A fitting plug (male) 11 and a socket (female) 12 are provided.

The plug 11 and the socket 12 have a simple shape, so that the cement can be integrally formed when the template is filled with cement to form the open channel block 10, and no additional process is required.

The plug 11 and the sleeve 12 are fixed to the opposite side of the sleeve 12 with a U-shaped or U-shaped sealing material 20. This embodiment discloses a form in which the sealing material 20 is continuously provided on the circumferential surface of the plug 11 .

As shown in FIG. 1 and FIG. 2, the present invention forms a recessed space 12a for receiving the plug 11 at a position other than the top end of the socket 12, and the plug 11 is embedded in the gap of the recessed space 12a. Limit insertion The plug 11 and the sleeve 12 are displaced up and down.

Through the inserting plug 11 and the sleeve 12 which can be fitted together, and the sealing material 20 inserted between the plug 11 and the sleeve 12, thereby forming an elastic lap joint with strong water resistance (seismic lap joint) ).

The detail elements of the open channel block 10 will be further described below.

<2> Plug

The plug 11 is a protruding lap portion that fits into the socket 12 and has a thickness smaller than the body thickness of the open channel block 10. The inner circumferential surface of the plug 11 is flush with the inner circumferential surface of the open channel block 10.

The plug 11 is not equivalent to the overall circumference of the open channel block 10, but is the overall perimeter of the open channel block 10 beyond the top of its two side walls 10b.

The plug 11 has a height slightly lower than the side wall 10b of the open channel block 10, and the top surface 11c of the plug 11 has a height difference from the top surface 10c of the side wall 10b.

The plug 11 has a structural feature that does not form a protrusion above the plug 11, and the periphery of the plug 11 can be regarded as an inverted L-shaped exposed surface of the end face of the open channel block 10.

In the embodiment disclosed in the embodiment, the plug 11 has a uniform body thickness, and the outer peripheral surface of the plug 11 is parallel to the axis of the open channel block 10, but the outer peripheral surface of the plug 11 may be a tapered surface at the front end (cone) Shaped).

<3> Sleeve

The sleeve 12 is a recessed lap joint that can be engaged with the plug 11 and has a thickness smaller than the body thickness of the open channel block 10. The outer peripheral surface of the sleeve 12 is flush with the outer peripheral surface of the open channel block 10.

The sleeve 12 is not equivalent to the overall circumference of the open channel block 10, but is the overall perimeter of the open channel block 10 beyond the top of its two side walls 10b.

The sleeve 12 has a height slightly lower than the side wall 10b of the open channel block 10.

The structural feature of the sleeve 12 is formed on the top end of the sleeve 12 above the sleeve 12 above the socket 13 for closing the accommodation space, thereby limiting the upper and lower displacements between the bottom surface 13a of the upper jaw 13 and the socket 11.

The plug 11 or the sleeve 12 is provided with a sealant 20 on one side of the facing surface, and the opposite side of the plug 11 or the sleeve 12 is substantially parallel to the axis of the block.

In the present embodiment, the inner circumferential surface of the socket 12 is substantially parallel or parallel to the axis (the fitting direction) of the open channel block 10.

It is used to limit the sealing distance between the sealant 20 and the inner peripheral surface of the sleeve 12 when the inner sleeve is fitted and displaced in the axial direction.

<4> sealing material

The sealant 20 is formed by the bottom sealant 21, the side sealant 22, and the top sealant 23 which are inserted into the opposite faces of the plug 11 and the sleeve 12, and the top sealant 23 is disposed on the top cover 13 The bottom surface or the top surface 11c of the plug 11 may be on one side of the opposite surface.

Refer to Figure 3 for further explanation. The sealing material 20 of the present embodiment is provided by a bottom sealant 21 disposed at the bottom of the plug 11 (peripheral bottom surface 11a), a side sealant 22 disposed on the side of the plug 11 (peripheral side 11b), and a plug 11 is composed of a top seal 23 of the top portion (top surface 11c), and the sealants 21 to 23 are continuously fixed to the peripheral surface of the plug 11 .

The sealant 20 is inserted into the sealing material between the plug 11 of the inner sleeve and the opposite surface of the sleeve 12. As the sealant 20, a well-known rubber sealant can be used.

In the present embodiment, the hardness of each of the sealants 21 to 23 constituting the sealant 20 is uniform, but the hardness of each portion may be uneven.

