Description

Technical Field

[0001] The present invention belongs to the field of construction and installation of building exterior protection structures, and more specifically, relates to a device and method for construction of building exterior protection and exterior decoration. Background Art

[0002] In the construction of building projects, in order to provide a working platform and protection for construction workers, external scaffolding is required. External scaffolding can effectively reduce the occurrence of falling accidents from heights. The existing forms of external scaffolding include ground-type external scaffolding, cantilevered external scaffolding and attached lifting scaffolding. There is a lot of installation and disassembly work for ground-type external scaffolding and cantilevered external scaffolding, and the installation and disassembly of external scaffolding is also accompanied by the occurrence of falling accidents from heights. The installation and disassembly work of attached lifting scaffolding is less, but it needs to use the main structure of the building as a fulcrum for climbing. After climbing, a large number of holes will be formed, which has a significant impact on the waterproofing of the building's exterior walls and the stress of the main structure.

[0003] During the construction phase of exterior decoration and renovation of buildings, hanging baskets are widely used as the main construction platform. The installation of hanging baskets requires professional equipment and technicians. During the installation process, it is necessary to ensure that the hanging points of the hanging baskets are firm and reliable, the wire ropes are properly tensioned, and safety devices such as safety locks are working properly. When shifting between different construction locations, the hanging basket needs to be lowered first, and then the hanging point position needs to be readjusted before it is raised. The operation process is complicated and prone to errors. During the construction process, since the hanging basket is in a high-altitude suspended state, it is affected by factors such as wind and construction vibration, and the stability of the hanging basket is poor. Moreover, when construction workers are working in the hanging basket, their space for movement is limited, and there is a lack of sufficient protective facilities around them. Once an accident such as the hanging basket shaking or the wire rope breaking occurs, the construction workers have almost no effective protective measures, and the risk of falling accidents from heights is extremely high.

[0004] In the field of building construction technology, many existing technologies have obvious deficiencies. Although some prefabricated building construction protection devices have been developed and applied, their structural design requires the indoor fixing mechanism and the outdoor protection mechanism to work together. This feature results in significant limitations in their use scenarios, and they can only be used under specific building structures and environmental conditions. In addition, during the installation and disassembly process, it is difficult to precisely match multiple components and complex operating procedures, which not only consumes a lot of manpower and material resources, but may also cause safety hazards due to improper operation. There is also a protection technology for the hanging basket of super-high-rise buildings. By adding an outer protective layer, it reduces the possibility of injuries to construction workers from objects above the protective layer to a certain extent. However, it ignores the risk of falling from heights caused by construction workers' own operating errors, hanging basket failures or bad weather during the construction of the hanging basket. This risk still poses a serious threat to the lives of construction workers.

[0005] In summary, the currently widely used building exterior protection and exterior decoration construction technologies and related patented technologies all show various defects and loopholes in actual construction projects, which cannot fully and effectively guarantee the safety and efficiency of the construction process, and it is also difficult to avoid adverse effects on the building structure such as local stress concentration and structural deformation.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Please refer to Figure 1 and Figure 2 , this embodiment provides a construction device for exterior protection and exterior decoration of a building, comprising: an exterior protection column assembly 2, a lifting mechanism 3 for supporting and lifting an exterior protection structure 6, and an exterior protection structure 6 sleeved on the exterior facade of the building to be decorated;

[0041] There are multiple external protective column assemblies 2, which are arranged on the ground at intervals outside the building according to the vertical projection position of the bottom contour of the external protective structure 6; the external protective column assembly 2 includes multiple standard sections 1 stacked in the vertical direction; the standard section 1 is a rectangular hollow cube structure, with columns arranged at the four corners, and multiple horizontal braces and diagonal braces arranged between the columns, which are connected to each other to form a stable cubic structure, and guide rails 21 are arranged on the diagonal columns.

[0042] The outer protection column assembly 2 is assembled from a plurality of standard sections 1, and is a vertical columnar structure as a whole, and the height can be adjusted according to the specific requirements of the construction. The protection column has a high straightness in the vertical direction. By using high-precision measuring instruments (such as laser collimators) for real-time monitoring and adjustment during the assembly process, the straightness deviation does not exceed 10mm / m, ensuring that the verticality of the entire protection column meets the installation and use requirements of the outer protection structure 6.

[0043] The standard section 1 is the basic component of the outer protection column assembly 2. The assembly of multiple standard sections 1 forms a protection column with sufficient height. In the outer protection column assembly 2, the connection between the standard sections 1 forms a continuous force transmission path, so that the outer protection column assembly 2 can withstand various loads transmitted from the outer protection structure 6, including the vertical deadweight, the weight of construction personnel and materials, and the horizontal wind load. The connection firmness of the standard section 1 directly determines the overall stability of the protection column, so the design of its connection method and connection structure is crucial.

