The present invention relates to a lightweight steel structure, and more particularly to a prefabricated lightweight steel structure to reduce the construction cost by constructing a combination of parts of a predetermined shape.

Conventionally, the steel structure of this kind has been used a steel structure having a relatively thick thickness. It is based on the design faithful to the principle of safety firstism, which is a design concept so far, and designed to have strength far exceeding the strength that does not cause problems such as falling or breaking in actual use. This inevitably leads to waste of materials, contrary to the concept of ultimate strength, a modern design trend.

The present invention can be applied to various types of buildings such as a single structure, for example, a horticultural crop house, a supermarket, an agricultural and fishery distribution center, a hydroponic cultivation complex, a factory, a warehouse, a club house, a lead-free car wash facility, a poultry farm, and the like.

In particular, the present invention is very suitable for factories. In other words, when the life of factory facilities tends to be shortened day by day, and when it is necessary to add large-scale new equipments, the shape of buildings may be changed accordingly. When constructed by structures and concrete, there is a problem that requires a lot of effort and expense in the dismantling and expansion. However, when the present invention is applied, each frame and frame, which are skeletons of buildings, are fixedly connected by parts and bolts and nuts of simple structures, so that they can be appropriately responded by dismantling and changing them appropriately.

Accordingly, an object of the present invention is to solve the problem in view of the conventional steel structure, and several types of assembly parts, for example, a frame, a fixed piece, a base plate, an eave and a ridge bracket, etc. forming a predetermined shape. After the first (pre-casting), and then go through the process of simply assembling it in the construction site, so that the lightweight steel structure can be completed.

In order to achieve the above object, according to the present invention, in a single structure in which a conventional anchor bolt is embedded in concrete and fixedly connected to a steel structure by an appropriate fastening means, the both sides are bent at right angles and the ends thereof are assembled. The inner side is folded again to form a rib, and the intermediate part is formed in the middle part along the long direction, and the entire body is bent in a 'L' shape, and a through hole is formed at a predetermined position, and two intermediate ribs are formed in the middle part. The fixed piece and the through hole are formed at a predetermined position, and one side is bent in a substantially 'L' shape, and both sides are connected to one side and both side base plates formed by bending in an inverted 'T' shape, It forms the outer rim, and the inner side forms the inclined rib and the through hole of the required part and the bending The eave bracket which forms the inter rib, and the inner side form the rib of the inclined state, and the light steel structure made from the ridge bracket which forms the passing hole of a required part, and the intermediate | middle rib which bends.

According to the present invention, since the structure material is lightweight, the basic construction cost is reduced and can be constructed by simply assembling in the field has the advantage of saving labor costs.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a partially omitted perspective view showing an embodiment of the present invention. In this figure, reference numeral 1 denotes a frame, 11 a fixed piece, 15 a unilateral plate, 17 a bilateral plate, 19 a cornice bracket, and 21 a ridge bracket.

As shown in FIG. 12, the frame 1 is bent at both sides at right angles to form a horizontal portion, and the ends thereof are folded inward to form ribs 5, and intermediate ribs are formed at intermediate portions along the long direction. 7) was formed.

The length of the frame 1 is not particularly limited, but it is preferable not to exceed a maximum of 7 meters so that standardization of the transport vehicle is possible. The fixing piece 11 is shown in FIG. It is generally bent in an 'L' shape, and the passage hole 2 is formed at a predetermined location. Similarly to the frame 1, the fixing piece 11 is formed with two intermediate ribs 7 at its intermediate portion.

Figure 4 shows a base plate forming a base for supporting the frame (1) is divided into one side and both sides, a through hole (2) is formed in a predetermined place, one side is bent in an approximately 'L' shape Both sides are bent in an inverted 'T' shape.

FIG. 5 shows the cornice bracket 19, and FIG. 6 shows the ridge bracket 21.

The cornice bracket 19 forms an outer rim connected to the curved portion 23, and the inner side forms an inclined rib 5, the passing hole 2 of the required portion and the intermediate rib 7 to be bent. To form.

The ridge bracket 21 has a configuration substantially the same as that of the eave bracket 19, and only the inclination angle of the outer edge and the inclination angle of the inner inclined rib 5 are different. The ridged bracket 21 also has a rib 5 in an inclined state, and forms a passing hole 2 in the required portion and an intermediate rib 7 that is bent. This intermediate rib 7 has an obtuse angle different from that of the cornice bracket 19.

Next, the construction procedure of this invention is demonstrated with reference to (a)-(g) of FIG.

Before detailed description, prepare standard drawings according to building size. A list of various main and subsidiary materials required for the standard drawing shall be prepared and the construction costs shall be determined. The package is transported to the construction site according to the standardized list of main and subsidiary materials.

According to the drawings, one side and the base plate (15), (17) and eaves using the eaves bracket (19) to stand the column. The pillar here means of course the frame 1. At this time, the pillar is erected and the foundation works. Since this is the only work fixed to the foundation concrete, special attention must be paid to its safety.

There are two ways to connect with the foundation. It is a pinned base and a fixed base. The former refers to a joining method by pins (bolts and nuts) in fixing both the side plates and one side base plate, and the latter is a method of embedding and fixing the base part with concrete.

The connection and fixation of the components and components adopted below is a method of contacting each desired component by inserting a normal fastening bolt into a passage hole 2 formed in each component of the present invention. Therefore, since there is no difficulty in assembly, even an unskilled person can assemble. In addition, if necessary, the strength of the frame 1 may be increased by constructing the frame 1 in a folded state in a back to back manner.

In the fixed bonding method, as shown in FIG. 9, one side or the base plates 15 and 17 are joined to the ends of the frame 1 used as the pillar material using bolts and nuts, and then embedded in concrete. After that, the fixing piece 11 is connected to both sides or one side of the pillar frame 1 according to the design. On the other hand, the pin bonding method, as shown in Figs. 2 (f) and (g), fixes one side and the base plates 15 and 17 to an anchor bowl (not shown) which is embedded in concrete g in advance. Assemble as much as possible. In this way, after installing the plurality of pillar frames 1 and connecting the beam frame 1, the basic work is finished, and then enters the upper joining work. That is, when two pillar frames 1 are installed, the beam frame 1 is connected to both pillar frames 1 using the fixing piece 11 to form an 'H' shape and the eave brackets 19 And using the ridge bracket 21 to install the roof frame (1).

At this time, for example, one side base plate 15 is used for the foundation portion where the door is installed, and both base plates 17 are used for the joint material or the middle portion of the building (see FIGS. 2 (f) and (g)). .

All parts of the present invention are mainly manufactured by hot roll forming, and parts having different thicknesses are used according to the use position. The main material uses the C section, and in this embodiment, the cold rolled steel sheets are standardized into 1.5 mm, 2.0 mm, and 2.4 mm. The height and width of the building are variable depending on the standard length of the columns and rafters, and the building's width can be extended up to 15M. However, this longest length is not particularly limited. You can extend it as long as you use the middle column.

According to the present invention, in the construction of a single building, it is possible to save labor costs by simply assembling and installing various main and subsidiary materials pre-processed at the factory without using heavy equipment at the construction site, and the entire assembly parts are completely As it is cut and has a through hole through which the bolt passes, even an unskilled hole can be easily assembled according to the assembly instructions.
