Description

Technical Field

[0001] This utility model relates to the field of grating plate fixing technology, and specifically discloses a grating plate fixing device. Background Technology

[0002] Fiberglass grating (also known as FRP grating) is a porous mesh-like sheet material made of fiberglass as reinforcement and unsaturated polyester resin as matrix, manufactured through pultrusion or molding processes. It possesses lightweight, corrosion resistance, and insulation properties, and is widely used in chemical platforms, offshore facilities, and wastewater treatment plants. In practical engineering, FRP grating needs to be fixedly installed on a base surface as a load-bearing structure, and its installation reliability directly affects its service life and safety.

[0003] In existing technologies, bolt fixing and adhesive fixing methods are commonly used when installing and fixing fiberglass grating. Bolting requires pre-drilling holes at the edges of the grating, but this can easily lead to breakage of the fiberglass layer, reducing its load-bearing capacity. Adhesive fixing uses epoxy resin to bond to the substrate, but the adhesive has poor weather resistance, is prone to aging and failure after long-term use, and cannot be reused. Therefore, a grating fixing device is needed to solve this problem. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5A grating fixing device includes a base plate 1 and a fiberglass grating 2. The fiberglass grating 2 has several square grids 3. A limiting mechanism is provided on the upper side of the base plate 1. The limiting mechanism includes a vertical plate 4 located at the upper end of the base plate 1. A limiting plate 5 is fixedly connected to the right end of the vertical plate 4. A limiting block 6 extending into and matching one of the square grids 3 is fixedly connected to the lower end of the limiting plate 5.

[0026] A locking mechanism is provided on the left side of the vertical plate 4. The locking mechanism includes a flat plate 8 fixedly connected to the left end of the vertical plate 4. A first positioning hole 9 is opened through the outer wall of the flat plate 8. A second positioning hole 10 is opened at the upper end of the base plate 1. A first bearing steel column 11 adapted to the first positioning hole 9 and the second positioning hole 10 is inserted between them. A first threaded hole 13 is opened on the bottom side of the inner wall of the second positioning hole 10. A first connector 15 is fixedly connected to the lower end of the first bearing steel column 11. A first screw 14 threadedly connected to the inner wall of the first threaded hole 13 is fixedly connected to the lower end of the first connector 15. A first torsion block 12 is fixedly connected to the upper end of the first bearing steel column 11.

[0027] A connecting mechanism is provided on the upper side of the substrate 1.

[0028] In this embodiment: When installing the fiberglass grating 2, it is first placed in a preset position on the upper side of the substrate 1, and the limiting block 6 is inserted into the selected square grid 3 in the leftmost column of the fiberglass grating 2. Since the limiting block 6 and the square grid 3 are size-matched, the fiberglass grating 2 is prevented from moving horizontally by the lateral engagement, thereby completing the initial positioning.

[0029] After initial positioning, the first bearing steel column 11 is further fixed by locking mechanism. The first positioning hole 9 of the plate 8 and the second positioning hole 10 of the base plate 1 are inserted in sequence. Then, the first torsion block 12 is rotated with a wrench to drive the first screw 14 to be screwed into the first threaded hole 13, so that the vertical plate 4 is tightly connected to the base plate 1. At this time, the first bearing steel column 11 bears the horizontal load of the vertical plate 4, and the limiting plate 5 is tightly attached to the upper surface of the fiberglass grating 2, thereby preventing the fiberglass grating 2 from vertically displacing.

[0030] The connecting mechanism is used to splice and fix two adjacent fiberglass gratings 2. After the splicing is completed, the installation steps of the limiting mechanism and the connecting mechanism are repeated for the rightmost fiberglass grating 2 to complete the overall fixation. By combining the above methods, it is possible to achieve the purpose of not needing to pre-drill holes on the edge of the fiberglass grating 2 during installation and fixing, thereby preventing the fiberglass layer from breaking and improving the load-bearing capacity.

[0031] Meanwhile, the limiting mechanism, in conjunction with the locking mechanism, restricts and locks the two rows of fiberglass gratings 2 on the left and right sides, and in conjunction with the connecting mechanism, locks each pair of adjacent fiberglass gratings 2, greatly improving the stability during fixing. Moreover, all components of the fixing device, such as the first bearing steel column 11, the second bearing steel column 21, the limiting block 6, the U-shaped plate 16, etc., are installed by threaded connection or plug-in connection, so that each component can be easily removed, realizing the reusability of the fiberglass gratings 2.

[0032] As a technical optimization of this utility model, the connecting mechanism includes a U-shaped plate 16 located at the upper end of the substrate 1 and attached to the inner wall of one of the square grids 3. Mounting plates 17 are fixedly connected to both ends of the U-shaped plate 16. The outer walls of the two mounting plates 17 are provided with third positioning holes 18. Two fourth positioning holes 20 are provided at the upper end of the substrate 1. Second bearing steel columns 21 adapted to the third positioning holes 18 and the fourth positioning holes 20 are inserted between them. The bottom ends of the inner walls of the two fourth positioning holes 20 are provided with second threaded holes 22. The lower ends of the two second bearing steel columns 21 are fixedly connected with second connectors 24. The lower ends of the two second connectors 24 are fixedly connected with second screws 23 that are threaded to the inner walls of the second threaded holes 22. The upper ends of the two second bearing steel columns 21 are fixedly connected with second torsion blocks 19.

