Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall brackets, in particular to a keel frame for supporting building curtain walls. Background Art

[0002] The curtain wall keel is an important component used to support and fix the building curtain wall system. Its main function is to bear the deadweight and external load of the curtain wall system and transfer it to the building structure to ensure the stability and safety of the curtain wall system.

[0003] When the curtain wall keel is fixed to the exterior of the building, it is often fixed to the building wall by directly driving expansion bolts. However, driving expansion screws can easily damage the building wall structure and cause damage to the building structure. The curtain wall keel is also fixed to the building wall only by expansion bolts, which also has the problem of insufficient installation stability. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and provides a keel frame which has a stable structure, is easy to install and will not damage the wall structure.

[0005] The utility model is realized through the following technical scheme: a keel frame for supporting a building curtain wall, comprising a vertical keel clamped with a building support outer beam, and a horizontal keel hung on the vertical keel, wherein the outer side of the support outer beam is provided with an outwardly protruding clamping block, the inner side of the vertical keel is provided with a clamping piece clamped and fixed with the clamping block, the inner side of the horizontal keel is provided with a hanging piece, and the outer side of the vertical keel is provided with a hook for hanging the hanging piece.

[0006] In this solution, the vertical purlins are fixed to the blocks on the supporting outer beams through the clamping parts, and the horizontal purlins are then hung on the outside of the vertical purlins through the hanging parts. The curtain wall can be installed, avoiding the damage to the building wall caused by the fixing method of expansion bolts and is easy to install.

[0007] As an optimization, the clamping piece and the vertical keel are connected by connecting bolts, and the vertical keel is provided with bolt holes for the connecting bolts to pass through. This optimization solution allows the clamping piece to be clamped to the clamping block first, and then the vertical keel to be bolted to the clamping piece, which facilitates the clamping of the clamping piece and the installation of the vertical keel.

[0008] As an optimization, the cross-section of the clamping block is a right-angled trapezoidal structure, the hypotenuse of which is inclined upward and forms the top of the clamping block. The clamping member includes a first vertical plate, a first inclined plate and a first horizontal plate fixed to the upper and lower ends of the first vertical plate. The first vertical plate, the first inclined plate and the first horizontal plate are respectively in contact with the outer side, top and bottom of the clamping block. This optimization solution optimizes the clamping member structure and is easy to process. After the clamping member is clamped to the clamping block, the top of the clamping block is an inclined surface that is in contact with the first inclined plate of the clamping member, thereby achieving the clamping of the two. This prevents the clamping member from separating from the clamping block when bearing weight, and improves the stability and connection strength of the clamping member in the vertical direction.

[0009] As an optimization, both the outer side of the clamping block and the first vertical plate are provided with retaining holes, and retaining posts are fixedly attached to the inner side of the vertical keel, sequentially passing through the two retaining holes. In this optimized solution, the vertical keel, the clamping member, and the clamping block are restrained by the retaining posts, preventing the vertical keel from shifting in the left and right directions, further improving the stability of the vertical keel after installation.

[0010] As an optimization, the outer support beam includes a vertically intersecting support beam and a vertical support beam, and the clamping block is located at the intersection of the support beam and the vertical support beam. This optimization solution improves the support strength of the outer support beam on the keel.

[0011] As an optimization, the hanging part includes a first cross bar parallel to the transverse keel, and a plug-in gap is provided between the first cross bar and the transverse keel. Both ends of the first cross bar are fixed to the inner side of the transverse keel through connecting plates, and the spacing between the two connecting plates is not less than the width of the vertical keel.

[0012] As an optimization, an L-shaped groove is formed inwardly on the outer side of the vertical keel. The vertical side of the L-shaped groove is located at the end of the horizontal side away from the horizontal keel and extends downward. The raised structure between the outer side of the vertical keel and the vertical side of the L-shaped groove forms the hook. This optimization solution optimizes the hook structure, and the hook is engaged in the insertion gap to achieve the connection of the horizontal keel.

[0013] The beneficial effects of the utility model are as follows: the vertical keels are fixed to the clamping blocks on the supporting outer beams through the clamping pieces, and then the transverse keels are hung on the outside of the vertical keels through the hanging pieces, so that the curtain wall can be installed, avoiding the damage to the building wall structure caused by the fixing method of expansion bolts, and the installation is convenient, the structure is stable, and the connection strength is higher.

