Description

Technical Field

[0001] This utility model belongs to the field of building expansion joint construction technology, and in particular relates to a building expansion joint construction structure. Background Technology

[0002] Building expansion joints are pre-designed gaps or joints within a building structure to accommodate displacement caused by factors such as temperature changes, settlement, shrinkage, or earthquakes. Their function is to prevent structural damage due to internal stress concentration. In construction practice, the structural design of expansion joints and their integration with other systems directly affect the durability, aesthetics, and construction efficiency of a building.

[0003] In existing technologies, building expansion joints are typically designed and constructed according to the structural forms outlined in the national building standard design atlas "14J936 Expansion Joint Construction". The flat roof joint construction within this atlas is widely applicable to horizontal structural elements such as roofs and platforms. The basic approach involves installing protruding concrete retaining walls on both sides of the joint, with an additional waterproof layer and metal cover plate added to the top of the retaining walls, forming a complete waterproof and seepage-resistant structural node. While this traditional construction method achieves the basic functions of expansion joints, it also has a series of limitations, particularly in areas where the building structure meets landscape stone paving, where technical contradictions are especially prominent.

[0004] As modern urban architecture increasingly demands integrated landscape design and aesthetically pleasing interface transitions, the treatment of the interface between the building structure and the external landscape has become a crucial aspect of design and construction. However, traditional expansion joint structures and landscape stone paving systems often lack unified planning; their orientation is typically arranged according to the building axis rather than being flexibly adjusted according to the direction of the landscape stone paving. This rigid setup results in a non-parallel angle between the expansion joint centerline and the paving direction during landscape stone paving. To accommodate this angular deviation, extensive irregular cutting of the paving stones is required during on-site construction, increasing material waste and affecting construction efficiency and the overall harmony of the finished product. Utility Model Content

[0005] The purpose of this utility model is to provide a construction structure for building expansion joints to solve the problem that the direction of expansion joints is difficult to unify with the direction of landscape stone paving, resulting in non-standard cutting of paving materials, large waste of landscape stone, and long construction period.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A construction structure for building expansion joints, wherein a first expansion joint is provided at the roof position of the building; landscape stone is laid on the roof, and the laying direction of the landscape stone is at a first angle to the first expansion joint, the first angle being an acute angle; the construction structure for building expansion joints includes: a correction and splicing assembly, the correction and splicing assembly being disposed on the roof, the correction and splicing assembly including a first splicing component and a second splicing component, the first splicing component and the second splicing component being located on both sides of the first expansion joint; the first splicing component includes a first base and a first countersunk provided on one side of the first base, the second splicing component includes a second base and a second countersunk provided on one side of the second base; a second expansion joint is formed between the first countersunk and the second countersunk, the second expansion joint being parallel to the laying direction of the landscape stone; the first splicing component is provided with a first correction groove connecting the first expansion joint and the second expansion joint, and the second splicing component is provided with a second correction groove connecting the first expansion joint and the second expansion joint.

[0007] In the construction structure for building expansion joints described above, the first angle between the laying direction of the landscape stone and the first expansion joint is 20 to 50 degrees.

[0008] The building expansion joint construction structure described above further includes a waterproof layer, which is provided on the roof and the upper part of the correction assembly. The waterproof layer is recessed and rolled downward from the top of the first and second assemblies at the second expansion joint position, and a waterstop is provided above the waterproof layer within the second expansion joint.

[0009] The building expansion joint construction structure described above further includes an expansion joint cover plate, which is fixed above the first and second assembled parts by bolts, and landscape stone is installed above the expansion joint cover plate.

[0010] The present invention provides a construction structure for building expansion joints as described above. In a further embodiment, the expansion joint cover plate is provided with a stone installation groove, and the landscape stone is installed in the stone installation groove.

[0011] The construction structure for building expansion joints described above further includes a thermal insulation filling layer, which fills the first expansion joint and the second expansion joint, and is located below the waterproof layer.

[0012] The building expansion joint construction structure described above further includes a fire-resistant strip, which is installed inside the first expansion joint and located below the thermal insulation filling layer. The fire-resistant strip is fixedly connected to the concrete of the building by pressure strips and fixing bolts.

[0013] The construction structure for building expansion joints described above is further provided in this utility model, wherein the landscape stone is a square or rectangular structure, and the length of any side of the landscape stone is between 20 cm and 50 cm.

[0014] The beneficial effects of this utility model are: 1. Improve the material utilization rate of landscape stone paving; by setting up the correction and splicing components and making the second expansion joint parallel to the direction of landscape stone paving, a large number of irregular cuts caused by the inconsistency between the expansion joint and the direction of stone paving can be effectively avoided, and the material waste of stone can be significantly reduced.

[0015] 2. Improve construction efficiency and shorten the construction cycle; use standard-sized stone for direct paving, reduce cutting and adjustment work, simplify the construction process, and improve on-site construction efficiency, especially suitable for large-area landscape roof paving projects.

[0016] 3. Aesthetics and structural performance are both taken into account; the expansion joint structure is set in the same direction as the paving, so that the expansion joint is hidden between the stone splices, effectively maintaining the continuity and integrity of the landscape stone paving surface and enhancing the integrated visual effect of the roof landscape.

In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application.

