Description

Technology Field

[0001] The present invention relates to a tie beam groove filling structure, and more specifically, to a tie beam groove filling structure for filling a groove between a retaining wall and a tie beam, which is improved to be movable in the left and right directions and the front and rear directions from the top of the tie beam, thereby allowing the groove occurring between the retaining wall and the tie beam to be easily filled regardless of the dimensions of the retaining wall in the form of an H-beam or sheet pile, and enabling the groove filling work to be performed simply and quickly.

[0002] The present invention relates to a tie beam groove filling structure with an improved structure that can transmit the earth pressure of the earth retaining wall to the tie beam side regardless of the contact angle of the rotating plate contacting the front surface of the earth retaining wall by using a rotating plate that can rotate as it comes into contact with the earth retaining wall. Background Technology

[0003] Generally, retaining walls are constructed at civil engineering and construction sites to prevent soil and other materials from collapsing during excavation work.

[0004] In order to prevent the retaining wall from collapsing, the strut method or the earth anchor method is typically used selectively. The earth anchor method is a technique that supports earth pressure by tensile force by forming an anchor body on the back of the retaining wall; the anchor uses a tension member to transmit the force into the soil or bedrock. At this time, a tie beam is installed on the king pile on the retaining wall side to anchor the head of the earth anchor.

[0005] However, when the king piles are arranged irregularly after construction, irregular gaps (grooves) occur between the king piles and the tie beams, so groove-filling steel (angles, steel plates, H-shaped steel, etc.) is installed to fill these grooves.

[0006] In this case, the groove-filling steel is difficult to standardize because the groove spacing between the king pile and the tie beam at the corresponding location varies; furthermore, it cannot actively respond to the tilted angle of the tie beam depending on the installation direction of the earth anchor, and there is a problem requiring welding installation work.

[0007] As disclosed in Korean Registered Patent Publication No. 10-1677811, "Steel structure of a single earth anchor tie beam for earth retaining support and method of construction thereof" (Registration date: 2016.11.14), a tie beam is constructed using steel materials facing each other, and then a connecting joint plate for maintaining spacing as a substitute for a stiffener, a pressure plate, an upper and lower fixing device for the anchor tensioning part, an upper and lower fixing device for the shaft support part, and a mounting bracket combined with a shaft bolt and a spacer are assembled to form a removable earth anchor tie beam structure for earth retaining support that can be reused. Through this, the angle bracket and the steel material for the tie beam can be reused, and the angle bracket and the tie beam can be easily assembled and constructed.

[0008] As another prior art related to existing tie beam groove filling, as disclosed in Korean Registered Patent Publication No. 10-2077421 "Tie beam having groove-filling bolt and method of construction thereof" (Registration date: 2020.02.07), it relates to a tie beam having groove-filling bolt and a method of construction thereof in which a groove formed between a king pile and a tie beam during the construction of an earth retaining wall can be easily filled with a groove-filling bolt installed on the tie beam, and a spherical connection is applied to the support structure of the groove-filling bolt so that the tie beam can be installed to optimally exert anchor force corresponding to the installation angle of the earth anchor.

[0009] However, the existing tie beam groove filling structure can be applied on-site because the left and right spacing and depth of the grooves vary depending on the angle dimensions of the tie beam and the retaining wall, but there are safety-related issues.

[0010] In addition, existing retaining walls can be constructed by connecting H-beams or multiple sheet piles. When using sheet piles, individual piles must be connected sequentially, which means multiple sheet piles cannot be constructed simultaneously. Consequently, groove filling work must be performed while connecting each sheet pile. Since the structure is difficult to maintain horizontality when viewed from a plan due to the load pressure of the soil on the temporary retaining wall or the ground structure, the groove depth between the tie beam and the retaining wall inevitably varies depending on the section of the retaining wall. Consequently, each groove cannot be standardized during the groove filling work, which has the disadvantage of requiring a long working time. Prior art literature

