Description

Technical Field

[0001] The present invention relates to the technical field of building bay windows, and in particular to a building energy-saving bay window, a building construction device and a construction method thereof. Background Art

[0002] Bay windows, typically rectangular or trapezoidal in shape, project toward the exterior. They not only enhance a home's natural light and ventilation, but also add architectural appeal to the exterior of commercial housing. Prefabricated bay windows can incorporate energy-efficient technologies, such as thermally-insulated aluminum profiles and triple-glazed, double-chambered glass, significantly reducing the heat transfer coefficient to below 2.0 W / (m²·K). Prefabrication ensures precise quality control, avoiding thermal bridges caused by on-site construction errors. As part of prefabricated construction, prefabricated bay windows align with the development of green buildings.

[0003] In traditional construction, the bay windows are generally cast and formed at the same time as the main body of the building. However, this can easily lead to large errors in the size of the bay windows, uneven quality, and even quality risks, and the construction is relatively cumbersome. Existing prefabricated bay windows need to be reinforced and installed after they are connected to the main body of the building and cast. Generally, workers need to use hanging baskets for reinforcement construction, and set supporting templates on the outside of the building wall to support the bay windows. This not only increases the risk of disassembly and assembly operations for construction workers, but also prolongs the overall construction time of the bay windows. Summary of the Invention

[0014] The present invention also discloses a method for using a building construction device for energy-saving bay windows, comprising the following steps: S1: Pre-positioning of the bay window body: The first connecting steel bar of the bay window body is bent slightly lower than the U-shaped steel bar in the casting cavity of the building body, and the bay window body is moved horizontally so that the first connecting steel bar is under the U-shaped steel bar; Lift the bay window body upwards so that the bent portion of the first connecting steel bar interlocks with the U-shaped steel bar to form an anti-falling structure, and align the positioning block with the positioning slot at the same time; Continue to push the bay window body until the mounting frame is tightly in contact with the outer side of the building body; S2: Installation of construction equipment: Place the fixing rod of the L-shaped support close to the inner wall of the building body, and fix the base to the bottom floor with anchor bolts; S3: Hydraulic system driven support: Start the hydraulic cylinder, and the piston rod pushes the slide to slide along the swing rod, driving the swing rod to rotate with the hinge point as the center of the circle, so that the abutment plate presses against the inner top wall of the window, sharing the load on the positioning block; The hydraulic cylinder continues to advance, and the slide moves toward the main body of the building through the steel wire rope pulling the slide rod. The slide rod pushes the block seat to slide along the connecting plate through the movable rod, so that the distance between the two block seats is expanded to exceed the width of the window. The steel wire rope continuously pulls and compresses the elastic telescopic rod, causing the block to push the window tightly, forcing the mounting frame to fit completely with the outer side of the building body; S4: Concrete pouring and curing: Concrete is poured into the pouring cavity of the building main body. The concrete flows through the pouring cavity into the pouring groove of the bay window body and wraps around the first connecting steel bar and the second connecting steel bar. After the concrete solidifies, the bay window body is structurally anchored to the building main body through the connecting steel bars. S5: Device disassembly: Retract the piston rod of the hydraulic cylinder to release the thrust of the block seat on the window and the supporting force of the abutment plate, remove the anchor bolts, and move away the L-shaped support and construction device.

[0015] Compared with the prior art, the present invention provides a building energy-saving bay window and a building construction device and a construction method thereof, which have the following beneficial effects: 1. The energy-saving bay window of this building, its building construction device and its construction method, solve the large dimensional error, thermal bridge problem and quality hidden danger caused by on-site casting by adopting prefabricated assembled bay windows. The positioning plugs and slots are combined with the U-shaped steel bar anti-slip structure to improve the installation stability of the bay window and effectively prevent the bay window from falling off. At the same time, the prefabricated bay window, as part of the assembled building, is in line with the development direction of green buildings.

[0016] 2. The energy-saving bay window and its building construction device and method provide vertical support force to the abutment plate by rotating the swing rod, thereby reducing the shear force on the positioning plug. At the same time, the expansion of the stop seat generates a continuous lateral thrust after the elastic telescopic rod is compressed, forming a double support for the bay window body, thereby improving the installation stability and work efficiency of the bay window.

[0017] 3. The energy-saving bay window of the building, its building construction device and its construction method are designed so that the distance between the two blocks on the connecting plate is initially smaller than the size of the window body, so that the pushing part can smoothly move from the inside of the building body to the outside of the bay window body. As the steel wire rope pulls the sliding rod, the sliding rod moves toward the building body and pushes the block seat to slide on the connecting plate through the movable rod, so that the distance between the two blocks is larger than the size of the window, so that the subsequent block seat can abut and push the window, thereby ensuring the orderly operation of the positioning mechanism.

