Description

A prefabricated structure of gang form for architecture}

The present invention relates to an assembly structure of a gangform for construction, and more specifically, when concrete is poured into a wall during a new construction of a high-rise apartment or a multi-storey building, a gang form (concrete form) is installed to enable continuous use by floors on the outside of the building. It is designed to improve the transport and assembly of large formwork installed outside the building when pouring, and to greatly reduce production and use costs.

In general, high-rise apartments or multi-story buildings use concrete to form the skeleton of the building.

In most conventional methods according to such concrete pouring, after installing a reinforcing bar structure to be bent to a predetermined shape, the formwork is formed to be fixed by assembling a plurality of panels on the outside of the reinforcing structure, the outside of the formwork After the scaffold is installed, the concrete is poured into the formwork.

The conventional concrete pouring method as described above requires a lot of time to form the formwork because the formwork must be manufactured using a plurality of wood panels, and since the consumed panels are mostly broken when the concrete is released, it is almost impossible to reuse them. When building a building, the cost of formwork is high and there is a problem that the work is not only inefficient because of the exterior work of the building by installing a separate scaffold, but also a high risk of a safety accident.

In order to solve the above disadvantages, a lot of efforts have been made by those in the related industry, and in recent years, form a formwork using a gang form of a metal material rather than a wooden panel.

In the above, the gangform is a formwork system that enlarges and simplifies the installation and dismantlement at once without repeating the assembly and disassembly of the member when installing the formwork. The gangform originally means all the formwork that is enlarged in a broad sense, but when classifying systemized formwork, It means only wall formwork.

When the gang foam is installed, it can be shortened due to the concrete placement on the safety scaffold when the external detection work is carried out, and the air can be shortened. It can be applied to most building structures such as apartments, large buildings, hospitals, etc., and it is particularly effective when applied to wall-type buildings.

By the way, the gangform is usually an iron plate having a predetermined area; A plurality of first reinforcing rods disposed at fixed intervals with respect to a horizontal (lateral) direction at a front portion of the iron plate and fixed to each other; A plurality of second reinforcing rods, which are arranged in pairs at a predetermined interval in the vertical (longitudinal) direction from the upper surface portion of the first reinforcing rods and fixedly installed in pairs; It consists of several 3rd reinforcement rods installed in the horizontal (vertical) direction in the upper surface part of the said 2nd reinforcement rods.

At this time, the third reinforcing rods may be provided with a square rod or the "c" shaped steel, such as the first and second reinforcing rods, the number of each reinforcing rod is approximately the second reinforcing rods> first reinforcing rods > Third reinforcing rods in this order.

The gangform of such a configuration may be assembled and used directly at the construction site, or may be manufactured in a large number of production plants and transported to the construction site as needed. In the case of the above, each part may be transported to the site to be skilled or unskilled. Because it has a form that is directly welded and assembled by not only a large amount of production is not possible, but also a lot of production and use costs, in the latter case production automation and the like can reduce the production and use costs.

At this time, the total length of either one of the horizontal or vertical lengths of each gangform (long side) is not limited, but the other one has a limited dimension (usually 4 m).

As described above, the gangforms manufactured and produced in large quantities in factories and the like are conventionally transported to a site using a lorry.

On the other hand, even in the case of a freight car having a horizontal width of about 280 cm, when the cargo mounted in its loading box protrudes from side to side, the road traffic law restricts its dimensions, and generally regulates not to exceed 30 cm on each side.

However, in the case of the gangform as described above, since the short side length is 4m, when the gangforms are mounted in a loading box of a general lorry having a width of 280 cm, the gang forms are projected by 60 cm to both sides of the loading box. In consideration of this, it will result in a further protruding 30 cm on each side, including.

Therefore, if the gangform made of finished products in the factory or the like is transported by a freight car, not only will it actually violate the road traffic law, but also the freight car will be formed in such a way that a large part of the gangform protrudes on both sides of the loading as described above. While driving, the gang form itself is damaged by hitting other vehicles or various objects, as well as other vehicles, including physical and economic damage to others, as well as the occurrence of safety accidents.

Of course, in order to prevent the above problems, in most cases, the transportation of the gang itself is carried out at night when the operation of the vehicle and the personnel are low, but it is not a fundamental solution, and in some cases, the parts are eventually transported to the construction site and are required locally. As a result of adopting the assembly and use method, the construction period is delayed and the construction cost is also increasing.

The present invention has been made to solve the conventional problems as described above, the second reinforcement welded to the first reinforcing rod to ensure that the entire length of the short side of the gangform is less than or equal to the length of the width of the cargo box of the lorry The rod is cut at a predetermined position and separated into a main body on the long side and a separate body on the short side, but a coupling jig and a third reinforcement bar are installed on the steel plate and the upper surface of the bottom of the long second reinforcing rod cutting portion on the main body side, respectively. Transport the gang form by forming a finished product by transporting it to the construction site by using a truck together with the separator, and then welding them to the joining jig by contacting the cut portions of the two reinforcing rods separated from the site. It provides an assembly structure of construction gangforms that can improve performance and assembly, as well as significantly reduce production and use costs. There is.

