Figure 1 is a diagram showing the combination of a bracket and a beam according to the present invention.

As shown in FIG. 1, the present invention completes a long-span beam by combining the H-shaped beam 200 with the H-shaped bracket 100 previously coupled to the column C.

Although an H-shaped pillar (C) is shown in Figure 1, various shapes of pillars (C) to which the H-shaped bracket 100 can be coupled are possible. One end of the H-type bracket 100 is coupled to the column C, and the other end is coupled to the H-type beam 200. At this time, the lower flange 120 of the portion coupled to the H-shaped beam 200 may be formed longer than the upper flange 110.

As the lower flange 120 of the H-type bracket 100 is formed longer than the upper flange 110, the first inclined joint plate 140 coupled to the bracket is also formed to be inclined correspondingly. As shown in FIG. 1, the first inclined joint plate 140 is obliquely coupled to the end of the H-type bracket 100, but at this time, the first inclined joint plate 140 and the H-type bracket 100 are connected to each other by welding the contact areas. It can be joined.

The H-type beam 200 is coupled to the H-type bracket 100, and the first inclined joint plate 140 is coupled to one end of the H-type bracket 100, and one end of the H-type beam 200 facing this The second inclined joining plate 240 is coupled to the first inclined joining plate 140 and the second inclined joining plate 240 facing each other and joined to each other.

As the first inclined joint plate 140 and the second inclined joint plate 240 are joined to each other, the H-shaped beam 200 and the H-shaped bracket 100 are also joined to each other. Both the first inclined joint plate 140 and the second inclined joint plate 240 are formed to be inclined in the direction of the column C, and through this configuration, the parent due to bending applied to the joint area between the long span beam and the column C It is possible to respond more effectively to stress and shear forces.

In addition, when coupling the H-shaped beam 200 to the H-shaped bracket 100 that is previously joined to the column C, first lift the H-shaped beam 200 using a crane, etc., and then move it from top to bottom. The H-shaped beam 200 is seated on the H-shaped bracket 100. In this case, the first inclined joint plate 140 and the second inclined joint plate 240 are inclined in the direction of the pillar C. It is desirable.

Figure 2 is a diagram showing that the guide portion 141 is inserted into the insertion hole 241 and coupled when the bracket and beam according to the present invention are coupled.

As shown in Figure 2, when the H-shaped beam 200 is coupled to the H-shaped bracket 100, the H-shaped beam 200 is moved from top to bottom and seated on the H-shaped bracket 100. In this case, the guide portion 141 formed in the first inclined joint plate 140 is inserted into the insertion hole 241 formed in the second inclined joint plate 240.

By inserting the guide portion 141 into the insertion hole 241, the second inclined joint plate 240 can move along the guide portion 141 and accurately seat on the first inclined joint plate 140. At this time, the guide portion 141 may be formed as a left and right pair on the first inclined joint plate 140, and correspondingly, the insertion hole 241 may also be formed as a pair on the second inclined joint plate 240.

The worker simply works so that the guide part 141 of the first inclined joining plate 140 is inserted into the insertion hole 241 of the second inclined joining plate 240, and then the insertion hole of the second inclined joining plate 240 is inserted. As (241) moves along the guide portion 141 of the first inclined connecting plate 140, the first inclined connecting plate 140 and the second inclined connecting plate 240 come into exact contact.

In this way, the first inclined joint plate 140 and the second inclined connecting plate 240 are brought into contact, and then the first inclined connecting plate 140 and the second inclined connecting plate 240 are fastened to each other by a plurality of bolts. It can be. For this purpose, bolt fastening holes for bolts may be formed in advance in the first inclined joint plate 140 and the second inclined joint plate 240.

Through this, the present invention not only allows the H-shaped beam 200 to be easily coupled to the column C, but also more strongly resists negative moment or shear force at the end due to bending. As resistance to negative moment or shear force increases, the span length can be further extended.

Figure 3 is a diagram showing a truss-type reinforcing member being coupled to a beam according to the present invention.

As shown in FIG. 3, the H-shaped beam 200 according to the present invention may further include a truss-type first reinforcing member 250. By reinforcing the H-shaped beam 200 by combining the truss-type first reinforcing member 250, the rigidity of the H-shaped beam 200 can be further increased, and the span length can be further extended according to the increased rigidity. There will be.

At this time, the first reinforcing member 250 is composed of a plate member, and the side surface of the plate member may be coupled to the web of the H-shaped beam 200. The web of the H-shaped beam 200 and the side surfaces of the plate member may be joined to each other by welding.

In addition, as shown in FIG. 3, the first reinforcing member 250 extends obliquely from a portion where the second inclined joint plate 240 and the lower flange of the H-shaped beam 200 are joined to form a defect with the upper flange, The second inclined joint plate 240 and the first reinforcing member 250 may be formed in a structure that is integrated with each other.

Through this structure, the truss-type first reinforcing member 250 is integrated throughout the H-type beam 200, so it can be seen that the truss-type reinforcing members are combined throughout the H-type beam 200 and the H-type bracket 100. In the end, even though there is a joint area between the H-type beam 200 and the H-type bracket 100, the truss-type reinforcing member is continuously installed throughout the beam between the columns C, thereby increasing the rigidity of the H-type beam 200. This can increase significantly.

