Description

Technical Field

[0001] The present application relates to the field of civil air defense engineering, and in particular to an outer side blocking structure of a civil air defense wall opening. Background Art

[0002] Civil defense walls are separate protective structures built to provide shelter for personnel and supplies, civil air defense command, and medical assistance during wartime. Civil defense wall openings are holes or openings reserved or opened in the main structure during construction to meet specific functional requirements. Due to evolving user needs, the originally designed openings often fail to meet these requirements, necessitating the sealing of these openings.

[0003] In the related art, the openings in civil air defense walls are usually sealed by directly planting reinforcement bars inside the openings and filling the openings with cement mortar, plain concrete, etc. to complete the sealing of the openings.

[0004] However, it is very difficult to plant reinforcement inside the hole, and the construction quality is difficult to guarantee, which can easily lead to the hole being poorly sealed. Utility Model Content

[0005] In order to ensure that the opening is sealed more firmly, the present application provides an outer side sealing structure of the opening of a civil defense wall.

[0006] The present application provides an outer side blocking structure for a civil defense wall opening, which adopts the following technical solutions:

[0007] A structure for sealing an opening in a civil defense wall on the outside, comprising an existing wall, an existing opening being opened on the existing wall, a later-added sealing wall being fixedly connected to one side of the existing wall for sealing the existing opening, connecting ribs being pre-embedded and fixedly connected in each side of the later-added sealing wall tightly attached to the existing wall, a plurality of connecting grooves corresponding to the number of the connecting ribs being opened on the existing wall, and an end of each connecting rib away from the later-added sealing wall being inserted into a corresponding connecting groove and fixedly connected to the existing wall.

[0008] By adopting the above technical solution, a post-added blocking wall is constructed on one side of the existing wall. The post-added blocking wall is fixedly connected to the existing wall to block the existing opening, and the provision of connecting reinforcement strengthens the connection between the existing wall and the post-added blocking wall. In this way, the existing opening is blocked more tightly and firmly.

[0009] Preferably, at least two hidden piles are embedded in and fixedly connected to the later added blocking wall, and each hidden pile is pre-buried in the ground.

[0010] By adopting the above technical solution, hidden piles are constructed and pre-buried on the ground, and then the hidden piles are built inside the later added blocking wall, thereby ensuring the support of the ground for the later added blocking wall.

[0011] Preferably, a plurality of supporting vertical steel bars are fixedly connected inside the concealed pile, and a supporting tie bar is fixedly connected between every two adjacent supporting vertical steel bars.

[0012] By adopting the above technical solution, the setting of supporting vertical steel bars and supporting tensioning increases the stability and safety of the hidden piles, and reduces the occurrence of damage or collapse of the hidden piles.

[0013] Preferably, a plurality of stirrups arranged along the height direction of the hidden pile are fixedly connected inside the hidden pile.

[0014] By adopting the above technical solution, the installation strength is enhanced, and the shear strength, bending strength and overall stability of the concealed piles are significantly improved.

[0015] Preferably, a plurality of installed vertical steel bars and a plurality of installed horizontal steel bars are fixedly connected inside the post-added blocking wall.

[0016] By adopting the above technical solution, the arrangement of multiple installed vertical steel bars and multiple installed horizontal steel bars can significantly improve the bearing capacity, stability and seismic performance of the subsequent added blocking wall.

[0017] Preferably, an installation tie bar is fixedly connected between every two adjacent installation vertical steel bars.

[0018] By adopting the above technical solution, the integrity and stability of the post-added blocking wall are enhanced, and the occurrence of problems such as cracking and deformation is reduced.

[0019] Preferably, a concrete layer is fixedly connected to each of the connecting grooves, and the concrete layer wraps around the connecting ribs inserted into the connecting grooves and is fixedly connected to the connecting ribs.

[0020] By adopting the above technical solution, concrete is poured into the connection groove, and then the connection reinforcement is inserted into the corresponding connection groove. After the concrete solidifies into a concrete layer, the concrete layer fixes the connection reinforcement in the existing wall.

[0021] Preferably, each of the connecting grooves is provided with a thread, and the outer wall of each connecting rib is also provided with a thread, and the connecting rib is inserted into the connecting groove and is threadedly connected to the existing wall.

[0022] By adopting the above technical solution, one end of each connecting bar is rotated and threadedly connected to the existing wall, and then the subsequent blocking wall is built, and the other end of each connecting bar is fixed inside the subsequent blocking wall. In this way, the installation of the connecting bar is completed, making the connection between the existing wall and the subsequent blocking wall more firmly.

