Description
Technical Field
The utility model belongs to the field of concrete construction, and particularly relates to a tool for pulling out a concrete reserved sleeve.
Background
In the construction of the concrete structure, the reserved sleeve is required to be pulled out after the concrete pouring is finished, and workers at present directly pull out the reserved sleeve through tools such as pliers, but because the force application point of the pliers is only on the side wall of the reserved sleeve on one side, the reserved sleeve is difficult to pull out, or the reserved sleeve can be pulled out only with great effort; sometimes, workers use steel drills to directly break the reserved sleeve, use U-shaped steel drills to chisel out a bit, or directly use impact drills to drill holes and then use chisels to remove the reserved sleeve, but the method is slow and easy to damage surrounding concrete structures, and the chiseled reserved sleeve cannot be reused.
At present, some new tools for pulling out the reserved sleeve, such as patent publication number CN211313382U, use the lever principle to pull out the lower shaft rod in the reserved sleeve, similarly, patent publication number CN216196623U also uses the lever principle to pull out the reserved sleeve by using hooks, but the arc motion of the reserved sleeve increases the difficulty of pulling out the reserved hole of the vertical concrete due to the arc motion of the whole body in the pulling-out process of the method, and meanwhile, the two parts need to damage the upper part of the reserved sleeve to a certain extent, so that the reserved sleeve is reused later.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention.
The instrument is pulled out to 8 sleeves of concrete reservation of this embodiment includes L type dead lever 1, L type dead lever 1 includes horizontal pole 2 and montant 3, and horizontal pole 2 is longer, and montant 3 is shorter, and horizontal pole 2 is the rectangle pole, and montant 3 lower part becomes thinner gradually, and montant 3's medial surface is vertical face. In this embodiment, the L-shaped pulling rod 1 is made of iron material. The clamping plate 4 and the rubber block 6 are sequentially sleeved on the cross rod 2 of the L-shaped pulling rod 1, a rectangular hole A5 is formed in the upper portion of the clamping plate 4, a rectangular hole B7 is formed in the rubber block 6, the clamping plate 4 is sleeved on the cross rod 2 through the rectangular hole A5, the rubber block 6 is sleeved on the cross rod 2 through the rectangular hole B7, and the rubber block 6 is located outside the clamping plate 4. The clamping plate 4 is also made of an iron material, and the iron material is high in hardness, so that the later-stage hammer beating is facilitated. The vertical rod 3 and the clamping plate 4 of the L-shaped pulling rod 1 are used for extruding and clamping the reserved sleeve 8, and the rubber block 6 is used for preventing the clamping plate 4 from retreating and buffering the force born by a human hand. In order to further protect the reserved sleeve 8 and increase friction, rubber sheets are preferably arranged on the inner side surface of the vertical rod 3 of the L-shaped pulling rod 1 and the inner side surface of the vertical plate of the clamping plate 4, wherein the inner side surface is the surface contacted with the reserved sleeve 8.
The upper portion of above-mentioned splint 4 is the hang plate, and the contained angle of hang plate and vertical direction is about 3 ~ 10, and the lower part of splint 4 is the vertical board, and vertical board is parallel with montant 3, is equipped with the arc of outwards evagination between vertical board and hang plate, all slick and sly transitional coupling between arc and vertical board and the hang plate. When the arc-shaped plate is used for extruding the reserved sleeve 8 by the clamping plate 4, the upper end of the reserved sleeve 8 is prevented from being damaged by the upper part of the clamping plate 4, after the arc-shaped plate is arranged, the clamping plate 4 can not directly extrude the edge of the pipe wall at the upper end of the reserved sleeve 8, and the upper end of the reserved sleeve 8 is prevented from being damaged.
When the invention is used, the clamping plate 4 and the rubber block 6 are sleeved on the cross rod 2 in sequence, then the tool is placed above the reserved sleeve 8, the upper part of the reserved sleeve 8 is enabled to be positioned between the vertical rod 3 and the vertical plate at the lower part of the clamping plate 4, then the clamping plate 4 is knocked towards the direction of the reserved sleeve 8 by using the hammer, when the inclined plate is not perpendicular to the cross rod 2, a larger friction force exists between the inclined plate and the cross rod 2, the clamping plate 4 is not easy to slide on the cross rod 2, at the moment, the movable clamping plate 4 is knocked by the hammer, the reserved sleeve 8 is gradually clamped between the clamping plate 4 and the vertical rod 3 along with the movement of the clamping plate 4 to the reserved sleeve 8, the clamping plate 4 is continuously knocked by the hammer until the reserved sleeve 8 is slightly deformed, at the moment, the rubber block 6 is squeezed tightly by sliding the clamping plate 4, then the cross rod 2 between the vertical rod 3 and the clamping plate 4 is held by one hand, the rubber block 6 is pushed by the hand, then the reserved sleeve 8 is directly pulled upwards, the reserved sleeve 8 is pulled out, the upper part of the reserved sleeve 8 is slightly deformed, the reserved sleeve 8 is separated from the reserved sleeve 8, and the reserved sleeve 8 is pulled out in a vertical direction, and the reserved sleeve 8 can be pulled out in a repeated period.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; those of ordinary skill in the art will appreciate that: the technical scheme described in the above embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
