Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to an integrally pre-embedded expansion joint structure for a roof. Background Art

[0002] With the rapid development of the construction industry, the building volume is getting larger and larger, and the construction area of the ground or roof is gradually expanding. When the roof building area is relatively large, it is necessary to set expansion joints according to the actual situation of the building. The expansion joint is a structural joint set at an appropriate part along the construction joint direction of the building or structure to prevent cracks or damage to building components due to climate temperature changes (thermal expansion and cold contraction). The existing roof expansion joint structures are prone to water leakage, which is very difficult to repair later, often causing huge economic losses, and once quality problems occur, maintenance is extremely difficult.

[0003] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0009] A rubber plate is vertically and movably arranged in the two expansion joints. An upper flange for sealing the upper joint of the expansion joint is formed by extending the top of the rubber plate. A lower flange for sealing the lower joint of the expansion joint is formed by extending the bottom of the rubber plate. Pulling flanges are respectively formed on the opposite sides of the rubber plate, and the clamping joint is clamped between the pulling flanges. A plurality of upper rib plates are formed on the upper part of the rubber plate, and the upper rib plates are connected between the upper flange, the upper part of the vertical side plate and the upper part of the pulling flange. A plurality of lower rib plates are formed on the lower part of the rubber plate, and the lower rib plates are connected between the lower flange, the lower part of the vertical side plate and the lower part of the pulling flange.

[0010] Further, the opposite sides of the rubber plate are respectively arranged at intervals with the two vertical side plates.

[0011] Further, the plurality of upper rib plates are arranged at intervals along the length direction of the expansion joint.

[0012] Further, the plurality of lower rib plates are arranged at intervals along the length direction of the expansion joint.

[0013] Further, one side of the water stop flange away from the vertical side plate extends obliquely upward to form an arc portion, and the inner arc surface of the arc portion faces the upper part of the vertical side plate.

[0025] The following further elaborates the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant invention and do not limit the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and in conjunction with the embodiments.

[0027] Referring to Figures 1 to 6 As shown, the present invention provides an integral embedded expansion joint structure for the roof, including: vertical side plates 1, bearing flanges 2, water-stop flanges 3, and rubber plates 4.

[0028] The number of the vertical side plates 1 is two. The two vertical side plates are arranged oppositely. An expansion gap is formed between the two vertical side plates 1. The height of the vertical side plates 1 is adapted to the thickness of the roof floor slab 5.

[0029] The bottom of the two vertical side plates 1 extends backward to form bearing flanges 2.

[0030] The middle parts of the two vertical side plates 1 extend backward to form water-stop flanges 3. A clamping gap is formed between the vertical side plates 1 and the water-stop flanges 3.

[0031] The rubber plate 4 is vertically arranged movably in two expansion joints. An upper flange 41 for sealing the upper joint of the expansion joint is formed by extending the top of the rubber plate 4. A lower flange 42 for sealing the lower joint of the expansion joint is formed by extending the bottom of the rubber plate 4. Pulling flanges 45 are respectively formed on the opposite sides of the rubber plate 4. The clamping joint is clamped between the pulling flanges 45. A plurality of upper rib plates 43 are formed on the upper part of the rubber plate 4. The upper rib plates 43 are connected between the upper flange 41, the upper part of the vertical side plate 1 and the upper part of the pulling flange 45. A plurality of lower rib plates 44 are formed on the lower part of the rubber plate 4. The lower rib plates 44 are connected between the lower flange 42, the lower part of the vertical side plate 1 and the lower part of the pulling flange 45.

[0032] The integral embedded expansion joint structure for the roof of the present invention is used to be integrally embedded in the expansion joint of the roof floor slab. When the expansion joint is relatively long, a plurality of integral embedded expansion joint structures for the roof are buried in the expansion joint of the roof floor slab, and the vertical side plates of adjacent integral embedded expansion joint structures for the roof are hermetically connected together.

[0033] In this embodiment, the opposite sides of the upper flange are hermetically connected between the upper parts of the vertical side plates; the opposite sides of the lower flange are hermetically connected between the lower parts of the vertical side plates; the pulling flange is hermetically connected to the inner wall of the clamping joint of the water stop flange; the upper rib plate and the lower rib plate are integrally formed and hermetically connected to the vertical side plate, so that the two vertical side plates of each integral embedded expansion joint structure for the roof are hermetically connected.

