Abstract
The utility model relates to an improved template reinforcing bolt belonging to the technical field of building apparatus and is used for providing a template reinforcing bolt that can accelerate construction progress, save raw steel material and guarantee construction quality of a wall body; the technical scheme thereof is as follows: the improved template reinforcing bolt comprises a tightening fastener, a fastening nut, two external screws, two nuts with conical heads and an internal screw, wherein two ends of the external screws and the internal screw are provided with threads, two ends of the internal screw are respectively connected with the two nuts with conical heads, the other end of the screw hole of each nut with conical head is connected with one external screw, and the other end of the external screw is connected with the fastener and the fastening nut. After the template reinforcing bolt is adopted, the bolt can replace a template propping roller, and width between templates can be accurately guaranteed by adjusting the screwing position of the nut with conical head and the internal screw, thus overcoming the defects of hard control of size of the template propping roller, great construction difficulty and easy displacement and deflection; after concrete casting, the external screws and the internal screw can be taken out for repeated use, thus saving raw steel material and reducing cost.
Description
Technical field
The utility model relates to a kind of bolt of reinforcing construction formwork, belongs to the construction equipment technical field.
Background technology
In building operations, all need build template during the outer wall of basement cast in both sides, the structure of general template is: contacted at innermost layer and casting cement is plank, and plank has the flitch of upright arrangement continuously outward as support, and flitch has horizontal steel pipe that flitch is connected as one outward.There is the backform rod relative plank centre, both sides, and the backform rod is a reinforcing rod, withstands in the middle of the plank of both sides, and its length is the wide of cast.Also have set bolt between the steel pipe of both sides, set bolt passes outermost steel pipe, middle plank, the steel pipe on opposite, by fastener and nut tension.Like this, set bolt and backform rod are just fixed construction formwork, and the width in the middle of it between plank is exactly the thickness of wall body of cast.Have following shortcoming in this construction: at first, can't take out behind the set bolt casting cement, bolt can not reuse; Secondly, the inboard need of wall form placed a large amount of backform rods, causes the reinforcing bar waste; Have, backform rod placement difficulty is bigger again, and construction is slow, and backform rod size is difficult to control and the backform rod tilts easily, makes template extruding backform rod cause the wall section size to reduce when the nut screwing clamping of set bolt easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of shortcoming that can overcome prior art, the formwork reinforcement bolt of accelerating construction progress, saving steel, assurance wall construction quality.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved formwork reinforcement bolt, it comprises outer fastening fastener and the clamp nut of template, its improvements are, it also has two external screw rods, two conehead nuts, an inner screw, all there is screw thread at the two ends of external screw rod and inner screw, the two ends of inner screw connect two conehead nuts respectively, and the other end of each conehead nut screw connects an external screw rod, the other end connection fastener and the clamp nut of external screw rod.
Above-mentioned improved formwork reinforcement bolt, the screw thread of described clamp nut, conehead nut, external screw rod, inner screw all mate mutually.
After adopting this formwork reinforcement bolt, can replace the backform rod by this bolt, the screwing the position and can accurately guarantee width between template of cone governor head nut and inner screw, overcome the defective that backform rod size is difficult to control, difficulty of construction is shifted deflection greatly, easily, external screw rod and conehead nut can also take out repeated use behind casting cement, save steel, reduced cost.
Description of drawings
Fig. 1 is a use schematic diagram of the present utility model.
Mark is as follows among the figure: external screw rod 1, steel pipe 2, conehead nut 3, steel plate for sealing water 4, inner screw 5, overlay film composite board 6, flitch 7, fastener 8, clamp nut 9
The specific embodiment
Show among the figure that this formwork reinforcement bolt comprises the outer fastening fastener 8 of template and clamp nut 9, two external screw rods 1, two conehead nuts 3, an inner screw 5.Inner screw and two conehead nuts are in overlay film composite board 6 inboards of wall form, and the two ends of inner screw 5 connect minor diameter one end of two conehead nuts 3 respectively.External screw rod 1 passes wall form and is connected with a large diameter end of conehead nut.Fastener 8, clamp nut 9 are connected with the other end of external screw rod 1 in the outside of wall form.
In construction, withstand on overlay film composite board 6 inwalls of wall form by the larger diameter end of conehead nut 3, the length of inner screw 5 and conehead nut 3 is the cast width between the relative template.Regulate the length that screws of inner screw 5 and conehead nut 3, promptly can regulate the distance between two side templates, accurately control the dimensioning that waters of body of wall.External screw rod 1 is screwed by fastener 8 and clamp nut 9 with after conehead nut 3 is connected, and two side templates can be strained.Like this, outer bolt 1, conehead nut 3, inner bolt 5 have just played the double action of stretching screw and backform rod in the prior art.
Adopt the advantage of this template reinforcing bolt to be:
1. regulating tapered cup nut can very effective control wall section size;
2. speed of application can be accelerated because top die roller need not be installed, a large amount of reinforcing bar materials can be saved;
3. although the inner bolt in the body of wall can not be reused, the outer outer bolt of body of wall can be from tapered cup nut behind form removal In back-out and reuse, saved material;
4. tapered cup nut available screwdriver after form removable is back-outed from body of wall, recycling.
Claims (2)
