Description

Cement built-up shuttering and using method thereof

The present invention relates to a kind of construction work cement built-up shuttering and using method thereof, especially a kind of cement formwork capable of being combined that is applicable to that the monolithic reinforced concrete structure architecture construction is used.

When general construction of buildings body of wall concrete, adopt the manual template formwork that is assembled in usually, or adopt steel, wooden form, or big punching block is made up in advanced typing.With give formulation type wooden model, waste of material is excessive; With the holding capacity deficiency of wooden model, unbalance stress, the yielding and tripe that rises of template; After the form removal, the existence of common quality defects such as revealing muscle, honeycomb is often arranged, the construction works phase is long simultaneously, the cost height, and the wooden model life cycle is short, consumes big, the demoulding has very big difficulty again, is the backward construction technology of a kind of time-consuming, effort, high cost, with steel form or typing combined large steel model formworks such as (China Patent No. 90201809.4), template weight is big, volume is big, price is expensive, the transition of construction point is dumb, after concrete is made, and also must be through operations such as demolition templates, workload is big, the cost height.

The object of the present invention is to provide a kind of prefabricated cement built-up shuttering, use this cement built-up shuttering, strengthened the holding capacity (the crowded power when smashing concrete, the drag of the power of vibrating) of template, improved the quality of concrete watering, a large amount of timber and unit's nail have been saved, simultaneously template directly is applied on the building, need not form removal, and also the template volume is little, in light weight, easy and simple to handle, laborsaving, save time, reduced engineering cost significantly, shortened the construction period greatly.

Above-mentioned purpose of the present invention is achieved in that cement built-up shuttering comprises cast-in-place cement built-up shuttering panel, reinforcing bar, long pin ring and ribbet, cement built-up shuttering is aggregate with the microlith, the reinforcing bar that diameter is about 4 millimeter intersects anyhow to be imbedded in the cement built-up shuttering, according to the maximum load capacity design sandstone ratio and the radical that buries reinforcing bar that gives, in the high 1/3h of the panel position about 10 centimeters from the edge, the right and left is respectively settled a long pin ring symmetrically, collar extension in the same way, the panel bottom of the cement built-up shuttering of using as bottom and the long pin ring on top are set up group leader's pin ring on the symmetrical position, edge, template surrounding is a ribbet, protruding inboard, the ribbet outside, every template top is recessed, and ribbet inboard, bottom is protruding, outer concave, the outside, the ribbet left side, the left and right sides is protruding, and is then recessed in the outside, the right.Every panel area generally is no more than 0.25m ², weight is not more than 12 kilograms, and high h is no more than 40cm, and long L is no more than 60cm, about about 2.5 centimeters of thick a.

During construction, at first according to building shape, size, size and required number of calculating and definite cement built-up shuttering, in case remainder, and by maximum load capacity design sandstone proportioning and the reinforcing bar number of going into to bury, cement built-up shuttering given make, then as building wall, carry out formwork erection, elder generation is first template in corner fixedly, the bottom is firm with cement mortar filling seat, the band one side inwardly, and two template formation inner and outer templates staggered relatively, by the concrete breadth of section iron wire two ends that diameter is about 8 millimeter are curved 90 ° grab, respectively grab is inserted in four group leader's pin rings of inner and outer template, upright good template center of gravity can not be departed from, template is strained, fixing, the ribbet of template will align, coincide, the outside of seam mortar raking treats that the combination of first floor cement built-up shuttering finishes, and can carry out concrete and water the work of smashing, cement is poured between the inner and outer template, and the limit is watered the concrete limit and is vibrated.Suffered crowded power on the template, the shear stress of the power of vibrating and ribbet is all less than the permission power through calculating and designing, so can not produce the tripe that rises, phenomenons such as fission, template and concrete body strike up partnership, after treating that concrete has certain intensity, then carry out the assembling of upper former, arrangement and concrete water the work of smashing, because the protruding inboard, the ribbet outside, upper edge of lower template is recessed and the lower edge outer concave of upper former, inboard protuberance part matches, therefore the center of gravity of upper former can not depart from, and the combinated seam of levels template coincide firmly, and the long pin ring of upper former only needs top to get final product for one group.

The present invention compares with existing wooden form, steel form, combined large steel model, and its advantage has the following aspects.

1. can carry out concrete once and water the work of smashing, need not the form removal operation, save a large amount of manpowers, financial resources, material resources, shorten the duration.

2. the lateral pressure of suffered cement mortar on the panel of cement built-up shuttering, the power of vibrating of vibrator and the shear stress of ribbet are filled Xu Li during all less than design, thus the concrete compactness height of pouring, thus guaranteed the quality of building.

3. save a large amount of timber and unit's nail, reduced construction costs.

4. the cement built-up shuttering volume is little in light weight, and constructing operation is convenient, flexible.

Below in conjunction with drawings and Examples the present invention is described in further detail.

By Fig. 1-Fig. 6 as can be known, be ribbet 4 around the cement built-up shuttering, be convenient to combination, the formwork erection, identical of template.And seam crossing is non-leakage.During prefabricated cement built-up shuttering, at first according to shape, the size of building, the size of size, moulding budget and definite template, in case remainder, the long L of template is 50-60m ², high h is 30-40cm, thick about 2.5cm, and area is no more than 0.25cm ²Weight is not more than 12 kilograms, make aggregate with microlith when every template is prefabricated, with 2 of horizontal strokes, perpendicular 3 left and right sides diameters are about 4 millimeters reinforcing bar 2 and imbed in the panel 1, high 1/3h on panel 1, in about 10 centimeters of two edges, on the position some long pin rings 3 are set, template as bottom, establish the symmetrical position, position of long pin ring on panel 1 bottom and top and set up some long pin rings 3, during construction, by the concrete breadth of section iron wire two ends of 8 millimeter are bent into 90 ° of grabs 5 with iron wire, the two ends crotch is inserted in respectively in the long pin ring 3 of cement built-up shuttering staggered relatively, template is strained, upright jail forms inner and outer template, ribbet will align, the seam of inner and outer template outside tape edge water silt particle slurry raking, clog with cement mortar the bottom, the inner and outer template imprisonment is finished after, can carry out concrete and water the work of smashing, treat that template and the cement that waters down strike up partnership, and after certain intensity was arranged, arrangement and the concrete that can go up face die plate watered the work of smashing.

As run into garden shape, the building of modeling structures such as arc, prefabricated cement built-up shuttering panel is curved, presses the garden radian number of building when calculating in advance, and size calculated radian number and the required number and the size of arc formwork, carries out prefabricated arc cement built-up shuttering.
