Description

Flange-Web Reinforced Sections{Steel Pile with Reinforced Flange and Web}

The present invention relates to a rolled section steel or a welded section steel composed of a flange and a web used to form civil engineering and construction structures, and more specifically, to a section steel reinforced with a flange and/or web, and more specifically, a flange and/or Or for welded section steel with reinforced web.

In addition, the present invention relates to a section steel or welded section steel in which a flange and/or a web is reinforced using a flange reinforcement and/or a web reinforcement.

The present invention is also directed to an Ent Roger-type steel tube section using a flange and/or a web and/or a flange reinforcement and/or a web reinforcement thus reinforced.

As a steel material for civil engineering and building structures, rolled H-beams are generally used in various ways as structural members such as beams, columns, bridges, piles, bridges, and temporary facility constructions of buildings.

H-beam is composed of a flange member and a web member, and due to the characteristic of its shape, there are strong and weak axes according to the load direction, and local buckling and plate buckling of the flange member and web member according to the load direction occur. Bending/shearing/compression shear failure of the H-beam member may occur, and in order to compensate for this, many reinforcing materials are additionally installed and used.

In addition, welded H-beams may be used by additionally installing web members to complement the shear structural performance of the web members. However, in the case of H-beams reinforced in this way, the steel plate must be cut and welded. Only the outer part in contact with the member can be welded, and if two web members are described as an example, the space (d) between the web and the web as shown in Fig. 1(b) and the inner side where the flange member and the web abut The part has fragility in the manufacturing part because it is difficult for the worker's hands or tools to enter it, so it cannot be welded.

In addition, eccentricity may act when a load is applied to the reinforced H-beam due to differences in the number of welded portions, welded areas, and welded portions, which is an essential structural weakness of the welded section steel.

When a compressive load is applied in the direction perpendicular to the flange of the H-beam (strong axial direction), the flange member is subjected to bending stress due to the moment and the web member is subjected to shear stress. In this case, local buckling or plate buckling may occur in the flange member and the web member, and when a compressive load is applied in the direction of the web member (weak axis direction) of H-beam, the web member receives bending stress and shear stress occurs in the flange member. As a result, more local buckling occurs in the flange than when a load is applied in the strong axis direction.

In addition, in the case of using such H-PILE (H-beam) as a support beam, H-beam has an asymmetric cross section, each of which has a weak axis and a strong axis, so the need to reinforce the weak axis when designing buckling against the compressive load transmitted from the soil wall through the strip. There is this.

On the other hand, as the need for expansion of social indirect facilities has recently increased, many underground excavation works in the city center are in progress. The characteristics of such underground excavation work are close-up construction in which subways, overpasses, underground structures, and ground structures for office spaces and residential spaces are in close proximity, and maximum space excavation and deep excavation to maximize the use of limited underground space. have.

In particular, in the underground excavation work for constructing a large-scale underground structure in a limited space in an urban area, the stability of the surrounding ground should be of the utmost priority. Therefore, the soil barrier construction required to maintain the stability of the surrounding ground must be reviewed, and the selection of the soil barrier method is considerably in the construction plan. It occupies an important part. The soil barrier construction method can be divided into two main methods: a method of utilizing a temporary soil barrier structure, and a method of constructing an underground structure in parallel with excavation work, and the structure acts as a barrier wall in response to earth pressure and water pressure. There is a risk of collapse of the tent structure due to the possibility of inducing civil complaints and stability problems of the surrounding ground, and there are quite a number of cases that have actually collapsed. In addition, there are many cases in which civil complaints are generated due to the displacement of the surrounding ground, resulting in suspension of construction or compensation for civil complaints.

Temporary facilities used for earthwork in the current earthworks are steel piles and earth plates, or CIP (Cast in Place Wall), SCW (Soil Cement Wall), etc. are used, and the support type is supported by conventional temporary struts. There are two ways to do it and to support it with Earth Anchor, Soil Nailing, Rock Bolt, and Top-Down method.

Of these, if a temporary strut is used, it is highly likely to increase the amount of air due to the installation and dismantling process of the temporary material, and to cause the change of the surrounding ground when dismantling, but the working environment during underground construction is relatively good compared to the Top-Down method. It has the advantage of reducing the cross section of the slab, so it is currently widely used.

In the case of using H-beams as such a support, H-beams are not permanently installed on the structure, but are dismantled and recycled after the underground soil barrier construction is completed. Therefore, it is very important to strengthen the stiffness of H-beams to prevent deformation of H-beams due to repeated use in the case of using H-beams as support beams. That is, it is also very important to improve the member recovery rate by minimizing cross-section damage or destruction caused by repeated use of H-beams, and the need for rolled H-beams reinforced with flanges and webs is greatly increasing.

