Description

The present invention relates to a deck plate positioning device that prevents a deck plate placed on a beam from shifting position during construction.

For example, as disclosed in Patent Document 1, a deck plate fastener is known in which a clamping piece that clamps the end of the deck plate inserted into the gap in the vertical direction, a locking piece that locks onto the underside of the flange, and a connecting piece that connects the clamping piece and the locking piece are made of a single piece of steel.

Patent No. 6710422

However, in the deck plate fastener of Patent Document 1, the locking piece is located below the flange of the beam, so it was necessary to either insert the deck plate from the side of the beam, or insert the deck plate fastener into the deck plate to a position where the locking piece does not come into contact with the beam flange, and then slide the deck plate fastener so that the locking piece is located on the underside of the flange with the deck plate placed on the beam.

The present invention aims to provide a deck plate positioning tool that can more easily achieve deck plate positioning.

The present invention is a deck plate positioning tool that positions a deck plate with respect to a beam having a flange portion extending laterally when the end of the deck plate is placed on the beam, and is characterized in that it comprises an attachment portion that engages with the end of the deck plate, and an elastic pressure contact portion that protrudes downward from the attachment portion when the attachment portion is engaged with the deck plate and is elastically deformable in the lateral direction but not in the up-down direction perpendicular to the lateral direction, and that, when the end of the deck plate is placed on the beam, the elastic pressure contact portion elastically deforms in the lateral direction and elastically contacts the tip of the flange portion.

In this configuration, from the time when the deck plate positioning tool is attached to the deck plate until the deck plate is placed on the beam and construction is completed, there is no need to change the position or orientation of the deck plate positioning tool relative to the deck plate, and the deck plate can be prevented from shifting position relative to the beam in accordance with conventional construction methods. Furthermore, since the elastic pressure contact portion elastically contacts the flange portion from the lateral direction, even if it becomes necessary to remove the laid deck plate from the beam, it can be removed by pulling up the deck plate against the elastic force of the elastic pressure contact portion.

The present invention also provides a deck plate positioning tool that positions a deck plate with respect to a beam having a flange portion extending laterally when the end of the deck plate is placed on the beam, and when the deck plate is pressed between the beams from above and the end of the deck plate is placed on the beam in a state where it is attached to the deck plate, the deck plate is positioned with respect to the beam, and includes an attachment portion that engages with the end of the deck plate, a base portion that protrudes downward from the attachment portion when the attachment portion is engaged with the deck plate, and a base portion that protrudes downward from the attachment portion when the attachment portion is engaged with the deck plate. and an elastic pressure contact portion that protrudes upward from the lower end of the base in a direction away from the center of the deck plate using the base as a reference, and that is elastically deformable in the lateral direction but not in the up-down direction perpendicular to the lateral direction, and the elastic pressure contact portion abuts against the tip of the flange portion and elastically deforms in the lateral direction when the deck plate is pressed into the beams from above, and is released from the elastically deformed state when the end of the deck plate is placed on the beam and the flange portion is positioned between the attachment portion and the tip of the elastic pressure contact portion.

Even with this configuration, there is no need to change the position or orientation of the deck plate positioning tool relative to the deck plate from when the deck plate is attached to the deck plate until the deck plate is placed on the beam and construction is completed, and the deck plate can be prevented from shifting position relative to the beam in accordance with conventional construction methods. Furthermore, in the construction completed state, the flange portion is positioned between the attachment portion and the tip of the elastic pressure contact portion, which has the advantage of making it difficult for the deck plate to come off the beam, improving safety.

The present invention has the excellent effect of preventing the deck plate from shifting out of position with a simple installation procedure.

Below, we will explain in detail the examples of the deck plate positioning tool of the present invention. Note that the present invention is not limited to the examples shown below, and the design can be modified as appropriate.

Example 1
For example, as shown in Fig. 4, in a steel frame structure, a deck plate 70 is placed on H-shaped steel beams 60, and then concrete 80 is poured onto the deck plate 70 to form a floor section that separates the upper and lower floors. The H-shaped steel beams 60 are preferably of a general configuration and have flanges 61 that protrude laterally.

On the other hand, the deck plate positioning tool 1 according to the present invention is formed by bending a metal plate material into a predetermined shape, as shown in FIG. 1 etc. Specifically, an attachment part 10 that is bent into a U-shape in side view is disposed at the top position of the deck plate positioning tool 1. This attachment part 10 has the function of attaching to the deck plate 70 by clamping the end of the deck plate 70 from above and below.

