Description

[Detailed explanation of the invention] (A) Technical field This invention relates to a pillar protection cover that protects the pillars of a building under construction.

When a building is under construction, materials and tools are brought in and out, and craftsmen come in and out for construction work, so there is a risk that the parts that are initially installed will become dirty or damaged during construction. Columns are also such architectural members.

(a) Prior art In the past, pillars were protected by wrapping paper around them or wrapping paper around them and tying them with rope. However, wrapping paper or straw is a labor-intensive task. Removing it is also a troublesome task.

Moreover, it is not always possible to have suitable paper or paper on hand.

In order to solve these drawbacks, the applicant
A pillar protection cover was made from a plastic extrusion molded product (Utility Application No. 58-174947, Utility Application No. 1982-82053).

It consists of a long, narrow plastic plate with a rounded curve. Both sides of the board in the width direction are folded parts that contact and press both sides of the pillar. The pillar curing cover is fixed to the pillar by pinching the pillars with both ends of the plastic plate.

When considering members that protect pillars, there is a problem that the dimensions of the pillars are not uniform.

The cross section of the pillar is square, but each side is 3 sun and 5 minutes.
There is a 5-inch one.

It is also possible to manufacture covers with different widths for each dimension, but in this case, many types of covers must be manufactured and kept in stock.

It is also inconvenient for the users, the builders, to need multiple types of pillar protection covers.

Must be versatile.

3.5 to 5 depending on one width of pillar cover
It is desired that it can be used commonly for all pillars of the size and angle.

Therefore, the above-mentioned invention attempts to solve this problem by using a highly curved elastic plastic plate.

It is a plate material with an approximately semicircular cross section. The length from end to end in a free state is 3 sun or less. If you hold both ends and spread it out, the length from end to end will be about 5 sun.

By appropriately extending the curved part, 3.5, 4,
It was also possible to fix it to a 4.5 or 5 inch square pillar.

It can be fixed to a 5 inch square pillar when the plate surface is stretched out. It can also be fixed to a 3.5 inch square pillar in a rounded shape.

Utilizing the elasticity of plastic, it could be used commonly for columns of different sizes.

It was an excellent idea.

However, since elastic force is used to accommodate differences in size, the ease of attachment and detachment differs depending on the size. For thick square columns, the ends must be pulled strongly to both sides. In the case of thin prismatic pillars, the gripping force is weak and they easily come off the pillar.

Furthermore, since they are curved in a semicircular shape, they can be transported and stored one on top of the other, but they also have the disadvantage of being somewhat bulky and inconvenient.

(c) Purpose The first purpose of this invention is to provide a highly versatile pillar protection cover that can be used in common even if the dimensions of the pillars to be protected are different.

A second object of the present invention is to provide a pillar protection cover that has a substantially constant gripping force and a substantially uniform attachment/detachment operation even if the dimensions of the pillars differ.
The third object of the present invention is to provide a pillar curing cover whose main body is substantially flat and convenient for transportation and storage.

(D) Structure The pillar protection cover of the present invention includes a flat plate portion having a sliding groove for supporting the sliding piece of the locking mechanism and a plurality of locking protrusions for locking the hook piece of the locking mechanism; It consists of a folded part formed at the end of the flat plate part and having a soft resin part to press the side surface of the column.

The locking mechanism consists of a hook piece, a rubber piece, a sliding piece, etc.

Two pillar protection covers are used in combination, and both are pulled together by a locking mechanism. Since the folded portion presses the parallel end surface of the column, the fixed position is maintained in balance with the pulling force provided by the locking mechanism.

This will be explained below with reference to the drawings.

FIG. 1 is a perspective view of a pillar protection cover 1 of the present invention. Although it is actually long and narrow, only a part of it in the longitudinal direction is shown. The cross-sectional shape of the pillar protection cover 1 is constant and can be made by plastic extrusion molding.

FIG. 2 is an enlarged end view of the pillar protection cover.

The pillar curing cover 1 has a flat and wide flat plate part 2.
and a folded part 3 continuous to this end.

On the surface of the flat plate portion 2, locking protrusions 5 to 8, 10 having an inverted L-shape in cross section and locking protrusions 9 having a T-shape in cross section are formed.

The tips of the inverted L-shaped locking protrusions 5 to 7 and 10 are directed toward the folded portion 3. These are protrusions to which the tip of the hook piece 21 of the mating locking mechanism 4 is to be locked.

However, the inverted L-shaped locking protrusion 8 and the T-shaped locking protrusion 9 constitute a sliding groove 11. Sliding groove 1
1 into which the sliding piece 23 of the locking mechanism 4 is inserted. The sliding piece 23 can move within the sliding groove 11.

FIG. 5 is an enlarged view of the vicinity of the locking protrusions 5, 6, 7, 10, etc.

FIG. 4 is an enlarged view of the vicinity of the sliding groove 11. The space surrounded by the protrusions 8 and 9 is a space through which the sliding piece 23 can pass.

