Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fixing device for a protective net. Background Art

[0002] During construction, it is often necessary to pile up building materials (such as soil, sand, ash, etc.) on the construction site. If the building materials are exposed to the air, they are easily blown up by the wind to form dust, which not only pollutes the environment but also wastes raw materials. Therefore, it is necessary to cover and fix the surface of the building with a protective net.

[0003] The existing fixing method is to set the protective net between the upper and lower fixing plates, which are connected by rocker threads, and the lower structure is fixed to the ground, and the upper and lower fixing plates squeeze the protective net to fix the protective net. If this method is used to fix the protective net, the compression and fixing structure is exposed and protruding, which can easily trip the staff and pose a safety hazard. When the ground is inclined, the compression and fixing structure cannot fit with the ground, resulting in poor fixing effect. In addition, the length of the existing compression and fixing structure is fixed. If the soil where the building materials are piled is relatively soft, the fitting force between the compression and fixing structure and the ground is relatively small, which makes the compression and fixing structure easy to loosen, reducing the firmness of the fixed protective net.

[0035] Embodiment 1

[0036] This embodiment provides a fixing device for a protective net, such as Figure 1 As shown, the fixing device includes an insert 1, a clamping assembly 2 and an extractor 3. Among them, the lower end of the insert 1 is configured to penetrate the protective net (not shown in the figure) and be inserted and fixed to the ground. The clamping assembly 2 includes at least one pressure rod 21, and the pressure rod 21 is connected to the upper end of the insert 1. When the insert 1 penetrates the protective net and is inserted and fixed to the ground, the pressure rod 21 can press the protective net so that the protective net can be fixed on the ground. Through the coordinated cooperation of the insert 1 and the pressure rod 21, the protective net can be close to the ground, so that the protective net can completely cover the wrapped material to prevent material waste from causing environmental pollution. The extractor 3 includes a connecting sleeve 31 and a handle 32. The connecting sleeve 31 is rotatably sleeved on the pressure rod 21 around the axial direction of the pressure rod 21, and the handle 32 is connected to the connecting sleeve 31.

[0037] When fixing the protective net, the staff can hold the handle 32, pass the lower end of the plug-in 1 through the protective net, and insert the plug-in 1 below the ground until the pressure rod 21 presses the protective net to the ground, and then turn the handle 32 to make the handle 32 as close to the ground as possible. By setting the pressure rod 21, the protective net can be completely pressed to the ground, ensuring the fixing effect of the protective net, preventing external forces such as wind from carrying building materials, causing waste of raw materials and environmental pollution. In addition, after pressing and fixing the protective net, by turning the handle 32, the handle 32 can be pressed against the ground, reducing the protruding height of the fixing device, making the handle 32 as flush with the ground as possible, preventing the staff from tripping and reducing safety hazards.

[0038] In this embodiment, the pressing assembly 2 includes a pressing rod 21 .

[0039] Alternatively, if Figure 1 As shown, the pressure rod 21 inserted into the connecting sleeve 31 includes a first rod segment 211 and a second rod segment 212 connected to each other, and the upper end of the insert 1 is connected to the junction of the first rod segment 211 and the second rod segment 212. The extraction member 3 includes two connecting sleeves 31, and the two connecting sleeves 31 are respectively sleeved on the first rod segment 211 and the second rod segment 212, and the two ends of the handle 32 are respectively connected to the two connecting sleeves 31. It can be seen that the pressure rod 21 and the insert 1 are connected in a T-shape. The T-shaped connection can not only reduce stress concentration and prevent damage to the protective net, but also disperse the force and enhance the compression and fixing effect.

[0040] In other embodiments, the pressure rod 21 and the insert 1 may be connected in other forms such as L-shape according to actual needs, which is not limited here.

