Description

Technical Field

[0001] This invention belongs to the technical field of construction joint control devices, and particularly relates to a construction joint control device. Background Technology

[0002] When constructing masonry, workers use a trowel to evenly apply the mixed mortar to the horizontal and vertical surfaces of the blocks, ensuring the thickness meets the mortar joint standards. Then, the blocks are positioned according to the gauge rod and string line, and are steadily bonded to the mortar layer. Light pressure is applied to fill the gaps with mortar, ensuring full mortar joints and tight bonding between the blocks, thus guaranteeing the integrity and stability of the masonry structure.

[0003] For example, Chinese patent CN208329628U discloses a construction joint control device, belonging to the field of building construction. It solves the problem that existing mortar joint control devices are not suitable for masonry walls of various lengths. The device includes a main body, which comprises a mortar joint control plate placed on the top surface of the masonry wall, a pair of positioning plates set at the bottom of the mortar joint control plate and sandwiched between the two sides of the masonry wall, and a mortar joint groove opened on the mortar joint control plate for forming mortar joints on the top surface of the masonry wall. A rolling component is provided between the main body and the masonry wall. A mortar box for holding mortar is provided on the mortar joint control plate. The mortar box has an opening for mortar to fall into the mortar joint groove. A scraper for leveling the mortar in the mortar joint groove is slidably provided on the mortar joint control plate. As long as mortar is poured into the mortar box and the control device is moved, the mortar in the mortar box will be automatically laid on the masonry wall. It is suitable for masonry walls of any length.

[0004] The above-mentioned patent has the following problems: the adjusting plate in the above-mentioned device is not fixed during use. When laying mortar, the mortar in the mortar box does not fall evenly downwards, which will cause uneven stress on the bricks, forming stress concentration points that lead to single brick cracking or mortar joint cracking, thus destroying the cooperative stress-bearing performance of the masonry.

[0005] To address the technical problems existing in current construction joint control devices, we propose a construction joint control device. Summary of the Invention

[0006] The purpose of this invention is to provide a construction joint control device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a construction joint control device, comprising a housing, a mortar tank, two positioning plates, an adjusting plate, a scraper, and several rollers, wherein a sand outlet is provided in the middle of the housing; the lower opening of the mortar tank communicates with the sand outlet, and further comprises:

[0008] The first sliding groove is formed inside the housing. The two positioning plates are slidably installed on both sides of the sand outlet at the bottom of the housing. The mortar box is fixedly installed on the housing. The adjusting plate is slidably installed inside the mortar box. The scraper is slidably installed on the housing. Several rollers are rotatably installed on the housing and the two positioning plates respectively.

[0009] A sliding plate is slidably installed in a first sliding groove. The adjusting plate has several grooves. The upper end of the sliding plate passes through the first sliding groove and extends into the corresponding groove, and the upper end of the sliding plate is inserted into the corresponding groove.

[0010] A drive assembly, located within the housing, is used to drive the sliding plate to slide.

[0011] A fixing component, located within the housing, is used to fix the position of the scraper and the two positioning plates.

[0012] In this technical solution, when it is necessary to adjust the distance between the two positioning plates to accommodate walls of different widths, the positioning plates can be slid by the fixed components. When the positioning plates slide to the appropriate position, the fixed components can fix the position of the positioning plates, making it convenient to adjust the position of the positioning plates and ensuring that the positioning plates will not be displaced during use, thus ensuring the stability of the mortar falling path.

[0013] When the position of the scraper needs to be adjusted, the scraper can be pulled upward by the fixed component. When the scraper moves to the appropriate position, the fixed component can fix the position of the scraper, which makes it easy to adjust the position of the scraper and ensures that the scraper will not move during use, thus ensuring uniform mortar thickness.

[0014] When the position of the adjusting plate needs to be adjusted, the set drive component can drive the sliding plate to slide downward. After the sliding plate disengages from the corresponding groove, the adjusting plate is pulled to slide. When the adjusting plate slides to the appropriate position, the set drive component can drive the sliding plate to slide upward. Finally, the sliding plate is inserted into the corresponding groove, which can fix the position of the adjusting plate and ensure that the adjusting plate will not be displaced during use, thus ensuring stable mortar drop.

[0015] In the above technical solution, the driving component further includes:

[0016] An L-shaped sliding rod is slidably installed in a first sliding groove. Several guide grooves are formed on the long end of the L-shaped sliding rod, and guide posts are slidably installed in each of these guide grooves. Each guide post is fixedly connected to a sliding plate. The short end of the L-shaped sliding rod protrudes from the first sliding groove and serves as the driving end. Pushing the short end of the L-shaped sliding rod, due to the limiting and guiding effect of the guide posts, can drive the sliding plate to move up and down, thereby enabling the sliding plate to engage with the grooves on different adjustment plates, thus adjusting the sand output.

[0017] Furthermore, the drive assembly also includes two first fixed posts, both of which are fixedly installed at the long end of the L-shaped sliding rod. A first spring is fixedly provided at the end of the two first fixed posts, and the other end of the first spring is fixedly connected to the inner wall of the first sliding groove. This arrangement can realize the rapid reset of the sliding plate.

