Above-mentioned and in prior art, there are two in the main direction of development of concrete composite floor: on one hand, with the increasing shortage of resources in China, the problem of searching for novel environment-friendly and ecological materials for engineering construction needs to be solved urgently; on the other hand, the bearing capacity, the overall performance and the seismic performance of the concrete composite floor slab are improved, so that the concrete composite floor slab can be close to or even exceed a cast-in-place structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a steel fibre recycled concrete coincide floor to solve the above-mentioned weak point among the prior art.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a steel fibre recycled concrete coincide floor, includes prefabricated bottom plate, integrated into one piece has the truss that is equidistant structure distribution on the top outer wall of prefabricated bottom plate, and the top pouring shaping of prefabricated bottom plate has concrete layer, the inside of prefabricated bottom plate and concrete layer all mixes steel fibre and recycled aggregate, and the inside homogeneous body shaping of prefabricated bottom plate and concrete layer has reinforcing bar net piece.

Preferably, the reinforcing mesh is distributed in a warp-weft line type structure.

Preferably, the longitudinal ribs and the transverse ribs of the truss are fixed in a # -shaped structure.

In the technical scheme, the utility model provides a pair of steel fibre recycled concrete coincide floor, make steel fibre recycled concrete according to certain ratio through utilizing recycled aggregate and steel fibre, the steel fibre recycled concrete that utilizes is a green material, recycled aggregate is through building refuse treatment come, not only practice thrift raw and other materials, green, the source is extensive, and can help handling building refuse, reach waste utilization, beautify the purpose of environment, and simultaneously, recycled concrete's stretch resistance has been improved, thereby the security performance of coincide floor has been improved.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model provides a pair of steel fiber recycled concrete coincide floor, including prefabricated bottom plate 2, integrated into one piece has the truss 3 that is equidistant structure distribution on the top outer wall of prefabricated bottom plate 2, and the top casting shaping of prefabricated bottom plate 2 has concrete layer 4, prefabricated bottom plate 2 and concrete layer 4's inside all mixes steel fiber 1 and regeneration aggregate 5, and the equal integrated into one piece in inside of prefabricated bottom plate 2 and concrete layer 4 has reinforcing bar net piece 6, reinforcing bar net piece 6 is longitude and latitude line formula structure distribution, truss 3's vertical muscle and horizontal muscle are well style of calligraphy structure fixed, regeneration aggregate is handled through building rubbish and comes, not only practice thrift raw and other materials, green, the source is extensive, and can help handling building rubbish, reach waste utilization, beautify the purpose of environment, and simultaneously, add the specific amount in the recycled concrete and cut off the fiber length that the thin method was made rather than the fibre of diameter at 50 ~ 75's fibre, the tensile property of recycled concrete has been improved, thereby the security performance of coincide floor has been improved.

In the steel fiber recycled concrete prefabricated base plate (2), the concrete per cubic meter contains the following components: 85kg of steel fiber, 1250kg of recycled brick aggregate, 500kg of cement, 250kg of water and 500kg of sand, wherein the steel fiber (1) is prepared by a method of cutting thin steel wires, and the ratio of the length of the fiber to the diameter of the fiber is 50-75.

The working principle is as follows: firstly, mixing and stirring the steel fiber (1) and the recycled aggregate (5) to uniformly mix the steel fiber and the recycled aggregate; then mixing the cement and the sand with the mixture of the steel fiber (1) and the recycled aggregate (5), firstly, dry-stirring and mixing, then, sequentially adding water and stirring, stirring for 3-4 minutes, and finally, preparing the steel fiber recycled concrete; then, a wood template of the prefabricated bottom plate is manufactured, longitudinal reinforcements and transverse reinforcements of the truss structure are bound according to a # -shaped structure, then, steel fiber recycled concrete is poured, after the upper layer of the bottom plate is leveled, rough surfaces are manufactured along longitudinal roughening, finally, standard maintenance is carried out for 14d, the template is removed, the steel fiber recycled concrete prefabricated bottom plate (2) is formed, when the strength of the prefabricated bottom plate reaches more than 80% of a design value, the template is erected firstly, the surface of the bottom plate is cleaned and moistened, then, a cast-in-place concrete layer reinforcement mesh (6) is laid, steel fiber concrete is poured, and after leveling, standard maintenance is carried out for 28 days.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention.