[0041] Alternatively, if Figure 1 As shown, the handle 32 includes a handle body and connecting parts respectively connected to both ends of the handle body, and one end of the connecting part away from the handle body is connected to the connecting sleeve 31. The angle between the connecting part and the handle body is greater than or equal to 100° and less than or equal to 140°. The connecting part and the handle body are set to be connected at an obtuse angle of 100° to 140°, which is convenient for the staff to put their hands into the handle 32 for holding, improves comfort, is conducive to the staff's force application, and ensures the stability of the operation. The obtuse angle design can disperse the pressure of the handle 32 on the hand, making the pressure distribution more uniform.

[0042] Exemplarily, the angle between the connecting portion and the handle body is set to 135°.

[0043] The pressure rod 21 inserted into the connecting sleeve 31 extends in the first direction, and the insert 1 extends in the second direction. The size of the first rod segment 211 along the first direction is L1, the size of the second rod segment 212 along the first direction is L2, and the size of the insert 1 along the first direction is L3. The minimum distance between the two connecting sleeves 31 is S. By setting S<L1+L3 and S<L2+L3, the connecting sleeve 31 can be prevented from being separated from the pressure rod 21, ensuring the normal use of the fixing device and the fixing effect of the protective net.

[0044] Alternatively, if Figure 1 As shown, the insert 1 includes an insert rod 11 and a plug 12. The pressure rod 21 is arranged at the upper end of the insert rod 11. The length of the insert rod 11 is adjustable, and the required insertion depth can be flexibly selected according to the density of the ground, so as to ensure that there is sufficient fitting force between the fixed structure and the ground, thereby ensuring the fixing effect of the protective net. The plug 12 is arranged at the lower end of the insert rod 11. When fixing the protective net, the plug 12 of the insert 1 first passes through the protective net, and then is inserted into the ground for fixing. The cross-sectional area of ​​the plug 12 is set to gradually decrease from top to bottom, so that the insert 1 has a strong penetrating force, so that the insert 1 can quickly penetrate the protective net and be inserted into the ground, which is suitable for the penetration of various geological conditions and has strong versatility. In addition, after the plug 12 is inserted into the ground, it can be tightly embedded in the soil to form a more stable support structure, which helps to reduce the shaking and displacement of the insert 1 in the soil and ensure the compacting and fixing effect of the protective net.

[0045] By way of example, the plug 12 is provided as a tapered tip.

[0046] Optionally, the insertion rod 11 includes a first rod body and a second rod body. The pressure rod 21 is connected to the upper end of the first rod body, and the lower end of the first rod body is hollow. One end of the second rod body extends into the first rod body and is threadedly connected to the inner wall of the first rod body. The end of the second rod body away from the first rod body is connected to the plug 12. When the insert 1 is inserted into a relatively dense soil, the insert 1 only needs to be inserted in a shorter part to achieve fixation. The second rod body can be screwed into the first rod body to reduce the overall length of the insert 1. When the insert 1 is inserted into a relatively soft soil, part of the second rod body can be screwed out of the first rod body to increase the overall length of the insert 1, increase the insertion depth of the insert 1, enhance the fitting force between the fixing device and the ground, and ensure the compression and fixing effect of the protective net.

[0047] Optionally, the outer wall of the plug-in 1 is provided with an anchoring protrusion. Exemplarily, a plurality of rows of anchoring protrusions are arranged at intervals along the circumferential direction on the outer wall of the plug-in 1, and a plurality of anchoring protrusions in each row are arranged at intervals along the axial direction of the plug-in 1. By providing the anchoring protrusions, when the plug-in 1 is inserted into the ground, the contact area between the plug-in 1 and the soil is increased due to the presence of the anchoring protrusions, and the plug-in 1 can be more effectively embedded between the soil particles, thereby significantly improving the friction between the plug-in 1 and the soil and enhancing the stability of the plug-in 1. In addition, through the bite action between the anchoring protrusions and the soil, a certain locking effect can be formed, so that the plug-in 1 is inserted into the soil more firmly.

