Background technology
According to the feature of China's building operations, in the contingent security incident of building-site, formwork bracing system unstability cave-in accident odds is comparatively large, and the personnel's injury caused, property loss, operating environment destroy the most serious, have been listed in the significant risk factor of construction work.
Occur for formwork bracing system unstability cave-in accident, counter-measure conventional at present mainly contains following several method:
(1) reliable connection is done with existing structure.
(2) control support structure height is not more than 3 times of braced structures transverse width.
(3) cable wind rope of lower end and earth anchor drawknot is symmetrical arranged on the support structure.
(4) throwing support is symmetrical arranged on the support structure.
But there is following problem in above-mentioned several method:
1, for newly placed concrete cantilevered structure, because falsework three limit is without reliable connection, measure (1) is also inapplicable.
2, in order to meet the requirement that falsework depth-width ratio is not more than 3, need increase the scope on support body transverse width and support post basis, foundation soil should carry out cure process simultaneously.Which is for newly placed concrete cantilevered structure, and when cantilever span is less than 2.7m, when support structure height is more than 15 meters, the increase of measure 2 cost is higher.
3, in order to meet the requirement that falsework depth-width ratio is not more than 3, when taking to reduce falsework height, in the described lower floor of newly watering cantilevered structure, overhang steel platform need be set and carry out support shuttering support.The method complex structure, calculate loaded down with trivial details, be inconvenient to construct, if the inconsiderate impact that can cause crack on agent structure.
4, measure (3), measure (4) are comparatively applicable to the high-order braced structures of independence of ward.
Utility model content
The utility model object provides a kind of cantilevered structure formwork bracing system to overcome the deficiencies in the prior art, its simple structure, economical rationality, convenient construction, and the stability of newly placed concrete falsework in building operations can be strengthened, reduce construction safety hidden danger.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cantilevered structure formwork bracing system, comprise side and be arranged on cantilevered structure on body of wall, described formwork bracing system is for supporting cantilevered structure, be arranged on the below of cantilevered structure, described formwork bracing system comprises the wall-connecting piece of falsework, falsework and body of wall, wire rope and anchor ring; Described anchor ring anchors on body of wall; Described wire rope is plane splayed, and in same level, wire rope need be symmetrical arranged; Described wire rope inclined-pulling angle is at 45 ° ~ 60 °, and the bolt tensioning that what one end and wire rope adapted be arranged on falsework, the other end and described anchor ring carry out level and socket.
Improve further as the utility model, described falsework comprises vertical bridging and horizontal cross brace, and surrounding has and is reliably connected with body of wall, and its excess-three limit is connected without reliable with body of wall.
