Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall construction, and more specifically, to a construction method for a curtain wall suspension structure. Background Art

[0002] In the prior art, when hanging the rectangular ceramic tiles in a loop shape, holes are often drilled on the rectangular ceramic tiles in a loop shape, and then the rectangular ceramic tiles in a loop shape are assembled in cooperation with the round steel columns installed on the main structure; this method is used to ensure that the round steel columns can bear the load of the rectangular ceramic tiles in a loop shape, and the round steel columns will be segmented, that is, the round steel columns will be fixed with keels to ensure their stability; during installation, the rectangular ceramic tiles in a loop shape can only be sleeved on the outside of the round steel columns through through holes from the top of the round steel columns; this makes the installation extremely inconvenient. Drilling holes in the rectangular ceramic tiles in a loop shape is very likely to cause damage during the hole drilling process. At the same time, the connection method of sleeve connection is not stable enough. Especially in earthquake-prone areas, the vibration effect generated by the earthquake is very likely to cause damage to the rectangular ceramic tiles in a loop shape. Summary of the Invention

[0047] The present invention will be described in detail below.

[0048] As Figures 1-5 shown: On the one hand:

[0049] The present invention discloses a curtain wall suspension structure, which includes a prestressed cable structure with its upper and lower ends respectively connected to the main structure 1, and a fixture structure 4 sleeved outside the prestressed cable structure and connected to the curtain wall.

[0050] The fixture structure 4 is mainly used for suspending, supporting and fixing the curtain wall.

[0051] During use, first, according to the size of the entire curtain wall to be installed, the total weight of the curtain wall, and the size of a single curtain wall unit, parameters such as the diameter and bearing capacity of the prestressed cable structure are determined, so that the prestressed cable structure can bear the weight of the curtain wall after installation; then the installation of the prestressed cable structure is carried out; after the installation of the prestressed cable is completed, the installation of the fixture structure 4 and the curtain wall is carried out; adopting the above technical solution, compared with the prior art, there is no need to set additional support members, which simplifies the installation method; there is no need to perform hole-opening treatment on the curtain wall, and it can be connected to the prestressed cable through the fixture structure 4; the installation is more simple and convenient.

[0052] In some possible implementation manners, in order to effectively realize the connection between the fixture structure 4, the prestressed cable structure and the curtain wall;

[0053] The fixture structure 4 includes two sets of fixture monomers 41 with the same structure and symmetrically arranged along the prestressed cable structure, and connection components 42 respectively connected to the fixture monomers 41 and the curtain wall;

[0054] The two sets of fixture monomers 41 are closed to form a through hole 410 sleeved outside the prestressed cable;

[0055] The two sets of fixture monomers 41 are connected by tie bolts 413 and form a through hole 410 on the side close to each other. The through hole 410 is in interference fit with the prestressed cable structure 3 to achieve connection and fixation; it is ensured that the fixture body formed by the two sets of fixture monomers 41 will not move vertically;

[0056] In some possible implementation manners, in order to effectively realize the connection between the connection component 42 and the fixture monomer 41;

[0057] A vertical plate 412 connected to the connection component 42 is provided at the top of the fixture monomer 41.

[0058] In some possible implementation manners, in order to effectively realize the connection between the connection component 42 and the vertical plate 412;

[0059] The vertical plates 412 on the two sets of fixture monomers 41 cooperate with the top of the fixture monomer 41 to form an installation chamber 411;

[0060] The connection component 42 includes a plug-in portion 421 that is inserted into the vertical plate 412 and is located on the side of the vertical plate 412 away from the fixture unit 41, and a connecting member 422 that connects the plug-in portion 421 and the curtain wall on the side close to the fixture unit 41;

[0061] One side of the connecting member 422 away from the plug-in portion 421 abuts against the fixture unit 41.

[0062] In some possible implementation manners, in order to prevent the plug-in portion 421 from sliding after installation;

[0063] The vertical plate 412 is provided with threaded holes 4121 along the axial direction of the prestressed cable, and the plug-in portion 421 is screwed to the vertical plate 412.

