Description

Technical Field

[0001] This utility model relates to the field of building partition wall structure technology, and in particular to a high-strength light steel keel partition wall building material structure. Background Technology

[0002] Light steel keel, as a new type of building material, is widely used in modern construction projects for the construction of non-load-bearing partition walls due to its advantages such as light weight, high strength, convenient construction, and environmental friendliness. Typically, a light steel keel partition wall system consists of vertical keels arranged vertically and horizontal keels arranged horizontally, which interweave to form the basic framework of the wall. Subsequently, wall materials such as gypsum board are installed on both sides of the framework.

[0003] In traditional construction processes, the connection between vertical and horizontal joists, as well as the fixing of various connectors, mainly relies on self-tapping screws for fastening. While this screw-based connection method is simple to operate, its structural limitations are becoming increasingly apparent. Screw connections are essentially point connections, and their tightening force depends entirely on the thread engagement force and the local bearing capacity of the sheet metal, resulting in relatively concentrated stress at the connection point.

[0004] Over time, factors such as building settlement, vibrations from opening and closing doors and windows during daily use, and thermal expansion and contraction of materials will continuously act on these connection nodes. Under these long-term, repeated loads, screws may loosen, causing small gaps in the fit at the connection nodes, which in turn reduces the overall integrity and rigidity of the entire wall frame. Insufficient strength of the connection nodes has become a key bottleneck restricting the overall structural strength and durability of traditional light steel keel partition walls.

[0005] Once the reliability of the node connection decreases, the wall is prone to shaking and deformation when subjected to external impact or lateral thrust. This can also lead to cracks at the joints of the plasterboard on the wall surface, seriously affecting the aesthetics and service life of the wall and failing to meet the requirements of modern buildings for high-quality and high-stability partition wall structures.

[0006] Therefore, this utility model proposes a high-strength light steel keel partition wall building material structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology, the joint connection of light steel keel partition wall building material structure mainly relies on screws, which has low connection strength and will loosen under long-term vibration or load, resulting in the instability of the overall wall structure and easy cracking of the wall surface. This utility model aims to provide a high-strength light steel keel partition wall building material structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a high-strength light steel keel partition wall building material structure, including: vertical keel; horizontal keel intersecting the top of the vertical keel in a T-shape; and an intermediate frame housed in the top opening of the vertical keel and used to connect the vertical keel and the horizontal keel simultaneously; it also includes a node mechanism for achieving high-strength connection and bolts for final fastening.

[0009] The node mechanism is the key to realizing the function of this solution. It includes a connecting block that is fixedly connected to the inner wall of the vertical keel. The connecting block has a cavity for the intermediate frame to be inserted, and it is integrally provided with a slot and a hook.

[0010] Furthermore, the intermediate frame, connecting block, and other components of the node mechanism are combined in the following way: the intermediate frame is elastically provided with buckles that can be plugged into the slots on the connecting block for initial positioning during installation. The intermediate frame is also rotatably pivotally connected to a rotating shaft, with a button fixedly connected to the outer end of the rotating shaft for user operation. One end of a connecting rod is eccentrically fixedly connected to the rotating shaft. In the assembled state, when the button is lifted upward, it drives the rotating shaft to rotate, and through the eccentrically connected connecting rod, the other free end of the connecting rod moves upward and engages with the hook. Through the lever principle, the intermediate frame is pulled towards the connecting block, forming a high-strength reinforced locking. Finally, after the wall panel is installed, the bolts pass through the wall panel and the intermediate frame in sequence and are threaded onto the connecting block, completing the final structural reinforcement.

[0011] Preferably, the top of the intermediate frame is integrally formed with a U-shaped support groove for supporting and fixing the horizontal keel. The inner contour of the U-shaped support groove is adapted to the bottom contour of the horizontal keel. This design not only provides a stable and large contact area for the horizontal keel, but also facilitates quick fixing by screws or other means, ensuring the verticality and stability of the connection between the vertical and horizontal keels.

[0012] Preferably, the buckle is constructed as an elastic arm formed by integral stamping from the side wall of the intermediate frame and bending outward. This integral stamping structure requires no additional components, simplifies the production process, and ensures that the buckle has reliable and durable elasticity. The free end of the buckle also has a guiding slope. The slope design allows the intermediate frame to slide smoothly into the connecting block during installation and guides the buckle to automatically compress and finally pop into the slot accurately, realizing tool-free rapid pre-installation.

[0013] Preferably, the shape of the press block is set to an ergonomic wrench shape, and its surface is provided with anti-slip texture. This design fully considers the ease of operation in actual construction. The wrench shape provides the construction personnel with a good lever arm, enabling them to easily apply sufficient torque, while the anti-slip texture increases friction and prevents slipping during operation, ensuring that the enhanced locking step can be completed efficiently and safely.

[0014] Preferably, the high-strength light steel keel partition wall building material structure also includes an auxiliary support mechanism. The auxiliary support mechanism includes an auxiliary frame welded and fixed to the top surface of the horizontal keel, and a diagonal brace with one end connected to the auxiliary frame and the other end abutting against the side wall of the vertical keel. The introduction of the diagonal brace divides the original rectangular frame into multiple stable triangular units, fundamentally improving the ability of the entire wall frame to resist lateral thrust and shear deformation from a structural mechanics perspective.

