Abstract
Description
Technical Field
[0001] This invention relates to a building, and more particularly to a prefabricated housing unit with a terrace for assembling synthetic buildings, applicable to multi-story or high-rise residential or office buildings. Background Technology
[0002] In existing technologies, terraces in buildings often adopt cantilever structures. The prefabrication design and production of such cantilever structures are difficult. Traditional buildings with terraces are often completed by cast-in-place construction. However, this traditional cast-in-place construction not only involves complicated construction procedures, long construction cycles, and high labor costs, but also makes it difficult to maintain consistent quality. In addition, it generates a lot of construction waste and significant noise and dust pollution, causing great disturbance to the normal lives of surrounding residents. Furthermore, aluminum formwork is prone to deformation after long-term use, and because the aluminum formwork is used to enclose the terrace, the climbing scaffolding will be placed on the outer edge of the site, which is inconvenient for construction and poses certain safety risks.
[0003] Therefore, modern buildings are increasingly adopting precast beams, semi-precast floor slabs, and even precast balconies, precast bathrooms, and precast kitchens to accelerate and simplify the construction process. This construction method does reduce on-site construction work, shortens construction time, and reduces labor. However, buildings with terraces still require cast-in-place concrete structures, or a combination of cast-in-place and precast terraces to connect adjacent units using cast-in-place structures. As a result, the amount of on-site construction work remains large, making it impossible to further shorten the construction period. There is a risk of cracking when secondary casting is performed between precast components and the main building structure. Furthermore, the risk is increased because the terrace is a cantilever structure. Also, since it is not cast in one piece, if the reserved holes in the main building structure are offset, they will not be aligned with the reserved holes in the precast components.
[0004] In some existing prefabricated building units with connecting terraces, the prefabricated terraces are placed on top of the prefabricated building units. Therefore, even if the prefabricated building units and terraces can be prefabricated together in the factory, the total height of the prefabricated building units plus the height of the terrace railings will exceed the limit, causing problems during transportation. Consequently, the railings cannot be pre-installed in the factory and must be installed on-site. Furthermore, this terrace design requires that the indoor and outdoor waterproofing of two adjacent prefabricated building units be done separately, and the connection points are prone to leakage problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a prefabricated building unit with a terrace that can significantly reduce the amount of on-site construction work.
[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to design a prefabricated house unit with a terrace, including a prefabricated house body, which includes walls and a roof slab;
[0007] It also includes: a terrace connected to the main body of the prefabricated house and a steel connecting frame; the terrace includes a terrace base slab and a terrace base beam; the steel connecting frame is partially embedded in the main body of the prefabricated house and partially embedded in the terrace, thereby connecting the main body of the prefabricated house and the terrace together, and the main body of the prefabricated house and the terrace are prefabricated as a whole.
[0008] The steel connecting frame includes: two upright columns, two horizontal members connecting the two upright columns, a longitudinal horizontal member connecting the two horizontal members, and a column connecting member connecting the bottom of the two upright columns.
[0009] The columns and column connecting members are embedded in the wall connecting the prefabricated house body and the terrace, and the horizontal and vertical members are embedded in the bottom beam of the terrace.
[0010] The columns, horizontal members, longitudinal members, and column connecting members adopt a square tube structure.
[0011] The top surfaces of the horizontal and vertical members are welded and fixed with fence connectors.
[0012] The fence connector is a square tube structure, and a gasket is fixed to the bottom surface of the fence connector.
[0013] The prefabricated house has a doorway in the wall connecting to the terrace, and the two columns are respectively set on the left and right sides of the doorway.
[0014] The inner side of the column is welded and fixed with an L-shaped connecting steel bar, which is embedded in the wall of the prefabricated house.
[0015] The two horizontal members on the left and right are welded and fixed with L-shaped angle steel on their opposite sides.
[0016] The terrace is integrally connected to the bottom of the prefabricated house main body.
[0017] The prefabricated house body has a notch at the top on the side connected to the terrace, and a raised step at the bottom of the prefabricated house body perpendicular to the notch. The notches and raised steps of two adjacent prefabricated house bodies cooperate with each other.
[0018] Compared with existing technologies, the prefabricated house unit of the prefabricated building with terrace of the present invention uses a steel connecting frame to connect the prefabricated house body and the terrace together, which solves the problem that the prefabricated house body and the terrace are difficult to prefabricate together. It is convenient to prefabricate both in the factory, thus completely avoiding the disadvantages of the existing connection between terrace and prefabricated house unit, further expanding the prefabrication range, and having an extremely high prefabrication rate. The decoration of the terrace and the prefabricated house body can also be completed in the factory in advance. Moreover, there is no need to seal the aluminum formwork on the construction site, and there is no need to hoist the prefabricated terrace separately. Only the prefabricated house unit needs to be hoisted normally. At the same time, the central area and the side areas of the building can be constructed in parallel. The construction period of a standard floor can be shortened from 6 days in the past when using partial prefabricated units to 4 days, which can shorten the construction period by 33%. Moreover, the construction is more convenient and faster, which can greatly reduce the amount of on-site construction work, make the quality more uniform, reduce labor costs, and minimize the impact of construction on surrounding residents. The terrace is prefabricated at the base of the main prefabricated building on the same floor, allowing for the installation of railings and finishing work to be completed in the factory. This also prevents excessive height issues during transportation, and allows for simultaneous indoor and outdoor waterproofing, avoiding leaks at the junctions between upper and lower prefabricated building units. Furthermore, the construction location shifts from the external scaffolding to the rooftop of the main building's construction floor, significantly reducing safety risks during construction.

