Description

The concrete aggregate particle diameter is selected separator

One, technical field:

The utility model relates to a kind of separator, particularly relates to a kind of concrete aggregate particle diameter and selects separator.

Two, background technology:

Along with the aggravation of china natural resources imbalance between supply and demand and environment stress, problems such as Dwellings Buildings'Energy Economizing environmental protection more and more are subjected to the attention of national the departments concerned, and promotion and application novel wall structure then becomes the most important thing of body of wall innovation and building energy conservation.Built-in heat insulation concrete structural system is a kind of the steel wire net rack insulation sandwich board to be cast in the exterior wall concrete structure; the inboard concrete of body of wall designs by force structure; steel wire net rack insulation sandwich board outside concrete is considered the body of wall load-bearing heat insulation system (as shown in Figure 1) that inside and outside both sides concrete is built simultaneously as topping.The insulation network frame plate adopts two-layer reinforced mesh 10 and oblique cutting reinforcing bar 11 to constitute skeleton, intermediate arrangement heat preservation and soundproof polyphenyl plate 13, and the two-sided concreting 12,14 in the outside forms overall structure, the 15th, template.This outer insulation construction form is a kind of double load-bearing, insulation, sound insulation is in the body of wall complex heat-preservation system of one, its anti-seismic performance is better than frame construction, thermal and insulating performance has reached 65% energy-conservation requirement of national regulation, can enlarge living space more than 8%, reduce building debris, also solved and generally adopted exterior wall to paste at present, the easy crack that plug-in insulation layer technology produces, hollowing, seepage, hidden danger such as come off, the union insulation, antidetonation, environmental protection, short construction period, technology maturation advanced person, numerous advantages such as cost is low, be applicable to the various forms of dwelling constructions in cities and towns, social benefit and economic benefit are good.

Inboard concrete 14 thickness of body of wall design by force structure, and the concrete thickness of warming plate 13 is relevant with energy-conservation regulation, and the thick concrete 14 of wall outer side 50mm is as the topping of warming plate 13.After this structural form is determined, how to make the thick concrete 12 of wall outer side 50mm build vibration compacting, excessive displacement does not take place in concreting process the warming plate 13 in the middle of the concrete becomes difficult point and key point in the construction.Selection in concreting, construction in the past has whole use without vibration pea gravel concretens to build, and concrete strength does not reach designing requirement when often causing structure detection; There are whole use ordinary concretes to build, often cause the thick concrete cover leakiness of warming plate outside 50mm; For guaranteeing that the topping concrete compaction has the processing mode of slotting at interval on warming plate, cause many heat bridges, weakened the whole structure of insulation.

In view of the built-in heat insulation concrete structure is bigger in warming plate both sides concrete thickness difference, we attempt building the slump 180～200mm with pea gravel concreten at the thick concrete cover of warming plate outside 50mm.Because the influence of intersection abdomen silk is arranged in this layer concrete, and cobble-stone diameter should not be greater than 10mm.Warming plate inner side main body structure uses ordinary concrete to build the slump 180～200mm.So not only guaranteed structural safety but also reduced expenses.

After the concrete allocation plan was determined, concreting method just became the construction principal contradiction.The concreting method of original adoption is: agent structure warming plate both sides ordinary concrete and self-compacting concrete are built simultaneously, adopt the mode of building of material distributing machine and hopper respectively, vibrate in conjunction with the method for carrying out.Ordinary concrete adopts vibrating head to insert and smashes, and self-compacting concrete adopts outer vibrator of mould and rubber hammer to knock auxiliary vibrating.Build highly about 500～600mm height, the height discrepancy in elevation is built less than 200mm in both sides at every turn.But because dissimilar concrete supply times interval problem, two is overlapped the mutual interference problem of concrete equipments, one-time-concreting height control problem makes above-mentioned concreting method implementation result desirable not to the utmost.

Three, utility model content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, can free adjustment pulp position and the concrete aggregate particle diameter of freely controlling the inside and outside height of concreting select separator.

Described sifting barrel is made up of upper and lower side frame and middle screen drum, between the described upper and lower side frame rotating shaft is installed; Described screen drum by screen cloth and up and down the annulus end plate form, described up and down annulus end plate is connected with corresponding upper and lower side frame bolt.

Described screen cloth is made up of axial grizzly bar and radial loop bar.The axis oblique of described axial grizzly bar and described rotating shaft.Perhaps, described screen cloth is made up of the mesh on cylindrical tube and the cylindrical shell.

Described movable outlet pipe is made up of balladeur train and pulp bucket, described balladeur train upper end is provided with and connects the slurry pipe, this connects the slurry pipe and is connected with described screening pipeline rotary type, described balladeur train lower end is provided with slide plate, described pulp bucket is sleeved in the described balladeur train, its bottom contacts with described slide plate, and described pulp bucket rear end is provided with handle.

The grout outlet of described pulp bucket lower chamber is two, lays respectively at the both sides, lower end of lower chamber; Described drive motors is installed on the described pulp bucket.

The beneficial effects of the utility model are:

1, the utility model is reasonable in design; use a cover concrete pump that concrete pump is delivered to and build work plane; lay the concrete aggregate particle diameter at casting position and select separator; concrete pump is selected the separator discharging facing to the concrete aggregate particle diameter; because the effect of screening plant only allows the small particle diameter aggregate concrete to enter thin concrete cover one side, makes big particle diameter aggregate concrete enter thicker deck one side.When the thicker high 200mm of deck one side template inner concrete height of thin concrete cover one side concrete aspect ratio is above, push and separate the pulp slideway, make all concrete all enter thicker deck one side.Utilize and separate pulp slideway free adjustment pulp position, control the inside and outside height of concreting freely, solved construction difficult problem effectively.

2, the utility model making simple in structure, easy, cost are lower, and it is applied widely, has good society and economic benefit.
