Description

Technical Field

[0001] This application relates to a multifunctional integrated device for renovating existing buildings, belonging to the field of existing building renovation technology. Background Technology

[0002] Older buildings generally refer to those built before 2000. Their windows are often covered by single-pane glass, resulting in generally poor thermal and sound insulation performance. Furthermore, due to a lack of pre-planned space during construction, the introduction of air conditioning and other facilities has led to various problems on the exterior facades, such as haphazardly hung air conditioner units, security windows resembling birdcages, and randomly placed flowerpot stands, making the facades appear cluttered and unsightly. Additionally, the aging electrical wiring in older buildings increases the risk of fire, while inadequate fire safety facilities greatly increase the likelihood of casualties in the event of a fire.

[0003] In current renovations of old buildings, the common approach is to remove the old exterior windows and replace them with new double-glazed windows, cover the outdoor air conditioning units with aluminum grilles, replace protruding security bars on the exterior windows with those flush against the outside, and add acrylic canopies along the top of the windows. While these measures represent an improvement over the original old buildings, they still have shortcomings:

[0004] (1) The components introduced during the renovation of the exterior wall are independent and lack integrity and coordination on the facade, resulting in poor aesthetics and low utilization of the exterior wall space.

[0005] (2) The renovation requires the removal of the original windows, which affects the normal life and work of the owners. The work cycle is long and the workload is large.

[0006] (3) The fire protection facilities in old buildings are generally insufficient and relatively impossible to improve. In the event of an emergency, they cannot provide residents with enough safe escape routes. Utility Model Content

[0007] In view of this, this application provides a multifunctional integrated device for renovating existing buildings, which not only meets the requirements of comfort and aesthetics in the use of existing buildings, especially old buildings, but also improves the efficiency of renovation and endows the building with multifunctionality.

[0008] Specifically, this application is implemented through the following scheme:

[0009] A multifunctional integrated device for renovating existing buildings is installed on the outer side of the building's exterior wall, which has window openings. The multifunctional integrated device includes a main steel frame, an exterior window, and an enclosure mechanism. The main steel frame is fixed above the window opening and its surface is coated with fluorocarbon paint. The exterior window and the enclosure mechanism are fixedly connected to the main steel frame. The exterior window is fitted to the outer perimeter of the window opening and includes a PVC-U plastic frame and glass installed inside the frame. The enclosure mechanism is located below the exterior window and forms an accommodating space between itself and the exterior wall. This space can be used to place items such as flower pots and outdoor air conditioning units, or it can be used as a backup space for escape and refuge.

[0010] The introduction of the multi-functional integrated device used in the above-mentioned renovation, the connection between the main steel frame and the existing building, forms the connection basis of this application. The exterior windows, together with the original window openings and the original exterior windows installed on them, achieve the effects of energy saving and sound insulation. The enclosure structure gives the existing building, including old buildings, the characteristics of safety, aesthetics, and additional reserved space. The main steel frame, exterior windows, and enclosure structure work together to achieve the rational arrangement of many functional units on the exterior wall.

[0011] Furthermore, as a preferred option:

[0012] The main steel frame includes at least two horizontal joists and several vertical joists. The horizontal joists are fixed to the exterior walls on the upper and lower sides of the window opening, and the vertical joists are fixed to the horizontal joists. More preferably, at two adjacent window openings, the horizontal joists include an upper horizontal joist, a middle horizontal joist, and a lower horizontal joist. The vertical joists and horizontal joists are fixedly connected to form a U-shaped main steel frame: the upper and middle horizontal joists are fixed to the upper and lower edges of the upper window opening, respectively, and the lower horizontal joist is fixed to the upper edge of the lower window opening; or, the upper horizontal joist is fixed to the lower edge of the upper window opening, and the middle and lower horizontal joists are fixed to the upper and lower edges of the lower window opening, respectively.

[0013] The inner side of the outer window is equipped with a sliding rail, on which a detachable guardrail is installed for use as a burglarproof window.

[0014] The enclosure structure includes a steel frame, a grid, and a base plate. The steel frame is welded to the two sides of the main steel frame facing the outer wall. The grid consists of four parts: a portion distributed on the top surface of the steel frame, a portion located on the left side of the steel frame, a portion located on the front side of the steel frame, and a portion located on the right side of the steel frame. The base plate and the steel frame are connected to the main steel frame, with the base plate located at the bottom of the steel frame. The base plate, the steel frame, the grid, and the corresponding outer wall form the accommodating space. Preferably:

[0015] A second grid is provided on the base plate, and a pad is placed between the base plate and the second grid to create a gap between them. A stop is placed between the second grid and the steel frame to prevent the second grid from sliding. Preferably, both the base plate and the second grid can be assembled from multiple structural units.

[0016] Of the four parts of the first grid, the portion located on the top surface of the steel frame is movably connected to the steel frame. More preferably, it also includes a third grid, which is connected to the steel frame and located above the first grid.

