Description

Technical Field

[0001] This utility model belongs to the field of building seismic isolation technology, specifically relating to a simple seismic isolation joint cover plate device. Background Technology

[0002] Seismic isolation technology is one of the most effective technical measures to enhance the seismic performance of building structures and mitigate earthquake damage. Seismic isolation technology ensures that seismically isolated buildings function properly during earthquakes by reserving space through seismic isolation joints. Seismic isolation joints are vertical joints set in building components, and a cover plate device is required at the top of the joint to seal it and bear the load from above. However, disaster results show that in seismically isolated buildings, especially in medium- and high-intensity seismic zones, the cover plate device on the seismic isolation joints or trenches presents several factors that affect the seismic performance of the seismic isolation structure:

[0003] 1) Existing rubber-insulated flat-type seismic isolation joint cover plates and other devices are suitable for joints with small widths, which cannot meet the minimum joint width requirement of 300mm for seismic isolation joints;

[0004] 2) Existing metal cover plate devices are complex in shape, expensive, and inconvenient to install. Moreover, the expansion joint cover plate device has a large in-plane stiffness, which makes its deformation capacity easily affected, thus hindering the deformation of the main structure on both sides, and the maintenance cost is also very high. Utility Model Content

[0005] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a simple seismic isolation joint cover plate device, suitable for vertical seismic isolation joints with a width of 300-600mm.

[0006] To achieve the above objectives and technical effects, the technical solution adopted by this utility model is as follows:

[0007] A simple seismic isolation joint cover plate device includes a telescopic corrugated steel plate, a rubber cover plate, and expansion anchor bolts. The rubber cover plate is laid on the telescopic corrugated steel plate, and the two sides of the telescopic corrugated steel plate are connected to the civil engineering components on both sides of the seismic isolation joint by expansion anchor bolts.

[0008] Furthermore, the cross-section of the telescopic corrugated steel plate is corrugated.

[0009] Furthermore, the telescopic corrugated steel plate is made of Q235 steel plate with a plate thickness of not less than 2mm and a rib height of not less than 40mm.

[0010] Furthermore, several long bolt holes are provided on both sides of the telescopic corrugated steel plate.

[0011] Furthermore, the length of the long bolt hole is 600mm.

[0012] Furthermore, a rubber cover plate is adhered to the upper surface of the telescopic corrugated steel plate.

[0013] Furthermore, a rubber cover plate is bonded to the upper surface of the telescopic corrugated steel plate by an adhesive layer, the shape and size of which are adapted to the telescopic corrugated steel plate.

[0014] Furthermore, the adhesive layer includes an upper double-sided adhesive layer, a buffer layer, and a lower double-sided adhesive layer arranged sequentially from top to bottom. The upper double-sided adhesive layer is bonded to the rubber cover plate, and the lower double-sided adhesive layer is bonded to the expansion corrugated steel plate.

[0015] Furthermore, the total thickness of the adhesive layer is 8-12mm, and the thicknesses of the upper double-sided adhesive layer and the lower double-sided adhesive layer are 3-5mm respectively.

[0016] Furthermore, the civil engineering components on both sides are manufactured and constructed according to the structural construction drawings. After the concrete strength is cured to 100%, a simple seismic isolation joint cover plate device is installed simultaneously in conjunction with the building surface layer process.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model discloses a simple seismic isolation joint cover plate device. The cross-section of the expansion corrugated steel plate is corrugated, which provides vertical support capacity. Its stiffness in the X-plane is much smaller than that of a flat steel plate, which can meet the relative X-direction displacement of the civil engineering components on both sides of the seismic isolation joint. Long bolt holes are provided at the connection between the expansion corrugated steel plate and the expansion anchor bolts on both sides, which can coordinate the relative Y-direction displacement of the civil engineering components on both sides. The resulting seismic isolation joint cover plate device has the ability to deform autonomously in both the horizontal X and Y directions. The seismic isolation joint cover plate device has the characteristics of easy material sourcing, low cost, easy replacement, convenient installation and maintenance, and no need for continuous maintenance. The thickness of the expansion corrugated steel plate can be flexibly adjusted according to different seismic isolation joint widths. It is highly practical and suitable for industrial promotion and use. Attached Figure Description

[0021] The present invention will now be described in detail so that its advantages and features can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0023] like Figure 1-2 As shown, a simple seismic isolation joint cover plate device includes a telescopic corrugated steel plate 1, a rubber cover plate 2, and expansion bolts 3. The rubber cover plate 2 is laid on the telescopic corrugated steel plate 1 to bear the upper load. The two sides of the telescopic corrugated steel plate 1 are connected to the civil engineering components 4 on both sides of the seismic isolation joint through expansion bolts 3 to seal the seismic isolation joint. The cross-section of the telescopic corrugated steel plate 1 is corrugated, and its stiffness in the X-direction plane is much smaller than that of a flat steel plate, which can meet the X-direction relative displacement of the civil engineering components 4 on both sides of the seismic isolation joint.

[0024] In some embodiments, a rubber cover plate 2 is adhered to the upper surface of the telescopic corrugated steel plate 1.

[0025] In some embodiments, thickened steel plates 5 are provided on both sides of the expansion corrugated steel plate 1, and several long bolt holes 1-1 are provided on both sides of the expansion corrugated steel plate 1. Expansion anchor bolts 3 are inserted into the long bolt holes 1-1, so that both sides of the expansion corrugated steel plate 1 are connected to the civil engineering components 4 on both sides of the seismic isolation joint and below the building surface layer 6 through the expansion anchor bolts 3. The relative displacement of the civil engineering components in the Y direction can be adjusted through the long bolt holes 1-1.

[0026] In some embodiments, the expansion corrugated steel plate 1 is fixed to the upper surface of the civil engineering components 4 on both sides by Φ8 plastic expansion anchor bolts, with the Φ8 plastic expansion anchor bolts located near the midpoint of the long bolt hole.

[0027] In some implementations, the expansion corrugated steel sheet 1 is made of Q235 steel plate with a thickness of not less than 2mm, and the rib height is determined according to the building surface layer, generally not less than 40mm. This steel sheet can be purchased as ordinary profiled steel sheet, or it can be purchased as steel sheet and bent in the factory.

[0028] In some embodiments, the thickness of the rubber cover plate 2 is not less than 10 mm.

[0029] In some embodiments, a rubber cover plate 2 is bonded to the upper surface of the telescopic corrugated steel plate 1 by an adhesive layer, the shape and size of which are adapted to the telescopic corrugated steel plate 1.

The upper double-sided adhesive layer is bonded to the rubber cover plate 2, and the lower double-sided adhesive layer is bonded to the expansion corrugated steel plate 1.

[0031] In some embodiments, the total thickness of the adhesive layer is 8-12 mm, and the thicknesses of the upper double-sided adhesive layer and the lower double-sided adhesive layer are 3-5 mm, respectively.

[0032] Civil engineering component 4 is usually made of concrete, but steel structural components can also be used. To ensure the bolting requirements of the cover joint device, connectors can be pre-embedded, post-installed, or welded.

[0033] When the actual earthquake displacement is less than the design value, the expansion corrugated steel plate 1 will not be damaged and does not need to be replaced; only the rubber cover plate 2 needs to be re-attached.

[0034] Compared with existing rubber-insulated flat type seismic isolation joint cover plates, the seismic isolation joint cover plate device of this utility model has significantly improved bending stiffness and vertical bearing capacity, and can meet the requirement of seismic isolation joint width (and clear span of seismic isolation cover plate) of 300-600mm.
