Description

Technical Field

[0001] The present application relates to the technical field of building decoration construction, and in particular to a glass curtain wall installation structure, an elevator shaft and a construction method thereof. Background Art

[0002] As people's living standards improve, elevators are becoming increasingly popular. Many old civil buildings or villas do not meet the planning conditions for elevators due to their relatively low floors (according to the current national design standards: open stairs are designed for residential buildings with six floors or less); the existing residential infrastructure can no longer meet people's daily needs, so installing elevators for existing low-rise residential buildings has gradually formed a demand trend;

[0003] Elevator shaft construction is generally completed with the completion of building construction and is usually not restricted by the site or installation equipment. The construction method of the elevator shaft is roughly as follows: first install the elevator shaft frame structure, and then install the glass curtain wall on the four sides of the shaft frame structure; the specific installation methods are as follows: one method is to install the glass curtain wall on the shaft frame structure through stainless steel connecting claws, connecting parts and curtain wall connecting parts corner code; another method is to install the glass curtain wall on the shaft frame structure through profile moldings; another method is to install the glass curtain wall on the shaft frame through stainless steel fasteners.

[0004] The above installation methods have the following defects: they all require drilling and gluing on the four corners of the glass curtain wall, the installation process is time-consuming, and the glass curtain wall is easily damaged during drilling. The material cost is high, the operator's technical requirements are high, and it is difficult to replace the damaged glass later. Summary of the invention

[0005] In order to shorten the installation period and facilitate replacement, in the first aspect, the present application provides a glass curtain wall installation structure, an elevator shaft and a construction method thereof, adopting the following technical solutions:

[0006] A glass curtain wall installation structure, comprising:

[0007] A first base, wherein one end surface of the base is provided with an inwardly recessed groove;

[0008] A second base is spaced apart from the first base, and a stop surface is provided on an end surface opposite to the end surface where the groove is provided, the stop surface is bent relative to the end surface and together forms an angular open space;

[0009] The glass curtain wall unit has one end located in the groove of the first base, one side surface of the other end close to the stop surface of the second base, and the other side surface of the other end is fixedly connected to the end surface of the second base with the stop surface through a structural adhesive layer.

[0010] By adopting the above technical solution, during installation, one end of the glass curtain wall unit can be first inserted into the groove, and then the other end of the glass curtain wall unit can be directly pushed into the angular open space from the side facing the stop surface so that the glass curtain wall unit is tightly attached to the stop surface, and finally fixed by structural adhesive; there is no need to drill holes in the glass curtain wall unit, which reduces the damage caused by this. In addition, the above structural installation only needs to align the groove and insert it into it to apply glue, and does not require multiple alignment of stainless steel connecting claws, connecting parts and curtain wall connecting parts corner codes; the installation steps are simplified and the installation period is shortened. The shape of the glass curtain wall unit in this solution can be a rectangular, curved or other geometric shape, and multiple glass curtain wall units can be spliced ​​and surrounded to form a closed wall surface with two ends open.

[0011] Preferably, the first base and the second base are respectively arranged in a closed shape in their respective length directions.

[0012] By adopting the above technical solution, the closed device is adapted to the curtain wall shape of each layer of the elevator shaft frame, and the first base can be formed by splicing a plurality of straight or curved first base units end to end. Similarly, the second base can also be formed by splicing a plurality of straight or curved first base units end to end. The shapes of the first base and the second base in the length direction remain parallel, and this structure is conducive to its installation with the elevator shaft frame.

[0013] Preferably, the first base and the second base are respectively fixed on the plane frames of two adjacent layers of the elevator shaft frame; the glass curtain wall unit is installed between the plane frames of two adjacent layers to form a flat space.

[0014] By adopting the above technical solution, the first base and the second base can be prefabricated in advance. During installation, it is only necessary to install and fix the prefabricated parts on the plane frame beam of the elevator shaft, and then install the glass curtain wall unit. The above structure is easy to install.

[0015] Preferably, the first base is mounted on the upper plane frame, and the opening of the groove faces downward; the second base is mounted on the lower plane frame, and the open space faces outward.

[0016] By adopting the above technical solution, it is easier to apply the structural adhesive on the second base located on the lower plane frame than on the upper layer.

[0017] Preferably, a first base forming one flat space and a second base forming another flat space are fixedly connected or the integrally formed structure is supported on a plane frame and fixedly connected; the two flat spaces are arranged adjacent to each other.

