Description

Technical Field

[0001] This invention mainly relates to the field of building engineering, and in particular to a horizontal keel frame with a transverse insertion and rotation mechanism. 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 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 a horizontal insertion and rotation type for post-installation includes multiple vertical keels, multiple horizontal keels, and multiple horizontal connectors. The vertical keels are installed sequentially on the building body at intervals, and locking devices are pre-installed on the vertical keels. Each horizontal connector is fixed to both ends of the corresponding horizontal keel. The horizontal connectors at both ends of each horizontal keel are inserted into the corresponding locking devices in the horizontal direction and rotate around the locking devices to form anti-reverse constraints in the horizontal and vertical directions. When the locking devices are tightened, the locking devices drive the horizontal connectors to lock and fix them to 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 horizontal 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 transverse connector includes a connector plate with fitting plates bent at both ends and a countersunk plate bent on one side. The transverse connector is sleeved with the transverse keel end through the fitting plates. The countersunk plate is inserted into the countersunk groove. The connector plate is inserted into the locking member at the corresponding end in the horizontal direction and rotates around the locking member to form a locking constraint 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 plug-in plate has a horizontal slot and an arc-shaped groove. The surface where the slot and the groove are located is perpendicular to the surface where the groove is located. The locking member is a pair of bolts. The horizontal slot is inserted into one of the bolts and rotates 90° around the bolt. Its arc-shaped groove is inserted into the other bolt to form a backstop constraint. When the bolt is tightened, the bolt head drives the horizontal plug-in member to lock and fix it to the vertical keel.

[0012] A connecting plate is also bent on one side of the plug-in plate, and the connecting plate is connected to the horizontal keel by screws.

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

[0014] The present invention relates to a transversely insertable rear-mounted keel frame, which includes multiple vertical keels, multiple horizontal keels, and multiple transverse connectors. Each vertical keel is installed sequentially on the building body at intervals, and each vertical keel is pre-installed with a locking device. Each transverse connector is fixed to both ends of the corresponding horizontal keel. The transverse connectors at both ends of each horizontal keel are inserted into the corresponding locking devices in the horizontal 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 transverse connectors to form a locking and fixation with the vertical keels. During installation, the locking components are first pre-installed onto each vertical keel, and the horizontal connectors are fixed to both ends of the corresponding horizontal keels. Then, the vertical keels are installed sequentially at intervals on the building structure. Next, the horizontal connectors at both ends of each horizontal keel are simultaneously inserted into the corresponding locking components from a horizontal direction. Using the locking components as the center, the horizontal connectors are rotated to create a horizontal and vertical anti-reverse constraint. Finally, the locking components are tightened to lock the horizontal connectors to the vertical keels. Compared to traditional methods, this keel frame, by pre-installing the locking components and horizontal connectors onto the vertical and horizontal keels, allows for the subsequent installation of the horizontal keels, greatly simplifying the installation process and reducing the difficulty, thus lowering costs. Furthermore, the method of first erecting the vertical keels 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] Figures 1 to 4 This invention illustrates an embodiment of a transversely inserted and remounted keel frame, comprising multiple vertical keels 1, multiple horizontal keels 2, and multiple transverse connectors 3. Each vertical keel 1 is sequentially installed on the building body at intervals, and each vertical keel 1 is pre-installed with a locking member 4. Each transverse connector 3 is fixedly installed at both ends of the corresponding horizontal keel 2. The transverse connectors 3 at both ends of each horizontal keel 2 are inserted into the corresponding locking member 4 in a horizontal direction, and after rotating around the locking member 4, they form a locking constraint in both the horizontal and vertical directions. When the locking member 4 is tightened, the locking member 4 drives the transverse connector 3 to lock and fix with the vertical keel 1. During installation, the locking components 4 are pre-installed onto each vertical keel 1, and each horizontal connector 3 is fixed to both ends of the corresponding horizontal keel 2. Then, the vertical keels 1 are installed sequentially at intervals on the building structure. Next, the horizontal connectors 3 at both ends of each horizontal keel 2 are simultaneously inserted into the corresponding locking components 4 in a horizontal direction. Using the locking component 4 as the center, the horizontal connectors 3 are rotated to form a locking constraint in both the horizontal and vertical directions. Finally, the locking component 4 is tightened to lock the horizontal connectors 3 to the vertical keel 1. Compared to traditional methods, this keel frame, by pre-installing the locking components 4 and horizontal connectors 3 onto the vertical keels 1 and horizontal keels 2, allows for the subsequent installation of the horizontal keels 2, greatly simplifying the installation steps and reducing the difficulty, thus lowering costs. Furthermore, the method of first installing the vertical keels 1 and then installing the horizontal keels 2 improves the overall installation quality, eliminates the need for multiple rework adjustments, and increases installation efficiency. The use of insertion followed by rotation to form a locking constraint also improves the connection strength.

[0023] In this embodiment, a recessed groove 21 is provided on the horizontal keel 2, and the transverse connector 3 cooperates with the recessed groove 21 to form a constraint limit. In this structure, the transverse connector 3 is connected to the locking member 4 on the one hand, and on the other hand, the transverse 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 transverse 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 transverse connector 3 includes a connector plate 31 with fitting plates 32 bent at both ends and a recessed platform 33 bent on one side. The transverse connector 3 is fitted to the port of the transverse keel 2 through the fitting plates 32. The recessed platform 33 is engaged with the recessed groove 21. The connector plate 31 is inserted into the locking member 4 at the corresponding end in the horizontal direction and rotates around the locking member 4 to form a locking constraint in the horizontal and vertical directions. When the locking member 4 is tightened, the locking member 4 drives the connector plate 31 to lock and fix with the vertical keel 1. In this structure, the contour formed between the two fitting plates 32 is adapted to the port of the transverse keel 2, forming a mutual fitting and positioning. The connector plate 31 is inserted into the locking member 4 at the corresponding end in the horizontal direction and rotates around the locking member 4 to form a locking constraint in the horizontal and vertical directions. At this time, the recessed platform 33 is engaged with the recessed groove 21. Its structure is simple and ingenious.

[0026] In this embodiment, the plug-in plate 31 is provided with a horizontal slot 311 and an arc-shaped groove 312. The surfaces where the openings of the horizontal slot 311 and the arc-shaped groove 312 are located are perpendicular to the surface where the countersunk groove 21 is located. The locking member 4 is set as a pair of bolts. The horizontal slot 311 is inserted into one of the bolts, and after rotating 90° around the bolt, its arc-shaped groove 312 is inserted into the other bolt to form a backlash constraint. When the bolt is tightened, the bolt head drives the horizontal plug-in member 3 to lock and fix it to the vertical keel 1. In this structure, the horizontal slot 311 and the arc-shaped groove 312 are simultaneously inserted into the corresponding bolts horizontally, and after rotating 90° around the bolt, its arc-shaped groove 312 is inserted into the other bolt to form a backlash constraint. Its structure is simple and ingenious. Furthermore, the surfaces where the openings of the horizontal slot 311 and the arc-shaped groove 312 are located are perpendicular to the surface where the countersunk groove 21 is located, so that the bolts are covered by the pipe wall in the horizontal direction of the horizontal keel 2, achieving the effect of concealing the bolts in the horizontal direction.

[0027] In this embodiment, a connecting plate 34 is also bent on one side of the plug-in plate 31, and the connecting plate 34 is connected to the horizontal keel 2 by screws. Connecting the connecting plate 34 and the horizontal keel 2 by screws further improves the connection strength.

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.
