At present, domestic huge Structural Steel Reinforced Concrete construction often adopts the construction technology of combined steel formwork.But, steel form to purchase one-time investment comparatively large, the cost recovery cycle is long, and thus, use during combined steel formwork and must strengthen maintaining to it, accelerate turnover, increase access times, to improve its economic benefit.

In view of steel form cost is high, disposablely to have high input, thus, in the engineering of, template circulation difficulty tight in the duration of a project, often do not adopt combined steel formwork.The loose template system torn wooden form open and coordinate double flute steel joist of loose spelling how can be adopted in this type of engineering.

Compared with existing steel template system, the construction Difficulties of heavy in section vertical structure template is, the external corner consolidation process relative difficulty of its wooden form, and its construction quality is difficult to obtain guarantee, and this is one always problem to be solved.

Utility model content

For overcoming the defect existing for prior art, now providing a kind of external angle formwork oblique pull fastener, to solve the fastening problem of heavy in section template external corner, improving efficiency of construction further, the reduction of erection time, reduce construction cost.

For achieving the above object, provide a kind of external angle formwork oblique pull fastener, external angle formwork comprises wooden form and the vertical lumps of wood, and the many vertical lumps of wood are evenly arranged in outside wooden form, and this oblique pull fastener includes:

Head and the tail enclose many keel outside the vertical lumps of wood, the two ends of every root keel have respectively for wear every absolutely empty;

Multiple Triangulums of hollow, outside the two ends being fixed in keel respectively, each Triangulum comprises the joint face favouring keel external surface;

Backing plate, is arranged at joint face;

Connecting screw rod, two ends be each passed through adjacent two keel ends every absolutely empty and Triangulum so that be fastenedly connected with backing plate.

The beneficial effect of the utility model external angle formwork oblique pull fastener is,

Utilize keel two ends to design every absolutely empty, fit through multiple Triangulums of hollow, by fastening for connecting screw rod drawknot in the head and the tail joint enclosing keel, achieve the construction that heavy in section template external corner is fastening simply efficiently.

Preferably, every root keel comprise at least two folded every dead level up and down channel-section steels, and then the two ends of keel are formed respectively every absolutely empty.

Preferably, each Triangulum comprises the set square of at least two pieces of bendings, one piece of set square is set up respectively every the both sides of absolutely empty, every block set square comprises the first supporting surface and second supporting surface of bending mutually, first supporting surface is erected in the external surface of keel, and then second supporting surface favour the external surface of keel, form joint face by the second supporting surface laid respectively at every absolutely empty both sides.

Preferably, backing plate offers perforation, perforation corresponds to every absolutely empty, and connecting screw rod is bored a hole and to pass through nut in addition fastening.

Detailed description of the invention

For the benefit of to the understanding of structure of the present utility model, be described below in conjunction with drawings and Examples.

With reference to Fig. 1, it is the overall structure schematic diagram of the utility model external angle formwork oblique pull fastener.With reference to Fig. 2, it is the close-up schematic view of a-quadrant in Fig. 1.

Shown in composition graphs 1 and Fig. 2, the utility model provides a kind of external angle formwork oblique pull fastener, wherein, external angle formwork comprises wooden form 1 and the vertical lumps of wood 2, the many vertical lumps of wood 2 are evenly arranged in outside wooden form 1, above-mentioned oblique pull fastener includes: head and the tail enclose the many keel 3 outside the vertical lumps of wood 2, the two ends of every root keel 3 have respectively for wear every absolutely empty 30; Multiple Triangulums 4 of hollow, outside the two ends being fixed in keel 3 respectively, each Triangulum 4 comprises the joint face 40 favouring keel 3 external surface; Backing plate 5, is arranged at joint face 40; Connecting screw rod 6, two ends are each passed through and are fastenedly connected with backing plate 5 every absolutely empty 30 and Triangulum 4 and then by adaptive nut 7.

With reference to Fig. 3, be Fig. 2 intermediate cam seat and keel connecting structure enlarged diagram.As shown in Figure 3, comparatively preferably, every root keel 3 comprise at least two channel-section steels 32 folded every dead level up and down, and then the two ends of keel 3 are formed respectively every absolutely empty 30.Wherein, stay tube 34 can be set firmly with firm formed every absolutely empty 30 between two channel-section steels 32, and backing plate 5 offers perforation 50, perforation 50 corresponds to every absolutely empty 30, and connecting screw rod 6 is through this perforation 50.

With reference to Fig. 4, it is the structural representation of Fig. 3 intermediate cam seat.As shown in Figure 4, preferably, each Triangulum 4 comprises the set square 42 of at least two pieces of bendings, one piece of set square 42 is set up respectively every the both sides of absolutely empty 30, every block set square 42 comprises the first supporting surface 420 and the second supporting surface 422 of bending mutually, first supporting surface 420 is erected in the external surface of keel 3, and then the second supporting surface 422 favours the external surface of keel 3, forms joint face 40 by the second supporting surface 422 laid respectively at every absolutely empty 30 both sides.

After having said structure feature, the utility model can by following implementation Process:

As Fig. 2, the many vertical lumps of wood 2 are set outside the wooden form 1 that four sides encloses.Two channel-section steels 32 are folded to form keel 3 every dead level dorsad, many keel 3 level is enclosed outside the vertical lumps of wood 2.

With reference to Fig. 5 to Fig. 6, it is the view that Fig. 4 intermediate cam seat substep makes.Shown in composition graphs 5 and Fig. 6, select existing channel-section steel structure respectively through twice oblique cutting to form the set square 42 of above-mentioned vertical bending.

As Fig. 3 and Fig. 4, respectively set square 42 is erect outside the two ends being welded in keel 3.Utilize bending set square 42 the second supporting surface 422 wherein to coordinate in the both sides every absolutely empty 30 and form joint face 40.Backing plate 5 is arranged on joint face 40.

Look back Fig. 2, the two ends of connecting screw rod 6 are each passed through adjacent two keel ends every absolutely empty 30 and Triangulum 4, and then to be fastenedly connected with backing plate 5 by adaptive nut 7.

With this, the end of adjacent two keel is fastenedly connected.By that analogy, what complete all keel is fastenedly connected work to other keel.

Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain.
