Technical Field
[0001] The utility model relates to the technical field of construction, in particular to an anti-falling grouting device used for grouting of prefabricated concrete components. Background Art
[0002] In the prior art, when grouting concrete precast components, the traditional technology uses plastic grouting pipes and pipe plugs without anti-dropping structures. After grouting is completed, the pipe plug is installed into the internal thread of the grouting pipe. Since there is no anti-loosening structure between the pipe plug and the grouting pipe, the pipe plug is easy to loosen and fall off during long-term use due to factors such as vibration.
[0003] The industry needs a product that can prevent loosening to solve the above problems. Utility Model Content
[0004] In order to solve the above problems, the utility model discloses an anti-falling grouting device for grouting of prefabricated concrete components.
[0005] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:
[0006] An anti-falling grouting device for grouting of prefabricated concrete components, comprising:
[0007] Grouting pipe, used for pre-embedding in precast concrete components;
[0008] A pipe plug, used to seal the grouting pipe after grouting is completed;
[0009] The mouth of the grouting pipe is provided with a rotation-stopping buckle tooth, and the end of the pipe plug is provided with an outwardly projecting elastic fastener matched with the rotation-stopping buckle tooth.
[0010] As a further improvement of the utility model, the anti-rotation buckle teeth are arranged on the inner side of the circular ring of the grouting pipe mouth, and each of the anti-rotation buckle teeth includes an anti-rotation slope surface and an anti-rotation abutment section.
[0011] As a further improvement of the present invention, the anti-rotation buckle teeth are distributed in a circular ring shape on the inner side of the grouting pipe mouth.
[0012] As a further improvement of the present invention, the outwardly projecting elastic fastener is elastically connected to the end of the pipe plug, and the outwardly projecting elastic fastener includes a spring-loaded anti-rotation inclined surface adapted to the anti-rotation slope surface and a spring-loaded anti-rotation section adapted to the anti-rotation abutment section.
[0013] As a further improvement of the present invention, the outwardly projecting elastic fastener and the pipe plug are integrally formed.
[0014] As a further improvement of the utility model, the anti-rotation slope surface faces the end surface of the grouting pipe or the axis of the grouting pipe, and the spring-lock anti-rotation slope surface is adapted to the anti-rotation slope surface.
[0015] As a further improvement of the utility model, when the anti-rotation slope surface faces the end surface of the grouting pipe, the spring buckle anti-rotation slope surface faces the front end surface of the pipe plug;
[0016] The outwardly projecting elastic fastener can be elastically deformed toward the front end surface or the rear end surface of the pipe plug.
[0017] As a further improvement of the utility model, when the anti-rotation slope surface faces the axis of the grouting pipe, the spring buckle anti-rotation slope surface faces the radial outer periphery of the pipe plug;
[0018] The outwardly protruding elastic fastener can be elastically deformed toward the radial inner side or the radial outer side of the pipe plug.
[0019] The cooperation between the anti-rotation slope surface of the anti-rotation buckle tooth at the grouting pipe mouth and the spring-lock anti-rotation slope surface of the elastic fastener protruding from the pipe plug can enable the elastic fastener protruding from the pipe plug to pass over the anti-rotation buckle tooth at the grouting pipe mouth through elastic deformation when the pipe plug is screwed into the internal thread of the grouting pipe; and when the pipe plug rotates in the opposite direction, the anti-rotation section of the elastic fastener protruding from the pipe plug presses against the anti-rotation contact section of the anti-rotation buckle tooth at the grouting pipe mouth to prevent the pipe plug from continuing to rotate in the opposite direction and avoid the pipe plug from falling off.
[0020] When the pipe plug needs to be removed, a tool is used to buckle the outwardly extending elastic fastener so that the anti-rotation section of the outwardly extending elastic fastener leaves the anti-rotation abutment section of the anti-rotation buckle tooth of the grouting pipe mouth, and then the pipe plug is reversed to remove the pipe plug.