Therefore, conventional rolled H-beams manufactured as ready-made products cannot satisfy all of the above technical requirements due to the standard of the cross section or the ready-made manufacturing method, and a new method of section steel is required.

Of course, it may be different in individual descriptions for convenience of description.

The present invention is to propose a new concept of section steel, specifically H section steel or generally'H' letter or generally'ㅁ' letter or similar shape of section steel, and in general, H section steel is a welded or rolled section steel, That is, it is manufactured by welding or rolling the upper and lower flanges and a web in the middle thereof, but the section steel of the present invention is not limited to welded section steels, as it is not necessarily required to be coupled by welding.

In order to more effectively describe the present invention, which presents a new concept of section steel, before describing various embodiments, elements (parts) of each component forming the section steel will be described.

Parts

The section steel of the present invention is largely composed of a flange, a web, and various reinforcing materials.

FIG. 2 shows a conventional flange 13, and consists of two upper and lower parts in a normal H-beam, and in the embodiment of the present invention, as in FIG. 25, the outer side of the web 20 and the inner side of the upper and lower flanges are mutually It can be welded together, and the inner side (d) of the web of FIG. 1B and the inner side of the upper and lower flanges are not welded, but only contact is made.

The flange 10 will be described with reference to FIG. 3. The flange 10 is formed in one row of reinforcing holes h1 in the inside of the flange 13 of FIG. 2 along its longitudinal direction L, and preferably, the reinforcing holes 11 are in the longitudinal direction of the flange ( It is formed by extending in L) so that a plurality of them are arranged in the longitudinal direction (L). The reinforcing hole 11 may be referred to as a flange reinforcing hole because the protrusion p1 of the web 20 to be described later is inserted to reinforce the flange. In this specification, it may be referred to as a reinforcing hole (h1).

In the present specification, various flanges, webs, reinforcements, etc. are all referred to identically, but are distinguished by different reference numerals.

The protruding protrusions p1 formed above and below the web 20 to be described later may be inserted from the inside to the outside of the flange 10 to protrude or be exposed to the outside of the flange reinforcing hole h1. Thus, the protrusion p1 of the web 20 or the like protruding from the outer surface of the flange 10 and the flange 10 and/or the flange reinforcing hole h1 are fixed by contact or welding.

In this way, the protrusion (p1) may be inserted into the flange and protruded outside the flange to be welded to the flange, but simply the head of the protrusion is exposed to the outside of the flange to form a substantially flat surface with the flange surface and the protrusion. Can be welded.

In the present invention, the projections (p1) and protruding outward of the flange are exemplarily illustrated in the drawings and the specification, and have been described mainly, but as described above, simply'exposed' to the outside to form a substantially flat surface with the flange surface. It is also possible.

The same applies to the description of the protrusions (g, k) or other protrusions (p2) of the reinforcing member being inserted into the reinforcing hole of the web, the reinforcing hole of the flange, the reinforcing hole of the'C'-shaped reinforcing member.

In addition, in the present invention, a configuration in which a protrusion or the like is “protruded” so that a protruding portion such as a protrusion is welded between the surface of the inserted member is'exposed' to the surface of the member into which the protrusion is simply inserted, and the protrusion and the corresponding member It is included in the scope of the right that the face of the face is substantially flat.

When such a flange 10 is employed, when a plate deformation such as torsion and local buckling occurs in the web, the flange due to the connection or contact between the protruding protrusions (p1) of the web (20, etc.) and the inside of the flange reinforcement hole (h1). As it behaves integrally with (10), the structural performance of the web 20 can be reinforced.

As shown in FIG. 26, the protruding protrusion p1 of the web 20 may have an increased length protruding to the outside of the flange 10, and a separate bolt portion 31 is provided in the protruding protrusion p1 with an increased protruding length. ) Can be formed. The bolt part 31 may be bolted to a bolt connection part 33 formed on the web 32 of a separate member 30 such as a beam and a column. That is, the protruding protrusion p1 of the flange 10 may serve as a connecting member with other members.

In general, the method of welding the steel plate to the flange 10 and connecting it to the other member 30 is only joined by welding the steel plate and the flange, but the other member 30 and the other member 30 using the protruding protrusion p1 as in the present invention. When the connection method is employed, the protrusion p1 is welded from the outside of the flange 10 and at the same time is supported by the flange reinforcing hole h1 to be firmly supported by the flange 10, Since it is connected to the bolt portion 33, the connection portion between the flange 10 and the other member 30 may be more rigid.

The protrusion p1 protruding from the flange 10 may be supported inside the reinforcing hole p1 and welded from the outside to be more firmly fixed to the flange 10.

