Abstract

PURPOSE:To reduce the cost of transportation by eliminating the needs to keep the storing position of formworks by a method in which a bonding section is provided on one end of a form panel plate, three rows of ruled lines are provided in parallel with the bonding section of the form panel, and the perforated form panels are assembled and set on a slope. CONSTITUTION:A bonding section 4 with an adhesive 5 coated or an adhesive tape is provided on at least one end of a water-resistant plate 1, e.g., plastic plate, corrugated cardboard, etc. Three rows of ruled lines 2 are also provided in parallel with the direction of the bonding section 4, and many holes 3 are formed between the lines 2 and the longitudinal ends or between the lines 2. the bonding sections 4 and 4' of the plates 1 are joined with each other on site to assemble a formwork with rectangular cross section of holes 3. Cement mortar is injected from the upper part of the formwork to construct a slope frame. Since the form plates can be assembled on site, the needs to keep the storing place of the form work materials can be eliminated, and the cost of transportation can be reduced.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to the construction of a framework constructed for surface preservation by folding and assembling plates made of water-resistant material to form a hollow rectangular shape with a surface-resistant shape. This relates to a pouring method that uses all formwork materials for legal frameworks that have through holes.

(Conventional Technique v#) Currently, various types of slope frame materials are used to protect nine slopes, and their cross-sectional specifications are generally larger than / □am square. If it is made of concrete, it is heavy and bulky, so it requires a large area for storage in a warehouse or the like, and there is a problem in that the transportation cost for bringing it to the site is also high.

(Problem to be solved by the invention) Therefore, since assembly on a slope requires a lot of labor, after assembling lightweight formwork materials on a slope and stacking them in stages, mortar is applied to the hollow part of the formwork. There is a method of forming a heavy slope by injecting isophotonic animals, but there is a difference between ) and frame materials, etc.
1h'p A'J k i15" bulky eve, storage.The current situation is that it has not yet reached the point where the problem has been solved or transportation costs have been reduced.

As a result of various studies on new methods that can solve the problems of the formwork materials used in the construction of conventional legal frameworks, the inventors of the present invention have found that water-resistant materials such as cowhide, cardboard, etc. A small piece of a flexible plate also has a joint for a gluing margin at one end, has three rows of score lines along the direction of the joint, and connects with the score line or the longitudinal end. A board with holes of a certain size arranged in parallel on the surface of the cabinet is assembled on site.

It was concluded that the above-mentioned problem could be solved by forming and using a formwork material having transparent holes with hollow rectangular end faces.
Achieved non-invention.

(Means to solve problem c) The configuration of the present invention will be explained below based on the drawings.

A water-resistant board such as a plastic board or cardboard having a certain thickness and length (for adhesives having an adhesive part (1) with adhesive applied or adhesive tape affixed to at least one end of the board) A joint having three rows of grooves iii! A plate body in which a large number of C3+ are arranged in parallel is assembled as shown in FIG. 2 to form a formwork material with a completely blind through hole (3) having a hollow rectangular end face shape.

The glue joint (4!l) shown in Figure 1 is not necessary, but if it is provided, when assembled as shown in Figure 2, the joint will completely cover the function of the 7 drainage lunges.Through hole β) has the function of reducing the weight of the formwork material and of squeezing out excess water from mixing the fluid by injection pressure.

The formwork materials explained above are assembled using a generally known method, and the formwork materials are inserted into all joints in a grid pattern using cross, square, T, and L+YB joints. Connect using bolts and nuts 7 and fix with anchors.

Once this assembly is completed, fluid mortar or concrete is injected from the upper part of the formwork to construct the legal frame, and the inside of the legal frame is filled with vegetation soil bags or additional soil to make it grow.
The legal frame construction method is completed.

(Effects of the Invention) As described above, the present invention comprises forming a slope by assembling and installing formwork materials having through-holes with hollow rectangular end faces in a lattice shape on a slope, and then allowing flow to flow from appropriate locations on the top. Because it is a method of constructing a legal frame by completely pouring it, it is ideal for work at high places or on steep slopes, and it is possible to form a strong legal frame that is integrated by weight.

Moreover, the weight method frames such as secondary concrete products have the function of holding down the ground by their weight, but the method structure constructed according to the present invention is lightweight, but the formwork materials with hollow rectangular holes in the end face are used to cover the slope. After assembly and installation, the fluid is pumped up and injected from the upper part into the hollow part, which dramatically improves work efficiency, and since the frame becomes heavy after injection, it is possible to use a gravimetric method frame. In the same way, a function to hold down the ground occurred, and the legal framework no longer rose due to maintenance pillars or frost heaving, and the earth retaining function of the legal framework no longer deteriorated.

Thanks to the through holes provided on each side, the excess water from the mixing water of the fluid is quickly pushed out of the formwork by the injection pressure, reducing the water pressure applied to the formwork material, which reduces the wall thickness of the formwork material. It can be made thinner and lighter, and since the water-cement ratio is lowered, the curing time is increased, resulting in a high-density, high-strength, integrated legal framework, which prevents joints from breaking and collapsing. .

Furthermore, the present invention allows for forming formwork materials by easily assembling water-resistant plates such as plastic boards and dungeons having a certain thickness and length on-site, so that they can be stored like conventional methods. This saves space and significantly reduces transportation costs.