[0033] In this embodiment: the U-shaped plate 16 is inserted into two selected square grids 3 of the two fiberglass gratings 2. The left and right ends of the inner wall of the U-shaped plate 16 are in contact with the inner walls of the two square grids 3 respectively, and the upper end of the inner wall of the U-shaped plate 16 contacts the upper ends of the two adjacent fiberglass gratings 2. Then, the second supporting steel column 21 is inserted into the third positioning hole 18 on the mounting plate 17 and the fourth positioning hole 20 on the base plate 1. Similarly, the second connector 24 has a conical structure, which makes it easy for the second screw 23 to be aligned with the second threaded hole 22 at the bottom of the inner wall of the fourth positioning hole 20. The Allen wrench is inserted into the regular hexagonal groove at the upper end of the second torsion block 19, and the second torsion block 19 is rotated to screw the second screw 23 into the second threaded hole 22, so as to firmly connect the U-shaped plate 16, thereby allowing adjacent fiberglass gratings 2 to be spliced.

[0034] As a technical optimization of this utility model, a tapered guide head 7 is fixedly connected to the lower end of the limiting block 6.

[0035] In this embodiment: during the process of inserting the limiting block 6 into the square grid 3, the tapered guide head 7 at the lower end of the limiting block 6 plays a guiding role, so that the limiting block 6 can enter the square grid 3 more smoothly.

[0036] As a technical optimization of this utility model, the outer wall of the first twisting block 12 is a regular hexagonal structure, and the upper ends of the two second twisting blocks 19 are all provided with regular hexagonal grooves.

[0037] In this embodiment: the regular hexagonal outer wall structure of the first toggle block 12 makes it easy to rotate it with a wrench to tighten the first screw 14; the regular hexagonal groove at the upper end of the second toggle block 19 makes it easy to insert and rotate an internal hex wrench to tighten the second screw 23.

[0038] As a technical optimization of this utility model, the first connector 15 and the two second connectors 24 are both conical structures.

[0039] In this embodiment, the conical structure of the first connector 15 and the second connector 24 serves as an automatic guide when the first screw 14 and the second screw 23 are aligned with the first threaded hole 13 and the second threaded hole 22, enabling the screws to be screwed into the threaded holes more accurately.

[0040] As a technical optimization of this utility model, a reinforcing rib is welded between the lower end of the vertical plate 4 and the right end limiting plate 5.

[0041] In this embodiment, the reinforcing rib between the vertical plate 4 and the limiting plate 5 enhances the connection strength between the vertical plate 4 and the limiting plate 5, enabling them to work together when subjected to external forces and reducing deformation.

[0042] As a technical optimization of this utility model, the first load-bearing steel column 11 and the two second load-bearing steel columns 21 are both made of alloy steel.

[0043] In this embodiment, the first load-bearing steel column 11 and the second load-bearing steel column 21 are made of alloy steel. Alloy steel has high strength and good toughness, and can withstand large loads, ensuring that it will not deform or be damaged during the fixing process.

[0044] The working principle and usage process of this utility model are as follows: When installing the fiberglass grating 2, it is first placed in the preset position on the upper side of the base plate 1. The tapered guide head 7 at the lower end of the limiting block 6 can guide the limiting block 6 to be accurately inserted into the selected square grid 3 in the leftmost column of the fiberglass grating 2. Since the size of the limiting block 6 and the square grid 3 are matched, the fiberglass grating 2 is prevented from moving horizontally by the horizontal engagement, thereby completing the initial positioning.

[0045] After initial positioning, the first bearing steel column 11 is further fixed by the locking mechanism. The first positioning hole 9 of the plate 8 and the second positioning hole 10 of the base plate 1 are inserted in sequence. The conical first connector 15 at its lower end can make the first screw 14 automatically align with the first threaded hole 13. The first torsion block 12 on the hexagonal outer wall is rotated with a wrench to drive the first screw 14 into the first threaded hole 13, so that the vertical plate 4 is tightly connected to the base plate 1. At this time, the first bearing steel column 11 bears the horizontal load of the vertical plate 4, and the limiting plate 5 is tightly attached to the upper surface of the fiberglass grating 2, thereby preventing the fiberglass grating 2 from vertically displacing.

[0046] The connecting mechanism is used to splice two adjacent fiberglass gratings 2. The U-shaped plate 16 is inserted into two selected square grids 3 of the two fiberglass gratings 2. The left and right ends of the inner wall of the U-shaped plate 16 will be in contact with the inner walls of the two square grids 3 respectively, and the upper end of the inner wall of the U-shaped plate 16 will contact the upper end of the two adjacent fiberglass gratings 2. Then, the second bearing steel column 21 is inserted into the third positioning hole 18 on the mounting plate 17 and the fourth positioning hole 20 on the base plate 1. Similarly, the second connector 24 has a conical structure, which makes it easy for the second screw 23 to be aligned with the second threaded hole 22 at the bottom of the inner wall of the fourth positioning hole 20. The Allen wrench is inserted into the regular hexagonal groove at the upper end of the second torsion block 19. The second torsion block 19 is rotated so that the second screw 23 is screwed into the second threaded hole 22, and the U-shaped plate 16 is firmly connected, so that adjacent fiberglass gratings 2 can be spliced.

[0047] For the rightmost fiberglass grating 2, repeat the installation steps of the above-mentioned limiting mechanism and connecting mechanism to complete the overall fixation. By combining the above methods, it is possible to achieve the purpose of not needing to pre-drill holes at the edge of the fiberglass grating 2 during installation and fixation, thereby preventing the fiberglass layer from breaking and improving the load-bearing capacity.

[0048] Meanwhile, the limiting mechanism, in conjunction with the locking mechanism, restricts and locks the two rows of fiberglass gratings 2 on the left and right sides, and in conjunction with the connecting mechanism, locks each pair of adjacent fiberglass gratings 2, greatly improving the stability during fixing. Moreover, all components of the fixing device, such as the first bearing steel column 11, the second bearing steel column 21, the limiting block 6, the U-shaped plate 16, etc., are installed by threaded connection or plug-in connection, so that each component can be easily removed, realizing the reusability of the fiberglass gratings 2.