As can be seen in FIG. 25, the protruding protrusion p1 of the web 20 may be welded with the flange 10 at the outer portion of the flange 10, and additionally, the flange 10 at the inner side of the flange 10 Welding can also be carried out at the portion where the and the web 20 are in contact, so that the protruding protrusion p1 can be double-welded inside and outside the flange, so that the protruding protrusion can be fixed more firmly.

In other words, the protruding protrusion (p1) is fixed by welding inside and outside the flange 10, respectively, and at the same time, it is possible to expect a triple reinforcing effect supported through the reinforcing hole h1 formed inside the flange 10. .

In the flange 11 of FIG. 4(a), reinforcing holes h1 may be formed in two rows along the longitudinal direction L of the flange. The flange reinforcing hole h1 is a hole into which the protrusion p1 of the web 20 is inserted, and two webs 20 may be coupled to the flange 11 as in the 1-2 embodiment of FIG. 27. have.

If there are two or more webs, the flange cannot be welded to the inside of the web, and only the outside can be welded, but due to the protruding protrusion structure of the web, the section where welding cannot be performed on the inside of the web is protruded or exposed. Welding can be performed on the outer surface of the flange and the protrusion, so that the structure of the flange and the web can be integrated.

If there are two or more webs above, the reason that welding cannot be performed on the inner side (d) of the web is because the welding mechanism or the hand of the worker cannot be inserted in the section d of FIG. 1(b).

In the flange 36 of FIG. 4(b), the flange reinforcement hole (h1) is formed in three rows in the longitudinal direction (L), and the flange 37 of FIG. 4(c) has the flange reinforcement hole (h1) in the longitudinal direction (L). ) Is formed in 4 rows.

The flange 12 of FIG. 5 is in the width direction (W) of the flange in addition to the longitudinal reinforcement hole (h1) of the flange 10 of FIG. 3 or the flange 11 of FIG. 4(a). A reinforcing hole h3 is formed in which the extending transverse reinforcing hole h2 is additionally formed. Accordingly, the flange 12 may have a plurality of reinforcing holes h3 such as a cross shape (+) along the longitudinal direction L of the flange 12.

As in the 1-3 embodiment of FIG. 28, the reinforcing hole h3 is a reinforcement in which the thickness t of the reinforcing material 40 of FIG. 16 and the protrusion p1 of the web 20 are inserted to protrude. It's a hall. In the reinforcing hole h3, the thickness portion t of the reinforcing material 40 and the protrusion p1 of the web 20 are inserted and protruded to prevent deformation of the flange member when a load such as buckling or twisting is applied to the flange member. prevent. The reinforcing member 40 may be welded to the inner and outer sides of the upper and lower flanges at the same time.

In the flange 14 of FIG. 6, a plurality of reinforcing holes h2 extending in the width direction W are formed in one row in the longitudinal direction L of the flange. In the reinforcing hole h2, the flange reinforcement 43 of FIG. 19 is inserted to reinforce the flange from the inside, and the protrusion k2 of the reinforcing material 43 protrudes from the outside of the flange 14 and the flange 14 Can be welded.

Such a flange reinforcement hole (h2) through the reinforcing member-flange to organically transfer the load to each other and to prevent buckling.

The flange 15 of FIG. 7 (a) has a reinforcing hole h1 as in FIG. 3 and a reinforcing hole h2 as in FIG. 6 applied together, and the reinforcing hole h1 is the longitudinal direction (L) of the flange. It is formed in two rows and the reinforcing holes h1 of the two rows are spaced apart in the width direction (W). A transverse reinforcement hole h2 is arranged between the two rows of longitudinal reinforcement holes h1 to form a reinforcement hole h4 formed in a shape similar to the English capital letter I (I). The reinforcing holes h4 are formed alternately with those having only the reinforcing holes h2.

The reinforcing hole h1 protrudes by inserting the protrusion of the web, and the reinforcing hole h2 protrudes by inserting the protrusion of the flange reinforcing material. In this way, both the web and the flange reinforcement are inserted to form a structure that transmits the load and complementary reinforcement between the web-flange reinforcement-flange. When a load is applied to the flange 15, the load does not all act on the flange, and the three members of the flange 15, the stiffener 43, and the web 20 receive the load, so that the effect of distributing the load can be expected. .

In the flange 19 of FIG. 7(b), a plurality of reinforcing holes h4 of FIG. 7A are arranged in two rows in the width direction (W) and formed in the length direction (L).

In the flange 16 of FIG. 8(a), the transverse reinforcing holes h2 as in FIG. 6 are formed in two rows along the longitudinal direction L of the flange. The flange 16 is composed of two rows of reinforcing holes (h2) into which a flange reinforcement (43, etc.) can be inserted and protruded from the flange. It is possible to form a structure in which the generated load is mutually shared with the flange.