[0021] The anti-rotation slope surface of the anti-rotation buckle teeth at the mouth of the grouting pipe can point to the end of the grouting pipe, that is, toward the end surface of the grouting pipe; it can also point to the axis of the grouting pipe, that is, the anti-rotation slope surface faces the axis of the grouting pipe. When the anti-rotation slope surface of the anti-rotation buckle teeth at the mouth of the grouting pipe can point to the end of the grouting pipe, the spring-buckle anti-rotation slope surface of the elastic fastener protruding from the pipe plug points to the outer end of the pipe plug, that is, the spring-buckle anti-rotation slope surface faces the front end surface of the pipe plug; when the anti-rotation slope surface of the anti-rotation buckle teeth at the mouth of the grouting pipe points to the axis of the grouting pipe, the spring-buckle anti-rotation slope surface of the elastic fastener protruding from the pipe plug points to the radial outer periphery of the pipe plug.
[0022] The beneficial effects of the utility model are as follows: the utility model has a reasonable and ingenious structural design, and by arranging a rotation-stopping buckle tooth at the grouting pipe mouth and an outwardly extending elastic fastener on the pipe plug, the pipe plug can be well fixed on the grouting pipe to prevent the pipe plug from loosening and falling off.

[0035] See also Figures 1 to 10 The present embodiment provides an anti-drop grouting device for grouting of concrete prefabricated components, comprising a grouting pipe 1 and a pipe plug 2, wherein a rotation-stopping buckle tooth 3 is arranged inside the circular ring at the mouth of the grouting pipe 1, and each rotation-stopping buckle tooth 3 comprises a rotation-stopping slope surface 4 and a rotation-stopping abutment section 5;
[0036] The anti-rotation buckle teeth 3 arranged inside the circular ring at the mouth of the grouting pipe 1 are distributed along the circular ring;
[0037] The pipe plug 2 is provided with an outwardly extending elastic fastener 6, each of which comprises an elastic fastener anti-rotation inclined surface 7 and an elastic fastener anti-rotation section 8, and the arrangement position of the outwardly extending elastic fastener 6 corresponds to the anti-rotation fastener tooth 3;
[0038] The outwardly extending elastic fastener 6 is elastically connected to the end of the pipe plug 2. One end of the outwardly extending elastic fastener is fixed to the end of the pipe plug 2.
[0039] The outwardly extending elastic fastener 6 and the pipe plug 2 are integrally formed.
[0040] In other embodiments, the outwardly extending elastic fastener 6 and the pipe plug 2 may also be manufactured separately and then fixedly connected.
[0041] The anti-rotation slope surface 4 faces the end surface of the grouting pipe 1 or the axis of the grouting pipe 1 , and the spring-lock anti-rotation slope surface 7 is matched with the anti-rotation slope surface 4 .
[0042] When the anti-rotation slope surface 4 faces the end surface of the grouting pipe 1, the spring buckle anti-rotation slope surface 7 faces the front end surface of the pipe plug 2;
[0043] The outwardly projecting elastic fastener 6 can be elastically deformed toward the front end surface or the rear end surface of the pipe plug 2 .
[0044] When the anti-rotation slope surface 4 faces the axis of the grouting pipe 1, the spring-lock anti-rotation slope surface 7 faces the radial outer periphery of the pipe plug 2;
[0045] The outwardly protruding elastic fastener 6 can be elastically deformed toward the radial inner side or outer side of the pipe plug 2 .
[0046] Specifically, the anti-rotation slope surface 4 of the anti-rotation buckle tooth 3 at the mouth of the grouting pipe 1 and the spring-lock anti-rotation slope 7 of the elastic fastener 6 of the pipe plug 2 can cooperate to make the elastic fastener 6 of the pipe plug 1 pass over the anti-rotation buckle tooth 3 at the mouth of the grouting pipe 1 through elastic deformation during the process of the pipe plug 2 being screwed into the internal thread of the grouting pipe 1; and when the pipe plug 2 rotates in the reverse direction, the spring-lock anti-rotation section 8 of the elastic fastener 6 of the pipe plug 2 presses against the anti-rotation abutment section 5 of the anti-rotation buckle tooth 3 at the mouth of the grouting pipe 1 to prevent the pipe plug 2 from continuing to rotate in the reverse direction and avoid the pipe plug 2 from falling off;
[0047] When the pipe plug 2 needs to be removed, the outwardly extending elastic fastener 6 is buckled with a tool to make the spring buckle anti-rotation section 8 of the outwardly extending elastic fastener 6 leave the anti-rotation abutment section 5 of the anti-rotation buckle tooth 3 at the mouth of the grouting pipe 1, and then the pipe plug 2 is reversed to remove the pipe plug 2;
