Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction, and in particular to a slope reinforcement and fixing device for building and municipal civil engineering. Background Technology

[0002] Slope stabilization refers to improving the stability of slopes (such as natural slopes and excavated slopes) through engineering measures to prevent disasters caused by soil slippage, collapse, or rock fragmentation.

[0003] Existing technologies for slope stabilization devices mostly employ rigid supports or single protective net structures, which have significant shortcomings: First, traditional devices have a fixed coverage area and cannot be flexibly adjusted according to the length and height of the slope, resulting in material redundancy or blind spots. This is especially problematic in complex terrains such as stepped or curved slopes, where they struggle to fit snugly against the slope surface, making them prone to rockfall due to gaps in localized protection. Second, the protective structures lack sufficient impact resistance. Rigid supports are prone to stress concentration and breakage under the impact of falling rocks, while flexible nets, lacking a load-distribution mechanism, are susceptible to localized overload damage, requiring frequent replacement and maintenance. These problems lead to poor adaptability, high maintenance costs, and may even exacerbate the risk of slope instability due to protective failure.

[0004] Therefore, there is an urgent need to propose a slope reinforcement and fixing device for building and municipal civil engineering to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a slope reinforcement and fixing device for building and municipal civil engineering.

[0006] The technical solution is as follows: A slope reinforcement and fixing device for building and municipal civil engineering, comprising a first fixing frame, a second fixing frame, mounting plates, rivets, connectors, a protective net cover, fixing plates, screws, and a winding roller. The first fixing frame is a fence structure with several equidistant trusses. The second fixing frame is slidably installed on the upper part of the first fixing frame. The second fixing frame has a truss design corresponding to the fence structure of the first fixing frame. Mounting plates are symmetrically arranged on the sides of both the first and second fixing frames. Each mounting plate has rivets with sharp lower parts inside. The upper edges of the first fixing frame are... Multiple symmetrical mounting slots are provided, and each mounting slot is fitted with a connector. The side of the connector has a protrusion, which connects to the mounting slot of the next first fixed frame to form a docking installation between the frames. A protective net is rolled up on the inner side of the second fixed frame. One end of the protective net is pulled to the inner side of the first fixed frame. A fixing plate is provided on the inner side of the first fixed frame. The fixing plate is pressed above the pulling part of the protective net. Several symmetrical screws are threaded through the fixing plate and the first fixed frame. The roll of the protective net is fitted with a take-up roller. Both ends of the take-up roller rotate through the outside of the second fixed frame.

[0007] As an improvement to the above scheme, each truss of the first fixed frame has an inwardly recessed groove.

[0008] As an improvement to the above solution, the protective netting has a diamond-shaped woven structure.

[0009] As an improvement to the above solution, it also includes slide bars. Slide bars are symmetrically arranged on each truss of the second fixed frame. The slide bars match the corresponding slide grooves to assist the sliding connection between the first fixed frame and the second fixed frame.

[0010] As an improvement to the above solution, a guide roller is also included. A guide roller is rotatably installed on the lower inner side of the second fixed frame, and the guide roller makes rotatable contact with the upper surface of the protective net cover.

[0011] As an improvement to the above solution, a torsion spring is also included, with a torsion spring provided between the protrusions at both ends of the take-up roller and the second fixed frame.

[0012] This utility model has the following advantages: The first fixed frame side connector is used to horizontally embed adjacent units, and the second fixed frame slides longitudinally to adjust the coverage height. With the help of the winding roller, the diamond-shaped protective net is released. The deformation of the mesh absorbs the impact kinetic energy and disperses it to multiple anchor points. Combined with rivet anchoring and torsion spring pre-tightening, it realizes modular expansion, overload resistance and low-cost maintenance, and adapts to the needs of complex slope protection.