The flange 34 of FIG. 8(b) has three rows of transverse reinforcing holes h2. The reinforcing hole h2 is called a transverse reinforcing hole because it extends in the flange width direction W, that is, in a direction perpendicular to the longitudinal direction in the longitudinal direction to form a groove.

The flange 17 of FIG. 9 (a) has a reinforcing hole h1 into which a protruding protrusion of the web 20 can be inserted along the longitudinal direction (L) central axis, and the reinforcing hole h1 It has a structure in which reinforcing holes h2 into which a flange reinforcing member 43 can be inserted are formed on both sides of the width direction (W). A group of reinforcing holes in which the longitudinal reinforcing holes h1 and the transverse reinforcing holes h2 are arranged together is referred to as a reinforcing hole h5. In the flange 17, only the reinforcing holes h2 are arranged in two rows, and the reinforcing holes h5 are alternately arranged.

It is different from the reinforcement hole (h3) of the flange 12 in that the reinforcement hole (h1) and the reinforcement hole (h2) of the reinforcement hole (h5) are not connected to each other, and two reinforcement holes (h1) and the reinforcement hole (h2) ) It is distinguished from the reinforcement hole (h4) of the flange 15 consisting of one. The reinforcing holes h5 of the flange 17 and the reinforcing holes h4 of the flange 15 are arranged along the longitudinal direction (L) central axis, in addition to the number of longitudinal and transverse reinforcing holes being reversed. The flange 15 is a transverse reinforcement hole, whereas the flange 17 is a longitudinal reinforcement hole, which is also different.

Flange 15 is a structure in which a flange reinforcement reinforces the central part of the flange inside the flange plane, and the web reinforces the left and right sides of the central part of the flange, and the web complements the performance of the flange reinforcement by in close contact with the flange reinforcement from left and right. It has the effect of doing so, and there is no separate reinforcement for the flange portion protruding outward of the web. Therefore, it is more advantageous for web reinforcement (shear reinforcement) in a load state in which a vertical load is applied to the flange of the section steel.

In the flange 17, the web is installed in the center of the flange to reinforce the flange, and the flange reinforcement is installed on the left and right sides of the web to reinforce the performance of the web, and also the protrusion (g) of the flange reinforcement and the reinforcement hole (h2) of the flange. By combining the flange reinforcement to the left and right ends of the flange can perform the function of preventing the plate buckling of the flange. Therefore, it is more advantageous for flange reinforcement (bending reinforcement) in a load state in which a vertical load is applied to the flange of the section steel.

In the flange 18 of FIG. 9(b), a longitudinal reinforcement hole (h1) is formed in three rows in the width direction (W), and a transverse reinforcement hole is formed between the longitudinal reinforcement hole (h1) and the longitudinal reinforcement hole (h1). (h2) is arranged to form a reinforcing hole (h6).

In the flange 35 of FIG. 9(c), a longitudinal reinforcement hole (h1) is formed in four rows in the width direction (W), and a transverse reinforcement hole is formed between the longitudinal reinforcement hole (h1) and the longitudinal reinforcement hole (h1). (h2) is arranged to form a reinforcing hole (h7).

The web members 20, 21, 22, 23, 24, 25 constituting the section steel of the new concept of the present invention will be described below.

Fig. 10 shows a conventional web 25, which is arranged between a flange composed of two upper and lower sides in a conventional H-beam. As in Fig. 1, a height portion H of the web 25 is arranged between the inner side of the upper flange and the inner side of the lower flange, and the length D of the web generally corresponds to the length L of the flange. The web 25 is the height of the web 25 on the inside of the upper and lower flanges 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 34, 35, 36, 37 as in FIG. It is a configuration in which the flanges are welded to each other in both sides in the direction H (see Fig. 25 and the like).

For reference, in the present invention, “L”, “W”, “H”, and “L(D)” indicated by left and right arrows are used together in different drawings, but the length or width of the surface of the member marked with the same mark must be It is not meant to be the same, but to explain that the installation directions of the members are the same or correspond to each other. In addition, when two English characters are used together, such as “L(D)”, the two English characters are in substantially the same direction, for example, the longitudinal direction of the flange (L) and the longitudinal direction of the web (D) are substantially the same. Means to represent.

For example, the width (Y) (W) of the reinforcing material in Fig. 17 is not the same size as the width (W) of the flange in Fig. 2, but the width (Y) and the width of the flange (W) are parallel to each other. By showing that they are installed, the directions of installation of members of similar shapes in the present invention are to be easily distinguished by the above notation.