[0026] The preferred embodiment shown in the accompanying drawings will be described in further detail below.
[0027] like Figure 1 and Figure 2 As shown, the prefabricated house unit with a terrace of the present invention includes: a prefabricated house body 1 and its connected terrace 2, and a steel connecting frame 3. The prefabricated house body 1 includes walls 11 and a roof slab 12, and may further include an integrally prefabricated main body base slab 13. Alternatively, the main body base slab 13 can be a separate prefabricated slab, which is then connected to the prefabricated house body 1 on-site using cast-in-place reinforced concrete. The terrace 2 includes a terrace base slab 21 and longitudinal and transverse terrace base beams 22. Figure 4 and Figure 5 As shown, the steel connecting frame 3 is partially embedded in the prefabricated house body 1 and partially embedded in the terrace 2, thereby connecting the prefabricated house body 1 and the terrace 2 together. The prefabricated house body 1 and the terrace 2 are prefabricated as a whole in the factory, so the molds and reinforcement of both are designed as a whole.
[0028] like Figure 6 and Figure 7 As shown, the steel connecting frame 3 includes: two left and right uprights 31, two left and right horizontal members 32, a longitudinal horizontal member 33, and an upright connecting member 34. The horizontal members 32 are connected to the outer bottom of the uprights 31, the longitudinal horizontal members 33 are connected at both ends to the outer ends of the two horizontal members 32, and the upright connecting member 34 is connected at both ends to the bottom of the two uprights 31.
[0029] like Figure 3 and Figure 4 As shown, the columns 31 and column connecting members 34 of the steel connecting frame 3 are embedded in the wall 11 connecting the prefabricated house main body 1 and the terrace 2. The horizontal members 32 are embedded in the horizontal terrace bottom beam 22, and the vertical members 33 are embedded in the vertical terrace bottom beam 22. Thus, the steel connecting frame 3 can serve as the main load-bearing component of the prefabricated house main body 1 wall 11 and the terrace 2, firmly connecting the two together.
[0030] In this embodiment, the column 31, the horizontal member 32, the vertical member 33, and the column connecting member 34 can all adopt a square tube structure. Specifically, the column 31 uses a 100×100×6.3mm square tube, the horizontal member 32 and the vertical member 33 use 150×100×6.3mm square tubes, and the column connecting member 34 uses a 70×70×6mm square tube. Of course, different sizes of square tubes can be used depending on the size of the terrace and the stress conditions.
[0031] In addition, several fence connectors 4 are welded and fixed to the top surfaces of the horizontal members 32 and the vertical members 33 for installing the fence 8 during the decoration stage. In this embodiment, the fence connector 4 adopts a 100×100×6.3mm square tube structure, and a gasket 5 is also provided on the bottom surface of the fence connector 4.
[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the prefabricated house body 1 has a doorway 14 on the wall 11 connected to the terrace 2 for installing the terrace door, and the two columns 31 are respectively set on the left and right sides of the doorway 14.
[0033] like Figure 6 As shown, each column 31 has several pairs of vertically symmetrical L-shaped connecting steel bars 6 welded and fixed on its inner side. These L-shaped connecting steel bars 6 are embedded in the wall 11 of the prefabricated house body 1, so that the column 31 can be firmly anchored in the wall 11, preventing the column 31 from being pulled out of the wall 11 due to the load of the terrace 2.
[0034] like Figure 3 and Figure 6 As shown, L-shaped angle steel 7 is welded and fixed to the two horizontal members 32 on opposite sides, which can enhance the horizontal force of the horizontal members 32.
[0035] like Figure 1 and Figure 5 As shown, the terrace 2 is integrally connected to the bottom of the prefabricated house body 1, so that the terrace decoration and the installation of the railing 8 can be completed in the factory without affecting the height of the prefabricated house body 1, and will not cause the phenomenon of excessive height during transportation. Moreover, the waterproofing of the interior and exterior can be completed at one time, avoiding the problem of water leakage at the connection between the upper and lower prefabricated house units.
[0036] The prefabricated house body 1 has a notch 15 on the top of the side connected to the terrace 2, and a raised step 16 on the bottom of the prefabricated house body 1 that is perpendicular to the notch 15. The notches 15 and raised steps 16 of two adjacent prefabricated house bodies 1 fit together, thereby further enhancing the anti-leakage performance at the connection between the upper and lower prefabricated house units.
[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
