Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a bay window. Background Technology

[0002] Currently, the installation of prefabricated bay windows typically involves transporting individual prefabricated components to the construction site and then assembling them. However, due to the inherent physical properties of building materials, different materials have varying coefficients of thermal expansion. During actual use, the ambient temperature of the bay window constantly changes. The prefabricated bay window expands when heated and contracts when cooled, causing significant stress at the joints. This can lead to cracking and detachment of the sealing material at the joints, allowing rainwater to easily seep into the room through the first joint. This not only damages interior decoration materials, such as causing mold on walls and floor deformation, affecting the aesthetics and comfort of the interior, but may also potentially damage the building structure and reduce its durability. Utility Model Content

[0003] The purpose of this utility model is to provide a bay window that solves the technical problem that the joints of prefabricated bay windows are subjected to greater stress due to thermal expansion and contraction, which makes the sealing material at the joints prone to cracking and falling off.

[0004] To achieve the above objectives, this utility model provides a bay window, including a splicing part and multiple prefabricated parts. The multiple prefabricated parts are arranged sequentially in a left-right direction, and a first splicing seam is formed between two adjacent prefabricated parts. The splicing part is provided within the first splicing seam, and two adjacent prefabricated parts are connected through the splicing part. The splicing part includes a pad, mortar, two layers of first sealant, and two splicing rods. The two layers of first sealant are spaced apart along the width direction of the first splicing seam, and the splicing rods are vertically arranged between the two layers of first sealant. The two splicing rods are spaced apart along the width direction of the first splicing seam, the pad is located between the two splicing rods, the mortar fills the space between the two layers of first sealant, and the splicing rods are made of elastic sealing material.

[0005] Optionally, the prefabricated part includes two prefabricated parts, which are symmetrically arranged. Each prefabricated part includes a front window and a rear window. The rear window is located on the rear side of the front window to form an L-shaped structure. The rear window is located at the end of the front window away from the other prefabricated part, and the first splicing seam is formed between the front window parts of the two prefabricated parts.

[0006] Optionally, a second seam is formed between the front window and the rear window, and a splicing part is provided in the second seam, through which the front window and the rear window are connected.

[0007] Optionally, the front window portion is provided with a split window that extends through the front and rear directions, and the split window extends through to the side of the front window portion relative to the left and right directions in the direction of another prefabricated portion, and the split windows of the two front windows portions are connected.

[0008] Optionally, the rear side of the front window and the side of the rear window relative to the other prefabricated part are provided with a waterproof layer.

[0009] Optionally, it may also include a plurality of embedded reinforcing bars, which are spaced apart in the precast part, with one end of each embedded reinforcing bar embedded in the precast part and the other end extending out of the front side of the precast part.

[0010] Optionally, the end of the embedded reinforcing bar away from the precast part is provided with a bent portion.

[0013] Optionally, the thickness of the splicing rod is equal to the thickness of the first sealant.

[0014] Optionally, a second sealant is also included, with the second sealant provided at the top and bottom edges of each of the prefabricated portions.

[0015] Compared with the prior art, the bay window implemented in this utility model has the following advantages:

[0016] In this utility model of a bay window, multiple prefabricated components are manufactured in the workshop and then transported to the construction site for installation and assembly. Two prefabricated components are joined together by a splicing joint. Specifically, the splicing joint is located within the first joint formed between the two prefabricated components. Two layers of first sealant are spaced apart along the width of the joint to fill both sides of the joint and prevent rainwater, air, and dust from seeping into the interior of the bay window, thus protecting its internal structure. Furthermore, two splicing rods are spaced apart between the two layers of first sealant along the width of the joint to fill the depth of the joint and facilitate control over the depth and thickness of the sealant application. These rods also absorb deformation, i.e., their elasticity cushions the prefabricated components due to thermal expansion and contraction. The change in gap width caused by thermal expansion and contraction reduces the stress on the first sealant. Furthermore, the pad is placed between the two splicing rods to control the width of the splice joint and ensure that the components are relatively aligned, facilitating subsequent material construction. It can also provide additional connection strength, disperse the stress between components, and prevent deformation at the splice. Furthermore, mortar is filled between the two layers of the first sealant to fill the bottom of the splice joint and the gaps between the components, enhancing the rigidity and load-bearing capacity of the splice and providing a stable base for the splicing rods, sealant, and pad. In summary, the components of the bay window of this utility model can buffer the change in gap width caused by thermal expansion and contraction through the elasticity of the splicing rods, thereby reducing or avoiding cracking and detachment of the sealing material at the splice.

