Problems solved by technology

[0002] Seismic isolation has become one of the most widely used shock-absorbing methods because of its simple concept, obvious effect and stable performance. So far, about 5,000 seismic-isolated buildings around the world have basically used laminated steel plate rubber bearings. However, because of its high price and complicated construction technology, this kind of support is not suitable for the shock isolation and shock absorption of house buildings in vast villages and towns where the economy and technology are relatively weak.
On the other hand, due to the low number of buildings in villages and towns, the weight is small, and the total investment is relatively small. When using laminated steel plate rubber seismic isolation bearings, the design surface pressure of the bearings is far less than its compressive stress limit, resulting in greater waste.

Embodiment 1

[0034] Clean the mold table and apply the release agent on the required work table. Lay a layer of release cloth on the area where the release agent is applied, stack the prepared 5 layers of 04 glass fiber grid cloth on the release cloth in order, and place a guide on the fiber grid cloth Net, except for the side reserved for glue injection, the diversion net in other areas needs to be 30-40mm away from the edge of the glass fiber grid cloth, and then wrap the glass fiber grid cloth and the diversion net with a release cloth.

[0035] Arrange the exhaust pipe and rubber injection pipe at both ends of the release cloth. The air extraction pipe is wrapped and lifted with the release cloth, the rubber injection pipe is wrapped with the release cloth, and the sealant is fixed. The air suction pipe extracts the air in the release cloth to reduce the pressure of the space wrapped by the release cloth to 3MPa~6MPa, and then pour the defoamed epoxy resin into the glass fiber grid clo...

Embodiment 2

[0049] Clean the mold table and apply the release agent on the required work table. Lay a layer of release cloth on the area where the release agent is applied, stack the prepared 5 layers of 04 glass fiber grid cloth on the release cloth in order, and place a guide on the fiber grid cloth Net, except for the side reserved for glue injection, the diversion net in other areas needs to be 30-40mm away from the edge of the glass fiber grid cloth, and then wrap the glass fiber grid cloth and the diversion net with a release cloth.

[0050] Arrange the exhaust pipe and rubber injection pipe at both ends of the release cloth. The air extraction pipe is wrapped and lifted with the release cloth, the rubber injection pipe is wrapped with the release cloth, and the sealant is fixed. The air suction pipe extracts the air in the release cloth to reduce the pressure of the space wrapped by the release cloth to 3MPa~6MPa, and then pour the unsaturated polyester after the defoaming treatmen...

Embodiment 3

[0064] see figure 1 , the high-damping simple shock-isolation bearing in this embodiment includes a bearing main body; the bearing main body is formed by alternately superimposing and vulcanizing rubber layers 1 and engineering plastic plates 2, and the upper sealing plate is the topmost engineering plastic plate 2, and the lower The sealing plate is the lowest engineering plastic plate 2, and the thickness of the upper sealing plate and the lower sealing plate is greater than that of the engineering plastic plates 2 of other layers. The damping ratio of the rubber layer 1 is 5%-30%. The high-damping simple shock-isolation support also includes a rubber protective layer 3 wrapping the main body of the support.

[0065] The engineering plastic plate 2 is basically the same as the engineering plastic plate in Embodiment 1, the difference is that: the engineering plastic plate adopted by the upper sealing plate and the lower sealing plate contains 31 layers of glass fiber grid c...

Abstract

The invention relates to the technical field of a composite material, and particularly relates to a glass fiber reinforced engineering plastic plate. The engineering plastic plate is mainly prepared from two-way longitude and latitude glass fibers, and engineering plastic injected between the two-way longitude and latitude glass fibers. The invention also relates to the technical field of shock insulation, and particularly relates to a high-damping isolating bearing. By adopting the simple high-damping isolating bearing, common laminated rubber medium steel plate is replaced by using the engineering plastic plate, the simple high-damping isolating bearing is low in price, simple in construction technology, and applicable to broad rural areas with relatively weak economy and technique, and the compressive stress limit is smaller than that of a laminated steel pate rubber bearing.

Description

technical field [0001] The present invention relates to the technical field of composite materials, more specifically to a glass fiber reinforced engineering plastic board and a manufacturing process of the glass fiber reinforced engineering plastic board; A high-damping simple shock-isolation bearing that replaces the steel plate in ordinary laminated rubber. Background technique [0002] Seismic isolation has become one of the most widely used shock-absorbing methods due to its simple concept, obvious effect and stable performance. So far, about 5,000 seismic-isolated buildings around the world have basically used laminated steel plate rubber bearings. But this kind of support is not suitable for the shock isolation and shock absorption of building buildings in vast villages and towns where the economy and technology are relatively weak because of its expensive price and complicated construction technology. On the other hand, due to the low number of buildings in villages...