Similarly, the width (X) (W) of the reinforcing material in FIG. 18(a) is also indicated to mean that the width (W) of the flange in FIG. 2 and the arrangement direction are the same, and that the width of the reinforcing material and the width of the flange are the same. no. To distinguish this, the width of the reinforcing material is marked with (X), but as described above, even if there is no additional marking, the markings of L, W, H, etc. are the same, meaning that the width or length of the corresponding side is the same. no.

In the web 20 of FIG. 11, protruding protrusions p1 that can be inserted or penetrated into the longitudinal reinforcing hole h1 formed inside the flange are at regular intervals in the longitudinal direction L at the upper and lower portions of the web 20, respectively. Is formed. The flange and the web 20 are welded to each other from the inside of the flange, and the protruding portion of the protrusion (p1) is welded to the flange from the outer surface of the flange, so that the flange-web is mutually integrated through the protrusion (p1). Can be secured. The protruding protrusion p1 can achieve an effect of preventing deformation of the flange when twisting and buckling of the flange occurs.

In addition, when the web 20 is installed in two or more rows as shown in FIG. 27, the inner side (d) between the web and the web cannot be welded, but the protrusion (p1) protruding like the web 20 is If included, the protruding portion of the protrusion p1 is welded to the outside of the flange, so that the flange-protrusion-web may be interconnected by welding.

In the web 21 of FIG. 12, a plurality of longitudinal reinforcing holes e1 extending in the longitudinal direction are formed in one row along the longitudinal direction L thereof. In the reinforcing hole e1, a protrusion p2 of the reinforcing material 41 as shown in FIG. 29 may be inserted from the inner side d of the web 21 to protrude outside the reinforcing hole e1.

The protrusion of the reinforcing material 41 protruding from the outside (c) of the web 21 and the web 21 may be welded. In the inner side (d) of the web 21, the reinforcing material and welding are not made.

Two or more webs 21 may be installed between the upper and lower flanges, thereby preventing plate buckling according to the width-thickness ratio of the flange. In this case, between the web 21 and the web 21 (d), a filler material such as concrete (z) is used, and the stiffness of the flange-web structure itself can be increased through the inside of the filling material.

The web 22 of FIG. 13 is a combination of the shape of the web of FIGS. 11 and 12, and protruding protrusions p1 that can be inserted or penetrated into the reinforcing hole h1 formed inside the flange are formed at regular intervals. , It can be welded to each other with the flange on the inside and outside of the flange. On the inner side of the flange, the protrusion and the web may be welded together, and on the outside of the flange, the protruding portion of the protrusion may be welded to the flange.

That is, while the flange and the protrusion are welded on the outer surface of the flange through the protruding protrusion p1, the web can be welded to the flange through the protrusion integrally formed with the web. The protruding protrusion p1 may have an effect of preventing deformation of the flange when torsion and buckling of the flange occur.

When the web 22 is installed in two or more rows, the web and the inside of the web (d) cannot be welded, but the flange and the web can be welded from the outside of the flange through the protruding protrusion (p1). Can be expected.

In addition, a reinforcing hole (e1) through which the web stiffener 41 is inserted and penetrated is formed inside the web, and it is not welded to the web stiffener from the inside of the web 22, but the protrusion p2 protrudes from the outside of the web. The portion may be combined with the web reinforcement 41 by welding or the like.

Two or more webs 22 may be installed to prevent plate buckling according to the width-thickness ratio of the flange. Additionally, the rigidity of the flange-web structure itself can be increased by filling the inside between the web and the web by using a filler such as concrete.

In the web 23 of FIG. 14, a plurality of reinforcing holes e2 extending in the height direction (H) are installed in the longitudinal direction (L) of the web 23, and a protrusion (g) inserted into the reinforcing hole (e2) ) Is formed web reinforcement (42, 44, 45, etc.) is connected.

The web reinforcement members 42, 44, 45, etc. may be bonded in a contact manner or with an adhesive such as a metal bond within the reinforcing hole e2 of the web 23. In addition, it may be inserted into the reinforcing hole e2 of the web reinforcing material and welded to the protruding protrusion g.

Due to the coupling between the reinforcing holes e2 formed in the web 23 and the protruding protrusions of the web reinforcing material, a structural function of preventing local plate buckling of the web reinforcing material 42 may be performed. In addition, local buckling of the web 23 itself can be prevented by making it integrally behave with the web 23 by the protruding protrusions of the web reinforcing material.

In addition, it is welded to the web stiffener at the left and right outer sides (c) of the web, and can be combined with the web stiffener through the inner reinforcement hole (e2) of the web 23, so that the load transfer and load distribution between the web and the web reinforcement are complemented. It is a structure that can expect an action effect.