[0015] Preferably, in order to reliably fix the diagonal brace in the above-mentioned auxiliary support mechanism, the auxiliary frame is provided with a fixing groove extending in the vertical direction, and the end of the diagonal brace is provided with a fixing groove that matches the fixing groove one, and includes a fixing block as a pin. During installation, it is only necessary to align the two grooves and insert the fixing block into them to lock the diagonal brace. This pin-type connection method is simple and quick, and the fixing effect is reliable.

[0016] Preferably, the cavity of the wall formed by the vertical keel, the horizontal keel and the adjacent vertical keel is filled with honeycomb sponge. As a lightweight filling material, honeycomb sponge can not only significantly improve the sound insulation and heat insulation performance of the wall and create a more comfortable indoor environment, but it also provides uniform back support for the wall panel, effectively improving the impact resistance of the wall and avoiding the hollow feeling that is easy to occur in traditional hollow walls.

[0017] Preferably, the connecting block is a block structure adapted to the shape of the inner cavity of the vertical keel, and has threaded holes pre-set on it for fastening the bolts. The shape of the connecting block fits tightly with the inner cavity of the vertical keel, increasing the contact area and ensuring its installation stability inside the vertical keel, providing a solid foundation for the entire node mechanism. The pre-set threaded holes ensure that the final reinforcing bolts can be firmly tightened.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting a preliminary positioning mechanism composed of buckles and slots, and a lever-type enhanced locking mechanism composed of blocks, rotating shafts, connecting rods and hooks working together, forms a double-locking node structure, which solves the problem that the existing light steel keel mainly relies on screw connection, resulting in low node strength, easy loosening, and unstable wall connection. It achieves extremely firm node connection, high reliability, and effective resistance to vibration and pull-out.

[0019] 2. This utility model solves the problem that traditional light steel keel wall frames are rectangular structures with poor overall stability and are prone to shear deformation under external forces, leading to wall cracking, by adding diagonal braces between the vertical and horizontal keels and using auxiliary frames, fixing grooves and fixing blocks to fix the diagonal braces. It achieves the goal of dividing the wall frame into multiple stable triangular structures, thereby greatly improving the rigidity and deformation resistance of the entire wall structure.

[0020] 3. This utility model solves the problem that existing light steel keel partition walls have poor sound and heat insulation performance due to the cavity inside, and are prone to hollowness or damage when the wall surface is impacted by filling the cavity with honeycomb sponge. It achieves a significant improvement in the sound and heat insulation effect of the wall, while providing effective support for the wall panel and improving the impact resistance of the wall surface.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0024] Please refer to Figures 1 to 4 This utility model provides a high-strength light steel keel partition wall building material structure, which aims to solve the problems of insufficient reliability of node connection and easy deformation of the frame in the existing light steel keel partition wall structure.

[0025] like Figure 1 and Figure 2As shown, a high-strength light steel keel partition wall building material structure includes vertical keels 201, horizontal keels 202 intersecting the top of the vertical keels 201 in a T-shape, and an intermediate frame 1 housed in the top opening of the vertical keels 201 and used to connect the vertical keels 201 and the horizontal keels 202 simultaneously. The structure is reinforced by a node mechanism 2, which includes a connecting block 203 fixedly connected to the inner wall of the vertical keel 201. The connecting block 203 has a cavity for the intermediate frame 1 to be inserted into, and a slot 205 and a hook 206 integrally formed on the connecting block 203. The intermediate frame 1 is elastically provided with a hook that engages with the slot. The 205 is a snap-fit ​​buckle 204. The intermediate frame 1 is also rotatably pivotally connected to a rotating shaft 208. The outer end of the rotating shaft 208 is fixedly connected to a button 209 for user operation. One end of a connecting rod 210 is eccentrically fixedly connected to the rotating shaft 208. The other free end of the connecting rod 210 is configured such that when the button 209 is lifted upward, the free end of the connecting rod 210 can move upward and engage with the inside of the hook 206, thereby pulling the intermediate frame 1 towards the connecting block 203. The structure also includes a bolt 207. After the wall panel is installed, the bolt 207 passes through the wall panel and the intermediate frame 1 in sequence and is threadedly fastened to the connecting block 203.

