Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a scaffolding floor support that is hooked onto a wooden pillar in order to be used as a scaffolding support for the wooden pillar that has been erected during wooden construction work. .

(Prior art and its problems) Conventionally, in wooden construction work, the idea of using erected wooden pillars as supports for scaffolding had not occurred.

During construction, the wooden pillars of a house are the most important thing to avoid damaging, as they define the aesthetics of the completed interior. At construction sites, the current practice is to cover the surfaces of pillars with veneer or other board materials or wrap them with paper to prevent them from becoming scratched.

For this reason, when constructing a wooden house, scaffolding materials were assembled from the ground around the house, as in general construction work.

However, considering the current construction situation, such as labor shortages, resulting high wages, and increases in total construction costs due to soaring land prices, it is difficult to secure the necessary amount of scaffolding materials and to go to the site. The cost of transportation, transportation after removal, assembling and removal on site, the time and manpower required for these various operations, and the associated costs account for a considerable proportion of the total construction cost, and the client is responsible for the original cost. Moreover, it was a huge burden on construction companies, who faced severe competition.

In recent scaffolding construction, timber is no longer used; instead, a method has been adopted in which various pre-standardized round pipe materials are assembled using similarly standardized fasteners. There is.

One of these fastening parts is a ``protrusion bracket for building frames'' proposed in Utility Model Application Publication No. 49-93116.

This bracket is a frame assembled in the shape of a right triangle as a whole, and includes a horizontal member a that horizontally supports the scaffolding floor that workers step on from the bottom of the floor, and a horizontal member a that is applied to and is attached to a vertically erected support pipe. It consists of a vertical member c that is stopped, and an inclined member b that is diagonally spanned between the vertical member c and the horizontal member a to provide supplementary support to the horizontal member a.

However, this bracket cannot be used with wooden columns because of the uniqueness of the means of locking the vertical member to the column pipe, and thus its construction.

First, the locking means requires a horizontal pipe extending at right angles from the support pipe, and the bracket is suspended by hooking onto this pipe. There are no crossbars on the wooden pillars of the house. Even if present, this bracket cannot be used as it is not capable of supporting the scaffolding floor.

Second, the means for preventing swinging of the vertical member applied to the support pipe is a U-shaped portion surrounding three sides of the support pipe circumference, and a screw threaded in a direction that blocks one open side of the U-shaped portion. The tip is fixed with a pin 8 placed against the side of the support pipe. If this is used on a wooden pole, the pin will cause fatal damage to the wooden pole.

The present invention aims to solve these problems and provide a scaffolding floor support that does not have crossbars and can be used directly on wooden columns that are easily damaged.

(Means for Solving the Problem) The supporting device of the present invention includes a floor support member whose side surface near the tip touches one side of the erected wooden column and extends horizontally toward the rear end, and the wooden column. A front member extends from the floor support member to contact the front of the wooden pillar, a backing member extends from the floor support member to contact the back of the wooden pillar, and a part of the other side of the wooden pillar. It consists of a hanging piece slightly protruding from the tip of either the front member or the backing member, and the horizontal distance between the front member and the backing member is determined from the front of the wooden pole. In addition to approximately matching the length corresponding to the thickness up to the back surface, a head gap is provided in the vertical arrangement positional relationship between the front cover member and the back cover member, and the head gap is set between the front cover member and the back cover member. When the present support is tilted so that the straight line connecting the tip of the hanging piece provided on one of the supporting members and the tip of the other member not provided with the hanging piece becomes horizontal, The structure is such that the distance between the tip of the hanging piece and the tip of the other member not provided with the hanging piece is such that the support can be applied to the wooden post.

(Example) The present invention will be described below based on an example of implementation.

Reference numeral 10 in the figure indicates a floor support member. The floor support member 10 has a side surface 10A of the member near the tip.
It is applied to one side 30a of the wooden pillar 30 that has been erected.

As can be seen from FIG. 3, the floor support member 10 of this embodiment is a square timber that is elongated from the tip to the rear end, and a part 10A of the vertical side surface on the tip side of the square timber is attached to the side surface 30a of the wooden pillar 30. The square timber itself is perpendicular to the wooden pillar 30, and the rear end of the square timber is at a right angle to the wooden pillar 30.
It extends far away from the front surface 30b.

A stopper portion 11 is protruded from the rear end of the square timber, that is, the floor support member 10, to prevent the floor materials 31 placed side by side from slipping off the rear end. Further, it is preferable to apply an anti-slip member 12 such as rubber to the upper surface of the floor support member 10 on which the flooring material 31 is placed to prevent the flooring material 31 from sliding sideways.

On the tip side of the floor support member 10, an upper surface 10 of a square timber is provided.
The backing member 20 whose base is fixed to the B side is the wooden pillar 3
It extends at right angles in the horizontal and lateral directions so as to touch the back surface 30d of 0.

The backing member 20 of the embodiment is made of L-shaped steel material, and one surface 21 of the outer surface of the L shape is applied to the back surface 30d of the wooden pillar 30, and the rear end side of the other surface 22 is used for floor support. It is fixed to the upper surface 10B of the member 10.

A front support member 40 running parallel to the backing member 20 in the same direction at a constant interval,
It is fixed to the floor support member 10.

This front member 40 is also an L-shaped steel material like the backing member 20, and one surface 41 of the outer surface of the L shape
is applied to the front surface 30b of the wooden pillar 30, and the other surface 4
The rear end side of 2 is fixed to the lower surface 10C of the floor support member 10 at right angles.

A flat hanging piece 50 that is hooked onto a part of the other side surface 30c of the wooden post 30 is protruded from the tip of either the backing member 20 or the fronting member 40. .