[0064] After the plug-in portion 421 is inserted into the vertical plate 412, the plug-in portion 421 and the vertical plate 412 are fixed by the cooperation of bolts and the threaded holes 4121, so as to prevent displacement between the two during use and prevent sliding;

[0065] In some possible implementation manners, in order to facilitate hard contact between the connection component 42 and the fixture unit 41, and between the connection component 42 and the curtain wall, and cause damage to the curtain wall under the action of an earthquake or other external forces;

[0066] Buffer gaskets 43 are respectively arranged between the vertical plate 412 and the plug-in portion 421, and between the connecting member 422 and the curtain wall; two buffer gaskets 43 in the same group of plug-in portions 421 cooperate with the vertical plate 412 to install the slots of the profile groove.

[0067] The buffer gasket 43 can, on the one hand, prevent slipping and avoid noise and stress caused by rigid contact; on the other hand, prevent electrochemical reactions from occurring between different metals and causing corrosion.

[0068] The vertical plate 412 is located in the slot and abuts against the two buffer gaskets 43. The buffer gasket 43 is made of an elastic material such as rubber or silica gel, which can effectively buffer under the action of external forces and avoid extrusion deformation of the connection component 42 and the fixture unit 41, thereby causing damage to the curtain wall.

[0069] In some possible implementation manners, in order to ensure the installation of the buffer gasket 43;

[0070] The plug-in portion 421 is provided with a T-shaped groove 4211 near the vertical plate 412, and its small end is open; the buffer gasket 43 includes a connecting portion installed in the T-shaped groove 4211 and a buffer portion connected to the connecting portion and abutting against the vertical plate 412.

[0071] The T-shaped groove 4211 is a through groove, which avoids the installation of the buffer gasket 43 and is arranged in the horizontal direction.

[0072] The insertion part 421 is provided with an opening groove, the opening of the opening groove faces downward and is inserted into the vertical plate 412; T-shaped grooves 4211 are arranged on both sides of the opening groove, the small ends of the T-shaped grooves 4211 are open, and the openings are arranged close to one side of the vertical plate 412, and the connecting part is installed in the T-shaped groove 4211; and it passes through the opening of the T-shaped groove 4211 and is connected to the buffer part; the buffer part will effectively ensure that under the action of external forces, such as during an earthquake, it can effectively prevent the insertion part 421 and the vertical plate 412 from shaking and deforming due to mutual extrusion, thereby causing damage to the curtain wall.

[0073] Preferably, T-shaped grooves 4211 are also arranged on the side of the connecting piece 422 close to the fixture unit 41, and buffer gaskets 43 are installed.

[0074] Furthermore, the connecting piece 422 and the curtain wall are connected by bolts.

[0075] In some possible implementation manners, in order to realize the connection between the curtain wall and the fixture structure 4;

[0076] The curtain wall includes a structure one 10 connected to the side of the fixture structure 4 close to the indoor side and a structure two 20 connected to the side of the fixture structure 4 far from the indoor side. The structure one 10 and the structure two 20 cooperate with each other to form a fixing cavity 30 sleeved on the outside of the fixture structure 4.

[0077] In the present invention, as Figure 5 shown, the curtain wall is divided into two pieces, and the connection with the prestressed cable structure 3 is realized through the connection of the connection components 42 respectively connected to two groups of symmetrically arranged fixture units 41.

[0078] The main purpose of setting the structure one 10 is that when the position of the main structure 1 corresponding to the curtain wall is glass, it will greatly increase its aesthetic degree. When the position of the main structure 1 corresponding to the curtain wall is a wall, the structure one 10 can be not set, and it can be mainly configured according to the on-site construction.

[0079] Preferably, there are two groups of fixing cavities 30, and the fixture structure 4 is installed in the fixing cavities 30; two groups of fixture bodies will be arranged in each fixing cavity 30; this will ensure the firmness of the installation.

[0080] Of course, the fixing cavities 30 can also be three groups, four groups or more groups; the fixture bodies in each fixing cavity 30 can also be multiple groups, and it can be mainly selected according to the on-site construction needs.

[0081] In some possible implementation manners,

[0082] The prestressed cable structure 3 includes two groups of symmetrically arranged cable heads, a cable body arranged vertically and connected to the two groups of cable heads at both ends, and connecting plates 2 respectively connected to the two groups of cable heads and fixed on the main structure 1.
