Description
Technical field
The present invention relates to a kind of formwork suspending method of heating furnace top.
Background technology
In top plastic material work progress in the past, the general common scaffold formwork (supporting moldable) that adopts, the full hall of scaffold is supported on the interior brace summer of stove, people's operating space is less during moldable the construction, be easy to generate the mould phenomenon that expands in the work progress, moldable work plane is difficult to handle after the form removal, often exceeds code requirement.Relatively more chaotic in the burner hearth during form removable, security incident takes place easily, and other operations work (as brace summer wrapping, masonry of well etc.) can't be carried out simultaneously during the furnace roof construction.
Summary of the invention
The method that the object of the present invention is to provide a kind of heating furnace top plastic material to hang mould, this method is simple, and other operation operations in the stove can intert synchronously constructs.
To achieve these goals, the technical solution used in the present invention is: heating furnace top plastic material hangs the method for mould, it is characterized in that it comprises the steps:
1) confirms that one by one the equal spot welding of i iron of hanging on the beam is fixed on the furnace roof crossbeam; Prepare at least 4 and hang mould, each hangs mould by pull bar, upper cap nut, upper gasket, steel plate pad, flitch, butterfly card, following nut, lower gasket are formed;
2) vertically establish along stove and hang set of molds, each hangs set of molds and has at least 2 to hang mould; Hang set of molds along horizontal at least 2 groups (promptly hanging mould to installation in length and breadth) of stove along stove; It is as follows that each hangs the mounting method of mould:
1. will to the upper end of pull bar pass successively on the flitch on pull bar through hole, the steel plate pad to putting upper gasket behind the pull bar through hole and screwing on upper cap nut; Flitch is shelved on the adjacent i iron;
2. will to the bottom of pull bar pass on the butterfly card to putting lower gasket behind the pull bar through hole and screwing on down nut;
3) building steel tube vertically is installed on the same butterfly card that hangs set of molds along stove; Or/and nut down, make the thickness of the end face absolute altitude=moldable bottom absolute altitude-steel form of building steel tube by regulating to the upper cap nut on the pull bar;
4) laterally be shelved on building steel tube on along stove steel form;
5) pile up on the steel form moldable, after the moldable ramming in the steel form scope is finished, next piece steel form is installed, continue to carry out cloth, ramming, finish until moldable cloth, ramming by moldable construction technology.
Each hangs adjacent hanging between the mould at a distance of 1.5m in the set of molds, and adjacent hangs between the set of molds at a distance of 1.5m (promptly being 1.5m to the adjacent mold interval that hangs in length and breadth along stove).
Compared with prior art, the invention has the beneficial effects as follows:
One. adopt said method, method is simple, and the steel form mounting or dismounting are simple; Because the assembling and disassembling of steel form of the present invention all can be finished voluntarily by moldable ramming personnel, steel form can not produce down around, so the present invention's bloated mould can avoid moldable construction the time when rigidity of steel form had guaranteed moldable construction;
They are two years old. and during because of existing employing scaffold, out-of-flatness appears in the bad control of absolute altitude of a lot of steel pipes easily.And after the present invention adopts suspension type, do not have scaffold below the steel form, and improving moldable surface finish and impression after the form removal, moldable work plane finishing is convenient after the form removal;
They are three years old. because the present invention adopts suspension type, do not have scaffold below the steel form, promptly have living space below the steel form; Therefore other operation operations in the stove of the present invention can intert synchronously and construct, and form continuous productive process, the raising work efficiency.
Description of drawings
Fig. 1 is the present invention's furnace roof profile in moldable when construction.
Among the figure: 1-is to pull bar; 2-upper cap nut (and upper gasket); 3-steel plate pad; The 4-flitch; The 5-building steel tube; 6-butterfly card; The 7-steel form; The 8-i iron, nut under the 9-(and lower gasket), 10-is moldable, and 11-hangs beam.
The specific embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, heating furnace top plastic material hangs the method for mould, and it comprises the steps:
1) confirms that one by one the i iron 8 equal spot welding of hanging on the beam 11 are fixed on (being the strong point that i iron can be used as suspension) on the furnace roof crossbeam; Preparation hangs that mould is some [to be generally open hearth top area (m
2) ÷ (1.5m * 1.5m) individual], each hangs mould by pull bar 1, upper cap nut 2, upper gasket, steel plate pad 3, flitch 4, butterfly card 6, following nut 9, lower gasket are formed;
2) hang mould to installation in length and breadth along stove, be 1.5m[and vertically establish along stove and hang set of molds to the adjacent mold interval that hangs in length and breadth along stove, each hangs set of molds and has at least 2 to hang mould; Hang set of molds along horizontal at least 2 groups (only drawn among Fig. 12 groups and hung set of molds) of stove; Each hangs adjacent hanging between the mould at a distance of 1.5m in the set of molds, and adjacent hangs between the set of molds at a distance of 1.5m];
It is as follows that each hangs the mounting method of mould:
1. will to the upper end of pull bar 1 pass successively on the flitch 4 on pull bar through hole, the steel plate pad 3 to putting upper gasket behind the pull bar through hole and screwing on upper cap nut 2 (upper gasket between upper cap nut and steel plate pad, upper end, the bottom of pull bar 1 being equipped with external screw thread); Flitch 4 is shelved on the adjacent i iron 8 [flitch 4 by 1.5m * 1.5m arrange (be at a distance of 1.5m * 1.5m) between the adjacent flitch 4];
2. will to the bottom of pull bar 1 pass on the butterfly card 6 to putting lower gasket behind the pull bar through hole and screwing on down nut 9 (lower gasket is down between nut and the butterfly card);
3) building steel tube 5 vertically is installed on the same butterfly card 6 that hangs set of molds along stove; By regulating, make the thickness of the end face absolute altitude=moldable bottom absolute altitude-steel form 7 of building steel tube 5 to upper cap nut on the pull bar 12 and following nut 9;
4) steel form 7 laterally is shelved on [be shelved on the adjacent building steel tube 5, the left and right directions among Fig. 1 is that stove is horizontal, and steel form 7 is installed a row (row has M/1.5 steel form 7, and wherein M is that stove is wide) along the stove cross direction] on the building steel tube 5 along stove
5) pile up on the steel form 7 moldable 10, after the moldable ramming in steel form 7 scopes is finished, next piece steel form is installed, is continued to carry out cloth, ramming (can satisfy construction requirement by that analogy), finish until moldable 10 clothes, ramming by moldable construction technology.
After moldable 10 constructions are finished, steel form removes, the processing method of circular hole to pull bar 1 row in moldable: owing to moldablely have plasticity, remove the moldable filling and repairing that carries out of the available Xin Kaibao in back at steel form, but this work must be carried out in two hours after form removal, in order to avoid influence adhesion strength.
Described diameter phi 20mm to pull bar 1.The height of flitch, widely, long be 60mm * 80mm * 450mm.
