Description

Technical Field

[0001] This utility model relates to a casting support mechanism, specifically a casting support mechanism for tunnel construction, belonging to the field of tunnel construction support technology. Background Technology

[0002] During tunnel construction, the tunnel needs to be supported by concrete pouring. Generally, steel arch frames are used for support, and then concrete pouring is carried out for support. The steel arch frame is an important support structure in tunnel engineering. It is mainly composed of steel arch frames, connection systems and auxiliary components. Its core function is to maintain the stability of the surrounding rock after tunnel excavation through a three-dimensional support system. Then, shotcrete, anchor bolts and crossbars are used to form a combined support system to ensure the safety of tunnel construction.

[0003] However, when using steel arch frames for support, due to their large size, they need to be disassembled into sections and transported to the tunnel in batches for on-site assembly. During assembly, multiple curved I-beams are bolted together. Because these curved I-beams are large and heavy, if the bolt joints of two curved I-beams are not aligned, lifting equipment is needed to lift them up, followed by manual alignment before assembly. If deviations occur between the curved I-beams, a second alignment is required, impacting assembly efficiency. Furthermore, when erecting the assembled steel arch, after lifting, the bottom of the arch must be aligned with the pre-measured and positioned location before installation. Lowering the arch, due to its size and weight, easily leads to deviations from the measured and positioned location, necessitating further measurement and positioning, thus affecting installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a casting support mechanism for tunnel construction in order to solve the above-mentioned problems. When assembling the steel arch frame, it is convenient to connect multiple components together, which avoids the time spent aligning multiple components when using bolts for fixing. Then, external equipment is used to lift the assembled steel arch frame. Therefore, when installing the steel arch frame, it can save the time of adjusting the angle of the steel arch frame, which not only improves the installation efficiency of the steel arch frame, but also prevents the steel arch frame from tilting during installation and affecting the installation.

[0027] As a technical optimization of this utility model, the first insertion rod 507 has an overall arc-shaped structure, and the first slot 506 has an overall arc-shaped structure, thereby guiding and limiting the first support member 3 and the column 2.

[0028] As a technical optimization of this utility model, the second insertion rod 509 has an overall arc-shaped structure, and the second slot 508 has an overall arc-shaped structure, thereby guiding and limiting the first support member 3 and the second support member 4.

[0029] As a technical optimization of this utility model, the fixing structure 6 includes a fixing groove 601. The first support member 3 and the second support member 4 are both provided with fixing grooves 601. A positioning plate 602 is fixedly connected inside the fixing groove 601, so as to support the crossbeam.

[0030] As a technical optimization of this utility model, a fixing plate 603 is slidably connected in the fixing groove 601, and a fixing bolt 604 is threadedly connected on the fixing plate 603. The fixing bolt 604 and the corresponding first support member 3 and second support member 4 are slidably connected, thereby enabling the beam to be clamped and fixed.

[0031] As a technical optimization of this utility model, a guide plate 605 is fixedly connected inside the fixing groove 601, and guide grooves 606 are provided on both sides of the fixing plate 603. The guide plate 605 and the guide grooves 606 are slidably connected, thereby limiting the fixing plate 603.

[0034] In use, when the steel arch frame needs to be supported during installation, the base 1 is installed in a fixed position using anchor rods, while the column 2 is laid down. The first support member 3 is then placed on top of the column 2 using the first insert rod 507 and the first slot 506, and bolts are used to fix the first support member 3 and the column 2 together. The second support member 4 is then placed on top of the first support member 3 using the second insert rod 509 and the second slot 508, and bolts are used to fix the first support member 3 and the second support member 4 together. Therefore, when assembling the steel arch frame, it is convenient to connect multiple components together, preventing the time-consuming process of aligning multiple components when using bolts for fixing. Then, external equipment is used to lift the assembled steel arch frame, allowing it to rotate on the base 1 via the pivot 502 and the rotating seat 501. After the steel arch frame rotates until the fixed seat 503 and the fixed ring 504 engage, the fixing rod 505 is inserted into the fixed seat 503 and the fixed ring 504, and then... The positioning ring 703 is inserted into the fixed rod 505 via the slider 704 and the groove 702. When the slider 704 slides into the limiting groove 701, the positioning ring 703 is rotated, thereby limiting and fixing the fixed rod 505. The positioning rod 706 is inserted into the positioning groove 705, which also limits the fixed rod 505. Therefore, when installing the steel arch frame, the angle adjustment time of the steel arch frame can be saved, which not only improves the installation efficiency of the steel arch frame, but also prevents the steel arch frame from tilting during installation, thus avoiding affecting the installation. After the steel arch frame is installed, the two sides of the crossbeam are placed in the positioning plates 602 inside the first support member 3 and the second support member 4, respectively. After placement, the fixing bolts 604 are rotated. Since the fixing plate 603 is positioned by the guide plate 605 and the guide groove 606, the positioning plate 602 and the fixing plate 603 can be tightened when the fixing bolts 604 are rotated, thereby fixing the crossbeam. Therefore, the crossbeam can be supported when it is installed, thus enabling better installation of the steel arch frame.
