Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of curtain wall installation fixing device, and particularly relates to a curtain wall installation fixing device. BACKGROUND

[0002] In the field of modern building curtain wall construction, the choice of curtain wall installation method directly affects the construction efficiency, safety and engineering quality. The commonly used curtain wall installation methods in the industry mainly include traditional forms such as external scaffolding installation method, hanging basket installation method and internal installation combined with external hoisting method. However, these methods have obvious limitations: the external scaffolding installation method needs to build a large area of scaffolding outside the building, which not only consumes a large amount of materials and has a long construction period, but also is limited by the height and shape of the building. Especially for super high-rise buildings or special-shaped curved curtain walls, the stability and working space of the scaffolding are difficult to guarantee, and the risk coefficient of high-altitude operation is high. The hanging basket installation method does not need large-scale scaffolding construction, but the carrying capacity of the hanging basket is limited and can only meet the installation needs of small curtain wall panels. For heavy glass curtain walls, stone curtain walls and the like, the hanging basket may shake, resulting in installation precision deviation. At the same time, the movement and positioning operation of the hanging basket is complicated, which greatly reduces the construction efficiency.

[0003] In comparison, the external hoisting and internal installation method has obvious advantages due to its unique operation mode: considering the hoisting needs of the curtain wall panels, the existing curtain wall is usually provided with a temporary installation port (usually preset at the frame or stress structure of the curtain wall panel, used for connecting with the lifting tool of the hoisting equipment), and this method is to connect the lifting tool of the external hoisting equipment (such as a tower crane or a truck crane) with the temporary installation port of the curtain wall, and then stably hoist the curtain wall panel to the specified installation height, and the construction personnel perform the positioning, fixing and connecting operations of the curtain wall inside the building. This "external hoisting and internal operation" mode can completely avoid the safety hazards of the traditional external scaffolding or hanging basket operation outside the building, and the construction personnel do not need to be exposed to the high-altitude external environment, which effectively reduces the probability of safety accidents such as falling and object impact. On the other hand, the carrying capacity of the hoisting equipment is stronger, and combined with the convenient connection design of the temporary installation port of the curtain wall, it can meet the hoisting needs of large-size and heavy curtain wall panels, and the hoisting position adjustment is more flexible and is not limited by the shape and working space of the building, which greatly improves the construction efficiency, especially for complex engineering scenes such as super high-rise buildings and special-shaped curtain walls. In addition, the internal operation mode can also reduce the interference of the external environment (such as wind, rain and dust) on the construction process, ensuring the continuity and stability of the installation process and further guaranteeing the engineering quality.

[0004] However, the existing external hoisting and internal installation method still has the disadvantage that the position of the curtain wall cannot be well aligned and installed in actual application. Even if the curtain wall has a temporary installation opening to achieve convenient hoisting, it is still difficult to solve the core problem of subsequent positioning and alignment, which is embodied in the following aspects: First, the positioning reference of the curtain wall panel is difficult to accurately control. In the existing external hoisting and internal installation process, although hoisting is completed through the temporary installation opening, subsequent adjustment of the horizontal position, vertical height and in-out position of the curtain wall panel by the construction personnel through visual observation or simple measuring tools (such as a tape measure and a level) is still relied on. Due to the large size and heavy weight of the curtain wall panel, even if the lifting appliance is stably connected with the temporary installation opening, it is still easily affected by external factors such as wind force and lifting equipment operation error, resulting in slight shaking or deviation of the panel. When the construction personnel operate inside the building, they cannot intuitively observe the relative positional relationship between the curtain wall panel and the building main structure reference surface (such as a column or a beam), and it is difficult to accurately determine whether the panel has horizontal deviation, vertical inclination or in-out position deviation, thereby causing positioning error. Second, there is a lack of stable temporary fixing and fine adjustment mechanism. In the existing technology, after the curtain wall panel is hoisted into position through the temporary installation opening, it is usually only temporarily fixed by a simple support or a rope. This temporary fixing method has poor stability and cannot effectively limit the displacement of the panel in the horizontal and vertical directions.

