Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a mother-and-child climbing scaffold. Background Technology
[0002] Currently, most residential buildings in my country have an "I"-shaped floor plan, with connecting beams (not subject to load-bearing loads) between the open spaces of two units on the same side. Since not every floor has these connecting beams, those floors are considered "non-standard floors." When using climbing scaffolding, the design is often optimized based on the standard floor structure, but the obstacles posed by non-standard structures are frequently overlooked. During construction, the horizontal placement of non-standard structural components prevents the climbing scaffolding from reaching its designated position within the planned time. This necessitates partial dismantling of the existing climbing scaffolding before lifting it above the non-standard structural floor, and then reinstalling the dismantled components. This practice poses significant safety hazards, reduces construction efficiency, and increases costs. Utility Model Content
[0003] The purpose of this invention is to provide a mother-daughter climbing scaffold to solve the problems existing in the prior art. The mother and daughter climbing scaffolds can be raised synchronously without being obstructed by non-standard components. This is a construction operation that actively avoids obstacles. It helps to improve construction efficiency and does not affect the construction progress.
[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a mother-daughter climbing frame, including a mother climbing frame, a daughter climbing frame, and a platform flap. The mother climbing frame is installed on the outer contour of the building, and the daughter climbing frame is installed on the inner contour of the building. The layers of the mother climbing frame and the daughter climbing frame are arranged flush with each other.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The purpose of this invention is to provide a mother-daughter climbing scaffold to solve the problems existing in the prior art. The mother and daughter climbing scaffolds can be raised synchronously without being obstructed by non-standard components. This is a construction operation that actively avoids obstacles. It helps to improve construction efficiency and does not affect the construction progress.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1-5As shown, this utility model provides a mother-daughter climbing scaffold, consisting of a mother climbing scaffold 1, a daughter climbing scaffold 2, and a platform flap 4. Both the mother climbing scaffold 1 and the daughter climbing scaffold 2 are composed of scaffold uprights and a climbing scaffold lifting and wall-attaching device 3. The climbing scaffold lifting and wall-attaching system 3 is a mature technology in building climbing scaffolds, and is extensively described in existing patents, so it will not be elaborated upon here. The platform flap 4 is welded from checkered steel plates and angle iron. One end is detachably connected to the walkway of the daughter climbing scaffold 2 using steel hinges 9. During use, the platform flap 4 is placed horizontally, and the other end overlaps with the mother climbing scaffold 1. The purpose of using the mother and daughter climbing scaffolds working together is to avoid situations where non-standard structures (some components are not installed on every floor) exist on standard floors during lifting.
[0027] In one embodiment, the mother climbing scaffold 1 is installed on the outer contour of the building. Its uprights are made of square steel of Q335 or higher quality, with holes drilled in the square steel to connect to walkway panels. The walkway panels are made of square tubing on all four sides, with holes drilled in the square tubing at 100mm intervals. Bolts are used to connect the holes in the square tubing to the holes in the uprights, thus connecting the walkway panels to the uprights. Reinforcing members are added to the connection points between the square tubing and the square steel. These reinforcing members are welded from square tubing to form triangular members to enhance the node rigidity. They are installed on the underside of the walkway panels and the climbing scaffold uprights and fixed with bolts to form the frame structure.
[0028] In one embodiment, the sub-climbing scaffold 2 is installed on the inner contour of the building, flush with the parent climbing scaffold 1. Its uprights are made of square steel of Q335 or higher, with holes drilled in the square steel to connect to walkway panels. The walkway panels are made of square tubing on all four sides, with holes drilled in the square tubing at 100mm intervals. Bolts are used to connect the holes in the square tubing to the holes in the uprights, thus connecting the walkway panels to the uprights. Reinforcing members are added to the connection points between the square tubing and the square steel. These reinforcing members are welded from square tubing to form triangular members to enhance the node rigidity. They are installed on the underside of the walkway panels and the uprights of the climbing scaffold and fixed with bolts to form the frame structure.
