Description

  The present invention relates to a concrete placement formwork in which a plurality of floors of a small-scale reinforced concrete building on a lower floor are simultaneously finished, and concrete can be poured continuously over a plurality of floors. The concrete inner and outer heat insulating walls can be constructed by using the concrete placement form and the heat insulating material. The concrete casting formwork becomes the base drum edge for finishing the wall. In addition, construction work was facilitated by taking advantage of the characteristics of grooving of the concrete casting formwork. Shortened construction period, reduced construction costs, and improved quality through concrete placement formwork and concrete insulation wall construction method that enabled continuous injection of concrete on multiple floors. This makes it possible to reduce industrial waste.

Regardless of the size of conventional reinforced concrete buildings, each floor has a formwork, and concrete is poured into it. Since the process is repeated, it takes a lot of work and labor, and most of the concrete injection formwork is veneer formwork and is assembled on site using auxiliary bars. The formwork is dismantled after pouring concrete and solidifying and drying, finished with nails, cleaned, and stored in a warehouse for reuse. The surface of the dismantled outer wall has various finishes such as concrete expelling, concrete expelling, ground spraying, and tiled. In addition, the present situation is that the interior and exterior finishes are made by assembling the base body frame to stretch the interior and exterior materials on the concrete surface. The torso frame is attached while adjusting the packing using concrete bonds and concrete nails. Most of them are very childish and unreliable. In addition, a heat insulating material is partly used as a mold to prevent dew condensation of concrete and internal heat insulation. However, despite the need for external insulation, there is a variety of finishes, and what seems to be this has not been developed. Next, it is well known that the problems in concrete buildings are condensation and heat insulation, and deterioration and cracking of the concrete surface. In the case of a concrete building, the sash installation is very complicated, and a sash installation opening is provided in the concrete frame, the sash is attached and fixed by welding, and the sash is packed between the concrete and the sash and caulked around the sash. However, the installation cost of the sash and the cost of packing the plasterer are large. However, the current situation is that there is a lot of water leakage from around the sash while requiring a large amount of money. In the case of a concrete building, in order to carry out the electrical wiring, an empty piping work for electrical wiring is carried out at the same time as the formwork, and it is driven into the concrete. For this reason, wiring work and installation of outlets and switch boxes are very expensive compared to electrical wiring work in wooden buildings. Therefore, like a wooden building, a construction method that can easily attach a ready-made sash and electrical wiring work after concrete placement is strongly desired.

At present, reinforced concrete houses are the most resistant to disasters, and they are not very popular even though they can be freely designed and constructed. The reason is that, regardless of the size of the building, the complicated work process for each floor, the length of construction period, and the construction cost are high. The problems to be solved by the present invention are listed as follows: b.Continuous injection of concrete on multiple floors by simultaneously implementing the formwork of the entire building instead of the formwork and dismantling of each floor in the conventional construction method. Development of concrete casting formwork that makes it possible. B. Regardless of the size of the concrete building, the building sash is welded to the opening and troweled and is installed, but it takes a lot of work and labor. Therefore, the sash for an existing house is used to make it as simple as attaching a sash of a conventional wooden building. C) In the case of a concrete building, the rooftop can be easily used, but it must be waterproofed. The waterproof construction is unnecessary. D. Conventionally, the finishing material of the concrete outer wall is limited. The construction of the base trunk edge that can easily use many interior and exterior materials developed for wooden houses to solve this problem. Ho, the conventional electrical wiring was wired with empty pipes in the concrete, but the process was omitted, and the construction of a structure that can be used for electrical wiring work after pouring the concrete. F. The concrete building has the disadvantage that condensation, cracks and water leakage occur in the room, but the construction of the frame does not. Insulation work of concrete and concrete is important, and construction of the insulation wall is particularly demanding for external insulation. H, concrete buildings use a lot of temporary materials, so we try to reduce temporary materials and industrial waste. The present invention solves the above-described problems and makes it possible to greatly reduce the construction cost and shorten the construction period.