The enlarged structure in the vicinity of the folded portion 3 will be explained with reference to FIG.

This part holds down the side of the pillar. It forms an acute angle to the flat plate part 2 and is continuous.

The folded portion 3 is composed of an arc-shaped curved portion 13 continuous to the flat plate portion 2, a flat connecting plate portion 14, a connecting plate portion 15, a tip portion 16, and a soft resin portion 17.

The soft resin part 17 has anti-slip grooves 18,1.
9 and 20 are carved in the longitudinal direction.

Providing the soft resin part on the back side of the folded part 3 is because
Due to the following reasons.

One is that it is non-slip.

It is the part that touches the face of the pillar, and it is soft because it must not slide against the pillar.

The other reason is to prevent the pillars from being damaged. If the part that contacts the pillar is hard, when an object hits the pillar cover, the part that contacts the pillar will move, causing damage to the side of the pillar.

The pillar curing cover 1 except for the soft resin part 17 is made of hard plastic and has appropriate rigidity.

The main part of the pillar curing cover can be formed using hard vinyl chloride resin, and the soft resin part 17 can be formed using soft vinyl chloride resin.

The end opposite to the folded portion 3 has a slightly protruding tip ridge 12.

A locking mechanism 4 that connects two pillar protection covers 1
consists of a hook piece 21, a rubber ring 22, and a sliding piece 23.

The structure of the sliding piece 23 will be explained with reference to FIGS. 7 to 10.

The sliding piece 23 is configured to be able to slide within the sliding groove 11 of the pillar protection cover 1.

7 is a front view, FIG. 8 is a right side view, FIG. 9 is a bottom view, and FIG. 10 is a sectional view taken along line XX in FIG. 7.

The sliding piece 23 is a rectangular frame body, and a vertically long rubber passage hole 24 is opened in the center. A sliding guide 25 is formed on the side of the frame and slightly protrudes toward both sides. This frame is cut in the middle.
The cutout 26 is open so that the rubber ring 22 can be inserted into the rubber passage hole 24 from here.

The sliding guide 25 is connected to the sliding groove 1 of the pillar protection cover 1.
1 from the end face.

The structure of the hook piece 21 will be explained with reference to FIGS. 11 to 14.

Figure 11 is a front view, Figure 12 is a right side view,
Figure 3 is a bottom view, Figure 14 is - in Figure 11.
FIG.

The tip of the hook piece 21 is adapted to be hooked on the locking protrusions 5, 6, 7, 9, and 10 of the opposite pillar protection cover.

A fitting tongue portion 29 is formed on the back surface of the rectangular frame body 28. This is the locking protrusion 5, 6, 7,
Insert into 9 and 10.

In the direction opposite to the fitting tongue part 29, there is a rubber through hole 3.
0 is provided in the vertical direction. Furthermore, the frame body 28
There is a wider opening 32 surrounded by. The rubber through hole 30 and the opening 32 are separated by an intermediate piece 33. A rubber ring 22 is hooked to this portion.

There is a notch 31 in the middle of the intermediate piece 33. This is necessary in order to pass the rubber ring 22 from the outside and insert it around the intermediate piece 33.

A non-slip stop 34 is formed on the side of the intermediate piece 33. This is the part that corresponds to the back side of the rubber ring 22 and prevents the rubber ring from slipping.

FIG. 15 is a sectional view of the locking mechanism 4. The sliding piece 23 and the hook piece 21 are connected by a rubber ring 22.

The sliding guide 25 of the sliding piece 23 is connected to the pillar protection cover 1
It is fitted into the sliding groove 11 from the end face. The fitting tongue part 29 of the hook piece 21 is adapted to be fitted into the locking protrusion of the mating pillar protection cover.

The rubber ring 22 is a wide band-shaped ring as shown in FIG. The reason for the wide width is to prevent the hook piece from hanging down, and to ensure sufficient strength for the rubber ring. Also, since it is wide, twisting is less likely to occur.

However, the width of the rubber ring may be narrower. It only needs to have sufficient elasticity and strength.

The sliding piece 23 and the hook piece 21 are made of, for example, ABS.
It can be made from resin.

(E) Function The mounting state of the pillar protection cover on the pillar will be explained with reference to FIG. 17.

In reality, it is long in the vertical direction, but in order to enlarge the width and thickness directions, it is shown shortened in the longitudinal direction.

An example is shown.

The width of the pillar curing cover 1 from the tip protrusion 12 to the farthest end of the curved portion 13 is 84 mm. The thickness from the top of the locking protrusions 5 to 10 to the tip 16 of the folded portion 3 is approximately 22 mm. The thickness of the flat plate part 2 itself is
It is 0.8mm.

The pillar curing cover 1 of any length can be made by plastic extrusion molding, for example,
The unit is 1700mm. This corresponds to standard column lengths.

