Description

Technical Field

[0001] This invention belongs to the field of civil defense engineering technology, and in particular relates to an adjustable support device for the door frame of a civil defense door and its construction method. Background Technology

[0002] Currently, all large-scale civil defense projects under construction are designed with civil defense doors to ensure wartime protection effectiveness. These doors have heavy frames and are considered heavy protective equipment, and the installation process requires extremely high positioning accuracy and support stability.

[0003] In existing technologies, for the installation of such air-raid shelter door frames, construction teams typically use simple steel pipes and welded steel bars as temporary supports, in conjunction with tower cranes for positioning and support. Due to varying worker skill levels, door frame positioning is difficult, construction efficiency is low, verticality deviations are significant, and support stability is poor. This makes it easy for door frames to shift during concrete pouring, compromising construction quality. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an adjustable support device and construction method for the door frame of a civil defense door, which effectively solves the technical problems of difficult positioning operation of the door frame of a civil defense door, low construction efficiency, large verticality deviation, and poor support stability, and overcomes the shortcomings of the prior art.

[0005] The technical solution adopted in this invention is: an adjustable support device for the frame of a civil defense door, comprising:

[0006] The upper inclined support tube is hinged to the door frame at one end and movably connected to one end of the connector at the other end.

[0007] The lower inclined support pipe is hinged at one end to the concrete foundation and movably connected at the other end to the other end of the connector.

[0008] An adjusting component, disposed on the connector, is used to adjust the relative positions of the upper and lower inclined support tubes with respect to the connector;

[0009] A locking element is provided on the adjusting element.

[0010] Furthermore, the two ends of the connector are respectively provided with threads, and the threads are turned in opposite directions. The end of the upper inclined support tube near the connector is threadedly connected to the connector, and the end of the lower inclined support tube near the connector is threadedly connected to the connector.

[0011] Furthermore, the connector has a through hole in the middle, and the adjusting member passes through the through hole.

[0012] Furthermore, the adjusting component includes a vertically arranged connecting rod and an adjusting rod, the connecting rod passing through the through hole, and the locking component being sleeved on the connecting rod.

[0013] Furthermore, the connecting rod is configured as a screw, and the locking element is configured as a nut.

[0014] Furthermore, the outer periphery of the connection ends of the upper and lower inclined support tubes and the connector is provided with positioning grooves, which can be engaged with both ends of the adjusting rod.

[0015] Furthermore, multiple positioning slots are provided, arranged circumferentially along the upper and lower inclined support tubes.

[0016] Furthermore, the top of the door frame is provided with a first connecting ear, and the end of the upper inclined brace tube away from the connector is hinged to the first connecting ear.

[0017] Furthermore, an embedded plate is provided on the concrete foundation, and a second connecting lug is provided on the embedded plate. The end of the lower inclined support tube away from the connector is hinged to the second connecting lug.

[0018] The present invention also provides a construction method for using an adjustable support device for a civil defense door frame as described above, comprising the following steps:

[0019] The upper and lower inclined support tubes are movably connected using connectors.

[0020] The end of the upper diagonal brace tube away from the connector is hinged to the door frame;

[0021] The end of the lower inclined support tube away from the connector is hinged to the concrete foundation;

[0023] The adjusting member is locked in place using the locking mechanism.

[0024] The advantages and positive effects of this invention are:

[0025] 1. By setting up threaded upper diagonal bracing pipes, connectors and lower diagonal bracing pipes, the support for both sides of the door frame of the air-raid shelter and the adjustment of the verticality of the door frame are realized, which greatly shortens the time occupied by the tower crane. After the hoisting is completed, the hook can be detached, thus improving the turnover efficiency of the tower crane.

[0026] 2. By setting up adjustment components, the operation steps are simplified, the difficulty of adjusting the verticality of the door frame is reduced, the verticality deviation is decreased, production efficiency is improved, and the construction period is shortened.

[0035] This invention provides an adjustable support device for the frame of a civil defense door and a construction method thereof. The embodiments of this invention will be described below with reference to the accompanying drawings.

[0036] In the description of the embodiments of this invention, it should be understood that the terms "top," "bottom," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0037] like Figure 1 As shown in the figure, an adjustable support device for a civil defense door frame is provided in this embodiment of the invention. The support device is symmetrically arranged on both sides of the door frame 15, used to adjust the verticality of the door frame 15 and to support it. The support device includes an upper inclined support tube 1, a lower inclined support tube 2, a connector 3, and an adjusting component. One end of the upper inclined support tube 1 is hinged to the door frame 15, and the other end is movably connected to one end of the connector 3. One end of the lower inclined support tube 2 is hinged to the concrete foundation 16, and the other end is movably connected to the other end of the connector 3. The upper inclined support tube 1, the connector 3, and the lower inclined support tube 2 are coaxially arranged, forming the support rods for supporting the door frame 15. Since both the upper inclined support tube 1 and the lower inclined support tube 2 are movably connected to the connector 3, the length of the entire support rod can be adjusted by adjusting the relative positions of the upper and lower inclined support tubes 1 and 2 with the connector 3, thereby adjusting the verticality of the door frame 15. An adjusting component is mounted on the connecting component 3 to adjust the relative positions of the upper inclined support tube 1 and the lower inclined support tube 2 with respect to the connecting component 3. A locking component 7 is mounted on the adjusting component to lock it in place, thereby improving the stability of the entire support device.

