Description

Wale reinforcing structure {REINFORCING STRUCTURE OF WALE}

The present invention relates to a wale reinforcing structure, and more specifically, to a wale reinforcing structure capable of reinforcing vertical and shear forces acting on a wale by means of a brace.

In the case of constructing underground structures such as the basement of a building or the foundation of a bridge, underground excavation work is performed, and at the same time temporary retaining work is performed to prevent soil collapse.

Temporary earth retaining usually installs thumb piles such as H-beams vertically and inserts earth plates in multiple layers between the thumb piles to prevent soil from being pushed into the interior. In addition, in order to support the earth pressure applied to the retaining wall, a wale such as H-beam is installed in the transverse direction on the front of the thumb pile, and a support is installed between the wale on the opposite side to support it.

In this case, a large vertical reaction force is generated by the braces installed in the orthogonal direction at the wale at the point where the braces are installed.

In addition, shear force along with vertical reaction force is generated in the wale installed at the corner position by the brace installed in the oblique direction.

Conventionally, in order to respond to the vertical reaction force caused by the strut, reinforcing steel plates are welded between the upper and lower grooves of the H-beam, that is, between the flanges (see FIG. 1A), or by installing a member capable of adjusting the length. It has been reinforced.

In addition, when a brace is installed in an oblique direction such as a corner, a reinforcing steel plate is welded to the web to respond to shear force along with the vertical force, and at the same time, a reinforcing steel plate is welded between the flanges (see Figs. 1b and 1c) A length-adjustable member has been installed.

However, the reinforcing steel plate welded between the flanges has difficulty in supporting a large vertical force from the beotimbo. In particular, deformation may further progress after the flange between the reinforcing steel plates is deformed. Also, the outer end of the flange is vulnerable to deformation, and this deformation may further progress and break the wale. In addition, the reaction force of the brace may deviate somewhat from the vertical direction due to the non-uniform back earth pressure or the brace installed somewhat inclined unlike the design. In this case, the bearing capacity of the reinforcing steel plate may be reduced. In addition, it takes a lot of time and effort to weld the reinforcing iron plate, and it takes time and effort to remove the reinforcing iron plate after use, and there is a problem in that the wale is damaged in the process of removing the reinforcing iron plate.

In addition, when a length-adjustable reinforcing member is installed, the reinforcing member falls or leaves due to deformation of the ground during use, and it is difficult to ensure the safety of the retaining wall.

In addition, the wale installed at the corner additionally welds a reinforcing steel plate to the web to reinforce the shear. In the case of maintaining it as it is, the iron plate is attached in duplicate when a brace needs to be installed in another location, and accordingly, there is a problem that the wale becomes unnecessarily heavy.

It is a perspective view showing a state in which a reinforcing structure is installed, and FIG. 4B is a perspective view of a wale reinforcing structure according to another example of the present invention.

The wale reinforcing structure according to an example of the present invention includes a pair of support members 20 inserted into a space formed by a pair of flanges and webs, which are upper and lower grooves of an H-shaped wale 10 installed in the horizontal direction. ; and a fixing member 30 preventing the pair of support members 20 from being separated from the wale 10 .

In the case of temporary earth retaining, thumb piles are installed in the vertical direction, and earth plates are stacked between the thumb piles. In addition, on the inside of the thumb pile, an H-shaped wale 10 is installed in the horizontal direction so as to come into contact with the thumb pile. In addition, on the inside of the wale 10, braces 40 are installed between the opposite wale.

The wale 10 includes a pair of flanges spaced apart from each other and a web connecting the pair of flanges. The wale 10 is installed in a horizontal direction with one side (outside) flange in contact with the thumb pile, and a brace 40 is installed on the other side (inside) flange. In addition, the earth pressure acting on the rear surface of the earth plate is transmitted to the support 40 through the thumb pile and the wale 10 and supported.

The support member 20 is inserted into the upper and lower concave portions of the wale 10 at the point where the brace 40 is installed to reinforce the wale 10, thereby increasing the strength of the wale 10 by the concentrated reaction force of the brace 40. Deformation or destruction can be prevented.

The support member 20 includes a plate-shaped first plate 22 closely inserted between the pair of flanges while blocking the outside (upper and lower sides) of the groove, and both ends of the first plate 22. It may be formed in a c-shape including a pair of second plates 23 extending inwardly (toward the web) from the pair of flanges and closely inserted between the flanges.

The U-shaped support member 20 can simultaneously support vertical force and shear force generated in the wale 10 by the reaction force of the brace 40 installed on the inner flange side of the wale 10. That is, it is possible to support both the vertical force by the brace 40 installed in the vertical direction on the wale 10 and the vertical force and shear force by the brace 40 installed in an oblique direction on the wale 10.

