Description

Technical Field

[0001] The invention belongs to the technical field of construction methods, and in particular relates to a scaffold-free construction system for installing a pool wall. Background Art

[0002] In modern construction and water conservancy projects, water pools, as an important infrastructure, are widely used in various places, such as swimming pools, reservoirs, sewage treatment pools, etc. The construction of water pools involves multiple links, including foundation excavation, steel bar binding, formwork installation, concrete pouring, waterproofing, etc. In particular, during the construction of the pool wall and pool bottom, a large amount of high-altitude operations are involved, which puts higher requirements on the construction method. A water pool refers to a structure used to store water or other liquids, and is widely used in the fields of construction, water conservancy, and municipal administration. It can be indoor or outdoor and used for a variety of purposes, such as swimming pools, reservoirs, landscape pools, sewage treatment pools, etc. The pool wall refers to the side wall part of the pool, which is used to enclose and support the water or other liquids in the pool. Scaffold-free refers to a construction method that does not require the use of traditional scaffolding during the construction process. This method replaces the role of scaffolding through other equipment or technical means to improve construction efficiency and safety.

[0003] In the traditional pool wall installation construction process, the following problems are usually encountered: The internal space of the pool is relatively closed, especially in large pools, the narrow internal space brings great inconvenience to the construction. The traditional construction method requires a large number of scaffolding to be built inside the pool to provide a working platform and passage. However, this practice not only takes up a lot of space, but also affects the normal progress of other processes. The waterproof performance of the pool is crucial, and the design of any embedded fixing points must take into account the waterproof requirements. The traditional construction method often requires embedded fixing points inside the pool to fix the scaffolding or supporting structure. However, this method of embedded fixing points will destroy the waterproof layer of the pool, causing problems such as leakage. The construction of the pool wall usually needs to be carried out at high altitudes, and the space inside the pool is relatively limited, which greatly increases the difficulty of construction. The traditional scaffolding erection requires a lot of manpower and time, especially when working at high altitudes, the operators need to climb the scaffolding frequently, which increases the difficulty of construction and safety hazards.

[0004] Disadvantages of the traditional scaffolding-free construction system for pool wall installation: The traditional scaffolding construction method is inefficient, especially in the construction of large pools, where the erection and dismantling of the scaffolding takes a lot of time and manpower. In addition, due to the presence of the scaffolding, other processes (such as concrete pouring, waterproofing, etc.) also need to bypass the scaffolding, further affecting the construction efficiency. The use of scaffolding inside the pool increases the safety risk of construction. When workers climb and work on the scaffolding, they are prone to accidents such as falls and collisions. In addition, the stability of the scaffolding is also a major problem. Once it becomes loose or collapses, it will bring serious safety hazards to the workers. The presence of the scaffolding occupies valuable internal space, making the already narrow pool even more crowded. This not only affects the convenience of construction, but may also cause other processes to fail to proceed normally, further affecting the progress of the entire project. Summary of the invention

[0005] In view of this, the present invention provides a scaffolding-free construction system for installing a pool wall, which solves the problem of limited space caused by the inability to pre-embed fixed points due to waterproofing requirements during pool construction, and improves construction efficiency by providing a safe and reliable working channel and operating platform through the use of a hanging ladder cage system.

[0006] The present invention is achieved in that:

[0007] The present invention provides a scaffold-free construction system for installing a pool wall, which comprises a hanging ladder cage, wherein the hanging ladder cage comprises a vertical ladder, a horizontal support, an operating hanging cage and a fixing device, wherein the vertical ladder comprises a plurality of connectable ladder segments, each of the ladder segments is connected by bolts or fixed by welding, the hanging ladder cage forms a vertical channel, the vertical ladder is arranged in the vertical channel by top suspension, the horizontal support is welded to the side of the vertical ladder close to the pool wall, the horizontal support comprises at least one pair of parallel support rods, one end of the support rod is welded to the vertical ladder or fixedly connected by bolts, and the other end is fixed to the pool wall, the fixing device comprises a tension safety clip and a top hanging point, and the top hanging point is fixed to the top structure of the pool by drilling holes and using expansion bolts.

