In the existing metal curtain wall mounting structure, most of metal wall plates adopt a frame type mounting structure, specifically, aluminum corner brackets are fixedly mounted on the peripheral folds of the metal wall plates through rivets, and then the aluminum corner brackets on the four peripheral folds are fixedly connected with aluminum alloy keels mounted on site in advance through screws. In the installation, every aluminium angle sign indicating number on the four week folded edges of metal wallboard all is fixed with aluminum alloy fossil fragments through the screw, and its installation is loaded down with trivial details, leads to the installation effectiveness lower.

And, in the fixed point department of wallboard and aluminium angle sign indicating number, because aluminium alloy skeleton and the fixed fastening bolt's of aluminium angle sign indicating number elasticity degree are different for after wallboard and aluminium alloy skeleton are fixed, the face of two adjacent wallboards is difficult to control on the coplanar.

In view of this, the present utility model proposes a curtain wall structure.

In one embodiment of the present utility model, as shown in fig. 1 to 8, the curtain wall structure includes:

the mounting frame 10 comprises a plurality of transverse keels 11 which are arranged at intervals along the height direction and a plurality of longitudinal keels 13 which are arranged at intervals along the width direction, wherein the longitudinal keels 13 are used for being mounted and fixed with a wall body, and the transverse keels 11 are sequentially provided with a first clamping groove 121 and a second clamping groove 122 in the direction from top to bottom; and

the side bracket 30 is arranged at the side edge flanging of the wallboard 20, the side bracket 30 comprises a transverse clamping hook group 31, and the transverse clamping hook group 31 comprises an upper clamping hook 311 and a lower clamping hook 312 which are respectively arranged at the upper side and the lower side of the wallboard 20; one lateral hook group 31 is correspondingly connected with two adjacent lateral keels 11, in the same lateral hook group 31, the upper side hook 311 is hooked in the second clamping groove 122 of the upper lateral keel 11, and the lower side hook 312 is hooked in the first clamping groove 121 of the lower lateral keel 11.

Referring to fig. 1 to 3, according to the present utility model, the first clamping groove 121 and the second clamping groove 122 sequentially arranged in the vertical direction of the transverse keel 11, and the upper clamping hooks 311 and the lower clamping hooks 312 arranged on the upper side and the lower side of the wall board 20, when the wall board 20 is installed on the installation frame 10, only the upper clamping hooks 311 of the wall board 20 need to be hung on the second clamping grooves 122 of a cross beam, and the lower clamping hooks need to be hung on the first clamping grooves 121 of the lower transverse keel 11, so that the installation rate of the curtain wall is greatly improved. Meanwhile, the condition that the plate surfaces of adjacent wallboards 20 are not on the same installation plane due to uneven stress of the wallboards 20 caused by the installation mode that the fastening screw is fixed with the installation frame 10 is avoided. Which can be quickly replaced when the surface of wall panel 20 is damaged. And the number of the used screws can be reduced, and the production cost is reduced.

Referring to fig. 5 to 7, alternatively, the upper hook 311 includes a first plate portion 311a disposed at a side edge of the wall plate 20, a second plate portion 311b intersecting the first plate portion 311a and disposed at an upper side of the first plate portion 311a, and a first limit rib 311d disposed at a lower side of the first plate portion 311a, wherein the first limit rib 311d is disposed in the second slot 122, and when the second plate portion 311b abuts against one slot sidewall of the second slot 122, an adjustment gap 311e is formed between the first limit rib 311d and the other slot sidewall of the second slot 122. In the process of fixing the wall plate 20 and the side bracket 30 by the installer, a screw or rivet fixing mode is generally adopted, and because the stress applied when different installers nailing is different, the height of the wall plate 20 relative to the side bracket 30 is inconsistent, and therefore, after the wall plate 20 and the mounting frame 10 are fixed, the plate surfaces of two adjacent wall plates 20 are difficult to control on the same plane. In this application first spacing muscle 311d can remove along the thickness direction of wallboard 20 on second draw-in groove 122 for adjust interval 311 e's size and change, and then realize fine setting face position, make adjacent wallboard 20 on the coplanar, improved impression quality, building effect.

Further alternatively, the first spacing ribs 311d and the second plate portion 311b are disposed alternately on the first plate portion 311a, that is, when the second plate portion 311b abuts against a groove side wall of the second clamping groove 122, the first spacing ribs 311d are located at an intermediate section of the second clamping groove 122 in the thickness direction of the wall plate 20. Since only the upper hook 311 moves in the thickness direction of the wall plate 20 on the mounting frame 10 in this embodiment, when the first stopper rib 311d moves in the thickness direction of the wall plate 20, the wall plate 20 rotates around the axis of the lower hook 312. When the second plate portion 311b abuts against a groove sidewall of the second clamping groove 122, the first limiting rib 311d is located at the initial moving position; when the first limiting rib 311d abuts against the other groove side wall of the second clamping groove 122, the first limiting rib 311d is located at the moving limit position. In this embodiment, when the first limiting rib 311d is located at the limit position, the first limiting rib 311d abuts against the groove sidewall of the second clamping groove 122, so that the wall board 20 cannot fall over and separate from the mounting frame 10.
