Description

Bearing-type diagonal connecting member for steel pipe strut and diagonal jointing structure of furring strip and steel pipe strut using approx}

The present invention relates to a member for joining steel pipe braces inclined at a certain angle to the strip of the retaining wall, in particular, the joint angle of the strip and steel pipe braces can be adjusted freely, even if the change of the joining angle due to earth pressure during construction Achieve inclined joints of the steel pipe brace for the earth wall and the joints of which the connecting bolts function only as a pivot shaft and do not support shear force for load transfer and load transfer is made by a separately installed shim type connecting plate. The present invention relates to an inclined joint structure of a strip and a steel pipe brace using a member.

Underground excavation is mostly occupied by civil engineering works for the construction of subways and underground joint zones, as well as the construction of large buildings in urban areas, which is inevitable to increase the utility of limited available land. It is expected.

The wall is a temporary structure for the purpose of resisting the lateral pressure such as earth pressure and water pressure that occur during underground excavation, but recently, excavation work is frequently done in the downtown area, so it is constructed for the purpose of ground subsidence or building protection. The purpose of use is diversified.

The retaining wall can be classified into various types according to the type of the wall and the supporting structure for supporting the wall. The wall consists of thumb pile, earth plate, board pile, column pile, underground continuous wall, etc., and the supporting structure is composed of bracing, raker, anchor, and soil nailing.

Construction of the retaining wall, which is composed of the thumb pile and the earth plate and supported by the brace, is usually carried out according to the following procedure.

First, as a wall forming process, the thumb pile is installed in the longitudinal direction along the inner wall surface where the earthen construction is required, and a earth plate is inserted between these thumb piles to complete the wall. Subsequently, in order to support the wall while the excavation is proceeding, the belt is installed in the horizontal direction, that is, the direction perpendicular to the thumb pile, and a support beam is installed between the bands to complete the retaining wall.

However, in some cases, it is necessary to install a brace between the opposite walls and at the same time additional braces for the edges of the walls, and the braces installed at the corners are joined at a certain angle to the band.

That is, in order to support the edge portion of the wall, the brace is additionally coupled to the band at the edge of the wall, but the brace and the edge portion is coupled to form a predetermined angle so that the brace cannot be constructed directly on the edge of the wall. Therefore, after connecting the member called the stiffened steel formed to have an angle in accordance with the corner portion of the wall of the construction site where the brace is constructed, the stiffened steel is joined at the corner of the wall after connecting the brace with the brace via a connecting means such as a jack.

That is, the stiffened steel and the brace assembly coupled thereto are coupled to the band around the edge of the wall at an angle, typically 45 degrees, to prevent adjacent walls from collapsing by transferring loads to the assembly in opposite directions. .

In order to install the brace with an inclined angle as described above, an inclined joint member (commonly called an 'angle') is used.

Looking at the structure of a conventional angle, the two angle brackets are connected through a pivot axis in the middle. Therefore, the two angle brackets are relatively tilt angle adjustment through the pivot axis (connection bolt).

However, when the compressive force acts on the two angle brackets by the lateral pressure, the pivot shaft transmits the load while supporting the shear force. Therefore, there is a risk that excessive shear force may occur on the pivot axis, and accordingly, excessive deformation occurs or shear failure on the pivot axis may cause the collet to escape, resulting in the collapse of the retaining wall.

Therefore, the present invention is to solve the above problems, the pressure-sensitive inclined joint member of the steel pipe brace for earth wall wall that can prevent excessive deformation or destruction of the pivot axis by preventing the side pressure acting on the wall does not act on the pivot axis of the angle And it aims to provide an inclined joint structure of the strip and steel pipe brace using this joint member.

Therefore, the structure of any one pivot bracket 20 will be described with reference to FIG. 1.

The pivot bracket 20 is made of steel. The pivot bracket 20 has a support plate 22 having a constant thickness, and a connecting plate 24 connected to one side of the support plate 22 at right angles, and having a convex curved surface 25 formed at the pivot hole 24a and the front end thereof. ) And a load transfer plate 36 arranged on one side of the connecting plate 24 to form a concave curved surface 35 having the same curvature as the convex curved surface 25 at the distal end thereof.

The support plate 22 is connected to the strip 1 or the steel pipe-shaped brace 2 depending on the installation direction. In this embodiment, the support plate 22 is configured in a circular shape, but may also be configured in a shape corresponding to the same size and shape according to the end shape of the brace 2. In the present embodiment, the one side support plate 22 has a plurality of bolt fastening holes 22a circumferentially perforated to be connected by the threaded member 1 and the bolt and nut screwed together, and the other support plate 22 'is also a steel pipe-shaped brace.

In this embodiment, the connecting member (2a) is mounted to the end of the steel pipe-shaped support (2) by welding, and the connecting member (2a) is configured to be assembled by the other support plate 22 'and bolt coupling, but the present invention is a connecting member The other side of the support plate 22 'may be directly welded to the steel pipe-shaped brace 2 without using.

