2. Description of the Related Art In general, reinforced concrete buildings are provided with formwork facing each other, connected and reinforced with a home tie, cast concrete between the formwork, and solidify and cure. It is made by removing and finishing the surface.

[0003] However, in the above method, the mold material must be carried into the site and assembled by a large number of skilled workers. In addition, concrete must be cast, cured and then dismantled, and must be transported and stored for the next construction, requiring a large amount of manpower and a large space.

As a solution to this problem, a permanent mold which has a beautifully structured architectural plate material opposed to each other with a space between them and is fixed and cast concrete in between, and then without removing it as it is outside the building. The frame method has come to be implemented.

[0005]

[Problems to be Solved by the Invention] By the way, since it is difficult to form a permanent form for columns and beams, the surroundings of the reinforcing bars including the main bars and ribs embedded in the columns and beams as usual. While forming the form by bending, it is continuously reinforced with a home tie, cast concrete inside, cured and cured, then remove the form and finish the surface.

The inventors of the present invention have conducted various studies to carry out a permanent formwork method for columns and beams, and as a result, the extrusion of ceramic materials can be freely selected in length and any cross-sectional shape can be obtained. From this, we thought that permanent forms of columns and beams could be easily made. The present invention has been made based on the above idea, and the exterior finish is applied by attaching a permanent formwork of an extruded column or beam around the reinforcement of the column or beam and placing concrete. was, pillars, pillars beam is obtained, the beams of

FIG. 1 is a square tube showing an embodiment of a permanent form of columns and beams according to the present invention. The shape of the permanent mold is not limited to a cylinder or a polygonal cylinder as long as the permanent mold is cylindrical and has the same cross-sectional shape in any part. However, the rectangular cylinder 1 having a square cross-section will be described below as a representative example.

The rectangular tube 1 is attached to a reinforcing bar 2 composed of a main bar 2a, a rib bar 2b and the like, so that the bar 2 is composed of a plurality of parts 3 which are vertically divided. The cross section of each of the divided parts 3 has the same shape in any part, and each part 3 is formed by extrusion molding of a ceramic material.

The cross-sectional shape of each part does not need to be the same, and it is sufficient if the rectangular cylinder 1 is divided into a plurality of parts in the vertical direction. If a square tube can be formed, it is desirable that the number of parts 3 be small in terms of handling. For example, as shown in FIGS. 2 and 3, a part 3 divided into two parts is convenient.

Further, if the engaging portion 5 is formed in the divided portion (contact portion) 4 between the components as shown in FIGS. 4 and 5, the contact portion 4 of the component can be pressed. Accordingly, the lateral displacement of the contact portion is prevented, and the shape of the rectangular cylinder 1 is correctly maintained by matching the surfaces of both ends of the component.

[0014] Further, when forming a square tube by combining parts with the reinforcing bars in the middle, concrete is cast inside,
It is necessary to strengthen the combination. Therefore, as shown in FIGS. 6 and 7, the shape of the rectangular cylinder 1 is firmly held by the detachable holding tool 6, or as shown in FIG. A stopper 7 may be attached to the reinforcing bar 2 to prevent the reinforcing bar from shifting during transportation. In this case, since the component is made by extrusion molding, it is easy to form a large number of through holes 8 as shown in FIG. 9, and the base of the stopper may be attached to this through hole 8. Further, as shown in FIG. 10, a stopper 7 may be provided between the inner surfaces of the formed rectangular tube 1 and fixed to the main reinforcement 2a. In this case, a through hole may be provided in the component, and both ends of the stopper 7 may be fastened inside the through hole 8. FIG.
As shown in (1), the stopper 7 can be penetrated on both sides, but in this case, it is better to remove the stopper 7 before placing concrete. Also, when extruding the part 3,
A reinforcing wire may be buried in this for reinforcement. In this case, a rectangular tube can be formed by pulling out a part of the wire and locking the drawn-out portion to a reinforcing bar.

It is desirable that the reinforcing bar 2 is located substantially at the center of the rectangular tube 1. Therefore, as shown in FIG.
In the case where a longitudinal ridge is formed as a spacer 9 on each component and the rectangular tube 1 is arranged around the reinforcement 2, if the tip of the spacer 9 is in contact with the reinforcement 2, the reinforcement can be easily arranged. It can be located at the center of the rectangular tube, and a strong reinforced pillar is formed. In addition, the dovetail groove 10 may be formed as shown in FIG. 13 in order to firmly integrate the square tube 1 and the cast concrete. The dovetail groove 10 can be easily formed between the spacers or the like by extrusion molding even if the spacer 9 or the stopper 7 is provided.

Further, instead of the spacer 9, the function of the spacer 9 for setting the position with respect to the reinforcing bar 2 at a predetermined position by increasing the height of the ridge 10a forming the dovetail groove may be provided.

As shown in FIG. 14, the part having the ridges 9 or the ridges 10a forming the dovetail grooves 10 has
If the tip of Oa or 9 and the tip of the contact portion 4 are divided so as to be located in the same plane, when the components 3 are stacked, they are stably stacked, and the transportation and storage are facilitated.

Further, as shown in FIG. 15, a specific through hole is enlarged to be a through hole 8a for a ventilation duct, or as shown in FIG. You can also.

Further, as shown in FIGS. 17 and 18, a large number of sound absorbing holes 11 communicating from the outer surface to the through holes 8 may be formed to enhance the sound absorbing performance.

[0020]

[Effects of the Invention] As described above, the pillar according to the present invention,
Since the permanent form structure of the beam is made by combining extruded parts, the length and cross-sectional shape can be freely selected, and by attaching this to reinforcing bars, columns and beams with excellent appearance are formed Since the formwork is not removed and the removal of the formwork is not required, it is not necessary to transport the used formwork for reuse, and the space required for storage is greatly reduced. In addition, the reinforcement is arranged at a certain position from the inner surface of the hollow columnar body.
Spacer that is ridged in the length direction is integrated.
So that the tip of the spacer touches the reinforcement
In this way, the reinforcement can be easily removed from the inner surface of the hollow columnar body.
It can be positioned at a fixed position. In addition, each part
Alternatively, this is combined with a cylindrical body,
Since a stopper is provided for locking to the streaks,
With the pre-assembly of the reinforcement and the
The displacement at the time of carrying can be reliably prevented.
