Description

Technical Field

[0001] The present invention relates to the field of glass deep processing, and particularly to a method for splicing glass bricks and the spliced glass thereof. Background Art

[0002] A glass curtain wall is generally composed of laminated flat glass, with an increased thickness and enhanced load-bearing capacity. At the same time, due to the laminated composite glass being treated under high temperature and high pressure, the glass is bonded to the SGP film, making the glass curtain wall safer. However, the flat glass curtain wall lacks artistic sense due to its overly flat surface. Glass brick walls, with their high crystal-like appearance, showcase the unique aesthetics and practicality of glass bricks in architectural design and are welcomed by more and more architects and clients. Existing glass brick walls are built by stacking glass bricks one by one, giving them a sense of hierarchy. Moreover, the surface area of the glass bricks is small, and there can be more three-dimensional structures such as concavities and convexities on their surfaces, or splicing patterns can be designed to make the glass brick walls more artistic. However, the bonding between glass bricks is made of opaque materials, making the glass brick walls appear not completely transparent, showing a blocked effect, which greatly affects the aesthetics of the glass brick walls. Summary of the Invention

[0003] In response to the needs in the above field, the present invention provides a method for splicing glass bricks, and the prepared spliced glass not only has the sense of hierarchy spliced by glass bricks, but also the whole glass is completely transparent without the appearance of a blocked phenomenon.

[0004] The method for splicing glass bricks includes the following steps:

[0005] (1) Provide a flat single-layer glass or structural glass as a substrate.

[0006] (2) Lay the substrate flat and lay a large whole SGP film on its upper surface. The size of the large SGP film is the same as or slightly smaller than the size of the flat glass or structural glass.

[0007] (3) Starting from a corner of the substrate, stack glass bricks on the large SGP film, with small SGP films sandwiched between adjacent glass bricks, and cover the entire large SGP film with glass bricks; the size of the small SGP film is the same as or slightly smaller than the contact surface size between adjacent glass bricks.

[0008] (4) Wrap the substrate and the laid glass bricks together with a vacuum bag, after vacuum treatment, enter the autoclave in a horizontal feeding manner, and then perform high temperature and high pressure treatment, or

[0009] Wrap the substrate and the laid glass bricks together with a vacuum bag, perform vacuum treatment, and enter the autoclave in a horizontal feeding manner, then carry out high-temperature treatment or high-temperature and high-pressure treatment. After taking out of the autoclave, turn it over, repeat steps (2) and (3) to stack glass bricks on the other side of the substrate, then wrap the substrate and the laid glass bricks together with a vacuum bag again, after vacuum treatment, enter the autoclave in a horizontal feeding manner, and then carry out high-temperature and high-pressure treatment.

[0010] The substrate is double-layer laminated glass.

[0011] The thickness of the large SGP film is 1.52 mm, and the thickness of the small SGP film is 2.28 mm.

[0012] The high-temperature treatment is to set the temperature at 110 degrees.

[0013] The high-temperature and high-pressure treatment is to set the temperature at 135 degrees and the pressure at 1.25 MPa.

[0014] The glass bricks on both sides of the substrate are equal in size, equal in number, and corresponding in position.

[0015] The length of the glass brick is the same as or slightly shorter than the length of the substrate, and the glass bricks are stacked in a row on the large SGP film.

[0016] Before stacking the glass bricks, draw the position lines of the glass bricks on the end face of the substrate, and stack the glass bricks neatly according to the position lines.

[0017] The glass brick splicing glass obtained by the above method.

[0018] A glass brick wall is spliced and formed by the glass brick splicing glass described above.

