Description

Technical Field

[0001] The utility model relates to the technical field of balcony structures, in particular to an integrated hoisting balcony structure. Background Art

[0002] With more and more urban renovation projects, the five- and six-story old houses built before 2000, referred to as tube buildings, have neither elevators nor balconies. In the design of the renovation plan, in order to improve the architectural quality of the original houses, it is considered to add balconies. However, adding balconies to old brick-concrete structures is a technical problem.

[0003] The existing conventional method is to use a newly built independent frame as a balcony. The balcony structure is built close to the original house, and the balcony structure is separated from the original structure by a seam. This method does not affect the original structure, but the foundation of the new structure is too close to the foundation of the original structure and cannot be constructed. The new frame has many additional columns, which is not beautiful and cannot be made into a cantilevered balcony. The construction period is also long. Summary of the invention

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide an integrated hoisting balcony structure. The balcony structure is made in a steel structure factory and hoisted and installed on site at one time. It consists of two columns and a balcony platform. It is not only a cantilevered balcony with beautiful facade, but also occupies a very small area. It is also very fast to install, greatly shortening the construction period. It has a simple structure, light overall weight of the balcony, and fast structural installation speed.

[0005] The technical solution adopted by the utility model to achieve its technical purpose is: an integrated hoisting balcony structure, including two parallel placed steel columns, one side of the steel column is fixed to the outer wall by a post-anchor bolt, and the other side is fixed with a cantilevered steel beam, every two cantilevered steel beams are set at the same height according to the balcony position, the height of the steel column is set according to the floor height, and the cantilevered steel beams are arranged in multiple layers according to the number of balconies.

[0006] A patterned steel plate is fixed between every two cantilevered steel beams, a flat steel is fixed on one side of the patterned steel plate, and a concrete cushion layer is poured on the other side. There are multiple flat steels, and the cross-sections of the flat steels at the two ends are set as bending structures, and the cross-sections of the remaining flat steels are set as rectangular structures.

[0007] Connecting steel beams are fixed at both ends of the flat steel and the patterned steel plate, and both ends of the connecting steel beam are respectively fixed on the steel column and the cantilever steel beam.

[0008] Preferably, a stiffening plate is fixed inside the steel column and a slot-shaped hole is opened. The stiffening plate increases the stability of the steel column, and the slot-shaped hole facilitates the connection of post-anchor bolts to fix the steel column to the outer wall of the floor.

[0009] Preferably, a variable-section inclined steel column is fixed at the bottom of the steel column, and the bottom of the variable-section inclined steel column is fixed to a strip foundation that has been compacted and cast on the ground by pre-buried anchor bolts. On the one hand, the variable-section inclined steel column is convenient for supporting the steel column and concentrating the support points, and on the other hand, it is convenient for providing supporting force for the steel column against the wall, thereby reducing the connection pressure of the post-anchor bolts.

[0010] Preferably, the thickness of the flat steel and patterned steel plate is 5 mm, and the thickness of the concrete cushion layer is 50 mm.

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

[0012] The integrated hoisting balcony structure is manufactured in a steel structure factory and installed on site in one go. It is not only a cantilevered balcony with beautiful facade and small footprint, but also has a very fast installation speed, which greatly shortens the construction period. The structure is simple, consisting of two columns and a balcony platform. The balcony has a light overall weight and a fast structural installation speed. After hoisting, only the anchor bolts and post-anchor bolts need to be installed.

[0013] The integrated hoisting balcony structure has a small impact of the balcony load on the original structure. The balcony load is borne by the newly built strip foundation. The balcony is attached to the original building. The original building has a certain limiting displacement effect on the balcony. The connection between the balcony and the original building is a detachable connection, which can fully release the vertical displacement and eliminate the problem of uneven foundation settlement.

[0027] Specific as Figure 1 As shown, a variable-section inclined steel column 102 is fixed at the bottom of the steel column 1. The bottom of the variable-section inclined steel column 102 is fixed to the strip foundation 3 that has been compacted and cast on the ground through pre-buried anchor bolts 104. The variable-section inclined steel column 102 is convenient for supporting the steel column 1 and concentrating the support points on the one hand, and is convenient for providing supporting force for the steel column 1 against the wall on the other hand, thereby reducing the connection pressure of the post-anchor bolts 103.

[0028] Specific as Figure 2 , 3 As shown, a patterned steel plate 402 is fixed between every two cantilevered steel beams 101, a flat steel 401 is fixed on one side of the patterned steel plate 402, and a concrete cushion layer 403 is poured on the other side. There are multiple flat steels 401, and the cross-sections of the flat steels 401 at the two ends are set as a bending structure, and the cross-sections of the remaining flat steels 401 are set as a rectangular structure. The thickness of the flat steel 401 and the patterned steel plate 402 is 5 mm, and the thickness of the concrete cushion layer 403 is 50 mm.

[0029] Specific as Figure 2 As shown, connecting steel beams 4 are fixed at both ends of the flat steel 401 and the patterned steel plate 402 , and both ends of the connecting steel beam 4 are respectively fixed on the steel column 1 and the cantilever steel beam 101 .

[0030] Specifically, the integrated hanging balcony structure is composed of two columns and a balcony platform. The balcony platform is welded together by flat steel 401, patterned steel plate 402, cantilever steel beam 101 and connecting steel beam 4, and then formed by laying a concrete cushion layer 403. The overall deadweight is relatively light;

[0031] During installation, since the entire structure is constructed with steel structure, it is installed through one-time hoisting on site. After hoisting, only the embedded anchor bolts 104 and the post-anchor bolts 103 need to be installed. The embedded anchor bolts 104 are installed on the newly built strip foundation 3, which is easy to install.

[0032] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model.
