Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a bridge construction support device. Background Technology

[0002] During bridge construction, the support of foundation pits, slopes, or temporary structures is a crucial aspect of ensuring construction safety. Traditional support structures often employ steel sheet piles, concrete retaining walls, or steel scaffolds, which, while possessing some supporting capacity, still have many shortcomings in practical application.

[0003] For example, traditional support structures have strong connections and lack buffering and deformation adaptability. When geological conditions are complex or the soil shifts, stress concentration can easily lead to structural deformation or even failure. In addition, the installation and adjustment of existing support devices are often not flexible enough and cannot adapt to changes in the width of different foundation pits or slope angles, affecting construction efficiency and support effect.

[0004] Furthermore, traditional support structures rely on relatively simple anchoring methods, and the connection strength and stability between anchor bolts and support plates still have room for improvement, especially in soft soil or loose strata, where insufficient anchoring force is prone to occur. Therefore, there is an urgent need for a bridge construction support device with a reasonable structure, convenient installation, good deformation adaptability, and stable anchoring capability to improve construction safety and the reliability of the support system.

The mounting grooves and mounting blocks are slidably connected to each other. Elastic deformation fins are fixedly connected to the inner wall of the mounting grooves. The elastic deformation fins cooperate with the mounting blocks. The mounting steel frame is provided with positioning holes, and fixing pins are installed in the positioning holes. The mounting steel frame cooperates with the first support steel plate to push and fix the first support steel plate.

[0009] As a further embodiment of this utility model, a pad is provided between the mounting steel frame and the second support steel plate.

[0010] As a further embodiment of this utility model, a cone head is provided at the bottom of the pad.

[0011] The first and second support steel plates are provided with mounting holes, which are set at an angle. An anchor rods are slidably connected in the mounting holes, and an anchor head is fixedly connected to one end of the anchor rod.

[0012] As a further improvement of this utility model: the other end of the anchor rod is fixedly connected to a screw rod, and a nut is threaded onto the screw rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: The bridge construction support device disclosed in this utility model, by setting first and second support steel plates with mounting blocks and mounting grooves, and in conjunction with internal elastic deformation fins, achieves flexible adjustment of the support width and effective buffering of impact loads.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, see [reference] Figures 1-6 A bridge construction support device includes a first support steel plate 1, a second support steel plate 2, and an installation steel frame 7;

[0023] The first support steel plate 1 is fixedly connected to two sides with mounting blocks 3, and the second support steel plate 2 is fixedly connected to two sides with mounting grooves 4. The mounting grooves 4 and the mounting blocks 3 are slidably connected to each other. The inner wall of the mounting grooves 4 is fixedly connected with elastic deformation fins 5. The elastic deformation fins 5 cooperate with the mounting blocks 3. The mounting steel frame 7 is provided with positioning holes 8. The positioning holes 8 are installed with fixing pins 9. The mounting steel frame 7 cooperates with the first support steel plate 1 to push and fix the first support steel plate 1.

[0024] This invention first places the installation steel frame 7 at the bottom of the edge of the foundation pit, and inserts the fixing pins 9 through the positioning holes 8 into the ground of the foundation pit, thereby fixing the installation steel frame 7 to the bottom of the foundation pit. Then, the first support steel plate 1 and the second support steel plate 2 are inserted between the installation steel frame 7 and the inner wall of the foundation pit, and the installation block 3 is inserted into the installation groove 4, thereby completing the stable connection and fixation of the first support steel plate 1 and the second support steel plate 2, thus completing the support and fixation of the foundation pit. At the same time, when the soil layer of the inner wall of the foundation pit collapses, this invention can... The thrust generated is absorbed through the cooperation of the first support steel plate 1, the second support steel plate 2, and the mounting steel frame 7. During this process, the elastic deformation fins 5 form an elastic gap between the first support steel plate 1 and the second support steel plate 2, thereby preventing deformation of the first support steel plate 1 and the second support steel plate 2 and improving the structural strength of the first support steel plate 1 and the second support steel plate 2. At the same time, this utility model also improves the structural strength of the equipment through the corrugated structure formed by the first support steel plate 1 and the second support steel plate 2.

[0025] In one instance of this embodiment, please refer to Figures 1-6 A pad 14 is provided between the mounting steel frame 7 and the second support steel plate 2. The bottom of the pad 14 is provided with a cone head 15. The present invention fills the gap between the second support steel plate 2 and the mounting steel frame 7 by providing the pad 14, thereby improving the structural stability of the second support steel plate 2. At the same time, the cone head 15 makes it easy to embed the pad 14 between the mounting steel frame 7 and the second support steel plate 2.

[0026] In one instance of this embodiment, please refer to Figures 1-6 The first support steel plate 1 and the second support steel plate 2 are provided with mounting holes 6, which are set at an angle. An anchor rod 10 is slidably connected in the mounting hole 6. An anchor head 11 is fixedly connected to one end of the anchor rod 10, and a screw rod 12 is fixedly connected to the other end of the anchor rod 10. A nut 13 is threaded on the screw rod 12.

[0027] After the first support steel plate 1 and the second support steel plate 2 are installed, the anchor rod 10 can be inserted obliquely into the soil layer inside the outer wall of the first support steel plate 1 and the second support steel plate 2 along the installation hole 6. Thus, the anchor rod 10 and the soil layer are stably connected through the anchor head 11. Then, the nut 13 can be tightened to achieve a stable connection and fixation between the anchor rod 10 and the first support steel plate 1 and the second support steel plate 2 through the threaded connection between the screw rod 12 and the nut 13, thereby improving the stability of the connection between the first support steel plate 1, the second support steel plate 2 and the soil layer.