In addition, the setting time of the sealing material 20 can be embedded in advance when the open channel block 10 is formed. The sealing material 20 may be installed, and after the open channel block 10 is formed, it may be subsequently added by an adhesive or the like.

The present invention not only provides the plug material 20 on the U-shaped outer peripheral surface of the plug 11 but also the top seal 23 on the top surface 11c of the plug 11.

The top sealant 23 is provided for the reaction force obtained from the upper jaw 13 after the inner sleeve fitting plug 11 and the sleeve 12 are obtained, and the elastic force of the sealant 20 of the integral sealant 20 is not lost.

In other words, after the inner sleeve is fitted, an elastic force relationship (force force, reaction force relationship) between the top sealant 23 and the bottom sealant 21 is created.

<5>Construction method

Referring to Figure 1, the joining method of the open channel block 10 will be described. The socket 11 of the open channel block 10 (the left side) is expected to be fitted to the socket 12 of the laid (right) open channel block 10, or the opposite component is fitted, thereby sequentially connecting Open channel block 10.

As shown in FIG. 4, the plug 11 received in the sleeve 12 has a top surface 11c which is positioned through the upper opening 13 of the sleeve 12 via the top seal 23.

Therefore, the floating arch of the plug 11 can be effectively prevented, and the height difference between the adjacent open channel blocks 10 and 10 is not generated.

The invention omits the procedure of rigid connection between the adjacent open channel blocks 10, 10 by connecting metal parts or screws, nuts and the like in the conventional technical means to enhance the construction efficiency.

<6>The role of the seismic joint

The various functions of the seismic lap joint will be further explained below.

<6.1> Axis relative role

In Fig. 3, only the inner sleeve fitting plug 11 and the socket 12 are passed, and the sealing material 20 inserted in the opposing surface of the overlapping portion is elastically moved in the up, down, left, and right directions.

Through the elastic force of the sealant 20, the plug 11 is suspended inside the sleeve 12.

Therefore, the inner plug 11 can automatically align the axis of the sleeve 12, and the procedure of aligning the axis with the operator can be omitted.

<6.2> Water stop function

In Fig. 3, the top seal 23 is self-sleeve 12, and the upper jaw 13 takes a reaction force to generate an elastic force downward, and the bottom sealant 21 obtains a reaction force from the bottom surface of the sleeve 12 to generate an elastic force upward, and the side sealant 22 The reaction force is generated from the side of the sleeve 12 and the elastic force is generated laterally.

As described above, the sealing material 20 inserted in the opposite direction of the plug 11 and the sleeve 12, the sealing material 20 is equal to the overall length of the sleeve 12 due to the elastic interaction (elastic interaction). The inner peripheral surface abuts. Therefore, it can exert a good water stopping effect.

<6.3> Anti-seismic and water-stopping effect

As shown in Fig. 5(a), the inner circumferential surface of the socket 12 is a plane substantially parallel or parallel to the axis (fitting direction) of the open channel block 10.

Therefore, as shown in FIG. 5(b), even if an earthquake or the like causes the adjacent open channel blocks 10 and 10 to slide in the axial direction (the left-right direction of the drawing), the sealant 20 and the inner periphery of the sleeve 12 are formed. The distance between them will not change.

If the distance does not change, the pressure-sensitive adhesive 20 does not change its pressing force. Therefore, even if the open channel blocks 10 and 10 are displaced in the axial direction, a good sealing state can be maintained.

<6.4> Limitation of displacement

Although the open channel block 10 of the present invention has a structure with an open top, the elastic shock-resistant lap joint with strong water-stopping property can be used as a culvert, and the lap joint of the adjacent open channel blocks 10 and 10 can be fitted. The part effectively limits displacement or distortion in the up, down, left, and right directions.

<6.5> buffering effect

The sealing material 20 inserted in the opposite direction of the plug 11 and the sleeve 12 can be used as a cushioning material.

Therefore, when the adjacent open channel blocks 10 and 10 are displaced and twisted in the up, down, left, and right directions, the plug 11 and the socket 12 do not interfere with each other, so that the damage of the lap portion and the sealant 20 can be effectively prevented. damaged.

[Embodiment 2]

In the following description, the same components as those in the above-described embodiments are denoted by the same reference numerals and will not be described again.

In another embodiment disclosed in FIG. 6, the hardness of the top seal 23 is greater than the hardness of the bottom seal 21 and the side seal 22.

Compared with the top sealant 23, the bottom sealant 21 is longer. If the hardness of the sealant is equal, the inner plug 11 is caused to float.

