Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall connection structures, in particular to a novel curtain wall column structure connection structure. Background Art

[0002] At present, there are generally two types of structural connection forms for curtain wall columns, one is a single-span beam structure, and the other is a double-span beam structure.

[0003] The single-span beam structure is suitable for curtain wall structures with low floor heights. For large-span structures, the rod stress of the single-span beam may meet the requirements, but the deflection often does not meet the deflection control requirements of the L / 180 aluminum alloy rod. At this time, the general practice is to design the single-span beam as a double-span beam, increase the inter-layer supports, and reduce the span to achieve the purpose of reducing the rod stress and deflection. However, a necessary prerequisite for doing this is that the main structure must be able to meet the conditions for double supports. If the main structure beam is very short and cannot meet the conditions for double-span beams, there is another way to insert steel columns into aluminum alloy columns, and the steel-aluminum composite section is subjected to overall force. This is the so-called aluminum-clad steel curtain wall structure. Although this combined structure meets the calculation requirements to a certain extent, it has many disadvantages, such as:

[0004] 1. Consumables, both aluminum and a large amount of steel are consumed;

[0005] Second, the construction and installation are troublesome and inconvenient, and the production and installation costs are greatly increased;

[0006] 3. It is difficult to achieve synchronous deformation of steel and aluminum profiles. The steel and aluminum must be in close contact, but electrochemical reactions must be prevented between them. The two are themselves a pair of contradictory subjects.

[0007] Therefore, it is necessary to design a new type of curtain wall column structure connection structure, which can not only meet the structural requirements of large-span curtain walls, but also be simple and economical. Utility Model Content

[0008] The purpose of the utility model is to overcome the defects and shortcomings of the prior art, provide a novel curtain wall column structure connection structure, and solve various problems existing in the prior art.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A novel curtain wall column structure connection structure comprises a multi-span continuous beam structure vertically erected by multiple aluminum alloy columns, wherein upper and lower adjacent aluminum alloy columns are connected and transitioned by aluminum alloy inserts capable of transmitting bending moment, wherein the lower end of the aluminum alloy insert is inserted into the upper end of the lower aluminum alloy column, and the upper end of the aluminum alloy insert is inserted into the upper end of the lower aluminum alloy column, and an expansion joint is arranged between the upper and lower adjacent aluminum alloy columns, wherein the length of the aluminum alloy insert is greater than the sum of twice the maximum dimension of the column cross-section depth and the length of the expansion joint, and both the insertion length of the upper end of the aluminum alloy column and the insertion length of the lower end of the aluminum alloy column are not less than the maximum dimension of the column cross-section depth, and the lower end of the aluminum alloy insert is connected and fixed to an embedded part by a connector.

[0011] The first and top floors of the continuous beam structure have large spans, and the force requirements are met by increasing the support connection points.

[0012] An aluminum alloy insert is inserted into the bottom end of the aluminum alloy column of the first floor, and the lower end of the aluminum alloy insert is connected and fixed to the embedded part through a connecting piece.

[0013] The middle part of the aluminum alloy column on the top layer is connected and fixed to the embedded part through a connecting piece.

[0014] The embedded part includes a support embedded in concrete, and the support includes a longitudinal beam. The inner side of the longitudinal beam is connected to a plurality of spaced-apart transverse beams.

[0015] The connecting piece includes a connecting ear plate, and the two sides of the aluminum alloy column are respectively connected and fixed to the embedded parts through two connecting ear plates. The aluminum alloy column and the aluminum alloy insert are connected by bolts, and the corresponding positions of the aluminum alloy column and the aluminum alloy insert are respectively provided with connecting holes.

[0016] The outer side surface of the connecting ear plate is an outer tooth end surface, and the two ends of the bolt are respectively pressed and fixed to the ear plate through gaskets, and the inner end surface of the gasket is provided with an inner tooth end surface matching the outer tooth end surface.

[0017] A connecting sleeve is sleeved on the middle part of the aluminum alloy insert corresponding to the expansion joint, and protrusions for assisting the expansion joint in gluing and hanging glue are distributed on the outer surface of the connecting sleeve.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. By lengthening the aluminum alloy core and strengthening the connection, the aluminum alloy core and connectors connected at the aluminum alloy column can be bent, thereby reducing the peak bending moment. At the same time, the aluminum alloy profile can be optimized according to the minimum wall thickness, saving the consumption of aluminum profiles.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See attached Figure 1-6 ;

[0032] A novel curtain wall column structure connection structure, including a plurality of aluminum alloy columns 4 vertically erected with a multi-span continuous beam structure, the upper and lower adjacent aluminum alloy columns 4 are connected and transitioned by aluminum alloy inserts 1 that can transmit bending moments, the lower end of the aluminum alloy insert 1 is inserted into the upper end of the lower aluminum alloy column 4, the upper end of the aluminum alloy insert 1 is inserted into the upper end of the lower aluminum alloy column 4, an expansion joint 3 is arranged between the upper and lower adjacent aluminum alloy columns 4, and the length of the aluminum alloy insert 1 is greater than twice the maximum dimension of the cross-sectional depth of the aluminum alloy column 4 and the length of the expansion joint 3, and the insertion length of the upper end of the aluminum alloy column 4 and the insertion length of the lower end of the aluminum alloy column 4 are not less than the maximum dimension of the cross-sectional depth of the aluminum alloy column 4. Its main purpose is to strengthen the connection between the upper and lower columns so as to achieve the purpose of withstanding the bending moment at the connection position of the column. The lower end of the aluminum alloy insert 1 is connected and fixed to the embedded part 5 through the connecting part 6, wherein the embedded part 5 includes a support 8 embedded in the concrete 7, and the support 8 includes a longitudinal beam 81, and a plurality of spaced cross beams 82 are connected to the inner side of the longitudinal beam 81.