[0005] In summary, although the existing external hoisting and internal installation method of the curtain wall optimizes the hoisting process by using the temporary installation opening of the curtain wall, and is superior to the traditional installation method in safety and efficiency, the problems of ambiguous positioning reference and unstable temporary fixing in the alignment and installation of the curtain wall position have become a key bottleneck restricting the installation quality and construction efficiency of the curtain wall, and it is urgent to develop a fixing device that can accurately realize the alignment and installation of the curtain wall position to solve the above technical defects.

[0019] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1-5 As shown, a curtain wall installation and fixing device of the present invention includes a mobile crane 1 placed on the roof and a rack trolley 2 placed inside the building. The mobile crane 1 moves on the roof to align with the curtain wall installation position and has a load to ensure that there is no tilting during the curtain wall hoisting process. The rack trolley 2 moves inside the building to align with the curtain wall installation position and has a load to ensure that there is no tilting during the curtain wall hoisting process. A connecting piece 3 is installed on the side of the rack trolley 2, and a straight plate 4 is hinged to the connecting piece 3. A moving wheel 5 is installed at the bottom of the straight plate 4, and a slide rail 6 is installed at the top of the straight plate 4. A moving seat 7 is slidably installed on the slide rail 6. The movable seat 7 is equipped with a displacement platform 8, the displacement platform 8 is slidably equipped with a moving strip 9, the moving strip 9 is equipped with a hinge 10, and the other side of the hinge 10 is equipped with a clamping block 11. The clamping block 11 is U-shaped and has a support plate 12 integrally formed. The clamping block 11 is equipped with toggle clamps 13 at both ends. The clamping block 11 has a through slot 14 at the pressing end of the toggle clamp 13. The toggle clamp 13 is equipped with an extension plate 14. The extension plate 14 is movably equipped with a capped screw 15. The capped screw 15 passes through the clamping block 11. The end of the capped screw 15 is fixedly connected to a pressure plate 16, which is located in the clamping position inside the clamping block 11.

[0021] In this implementation case, when using a curtain wall installation and fixing device, the mobile crane 1 is always above the installation area of ​​the curtain wall, and the rack trolley 2 can hold several curtain walls and serve as a curtain wall transfer trolley, while also serving as the load-bearing end of the straight plate 4. With the connection of connector 3 and the hinged installation of straight plate 4 and connector 3, by making straight plate 4 perpendicular to the moving surface of the shelf trolley 2, straight plate 4 can lean against the side of the shelf trolley 2 and move with the shelf trolley 2. Of course, because of the existence of connector 3, the shelf trolley 2 can be used as a general transfer tool by removing straight plate 4. When the shelf trolley 2 moves the curtain wall to the corresponding installation area, the relevant personnel will put the straight plate 4 flat, and the end of the straight plate 4 will protrude outside the floor to ensure cooperation with the mobile crane 1 and that it will not contact the floor beam when the curtain wall is subsequently stressed and inclined. The relevant personnel take the curtain wall from the shelf trolley 2 and insert the lower side of the curtain wall into the clamping block 11, so that the outer section of the lower side of the curtain wall is in contact with the inner bottom surface of the clamping block 11. Then the relevant personnel press the pressing plate 17 through the toggle clamp 13, so that the pressing plate 17 presses and clamps the curtain wall, that is, the position of the curtain wall in the clamping block 11 is fixed. The hoisting line, relevant hoisting tool or connecting tool of the working end of the mobile crane 1 is connected with the temporary installation port of the curtain wall, and the supporting plate 12 expands the contact area with the curtain wall to expand the support range of the curtain wall; The mobile crane 1 above is contacted to work, and the working end is started to retract. Under the effect of the force, the curtain wall and the clamping block 11 and the mobile seat 7 below the clamping block 11 which are fixed by clamping the curtain wall are moved. Under the effect of the slide rail 6, the movement of the mobile seat 7 will not have a large angle of position deviation, so as to reduce the adjustment range of the subsequent curtain wall alignment installation position. During the movement of the curtain wall, the curtain wall will slowly incline due to the self-gravity and the gravity pulling of the straight plate 4. When the curtain wall is completely moved to the installation position outside the floor, the curtain wall is basically in a completely vertical state. It should be noted that in order to ensure that the curtain wall can be moved and adjusted, the working end of the mobile crane 1 cannot be completely straightened. The curtain wall can be vertically erected on the displacement table 8 under the effect of the self-weight and the hinge 10; The relevant personnel start to fine-tune, directly manually pull the curtain wall or the moving strip 9 to move. The sliding matching of the moving strip 9 and the displacement table 8 enables it to move in the left-right direction, and the cooperation of the mobile seat 7 and the slide rail 6 enables it to move in the front-back direction. The movement in two directions ensures the adjustment effect, and the support of the curtain wall enables the relevant personnel to not need to use too much force. When the relevant personnel move the curtain wall to the pre-installation position, the curtain wall is pre-installed, and then the toggle clamp 13 is released. The moving strip 9 is directly moved horizontally, or the entire shelf trolley 2 is moved. Under the movable support of the moving wheel 5, the entire clamping block 11 can completely separate from the curtain wall, and the next curtain wall is prepared for placement, connection, installation and fixation; As a further implementation scheme, by using two devices, the sides of the clamping blocks 11 on the two devices can be opposite, that is, when the sides of the two clamping blocks 11 are aligned and in contact, the sides of the curtain walls of the same specification fixed thereon are also aligned. This method can realize the simultaneous pre-installation of two curtain walls and ensure the flatness of the installation connection of the two curtain walls. As a further utilization, a curtain wall can be connected to another curtain wall which has been fixed and installed in this way, so as to ensure the overall flatness quality after the installation of the curtain wall is completed.