According to the present invention, the iron plate (1) having a predetermined area; Several first reinforcing rods (2) welded and fixed at a predetermined interval in the horizontal direction on the front surface of the iron plate (1); Several second reinforcing rods (3) welded and fixed at regular intervals in a vertical direction from the upper surface portion of the first reinforcing rods (2) in pairs; In the construction gangform consisting of several third reinforcing rods (4) welded and fixed in the horizontal direction on the upper surface portion of the second reinforcing rods (3),

A predetermined position of the second reinforcing rods 3 is cut to separate the main body 10 on the long side and the separate body 20 on the short side, but the cut portion of the long second reinforcing rod 31 on the main body 10 side. The bottom of the iron plate (1) and the upper surface portion is characterized in that the second reinforcing rod coupling jig (5) and the third reinforcing rod (4) overlap each other half and weld fixed.

At this time, the length of the second reinforcing rod 31 on the long side and the second reinforcing rod 32 on the short side has a ratio of about 3: 2, and the distance between the two pairs of second reinforcing rods 3 is equal to 1 It is made smaller than the width of the reinforcing rod (2).

In the above, the separator 20 has a form in which the second reinforcing rod 32 and the first reinforcing rod 2 on the short side are welded to each other in a lattice shape, and the second reinforcement on the long side provided in the main body 10. The rod 31 has a length equal to or shorter than the width of the load bin.

In addition, the second reinforcing rod coupling jig 5 has a configuration in which the iron plate cut to have a rectangular shape is formed to be bent in a "c" shape, and both wings have a height of second reinforcement from the upper surface of the iron plate 1. It is formed slightly lower than the height of the upper surface of the rod (3), the width is such that a portion of the two sides of the long and short side reinforcing rods 31, 32 when the abutment portion abut each other can be fitted, both wings The width of the bottom surface formed therebetween has a width in which a pair of the second reinforcing rods 3 having a predetermined distance can be sufficiently fitted.

In addition, the inner bottom edge portion of the coupling jig 5 is supported by the inner bottom edge portion of the main body 10 in a state where the cut portion of the second reinforcing rod 31 of the main body 10 is located on the center line thereof. When the (20) is coupled to the support member 51 is further provided to support the inner bottom edge portion in the state that the cut portion of the second reinforcing rod (2) of the separator 20 is located on the center line, the supporting member 51 has the same height and width as the first reinforcing rods 2.

At this time, the supporting member 51 may have a form of a square rod which is directly welded and fixed to the center of the bottom surface of the coupling jig 5 as shown in FIG. 5A, or the coupling jig 5 using a rectangular iron plate as shown in FIG. 5B. ) May be integrally bent so as to have an iron shape at the center of the bottom surface when the bend is formed in a "c" shape.

Here, reference numeral 6 is a hook that is installed to be transported to the hook of the crane when carrying and installing the gangform relatively heavy because of being made of steel.

Referring to the effect of the assembly structure of the present invention configured as described above are as follows.

First, the main technical components of the present invention is that the existing gangform made of finished products in factories, etc., because the width of the short side is much larger than the width of the loading box of the lorry, there is a transportation problem to solve this problem, In the upper surface of the first reinforcing rod (2) welded and fixed in the horizontal direction on the front side, two pairs are cut again and cut a predetermined portion (approximately 3: 2 points) of the second reinforcing rod (3) installed in the vertical direction. The main body 10 which is integrally provided with the iron plate 1, the 1st reinforcement bar 2, the 2nd long reinforcement bar 31, and the 3rd reinforcement bar 4, and the 2nd reinforcement bar 32 of the short side. ) Is to be separated into a separator (20) having a shape fixed to the first reinforcing rod (2) and a grid.

At this time, the length of the second reinforcement rod 31 on the long side of the main body 10 side which is fixedly installed on the iron plate 1 together with the first reinforcement rod 2 is equal to the width of the loading box width of the lorry. By cutting the same or smaller so that the gangform separated into two main body 10 and the separating body 20 to transport the construction gangforms using a lorry, no part is exposed to the outside of the loading box. .

On the other hand, the gangforms required at the construction site does not require a separate form as described above, but requires a finished product manufactured to a predetermined standard, so the two objects transported to the construction site in the state separated into the main body 10 and the separating body 20. Must be combined again and reduced to the finished gangform.

However, as described above, the second reinforcing rods 3 are cut into two so as to have a long and short shape, and then transported to the construction site in a state in which the second reinforcing rods 3 are separated into the main body 10 and the separator 20, and then reassembled in the field. The cut portions of the second reinforcing rods 31 and 32 may be brought into abutment with each other, and these cut portions or the periphery thereof may be welded together.

However, in the process of contacting and welding the cut portions of the second reinforcing rods, even though there is no separate mechanism, several second reinforcing rods are supported by the supporting members 51 formed on the joining jig 5 so as to be horizontal and mutual. Since the straight state is maintained, there is no bending or twisting in the vertical direction or the left and right directions, and thus welding can be easily performed, thus performing a function as a gang form.

