Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete box type tension vertical joint groove constructed without an attachment abutment for attachment of an embedded object.

[0002]

[Prior art]

 The joint groove of the concrete precast product as a conventional cab system has an insert hole for attachment on the inner side wall of the U-shaped side groove type or BOX culvert type, where a steel or resin abutment is attached and embedded in this. Items (electric wires, telephone cables, water pipes, etc.) had been fixed.

However, these products have the following drawbacks and problems to be solved. The large number of insert holes attached to the inner side wall and the pitch of the reinforcing bar spine were inevitably complicated, and it took time and effort for manufacturing, resulting in poor efficiency.

A steel material or resin attachment that is attached as an abutment requires about 3 places for a product length of 2 m in order to prevent the embedded object from hanging down, the cost is relatively high, and it can be opened for external extraction. For products with holes, etc., I had difficulty in the complexity of their mounting positions.

Even in the vertical installation between products, since it is a side wall back joint, it is difficult to work in a narrow construction site with many buildings.

Therefore, the inventor of the product of the present invention has solved the problems to be solved by the product of the present invention as follows while engaging in the design, manufacturing, and construction of these products.

[0007]

[Problems to be solved by the invention] An assembly structure is used for products that are easy to manufacture and not complicated to construct.

[0008] The attachment abutment is not required for attaching and fixing the buried object, and the cost is reduced.

[0009] The product is such that the buried object can be easily installed and does not become disordered with other buried objects. The product will be easy to work even in a narrow space and will be earthquake resistant.

The above is the problem to be solved by the present invention, and the means for solving the problem are as follows.

[Means to be solved by the device]

 The outline frame is a concrete product, and the product vertical joint tension part is provided on the inner surface, and the embedded object is inserted or guided in the assembly hole of the concrete guide plate that can construct the assembly through hole. At the same time, the whole is tough and strong like a box.

This will be described with reference to the drawings of the embodiments.

[Example of device]

 Low concrete version 1. Through the side walls 2.2. And the side wall 2.2. At the top of the abutment 3.3. And the lid plate 1-1. Waterproof seal material that constructs a waterproof state in combination with 6.6. So that it can be attached. Low version 1. Tension material (usually a piano wire) is used on the inner surface of the key area of 5.5. Vertical through hole that can penetrate through 4.4. Is provided in two or more places, and the contour is covered with a U shape to form a BOX-shaped product.

Next, at the time of construction, the concave hole 7. Guide version 8-1 [Receiving]. 8-3 (intermediate type). 8-2 (cover type). And set this concave hole 7. Wire cable 10. Telephone cable 11. Water pipe 12. Etc. are buried and the abutment 3.3. Waterproof sealing material 6.6. Attach lid plate 1-1 (the surface may be a walking lid with an uneven pattern). Box type tension vertical joint groove formed by covering and fixing.

The product of the present invention constructed as described above has the following actions and effects.

[0015]

[Operation and effect of the device] Unlike the conventional product, there is no insert hole on the inner surface of the side wall that is built almost vertically, so the formwork is not complicated and the back bars of the reinforcing bars can be evenly spaced, and concrete can be poured. It is efficient because it does not require excessive vibration.

Since there is no attachment attached as an abutment and this part is replaced with concrete, the cost is low and the work is easy.

Since the vertical joint between products can work in the inner cavity, not only efficient and complete work can be performed, but tension can also be restored by applying tension to the joint part against a large external force such as an earthquake. There are also actions and effects.

In addition, the guide plate 8-1.8-3.8-2. Serves as a support (supporting base), and unlike the conventional products, the buried object will not be damaged by the inner wall side wall collapse.

Even if a need arises for replacement, it is sufficient to pull out the old embedding material and insert the new embedding material into the hole, and it is economical and quick and easy.
