Description

Technical Field

[0001] The invention relates to the field of measurement technology, in particular to a positioning and measuring device for floor tile paving construction. Background Art

[0002] Floor tiles are a kind of floor decoration material made of fired clay. They have various specifications, are hard, pressure-resistant, wear-resistant, moisture-proof, and have decorative effects. They are mostly used on the floors and floors of public and civil buildings. When pasting wall and floor tiles, especially open-slit paving, the mortar joints are often uneven in width, which can easily cause the floor tiles to shift and tilt, affecting the appearance and increasing the subsequent rework rate. Therefore, a positioning and measuring device is needed to assist the staff in the paving construction.

[0003] Referring to a floor tile laying positioning and measuring device disclosed in the patent with reference to publication number CN105865429B, the present invention is first fixed at the four corners of the room where floor tiles are to be laid, and after the room is squared by the infrared device on the upper part, the positions of the brick blocks are marked on the wall for construction. Construction is carried out from the inside to the outside, which can eliminate the common quality defect of large deviation in the flatness of the floor tiles caused by the traditional long pull line and the lower support in the middle.

[0004] At present, level meters are mostly used to replace traditional layout construction for floor tile construction. For example, the above-mentioned positioning and measuring device also uses an infrared device and a balance frame to complete the measurement work. However, the above-mentioned positioning and measuring device has great limitations in operation and cannot be quickly attached to a floor tile to complete the subsequent paving and positioning work. In addition, the assembly and debugging of the balance frame is heavy. Errors in debugging can easily affect the overall paving of the floor tiles. At the same time, the overall footprint is large, which is inconvenient to use. It cannot effectively adapt to different room types for adaptation and adjustment, and is inconvenient for construction personnel to operate. Summary of the invention

Since the limit piece 8 is composed of a clamping piece part 801 and a pressing part 802, the clamping piece part 801 extends into the mortar joint of the floor tiles, which will not interfere with the subsequent paving. The pressing part 802 is protruding from the clamping piece part 801, which can press and position adjacent floor tiles to maintain the levelness of adjacent floor tiles; The adjusting plate 3 moves up and down in the positioning ring 1 through threads. Specifically, an internal thread area is provided in the positioning ring 1, an external thread area is provided on the outer wall of the adjusting plate 3, a handle 9 is installed on the top of the adjusting plate 3, a guide ring 10 is rotatably installed on the upper surface of the adjusting plate 3, and a plurality of delivery pipes 11 are connected around the annular cavity 4, and a manual valve for controlling the on-off of each delivery pipe 11 is installed at the end of each delivery pipe 11; It is worth noting that when the positioning ring stage 1 is adsorbed and fixed: first, the handle 9 is turned to make the adjustment plate 3 move downward in the positioning ring stage 1, and the pull rope 14 is moved through the guide wheel 13 to pull the two pulling rods 12 upward to control the extrusion ring 6 to move upward in the annular cavity 4. Due to the upward movement of the extrusion ring 6, a certain adsorption force is formed at the bottom of the annular cavity 4, thereby ensuring the stability of the positioning ring stage 1; In an embodiment of the present invention, the pulling member comprises: Two pulling rods 12 are symmetrically slid through the top of the annular cavity 4 and are detachably fixedly connected to the extrusion ring 6; Two guide wheels 13 are symmetrically mounted on both sides of the top of the positioning ring platform 1 through a bracket, and pull ropes 14 are installed on the top of the two pulling rods 12.

