Description

Technical Field

[0001] This utility model relates to the technical field of steel structure connection components, specifically a reinforced steel structure for energy-saving steel structure connections. Background Technology

[0002] In modern buildings and industrial facilities, energy-saving steel structure systems are widely used due to their comprehensive advantages. They employ technologies such as lightweight and high-strength steel, factory prefabrication, and rapid on-site dry construction to achieve resource conservation (energy saving, material saving, water saving, and land saving) and reduce environmental impact throughout the building's entire life cycle. The core features of these steel structure building systems are the recyclability of materials, low energy consumption during construction, and the ability of the structure itself to provide efficient support for the building envelope and energy-saving equipment.

[0003] However, the overall performance of steel structures largely depends on the reliability of their node connections. Traditional steel structure connection methods, such as welding or ordinary bolt connections, have particularly prominent limitations when applied to energy-saving steel structures: welding requires high operational skills, it is difficult to guarantee the quality of on-site construction, the high energy consumption and dust generated do not conform to the concept of green construction, and stress concentration is easily generated at the weld points; ordinary bolt connections rely on the preload of bolts, which are prone to loosening under long-term dynamic loads or extreme working conditions, resulting in a decrease in connection stiffness and affecting structural safety and durability.

[0004] In particular, for T-shaped connection nodes commonly found in energy-saving steel structures, traditional connection methods often struggle to provide stable and uniform constraint forces in multiple directions simultaneously. Some of the reinforced connectors in existing technologies are typically complex in structure and have cumbersome installation procedures, or fail to effectively address the problem of loose fit between components due to processing and installation errors, thus affecting the effective transmission of force. This restricts the potential of energy-saving steel structure systems to achieve higher safety, faster construction speed, and better overall performance.

[0005] Therefore, there is an urgent need in this field for a new type of reinforced steel structure connection solution that combines high strength, convenient installation, and the ability to adaptively eliminate installation gaps, in order to solve the above-mentioned technical problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a reinforced steel structure for the connection of energy-saving steel structures, thus solving the aforementioned problems.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a reinforced steel structure for the connection of an energy-saving steel structure, comprising a connector, a first connecting arm and a second connecting arm that are inserted into the connector, a clamping frame, and two reinforcing corner pieces symmetrically arranged on the left and right sides of the first connecting arm;

[0010] The first connecting arm has a protrusion on its outer side, the second connecting arm has a wedge-shaped block on its outer side, the inner wall of the tightening frame has a wedge-shaped groove that mates with the wedge-shaped block, the tightening frame is fitted below the connection between the connector and the two second connecting arms, the reinforcing corner piece includes an L-shaped piece, the top of the L-shaped piece has a pressing edge, and the reinforcing corner piece is located at the corner where the connector and the first connecting arm are connected;

[0011] Each of the second connecting arms is provided with wedge-shaped blocks on both the front and rear sides, and the tightening frame is provided with wedge-shaped grooves that cooperate with them, so that each of the second connecting arms can be subjected to symmetrical wedge tightening force to achieve a uniform locking effect.

[0012] When the bottom of the reinforcing corner piece is locked and fixed to the connector, the second connecting arm and the tightening frame by the second connecting arm fixing bolt, the pressing edge presses down on the protrusion, so that the first connecting arm and the connector are inserted and fixed. At the same time, the tightening frame pushes the wedge block through the wedge groove, so that the second connecting arm and the connector are inserted and fixed.

[0013] Preferably, the two reinforcing corner pieces are locked and fixed to the connecting piece and the first connecting arm by the first connecting arm fixing bolt.

[0014] Preferably, the connector is provided with a first insertion hole for engaging with the first connecting arm and a plug for engaging with the second connecting arm, and the second connecting arm is provided with a second insertion hole for accommodating the plug on the connector.

[0015] Preferably, a triangular plate is fixedly connected to the L-shaped member of the reinforcing corner piece at its included angle. The triangular plate serves as a reinforcing rib to enhance the structural strength of the L-shaped member and its reinforcement effect on the connection node between the first connecting arm and the connecting member.

[0016] Preferably, the first connecting arm fixing bolt passes through one of the reinforcing corner pieces, the first connecting arm, and another reinforcing corner piece in sequence, and locks and fixes all three to the connecting piece.

[0017] Preferably, the second connecting arm fixing bolt passes through the reinforcing corner piece, the connecting piece, the second connecting arm, and the tightening frame in sequence, and locks and fixes the four together.

[0018] Preferably, the bolt holes on both the first connecting arm and the second connecting arm are provided with sliding space;

[0019] During installation, first tighten the fixing bolts of the first connecting arm so that the two reinforcing corner pieces hug the first connecting arm and the connecting piece, and perform preliminary positioning of the reinforcing corner pieces;

[0020] Then tighten the second connecting arm fixing bolt. At this time, the clamping frame pushes the wedge block of the second connecting arm through the wedge groove, so that the second connecting arm slides relative to the second connecting arm fixing bolt with the help of the sliding space until it is fully inserted into the connector.

