Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving frame applied to form an inverted U-shaped groove block called a so-called VS groove.

[0002]

2. Description of the Related Art Conventionally, a receiving frame has been used as a receiving material when a groove cover (grating) made of steel material is placed on the opening of a concrete groove block, and is integrated with concrete forming the groove block. It is designed to be embedded in.

As shown in FIG. 1, an inverted U-shaped groove block 1
In 00, the receiving frame 10 must be provided along the left and right edges of the block body with the opening for mounting the groove lid 20 formed in the center of the upper portion. Conventionally, in order to manufacture such an inverted U-shaped groove block 100, a corner angle 11 which constitutes the receiving frame 10 manufactured separately on the left and right sides.
Was prepared, each corner angle 11 was turned upside down, fixed to the bottom mold by bolts and nuts so as not to move, and concrete was poured into the mold.

In manufacturing such a conventional inverted U-shaped groove block, there were the following problems. In other words, when tightening bolts and nuts on the mold with each corner angle being upside down, the mold must be floated and the work is dangerous, and it takes time to tighten the bolts, which requires time and effort. There was a problem.
Also, since the corner angle is narrow, it is not stable, and is easily displaced by the placing pressure when pouring concrete, so the groove lid mounting surface is not horizontal, and the mounting width for mounting the groove lid is There was a problem that problems such as not being secured occur.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to easily and quickly set a groove block to reduce the manufacturing time. The present invention aims to provide a groove block receiving frame that can be set in a stable state and prevent misalignment, and further provide a groove block receiving frame that can also have a frame strength. It is a thing.

[0006]

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the invention according to claim 1 "is a receiving frame integrated with concrete forming a groove block, on which a groove lid is placed. Corner angles arranged on both sides with a mounting width, having a length corresponding to the above-mentioned mounting width,
The content thereof is "a groove block receiving frame characterized by being connected by a connecting member buried in concrete to form a groove block".

The invention according to claim 2 has as its contents the "groove block receiving frame according to claim 1 in which the connecting member is made of deformed round bar steel".

[0008]

In the groove block receiving frame according to the first aspect of the present invention, the corner angles provided on both sides with a mounting width for mounting the groove lid have a length corresponding to the mounting width. The groove block can be manufactured by setting the mold as it is and fixing it, and pouring the concrete into the groove block because of the structure in which the groove blocks are connected to each other by the connecting member buried in the concrete to form the groove block. That is, since the corner angles are connected to each other by the connecting member, the side edges of the corner angles can be fixed to the mold by simply pressing the side edges from several places with nails,
There is no need to float and fix the formwork, moreover, the corner angles are stable due to the connection by the connecting member,
The groove lid mounting surface can be made horizontal and the mounting width for mounting the groove lid can be secured without displacement due to the pouring pressure when pouring concrete. In addition, the connecting member has a structure in which it is buried in concrete forming a groove block, and this connecting member functions as a reinforcing bar that maintains the strength of the structure of the groove block. It makes it possible to fabricate a groove block provided at the same time.

When the deformed round bar steel is used as the connecting member as described in claim 2, the jointing property with the concrete is good and the skeleton strength of the groove block can be increased.

[0010]

Embodiments of the receiving frame according to the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the receiving frame 10 is provided with four corner bars 11 made of deformed round bar steel, in which a corner angle 11 having a groove lid mounting portion 12 is arranged with a mounting width for mounting the groove lid. They are connected by the connecting member 13. The connection between the corner angle 11 and the connecting member 13 is made by welding, and the end surface 13a of the connecting member 13 whose end is bent and formed is joined to the back surface of the corner angle 11. The corner angle 11 is made of a steel material, and the surface thereof is subjected to antirust treatment such as hot dip galvanizing. Anchor members 14 are attached to appropriate positions on the back surface of the corner angle 11. The bolt 15 attached to the groove lid mounting portion 12 is for attaching the groove lid. The receiving frame 10 shown in this example has a length direction of about 200c.
The width m is 52 cm.

As the connecting member 13 for connecting the corner angles 11 to each other, in addition to deformed round bar steel, ordinary square bar steel or round bar steel can be used, and a plate shape such as an L-shaped section, a T-shaped section or a flat plate can be used. The steel material may be appropriately cut and bent before use. Further, the connection between the corner angle 11 and the connection member 13 may be performed by welding or by tightening with a bolt or a nut. The connection member 13 is provided at an appropriate position in consideration of a structure in which the entire receiving frame 10 is not deformed, the strength of the connection member 13 itself, and the strength of the frame of the groove block 100, and the like, and is set at four positions in the embodiment. .

When a groove block is manufactured using such a receiving frame 10, as shown in FIG.
0 is turned upside down and set in the mold 40 and fixed.
In this case, the corner angles 11 are connected to each other by the connecting member 13.
The side edges of the corner angle 11 can be fixed to the mold 40 by the claws 41 that press the corner edges 11 from above. The groove block 100 can be manufactured by pouring concrete into the mold 40, solidifying it, and then removing the mold 40.

The groove block 100 thus completed
As shown in FIGS. 5 to 7, the receiving frame 10 is integrated with concrete, and the mounting portion 12 of the corner angle 11 is
The groove lid 20 is attached to the groove lid 20 by a nut 30 screwed to the bolt 15 (FIG. 1). Frame 1
0 connecting member 13 is embedded in concrete,
As a result, the frame strength of the groove block 100, particularly the strength of the concrete wall above the passage, is reinforced.

[0014]

As described above, according to the present invention,
With the above configuration, it is possible to safely manufacture the groove block, and it is possible to provide a receiving frame capable of shortening the manufacturing time, and it is possible to manufacture the groove block having the core strength at the same time. Have the effect.
