Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a positioning clamp for controlling the thickness of mortar joints in aerated concrete block walls. Background Technology

[0002] Aerated concrete block walls are a type of wall material that uses aerated concrete blocks. With the rise of energy conservation, environmental protection, and green building concepts, aerated concrete blocks, as a new type of building material, have been widely used in many countries. Especially in the process of rapid urbanization, low-carbon and environmentally friendly building materials are increasingly favored.

[0003] During the construction of aerated concrete block walls, the thickness of the mortar joints directly affects the stability and aesthetics of the wall. In traditional construction methods, the thickness of the mortar joints is controlled solely by the workers' experience. However, improper operation or misjudgment can easily lead to uneven mortar joint thickness, which not only affects the overall structural stability of the wall but also its overall appearance. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning clamp for controlling the thickness of mortar joints in aerated concrete block walls. The positioning clamp has a simple structure, is easy to operate, and can flexibly adjust the thickness of mortar joints as needed, ensuring that the mortar joint thickness of aerated concrete block walls is consistent, thereby improving the stability and appearance consistency of the walls.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A positioning clamp for controlling the thickness of mortar joints in aerated concrete block walls includes a positioning clamp body. The positioning clamp body is composed of two inclined plates spliced ​​together in a V-shape. A vertical plate is provided on the front side of the positioning clamp body. The top and bottom of the vertical plate are connected to the positioning clamp body via a pivot. An adjusting block is slidably connected inside the positioning clamp body. An adjusting screw is connected to the front side of the adjusting block via a bearing. The front end of the adjusting screw extends through to the front side of the vertical plate and is threaded into the interior of the vertical plate. Connecting plates are connected to the top and bottom of the adjusting block. The other end of each connecting plate extends through to the top and bottom of the positioning clamp body, and a positioning plate is fixedly connected to the other end of the connecting plate. The positioning plates are located at the top and bottom of the positioning clamp body, respectively.

[0007] Preferably, the top and bottom of the adjusting block are provided with movable grooves, the end of the connecting plate is slidably connected to the inner wall of the movable groove, a compression spring is fixedly connected to the rear side of the inner wall of the movable groove, and the other end of the compression spring is fixedly connected to the connecting plate.

[0008] Preferably, a limiting strip is fixedly connected to the inner wall of the positioning card body, and the adjusting block is located inside the limiting strip.

[0009] Preferably, a rotating knob is fixedly connected to the end of the adjusting screw, and the rotating knob is round.

[0010] Preferably, the top and bottom of the positioning card body are provided with horizontal grooves, and the connecting plates are slidably connected to the inside of the horizontal grooves.

[0011] Preferably, the top and bottom of the positioning card body are provided with anti-slip grooves, which are evenly distributed on the top and bottom of the positioning card body.

[0012] Preferably, the rear end of the adjusting block is smaller than the front end, and the adjusting block is conical in shape.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when construction workers are building a wall, the rear side of the positioning card body can be inserted between two aerated concrete blocks, ensuring that the mortar joint thickness between the aerated concrete blocks is uniform and avoiding errors that may occur during manual adjustment. At the same time, construction workers can flexibly adjust the thickness of the positioning card body as needed. During adjustment, the adjusting screw can be rotated backward. The rotation of the adjusting screw will cause the adjusting block to be squeezed backward. The adjustment block moves backward, which can squeeze the positioning card body to expand and break the positioning card body, increasing the interval between the positioning card bodies. Thus, the interval between the positioning card bodies can be adjusted according to different block specifications to ensure that the mortar joint thickness meets different construction standards.

[0015] In this invention, after the positioning card body is inserted into the brick joint between the aerated concrete blocks, it can press the positioning plate forward according to the thickness of the aerated concrete block, and cause the positioning plate to drive the connecting plate to slide forward inside the movable groove. At the same time, it will compress the compression spring, and under the elastic force of the compression spring, it can push the connecting plate and the positioning plate to move backward, so that the positioning plate and the aerated concrete block can be tightly fitted. Under the obstruction of the positioning plate, the aerated concrete block can be fixed in the predetermined position, preventing the aerated concrete block from shifting and causing uneven mortar joint thickness, which would affect the stability of the wall.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4As shown, a positioning clamp for controlling the mortar joint thickness of aerated concrete block walls includes a positioning clamp body 1, which is composed of two inclined plates spliced ​​together in a V-shape. A vertical plate 101 is provided on the front side of the positioning clamp body 1. The top and bottom of the vertical plate 101 are connected to the positioning clamp body 1 via pivots. An adjusting block 102 is slidably connected inside the positioning clamp body 1. An adjusting screw 103 is connected to the front side of the adjusting block 102 via a bearing. The front end of the adjusting screw 103 extends through to the front side of the vertical plate 101 and is threadedly connected to... Inside the upright plate 101, the top and bottom of the adjusting block 102 are connected to connecting plates 104. The other end of each connecting plate 104 extends through to the top and bottom of the positioning card body 1, and the other end of the connecting plate 104 is fixedly connected to a positioning plate 105. The positioning plates 105 are located at the top and bottom of the positioning card body 1, respectively. By splicing the two inclined plates, the positioning card body 1 is positioned, making it convenient for construction workers to insert the positioning card body 1 into the brick joint of the aerated concrete block. At the same time, it will press the positioning plate 105 forward. After the positioning plate 105 is pressed, it will drive the connecting plate 105 to move forward. Plate 104 moves forward and compresses the compression spring 202. The compression spring 202, under its own elastic force, pushes the connecting plate 104 and the positioning plate 105, causing the positioning plate 105 to fit tightly against the aerated concrete block. This allows the aerated concrete block to be fixed in a predetermined position by the positioning plate 105, preventing displacement and uneven mortar joint thickness that could affect the stability of the wall. Then, rotating the adjusting screw compresses the adjusting block 102, causing it to move backward between the positioning card bodies 1. This opens and separates the rear side of the positioning card bodies 1, thus... The gap between the main bodies 1 of the positioning card can be increased, and the thickness of the wall mortar joint can also be increased. This allows the thickness of the mortar joint to be adjusted according to the actual situation, ensuring that the mortar joint between each layer of blocks is consistent and avoiding human error. After the aerated concrete block wall is built, the construction workers can turn the adjusting screw 103 forward. The adjusting screw 103 will drive the adjusting block 102 to move forward, and then the gap between the main bodies 1 of the positioning card can be reduced. Finally, the main body 1 of the positioning card can be smoothly pulled out from the brick joint of the aerated concrete block for repeated use.