The connecting plate 24 is installed in the direction perpendicular to the support plate 22. In this case, the connecting plate 24 may be integrally formed on the support plate 22 or may be manufactured separately and joined by welding.

The convex curved surface 25 is formed by the same radius R centering around the pivot hole 24a here, and the concave curved surface 35 has the same curvature as the convex curved surface 25. As shown in FIG. Therefore, as shown in FIG. 3, when the pair of pivot brackets 20 and 20 'are disposed to face each other, the convex curved surface 25 on one side is slidably in contact with the concave curved surface 35' on the other side, and at the same time, the convex on the other side is convex. The curved surface 25 'is in sliding contact with the concave curved surface 35 on one side. Therefore, the convex curved surface 25 on one side, the concave curved surface 35 'on the other side, and the concave curved surface 35' on the other side and the convex curved surface 25 'on the other side are in sliding contact with each other at the same curvature.

In the present embodiment, the length of the convex curved surface 25 is formed in a section forming 180 degrees from the center point of the pivot hole 24a, and the concave curved surface 35 is configured to be shorter than the length of the convex curved surface 25.

However, the present invention is not limited to the length of the convex surface 25 and the concave curved surface 35 is illustrated, the convex surface 25 and the concave curved surface 35 in the same curvature surface facing each other and at this time If the surface rotates while sliding the other surface, a relative rotation angle is formed. In this case, the relative rotation angle of the pair of bracket brackets 20 may be determined within 90 degrees.

The pair of pivot brackets 20 and 20 'configured as described above are pivotally connected through connecting means penetrating the pivot holes 24a and 24'a which are disposed to face each other as shown in FIGS. 3 and 4. do. At this time, the diameter of the pivot holes 24a, 24'a is formed larger than the diameter of the connecting bolt 40.

The operation of the first embodiment configured as described above will be described.

When the corner inclination angle θ1 is required to support the retaining wall as shown in FIG. 3B, the acupressure type inclined joint member 10 is used. At this time, the acupressure type inclined joint member 10 is already installed and used at the end of the steel pipe-shaped support (2).

Therefore, it is possible to support the retaining wall by connecting the acupressure type inclined joint member 10 suspended in the strong brace 2 to the strip 1.

Therefore, the pivot bracket 20 on one side is connected to the belt 1 and the pivot bracket 20 'on the other side is connected to the brace 2.

In this case, the pair of pivot brackets 20 and 20 'around the connecting bolt 40 forms the required inclination angle θ1.

Then, when the side pressure acting on the retaining wall is transmitted to the pair of pivot brackets 20 and 20 ', the pair of pivot brackets 20 and 20' are two places, that is, the convex curved surface 25 and the concave curved surface 35 'and In the surface contact between the concave curved surface 35 and the convex spherical surface 25 ', the load transfer plate 36' at the connecting plate 24 or the load transfer plate at the connecting plate 24 'without passing through the connecting bolt 40. 36). This is possible because the diameter of the pivot holes 24a and 24'a is larger than the diameter of the connecting bolt 40. Here, the connection bolt 40 contributes only to rotation and does not receive any load.

Therefore, since the side pressure received by the azimuth-type inclined joint member 10 from the strip 1 is not transmitted to the connecting bolt 40, the shearing force is not generated in the connecting bolt 40, which causes breakage of the connecting bolt 40. It can prevent.

As described above, the present invention enables the angle adjustment of the pair of pivot brackets 20 and 20 'by sliding surface contact between the convex curved surface 25 and the concave curved surface 35' having the same curvature, and at the same time the transfer of load Since the connecting bolt 40 does not act as a shearing force, so the phenomenon that the support beam 2 is separated from the acupressure type inclined joining member 10 does not occur, thereby greatly improving the construction safety of the retaining wall.

≪ Embodiment 2 >

Acupressure-type inclined joint member 10 'according to the second embodiment is the first pivot bracket 120 and the second pivot bracket 130 and connecting means for connecting the brackets 120, 130 as shown in Figs. It consists of.

The first pivot bracket 120 is made of steel. The first pivot bracket 120 is provided side by side on the first support plate 122 and the first support plate 122 having a constant thickness and the first pivot holes 124a and 124a on the same straight line, respectively. A pair of first connecting plates 124 and 124 having a concave curved surface 127 at a distal end thereof, and a load transfer plate 126 positioned between the first connecting plates 124 and 124 and connected to the first supporting plate 122 at a right angle. )

The first support plate 122 is configured in a circular shape in the present embodiment, but the embodiment is not limited thereto. In the first support plate 122, a plurality of bolt fastening holes 122a are formed at the periphery for the connection with the strip 1.

The pair of first connecting plates 124 and 124 are installed at right angles to the first supporting plate 122 at regular intervals. In this case, the pair of first connecting plates 124 and 124 may be integrally formed on the first supporting plate 122 or may be manufactured separately and joined by welding.