[0018] By adopting the above technical solution, more time is saved compared to the separate installation of the first base and the second base.

[0019] Preferably, the overall structure is fixedly mounted on the outer side of the planar frame in a semi-enclosed shape, and the formed gap is located on the inner side of the planar frame.

[0020] By adopting the above technical scheme, the notch of the overall structure is adapted to the cross-sectional shape of the beam surrounding the plane frame. For example, the cross-section of the beam is square, and the semi-enclosed shape of the overall structure is a three-sided enclosed shape of the notch on one side, similar to the cross-section of the channel steel; the overall structure is clamped on the beam from the outside of the shaft space through the notch; for example, the cross-section of the beam is circular, and the semi-enclosed shape of the overall structure is semicircular; the semi-enclosed structure is a continuous wall structure, located outside the shaft space, and the junction surface of the notch and the beam is placed in the shaft space to protect it from erosion by the external environment, extend its service life and facilitate external cleaning; in addition, the above structure facilitates the installation of the prefabricated parts of the overall structure and the plane frame; the above fixed connection method can be connected by mechanical structure or welding process.

[0021] Preferably, it further comprises a plurality of connecting columns, each connecting column being installed on the outside of a column;

[0022] The overall structure is formed by connecting a plurality of units end to end;

[0023] Two ends of each unit are respectively fixed between two adjacent connecting columns.

[0024] By adopting the above technical solution, the part of the elevator shaft frame exposed outside the shaft space is wrapped by connecting the column, the first base and the second base and their integrally formed overall structure to form a protective shell. On the one hand, it protects the elevator shaft frame (usually made of carbon steel and other steel materials, which are easily oxidized and rusted after being exposed to wind and sun for a long time, affecting its service life). The protective shell can be made of corrosion-resistant materials, such as stainless steel, to extend the service life of the elevator shaft. On the other hand, it plays a decorative role, with a neat appearance and easy cleaning.

[0029] By adopting the above technical solution, prefabricated parts of the first base, the second base or the integrated structure of the two can be made before installation. During the construction process, it is only necessary to install the prefabricated parts on the plane frame and then install the glass curtain wall unit. Compared with installation methods such as connecting claw assemblies and profile strips, the installation steps are more convenient and the construction period is shorter.

[0036] Push the other end of the glass curtain wall unit into the angular open space of the second base from one side thereof, and make one side surface of the glass curtain wall unit contact the stop surface;

[0037] Apply structural adhesive between the other side surface of the glass curtain wall unit and the end surface of the second base provided with the stop surface, and after curing, form a structural adhesive layer, thereby completing the installation of the glass curtain wall unit and the installation structure;

[0038] Repeat the above process to complete the installation of all glass curtain wall units.

[0039] By adopting the above technical solution, there is no need to drill holes on the glass curtain wall unit, which reduces the damage caused by this. It is only necessary to align the groove, insert it and apply glue. There is no need for multiple alignment of stainless steel connecting claws, connecting parts and curtain wall connecting parts corner codes; the installation steps are simplified and the installation period is greatly shortened.

[0040] Preferably, the planar frame is formed by connecting a plurality of beams end to end; the steps of respectively installing the first base and the second base on the planar frame of the derrick include:

[0041] Prefabricate a first base and a second base as an integral structure; each integral structure cooperates with a beam;

[0043] The overall structure and the beam are welded at the notch to complete the fixation of the overall structure and the derrick;

DETAILED DESCRIPTION

[0057] The present application is further described in detail below in conjunction with the accompanying drawings.

[0058] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. After reading this specification, those skilled in the art can make modifications to the present embodiment without creative contribution as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law. In order to make the purpose, technical solution and advantages of the embodiment of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0059] The following is a further detailed description of an embodiment of the glass curtain wall installation structure of the present application in conjunction with the drawings in the specification and the elevator shaft.

[0060] Embodiment 1

[0061] An embodiment of the present application provides an elevator shaft, such as Figure 1 As shown, the elevator shaft includes an elevator shaft frame 1 and a plurality of glass curtain wall installation structures 2 installed on the shaft frame; the shaft frame 1 includes a plurality of columns 10 and a multi-layer plane frame 20, the plurality of columns 10 are arranged in parallel, and the multi-layer plane frame 20 is fixed in the space enclosed by the plurality of columns 10 at intervals along the height direction of the columns; in a specific scheme of the present application, four columns 10 are included, which together enclose a rectangular shaft space; the plane frame 20 is rectangular and arranged along the cross-sectional direction of the shaft space, and is alternately fixed head to tail on the four columns 10 by two cross beams 21 and two longitudinal beams 22. The glass curtain wall installation structure 2 is installed on a rectangular side frame formed by two adjacent layers of plane frames 20 and two columns.