As a means for solving the problem, a mold groove (2) in which a plurality of grooved members (1) are combined using a small-diameter wood such as thinned wood, a separator hole ( Perforated formwork (3) provided with multiple 9), formwork with concrete injection holes (4) provided with concrete injection holes (6) for injecting concrete into part of the formwork (2), perforated Prepare a formwork (5) with a view window provided with a view window (7) that can confirm the state of concrete pouring in a part of the formwork (3). Arrange these molds properly, and fix and connect the fixed part with the stable (18), and use the auxiliary material to form the multi-story molds as separators (10), foam ties ( 11) Fix the assembly with steel pipe butter (12) and steel pipe washer (13). Then, using the groove (8), the mold is passed through the mold with the stable (18), and all the molds are finished. Therefore, concrete is injected from the concrete injection hole (6) provided in the mold. In addition, it is important to confirm the concrete injection from the viewing window provided in the mold for confirming the condition of concrete injection. At the same time, in order to reduce the jointing of concrete, measure the solidification of the concrete, continuously inject the concrete on multiple floors, disassemble the temporary material after solidification drying, each formwork becomes one piece with the concrete and a decorative mold A frame wall can be formed. Further, it is strengthened by tightening the nut (15) with a washer on the thread of the separator (10) protruding into the groove (8). The formwork is a solid base barrel edge with interior and exterior finishes, and concrete is covered with a wooden formwork, so that a ready-made house sash can be easily attached and the construction work is facilitated. By applying a thin plate (19) to the groove (8) provided in the formwork, it is possible to form a painted wall ground such as diatomaceous earth indoors and outdoors, and a ground such as cloth pasting. By finishing, the groove (8) becomes a vent and becomes a protective air layer for the finishing material and the formwork, and at the same time, it becomes a wiring duct for electrical wiring and the like. Since wood has a low thermal conductivity, the concrete placement form forms a light insulation wall inside and outside. By adding a heat insulating material (20) to the concrete surface of the outer wall formwork, it is possible to construct an outer heat insulating wall that can cope with cold regions. As described above, the present invention solves the problems and makes it possible to greatly reduce the construction cost and shorten the construction period.

The present invention was developed on the assumption of a small-scale reinforced concrete building on the lower floors. It is possible to construct a frame that does not have joints. By not providing concrete joints, it is possible to construct a frame that does not require waterproofing work such as a rooftop, prevent water leakage from the joints, and eliminate the need for joint caulking. Since the formwork is a concrete casting formwork, it becomes a protective material for concrete. Since the formwork is made of wood and has low thermal conductivity, it becomes a light insulation wall indoors and outdoors by being integrated with concrete. In addition, an external heat insulation wall that can cope with cold regions can be constructed by adding a heat insulating material to the concrete surface of the external formwork and stretching it. The concrete casting formwork becomes a solid foundation rim by integrating with concrete, and many interior and exterior materials available on the market can be selected and used. Easy to use and install the sash. If the interior and exterior finishes are made by providing a groove in the mold, the groove becomes a ventilation hole, and it becomes a protective ventilation hole for the mold and the finishing material, thereby enhancing the heat insulation effect. Since electrical wiring can be performed using the upper groove, the electrical wiring work becomes very easy. Placing the formwork will prevent deterioration of the concrete surface and protect the concrete. By using a concrete casting formwork, it is not necessary to dismantle the formwork, squeeze, finish nail, transport, storage, etc., and reduce industrial waste. The concrete curing period is shortened, complicated processes are not required, and no special engineers are required. The concrete casting formwork is strengthened by solidification, and the vertical steel pipe butter is not required and the temporary material is greatly reduced. As described above, the present invention facilitates construction work, and enables shortening of construction period, reduction of construction cost, improvement of quality, and reduction of industrial waste.

These molds are processed in a factory and assembled and fixed at the site. After finishing all the molds on multiple floors, concrete (14) is injected from the concrete injection holes (6). In addition, it is important to check the concrete (14) injection status while checking through the observation window (7), and at the same time measure the solidification of the concrete (14) in order to reduce the number of concrete (14) joints. Continuous injection of concrete (14) from multiple floors. If the temporary material is dismantled after solidification and drying, each mold will become a decorative panel wall integrated with concrete (14). The concrete casting formwork provides a strong base body edge for the finishing material, allowing a wide variety of indoor and outdoor wall finishes. By finishing, the groove forms an air layer and enhances the working efficiency of the electrical wiring duct and the like. The grooved member (1) not only constitutes a mold, but can be used for various purposes such as a partition material.
