〔Example〕

Hereinafter, the present invention will be described more specifically on the basis of the embodiments shown in the drawings.

First Embodiment Here, FIG. 1 is a perspective view of a mold for forming an anticorrosion coating material, and FIG. 2 is a sectional view of a form for forming an anticorrosion coating material.

The ultra-lightweight connecting block 1 is formed by coating the anti-corrosion coating material 3 on the entire outer surface of the ultra-light weight material 2. The anti-corrosion coating material 3 is formed by using the anti-corrosion coating material forming frame 4. Done.

The anticorrosion coating material forming frame 4 has a box shape in an assembled state, and its four side surfaces are closed by the frame, but the upper side is open. The anticorrosion coating material forming mold 4 is composed of a pair of side molds 4a, 4b which are divided into two parts on the left and right with a diagonal line as the center. The side molds 4a and 4b are formed in a point-symmetrical shape.

The pair of side molds 4a, 4b has an L-shaped cross section in a plan view, and a connecting fitting 1a provided on the upper part of the super lightweight connecting block 1 so as to project laterally. A plurality of holes 4c for inserting the holes are formed in the horizontal direction. This hole
4c shows that when the pair of side molds 4a and 4b are connected and coupled, the connecting metal fitting 1a protruding laterally from the side surface of the ultra-lightweight connecting block 1 comes into contact with the inner surfaces of the respective side molds 4a and 4b. Side formwork 4
It avoids obstructing the assembly connection of a and 4b, and fulfills the function of smoothly performing the assembly connection.

Horizontal stiffeners 4d are provided outside the pair of side molds 4a, 4b, respectively. The horizontal stiffening member 4d is horizontally provided in upper and lower two stages at the outer middle part and lower end of the pair of side formwork 4a, 4b. The horizontal stiffening member 4d enhances the rigidity of the pair of side molds 4a, 4b in the width direction and suppresses deformation.

Vertical connecting plates 4e are formed at both ends of each side form 4a, 4b. Each vertical connecting plate 4e is tightened by a tightening tool (not shown) or the like in a state where its inner surface is in close contact with the corresponding vertical connecting plate 4e, so that the side molds 4a and 4b are integrally connected. Therefore, each vertical connecting plate 4e is formed with connecting holes 4f in the vertical direction at predetermined intervals, and the tightening tool is inserted into the connecting holes 4f for tightening and connecting.

FIG. 5 is a partially cutaway perspective view of the ultra-lightweight connecting block.

In the figure, an ultra-lightweight connecting block 1 has a rectangular parallelepiped shape, and an ultra-lightweight material 2 made of expanded polystyrene having a density of 0.02 or more is arranged inside. Super lightweight material 2
Has a rectangular parallelepiped shape similar to the ultralight connecting block 1, and the entire outer surface of the ultralight material 2 consisting of six surfaces is completely covered with the anticorrosion covering 3. Therefore, the ultralight material 2 is prevented from being corroded by the anticorrosion coating material 3.

As the anticorrosion coating material 3, a cement mixture material such as mortar having an anticorrosion function is used. Mortar also includes foamable ones, that is, foamed mortar. Further, in the anticorrosion coating material 3, for example, a reinforcing bar or a wire mesh is arranged as the reinforcing material 3a.

When the reinforcing material 3a is a reinforcing bar, the reinforcing bars are arranged vertically and horizontally.
The reinforcing material 3a has the functions of increasing the strength of the anticorrosion coating material 3 and enhancing the adhesiveness of the mortar. The sizes of the reinforcing bars and wire mesh used, the bar arrangement pitch, and the like are determined in consideration of the external force acting on the anticorrosion coating material 3 and the adhesiveness of the mortar.

The ultra-lightweight connecting block 1 has the ultra-lightweight material 2 arranged inside,
The anticorrosion coating material 3 is arranged on the outer surface of the ultralight material 2 so that the overall density of the ultralight weight connecting block 1 is always 1 or less, usually 0.5 as a whole. The relationship between the volume and the density of the anticorrosion coating material 3 is taken into consideration.

Next, a method of using the anticorrosion coating material forming mold based on the configuration of the first embodiment to form the anticorrosion coating material will be described below.

First, the anticorrosion coating material forming frame 4 whose four side surfaces are covered and whose top surface is opened is assembled. The anticorrosion coating material forming mold 4 is composed of a pair of side molds 4a, 4b. The vertical connecting plates 4e of the side molds 4a, 4b are brought into close contact with each other, and then a fastening tool is attached to the connecting hole 4f. Insert and tighten. This allows the side formwork 4a and 4b
Are integrally connected, and the mold 4 for forming the anticorrosion coating material is assembled. The assembly work is very easy.