[0025] like Fig. 9 and Fig.10 As shown, the moving part includes: Two slide plates 17 are symmetrically slidably engaged on both sides of the adjusting chamber 15. A switching area 18 is provided on one side of the inner wall of the adjusting chamber 15. A switching gear 19 is rotatably installed in the middle position of the switching area 18. A rack 20 is slidably mounted on the top of the switching area 18. The rack 20 is detachably fixedly connected to a slide 17. A rack 21 is slidably mounted on the bottom of the switching area 18. The rack 21 is detachably fixedly connected to another slide 17. Both the rack 20 and the rack 21 are meshed with the switching gear 19. In the embodiment of the present invention, the moving part further includes: The extrusion chamber 22 is installed at the middle position of the adjustment chamber 15 through a bracket. An extrusion rod 23 connected to one of the slides 17 is slidably installed in the extrusion chamber 22. An introduction pipe 24 is installed at the tail of the extrusion chamber 22. The introduction pipe 24 is connected to the delivery pipe 11 through a spring tube. A return spring 25 is installed between the extrusion rod 23 and the extrusion chamber 22. It is worth noting that: when multiple positioning units are synchronously controlled: when the annular cavity 4 moves upward, the medium therein is conveyed to the movable parts of each limiting plate 8 through the conveying pipe 11, and is sent into the extrusion cavity 22 through the introduction pipe 24, so as to push the extrusion rod 23 to extend, and push one of the slide plates 17 to move.

In the extension path of the positioning unit, the No. 1 conductive sheet 40 is contacted with the No. 2 conductive sheet 41 to complete the electrical connection, which can provide power for the laser module 30. The two positioning units extending from each limiting plate 8 can form two positioning harnesses in opposite directions on the side of the floor tile, which can complete auxiliary positioning for the subsequently laid floor tiles. At the same time, the positioning harness is established based on the measuring frame, so there is no need to repeatedly adjust the position of the positioning harness, which greatly reduces the difficulty of debugging and is conducive to construction.

[0026] Embodiment 3: Based on the positioning unit provided in Embodiment 1, this embodiment provides a further technical solution of the positioning unit.

[0027] like Fig.11 , Fig.12 and Fig.13 As shown, each positioning unit includes: The mounting seat 26 is arranged on the side wall of the slide plate 17 of the moving part and slides and extends into the moving area 16. A mounting cavity 27 is provided at the front end of the mounting seat 26. A positioning sleeve 28 is installed in the mounting cavity 27 by screwing. Specifically, an internal thread is provided on the inner wall of the mounting cavity 27, an external thread is provided on the outer wall of the positioning sleeve 28, and an operating ring is fixedly sleeved on the front end of the positioning sleeve 28; The annular capsule 29 is integrally arranged on the inner wall of the positioning sleeve 28. The laser module 30 is wrapped in the annular capsule 29. A receiving area 31 is reserved between the annular capsule 29 and the positioning sleeve 28. Intercommunication openings 32 are provided in a circular array on the side walls around the positioning sleeve 28. The annular capsule 29 is made of a flexible material such as rubber. like Fig.14 As shown, each positioning unit also includes: Two push chambers 33 are symmetrically arranged on both sides of the mounting seat 26. Each push chamber 33 is provided with a replenishing port. A certain amount of medium is injected into the push chamber 33. The medium is specifically a gas medium. Two sealing plates 34 are symmetrically and slidably installed in two pushing chambers 33. A trigger rod 35 is installed on the back of each sealing plate 34, and the trigger rod 35 slides out of the pushing chamber 33 accordingly. A limit ring 36 is sleeved on the trigger rod 35, and an action spring 37 is installed between the limit ring 36 and the pushing chamber 33. The sealing plate 34 is pulled back by the action spring 37. A ball is rotatably installed at the front end of each trigger rod 35. Two open areas 38 are correspondingly provided at the bottom of the two pushing chambers 33, and each open area 38 is interconnected with the receiving area 31 through the interconnection opening 32; Inclined areas 39 are provided on both sides of the inner wall of the moving area 16, and the inclined areas 39 are provided in cooperation with the trigger rod 35, and the extrusion triggering operation of the trigger rod 35 is completed through the inclined areas 39; A No. 1 conductive sheet 40 is installed on one side of each slide plate 17, a power supply box is provided on the limit plate 8, the No. 1 conductive sheet 40 is connected to the power supply box to complete the power supply control, and a No. 2 conductive sheet 41 connected to the laser module 30 is installed on both sides of the inner wall of the adjustment cavity 15, and the power supply control of the laser module 30 is completed through the cooperation of the No. 1 conductive sheet 40 and the No. 2 conductive sheet 41; It is worth noting that: when protecting the laser module 30: under normal conditions, when the laser module 30 is hidden in the moving area 16, the trigger rod 35 is at the end of the inclined area 39, so that under the action of the action spring 37, the sealing plate 34 is reset to the top of the pushing chamber 33. Since the intercommunication port 32 and the open area 38 can communicate with each other, the gas medium in the annular bag 29 is partially guided into the pushing chamber 33, so that the medium in the annular bag 29 is reduced, and the flexibility of the annular bag 29 is improved, so that the laser module 30 wrapped therein can be flexibly protected to avoid being affected by the outside. The problem of damage caused by boundary impact is avoided, and the service life of the laser module 30 is extended. When performing positioning measurement, the mounting seat 26 is moved by the push of the slide plate 17, and the trigger rod 35 is moved under the guidance of the inclined area 39, and the action spring 37 is squeezed to push the sealing plate 34 to move in the pushing cavity 33, and the medium in the pushing cavity 33 is pushed into the annular bag sleeve 29, so that the annular bag sleeve 29 expands, and can stably squeeze and limit the laser module 30, which is beneficial to the subsequent positioning measurement operation. Such a design enables the laser module 30 to have a good protection effect.

