Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete panel for construction of floor surfaces such as sidewalks, roofs and building floors.

[0002]

2. Description of the Related Art When a large number of concrete panels are laid on a construction surface to form a wide floor area and the concrete panels are connected to each other, a connecting tool is projected from the side surface of the concrete panel as a connecting means. However, the connecting tool interferes with the adjacent panels, making it difficult to lay the panels in close contact with each other, resulting in an excessive gap between the panels. Also, for example, as shown in Japanese Utility Model Publication No. 57-57153,
When the sheet-like connecting pieces are attached to one side or two sides of the concrete panel so as to be joined to the lower surface of the concrete panel, the connecting work from the upper surface side of the concrete panel becomes difficult, and the work becomes difficult. However, there is a drawback in that the construction period and the construction cost are increased.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
When a large number of panels are laid to form an outdoor or indoor floor surface, there is an existing gap between the panels due to the presence of a connecting tool, which makes it difficult to closely lay the panels, and after laying the panels. The problem that the work from the panel upper surface becomes difficult is effectively solved, and the panels can be closely laid, and the connection work from the panel upper surface can be easily performed after the laying.

[0004]

[Means for Solving the Problems] As a means for solving the above problems, the present invention provides a concrete panel for floor surface construction in which a large number of sheets are laid on a construction surface to form a floor surface. A notch is provided at the edge of the concrete panel, and a hook or ring formed by bending a bar integral with the concrete panel is arranged in the notch, and a part of the hook or ring is cut from the side surface of the concrete panel. And project the hook or ring protrusions adjacent to each other.
To each other in the notches of the panel, and by mutually introducing the hooks or rings, the hooks or rings are vertically overlapped in the adjacent notches, and the overlapping forms a connection hole that opens in the vertical direction. The concrete panels are connected to each other by fastening with fasteners using holes.

[0005]

Since the present invention is constructed as described above, the concrete
While laying the panel closely, it is possible to introduce some of the rings or hooks arranged in each notch into the other notches and overlap them to connect them, and the joints are adjacent to each other as in the past. It is possible to solve the problem that it interferes with the concrete panels to create an excessive gap between the panels, and in addition, after laying the concrete panels closely, they are superposed on each other in the adjacent notches. Using the above-mentioned rings or hooks that form vertical connection holes, the connection work can be easily done from the top surface side of the panel, which allows close mounting of each concrete panel while significantly simplifying the connection work, greatly reducing the construction period and cost. Can be reduced to

Embodiments of the present invention will be described below with reference to FIGS.

The concrete panel 1 has vertical and horizontal joints 2.
Is divided into a large number of small blocks 3 by the weak joints 4 at the bottom of the joint 2, and the weak joints 4 are cracked by applying a walking load, for example. It is constructed so that it can be laid in a good manner. In the weak joint portion 4, even after the weak joint portion 4 is cracked by, for example, extending the joint body 5 such as a net material embedded in the whole concrete panel 1, The small blocks 3 are connected to each other.

A notch 6 is provided at the edge of the concrete panel 1, and a hook or ring 7 (or a hook) integrated with the concrete panel 1 is arranged in the notch 6, and a part of the ring 7 is provided. The recesses 6 of the adjacent concrete panels 1 are projected so as to be introduced into the notches 6 and are coupled to each other.

For example, as shown in FIG. 7, the hook or ring 7 is formed by bending both ends of one rod into a hook or ring shape, and a connecting rod portion 8 for connecting both hooks or rings 7 is formed. As shown in FIGS. 1 and 4, the concrete panel 1 is horizontally installed in the joint 2, and the mortar 9 or the like filled in the joint 2 is integrated with the concrete panel 1, and hooks or rings at both ends are provided. 7 is disposed in the notch 6, and a part of the hook or ring 7 is projected from the side surface of the concrete panel 1, that is, the notch 6, and the protruding portion is adjacent to the concrete panel as shown in FIG. 1 notch 6
They are introduced into each other, and both are vertically overlapped in both notches 6 and 6.

In the concrete panel 1, the notches 6 and 6 are in close contact with each other to form a mounting hole 12, and the hooks or rings 7 and 7 are vertically overlapped in the mounting hole 12. As shown in FIG. 6, using the connection hole 10 formed by the superposition and opened in the vertical direction,
Connection is made using fasteners such as bolts and nuts 11. Preferably, about half of the hook or ring 7 is projected laterally from the notch 6 so as to form a connecting hole 10 which is complementarily opened in the vertical direction when superposed.

In addition to the above-mentioned bolts, press-fitting pins, crimping tacks, and the like can be used as the fasteners.

In the above embodiment, the concrete panel 1 is defined by the joints 2 into a plurality of small blocks 3. However, the concrete panel 1 is a panel having no joints or a joint having a simple pattern finish. It can also be implemented in a concrete panel having the above.

[0013]

Since the present invention is constructed as described above, while laying concrete panels closely, part of hooks or rings made of rods arranged in each notch part is mutually notched. It is possible to introduce it into the inside and superimpose it and to use it to connect, and it is possible to eliminate the problem that the joint interferes with the adjacent concrete panels and creates an excessive gap between the panels, as in the past. Each concrete
After laying the panel closely, use hooks or rings that overlap vertically in the adjacent notches to form a connection hole that opens in the vertical direction, making it easy to perform fastening work with fasteners from the top side of the panel. In addition, it is possible to closely construct each concrete panel while significantly simplifying the connecting work, and to significantly reduce the construction period and cost.

Further, since the hook or ring has a structure in which the rod is simply bent and used for fastening, the structure can be simplified and the overall panel cost can be reduced.
