Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an adjustable-size laser caliper. Background Art

[0002] The gauge rod is usually erected at the corner or partition wall of a building. When setting up the gauge rod, first drive a large wooden stake into the foundation, use a level to measure the elevation position of ±0.000, and draw a horizontal line as a mark. Then align the ±0.000 on the gauge rod with the ±0.000 on the wooden stake, and use a large nail to vertically nail the gauge rod to the large wooden stake. Add two diagonal braces to support the rod body. After the gauge rod is nailed, it should be checked with a level and the verticality of the gauge rod should be corrected with a plumb bob.

[0003] For ease of construction, when using internal scaffolding for bricklaying, the bricklaying gauge rod should be erected on the outside of the wall; if using external scaffolding, the bricklaying gauge rod should be erected on the inside of the wall; if using a frame or reinforced concrete inter-column wall, the number of bricklaying layers can be drawn directly on the component without erecting a bricklaying gauge rod.

[0004] In general, during building construction, the suspended plumb bob method is commonly used to project the axis line layer by layer upwards. The procedure is as follows: a heavy plumb bob is suspended from the edge of the floor slab or column top. When the tip of the plumb bob aligns with the positioning axis line on the foundation, the position of the line at the edge of the floor slab or column top is the endpoint of the floor axis line. A short line is drawn as a marker. The other endpoint is then projected in the same way, and the line connecting the two ends is the positioning axis line. Other axes are projected in the same way, and the spacing between each axis line is checked with a steel ruler before construction continues, transferring the axis lines layer by layer from bottom to top. To reduce the accumulation of errors, after every two or three layers, a theodolite is used to project the axis lines from the ground onto the floor slab or column to check the accuracy of the axis line positions transferred layer by layer. Therefore, an adjustable-size laser caliper is proposed to solve the above problem. Utility Model Content

[0019] The second level is positioned horizontally at the top of the base.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the height of the scale tube can be quickly adjusted by overlapping or separating the card block and the card slot.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1-3This utility model provides an embodiment of an adjustable laser picometer, comprising a base 1, a sleeve 2 fixedly connected to the top of the base 1, a connecting tube 3 slidably connected to the inner wall of the sleeve 2, the sleeve 2 being hollow to allow the connecting tube 3 to move vertically along the inside of the sleeve 2, a limit mechanism provided on the inner wall of the connecting tube 3, and a guide tube 6 fixedly connected to the inner wall of the connecting tube 3, the guide tube 6 allowing the locking block 5 to slide along the inner wall of the connecting tube 3 and ensuring that the return spring 4 does not undergo large deformation, a locking groove 7 opened on the outer wall of the sleeve 2, the locking groove 7 having a horizontal opening and a vertical opening, the locking block 5 coinciding with the vertical opening allowing the locking block 5 to move along the vertical opening with the connecting tube 3, the locking block 5 coinciding with the horizontal opening preventing the locking block 5 from moving vertically with the connecting tube 3, and a scale tube 8 fixedly connected to the top of the connecting tube 3, the scale tube 8 having scale markings, allowing the upper... The lower moving block 9 allows the laser 11 to be positioned at the corresponding scale mark for measurement. The top of the scale tube 8 is fixedly connected to the top fixed cone 12, and the moving block 9 is slidably connected to the outer wall of the scale tube 8. The moving block 9 mainly connects the first level 10 and the laser 11, and the moving block 9 has friction with the scale tube 8, allowing the moving block 9 to stay at any position of the scale tube 8 at any time. The outer wall of the moving block 9 is provided with the first level 10, which can determine whether there is a deviation in the position of the scale tube 8 and the moving block 9. The side wall of the moving block 9 is provided with the laser 11, which can be used to perform subsequent measurements in poor lighting conditions and for long masonry sections. The top of the base 1 is provided with the second level 13, which can determine whether the base 1 is in a horizontal state. The inner wall of the base 1 is provided with an adjustment component.

[0031] The limiting mechanism includes a locking block 5, which is slidably connected to the inner wall of the connecting pipe 3. The connecting pipe 3 has a slot corresponding to the locking block 5, which allows the locking block 5 to move along the slot of the connecting pipe 3. The left end of the locking block 5 is elastically connected to the connecting pipe 3 through a reset spring 4.

[0032] Reference Figures 1-3 The adjustment assembly includes a threaded cone 14, which is threaded through and connected to the inner wall of the base 1. The base 1 has threads corresponding to the threaded cone 14. There are four sets of threaded cones 14, which are symmetrically distributed on the base 1. The left end of the locking block 5 is fixedly connected to one end of the return spring 4. When the locking block 5 moves to the left, it will compress the return spring 4. When resetting, the return spring 4 will use its reverse elastic force to reset the locking block 5. The other end of the return spring 4 is fixedly connected to the inner wall of the left end of the connecting pipe 3. The locking block 5 is slidably connected to the outer wall of the guide pipe 6. The locking block 5 is engaged with the inner wall of the slot 7. The second level 13 is horizontally distributed at the top of the base 1.

[0033] Working principle: First, when using the entire device to determine the position of the layer-by-layer axis, simply install the base 1 at the designated measurement location, ensuring that the base 1 is horizontal after installation. This can be determined by the second level 13. Depending on the height requirements, rotate the threaded cone 14 clockwise or counterclockwise. Adjust the height of the base 1 so that the threaded cone 14 moves downwards or upwards along the inner wall of the base 1, ensuring that the base 1 does not produce any height deviation at the four corners. When adjusting the height of the scale tube 8, simply move the locking block 5 to the left to separate the locking block 5 from the horizontal opening of the slot 7. At this time, the return spring 4 is compressed, allowing the locking block 5 to enter the vertical slot of the slot 7. Then, pull the locking block 5 upwards, carrying the connecting tube 3 and the scale tube 8. When the designated position is reached, simply move it to the right and use the elasticity of the return spring 4 to allow the locking block 5 to enter the horizontal opening of the slot 7, preventing it from moving up or down. If further adjustment is needed, simply repeat the above steps.

[0034] During normal use, the brick diagram needs to be arranged in advance, and the required scale table for each layer needs to be calculated. According to the calculation table, the moving block 9 moves upward, carrying the laser 11 upward, so that it stops at the designated position using its own friction. Then, the laser 11 is turned on to irradiate the bricks, which helps to prevent excessive errors in long-span masonry. In subsequent use, the moving block 9 can be moved to any position on the scale tube 8 according to the actual situation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
