Description

Hollow unit block formwork device for civil engineering and building wall construction that is easy to assemble and disassemble {structure of concrete wall support form for construction with easy assembling and dissembling}

The present invention relates to a hollow unit block-shaped form for building concrete walls that is similar to Lego, an assembly block, and is easy to assemble and disassemble, and can be spread out and stored flat. More specifically, it relates to the assembly of forms for constructing civil engineering or architectural walls. Installation, separation and disassembly are easy and simple to assemble, similar to Lego blocks for leisure. When not in use, the form is spread out flat for stacking and storage. When in use, it is assembled in the shape of a hollow unit block, so space required and manpower for management are reduced. It is easy to reuse and move, reducing construction time and costs, and is very eco-friendly because industrial by-products or waste materials that must be disposed of are used in civil engineering and construction sites. A hollow unit block form for civil engineering and building wall construction that is easy to assemble and disassemble. It's about devices.

Currently, concrete structures are used in most general architectural and civil engineering works, and the process of installing molds that correspond to the design drawings of civil engineering and buildings, then pouring (pouring) fluid liquid concrete between the molds and curing (drying) them. A concrete facility (structure) with a solidified structure is constructed, and when the curing of the concrete is completed, the formwork is removed or demolded to expose the concrete exterior.

The formwork for conventional concrete structures (facilities) used plywood, etc., and these plywood formworks were often broken during the demolding process after one use, making them difficult to reuse, resulting in high construction costs and time. This problem was to be improved. A lot of research and development is underway for this purpose.

In order for the poured and cured concrete to achieve the designed structural shape, skilled technicians spend a lot of time and money to assemble and install the form, and once the curing of the poured concrete is completed, it takes a lot of time to demold or separate the form. It was expensive and there were many difficulties in storing, moving, and managing the non-standardized form materials.

A conventional technology that partially solves these problems is ‘Prefabricated formwork for column construction’, which is provided by Korean Patent Registration No. 10-0662018 (December 20, 2006).

Figure 1 is a structural diagram of a prefabricated form for building construction according to an embodiment of the prior art.

Hereinafter, the prior art will be described in detail with reference to the attached drawings. In the form, reinforced concrete block plates 12 and 12', which include a plurality of reinforcing bars, are inserted into each other to form a closed cylindrical form, and each reinforced concrete block plate (12, 12') is tied (bound) with a band, and if you want to demold it, release the band.

The reinforced concrete block plates (12, 12') form first locking portions (14) on both sides, and are connected to the left and right adjacent reinforced concrete block plates (12, 12') by the first locking portion (14). It is coupled to the vertically adjacent reinforced concrete block plates (12, 12') by means of second locking portions (16, 16'). The uneven portion 22 functions by increasing bonding strength with the poured concrete.

The formwork according to the prior art has a structure that cannot be repeatedly reused, and is made of reinforced concrete, so it increases in size and volume and becomes heavy, so dedicated equipment must be used for movement and management, and installation of the formwork requires a relatively large amount of labor and time. Problems such as this are still not resolved.

Therefore, there is a need to standardize the formwork and develop a formwork structure that is easy to install and dismantle even for unskilled construction workers (non-experts), can be stored and managed in a small area, and is easy to move, thereby reducing construction costs and time.

In addition, unskilled workers or ordinary people have the same meaning and will be described selectively as appropriate to the context.

The Lego-type formwork block of the present invention has a shape and configuration similar to that of toys commonly used by children or for leisure purposes, and can be formed into the first, second, third stages, etc. using insertion protrusions formed on the lower or upper end. Next, they are joined and stacked using a fitting method, so they are stacked in multiple stages to the required height, and various types of solid materials are used as fillers to fill the empty interior to keep it strong, forming a building wall. Alternatively, the hollow interior may be left empty if necessary.

It is quite natural that any one or more than one selected from waste materials, industrial by-products, concrete, or soil can be used as the filler, and additional reinforcing bars can be used as needed.

Meanwhile, industrial by-products or waste materials include waste plastics, waste fibers, waste wood, etc., including waste PVC.

The first side portion 100 has a shape corresponding to one side of each unit block for building wall construction and has the shape of a square plate with an overall uniform thickness.

The corresponding shape is that the unit block is a formwork, so any one or more than one selected among fluid concrete or soil, waste materials or industrial by-products that can be recycled for construction, or other types of fillers is poured, filled, compacted, or filled inside the hollow. It means that in the shape expressed after curing, the intaglio and the embossing are expressed in opposition or correspondence, and since they are applied in the same manner below, repeated explanations will be omitted.

At this time, rebar can be selectively inserted and installed as needed, and the filler may not be filled into the hollow interior of the unit block. In other words, wall space for civil engineering and construction can be created in various ways.

