Description

Technical Field

[0001] In the field of bridge construction technology, this utility model relates to a layered rear anchor structure. Background Technology

[0002] The cantilever casting method is a construction method for bridges that uses a mobile formwork as a working platform to symmetrically cast concrete beams in segments on both sides of the pier, applying prestress to each segment to form a continuous beam structure. This method requires first erecting the formwork on the completed No. 1 block, and then completing the concrete pouring on the formwork system. The layered anchorage structure is located at the tail end of the main longitudinal beam, which shifts the overall center of gravity of the formwork rearward, improving its overall overturning resistance.

[0003] Patent 202211294918.2 discloses a layered rear anchor structure, which divides the rear anchor structure into an upper anchor and a lower anchor, connected by a bolt. This method solves the technical problem of the rear anchor structure being located above the main longitudinal beam, resulting in a long and inconvenient lifting rod, thus reducing the length of the lifting rod. However, this structure has the following problems: First, during installation, the anchor rod needs to pass downwards from above the main longitudinal beam through a hole in the main longitudinal beam, then through the lower anchor, and finally be locked with a nut. The long length of the bolt makes this operation extremely inconvenient. Similarly, the same problem arises when removing the bolt. Second, the position of the bolt is limited by the position of the hole in the main longitudinal beam, making it impossible to flexibly adjust according to the actual site conditions.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Example

[0024] This embodiment provides a layered rear anchor structure 100, as shown in the reference... Figure 1 As shown, it includes a first anchor 120 located above the main longitudinal beam 110 and a second anchor 130 located below the main longitudinal beam 110. The first anchor 120 and the second anchor 130 are connected by a first bolt 140 arranged in the vertical direction.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the main longitudinal beam 110 is provided with a vertically penetrating mounting groove 111, which extends along the length of the main longitudinal beam 110 and forms an opening 1111 at its tail end. A first bolt 140 is embedded in the mounting groove 111, and is secured to the top of the first anchor 120 and the bottom of the second anchor 130 by nuts. During assembly and disassembly, it is not necessary to insert the bolt from above; it can be slid directly into the mounting groove 111 through the opening 1111. Conversely, during removal, the first bolt 140 can be slid horizontally out of the opening 1111, greatly simplifying the assembly and disassembly process.

[0026] Furthermore, the main longitudinal beam 110 has a pair of sidewall plates 112 arranged opposite to each other and extending along its length. Each pair of sidewall plates 112 has a plurality of first fixing hole pairs symmetrically arranged. Each first fixing hole pair consists of two first fixing holes 1121 spaced apart in the height direction. The plurality of first fixing hole pairs are spaced apart along the length direction of the sidewall plates 112. When the first bolt 140 slides to a predetermined position, its position can be locked by a small bolt passing through the first fixing hole 1121. Moreover, the arrangement of the plurality of first fixing hole pairs allows for selection of appropriate hole positions to adjust the position of the first bolt 140 according to actual needs.

[0027] Furthermore, such as Figure 1 and Figure 2As shown, the distance between the two pairs of first fixing holes is approximately equal to the diameter of the first bolt 140. When the first bolt 140 slides between the two pairs of first fixing holes, the horizontal sliding of the first bolt 140 can be limited by a small bolt passing through the first fixing hole 1121, thus achieving a better locking effect.

[0028] A pair of reinforcing plates 113 are provided within the mounting groove 111. The reinforcing plates 113 are positioned along the height direction of the main longitudinal beam 110, and each reinforcing plate 113 has a mating hole corresponding to the first fixing hole 1121. The gap between the pair of reinforcing plates 113 is approximately equal to the diameter of the first bolt 140. The reinforcing plates 113 increase the overall strength of the main longitudinal beam 110, especially its ability to withstand vertical stress, thus achieving a more stable anchoring effect. They also limit the movement of the first bolt 140, preventing it from sliding along the width direction of the main longitudinal beam 110.