The hanging piece 50 of the embodiment has a surface that extends from the tip of the backing member 20, more specifically, from one of the outer surfaces 21 of the backing member 20, so that the surface of the hanging piece 50 touches a part of the side surface 30c of the wooden post 30. It sticks out slightly so that it hits.

This hanging piece 50 has a support main body consisting of a floor support member 10 and a backing member 20 and a front support member 40 extending laterally in parallel from the floor support member 10 in the same direction as the wooden pillar 30. This is a stopper that functions to prevent it from shifting from one side surface 30c to the other side surface 30a. Therefore, this hanging piece 50
It is sufficient if the size is such that the main body of the support does not shift laterally when it hangs over the side surface 30c of the wooden pillar 30.

Next, the positional relationship between the front member 40 and the back member 20 will be explained.

First, the distance between the abutment members 40 and 20 in the horizontal direction is set to a width that is larger than the thickness of the wooden pillar 30 from the front side 30b to the back side 30d, that is, the width of the wooden pillar 30, but almost matches it.

The arrangement positional relationship between the front member 40 and the backing member 20 in the vertical direction is such that a vertical head gap is provided.

This drop interval is determined by the hanging piece 50 provided on either the front member 40 or the backing member 20.
When this support is tilted so that the straight line connecting the tip of the hanging piece 50 and the tip of the other member (the front member 40 in the embodiment) on which the hanging piece 50 is not provided is horizontal, the hanging piece 50 It is necessary that the distance is such that the main support can be applied to the wooden post 30 from between the tip of the support member 40 and the tip of the other member 40 where the hanging piece is not provided.

That is, the floor support 20 is tilted with respect to the vertical wooden pillar 30, and the straight line connecting the tip of the hanging piece 50 and the tip of the other member 40 where the hanging piece 50 is not provided is defined as horizontal. In such a state, the wooden pillar 30 is placed between the front member 40 and the backing member 20.
This is because it has to be inserted.

In the embodiment, the floor support member 10 is a square timber, and the vertical width of this square timber, that is, from the upper surface 10B to the lower surface 10C.
The required head distance is obtained by ensuring a sufficient thickness up to the top surface 10B and fixing the backing member 20 to the top surface 10B and bottom surface 10C, respectively.

Note that this drop interval is determined by the degree of protrusion of the hanging piece 50 provided on either the front member 40 or the backing member 20, that is, the distance from the tip of the member (40 or 20) on which the hanging piece 50 is provided. It varies greatly depending on how much the hanging piece 50 is made to protrude. Hanging piece 5
The larger the 0 protrudes, the larger the gap needs to be.

Since the support main body of this embodiment is constructed in this way, the floor support member 10 is held at an angle so that the rear end is slightly raised upward, and the backing member 20
If the line connecting the hanging piece 50 at the tip of the front cover member 40 and the front edge of the front cover member 40 is horizontal, and the wooden pole 30 is inserted between the front cover member 40 and the backing member 20 and pushed in, the wooden pole 30 can be easily removed. can be applied to.
Then, after pushing the floor support member 10 sufficiently, the rear end of the floor support member 10 is lowered to its original position, and the floor support member 10 is returned to the horizontal position to be securely fixed.

When the support body is caught in such a state,
Due to its own weight, the front member 40 is pressed against the front surface 30b of the wooden pillar 30, and the backing member 20 is pressed against the rear surface 30d of the wooden pillar 30.

This is because the front member 40 and the backing member 20 act as a stopper to prevent the rotational moment caused by the rear end side of the horizontally extending floor support member 10 from falling under its own weight. This is because the action and reaction in the lever principle are in a state of balance.

Therefore, as a result, the floor support member 10 is maintained in a horizontal state and fixed at the height position of the wooden pillar 30.

However, if the flooring materials 31 are placed side by side near the rear end of the floor support member 10 in this state, the rotational moment on the rear end side of the floor support member 10 increases due to its weight, and the rotational moment on the rear end side of the floor support member 10 increases accordingly. Since the wooden pillar 30 is sandwiched between the front member 40 and the backing member 20 more strongly and from alternate directions, the floor support member 10
will be more securely fixed.

This means that when a worker is on the floor, the fixing force is further increased.

Note that when the floor support member 10 is returned to the horizontal position after the front support member 40 and backing member 20 of the support body are fully pushed into the wooden post 30, the hanging piece 50 will be attached to the corner of the wooden post 30 in the pushing direction. Since it hangs, there is no need to worry about the support body being pushed back and falling out.

Finally, in order to remove the support body from the wooden pillar 30, after removing the flooring material 31, lightly lift the rear end side of the floor support member 10 upwards, and while keeping it in that state, pull it apart horizontally and laterally. .

In this way, the attachment of the support body to the wooden pillar,
Removal can be easily done with one hand without using any tools.

In addition, if each side of the wooden pillar 30 to which the facing member 40 and backing member 20 of the floor supporting member 10 are applied is hidden by a wall or the like when the house is completed, the As shown in FIG. 3, holes 51 may be provided in the front member 40 and the backing member 20, and a fastening member 52 such as a nail or a screw may be passed through to temporarily fasten to the wooden post 30.

However, in this case, it takes time and effort to remove the fastening member.

(Effects of the invention) Since the invention is constructed as described above, it can be easily supported at any height position for a single wooden pillar without crossbars erected at a wooden construction site. The tool body can be fixed.

Furthermore, when attaching to or removing from a wooden pole, there is no need for time-consuming fixing work such as nailing or screwing, or for removing those nails or screws.

However, with this invention, the floor support attached to the wooden pole has an unparalleled effect in that the more the load from the flooring material and workers is applied, the more the fixing effect to the wooden pole increases. This makes the scaffold extremely safe.