The web 24 of FIG. 15 is a combination of the web 20 and the web 23. The web 24 has protruding protrusions p1 that can be inserted or penetrated into the reinforcing hole h1 formed inside the flange at regular intervals, and the flange and the web are welded to each other from the inside of the flange, and also protrude. The flange and the web can be welded on the outer surface of the flange through the protrusion p1, and the protruding protrusion p1 can prevent deformation of the flange when twisting and buckling of the flange occurs.

When the web is installed in two or more rows, the inside of the web cannot be welded, but the flange and the web can be welded from the outside of the flange through the protruding protrusion p1. In addition, a reinforcing hole (e2) through which a protrusion (g) formed in the web reinforcing member 42 is inserted and protruded is formed inside the web member, and the web reinforcing member is bonded to the inside of the web by contact or an adhesive. The reinforcing hole (e2) formed inside the web reinforcement member is integrally operated with the web reinforcement member 42 by inserting and coupling the protruding protrusions, thereby increasing the inertia, thereby preventing the local plate buckling between the web stiffener and the web. can do.

In addition to the welding connection between the web and the web reinforcement on the outside of the web, the double bonding force can be expected by coupling with the web reinforcement through the reinforcement hole (e2) of the web, so that the load transfer between the web and the web reinforcement and The load-bearing supplement effect is possible.

Reinforcing materials such as a flange reinforcement material and a web reinforcement material constituting the section steel of the new concept of the present invention will be described below.

The reinforcing material 40 of FIG. 16 is a flange reinforcement of a generally triangular or right-angled triangle, and a thickness portion (t) is formed on two sides excluding the hypotenuse, so that the thickness portion (t) is a reinforcing hole formed in the flange or web. It can serve as a protrusion that can be inserted into.

That is, while one thickness portion (t) is bonded to one side of the web by welding or the like, the other thickness portion (t) may be inserted into the reinforcing hole (h3 in FIG. 5) of the flange to protrude. The protruding thickness (t) prevents buckling and twisting due to the load of the flange member, and does not directly transmit the load generated from the flange to the lower flange, but transmits the load to the web member, so that the flange -> flange reinforcement on one side ( 40) -> Web -> It can bring the effect of complementing and distributing the load generated by the flange reinforcement 40 on the other side installed symmetrically.

In general, in the case of ready-made H-beams, the load acting on the flange by welding the reinforcing stiffener inside the H-beam is transferred to the reinforcing stiffener, and this load is transferred back to the lower flange, resulting in local deformation of the flange. When the stiffener 40 of 16 is installed on the left and right sides of the web and inside the upper and lower flanges (part b in Fig. 1), the load loaded on the flange is transmitted to the stiffener 40, and a part of this load is transferred to the other side symmetrical through the web. It is also transmitted to the reinforcing member 40, and the load is transmitted vertically through the web, reaching the center of the lower flange. Through this, it is possible to reduce or prevent deformation of the lower flange by distributing the load loaded on the upper flange. Of course, some of the loads transferred to the lower part may be transferred to the lower flange through the stiffener 40 installed in the lower part, but due to the stiffener installed in the lower part, the width-thickness ratio of the left and right sides of the flange decreases, thereby reducing the local buckling of the lower flange. You will be able to improve.

In an embodiment in which the load of the reinforcing member 40 itself is transmitted to the web and the protrusion is formed on the web, the lower flange may share the load again due to the protruding protrusion of the web.

The stiffener 40 may be welded by protruding the thickness t of the stiffener 40 from the outer side of the flange 12 of FIG. 5, and may be welded together with the web 20 from the inner side of the flange 12. (See Example 1-3 in Fig. 27).

The shape of the reinforcing member 40 is a plate shape such as a steel plate, a'ㄱ' shape, a'ㄴ' shape, a'ㄷ' shape, a'ㅁ' shape, a'ㅇ' shape, a'H' shape, and a'I' It is implemented in various forms such as a'shape', and this specification mainly describes the'a' shape.

The flange reinforcement 40 of FIG. 16 has a similar cross-sectional shape ('ㄴ') or a'c' shape in that the longitudinal direction (L) of the flange does not extend entirely along the longitudinal side of the flange. It is different from the reinforcing members 60 and 61.

The reinforcing material 41 of FIG. 17 is inserted into the inside between the webs 21 and 22 and the webs 21 and 22 of FIGS. 12 to 13 and penetrates through the reinforcing hole e1 formed in the web and protrudes p2. ) Is a structure formed up and down in the longitudinal direction (L) of the reinforcement member 41 in the width direction (Y) (W), and is inserted into the inside of the web member to supplement and prevent buckling and torsion occurring in the web member. can do.