Figure 4 is a diagram showing that the reinforcing member coupled to the beam according to the present invention is made up of a plurality of reinforcing modules and coupled to the beam, and Figure 5 shows different examples of a plurality of reinforcing modules constituting the reinforcing member according to the present invention. This is the drawing shown.

The first reinforcing member 250 shown in FIG. 4 may have reinforcing plates coupled to its upper and lower portions, respectively. Among these respective reinforcing plates, the upper reinforcing plate 251 is coupled to the upper flange 210 of the H-shaped beam 200, and the lower reinforcing plate 252 is coupled to the lower flange 220 of the H-shaped beam 200. I do it.

Additionally, the first reinforcing member 250 and the reinforcing plates combined above and below the first reinforcing member 250 may be formed as one reinforcing module. These reinforcement modules can be manufactured in advance and coupled to the side of the H-shaped beam 200 as required.

Through this configuration, it is possible to adjust the number of reinforcement modules attached to the H-shaped beam 200 according to the design load. In other words, the required number of reinforcement modules can be combined with the H-shaped beam 200 to maintain the rigidity to resist the design load while taking the required number of long-span beams.

Figure 5 shows an embodiment different from the reinforcement module of Figure 4. As shown in FIG. 5, the reinforcement module may further include a connection reinforcement plate 253 connecting the upper reinforcement plate 251 and the lower reinforcement plate 252. In this case, a plurality of reinforcement modules can be manufactured in advance as shown in FIG. 4 and coupled to the side of the H-shaped beam 200 as required. In the reinforcement module according to Figure 4, the side of the plate member is coupled to the H-shaped beam 200, but in the reinforcement module according to Figure 5, the connecting reinforcement plate 253 faces the web 230 of the H-shaped beam 200. Face-to-face bonding takes place. Through this, the bonding force between the web 230 of the H-shaped beam 200 and the connecting reinforcement plate 253 increases, and ultimately the bonding force between the H-shaped beam 200 and the reinforcement module increases.

Figure 6 is a view showing that the bracket and beam according to the present invention include both truss-type reinforcing members, and Figure 7 shows the truss-type reinforcing member formed in the bracket and beam according to the present invention and integrated with the inclined joint plate. This is the drawing shown.

As shown in FIGS. 6 and 7, the H-type bracket 100 further includes a truss-type second reinforcing member connecting the upper flange and the lower flange of the H-type bracket 100.

The truss-type second reinforcing member may be attached to the web 130 of the H-type bracket 100.

Through this configuration, the rigidity of the H-type bracket 100 can be increased, thereby increasing resistance to shear force or bending moment.

In addition, the lower end of the second reinforcing member is coupled to the joint portion of the column C and the lower flange, and the upper end is coupled to the upper part of the first inclined joint plate 140 to form the second reinforcing member and the first inclined joint plate 140. can be integrated.

This integrated configuration becomes clearer in Figure 7. As can be seen in Figure 7, the second reinforcing member starting from the column C is connected to the first inclined joint plate 140 and the second inclined joint plate 240, and then the first joined to the H-shaped beam 200. It can be continuously connected to the reinforcing member 250. Through this configuration, the truss-type reinforcing members are continuously combined throughout the span beam, greatly increasing the overall rigidity.

Figure 8 is a view showing a reinforcement plate being coupled between a beam and a bracket according to the present invention.

As shown in FIG. 8, the correction plate 300 is additionally coupled between the first inclined joint plate 140 of the H-type bracket 100 and the second inclined joint plate 240 of the H-shaped beam 200. You can.

At this time, the correction plate 300 may further include a passage hole 301 through which the guide portion 141 can pass. That is, the guide portion 141 of the first inclined joining plate 140 passes through the passage hole 301 and is inserted into the insertion hole 241.

Additionally, the correction plate 300 may further include a bolt fastening hole for coupling the first inclined joint plate 140 and the second inclined joint plate 240.

When explaining the process of coupling the H-shaped beam 200 to the pillar C, first, a pair of H-shaped brackets 100 are installed on both pillars C, respectively. And the H-shaped beam 200 is installed between a pair of H-shaped brackets 100. In this case, the length of the H-shaped beam 200 cannot be manufactured larger than the distance between the H-shaped brackets 100. In other words, the length of the H-type beam 200 must be manufactured equal to or smaller than the distance between the H-type brackets 100.

When the length of the H-type beam 200 is manufactured smaller than the distance between the H-type brackets 100, the compensation plate 300 is inserted between the first inclined joint plate 140 and the second inclined joint plate 240. This makes it possible to correct the length of the short H-shaped beam 200.

Through the correction plate 300, it becomes easier to manufacture the length of the H-type beam 200, and further, even when the H-type beam 200 is short, the H-type bracket 100 and the H-type beam 200 are formed through the correction plate 300. ) can make up for the gap between them.

The scope of protection of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is added once again that the scope of protection of the present invention may not be limited due to changes or substitutions that are obvious in the technical field to which the present invention pertains.
