Technical Field

[0001] The invention belongs to the technical field of curtain wall frame assemblies, and in particular relates to a strip glass curtain wall half-unit frame assembly structure and an installation method thereof. Background Art

[0002] Curtain wall forms are divided into component-type curtain wall and unit-type curtain wall according to the assembly process of the supporting frame. The component-type curtain wall is a frame-supported building curtain wall in which columns, beams and panels are installed in sequence on site. The unit-type curtain wall is a frame-supported building curtain wall composed of panels and supporting frames processed in the factory. The basic unit height of the curtain wall structure is not less than the floor height, and it is directly installed on the main structure to form a frame-supported building curtain wall.

[0003] The existing component-type curtain wall has a simple structure, low cost and low installation precision. With the increase in labor costs, the component curtain wall has high on-site installation costs due to the many on-site installation processes, and cannot meet the construction requirements under long rainy seasons and complex weather conditions. In addition, the component-type curtain wall requires operators to work at heights for a long time and many times, which poses great safety hazards and causes noise and pollution during installation and construction.

[0004] The existing unitized curtain walls use more materials to assemble the units in the processing plant than the component curtain walls, so the overall consumables and construction costs are higher than the component curtain walls. In addition, the stability of the connection between the existing unit assembly frames and the glass panels is insufficient. The safety performance of the glass curtain walls is poor under complex weather conditions, and the curtain walls are easily damaged or seeped due to strong winds or heavy rains.

[0016] A method for installing a half-unit assembly frame of a linear glass curtain wall is applied to the above-mentioned half-unit assembly frame assembly structure of a linear glass curtain wall, comprising the following steps: S1. Curtain wall model components: Modeling is completed and saved through BIM technology, the model surface is divided into grids, and relevant data information is obtained.

[0017] S2. On-site structural re-measurement: Use total station, level, plumb line and other equipment to lay out and measure the outer contours of the beam surface of this layer and the bottom of the upper beam, record the measurement data and return it to the designer for re-modeling, and output the model data after the adjustment is qualified.

[0018] S3. Model data output: Designers propose material data based on the BIM model and perform real-time optimization as needed.

[0019] S4. Profile processing: According to the BIM model data, the profile processing processes such as hole positioning, drilling, and cutting are transferred to the on-site indoor processing. The aluminum profile cutting platform is equipped with a steel tape measure. The cutting size is calculated and the profile is accurately fixed. Air pressure cutting is used to achieve one-time positioning and multiple cutting. The positioning and cutting are integrated. The two sides of the aluminum profile punching platform are adjusted and fixed according to the length of the profile. Multiple drilling machines work at the same time to achieve integrated positioning and drilling, and complete the precise processing of various aluminum profiles. Through the optimized adjustment of the cutting and drilling control platform processing, It greatly improves the accuracy and reduces the height operation. The main processed components are beams and columns. The column specifications are processed according to the project needs, such as 155mm columns and 120mm columns, etc. The beam length specifications can be adjusted according to the specific floor requirements. It should be noted during processing that the allowable error of the processed part length is 0.2mm, the allowable error of the beam pin hole and the remaining holes is 0.3mm, and the allowable angle error is 5 degrees. After the material is processed, the burrs must be removed, and the corresponding number labels must be filled in, and the exposed surface must be filled with film to prevent scratches.

[0020] S5, semi-unit frame assembly: After material procurement and on-site CNC equipment processing are completed and numbered, frame assembly is carried out according to the requirements of the beam and column direction in the figure, and the installation of aluminum alloy column rubber strips and inserts and beam rubber strips is completed at the same time. Before mass frame assembly, a trial assembly should be carried out. The finished products need to be uniformly classified according to specifications, uniformly placed in the pre-set finished product stacking area, and transported to the construction site as needed to avoid material waste and damage.

[0021] S6. On-site layout and installation of embedded parts: After measurement by total station, level and other measuring equipment and the designer's verification of the data replication, positioning marking is carried out and embedded parts are installed on the beam surface of this layer. M12 post-cut and mechanical anchor bolts are used in conjunction with 10mm thick steel plate embedded parts.

[0022] S7. Installation of semi-unit curtain wall frame: When transferring and installing semi-unit, use equipment such as level and plumb line to calibrate and adjust to the accurate model parameter position. The matching flat washers, spring washers and steel washers are installed according to the drawings and specifications. The lower end of the unit frame is connected to the embedded parts through the insert, one side is fully welded, and the upper end is connected to the embedded parts through two 100*63*6 angle steels. The angle steels are connected to the columns through stainless steel bolt groups.

[0023] The technical effects achieved by the present invention are: The present invention adopts the structural feature of setting a supporting mechanism, wherein two side frames are fixedly provided on the outer side of the column, and then a fixing plate and a shock-absorbing rubber strip arranged on the outer side of the fixing plate are fixedly provided on the inner side of the side frame, and the inner side of the side frame is an open cavity, and then the fixing plate is installed in the cavity, and at the same time, a dovetail tenon is integrally formed at one end of the side frame, and then a dovetail groove is opened on the side of the fixing plate close to the column, so that the side frame and the fixing plate are fixedly connected by mortise and tenon connection, thereby enhancing the stability of the connection between the side frame and the fixing plate and improving the detachability of the overall structure, and a shock-absorbing area is formed by the dovetail groove to prevent the assembly frame from shaking due to strong wind, thereby causing the side frame to loosen, thereby enhancing the stability of the glass plate.

[0024] The present invention simplifies the one-time horizontal measurement and the assembly process of columns and beams on the high working surface by using a semi-unit framing installation process, and adjusts the installation process of columns and beams to the factory and indoor processing site to complete the assembly uniformly. After the engineer uniformly processes through the CNC processing platform, the workers can assemble the frames indoors to form assembled keel units, forming standardized and modular products. After simplifying the installation process, the curtain wall supporting components are installed on the wall at one time, which improves the assembly rate, reduces the interference with the surrounding environment, is conducive to safe and civilized construction, reduces the time and number of workers' high-altitude operations, reduces safety risks, improves the quality of finished products and the accuracy of curtain wall installation, reduces construction safety hazards, and can cope with construction under complex weather conditions and solve problems such as short effective construction period.

[0025] The present invention uses the characteristics of the semi-unit frame structure to facilitate operation, reduce labor consumption, shorten construction period, and reduce costs.

The aluminum profile cutting platform is equipped with a steel tape measure. The cutting size is calculated to accurately fix the profile. Pneumatic cutting is used to achieve one-time positioning, multiple cutting, and integrated positioning and cutting. The two sides of the aluminum profile punching platform are adjusted and fixed according to the length of the profile. Multiple drilling machines work at the same time to achieve integrated positioning and drilling, and complete the precise processing of various aluminum profiles. The processing of the cutting and drilling control platform is optimized to greatly improve the accuracy and reduce high-altitude operations.
