DETAILED DESCRIPTION

[0024] 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 an assembled construction method of an inverted frustum fireproof glass curtain wall, which is mainly used to form the main body of an inverted frustum fireproof glass curtain wall. The current construction method cannot be applied to the inverted frustum fireproof glass curtain wall structure, which makes the construction of the inverted frustum fireproof glass curtain wall difficult and the construction period long. The stability, sealing and fire resistance between the structures cannot meet the requirements. Therefore, this embodiment provides an assembled construction method of an inverted frustum fireproof glass curtain wall.

[0025] Specific as Figure 1-2 As shown in , an assembled construction method of an inverted frustum fireproof glass curtain wall comprises the following steps: Step 1: Construction layout Take the elevation line and axis of each floor as the reference line, measure the auxiliary axis from the original axis control point and elevation point, and make auxiliary marks on the corresponding level; determine the position of horizontal post-embedded parts according to the construction drawings and the horizontal elevation line on site, and make embedded plate marks; determine the position of vertical and horizontal keels according to the curtain wall grid diagram, and make keel marks.

[0026] When positioning and laying out, the four-byte method of exterior curtain wall construction is used for laying out, including: "check", "guide", "measure", and "determine".

[0027] 1. “Check” mainly includes the calibration of instruments before construction and the review of the axis and elevation provided by the general contractor.

[0028] Calibration of instruments: Before entering the construction site to lay out the lines, construction personnel will calibrate instruments such as levels and theodolites to ensure the accuracy of the measurements.

[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.

[0034] ① Measure the main structure: measure the deviation of the main structure axis and elevation line and make timely adjustments.

[0035] ② Measure the relationship between the axis line, control line and the entry and exit of the curtain wall: After measuring the axis line and floor height, determine its entry and exit relationship with the finished surface of the curtain wall according to the construction drawings.

[0036] 4. "Positioning" is mainly divided into post-embedded parts positioning and keel positioning.

[0037] ① Determine the position of post-embedded parts: Determine the position of horizontal post-embedded parts according to the construction drawings and the horizontal elevation line on site.

[0038] ② Determine the position of the keel: According to the curtain wall grid diagram, the axis position at the corner can be divided and positioned between the two corner points. First determine the vertical keel, then the horizontal keel. Each vertical keel and horizontal keel of each facade must be marked and marked.

[0039] Step 2: Determination of curtain wall dividing line and keel line Determine the corner position and construct the corner vertical line. Then divide the grid between the two corner points according to the grid size, connect the upper and lower lines to form an overall control network. According to the distance between the surface line of the drawing and the keel line, the keel line is reversed inwards as the basis for installing the keel. Step 3: Post-embedded plate and adapter construction At the buried plate mark, the rear buried plate is constructed and the adapter is fixed on the rear buried plate; the end of the adapter is provided with a long hole; the rear buried plate includes a side buried plate, a top buried template and a bottom buried template. When installing the buried plate, the main steps include measuring and laying out → positioning and drilling → hole cleaning → screw installation → rear buried part fixing → nut tightening.

The upper concrete structure beam bears the main force of the glass curtain wall, and the lower part will bear the lateral force of the glass curtain wall. The plug of steel column 1 is welded and fixed to the three sides of the rear embedded parts. According to the axis and elevation of the main beam, the elevation deviation of column 1 is adjusted to no more than 3mm, the front and rear deviation of the axis is adjusted to no more than 2mm, and the left and right deviation is adjusted to no more than 3mm; noise-proof and fire-proof rubber gaskets are fixed between column 1 and channel steel to reduce the noise generated when the curtain wall moves and prevent damage caused by rigid connections.

The steel insert is set on the inner side of the upper column 1 and fixed by bolts; a sleeve is set on the inner side of the lower column 1, and the insert is set in the sleeve and fixed on the rear embedded plate. When implementing, first check whether the size of the main beam and the processing hole position are correct according to the construction drawing, and then install the column 1 insert on the inner side of the steel column 1. The column 1 and the steel insert are fixed with M12 stainless steel bolts, the verticality and horizontality of the column 1 are adjusted, and then the insert is welded and fixed to the embedded plate to make the final fixed position.

[0044] The curtain wall columns 1 are connected with each other through inserts, and expansion joints are reserved. All hard contacts are connected with elasticity to improve the anti-seismic performance of the curtain wall and eliminate expansion noise. It is ensured that under the action of temperature, settlement and other external forces, it can expand and contract relatively, absorb deformation, and ensure that the column 1 is not damaged.

A notch is opened in the front section of the connecting seat to facilitate the fixation of the beam. Then the inserts and the beam are fixed, and the steel inserts are used to extend and retract with column 1.

[0046] Step 5: Interlayer fire protection installation A fireproof structure is constructed between the curtain wall keel and the interlayer floor 8. The fireproof structure is supported by fireproof rock wool and an external galvanized steel plate, and is sealed after construction. The fireproof structure includes an interlayer fireproof structure 9 and a transverse fireproof structure 10. The interlayer fireproof structure is arranged between the interlayer floor and the curtain wall body and fixed on the adapter 6.

[0050] 2. Improved the sealing and fireproofing of the curtain wall: During the interlayer fireproofing installation and glass panel installation, this method uses fireproof rock wool, galvanized steel plate support, fireproof rubber pads and other fireproof materials, and adds sealant to effectively improve the sealing and fireproofing of the curtain wall. This design not only meets the building safety requirements, but also improves the thermal insulation and sound insulation of the curtain wall.

[0051] , Optimized the curtain wall construction process: This method divides curtain wall construction into multiple clear and orderly steps, each of which has clear tasks and operation requirements.
