Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated pipe structure technology, specifically a prefabricated pipe structure for island and reef engineering. Background Technology
[0002] Developing marine resources is extremely important for socio-economic development, and the development of deep-sea marine resources largely depends on island and reef infrastructure.
[0003] Prefabricated pipe structures for island and reef engineering are a building structure technology specifically designed for island and reef environments. Existing cast-in-place concrete structures cannot use seawater, sea sand, or other island and reef resources to mix concrete due to the corrosion of reinforcing steel. As a result, the long-distance transportation of large quantities of raw materials leads to high construction costs, and the cast-in-place construction method results in a relatively long construction period, which significantly increases construction costs. Therefore, we propose prefabricated pipe structures for island and reef engineering. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated pipe structure for island and reef engineering, which has advantages such as shortening the construction cycle and reducing construction costs. It solves the problems of cast-in-place concrete structures, where the corrosion of steel bars prevents the use of seawater, sea sand, and other island and reef resources to mix concrete, resulting in high construction costs due to the long-distance transportation of large quantities of raw materials, and the relatively long construction period caused by cast-in-place construction, which significantly increases construction costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated pipe structure for island and reef engineering, comprising two aluminum alloy plates, with U-shaped aluminum alloy fixing plates fixed to the left and right sides of the upper and lower aluminum alloy plates by bolts, and limiting grooves opened on the left and right sides of the upper and lower aluminum alloy plates, with limiting blocks slidably inserted into the interior of the limiting grooves on the left and right sides, and the opposite sides of the limiting blocks on the left and right sides being welded and fixed to the opposite side of the U-shaped aluminum alloy fixing plates on the left and right sides, and a connecting mechanism provided on the opposite side of the upper and lower aluminum alloy plates;

The opposite side of the second cement-based precast slabs on the left and right sides is in contact with the left and right sides of the first cement-based precast slabs on the upper and lower sides. Threaded cylinders are welded and fixed to the opposite side of the U-shaped aluminum alloy fixing plates on the left and right sides.
[0007] The connecting mechanism also includes mounting holes that pass through the opposite sides of the left and right second cement-based precast slabs. Fixing bolts are slidably inserted into the mounting holes on both sides, and the opposite sides of the fixing bolts on both sides are threaded into the inside of the threaded cylinders on the left and right sides.
[0008] Furthermore, the gap between the fixing bolt and the mounting hole is matched.
[0009] Furthermore, the gap between the limiting block and the limiting groove is matched, and the left and right sides of the upper and lower aluminum alloy plates are both attached to the opposite side of the left and right U-shaped aluminum alloy fixing plates.
[0010] Furthermore, the connecting rod is located on the longitudinal central axis of the aluminum alloy plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] The prefabricated pipe structure for this island and reef project involves sliding the left and right limiting blocks into the left and right limiting grooves, forming a frame between the upper and lower aluminum alloy plates and the left and right U-shaped aluminum alloy fixing plates. The upper and lower aluminum alloy plates are then fixedly connected to the left and right U-shaped aluminum alloy fixing plates using bolts. Next, the first cement-based precast slabs on the upper and lower sides are placed on the opposite side of the upper and lower mounting plates. Then, the left and right insertion blocks are slidably inserted into the left and right insertion grooves, ensuring that the opposite sides of the second cement-based precast slabs on the left and right sides are in contact with the left and right sides of the first cement-based precast slabs on the upper and lower sides. Finally, the two fixing blocks are... The opposite ends of the fixing bolts are slidably inserted into the mounting holes on the left and right sides, so that the opposite sides of the fixing bolts on the left and right sides are threaded into the inside of the threaded cylinders on the left and right sides, thereby fixing the second cement-based precast slabs on the left and right sides. Then, the first cement-based precast slabs on the upper and lower sides are fixed to the opposite sides of the upper and lower mounting plates by bolts. After that, cement-based grout is poured on the outside of the two aluminum alloy plates and the two U-shaped aluminum alloy fixing plates, and located on the opposite side of the two first cement-based precast slabs and the two second cement-based precast slabs, and densely poured.

[0022] Please see Figures 2 to 3To shorten the construction period and reduce construction costs, in this embodiment, the connecting mechanism 5 includes a connecting rod 501 welded and fixed to the opposite side of the upper and lower aluminum alloy plates 1. An mounting plate 502 is welded and fixed to the opposite side of the upper and lower connecting rods 501. A first cement-based precast plate 503 is bolted to the opposite side of the upper and lower mounting plates 502. Insertion slots 504 are provided on both the left and right sides of the first cement-based precast plates 503. Insertion blocks 505 are slidably inserted into the four insertion slots 504.

[0023] In this embodiment, the left and right limiting blocks 4 can be slidably inserted into the left and right limiting grooves 3 to form a frame with the upper and lower aluminum alloy plates 1 and the left and right U-shaped aluminum alloy fixing plates 2. Then, the upper and lower aluminum alloy plates 1 and the left and right U-shaped aluminum alloy fixing plates 2 are fixedly connected by bolts. Then, the upper and lower first cement-based precast plates 503 are placed on the opposite side of the upper and lower mounting plates 502.

Finally, the opposite ends of the two fixing bolts 509 are slidably inserted.

Then, fix the first cement-based precast slabs 503 on the upper and lower sides to the opposite sides of the mounting plates 502 with bolts.