[0028] The present invention provides a positioning and measuring device for floor tile laying construction, and the specific working principle is as follows: first, the number of telescopic rods 7 is freely assembled according to the paving requirements, so as to form positioning and measuring work for different sides of the floor tiles. For example, telescopic rods 7 and limiting plates 8 are installed around the positioning ring platform 1. First, the length of the telescopic rods 7 is adjusted or replaced according to the size of the floor tiles, and then the handle 9 is pulled to assemble the entire measuring frame on the floor tiles, so that the multiple limiting plates 8 on the measuring frame are correspondingly engaged in the mortar joints around the floor tiles to form a fixation, and then the floor tiles are horizontally controlled according to the horizontal detection unit 2 on the positioning ring platform 1, which is beneficial to the subsequent paving of the floor tiles. By providing a pulling member, the construction personnel rotate the handle 9 to control the extrusion ring 6 to move in the annular cavity 4, so that the positioning ring platform 1 generates an adsorption force, and at the same time, the moving parts of the multiple limiting plates 8 can be controlled to drive the two positioning units hidden on each limiting plate 8 to extend, and the two positioning units on a single limiting plate 8 can complete the single-side of the floor tile. Positioning work, subsequent construction personnel can complete the paving work of adjacent floor tiles according to the positioning harness provided by the positioning unit, so that positioning harnesses are formed on the side walls around the floor tiles, which is beneficial to the auxiliary paving operation of adjacent floor tiles and optimizes the paving process. There is no need to use methods such as laying out lines to complete the paving assistance, and at the same time avoids the problem that traditional spirit levels need to be repeatedly debugged. The positioning and measuring device completes the paving positioning and measurement operations of floor tiles through the cooperation of a measuring frame and multiple positioning units. There is no need for repeated debugging, and the operation is convenient and the installation is flexible. It can be quickly transferred to different floor tiles to complete the subsequent auxiliary measurement work of floor tile paving, which improves construction efficiency and avoids the problem of repeated debugging and measurement. At the same time, the positioning unit takes into account the protection function of the laser module 30, and can protect the laser module 30 to avoid damage caused by external impact and affect the use. Moreover, a single positioning unit does not need to be controlled separately. Relying on the synchronous control with the positioning ring 1, the control difficulty is greatly reduced, making the overall operation more convenient.