The second side part 200 has the same thickness as the first side part 100, and one end of the first side part 100 is connected to the hinge part 800 and hinged to the front or end of the unit block. It has a shape that corresponds to the back, and is in the shape of a square plate with uniform thickness overall.

The hinge portion 800 has a structure that can be bent or unfolded from a bent state, and will be described in detail again below.

The third side part 300 has the same thickness as the first side part 100 or the second side part 200, and one end of the second side part 200 is connected to the hinge part 800 to form a hinge. It is combined and has a shape corresponding to the other side of the unit block, and is made up of a square plate shape with an overall uniform thickness, but has a corresponding or corresponding shape facing the first side portion 100.

In the following description, correspondence and correspondence have the same meaning and will be described selectively to suit the context.

The fourth side portion 400 has the same thickness as the first side portion 100, the second side portion 200, or the third side portion 300, and one end of the third side portion 300 has a hinge portion on the other end surface. It is connected to (800) and hinged, has a shape corresponding to the front or back of the unit block, and is made of a square plate shape with an overall uniform thickness, but faces the second side portion 200 and has a mutually corresponding or corresponding shape.

The first side portion 100, the third side portion 300, the second side portion 200, and the fourth side portion 400 each have the same and similar size and shape, and are each standardized to a size of a corresponding numerical value set arbitrarily, and as such. Each standardized numerical value is expanded (enlarged) or reduced to either a multiple or inverse multiple value and is also standardized. Standardization means that it is very convenient for production, consumption and maintenance, lowers manufacturing costs, and allows for a variety of applications.

The side engagement-shaped connection part 500 has the same thickness as the first side part 100, the second side part 200, the third side part 300, or the fourth side part 400, and has the other end surface of the first side part 100. One end of it is connected to the hinge part 800 and hinged and combined with the other end of the fourth side part 400 to form an overall rectangular cylinder shape, and is connected to the inner surface of the rectangular cylinder shape and is connected to the unit block. The shape of the mesh connected from the side is expressed in engraving, and the overall shape is a vertical rectangular plate. Since all generally known configurations and methods are applied to the configuration in which the combined state is maintained as the fastened state, further detailed description will be omitted.

The first lower engaging protrusion 600 is fixedly installed on the lower end surfaces of the first side part 100 and the third side part 300, respectively, and is installed on the inner surface of the rectangular cylinder shape, and is attached to the first side part 100. ), is installed on the inner surface of the square cylinder shape, and has a mesh shape engraved on the lower end of the unit block. It is formed in the shape of a horizontal rectangular plate, and the upper end of the square cylinder shape is stacked at the lower end. It is inserted into the side and installed in a vertical connection.

The second lower engaging projection portion 700 is fixedly installed on the lower end surfaces of the second side portion 200 and the fourth side portion 400, respectively, has the same thickness as the first side portion 100, and has a square cylinder shape. It is installed on the inner surface, and the mesh shape is engraved on the lower end of the unit block. It is made in the shape of a horizontal rectangular plate, but is inserted into the front or back of the upper end of the square cylinder shape, which is stacked at the lower end, so that it is connected vertically. It is installed as

The side engagement portion 500, the first lower engagement protrusion engagement portion 600, and the second lower engagement projection engagement portion 700 each have a rectangular shape, and the short side length (W1) is formed to the same value. And, the first lower engagement protrusion 600 or the second lower engagement protrusion 700 is made up of one or two or more pieces of uniform length, and when made up of two or more pieces, the width (W1) It is fixedly installed and spaced apart by a value (W1).

The first lower fitting protrusion 600 and the second lower fitting protrusion 700 have a thickness of the first side part 100 from the other end surface of the hinge connection part 810 or the second hinge inclined part 830. It is configured to be installed adjacent to each other at a distance (L1) spaced apart by 1 to 2 multiples of (D1).

When the first lower engaging projection 600 or the second lower engaging protrusion 700 is composed of two or more pieces, they are fixedly installed and spaced apart (W1) by the width (W1) value.

Due to the configuration of the first lower engagement projection (600) or the second lower engagement portion (700), the loading of unit blocks is very simple and easy for even an unskilled person to do, making it suitable for the construction or construction of civil engineering and architectural walls. It has the advantage of requiring very little cost and time, and pursuing these advantages is one of the technical ideas.

The hinge portion 800 is provided at a side cross-sectional position where the first side portion 100, the second side portion 200, the third side portion 300, the fourth side portion 400, and the side hinge-shaped connecting portion 500 are connected, respectively. Each is bent in a combined state or combined with a hinge that allows the bent state to unfold.

