Abstract

The utility model relates to a vibrating spear positioning device. A bushing is suited on the excircle at the hose at the tail end of the vibrating spear, and a positioning sleeve is suited outside the bushing; a fixing clip is arranged on the excircle at the tail end of the hose of the positioning sleeve, the outer end of the vibrating spear is horn mouth shaped, and the distance from the external edge of the horn mouth to the excircle of the vibrating spear is 5 to 10 cm; one or more rows of U-shaped, V-shaped or L-shaped convex hangers are arranged on the outer wall of the bushing, and cylindrical, triangular or square hanging clips are correspondingly arranged on the inner wall of the positioning sleeve; the positioning sleeve and the bushing are made of rubber, and a swallowtail typebutting port is arranged on the side of the bushing. The vibrating spear positioning device has the following advantages: firstly, the structure is simple, the manufacture is easy, and the disassemblyand the assembly are convenient; secondly, the positioning device is made of rubber which is light and durable; thirdly, the effect of controlling the position of the insert type vibrating spear is good, and the concrete vibrating quality can be improved; fourthly, the operation is simple, the labor can be saved, and the practicability is strong.

Description

The vibrating head positioner

Technical field

The utility model relates to concrete construction field, is specifically related to the vibrating head positioner that vibrated concrete is used.

Background technology

In concrete placing, when adopting poker vibrator vibrated concrete works, by the job specfication requirement, vibrating head and side form should keep the distance of 5～10cm; Inserting lower-layer concrete also will have 5～10cm, to guarantee between two layer concretes in conjunction with good.When especially vibrating the base plate of large-sized prestress concrete box girder, because soffit formwork can not be installed attached vibrator, must vibrate by poker vibrator than the case beam base plate of book, vibrating head and soffit formwork also will maintain the distance of 5cm.Want to control well in construction these distances, relying on range estimation is because of difficulty, particularly when operator's fatigue, more restive.If taking to paint on vibrating head does sign, often be unable to undergo several frictions down in concrete vibrating, sign has not just had shadow, does not have ideal control effect equally.

Summary of the invention

The purpose of this utility model provides the vibrating head positioner of a kind of simple in structure, easy to use, easy operating, accurate positioning.

The technical solution of the utility model is for this reason: the vibrating head positioner, and the involving vibrations rod is characterized in that: be to be with lining on the tail end flexible pipe place of described vibrating head cylindrical, lining is with abutment sleeve outward; Abutment sleeve is provided with fixing card on flexible pipe tail end place cylindrical, be bell mouth shape in the outer end of vibrating head, and bell-mouthed outer edge is 5～10cm apart from the size of vibrating head cylindrical.

Improvement to such scheme is: be provided with a row or multi-row projection hook on the outer wall of described lining, correspondence is provided with projection and buckles on the inwall of abutment sleeve.

Further improvement of these options is: the hook on the described lining outer wall is U-shaped, the V-arrangement or L shaped of projection, and corresponding buckling is the columniform, leg-of-mutton or square of projection on the inwall of abutment sleeve.

Further improving again of such scheme is: described abutment sleeve and lining are made with rubber, and the lining side is provided with dovetail formula docking port.

Beneficial effect:

The utility model is provided with lining in the outside, tail end flexible pipe place of vibrating head, and lining is provided with abutment sleeve outward, and wherein the abutment sleeve lower end is bell mouth shape, and horn mouth edge is of a size of 5～10cm apart from the vibrating head barred body.Lining is can also be convenient to the abutment sleeve flexible positioning simultaneously by scratch for the tail end flexible pipe of protecting vibrating head; Behind the positioning sleeve chucking fixed bit, also can make things convenient for abutment sleeve and lining and flexible pipe to use pliable and toughly; It is the distance that can control vibrating head and side template maintenance 5～10cm that the abutment sleeve lower end is bell mouth shape one; The 2nd, can conveniently handle the excess stocks such as concrete that spattered up on the abutment sleeve; The 3rd, the sinking of transfiniting of controlling vibrating head can be arranged.

The outer wall of lining is provided with a row or multi-row U-shaped, V-arrangement or L shaped projection hook, the inwall of corresponding abutment sleeve is provided with buckling of projection, after abutment sleeve was inserted in lining, according to the barred body required size, the hook positioning of rotating sleeve of aiming at the relevant position just can buckle to embed to be linked up with.And then utilize the fixedly card of abutment sleeve upper end, and abutment sleeve is fixed on the lining easily, have that abutment sleeve makes progress when preventing that vibrating head from vibrating.

Described lining and abutment sleeve adopt rubber to make, mainly be that light durable, not yielding, easy accessibility, control position are effective, simple to operate, can save labor, effectively improve the concrete vibration quality, and utilize the elasticity and the flexibility of rubber, strengthen parcel power and the outer lining section of abutment sleeve can freely be bent with flexible pipe.Dovetail is adopted in the lining butt joint, can make its parcel vibrating bar hose tightr, also can keep the lining consistency of thickness, and the embedding that buckles of abutment sleeve is convenient in surfacing more.The utility model one be simple in structure, be easy to make easy accessibility; The 2nd, adopt rubber to make, light durable; The 3rd, effective to plug-type vibrating head control position, can improve the concrete vibration quality; The 4th, simple to operate, can save labor, practical.

The specific embodiment

As shown in Figure 1 and Figure 2, number in the figure: the 1st, vibrating head, the 2nd, abutment sleeve, the 3rd, sleeve buckle, the 4th, rubber bushing, the 5th, the hook on the lining, the 6th, vibrating bar hose, the 7th, dovetail tenon, the 8th, dovetail mouth, the 9th, fixing card, the 10th, buckle.

At first, determine the thickness of rubber bushing 4, guarantee that the hook 5 of its protrusion can stretch out the surface of vibrating head 1, so that buckling in the abutment sleeve 23 embeds according to the model of plug-in type vibrating head 1; The girth outline of rubber bushing 4 during parcel vibrating bar hose 6, is firmly squeezed the two ends of moving rubber bushing 4 less than the girth of vibrating bar hose 6 outer walls, and dovetail tenon 7 is embedded dovetail mouth 8.After rubber bushing 4 parcels are good, the abutment sleeve 2 of bell mouth shape is inserted in vibrating head 1, and make the sleeve on it buckle 3 facing to the space propultion in the hooks 5 on the rubber bushing 4, then according to required size, the rotational positioning sleeve 2 again, the corresponding line of 3 screw-in hooks 5 will be buckled, embed again in the groove of hook 5, behind the fix in position with the fixing card 9 of buckle 10 fastenings, can prevent that like this abutment sleeve 2 is stressed after, sleeve 2 upper ends buckle 3 skid off the hook 5, reach comparatively ideal locating effect.
