For example, the adjusting screw 240 is rotated to vertically move the control steel plate 40 upward until the scale mark 10mm of the control steel plate 40 is flush with the lower edge of the limiting steel plate 50, which means that the average thickness of the horizontal mortar joint mortar is 10mm, and when the constructor drags the mortar spreading device by using the carrying handle 210, the mortar can be uniformly spread on the masonry surface of the brick wall with the thickness of 10 mm.

Based on this, this embodiment also provides a construction method of the grout spreading device, including:

step S1: a constructor carries out laying according to the length and the height of each filler wall masonry, determines the thickness of each horizontal mortar joint and the width of a vertical joint, and then builds a first bottommost building block according to the laying condition;

step S2: hanging a second skin building block horizontal masonry line;

step S3: rotating a control steel plate of the mortar spreading device to 0 position of a scale mark, and pushing the ash blocking plate to the foremost end to seal the through hole so as to prevent mortar from leaking;

step S4: pouring the stirred masonry mortar into a mortar spreading device, wherein a constructor uses both hands to carry lifting handles at two ends of the mortar spreading device, the mortar spreading device is lifted to one end of a first skin building block, then a mortar blocking plate of the mortar spreading device is pulled to the rearmost end to open the through opening, and the mortar gap thickness determined when the scale mark of the control steel plate is rotated to the bottom of the mortar spreading device is dragged by the lifting handles, so that the mortar spreading device can be easily dragged under the rolling of a bearing, the mortar is uniformly spread on a masonry surface, the mortar gap thickness is uniform, and the mortar is full;

step S5: and after a skin building block is built, repeating the steps and sequentially building the upper building block.

The effect contrast of using the shop's thick liquid device that this embodiment provided and using the grey shovel to build by laying bricks or stones is as follows:

1) and (5) comparing the building efficiency. The mortar storage barrel of the mortar paving device can be filled with 0.03 cubic meter of mortar, the time of about 20 seconds is needed for paving the mortar on the masonry surface completely and uniformly, and after paving is finished, the building blocks can be adjusted easily to meet the standard requirements. The time of paving 0.03 cubic meter of mortar in a hopper by manually using an ash shovel, a shovel and a shovel is about 60 seconds, and the building block adjustment needs to take longer time to meet the standard requirement due to uneven thickness of the mortar during manual paving. By comparison, the masonry efficiency is improved by about 3 times by using the mortar spreading device compared with that by using the ash shovel.

2) Comparing the labor intensity of workers. The mortar can be uniformly paved on the masonry surface by using the mortar paving device and only dragging the carrying handle easily. When mortar is paved by manually shoveling mortar by one shovel, hundreds or even thousands of 'straight waist and bending waist' actions are finished by workers every day. As can be seen by comparison, the labor intensity of workers can be greatly reduced by using the slurry paving device.

3) And (5) comparing the masonry quality. The mortar spreading device can enable the thickness of each horizontal mortar joint to be uniform and consistent, the mortar is full, in the moving process, the vertical rod of the mortar spreading device reaches the position of the vertical joint, the vertical joint mortar can be immediately filled by using a vertical joint filling tool by utilizing the blocking of the vertical rod, and the vertical joint mortar is tightly filled. The mortar paved by manually shoveling one shovel by using the mortar shovel has the defect that the thickness and the mortar plumpness of the mortar at the horizontal mortar joint are difficult to control effectively due to the uneven thickness of the mortar paved manually. It can be seen through the comparison that the use of the mortar spreading device can significantly improve the masonry quality.

4) And (5) comparing mortar loss. When the mortar paving device is used for building mortar, the cross bars with the length of 100mm are arranged on the two sides of the fixed support, so that the mortar is prevented from falling, and the mortar loss can be almost zero. The mortar paved by manually shoveling mortar by shoveling mortar and paving mortar by shoveling, and the loss rate is about 2.5 percent. As can be seen by comparison, the mortar loss can be greatly reduced by using the mortar spreading device, so that the mortar loss is almost zero.