[0044] The standard section 1 is in the form of a tube or frame, and its dimensions are determined according to the design requirements of the external protection column assembly 2. The main frame of the standard section 1 can be welded from profiles such as channel steel, I-beam or rectangular steel pipe. The welding process is strictly carried out in accordance with relevant standards, and the quality of the weld is subjected to non-destructive testing (such as ultrasonic testing, magnetic particle testing, etc.) to ensure that there are no defects inside the weld and the weld strength is not lower than the strength of the parent material.

[0045] The surface treatment of standard section 1 is crucial to its durability. The surface needs to be treated for corrosion, and processes such as hot-dip galvanizing and plastic spraying can be used. At both ends of standard section 1, there are interface structures specifically used for connection. The interface structure includes a connecting flange and a positioning structure. Bolt holes are evenly distributed on the connecting flange. The diameter tolerance of the bolt holes is controlled within ±0.05mm, and the center distance tolerance of adjacent bolt holes is within ±0.1mm to ensure accurate installation of the connecting bolts with adjacent standard sections 1. The positioning structure can be in the form of a positioning pin hole or a positioning boss. The diameter accuracy of the positioning pin hole can reach ±0.03mm, and the dimensional accuracy of the positioning boss is within ±0.1mm, ensuring that adjacent standard sections 1 can be quickly and accurately positioned during assembly.

[0046] Please refer to Figure 1 and Figure 3 , there are multiple jacking mechanisms 3, each of which is set on the outer protective column assembly 2, and is a cubic structure with a hollow inner cavity that matches the standard section 1. It is arranged around the standard section 1 of the protective column 2, and a matching guide device is arranged at the corresponding position of the guide track of the standard section 1 and can be lifted and lowered along the guide track 21; after all jacking mechanisms 3 are installed, the top ends are at the same horizontal height; the jacking mechanism 3 includes a power unit, a jacking execution unit, a control system and connecting components. Displacement and pressure sensors are arranged inside. The jacking structure is mainly composed of a power unit, a jacking execution unit, a control system and connecting components. The power unit is its core power source, and a hydraulic drive system or an electric mechanical drive system can be used. If it is a hydraulic drive system, it includes key components such as a hydraulic pump, a hydraulic cylinder, and a hydraulic valve. The hydraulic pump has high flow and high pressure output capabilities, and can provide a stable power source for the hydraulic cylinder to meet different jacking speed and load requirements. The hydraulic cylinder is used as an actuator, and its parameters such as piston diameter and stroke length are precisely designed. The piston diameter is determined based on the required lifting force, and the stroke length is adapted to the height of the standard section 1, ensuring that each lifting action can accurately install or remove a standard section 1. The cylinder has excellent sealing performance, which ensures the stability of the lifting process.

[0047] In addition to the hydraulic cylinder, the lifting actuator unit also includes a lifting frame connected to it. The lifting frame is fixed to the top of the outer protective column assembly 2 through a special connecting component, and its structural design ensures uniform force transmission. The lifting frame is made of high-strength steel and undergoes welding and heat treatment processes to meet strength and rigidity requirements. Its shape and size match the top structure of the outer protective column assembly 2, and it is connected to the outer protective column assembly 2 through multiple connection points. The connection points are reasonably distributed, which can effectively disperse the lifting force and prevent excessive local stress.

[0048] The control system is the "brain" of the jacking structure, which can achieve precise control of the jacking process. The control system has manual and automatic control modes. In the automatic control mode, the jacking and lowering operations can be automatically completed according to the preset program. The displacement, pressure and other parameters in the jacking process are monitored in real time through sensors installed on the jacking structure and the outer protective column assembly 2 (such as displacement sensors, pressure sensors, etc.). The displacement sensor has an accuracy of up to ±0.1mm and can accurately feedback the jacking height. The pressure sensor can accurately measure the jacking force. The control system adjusts the power unit in real time based on the data fed back by these sensors to ensure uniform jacking speed and stable jacking force, avoiding structural damage or safety accidents caused by excessive jacking speed or excessive jacking force.

[0049] The jacking structure 3 is closely related to the standard section 1. When installing the standard section 1, the jacking structure accurately places the new standard section 1 on the top of the installed outer protection column assembly 2 through precise jacking action, and ensures the installation position of the standard section 1 is accurate through the positioning device. When dismantling the standard section 1, the jacking structure also plays a key role. Through reverse jacking, the standard section 1 to be dismantled is separated from the adjacent standard section 1, and then it is safely removed. This operation requires the jacking structure to have high jacking height and force control accuracy to meet the installation and disassembly requirements of the standard section 1.

