Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to the improvement of a deck plate that is used as a type of concrete during the construction work of concrete structures, and in particular, it is concerned with the improvement of a deck plate that is used as a concrete structure when constructing a concrete structure. Regarding the deck plate with attached mounting washer.

[Technical background of the invention and its problems] Conventionally, in order to attach and support a mechanical structure to the concrete frame that makes up the walls, ceiling, etc. of a building, legs 4 are planted as shown in Figure 3. A metal mounting washer 3 is buried at the time of concrete pouring so as to be exposed on the surface of the concrete frame 6, and the exposed surface of the mounting washer 3 is used as a mounting seat for the mechanical structure.

In addition, when constructing a building using the deck plate method, as shown in Figure 4, the mounting washer 3
is installed inside the deck plate 1, concrete is poured, and after the concrete hardens, the deck plate 1 in the area where the mounting washer 3 was installed is removed to expose the surface of the mounting washer 3, and then used for service. Was. For this reason, when the deck plate method is adopted, there are many work steps on site, and since the mounting washer 3 is located inside the concrete surface by the thickness of the deck plate 1, mechanical structures cannot be attached to the mounting washer 3. When installing it, there was an inconvenience that the size and structure were unavoidably complicated.

[Purpose of the invention] This invention was made in view of the above circumstances.
The purpose is to provide a deck plate with a mounting washer that can simplify the work steps at a local factory, is easy to use as a mounting seat, and has sufficient strength.

[Summary of the invention] In order to achieve the above object, the present invention includes a deck plate, a flat plate fixed to the lower surface of the deck plate, a mounting washer attached to the lower surface of the flat plate, and a mounting washer attached to the lower surface of the flat plate. a plurality of legs planted in the washer and provided through the flat plate and the deck plate; and a large number of through holes provided in the protruding end surface of the deck plate on the side not in contact with the flat plate. We provide a deck plate with a mounting metal washer, which eliminates the work of notching the deck plate after concrete pouring, and replaces the surface of the hardware for the mechanical structure mounting seat, which has sunk into a recess, with the frame. The above purpose is achieved by exposing the outermost layer.

[Embodiment of the invention] An embodiment of the invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, a deck plate 1 is continuously bent into a U-shape, and a flat plate 2 is fixed to one side thereof, and a mounting washer 3 is attached from the flat plate 2 side.

A plurality of legs 4 planted on the mounting washer 3
is long enough to be fully buried in the concrete, and is inserted into holes provided in the flat plate 2 and the deck plate 1.

Further, a large number of through holes 5 are provided at appropriate intervals on the convex end surface of the deck plate 1 on the side not in contact with the flat plate 2.

The deck plate with mounting washer configured in this way is used as a model during building construction.
Concrete is placed with the deck plate 1 side facing inside.

FIG. 2 shows a cross-sectional view of the completed frame 6 by pouring concrete using the deck plate with mounting washer of the present invention.

Next, the effect will be explained.

The deck plate 1 supports the load during concrete pouring, but since the mounting washer 3 and its legs 4 are connected sufficiently rigidly, the reaction force of the mechanical structure attached to the mounting washer 3 is is transmitted to the concrete through the mounting washer 3 and the leg 4.

Furthermore, if there is a space that is not filled with concrete between or near the legs 4, the overall strength will be insufficient. A through hole 5 for concrete inflow is provided in the plate 1 to prevent the creation of a space, so that the supporting strength of the mounting washer 3 is sufficient.

[Effects of the invention] As described above, according to the deck plate with mounting washer of the present invention, the mounting washer can be installed on the surface of the building frame with no unevenness while using the deck plate construction method, making it easier to install mechanical structures. It is easy to use and can be manufactured and used in a factory, so there are no problems with setting the mounting washer on site, cutting out the deck plate, removing parts, etc. The construction work can be simplified, the construction process can be shortened, and construction costs can be significantly reduced.
