Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to an assembled building balcony. Background Art

[0002] Prefabricated construction refers to a construction method in which the building structure or components are prefabricated in a factory and then transported to the site for assembly and installation. This construction method has many advantages over traditional on-site construction, including fast construction speed, controllable quality, and environmental protection.

[0003] In order to protect the safety of construction workers and owners, protective fences need to be installed on the balcony. Prefabricated balconies are generally not equipped with fences for the convenience of transportation and movement. In order to prevent the fences from being easily damaged or knocked during the lifting and installation process, workers are usually arranged to drill holes on the balcony and install the fences with expansion screws after the balcony installation and pouring are completed. However, this method does not make the connection between the fence and the balcony base strong enough, and the secondary installation of the fence wastes manpower and material resources, which prolongs the construction period of the prefabricated building. Utility Model Content

[0004] The utility model provides an assembled building balcony, which has the characteristics of saving manpower and material resources and shortening the construction period of the assembled building.

[0005] The utility model provides the following technical solution: the utility model comprises a building body, a balcony base plate and a protective fence, a side beam is cast above the balcony base plate, a casting trough is arranged inside the side beam, inner and outer walls for contacting the building body are extended at both ends of the side beam, the bottom of the inner wall is higher than the bottom of the outer wall, and a plurality of reserved steel bars are extended at both ends of the balcony base plate and the building body close to each other;

[0006] The protective fence includes columns and U-shaped cross bars, the columns include hollow columns and solid columns, the hollow columns and the solid columns are of equal length, the solid column damping sliding is arranged inside the hollow columns, the top of the solid column is fixedly connected with the U-shaped cross bar, and the bottom of the hollow column is pre-cast inside the casting trough.

[0007] The body of the hollow column is penetrated by an anti-slip groove, and the solid column is symmetrically provided with two rows of clamping blocks on the circumferential surface near the bottom, and the clamping blocks are slidably arranged inside the limiting groove.

[0008] Wherein, an extension plate is arranged at one end of the building body adjacent to the balcony base plate.

[0009] Wherein, a grouting mold plate is movably arranged in the middle of the inner wall.

[0010] Wherein, a positioning groove is provided at one end of the balcony base plate adjacent to the building main body.

[0011] Wherein, a waterproof strip is fixedly provided on the side of the U-shaped cross bar.

[0012] The beneficial effect of the utility model is that when the balcony is cast in the factory, the bottom of the hollow column is cast on the bottom of the casting trough through concrete, and the solid column damping slides inside the hollow column. At this time, the protective fence can be completely placed inside the casting trough, which is convenient for subsequent movement and lifting. After lifting in place, the balcony can be installed. At this time, the inner and outer walls on both sides are in contact with the wall surface of the building main body, and the extension plate at the bottom is in contact with the positioning groove. Due to the height difference between the bottoms of the inner and outer walls, a U-shaped casting area is formed between the building main body and the balcony substrate. The U-shaped area to be cast is completely closed by the grouting mold plate, and the casting trough and the area to be cast are connected. By pouring concrete into the casting trough, the concrete flows downward into the area to be cast between the balcony substrate and the building main body under the influence of gravity, thereby realizing the fixation of the balcony and the building main body. When the casting of the casting trough is completed, the protective fence is also installed. The balcony casting and the installation of the fence can be carried out simultaneously, avoiding the waste of resources caused by the secondary installation of the fence and reducing the construction period of the prefabricated building.

[0013] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-Figure 5The utility model provides the following technical solutions: the utility model includes a building body 6, a balcony base plate 1 and a protective fence. A side beam 2 is cast above the balcony base plate 1, and a casting trough 21 is arranged inside the side beam 2. The inner wall 22 and the outer wall 23 for contacting the building body 6 are extended at both ends of the side beam 2. The bottom of the inner wall 22 is higher than the bottom of the outer wall 23. A plurality of reserved steel bars 12 are extended at both ends of the balcony base plate 1 and the building body 6 that are close to each other; the protective fence includes a column 3 and a U-shaped cross bar 4. The column 3 includes a hollow column 31 and a solid column 32. The hollow column 31 and the solid column 32 are of equal length. The solid column 32 is slidably arranged inside the hollow column 31. The top of the solid column 32 is fixedly connected with the U-shaped cross bar 4, and the bottom of the hollow column 31 is pre-cast inside the casting trough 21.

