Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a portable mortar spreading device. Background Art

[0002] At the construction site, it is necessary to build brick walls. The brick walls are built by layer upon layer of brick courses. When laying a brick course, it is necessary to carry out a mortar spreading process (usually spreading cement), and then place bricks in sequence, repeating this cycle. When spreading mortar, not only does it require adjusting the mortar to maintain a certain thickness during the mortar spreading process to make the mortar joints uniform and proper, but also according to the requirements of joint beautification, adjusting the inward contraction size of the mortar joints to carry out the process of brick wall jointing. The process is numerous, the procedures are complex, the time occupancy is large, the physical strength and proficiency requirements for workers are relatively high, and at the same time, it affects the project progress and makes the construction efficiency low, which needs to be improved.

The two connecting rods are located at both ends of the limiting rods in the length direction. The fixing component includes a fixing nut and a limiting nut. The limiting nut is located on one side where the two limiting rods face each other, and the fixing nut is located on the side where the two limiting rods face away from each other. The limiting nut is threadedly connected to the connecting rod, and the limiting nut abuts against the limiting rod to limit the two limiting rods from moving towards each other. The fixing nut is threadedly connected to the connecting rod, and the fixing nut abuts against the limiting rod to limit the two limiting rods from moving away from each other.