The second pivot bracket 130 may be made of steel. The second pivot bracket 130 is positioned between the second support plate 132 having a constant thickness and a pair of first connection plates 124 and 124 connected to one side of the second support plate 132 at right angles. And the second connecting plate 134 and the second connecting plate 134 which are in surface contact with the convex curved surface 137 having the same curvature to the second pivot hole 134a and the concave curved surface 127, respectively. The pair of load transfer plates 136 and 136 are installed on the second supporting plate 132 and are in sliding contact with the first connecting plates 124 and 124, respectively.

The second support plate 132 has a circular configuration in order to connect to the steel pipe-shaped brace 2 in the present embodiment, but may also be configured in a square according to the cross-sectional shape of the brace. In the present embodiment, the second support plate 132 has a plurality of bolt fastening holes 132a in the circumferential direction in order to be fastened with the connection member 2a welded to the end of the brace 2 by bolts. However, in the present invention, the second support plate 132 may be directly welded to the end portion of the steel tubular support 2 without the connecting member 2a. In this case, the second connection plate 134 and the load transfer plates 136 and 136 may be integrally formed on the second support plate 132 or separately manufactured and then joined by welding.

The thickness of the second connecting plate 134 may be configured to be equal to or smaller than a gap formed between the pair of first connecting plates 124 and 124. The thickness of the load transfer plates 136 and 136 is configured to be the same as the thickness of the first connecting plate 124.

The convex curved surface 125 is formed in the first connecting plate 124 by the same radius R with the first pivot hole 124a as the center point, and the load transmitting plate 136 is the same as the convex curved surface 125. A concave curved surface 135 having a curvature is formed. Therefore, these convex curved surfaces 125 and concave curved surfaces 135 are in contact with each other at the same curvature after assembling as shown in FIGS. 5 and 7.

In the present embodiment, the length of the convex curved surface 125 is formed in a section forming 180 degrees from the center point of the pivot hole 124a, and the concave curved surface 135 is configured to be shorter than the length of the convex curved surface 125.

However, the present invention is not limited to the length of the convex surface 125 and the concave curved surface 135 is illustrated, the convex surface 125 and the concave curved surface 135 in the same curvature surface surface contact with each other at this time It is enough if the relative rotation angle is formed by sliding the other curved surface. In this case, a relative rotation angle of the first pivot bracket 120 and the second pivot bracket 130 may be determined within 90 degrees.

The connecting means connects the first pivot bracket 120 and the second pivot bracket 130 through the first pivot holes 124a and 124a and the second pivot hole 134a. In the present embodiment, the connecting means is composed of a connecting bolt 140 and the nut 142, but the connecting means applied to the present invention may be manufactured in the form of a shaft or pin.

Here, the diameters of the first pivot holes 124a and 124a and the second pivot holes 134a are all the same, and these holes are formed larger than the diameter of the connection bolt 140.

The operation of the second embodiment configured as described above will be described.

The acupressure type inclined joint member 10 ′ of the second embodiment is already installed and used at one end of the steel pipe-shaped brace 2. Therefore, one end of the steel pipe-shaped brace 2 is acupressure-type inclined bonding member (10 ') is suspended.

Therefore, as shown in (b) of FIG. 7, the first pivot bracket 120 of one side is connected to the band 1, and the second pivot bracket 130 of the other side is connected to the brace 2 as shown in FIG. .

In this case, the first pivot bracket 120 and the second pivot bracket 130 around the connecting bolt 140 form the required inclination angle θ1. Here, the connection bolt 140 contributes only to rotation and does not receive any load.

Since the side pressure acting on the retaining wall is convex surface 125 and the concave surface (from the first pivot bracket 120 to the second pivot bracket 130 or from the second pivot bracket 130 to the first pivot bracket 120) It is transferred from the first connecting plate 124 to the load transfer plate 136 or from the load transfer plate 136 to the first connecting plate 124 in surface contact with the 135. In addition, the surface of the concave curved surface 127 and the convex curved surface 137 is transferred from the load transfer plate 126 to the second connecting plate 134. This is possible because the diameters of the first pivot holes 124a and 124a and the second pivot holes 134a are larger than the diameter of the connecting bolt 140.

Therefore, since the side pressure is not transmitted to the connecting bolt 140, the shear force is not generated in the connecting bolt 140, thereby preventing the breaking of the connecting bolt 140.

As described above, the present invention is capable of adjusting the angle of the first pivot bracket 120 and the second pivot bracket 130 by sliding contact between the convex curved surfaces 125 and 137 and the concave curved surfaces 135 and 127 formed by a constant radius of curvature. Since the shear force is not applied to the connecting means connecting the first pivot bracket 120 and the second pivot bracket 130 due to the transfer of load, excessive deformation or breakage does not occur in the brace so that the acupressure type inclined joint member 10 side Since the separation phenomenon does not occur in the construction wall construction safety is greatly improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention . The invention is not limited by these variations and modifications, but is only limited by the scope of the appended claims.