With this size ratio, if the thickness of the pillar cover (22mm) is 1, the width will be about 4 times, and the length will be about 4 times.
That's 80 times more. Therefore, in FIG. 17, only a portion is shown in the length direction.

Two pillar protection covers 1 are used for the pillar 40 so that one side of the pillar can be covered. The pillar protection covers are turned upside down and overlapped in the front and back directions in the flat plate part 2.
Each of the folded portions 3, 3 contacts the front end of a surface of the pillar 40 that is orthogonal to the surface to be protected, and presses this surface.

Pillar protection covers overlap in the vertical direction on the flat plate part 2. The length x of the overlapping portion is from 0 to _L1 .

Here, L ₁ is the distance from the tip protrusion 12 to the locking protrusion 8. Since the sliding piece 23 enters the sliding groove 11 formed by the locking protrusions 8 and 9, the overlap of the flat plate portions 2 cannot be increased any further.

In this example L ₁ is 57mm. Further, the distance L ₀ from the tip convex strip 12 of the pillar curing cover to the surface of the soft resin portion 17 of the folded portion 3 in a free state is 77 mm.

If the width of the column is M, then the width of the overlapping part x
Since the sum of these is equal to the effective width of the two pillar protection covers, x+M=2L ₀ (1), and the range of x is 0≦x≦L ₁ (2).

Therefore, the range of the column dimension M that can be protected by this is 2L ₀ −L ₁ ≦M≦2L ₀ (3). Assuming L ₀ = 77mm and L ₁ = 57mm, M
It is sufficient if the distance is between 97mm and 154mm.

One locking mechanism 4 is attached to each column protection cover 1. Therefore, two locking mechanisms 4 can be used when joining two pillar protection covers.

In FIG. 17, two locking mechanisms 4, 4 are shown at the top and bottom. The installation direction is of course reversed. Since the locking mechanism 4 can be slid, it can be placed in any vertical position, but from the top and bottom ends of the pillar protection cover, approximately
It is appropriate to lock at the 300mm position.

The locking operation is extremely simple.

Hook piece 2 supported by rubber ring 22
1 between fingers and pull it to fit the fitting tongue part 29 into one of the mating locking protrusions 5, 6, 7, 9, and 10. This operation is performed for the upper and lower locking mechanisms 4, 4.

In this way, the two pillar protection covers are connected to each other.

There are five locking protrusions, ie, locking protrusions 5, 6, 7, 9, and 10, into which the fitting tongue portion 29 can fit. An example is shown. The distances between the locking protrusions 5, 6, 7, 9, and 10 are, for example, 15 mm, 15 mm, 19.8 mm, and 15.2 mm.

The rubber ring 22 may not have much elasticity. Since it will be inserted into the locking protrusion, it must have some elasticity. However, since there are five locking protrusions to fit into, the rubber ring does not need to stretch much.

If the pillar is thick, insert it into the locking protrusion 5.

As the pillar becomes thinner, it is preferable that the fitting tongue portion 29 is inserted into the locking protrusions 6, 7, 9, and 10 in the latter order.

In this way, there are many locking protrusions,
If the pillar is thick, there is no need to pull the rubber particularly hard. Whether the pillars are thick or thin, the difficulty of the work remains the same.

The locking protrusions 5, 6, . . . have the function of increasing the bending rigidity of the flat plate portion 2 in addition to locking the hook piece 21.

This pillar protection cover can be used not only to protect one side of the pillar, but also to protect two, three, or four sides of the pillar.

FIG. 18 is a cross-sectional plan view in case of one-sided curing (same as FIG. 17). Illustration of the locking mechanism is omitted.

FIG. 19 shows a cross-sectional plan view in the case of two-sided curing. A total of four pillar curing covers are used to cover two sides of the pillar.

They overlap at the folded portion 3, but either side may be on top. The rearmost locking protrusion 10 of the lower part catches on the back side of the upper folded part 3,
The folded portion 3 is designed not to come off easily.

Figure 20 shows an example of three-sided curing. A total of six pillar protection covers are used.

FIG. 21 shows an example of four-sided curing. A total of eight pillar protection covers are used.

(f) Effects (1) It protects the pillars during construction, so they can be prevented from getting damaged or dirty.

(2) It can be used not only for pillars, but also for curing roofs and thresholds.

(3) Two pillar curing covers of the same shape are used to protect one side. Therefore, it can be commonly used for columns of various sizes. Highly versatile.

(4) The two can be connected simply by hooking the hook piece onto the locking protrusion on the other side. Installation is easy.

(5) Since there are many locking ridges, the required force is the same whether the pillar is thin or thick. There is no difficulty in installation operation.

(6) Since there are many locking protrusions, vertical rigidity increases and straightness is easily maintained. Twisting is less likely to occur.

(7) A soft resin part is provided on the back side of the folded part.
This prevents the pillar from being damaged.