[0011] Korean Registered Patent Publication No. 10-1677811 "Steel structure of a single earth anchor tie beam for earth retaining support and method of construction thereof" (Registration Date: Nov. 14, 2016) Korean Registered Patent Publication No. 10-2077421 "Tie beam having groove-filling bolts and method of construction thereof" (Registration Date: Feb. 07, 2020) The problem to be solved

[0012] The present invention was created to solve the aforementioned problems, and its purpose is to provide a tie beam groove filling structure with an improved structure that allows the groove between the earth retaining wall and the tie beam to be easily filled regardless of the dimensions of the earth retaining wall in the form of an H-beam or sheet pile, and enables the groove filling work to be performed simply and quickly, by improving the tie beam groove filling structure to be movable in the left and right directions and the front and rear directions from the top of the tie beam.

[0013] Another objective of the present invention is to provide a tie beam groove filling structure with an improved structure that can transmit the earth pressure of the earth retaining wall to the tie beam side regardless of the contact angle of the rotating plate contacting the front surface of the earth retaining wall by using a rotating plate that can rotate as it comes into contact with the earth retaining wall. means of solving the problem

[0014] The present invention for achieving the above-mentioned purpose is characterized by comprising: a movable block positioned to be movable in the left and right directions by being guided by a moving guide means on the upper side of a tie beam to fill a groove formed between a retaining wall and a tie beam; a support casing positioned on the upper side of the movable block and having an opening formed on one side facing the retaining wall; a movable plate received inside the support casing and movable toward the retaining wall by a moving means; and a rotating plate having one end contacted to be linked with the movement of the movable plate, one end moved to contact the retaining wall through the opening, and is positioned to be rotatable by a rotating means when in contact with the retaining wall, and rotated to the left or right depending on the angle of contact between one end and the retaining wall.

[0015] The above-described rotation means comprises an elongated hole drilled longitudinally toward the earth retaining wall on the upper surface of the support casing, a guide member that enters into the interior of the support casing through the elongated hole and is connected to the other side of the rotation plate to guide the longitudinal movement of the rotation plate, a rounded portion formed roundly on the other end of the rotation plate, and a support groove formed roundly on one edge of the movable plate so as not to interfere with the rotation of the rounded portion, with a part of the rounded portion in contact with it.

[0016] The above moving means is equipped with a moving bolt that is fastened to a plurality of fastening holes on the other side of the support casing, and whose end contacts the other side of the moving plate, thereby moving the moving plate toward the earth retaining wall side during rotational movement.

[0017] The above moving means further comprises an entry hole formed by perforating the right side of the support casing to communicate with the outside, and a support block that is inserted into the interior of the support casing through the entry hole and interposed between the moving bolt and the other side of the moving plate.

[0018] The above-mentioned rotating plate has one end formed in a straight shape that can contact the earth retaining wall, and is connected to a guide member that can move in the forward and backward directions along an elongated hole formed on the upper surface of the support casing, at a rounded portion formed at the other end that contacts the movable plate.

[0019] The above movement guide means is provided with a guide rail formed to protrude upwardly from the upper edges of the above-mentioned band and guides the left and right movement of the above-mentioned movement block seated on the upper part of the above-mentioned band, and the above-mentioned movement block is composed of a lower block guided by the guide rail and an upper block formed with a stepped edge on the upper part of the lower block and having the above-mentioned support casing coupled thereto. Effects of the invention

[0020] The present invention has the useful advantage of easily accommodating variations in the spacing of each groove of the sheet piles constituting the earth retaining wall, as the moving block slides in the left and right directions from the upper part of the tie beam to fill the grooves that occur between the tie beam and the earth retaining wall, and can transmit earth pressure transmitted through the earth retaining wall to the tie beam side regardless of the contact angle of the rotating plate with respect to the front surface of the earth retaining wall.