[0019] In the conventional stacking of glass brick walls, generally, the method of directly stacking from bottom to top on-site is adopted. However, the splicing glass in this application is prepared in the factory and then fixedly installed on-site after the glass bricks are spliced. This application is related to the preparation method of this glass brick splicing glass. This application uses a flat glass as the substrate, stacks and fixes glass bricks on one side or both sides of the substrate, and uses SGP film for bonding between the glasses, thus forming glass brick splicing glass. Moreover, this application is different from the conventional laminated glass. The substrate is placed flat, and the glass bricks are stacked on the horizontal plane. The vertical SGP films are used between the glass bricks to exert mutual extrusion force, completely changing the existing method of bricklaying in the vertical plane from bottom to top. Since the splicing glass prepared by this application has greater thickness and strength, it can be used as a transparent load-bearing glass brick wall material.

[0020] Using a flat glass as the substrate, which serves as the benchmark for stacking glass bricks, not only ensures verticality, but also makes the glass brick wall transparent, and can adjust the thickness of the glass brick wall. The substrate can be a single piece of glass or structural glass, such as double-layer or multi-layer laminated glass, which thickens the substrate without affecting its transparency, but can improve the strength. The number of layers of laminated glass can be determined according to needs; according to the design requirements or the required thickness for splicing glass, glass bricks can be stacked on one side or both sides of the substrate, and SGP glue is used for bonding on the contact surface of the glass bricks. In the preparation of conventional laminated glass, the glass is placed flat, and the SCP film sandwiched is also horizontal. However, in this application, in the connection between the glass bricks and the substrate, a large horizontal SCP film is used, which can ensure that the glass bricks are jointly bonded to the upper surface of the flat glass. In the connection between the glass bricks, small vertical SCP films are used, and the vertically laid films use films with a thickness of 2.28 mm. Compared with the conventional horizontal films with a thickness of 1.52 mm, they have better fluidity after entering the autoclave, improve the filling property, and ensure the bonding between the glass bricks.

[0021] If glass bricks are stacked on one side of the substrate, after stacking on the upper surface, the conventional laminated glass process is adopted, including wrapping the vacuum bag and entering the autoclave horizontally. First, vacuum treatment is carried out, and then high-temperature and high-pressure treatment is carried out to firmly bond the glass bricks to each other and the glass bricks to the substrate; if glass bricks are stacked on both sides of the substrate, after stacking on the upper surface, the laminated glass process is adopted to process the glass bricks on one side. At this time, after vacuuming, only high-temperature treatment without high-pressure treatment can be carried out to ensure the bonding of the glass bricks. After taking out of the autoclave, the glass is turned over and placed flat, and the glass bricks on the other side are stacked, and then the laminated glass process is adopted, first vacuuming, and high-temperature and high-pressure treatment to completely melt the SGP film, exhaust the bubbles completely, and ensure firm bonding.

[0022] This application changes the stacked glass bricks in the vertical plane to horizontal stacking of glass bricks, and changes the fixed bonding of the coating adhesive between the glass bricks to the sandwich SGP high-temperature and high-pressure treatment process between the glass bricks. At the same time, taking the substrate as the standard, it not only ensures the flatness of the spliced glass of the glass bricks, but also ensures the transparency of the entire spliced glass of the glass bricks, making the spliced glass prepared by this application have a stacked hierarchical three-dimensional sense and more ornamental value.

[0023] The splicing of the spliced glass of the glass bricks in this application has a sense of hierarchy. Under the lighting effect, each glass brick will flash, and it can reflect the inlaid effect of each one. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below in conjunction with the embodiments

[0030] The following laminated glass process and glass brick lamination process can refer to the Chinese patent of the applicant "High-pressure autoclave lamination method for extra-large laminated glass" (ZL2021111851816)

[0031] Embodiment 1

[0032] Glass brick spliced glass: 6864*964*98.56mm, fixed by a stainless steel frame around

[0033] Scheme: Splice glass bricks on both sides of the double-layer laminated glass, and leave a 28mm border around the double-layer laminated glass for fixing the stainless steel frame

[0034] Material preparation

[0035] Double-layer laminated glass: 1020*6920*25.52mm

[0036] Glass brick size: 964mm*35mm*50mm

[0037] Large SGP film size: 6864*964*1.52mm

[0038] Small SGP film size: 962mm*33mm*2.28mm

[0039] Splicing method process: See Figures 1 - 4 as shown

[0040] 1. First, complete the production of the double-layer laminated glass 1 according to the conventional process, see (ZL2021111851816). According to requirements, the size is 1020mm*6920mm; the position lines of the glass bricks are drawn on both end faces of the double-layer laminated glass with a marker pen according to the theoretical data required for the glass bricks

[0041] 2. Cut out the required small SGP film 4 (with dimensions of 962mm * 33mm * 2.28) according to the size of the glass bricks to be spliced.