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0023] like Figures 1 to 6 As shown, a keel frame for supporting a building curtain wall comprises a vertical keel 2 which is clamped to a supporting outer beam 1 of the building, and a horizontal keel 3 which is hung on the vertical keel 2. An outwardly protruding clamping block 13 is provided on the outer side of the supporting outer beam 1, and a clamping part 4 which is clamped and fixed to the clamping block 13 is provided on the inner side of the vertical keel 2.

[0024] Specifically, the outer support beam 1 comprises a vertically intersecting horizontal support beam 12 and vertical support beam 11, with the block 13 positioned at the intersection of the horizontal and vertical support beams 12 and 11. The block 13 has a right-angled trapezoidal cross-section, with the hypotenuse sloping upward to form the top of the block. In this embodiment, the outer support beam 1 is positioned outside the building foundation wall, and the outer support beam and block 13 are integrally formed.

[0025] The clamping member 4 includes a first vertical plate 41, a first inclined plate 42, and a first horizontal plate 43 fixed to the upper and lower ends of the first vertical plate 41. The first vertical plate, first inclined plate, and first horizontal plate respectively mate with the outer side, top, and bottom of the clamping block 13. The clamping member 4 is connected to the vertical keel 2 via connecting bolts 8. The vertical keel 2 has bolt holes 9 for the connecting bolts 8 to pass through. In this embodiment, the clamping member is evenly distributed with four connecting bolts 8, which are welded to the outer side of the first vertical plate 41 of the clamping member.

[0026] Limiting holes 7 are provided on the outer side of the clamping block 13 and the first vertical plate 41. Limiting columns 6 are fixed to the inner side of the vertical keel 2 and pass through the two limiting holes 7 in sequence. The limiting columns 6 limit the clamping part 4 to prevent the clamping part from being displaced. At the same time, it is convenient to align the connecting bolts 8 with the bolt holes 9 on the vertical keel, thereby facilitating the installation of the vertical keel.

[0027] A hanging piece 5 is provided on the inner side of the transverse keel 3 , and a hook for the hanging piece 5 to be hung is provided on the outer side of the vertical keel 2 .

[0028] Specifically, the hanging member 5 includes a first cross bar 51 parallel to the transverse keel 3, and a plug-in gap is provided between the first cross bar 51 and the transverse keel 3. Both ends of the first cross bar 51 are fixedly connected to the inner side of the transverse keel 3 through connecting plates 52, and the distance between the two connecting plates 52 is not less than the width of the vertical keel 2.

[0029] An L-shaped groove 101 is provided on the outer side of the vertical keel 2. The vertical side of the L-shaped groove is located at the end of the horizontal side away from the transverse keel 3 and extends downward. The raised structure between the outer side surface of the vertical keel 2 and the vertical side of the L-shaped groove forms the hook 10. The width of the hook is adapted to the width of the insertion gap. The height of the transverse side of the L-shaped groove is adapted to the height of the first cross bar 51. The width of the vertical side of the L-shaped groove is adapted to the width of the first cross bar 51. The first cross bar 51 is inserted into the L-shaped groove 101, so that the hook 10 is clamped in the insertion gap to realize the hanging of the transverse keel 3.

[0030] During installation, first, the clamping piece 4 and the clamping block 13 are engaged and fixed, and then the vertical purlin 2 and the connecting bolts 8 fixed on the clamping piece 4 are connected. During connection, the limiting column 6 on the inner side of the vertical purlin 2 is sequentially passed through the limiting holes 7 on the first vertical plate 41 and the clamping block 13. At this time, the connecting bolt 8 is also aligned with the bolt hole 9 on the vertical purlin. The connecting bolt passes through the bolt hole and is fixed by the tightening bolt, achieving the fixed connection between the vertical purlin 2 and the clamping piece 4, thereby completing the fixed installation of the vertical purlin 2 and the supporting outer beam 1. Then, the transverse purlin 3 is hung on the vertical purlin 2 and engaged with the hook 10 by the hanging piece 5 to complete the installation of the transverse purlin 3. The installation is convenient. Finally, the curtain wall is fixedly installed on the outside of the transverse purlin 3 to complete the curtain wall installation.