[0062] See also Figure 3The glass curtain wall mounting structure 2 includes a first base 41, a second base 42 and a glass curtain wall unit 30. The first end surface 41a of the first base 41 is provided with an inwardly recessed groove 41b for clamping one end of the glass curtain wall unit 30 therein; the second base 42 is spaced apart from the first base 41, and a stop surface 42b is provided on the second end surface 42a opposite to the first end surface 41a where the groove 41b is provided, and the stop surface 42b is bent relative to the second end surface 42a and enclosed together to form an open space; it is used to place the other end of the glass curtain wall unit 30 on the second end surface 42a from one side so that one side of the glass curtain wall unit 30 abuts against the stop surface 42b, and the other side of the glass curtain wall unit 30 is fixedly connected to the second base 42 through a structural adhesive layer 43.

[0063] During installation, first, one end of the glass curtain wall unit 30 is placed into the groove 41b, and then the other end is pushed into the open space on the second end face 42a from the opening side thereof and abutted against the stop face 42b, and then the structural adhesive is applied between the end of the glass curtain wall unit and the second end face 42a, and a structural adhesive layer 43 is formed after the structural adhesive solidifies. In order to improve the sealing performance and structural stability, the structural adhesive can be applied between the height direction of the column 10 and the side edge of the glass curtain wall and solidified to form a structural adhesive layer, thereby completing the installation of each glass curtain wall unit 30. Repeat the above process to realize the construction of the elevator shaft. The above installation structure does not require drilling holes on the glass curtain wall unit 30, which simplifies the installation steps on the one hand, and reduces the damage of the curtain wall unit caused by this on the other hand, speeds up the installation process, and greatly shortens the construction period. Taking the construction of the elevator shaft of a six-story civil building as an example, the relevant technology requires a construction period of about six months. This solution shortens the construction period to a quarter of the previous construction period, that is, the construction can be completed in one and a half months.

[0064] During the construction process, in order to prevent the glass curtain wall unit from tipping in the direction away from the stop surface 42b during the construction of the structural adhesive layer 43. In one embodiment of the present application, a rubber pad is placed on the second end surface 42a, which can be adsorbed on the second end surface 42a, and when the glass curtain wall unit 30 is placed thereon, it can be deformed due to the gravity of the glass curtain wall unit 30, thereby clamping the glass curtain wall unit 30 between the groove 41b and the second end surface 42a and the stop surface 42b. In order to further increase the stability of the installation structure, an inverted U-shaped rigid anti-slip sheet can be welded on the outside of the first base, the second base or the column to prevent the glass curtain wall unit from detaching from the elevator shaft frame.

[0065] In another embodiment of the present application, see Figure 2, the stop surface 42b faces outward (the direction away from the elevator shaft space is the outside, and the direction close to the shaft space is the inside), the inner side of the glass curtain wall unit is close to the stop surface 42b, and the outer side is fixedly connected to the second end surface 42a of the second base 42 through the structural adhesive layer 43. When the glass curtain wall is attacked by external forces such as typhoons from the outside, the bottom makes it close to the stop surface 42b, and the top is restricted by the groove 41b. When it is attacked by external forces inside, the top is restricted by the groove 41b, and the bottom is restricted by the structural adhesive layer 43. The top of the glass curtain wall unit is limited in the groove 41b, and the bottom is limited between the stop surface 42b and the structural adhesive layer 43, and the two sides are in conflict with the column 10.

[0066] In another embodiment of the present application, see Figure 3 , the stop surface 42b faces inward (the direction away from the elevator shaft space is the outside, and the direction close to the shaft space is the inside), the outer side surface of the glass curtain wall unit is close to the stop surface 42b, and the inner side surface is fixedly connected to the second end surface 42a of the second base 42 through the structural adhesive layer 43. When the glass curtain wall is attacked by external forces such as typhoons from the outside, the bottom is restricted by the structural adhesive layer 43, and the top is restricted by the groove 41b. When it is attacked by external forces from the inside, the top is restricted by the groove 41b, and the bottom makes it close to the stop surface 42b. The top of the glass curtain wall unit is confined in the groove 41b, and the bottom is confined between the stop surface 42b and the structural adhesive layer 43, and the two sides are in conflict with the column 10.

