[0002] The balcony is an extension of the interior of the building. It is a place for residents to breathe fresh air, dry clothes, and place potted plants. Its design needs to take into account the principles of practicality and beauty. Balconies generally have three types: cantilevered, embedded, and corner. Balconies can not only allow residents to receive sunlight, absorb fresh air, exercise outdoors, watch, cool off, and dry clothes. With the increase of years of use, the balcony itself will age. The aging balcony has safety hazards in terms of stability. Therefore, reinforcement is often adopted to delay the service life of the balcony. Now, the balcony and the wall are reinforced by drilling holes and installing fixed frames. The balcony itself has aging problems. The balcony will also be damaged during the process of drilling holes in the balcony. After the balcony is drilled, the aging of the balcony will be aggravated during use, further reducing the service life of the balcony. Once the balcony of the old building has a tendency to crack, it needs to be reinforced after corresponding design. There is a lack of unified and reliable emergency treatment measures.

[0042] Specific implementation method eight: Combination Figures 1 to 15 To illustrate this embodiment, the reinforced balcony structure in this embodiment includes a balcony floor body 60 and at least two reinforcement units 61. At least two reinforcement units 61 are arranged at the bottom of the balcony floor body 60. The vertical end of each reinforcement unit 61 is connected to the building wall 62, and the horizontal end of each reinforcement unit 61 is connected to the bottom surface of the balcony floor body 60.

[0043] Furthermore, the number of reinforcement units 61 used is selected according to the specific emergency reinforcement needs and the aging and cracking conditions of the balcony floor body 60. Multiple reinforcement units 61 can be arranged along the length direction of the balcony floor body 60, or at least two reinforcement units 61 can be divided into two groups and arranged at the two ends of the balcony floor body 60 close to the building wall 62.

[0044] Furthermore, the gap between two adjacent reinforcement units 61 or their close proximity setting is selected according to the layout conditions and on-site reinforcement requirements.

[0045] Furthermore, when multiple reinforcement units 61 are installed closely together, the installation order can be the order of the actual installation positions on the balcony floor body 60 from the middle to the two ends. They can also be arranged in sequence along the length direction of the balcony floor body 60 to ensure that sufficient installation positions are reserved for the reinforcement units 61. The reinforcement units 6 can also be assembled as a whole structure and then installed between the balcony floor body 60 and the building wall 62, thereby forming a structural form that occupies a smaller space, which is conducive to completing the adaptation installation process in a narrow location.

[0046] The working principle of this utility model:

[0047] The first fixing rod 1, the second fixing rod 2 and the third fixing rod 3 in the reinforcement unit 61 are produced in a variety of sizes and specifications, so that the reinforcement unit 61 can be selected and matched accordingly when reinforcing balconies of different sizes, avoiding the need to splice or cut the reinforcement unit 61 when reinforcing the balcony floor slab body 60. When the size of the balcony is too large, a plurality of reinforcement units 61 can be arranged side by side under the balcony to reinforce the balcony. After measuring the balcony to be reinforced, the construction personnel select the first fixing rod 1, the second fixing rod 2 and the third fixing rod 3 of the corresponding length, and then Before the reinforcement unit 61 is installed in the building wall 62, the construction workers insert the first clamping block 21 into the second slot 19, and then screw the first bolt 6 into the second thread groove 20 and the third thread groove 22 for fixation. The second clamping block 23 is inserted into the first slot 17, and then screwed into the first thread groove 18 and the fourth thread groove 24 for fixation by the second bolt 7. Then the construction workers complete the installation of the connecting rod 16 by screwing the fourth bolt 54 into the first positioning thread groove 50 and the third positioning thread groove 52, and the fifth bolt 55 into the second positioning thread groove 51 and the fourth positioning thread groove 53, thereby completing the installation preparation work.

[0048] The construction workers first use an electric drill to drill a hole corresponding to the first opening 5 at a preset position below the balcony floor body 60, and then the construction workers transport the assembled reinforcement unit 61 to the preset position, set the first opening 5 coaxially with the opening on the building wall 62, and install expansion screws between the first opening 5 and the opening on the building wall 62 to achieve connection, thereby completing the process of fixing the reinforcement unit 61 on the outer wall of the building wall 62. The building wall 62 is a load-bearing wall of the building with a balcony, and the installation of the reinforcement unit 61 on the balcony floor body 60 is completed.

[0049] The construction workers then twist the second threaded rod 29 to make the first movable plate 8 extend out of the third slot 25 until the top of the first movable plate 8 abuts against the bottom of the balcony floor body 60, and then stop twisting the second threaded rod 29. They twist the third threaded rod 39 to make the second movable plate 9 extend out of the fifth slot 34, and then stop twisting the third threaded rod 39 until the second movable plate 9 abuts against the bottom of the balcony floor body 60.

[0050] The construction personnel screw the fourth threaded rod 44 to make the first movable block 11 move upward inside the sixth groove 40 until the second movable block 42 abuts the balcony floor body 60, so that after the reinforcement unit 61 reinforces the balcony floor body 60, in the daily use of the balcony, the vibration generated by the balcony when people walk on the balcony will be transmitted to the second movable block 42, and then the second movable block 42 moves inside the seventh groove 45 and squeezes the spring 48 and the damping rod 49. By transmitting the vibration to the spring 48 and the damping rod 49, the vibration generated during the use of the balcony can be weakened, thereby reducing the impact force of the balcony on the reinforcement unit 61 during use, and extending the service life of the reinforcement unit 61 and the balcony floor body 60.

[0051] During the use of the balcony, due to the aging of the balcony, cement blocks may fall from the bottom of the balcony. At this time, the fallen cement blocks will be caught by the fixing plate 10 to prevent the cement blocks from falling directly and injuring pedestrians, thereby increasing the convenience of installation of the reinforcement unit 61 during emergency use. Since there is a certain distance between the top of the fixing plate 10 and the bottom of the third fixing rod 3 and the fourth fixing rod 4, the cement blocks that fall on the fixing plate 10 can also be cleaned, further increasing the convenience of installation of the reinforcement unit 61 during emergency use.

[0052] When it is necessary to dismantle the balcony floor slab body 60 for reconstruction, the construction workers can dismantle the old balcony, install the steel bars at the original position, and then place the concrete pouring plate on the top of the fixed plate 10. At this time, the height of the concrete pouring plate can be adjusted by adjusting the position of the first movable block 11, thereby adjusting the pouring thickness of the concrete, and increasing the installation convenience of the reinforcement unit 61 during emergency use. If the size of the balcony is too large, an appropriate number of reinforcement units 61 can be installed under the balcony for emergency reinforcement according to actual needs.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
