Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a spacer block and an assembly method for on-site assembly of U-shaped glass. Background Art

[0002] In modern architectural design, U-shaped glass is widely used in building structures such as curtain walls and partitions due to its unique aesthetics and light transmittance. However, the installation of ultra-long U-shaped glass has always faced many technical problems. Traditional installation methods usually have problems such as low installation accuracy, poor construction efficiency, and insufficient stability.

[0003] For example, the invention with the publication number CN117090330A and the invention name "Longitudinal Installation Structure and Method of U-shaped Glass Curtain Wall" discloses a longitudinal installation structure and method of a U-shaped glass curtain wall. At the bottom, a basic U-shaped steel plate is used as the support and positioning member at the bottom of the curtain wall, and a bottom U-shaped aluminum frame is used to fix the U-shaped glass; at the interlayer position, an interlayer steel plate is used as the partition and support member at the interlayer of the curtain wall, and an H-shaped aluminum frame is used to fix the U-shaped glass of the upper and lower layers; at the positions of door and window openings, a hole-opening keel is used for closing the opening, and a hole-opening U-shaped aluminum frame is used to fix the U-shaped glass; at the parapet wall at the top, a top steel plate is used for finishing and pressing the top, and a top U-shaped aluminum frame is used to fix the U-shaped glass. The connection node of the present invention has a simple and stable structure, low processing difficulty, each layer of U-shaped glass can be independently installed, and both longitudinal ends of the U-shaped glass have support and limit, with strong local anti-deformation ability, and can be applied to multi-story or mid-rise buildings.

[0004] However, when facing the assembly of ultra-long U-shaped glass, it is necessary to connect multiple ultra-long U-shaped glasses to form an integral glass wall, which involves the installation problems of multiple ultra-long U-shaped glasses. The existing curtain wall construction methods have problems such as complex construction steps, long construction period, and difficult-to-guarantee construction quality. There is an urgent need for a new construction method to solve these problems. Summary of the Invention

[0005] Aiming at the above problems existing in the prior art, the purpose of the present invention is to provide a U-shaped glass installation method that can effectively shorten the construction and installation period and improve the installation quality.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0007] The present invention provides an ultra-long U-shaped glass installation method, including the steps of:

[0008] Step 1, construction preparation;

[0009] Step 2, installation pretreatment;

[0010] Step 3, installation of keel and connecting pieces;

[0011] Step 4: Construction and installation of double-layer extra-long U-shaped glass;

[0022] (22) Fixing the embedded parts based on the positioning of the measurement and layout, specifically welding the embedded parts to the set position and installing an adjustable positioning bracket;

[0023] (23) Review position deviation.

[0024] In some embodiments, the position deviation verification in step (23) is specifically as follows: the position deviation of the station re-measurement is ≤5mm in plane position and ≤3mm in elevation; the difference is compensated by using gaskets or welded extension plates.

[0025] In some embodiments, the installation of the keel and the connector in step 3 is specifically as follows:

[0026] (31) Install the upper keel and lower keel at the installation point respectively;

[0027] (32) Confirm that the upper keel, lower keel and embedded parts are fixedly connected

[0028] (33) Re-measure the installation to confirm it.

[0029] In some embodiments, it further includes step of factory processing. After completing the re-measurement and confirmation process, the U-shaped glass is processed based on the re-measurement data, specifically including filling glass fiber inside the U-shaped glass that needs to be spliced.

[0030] In some embodiments, it further includes surface cleaning, which is to clean the surface of the installed U-shaped glass.

[0031] In some embodiments, the installation of the U-shaped glass in step (43) specifically includes:

[0032] (431) Bottom positioning: Before inserting the lower end of the glass into the bottom notch, first pad a 5-mm-thick EPDM rubber pad; the reserved expansion joint width of the bottom notch = 0.1% of the glass length.

[0033] (432) Lateral fixation: Use a stainless-steel pressing plate to clamp the glass into the frame, and add a 2-mm-thick nylon gasket between the pressing plate and the glass; the tightening sequence of the bolts: tighten alternately from the middle to both ends.

[0034] (433) Top limit: The U-shaped glass is "floatably" fixed in the top notch, allowing the glass to expand and contract within the range of ±5 mm.

[0035] In some embodiments, the frame is a composite frame, with the outer layer made of aluminum alloy and the inner layer made of a PVC heat-insulating layer.

[0036] In some embodiments, it further includes sealing treatment. After the installation of the U-shaped glass is completed, silicone weatherproof glue is injected between the glass and the frame, and the width of the glue joint is 9 - 12 mm.

[0037] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0038] 1. Through precision prepositioning, precise measurement preparation in the construction preparation and installation pretreatment steps, the present invention realizes precise positioning, ensures fixing rigidity, and eliminates systematic errors as much as possible, so as to effectively improve the installation efficiency of subsequent operations.

[0046] Step 1. Construction preparation;

[0047] Step 2. Installation pretreatment;

[0048] Step 3. Installation of keel and connectors;

[0049] Step 4. Construction and installation of double-layer extra-long U-shaped glass;

[0050] Among them, the installation of the double-layer extra-long U-shaped glass is specifically as follows:

[0051] (41) Hoist it to the installation point by a truck crane;

[0052] (42) Fill the double-layer U-shaped glass with glass fiber and assemble it;

[0053] (43) Hang the double-layer U-shaped glass to the installation point for installation;

[0054] (44) Make a fireproof rock wool layer sealing for the installed U-shaped glass.

[0055] In some embodiments, the construction preparation described in Step 1 specifically includes the steps:

[0056] (11) Obtain and review the design drawings, construction specifications and standards of the on-site U-shaped glass to be installed; in some complex construction sites, the construction preparation also includes confirming that there are no obstacles in the transportation passage, and avoiding dangerous areas such as high-voltage lines in the hoisting path, etc.;

[0057] (12) Set up a scaffolding and complete the measurement and layout, and the measurement and layout specifically include: establishment of reference lines, positioning of dividing lines, and positioning of support structures;

[0058] In some embodiments, in order to further improve the safety of the installation process, the extra-long U-shaped glass can be "test hoisted" to verify the center of gravity position and the stability of the hoisting equipment, and prevent imbalance during formal installation.

[0059] In some embodiments, the installation pretreatment described in Step 2 specifically includes the steps:

[0060] (21) Confirm the model, position and force requirements of the embedded parts according to the design drawings, and determine the compatibility of the embedded parts with the U-shaped glass support frame;

[0069] In some embodiments, the method further includes surface cleaning, in which the surface of the U-shaped glass is cleaned after installation.

[0070] In some embodiments, the U-shaped glass installation in step (43) specifically includes:

[0071] (431) Bottom positioning: Before inserting the lower end of the glass into the bottom notch, first insert a 5mm thick EPDM rubber pad; the width of the expansion joint reserved in the bottom notch = glass length × 0.1%;

[0072] (432) Horizontal fixation: Use a stainless steel pressure plate to clamp the glass into the frame, and add a 2mm thick nylon gasket between the pressure plate and the glass; Bolt tightening sequence: Tighten alternately from the middle to both ends;

[0073] (433) Top limit: The top notch "floatably" fixes the U-shaped glass, allowing the glass to expand and contract within a range of ±5 mm.

[0075] In some embodiments, a sealing treatment is further included. After the U-shaped glass is installed, silicone weatherproof glue is injected between the glass and the frame, and the width of the glue joint is 9 - 12 mm.

[0076] Finally, it is necessary to point out here that: The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