Immediately before and after the assembling of the anticorrosion coating material forming frame 4, a reinforcing material 3a made of, for example, a reinforcing bar or a wire mesh is provided on six sides of the ultralight material 2 made of expanded polystyrene having a density of 0.02 or more. When the reinforcing material 3a is made of reinforcing bar, the reinforcing bar is arranged in the vertical and horizontal directions. The vertical and horizontal bar arrangement pitch of the reinforcing bars is the size of the ultra-light material 2, the strength of the external force acting on the ultra-light connecting block 1 installed locally, the thickness of the anticorrosion coating material 3, and the adhesion of mortar. It is determined in consideration of sex and the like. In addition, the size of the wire mesh when the wire mesh is used as the reinforcing material 3a is also determined in consideration of the same points. The reinforcing material 3a may be omitted if necessary.

Then, the ultra-lightweight material 2 provided with the reinforcing material 3a is inserted from the open upper surface and put inside the assembled anticorrosion coating material forming frame 4.

When inserting the ultralight material 2 into the anticorrosion coating material forming frame 4, the gap between the side surface of the ultralight material 2 and the inner surface of the anticorrosion coating material forming frame 4 is set to the outer surface of the ultralight material 2. Insert it while paying attention so that it is almost equal in all areas. Then, after inserting the ultralight material 2 into the anticorrosion coating material forming frame 4, the liquid cement mixture as the anticorrosion coating material 3 is filled from the open upper surface of the anticorrosion coating material forming frame 4.

When the cement mixture is filled, the formation of the anticorrosion coating material is performed while taking into consideration that the gap between the side surface of the ultralight material 2 and the inner surface of the anticorrosion coating material forming frame 4 is completely filled with the cement mixture material. The cement mixture is filled in the casting mold 4. After the filling of the cement mixed material is completed, the surface of the cement mixed material on the open upper surface side of the anticorrosion coating material forming frame 4 is finished with a trowel or the like into a uniform flat surface. In this case, as the thickness of the cement mixed material, the density of the whole super lightweight connecting block 1 coated with the cement mixed material is about 0.5 as a standard. For example, the cement mixture has a thickness of about 5 cm to 10 cm.

Then, the cement admixture is cured for a certain period of time, and after the cement admixture hardens to reach a predetermined strength, disassembly of the anticorrosion coating material forming frame 4 is started. Dismantling with side form 4a
After loosening all the tightening tools inserted in the connecting holes 4f of the vertical connecting plate 4e which assembles and connects the 4b, they are removed.

As a result, the combined state of the side molds 4a and 4b is released, and the side molds 4a and 4b are easily removed by simply moving the side molds 4a and 4b outward. It will be very easy. In this way, the super-lightweight connecting block 1 whose outer side is completely covered with the anticorrosion coating material 3 is manufactured.

-Second Embodiment- Fig. 3 is a perspective view of a mold for forming an anticorrosion coating material, and Fig. 4 is a cross-sectional view of a frame for forming an anticorrosion coating material.

In the second embodiment, unlike the structure of the first embodiment, the bottom mold 5 is arranged at the bottom of the corrosion-resistant coating material forming mold 4, and the corrosion-resistant coating material forming mold 4 has a pair of Side formwork 4
It is composed of a, 4b and the bottom formwork 5. That is, the anticorrosion coating material forming frame 4 is closed on the four side surfaces and the bottom surface, and only the top surface is open. And each side formwork 4
The a and 4b and the bottom mold 5 are integrally joined together.

That is, the horizontal stiffener 4d at the lower end of each side mold 4a, 4b and the connecting hole 5a at the edge of the bottom mold 5 that is in close contact with the horizontal stiffener 4d.
The bottom mold 5 and the side molds 4a and 4b are easily integrated by inserting and tightening a tightening tool (not shown) into the connecting hole 5a.

Further, four moving wheels 5b made of casters, for example, are provided on the lower surface of the bottom mold 5, so that the corrosion-resistant coating material forming mold 4 can be easily moved.

Since the configuration other than the above is the same as the configuration of the first embodiment, the same portions are designated by the same reference numerals and the description thereof will be omitted.

In addition, the method of forming the anticorrosion coating material using the anticorrosion coating material forming frame based on the configuration of the second embodiment is the same as the first method.
The description is omitted because it is substantially the same as the case based on the configuration of the embodiment.

It should be noted that this invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the spirit of this invention.
