Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation reinforcement technology, and in particular to a prefabricated component for a ladder cage foundation. Background Technology
[0002] In existing highway engineering or other construction projects, when constructing components, necessary construction procedures such as component inspection, concrete pouring, protection, curing, and insulation are required. When carrying out the above construction procedures, it is usually necessary to first erect a cage ladder on the outside of the component.
[0003] In typical construction of a ladder cage foundation, a portion of reinforcing steel is placed inside during the pouring process to form a steel frame. Concrete is then poured into the steel frame and the foundation pit to form the ladder cage foundation. The stability of the ladder cage foundation during use determines its quality. If only the steel frame and concrete pouring of the ladder cage foundation are used, the stability of the ladder cage foundation will be insufficient, and its stability during vibration will be poor. Therefore, it is necessary to provide a new type of precast ladder cage foundation component to solve the above-mentioned technical problems. Utility Model Content

[0006] The foundation base has a fixing mechanism installed at the four corners of the bottom of the inner cavity. The bottom of the cement steel plate has a reinforcing rod installed at the middle of the front and rear ends. The outer surface of the reinforcing rod is fitted with a reinforcing mechanism.
[0007] As a further description of the above technical solution: the fixing mechanism includes fixing rods fixedly connected to the four corners of the bottom of the inner cavity of the foundation base, stabilizing plates are installed obliquely on the left and right sides of the fixing rods, and fixing sleeves are fixedly connected to the four corners of the bottom of the cement steel plate.
[0008] As a further description of the above technical solution: the fixing sleeve has a slot that is compatible with the fixing rod and the stabilizing plate.
[0009] As a further description of the above technical solution: the reinforcement mechanism includes a connecting ring sleeved on the reinforcement rod, with fixing bolts inserted at the four corners of the outer surface of the connecting ring, and extension rods fixedly connected to the four bottom corners of the connecting ring, with protruding sections fixedly connected to the bottom of the extension rods.

[0011] As a further description of the above technical solution: the foundation base is provided with slots that are compatible with the reinforcing rods and extension rods.
[0012] This utility model provides a precast component for a ladder cage foundation. It has the following beneficial effects:
[0013] By setting a fixing mechanism, with stabilizing plates located on both sides of the fixing rod, the stabilizing plates are used to improve the stability of the fixing rod on the cement steel plate and ensure the reliability of the fixing mechanism installation. By setting a fixing sleeve, it is easy to connect the cement steel plate to the fixing rod, which facilitates the improvement of the stability of the cement steel plate.
[0014] By incorporating reinforcing rods, insertion into the foundation is facilitated, increasing the stability of the foundation base during use. Furthermore, the reinforcing mechanism allows the reinforcing rods to connect with the bottom of the foundation during insertion, increasing the contact area between the rods and the ground, thereby enhancing the stability of the rods during use and reinforcing the foundation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1, Reference Figure 1 and Figure 2 This utility model discloses a prefabricated component for a ladder cage foundation, which can solve the problem that the existing ladder cage foundation has a partial steel reinforcement frame and concrete pouring, which leads to the lack of stability of the ladder cage foundation and low stability effect when vibration occurs. It includes a foundation base 1, a cement steel reinforcement plate 2 installed on the top of the foundation base 1, a fixing plate 3 fixedly connected to the four corners of the upper surface of the cement steel reinforcement plate 2, and a connecting pipe 4 inserted in the middle of the fixing plate 3.
[0024] Fixing mechanism 5 is installed at the four corners of the bottom of the inner cavity of the foundation base 1. Reinforcing rod 6 is installed at the middle of the front and rear ends of the bottom of the cement steel plate 2. Reinforcing mechanism 7 is sleeved on the outer surface of the reinforcing rod 6.
[0025] Working principle: The foundation base 1 and the cement steel plate 2 facilitate the formation of the main body of the ladder cage foundation. The fixing plate 3 and the connecting pipe 4 facilitate the installation and positioning of the ladder cage. The fixing mechanism 5 is located on both sides of the fixing rod 501 through the stabilizing plate 502. The stabilizing plate 502 is used to improve the stability of the fixing rod 501 fixed on the cement steel plate 2. The reinforcing rod 6 and the reinforcing mechanism 7 increase the firmness of the foundation base 1 during use. The reinforcing mechanism 7 can be connected to the bottom of the foundation to increase the contact area between the reinforcing rod 6 and the foundation.
[0026] Example 2, refer to Figure 3 , Figure 4 and Figure 5This embodiment addresses the problem that the existing ladder cage foundation structure, with its partial steel reinforcement and concrete pouring, suffers from insufficient stability and poor stabilization during vibrations. The proposed ladder cage foundation prefabricated component further includes a fixing mechanism 5 comprising fixing rods 501 fixedly connected to the four corners of the bottom of the inner cavity of the foundation base 1. Stabilizing plates 502 are obliquely installed on the left and right sides of the fixing rods 501. Fixing sleeves 503 are fixedly connected to the four corners of the bottom of the cement steel reinforcement plate 2. The fixing sleeves 503 have openings for connection with the fixing rods 501 and... The stabilizing plate 502 has a matching slot, and the reinforcing mechanism 7 includes a connecting ring 701 sleeved on the reinforcing rod 6. The four corners of the outer surface of the connecting ring 701 are fitted with fixing bolts 702. The four corners of the bottom of the connecting ring 701 are fixedly connected with extension rods 703. The bottom of the extension rods 703 is fixedly connected with protruding sections 704. The connecting ring 701 has threaded holes that match the fixing bolts 702. The connecting ring 701 and the fixing bolts 702 form a rotating connection mechanism. The foundation base 1 has slots that match the reinforcing rod 6 and the extension rods 703.
[0027] Working principle: When using this device, after installing the foundation base 1 in a suitable position, the fixing sleeve 503 at the bottom of the cement steel plate 2 is fitted onto the fixing rod 501 and the stabilizing plate 502. The stabilizing plate 502 is located on both sides of the fixing rod 501, and its function is to improve the stability of the fixing rod 501 on the cement steel plate 2, ensuring the reliability of the fixing mechanism 5. Before placing the cement steel plate 2, the connecting ring 701 is fitted onto the reinforcing rod 6. After aligning the extension rod 703 with the slot, the fixing bolt 702 is tightened. The connecting ring 701 is fixed to the reinforcing rod 6, making it easy to insert into the foundation and increasing the stability of the foundation base 1 during use. When the reinforcing rod 6 is inserted into the foundation, it can be connected to the bottom of the foundation through the extension rod 703 to increase the contact area between the reinforcing rod 6 and the foundation, thereby increasing the stability of the reinforcing rod 6 during use and reinforcing the foundation. By providing the protruding section 704, it is easy for the extension rod 703 to be effectively inserted into the bottom of the foundation. Through the above device, the stability of the cage foundation can be effectively increased, and the stability during vibration can be improved.
