Description

Technical Field

[0001] This utility model belongs to the field of masonry construction technology, specifically relating to an auxiliary positioning clamp for mortar brick joints. Background Technology

[0002] At present, secondary structure masonry is becoming increasingly popular in the construction field. The application of aerated concrete blocks has solved the problems of slow construction speed and large verticality deviation of traditional bricks. Moreover, aerated concrete blocks are lighter and more convenient for rapid construction.

[0003] However, the incomplete mortar jointing of aerated concrete blocks, resulting in blind joints, through joints, and false joints, is a major problem that many construction companies cannot solve. For example, the mortar jointing process is slow, leading to incomplete and uneven joints; moreover, workers need to lay the blocks one shovelful at a time, resulting in slow construction speed and significant material waste; furthermore, the spacing between aerated concrete blocks is controlled visually by workers, leading to uneven gaps on the surface of the secondary structure masonry.

[0023] This utility model provides an embodiment:

[0024] like Figures 1 to 4 As shown, an auxiliary positioning clamp for mortar brick joints includes a positioning component and an auxiliary telescopic component. The positioning component includes two parallel semi-positioning members, each semi-positioning member comprising a brick joint clamping strip 1, a mortar joint clamping plate 2, and a stop strip 3. The brick joint clamping strip 1 is perpendicular to the cross-section of the mortar joint clamping plate 1 and fixed to the front end of the mortar joint clamping plate 1. The stop strip 3 is perpendicular to the vertical cross-section of the mortar joint clamping plate 1 and is fixed along the entire length of the inner side of the mortar joint clamping plate 1. The top surface of the stop strip 3 is a downward-facing slope. The auxiliary telescopic component is connected to the ends of the two semi-positioning members and can move the two semi-positioning members closer to or further apart. The thickness of the mortar joint clamping plate 1 is equal to the thickness of the mortar joint between two adjacent aerated concrete blocks.

[0025] In this embodiment, the auxiliary telescopic assembly includes an end rod 4, an inner rod 5, an outer tube 6, and a hand clamp; wherein the two end rods 4 are respectively fixed to the ends of the two mortar joint plates 1 and extend along their length direction, the inner rod 5 is slidably connected to the outer tube 6, the structure composed of the two sets of inner rods 5 and outer tubes 6 is arranged in parallel and connected between the two end rods 4, and the hand clamp is connected between the two sets of inner rods 5 and outer tubes 6 and is used to change the relative position between the inner rods 5 and outer tubes 6 in the same group.

[0026] The handheld clamp includes a push plate I7, a push plate II8, an X-bracket 9, and a handle 10. Push plates I7 and II8 partially overlap. The first end of push plate I7 ​​is fixed to the inner insert rod 5, and a long slot I7.1 is located near the first end of push plate I7. The second end of push plate I7 ​​has a pin I7.2. The first end of push plate II8 is fixed to the outer sleeve 6, and a long slot I18.1 is located near the first end of push plate II8. The second end of push plate II8 has a pin I18.2. Pin I7.2 and long slot I18.1 are slidably engaged. The two X-brackets 9 share a common rotating shaft 12, and the lower ends of the two rods of the X-bracket 9 are respectively engaged with pins I7.2 and I18.1. The I8.2 connection connects the lower parts of the two rods of the X-bracket 9 via spring 11, and the handle 10 is connected to the upper part of the two rods of the X-bracket 9. When the spring 11 is in its initial state, the width between the two mortar joint plates 2 is less than the width of a single aerated concrete block.

[0027] Working principle:

[0028] The bottom surface of the retaining strip 3 and the mortar joint clamp 2 form an inside corner that is clamped onto the top edge of the lower aerated concrete block. Because the bottom surface of the retaining strip 3 is in contact with the top surface of the lower aerated concrete block, it can position the upper and lower positions of the auxiliary mortar joint positioning clamp. The mortar joint clamp 2 is in contact with the side of the lower aerated concrete block, thus it can position the front and back positions of the auxiliary mortar joint positioning clamp. The brick joint clamp 1 is attached to the aerated concrete block of the same layer, thus it can position the left and right positions of the auxiliary mortar joint positioning clamp. The top surface of the lower aerated concrete block and the area between the two mortar joint clamps 2 form a mortar-laying area. The mortar in the mortar hopper is poured into the mortar-laying area and then leveled. Then, the aerated concrete block is placed against the brick joint clamp 1, and the two mortar joint clamps 2 are moved away from each other, so that the retaining strip 3 and the brick joint clamp 1 can be removed from between the two aerated concrete blocks. The top surface of the retaining strip 3 is set as a downward-facing slope to facilitate removal from between the aerated concrete blocks.

[0029] When the two rods of the X-bracket 9 are close together, the inner rod 5 is pushed out of the outer tube 6 by the push plate I7 ​​and the push plate I18, and the two end rods 4 are far apart. When the two rods of the X-bracket 9 are far apart, the inner rod 5 is pulled into the outer tube 6 by the push plate I7 ​​and the push plate I18, and the two end rods 4 are close together. The upper ends of the two rods of the two X-brackets 9 are connected by a handle 10. By holding the two handles 10 and applying force, the two rods of the two X-brackets 9 are brought close together.

[0030] A spring 11 is connected between the two rods of the X-bracket 9. The spring 11 pushes the two rods of the X-bracket 9 away from each other. That is, when there is no external force at the handle 10, the elastic force of the spring 11 makes the two rods of the X-bracket 9 move away from each other and the two end rods 4 move closer together, so that the two mortar joint clamps 2 can be clamped on the aerated concrete block.

[0031] By changing the force direction of the inner rod 5 and the outer tube 6 by pushing plate I7 ​​and pushing plate I18, the two end rods 4 are far apart when the two rods of the X bracket 9 are subjected to the gripping force of the palm, which conforms to people's usage habits and makes it easier to operate the mortar brick joint positioning clamp with one hand.

[0032] Practice has proven that this auxiliary positioning clamp for mortar brick joints is simple to manufacture, quick to install and remove, aesthetically pleasing, environmentally friendly and pollution-free, and reusable. This auxiliary positioning clamp for mortar brick joints is simple, highly feasible, and possesses good safety and durability. It saves costs and time, offering significant technical, economic, and social benefits. In particular, it effectively prevents common quality defects during construction and has great application potential.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
