Abstract
The utility model relates to a template reinforcing device in the concrete construction field, in particular to an adjustable template opposite pull rod, and solves the problems that the thread head of the prior template opposite pull rod is easily broken, can not be used repeatedly and has small adjustable amplitude. The adjustable template opposite pull rod comprises an inner screw rod and an outer screw rod as well as a sleeve pipe sleeved on the inner screw rod and the outer screw rod; limiting convex rings are arranged on the outer ends of the inner screw rod and the outer screw rod, and opposite pull holes are formed on the inner screw rod and the outer screw rod outside the limiting convex rings; and the two ends of the sleeve pipe are respectively attached to the limiting convex rings of the inner screw rod and the outer screw rod. The utility model adopts the inner screw rod and the outer screw rod which are in threaded connection as well as the sleeve pipe connected as the opposite pull rod, achieves the pulling and fixation of the template, shields the thread head of the pull rod, which is not easily broken and can be used repeatedly for a long time, randomly regulates the adaptation length of the inner screw rod and the outer screw rod according to the thickness of the section of concrete, meets the requirements of different occasions, has the advantages of skillful design, lower fabrication cost and good use effect, and can be widely applied to the reinforcement of the template in concrete construction.
Description
Technical field
The utility model relates to concrete construction field formwork reinforcement device, is specially a kind of adjustable formwork to pull bar.
Background technology
At present, when concrete construction, template is owing to be subjected to the effect of concrete lateral pressure to be easy to generate lateral shift.Be to guarantee physical dimension, the lateral deformation of restriction template is adopted in the construction now and draw piece is carried out drawknot to concrete two side templates is fixed.Common by form by screw rod and screw common to pull bar and the combined type that has a rubber cap to forms such as pull bars, owing to above-mentioned pull bar silk head is exposed, very easily the silk head is destroyed in the turnover use, thereby influence its repeated use, and the concrete section to the only suitable specific thicknesses of pull bar of said structure form, degree of amplitude modulation is little, or the spiro rod length deficiency, or exposes long destroyed easily.
Summary of the invention
The utility model for solve existing template to pull bar since structural defective exist the silk head easily destroyed, can't reuse and degree of amplitude modulation little and can only be used for the problem of the concrete section of specific thicknesses, provide a kind of adjustable formwork to pull bar.
The utility model is to adopt following technical scheme to realize: adjustable formwork is to pull bar, comprise the interior screw mandrel and the out screw rod of threaded engagement and be set in sleeve pipe on screw mandrel and the out screw rod, interior screw mandrel, out screw rod outer end are respectively equipped with position limiting convex ring, are positioned on the screw mandrel, out screw rod in the position limiting convex ring outside to have pulling eye; The sleeve pipe two ends are close to the position limiting convex ring of interior screw mandrel, out screw rod respectively.Materials such as described sleeve pipe employing plastics are made, and can determine its processing length according to actual needs, and disposal pouring does not have enough to meet the need in concrete.
The conduct that cooperatively interacts of interior screw mandrel, out screw rod and the sleeve pipe of the utility model employing screwed connection is to pull bar, the drawknot of realization template is fixed, hidden to the pull bar silk, survivable, can reuse for a long time, and can be according to the length of fit of screw mandrel, out screw rod in the thickness regulated at will of concrete section, degree of amplitude modulation is bigger, the needs that adapt to different occasions, the utility model design is ingenious, cost of manufacture is lower, but practical effect is better, can be widely used in the reinforcing of template in the concrete construction.

The specific embodiment
Adjustable formwork is to pull bar, shown in Fig. 1,3, comprise the interior screw mandrel 1 and the out screw rod 2 of threaded engagement and be set in sleeve pipe 3 on screw mandrel 1 and the out screw rod 2, interior screw mandrel 1, out screw rod 2 outer ends are respectively equipped with position limiting convex ring 4, are positioned on the screw mandrel 1, out screw rod 2 in position limiting convex ring 4 outsides to have pulling eye 5; Sleeve pipe 3 two ends are close to the position limiting convex ring 4 of interior screw mandrel 1, out screw rod 2 respectively.
As shown in Figure 2, when template 9 is installed, make sleeve pipe according to concrete section thickness in advance, make sleeve pipe two ends inwall and position limiting convex ring be close to and do not stay the slit, inside and outside screw mandrel that will assemble then and cover tube stay are in two side template inboards, position limiting convex ring abuts against the template medial surface, carries out the reinforcing of template outside back cord then.During reinforcing will by eave tile screw 6,3 shape cards 7 and steel pipe 8 will to the two ends of pull bar to pulling eye and back cord tension, thereby guaranteeing that template is inboard is adjacent to position limiting convex ring.
