Detailed Description
Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.
Example 1:
(1) drilling holes in U-shaped pultruded profiles
A glass Fiber Reinforced Plastic (FRP) U-shaped section 1 (the minimum width of the U-shaped section 1 is 300mm) is manufactured by adopting a pultrusion process, 2 rows of holes with the same diameter are drilled on the upper and lower sides of two flanges of the section 1 respectively, and the distance between the axis of each hole and the outer side surface of a web (the outer lower surface of the U-shaped section 1) is 20-30 mm. The upper row of holes are uniformly distributed along the longitudinal direction (the direction vertical to the cross section) of the flange of the U-shaped section, and the hole distance is 150-300 mm. The distance between the axis of the lower row of holes and the flange edge (the top surface of the U-shaped section bar 1) is 15-20 mm.
(2) The FRP ribs are arranged in a downward penetrating way in the hole, and then concrete is poured into the bottom of the inner side of the U-shaped section
The U-shaped material 1 is placed in flat shallow water side by side, two rows of holes are aligned, the FRP rib 6 is firstly penetrated into the lower row of holes, and a rib can be penetrated through every other row of holes. The diameter of the FRP rib 6 is about 8-12mm, the two ends of the two outermost sides of the FRP rib 6 are made into threads with the diameter of 200-300mm, and the FRP nuts 4 are tightened on the two outermost sides of the FRP rib 6. Increasing the number of U-profiles 1 arranged side by side makes it possible to achieve an increase in the dimension perpendicular to the axial direction of the U-profiles 1. When the FRP ribs 6 are not long enough, the FRP nuts can be tightened on the inner side of one of the U-shaped members 1 in the middle, and the FRP ribs 6 in two directions are shared in the U-shaped members 1 to realize the lap joint.
Then, the glass fiber reinforced plastic partition plate 10 is inserted between the FRP ribs 6 on the inner side of the U-shaped material 1. The width of the glass fiber reinforced plastic partition plate 10 is matched with the width of the inner side of the U-shaped section bar 1, the glass fiber reinforced plastic partition plate 10 is inserted into the bottom surface of the U-shaped section bar 1, and the height of the glass fiber reinforced plastic partition plate is flush with the lower discharge port in the U-shaped section bar 1; the glass fiber reinforced plastic partition board 10 is arranged perpendicular to the U-shaped section bar 1; waterproof adhesive is coated at the joint of the glass fiber reinforced plastic partition board 10 and the inner side of the flange of the U-shaped section bar 1; the lower part of the glass fiber reinforced plastic partition plate 10 is provided with a rectangular hole 11 so as to be better bonded with the concrete 3. The bottom of the inner side of the section bar is poured with fine aggregate concrete 3 to fix the FRP ribs 6 and the glass fiber reinforced plastic partition boards 10, and the bottom of the section bar 1 has certain weight, so that the raft is more stable. The thickness of the bottom concrete 3 is less than or equal to 60 mm; the bottom fine aggregate concrete 3 is doped with a proper amount of expanding agent, so that the fine aggregate concrete 3 cured in water generates micro-expansion, the FRP ribs 6 are in a pre-stretched state, and the U-shaped sections 1 are mutually compressed. Water between the partition boards 10 is sucked out, and the U-shaped section bar 1 can float out of the water surface.
(3) Putting the glass fiber reinforced plastic pultrusion section 5 with the square-shaped cross section and two sealed ends into the U-shaped section 1
Pultrusion profiles with a square-back cross-section were made and both ends were sealed in the factory. When sealing, firstly, the periphery of the port of the glass fiber reinforced plastic plate 5 is fully coated with epoxy resin adhesive, then a plate 7 which is just in size to be plugged into the port of the glass fiber reinforced plastic plate 5 is plugged into the glass fiber reinforced plastic plate 5, and the outer side surface of the plate 7 and the port of the glass fiber reinforced plastic plate 5 are on the same plane. 5, the product is put into water after the two ends are sealed, and no bubble is discharged, so that the product is qualified. Then, after the two ends of 5 are dried, epoxy resin adhesive is coated on the outer surface of the sealed end, and 8 is pasted to protect the sealed end. The outer edges of each 5 of the sizes of the glass fiber reinforced plastic plates 8 are equal.
The glass fiber reinforced plastic pultruded profile 5 with a square-shaped cross section and sealed at two ends is placed between each partition board 10 in the U-shaped profile 1, when the end of the U-shaped profile 1 needs to be lengthened, the partition board 10 at the end leaves half the length of the square-shaped profile 5 away from the end (see the end in detail). A plurality of square-back-shaped sectional materials 5 can be placed in one section of the U-shaped sectional material 1. When the end of the U-shaped section bar 1 does not need to be lengthened (namely the edge of the raft), the length of the partition board 10 from the end needs to be 30-60mm, and 1 clip-shaped section bar 5 needs to be placed on the inner side of the partition board 10.
(4) Bundled U-shaped section bar 1, grid and floor
Before pouring fine aggregate concrete on the tops of the U-shaped section bars 1 and the square-shaped section bars 5, non-metal cables 16 (such as three-strand or four-strand nylon multifilament cables, polypropylene and polyester mixed ropes and the like) need to penetrate through the upper row of holes, the flanges (vertical walls) of the attached U-shaped section bars 1 need to be connected together by using ropes, and the flanges (vertical walls) of the attached U-shaped section bars 1 are crossed from the upper row of holes on one flange (vertical wall) of the same U-shaped section bar 1 to the top surface of the square-shaped section bar 5 and penetrate into the hole 2-1 on the other flange (vertical wall) of the U-shaped section bar 1 so as to press the square-shaped section bar 5.
And a glass fiber reinforced plastic grid (small spacing grid) 17 is laid on the rope on the inner side of the U-shaped section bar 1 at the top of the square-shaped section bar 5. The height of the glass fiber reinforced plastic grid 17 is equal to the distance from the upper surface of the rope to the top of the side wall of the U-shaped section bar 1 (when the designed height of the space is larger, the top is subjected to waterproof treatment to prevent water from entering the U-shaped section bar 1 from the upper side and the side surface). Then, the glass fiber reinforced plastic grating 17 is paved with an industrial rubber floor 18, and the joint of the industrial rubber floor 18 is connected and waterproofed by a waterproof adhesive.
(5) When the end of the U-shaped section bar 1 needs to be lengthened, the two U-shaped section bars 1 are butted
The U-profile 1 has a limited length and when a raft of a larger length is required the joints of the U-profile 1 have to be designed. First, the U-profiles 1 in the raft sheets should overlap by stagger.
Before the concrete 3 is poured at the joint 12 of the U-shaped section bar 1, the fabric net 9 is prepared, each fabric 9 extends into the two sides of the joint 12 by about 300-500mm, namely the length of the fabric 9 is 600-1000mm, the width is equal to the width of the inner side of each U-shaped section bar 1, 3-5 layers of the fabric net 9 are paved in the concrete 3 at the joint 12 (when the space at the lower part of the FRP rib 6 is insufficient, about 2 layers of the fabric net 9 can be paved at the upper part of the FRP rib 6), and the fabric net 9 used at the joint 12 is made of high-strength fibers such as carbon fibers.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