[0042] 3. Take the completed double - laminated glass as the substrate, lay the glass flat, and lay a whole large SGP film 3 (1.52mm) on one side of the glass; then proceed with the splicing of the glass bricks 2. The size of each glass brick 2 is 964mm * 35mm * 50mm. First, take a glass brick and place it 28mm away from the four sides of the flat - laid double - laminated glass. Place a film mentioned in step 2 vertically against the glass brick. Then place a second glass brick closely against this film and then place the second cut - to - size film, and so on (see Figure 1 , Figure 2 ), and complete the placement of all the glass bricks. According to requirements, a total of 129 glass bricks are placed. During the placement of the glass bricks, arrange them neatly along the position lines.

[0043] 4. After the placement of the glass bricks on one side is completed, process the double - laminated glass 1 used as the substrate and the glass bricks 2 laid flat on its plane through an autoclave for lamination. Considering that there are 129 glass bricks in this glass splicing, with a large number and many splicing gaps, it greatly increases the risk of bubbles and poor adhesion during the autoclave processing. For this reason, the film vertically laid in the gap of each glass brick uses a film with a thickness of 2.28mm. Compared with the conventionally used film with a thickness of 1.52mm, the 2.28mm film has good fluidity after being put into the autoclave, improves the filling property, and ensures the adhesion between glass bricks and between glass bricks and the substrate glass. In addition, in order to avoid the generation of bubbles in the film, before entering the autoclave, the whole piece of spliced glass is subjected to vacuum treatment. To ensure the effect, the vacuum time can be longer. After these operations are completed, use the horizontal - into - autoclave method (i.e., the glass enters the autoclave horizontally) to perform high - temperature treatment or high - temperature and high - pressure treatment on the glass.

[0044] 5. After the glass comes out of the autoclave, turn the un - spliced side upwards. The process of splicing the glass bricks on this side is the same as that on the other side just now. First, lay a whole piece of film flat, and then place the glass bricks and the cut - to - size films in sequence..... After splicing, perform vacuum treatment and then put it into the autoclave. The number of glass bricks spliced on both sides is equal, with 129 on each side.

[0045] See Figure 3 , Figure 4 as shown.

[0046] There are three times of autoclave operations in the process of this application. The first time is for the double-layer glass to enter the autoclave, which is carried out according to the conventional method to ensure that the two pieces of glass are fully bonded. Then, glass bricks are laid on it, and the lamination work on the upper surface is completed according to the processing process described above. Then, the second autoclave operation is carried out. The purpose of this autoclave operation is to position all the glass bricks. The temperature is set at 110 degrees, and only vacuum is pumped without pressure, that is, to slightly melt the surface of the film and have a certain bonding effect to bond the glass bricks to the double-layer glass. Then, take it out of the autoclave, turn it over, and carry out the splicing and lamination of the glass bricks on the second side. Then, wrap it with a vacuum bag and tighten it, and enter the third autoclave. The temperature parameter is set to 135 degrees, and the pressure is increased to 1.25 MPa, so that the film between the glass bricks is fully melted, and the residual gas between the gaps is pumped out, so that the upper and lower layers of glass bricks are fully melted and bonded inside the film between them at the same time, which will not have any impact in the later stage. It is preferred to carry out the second autoclave operation without pressure and at a low temperature, as long as the interlayer film is slightly melted and has a bonding and fixing effect, so as to avoid the escape of the melted film.