In the case of the prior art (see FIG. 1a), the reinforcing steel plate installed in a plate shape between the flange and the flange may deform the flange between the reinforcing steel plate and the reinforcing steel plate when a large reaction force acts, especially toward the outer end of the flange first. After deformation occurs, it can diffuse. In addition, when earth pressure acts in the lateral direction due to deformation of the soil at the back, or when the brace is installed at an angle unlike the design, the reinforcing steel plate has no bearing capacity in the direction of the slope, which can cause structural problems.

On the other hand, the U-shaped support member 20 in which the first plate 22 and the pair of second plates 23 of the present embodiment are integrally formed can well resist the vertical load caused by the beotimbo 40. That is, prevention of deformation of the flange of the wale 10 by the pair of second plates 23, suppression of left-right deformation of the pair of second plates 23 by the first plate 22, and suppression of left-right deformation of the pair of second plates 23 by the first plate 22 ), the support member 20 of this embodiment can well resist the vertical force caused by the strut 40 by preventing deformation of the end of the flange of the wale 10.

In addition, the U-shaped support member 20 in which the first plate 22 and the pair of second plates 23 of the present embodiment are integrally formed is a brace installed in an oblique direction to the wale 10 installed at the corner position ( 40) can resist the shear force well. That is, the U-shaped support member 20 in which the first plate 22 and the pair of second plates 23 are integrally formed forms a closed polygon together with both flanges and webs of the wale 10, thereby forming an oblique direction. It can have an excellent effect on the shear force caused by the load.

The support member 20 may include a first cutout 25 obtained by removing portions of both edges of inner ends of the pair of second plates 23 . In the case of the H-shaped wale 10, a gentle heonchi part is formed at the inner corner where the flange and the web meet, and the first cutout 25 is so that the support member 20 can be well installed despite the heonchi part. do. The first cut-out groove 25 may be about the extent that the heonchi portion can be inserted or larger.

The support member 20 may further include handles provided on the pair of second plates 23 . The handle allows the support member 20 to be easily installed in the concave portion of the furring strip 10 or easily withdrawn from the concave portion of the waling strip 10 . That is, the handle can easily install the support member 20 between the pair of flanges, and is particularly effective in pulling out the support member 20 tightly fitted between the pair of flanges of the wale 10 by earth pressure or the like. can

The handle may be a second cut-out groove 26 obtained by cutting and removing a part of the inner center of the pair of second plates 23 . That is, the handle may be formed by forming a second cutout 26 in which a part of the first cutout 25 is cut and removed in the middle. The cut-out handle has no part that protrudes outward, so the structure can have a simple effect.

The handle may be a separate third plate 27 vertically attached to the outside of the pair of second plates 23 by welding or the like. That is, a separate third plate 27 outside the second plate 23 may be formed by combining both sides by welding or the like.

The handle may be a bent portion 28 that is bent inward or outward by cutting a portion of the pair of second plates 23 . That is, after cutting the second plate 23 in an 11-shape, the bent portion 28 bent inward or outward may be used as a handle.

The bent portion 28 may be simply bent at a right angle or bent at a right angle but may have a round arc shape convex to the inside (the part where the hand closes). The convex round arc shape may be advantageous in withdrawing the support member 20 when it is firmly inserted between the flanges.

The fixing member 30 can simultaneously fix a pair of support members 20 inserted into the grooves on both sides of the H-shaped wale 10. This can facilitate the work by fixing the pair of support members 20 at the same time.

To this end, the fixing member 30 includes a first member 32 installed on the outer side of the wale 10 and extending inward from the upper and lower ends of the first member 32 to the pair of support members 20 A pair of second members 34 installed in contact with the outer side of the first plate 22, and a coupler 36 coupling the second member 34 and the first plate 22 can That is, the fixing member 30 may be formed in a U-shape located on the rear surface and the upper and lower sides of the wale 10 . The fixing member 30 can perfectly prevent the fall or separation of the pair of support members 20 . In addition, there is no need to form an additional through hole in the wale 10, which may be structurally advantageous.

Since the wale sheet 10 is usually installed close to the earth plate, the fixing member 30 is installed on the rear side of the wale sheet 10 in a state where the second member 34 is installed side by side in the longitudinal direction of the wale sheet 10. After inserting the wale 10 into the bowel from the upper or lower side, the second member 34 is rotated to move toward the first plate 22, and then the coupler 36 can be coupled.

The coupling hole 36 may be a bolt that is screwed into a screw hole formed in the first plate 22 after passing through the through hole of the second member 34 .