[0008] The vertical channel refers to the vertical space where the hanging ladder cage is located. The vertical ladder is installed in the vertical channel and fixed by top suspension to ensure the stability of the vertical ladder.

[0009] The top suspension and horizontal support ensure the structural stability of the vertical ladder and improve the safety of the entire system. The work cage provides a safe and reliable working environment for operators and reduces the risk of operation. The horizontal support enhances the structural stability of the vertical ladder and prevents it from shaking during use. The top hanging point is fixed by expansion bolts to ensure the structural stability of the vertical ladder. The tension safety clip increases the fixing effect of the vertical ladder and prevents it from loosening during use.

[0010] On the basis of the above technical solution, the scaffold-free construction system for installing the pool wall of the present invention can also be improved as follows:

[0011] In which, the horizontal support is provided with an adjustment mechanism, which is used to adjust the length of the horizontal support. The adjustment mechanism includes one or more telescopic segments, each of which is composed of two inner and outer tubular components, including an outer tube and an inner tube. The outer tube is sleeved on the outside of the inner tube, and an adjustment bolt is provided between the outer tube and the inner tube. The extension and contraction of the telescopic segment are controlled by rotating the adjustment bolt.

[0012] The beneficial effects of adopting the above improved scheme are: the adjustable horizontal support can adapt to different widths of pool walls, thereby increasing the applicability of the system. By adjusting the bolts or knobs, the length of the horizontal support can be quickly adjusted, thereby simplifying the installation and adjustment process.

[0013] Furthermore, the pulling safety clamp includes two symmetrical clamps, which are connected by springs. One end of the clamp is fixed to both sides of the vertical ladder, and the other end is provided with an outwardly protruding hook structure. The hook structure grasps the edge of the vertical ladder through the tension of the spring.

[0014] The beneficial effects of adopting the above improved solution are: the clamping plate and the hook structure connected by the spring enhance the fixing effect of the pull safety clip. The design of the pull safety clip improves the fixing stability of the vertical hanging ladder.

[0015] Furthermore, the work cage is connected to the vertical ladder by a rope, one end of the rope is fixed to the vertical ladder, and the other end is connected to a buckle on the work cage, and the buckle is designed as a quick-release buckle, and a spring locking device is arranged below the quick-release buckle, and the spring locking device includes a spring and a tongue, and the spring is located below the tongue, and the tongue is tightened by the pressure of the spring, and a manual locking button is arranged on the quick-release buckle, and the manual locking button is located on one side of the quick-release buckle, and the buckle is locked by manual operation, and the front end of the tongue is designed to be an inclined angle, so as to facilitate insertion into the bayonet of the vertical ladder; the rear end of the tongue is designed to be a right angle or a barb to prevent it from falling out.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the quick-release buckle makes it easier to adjust the height of the working cage, thereby improving the working efficiency. The fixing effect of the working cage is ensured by connecting the rope and the buckle.

[0017] Furthermore, the vertical ladder has multiple fixing points, which are distributed at different heights of the vertical ladder. The fixing points are fixed by welding or bolting. One end of the fixing point is connected to the vertical ladder, and the other end is provided with a locking mechanism. The locking mechanism is composed of two inner and outer tubular components. The outer tube is sleeved on the outside of the inner tube, and an adjusting bolt or knob is provided between the inner and outer tubes.

[0018] The fixed points are distributed at different heights of the vertical ladder at a certain interval, usually 1 to 2 meters, and are adjusted according to the actual working height requirements.

[0019] Multiple fixing points can be adjusted according to the needs of operations at different heights, which improves the flexibility and adaptability of the system. The setting of the fixing points allows the operation cage to be quickly adjusted to the required height, making it convenient for operators to operate at different heights.

