which the bolt 22 is pressed. The square pipe 154 is fixedly supported with respect to the stanchion 13 by being supported by the fluctuation stabilizing plate 151 and the fixed plate 152 from the lower end and the inner peripheral surface. By assembling these members in the order described, the springboard 15 (square pipe 154 ) can be fixed to the stanchion 13 .

With the configuration as described above, the rebound plate 15 includes a rectangular cylindrical portion arranged on the outside, four connecting portions extending inward from each side of the rectangular cylindrical portion, and bending and extending from the connecting portions at right angles. and four fixing portions fixed to the stanchions 13 . As a result, the springback plate 15 forms a pair of U-shaped cross sections that sandwich the stanchions 13 in the BB cross section of FIG. According to such a configuration, it is possible to realize the bounce plate 15 at low cost by combining simple configurations. In addition, it is easy to install because it has a structure in which the members are divided. Also, the position of fixing to the stanchion 13 and the position of attaching the fixing plate 152 can be adjusted by the long hole of the fluctuation stabilizing plate 151 . Thereby, the position where the square pipe 154 is fixed can also be freely adjusted.

In the above-described embodiment, a configuration example in which the stanchions 13 are installed at an angle close to vertical has been described. Increasing the angle may prevent the column 2 from slipping out of the foundation 1 .

Further, in the above-described embodiment, a configuration example in which one bolt 22 is provided on each side surface of the column 2 has been described, but a plurality of bolts 22 may be provided side by side on each side surface of the column 2 in the plane direction. In this case, it is possible to adjust the position of the column 2 in the rotational direction about the axial direction (vertical direction).

Further, in the above-described embodiment, an example of the configuration of a carport using the column structure according to the present invention has been described, but the column structure according to the present invention can also be applied to other structures such as solar power generation facilities and temporary housing. can also be applied. In this case, the pillar installation may be completed without filling the filler 24 with the reference frame corresponding to the wooden frame 18, which is the position reference of the column 2, fixed. As a result, the bolt 22 and the reference frame may be left as they are and used temporarily. For example, when removing a temporarily installed structure such as a photovoltaic power generation facility or temporary housing, the column 2 can be removed by removing the bolt 22 so that the structure can be dismantled.

In the above-described embodiment, the wooden frame 18 surrounding the outer side of the column 2 is fixed to the foundation 1 by the bolts 19, but the reference frame may be of other constructions or materials. For example, the frame of reference may be provided inside the column 2 . Further, instead of the wooden frame 18, a configuration may be adopted in which unevenness corresponding to the cross-sectional shape of the column 2 is provided on the upper surface of the footing upper portion 11 as a reference frame. In this case, the column 2 is installed in accordance with the reference frame regardless of the position of the stanchion 13 in step S4 described above.

For example, the footing upper portion 11 may be provided with a groove having the same cross-sectional shape as the column 2, and the lower end of the column 2 may be inserted into the groove to restrict the movement of the lower end position of the column 2. Further, a projection may be provided on the footing upper part 11 along the outside of the outer peripheral surface of the column 2 so that the movement of the lower end position of the column 2 is restricted by the projection outside the column 2 . In this case, by denting the footing upper part 11 according to the shape of the column 2 so that the protrusion surrounds the outer periphery of the column 2, it is possible to prevent the filler 24 injected into the column 2 from leaking out. can. Further, the reference frame does not necessarily need to be provided so as to be in contact with the foundation 1, and any configuration that restricts the movement of the lower end position of the column 2 at a position on the foundation 1 away from the foundation 1 can be adopted.

The pillar installation method, carport installation method, pillar structure, and carport of the present invention enable pillars at appropriate angles to be installed inexpensively and easily regardless of the construction state of the foundation, and provide a high-strength carport. The object is to install such a structure at a low cost.