[0067] In one embodiment of the present application, see Figure 2 The first base 41 and the second base 42 are respectively enclosed in a closed shape in their respective length directions. The closed shape can be a rectangle, a circle, an ellipse, a regular polygon or other geometric shapes. In one embodiment of the present application, the first base 41 or the second base 42 can be formed by connecting multiple base units end to end to form a closed shape.

[0068] Preferably, the first base 41 and the second base 42 are respectively fixed on the adjacent plane frames of the elevator shaft frame; the glass curtain wall unit 30 is installed between the adjacent plane frames to form a flat space.

[0069] In another embodiment of the present application, the first base 41 or the second base 42 can directly set the angle structure formed by the groove 41b of the first base 41 or the second end face 42a and the stop face 42b in the second base 42 on a structural member (such as a planar frame of an elevator shaft), and the structural member is in a closed shape.

[0070] Preferably, for the convenience of installation, the first base 41 is installed on the upper plane frame, and the opening of the groove 41b is downward; the second base 42 is installed on the lower plane frame, and the open space is outward. In the above-mentioned installation structure, during construction, the operator inserts the top of the glass curtain wall unit into the groove 41b from bottom to top, and then places the bottom of the glass curtain wall unit on the second end face 42a, and makes it close to the stop face 42b inward, and then operates the clamping structure to apply thrust from the outside to make the glass curtain wall unit close to the installation structure, so as to prevent the glass curtain wall unit from being separated from the installation structure due to the influence of environmental external forces in the subsequent glue coating process, thereby affecting the curing of the glue layer, and finally, the structural glue is applied between the bottom of the glass curtain wall unit and the second end face 42a, and after it solidifies, a structural glue layer 43 is formed to complete the connection between the glass curtain wall unit and the installation structure; in order to improve the sealing and stability, structural glue or sealant can be applied between the two sides of the glass curtain wall unit and the column 10 and between the top of the glass curtain wall unit and the first end face 41a.

[0071] Preferably, a first base 41 forming one flat space and a second base 42 forming another flat space are fixedly connected or an integral structure 40 is supported on the plane frame 20 and fixedly connected; the two flat spaces are adjacently arranged.

[0072] The first base 41 and the second base 42 mounted on the intermediate plane frame 20 of the elevator shaft frame can be set as an integrated structure (integral structure 40), see Figure 3 During installation, the above-mentioned integrated structure can be placed on the cross beam 21 and the longitudinal beam 22 from the notch 40a, and the opening and the exposed cross beam 21 and longitudinal beam 22 are welded and fixed to realize the connection between the integrated structure and the plane frame 20; see FIG. 4, Figure 5 The second base 42 is installed separately at the bottom of the elevator shaft frame 1, and the first base 41 is installed separately at the top plane frame 20. This integrated structure can speed up the installation process of the installation structure and the elevator shaft frame, shorten the construction period; and the structure has higher stability.

[0073] Preferably, the integral structure 40 or the one-piece structure is formed with a notch 40 a , and the integral structure 40 is installed on the outer side of the planar frame 20 in a semi-enclosed shape; the notch 40 a is located on the inner side of the planar frame 20 .

[0074] The longitudinal opening size of the notch 40a is equal to or slightly larger than the height of the longitudinal beam or the cross beam, and the transverse direction of the notch runs through the length direction of the overall structure, and the welding is completed from the inside; the above structure makes the weld of the overall structure inside the elevator shaft structure, which makes the external structure more neat and beautiful on the one hand, and protects the weld from the external environment on the other hand. Furthermore, a panel made of the same material as the overall structure (generally stainless steel) can be welded at the notch position to prevent dust and other stains from remaining in the notch during use, which is difficult to clean.

[0075] Preferably, see Figure 2 , and also includes a plurality of connecting columns 44, each connecting column 44 is installed outside a column 10; the overall structure is formed by connecting a plurality of units end to end; the two ends of each unit are respectively fixed between two adjacent connecting columns 44. The connecting column 44 is also made of stainless steel, and is semi-enclosed and buckled on the periphery of the column, and the open side is welded to the column 10. In one embodiment of the present application, see Figure 2 The cross section of the column 10 is square, two adjacent sides of the column 10 are connected to the cross beam and the longitudinal beam respectively, and the connecting column 44 at least surrounds the other two sides of the column 10 that are not connected to the longitudinal beam and the cross beam. After the installation of this structure, the external whole presents a seamless structure, which has a protective effect on the internal components and is also easy to clean.

