Description
Technical field:
The invention belongs to building material technical field, be specifically related to ordinary steel silk screen concrete thin plates and manufacture method in the middle part of a kind of frame clad steel silk screen.
Background technology:
In engineering construction in particularly commercial building, industrial building; thin wallboard is often used to carry out interval, room, fire barriers; but owing to thin this body of wallboard face size is much larger than its thickness; wallboard rigidity is little; intensity is low; installing, in transport and application process, often occur that sheet edges easily knocks the problem that damage, plate face are easy to crack, thus have a strong impact on the use of thin wallboard.The thin wallboard main species that presently, there are has glass mat, silica-magnesia panel, ceramsite board, plasterboard, steel-wire-net reinforced concrete plate.Fibre board ceramsite board intensity is high, but this type of sheet material production cost is high: the heat preservation and soundproof performance that silica-magnesia panel has had, but exists in using and return the problem that halogen deformation etc. has a strong impact on construction quality；Panel strength is low, and hardness is little.Therefore, above material plate is little in real project scope, is not suitable for popularity and uses.
Steel-wire-net reinforced concrete thin plate intensity is high, and toughness is big, and as reinforced concrete member, the intensity of reinforcing bar and concrete bi-material obtains more sufficiently utilizing, and has good bearing capacity and deformability, becomes the optimum selection of thin wallboard material.Armoured concrete slab is currently used most commonly used a kind of version, for the response characteristic under the stress performance of this class formation and load action and reasonably method for designing and construction measure, numerous structural research personnel and engineers have been also carried out substantial amounts of research.During steel-wire-net reinforced concrete thin plate stress, during elastic stage, steel wire can resist the contraction of mortar；In the microcrack stage, the scholar of mortar becomes microcrack width rises control action, and during scholar becomes, microcrack quantity keeps constant, can well make up the breaking resistance that thin wallboard generally exists low, crack developing problem earlier.But, for steel-wire-net reinforced concrete thin plate, still there is thin plate circumferential side frame incipient crack and carry out relatively early, during stress, stress is concentrated, and easily produces the situation of cracking.
For improving the intensity of concrete component goods, and equalizing its economic benefit, this patent proposes ordinary steel silk screen concrete thin plates and manufacture method in the middle part of a kind of frame clad steel silk screen.While in concrete component, laying meets the steel wire of Structural Design Requirement, the method that concrete thin plates frame is combined smaller szie lattice steel silk screen, not only can ensure that tensile strength and the frame toughness of concrete thin plates frame, improve the durability of concrete thin plates, reduce crack, concrete thin plates component cost can also be reduced, obtain good economic benefit.It is suitable for extensively applying in Practical Project.
Summary of the invention
It is low generally to there is thin plate frame intensity in current concrete thin plates, easily knock damage, the defect that plate integrated carrying ability is low and cost is high, and, concrete thin plates incipient crack is often carried out early at frame, thus affect the use of concrete thin plates, in order to solve problem above, the present invention provides a kind of and has ordinary steel silk screen concrete thin plates and manufacture method in the middle part of simple to operate, cheap frame clad steel silk screen.
