Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a fixing frame for building exterior wall construction. Background Art

[0002] The fixed frame for building exterior wall construction provides a safe, stable and easy-to-operate working platform for construction workers during the construction process, enabling them to carry out wall decoration, installation of external insulation materials, and painting on the exterior walls of the building. It is built with metal pipes and other solid materials, has a certain strength and load-bearing capacity, and can withstand the weight of construction workers, construction tools and some building materials. The fixed frame is connected to the exterior wall of the building through a specific connection method to ensure that there will be no shaking or displacement during the construction process, providing guarantee for the smooth progress of construction.

[0003] With the continuous development of the construction industry and the acceleration of urbanization, high-rise buildings are increasing, and the difficulty and complexity of building exterior wall construction are also increasing. The importance of fixed frames is becoming more and more prominent. In modern building construction, fixed frames are not only required to meet basic safety and functional requirements, but also need to adapt to the requirements of different building structures and construction processes. For buildings with unique shapes, fixed frames need to have better flexibility and adaptability to ensure that they can be built and used on various complex exterior wall surfaces. As people's requirements for construction efficiency and quality continue to increase, the design of fixed frames is also constantly improving and innovating to improve the convenience and efficiency of construction.

[0004] A search revealed Chinese patent publication number CN2495742Y, which discloses an exterior wall construction scaffold. The scaffold has sleeves on either side that fit over the two uprights, allowing the scaffold to slide up and down along the uprights. The uprights are connected to the wall connectors via pipe clips. This utility model combines the advantages of a hanger and a single-row exterior wall scaffold. The scaffold can be flexibly raised and lowered along the uprights by a lifting device, ensuring smooth, swing-free construction, strong wind resistance, and excellent stability. However, this structure fails to address the complex structure, inconvenient assembly and disassembly, poor stability, insufficient safety, and high cost, making it difficult to meet operational requirements. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a fixing frame for building exterior wall construction, aiming to improve the problems of the prior art such as complex structure, inconvenient assembly and disassembly, poor stability, insufficient safety and high cost.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fixed frame for the construction of the exterior wall of a building, comprising a column, the outer wall of the column is fixedly connected to a fixed sleeve, the outer wall of the right side of the fixed sleeve is fixedly connected to a plate frame on the left side, the inner wall of the plate frame is slidably connected to multiple top plate columns, the bottom of the top plate column is fixedly connected to a clamping strip, the rear side of the outer wall of the fixed sleeve is rotatably connected to a connecting rod, the other end of the connecting rod is rotatably connected to a square block, the rear side of the square block is rotatably connected to a pedal, the bottom end of the column is fixedly connected to a sliding sleeve, the inner wall of the sliding sleeve is slidably connected to a sliding column, and a safety mechanism is provided on the top of the column, which is used to protect the safety of personnel at work.

[0007] Through the above technical solution: in the structure of the column, a fixed sleeve is fixedly connected to the outer wall of the column for fixing and installing other structures. The left side of the outer wall of the fixed sleeve is connected to a plate frame, and a plurality of top plate columns are evenly slidably connected on the inner wall of the plate frame. The bottom of each top plate column is fixedly connected to a clip to ensure its stability. The rear side of the outer wall of the fixed sleeve is connected to a connecting rod by rotation, and the other end of the connecting rod is connected to a square block by rotation. The rear side of the square block is connected to a pedal by rotation, making the entire structure more flexible and practical. A sliding sleeve is also fixedly connected at the bottom end of the column. The inner wall of the sliding sleeve can be slidably connected to a sliding column to meet the needs of use. A safety mechanism is set at the top of the column. The main function of this safety mechanism is to protect the safety of staff during various operations and ensure that they can be fully protected when using equipment.

[0008] As a further description of the above technical solution:

[0009] The safety mechanism includes a column slot, which is opened on the inner wall of the column. The inner wall of the column slot is slidably connected to a protective column. The top of the protective column is rotatably connected to a protective long fence. A fence slot is opened on the front side of the protective long fence. The left and right sides of the inner wall of the protective long fence are rotatably connected to multiple protective wide fences. A fixing bolt is installed on the top of the outer wall of the protective column.

[0010] Through the above technical solution: the design of the safety mechanism provides a reliable protection mechanism to ensure the safety and stability of the column, and the column grooves are cleverly opened on the inner wall of the column.

The inner wall of the column groove is slidably connected to the protective column, and the protective column can be installed in the column groove as needed to meet different protection needs. The top of the protective column is connected to the protective long bar by a rotating connection. This connection method enables the protective long bar to rotate freely within a certain range, thereby providing more flexible protection. The front side of the protective long bar is provided with bar grooves, which can be used to store other components to enhance the overall safety performance. In order to further improve the protection effect, multiple protective wide bars are rotatably connected on both sides of the inner wall of the protective long bar. These protective wide bars can rotate freely in the horizontal direction, which is convenient for installation and storage. Fixing bolts are also installed on the top of the outer wall of the protective column. These fixing bolts are used to fix the entire safety mechanism in the appropriate position to ensure its stability and reliability during use.

[0018] The right side of the top of the pedal is fixedly connected with an anti-skid pad 1, and the left side of the top of the pedal is fixedly connected with an anti-skid pad 2.

[0019] Through the above technical solution: an anti-slip pad 1 is carefully fixed and connected to the top right part of the pedal. This anti-slip pad 1 functionally provides additional grip, and an anti-slip pad 2 is also cleverly fixed and connected to the top left part of the pedal. This anti-slip pad 2 complements the anti-slip pad 1 in structure, jointly ensuring the safety and comfort of the user when using the pedal.

[0020] As a further description of the above technical solution:

The protective long bar 203 is rotatably connected to the protective wide bar 205, and a bar groove 204 is opened on the inner wall of the protective long bar 203 to facilitate the folding of the protective wide bar 205. When in use, the protective wide bar 205 is unfolded and the hole is aligned with the protective column 202. After both bars are installed, the fixing bolt 206 is inserted into the groove of the protective column 202 to complete the fixation. Such a structure improves safety, is quicker to install, has a stable structure, and is of low cost, thus meeting safety requirements.