[0076] Embodiment 2

[0077] Based on the same inventive concept as above, see Figure 3 The present application also provides a glass curtain wall installation structure, which is the structure of any embodiment of the glass curtain wall installation structure in the elevator shaft. The use and effect refer to the above embodiment and will not be repeated.

[0078] Embodiment 3

[0079] Based on the same inventive concept above, the embodiment of the present application also provides an elevator shaft construction method, comprising the following steps:

[0080] S10, installing the elevator shaft frame 1 on the completed foundation;

[0081] The construction of the elevator shaft frame 1 can be completed by a known construction method, such as a support platform, a scaffold, etc. that is lifted along with the construction of the main structure of the building. The construction sequence of the shaft frame here is from low to high.

[0082] S20, respectively installing a first base 41 and a second base 42 on a plane frame 20 of the elevator shaft frame 1, wherein the plane frame is formed by connecting a plurality of beams (including a cross beam 21 and a longitudinal beam 22) end to end; comprising:

[0083] S21, prefabricate the integral structure 40 of the first base and the second base formed in one piece and the first base prefabricated structure (see Figure 4 ) and the second prefabricated base structure (see Figure 5 ); Each integral structure 40 cooperates with a beam;

[0084] It should be noted that the prefabrication step can be completed in advance as a prefabricated part before the construction of the elevator shaft; since the plane frame located at the top layer and the plane frame located at the bottom layer only need to install the glass curtain wall unit in a single direction, only the prefabricated parts of the first base or the second base need to be installed on these two plane frames separately, without the need to install the above-mentioned prefabricated structure.

[0085] S22, placing the overall structure, the first prefabricated base structure, and the second prefabricated base structure on a beam along the notch from the outside thereof in a construction order;

[0086] The construction sequence here can be from low to high. For example, after completing the construction of the first-layer derrick, the second base prefabricated parts can be installed on the beams of the first-layer plane frame, and the first base and the second base can be installed on the beams of the second-layer plane frame (the welding and fixing of step S23 can be performed later); as the construction of the second-layer derrick is completed, the first base and the second base can be installed on the beams of the third-layer plane frame (the welding and fixing of step S23 can be performed later); repeat the above process until the construction of the highest layer, such as the sixth-layer derrick, is completed, and the first base prefabricated parts are installed on the beams of the seventh-layer plane frame (the welding and fixing of step S23 can be performed later).

[0087] S23, welding the overall structure, the first base prefabricated structure, the second base prefabricated structure and the beam from the notch to complete the fixing of the installation structure and the derrick;

[0088] All prefabricated structures have the above-mentioned notches for clamping on the beams, and then the prefabricated parts are fixed to the derrick beams by welding. The prefabricated parts can be made of stainless steel;

[0089] S24, repeating the above placement step S22 and welding step S23 to complete the fixing of all the overall structures and the derrick;

[0090] In order to improve the overall protection function of the elevator shaft, the steps of installing connecting columns outside the columns are also included:

[0091] S30, first prefabricate the bent connecting column, preferably also made of stainless steel, which can be carried out crosswise with S20, for example: after the construction of the first layer of the derrick is completed, the second base prefabricated parts are respectively installed on the beams of the first layer of the plane frame, the second base prefabricated parts and the beams are fixed by spot welding, the two ends of the second base prefabricated parts are respectively fixed to the two ends of the columns, the connecting column prefabricated parts are respectively installed on the four columns and welded to fix them, and the connecting column prefabricated parts and the two ends of the second base prefabricated parts are welded to fix them; the construction sequence of the connecting column and the base prefabricated parts can also be exchanged: after the construction of the first layer of the derrick is completed, the connecting column prefabricated parts are respectively installed on the four columns and welded to fix them, and then the second base prefabricated parts are respectively installed on the beams of the first layer of the plane frame, the second base prefabricated parts and the beams are fixed by spot welding, and the two ends of the second base prefabricated parts are respectively fixed to the two ends of the connecting column prefabricated parts; the same as above, on the second layer of the plane The integral structural prefabricated parts formed as one piece of the first base and the second base are respectively installed on the beams of the frame and spot welded to fix them, and the two ends of the integral structural prefabricated parts are respectively fixed to the two ends of the connecting column prefabricated parts; as the construction of the second-layer derrick is completed, the integral structural prefabricated parts formed as one piece of the first base and the second base are respectively installed on the beams of the third-layer plane frame and spot welded to fix them, and the two ends of the integral structural prefabricated parts are respectively fixed to the two ends of the columns; the connecting column prefabricated parts are respectively installed on the four columns and welded to fix them, and the connecting column prefabricated parts are welded to the two ends of the integral structural prefabricated parts; the construction sequence of the connecting columns and the integral structural prefabricated parts can also be exchanged, and no further details will be given. The above process is repeated until the construction of the highest layer, such as the sixth-layer derrick, is completed, and the first base prefabricated parts are respectively installed on the beams of the seventh-layer plane frame and welded to fix them, and the two ends of the first base prefabricated parts are respectively fixed to the two ends of the connecting column prefabricated parts.

