Description

Technical Field

[0001] This application belongs to the field of building engineering safety protection, specifically involving a modular manhole cover based on waste recycling, with a waste material reuse rate of up to 90%. Background Technology

[0002] In the field of construction engineering, edge protection of well openings (such as pipe wells, elevator shafts, and reserved openings) is crucial. Currently used protection methods have significant drawbacks: while steel plates are sturdy, their purchase cost is high, and their weight makes moving, installing, and adjusting their position extremely inconvenient; prefabricated standardized fences, although highly standardized, also have a considerable initial cost, and their poor adaptability and lack of flexibility are prominent when faced with complex and varied well openings of different sizes on construction sites; while using scrap wood formwork, although inexpensive, has the fatal weakness of being susceptible to moisture deformation, decay, and aging, leading to a rapid decline in structural strength. Furthermore, it usually lacks conspicuous warning signs (such as colored strips or reflective strips), making it difficult to guarantee both protective performance and safety.

[0003] It is worth noting that construction sites often accumulate large amounts of resources considered "waste," such as leftover short steel bars, damaged formwork scraps, and used tires. These materials actually possess underutilized structural properties (such as the strength of the steel bars, the support of the formwork, and the elasticity and wear resistance of the tires). This presents an opportunity for innovative design of protective devices: if a specialized wellhead protection device can be designed whose core structure cleverly integrates and utilizes these waste materials, it can not only significantly improve the structural strength, durability, and warning effect of the protective device, but also achieve the goal of resource recycling by "turning waste into treasure." This solution can effectively overcome the shortcomings of existing protective measures, reduce procurement costs, and decrease construction waste, achieving both economic and environmental benefits. Utility Model Content

[0004] The purpose of this application is to provide a modular manhole cover based on waste recycling, which solves many shortcomings of existing protection methods and addresses the problem of waste recycling at construction sites.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A modular manhole cover based on waste recycling includes a waste steel mesh frame, a waste cover plate on the upper part of the waste steel mesh frame, a reflective warning layer on the upper surface of the waste cover plate, waste rubber on the outer periphery of the waste cover plate and the waste steel mesh frame, a waste steel handle on the waste cover plate, a waste steel hook on the lower part of the waste steel mesh frame, and a waste counterweight bucket hanging on the waste steel hook.

[0007] Furthermore, the discarded cover plate is made of discarded plywood.

[0008] Furthermore, the reflective warning layer is a reflective paint or a reflective film.

[0009] Furthermore, the waste steel mesh frame is made of welded transverse and longitudinal steel bars.

[0010] Furthermore, one side of the waste steel mesh frame is provided with connecting steel bars extending out of the waste cover plate, and a connecting sleeve is provided on the side of the waste steel mesh frame adjacent to or opposite to the connecting steel bars.

[0011] Furthermore, the waste rubber is in strip form and is fixed to the waste cover plate with nails.

[0012] Furthermore, the waste cover plate has two handle openings, and the waste steel bar handle has an inverted U-shaped structure. The two ends of the inverted U-shape of the waste steel bar handle pass downward through the two handle openings respectively, and both ends of the inverted U-shape of the waste steel bar handle are provided with bent parts for locking the waste cover plate.

[0013] Furthermore, the upper end of the waste steel bar hook is wrapped around the steel bar of the waste steel bar mesh frame, and the lower end of the waste steel bar hook is hook-shaped.

[0014] Furthermore, the waste steel bar hook includes a first hook and a second hook arranged diagonally.

[0015] Furthermore, the waste counterweight bucket includes a bucket body containing waste residue, and a pull rope is provided between the two ends of the bucket body opening, with the pull rope being hung on a waste steel bar hook.

[0016] Furthermore, the bucket is a waste paint bucket.

[0017] The beneficial effects of this application are:

[0018] 1. Significant environmental benefits: Waste comprehensive utilization rate ≥90%, reducing construction waste.

[0019] 2. High construction efficiency and adaptability: Modular design, easy to install and dismantle, flexible size, can be used for protection of different wellhead sizes.

[0020] 3. Enhanced safety performance: Multiple protection mechanisms (fall prevention): The composite structure of steel mesh and waste wood can withstand concentrated loads ≥200kg / m. 2 To prevent accidental falls; the anti-slip and scratch-resistant rubber strip edge design eliminates the risk of injury from sharp steel bar edges; it is wind-resistant and stable, with a certain self-weight, and the counterweight bucket fixes the cover plate by gravity to prevent it from being blown away by the wind; the highly visible reflective stickers have a nighttime visibility distance of up to 50m, enhancing nighttime warnings.

[0021] 4. Economic efficiency throughout the entire life cycle: Utilizing construction site waste saves material costs; maintenance costs are extremely low. When wooden boards or rubber strips are damaged, they can be partially replaced without the need for complete scrapping, and can be repeatedly recycled.

[0022] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

Detailed Implementation

[0027] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0028] refer to Figures 1-3 As shown, a modular manhole cover based on waste recycling includes a waste cover plate 1, a waste steel mesh frame 2, waste rubber 3, a waste steel handle 4, a waste steel hook 5, and a waste counterweight bucket 6.

