[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Please refer to the attached Figure 1 to the attached Figure 3 , a device for laying and pointing mortar for masonry, comprising a bracket 1, a baffle 2 and a mortar scraping baffle 3; a pair of brackets 1 are perpendicularly connected to a pair of mortar scraping baffles 3 to form a rectangular frame structure, a pair of baffles 2 are respectively arranged on a pair of brackets 1, and a raised edge 201 is formed along the entire length at one side edge of the pair of baffles 2, and the raised edge 201 extends towards the inside of the rectangular frame structure, so that when the pair of baffles 2 are respectively placed on the two side edges of the top surface of the building block 6 through the raised edge 201, the pair of brackets 1 are respectively attached to the two side surfaces of the building block 6, and the pair of mortar scraping baffles 3 are respectively located above the top surface of the building block 6; the mortar 7 is laid on the top surface of the building block 6, so that the pair of baffles 2 squeeze the two side edges of the mortar 7 through the raised edge 201 to form a mortar joint, and the bottom surface of the mortar scraping baffle 3 can be inserted into the mortar 7.

[0023] Preferably, the bracket 1, the baffle 2 and the mortar scraping baffle 3 can be made of wood materials, and can be connected into a whole through connecting pieces 5 such as bolts and nuts. According to the sizes of different building blocks 6 and the sizes of the masonry walls, a rectangular frame structure can be adaptively manufactured, so that the rectangular frame structure can be erected on the top of the already masoned building blocks 6 and can be pulled and translated along the length direction of the wall.

[0024] A pair of baffles 2 can be placed on the two side edges of the top surface of the building block 6 through the raised edge 201, so as to squeeze the mortar 7 inward through the raised edge 201 to achieve the purpose of pointing. A pair of brackets 1 are attached to the two side edges of the building block 6 to play the role of guiding and limiting, so as to ensure the uniformity, consistency and aesthetics of the two-side pointing.

[0025] The distance between the bottom of the mortar scraping baffle 3 and the building block 6 can be determined according to the width of the mortar joint. When the construction worker lays the mortar 7, the thickness of the mortar 7 can be made greater than the width of the mortar joint. The bottom of the mortar scraping baffle 3 is inserted into the mortar 7. Thus, when the rectangular frame structure is moved, the mortar scraping baffle 3 scrapes the mortar 7 to spread and form the mortar 7 to meet the width requirement of the mortar joint.

[0026] Please refer to the appendix Figure 1 and the appendix Figure 2 , both ends of the described bracket 1 extend upward respectively to form bent mounting parts 101. The end of the mortar scraping baffle 3 is fixedly connected to the bent mounting part 101 through a connecting piece 5, and the mortar scraping baffle 3 is arranged higher than the bracket 1.

[0027] The bent mounting part 101 extends upward above the bracket 1, which is convenient for installing the mortar scraping baffle 3.

The height of the wavy serrated structure 301 is 30% of the width of the mortar joint.

[0029] The wavy serrated structure 301 is used to scrape the mortar 7, making the spreading of the mortar 7 more uniform and the spreading effect better.

[0030] Please refer to the appendix Figure 3 , the cross-section of the raised edge 201 of the described baffle 2 has a semi-circular structure, and the diameter of the semi-circular structure is the same as the width of the mortar joint.

[0031] The raised edge 201 with a semi-circular structure is used to squeeze the mortar 7 inward, so as to achieve the purpose of caulking, and the caulking can be made uniform and beautiful. While pulling the rectangular frame structure, the baffle 2 and its raised edge 201 move synchronously with the rectangular frame structure, so that the spreading and caulking of the mortar 7 are completed synchronously.

[0032] Please refer to the appendix Figure 3 , handles 4 are respectively installed on the tops of the pair of mortar scraping baffles 3 through connecting pieces 5.

[0033] The handle 4 can be made of materials such as wood and plastic, which is convenient for holding and pulling to control the rectangular frame structure.

[0034] The length of the described mortar scraping baffle 3 is the same as the width of the building block 6, ensuring that the pair of brackets 1 can translate while fitting the two side surfaces of the building block 6.

[0035] The length of the described support 1 is greater than the length of the building block 6. The baffle 2 is arranged longitudinally on the support 1 and is located between the bent mounting parts 101 at both ends of the support 1.

[0036] Preferably, the length of the support 1 can be 1.5 times the length of the building block 6. The length of the support 1 can be adjusted adaptively according to actual needs, which is convenient for pulling and controlling the rectangular frame structure and improving the spreading and jointing efficiency of the mortar 7.

[0037] Please refer to Appendix Figure 1 to Appendix Figure 3 , taking the building block 6 with dimensions of 390*190*190 mm for building the wall and the mortar joint width of 10 mm as an example, the usage method and working principle of the present utility model are as follows:

[0038] The width of the building block 6 is 190 mm, so the wall thickness is 190 mm. The distance between a pair of supports 1 is 190 mm. The length of the support 1 can be designed as 600 mm, the thickness of the support 1 is 20 mm, and the total height of the support 1 and its bent mounting part 101 is 20 mm. The length of the mortar scraping baffle 3 is 190 mm, and the height of the wavy serrated structure at the bottom of the mortar scraping baffle 3 is 3 mm.

[0042] The construction workers lay an appropriate amount of mortar 7 on the top surface of the building block 6 and within the rectangular frame structure, hold the handle 4 and pull the rectangular frame structure along the length direction of the wall, so that the wavy serrated structure at the bottom of the mortar scraping baffle 3 spreads the mortar 7. At the same time, a pair of baffles 2 squeeze the mortar 7 from both sides through the protruding semi-circular structure to achieve the purpose of caulking. The caulking depth is 5 mm, so that the mortar 7 forms a mortar joint with uniform thickness on the top surface of the building block 6, and the forming effect of the mortar joint is good.

[0043] Along the length direction of the wall, while laying the mortar 7, pull the rectangular frame structure, pull the rectangular frame structure from one end of the wall to the other end to form a continuous mortar joint, and remove the rectangular frame structure, then the masonry construction of the upper layer of building blocks 6 can be carried out.

[0044] Repeat the above operations, layer by layer, to build the building blocks 6 upwards until the overall masonry of the wall is completed.