[0023] Preferably, a plurality of reinforcing bars are fixedly connected to the interior of the later-added blocking wall, a concrete block is fixedly connected to the interior of the existing opening, the concrete block is fixedly connected to the later-added blocking wall, and one end of each reinforcing bar is inserted into and fixedly connected to the concrete block.

[0024] By adopting the above technical solution, concrete is poured into the existing opening until the concrete forms a concrete block that blocks the existing opening. At this time, each reinforcing bar is fixed inside the concrete block, strengthening the connection between the later added blocking wall and the concrete block.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The existing openings are sealed tightly and firmly;

[0027] 2. Reduce the occurrence of problems such as cracking and deformation of the subsequent anti-blocking wall;

[0028] 3. The connection between the existing wall and the newly added blocking wall is relatively firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0033] Example 1

[0034] The embodiment of the present application discloses an outer side blocking structure of a civil defense wall opening. Figure 1 and Figure 2 The outer blocking structure includes an existing wall 1, on which an existing opening 11 is opened. In order to effectively block the existing opening 11, a subsequent blocking wall 2 is fixedly connected to one side of the existing wall 1 by pouring concrete to block the existing opening 11.

[0035] Multiple connecting ribs 3 are embedded and fixed on each side of the additional blocking wall 2 that abuts the existing wall 1. Each sidewall of the existing wall 1 that contacts the additional blocking wall 2 is provided with multiple connecting grooves 12, one for each connecting rib 3. The other end of each connecting rib 3 is inserted into the corresponding connecting groove 12 on the existing wall 1. Through methods such as concrete pouring, a secure connection is achieved with the existing wall 1, further enhancing the stability of the blocking structure and strengthening the connection between the two walls.

[0036] In this embodiment, the connection grooves 12 are securely connected to the connecting ribs 3 by pouring concrete. Concrete is poured into each connection groove 12. When the connecting ribs 3 are inserted into the connection grooves 12, the concrete tightly wraps around the connecting ribs 3. After the concrete in the connection grooves 12 solidifies, a concrete layer 4 is formed. The provision of the concrete layer 4 ensures a secure connection between the connecting ribs 3 and the existing wall 1.

[0037] At least two concealed piles 5 are embedded within the post-addition blocking wall 2, each pre-buried in the ground, ensuring effective ground support for the post-addition blocking wall 2. To enhance the stability and safety of the concealed piles 5, multiple supporting vertical steel bars 51 are fixedly connected to each pile 5. Supporting tie bars 52 are fixedly connected between each two adjacent supporting vertical steel bars 51, forming a stable steel grid structure. Furthermore, multiple stirrups 53 are arranged along the height of the concealed piles 5, significantly enhancing their strength, shear resistance, bending resistance, and overall stability.

[0038] Within the post-addition blocking wall 2, multiple vertical reinforcement bars 21 and horizontal reinforcement bars 22 are fixedly connected to form a grid structure, significantly enhancing the wall's load-bearing capacity and seismic resistance. Tie bars 23 are added between each pair of adjacent vertical reinforcement bars 21, strengthening the wall's internal connectivity, improving its integrity and stability, and reducing potential cracking and deformation over time.

[0039] To further enhance the stability of the sealing structure, this embodiment adds multiple reinforcing bars 54 to the interior of the later-added sealing wall 2 and casts a concrete block 6 within the existing opening 11. One end of the reinforcing bar 54 is inserted into the concrete block 6, where it is fixedly connected. This strengthens the connection between the later-added sealing wall 2 and the existing wall 1, enhancing the load-bearing capacity and safety of the entire sealing structure.

[0040] The principle behind the exterior sealing structure for a civil defense wall opening in this embodiment is to construct a subsequent sealing wall 2 on the side of an existing wall 1, creating a stable and seismically resistant exterior sealing structure. This structure effectively seals an existing opening 11 in the civil defense wall, ensuring safety and stability, and offers significant practicality and improvement in practical applications.

[0042] The embodiment of the present application discloses an outer side blocking structure of a civil defense wall opening. Figure 1 The difference from the first embodiment is that threads are respectively provided on the inner wall of the connecting groove 12 and the outer wall of the connecting rib 3, and the connecting rib 3 is inserted into the connecting groove 12 and is tightly fitted with the existing wall 1 through threaded connection.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