In addition, in order to compensate for the structural weakness caused by the inability to weld between the web member and the inner side of the flange (d) when the web members are installed in two rows, the outer side (c) of the left and right webs through the protruding protrusions (p2) Welding connection between the reinforcing members 41 and integrating them can prevent plate deformation and buckling of the web member. That is, two webs arranged left and right with the reinforcing member 41 interposed therebetween and connected to the reinforcing member 41 may be welded to the reinforcing member 41.

In addition, buckling of the web is prevented because the reinforcing material 41 is coupled between the webs, and thus, the load generated from the flange can be more efficiently distributed. In addition, when a load is applied in the weak axis direction of the member, the web structurally acts as a flange (bending stiffener), and the flange serves as a web member (shear stiffener). In this case, two protruding protrusions (p2) The stiffener 41 may serve to reinforce the shearing performance of the web serving as a flexural stiffener.

The reinforcing material 42 of FIG. 18 (a) is welded from the inside of the upper and lower flanges in the height direction (H), and a protrusion g that can be inserted into the reinforcing hole (e2) formed in the web in the width direction (W) is It is formed on one side.

In the reinforcing member 47 of FIG. 18(b), the protrusions g are formed on both left and right sides. The reinforcement member 47 looks similar in appearance to the reinforcement member 45 in which the height direction (H) protrusion (k) and the width direction (W) protrusion (g) are formed together, but in the reinforcement member 45, the protrusion (k) is A separate between the protrusion (g) and the protrusion (k) so that the flange to be inserted and the flange into which the protrusion (g) is inserted cannot directly meet at the stiffener 45, so that the protrusion (g) and the protrusion (k) are not directly connected. Stage is installed.

In addition, the reinforcing material 47 and the reinforcing material 43 also look similar in overall appearance, but are distinguished by different positions at which protrusions having a size that can be inserted into the reinforcing holes (h1, e2, etc.) are formed.

Such a reinforcing member 42 is a configuration that can be coupled by contact or an adhesive within the reinforcing hole (e2) of the web 23 in a pair as shown in FIG. 31A. Local buckling of the web is prevented by being coupled to the web 23 through the protruding protrusion g, and the reinforcing material 42 is integrated with the web through the reinforcing hole of the web. Since the stiffness is improved, buckling of the reinforcing material 42 itself can be prevented, and thus, structurally, mutually complementary functions can be performed.

In addition, when a load is applied to the flange, the flange load is transmitted to the web, and the web is buckling due to this load, and the protruding protrusion (g) inserted into the web transmits the load generated from the flange through the web. ) To prevent local buckling of the web and thereby distribute and support the load of the flange.

In the reinforcing material 43 of FIG. 19, protrusions k protruding so as to be inserted into the reinforcing holes of the flange are formed vertically. The side surfaces of the reinforcing member 43 may be joined by contact or a bonding agent without being welded to the web member, and the upper and lower portions of the reinforcing member 43 may be welded through the flange and the reinforcing hole outside the flange. That is, the reinforcing material 43 can be distinguished from each other in the upper and lower sides and the side that the flange and the web are joined.

This stiffener 43 is a structure that directly supports a part of the load generated from the upper flange and transmits a part to the lower flange.

The reinforcing material 44 of FIG. 20 has protrusions k that can be inserted into the reinforcing holes of the flange at the upper and lower portions, and protrusions g that can be inserted into the reinforcing holes of the web are formed on one side thereof. 20(a) and 20(b) are shown separately according to the length and length of the width (X) (W) of the reinforcing material, and the basic structure is the same. Both Figs. 20(a) and 20(b) are used in a manner that is coupled to the web on the left and right sides of the web. Fig. 20(a) is suitable for use when there is only one web, and Fig. 20(b) shows the web In the case of two, since the width (X) (W) of the reinforcing member 44 must be reduced by that amount, it may be suitably used at this time.

Of the left and right surfaces of the reinforcing member 44, the surface f on which the protrusion g is not formed has no contact with other members when the protrusions g of the reinforcing member 44 are arranged to face the inside of the section steel, The surface on which the protrusion g is formed is interpolated into the web and protrudes (Fig. 49, etc.). On the other hand, when the protrusions (g) of the reinforcing member 44 are arranged to face the outside of the section steel, the surface (f) of the left and right surfaces of the reinforcing member 44 on which the protrusions (g) are not formed will face the web 25. Can (Fig. 55, etc.).

The upper and lower surfaces of the reinforcing member 44 are formed with protruding protrusions k that can be inserted into the upper and lower flanges.

The reinforcing member 44 is inserted into the reinforcing hole of the upper flange and is welded to the outside of the flange through a protruding protrusion k, and may be welded to the web through a reinforced protrusion g on one side.

When the reinforcing member 44 is installed inside the web 23 and the web 25 as shown in FIG. 55, it may be welded to the web 23 through a protrusion g. At this time, the protrusion g of the reinforcing material 44 may be arranged to face the outside of the web 23 and the surface f without the protrusion faces the inside of the web, that is, the web 25.