[0034] In this embodiment, the positions of the upper rib plates 43 and the lower rib plates 44 correspond to each other. The rubber plate, the upper flange, the lower flange, the pulling flange, the upper rib plate and the lower rib plate are integrally formed rubber structures.

[0035] The integral embedded expansion joint structure for the roof of the present invention is applicable to structures such as roofs and floors that need to be provided with expansion joints. By using the combined structure of the vertical side plates and the rubber plate, the waterproof and anti-seepage performance of the expansion joint is improved. At the same time, the integration construction of the expansion joint and the roof floor slab (or floor) is realized, eliminating processes such as cutting joints, cleaning ash and sealing with elastic materials, improving the construction efficiency. At the same time, the device can be freely customized in length, avoiding on-site processing of materials, with strong applicability and greatly improving the work efficiency.

[0036] The vertical side plates of the integral embedded expansion joint structure for the roof of the present invention play the role of fixing to the base layer of the roof floor slab and vertical sealing. The water stop flange is located in the middle of the vertical side plate, playing the role of blocking water and preventing water from entering the roof decorative layer along the side wall of the vertical side plate.

[0037] The elastic rubber sheet is fixed in the middle of the two vertical side panels. It has excellent weather resistance, high and low temperature resistance and adhesion, and plays a role in sealing and connecting. The upper flange is located on the top of the elastic rubber sheet. The upper flange is 2 to 4 cm wide and mainly plays a sealing role to prevent water vapor from entering the expansion joint. The upper surface of the upper flange is covered with a layer of protective tape, which will be uncovered after the roof construction is completed to protect the surface of the rubber strip from contamination.

[0038] The tie flange is located in the middle of the elastic rubber plate. The tie flanges on both sides of the rubber plate are tightly combined with the clamping gaps in the water stop flanges, increasing the length of the water permeable path and playing a water stop role.

[0039] The lower flange is located at the bottom and both sides of the elastic rubber plate to prevent water vapor from penetrating into the telescopic cavity and affecting the use effect.

[0040] The roof pre-embedded integrated expansion joint structure of the present invention is installed before the construction of the roof decoration structure, and is installed at the expansion joint position according to the requirements of the drawings. The bottom of the pressure flange and the base layer of the roof floor are fixed by mortar or other cementitious materials, and the joints of the vertical side panels of the adjacent roof pre-embedded integrated expansion joint structure are fixed by full welding.

[0041] When constructing the roof decoration structure, it is necessary to fill the lower space of the water stop flange tightly before constructing the upper structure. When constructing the roof surface layer to the upper flange, try to avoid contaminating the rubber strip. After the roof structure construction is completed, remove the protective tape on the upper flange to ensure the cleanliness of the upper flange.

[0042] In this embodiment, two opposite sides of the rubber plate 4 are respectively provided with gaps from the two vertical side plates 1. The thickness of the rubber plate is smaller than the width of the expansion gap.

[0043] As a preferred embodiment, a plurality of upper ribs 43 are arranged at intervals along the length direction of the expansion gap, and a plurality of lower ribs 44 are arranged at intervals along the length direction of the expansion gap.

[0044] See also Figure 3 As shown, the side of the water stop flange 3 away from the vertical side plate 1 extends obliquely upward to form an arc portion 31. The inner arc surface of the arc portion 31 is arranged toward the upper part of the vertical side plate 1.

[0045] See also Figure 1 As shown, a plurality of accommodating grooves a are formed on the opposite sides of the two vertical side plates 1 and the upper surface of the pressure-bearing flange 2. The accommodating grooves a are arranged along the length direction of the expansion gap.

[0046] In this embodiment, a plurality of convex ridges b are formed on the opposite sides of the two vertical side plates 1 and the upper surface of the pressure-bearing flange 2. The convex ridges and the receiving grooves are arranged in the same direction. The plurality of convex ridges and the plurality of receiving grooves are arranged alternately.

[0047] The cross-sections of the accommodation grooves and the convex ribs of the embedded integrated expansion joint structure on the roof of the present invention are semi-circular. A plurality of accommodation grooves are uniformly arranged along the vertical direction on the opposite sides of the vertical side plates and the bearing flanges, increasing the friction between the roof floor slab and the embedded integrated expansion joint structure of the present invention, so that the two are better combined together.

[0048] The above description is only the preferred embodiment of the present application and the explanation of the technical principles applied. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the present application that have similar functions.