[0038] Specifically, both ends of the connector 3 are threaded with opposite directions of rotation. The end of the upper inclined support tube 1 closest to the connector 3 is threaded to the connector 3, and the end of the lower inclined support tube 2 closest to the connector 3 is also threaded to the connector 3. The upper and lower inclined support tubes 1 and 2 are tubes, and the connector 3 is a cylindrical rod. Both ends of the upper and lower inclined support tubes 1 and 2 closest to the connector 3 are internally threaded with opposite directions of rotation. One end of the connector 3 is inserted into the upper inclined support tube 1, matching its internal thread, and the other end is inserted into the lower inclined support tube 2, matching its internal thread. By rotating the connector 3, the lengths of both ends inserted into the upper and lower inclined support tubes 1 and 2 can be adjusted simultaneously, thereby adjusting the support length of the entire support rod and adjusting the verticality of the door frame 15.

[0039] Specifically, in order to facilitate the rotation of the connector 3, a through hole 6 is provided in the middle of the connector 3, and the adjusting member is inserted into the through hole 6. The connector 3 can be rotated by holding the adjusting member.

[0040] like Figure 2 As shown, the adjusting component includes a vertically arranged connecting rod 4 and an adjusting rod 5. One end of the connecting rod 4 is fixedly connected to the middle of the adjusting rod 5, forming a T-shape. The connecting rod 4 passes through the through hole 6, and the adjusting rod 5 is arranged parallel to the supporting rod. During operation, the operator can manually hold the adjusting rod 5 and rotate the connecting component 3 via the connecting rod 4. Figure 3 As shown, after the verticality of the door frame 15 is adjusted, the two ends of the adjusting rod 5 are pressed against the outside of the upper inclined support tube 1 and the lower inclined support tube 2. The locking piece 7 is then inserted from the end of the connecting rod 4 to lock the connecting piece 3, preventing the connecting piece 3 from loosening and the support from becoming unstable due to concrete vibration during subsequent concrete pouring. Preferably, the connecting rod 4 is a screw rod, and the locking piece 7 is a nut.

[0041] Preferably, the outer periphery of the connection ends of the upper inclined support tube 1 and the lower inclined support tube 2 with the connector 3 is fixed with positioning grooves 8, which can engage with both ends of the adjusting rod 5. Multiple positioning grooves 8 are provided, evenly distributed along the circumference of the upper inclined support tube 1 and the lower inclined support tube 2. The positioning grooves 8 of the upper inclined support tube 1 and the lower inclined support tube 2 are aligned to ensure that both ends of the adjusting rod 5 can engage with the positioning grooves 8 when rotated to any angle along the circumference.

[0042] Specifically, the top of the door frame 15 is fixed with a first connecting ear 9, and the end of the upper inclined support tube 1 away from the connector 3 is hinged to the first connecting ear 9 by a first pin 10.

[0043] Specifically, such as Figure 4 As shown, an embedded plate 11 is provided on the concrete foundation 16, and a second connecting lug 12 is fixed on the embedded plate 11. The end of the lower inclined support pipe 2 away from the connected part 3 is hinged to the second connecting lug 12 by a second pin 13. Anchor holes 14 are provided on the embedded plate 11, which are fixedly connected to the embedded anchors on the concrete foundation 16.

[0044] A construction method for using an adjustable support device for a civil defense door frame as described above includes the following steps:

[0045] S1. Determine the position of the door frame 15 of the air-raid shelter according to the drawings, and install the embedded plate 11;

[0046] S2. Weld the first connecting lug 9 to the top of the door frame 15;

[0047] S3. Use a tower crane to hoist the door frame 15 to the installation position;

[0048] S4. Connect the upper inclined support tube 1 and the lower inclined support tube 2 to the two ends of the connector 3 respectively. Hinge the end of the upper inclined support tube 1 away from the connector 3 with the first connecting ear 9 using the first pin 10. Hinge the end of the lower inclined support tube 2 away from the connector 3 with the second connecting ear 12 on the embedded plate 11 using the second pin 13.

[0049] S5. The operator inserts the connecting rod 4 of the adjusting component into the through hole 6 of the connecting component 3. The adjusting rod 5 is set parallel to the connecting component 3. Holding the adjusting rod 5, the operator rotates the connecting component 3 through the connecting rod 4 to adjust the length of the two ends of the connecting component 3 inserted into the upper inclined support tube 1 and the lower inclined support tube 2, thereby adjusting the support length of the entire support rod and pushing and pulling the door frame 15 to adjust the verticality of the door frame 15.

[0050] S6. After the verticality of the door frame 15 is adjusted, the two ends of the adjusting rod 5 are respectively engaged in the positioning grooves of the upper inclined support tube 1 and the lower inclined support tube 2. The locking piece 7 is then inserted from the end of the connecting rod 4 to further lock the connecting piece 3.

[0051] S7. After inspection and verification, concrete pouring shall be carried out.

[0052] S8. Once the concrete strength reaches the set requirements, the support device can be removed and recycled.
