[0002] When large protective netting equipment is installed on the construction site, such as Figure 1 As shown, angle steel of a certain size is generally used as the clamping device for the protective net. The top edge of the protective net is fixedly connected to the angle steel by fastening bolts. Screws (adjusting bolts) are installed on the angle steel. The tensioning function of the protective net is achieved by tightening the screws and nuts.

[0003] The main problems with this type of device are: 1. The verticality of the protective net is greatly affected by the size of the holes in the main structure, and the adjusting bolts are prone to misalignment with the holes in the structure; 2. The verticality of the protective net cannot be adjusted; 3. It cannot be adjusted in the X and Y directions, and the tension and flatness control of the protective net are limited. Summary of the Invention

[0004] The purpose of this invention is to provide a fastening and tensioning device that can achieve simple adjustment in the X, Y, and Z axes. Several different fastening and tensioning devices can be manufactured, and the device can be easily adjusted by sliding T-bolts in the H-channel steel according to the site environment or deviation of the structure.

[0028] To achieve the above objectives, the present invention addresses the following technical problem:

[0029] Combination Figures 2-4As shown, this embodiment provides a protective net tensioning device for fixing and tensioning a protective net 600, comprising: an upper adjusting tensioning device 10 for adjusting the position of the protective net 600 along a first direction; a lower adjusting tensioning device 20 for adjusting the position of the protective net 600 along a second direction; and a protective net clamp 40 for clamping the protective net 600, wherein the lower adjusting tensioning device 20 is connected to the protective net clamp 40; the first direction and the second direction are perpendicular to each other, the first direction is located in a direction perpendicular to the plane of the protective net 600, and the second direction is a direction parallel to the extension direction of the protective net 600.

[0030] like Figure 4 As shown, the first direction is the X-axis direction, and the second direction is the Y-axis direction.

[0031] In this embodiment, the upper tensioning device 10 includes two first halfen channel steels 100, both galvanized. The two first halfen channel steels 100 are installed parallel to each other along the X-axis on the structural body (…). Figures 2-3 The structural body surface (not shown in the image) is a surface that is not part of the structure. Figure 4 As shown, it is connected to the structural body surface by welding.

[0032] Two first adjusting bolt groups, each first adjusting bolt group comprising: two first T-bolts 101 and two pairs of hexagonal nuts (102, 103) and flat washers that match the first T-bolts 101 (i.e., each first T-bolt 101 is equipped with two pairs of hexagonal nuts and flat washers). The first T-bolts 101 have a strength grade of 8.8 and are hot-dip galvanized. Two first T-bolts 101 are installed within the first H-channel steel 100; the first T-bolts 101 are free to move along the X-axis within each first H-channel steel 100. One pair of hexagonal nuts and flat washers is used to tighten the first T-bolts 101 after their positions have been adjusted. The other pair of hexagonal nuts and flat washers is used to mount the upper adjusting tensioning device 10 onto the fixing plate 200 of the lower adjusting tensioning device 20.

[0033] The lower tensioning adjustment device 20 includes a fixing plate 200 (in this embodiment, the fixing plate 200 is a rectangular steel plate, but the invention is not limited thereto), the fixing plate 200 is 12mm thick, and the material is Q235B. The surface of the fixing plate 200 has four T-bolt connection holes drilled for connection with the four first T-bolts 101 of the upper tensioning adjustment device 10. That is, the first T-bolts 101 pass through the T-bolt connection holes and are tightened and fixed using hexagonal nuts and flat washers. The lower tensioning adjustment device 20 is located between the T-bolt connection holes.

[0034] The upper tensioning device 10 is located above the fixed plate 200.

[0035] Two second H-channel steels 300 are fixed to the bottom surface of the fixed plate 200; that is, two parallel second H-channel steels 300 are installed on the bottom surface of the fixed plate 200 along the Y-axis direction and connected to the fixed plate 200 by welding.

[0036] Two second adjusting bolt groups, one end of each second adjusting bolt group is correspondingly set inside the second halfen channel steel 300; the other end is connected to the protective net clamp 40.