[0029] The abandoned steel mesh frame 2 serves as the structural skeleton for load-bearing. The upper part of the abandoned steel mesh frame 2 is equipped with an abandoned cover plate 1, which also serves as a shielding panel for load-bearing. The mesh frame and the cover plate together form the main load-bearing structure, which has both good load-bearing capacity and a complete shielding surface, so that personnel, equipment and tools will not fall into the well.

[0030] The upper surface of the abandoned cover plate 1 is equipped with a reflective warning layer to improve the warning effect of the cover plate at night. The outer perimeter of the abandoned cover plate 1 and the abandoned steel mesh frame 2 is equipped with abandoned rubber 3. The anti-slip and anti-scratch rubber strip edge design protects the cover plate from all sides and can also eliminate the risk of injury from the sharp edges of the steel bars.

[0031] The waste cover plate 1 is equipped with a waste rebar handle 4 for easy lifting and carrying of the entire cover plate. The lower part of the waste rebar mesh frame 2 is equipped with waste rebar hooks 5 for hanging and placing the counterweight bucket. The waste counterweight bucket 6 is hung on the waste rebar hooks 5 to increase the overall weight and prevent the entire structure from being blown away by the wind. Ideally, the counterweight bucket should be located in the center to ensure stability.

[0032] The waste cover plate 1 is made of waste plywood with a thickness of 13-18mm, realizing the reuse of waste templates, while having good supporting strength. The reflective warning layer is reflective paint or reflective film. The reflective paint is obtained by brushing on black and yellow paint, and the reflective film is obtained by direct pasting.

[0033] The waste steel mesh frame 2 is made of horizontal steel bars 201 and vertical steel bars 202 welded together. The mesh unit is made of waste steel bars with a diameter of not less than Φ12mm and welded into 800×800mm grid units (which can also be adjusted according to the site conditions). The grid intersections are fixed by spot welding to ensure the rigidity of the frame.

[0034] One side of the waste steel mesh frame 2 is provided with a connecting steel bar 203 extending out of the waste cover plate 1. The side of the waste steel mesh frame 2 adjacent to or opposite to the connecting steel bar 203 is provided with a connecting sleeve 204. The connecting steel bar 203 of one cover plate is inserted into and fixed in the connecting sleeve 204 of another cover plate to realize the splicing and expansion of the cover plate. It can be used for protection of different well opening sizes.

[0035] The connecting steel bars on one side of each adjacent frame extend by at least 150mm, serving as insertion rods for connecting to the other module. This involves welding a steel pipe at least 150mm long to one side, with the inner diameter of the pipe not less than the diameter of the reinforcing steel bars in the grid frame. This steel pipe acts as a socket for connecting to the insertion rods of the other module, forming a larger protective grid frame. The minimum length limit for the insertion rods is primarily to prevent them from becoming too short and potentially detaching after the two modules are connected. Through the socket connection combination between modules, openings ranging from 800mm to 1600mm can be protected.

[0036] Waste rubber 3 is in strip shape, cut from waste tires into 50mm wide strips. Waste rubber 3 is fixed to the waste cover plate 1 with nails to achieve a barrier and protection between the inside and outside.

[0037] Two handle openings 101 are provided on the waste cover plate 1. The waste rebar handle 4 has an inverted U-shaped structure, with both ends of the inverted U-shape passing downwards through the two handle openings 101. Both ends of the inverted U-shape of the waste rebar handle 4 are provided with bent portions to engage with the waste cover plate 1. Under the action of gravity, the handle retracts into the cover plate without forming an obstructive structure. When it is necessary to lift the cover plate, the handle is pulled out and engaged through the bent portions, allowing the entire cover plate to be operated through the handle.

[0038] The upper end of the waste steel bar hook 5 is wrapped around the steel bars of the waste steel bar mesh frame 2, and the lower end of the waste steel bar hook 5 is hook-shaped (i.e., J-shaped), so as to achieve a good transition between the hook and the counterweight bucket. The waste steel bar hook 5 includes a first hook 501 and a second hook 502 arranged diagonally, thus forming two hanging points and ensuring that the center of gravity is located in the center, so as to maintain the stability of the counterweight bucket.

[0039] Whether to add counterweight can be determined based on the usage environment. The waste counterweight bucket 6 includes a bucket body 601, waste residue 602, and a pull rope 603. The bucket body 601 is a 20L waste paint bucket, specifically made of plastic. The waste residue 602 is located inside the bucket body 601, specifically filled with a mixture of waste soil or broken bricks and waste mortar blocks.

[0040] A pull rope 603 is provided between the two ends of the opening of the bucket body 601, and the pull rope 603 is hung on the scrap steel bar hook 5. The handle of the bucket is replaced with a rope, and the rope is cut to a suitable length according to the size and shape of the bucket. Ensure that the rope is long enough to be hung on the hook under the lid.

[0041] The workflow of this application is as follows: Step 1: Weld the steel mesh. Step 2: Cover and secure the wooden board, then apply reflective warning paint or affix reflective warning film. Step 3: Use one protective device or assemble multiple protective devices according to the size of the opening requiring protection. Step 4: Install edge rubber strips. Step 5: Suspend the counterweight bucket. For a single protective plate, the counterweight bucket is suspended in the middle. After the protective plates are assembled, the counterweight bucket is suspended on the hooks of the diagonal protective plates to avoid eccentric force.

[0042] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