The deck plate positioning device 1 also includes an elastic pressure contact portion 20 that protrudes downward from the attachment portion 10 when the attachment portion 10 is attached to the deck plate 70 and is bent into an L-shape in side view.

The elastic pressure contact portion 20 is elastically deformable in the lateral direction based on its shape, but is relatively unable to elastically deform in the vertical direction perpendicular to the lateral direction.

Next, the use of the deck plate positioning tool 1 will be described.
As shown in FIG. 4 , in the completed construction state in which the deck plate 70 is placed on the H-shaped steel beams 60 , the deck plate positioning fixtures 1 are attached to both ends of the deck plate 70 by the attachment portions 10 .

As a specific procedure, as shown in Figure 2, first one end of the deck plate 70 is placed on the H-shaped steel 60, and then the other end of the deck plate 70 is placed on the H-shaped steel 60. At this time, as shown in Figure 3, the elastic pressure contact portion 20 abuts against the tip of the flange portion 61 of the H-shaped steel 60 and elastically deforms, while the deck plate 70 is lowered and pressed between the H-shaped steel 60.

When the deck plate 70 is completely placed on the H-beam 60, as shown in Figure 4, the elastic pressure contact portion 20 is maintained in elastic contact with the end of the flange portion 61 along the direction in which the flange portion 61 is extended (horizontal direction).

As a result, the elastic pressure contact portions 20 of the pair of deck plate positioning devices 1 are respectively engaged with the pair of H-shaped steel bars 60, restricting the movement of the deck plate 70 in the direction intersecting the H-shaped steel bars 60 and preventing misalignment.

By the way, if it is necessary to remove the deck plate 70 placed on the H-beam 60, the deck plate 70 can be removed from the H-beam 60 by pulling up the deck plate 70 against the elastic force of the elastic pressure contact portion 20.

Example 2
Next, a configuration of the embodiment 2 will be described. Note that the description of the same configuration as that of the embodiment 1 will be simplified or omitted.

The deck plate positioning device 2 is formed by bending a metal plate material into a predetermined shape, as shown in Figure 5 etc.

Specifically, it has an attachment part 30 that is bent into a U-shape when viewed from the side, and this attachment part 30 has the function of attaching to the deck plate 70 by sandwiching the end of the deck plate 70 from above and below.

A base 40 is provided from the attachment portion 30, which protrudes downward when the attachment portion 30 is attached to the deck plate 70.

Furthermore, an elastic pressure contact portion 50 is provided at the lower end of the base 40, which protrudes diagonally upward when the attachment portion 30 is attached to the deck plate 70. The elastic pressure contact portion 50 protrudes in a direction away from the center of the deck plate 70 when in use.

Next, the usage state will be described.
As shown in FIG. 8 , with the deck plate positioning fixture 2 attached to both ends of the deck plate 70 by the attachment portions 30 , the deck plate 70 is placed on the H-beam 60 .

More specifically, as shown in FIG. 6, first, one end of the deck plate 70 is placed on the H-shaped steel 60. Then, the other end of the deck plate 70 is placed on the H-shaped steel 60.

At this time, as shown in FIG. 7, the deck plate 70 is lowered while the base 40 and the elastic pressure contact portion 50 are elastically deformed along the projection direction (horizontal direction) of the flange portion 61 of the H-shaped steel 60, and the deck plate 70 is pressed between the pair of H-shaped steels 60.

When the deck plate 70 is completely placed on the H-beam 60, the elastic pressure contact portion 50 is released from its elastic contact state, and the flange portion 61 is positioned in the gap between the attachment portion 30 and the tip of the elastic pressure contact portion 50, as shown in Figure 8.

In this state, the deck plate 70 is attached between a pair of H-shaped steel bars 60 by the bases 40 of a pair of deck plate positioning fixtures 2, preventing misalignment.

In the configuration of Example 2, the flange portion 61 of the H-beam 60 is disposed between the attachment portion 30 of the deck plate positioning device 2 and the elastic pressure contact portion 50, and is sandwiched in the vertical direction, which has the advantage that the deck plate 70 is less likely to come off the H-beam 60. In addition, the elastic deformation of the elastic pressure contact portion 50 is maintained in a released state, which has the advantage that problems with metal fatigue are less likely to occur.

In the above-mentioned Examples 1 and 2, the dimensions and shapes of each part can be freely selected as appropriate.

In addition, in Example 2, the shape of the elastic pressure contact portion 50 is not particularly limited, and may be, for example, a shape including a curved portion as shown in FIG. 9(a), or a shape including multiple stepped portions as shown in FIG. 9(b).