[0021] At the same time, the pressing edge of the reinforcing corner piece presses down on the protrusion of the first connecting arm, causing the first connecting arm to slide relative to the first connecting arm fixing bolt by means of the sliding space until it is fully inserted into the connecting piece;

[0022] After both connecting arms are fully inserted, the fixing bolts of the first connecting arm are finally tightened completely.

[0023] (III) Beneficial Effects

[0024] This utility model provides a reinforced steel structure for the connection of energy-saving steel structures. It possesses the following features:

[0025] Beneficial effects:

[0026] Through the synergistic action of the tightening frame and the reinforcing corner piece, fastening forces are applied to the second connecting arm and the first connecting arm respectively. The tightening frame, through the wedge groove and the inclined surface of the wedge block, generates a horizontal squeezing force when the bolt is tightened, pushing the second connecting arm tightly towards the connector. At the same time, the reinforcing corner piece generates a vertical squeezing force by pressing the protrusion along the downward pressing of the first connecting arm, so that the first connecting arm is tightly inserted into the connector, ensuring the stability of the node in all force directions.

[0042] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.

[0043] This embodiment provides a reinforced steel structure for the connection of energy-saving steel structures, such as... Figures 1 to 9 As shown, the reinforced steel structure mainly includes connector 1, first connecting arm 2, second connecting arm 3, clamping frame 4, reinforcing corner piece 5, first connecting arm fixing bolt 6 and second connecting arm fixing bolt 7.

[0044] The connector 1 is the central connecting hub of this structure, and it is provided with a socket 11 for inserting the first connecting arm 2 and a plug 12 for inserting the second connecting arm 3.

[0045] The upper outer side of the first connecting arm 2 is provided with a protrusion 21. The outer side of the second connecting arm 3, specifically its front and rear sides, is symmetrically provided with wedge-shaped blocks 31, and its arm body is provided with a second insertion hole 32 for accommodating the insertion block 12 on the connecting member 1.

[0046] The tightening frame 4 is a locking component, and four wedge-shaped grooves 41 are symmetrically opened on its inner wall for correspondingly engaging with the four wedge-shaped blocks 31 on the two second connecting arms 3.

[0047] Two reinforcing corner pieces 5 are provided and symmetrically arranged on the left and right sides of the first connecting arm 2. Each reinforcing corner piece 5 includes an L-shaped piece 51. A triangular plate 52, which serves as a reinforcing rib, is fixedly connected to the inner side of the included angle of the L-shaped piece 51 to significantly enhance the rigidity of the L-shaped piece 51 itself and its reinforcement effect on the connection node. The top of the L-shaped piece 51 extends inward to form a pressing edge 53.

[0048] The installation process and working principle of this utility model are as follows:

[0049] First, preliminary assembly: First, insert the first connecting arm 2 into the first insertion hole 11 of the connector 1, align the second insertion holes 32 of the two second connecting arms 3 and fit them onto the insertion block 12 of the connector 1, and then fit the tightening frame 4 from below onto the connection between the two second connecting arms 3 and the connector 1.

[0050] Second, corner piece positioning and pre-tightening: Place the two reinforcing corner pieces 5 at the left and right corners formed by the first connecting arm 2 and the connector 1 respectively. At this time, insert and pre-tighten the first connecting arm fixing bolt 6. The bolt passes through one reinforcing corner piece 5, the first connecting arm 2 (whose bolt hole has reserved sliding space), the other reinforcing corner piece 5 and is initially connected to the connector 1. The pre-tightening force makes the two reinforcing corner pieces 5 hug the first connecting arm 2 and the connector 1, realizing the initial positioning of the reinforcing corner pieces 5, preventing its lateral displacement, and laying a stable foundation for subsequent steps.

[0051] Third, core locking and automatic alignment: Next, the second connecting arm fixing bolt 7 is locked. This bolt passes through the reinforcing corner piece 5, the connecting piece 1, the second connecting arm 3 (whose bolt hole has reserved sliding space) and the tightening frame 4 in sequence. During the tightening process, the tightening frame 4 is pulled upward. The inclined surface of the wedge groove 41 on its inner side interacts with the inclined surface of the wedge block 31 on the second connecting arm 3, generating a strong horizontal component force pointing towards the connecting piece 1. This force forces the second connecting arm 3 to slide towards the connecting piece 1 using the sliding space of the bolt hole until it is completely and tightly inserted into the connecting piece 1.

[0052] At the same time, during the tightening of the second connecting arm fixing bolt 7, the reinforcing corner piece 5 is pulled down, and the pressing edge 53 at its top presses down on the protrusion 21 on the first connecting arm 2. This pressure forces the first connecting arm 2 to use the sliding space of its bolt hole to fully and tightly insert itself into the connecting piece 1.

[0053] Fourth, final fixation: After the first connecting arm 2 and the second connecting arm 3 are fully in place under the action of wedging and pressing, the first connecting arm fixing bolt 6 is finally fully locked. At this point, the entire connection node forms a stable whole with high rigidity and uniform force.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
