Abstract
The utility model relates to a pulling component for buildings, in particular to the pulling component which is used to construct concrete wall and column templates and mainly comprises a pulling component body which is provided with a steel bar through hole inside, a fastener and a retaining member which are installed on the pulling component body through a pulling screw cap. The pulling component is characterized in that the upper end of the fastener is provided with a threaded hole which is matched with the lower end of the pulling component body, a wedge shaped hollow cavity which is communicated with the threaded hole is arranged in the fastener, a wedge nail is installed on the inner wedge surface of the fastener, the wedge nail is connected and fixed with the fastener through a locking pin, and the fastener is fixed on the lower end of the pulling component body through the threaded hole on the upper end. The pulling component is characterized in that the manufacture is simple, the use is convenient, the fixation is reliable, the degree of tightness is suitable and the like, the disassembly and assembly are convenient, and the working efficiency is high.
Description
One, technical field
The utility model relates to a kind of top for building draw piece, and is especially a kind of to concrete wall and the working top of column template draw piece.
Two, background technology
In building trade, especially in the formwork construction of the post of frame construction and shear wall, all be unable to do without the top draw piece of fixed form, existing top draw piece mainly is that to cut screw with reinforcement rod through walls two ends be critical piece, in use be subjected to the quality influence of reinforcing bar self quality of materials and screw that cut at two ends, running and template drum mould phenomenon appears easily, fixed property is poor, degree of tightness is difficult to hold, very easily cause concrete casting quality not reach standard-required, and exist the number of turnover of reinforcement rod few, stock utilization is low, drawbacks such as operating efficiency difference.
Three, summary of the invention
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of easy to operate, fixed, the construction formwork top pull bar that can increase work efficiency is provided.
For achieving the above object, the utility model is achieved in that a kind of construction formwork top draw piece, establish in comprising reinforcement rod perforation top draw piece body, draw nut to be loaded on the securing member and the locking member on draw piece body top, top by the top, its special character is, be provided with the silk hole that matches with draw piece body lower end, top in the upper end of locking member, be provided with the wedge shape cavity that is connected with the silk hole in the locking member, interior wedge surface at locking member is equipped with the wedge nail, the wedge nail is connected and fixed by pinning and locking member, and locking member spins by the silk hole on it and is fixed in the lower end of top draw piece body.
The good effect that compared with the prior art the utility model has is, and is rational in infrastructure, easy to use, is easy to dismounting, fixed, and degree of tightness degree of having uses the number of turnover many, and the stock utilization height can be increased work efficiency greatly.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
Fig. 3 is user mode figure of the present utility model.
Five, the specific embodiment
With reference to Fig. 1, Fig. 2 as seen, construction formwork described in the utility model top draw piece, mainly be to constitute by interior top draw piece body 1, securing member 5 and the locking member 2 of establishing the reinforcement rod perforation, securing member 5 draws nut 4 to be installed on the top draw piece body 1 by the top, be provided with the silk hole that the lower end with top draw piece body 1 matches in the upper end of locking member 2, be provided with the wedge shape cavity that is connected with the silk hole in the locking member 2, interior wedge surface at locking member is equipped with wedge nail 3, wedge nail 3 is fixedlyed connected with locking member 2 by pinning 7, and locking member 2 spins by the silk hole on it and is fixed in the lower end of top draw piece body 1.
During use as shown in Figure 3, after now reinforcing bar 6 being run through template 9, respectively penetrate in the reinforced steel bar perforation of above-mentioned top draw piece at the two ends of reinforcing bar 6, then wedge nail 3 is headed into the interior wedge surface of locking member 2 and loads onto lock top 7, top power is big more, reinforcing bar 6 is just held tight more, draw nut 4 with spanner clockwise direction twisting top again after the degree of tightness appropriateness, thereby it is fixing with clamping steel pipe 8 and template 9 to promote securing member 5, after the concreting in the template 9 finishes, counterclockwise twist the top with spanner again and draw nut 4, make securing member 5 loosening, leave clamping steel pipe 8, unload lower bolster top draw piece and get final product, easy to use flexible, the efficient height.
