Description

Technical Field

[0001] The invention relates to the technical field of curtain wall construction, and in particular to a construction method of a refined steel inclined curtain wall. Background Art

[0002] With the diversified development of modern architectural design concepts, architects are constantly breaking through the constraints of traditional architectural frameworks with extraordinary creativity, integrating complex roof shapes such as sloped and curved shapes into architectural design, adding infinite vitality and charm to the city skyline. The sloped curtain wall construction structure is favored in construction projects for its unique aesthetic effect and good lighting performance. However, its construction difficulty is also increased accordingly, especially in controlling the inclination angle of the finished surface of the glass curtain wall, the installation of the frame, and the accuracy of the panel joints.

[0003] The existing inclined glass curtain wall faces a series of technical difficulties in the actual construction process, which are mainly reflected in the following aspects: 1. It is difficult to accurately control the tilt angle of the finished surface of the glass curtain wall. Due to the tilt characteristics of the inclined curtain wall, a slight angle deviation may have a significant impact on the appearance and stability of the entire curtain wall. However, existing technical means cannot perform adaptive tilt adjustment.

[0004] 2. Difficulty in frame installation. The frame system of the inclined curtain wall needs to withstand greater wind pressure and deadweight, while also maintaining a stable tilt angle. This makes the installation of the frame extremely complicated, requiring high-precision measurement and positioning, as well as professional installation technology.

[0005] 3. The accuracy of panel joints is also difficult to guarantee. The panel joints of the inclined curtain wall need to be tightly fitted to prevent rainwater leakage and air infiltration. At the same time, due to the existence of the tilt angle, the splicing between panels becomes very difficult, and it is difficult to achieve a perfect joint effect.

[0006] 4. The existing adapters have a single structure and cannot meet the requirements of curtain wall construction with different tilt angles. As a key component connecting the keel and the main structure, the length and shape of the adapter need to be customized according to different construction nodes. However, most of the existing adapters use a U-shaped card holder structure and are adjusted through flat holes. This structure is too simple in the construction of tilted curtain walls and cannot meet the requirements for precise adjustment of the tilt angle.

[0007] Based on this, it is necessary to study a construction method for refined steel slope curtain wall. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a refined steel slope curtain wall construction method, which is mainly used for the construction of inclined curtain walls. For the inclined curtain wall construction method, the adapter is the core component connecting the building body and the keel unit, and is also the inclined support base of the keel unit. The current adapter has a simple structure and cannot be adaptively adjusted in angle, resulting in the adapter needing to be customized according to the structural characteristics of the building body, making angle adjustment difficult and construction troublesome. Based on this, this embodiment provides a refined steel slope curtain wall construction method.

[0024] like Figure 1 As shown in, a refined steel slope curtain wall construction method comprises the following steps: Step 1: Survey and measurement The inclined construction surface is measured to obtain on-site data, and the on-site data is reviewed in combination with the construction drawings to resolve the engineering deviation data, check the axis elevation, and complete the construction markings on site; this implementation example Figure 2 As shown in , the structural body has a multi-story structure, and the inclined curtain wall is arranged on the outer side of the multi-story structure.

[0025] Step 2: Construction layout According to the construction markings, standardized signs are sprayed on site. The standardized signs include axis lines, finished surfaces, embedded plate marks and keel marks. Specifically, the elevation lines and axis lines of each floor are used as reference lines, and auxiliary axis lines are measured from the original axis control points and elevation points, and auxiliary marks are made on the corresponding levels.

[0029] Axis and elevation verification: After entering the construction site, the construction personnel will verify the axis position, original elevation point and one-meter elevation line or 50 line provided by the general contractor. Appropriate and reasonable allocation of the errors that occur, and after inspection and confirmation, fill in the axis and original elevation point actual measurement record table.

[0030] 2. “Guide” is mainly divided into floor elevation line, axis line and control line.

[0031] Draw floor elevation lines: Pull a ruler upward to measure and set the line to the main floor based on the verified original elevation point, mark the relative elevation of each floor on the column or wall of each floor, and draw points to other facades and mark them based on the elevation point of each floor.

[0032] Lead the axis line and control line: Lead the verified axis line and control line to the four corners and the positive and negative corners of each floor's building structure.

[0033] 3. “Measurement” is mainly divided into measuring the deviation of the main structure and the relationship between the axis, control line and the entry and exit of the curtain wall.
