Description
Technical Field
The utility model relates to a cushion, more specifically the reinforcing bar concrete column core cushion that is used for jacking to add layer that says so.
Background
With the development of building industry, the concept of building storey-adding design in modern society has become a topic that is more generally concerned by industrial people. The house floor-adding has the advantages of no land occupation, less investment, quick effect, capability of quickly solving the problem of lacking houses and the like, and is particularly suitable for the national conditions of China, so that a great amount of old house floor-adding transformation is carried out in China in recent years, and good economic benefit and success are achieved.
At present, a building storey-adding reconstruction technology is gradually developed, and cushion blocks are placed below frame columns when the frame columns are jacked in the building storey-adding reconstruction technology. However, some existing cushion blocks cannot meet the requirement of jacking storey-adding height because of no reliable connection, no limitation of pressure-resistant bearing capacity and superposition height; some have then to connect the structure complicacy, and the process is loaded down with trivial details, has guaranteed the stability of jacking in-process frame post and the demand of jacking height, but actual operation is very difficult, is difficult to be applied to in the actual engineering.
Disclosure of Invention
The utility model aims to provide a reinforcing bar concrete column core cushion that is used for building jacking to increase floor to the restriction that does not have reliable connection and coincide height, the resistance to compression bearing capacity not enough, perhaps construct defects such as complicated operation difficulty that exist of current cushion.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides a reinforcing bar concrete column core cushion for jacking increases layer, includes upper portion piece and lower part piece, upper portion piece and lower part piece be cuboid massive structure, the upper portion piece sets up at lower part piece top surface middle part, upper portion piece side is provided with reinforcing bar jack I, lower part piece top surface both sides be provided with reinforcing bar jack II respectively, be provided with cylindrical steel cake I between the top panel of upper portion piece and the bottom surface board, be provided with cylindrical steel cake II between the top panel of lower part piece and the bottom surface board.
The cylindrical steel cakes I are four and are connected through steel pipes I.
The number of the cylindrical steel cakes II is four, and the four cylindrical steel cakes II are connected through steel pipes II.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the steel cake is arranged in the steel reinforced concrete column core cushion block, and compared with a common reinforced concrete cushion block, the compression resistance bearing capacity of a single cushion block is greatly improved.
2. The structure is simple, the top cushion block and the bottom cushion block are reliably connected, and the problem that relative sliding is easy to occur between a plurality of cushion blocks in the prior art is solved.
3. The number of layers of the top cushion block and the bottom cushion block can be designed according to actual conditions, the limitation of overlapping height in the prior art is solved, and the requirement of jacking storey-adding height is met.
4. The stacking construction operation between the top cushion block and the bottom cushion block and between the plurality of top cushion blocks is simple and convenient, and simultaneously, the stacking construction operation can be directly used as a column core of the heightening part of the frame column.
