Abstract
The invention discloses a cast-in-place box girder formwork diagonal bracing device. The case-in-place box girder formwork diagonal bracing device comprises a main back bar, wherein a gap is formed between the main back bar and a supporting cross section and is filled with square timbers; the main back bar is an inclined '['-shaped support; the inside of the main back bar is supported by a three-section diagonal bracing; the three-section diagonal bracing consists of retractable diagonal bracing pieces and a main diagonal bracing piece; the retractable diagonal bracing pieces are mounted at two ends of the main diagonal bracing piece and are retractable; and a vertical supporting seat is arranged on a ground vertical section of the main back bar. The cast-in-place box girder formwork diagonal bracing device is simple in structure; and shortcomings that the traditional cast-in-place box girder formwork system is supported by a profile steel truss, a web formwork is provided with opposite-pull rods, a large amount of steel needs to be consumed, machining, conveying, mounting and dismounting costs are high, and transferring use ratio is low are overcome.
Description
Technical field
The present invention relates to cast-in-situ box girder template construction field, a kind of cast-in-situ box girder template bracing device is provided.
Background technology
Traditional cast-in-situ box girder template system adopts steel truss to support, and web templates establishes the form to pull bar.Need at substantial steel, and processing, transport, peace split into that this is all comparatively large, turnover utilization rate is low; All need Large-scale Hoisting equipment coordinating operation during installation and removal, peace tears very inconvenience open; Web templates arranges pull bar, and construction clashes with prestressing force position often, and need to change draw rod positions at any time, cause form cycling rate low, concrete appearance is poor, also needs to repair tie rod hole after form removal.
Summary of the invention
The object of the present invention is to provide a kind of cast-in-situ box girder template bracing device.
Object of the present invention can be achieved through the following technical solutions:
A kind of cast-in-situ box girder template bracing device, comprise main back cord, between described main back cord and support section, there is space, the lumps of wood is filled up in space, described main back cord be tilt " [" type support, it is inner relies on three sections of diagonal braces to support, and described three sections of diagonal braces comprise flexible bracing element and main brace part composition, it is scalable that described flexible bracing element is arranged on main brace part two ends, and described main back cord ground vertical section is provided with vertical holder.
Described three sections of diagonal braces and main back cord are bolted.
Described three sections of diagonal braces have multiple, and different angles of inclination is supported in main back cord.
Beneficial effect of the present invention: structure of the present invention is simple, solving traditional cast-in-situ box girder template system adopts steel truss to support, web templates establishes the form to pull bar, need at substantial steel, and processing, transport, peace split into that this is all comparatively large, the drawback that turnover utilization rate is low, saves material, reduce processing, transport and peace and split into this, improve support system turnover utilization rate; Improve template turnover utilization rate, improve Surface Quality of Concrete; Construction weight is less, does not need Large-scale Hoisting equipment to coordinate, and it is simple, easy to operate, safe and reliable that peace tears operation open.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind of cast-in-situ box girder template bracing device, comprise main back cord 1, between described main back cord 1 and support section 2, there is space, the lumps of wood 8 is filled up in space, described main back cord 1 is " [" type support tilted, its inner dependence three sections of diagonal braces 5 support, described three sections of diagonal braces 5 comprise flexible bracing element 3 and main brace part 4 forms, it is scalable that described flexible bracing element 3 is arranged on main brace part 4 two ends, described main back cord 1 ground vertical section is provided with vertical holder 7, described three sections of diagonal braces 5 are connected by bolt (6) with main back cord 1, described three sections of diagonal braces 5 have multiple, different angles of inclination is supported in main back cord 1.
During use, female main brace part 4 (diagonal brace outer tube) and flexible bracing element 3 (diagonal brace adjusting screw(rod)) will be with to fit together, by main brace part 4, adjustable diagonal brace system length.During cast-in-situ box girder template construction, together with first diagonal brace system two ends being bolted with the main back cord of box girder formwork, then according to case beam formwork erection size, main brace part 4, adjustment diagonal brace length, then installation form system.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
