Description

BACKGROUND

The present invention relates generally to a wale support module used to mount a wale on an soldier pile during the construction of a retaining wall and, more particularly, to a wale support module enables a groove defined between an soldier pile and a wale to be easily filled by a groove filling block, allows a groove filling block-side wale support or a pile support to pivot in response to the installation angle of an earth anchor to respond appropriately to the inclination of the wale so that the optimal anchoring force of the earth anchor can be exercised, can be removed and reused when a retaining wall is dismantled, and allows the stability of the installation of the wale to be increased by a reverse wale hanger.
A retaining wall is constructed to prevent soil from collapsing during excavation work at a civil engineering construction site. In this case, in order to prevent the retaining wall from collapsing, a strut method or an earth anchor method is usually used selectively. Here, the earth anchor method is a method of supporting earth pressure by tensile force by forming an anchor body on the back of the retaining wall. An anchor uses a tensile member to transmit force to soil or bedrock. In this case, to anchor the head of an earth anchor, a wale is installed on an soldier pile at a side of the retaining wall. However, when soldier piles are irregularly arranged after the soldier piles are constructed, an irregular interval (a groove) is defined between each of the soldier piles and each wale, and thus in order to fill this groove, groove filling steel (an angle iron, a steel plate, or H-shaped steel, etc.) is installed. In this case, it is difficult to standardize the groove filling steel since groove intervals between soldier piles and wales at associated positions are different, and the groove filling steel does not actively respond to the tilted angle of the wale according to the installation direction of the earth anchor, and is difficult to be installed by welding.
Meanwhile, a wale is supported by a wale support bracket installed on the soldier pile of the retaining wall. Accordingly, the wale resists a bending moment and a shear force caused by earth pressure acting on the retaining wall. When the earth anchor is installed on this wale, the earth anchor is installed by having a tilt angle, and to this end, the wale support bracket sometimes requires tilt adjustment. In general, the wale support bracket is installed on the soldier pile of the retaining wall by welding at a site, and then is dismantled and discarded during the removal of the wale. Accordingly, the wale support bracket is not reused, which causes waste of materials and does not help reduce construction costs. Accordingly, technical measures are required for reuse of the wale support bracket.
Technologies related to wales which are the background of the present invention are disclosed in Korean Patent Nos. 10-1677811 and 10-1364227. However, in the technologies, two wales are required to be installed with the rear surfaces of the two wales facing each other, and different spacers are required to be additionally installed on a groove filling support according to a groove interval, and the groove filling support is coupled to the wales by shaft bolts and fixing devices. Due to these additional works, a groove filling work is complicated, and fastening parts are increased, and separate concrete filling and curing time according to the installation of a bellows jack is required.
Technologies related to a wale bracket which are the background of the present invention have been disclosed in Korean Patent Nos. 10-1420374 and 10-1683968. However, in the background technologies, although a solid structure is provided, there is no technical alternative to the reuse of an H-beam wale support bracket to reduce the installation cost of the same, and the support bracket cannot be installed in each of several places depending on the excavation depth of excavation. That is, the wale bracket cannot be installed at each position at which a wale is installed according to depth of a pile. In addition, the angle adjustment of the wale bracket is impossible, so the wale cannot be installed to be inclined for the construction of an earth anchor.

In addition, the wale support module 100 can be dismantled and reused when the wale 20 is removed, so it is possible to reduce waste of materials and construction costs.
As illustrated in FIGS. 1 a to 3, and 7, the wale support module 100 includes a wale support bracket 110 which is detachably installed on the soldier pile 12 located at a position at which the wale 20 is disposed so as to support the wale 20, and a groove filling block 120 or 120′ which is supported by the wale support bracket 110 and fills a groove defined between the wale 20 and the soldier pile 12.
As illustrated in 1 b, the wale support module 100 may further include a reverse wale hanger 130 which is disposed on the upper side of the groove filling block 120 and is detachably installed on the soldier pile 12 so that the installation state of the wale 20 is maintained.