[0018] 4. The energy-saving bay window and its building construction device and construction method form a double-slope drainage channel by setting a diversion slope and a diversion seat, which effectively prevents rainwater from seeping into the joint between the bay window body and the main body of the building, thereby improving the waterproof life.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, this embodiment proposes a building energy-saving bay window, including a bay window body 2 arranged on the outside of a building main body 1, the bay window body 2 including: a mounting frame 201, a window body 202 and a positioning plug 4, which abuts against the building main body 1 and is provided with a casting trough 3 connected to the casting cavity 101 of the building main body 1, wherein a first connecting steel bar 301 and a second connecting steel bar 302 are fixed in the casting trough 3; a positioning frame 203 for installing the energy-saving window is provided on the mounting frame 201, and is fixed on the mounting frame 201 and matched with a positioning slot 401 on the building main body 1; wherein the casting trough 3 is structurally anchored to the building main body 1 through the first connecting steel bar 301 and the second connecting steel bar 302, and the positioning plug 4 and the positioning slot 401 realize prefabricated assembly positioning; Furthermore, the first connecting steel bar 301 and the second connecting steel bar 302 extend from one end of the casting trough 3 into the casting cavity 101. The protruding end of the first connecting steel bar 301 is provided with a bent portion, and a U-shaped steel bar 1011 matching the bent portion is provided in the casting cavity 101. The bay window body 2 is precisely positioned through the mechanical cooperation of the positioning plug 4 and the positioning slot 401 pre-buried in the building body 1. The abutment surface between the mounting frame 201 and the building body 1 is filled with EPDM sealing strips to ensure airtightness. The first connecting steel bars 301 and the second connecting steel bars 302 set in the casting trough 3 extend to the casting cavity 101 of the building body 1, forming a bidirectional tensile anchoring node with a pull-out resistance of ≥15kN through cast-in-place concrete. The positioning frame 203 is pre-buried in the inner side of the window body 202 using a thermally-insulated aluminum profile, supporting the rapid installation of triple-glazed, double-cavity energy-saving windows. During pre-installation, the bay window body 2 is hoisted to the outside of the building body 1, with the bent portion of the first connecting steel bar 301 lower than the U-shaped steel bar 1011.

The positioning inserts 4 are then aligned with the positioning slots 401. The mounting frame 201 is then brought into contact with the outer side of the building body 1. C30 slightly expansive concrete is poured from the casting cavity 101 of the building body 1, and the casting trough 3 is naturally filled through the casting cavity 101. This prefabrication and assembly process reduces the bay window installation time to 1.5 hours, which is 60% more efficient than the traditional cast-in-place method.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 9 As shown, as a preferred embodiment, based on the above-mentioned method, this embodiment proposes a building construction device for energy-saving bay windows, including an L-shaped support 5 arranged on the bottom floor 102 of the building body 1, and also including: a swing rod 6 and a hydraulic cylinder 7, one end of the swing rod 6 is rotatably connected to the L-shaped support 5 through a first pin shaft, and the other end is connected to an abutment plate 601 that is movably against the window body 202 through a second pin shaft, and the second pin shaft is provided with a torsion spring for driving the abutment plate 601 to reset; the hydraulic cylinder 7 is movably provided with a Placed on the lower side of the L-shaped support 5, the piston rod of the hydraulic cylinder 7 is connected to the slide 701, and the slide 701 is slidably connected to the swing rod 6.

[0027] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 9As shown, as a preferred embodiment, on the basis of the above method, further, the L-shaped support 5 includes an L-shaped support rod 501, a base 502 arranged at the bottom of the L-shaped support rod 501 and a fixing rod 503 arranged perpendicular to the L-shaped support rod 501, the fixing rod 503 is movably abutted against the inner wall of the building body 1, the bottom of the hydraulic cylinder 7 is rotatably connected to the base 502 through a pin shaft, and an anchor bolt 5021 is provided between the base 502 and the bottom floor 102; when installing the construction device, first make the fixing rod 503 of the L-shaped support 5 close to the inner wall of the building body 1, and then fix the base 502 at the corresponding bottom floor 102 position at this time by the anchor bolt 5021 to ensure that the fixing rod 503 is in abutment with the inner wall of the building body 1.

The slide rod 802 pushes the stopper 801 to slide along the connecting plate 8 via the movable rod 804, so that the distance between the two stoppers 801 is expanded to exceed the width of the window 202. The steel wire rope 902 is continuously pulled, compressing the elastic telescopic rod 504 so that the stopper 801 pushes the window 202 tightly, forcing the mounting frame 201 to completely fit the outer side of the building body 1; S4: Concrete pouring and curing: Concrete is poured into the pouring cavity 101 of the building body 1. The concrete flows through the pouring cavity 101 into the pouring groove 3 of the bay window body 2, wrapping the first connecting steel bar 301 and the second connecting steel bar 302. After the concrete solidifies, the bay window body 2 is structurally anchored to the building body 1 through the connecting steel bars.