[0029] Furthermore, such as Figure 1 As shown, there are two first bolts 140, spaced apart along the length of the main longitudinal beam 110, and their tops are connected to the same first anchor 120. A jack 160 is installed on the top of the main longitudinal beam 110, positioned between the pair of first bolts 140. Using two first anchors 120 improves the stability of the anchorage. The jack 160 can apply force between the first anchors 120 and the main longitudinal beam 110, causing the main longitudinal beam 110 to experience a downward thrust, thus achieving a better anchorage effect.

[0030] A support platform 114 is provided on the top of the main longitudinal beam 110, extending laterally from the top of the main longitudinal beam 110. Since the jack 160 is located between the two first bolts 140, it would obstruct the installation and removal of the innermost first bolt 140. By providing the support platform 114, the jack 160 can be pushed laterally when installation or removal is required, thus avoiding obstruction to the sliding of the first bolt 140.

[0031] Furthermore, a second anchor 130 is provided at the bottom of each first bolt 140, and the second anchor 130 is arranged along the width direction of the main longitudinal beam 110. For example... Figure 1 and Figure 3As shown, the second anchor 130 includes a pair of opposing flat plates 131. The pair of flat plates 131 are divided into a relatively independent central through groove 133 and two end through grooves 134 by two vertically arranged connecting plates 132. A first bolt 140 passes through the central through groove 133 and is fixed at the bottom with a nut. Second bolts 150 are provided at both ends of the second anchor 130. The second bolts 150 pass through the end through grooves 134 and connect to the main beam below. The tops of the second bolts 150 are fixed with nuts. The two second anchors 130 can better distribute the force and increase the overall anchoring stability. Placing the first bolt 140 in the middle and the second bolts 150 at both ends can better achieve force balance and prevent the main longitudinal beam 110 from overturning.

[0032] Optionally, the end through groove 134 forms a slot 1341 on the end face of the second anchor 130. The slot 1341 is designed to allow the second bolt 150 to slide directly out of the slot 1341, improving the convenience of disassembly and assembly. It also allows for adjustment of the position of the second bolt 150 within the end through groove 134 by sliding. It is worth noting that, to facilitate the removal of the second bolt 150, the positions of the two connecting plates 132 need to be rationally designed. Before the second bolt 150 at one end abuts against the connecting plate 132 on the same side, the second bolt 150 at the other end has already slid out of the slot 1341, thus ensuring smooth disassembly and assembly.

[0033] Similarly, a plurality of second fixing holes 1311 are symmetrically provided on a pair of plates 131, and the plurality of second fixing holes 1311 are spaced apart along the length direction of the plates 131. The position of the first bolt 140 or the second bolt 150 can be fixed by a small bolt passing through the second fixing hole 1311 to prevent it from slipping.

[0034] In summary, this utility model embodiment provides a layered rear anchor structure 100, which includes a first anchor 120 located above the main longitudinal beam 110 and a second anchor 130 located below the main longitudinal beam 110; the first anchor 120 and the second anchor 130 are connected by a first bolt 140; the main longitudinal beam 110 is provided with a vertically penetrating mounting groove 111, which extends along the length of the main longitudinal beam 110 and passes through the tail end of the main longitudinal beam 110 to form an opening 1111; the first bolt 140 is embedded in the mounting groove 111; the main longitudinal beam 110 has a pair of oppositely arranged side wall plates 112 extending along its length, and a plurality of first fixing holes are symmetrically arranged on the pair of side wall plates 112. During assembly and disassembly, it is not necessary to insert from above; the bolt can be slid directly into the mounting groove 111 from the opening 1111. After sliding to the predetermined position, the position is locked by a small bolt passing through the first fixing hole 1121. Furthermore, the multiple pairs of first fixing holes allow for selection of appropriate hole positions to adjust the position of the first bolt 140 according to actual needs. This layered rear anchor structure 100 significantly improves installation convenience, increases installation efficiency, and saves labor costs.