[0021] In this embodiment: the casting trough 21 is designed to accommodate the protective fence, the extended inner wall 22 and outer wall 23 can facilitate the positioning of the balcony during installation, and the height difference between the bottom of the inner wall 22 and the outer wall 23 is to connect the casting trough 21 and the area to be cast between the building body 6 and the balcony substrate 1. The casting of the balcony and the installation of the protective fence can be achieved in one casting. By welding and bundling the steel bars extending from both ends of the balcony substrate 1 and the building body 6, a new reinforced concrete structure is formed in the area to be cast between the balcony substrate 1 and the building body 6, which increases the stability of the connection between the balcony and the building body 6; the lengths of the hollow columns 31 and the solid columns 32 are both less than the height of the side beams 2. By setting the solid columns 32 and the hollow columns 31, the protective fence can be stored in the inside of the casting trough 21, and the protective fence and the balcony substrate 1 can be combined together in advance, which is convenient for subsequent lifting and installation.

[0022] The body of the hollow column 31 is penetrated by an anti-slip groove 311, and two rows of blocks 321 are symmetrically arranged on the circumferential surface near the bottom of the solid column 32, and the blocks 321 are slidably arranged inside the limiting groove; the anti-slip groove 311 is a main body that penetrates the hollow column 31, and can fill the hollow column 31 after concrete is poured, thereby increasing the stability of the hollow column 31. The design of the two rows of blocks 321 increases the contact area between the bottom of the solid column 32 and the concrete, making the solid column 32 more difficult to pull out and shake, thereby increasing the overall stability of the protective fence.

[0023] An extension plate 61 is provided at one end of the building body 6 adjacent to the balcony substrate 1; the setting of the extension plate 61 can increase the contact area between the building body 6 and the balcony substrate 1, making the casting of the balcony substrate 1 more stable, and the extension plate 61 located at the bottom of the area to be cast can support the casting material above, without the need to use an additional casting template at the bottom.

[0024] A grouting mold plate 5 is movably provided in the middle of the inner wall 22; the grouting mold plate 5 can be fixed above the area to be poured between the building main body 6 and the balcony substrate 1 by bolts or pressure plates, forming a closed pouring space with the inner and outer walls 23 and the extension plate 61 at the bottom. The contact between the grouting mold plate 5 and the building main body 6 and the balcony substrate 1 must be coated with sealant before pouring to prevent leakage of the pouring material.

[0025] A positioning groove 11 is provided at one end of the balcony substrate 1 adjacent to the building main body 6; the design of the positioning groove 11 facilitates the workers to position the balcony when installing it. During installation, the positioning groove 11 can be brought into contact with the extension plate 61 on the building main body 6 to complete the positioning of the balcony substrate 1 without the need for additional marking or measurement.

[0026] A waterproof strip 41 is fixedly provided on the side of the U-shaped cross bar 4; the gap between the U-shaped cross bar 4 and the casting trough 21 is filled with the side waterproof strip 41 to reduce the corrosion of the protective fence in the casting trough 21 by rainwater or pollutants before the fence is installed. The waterproof strip 41 is made of silicone rubber and can be used as a protective pad after the protective fence is installed, making it more comfortable for the owner to lean on the protective fence when sightseeing on the balcony.

[0027] The working principle and use process of the utility model are as follows: when pouring the balcony in the factory, the bottom of the hollow column 31 is poured at the bottom of the pouring trough 21 through concrete, and the solid column 32 slides in the inside of the hollow column 31 with damping. At this time, the protective fence can be completely placed inside the pouring trough 21, which is convenient for subsequent movement and hoisting. After hoisting in place, the balcony can be installed. The positioning groove 11 below facilitates the positioning between the balcony substrate 1 and the building main body 6. The positioning can be completed by making the extension plate 61 at the bottom of the building main body 6 contact with the positioning groove 11. After the balcony is positioned, the steel bars reserved on the building main body 6 and the balcony substrate 1 are tied and welded, and then the grouting mold plate 5 is installed above the area to be poured formed between the two. At this time, the two sides of the inner and outer walls 23 contact the wall surface of the building main body 6, and the bottom of the outer wall 23 contacts Extension plate 61, due to the height difference between the bottom of the inner and outer walls 23, a closed U-shaped casting area is formed between the building body 6 and the balcony substrate 1, and the balcony and the casting trough 21 are cast. Grouting is poured into the casting trough 21 by a grouting machine, and the columns 3 of the protective fence are directly cast inside the side beam 2. The concrete fills the hollow column 31 through the anti-slip groove 311 on the hollow column 31, and the blocks 321 on the solid column 32 are also filled with concrete, making it more difficult to pull out the fence, thereby increasing the stability of the protective fence. Under the influence of gravity, the concrete flows downward into the area to be cast between the balcony substrate 1 and the building body 6, thereby fixing the balcony to the building body 6. The balcony casting and fence installation can be carried out simultaneously, thereby avoiding the waste of resources caused by the secondary installation of the fence and reducing the construction period of the prefabricated building.