[0017] The three grilles mentioned above each serve a different function:

[0018] The grille can be fixed to the corresponding positions on the left, front, right and top of the steel frame using stainless steel screws. The grilles on the left, front and right sides enclose the steel frame and form a relatively fixed accommodating space, while the grille on the top surface is connected to the steel frame in a movable manner, making it convenient to open and install equipment such as air conditioner outdoor units.

[0019] The third grid installed above the first grid on the top surface can not only share the load-bearing capacity of the top of the first grid, but also expand the area above the first grid without affecting the stress on the steel frame, so that lightweight items such as potted plants can be placed.

[0020] The second grid is installed above the base plate, forming an escape route in conjunction with the base plate. Especially when multiple structural units are used for assembly, different numbers of structural units can be removed or broken as needed to achieve emergency escape.

[0021] If the window opening is larger than 2.4 (width) * 1.8 (height) m, the outer window is equipped with a steel lining; if it is less than 2.4 * 1.8 m, then a steel lining is not required.

[0022] The aforementioned multi-functional integrated device also includes safety equipment such as safety ropes and safety hammers. The safety ropes are made of steel wire core nylon ropes and can be tied to the main steel frame at the position corresponding to the outer window for easy access. The safety hammers can be placed in the storage space.

[0023] The beneficial effects of this application function are as follows:

[0024] 1. Multiple functions are integrated into one unit, and on-site assembly and construction are highly efficient. The new exterior windows are set on the outside of the window opening without removing the original windows, and without damaging the original interior decoration of the building. Moreover, there is a certain gap between the new PVC exterior windows and the original windows, which not only enhances the room's heat preservation effect and achieves energy saving, but also improves the sound insulation performance.

[0025] 2. In addition to providing shade, placing flower pots, and shielding air conditioner outdoor units, due to the significant fire hazards in old buildings, in the event of a fire or obstruction of escape routes, people can be secured with safety ropes, lift one section of the aluminum grille through the window, and enter the space formed by the main steel frame and the enclosure components for temporary refuge. Depending on the degree of danger, a safety hammer can be used to break one of the glass bottom plates and lift the corresponding section of the aluminum grille to escape to the next floor.

[0026] 3. The anti-theft railing is installed on the inner sliding track of the exterior window, which avoids a cluttered facade. Attached Figure Description

[0038] In addition, the terms "first" and "second" are only for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "plural" is two or more, unless otherwise specifically and clearly defined.

[0039] This embodiment provides a multifunctional integrated device for retrofitting existing buildings. The embodiments of this application will be described below in conjunction with the accompanying drawings.

[0040] Refer to Figure 1 , Figure 1 which shows the multifunctional integrated device of this embodiment, including a main steel frame 1, an external window 2 and an enclosure mechanism 3.

[0041] As a specific case:

[0042] Combined with Figure 2 , Figure 3 : The main steel frame 1 includes an upper horizontal keel 11, a middle horizontal keel 12, a lower horizontal keel 13 and vertical keels 14. The upper horizontal keel 11, the middle horizontal keel 12 and the lower horizontal keel 13 are parallel to each other and distributed at different heights. Two vertical keels 14 are provided. The upper horizontal keel 11, the middle horizontal keel 12, the lower horizontal keel 13 and the vertical keels 14 form a main steel frame 1 in the shape of a Chinese character "ri". Among them, the upper horizontal keel 11 and the middle horizontal keel 12 are respectively parallel to the upper edge and the lower edge of the outer side of the base of the upper window opening 6 of the old building and retreat 50 mm outward; the lower horizontal keel 13 is parallel to the upper edge of the outer side of the lower window opening and retreats 50 mm outward, and the two vertical keels 14 are parallel to the left and right sides of the outer side of the window opening and retreats 50 mm outward. The cross-sectional dimensions of the above-mentioned horizontal and vertical keels are all 80 mm × 80 mm, and the wall thickness is not less than 6 mm. The outward retreat reserves the frame thickness of the external window 2.

[0043] Window 2 is a double-glazed sliding window (sliding direction as follows) Figure 2 As indicated by the horizontal arrow, the frame includes a frame and glass. The frame is made of PVC-U plastic, and the material used meets the relevant requirements of GB / T8814-2017 "Unplasticized Polyvinyl Chloride (PVC-U) Profiles for Doors and Windows". It is embedded and fixed to the upper part of the main steel frame 1, and the frame is aligned and tightly attached to the outer edge of the base layer of the old building window opening 6. Double-glazed insulated glass is installed inside the frame. A sliding rail can be installed on the inner side of the frame, and a removable guardrail 21 can be installed on the sliding rail as a burglarproof window as needed.

[0044] Taking the most common sliding window in the renovation of old buildings as an example, the frame of the outer window 2 is made of plastic, which has a good heat insulation effect. The frame generally does not need to be reinforced with steel. If the size of the window opening is greater than 2.4m (width) * 1.8m (height), the cross-sectional size of the frame can be increased and a steel reinforcement can be added inside the frame.

[0045] The enclosure structure 3 is located below the exterior window 2 and forms a space between it and the exterior wall. It can be used to place items such as flower pots and outdoor air conditioning units, or as a backup space for escape and refuge.