Therefore, in the present invention, the first reinforcing rod (2) together with the iron plate (1) integrally welded to the main plate 10 side of the long side of the second reinforcing rod (31) cut section of the bottom of the iron plate (1) The second reinforcing rod coupling jig 5 having a substantially "c" shape and a supporting member 51 having a square bar or iron shape in the center of its bottom surface is formed or fixed by welding. It was.

At this time, the height of both wings of the second reinforcing rod coupling jig 5 has a height such that it does not protrude to the upper surface of the second reinforcing rod 3, the width of the second reinforcing rod of the long side and short side (31) (2) When the cutting parts were brought into contact with each other, the part was about 5 cm so that they could be fitted. In the form of interconnecting the two wing parts, the width of the bottom part to be welded and fixed on the steel plate 1 should be a certain distance. The second reinforcing rods (3) having a pair was formed to have a width enough to fit.

In addition, the supporting member 51 protruding from the bottom center of the coupling jig 5 to have the same height and width as the first reinforcing rod 2 is a cut portion of the second reinforcing rod 31 of the main body 10. The inner bottom edge part is supported by the state which is located on the center line.

On the other hand, any one of the third reinforcing rods (4) which are welded and fixed in the horizontal direction from the upper surface of the second reinforcing rods (3) for the coupling is installed to the bottom of the second reinforcing rods 31 on the main body 10 side In contrast to the jig 5, the half of the second supporting rod 31 overlaps the upper surface of the cutout portion to fix and weld the third reinforcing rod 4 and the coupling jig 5. 2 reinforcing rods 32, a portion of the cut portion is fitted to form a space that can be combined.

Therefore, when the components of the gangform (i.e., the main body 10 and the separator 20) are transported to the construction site and are assembled to a desired shape, the cutouts of the second reinforcing rods 32 of the separator 20 are assembled. A part is pushed into the space formed between the upper surface of the supporting member 51 of the coupling jig 5 and the bottom surface of the third reinforcing rod 4, and welded fixing the necessary portion.

That is, the supporting member of the joining jig 5 which is already welded and fixed on the iron plate 1 of the main body 10 so that a part of the cut-out portion of the second reinforcing rod 31 on the long side is located at the center line of the supporting member 51 ( 51) the second reinforcing rod 32 of the short side of the separator 20 which is welded and fixed in a lattice form with a space formed between the upper surface and the bottom of the third reinforcing rod 4; When the cutout portion of the) is inserted, the bottom of the cutout portion is supported by the support member 51 as shown in the enlarged view of FIG. 2 and FIG. 4, and is in contact with the cutout portion of the second reinforcing rod of the long side on the center line of the upper surface of the support member 51. The upper surface is supported by the third reinforcing rods 4 so that the long and short two second reinforcing rods 31 and 32 are in a straight line with each other to maintain a horizontal state.

Therefore, the operator is inserted into the space portion between the bottom surface of the third reinforcing rod 5 and the supporting member 51 of the coupling jig 5 as described above to maintain the state supported by the supporting member 51 and at the same time support member. Welding is integrated between the second reinforcing rods 31 and 32 and the joining jig 5 and the contact portion between the third reinforcing rods 4 on the long and short sides of which the cutting surfaces are in contact with each other on the center line. At the same time, the second reinforcing rod is welded when the cross contact portion of the first reinforcing rod 2 fixed to the bottom end of the iron plate 1 of the main body 10 and the second reinforcing rod 32 of the separator 20 is welded. (3) has the original length and at the same time the gangform of the finished product in which the main body 10 and the separator 20 are mutually coupled.

Of course, while fixing the two long and short second reinforcing rods 31 and 32 to the wing of the coupling jig 5 as described above, the contact portion with the third reinforcing rod 4 is also welded and fixed. By fixing the intersection of the first and second reinforcing rods (2) (3) by welding, the bonding force is strengthened, so that the welding parts of the cutting part can be completely prevented from being separated from each other when the gang form is used. In violation of the Road Traffic Act, etc., it may have the same functions and effects as the conventional gangforms used for transportation to construction sites.

Although the above-described embodiments are described with respect to the most preferred example of the present invention, it is not limited to the above embodiments, it is apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described above, according to the present invention, a certain position of the second reinforcing rod welded and fixed integrally to the steel plate through the first reinforcing rod is cut and separated into a main body and a separate body, so that the total length of the gangform main body is equal to the width of the loading box of the lorry. A joint jig is installed at the bottom of the long side of the second reinforcing rod cut portion of the main body that is equal to or smaller than that of the main body and is integrally welded and fixed to the steel plate. It can prevent protruding, and it is easy to carry and prevents the physical damage caused by the gangform being transported, and it is easy to use the jig for joining the cutting parts of the second reinforcing rods separated by the main body and the separating body at the construction site. Yet, it can be assembled to be in close contact with each other and completed a gang form by welding, which increases production and use costs through improved assembly. It is a very useful design, such as the width can be reduced.