[0024] like Figure 3As shown, the top and bottom of the adjusting block 102 are provided with movable grooves 201. The end of the connecting plate 104 is slidably connected to the inner wall of the movable groove 201. A compression spring 202 is fixedly connected to the rear side of the inner wall of the movable groove 201. The other end of the compression spring 202 is fixedly connected to the connecting plate 104. When the adjusting block 102 moves backward to adjust the gap of the positioning card body 1, the movable groove 201 at the top of the adjusting block 102 will slide with the connecting plate 104 to avoid the adjusting block 102 from moving and causing the connecting plate 104 to move and collide with the aerated concrete block, thus preventing it from being unable to adapt to aerated concrete blocks of different thicknesses. Therefore, under the action of the compression spring 202, it can automatically adapt to aerated concrete blocks of different thicknesses and position aerated concrete blocks of different thicknesses, thereby improving the flexibility and convenience of construction.

[0025] like Figure 1 and Figure 2 As shown, a limiting strip 3 is fixedly connected to the inner wall of the positioning card body 1. The adjusting block 102 is located inside the limiting strip 3. When the adjusting block 102 moves, it can move smoothly parallel to the limiting strip 3 inside the positioning card body 1 under the auxiliary guidance of the limiting strip 3, ensuring that the adjusting block 102 will not exceed the predetermined movement trajectory when it moves, and avoiding the adjusting block 102 from leaving the positioning card body 1 due to lack of limiting guidance when it moves, thus affecting its normal use.

[0026] like Figures 1-3 As shown, a rotating knob 4 is fixedly connected to the end of the adjusting screw 103. The rotating knob 4 is round. The gap of the positioning card body 1 can be adjusted by rotating the rotating knob 4. This allows for better control of the movement of the adjusting screw 103, ensuring its stability during movement. The adjustment can be completed quickly by rotating the rotating knob 4 without the need for other tools, thus reducing construction time and improving construction efficiency.

[0027] like Figure 1 and Figure 4 As shown, the top and bottom of the positioning card body 1 are provided with transverse grooves 5. The connecting plate 104 is slidably connected to the inside of the transverse grooves 5. The transverse grooves 5 provide sufficient sliding tracks for the connecting plate 104, ensuring that the connecting plate 104 can slide smoothly between the top and bottom of the positioning card. Through this guidance, the movement trajectory of the connecting plate 104 becomes more stable, avoiding the situation of jamming or unsmooth movement caused by insufficient space for the connecting plate 104 during movement.

[0028] like Figure 1 and Figure 4As shown, anti-slip grooves 6 are provided on the top and bottom of the positioning card body 1, and are evenly distributed on the top and bottom of the positioning card body 1. The design of anti-slip grooves 6 can increase the friction between the positioning card body 1 and the aerated concrete block, and prevent the positioning card body 1 from slipping during construction. Especially when adjusting the mortar joint or laying the block, it avoids structural errors or instability caused by slipping.

[0029] like Figures 1-3 As shown, the rear end of the adjusting block 102 is smaller than the front end. The adjusting block 102 is conical in shape. When adjusting the gap of the positioning card body 1 and the size of the brick joint, the adjusting block 102 can be continuously pushed backward. With the size of the adjusting block 102 being smaller at the front and larger at the back, the gap of the positioning card body 1 can be smoothly and accurately adjusted. Moreover, with its gradually widening shape, more subtle adjustments can be easily achieved during the adjustment process.

[0030] The working principle of this utility model is as follows: When construction workers are building a wall, they can insert the rear side of the positioning card body 1 between two aerated concrete blocks to ensure that the mortar joint thickness between the aerated concrete blocks is uniform, avoiding errors that may occur during manual adjustment. At the same time, construction workers can flexibly adjust the thickness of the positioning card body 1 as needed. During adjustment, the adjusting screw 103 can be rotated backward. The rotation of the adjusting screw 103 will drive the adjusting block 102 to be squeezed backward. The adjustment block 102 moves backward, which can squeeze the positioning card body 1 to expand, and cause the positioning card body 1 to break apart and increase the interval of the positioning card body 1. Thus, the interval of the positioning card body 1 can be adjusted according to different block specifications to ensure that the mortar joint thickness meets different construction standards.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
