[0024] Example

[0025] This embodiment provides a cornice aluminum plate construction system, such as Figures 1 to 3 As shown, it includes a sliding track 1 and a construction platform 2. The sliding track 1 is connected to the secondary purlin of the canopy and arranged along the axial direction of the eaves. The construction platform is slidably connected to the sliding track 1. The top of the construction platform 2 is located below the eaves and is inclined along the inclination direction of the eaves. The construction platform 2 is provided with a storage platform 3 near the indoor side. After the finished steel frame is installed on the ground, it is transported to the storage platform 3. The construction platform 2 slides along the sliding track 1 to the installation position, achieving the purpose of efficient and fast installation of the curtain wall eaves frame and aluminum plate under complex conditions, and successfully solving the defects of no mechanical construction surface, narrow working surface, high construction difficulty, and high construction precision requirements.

[0026] In this embodiment, the sliding track 1 is made of a hot-dip galvanized square tube, and a pair of the hot-dip galvanized square tubes are arranged at intervals to serve as installation limit for the construction platform 2.

[0027] In this embodiment, the storage platform 3 arranged on the indoor side of the construction platform 2 can not only store the finished steel frame, but also serve as a counterweight to prevent the construction platform 2 from accidentally falling to the ground, thereby enhancing the safety performance of the construction platform 2.

[0028] In this embodiment, the construction platform 2 includes a roller 21, which is slidably connected to the sliding track 1. A plurality of the rollers 21 are arranged at intervals, and a frame 22 fixedly connected to the rollers 21 is arranged above the plurality of rollers 21. The top of the frame 22 is stepped, and is gradually lowered from the raised end of the eaves to the indoor end, so as to facilitate the construction workers to install the eaves structure.

[0029] In this embodiment, the roller 21 includes a roller 211 , which is slidably connected to the sliding track 1 , a pair of the rollers 211 are respectively arranged on a pair of hot-dip galvanized square tubes, and the pair of rollers 211 are connected to each other through a first connecting rod 212 .

[0030] In this embodiment, a second connecting rod 23 for connecting to the first connecting rod 212 is provided at the bottom of the frame 22, and a guardrail 24 is provided around the top to prevent construction workers from falling from the frame 22. The height of the guardrail 24 decreases as the height of the top of the frame 22 decreases, thereby avoiding affecting the construction of the eaves structure and providing maximum protection.

[0031] In this embodiment, an anti-falling net 25 is disposed in the frame 22 to prevent personnel or equipment from accidentally falling to the ground.

[0032] In this embodiment, sliding limiters are provided at both ends of the sliding track 1 to prevent the construction platform 2 from falling off the sliding track 1 .

[0033] A connecting rope 4 may also be provided near the indoor side of the construction platform 2. After the construction platform 2 is moved to the construction area, it is connected to the indoor column through the connecting rope 4 to prevent it from accidentally tipping to the ground and causing loss of life and property.

[0034] Compared with the installation process of traditional scaffolding, the sliding installation construction of the utility model adopts the process of pre-welding finished steel frame on the ground and sliding installation, which has fast construction speed, easy to ensure construction safety, and can effectively reduce labor and save installation costs. It can also reduce the use of lifting machinery, reduce the use of fuel diesel and electricity, reduce noise nuisance and air pollution, and greatly reduce carbon emissions. The full-length rail steel can be reused after disassembly, which improves the utilization rate of materials.

[0035] The method of using the construction system in the utility model is as follows:

[0036] Measurement and setting out: Measurement and setting out should be coordinated with the measurement and setting out of the main structure. According to the control network and control points, the total station is used to accurately locate the control axis and elevation of the curtain wall. The horizontal elevation should be drawn from the intersection layer by layer to avoid error accumulation. The wind force should not be greater than level 3 during measurement to ensure accurate positioning and installation of components. Pop out the ink line along the outer edge of the structure or use steel wire to determine the plane position of the eaves keel.

[0037] Re-measurement of the installation accuracy of the cornice aluminum plate and establishment of a model to extract data: Use a total station to survey the actual coordinates and elevations of the characteristic points of the on-site steel structure roof and the column-free canopy steel truss, check the actual data and design errors, and feedback and adjust in time if the deviation exceeds the specification requirements to meet the installation requirements of the drawings. Establish a BIM model based on the measured data and extract the mobile platform data for platform construction. At the same time, the cornice aluminum plate is lowered according to the extracted relevant data to shorten the overall construction period.

[0038] Installation of sliding track and roller: Use total station for positioning, and first weld a section of sliding track 1 to the secondary purlin of the canopy. Then set up two rollers 21 on the sliding track 1, and use rollers 21 to transport the track steel for segmented installation, which can reduce the time for setting up the winch and shorten the construction schedule. To prevent the sliding track from running left or right and causing derailment, the two tracks should be parallel to each other with an error of less than 5mm.

[0039] Installation of mobile platform: The construction platform 2 is set up layer by layer based on the rollers 21 on both sides. First, the columns on both sides are positioned in sequence and temporarily fixed on the first-layer platform. After the column positions are positioned, they are leveled with a leveling instrument with a line on the same horizontal plane. After positioning, they are fully welded and fixed in time, and then the construction is carried out layer by layer. If there is any deviation, adjustments should be made.

[0040] Installation of cornice keel: cornice keel adopts hot-dip galvanized steel square tube. The finished steel frame is processed on the ground first, and then transported to the storage platform 3 for sliding installation. In order to reduce the friction and noise generated during sliding, a layer of lubricant is applied between the sliding guide rail 1 and the roller 21, which greatly reduces the high-altitude operation time and shortens the construction period.

[0041] Installation of surface aluminum plate: After the installation of the eaves frame is completed, the welding parts are polished and trimmed, and the keel welds are inspected and accepted. After passing the inspection, anti-rust paint is applied. The surface layer uses 3mm thick aluminum veneer, which is cleaned and glued after installation.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