[0046] Enclosure component 3 includes grid one 31, grid two 32, grid three 33, steel frame 34, and base plate 35, combined with Figures 3 to 6 The steel frame 34 has a steel pipe cross-section of 80mm × 80mm and a side width of 700mm. The steel frame 34 is welded to the left and right longitudinal keels 14 at the lower part of the main steel frame 1. Grille 1 31 is fixed to the left, front, right, and top surfaces of the steel frame 34 using M5 stainless steel screws. Grille 33 rests on a continuous angle steel welded to the central transverse keel 12 and on the upper surface of the steel frame 34. The base plate 35 is a glass base plate, fixed to the lower transverse keel 13 and the upper surface of the steel frame 34. Grille 2 32 rests on the main steel frame 1 and the upper surface of the base plate 35 via pads 36, leaving a gap of approximately 20mm between it and the base plate 35. Stoppers 37 are installed on the outer sides of the base plate and grille 2 32 to prevent slippage. All of the above grilles can be made of aluminum.

[0047] The clear spacing of grille 1 (31) is no greater than 110mm, the distance between its bottom and the steel frame is approximately 150mm, and the wall thickness is no less than 1.8mm. Grille 3 (33) has a clear spacing of approximately 80mm, a wall thickness of no less than 1.8mm, and a grille thickness of no less than 30mm. It is divided into several segments along the length of the enclosure structure 3, each segment being no greater than 600mm. The base plate 35 is made of 6mm thick tempered glass with a frosted finish facing downwards. It is also divided into several segments along the length of the enclosure structure 3, each segment being no greater than 600mm. Grille 2 (32) has a clear spacing of approximately 80mm, a wall thickness of no less than 1.8mm, and a grille thickness of no less than 30mm. It is divided into corresponding segments to the base plate 35.

[0048] If there is an outdoor air conditioning unit, it can be fixed to the outer wall inside the enclosure 3 with a special bracket, and placed as close to the side as possible, so as to leave a certain space inside the enclosure 3 for people to stay in case of emergency.

[0049] Taking the standard floor window opening in an old building as an example, in practical applications, the main steel frame 1 is continuously welded between each floor vertically, and the size of the enclosure mechanism 3 can be appropriately enlarged in the length direction according to actual needs. All steel components are treated with rust prevention and fire prevention.

[0050] This device can also be equipped with safety equipment, such as a safety rope 41 and a safety hammer 42. The safety rope 41 is a steel wire core nylon rope with a length of not less than 4 meters, and is tied to the longitudinal keel 14 of the main steel frame 1. The safety hammer 42 is placed on the second grille 32 and is ensured to be able to break the bottom plate 35. Old buildings are generally older, with aging electrical wiring, which is prone to fire and lacks fire-fighting facilities. In the event of a fire or obstruction of escape routes, people can tie on the safety rope 41, go through the window, lift one of the aluminum grilles 33, and enter the accommodation space formed by the main steel frame 1 and the enclosure mechanism 3 for temporary refuge. Depending on the degree of danger, the safety hammer 42 can be used to break one of the bottom plates 35 and lift the corresponding grille 32 to escape to the next floor.

[0051] The above-mentioned device is used in existing buildings, combined with Figure 7 The main steel frame 1 is connected to the exterior wall of the existing building, forming the foundation for the installation and connection of this application. The exterior window 2, together with the original window opening and the original exterior window installed on it, achieves the effects of energy saving and sound insulation. The enclosure structure 3 gives the existing building, including old buildings, the characteristics of safety, aesthetics, and additional reserved space. The main steel frame 1, exterior window 2, and enclosure structure 3 work together to realize the rational arrangement of many functional units on the exterior wall.

[0052] The device of this application can be introduced using the following process:

[0053] Step 1: Measure the dimensions of the existing old door and window openings, subtract the thickness of the plaster layer, and obtain the dimensions of the window openings 6 on the basic wall 5.

[0054] Step 2: Based on the obtained window opening dimensions, the main steel frame 1, the exterior window 2, and the enclosure components 3 are prefabricated in the factory.

[0055] Step 3: Remove the plaster layer from the wall around the old door and window openings to expose the foundation wall 5 and structural beam 51, and insert chemical bolts 8, post-embedded plates and connectors 7 at the corresponding positions of the structural beam 51.

[0056] Step 4: After welding the prefabricated main steel frame 1 to the rear embedded plate and connector 7, the main steel frame 1 is hot-dip galvanized and coated with fluorocarbon paint, so that the main steel frame 1 is fixed to the structural beam above the window opening; the outer window 2 is embedded and fixed to the main steel frame 1, and closely attached to the outer wall of the window opening 6, and the installation gap is sealed with silicone construction adhesive.

[0057] Step 5: Securely connect the enclosure mechanism 3 to the main steel frame 1 to complete the modification.

[0058] The above-described embodiments are merely illustrative of several feasible implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention, nor are the embodiments intended to limit the scope of protection in the claims of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention. All equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