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] like Figures 1 to 4 As shown, a bay window of this utility model includes a splicing part 2 and multiple prefabricated parts 1. The multiple prefabricated parts 1 are arranged sequentially in the left-right direction. A first splicing seam is formed between two adjacent prefabricated parts 1. The splicing part 2 is provided in the first splicing seam. Two adjacent prefabricated parts 1 are connected through the splicing part 2. The splicing part 2 includes a pad 21, mortar 23, two layers of first sealant 22 and two splicing rods 24. The two layers of first sealant 22 are spaced apart along the width direction of the first splicing seam. The splicing rods 24 are vertically arranged between the two layers of first sealant 22. The two splicing rods 24 are spaced apart along the width direction of the first splicing seam. The pad 21 is arranged between the two splicing rods 24. The mortar 23 fills the space between the two layers of first sealant 22. The splicing rods 24 are made of elastic sealing material.

[0026] In the above technical solution, multiple prefabricated parts 1 are manufactured in the workshop and then transported to the construction site for installation and assembly. Two prefabricated parts 1 are joined together by a splicing part 2. Specifically, the splicing part 2 is set in the first splice joint formed between two prefabricated parts 1. The two layers of first sealant 22 of the splicing part 2 are spaced apart along the width of the splice joint to fill the two sides of the splice joint and prevent rainwater, air, and dust from seeping into the interior of the bay window from the splice joint, thus protecting the internal structure of the bay window. Furthermore, two splicing rods 24 are spaced apart between the two layers of first sealant 22 along the width of the splice joint to fill the depth of the splice joint and facilitate control of the application depth and thickness of the sealant. They can also absorb deformation, that is, buffer the prefabricated parts 1 caused by thermal expansion and contraction through their own elasticity. The variation in gap width reduces the stress on the first sealant 22. Furthermore, the pad 21 is placed between the two splicing rods 24 to control the width of the splice joint and ensure that the components are relatively aligned, facilitating subsequent material construction. It can also provide additional connection strength, disperse the stress between components, and prevent deformation at the splice. Furthermore, mortar 23 is filled between the two layers of first sealant 22 to fill the bottom of the splice joint and the gaps between components, enhancing the rigidity and load-bearing capacity of the splice and providing a stable base for the splicing rods 24, sealant, and pad 21. In summary, the components of the bay window of this utility model can buffer the changes in gap width caused by thermal expansion and contraction through the elasticity of the splicing rods 24, thereby reducing or avoiding cracking and detachment of the sealing material at the splice.

[0027] The splicing rod 24 is made of a material with good elastic deformation and good sealing performance, such as PE, FRP, Invar alloy, EPDM, neoprene rubber, polyurethane, silicone sealant, titanium alloy, XPS and rock wool composite material; in addition, the mortar 23 is preferably thermal insulation mortar 23.

[0028] Additionally, the first sealant 22 can fill the opening of the joint.

[0029] Furthermore, the system includes two prefabricated sections 1, which are symmetrically arranged. Each prefabricated section 1 includes a front window section 11 and a rear window section 12. The rear window section 12 is located on the rear side of the front window section 11, forming an L-shaped structure. The rear window section 12 is located at the end of the front window section 11 away from the other prefabricated section 1. The first splicing seam is formed between the front window sections 11 of the two prefabricated sections 1. The two prefabricated sections 1 form a "U"-shaped structure. Furthermore, the symmetrical arrangement of the two prefabricated sections 1 facilitates standardized production and modular installation, reduces on-site construction errors, and improves installation efficiency. The L-shape formed by the front window section 11 and the rear window section 12 can expand the interior space and enhance structural stability.