[0033] The length of the traditional aluminum alloy insert is not less than 250mm according to the requirements of 6.3.3 of "JGJ 102-2003 Glass Curtain Wall Engineering Technical Specifications"; as long as the upper and lower columns are rigid enough, it can be considered that the upper and lower column ends at the support connection can withstand the bending moment caused by the horizontal wind load of the curtain wall, and the upper and lower columns can be approximately considered as continuous beam structures. Moreover, the more spans of the continuous beam structure, the more beneficial it is to the structure. However, in general, the first and top floors of the continuous beam structure are large spans, so as long as the double supports are strengthened in the first span of the first floor and the top span of the top floor of the continuous beam, the force of the middle span is relatively ideal.

[0034] For ordinary buildings, the architectural design requirements are also designed to have a larger span on the first floor and the top floor, and the middle floor is a standard floor. Therefore, the stress model of the aluminum alloy column of the structure of this application is completely consistent with the general building model and has strong applicability.

[0035] If the strength and deflection of ordinary aluminum alloy columns do not meet the calculation requirements, the aluminum alloy columns can be designed as 6061-T6 high-strength aluminum alloy extruded profiles. The bending strength is about 35% higher than that of ordinary 6063-T6 aluminum alloy profiles, which meets the force requirements.

[0036] The stress of the standard layer in the structure of this application is relatively ideal. The column material is ordinary aluminum alloy profiles to meet the calculation requirements. As far as the standard layer is concerned, it has the following advantages:

[0037] 1. Save materials. Compared with the double-span beam connection and fixation method, the standard layer saves half of the support materials and connector materials shown in the figure; the standard layer uses ordinary aluminum alloy column profiles to meet the calculation requirements and does not need to be reinforced with steel core.

[0038] 2. Strong applicability. The higher the floor height, if the double-span beam uses pure aluminum alloy columns to meet the allowable requirements of rod stress and deflection, the short span often needs to be designed to be larger. If the short span is small, the mechanical model cannot be built into a real double-span beam. The length-to-short span ratio of a double-span beam should not be greater than 10. If the floor height is 4500mm, the short span is generally required to be about 500mm. However, if the beam is designed to be relatively small, the short span needs to be designed to be relatively large, and the length of the short span is greater than the beam height. At this time, the double-span beam does not meet the requirements, while the multi-span continuous beam only needs a single support for a single layer.

[0039] The present application achieves the purpose of allowing the rod connection to withstand the transmitted bending moment by lengthening and strengthening the aluminum alloy insert. At the same time, the bottom end of the aluminum alloy column 4 on the first floor is inserted with an aluminum alloy insert 1, and the lower end of the aluminum alloy insert 1 is connected and fixed to the embedded part 5 by a connector 6. The middle part of the aluminum alloy column 4 on the top floor is connected and fixed to the embedded part 5 by a connector 6. Therefore, the same approach is adopted for standard floors of the same level and span. If the standard floor spans are relatively large, double-span beams are appropriately designed at the middle layer position to increase the support connection points to form an over-statically determined structure to ensure the overall safety of the structure under stress. The utility model structural connection form is simple and convenient to implement, has strong applicability, is economical and safe, solves the pain points of large-span curtain wall column selection, and is worthy of large-scale promotion.

[0040] Furthermore, the connector 6 includes a connecting ear plate 61, and the two sides of the aluminum alloy column 4 are respectively connected and fixed to the embedded part 5 through two connecting ear plates 61, and the aluminum alloy column 4 and the aluminum alloy core 1 are connected through bolts 2, and the corresponding positions of the aluminum alloy column 4 and the aluminum alloy core 1 are respectively provided with connecting holes. The outer side surface of the connecting ear plate 61 is an outer tooth end face 62, and the two ends of the bolt 2 are respectively pressed and fixed to the connecting ear plate 61 through gaskets 63, and the inner end face of the gasket 63 is provided with an inner tooth end face 64 that matches the outer tooth end face. First, the aluminum alloy column 4 and the aluminum alloy core 1 are fixedly connected through the connecting ear plate, and the aluminum alloy core 1 is fixed, and then the connecting ear plate is fixed to the embedded part. When the bolts are connected, the connection and fixation are strengthened through the structure of the gasket and the tooth surface of the connecting ear plate 61.

[0041] Furthermore, a connecting sleeve 9 is mounted on the middle of the aluminum alloy insert 1 at the corresponding position of the expansion joint 3, and protrusions 10 for assisting the expansion joint gluing and hanging are distributed on the outer surface of the connecting sleeve 9. The structure of the connecting sleeve 9 facilitates the positioning of the aluminum alloy insert 1 during insertion, and the protrusion structure can increase the contact area with the expansion glue.

[0042] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0043] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