[0020] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0021] Example: A slope reinforcement and fixing device for building and municipal civil engineering, such as Figures 1-6 As shown, the device includes a first fixing frame 1, a second fixing frame 2, a mounting plate 3, rivets 4, connectors 6, a protective net cover 7, a fixing plate 8, screws 801, and a winding roller 10. The first fixing frame 1 is a fence structure with several equidistant trusses. The first fixing frame 1 serves as the main support structure of the device. Through the fence-type truss design, it conforms to the slope surface to provide basic stability. The first fixing frame 1 is made of carbon structural steel or stainless steel, taking into account both strength and weather resistance. Each truss of the first fixing frame 1 has an inwardly recessed groove 101. A second fixing frame 2 is slidably installed on the first fixing frame 1. The second fixing frame 2 is made of the same material as the first fixing frame 1 to ensure structural consistency. The second fixing frame 2 has a truss design that corresponds to the fence structure of the first fixing frame 1. Mounting plates 3 are symmetrically arranged on the sides of both the first fixing frame 1 and the second fixing frame 2. Each mounting plate 3 has a rivet 4 with a sharp lower part inside. The tip of the rivet 4 is designed to penetrate hard soil layers to enhance pull-out resistance. The mounting plate 3 serves as an anchoring base, and the frame is fixed to the slope soil layer by the rivets 4. Multiple pairs of rivets are opened at each edge of the upper part of the first fixing frame 1. The mounting slots 5 are milled grooves, and each mounting slot 5 contains a connector 6. The mounting slots 5 and connectors 6 mate to laterally connect adjacent units, forming a modular expansion. The connector 6 has a protrusion on its side, which connects to the mounting slot 5 of the next first fixing frame 1 to form a butt joint installation between the frames. The connector 6 is fixed to the edge of the first fixing frame 1 by welding or bolts. The inner side of the second fixing frame 2 is covered with a protective mesh cover 7. The protective mesh cover 7 has a diamond-shaped woven structure and can be made of high-strength steel wire. The joints are hot-dip galvanized for corrosion protection. The protective net cover 7 absorbs the impact energy of the rolling stones through plastic deformation and distributes the load to multiple anchor points. One end of the protective net cover 7 is pulled to the inner side of the first fixed frame 1. A fixed plate 8 is provided on the inner side of the first fixed frame 1. The fixed plate 8 is pressed on the upper part of the pulling part of the protective net cover 7. Several symmetrical screws 801 are threaded through the fixed plate 8 and the first fixed frame 1. The drum of the protective net cover 7 is fitted with a take-up roller 10 through a bushing. The take-up roller 10 is rigidly connected to the drum of the protective net cover 7 through a keyway or pin. The two ends of the take-up roller 10 rotate through the outside of the second fixed frame 2.

[0022] like Figure 6 As shown, it also includes a slide bar 201. Slide bars 201 are symmetrically arranged on each truss of the second fixed frame 2. The slide bar 201 matches the corresponding slide groove 101 to assist the sliding connection between the first fixed frame 1 and the second fixed frame 2. The slide groove 101 is used to slide and engage with the slide bar 201 to form a low-resistance sliding pair to realize longitudinal height adjustment.

[0023] like Figure 3 and Figure 4 As shown, it also includes a guide roller 9. The guide roller 9 is rotatably installed on the lower inner side of the second fixed frame 2. The guide roller 9 rotatably contacts the upper surface of the protective net cover 7. The guide roller 9 reduces the frictional resistance when the protective net cover 7 is unfolded, and avoids scratching the net body.

[0024] like Figure 4 and Figure 5 As shown, it also includes a torsion spring 11. The torsion spring 11 is provided between the protrusions at both ends of the take-up roller 10 and the second fixed frame 2. The take-up roller 10 is used to store and release the net cover, and is pre-tightened with the torsion spring 11 to prevent loosening.

[0025] During installation, the first fixing frame 1 is attached to the slope surface with a fence-type truss structure. Its bottom is anchored to the rivet 4 through the mounting plate 3. The sharp rivet 4 inside the mounting plate 3 is driven vertically into the slope soil layer by a hydraulic hammer. Adjacent first fixing frames 1 are quickly engaged with the mounting groove 5 through the protrusion of the connector 6 to form a continuous horizontal coverage and realize modular expansion. The second fixing frame 2 engages with the sliding groove 101 of the first fixing frame 1 through the sliding strip 201 on the truss. It slides longitudinally along the slope surface by manual or mechanical traction to adjust the coverage height. After the second fixing frame 2 slides to the target position, it is anchored to the rivet 4 through the mounting plate 3 to prevent displacement.

[0026] When the protective net cover 7 needs to be released, the second fixed frame 2 can be pulled horizontally by a traction device (such as a winch or manual winch) to slide along the slide 101 towards the top of the slope. The winding roller 10 rotates synchronously with the movement of the second fixed frame 2, releasing the wound diamond-shaped woven protective net cover 7 to cover the slope. During the unfolding of the protective net cover 7, the guide roller 9 on the inner side of the second fixed frame 2 rolls into contact with the net cover, which can reduce friction loss during the unfolding process and provide guidance. After the protective net cover 7 is fully unfolded, the second fixed frame 2 is anchored to the rivet 4 by the mounting plate 3. At the same time, the screw 801 in the first fixed frame 1 squeezes the fixing plate 8 and uses friction clamping force to fix the end of the protective net cover 7 to form an anchor point. When the rolling stone impacts, the net cover disperses the impact force through the plastic deformation of the diamond mesh and transfers the load to the anchor point of the rivet 4 of the first fixed frame 1 and the adjacent module to avoid local overload.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
