Technical Field
[0001] The utility model relates to the technical field of building masonry structures, in particular to a skin number rod for adjusting mortar joints of masonry. Background Art
[0002] During the reconstruction of building masonry structures, it is necessary to determine the number of layers of blocks according to the height of the masonry and adjust the thickness of the mortar joints accordingly. The skin number rod is an important construction auxiliary tool in the construction of masonry projects and is widely used. Common block specifications are: ① Standard brick 240×115×53mm; ② Concrete hollow block 390×190×190mm, there are 240×200×115mm and 240×120×115mm in the market; ③ Sintered hollow brick 200×190×115mm, 240×190×100mm, 240×200×190mm; ④ Small block 190×90×90mm; ⑤ Sound insulation block 240×115×60mm; ⑥ Self-insulating hollow block 240×115×90mm; ⑦ Aerated concrete block length is generally 600mm, width 75-250mm (increases by 25), height 200mm, 250mm, 300mm. Because the specifications of different types of blocks are different, the number of block skins required for a certain height is different. In addition, walls made of different masonry materials or walls of different heights all need to be made and set up separately. Conventional skin number rods are single and do not have wide applicability. Often a project takes time, effort, and money to make skin number rods of various sizes and modules. Even a floor needs to make multiple skin number rods due to different wall designs. Conventional skin number rods may be used up in a project or a floor and cannot be adapted to other masonry, so they have to be abandoned, causing great waste and inconvenience in construction. The utility model is proposed based on the above research background, and aims to provide a skin number rod for adjusting mortar joints in masonry to meet actual use needs. Utility Model Content

A level bubble (8) is also provided on the outer surface of the frame. The top end of the supporting tripod is hingedly arranged on the outer peripheral surface of the middle part of the frame through a universal bearing (9). The bottom of the frame is also provided with a plurality of leveling nuts (10). The support tripod is a telescopic support rod with adjustable length, and the end away from the hinge is provided with a conical end. The outer surface of the frame is also provided with scale marking lines (11) at equal intervals along the length direction of the transmission screw. The transmission screw is also provided with a hand nut (12) for locking at a position close to the top of the frame, and the hand nut is located inside the frame. The leather counting rod also includes a laser emitter (14), and each slider is also provided with a wedge block (13), and each wedge block is provided with an installation groove for installing the laser emitter (14), and the laser emitter can be detachably installed in any installation groove.
[0019] When the skin counting rod of the utility model is used, the specific method is as follows:
[0020] The slider is linked by a Z-shaped folding line linkage mechanism. The adjusting hand wheel at the top of the screw rod rotates the middle screw rod and the nut on the top slider to form a screw rod-slider transmission, so that all sliders can be equally spaced up and down. As long as the horizontal height of the top slider is controlled to be equal to the height of the masonry, the thickness of each layer of blocks can be evenly divided. When laying masonry, it is only necessary to calculate the appropriate number of layers of blocks according to the height of the wall, and then by turning the adjusting hand wheel to make the center line of the corresponding top slider flush with the equal wall height scale line, the thickness of each layer of blocks can be controlled to be uniform during the construction of different masonry structures, and the spacing between sliders on each layer and the thickness of the mortar joints of the blocks can be adjusted intuitively and evenly. When in use, the skin number rod needs to be erected at one end of the wall to be built (both ends of the long wall frame) and ensure that there is no obstruction. The corresponding lowest slider height is adjusted to be equal to the thickness of the first layer of blocks through the bottom leveling bolts. At the same time, the frame is adjusted to be vertical in the X direction. The right support point is found by swinging the tripod left and right to support it on the ground. At the same time, the Y direction is adjusted to be vertical and stable by changing the length of the telescopic rod. It is locked by the telescopic node locking device. Observe whether the centering bubble is centered. If it is not centered, make fine adjustments. After the centering, the frame is erected. When laying, insert the laser launcher into the center wedge groove of the slider corresponding to the height of the masonry, turn on the laser launcher to launch the horizontal line, and control each layer of blocks to be on a horizontal plane.
[0021] Take a brick wall with a masonry height requirement of 980mm as an example. The specification requires a mortar joint thickness of 8-12mm. After calculation, 16 layers of bricks are suitable. The layer number rod is set up and leveled so that the 980 scale on the rod is consistent with the top elevation of the wall to be built. The hand wheel is rotated to align the center line of the 16th slider with the 980 scale. The laser launcher is installed in the first slider to launch the laser to lay the first layer of bricks. After completion, the laser launcher is installed in the second slider to launch the laser to lay the second layer of bricks, ... until the 16th layer of bricks is completed. The masonry height is 980mm, the thickness of each layer of masonry is 61.25mm, and the thickness of the mortar joint is 8.25mm; the mortar joint is uniform and the masonry is beautiful; after the wall is built, the layer number rod is moved to the next masonry point and the next wall is built in the same way. Through application and practice, a set of layer number rods has been used in all masonry construction of the project, which has increased the turnover rate of the layer number rods and verified their wide applicability. Because the masonry work is small, the economic benefits are not prominent. The production cost of the leather number rod of the utility model is 300 yuan per set, and the conventional leather number rod is 120 yuan per set. In contrast, the utility model can reflect its cost saving value by turnover more than 2.5 times.
[0022] Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the utility model.