[0048] Exemplarily, the outer wall of the insert 1 is provided with 3 rows of anchoring protrusions along the circumferential direction, and 5 anchoring protrusions in each row are arranged at intervals along the axial direction of the insert 1. In other embodiments, 1 row, 2 rows, or more than 3 rows of anchoring protrusions may be provided according to actual needs, and 1 to 4, or more than 5 anchoring protrusions may be provided in each row, which is not limited here.

[0049] In this embodiment, the anchoring protrusion includes a fang-shaped protrusion. In other embodiments, the anchoring protrusion can also be set as a protrusion in a sawtooth shape or the like according to actual needs, which is not limited here.

[0050] Optionally, the clamping assembly 2 is rotatably connected to the insert 1. When the material is stacked on an inclined ground, the insert 1 is inserted below the ground until the clamping assembly 2 presses the protective net against the ground, and then the clamping assembly 2 is rotated to make the clamping assembly 2 fit completely against the ground, thereby enhancing the clamping and fixing effect of the clamping assembly 2 on the protective net.

[0051] For example, a spherical connector is provided at the upper end of the insert 1, and a spherical groove is provided on the side of the clamping assembly 2 facing the insert 1, and the spherical connector is rotatably clamped in the spherical groove. In other embodiments, a first connecting ear plate can be provided on the clamping assembly 2 according to actual needs, and a second connecting ear plate can be provided on the upper end of the insert 1, and the second connecting ear plate is rotatably connected to the first connecting ear plate through a rotating shaft, which is not limited here.

[0052] Embodiment 2

[0053] Based on the same inventive concept as that of the first embodiment, this embodiment provides a fixing device for a protective net.

[0054] like Figure 2 and Figure 3As shown, in this embodiment, the clamping assembly 2 includes two pressure rods 21. The two pressure rods 21 are vertical and cross-connected, that is, the two pressure rods 21 are cross-connected, and the upper end of the plug-in 1 is connected to the junction of the two pressure rods 21. When fixing the protective net, the two pressure rods 21 connected in a cross shape can simultaneously clamp and fix the protective net in four directions, ensuring the fixing effect, so that the protective net can more evenly disperse the external force it is subjected to, thereby improving the overall stability. In addition, the use of the cross-connected pressure rods 21 to clamp the protective net can also reduce stress concentration, prevent the protective net from being damaged due to stress concentration, and extend the service life of the protective net.

[0055] In some embodiments, according to actual needs, the two pressure rods 21 can be arranged to be at an acute angle and cross-connected, or the two pressure rods 21 can be arranged to be connected in a vertical T-shape, or any end of one pressure rod 21 can be connected to any end of another pressure rod 21, and the angle between the two pressure rods 21 is 0° to 90°, which is not limited here.

[0056] In other embodiments, more than two pressure rods 21 may be provided. All pressure rods 21 are distributed circumferentially, and all pressure rods 21 are connected to the upper end of the insert 1. By providing multiple pressure rods 21, the pressing and fixing effect of the pressing assembly 2 on the protective net can be enhanced, the firmness of the fixing of the protective net can be ensured, and the exposure of the material caused by the displacement of the protective net can be prevented.

[0057] Alternatively, if Figure 2 and Figure 3 As shown, the connecting sleeve 31 of the extraction member 3 is sleeved on one of the pressure rods 21, that is, the connecting sleeve 31 extends along the axial direction of the pressure rod 21, and a receiving groove (not shown in the figure) is provided on the other pressure rod 21. After the insertion member 1 is inserted into the ground, the handle 32 can be rotated to store the handle 32 in the receiving groove, so that the handle 32 is further fitted to the ground, preventing the raised handle 32 from tripping the staff and reducing safety hazards. In addition, the handle 32 can also be rotated out of the receiving groove to be in a raised state, so that it is convenient for the staff to pull the fixing device out of the ground.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