[0050] The jacking structure and the protective column are interdependent. The protective column provides an installation foundation and load-bearing support for the jacking structure, and its verticality and stability directly affect the working effect of the jacking structure. At the same time, the working state of the jacking structure will also affect the external protective column assembly 2. For example, during the jacking process, if the jacking force is uneven or the jacking speed is too fast, it may cause the external protective column assembly 2 to deform. Therefore, the jacking structure and the external protective column assembly 2 are designed with a reasonable connection and the synergy of the control system to ensure the mutual adaptability and stability of the two during the entire use process. In terms of connection, the connection between the jacking structure and the top of the external protective column assembly 2 is made by high-strength bolt connection and positioning pin cooperation. The specifications and preload force of the bolts are strictly calculated, and the accuracy of the positioning pin can reach ±0.05mm, ensuring a firm and accurate connection.

[0051] Please refer to Figure 1 and Figure 6-Figure 8, the outer protective structure 6 is installed on the upper end of all jacking mechanisms 3; the main body of the outer protective structure 6 includes a main beam 8, a column 9 and a cross bar 10; the bottom end of the main beam 8 is connected to the top of the jacking mechanism 3, and a plurality of columns 9 and a plurality of cross bars 10 are arranged on the main beam 8 and staggered in the horizontal and vertical directions to form a grid structure of not less than two layers; a horizontal cross bar 10 is arranged between each layer of adjacent grid structures to connect and fix. In some preferred embodiments, the above-mentioned grid structure can also be surrounded by a steel plate mesh 12 for enhancing safety and preventing falling, and the steel plate mesh 12 is in an oblique staggered grid shape and is connected and fixed to the grid structure. A protective ceiling 11 is also arranged on the top of the outer protective structure 6, and an openable window 13 is arranged in the middle of the protective ceiling 11.

[0052] Please refer to Figure 1 and Figure 5, the outer protective column assembly 2 is connected to the building 14 by an attached wall 5; the attached wall 5 includes a first vertical rod 51 and a second vertical rod 52, which are the main vertical support components of the attached wall structure and are made of high-strength alloy steel. They have excellent compression and bending resistance, ensuring that they can stably withstand various forces from the outer protective structure 6. The cross-sectional shape of the first vertical rod 51 and the second vertical rod 52 can be rectangular or circular, and they have undergone special surface treatment processes, such as passivation treatment, to enhance their corrosion resistance and extend their service life. The first cross bar 53 and the second cross bar 54 are precisely arranged between the first vertical rod 51 and the second vertical rod 52 to build a stable horizontal connection system. The left end of the first crossbar 53 is vertically connected to the upper end of the first vertical bar 51 by full penetration welding. The quality of the weld meets high-level welding standards, such as AWSD1.1 standard, to ensure the high strength and reliability of the connection. The right end is also connected to the upper end of the second vertical bar 52 by high-quality welding technology, and additional reinforcing ribs are added at the welding position. The thickness of the ribs is not less than 8mm, and the shape is triangular or trapezoidal, which effectively disperses stress concentration. The left end of the second crossbar 53 is connected to the middle of the first vertical bar 51 by high-strength bolts. Ordinary carbon steel bolts of M20 (such as grade 8.8) can be selected, and the preload force is accurately controlled at 250-300N·m. The right end is connected to the middle of the second vertical bar 52 by the same bolt connection method to form a stable middle connection node. The bottom end of the first diagonal brace 55 and the bottom end of the second diagonal brace 56 are on the same horizontal line as the bottom end of the first vertical bar 51 and the bottom end of the second vertical bar 52, to ensure uniform transmission and balanced distribution of force. The first diagonal brace 55 is designed to be in a unique 7-shaped shape, and is connected to the first vertical rod 51 at the upper left side of the bottom end by a special embedded connection method. A positioning groove and a tenon structure are provided at the connection point, and the matching accuracy of the groove and the tenon can reach ±0.03mm, thereby enhancing the stability and accuracy of the connection; the second diagonal brace 55 is in a 7-shaped shape, and is connected to the second vertical rod 51 at the upper right side of the bottom end by a similar high-precision connection method. The angle between the diagonal brace and the vertical rod is accurately calculated and optimized, and is between 30° and 60°, so as to achieve the best mechanical properties, effectively resist horizontal tension and pressure, ensure that the connection between the external protection structure 6 and the building 14 is firm and reliable, and can maintain the safety and stability of the external protection system under various complex working conditions, providing a solid guarantee for the external protection and external decoration construction of the building.

