Summary of the invention
The purpose of this utility model is a kind of steel plate-brickwork combination stressed member that provides for the deficiencies in the prior art, use this member can overcome conventional steel reinforced concrete method exist wet trade many, need temporary supporting and template, the member section attractive in appearance and use of building and the shortcoming such as long in time limit of affecting bigger than normal, its short construction period, overall appearance.
The purpose of this utility model is achieved in that
A kind of steel plate-brickwork combination stressed member, be characterized in that this primary structure member comprises masonry, steel plate, split bolt and epoxy resin, steel plate coats masonry, split bolt runs through masonry and steel plate and is fixedly connected with steel plate, in the slit of epoxy resin filling between masonry and steel plate, wherein: described masonry is body of wall or the cylinder that brick and concrete are built into; Described steel plate is Q235 or Q345 steel, and steel plate thickness is 8～12mm.
The relative masonry of steel plate in the utility model possesses very high tension, compressive strength, but steel plate is less because of the sectional dimension of self, and its stability is very poor, constructs to be easy to occur cripling or whole unstability when unreasonable.Masonry has certain compressive strength usually, and tensile strength is very low, but its sectional dimension is relatively large.Steel plate and masonry are by split bolt and the whole co-operation of the rear formation of structure glue binding material constraint, and steel plate has certain effect of contraction to masonry, can improve intensity and the deformability of masonry; Reperfusion structure glue can strengthen the masonry globality and steel plate is produced lateral restriction; Masonry plays the effect that delays even stop the cripling unstability to encased steel plate.Steel plate and masonry are maximized favourable factors and minimized unfavourable ones, and jointly improve the usefulness of material.Therefore, the force-mechanism of this combined member is very rational.
When the utility model carried out large-space rebuilding in the masonry load-carrying members, except based process was identical with traditional method, its superstructure obviously played the purpose of saving the duration owing to there not being the wet trade of concrete construction; Masonry wall and the encased steel plate collaborative work of steel plate-brickwork combination stressed member position are set, give full play to the contribution of residual body of wall; In the work progress, because steel plate forms whole participation work with body of wall first, and then carries out the body of wall overall pulling down, so do not need support template and safety supports; Steel plate is owing to self very thin thickness, and the sectional dimension of steel plate-brickwork combination stressed member is very little to appearance effects; Because steel plate is welded and installed outsourcing body of wall, so can do orthogonal, T shape or L shaped to steel plate-brickwork combination stressed member section as required, global shape is attractive in appearance.
