Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially to a combined civil air defense pipe penetrating buffer support structure. BACKGROUND

[0002] In civil air defense projects, there are various pipelines. On the one hand, various pipelines will penetrate the wall from the outside of the building and then enter the interior of the civil air defense protective space. On the other hand, the pipelines can also extend from one protective space to another within the civil air defense project.

[0003] According to the civil air defense project specification, the wall-penetrating pipe structure of the civil air defense project must have the ability to resist shock waves and horizontal coupling to prevent damage to the interior of the protective space.

[0004] In the prior art, the wall-penetrating pipe structure of the civil air defense project is usually directly embedded in the reinforced concrete wall. However, this approach has many drawbacks. For example, during the threading operation, it is easy to cause the cable outer skin to break. Moreover, when encountering a larger horizontal load and shock wave, it is often difficult to rely solely on the wall-penetrating pipe itself to protect the internal structure, which can easily cause deformation of the wall-penetrating pipe and ultimately weaken the protective function of the entire structure.

[0031] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] See also Figs. 1-3 As shown, this application provides a combined personnel protection tube-penetrating buffer support structure, comprising:

[0033] Support tube 1;

[0034] Connecting sleeve 2, wherein the connecting sleeve 2 is disposed between the supporting tubes 1;

[0035] Inner tube 3, which is disposed inside the support tube 1, and multiple sets of buffer structures are provided between the outer circumference of the inner tube 3 and the inner circumference of the support tube 1. Each buffer structure includes multiple buffer components 4 spaced apart along the axis of the support tube 1.

[0036] The buffer component 4 includes:

[0037] Support bar 41, the two ends of the support bar 41 are disposed on the inner circumference of the support tube 1, and the middle part protrudes towards the inner tube 3 and contacts the outer circumference of the inner tube 3;

[0038] Elastic element 42 is disposed between the middle part of the support bar 41 and the inner circumference of the support tube 1.

[0039] Specifically, the support pipe 1 is typically made of high-strength metal materials, such as carbon steel or stainless steel. It possesses excellent compressive and impact resistance, capable of withstanding various physical forces from the external environment, such as pressure from building walls and vibrations during earthquakes. The connecting sleeve 2 is positioned between the support pipes 1, serving to connect and stabilize them. The connecting sleeve 2 is connected to the support pipe 1 via threaded connections or clamps, allowing for easy length adjustment according to usage requirements. The inner tube 3 is located inside the support pipe 1, further enhancing the protection of cables passing through the wall.

[0040] Multiple buffer structures are distributed between the outer circumference of the inner tube 3 and the inner circumference of the support tube 1. Each buffer structure consists of multiple buffer components 4 spaced apart along the axis of the support tube 1. The support bars 41 in the buffer components 4 are firmly fixed at both ends to the inner circumference of the support tube 1, and are generally made of metal with a certain degree of elasticity and strength. The middle part of the support bar 41 protrudes towards the inner tube 3 and contacts the outer circumference of the inner tube 3, forming a support point for the inner tube 3. When an external impact force acts on the support tube 1, the support bar 41 can disperse part of the impact force to the inner circumference of the support tube 1, reducing the direct impact on the inner tube 3 and the cable.

[0041] The elastic member 42 is arranged between the middle of the support strip 41 and the inner circumference of the support pipe 1. When the support pipe 1 is subjected to external impact, the elastic member 42 will be elastically deformed to absorb and disperse the impact force, thereby slowing down the force of the support strip 41 on the inner pipe 3. For example, when an earthquake occurs, the building wall may vibrate violently, causing the support pipe 1 to be subjected to a large impact force. At this time, the elastic member 42 can quickly respond to convert the impact force into elastic potential energy through its own deformation, and then slowly release, effectively protecting the inner pipe 3 and the internal wall-penetrating cable, avoiding damage to the cable due to excessive impact force.

[0042] The buffer assembly 4 further comprises:

[0043] A buffer layer 43 is filled between the support pipe 1 and the inner pipe 3.

[0044] Specifically, the buffer layer 43 is filled between the support pipe 1 and the inner pipe 3, enhancing the buffering effect of the structure. The buffer layer 43 is usually made of materials with excellent shock absorption and buffering performance, such as polyurethane foam and rubber particle filling materials. Polyurethane foam has the characteristics of light weight, good buffering performance and corrosion resistance, and can form a continuous and elastic buffer area between the support pipe 1 and the inner pipe 3. The rubber particle filling material can effectively absorb and disperse impact force from all directions due to the high elasticity of rubber itself, and the internal particle structure can further enhance the buffering effect.