[0018] In this technical solution, when the position of the adjusting plate needs to be adjusted, the L-shaped sliding rod is first pulled towards the first fixed column. The L-shaped sliding rod drives the two first fixed columns to slide, and the two first fixed columns respectively compress the two first springs to contract. The L-shaped sliding rod drives several guide columns to slide through several guide grooves. The guide columns drive the sliding plate to slide downward. When the sliding plate disengages from the corresponding groove, the adjusting plate is pulled to slide. When the adjusting plate slides to the appropriate position, the L-shaped sliding rod is released. Under the rebound force of the two first springs, the L-shaped sliding rod slides. The L-shaped sliding rod drives several guide columns to slide through several guide grooves. The guide columns drive the sliding plate to slide upward. Finally, the sliding plate is inserted into the corresponding groove, which can fix the position of the adjusting plate and ensure that the adjusting plate will not be displaced during use, thus ensuring stable mortar drop.

[0019] In the above technical solution, the fixing component further includes:

[0020] Two second sliding grooves are respectively opened in two positioning plates. Sliding strips are slidably installed in each of the two second sliding grooves. Several second fixing posts are fixedly installed at the bottom of each of the two sliding strips. Second springs are fixedly installed at the bottom of each of the several second fixing posts. The bottom of each of the several second springs is fixedly connected to the inner wall of the two second sliding grooves respectively.

[0021] Several limiting grooves are provided at the bottom of the housing. The tops of the two sliding bars pass through the two second sliding grooves and extend into the corresponding limiting grooves. The two sliding bars are respectively inserted into the corresponding limiting grooves.

[0022] In this technical solution, when it is necessary to adjust the distance between the two positioning plates to accommodate walls of different widths, firstly, pull down the sliding bar. The sliding bar causes several second fixed columns to slide downwards, while several second springs are compressed and contracted. After the top of the sliding bar disengages from the corresponding limiting groove, the positioning plate is pulled to slide. When the positioning plate slides to the appropriate position, the sliding bar is released. Under the rebound force of several second springs, the sliding bar slides upwards and inserts into the corresponding limiting groove, which can fix the position of the positioning plate, making it convenient to adjust the position of the positioning plate and ensuring that the positioning plate will not shift during use, thus ensuring a stable mortar drop path.

[0023] In the above technical solution, the fixing component further includes:

[0024] The power chamber is located inside the scraper. A sliding block is slidably installed inside the power chamber. A third spring, which is fixed to the inner wall of the power chamber, is fixed to the top of the sliding block. Two connecting rods are rotatably installed at the lower end of the sliding block. Limiting blocks are rotatably installed at the ends of the two connecting rods that are far apart from each other. Several rectangular slots are opened on the housing and on both sides of the scraper. The ends of the two limiting blocks that are far apart from each other pass through the power chamber and extend into the corresponding rectangular slots. The ends of the two limiting blocks that are far apart from each other are respectively inserted into the corresponding rectangular slots.

[0025] In this technical solution, when the position of the scraper needs to be adjusted, the sliding block is pulled upwards, and the third spring is compressed and contracted. The sliding block drives the two connecting rods to rotate, and the two connecting rods respectively drive the two limiting blocks to slide and move closer to each other. After the two limiting blocks are disengaged from their corresponding rectangular slots, the scraper can be pulled upwards. When the scraper is moved to the appropriate position, the sliding block is released. Under the action of the rebound force of the third spring, the sliding block slides downwards, and the sliding block squeezes the two connecting rods to rotate. The two connecting rods respectively squeeze the two limiting blocks to slide and move away from each other. Finally, the two limiting blocks are inserted into their corresponding rectangular slots, which can fix the position of the scraper, facilitate the adjustment of the scraper's position, ensure that the scraper will not be displaced during use, and ensure uniform mortar thickness.

[0026] In the above technical solution, both first fixed posts are slidably connected to the first sliding groove, both limiting blocks are slidably connected to the power cavity, and several second fixed posts are slidably connected to the two second sliding grooves respectively.

[0027] In this technical solution, it is ensured that both first fixed posts can slide within the first sliding groove, both limiting blocks can slide within the power cavity, and several second fixed posts can slide within the two second sliding grooves respectively.

[0028] In the above technical solution, furthermore, the plurality of grooves and the plurality of rectangular grooves are distributed at equal intervals on the shell, and the plurality of limiting grooves are distributed at equal intervals inside the shell.

[0029] In this technical solution, it is ensured that both the adjusting plate and the scraper can be adjusted to any position, and that both positioning plates can be moved to the appropriate position.

[0030] In the above technical solution, the guide groove is further provided at an inclination.

[0031] In this technical solution, the L-shaped sliding rod is ensured to drive several guide posts to slide through several guide grooves, and the guide posts drive the sliding plate to slide downward.

[0032] The beneficial effects of this invention are:

[0033] 1. This construction joint control device allows for adjustment of the distance between two positioning plates to accommodate walls of different widths. A fixing component allows the positioning plates to slide, and when they reach the desired position, the fixing component secures them, facilitating adjustment and ensuring the plates do not shift during use, thus guaranteeing a stable mortar drop path. Similarly, when adjusting the scraper's position, the fixing component allows for upward pulling, and when the scraper reaches the desired position, the fixing component secures it, again facilitating adjustment and ensuring uniform mortar thickness.

[0034] 2. When the position of the adjustment plate needs to be adjusted, the sliding plate can be driven downward by the set drive component. After the sliding plate disengages from the corresponding groove, the adjustment plate is pulled to slide. When the adjustment plate slides to the appropriate position, the sliding plate can be driven upward by the set drive component. Finally, the sliding plate is inserted into the corresponding groove, which can fix the position of the adjustment plate and ensure that the adjustment plate will not be displaced during use, thus ensuring stable mortar drop.