Subsequently, the slide rails 6 are rigidly connected with the straight plate 4 by using bolt fastening or welding, so as to avoid displacement or inclination between the slide rails 6 and the straight plate 4 during use. Further, the slide rails 6 and the straight plate 4 can be integrally formed. Compared with a single slide rail or two slide rails, the three slide rails 6 that are parallel to each other and installed on the straight plate 4 greatly expand the sliding support force on the sliding component, can uniformly disperse the weight and load of the sliding component to the three slide rails 6 and the straight plate 4, avoid local wear or deformation of a single slide rail due to force concentration, and thus significantly strengthen the stability of the sliding process. During sliding, the sliding component will not deviate left and right, shake or jam due to insufficient support points, and always relies on the slide rails on the straight plate 4 to move smoothly along the preset track. At the same time, the dispersed force can effectively reduce the unit area load of each slide rail 6, reduce the friction loss of the slide rail 6, avoid the decrease or damage of the slide rail precision caused by local excessive wear, and further improve the installation stability of the slide rail 6 by the rigid foundation of the straight plate 4, thereby prolonging the service life of the slide rail 6 and the entire sliding system.

Subsequently, the slide rails 6 are rigidly connected with the straight plate 4 by using bolt fastening or welding, so as to avoid displacement or inclination between the slide rails 6 and the straight plate 4 during use. Further, the slide rails 6 and the straight plate 4 can be integrally formed. Compared with a single slide rail or two slide rails, the three slide rails 6 that are parallel to each other and installed on the straight plate 4 greatly expand the sliding support force on the sliding component, can uniformly disperse the weight and load of the sliding component to the three slide rails 6 and the straight plate 4, avoid local wear or deformation of a single slide rail due to force concentration, and thus significantly strengthen the stability of the sliding process. During sliding, the sliding component will not deviate left and right, shake or jam due to insufficient support points, and always relies on the slide rails on the straight plate 4 to move smoothly along the preset track. At the same time, the dispersed force can effectively reduce the unit area load of each slide rail 6, reduce the friction loss of the slide rail 6, avoid the decrease or damage of the slide rail precision caused by local excessive wear, and further improve the installation stability of the slide rail 6 by the rigid foundation of the straight plate 4, thereby prolonging the service life of the slide rail 6 and the entire sliding system.
