Technical Field

The utility model belongs to the technical field of the key assembled construction who promotes of country, concretely relates to vertical grout sleeve of assembled concrete that has the quick shutoff structure of slip casting mouth.

Background

The grouting fullness and compactness of the vertical grouting sleeve for the reinforcement connection of the prefabricated concrete structure directly influence the grouting quality, the connection quality of the prefabricated concrete structure and the structural safety.

I department is doing the research and development of this direction always, in utility model patent CN201821485099.9 "a prefabricated concrete structure vertical component installation grout caulking structure", put emphasis on prefabricated concrete structure steel bar connection and joint grout caulking and handle, in utility model patent CN201921341900.7 "a prefabricated concrete half grout sleeve", through the round platform shape cock of steam extraction downthehole installation, and open in the middle of the cock and have 2 mm's steam extraction hole, the cock periphery is opened has four 3 mm's semicircle orifices, through steam extraction hole steam extraction, drainage, row thin slurry, arrange thick liquid, the cock moves to the appearance of five phenomenons such as outer mouthful tie, can inspect in the construction and prove that the slip casting is full and closely knit.

However, the above measures still lack an important link in construction, that is, after grouting is completed, the grouting mouth needs to be plugged by a wooden plug, but the grouting slurry has high fluidity, the initial fluidity is 300mm, and the initial fluidity is 260mm in 30min, so that the plugging of the grouting mouth is slow, the outflow of the injected slurry is large, the grouting fullness and compactness of the sleeve are poor, and the connection quality of the steel bar grouting sleeve is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vertical grout sleeve of assembled concrete with quick shutoff structure of slip casting mouth to solve grout slurry mobility very big, when the shutoff of slip casting mouth is slow slightly, the slurry of notes advance can flow more, leads to plumpness, closely knit degree not good enough behind the sleeve slip casting, has the cavity, influences reinforcing bar grout muffjoint quality.

In order to solve the above problems, the utility model discloses technical scheme does:

the assembled concrete vertical grouting sleeve with the rapid grouting port plugging structure comprises a sleeve body, a steam exhaust hole and a grouting port, wherein the steam exhaust hole is formed in the upper part of the sleeve body, and the grouting port is formed in the lower part of the sleeve body; the grouting opening is provided with a plugging plugboard gap close to the opening, and the plugging plugboard gap is movably provided with a plugging plugboard matched with the plugging plugboard gap.

Furthermore, the plugging plugboard is hinged to the opening close to the grouting opening through a rotating shaft, and the plugging plugboard can be inserted into the gap of the plugging plugboard in a rotating mode along the rotating shaft.

Furthermore, the grouting opening is movably arranged at the lower part of the sleeve body through a screw thread.

Furthermore, the sleeve body is connected with the steam exhaust hole in a threaded connection mode.

Furthermore, a plastic cap or an adhesive tape is movably arranged on the steam exhaust hole and the grouting opening.

The utility model has the advantages as follows:

the utility model discloses through the quick shutoff structure of slip casting mouth that has repeatedly tested and developed with sleeve body structure looks adaptation, through the institutional advancement to the slip casting mouth, utilize the shutoff picture peg gap and the shutoff picture peg of establishing of joining in marriage the cover, the back is accomplished in the slip casting, and the shutoff just can be accomplished in 1-2 seconds to slewing shutoff picture peg to shutoff picture peg gap department, and does not leak thick liquid behind the shutoff, guarantees the plumpness and the closely knit degree of slip casting. Improve the grout effect, guarantee the quality of assembled concrete reinforcement sleeve grout connection. Has very high practicality in the actual production, can promote slip casting quality greatly.

The sleeve is made of steel pipe cutting and casting; the sleeve made of cast materials is processed due to the limited environmental protection, the sleeve processed by cutting the steel pipe cannot be connected together for manufacturing, the materials are embrittled and the plasticity is poor due to welding, so the sleeve body and the grouting opening are connected by a screw connection mode, and the sleeve body and the steam exhaust hole are connected by the screw connection mode on the same principle.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are 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 work belong to the protection scope of the present invention.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

Examples

As shown in fig. 1-2, the assembled concrete vertical grouting sleeve with a rapid grouting port plugging structure comprises a sleeve body 1, a steam exhaust hole 2 and a grouting port 3, wherein the steam exhaust hole 2 is arranged at the upper part of the sleeve body 1, and the grouting port 3 is arranged at the lower part of the sleeve body 1; a plugging inserting plate gap 32 is arranged at the position, close to the opening, of the grouting opening 3, and a plugging inserting plate 33 matched with the plugging inserting plate gap 32 is movably arranged at the plugging inserting plate gap 32.

Specifically, the method comprises the following steps: the plugging inserting plate 33 is hinged to the opening part of the grouting opening 3 through a rotating shaft 34, and the plugging inserting plate 33 can be rotatably inserted into the plugging inserting plate gap 32 along the rotating shaft 34.

The grouting opening 3 is movably arranged at the lower part of the sleeve body 1 through a screw thread 31.

The sleeve body 1 and the steam exhaust hole 2 are connected by a thread connection mode.

A plastic cap or an adhesive tape is movably arranged on the steam exhaust hole 2 and the grouting opening 3. This setting is in order to prevent that grout from getting into the sleeve when precast concrete component, influencing the installation engineering quality. Before the component is installed and grouted, the plastic cap or the adhesive tape is removed.

When the precast member concrete is poured, the grouting opening needs to be 3mm higher than the surface of the member concrete, otherwise, the rotation of the inserting plate is influenced. The grout injection port, the steam exhaust hole and the lower port inserted into the lower anchor bar do not leak cement grout when concrete is poured. The upper opening is a straight thread connection part of the steel bar, and the steel bar is additionally connected to ensure that the slurry is not leaked.

During operation, grouting is carried out from the grouting opening 3, steam is exhausted from the steam exhaust hole 2, five phenomena of steam exhaust, water drainage, slurry discharge, thick slurry discharge, plug movement to the outside and the like are met to indicate full filling, after the full filling, the plugging inserting plate 33 is rapidly rotated to be inserted into the plugging inserting plate gap 32, plugging can be completed within 1-2 seconds, and no slurry leakage exists after plugging.