[0021] The present invention has the useful advantage of allowing the groove filling work to be easily performed regardless of the angle when performing groove filling work on a retaining wall and a tie beam composed of sheet piles, as the movable block can move left and right along the upper part of the tie beam and the rotating plate can move forward and backward toward the retaining wall, and thus allows left and right and forward and backward movement.

[0022] In addition, the present invention has the advantage of enabling the movable plate and the rotating plate to be moved toward the retaining wall by a simple bolt fastening method, as the movable bolt is tightened in the direction in which the tightening force is applied when the movable block arrives at the groove portion of the retaining wall and the tie beam, and the end of the movable bolt contacts the other end of the movable plate and pushes the movable plate toward the retaining wall.

[0023] In addition, the present invention has the advantage of maintaining durability against earth pressure loads by interposing at least one support block in the gap between the movable plate and the inner surface of the support casing, thereby allowing the movable plate's travel distance to be compensated by the support block without the need to form a long movable bolt, thus reducing the length of the movable bolt.

[0025] In describing the present invention, if it is determined that a detailed description of related prior art or configurations could unnecessarily obscure the essence of the invention, such detailed description will be omitted. Furthermore, the terms described below are defined considering their functions in the present invention and may vary depending on the user's intent or convention. Therefore, their definitions should be based on the content throughout this specification. Additionally, the term "comprising" a component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0026] The earth retaining wall of the present invention may be composed of H-beams or sheet piles, but here, a connected sheet pile structure will be described as an example.

[0027] A groove-filling structure for a tie beam according to the present invention, described with reference to FIGS. 1 to 7, comprises: a movable block (100) positioned to be movable in the left and right directions by being guided by a moving guide means on the upper side of the tie beam (50) to fill a groove (15) formed between the earth retaining wall (10) and the tie beam (50); a support casing (200) positioned on the upper side of the movable block (100) and having an opening (210) formed on one side facing the earth retaining wall (10) that is open; and a movable plate (310) received inside the support casing (200) and movable toward the earth retaining wall (10) by a moving means. The device comprises a rotating plate (320) having one end contacted to be synchronized with the movement of the moving plate (310), and one end moved to be in contact with the earth retaining wall (10) through the opening (210), and is arranged to be rotatable by a rotation means when in contact with the earth retaining wall (10), and rotated to the left or right depending on the contact angle between the one end and the earth retaining wall (10).

[0028] Referring to FIGS. 1 and 2, as the tie beam (50) is attached to the front surface of the earth retaining wall (10), a groove (15) is formed in the tie beam (50) and the earth retaining wall (10), and to fill the groove (15), a movable block (100) is seated on the upper side of the tie beam (50) so as to be movable in the left and right directions relative to the earth retaining wall (10).

[0029] To this end, the above movement guide means is provided with a guide rail (55) formed to protrude upward on both upper edges of the above band (50) to guide the left and right movement of the above movement block (100) which is seated on the upper part of the above band (50).

[0030] As shown in FIGS. 1 and 2, the above-described moving block (100) is formed in the shape of a rectangular block that slides in the left and right directions along the guide rail (55) and is composed of a lower block (110) that is guided by the guide rail (55) and an upper block (120) that is formed with a stepped shape on the upper side of the lower block (110) and has the support casing (200) coupled to the upper side.

[0031] More preferably, the moving block (100) may be further provided with bearing rollers (not shown) on one side and the other side of the moving block (100) respectively so that it can slide along the guide rail (55).

[0032] That is, the above-mentioned moving block (100) has a stepped upper block (120) formed on the upper side of the lower block (110), and a support casing (200) is coupled to the upper side of the upper block (120), so that the moving plate (310) and the rotating plate (320) housed within the support casing (200) do not interfere with the guide rail (55) even when they are moved toward the earth retaining wall (10) by a moving means.

[0033] The support casing (200) is formed in the shape of a rectangular casing, and a moving plate (310) and a rotating plate (320) are introduced into the interior of the support casing (200) through an opening (210) formed on one side.