[0022] exist Figure 1 The image illustrates a building with expansion joints. A first expansion joint 30 is located at the roof position. Landscape stone 10 is laid on the roof, with a first included angle (50) between the laying direction 50 and the first expansion joint 30. This first included angle is acute. In a preferred embodiment, the first included angle between the laying direction 50 and the first expansion joint 30 is 20 to 50 degrees. In a specific embodiment, the first included angle is approximately 20 degrees. In a preferred embodiment of the building expansion joint construction structure, the landscape stone 10 is a square or rectangular structure, with any side length between 20 cm and 50 cm. Preferably, the landscape stone 10 is a square structure with a side length of 30 cm. Figure 1In this process, because the width of the landscape stone construction strip is greater than the side length of a single landscape stone, multiple landscape stones need to be laid at intervals along the laying direction. Landscape stones are typically installed in groups of 50° along the laying direction. Since the center line of the first expansion joint forms an angle with the landscape paving direction, material cutting is required during installation, resulting in material loss. The aforementioned landscape stone 10 is preferably made of granite, artificial stone, or other outdoor decorative stone.

[0023] The following combination Figures 1 to 7 This invention describes a construction structure for a building expansion joint according to an embodiment of the present invention, which includes: a correction assembly 20, the correction assembly 20 being disposed above the roof, the correction assembly 20 including a first assembly 21 and a second assembly 22, the first assembly 21 and the second assembly 22 being located on both sides of a first expansion joint 30; The first assembly 21 includes a first base 212 and a first retaining wall 211 disposed on one side of the first base 212; the second assembly 22 includes a second base 222 and a second retaining wall 221 disposed on one side of the second base 222; a second expansion joint 40 is formed between the first retaining wall 211 and the second retaining wall 221, and the second expansion joint 40 is parallel to the laying direction of the landscape stone 10; combined Figure 4 and Figure 5 As shown, the first and second retaining walls are roughly rectangular parallelepipeds, while the first and second bases are roughly truncated triangular pyramids. The heights of the first and second bases are less than the heights of the first and second retaining walls. The space formed above the first base and on the side of the first retaining wall furthest from the second expansion joint is used for installing landscape stone. Landscape stone is installed in the corresponding position of the second assembly.

[0024] The first assembly 21 is provided with a first correction groove 213 connecting the first expansion joint 30 and the second expansion joint 40, and the second assembly 22 is provided with a second correction groove 223 connecting the first expansion joint 30 and the second expansion joint 40. Figures 3 to 5 As shown, the horizontal cross-sections of the first and second correction grooves are approximately triangular.

[0025] The use of the above-mentioned correction and splicing component of this utility model can form a second expansion joint above the first expansion joint by means of the first splicing component and the second splicing component, which is connected to the first expansion joint. Furthermore, landscape stones can be installed sequentially along the laying direction of the landscape stones on the side of the first and second anti-reflective supports away from the second expansion joint. This avoids the problem of large material loss caused by cutting the landscape stones when laying them at the first expansion joint, and can also improve the laying efficiency of the stones accordingly.

[0026] In a preferred embodiment of the building expansion joint construction structure, such as Figure 6 and Figure 7 As shown, it also includes a waterproof layer 35, such as a polymer waterproof membrane, SBS modified bitumen membrane, or polyurethane coating material. The waterproof layer 35 is installed on the roof and the upper part of the corrective assembly. At the second expansion joint 40, the waterproof layer 35 is recessed downwards from the top of the first and second assemblies 21 and 22. A waterstop 34 is installed above the waterproof layer 35 within the second expansion joint 40. The waterproof layer prevents rainwater from seeping into the second and first expansion joints, improving the building's roof waterproofing. The waterstop prevents rainwater from accumulating and seeping into the second expansion joint.

[0027] In a preferred embodiment of the building expansion joint construction structure, such as Figure 6 and Figure 7 As shown, it also includes an expansion joint cover plate 36, which is fixed above the first assembly 21 and the second assembly 22 by bolts. Landscape stone 10 is installed above the expansion joint cover plate 36. The installation of the expansion joint cover plate and the landscape stone prevents the landscape stone on the building roof from being cut at the construction location of the expansion joint, improving the aesthetics and integrity of the landscape stone decoration. In a further preferred embodiment of the building expansion joint construction structure, the expansion joint cover plate 36 is provided with a stone installation groove, and the landscape stone 10 is installed in the stone installation groove. According to the above structure, the landscape stone can be first installed into the stone installation groove of the expansion joint cover plate, and then the assembly of the two can be installed as a whole above the second expansion joint. Furthermore, the landscape stone being in the stone installation groove can prevent it from shaking or shifting during subsequent use.

[0028] In a preferred embodiment of the building expansion joint construction structure, such as Figure 6 and Figure 7 As shown, it also includes an insulation filling layer 31, which fills the first expansion joint 30 and the second expansion joint 40, and is located below the waterproof layer 35. By providing the insulation filling layer, a barrier layer that insulates against heat and cold can be formed within the first and second expansion joints, thereby improving the roof's insulation performance.

[0029] In a preferred embodiment of the building expansion joint construction structure, such as Figure 6 and Figure 7 As shown, it also includes a fire-resistant strip 32, which is installed inside the first expansion joint 30 and located below the thermal insulation filling layer 31. The fire-resistant strip 32 is fixedly connected to the concrete of the building by pressure strips and fixing bolts 33.