[0037] Each of the second adjusting bolt groups includes: two second T-bolts 301, two pairs of hexagonal nuts (302, 303) that match the second T-bolts 301, and flat washers.

[0038] In this embodiment, two second T-bolts 301 are installed inside each second H-channel steel 300, for a total of four. The strength grade of the second T-bolts 301 is 8.8, and the surface treatment is hot-dip galvanized. The second T-bolts 301 can move freely along the Y-axis within each second H-channel steel 300. Each second T-bolt 301 is equipped with two pairs of hexagonal nuts (302, 303) and flat washers. One pair of hexagonal nuts (302) and flat washers is used to tighten the second T-bolts 301 after adjusting their position, and the other pair of hexagonal nuts (303) and flat washers is used to connect with the angle steel 400 of the lower protective net clamp 40.

[0039] That is, the extension directions of the first Huffen channel steel 100 and the second Huffen channel steel 300 are perpendicular to each other.

[0040] The protective net clamp 40 includes: a pair of angle steels 400, each measuring 100*63*10 mm and made of Q235B material, with a length determined by the dimensions of the protective net 600; and several fastening bolts 500. Each pair of angle steels 400 has a fastening bolt connection hole on one of its two right-angled sides. The protective net 600 is clamped between the pair of angle steels 400, with the fastening bolts 500 passing through the fastening bolt connection holes and the protective net 600 to secure it between the two angle steels 400.

[0041] Bolt holes 401 are provided on the other two right-angled sides respectively. The adjusting bolt of the lower adjusting tensioning device 20 passes through the bolt holes 401 to fix the lower adjusting tensioning device 20 on the angle steel 400.

[0042] In this embodiment, the two right-angled sides of the pair of angle steel are each drilled with a fastening bolt hole. One right-angle bolt hole is used to connect with the lower tension adjustment device, and the other right-angle bolt hole is used to clamp the protective net. The fastening bolts are hexagonal bolts with hot-dip galvanized surface treatment, strength grade 8.8, and are equipped with a pair of hexagonal nuts and flat washers.

[0043] On the other hand, the present invention also provides a method for installing a protective net using the protective net tensioning device as described above, wherein a protective net clamp 40 is used to clamp the protective net 600; multiple sets of the protective net tensioning devices are spaced apart on the protective net clamp 40; and the protective net 600 is installed on the object to be installed by adjusting the tensioning device 10 at the upper part of each set of the protective net tensioning devices.

[0044] The protective net 600 is tensioned by adjusting the upper tensioning device 10 and the lower tensioning device 20 in each set of the protective net tensioning devices. The tensioning devices for the protective net 600 consist of several components depending on the size of the protective net 600, with a spacing of 500-700 mm between each device. This embodiment provides a practical protective net tensioning device that adjusts the position of the protective net 600 in the Z-axis direction by adjusting the spacing between two pairs of hexagonal nuts (102, 103) and / or the spacing between hexagonal nuts (302, 303). The position of the protective net 600 in the X-axis direction is adjusted by adjusting the position of the first T-bolt 101 within the first H-channel steel 100. The position of the protective net 600 in the Y-axis direction is adjusted by adjusting the position of the second T-bolt 301 within the second H-channel steel 300. Therefore, the protective net tensioning device of this embodiment can adjust and tension the protective net in the X, Y, and Z axes.

[0045] In summary, this embodiment provides a fastening and tensioning device that can achieve simple adjustment in the X, Y, and Z axes. Several different fastening and tensioning devices can be manufactured, and the T-bolts can be slid in the H-channel steel to achieve simple adjustment according to the site environment or deviation of the structure.

[0046] In this embodiment, the installation requirements can be met by adjusting the positions of the T-bolts of the lower and upper tensioning devices, and then checking the verticality, flatness, and tension of the protective net.

[0047] This embodiment is used for the installation of protective netting, effectively solving the problems of verticality and surface flatness during installation, facilitating on-site installation and adjustment, and ensuring installation quality. At the same time, this tooling also features high detachability, portability, and replaceability.
