Description

Technical Field

[0001] This invention mainly relates to the field of building engineering, and in particular to a horizontal keel vertical plug-in type rear-mounted keel frame. Background Technology

[0002] Curtain walls generally include steel curtain walls and aluminum curtain walls. Aluminum curtain walls are easy to form and manufacture, but they do not have fire resistance. Existing steel curtain walls consist of steel keel, steel pressure plate, glass panels, and bolts. The glass panels are connected to the steel keel through the steel pressure plate and bolts. Sealant is applied between the glass panels and the steel keel and steel pressure plate to ensure sealing performance and connection strength.

[0003] In existing technologies, during the construction of keel frame systems, vertical and horizontal keels are usually erected and connected sequentially from one side to the other, forming a vertical-horizontal-vertical construction sequence. This method of keel frame construction is complicated and has extremely high labor costs. In addition, the overall construction quality is not high, and multiple rework adjustments are required on site, which reduces installation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a horizontal keel vertical plug-in rear-mounted keel frame that is low in cost, easy to install, has high connection strength, and can improve installation quality and efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A keel frame with horizontal keel and vertical insertion and rotation type for post-installation includes multiple vertical keels, multiple horizontal keels, and multiple vertical connectors. The vertical keels are installed sequentially on the main body of the building at intervals, and locking devices are pre-installed on the vertical keels. Each vertical connector is fixed to both ends of the corresponding horizontal keel. The vertical connectors at both ends of each horizontal keel are inserted into the locking devices at the corresponding ends in the vertical direction, and after rotating around the locking devices, they form anti-reverse constraints in the horizontal and vertical directions. When the locking devices are tightened, the locking devices drive the vertical connectors to form a locking and fixation with the vertical keels.

[0007] As a further improvement to the above technical solution:

[0008] The horizontal keel is provided with a recessed groove, and the vertical connector cooperates with the recessed groove to form a constraint limit.

[0009] The horizontal keel has an operating hole for inserting a tool to tighten the locking component.

[0010] The vertical connector includes a connector plate with fitting plates bent at both ends and a pair of clamping plates bent on the connector plate. The vertical connector is connected to the horizontal keel end through the fitting plates. The connector plate is inserted into the locking member at the corresponding end in the vertical direction and rotates around the locking member to form anti-reverse constraints in the horizontal and vertical directions. When the locking member is tightened, the locking member drives the connector plate to lock and fix with the vertical keel.

[0011] The sleeve plate is connected to the horizontal keel by screws.

[0012] The plug-in plate has a vertical slot and an arc-shaped groove. The openings of the vertical slot and the arc-shaped groove are parallel to the openings of the countersunk groove. The locking element is a pair of bolts. The vertical slot and the arc-shaped groove are plugged into the corresponding bolts. After rotating 90° around the bolts, the arc-shaped groove is plugged into the bolts to form a backstop constraint. When the bolts are tightened, the bolt head drives the vertical plug-in element to lock and fix it to the vertical keel.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] The present invention relates to a horizontal keel vertical insertion and rotation type rear-mounted keel frame, which includes multiple vertical keels, multiple horizontal keels, and multiple vertical insertion components. Each vertical keel is installed sequentially on the building body at intervals, and each vertical keel is pre-installed with a locking component. Each vertical insertion component is fixed to both ends of the corresponding horizontal keel. The vertical insertion components at both ends of each horizontal keel are inserted into the corresponding locking components in the vertical direction, and after rotating around the locking components, they form anti-reverse constraints in the horizontal and vertical directions. When the locking components are tightened, the locking components drive the vertical insertion components to form a locking and fixation with the vertical keels. During installation, the locking components are first pre-installed onto each vertical keel, and each vertical connector is fixed to both ends of the corresponding horizontal keel. Then, the vertical keels are installed sequentially at intervals on the building structure. Next, the vertical connectors at both ends of each horizontal keel are simultaneously inserted into the corresponding locking components from a vertical direction. Using the locking component as the center, the vertical connectors are rotated to create a horizontal and vertical anti-reverse constraint. Finally, the locking components are tightened to lock the vertical connectors to the vertical keels. Compared to traditional methods, this keel frame simplifies the installation process and reduces the difficulty and cost by pre-installing the locking components and vertical connectors onto the vertical and horizontal keels, allowing for the subsequent installation of the horizontal keels. Furthermore, the method of erecting the vertical keels first and then installing the horizontal keels improves the overall installation quality, eliminates the need for multiple rework adjustments, and increases installation efficiency. The anti-reverse constraint created by inserting and then rotating enhances the connection strength. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Figs. 1 to 4 This invention illustrates an embodiment of a keel frame with a horizontal keel and a vertical insertion-type rear-mounted design. The keel frame includes multiple vertical keels 1, multiple horizontal keels 2, and multiple vertical connectors 3. Each vertical keel 1 is installed sequentially on the building body at intervals, and each vertical keel 1 is pre-installed with a locking member 4. Each vertical connector 3 is fixedly installed at both ends of the corresponding horizontal keel 2. The vertical connectors 3 at both ends of each horizontal keel 2 are inserted vertically into the corresponding locking member 4 and rotated around the locking member 4 to form a locking constraint in both the horizontal and vertical directions. When the locking member 4 is tightened, the locking member 4 drives the vertical connector 3 to lock and fix with the vertical keel 1. During installation, first, pre-install the locking parts 4 onto each vertical keel 1, then fix each vertical connector 3 to both ends of the corresponding horizontal keel 2. Next, install each vertical keel 1 on the main building at intervals. Then, insert the vertical connectors 3 at both ends of each horizontal keel 2 into the corresponding locking parts 4 from the vertical direction. Then, with the locking parts 4 as the center, rotate the vertical connectors 3 to form a horizontal and vertical anti-reverse constraint with the locking parts 4. Finally, tighten the locking parts 4 to lock the vertical connectors 3 and the vertical keel 1. Compared to traditional methods, this keel frame simplifies the installation process and reduces the difficulty by pre-installing the locking parts 4 and vertical connectors 3 onto the vertical keels 1 and horizontal keels 2, allowing the horizontal keels 2 to be installed later. This also reduces costs. Furthermore, the method of assembling the vertical keels 1 first and then installing the horizontal keels 2 later improves the overall installation quality, eliminates the need for multiple rework adjustments, and increases installation efficiency. The use of insertion followed by rotation to create a backstop constraint also enhances the connection strength.