[0092] When the connecting column prefabricated member and the column are an integrated structure, the above step S30 can be omitted. Similarly, when the first base and the second base are an integrated structure with the plane frame, the above step S20 can be omitted.

[0093] S40, installing the glass curtain wall unit 30 between the first base 41 and the second base 42 respectively, including:

[0094] It should be noted that this step can be performed in conjunction with the above step S20. After the prefabricated parts are fixed to the first and second layer plane frames, S41 to S43 can be performed.

[0095] S41, placing one end of the glass curtain wall unit into the groove of the first base;

[0096] If the first base prefabricated component is installed at the top of each layer of the derrick, the top of the glass curtain wall unit is placed in the groove from bottom to top; if the first base prefabricated component is installed at the bottom of each layer of the derrick, the bottom of the glass curtain wall unit is placed in the groove from top to bottom.

[0097] S42, pushing the other end of the glass curtain wall unit into the angular open space of the second base from one side thereof, and making one side surface of the glass curtain wall unit contact the stop surface;

[0098] Taking the case where the first base prefabricated part is installed on the top of each layer of the derrick as an example, it should be noted that after the glass curtain wall unit is installed, there is a gap between the top and the bottom surface of the groove (gap in the height direction), and there is also a gap between the top side and the side wall of the groove (gap in the thickness direction). These two gaps are used to meet the installation requirements, but the gap in the height direction is smaller than the depth of the groove. A part of the top of the glass curtain wall unit is confined in the groove to prevent it from being separated from the installation structure from both sides; the bottom of the glass curtain wall unit is pushed from the side of the second end face of the second base facing the stop face into the open space formed by the second end face and the stop face and gradually approaches the second stop face until it is completely close; the right-angled open space formed by the second end face of the second base and the stop face cooperates with the groove structure of the first base, on the one hand, so that the above-mentioned glass curtain wall unit can be placed directly from the outer space of the shaft space, without being limited to the internal space of the shaft; on the other hand, there is no need to drill holes in the glass curtain wall unit panel; if subsequent damage occurs and a single piece needs to be replaced, it is also easy to achieve without dismantling other structures.

[0099] S43, coating structural adhesive between the other side surface of the glass curtain wall unit and the end surface of the second base provided with the stop surface, and forming a structural adhesive layer after curing, thereby completing the installation of the glass curtain wall unit and the installation structure;

[0100] Structural adhesive can be purchased directly from the market. It has high strength (compression strength>65MPa, steel-steel tensile bonding strength>30MPa, shear strength>18MPa), can withstand large loads, and is resistant to aging, fatigue, and corrosion. It has stable performance within the expected service life and is suitable for bonding strong structural parts. It has been tested many times to meet the strength requirements. In order to further improve the strength and sealing effect, structural adhesive can be coated between the inner and outer sides and the frame respectively.

[0101] During this construction process, in order to improve safety performance, a clamping mechanism can be installed on the derrick to apply thrust to the glass curtain wall unit from the outside so that it continues to contact the stop surface, preventing it from being separated from the installation structure due to external environmental forces or its own weight during the glue coating construction process, thereby affecting the solidification and fixation of the structural adhesive layer.

[0102] S44, repeat the above process to complete the installation of all glass curtain wall units.

[0103] With the installation of the derrick and mounting structure, the installation of glass curtain wall units is gradually realized from low to high floors.

[0104] As described above, the above embodiments are only used to introduce the technical solution of the present application in detail, but the description of the above embodiments is only used to help understand the method and core idea of ​​the present application and should not be understood as limiting the present application. Any changes or substitutions that can be easily thought of by technicians in this technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application.