The wale support bracket 110 includes a wale-supporting lower vertical bar 112 which is disposed under the groove filling block 120 and is located to be in contact with the soldier pile 12, a wale-supporting lower support 114 being fixed to the upper end of the wale-supporting lower vertical bar 112 at one end thereof so as to support the lower end of the wale 20, a wale-supporting lower reinforcement bar 116 which is fixed to the lower end of the wale-supporting lower vertical bar 112 at a first end thereof and is fixed to the wale-supporting lower support 114 at a second end thereof, and wale-supporting upper and lower hinge joints 118 a and 118 b which are connected respectively to the upper and lower ends of the wale-supporting lower vertical bar 112 by detachable hinge bolts 117 and are welded to the soldier pile 12. The wale-supporting lower vertical bar 112, the wale-supporting lower support 114, and the wale-supporting lower reinforcement bar 116 are made of L-shaped steel, but are not limited to this type of steel.
Accordingly, the wale support bracket 110 is provided with the wale-supporting upper and lower hinge joints 118 a and 118 b, and the wale-supporting upper and lower hinge joints 118 a and 118 b are welded to the soldier pile 12 so that the wale support bracket 110 can support the wale 20. Later, through the detachment of each of the hinge bolts 117 during the removal of the earth anchor, as illustrated in FIG. 6 , the wale-supporting lower vertical bar 112, the wale-supporting lower support 114, and the wale-supporting lower reinforcement bar 116 can be recovered and reused as the wale support bracket 110.
Here, as illustrated in FIGS. 1 a and 2, a pair of groove filling block guides 115 may be installed on the wale-supporting lower support 114 of the wale support bracket 110 so that the groove filling block guides face each other so as to guide the installation of the groove filling block 120 and to prevent the groove filling block 120 from deviating from an installation position thereof.
In addition, the hinge bolt 117 installed on the wale-supporting lower hinge joint 118 b is preferably inserted through a long hole 1181 into the wale-supporting lower hinge joint 118 b so that the installation angle of the wale-supporting lower support 114 can be adjusted.
As illustrated in FIGS. 1 a, 1 b, and 3 a , the groove filling block 120 of a first type includes: a block body 1210 having a block lower surface 1210 a in surface contact with the support surface of the wale support bracket 110, a block vertical surface 1210 b which is perpendicular to the block lower surface 1210 a and faces the wale 20, and a block inclined surface 1210 c which has a predetermined acute angle to the block lower surface 1210 a and is in surface contact with the soldier pile 12; a plurality of nuts 1220 for groove filling interval adjustment installed on the block vertical surface 1210 b; a groove filling bolt 1230 having a screw shaft 1231 at a first end thereof so that the screw shaft 1231 is screwed to each of the nuts 1220 for groove filling interval adjustment and having a cylindrical pivot 1232 at a second end thereof so that the cylindrical pivot 1232 has a spherical groove 1232 a and a circularly arranged groove 1232 b for rotation manipulation; and a wale support 1240 which is spherically coupled to the spherical groove 1232 a of the cylindrical pivot 1232 and is in surface contact with the wale 20.
Accordingly, the groove filling block 120 of the first type is adjusted in height of the groove filling block 120 protruding from the cylindrical pivot 1232 according to the rotation direction of the groove filling bolt 1230 so that the groove filling block 120 can easily respond to an interval change for filling a groove. In addition, when the installation angle of the wale 20 changes, the wale support 1240 pivots in the spherical groove 1232 a of the groove filling bolt 1230 and is in close contact with the lower surface of the wale 20 so that groove filling is stably realized.
As illustrated in 4 and 7, the groove filling block 120′ of a second type includes: a block body 1210′ having a block lower surface 1210 a′ in surface contact with the support surface of the wale support bracket 110, a block vertical surface 1210 b′ which is perpendicular to the block lower surface 1210 a′ and faces the wale 20, and a screw groove 1210 d′ for groove filling interval adjustment threaded into the block vertical surface 1210 b′; a groove filling bolt 1230′ having a screw shaft 1231′ at a first end thereof so that the screw shaft 1231′ is screwed to the screw groove 1210 d′ for groove filling interval adjustment and having a groove 1232 b′ for rotation manipulation at a second end thereof so that the groove filling bolt 1230′ is in surface contact with the wale 20; a lower pivot bolt 1250′ being screwed to the block body 1210′ so that the lower pivot bolt 1250′ can protrude from the block body 1210′; and a pile support 1260′ which is spherically coupled to the lower pivot bolt 1250′ and is in surface contact with the soldier pile 12.