[0053] Please refer to Figure 1, the outer protective column assembly 2 is relatively arranged with a ladder cage 4 running vertically between the ground and the jacking mechanism 3. On the outside of the protective column, some auxiliary structures can be set for installing the connection points of the wall 5, and their position distribution is accurately planned according to the mechanical principle of the wall-attached structure and the layout of the main structure of the building. The protective columns are set at different height intervals, and the vertical spacing of adjacent connection points is usually between 3-6 meters. The specific value is determined according to factors such as the building height, the wind load borne by the external protective structure, and the size of the construction load. The connection point adopts the form of a combination of embedded grooves and protrusions. The groove depth is between 50-100 mm, and the protrusion height matches it. The matching tolerance of the two is controlled within ±2 mm to ensure that the wall-attached structure can be accurately docked during installation, achieve a firm and reliable connection, and effectively transfer the horizontal load of the external protective structure to the main structure of the building. At the same time, a reinforcing ring plate is set around the connection point. The thickness of the ring plate is not less than 8 mm and the width is between 100-150 mm. It is connected to the protective column using a full penetration welding process to further enhance the strength and stability of the connection point.

[0054] The attachment device installation position for fixing the ladder cage 4 is designed with full consideration of the running track and size specifications of the ladder cage. The installation position is in the shape of a rectangular or circular groove, the length and width of the rectangular groove are 10-20 mm larger than the corresponding dimensions of the ladder cage attachment device, and the diameter of the circular groove is 15-25 mm larger than the outer diameter of the ladder cage attachment device, so as to facilitate the smooth installation and adjustment of the ladder cage attachment device. A positioning pin hole is provided inside the installation position, and the pin hole diameter accuracy can reach ±0.05 mm. The positioning pin is precisely matched with the ladder cage attachment device to prevent the ladder cage from horizontal displacement during operation. In addition, reinforcing ribs are welded around the installation position, the thickness of the ribs is between 6-10 mm, and they are distributed in a triangular or trapezoidal shape. The number is determined according to the load and running speed of the ladder cage, generally 3-6 pieces, which effectively improves the bearing capacity and anti-deformation ability of the installation position, and ensures the stability and safety of the ladder cage when it runs vertically between the ground and the jacking mechanism 3. These auxiliary structures are integrated with the main structure of the protective columns. Their materials are the same as those of the protective columns. High-strength low-alloy structural steel, such as Q345B, is selected. They undergo rigorous processing and manufacturing techniques and quality inspection procedures to ensure that their quality and performance meet the strict requirements of exterior building protection and exterior decoration and renovation construction.

[0055] Workflow or principle method:

[0056] Step 1: Install the standard section 1 at a suitable position outside the building. The spacing of the standard section 1 in the horizontal direction should be able to meet the force requirements of the upper external protection structure 6. The assembly of the standard section 1 and the standard section 1 forms the external protection column assembly 2.

[0057] Step 2: Install the jacking mechanism 3, and install the main beam 8, the vertical pole 9, the horizontal pole 10, the protective ceiling 11 and the steel plate mesh 12 on the upper part of the jacking mechanism 3 to form an external protective structure 6.

[0058] Step 3: According to the progress of the main structure construction of the building, standard sections 1 are added section by section through the jacking mechanism 3 to meet the needs of external protection of the building construction.

[0059] Step 4: After the jacking reaches a certain height, the wall attachment 5 should be installed to ensure safety.

[0060] Step 5: After the main structure of the building is constructed to a certain height, a ladder cage 4 can be installed on the outer protective column assembly 2 to transport construction materials to meet the transportation needs of materials used for interior decoration of the building.

[0061] Step 6: After the main structure of the building is completed, the protective ceiling 11 of the outer protective structure 6 can be removed, and the standard section 1 can be removed section by section through the lifting mechanism 3. With the descent of the outer protective structure 6, the exterior decoration and renovation of the building can be completed from top to bottom.

[0062] Step 7: When the outer protective structure 6 is lowered to the bottom, the outer protective structure 6, the lifting mechanism 3 and the remaining standard sections 1 can be removed.

[0063] At the same time, in other preferred embodiments, a more advanced intelligent monitoring system can be integrated on the basis of the existing structure. For example, more types of sensors, such as wind speed sensors, temperature sensors, vibration sensors, etc., are added to key parts such as the standard section 1, the lifting mechanism 3, and the outer protective structure 6. These sensors can collect environmental and structural status data in real time and transmit them to the control system. The control system can thus achieve more refined operations, such as automatically adjusting the posture of the outer protective structure 6 or suspending the lifting operation according to the wind speed, and compensating for the thermal expansion and contraction of the structure according to temperature changes, further improving construction safety and structural stability.

[0064] The outer protective structure 6, the lifting mechanism 3 and the outer protective column assembly 2 can also be further modularized. Modules of different specifications and functions can be designed, such as standard section 1 modules of different sizes, lifting mechanism 3 modules with different lifting capacities, etc. Before construction, these modules can be flexibly selected and combined according to the specific building scale, height and construction requirements, so as to improve the adaptability and customizability of this patent in different projects.

[0065] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
