Two-way sliding wall-building joint pointing device capable of being interchangeably used by left and right hands

Abstract

The invention relates to a two-way sliding wall-building joint pointing device capable of being interchangeably used by left and right hands. The two-way sliding wall-building joint pointing device ischaracterized in that a left holding rod and a right holding rod which are welded together in a crescent shape form a main body, and a threaded hole and a screw rod rotating in the threaded hole arearranged at a middle welding position; a left pulley and a right pulley which are symmetrical to the screw rod are arranged on the left holding rod and the right holding rod respectively; fixing shafts are arranged on the left holding rod and the right holding rod respectively and run through the left pulley and the right pulley; clamping buckles are arranged at positions, positioned at the two ends of the left pulley and the right pulley, of the fixing shafts; segmental arc fixing rods capable of rotating around the fixing shafts are arranged at the middle positions of the fixing shafts; thesegmental arc fixing rods are symmetrically distributed by using the screw rod as a center. Through the left holding rod and the right holding rod capable of being interchangeably used by left and right hands, after one hand works till a tired state, the other hand can work, so that the two-way sliding wall-building joint pointing device is convenient to use and easy to operate; in addition, through the middle screw rod, the smearing and pressing depths of joint beautifying boards on the two sides are adjusted, so that the two-way sliding wall-building joint pointing device is ingenious in design and convenient and fast to operate.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a two-way sliding wall pointing device which can be used interchangeably with left and right hands. Background technique [0002] Generally, in the process of clear water wall construction, cement mortar is used to bond bricks and bricks. The specification stipulates that the thickness of the horizontal and vertical mortar joints of the wall is 8-12mm; On the one hand, it is more beautiful, on the other hand, it increases the strength of the wall. [0003] At present, in the process of building a wall, the gap between two bricks is filled by the wall-builder with a tile knife or a mud trowel to fill the gap, and the mixture filled in the gap of the wall is first applied and accumulated on the gap , because there is a certain viscosity between the mixtures, the mortar will stick to the gaps. [0004] Next, the mixture will be pressed. Generally, in order to impr...

Problems solved by technology

[0004] Next, the mixture will be pressed. Generally, in order to improve the efficiency of building walls, workers usually use a trowel to insert mortar from both sides of the gap to improve the efficiency of the wall. It looks like the gap is full of mortar, but the middle is empty. ; This will also cause insecurity in the future use of the wall

[0005] Moreover, the strength of the mud trowel is not easy to control during use, which will cause the depth of gap filling to be inconsistent, so that the structure of the wall will be unstable after being attacked by wind and rain for a long time, and it is easy to cause safety hazards. Therefore, it is urgent to design a The wall pointing device can be used alternately by the left and right hands during the use of the workers to reduce the labor fatigue of the workers
