Abstract
The invention discloses a construction method for a cylindrical thin-walled concrete wall template. The method comprises the following steps of: placing an inner support in an inner ring of an inner template to reinforce and adjust the inner template, arranging an outer hoop at the periphery of an outer template, arranging a limiting support between the inner and outer templates to control the relative size and position of the inner and outer templates, and controlling the steadiness of the templates under the combined action of the inner support, the outer hoop and the limiting support. The construction method is simple, low in cost, convenient in construction and good in template stability, and improves the labor condition of construction personnel. The method is particularly suitable for concrete cylindrical machine piers of hydraulic generators of hydropower stations, air cover walls, and cylindrical thin-walled concrete buildings with inside diameter of less than 10M and the like.
Description
Technical field:
The present invention relates to the job practices of the realm of building construction drum type brake thin wall concrete wall form, be particularly useful for power station hydrogenerator concrete cylinder machine pier and fan housing wall, cylindrical shape building.
Background technology:
At present, the most frequently used reinforcement means of drum type brake thin wall concrete wall form construction is the mode that adopts symmetrical tie rod to reinforce.The tie rod contraposition difficulty of the inside and outside template of this kind job practices, the constructor need get into the position operation that reinforcing bar is intensive, built-in fitting is many, the space is narrow and small, operating difficulties, template correction reinforcement amount is big.
Summary of the invention:
The objective of the invention is in order to overcome the deficiency of existing drum type brake thin wall concrete wall construction technology; Provide that a kind of job practices is simple, form stable property is good, with low cost, construction is convenient, improved the job practices of the cylinder thin wall concrete wall form of constructor's condition of labor.
The objective of the invention is to realize like this:
The job practices of drum type brake thin wall concrete wall form of the present invention; This method is that interior support is placed ring reinforcing and adjusting inner formword in the inner formword; Hoop outside on the exterior sheathing neighboring, being provided with; Limited support is set between inside and outside template controls relative size position between inside and outside template, interior support, hoop and limited support synergy control template is firm outward.
Job practices of the present invention specifically comprises the steps:
1) preparation of construction: the inside and outside circular arc of making inside and outside template is respectively enclosed purlin, and every inside and outside panel is separately fixed at inside and outside enclosing on the purlin, forms the inside and outside template of distinguish; Make outer hoop with reinforcing bar and flower basket bolt;
2) construction lofting: emit earlier the end mouth structure line of inside and outside template with total powerstation, every 2-3m spacing is put a point, the fixing end mouth limited support in the bottom of body of wall, and the two ends of limited support flush with the inside and outside structure line of template;
3) inner formword is installed: the first segment inner formword of distinguish is set up in the template after in place support.
4) exterior sheathing is installed: the first segment exterior sheathing of distinguish is in place, vertical steel pipe is installed outside template, hoop outside install in the steel pipe outside is installed the limited support suitable for reading of first segment template;
5) formwork reinforcement and adjustment: support in the adjusting of symmetry simultaneously and outer hoop, accomplish the reinforcing and the adjustment of template, repeat above-mentioned 3) and 4) step, the second joint template is connected with the first segment template, up to the construction of accomplishing whole template;
6) form removal: after concreting is accomplished, loosening interior support and flower basket bolt, promptly dismountable inside and outside template.
Advantage of the present invention: inner formword and exterior sheathing installation and removal are easy, and construction is disturbed few; Exterior sheathing can put in place under the effect of limited support in disposable adjustment reinforcing.The interior support with outer bound round adjusting easily, and be easy to operate; Job practices of the present invention is simple, with low cost, form stable property is good, the distortion is little, has improved constructor's condition of labor.The present invention is specially adapted to power station hydrogenerator concrete cylinder machine pier and fan housing wall, the following drum type brake thin wall concrete of internal diameter 10M works etc.
Description of drawings:
Fig. 1 is the construction process figure of drum type brake thin wall concrete wall of the present invention
Fig. 2 is a drum type brake thin wall concrete wall form structure vertical view of the present invention.
Fig. 3 is that exterior sheathing of the present invention binds round the reinforcing expanded view outward.
The specific embodiment:
Referring to Fig. 1～Fig. 3, the construction method step of present embodiment drum type brake thin wall concrete wall is following:
1) preparation of construction: preparation of construction mainly be support in making 2 with outer hoop 6, inner formword 1, exterior sheathing 4: make inside and outside circular arc respectively and enclose purlin, every inside and outside panel is separately fixed at inside and outside enclosing on the purlin, inner formword 1, the exterior sheathing 4 of formation distinguish.The size of inner formword 1, exterior sheathing 4 will be convenient to transportation and constructor's operation.Template is earlier in factory's group circle inspection; With the outer hoop 6 of the long 2-3m of Φ 8-Φ 12 reinforcement fabrications, bind round 6 two ends outward and respectively process an annulus, be beneficial to flower basket bolt 5 and be connected.Interior 2 general channel-section steel or the steel pipe manufacturings of adopting that support, an end or two ends are provided with the bolt of adjustable length.
2) construction lofting: earlier emit the inside and outside end mouth structure line of body of wall with total powerstation, per 2-3m spacing is put a point, can be with the arc plate external and internal compositions sideline of drawing by layout point.The fixing end mouth limited support 7 in the bottom of body of wall, the two ends of limited support 7 flush with body of wall external and internal compositions sideline.Inspection end mouth elevation, mouth at the bottom of the employing cement mortar screeding.
3) inner formword is installed: the first segment inner formword 1 of distinguish is round with regard to hyte, support 2 in setting up.
4) exterior sheathing is installed: the first segment exterior sheathing 4 of distinguish is round with regard to hyte, vertical Ф 48 steel pipes 3, the spacing 1-2m of steel pipe 3 are installed outside exterior sheathing 4; In steel pipe 3 outsides outer hoop 6 is installed, is bound round the 6 formation closed loops that link to each other with flower basket bolt 5 outward, the limited support 7 that mounting template is suitable for reading; Limited support 7 is direction towards the center of circle; But progressively adjust the outer hoop 6 of flower basket bolt 5 degrees of tightness, support 2 screw rod simultaneously in the adjustment, until inner formword 1, exterior sheathing 4 passed examinations.Downward slippage when preventing that outer hoop 6 is fastening is welded a U type ring at the sidewall of steel pipe 3, will bind round outward to be put in the U type ring.
5) repeat above-mentioned 3) and 4) construction sequence, with second the joint template be connected with the first segment template, with same way up to the completion whole template construction.
6) form removal: after concreting is accomplished, support in loosening 2 with the dismountable inner formword in flower basket bolt 5 backs 1, exterior sheathing 4.
According to the construction needs, interior support can be adopted meter font or intersecting parallels and stable bent structure.
The foregoing description is that foregoing of the present invention is further described, but should this scope that is interpreted as the above-mentioned theme of the present invention only not limited to the foregoing description.All technology that realizes based on foregoing all belong to scope of the present invention.
