Abstract
A preparation method of a floor plate comprises three steps of manufacturing a three-dimensional trussed type steel bar net rack, preparing concrete materials and manufacturing the floor plate. The three-dimensional trussed type zinc-coated steel wire net rack is connected with high performance concrete in a solidification mode, so that the floor plate has high bearing capacity and high durability, and is simple and easy to install, fast in construction speed, reductive in pollution on site, and saving in a great amount of steel, concrete and wood and expenses of labors, water and electricity. The floor plate can be standardized in a factory and manufactured in a scale mode, and is an innovation-type assembly type strong intensity floor plate.
Description
Technical field:
The present invention relates to a kind of preparation method of floorboard, particularly a kind of energy is by the preparation method of each room-sized manufacturing, a floorboard of installation.
Technical background:
At present, the existing floorboard of China is made, basically all adopt the construction method of on-the-spot cast-in-place concrete, this kind method operation is many, long in time limit, cost is high, the waste material, particularly waste a large amount of timber, the annual plank sheathing quantity for building in the whole nation is surprising, has a strong impact on ecological environment and the waste that causes ample resources.
Application number is the floorboard preparation method in " preparation method of 200710014751.9 outer board walls, lining, floorboard, roof boarding ", is floorboard is made on an empty stomach shape, and post-foaming polyurethane is as heat-insulation layer in empty stomach.This method for designing science relatively aspect insulation, but aspect bearing load because cavity is arranged, so detect by in kind, prove that this method can only be done than the small size floorboard to use, do not satisfy the purpose of a floorboard of whole room installation.
Summary of the invention:
Purpose of the present invention will provide a kind of high antidetonation, high-bearing capacity exactly, installation is simple and easy, speed of application is fast, reduce on-the-spot the pollution, and can save great deal of steel, concrete, timber and labour cost, water, electricity charge usefulness, and the preparation method of the plant-manufactured floorboard of energy.
The object of the present invention is achieved like this: a kind of preparation method of floorboard is characterized in that it may further comprise the steps:
(1) makes the three-dimensional truss bar frame: 1. make the net sheet, the cold-drawn galvanizing steel, the cold-drawn zinc-coated wire, by designing requirement cloth silk on numerical control bonding machine, rear with numerical control bonding machine that it is vertical, horizontal cold-drawn galvanizing steel, cold-drawn zinc-coated wire right-angled intersection point welds, form the net sheet, the net sheet reinforcing bar that forms is divided into two kinds in main muscle and auxiliary muscle, main muscle is the cold-drawn galvanizing steel, auxiliary muscle is the cold-drawn zinc-coated wire, it is vertical, be three auxiliary muscle between two horizontal main muscle, between main muscle and the auxiliary muscle, mesh between auxiliary muscle and the auxiliary muscle all≤60mm, the main muscle of net sheet and auxiliary muscle will be given prominence to net sheet surrounding, ledge is rack evagination anchor bar, and its length is not less than 30 times of main muscle diameters; 2. form bar frame, between two layers of net sheet, on the net sheet master muscle of upper and lower two layers of correspondence, with X-type galvanizing steel bridging and galvanizing steel column, the main muscle of two layers of net sheet is implemented support draw welding, just formed three-dimensional truss galvanizing steel rack, the angle of X-type bridging formula intersection joint bar is 35 °-60 °;
(2) preparation concrete material: the composite material of concrete is: label 42.5 and above cement, hard rock stone, hard rock sand and hard rock fine sand, SILICA FUME, first level flour coal ash, water that particle diameter is 15mm to the maximum and efficiently reduce agent, above raw material are mixed in proportion, match ratio material design concrete strength is C35-C40, carry out electronic measurement, classification is given and being mixed, add at last water and stir, and accomplish with mixing with usefulness.
(3) floorboard is made: 1. the moulding bar frame is fixed on the mould, on rack four limits inwards on the rack at 500-800mm place, perpendicular tie up the plastic tube that four rings of tying up when being used for lifting are used, at steel shock platforms upper berth layer of glass fiber grid cloth, mould and rack are placed on above the glass fiber reticular cloth, the concrete material that stirs is evenly distributed in the mould, the starting shock platform is implemented vibrations, the smooth making of just finishing floorboard of supreme plane motion again.
Form bar frame in the making three-dimensional truss bar frame of the present invention, between two layers of net sheet, minute long to, short the net sheet master muscle of upper and lower two layers of correspondence, make column with X-type galvanizing steel bridging with galvanizing steel, the main muscle of two layers of net sheet is implemented support draw welding, just formed three-dimensional truss galvanizing steel rack, galvanizing steel column center is not more than 15mm from net sheet right-angled intersection dot center distance.
Form bar frame in the making three-dimensional truss bar frame of the present invention, between two layers of net sheet, only need on short the net sheet master muscle of upper and lower two layers of correspondence, make column with X-type galvanizing steel bridging with galvanizing steel, the main muscle of two layers of net sheet is implemented support draw welding, just formed another kind of three-dimensional truss galvanizing steel rack, galvanizing steel column center is not more than 12mm from net sheet right-angled intersection dot center distance.
The present invention compared with prior art has the following advantages:
Owing to adopted above technical scheme, thereby had the following advantages:
1, intersect joint bar by galvanized steel reinforcing mesh sheet and galvanizing steel column and galvanizing steel, through the bar frame that the NC welding machine welding forms, its stretching-resisting bending-resisting intensity is high, and stressed evenly, can satisfy and surpass existing cast-in-place floorboard design specification index.
2, adopt this galvanizing steel rack to compare with the way of existing cast-in-place concrete colligation bar reinforcing bar and can save a large amount of amount of reinforcement; and because rack is zinc-plated; the concrete of parcel rack is high-strength, high density, water-tight concrete; can form admirably protective effect to bar frame, the two combines and can realize century-old Architectural Design Requirements.
3, floorboard can be realized batch production, standardization, scale manufacturing and industrialization assembling application, and has saved the facility expense that a large amount of artificial, material reach relevant site operation, particularly saves a large amount of plank sheathings and facilities and equipment expense.
4, speed of application is fast, can significantly shorten the duration of a project.
What 5, adopt is the three-dimensional truss bar frame, the combination of grid structure and high performance concrete, under the prerequisite of saving great deal of steel, its bearing capacity is more than 2 times of existing cast-in-place concrete floor after tested, and its one anti-seismic performance and Durability Status are very good.
