Description

Detailed Description Reinforced concrete structure using a split-type concrete form using a splittable spacer member, its manufacturing method, and shrink form material

Technical field

The present invention relates to a concrete form material, a concrete form, and a wall-like structure in which the concrete form and the concrete are integrated.

In this specification, the spacer member and the connecting member are synonymous. Background branch art

In recent years, in order to raise the standard of houses by making them heat-insulated and highly airtight, and to make construction easier and to significantly reduce the cost of house construction, cloth foundations for wooden houses such as the two-by-one Reinforced concrete Concrete formwork assembled with synthetic resin molded body such as synthetic resin foam to form the walls of the building, rebars arranged inside the formwork, and inside the formwork Attention has been paid to building walls made of hardened and hardened concrete, and its effects are expected to be greatly enhanced.

Combined concrete formwork of such synthetic resin molded articles is roughly classified into, for example, as described in Japanese Patent Publication No. To fix the gap between the site panel members made of synthetic resin such as foamed polystyrene and having a T-shaped groove extending from the joint end toward the center, and facing each other. A part of the spacer inserted into the site panel (such a spacer member is a tensile member because it is functionally subjected to a tensile force. (Referred to as a connecting member) to assemble to form a formwork, or, for example, as described in Japanese Unexamined Patent Application Publication No. Hei 6-3446436, to deal with the problem of an opposing hannel member. The bridging part Kyo is embedded in the honeycomb member and is integrated Some of the building components are formed by stacking the building components.

(Problems to be solved by the invention)

However, since reinforcing bars are embedded in the concrete of the building, there is also a concrete formwork that can not be formed using the members described in Japanese Patent Publication No. 6-120999> 6-3 4 6 5 3 6 Concrete formwork that can be formed using rubber elements as described in No. 6 is also an operation of arranging reinforcing bars in the specified places of one of the base members or the chair members, respectively. Is also necessary.

Here, after constructing a concrete formwork by combining or picking up panel members made of synthetic Jushu, long steel bars are inserted unless it is a formwork for a straight wall with a quiet side. Since it is difficult to do this, it is necessary to perform a work to insert a reinforcing bar once the synthetic resin Hanel member is formed and the spacer is partially mounted or the bridge member is installed in the predetermined position. .

Furthermore, when the reinforcing bar must be inserted in several stages of the raft as a single-stage honeycomb member, the mounting of the reinforcing bar and the insertion of one of the spacers must be performed at the same time. In addition, it is impossible to arrange reinforcing bars that are assembled in a grid or the like by welding, wire-stopping, etc., over the panel members of the raft teaching steps.

In this way, the stacking of the synthetic resin panel members and the mounting of the rebar must be performed alternately, and even if these are performed alternately, the panel members facing each other to form the formwork are formed. If both walls are of the same height, the arranging of the reinforcement work and the inability to arrange the pre-assembled reinforcing bars are one of the objectives of the construction cost cost town. Such a concrete structure is a major drawback in construction.

Another challenge is that the forces of opposing Haneru City W against the pressure of the raw concrete flowing into the formwork are not necessarily uniform. In addition, there is a possibility that a force is applied to move the facing panel member in parallel. In addition, even though the panel members facing each other can be arranged in parallel in many cases, since the wall edge is broken into 90, the formwork of such a portion needs to be specially manufactured. Was. Inquiry of invention

To) Material of molded body

The material of the molded article 1 is preferably foamed bolus retic, foamed polyethylene, foamed polyurethane, or the like. It is also possible to use a thick molded product made of sawdust or the like. Further, one side of the mold may be a molded article of the foam as described above, and the part following the mold may be a compact molded body. The example, when the outer wall is desired to Conch Lee DOO, inside a heat insulating material, there is a play stand such 5¾ frame is suitable _n

-I f)- U) Shape of the end of the molded body

The molded article and the 18th seam of the molded article must have no concrete. Therefore, in general, as shown in FIGS. 1 to 3 and FIGS. 11 to 13, each molded body を has a valley-shaped concave portion 51 connected to the end face 2 of one side and the opposite side. It has a continuous peak-shaped protrusion 52 in a complementary shape to the end face of the joint, and in general, in order to increase the joint force of the joint, the continuous peak-shaped protrusion 52 is many in some places on the peak. It is preferable that the valley-shaped concave portion having the prism-shaped or cylindrical-shaped one-step raised portion 53 and the continuous valley-shaped concave portion also have a polygonal-pillar-shaped or cylindrical-shaped one-step concave portion corresponding to the valley.

Figs. 11 to 13 show examples of the shapes of continuous convex and concave portions for connecting the end faces of the molded body.

H) Concrete wall manufacturing process

One of the steps of manufacturing a concrete wall using the mold of the present invention is as follows. First, the above-described concrete form material of the present invention is used to form a form part on one side having a part including one end flat part of a divided spacer member.

Next, rebars are arranged at positions that should be inside the formwork. Here, the reinforcing bars can be easily arranged from the opposite side of the formwork, and the spacer member does not hinder the arrangement of the bars.

After the rebar arrangement, while connecting the divided spacer members to each other by connecting means, the above-described concrete formwork material of the present invention is used to connect the opposite side having the other corresponding spacer member. ¾ Form a frame part.

Liquid / i is applied to the place where the concrete is struck, and it tries to spread the formwork, but the corner of the formwork as shown in Fig. 28 is weaker than the other parts and faces There are many bases that require reinforcement other than connecting the tension member mounting part 56. Therefore, as shown in Fig. 28, in order to reinforce the corner of the formwork, near the corner, the adjacent tensioning member mounting portion 5 6 outside the facing tensioning member mounting portion 5 6 In between Install tension 9. Furthermore, as shown in Fig. 28, the corners of the formwork can be avoided by deforming the corners of the formwork by hitting the concrete with the board pressed against it. In addition, in order to prevent the opposing surface of the formwork from shifting in the parallel direction, the tension member can be attached in an X-shape with respect to the neighboring tension member attachment portion 6.

Then into the completed formwork: hit concrete.

In general, the structures completed in this way, such as the foundation of the building, the reinforced concrete building, the walls and floors of the building, the reinforced concrete fence, the reinforced concrete basement, the walls of the basement, etc. However, a part of the molded body after which part or all of the molded body that forms the mold is removed, or a step that removes part or all of the molded body that forms the formwork after that, The method of making the included reinforced concrete structures should also be construed as falling within the scope of the present invention. Industrial applicability

1) Since both walls of the concrete formwork are not made, that is, only one of the walls is completed, the reinforcement can be arranged without being detached by the spacer part W that is installed. (Even though it can be strongly reinforced by pulling at the time of consolidation, the work efficiency on the work is good.

2) Depending on the method of connecting the divided spacer members, a slight gap between one wall and the other wall of the concrete formwork can be tolerated.

3) After the concrete formwork is completed, the constructed concrete wall forms an insulating material, and the spacer member also serves as a base for installing interior and exterior parts and a base for painting, and a place for fixing the base. Removal work, work to insert or attach heat insulation, and work to attach or install a mounting base for interior and exterior, a base for painting, or a fixing place for the base. It is no longer necessary, making it possible to complete the building wall very quickly and easily.

4) The integration of the heat insulating material with the concrete wall provides a high standard of airtightness and high heat insulation. Housing construction is realized at low cost.

5) Molded joint type concrete-The weak point of the formwork for mold can be reinforced, and the facing surface of the formwork can be prevented from shifting.