[0023] In this embodiment, a recessed groove 21 is provided on the horizontal keel 2, and the vertical connector 3 cooperates with the recessed groove 21 to form a constraint limit. In this structure, the vertical connector 3 is connected to the locking member 4 on the one hand, and on the other hand, the vertical connector 3 cooperates with the recessed groove 21 to form a constraint limit, which has a strengthening effect, making the connection between the horizontal keel 2 and the vertical connector 3 more stable and reliable.

[0024] In this embodiment, the horizontal keel 2 is provided with an operating hole 22 for inserting a tool to tighten the locking member 4. When the horizontal keel 2 is installed later, the operating hole 22 allows a tool to be inserted to tighten the locking member 4 to complete the final locking. Its structure is simple and ingenious.

[0025] In this embodiment, the vertical connector 3 includes a connector plate 31 with fitting plates 32 bent at both ends. A pair of clamping plates 33 are also bent on the connector plate 31. The vertical connector 3 is fitted to the port of the horizontal keel 2 via the fitting plates 32. The connector plate 31 is inserted vertically into the corresponding locking member 4 and rotates around the locking member 4 to form a locking constraint in both the horizontal and vertical directions. When the locking member 4 is tightened, it locks the connector plate 31 to the vertical keel 1. In this structure, the contour formed between the two fitting plates 32 matches the port of the horizontal keel 2, forming a mutually fitted positioning. The connector plate 31 is inserted horizontally into the corresponding locking member 4 and rotates around the locking member 4 to form a locking constraint in both the horizontal and vertical directions. At this time, the pair of clamping plates 33 clamp the outer wall of the sink 21, resulting in a simple and ingenious structure.

[0026] In this embodiment, the sleeve plate 32 is connected to the horizontal keel 2 by screws, which further improves the connection strength.

[0027] In this embodiment, the plug-in plate 31 is provided with a vertical slot 311 and an arc-shaped groove 312. The openings of the vertical slot 311 and the arc-shaped groove 312 are parallel to the opening of the countersunk groove 21. The locking member 4 is a pair of bolts. The vertical slot 311 and the arc-shaped groove 312 are plugged into the corresponding bolts, and after rotating 90° around the bolts, the arc-shaped groove 312 is plugged into the bolts to form a backlash constraint. When the bolts are tightened, the bolt head drives the vertical plug-in member 3 to lock and fix the vertical keel 1. In this structure, the vertical slot 311 and the arc-shaped groove 312 are simultaneously plugged into the corresponding bolts vertically, and after rotating 90° around the bolts, the arc-shaped groove 312 is plugged into another bolt to form a backlash constraint. The structure is simple and ingenious. Furthermore, the openings of the vertical slot 311 and the arc-shaped groove 312 are parallel to the opening of the countersunk groove 21, so that the bolts are covered by the vertical pipe wall of the horizontal keel 2, achieving a bolt concealment effect in the vertical direction.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