[0034] In addition, as shown in FIG. 3, the support casing (200) has a plurality of fastening holes (410) formed on the other side to which a moving bolt (420) is fastened, and an entry hole (220) formed on the right or left side to allow a support block (500) to enter the interior of the support casing (200).

[0035] Here, the entry hole (220) is described as being formed on the right side of the support casing (200) as an example, but is not limited thereto.

[0036] As illustrated in FIGS. 4 and 5, the above-described rotation means comprises an elongated hole (205) that is drilled longitudinally toward the earth retaining wall (10) on the upper surface of the support casing (200), a guide member (330) that enters the interior of the support casing (200) through the elongated hole (205) and is connected to the other side of the rotation plate (320) to guide the longitudinal movement of the rotation plate (320), a rounded portion (325) formed roundly on the other side end of the rotation plate (320), and a support groove portion (315) formed roundly on one side edge of the movable plate (310) so as to have a curvature identical or similar to the curvature of the rounded portion (325) so as to be in contact with a part of the rounded portion (325) and not interfere when the rounded portion (325) rotates.

[0037] The above-mentioned elongated hole (205) is connected to a guide member (330) that is connected to the rotating plate (320) through it.

[0038] The guide member (330) performs the function of guiding the movement of the rotating plate (320) along the elongated hole (205) and has a structure in which its end is coupled to the rotating plate (320).

[0039] At this time, the lower end of the guide member (330) is coupled to the center of curvature of the round part (325), and the upper end penetrates the elongated hole (205) and protrudes upward, becoming the center of rotation of the rotating plate (320) and guiding the movement of the rotating plate (320).

[0040] The curvature of the round portion (325) of the rotating plate (320) is formed to be the same or similar to the curvature of the support groove portion (315), so that the end edge of the round portion (325) contacts the support groove portion (315), and when the end edge of the rotating plate (320) contacts the earth retaining wall (10), the rotating plate (320) has a structure in which it rotates according to the slope of the earth retaining wall (10) when viewed from a flat plane.

[0041] The above-mentioned rotating plate (320) has a structure that is linked to the movement of the moving plate (310) because the round portion (325) rotates within the support groove portion (315) of the moving plate (310).

[0042] The above moving means is equipped with a moving bolt (420) that is fastened to a plurality of fastening holes (410) on the other side of the support casing (200), and whose end contacts the other side of the moving plate (310) to move the moving plate (310) toward the earth retaining wall (10) during rotational movement.

[0043] The above moving means further comprises an entry hole (220) formed by perforating the right side of the support casing (200) to communicate with the outside, and a support block (500) that is inserted into the interior of the support casing (200) through the entry hole (220) and is interposed between the moving bolt (420) and the other side of the moving plate (310).

[0044] The above support block (500) is formed in the shape of a rectangular block.

[0045] The present invention, having such a configuration, allows a moving block (100) to slide in the left or right direction along a guide rail (55) provided on the upper part of a tie beam (50), and moves each moving block (100) at each groove (15) formed between the tie beam (50) and the earth retaining wall (10).

[0046] Subsequently, as shown in FIG. 6, when each movable block (100) is positioned in the groove (15) area, the movable plate (310) is pushed toward the retaining wall (10) using the movable bolt (420), and as shown in FIG. 7, a plurality of support blocks (500) are interposed between the movable bolt (420) and the movable plate (310).

[0047] As shown in FIG. 5, the above-mentioned moving bolt (420) is fastened to the fastening hole (410) and its end contacts the moving plate (310) or the support block (500). The moving plate (310) is pushed toward the earth retaining wall (10) so that the edge of one end of the moving plate (310) contacts the earth retaining wall (10) in which the groove (15) is formed, and the moving bolt (420) is then moved to the outside of the other side of the support casing (200) by rotating it in the opposite direction to the fastening direction of the moving bolt (420), thereby forming a gap between the moving plate (310) and the support casing (200) through which the support block (500) can enter.