[0029] In one embodiment, the platform flap 4 is made of angle iron, square tubing, and patterned steel plate. The bottom of the patterned steel plate is reinforced with ribs to increase rigidity. The platform flap 4 is installed between the separation points of the mother and daughter climbing frames 1, and can be assembled from one or more pieces. Multiple square tubing pieces are welded to the bottom of each patterned steel plate at equal intervals. One end of the platform flap 4 connects to the mother climbing frame 1 via angle iron overlapping the walkway plate and is bolted to the walkway plate of the mother climbing frame 1. The other end is bolted to the walkway plate of the daughter climbing frame via steel hinges 9. When the climbing frame is lifted, if it encounters a non-standard structure, the platform flap 4 can be opened upwards at 90°. At this time, the mother climbing frame 1 and the daughter climbing frame 2 are disconnected, allowing the platform to avoid obstructions from non-standard components and smoothly lift the climbing frame to the predetermined position according to construction needs. The platform flap 4 is fixed to the climbing frame uprights with pins to prevent the platform from suddenly tipping down due to swaying during lifting.
[0030] The construction steps of the mother-daughter climbing frame 1 in this utility model are as follows:
[0031] 1. Install the sub-climbing scaffold 2. Pre-assemble it in an open area of the construction site, within the reach of a tower crane or hoist. A starting frame should be erected in advance on the outside of the main structure 8 using steel pipe scaffolding for leveling. The assembly steps are as follows: first, install the uprights and walkway panels, securing them with bolts; then, install the triangular reinforcing members below the walkway panels at the connection point with the uprights; finally, install the climbing scaffold guide rails 6. After assembling the sub-climbing scaffold 2 to a height of 2 steps on the ground, use a tower crane to hoist it to the inner contour of the building. During construction, the sub-climbing scaffold 2 should be installed according to the construction progress of the main structure 8 until completion. External protective railings should be installed after each hoisting. Once the main structure 8 has been constructed to the 4th floor or higher (with pre-embedded wall attachment holes for each floor), and conditions are fully met for the climbing scaffold attachment, install the lifting system and guide rail wall supports, using the proprietary electrical control system for leveling. Ensure the electric hoist pulling force is the same at each lifting point.
[0032] 2. Install the mother climbing frame 1, and the installation steps are the same as those for the daughter climbing frame 2.
[0033] 3. Install platform flap 4. One side of platform flap 4 is welded to the walkway of sub-climbing frame 2 with steel hinges 9, so that the flap can flip up and down. The other end of platform flap 4 needs to be welded with an angle iron, L-shaped downward and outward, so that it can accurately rest on the walkway of the mother climbing frame 1 when flipped down. Platform flap 4 can be divided into several flaps according to the actual length of sub-climbing frame 2. Pins and pin holes are set on the end face of platform flap 4 facing the walkway on both sides. In addition, pin holes are also welded on the frame uprights of adjacent sub-climbing frame 2 for fixing platform flap 4 when flipped up.
[0034] 4. When lifting the climbing scaffold, if non-standard components are encountered ( Figures 1-4 The concrete component 5) can be manually flipped up before lifting. Pins are then inserted through the pin holes on the platform flipped up 4 to fix it to the uprights of the sub-climbing frame 2. Each walkway is equipped with a platform flipped up 4. The operator starts the lifting switch, and the main and sub-climbing frames 1 are lifted synchronously. After lifting to the correct position, the platform flipped up 4 is manually flipped down and placed on the main climbing frame 1 to provide the operator with a wider working surface. Simultaneously, the inner edge flipped up 7 is also flipped down and placed against the main structure 8 to prevent objects from falling from the edge.
[0035] 5. Dismantling of the climbing scaffold: Once the main structure (8) is topped out, the climbing scaffold is no longer needed. The scaffold can be dismantled into several units in the air, lowered by a tower crane, and then dismantled manually. The dismantling sequence is to dismantle the mother climbing scaffold (1) first, followed by the child climbing scaffold (2).
[0036] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