As shown in this embodiment, the hardness of the top sealant 23 is enhanced, and the hardness of the bottom sealant 21 and the side sealant 22 is further weakened.

Specifically, the bottom sealant 21 and the top sealant 23 constituting the sealant 20 have a hardness difference to easily solve the difference in the upper drop generated between the adjacent open channel blocks 10 and 10.

The hardness of the side sealant 22 is further weakened, so that it is difficult for the side wall of the overlapping portion of the inner sleeve to be formed to have a slit toward the inner side.

[Example 3] <1> Method for preventing lateral gaps in sidewalls

As shown in FIG. 7, the open top open channel block 10 has a cantilever structure on its side wall, so that the side wall of the open channel block 10 is susceptible to a lateral gap due to the elastic force of the side sealant 22 of the sealant 20. That is, insert The side wall of the plug 11 is inclined toward the inner side, and the side wall of the socket 12 is inclined toward the outer side.

Another embodiment will be further described with reference to FIGS. 8 to 10. The end portion of the top seal 23 is compressed so that the bottom surface 13a of the top surface 13 of the closing sleeve 12 is inclined toward the inner side of the open channel block 10, thereby preventing lateral slits (tilting) of the side wall of the overlapping portion of the inner sleeve fitting.

<2> Top seal compression structure example 1

Fig. 8 discloses a state in which the bottom surface 13a of the upper cymbal 13 and the top surface 11c of the plug 11 are inclined toward the inner side of the open channel block 10.

In the embodiment disclosed in the embodiment, the angle θ _{1 of the} top surface 11c of the plug 11 (the angle of inclination toward the inner side of the open channel block) is closed, and the bottom surface 13a of the upper surface 13a of the sleeve 12 is closed at an angle θ ₂ (toward the open channel block) The inside angle is larger and the end of the top seal 23 is compressed.

Another embodiment of the embodiment shown in Figure IX, which is compared with the plug 11 of _a surface angle θ 11c (the inclination angle of the inner member toward the open channel block), the upper jaw 12 to close the mouth of the sleeve 13 the bottom surface 13a included angle θ ₂ (toward the open channel The angle inside the block) is small.

In Fig. 9, the angle θ ₁ of the top surface 11c of the plug 11 is horizontal (0°).

<3>Wedge effect of top sealant

In the form shown in FIG. 8 and FIG. 9, the angles θ ₁ and θ ₂ between the top surface 11c of the plug 11 and the bottom surface 13a of the upper jaw 13 are angularly different, and the plug 11 and the socket 12 of the top seal 23 are inserted. The space between the rooms gradually narrows toward the inside of the open channel block.

Therefore, the top seal 23 between the plug 11 and the sleeve 12 has a compressive force which gradually increases toward the end portion and hardens like a cone. That is, the hardness of the top seal 23 gradually increases toward the end.

Therefore, it is possible to effectively limit the lateral gap generated by the plug 11 and the socket 12 of the inner sleeve fitting.

The stronger the separating force between the sidewalls, the more effective it is to prevent lateral sidewalls from creating a lateral gap. The better.

Through the wedge effect of the top sealant 23, not only the anchoring action of the plug 11 but also the waterproof property is improved.

<4> Example of compression structure of top sealant 2

In the embodiment shown in Fig. 10, the angle θ ₁ of the top surface 11c of the plug 11 is equivalent to the angle θ _{2 of the} bottom surface 13a of the cymbal 13 on the closing sleeve 12, and the top surface 11c of the plug 11 and the bottom surface 13a of the upper cymbal 13 are parallel to each other. .

In the form shown in FIG. 10, the space between the plug 11 and the socket 12 in which the top seal 23 is inserted is uniform, and therefore, in general, the elastic force of the top seal 23 is uniformly applied to 11c, 13a. On the face, when the side wall is to produce a lateral gap, the top sealant 23 is integrally compressed by the plug 11 and the sleeve 12 11c, 13a on both sides thereof, so that the top seal 23 gradually hardens toward the end. Therefore, as in the above-described form, it is possible to restrict the lateral gap generated by the plug 11 and the socket 12 which are fitted by the inner sleeve.

<5>The form with poor hardness

The compression molding examples 1 and 2 of the above top seal are applied to the above-described second embodiment.

The elasticity of the top sealant 23 is greater than the elastic force of the bottom sealant 21 and the side sealant 22, thereby preventing lateral gaps in the side walls or improving the sealing effect.
