[0002] With the continuous development of engineering construction, there are more and more ultra-long and ultra-wide structures. Controlling the cracks caused by temperature stress and dry shrinkage deformation is the key and difficult point in the construction of ultra-long structures. To solve the above problems, deformation joints are generally set. For bidirectional ultra-long structures, cross-shaped deformation joints need to be set, and copper sheets or rubber cross-shaped waterstops are set in the joints. Among them, the copper sheet waterstop has the advantages of high strength, strong water pressure resistance and anti-seepage ability, etc. However, due to the orientation problem of the "nose", the horizontal deformation coordination ability of the cross-shaped copper waterstop is uneven in four directions, and the copper is often torn; the rubber waterstop has good elasticity, is not easily damaged during construction, and can withstand a large joint displacement, but its strength is lower than that of the copper waterstop.

[0003] Therefore, how to improve the overall structural stability of the cross-shaped deformation joint and avoid the leakage risk caused by the unreasonable structure of the waterstop at the junction is a technical problem that needs to be solved urgently. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] Embodiment 1

[0030] As Figure 1 shown, this embodiment provides a composite cruciform expansion joint structure, including a copper waterstop 1, a rubber waterstop 2, and a connecting copper sheet 3;

[0031] The copper waterstop 1 is of a cruciform structure. The copper waterstop 1 is a conventional setting, similar to the existing cruciform copper waterstop structure, and the nose at the end is sealed with two-component polysulfide rubber or two-component polyurethane rubber. A rectangular window is provided at the center of the copper waterstop 1. As Figure 2 shown, the horizontal side of the rectangular window is parallel to the horizontal wing plate of the copper waterstop 1, and the width of the horizontal side of the rectangular window is the same as that of the vertical wing plate of the copper waterstop 1. At the same time, the vertical side of the rectangular window is parallel to the vertical wing plate, and the width of the vertical side of the rectangular window is the same as that of the horizontal wing plate.

[0032] The rubber waterstop 2 is of a rectangular structure, and the size of the rubber waterstop 2 is 300x300 mm.

[0033] The connecting copper sheet 3 is of a square frame structure, with a thickness of 1.2 mm and a width of 30 mm. The connecting copper sheet 3 is located within the rectangular window. The rubber waterstop 2 is located within the connecting copper sheet 3. The inner edge of the connecting copper sheet 3 extends into the interior of the rubber waterstop 2, and the outer edge of the connecting copper sheet 3 is welded and fixed to the copper waterstop 1.

[0034] Specifically, the rubber waterstop 2 includes a deformation part and a conical part 21 arranged circumferentially along the deformation part. The cross-section of the conical part 21 is a conical structure, and the conical tip faces outward. As Figure 3 shown, the inner edge of the connecting copper sheet 3 extends 30 mm into the conical tip of the conical part 21 (i.e., the entire connecting copper sheet 3 extends into the conical part 21, and only the outer edge is exposed). The inner edge of the connecting copper sheet 3 is adhesively fixed to the conical part 21 and meets the rubber and steel belt adhesion test, with an adhesion strength ≥ 6 Mpa. The adhesion between the rubber and the steel belt is good, safe and reliable.

[0035] Among them, the deformation part includes a rectangular base band 22, and a cross-shaped hollow cylinder 23 is formed at the center of the rectangular base band 22. The thickness of the rectangular base band 22 is 10 mm. The outer radius of the cross-shaped hollow cylinder 23 is 15 mm, the radius of the hollow circle is 7 mm, and the thickness of the ring is 8 mm. The conical part 21, the rectangular base band 22, and the cross-shaped hollow cylinder 23 are of an integral structure.

[0036] Based on the above structure, the composite cross-shaped deformation joint structure provided in this embodiment combines the advantages of both the copper waterstop and the rubber waterstop, solves the problems of easy leakage and uneven deformation at the cross-shaped deformation joint, and provides a good solution for the two-way super-long structure. Among them, the rubber waterstop 2 adopts a cross-shaped hollow cylinder structure in the deformation joint area, which can increase the deformation ability and durability.

[0037] Embodiment 2

[0038] As Figures 4 - 5 shown, the difference from Embodiment 1 is that the rubber waterstop 2 includes a deformation part and a conical part 21 arranged circumferentially along the deformation part.

[0039] Furthermore, the deformation part includes a rectangular base band 22, and a cross-shaped waveform structure 24 is formed at the center of the rectangular base band 22, and a hollow sphere structure is formed at the center of the cross-shaped waveform structure 24.

[0040] In this embodiment, the upper convex arc surface and the lower concave arc surface of the waveform structure appear alternately, and the outer radius of the arc surface is 15 mm, the inner radius is 7 mm, and the plate thickness is 8 mm. The conical part 21, the rectangular base band 22, and the cross-shaped waveform structure 24 are of an integral structure.

[0041] Based on the above structure, the composite cross-shaped deformation joint structure provided in this embodiment combines the advantages of both the copper waterstop and the rubber waterstop, solves the problems of easy leakage and uneven deformation at the cross-shaped deformation joint, and provides a good solution for the two-way super-long structure. Among them, the rubber waterstop 2 adopts a two-way waveform structure in the deformation joint area, which can increase the ability of multi-directional deformation.

[0042] Example 3

[0043] As Figures 6 - 7 shown, the difference from Example 1 is that the rubber waterstop 2 includes a deformed part and a conical part 21 arranged circumferentially along the deformed part.

[0044] Furthermore, the deformed part is a hollow cube structure, and its internal hollow is a spherical structure.

[0045] In this embodiment, the rectangular window opened at the center of the copper waterstop 1 is smaller than that in the previous two embodiments. Correspondingly, the size of the rubber waterstop 2 is also smaller.

[0046] Equivalently, the rubber waterstop 2 only includes a hollow cube structure and a conical part 21 arranged circumferentially along the hollow cube structure. The size of the hollow cube structure is 30x30mm, and the radius R of the internal hollow sphere is 10mm.

[0047] Based on the above structure, the composite cross-shaped deformation joint structure provided in this embodiment combines the advantages of the copper waterstop and the rubber waterstop, solves the problems of easy leakage and uneven deformation at the cross-shaped deformation joint, and provides a good solution for the bidirectional super-long structure. Among them, the rubber waterstop 2 adopts a three-dimensional structure with a hollow circle in the middle in the form of a cube in the cross area of the deformation joint, which can increase the deformation ability and durability.

[0048] To sum up, the construction process (taking the pouring of the bottom slab of the clean water tank as an example) of the composite cross-shaped deformation joint structure provided in Examples 1-3 can include the following steps:

[0049] 1. The composite cross-shaped deformation joint structure is manufactured by the manufacturer. The reserved length of the copper waterstop around is ≥300mm, and it is welded to the external copper waterstop. The welding should use a brass electrode.

[0050] 2. Measuring and setting out: According to the design drawings, place the composite cross-shaped deformation joint structure and the copper waterstop in the remaining areas.

[0051] 3. During construction, the opening area of the nose part of the copper waterstop should be closed to prevent sundries from filling the opening.

[0052] 4. There are a total of four grid areas. It is recommended to pour the concrete diagonally.

[0053] 5. During the concrete construction around the waterstop, the displacement, damage or distortion of the waterstop should be prevented. When the waterstop is laid horizontally, it should be ensured that the concrete under the waterstop is vibrated compactly.

[0054] The mechanisms, components and parts not described in detail in the present utility model are existing structures that already exist in the prior art and can be directly purchased from the market.

[0055] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0056] The above is only a preferred implementation of the present utility model, and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