[0048] As shown in FIGS. 5 and 7, the support block (500) is pushed into the gap through the entry hole (220), and the support block (500) is pushed out by the fastening operation of the moving bolt (420) and the fastening hole (410), thereby moving the moving plate (310) and the rotating block toward the retaining wall (10).

[0049] The above support block (500) is inserted into the interior of the support casing (200) through the entry hole (220), and the length of the rotation plate (320) being pulled out toward the retaining wall (10) through the opening (210) can be adjusted according to the number of the above support blocks (500).

[0050] As shown in FIGS. 5 and 7, when the moving bolt (420) is tightened, the pressure pushed through the support block (500) is transmitted to the moving plate (310), and as the moving plate (310) moves forward (towards the retaining wall (10)), the rotating plate (320) moves in conjunction with it.

[0051] At this time, the guide member (330) can move in the forward and backward directions within the elongated hole (205) formed on the upper surface of the support casing (200), thereby guiding the movement of the rotation plate (320).

[0052] One end edge of the rotating plate (320) contacts the front surface of the earth retaining wall (10), and depending on whether the front surface of the earth retaining wall (10) is positioned to have a horizontal or inclined slope relative to a flat plane, the one end edge of the rotating plate (320) moves horizontally or rotates.

[0053] When the rotating plate (320) is rotated as one end edge comes into contact with the earth retaining wall (10), the round portion (325) formed on the other end rotates within the support groove (315) of the moving plate (310), and even when the round portion (325) rotates within the support groove (315), the contact state between the rotating plate (320) and the moving plate (310) can be maintained.

[0054] Accordingly, the rotating plate (320) and the moving plate (310) act as structures that fill the groove (15) between the aforementioned tie beam (50) and the earth retaining wall (10), and transmit earth pressure to the tie beam (50) side, thereby enabling the reinforcing function of the earth retaining wall (10).

[0055] Accordingly, the present invention has the useful advantage of being able to easily respond even if the spacing of each groove (15) of the sheet pile constituting the earth retaining wall (10) varies, as the moving block (100) slides in the left and right directions from the upper part of the tie beam (50) to fill the groove (15) that occurs between the tie beam (50) and the earth retaining wall (10), and can transmit the earth pressure transmitted through the earth retaining wall (10) to the tie beam (50) side regardless of the contact angle of the rotating plate (320) with respect to the front surface of the earth retaining wall (10).

[0056] The present invention has the useful advantage that the groove filling work can be easily performed regardless of the angle when the groove filling work is performed on the retaining wall (10) and the retaining wall (50) composed of sheet piles, because the moving block (100) can move left and right along the upper part of the retaining wall (50) and the rotating plate (320) can move forward and backward toward the retaining wall (10), and thus left and right and forward and backward movement is possible.

[0057] In addition, the present invention has the advantage of being able to quickly perform the groove (15) filling work by allowing the movable plate (310) and the rotating plate (320) to be moved toward the retaining wall (10) by a simple bolt fastening method when the movable block (100) arrives at the groove (15) of the retaining wall (10) and the movable bolt (420) is tightened in the direction in which the tightening force is applied, so that the end of the movable bolt (420) contacts the other end of the movable plate (310) and pushes the movable plate (310) toward the retaining wall (10).

[0058] In addition, the present invention has the advantage of maintaining durability against earth pressure loads by interposing at least one support block (500) in the gap between the movable plate (310) and the inner surface of the support casing (200), thereby allowing the movable plate (310) to be compensated for by the support block (500) without the need to form a long movable bolt (420), thus reducing the length of the movable bolt (420).

[0059] As such, it goes without saying that specific embodiments have been described in the detailed description of the present invention. Therefore, the scope of the present invention should not be limited to the embodiments described above, but should be defined by the claims set forth below as well as equivalents thereof.

[0060] In other words, the present invention as described above is not limited to the specific preferred embodiments described above, and anyone with ordinary knowledge in the technical field to which the invention pertains can make various modifications without departing from the essence of the invention claimed in the claims, and such modifications will be within the scope of the claims.