[0020] Furthermore, a reinforcing rib is provided at the bottom of each ladder segment, and the reinforcing rib is vertically welded to the ladder segment.

[0021] Furthermore, the working cage is welded from square steel pipes to form a rectangular frame structure, and a fence is arranged around the rectangular frame structure. The working cage has an opening design, and the opening is arranged on one side of the working cage, and the opening is used for workers to enter and exit.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the rectangular frame structure and the fence net provide effective safety protection for the operators and reduce the operation risks. The frame structure formed by welding the square steel pipes has high strength and stability.

[0023] Furthermore, the rope is a high-strength nylon rope or a steel wire rope.

[0024] Furthermore, each of the ladder sections of the vertical ladder is provided with steps, and the steps are provided with anti-slip patterns or anti-slip strips.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the anti-slip pattern or anti-slip strip increases the friction during climbing and reduces the risk of slipping. The anti-slip design improves the safety performance of the vertical hanging ladder.

[0026] Furthermore, a visual work assistance system is installed inside the work cage, including a camera, a display screen and a controller. The camera is installed on the top of the work cage, and the display screen is arranged inside the work cage. The camera and the display screen are installed in an integrally encapsulated shell, and the camera and the display screen are connected to the controller by wire.

[0066] 1. According to the construction needs, determine the required length and quantity of the hanging ladder cage. Taking the construction of the sewage treatment station of the high-end agricultural equipment intelligent manufacturing project as an example, the required hanging ladder length is 6 meters and the quantity is 4;

[0067] 2. Purchase 40 carbon rectangular tube materials, 20 round steel and other materials according to the length and quantity of the ladder cage;

[0068] 3. Make hanging racks, ladder cages and safety accessories;

[0069] 4. Purchase fall arresters, large ropes, expansion bolts and other preventive materials.

[0070] 5. Personnel preparation:

[0071] (1) The installation of the hanging ladder cage and the sewage tank is a high-altitude operation, which requires that the operators must pass the physical examination of a Class II or above hospital, have no hypertension, heart disease, or uncontrollable mental illness, etc. The operators must be over 18 years old and under 45 years old, and be able to adapt to high-altitude operations;

[0072] (2) Personnel shall be assigned to assist in the installation of each set of cage brackets, and only one person is allowed to work on the same cage bracket at the same time;

[0073] (3) Operators must undergo project safety education and safety technical briefings by special engineers.

[0074] Hanging rack ladder cage production:

[0075] 1. Production of vertical hanging ladder:

[0076] The vertical ladder of the hanging ladder cage is made of 40 carbon rectangular tubes. Taking the sewage treatment pool of Frontier Science and Technology City as an example, the vertical ladder is 6 meters long. In order to reduce the overall weight of the ladder, the ladder step is 40 cm, and the top of the ladder uses 20 round steel for suspension support. Two horizontal cross braces are set every 2 meters in the horizontal direction of the ladder, with a length of 30 cm.

[0077] 2. Hanging cage production:

[0078] The entire ladder cage is made of 40 carbon rectangular tubes with a size of 50 cm × 50 cm × 50 cm. The top of the ladder cage is made of 20 round steel hooks as shown in the figure. The bottom is made of 40 carbon rectangular tubes to set up two horizontal supports.

[0079] 3. Production of safety accessories:

[0080] The fall arrester is purchased as a finished product according to the working height;

[0081] Back pull anti-slip hook. Use 20 round steel for welding, size is 25cm wide and 40cm long.

[0082] Installation of rack ladder cage:

[0083] 1. Vertical ladder installation. First, use a pistol drill to drill two round holes with a depth of no less than 3cm and a diameter of 2cm at the ladder installation location above the construction pool according to the size of the ladder hook for hanging the ladder. Figure 3 As shown. Two installation workers tie large ropes to the two sides of the bottom of the ladder and cooperate with the other two workers to lift the ladder from the top to the hanging position. Four workers cooperate to hang the ladder to the designated position, as shown. Figure 4 As shown.
