Description
Technical Field
The utility model relates to an exhaust formula grout sleeve technical field especially relates to an exhaust formula grout sleeve.
Background
The existing grouting sleeve is manufactured by adopting a casting process or a machining process, the sleeve grouting material for steel bar connection is prepared by taking cement as a basic material and matching with dry mixed material which is formed by mixing fine aggregate, admixture and other materials and is used for steel bar sleeve grouting connection, but the outer wall of the existing grouting sleeve is frosted, but the roughness of the surface of the existing grouting sleeve is insufficient, so that the integrity between the grouting sleeve and a steel bar is poor, the gripping force is small, in addition, an annular groove is formed in the inner wall of the grouting sleeve, when sleeve grouting is carried out, air in the sleeve is not easy to discharge, bubbles or gaps are easy to appear in the grouting material, and the connection between the grouting sleeve and the steel bar is unstable.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a exhaust formula grout sleeve that the wholeness is good, the bond stress is big, pass power effectual, and easy carminative is provided.
In order to solve the technical problem, the utility model provides a pair of exhaust formula grout sleeve, it includes the barrel, be equipped with grout mouth and grout outlet on the barrel, the inner wall of barrel is followed the length direction interval of barrel is equipped with a plurality of annular grooves uniformly, the inner wall of barrel is equipped with vertical recess, just vertical recess runs through all annular groove, be equipped with the spring muscle on the vertical recess.
As the utility model discloses preferred scheme, the outer wall of barrel is followed the length direction of barrel has evenly arranged the protruding group of multiunit, protruding group includes a plurality of edges the arch that the circumferencial direction of barrel evenly arranged.
As the preferred scheme of the utility model, the arch is circular-arc outwards protruding.
As the preferred scheme of the utility model, the upper portion of barrel is the back taper.
As the utility model discloses preferred scheme, vertical recess is followed the circumferencial direction of barrel is evenly arranged with at least two.
As the utility model discloses preferred scheme, the spring muscle is zigzag spring muscle, the sawtooth of spring muscle is higher than the notch of vertical recess.
As the utility model discloses preferred scheme, the grout outlet sets up the upper portion of barrel, the grout mouth sets up the lower part of barrel.
Implement the utility model discloses an exhaust formula grout sleeve compares with prior art, has following beneficial effect:
the utility model organically combines the annular grooves and the vertical grooves penetrating through all the annular grooves, so that when sleeve grouting is carried out, air in the sleeve can be discharged through the vertical grooves, the generation of bubbles or gaps between the exhaust type grouting sleeve and grouting material is reduced, the connection between the reinforcing steel bars and the reinforcing steel bars is more stable, the integrity of the reinforcing steel bars and the reinforcing steel bars is improved, and the air is easy to exhaust; in addition, be equipped with the spring muscle in vertical recess, make spring muscle and reinforcing bar have the contact, increase the bond stress with the reinforcing bar, it is better to pass the power effect.
Drawings
In order to more clearly illustrate the technical solution of the embodiments of the present invention, the drawings of the embodiments will be briefly described below.
Fig. 1 is a front view of an air discharge type grout sleeve provided in the present invention;
fig. 2 is a top view of an exhaust type grouting sleeve provided in the present invention;
fig. 3 is a sectional view of an exhaust type grouting sleeve provided by the present invention;
the labels in the figure are: 1 is the grout mouth, 2 is the grout outlet, 3 is annular groove, 4 is vertical recess, 5 is the spring muscle, 6 is protruding group, 7 is the arch, 8 is the barrel.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-3, the utility model discloses a preferred embodiment, an exhaust formula grout sleeve, including barrel 8, be equipped with grout mouth 1 and grout outlet 2 on the barrel 8, grout outlet 2 sets up the upper portion of barrel 8, grout mouth 1 sets up the lower part of barrel 8, the inner wall of barrel 8 is followed the length direction interval of barrel 8 is equipped with a plurality of annular groove 3 uniformly, the inner wall of barrel 8 is equipped with vertical recess 4, just vertical recess 4 runs through all annular groove 3, be equipped with spring muscle 5 on the vertical recess 4.
Therefore, through the organic combination of the annular grooves 3 and the vertical grooves 4 penetrating through all the annular grooves 3, when sleeve grouting is carried out, air in the sleeve can be discharged through the vertical grooves 4, the generation of air bubbles or gaps between the grouting sleeve and grouting material is reduced, the connection between the reinforcing steel bars is more stable, the integrity of the reinforcing steel bars is improved, and the air is easy to exhaust; in addition, be equipped with spring muscle 5 in vertical recess 4, make spring muscle 5 and reinforcing bar have the contact, increase the bond stress with the reinforcing bar, it is better to pass the power effect.
Exemplarily, the outer wall of barrel 8 has evenly arranged the protruding group 6 of multiunit along the length direction of barrel 8, protruding group 6 includes a plurality of edges the arch 7 of the even arrangement of the circumferencial direction of barrel 8, arch 7 is circular-arc outside protruding, makes the grout material can better cladding in the outside of arch 7, reduces the production of cavity between exhaust formula grout sleeve and the grout material, increases the connection steadiness, wholeness and the bond strength between exhaust formula grout sleeve and the assembled concrete component.
Illustratively, the upper portion of barrel 8 is the back taper, avoids causing rigidity sudden change phenomenon because upper portion reinforcing bar mechanical connection rigidity is big, saves material, and is with low costs.
Exemplarily, vertical recess 4 is followed the circumferencial direction of barrel 8 is evenly arranged with at least two, in this embodiment, vertical recess 4 is equipped with threely, utilizes triangle-shaped stability principle, and the point connection of spring muscle 5 in the three vertical recess 4 and reinforcing bar contact increases the stability of reinforcing bar, and is concrete, spring muscle 5 is preferred zigzag spring muscle 5, the sawtooth of spring muscle 5 is higher than the notch of vertical recess 4, improves the air exhaust formula grout sleeve and the connected steadiness of reinforcing bar, guarantees to pass power effect.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
