Abstract

The invention provides a method for on-site wall pouring without form removal, and effectively solves the problems that existing on-site gypsum forming needs continuous form removal and installation, slurry leaks and the like. The technical scheme includes that slurry is conveyed to a fixed mould box, the fixed mould box moves upwards to perform demoulding when the slurry is in initial setting as the slurry is easy to demould when in initial setting, the fixed mould box moves upwards to a wall after initial setting and takes the initial setting wall as a bottom, the slurry is continued to be conveyed to the fixed mould box, the operation is repeated until the wall reaches needed height, the fixed mould box moves backwards out of the poured wall when the wall reaches the needed height, the fixed mould box moves again to the bottom and is in butt joint with the poured wall, and pouring is continued. The method overcomes the defects of leakage of original on-site gang form pouring, time waste of form removal and installation and the like, the wall is high in strength and flatness, and cost is reduced.

Description

A kind ofly exempt from the method that the form removal cast-in-site becomes wall

Technical field

The present invention relates to the body of wall forming method, particularly a kind ofly exempt from the method that the form removal cast-in-site becomes wall.

Background technology

Gypsum is the natural resource of having many uses, building materials of gypsum has lightweight, high-strength, advantage such as energy consumption is low, the hardenite dimensionally stable is good, harmless, be the green construction material of praising highly development in the world, therefore use very general in many countries and regions; At present, the gypsum in-place forming mostly is to need into the position of wall by size and the thickness assembled formwork of body of wall in building, and then slip annotated to the template chamber, by the time carry out form removal after slip solidifies again, this kind method, need at the construction field (site) constantly form removal dress mould, the spillage problem is serious, waste time and energy.

Summary of the invention

At above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just provides a kind of method that the form removal cast-in-site becomes wall of exempting from, and has effectively solved existing gypsum in-place forming and has wanted problems such as continuous form removal dress mould, spillage.

The technical scheme of its solution is may further comprise the steps:

(1) slip parameter time of setting is tested;

(2) in building, need into fixing size and the thickness ready-made fixedly moulding box in advance according to required body of wall in the position of wall, this fixedly moulding box facing to an end, the top and bottom opening of building masonry wall, after fixing template, building masonry wall, building bottom surface and fixedly form only upper end open between the moulding box, the space of other end face sealing;

(3) preparation slip;

(4) slip is delivered to fixedly moulding box, because be easy to the demoulding during slip initial set, so moving up fixedly when treating the slip initial set, moulding box carries out the demoulding, fixedly moulding box is moved upwards up on the initial set body of wall, this moment, fixedly moulding box was the bottom surface with the initial set body of wall, continuation is delivered to fixedly moulding box with slip, repeats above work, reaches the height that needs until body of wall;

(5) reach when needing height when body of wall, fixing moulding box is shifted out the body of wall of having poured into a mould backward, fixedly moulding box re-moves the bottom surface, with fixing moulding box butt joint cast body of wall well, proceeds to pour into a mould;

(6) repeat above cast step, till pouring into a mould good required body of wall fully;

(7) after the body of wall completion, repair the body of wall joint with the filleting land plaster.

The invention solves the spillage of original cast-in-place shaping gang form, waste man-hour of dismounting template etc. defective, and strength of wall body is big, the planeness height has reduced cost.

The specific embodiment

Below the specific embodiment of the present invention is described in further detail.

A body of wall is poured into a mould at embodiment 1 scene in the open-air enclosure wall place of a long 9000mm, the high 3200mm of wide 5000mm, the place every the space that is set to two long 9000mm, the high 3200mm of wide 2500mm, is needed the long 9000mm of body of wall, the high 3200mm of thickness 100mm of cast.

(1) the quality proportioning mixing according to 65 moisture and 100 gypsum obtains the gypsum slip that sub-fraction is used for testing, and the gypsum slip is tested time of setting, and obtaining the result is to be 8 minutes in the slip initial setting time, and final setting time is 12 minutes.

(2) make the fixedly moulding box of the high 400mm of the wide 100mm of what a long 600mm, this is moulding box front end, lower end and upper end open fixedly, with fixing moulding box front opening place to place in the middle of the body of wall medial surface of spreading 9000mm, fixedly ground, enclosure wall place is docked in the moulding box lower end, fixedly the side of moulding box is fixed on the hoist, implements the fixedly lifting of moulding box with hoist, and hoist is fixed on the traversing carriage, be used for mobile moulding box, realize fixedly moving horizontally of moulding box.

(3) the quality proportioning mixing according to 65 moisture and 100 gypsum obtains slip.

(4) slip is injected fixedly moulding box from the opening part of fixing moulding box upper end, stop cast when treating slip casting to 2-3mm place, fixed distance moulding box upper end open place, when waiting for 8 minutes, the slip initial set, because be easy to the demoulding during slip initial set, so moving up fixedly during the initial set of cast slip, moulding box carries out the demoulding, fixing moulding box is moved upwards up on the body of wall of initial set, this moment, fixedly moulding box was the bottom surface with the initial set body of wall, continuation is delivered to fixedly moulding box with slip, the moulding box that moves up repeats above work, reaches the height that needs until body of wall.

(5) reach when needing height when body of wall, fixing moulding box is shifted out the body of wall of having poured into a mould backward, fixing moulding box is re-moved the bottom surface of open-air enveloping field, body of wall is well poured into a mould in fixing moulding box front opening place butt joint, proceed to pour into a mould.

(6) repeat above cast step, till having poured into a mould body of wall fully.

(7) after the body of wall completion, repair the body of wall joint with the filleting land plaster, filleting gypsum mealiness energy index: meet standard JG/T3049-1998.

Claims

1. exempt from the method that the form removal cast-in-site becomes wall for one kind, may further comprise the steps:

(1) slip parameter time of setting is tested;

(3) preparation slip;