[0030] Furthermore, a second splicing seam is formed between the front window portion 11 and the rear window portion 12, and a splicing part 2 is provided in the second splicing seam. The front window portion 11 and the rear window portion 12 are connected through the splicing part 2, so that the front window portion 11 and the rear window portion 12 are manufactured separately before transportation and then spliced ​​together at the construction site, saving transportation difficulty and transportation costs.

[0031] Furthermore, the front window portion 11 is provided with a sub-window 111 that extends through the front and rear directions. The sub-window 111 extends through the other prefabricated portion 1 to the side of the front window portion 11 relative to the left and right directions. The sub-windows 111 of the two front window portions 11 are connected and the two sub-windows 111 form a complete window. The shape of the sub-window 111 is rectangular, and the two sub-windows 111 form a rectangular window.

[0032] Furthermore, the rear side of the front window 11 and the rear window 12 are provided with a waterproof layer 3 relative to the other prefabricated part 1 to fill the capillaries and tiny cracks on the prefabricated part 1, block moisture from seeping into the inside of the bay window through the seams, form a seamless waterproof membrane, and prevent water vapor from intruding along the weak parts.

[0033] Furthermore, it also includes a plurality of embedded reinforcing bars 5, which are spaced apart from each other in the prefabricated part 1. One end of each embedded reinforcing bar 5 is embedded in the prefabricated part 1 and the other end extends out of the front side of the prefabricated part 1. The end of the embedded reinforcing bar 5 away from the prefabricated part 1 is used to embed into the cast-in-place building component located in front of it. The embedded reinforcing bars 5 are used to connect the prefabricated part 1 and the cast-in-place building component. The cast-in-place building component is manufactured after the embedded reinforcing bars 5 are installed and spliced.

[0034] Furthermore, the end of the embedded steel bar 5 away from the precast part 1 is provided with a bent part 51, which forms an L-shaped structure to enhance the connection strength between the embedded steel bar 5 and the cast-in-place building component and to provide a lifting point for the precast part 1.

[0035] Furthermore, each of the embedded steel bars 5 forms at least two groups of first steel bars 6, the two groups of first steel bars 6 are spaced apart in the vertical direction, the first steel bar group 6 includes a plurality of embedded steel bars 5 spaced apart in the horizontal direction, and the bent portion 51 of the embedded steel bars 5 in the first steel bar group 6 is bent away from or close to the other group of first steel bars 6.

Each group of second steel bars 7 includes a plurality of embedded steel bars 5 spaced apart in the up-down direction. The bent portion 51 of the embedded steel bars 5 in the second group of second steel bars 7 is bent away from or closer to the other group of second steel bars 7.

[0037] Among them, the two sets of steel bars are used to connect the building components on both sides. Specifically, the first set of steel bars 6 can be used to connect the cast-in-place beam, and the second set of steel bars 7 can be used to connect the cast-in-place column. The bent parts 51 of the two sets of steel bars are bent in opposite directions to facilitate lifting from all directions.

[0038] Furthermore, the thickness of the splicing rod 24 is equal to that of the first sealant 22 to improve the cushioning effect of the splicing rod 24.

[0039] Furthermore, a second sealant 4 is also included, with the top and bottom edges of each of the prefabricated parts 1 provided with the second sealant 4 to prevent rainwater, air and dust from penetrating from the top and bottom of the prefabricated parts 1 into the inside of the bay window.

[0040] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0041] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

Two layers of first sealant 22 are spaced apart along the width of the splicing seam to fill the two sides of the seam and prevent rainwater, air, and dust from seeping into the interior of the bay window, thus protecting the internal structure of the bay window. Furthermore, two splicing rods 24 are spaced apart between the two layers of first sealant 22 along the width of the splicing seam to fill the depth of the seam and facilitate control of the sealant application depth and thickness. They also absorb deformation, i.e., their elasticity buffers the expansion and contraction of the prefabricated parts 1 caused by thermal expansion and contraction. The change in gap width reduces the stress on the first sealant 22. Furthermore, the pad 21 is placed between the two splicing rods 24 to control the width of the splice joint and ensure that the components are relatively aligned, which facilitates subsequent material construction. It can also provide additional connection strength, disperse the stress between components, and prevent deformation at the splice.