[0026] Please refer to Figure 3 The connecting block 203 is a block structure adapted to the shape of the inner cavity of the vertical keel 201. It has threaded holes for fastening bolts 207. The connecting block 203 is fixedly connected to the inner wall of the vertical keel 201 by welding or riveting. The slot 205 is a recess. The hook 206 is a hook-shaped body that extends upward from the surface of the connecting block 203 and bends towards the intermediate frame 1. Meanwhile, a buckle 204 is correspondingly provided on the intermediate frame 1. The buckle 204 is an elastic arm formed by integrally stamping from the side wall of the intermediate frame 1 and bending outward. The free end of the buckle 204 has a guide slope. During installation, the intermediate frame 1 is inserted into the cavity of the connecting block 203. The guide slope of the buckle 204 first contacts the edge of the connecting block 203 and is pressed back. When it moves to the position of the slot 205, it springs into the slot 205 under its own elasticity, thus achieving a preliminary and quick fixation to prevent the intermediate frame 1 from falling out. The button 209 is ergonomically designed like a wrench and has anti-slip texture. The button 209 is coaxially fixed to the outer end of the rotating shaft 208 via a key connection, ensuring that rotating the button 209 can synchronously drive the rotating shaft 208 to rotate. The rotating shaft 208 is rotatably mounted on the intermediate frame 1 via bearings or bushings. One end of the connecting rod 210 is pivotally connected to the eccentric position of the rotating shaft 208 via a pin. When the button 209 is lifted upward, the rotating shaft 208 rotates, and its eccentric point drives the connecting rod 210 to move upward. Finally, the free end of the connecting rod 210 passes over and engages with the inner side of the hook 206, forming a tight lock using the lever principle. This double locking structure of buckle 204 and lever ensures a very high-strength connection between the intermediate frame 1 and the vertical keel 201, effectively resisting tension and vibration in various directions.

[0027] In a preferred embodiment, in order to achieve a stable connection between the intermediate frame 1 and the horizontal keel 202, the top of the intermediate frame 1 is integrally formed with a U-shaped support groove for supporting and fixing the horizontal keel 202. The bottom contour of the horizontal keel 202 is adapted to the U-shaped support groove. After the horizontal keel 202 is placed in the U-shaped support groove, it can be fixedly connected to the side wall of the U-shaped support groove by self-tapping screws or rivets.

[0028] As another preferred embodiment, to further enhance the structural stability of the entire wall frame, the structure also includes an auxiliary support mechanism 3, please refer to... Figure 4 The auxiliary support mechanism 3 includes an auxiliary frame 301 welded and fixed to the top surface of the horizontal keel 202, and a diagonal brace 304 connected at one end to the auxiliary frame 301 and at the other end abutting against the side wall of the vertical keel 201. The diagonal brace 304 forms a stable triangular structure between the vertical keel 201 and the horizontal keel 202.

[0029] In the structure of the above-mentioned auxiliary support mechanism 3, in order to achieve convenient installation and reliable fixation of the diagonal brace 304, the auxiliary frame 301 is provided with a fixing groove 302 extending in the vertical direction, and the end of the diagonal brace 304 is provided with a fixing groove 303 that is adapted to the fixing groove 302. The auxiliary support mechanism 3 also includes a fixing block 305 as a pin. During installation, the diagonal brace 304 is placed in place, and after the fixing groove 302 and the fixing groove 303 are aligned, the fixing block 305 is inserted into the aligned groove to complete the fixation of the diagonal brace 304.

[0030] In another preferred embodiment, in order to improve the sound insulation and heat insulation performance of the wall and increase the impact resistance of the wall surface, honeycomb sponge 306 is filled in the cavity of the wall formed by the vertical keel 201, the horizontal keel 202 and the adjacent vertical keel 201.

[0031] Working principle: When installing the wall frame, first fix the vertical keel 201 to the ground and ceiling according to the design position, then insert the intermediate frame 1 into the top opening of the vertical keel 201, so that it enters the cavity of the connecting block 203. During the insertion process, the buckle 204 on the intermediate frame 1 is compressed inward due to the action of its guiding slope. After passing a specific position, the buckle 204 springs into the slot 205 of the connecting block 203 under the action of its own elastic restoring force, so as to achieve the initial quick fixation of the intermediate frame 1 and prevent it from accidentally slipping out. After initial fixing, lift the push block 209 located outside the intermediate frame 1 upwards. The push block 209 drives the eccentrically set connecting rod 210 to move through the rotating shaft 208. The free end of the connecting rod 210 moves upwards and finally gets into the inside of the hook 206 on the connecting block 203. Since the connecting rod 210 is locked by the eccentric lever principle, this action will generate a strong tension force on the intermediate frame 1 towards the connecting block 203, thereby eliminating all potential gaps between the intermediate frame 1 and the connecting block 203 (i.e., the vertical keel 201) and forming an extremely strong secondary reinforcement locking. Then, place the horizontal keel 202 in the U-shaped bearing groove at the top of the intermediate frame 1 and fix it. At this point, the high-strength keel connection node is completed. After the wall frame is erected, auxiliary support and filling are carried out. The auxiliary frame 301 is welded to the top surface of the horizontal keel 202. Then, the diagonal brace 304 is placed in the gap between the keels, with one end abutting against the vertical keel 201 and the other end aligned with the auxiliary frame 301. The fixing block 305 is inserted into the aligned fixing groove 1 302 and fixing groove 2 303 to complete the installation of the diagonal brace 304, providing the wall frame with resistance to shear deformation. Finally, the honeycomb sponge 306 is filled into the cavity formed by the keel, and the wall panel is installed on the outer surface of the wall. The bolts 207 are tightened so that they pass through the wall panel and the intermediate frame 1, and finally screwed into the preset threaded hole of the connecting block 203 to complete the final reinforcement.
