Auxiliary steel pipe frame for facade renewal of old buildings

Abstract

The application discloses an auxiliary steel pipe frame for updating the outer facade of an old building, which comprises an outer sleeve, a steel pipe, an inner sleeve, and a support frame. The outer sleeve is wrapped around one end of the steel pipe and can rotate relative to the steel pipe around the axis of the steel pipe. The inner side of the sleeve is provided with a push rod, which is arranged inside the steel pipe. The inner sleeve is arranged on the inner side of the other end of the steel pipe. Limiting pieces are arranged between the inner sleeve and the steel pipe to prevent the relative rotation of the inner sleeve and the steel pipe. The inner sleeve can be telescopically moved relative to the steel pipe under the action of the push rod. The support frame is fixedly connected with the end of the inner sleeve. The support frame can be retracted into the inner side of the steel pipe. When the end of the inner sleeve extends out of the steel pipe, the support frame is unfolded and forms a 90-degree angle with the steel pipe. Through the structural arrangement of the steel pipe frame, the steel pipe frame can be simply fixed on the outer wall of the old building, thereby providing a support device for construction personnel.

[0037] Example 1

[0038] Reference Figures 1 to 8 As shown in the drawings, the present embodiment discloses a kind of auxiliary steel pipe frame for old building facade renewal. The auxiliary steel pipe frame includes: outer sleeve 1, steel pipe 2, clamp 3, inner sleeve 4 and support frame 5. In the present embodiment, the outer sleeve 1, inner sleeve 4 and support frame 5 are steel structure.

[0039] Preferably, the outer sleeve 1 is wrapped at one end of the steel pipe 2, and can rotate relative to the steel pipe 2 around the axis of the steel pipe 2, the inner side of the sleeve is provided with push rod 101, and the push rod 101 is arranged inside the steel pipe 2.

[0040] Further, the end of the push rod 101 is provided with an external thread structure which can be connected with the inner sleeve 4. In the embodiment, the outer sleeve 1 and the push rod 101 are integrally formed or connected by welding.

[0041] Preferably, the inner sleeve 4 is located at the other end of the steel pipe 2 and is arranged on the inner side of the steel pipe 2. The inner sleeve 4 and the steel pipe 2 are provided with a limiting piece to prevent relative rotation between the inner sleeve 4 and the steel pipe 2.

[0042] Preferably, the inner wall of the cylinder body 401 is provided with an internal thread 404; and the inner sleeve 4 can be telescopically moved relative to the steel pipe 2 under the action of the push rod 101.

[0043] Specifically, the outer wall of the cylinder body 401 of the inner sleeve 4 is provided with a rib plate 402 extending along the axial direction; the inner wall of the steel pipe 2 is provided with a groove-shaped sliding rail 201 extending along the axial direction; and the rib plate 402 is clamped in the sliding rail 201.

[0044] The outer wall of the cylinder body 401 is circumferentially provided with four rib plates 402 at equal angles; and the inner wall of the steel pipe 2 is provided with four sliding rails 201 corresponding to the rib plates 402 respectively.

[0045] Thus, the inner sleeve 4 and the steel pipe 2 are limited in the rotation direction by the rib plate 402 and the sliding rail 201, and the reciprocating movement of the inner sleeve 4 in the preset direction is facilitated.

[0046] Preferably, the support frame 5 is fixedly connected with the end of the inner sleeve 4; the support frame 5 can be retracted into the inner side of the steel pipe 2, and when the end of the inner sleeve 4 protrudes from the steel pipe 2, the support frame 5 is unfolded to form a 90° angle with the steel pipe 2.

[0047] Further, the end of the inner sleeve 4 is provided with four support frames 5 which are distributed at equal angles on the end face of the cylinder body 401.

[0048] Still further, the end face of the inner sleeve 4 is provided with a hole 403, and one end of the support frame 5 is fixed in the hole 403. In the embodiment, the support frame 5 is composed of a torsion spring.

[0049] Preferably, the clamp 3 is sleeved on the outer side of the steel pipe 2. The steel pipe 2 is limited by the clamp 3 and the support frame 5, so as to avoid movement when fixed on the outer wall.

[0050] Reference Figure 5As shown, when the steel pipe frame is in a non-working state, the support frame 5 is located inside the steel pipe 2, when the device needs to work, rotate the outer sleeve 1 counterclockwise, make the push rod 101 and the inner sleeve 4 relatively rotate, push the inner sleeve 4 outward, when the support frame 5 moves to the outside of the steel pipe, the torsional spring is in a natural open state, as shown in Figure 6 When the work is completed and the device needs to be recycled, rotate the outer sleeve 1 clockwise, the inner sleeve 4 and the support frame 5 move to the inside of the steel pipe, so that the device returns to the non-working state.

[0051] The steel pipe frame provided by the application enters through the air conditioner hole on the outer wall of the old building, rotates the outer sleeve 1 to make the support frame 5 open, and makes the support frame 5 support the inside of the wall, at this time, the steel pipe 2 is not easy to fall off from the wall. At the same time, the clamp 3 is locked at the position of the outer surface of the wall, so that the steel pipe 2 frame device and the outer wall form a relatively stable overall structure. When the outer facade is renovated and updated, the operator can tie the safety belt to the steel pipe frame to protect the personnel to carry out normal operation.

[0052] The above only describes the preferred embodiments of the application and is not used to limit the application, any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