Accordingly, the groove filling block 120′ of the second type has a protruding amount adjusted by the rotation manipulation of the groove filling bolt 1230′ so that the groove filling block 120′ can respond to a groove filling interval change. In addition, when the installation angle of the wale 20 changes, the pile support 1260′ pivots on the lower pivot bolt 1250′ to be in close contact with the soldier pile 12 so that groove filling can be stably realized.
Here, as illustrated in FIG. 3 b , the groove filling bolt 1230 or 1230′ may further include a fastening nut 1233 so that the adjusted protruding length of the groove filling block is fixed.
Meanwhile, as illustrated in FIG. 5 , the reverse wale hanger 130 includes: a hanger vertical bar 132 which is disposed on the upper side of the groove filling block 120 and is located to be in contact with the soldier pile 12; a hanger support bar 134 which is fixed to a lower end of the hanger vertical bar 132 at one end thereof and is in contact with an upper end of the wale a hanger reinforcement bar 136 which is fixed to an upper end of the hanger vertical bar 132 at a first end thereof and is fixed to the hanger support bar 134 at a second end thereof; and upper and lower hanger hinge joints 138 a and 138 b which are respectively connected to upper end lower ends of the hanger vertical bar 132 by detachable hinge bolts 137 and are welded to the soldier pile 12. The hanger vertical bar 132, the hanger support bar 134, and the hanger reinforcement bar 136 are made of L-shaped steel, but are not limited to this type of steel.
Accordingly, the reverse wale hanger 130 is supported by the wale support bracket 110 and functions to press the wale 20 from an upper side thereof by using the hanger support bar 134, so upward movement of the wale 20 is restrained so that the installation stability of the wale 20 can be secured. In addition, as illustrated in FIG. 6 , the reverse wale hanger 130 can advantageously be reused by dismantling the hanger vertical bar 132 from the upper and lower hinge joints 138 a and 138 b by detaching each of the hinge bolts 137.
Meanwhile, the hinge bolt 137 installed on the upper hanger hinge joint 138 a is inserted through a long hole 1381 into the upper hanger hinge joint 138 a so that the installation angle of the hanger support bar 134 due to the wale 20 may be adjusted.
Accordingly, in the wale support module 100 according to the present invention, even if groove intervals between soldier piles 12 and wales 20 are different, groove filling adjustment can be performed by the groove filling bolt 1230 or 1230′ of the groove filling block 120 or 120′. In addition, the wale support 1240 or the pile support 1260′ actively pivots according to the tilted angle of the wale 20 according to the installation direction of the earth anchor 5 so that the wale 20 can be stably supported.
In addition, during the removal of the wale 20, the wale support bracket 110 can be removed and reused while the wale-supporting upper and lower hinge joints 118 a and 118 b are left on the soldier pile 12, so it is possible to reduce the cost of construction by reducing the waste of materials.
Furthermore, when the reverse wale hanger 130 is additionally installed, the wale 20 is more stably installed, and thus the earth anchor 5 can exercise optimal anchoring force, and the reverse wale hanger 130 is also reused while only the upper and lower hinge joints 138 a and 138 b are left, so it is possible to reduce construction costs.
According to the wale support module filling a non-welding groove and being capable of being reused according to the present invention, even if groove intervals between soldier piles and wales are different from each other, groove filling adjustment is easily performed by the groove filling bolt of the groove filling block; according to the tilted angle of the wale according to the installation direction of the earth anchor, the wale support or the pile support actively pivots so that the wale can be stably supported; and during the removal of the wale, the wale support bracket can be removed and reused while only the wale-supporting upper and lower hinge joints are left on the soldier pile so that the cost of construction can be reduced by reducing the waste of materials. In addition, when the reverse wale hanger is additionally installed, the wale is more stably installed, and thus the earth anchor can exercise optimal anchoring force, and the reverse wale hanger can also be removed and reused while only hinge joints are left.
