Description

Half grout sleeve

Technical Field

The utility model relates to the technical field of a grout anchor type sleeve connecting piece for connecting steel bars among precast concrete components, in particular to a semi-grouting sleeve.

Background

The steel bars poured in the concrete can act together with the solidified concrete to form a firm reinforced concrete structure, the reinforced concrete structure is widely applied to the field of civil engineering construction, the reinforced concrete needs to be prefabricated in many times in order to accelerate the construction progress and ensure the engineering quality, when the reinforced concrete structure is installed, the connection of the longitudinal steel bars among prefabricated components is a difficult problem, and the reliable transmission of force among the connected steel bars must be ensured.

The grouting sleeve for connection is proved by engineering practice for decades, and the connection method is simple and easy to operate and has good joint effect. At present, the semi-grouting sleeve is widely used in the fabricated building, and the using amount of the semi-grouting sleeve is large. Half grout sleeve prefabrication end is mostly screw thread prefabricated connection with the reinforcing bar, will twist half grout sleeve's prefabrication end with the reinforcing bar promptly and pour into the grout material in half grout sleeve, realizes the component connection through the mechanical interlock and the friction between grout material and reinforcing bar and half grout sleeve.

However, when one end of the existing half grouting sleeve is injected into a grouting hole, the problems of insufficient grouting and incompact are easily caused, the connection reliability is affected, and the tension and compression resistance is reduced. And the other end is connected through the screw thread sometimes because the problem of screw thread machining precision also can influence the reliability of connection, reduces the ability of resistance to tension and compression.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model aims to provide a semi-grouting sleeve which is simple in structure, greatly improves the grouting compactness and the tension and compression resistance, and is higher in connection reliability.

In order to solve the problems, the utility model adopts the following technical scheme: a semi-grouting sleeve comprises a sleeve body, and a grouting hole and a grout overflow hole which are communicated with an inner cavity of the sleeve body, and is characterized in that,

the sleeve body is of a hollow cavity structure, the left end of the sleeve body is a grouting insertion end, the right end of the sleeve body is a screw thread connecting end, a plurality of annular bulges are arranged on the inner wall of the inner cavity of the sleeve body and divided into a whole-ring annular bulge and a non-whole-ring annular bulge, the non-whole-ring annular bulge is provided with a communicating notch, the whole-ring annular bulge and the non-whole-ring annular bulge are alternately arranged, the top of the annular bulge is provided with a groove with an arc-shaped cross section,

the inner wall of the screw thread connecting end is provided with a connecting screw thread, the inner wall of the screw thread connecting end is provided with an annular reinforcing groove, the annular reinforcing groove is positioned at the left side of the connecting screw thread,

and an H-shaped reinforcing rib is arranged on the outer wall of the right end of the sleeve body.

The utility model has the beneficial effects that:

1. its simple structure has improved the compactness of slip casting and the ability of tensile pressure greatly, and the connection reliability is higher.

2. Annular bulge divide into the annular bulge of whole ring and the annular bulge of non-whole ring, and the annular bulge of non-whole ring is equipped with the intercommunication breach, and the annular bulge of whole ring sets up with the annular bulge of non-whole ring in turn, and what this kind of structural design was so that when carrying out the slip casting operation, each position of cavity was arrived in the flow that the grout can be abundant, had improved the degree of compactness of slip casting greatly to make after the grout solidifies more firm with being connected of reinforcing bar.

3. Annular protruding top be equipped with the cross section and be circular-arc recess for the grout material is stronger with the ability of anti fore-and-aft pulling force or pressure between the annular arch after solidifying, the annular protruding top of avoiding simultaneously appears the not compact phenomenon of slip casting, connects the reliability higher.

4. Be equipped with cyclic annular strengthening groove on the inner wall of screw thread link, cyclic annular strengthening groove is located the left side of connecting the screw thread, has avoided the screw thread link because the problem of the reliability of screw thread machining precision problem influence connection, and grout gets into cyclic annular strengthening groove and solidifies the back, can further fasten the reinforcing bar tip that the screw thread link is connected, has improved the tension and compression resistance ability of screw thread link greatly.

5. The outer wall of the right end of the sleeve body is provided with the H-shaped reinforcing ribs, the structural design improves the tensile and compression resistance of the right end of the sleeve body, and the connection reliability is higher.
