[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] The following is combined with specific Figure 1-4 A preferred embodiment of the building curtain wall keel connector and keel assembly of the present invention is described in detail.

[0030] like Figure 3 and Figure 4 As shown, a keel assembly of a preferred embodiment of the present invention includes a keel connector 2, a module steel beam 1, an adjustable fixing clamp 3 and a keel 4, wherein the keel connector 2 is built into the module steel beam 1, the keel 4 is vertically arranged on one side of the module steel beam 1, and is detachably connected via the adjustable fixing clamp 3.

[0031] Specifically, Figure 1 and Figure 2As shown, the keel assembly of this embodiment is preferably π-shaped, and includes a connecting plate 21 and a supporting side plate 22 in detail. The supporting side plate 22 of this embodiment strengthens the entire keel assembly to resist lateral bending moment. The supporting side plate 22 includes two pieces. The two supporting side plates 22 are consistent in size and shape and are located on one side of the connecting plate 21. The two ends close to the connecting plate 21 are perpendicular to the connecting plate 21. The connection method between the connecting plate 21 and the supporting side plate 22 is a fixed connection. The fixed connection here is preferably welding. Of course, it can also be other fixed connection methods, and this embodiment does not limit this.

[0032] In this embodiment, the connecting plate 21 and the supporting side plate 22 are both prefabricated in the cavity of the modular steel beam 1, wherein the supporting side plate 22 is located inside the modular steel beam 1, and the connecting plate 21 is located at the end of the modular steel beam 1, and is detachably connected to the keel 4 through an adjustable fixing clamp 3.

[0033] The method of prefabricating both the connection plate 21 and the supporting side plate 22 in the cavity of the modular steel beam 1 at the same time can also resist the deformation of the curtain wall connection device caused by the bending moment generated by the wind pressure on the modular steel beam 1.

[0034] More specifically, the connecting plate 21 has a slide groove 211, which is preferably strip-shaped and arranged along the length direction of the connecting plate 21. The slide groove 211 is used to install bolts, and the strip-shaped slide groove 211 facilitates the bolts to slide in the slide groove 211, that is, the bolts can slide left and right in the slide groove 211 and finally lock in a certain position to ensure that the left and right positions of the same vertical external keel 4 of multiple modules of the entire building are consistent.

[0035] In order to facilitate the insertion of the bolt into the slide groove 211, Figure 1 and Figure 2 As shown, an enlarged hole 2111 is provided on the slide groove 211, and the aperture of the enlarged hole 2111 is larger than the width of the slide groove 211, so as to facilitate the insertion of the bolt into the slide groove 211 from the enlarged hole 2111. In this embodiment, the slide groove 211 with the enlarged hole 2111 can not only ensure the convenience and efficiency of on-site connection, but also absorb the cumulative error during on-site module splicing.

[0036] The above-mentioned slide groove 211 for installing bolts includes at least one, and the present embodiment preferably includes two. The two slide grooves 211 are arranged in parallel and spaced a certain distance apart. The use of multiple slide grooves 211 can increase the connection strength.

[0037] In addition, in this embodiment, the side of the supporting side plate 22 away from the connecting plate 21 is chamfered, thereby reducing the weight of the entire keel connecting member 2 .

[0038] Optionally, a reinforcing plate 23 is provided between the supporting side plates 22, and both ends of the reinforcing plate 23 are fixed on the supporting side plates 22. The reinforcing plate 23 is also located between the upper and lower slideways. The reinforcing plate 23 is used to improve the overall rigidity of the building curtain wall keel connector 2 and reduce the amount of steel used.

[0039] In addition, if Figure 4 As shown, the adjustable fixing clamp 3 of this embodiment is preferably an L-shaped metal plate, which is detachably connected to the module steel beam 1 and the keel 4. The detachable connection here is preferably a bolt connection. When installed, the L-shaped metal plate is located on both sides of the vertical keel 4, thereby strengthening the fixation of the keel 4.

[0040] Detailed, such as Figure 3 As shown, the adjustable fixing fixture 3 is provided with a mounting hole 31, and the mounting hole 31 is an ellipse with a certain length. The elliptical mounting hole 31 can adjust the front and rear position of the keel 4 to ensure that the front and rear positions of the same vertical external keel 4 of multiple modules of the entire building are consistent, and can also effectively absorb the verticality and position errors of the module facade to ensure the flatness of the final curtain wall finished surface.

[0041] In this embodiment, round holes are also provided on both sides of the keel 4 , and round hole bolts penetrate through both sides of the keel 4 to achieve connection and fixation between the keel 4 and the adjustable fixing fixture 3 .

[0042] As a more preferred embodiment, Figure 3 As shown, the keel 4 of this embodiment is composed of a plurality of keel units 41, and adjacent keel units 41 are plug-connected. Specifically, the keel unit 41 is vertically connected to the plug-in component 42, and the plug-in component 42 is made of a square tube with an outer diameter slightly smaller than the inner diameter of the keel 4. A circular hole is opened at the same position as the keel unit 41. When splicing, the bolts pass through the connection, and the exposed part is inserted into another section of the keel unit 41.

[0043] After rigorous calculation of wind load on exterior walls, the keel assembly of the present invention can also meet the use requirements for coastal cities with large wind loads. The keel assembly of the present invention can not only effectively improve the installation efficiency of modular steel structure curtain walls, but also has the advantages of easy operation and recyclability. It has important practical engineering application value and has broad application prospects and market demand.
