Abstract
The utility model belongs to the field of bridge construction, particularly relates to a truss frame type surrounding purlin and no-pull rod rollover device for high tower construction. The device is characterized in that a face plate, facade mold plates, lateral mold plates, a vertical stiffening rib and a truss frame borne by the face plate are included; the face plate and the vertical stiffening rib are welded together to form a quadrangular structure, the two facade mold plates are connected to the front and the back of the quadrangular structure respectively, and the two lateral mold plates are connected to the left side and the right side of the quadrangular structure respectively; an opposite pull rod is arranged between every two of the two ends of the internal booms of the truss frame borne by the facade mold plates and the lateral mold plates for fixation; corbels are welded on the booms; the truss frame borne by the face plate adopts a trapezoidal structure comprising channel steels and I-beams through welding; and the truss frame borne by the face plate is welded outside the vertical stiffening rib. The truss frame type surrounding purlin and no-pull rod rollover device has highly attractive appearance in tower body and pier body construction, and the bar reinforcement is less susceptible to corrosion in the concrete construction.
Description
Technical field
The utility model belongs to field of bridge construction, particularly high tower construction truss-like encloses purlin, no pull bar turning-over, it is applied to have relatively high expectations to attractive in appearance, in the high tower of Deformation control strictness, the work progress of high pier, be a kind of shaped steel in the conventional template to be enclosed the new plate device that purlin replaces with trussed construction.
Background technology
Along with the development of engineering construction, to various high towers, template deformation requirement when high pier not only has concreting, construction period, also more and more stricter to the requirement of the presentation quality of body of the tower, pier shaft, also more and more higher to requirement attractive in appearance.
At present body of the tower, pier construction traditional method are: in the construction of body of the tower, pier shaft adopt pass in the body to drawing the template of rod-pulling type, though this template processing is simple, template is lighter relatively, but formwork integral rigidity is little, need use during construction pull bar, to such an extent as to the concrete surface draw-bar eye is many, handle loaded down with trivial details, concrete surface is not attractive in appearance, and after the pull bar corrosion, will form the corrosion passage of reinforcing bar in the concrete structure, reinforced steel bar rust preventing be had in the engineering of specific (special) requirements inapplicable in ocean engineering or some.
Summary of the invention
The purpose of this utility model provides a kind of high to requirement attractive in appearance in body of the tower, pier construction, and the uncorruptible high tower construction of reinforcing bar truss-like encloses purlin, no pull bar turning-over in the concrete structure.
The purpose of this utility model is to realize like this, high tower construction truss-like encloses purlin, no pull bar turning-over, it is characterized in that: it comprises panel, front face template, Side shuttering, vertical stiffening rib and truss that panel is carried on the back, panel is welded together to form quadrilateral structure with vertical stiffening rib, connect a front face template before and after the quadrilateral structure respectively, about connect a Side shuttering respectively, in the truss of carrying on the back on front face template and the Side shuttering chord member two ends use an angle fastening between any two respectively to pull bar, on chord member, weld bracket; Truss that panel is carried on the back is welded into trapezium structure by channel-section steel and i iron, and truss that panel is carried on the back is welded on the vertical stiffening rib outside.
Described to pull bar two ends band alignment pin and steel bushing.
The utility model characteristics are: 1. template is for every layer to be sized by producer's strictness, and after installing, size is accurate, and error is less, needs the adjustment time of cost few, has improved work efficiency; 2. large form concrete construction seam is few, can better guarantee construction quality, satisfies the requirement of owner's elaboration engineering; 3. the used large-scale truss of template does not need to adopt other steel to reach pull bar, after the form removal, and unmatchful pulling eye on the pier shaft, outward appearance adopts attractive in appearance to the pier shaft of pull bar; 4. whole pier shaft template adopts large-scale truss to do support, has reduced the circulation material that steel pipe and fastener etc. are easily lost.
Description of drawings
Fig. 1 is that the utility model embodiment posture is enclosed purlin stencil plane arrangement diagram;
Fig. 2 is to pulling rod structure figure among Fig. 1;
Fig. 3 is the Side shuttering constructional drawing of Fig. 1.
Among the figure: 1, pier shaft; 2, panel; 3, to pull bar; 4, vertical stiffening rib; 5, truss that panel is carried on the back; 6, front face template; 7, Side shuttering; 8, chord member; 9, bracket.
The specific embodiment
Shown in Figure 1, high tower construction truss-like encloses purlin, no pull bar turning-over comprises panel 2, front face template 6, Side shuttering 7, vertical stiffening rib 4 and truss that panel is carried on the back 5, panel 2 is welded together to form quadrilateral structure with vertical stiffening rib 4, connect a front face template 6 before and after the quadrilateral structure respectively, about connect a Side shuttering 7 respectively, interior chord member 8 two ends of the truss of the back of the body uses an angle fastening to pull bar 3 between any two respectively on front face template 6 and the Side shuttering 7, stressed for ease of pull bar, welding bracket 9 on chord member 8; Truss that panel is carried on the back 5 is by channel-section steel and the i iron trapezium structure that is welded, and truss that panel is carried on the back 5 is welded on vertical stiffening rib 4 outsides.
Fig. 2 is the structural representation to pull bar 3, to pull bar 3 two ends band alignment pin and steel bushings, connection front face template 6 and position and bolt during Side shuttering 7.
As shown in Figure 3, Side shuttering 7 is made up of panel 2, vertical stiffening rib 4, chord member 8, truss that panel is carried on the back 5, and panel 2 welds together with vertical stiffening rib 4, and truss that panel is carried on the back 5 is welded on vertical stiffening rib 4 outsides.Trussed construction increases the rigidity of template, makes it not yielding.Truss that panel is carried on the back 5 is welded into trapezium structure by channel-section steel and i iron, and the trapezium structure both sides extend chord member 8 to the outer.For ease of stressed to pull bar 3, welding bracket 9 on chord member 8.
After the template piecemeal machined, by the assembly unit serial number, and the examination before successively precasting yard dispatches from the factory was successively pieced together.
1) concrete is interior has simplified traditional construction technology to wearing pull bar to truss type formwork owing to noting be used in, and has shortened construction period.It is comparatively convenient, workable that truss type formwork is installed, adjusts, removed.
2) the truss type formwork integral rigidity is big, is out of shape for a short time, saves template up and down and connects with shaped steel, and formwork integral is stressed evenly.Build the concrete structure of shaping, surfacing, attractive in appearance with truss type formwork.
3) truss type formwork is because the existence of no draw-bar eye has been eliminated under marine environment, and wave spatters and the corrosion passage of atmosphere unfavorable conditions to pier shaft inside reinforcing bar, meets the life requirement of works.