[0045] The inner pipe 3 is provided with a protective layer 5.

[0046] Specifically, the protective layer 5 is made of rubber, which can buffer the wall-penetrating cable while reducing damage to the outside of the wall-penetrating cable when penetrating, and improve the protection of the wall-penetrating cable.

[0047] The two support pipes 1 are further provided with a fixing assembly 6, and the fixing assembly 6 comprises:

[0048] A first fixing seat 61 is arranged on the outer circumference of one of the two support pipes 1;

[0049] A second fixing seat 62 is arranged on the outer circumference of the other of the two support pipes 1;

[0050] A locking member 63 is arranged between the first fixing seat 61 and the second fixing seat 62.

[0051] Specifically, the first fixing seat 61 is fixed on the outer circumference of one of the support pipes 1, and is usually made of metal, such as carbon steel or stainless steel, which is compatible with the support pipe 1, to ensure that it has sufficient strength to withstand various stresses generated by subsequent connections. The second fixing seat 62 is arranged on the outer circumference of the other support pipe 1, and has the same structure, material and connection mode with the support pipe 1 as the first fixing seat 61, and is also fixed on the support pipe 1 by a reliable connection mode. The locking member 63 is installed between the first fixing seat 61 and the second fixing seat 62, and can adopt various forms, such as a screw-nut assembly, a high-strength buckle or a specially designed fastening chain. If the screw-nut assembly is adopted, the screw passes through the corresponding through holes pre-formed on the first fixing seat 61 and the second fixing seat 62, and then the screw is tightened by the nut, so that the two fixing seats are pulled close by the axial tension of the screw, thereby tightly fitting the two support pipes 1 together.

[0052] The locking member 63 is a lead screw.

[0053] The connecting sleeve 2 is threadedly connected with the support pipe 1.

[0054] The connecting sleeve 2 is provided with a plurality of fixing grooves for fixing the locking member 63.

[0055] Specifically, the connecting sleeve 2 is threadedly connected with the support pipe 1, and during installation, the construction personnel need to accurately align the external threads at the end of the support pipe 1 with the internal threads of the connecting sleeve 2, and then rotate the support pipe 1 clockwise to gradually screw the threads. During the screwing process, it is necessary to ensure that the support pipe 1 and the connecting sleeve 2 are coaxial to avoid the situation that the threads are skewed or stuck. In order to further improve the reliability of the connection, an appropriate amount of thread locking glue can be applied at the threaded connection, which can not only enhance the friction of the connection to prevent the threads from loosening due to vibration, but also play a certain sealing role to prevent foreign matters such as dust and water vapor from entering the inside of the support pipe 1.

[0056] The plurality of fixing grooves uniformly distributed on the connecting sleeve 2 cooperate with the lead screw to provide additional protection for the connection between the support pipes 1. After the lead screw passes through the first fixing seat 61 and the second fixing seat 62 and the nut is initially tightened, part of the rod body of the lead screw can be embedded in the fixing grooves of the connecting sleeve 2. The groove wall of the fixing groove plays a limiting role on the lead screw, effectively preventing the lead screw from rotating or displacing due to external forces such as vibration and impact during use. The distribution of the fixing grooves on the connecting sleeve 2 is uniform, so that the limiting force on the lead screw is uniformly distributed, avoiding damage to the lead screw or the connecting sleeve 2 due to excessive local stress.

[0057] The support pipe 1 is provided with a plurality of ribs 7 arranged at intervals on the outer circumference.

[0058] Specifically, the support pipe 1 is provided with a plurality of ribs 7 on the outer circumference, the ribs 7 are distributed on the outer circumference of the support pipe 1 at intervals, the ribs 7 enhance the anti-deformation ability of the support pipe 1, prevent the support pipe 1 from being excessively deformed or broken under stress, and ensure that the inner pipe 3 and the wall-penetrating cable inside are reliably protected. Moreover, when the support pipe 1 is cast in the wall, the ribs 7 can make the support pipe 1 better connected with the wall, reduce the probability of the support pipe 1 loosening in the wall, and improve the stability of the support pipe 1 after installation.
