Abstract

The utility model relates to a mold for producing a cement prefabricated floor plate through a short line method. The structure of the mold is that a bottom mold is provided with a side mold, an end mold, a steel bar fixed plate, etc. Compared with the existing method of producing the cement prefabricated floor plate through a long line, when used to produce the cement prefabricated floor plate, the utility model has the advantages of land saving, high floor plate quality, low cost, easy maintenance, easy factory operation, flexibility, maneuverability, etc., and the production can be carried out near the building site.

Description

Concrete prefabricated floor short-term mould

The utility model relates to building field, is a kind of short-term mould of producing concrete prefabricated floor that is applicable to.

Along with the development of socialist construction, skyscraper is also rised sheer from level ground like the mushrooms after rain, and the consumption of precast floor slab is very big.To at present, the precast floor slab that China produces all is the method that adopts long line to produce, and promptly on roomy concrete floor the reinforcing bar tensioning is produced in the open.This mode of production not only needs roomy prefabricated place, also needs certain stacking place, otherwise can't produce.In addition: also can have influence on the quality of prefabricated cement floor because of the out-of-flatness in prefabricated place and because operation in the open, meeting burning sun and severe cold just can not all-weather production.In addition: the investment that long line is produced precast floor slab is bigger, example: the production site of building 1000 floors of monthly output needs 300,000 yuan of funds approximately.

The concrete prefabricated floor short-term mould that the utility model proposes can overcome the weak point that long now line is produced concrete prefabricated floor, reaches province ground, investment-saving, guarantees purposes such as the floor quality of production.

Major technique feature of the present utility model is as follows:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the utility model precast floor slab reinforcing bar tensioning schematic diagram

Accompanying drawing 3 is the schematic diagram of precast floor slab stacking on the utility model bed die

Among the figure: 1 be bed die, 2 for the end mould, 3 for side form, 4 for conduit, 5 for the reinforcing bar fixed head, 6 for suspension ring, 7 for lever, 8 for jack, 9 for precast floor slab, 10 for reinforcing bar

As seen from the figure, the utility model by bed die 1, end mould 2, side form 3, conduit 4, Reinforcing bar fixed head 5 forms, and its bed die 1 is posture, on the bed die face both sides arrange side form 3, Top, two ends place be provided with reinforcing bar fixed head 5, inboard, two ends arrange end mould 2, conduit 4 side by side, Parallel cross two the end moulds 2 (seeing Fig. 1). And be provided with suspension ring, bed die on the bed die 1 1 below support height is greater than precast floor slab thickness, and bed die length two ends spacing is 3-5 rice.

Making on request the utility model can come into operation. Earlier equidistant between conduit Put into abreast reinforcing bar, and the tensioning reinforcing bar. During tensioning, fix an end bar, the other end By the tension of the shackle at lever two ends, with same distolateral at bed die of the very heavy topmast of small-sized hydraulic Operate jack, treat that pressure expression regulation tension force gets final product (seeing Fig. 2). The placement side form, Conduit, end mould are poured the cement concrete that mixes by ratio requirement into then in framed, After waiting to solidify, give maintenance according to specification requirement.

Adopt the utility model to carry out short-term template production cement floor and compared following advantage with long line production technology:

One, save the soil: equal production scale, short-term template are produced and are only accounted for long line production and need account for 30% of land area, adopt buttress such as small-sized hoisting machine to pile to the certain height (see figure 3) because of the former, even can be in indoor prefabricated and maintenance.

Two, improve the quality: produce when prefabricated and not influenced by terrace and cause damagedly, because of using this steel die, product quality is guaranteed easily.

Three, cost is low: do not need the construction investment of large tracts of land terrace, and equal production scale, the mould expense only accounts for 33% of long line production investment.

But four factory building equalization, round-the-clock production maintenance.Long line is produced floor, is exposed to fully summer under the burning sun, and crackle easily takes place, need the topped frost-resistant material of large tracts of land winter, the floor that short-term is produced can be concentrated stacking on bed die, be not subjected to tanning by the sun of burning sun, also only need winter an a spot of frost-resistant material just can all cover, save time, laborsaving, water-saving.

Five, maneuverability, the construction site produces nearby, can reduce expensive freight.

To sum up, the utility model production technology is simple, investment is little, good social benefit and economic benefit are arranged, and is suitable for applying.
