Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, especially a kind of masonry horizontal mortar joint thickness control tool. BACKGROUND

[0002] Mortar joint mostly refers to the mortar layer between two bricks when wall is built, i.e. the joint line when brick and brick are bonded with mortar and then troweled out. Mortar joint is divided into horizontal mortar joint and vertical mortar joint, and the mortar joint between upper and lower skins of block is called horizontal joint, and the joint between adjacent blocks is called vertical joint. It affects the strength, heat preservation, heat insulation, impermeability, frost resistance and other properties of masonry. In brick masonry, the thickness of mortar joint is generally 10mm, but should not be less than 6mm, and should not be greater than 15mm.

[0003] Indoor sub-house partition wall generally uses autoclaved aerated concrete block and premixed mortar for masonry, and mortar joint is laid by workers independently, and the thickness of part of mortar joint exceeds the requirement of specification. Since the maximum thickness of block mortar joint should not exceed 15mm, workers cannot well ensure the uniformity of mortar joint of whole wall during operation, so that it will lead to uneven thickness of mortar joint and arc-shaped mortar joint, affecting overall appearance.

[0010] Further, the positioning mechanism includes a positioning screw, a threaded hole communicated to the through hole is formed above the side plate, and the positioning screw is threadedly connected in the threaded hole.

[0011] Beneficial effects: the positioning screw can tightly press the side plate above the back plate, so as to fix the side plate and the back plate as a whole.

[0012] Further, the first sliding groove is a dovetail groove with small outer diameter and large inner diameter.

[0013] Beneficial effects: prevent the sliding block from being separated from the first sliding groove in the vertical direction of the first sliding groove, so that the sliding block only slides in the extension direction of the first sliding groove.

[0014] Further, the side plate is a right-angled trapezoidal plate, the hypotenuse of the right-angled trapezoidal plate is located at the rear side of the side plate, and the scraper plate is slidingly arranged on the hypotenuse of the side plate.

[0015] Beneficial effects: the inclined arrangement of the scraper plate can make the mortar flow out of the bottom of the scraper plate more smoothly during pulling of the tool.

[0016] Further, the second sliding groove is formed at the upper position of the scraper plate.

[0017] Beneficial effects: avoid that the second sliding groove is too low, so as to cause the mortar to be left in the gap of the second sliding groove during use of the tool, thereby causing waste of the mortar.

[0018] Further, the bottom of the scraper plate is provided with a sawtooth-shaped notch.

[0019] Beneficial effects: the laid mortar can be in a concave-convex staggered state commonly used in construction, and the forming effect of the mortar joint is further ensured.

[0020] Further, a handle is arranged at the front side of the back plate.

[0021] Beneficial effects: facilitate movement and use of the tool. BRIEF DESCRIPTION OF DRAWINGS
