Description

Technical Field

[0001] This utility model relates to the field of flexible connection technology, specifically to a flexible connection structure for explosion-proof walls. Background Technology

[0002] Flexible connection structures play a crucial role in the design and construction of blast walls. They connect the blast wall structure to the main frame beams while simultaneously preventing excessive reaction forces on the main frame caused by the deformation of the blast wall under blast impact. This connection method allows the blast wall to deform to a certain extent upon impact, thereby absorbing and dispersing blast energy and reducing the damage of the shock wave to the protected area. The flexible connection structure typically consists of two parts: a panel beam and a web beam. The panel beams are connected to rigid angle steel, while the web beams are connected to the I-beams of the main frame.

[0003] The connection parts of the existing flexible connection structure are rigid, which is insufficient to resist deformation under stress. Under the impact of an explosion, the connection parts are not efficient at absorbing the energy of the explosion, which can easily lead to large displacement of the blast wall, resulting in a decrease in the overall stability of the structure, reducing the effectiveness of the flexible connection structure and failing to meet the application requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible connection structure for blast-resistant walls, in order to solve the problems mentioned in the background art, where the connection parts of existing flexible connection structures are rigid, which have insufficient resistance to deformation under stress. Under explosive impact, the connection parts have poor efficiency in absorbing explosive impact energy, which can easily lead to large displacement of the blast-resistant wall, resulting in a decrease in the overall stability of the structure, reducing the effectiveness of the flexible connection structure, and failing to meet the usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible connection structure for an blast-resistant wall, comprising a connecting body, a main frame beam, and an blast-resistant wall. A flexible angle steel is provided on one side of the connecting body, and the flexible angle steel is welded integrally with the connecting body. A pre-fabricated perforated right-angle galvanized connector is provided on the other side of the connecting body, and the pre-fabricated perforated right-angle galvanized connector is welded integrally with the connecting body. A first channel steel beam is provided at the rear end of the blast-resistant wall, and a first expansion bolt is provided between the first channel steel beam and the blast-resistant wall, and the first channel steel beam and the blast-resistant wall are fixedly connected by the first expansion bolt. A second channel steel beam is provided at the front end of the main frame beam, and a second expansion bolt is provided between the second channel steel beam and the main frame beam, and the second channel steel beam and the main frame beam are fixedly connected by the second expansion bolt. The flexible angle steel and the pre-fabricated perforated right-angle galvanized connector are respectively provided corresponding to the first channel steel beam and the second channel steel beam.

[0006] Preferably, the connecting body includes a panel beam and a web beam. The panel beam is vertically arranged and welded to the web beam as a whole. The web beam is arranged on one side of the panel beam and is perpendicular to the panel beam.

[0007] Preferably, a reinforcing block is provided at the connection between the panel beam and the web beam, and the reinforcing block is fixedly connected to the panel beam and the web beam.

[0008] Preferably, the cross-sections of the flexible angle steel and the prefabricated punched right-angle galvanized connector are both L-shaped.

[0009] Preferably, both the first and second channel steel beams are provided with mounting screw holes, and a first connecting bolt is provided between the flexible angle steel and the first channel steel beam, with the first connecting bolt corresponding to the mounting screw holes on the first channel steel beam. The flexible angle steel and the first channel steel beam are fixedly connected by the first connecting bolt.

[0010] Preferably, a second connecting bolt is provided between the prefabricated punched right-angle galvanized connector and the second channel steel beam, and the second connecting bolt is provided in correspondence with the assembly screw hole on the second channel steel beam. The prefabricated punched right-angle galvanized connector and the second channel steel beam are fixedly connected by the second connecting bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model device uses a first channel steel beam, a second channel steel beam, a flexible angle steel, and prefabricated perforated right-angle galvanized connectors. The flexible angle steel is connected to the first channel steel beam, connecting the blast-resistant wall to the connecting body. The prefabricated perforated right-angle galvanized connectors are connected to the second channel steel beam, connecting the main frame beam to the connecting body. The connection point is prone to forming a plastic hinge area under the impact of an explosion. The flexible angle steel deforms to a certain extent when impacted but will not break, thereby absorbing and dispersing the explosion energy and reducing the damage of the shock wave to the protected area.

[0013] 2. This utility model device, through the setting of panel beams, web beams and reinforcing blocks, uses panel beams and web beams made of high-strength and tough materials. The reinforcing blocks increase the structural strength of the main body and can withstand greater impact forces. When the panel is subjected to explosive impact, the web can absorb energy through deformation. The vertical setting of the panel beams and web beams provides sufficient deformation space, forming a plastic hinge area under explosive impact, which absorbs energy more fully, avoids structural failure caused by stress concentration, and reduces the transmission of impact force to the main frame beam.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a flexible connection structure for an blast-resistant wall, comprising a connecting body 1, a main frame beam 2, and an blast-resistant wall 3. A flexible angle steel 6 is provided on one side of the connecting body 1 and is welded integrally with the connecting body 1.