The hinge portion 800 includes a hinge connection portion 810, a first hinge inclined portion 820, and a second hinge inclined portion 830.

The hinge connection portion 810 has a thickness and width of 1/6 to 1/5 of the thickness D1 of the first side portion 100, with the height of the first side portion 100 being its length.

The first hinge inclined portion 820 is connected to one end face in the longitudinal direction of the hinge connecting portion 810 and forms a cross section with an inclination angle in the range of 43 to 47 degrees.

The second hinge inclined portion 830 has one end face connected to the other end face in the longitudinal direction of the hinge connection portion 810 and forms a cross section with an inclination angle in the range of 43 to 47 degrees.

Since the inclination angle value formed by the cross sections of the first hinge inclined portion 820 and the second hinge inclined portion 830 is set to any value in the range of 43 to 47 degrees, some margin is prepared to take the error into account, and the ideal It is supposed to be in the range of 45 degrees, but if the error value is larger than the allowable range when forming at 45 degrees, assembly of each unit block is very inconvenient and the shape of the constructed wall may be distorted or deformed. Therefore, it is preferable that the inclination angle formed by the cross sections of the first hinge inclined portion 820 and the second hinge inclined portion 830 is configured to form a value in the range of 43 to 47 degrees.

The through hole 900 is provided in a shape corresponding to the first side portion 100 and the third side portion 300, respectively. The through hole 900 is formed by flowing concrete flowing into one side of a rectangular cylinder with open upper and lower sides, thereby increasing the bonding force due to the connection state of each cured unit block.

The first side portion 100 and the third side portion 300 are each provided with one or more through holes 900. Meanwhile, the first side portion 100 and the third side portion 300 may not form a through hole if necessary.

The through hole 900 is formed of one or a combination of one or more of a circular through hole 910, a long through hole 920, or a square through hole 930.

In the through hole 900, reinforcing bars are inserted in the left-right or horizontal direction as needed, and when necessary, reinforcing bars are inserted in the up-down or vertical direction from the open upper or lower side of the square barrel shape to fill the inflow concrete, soil, or Because it is combined with other types of fillers, it forms reinforced concrete or various types of civil engineering or architectural walls. It is quite natural that rebar can be replaced with materials that perform the same or similar functions, and such replacement materials may be developed in the future.

The unit block of this configuration is filled with a filler material selected from soil, concrete, waste materials recycled for construction, and industrial by-products, or a mixture of one or more of them. If necessary, the hollow inside may not be filled with such filler material. there is.

Meanwhile, if necessary, the unit block may or may not be separated and dismantled from the completed wall depending on the type of filling material filled inside the hollow.

In the construction of a general architectural or civil engineering wall or retaining wall, cement mortar is applied to the top of the existing completed unit block, and then the completed existing unit block is stacked or masonry on top of the existing unit block, and then finished using cement mortar again. Or plaster it. In the case of masonry or stacking with completed existing unit blocks, a certain number of blocks had to be laid (stacked) and cured for a certain period of time before masonry was laid again, which required a lot of costs such as construction time and labor costs.

In other words, in order to masonry the completed existing unit blocks, a wall is built perpendicular to the floor of the building, and this is done using skilled masonry workers' skilled techniques and work. Mortar is applied on top of the completed existing unit blocks and masonry is repeated. It was inefficient as the work required a lot of time and labor, lengthening the construction period and increasing construction costs. Additionally, bridging work was required between the existing completed unit blocks.

The present invention has a structure similar to Lego, a block toy for children or leisure, in constructing a building wall, and consists of a unit block used as a formwork and a bottom insertion protrusion shaped part, so that an unskilled person or anyone can easily stack ( stacking, masonry), so wall construction is quick and easy, but the unit blocks used as formwork can be easily dismantled and separated into flat plates for easy storage. Additionally, in constructing building walls, the construction of the bottom fitting protrusion and mesh shape makes it easy to store. Skilled workers can easily and quickly load and install unit blocks of wall formwork, and a pattern with the same effect as blockwork is expressed without the need for separate cementing work between unit blocks. In addition, the storage area of the unit blocks, which are separate formwork, is small. The technical idea pursued is to reduce the time and cost of construction by being small and easy to move.

Industrial by-products or waste materials include waste fibers, PVC, plywood, wood, paper, leather, plastics, synthetic wood, steel, and all types of waste materials and other types that can be recycled for construction purposes, but these industrial by-products Alternatively, producing molds in an environmentally friendly manner using waste materials is one of the technical ideas pursued by the present invention. Meanwhile, industrial by-products or waste materials are explained and understood to include plant materials such as rice straw.

