Description

Technical Field

[0001] The utility model belongs to the technical field of building structure auxiliary equipment, and particularly relates to a positioning tool for pre-buried pipes in walls. Background Art

[0002] Before pouring the wall, a through hole is opened at the corresponding position of the wall formwork to allow the embedded pipe to pass through the wall formwork, and then the embedded pipe is fixed to the wall steel bar, thereby completing the positioning of the embedded pipe on the wall. After pouring, a through hole defined by the embedded pipe is formed on the wall.

[0003] However, when pouring concrete, the embedded pipes are prone to falling or shifting due to the large impact force of the concrete, requiring secondary drilling using a water drill later, which increases the construction time. Utility Model Content

[0004] To solve the problems raised in the above background technology, the utility model provides a positioning tool for pre-buried pipes in walls, comprising a support fixed on a prefabricated wall panel and a triangular protective tube for inserting the pre-buried pipes, wherein a buffer assembly is provided on the support, and a triangular protective tube is provided on the buffer assembly.

[0006] As a positioning tool for wall embedded pipes of the utility model, preferably, a left limiting slider and a right limiting slider are respectively provided at the left and right ends of the limiting slide groove, and a left lower rotating shaft seat and a right lower rotating shaft seat are respectively provided on the left limiting slider and the right limiting slider.

[0007] As a positioning tool for wall embedded pipes of the utility model, preferably, the left limit slider and the right limit slider are matched with the limit slide groove, and the left limit slider and the right limit slider both slide left and right inside the limit slide groove.

[0008] As a positioning tool for wall embedded pipes of the utility model, preferably, the left limit slider and the right limit slider are both provided with sliding holes, and the left limit slider and the right limit slider are sleeved on the sliding rod through the sliding holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The support of the buffer component is installed on the prefabricated wall panel, and then the embedded pipe is inserted into the triangular protective tube. When pouring concrete, the falling concrete is first diverted by the protective tube with a triangular structure, reducing the area on the triangular protective tube under the action of concrete, thereby reducing the impact force of concrete discharge. The downward pressure of the concrete discharge on the triangular protective tube pushes the scissor arm composed of the left support rod and the right support rod downward through the mounting seat to change the angle, thereby pushing the left limit slider and the right limit slider to slide outward at the same time in the limit slide groove and compress the outer spring. At the same time, the reaction force of the outer spring is offset by the inner spring, so that the triangular protective tube is reset and the buffer component is used to reduce the direct impact of the concrete and prevent the embedded pipe from being damaged.
