Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a gutter block, and particularly to a joining device applied to the joint portion thereof.

(Prior Art) A bonding apparatus that has been used so far is shown in FIGS. 4 and 5.

That is, in this conventional device, a long concave notch 200 mm in width is provided on the side wall of one block body near the joint at one end, and the front wall of the long concave notch 2 and the block body are connected. A short recess about 40mm wide is made in the side wall near the other end joint of the other block body, and
A bolt hole is passed through between the front wall of the short concave notch and the abutment surface of the block body H, and the abutments of the block body A and E are joined, and then the long concave notch is A bolt is inserted from the side into the bolt holes 2 and 4, and is fastened with a nut on the side to the short recessed part to solidify the bolt as one piece.

By the way, in this conventional device, the long recessed part B for inserting the bolt is formed at a certain depth (it will break if the bolt hole D is not more than 50 mm from the outer surface of the side wall), so the internal force in this part deteriorates. invite. In addition, it becomes difficult to arrange the main reinforcing bars (reinforcing bars that are continuously buried in the side walls, bottom, and opposite wall), so it is recommended to cut the reinforcing bars and place them in upper and lower sections (Figure 6).
Reinforcement must be placed on the inside, avoiding the recessed part 2 (Fig. 7). This causes structural problems such as durability, as well as manufacturing problems such as the time and effort required to process reinforcing bars.

In order to overcome these difficulties, it may be possible to change the pitch of the main reinforcing bars or increase the wall thickness of the side walls, but in the case of the former, durability problems still remain, and in the case of the latter, New standards and cost issues will arise.

(Problems to be solved by the invention) This invention was made in view of the actual situation of conventional devices, and by holding the pipe in the shape of the long recessed part for inserting the bolt and the bolt hole, This is an attempt to solve the above-mentioned difficulties.

[Structure of the idea]

(Embodiment) To explain the embodiment shown in the drawings below, in Fig. 1, reference numeral 1 indicates one block main body 1, and the side wall near the joint at one end has a deep width notch 2a and a shallow notch 2a. A horizontal T-shaped long recess 2 consisting of a bolt insertion groove 2b is provided, and the front wall 2 of the width narrowing recess 2a is provided.
A bolt hole 4 is formed by integrally penetrating the pipe 3 between the block body 5 and the abutment surface of the block body 1, and a short recessed notch 6 is formed in the side wall near the other end joint of the other block body 5. , and the front wall 6 of the short recessed notch 6
A bolt hole 8 is formed by integrally passing a pipe 7 between the abutment surface of the block body 5 and the abutment surface of the block body 5.

Then, as shown in FIG.
After joining the abutments of and 5, bolts 9 are inserted into the bolt holes 4 and 8 from the long concave notch 2 side and fastened with nuts 10 on the short concave notch 6 side to solidify the bolts as one body. The aim is to

The above-mentioned middle pipes 3 and 7 are buried integrally during molding, but as shown separately in FIG. , to counter the tensile stress caused by fastening the bolts 9, and to prevent the pipe from detaching due to external force after construction.

[Effects of the invention] The present invention is as described above. First, since the long recessed notch 2 forms a horizontal T-shape with the deep width narrowed recess 2a and the shallow bolt insertion groove 2b, the recessed notch In addition to preventing internal force deterioration due to the provision of the main reinforcing bars as much as possible, since the bolt insertion grooves 2b of the main reinforcing bars are formed shallowly, reinforcement can be placed near the outside of the side walls without any problems (see Figures 2 and 2). Figure 3).

Since the bolts 9 are inserted into the bolt holes 4 and 8 formed by the integral penetration of the pipes 3 and 7, the side wall strength of this portion can be significantly increased.

As described above, the present invention provides a joining device that is far more advantageous in terms of strength and manufacturing than conventional devices.