Meanwhile, the unit block of the Lego-type formwork is in principle poured and cured with concrete in the internal space, but if necessary, general soil, clay, wamok clay, stoneware clay, diatomaceous earth, kaolin, cosmetic clay, bentonite, pottery stone, white clay, weathered clay, and red clay are used. , all materials that can be filled, such as mortar, foam epoxy, urethane, and waste paper, can be used or used as fillers, and any one or more than one selected depending on the location, use, and purpose can be used as fillers, and civil engineering foundations and When using as a wall, if a structural structure is required, strength can be increased by additionally installing reinforcing bars or reinforcing agents containing materials that perform the same function as reinforcing bars in the up, down, left, right, and selected directions.

Bottom fitting protrusions (600, 700) are formed at the bottom of the unit block body of the formwork so as to be integrated with the body of the unit blocks stacked at the bottom, so the unit blocks are inserted and stacked inside the unit blocks located at the bottom. The top and bottom are integrated and bonded together without any gaps, so they are firmly joined without any additional adhesive construction, so anyone, including unskilled workers, can work simply, easily, and quickly. Meanwhile, on the left and right sides of the unit block, one or more or 2 to 4 openings (through holes, 900, through holes) are formed as needed so that the filling materials of the left and right blocks can be firmly bonded to each other, and industrial by-products Alternatively, it is a technology to construct civil engineering and building walls in an environmentally friendly manner using any one or more than one selected among waste plastics, waste fibers, waste wood, waste PVC, waste paper, waste leather, and other materials. .

Conventional unit blocks, which are generally manufactured and produced as rectangular parallelepipeds, are used for simple construction such as building partitions or for the construction of retaining walls for civil engineering and construction. The conventional construction method for constructing such a general wall or retaining wall is to apply cement mortar or mortar on the top of the existing unit block and re-build the existing unit block on top to build the wall to the desired height. The side of the completed wall is plastered with cement mortar. In this prior art, masonry must be laid (laminated, stacked) in a certain number of steps, then cured for a certain period of time, and then masonry must be repeated, so there still remains the problem that it takes a lot of time and requires a lot of labor costs. In this way, when masonry (stacking, stacking) existing unit blocks, a skilled worker or masonry must work in order to construct a wall perpendicular to the floor surface of the building, and cement mortar must be applied to the top of the existing unit block. Masonry work required a lot of work time and labor, and inefficiencies such as longer construction times and increased construction costs remained. However, the present invention is a unit block of a hollow Lego-type formwork, and is a hollow Lego-type unit block where one or two or more fitting protrusions are formed inside the unit block body, and the bottom fitting protrusion mesh shape is located at the lower side. It is inserted (fitted) inside the top of the , integrated and bonded without any gaps, and is firmly stacked up and down without the use of adhesives such as mortar. It is a method in which adhesion is performed on the left and right depending on the materials put into the unit block of the hollow Lego-type formwork. It is a unit block of hollow Lego-type formwork for the construction of civil engineering and architectural walls using industrial by-products or waste materials. The hollow interior can be filled with various materials as fillers, and the marketability and marketability vary depending on the type of each filler. Economic feasibility can be secured. Waste fibers, etc. from industrial by-products or waste materials were generated as industrial by-products and could not be utilized as resources and had to be disposed of at separate costs. However, industrial wastes including such waste fibers had to be used as formwork materials or fillers to reduce manufacturing production costs. It has the advantage of reducing waste and increasing eco-friendliness through resource recycling, and combining form unit blocks with high strength as they are stacked. The filling material (molding material) that fills the inside of the unit block of the hollow Lego-type mold is mortar (compressive strength of 18 MPa or more), general soil, and clay. Any one or more than one selected from wamok clay, stoneware clay, diatomaceous earth, kaolin, ileum clay, bentonite, pottery stone, white clay, weathered clay, red clay, concrete, mortar, foam epoxy, urethane, etc. is used.

The unit block structure of this form allows unskilled workers or anyone to work quickly and easily for the construction and disassembly of formwork for building concrete wall construction using the concept or structure of technological ideas such as Lego unit blocks, and it occupies a small area for form storage, making it easy to move. The construction cost of civil engineering or building wall construction is reduced, construction time is shortened, installation, maintenance and management are easy due to the standardization of unit blocks, and a hollow unit block formwork device for civil engineering and building wall construction is provided that is easy to assemble and dismantle. In addition, since waste materials or industrial by-products generated at civil engineering or construction sites are used, there is an advantage in constructing walls by carrying out civil engineering or building construction in an environmentally friendly manner.

Although the present invention has been described in detail with respect to the disclosed embodiments above, it is clear to those skilled in the art that various changes and modifications are possible within the technical scope of the present invention, and it is natural that such changes and modifications fall within the scope of the appended patent claims.