In this case, the load acting on the upper part can be directly transmitted to the lower flange and the structure in contact with the lower part.

The load acting on the top may be distributed to the web through the protrusion g on the side of the reinforcement. In addition, as shown in FIG. 49, when the protrusion g is directed toward the inside of the section steel, that is, the web 23, the load transmitted from the protrusion g on the side is transmitted to another stiffener facing the flange- It can generate the effect of organically distributing the load between the web and the reinforcement.

In addition, the protrusions k of the left and right reinforcing members 44 are inserted into the reinforcing holes h2 of the flange to reinforce the flange and increase the buckling performance of the upper and lower flanges.

In the reinforcing material 45 of FIG. 21A, protrusions k are formed in the upper and lower sides, and protrusions g are formed in the left and right. Both sides of the reinforcement 45 are inserted into the web and protrusions g are formed, and the upper and lower surfaces of the reinforcement 45 are formed with protrusions k that can be inserted into the upper and lower flanges. It is joined to the flange.

Through this, it is possible to integrate the upper and lower flanges and the left and right webs by welding each through protrusions (g, k) protruding from the outside. This makes it possible to evenly distribute the load generated on the members to all members. In addition, the reinforcing material 45 is not welded from the inside of the flange and the web, but can be integrated by welding from the outside of the flange and the web through protruding protrusions g and k.

Buckling that may occur in the web due to the load applied to the flange can be prevented with the reinforcing material 45. The load generated from the flange is directly transmitted to the web and the reinforcing member 45 through the protruding protrusion k, thereby facilitating the distribution of the load between the flange, the web and the reinforcing member.

The reinforcing member 46 of FIG. 21B is used in the 7-1 embodiment of FIG. 89 and is used for an enclosure-type steel pipe section including a steel pipe 38.

A protrusion m that can be inserted into the reinforcing hole j1 of the'c'-shaped reinforcing material 60 is formed on one side, and the other side where the protrusion m is not formed is an opening of the'c'-shaped reinforcing material It faces (j4), and the protrusion (m) passes through the reinforcing hole j1_ of the'C'-shaped reinforcement material to be connected to the circumferential surface of the steel pipe 38.

The'c'-shaped reinforcement 61 of FIG. 22A is configured in a'c'-shaped cross-section and extends in the longitudinal direction (L) (D) of the flange or web and is installed between the upper and lower flanges. A protruding surface j2 is formed from both ends of one surface j3 extending vertically in the height direction H of the web, and an opening j4 surrounded by the one surface j3 and the protruding surface j2 is formed.

When the reinforcing hole j1 is formed on one side j3, it is the reinforcing material 60 of FIG. 23.

Unlike the reinforcement material 40 of FIG. 16, the reinforcing material 62 of FIG. 22B does not have a thickness t inserted into the reinforcing hole, and has a generally'b'-shaped cross-section in the longitudinal direction (L) of the flange or web. It extends along the flange or web. The reinforcing member 62 is installed between the inner side of the flange and the outer side of the web or'c'-shaped reinforcement to make the connection between the flange and the web or'c'-shaped reinforcement more solid. In addition, it is possible to secure a rigid connection for the entire longitudinal direction of the flange and the web or'C'-shaped reinforcement.

The reinforcing material 62 is in various forms such as a'ㄱ' shape, a'b' shape, a'c' shape, a'ㅁ' shape, a'ㅇ' shape, a'H' shape, and an'I' shape. When implemented, this specification mainly describes the'b' shape.

In addition, the reinforcement member 62 has a cross section extending by a predetermined length in the height direction (H) and the width direction (W).

In the reinforcing member 60 of FIG. 23, a plurality of reinforcing holes j1 extending from the reinforcing member 61 in the height direction H are formed in the longitudinal direction L and D.

It will be described using an exemplary embodiment with respect to the section steel configured using the flange, web, and reinforcement of the present invention as described above.

In the present invention, the H-beam is not formed by simply welding the web and the flange as in the prior art, but the required strength, the form of the load (bending, shear, compression, buckling, etc.), and the large or small or main load between these loads. Accordingly, it is intended to provide a section steel that can achieve an optimal cross-section in consideration of the required cross-sectional shape.

In addition, in order to connect the web and the flange, various types of fastening between the reinforcing hole and the protrusion are basically proposed, and additionally, the protrusion is protruded from the reinforcing hole, and the protruding protrusion and the member in which the reinforcing hole are formed are welded. It is possible to provide a cross section of various shapes while achieving the integral behavior of the flange-web-reinforcement member of the section steel by suggesting that a method of connecting with an adhesive or welding method is used.
