Description

Technical Field

[0001] The utility model belongs to the technical field of building measurement, in particular to a simple verticality measuring tool for building templates. Background Art

[0002] The verticality of building formwork is the basic requirement to ensure the verticality of concrete components, which is crucial to the quality and safety of buildings. Traditional wall column formwork verticality detection technologies include plumb line construction methods and laser marking instruments. The plumb line construction method is to climb to the top of the wall after the wall formwork is supported, fix the plumb line to the steel pipe or screw joint at the top of the wall, and then lower the plumb line to 20cm from the bottom of the formwork. Measure the data of the upper and lower ends of the formwork by holding the plumb line until it stops, and finally compare the data to get the deviation value.

[0003] The existing measuring tools used in the hanging plumb line method are mostly composed of a workpiece that can retract and extend a measuring rope and a plumb line with a measuring rope. As mentioned above, during use, it is necessary to manually climb to the top of the wall to fix the measuring tool on the steel pipe or screw joint at the top of the wall, which increases the labor intensity of the measuring personnel, reduces the measuring efficiency, and is easy to get injured during the climbing process, and the safety factor of the measuring process is low.

[0004] For example, a Chinese invention patent with an authorization announcement date of 2024.03.22 and an authorization announcement number of CN114440847B discloses a verticality measuring tool for a construction formwork, comprising a right-angle connecting plate, a first adjustment groove and a first limit rod, wherein one side of the bottom of the right-angle connecting plate is fixedly connected to the first adjustment groove, the inside of the first adjustment groove is fixedly connected to the first limit rod, the surface of the first limit rod is nestedly connected to the first ring, the front of the first ring is fixedly connected to a movable pressure plate, the other side of the movable pressure plate is fixedly connected to a limit spring, and one side of the movable pressure plate is fixedly connected to a positioning pressure plate.

[0005] The above-mentioned prior art improves work efficiency, but the measuring tool is large in size and is clamped on the top of the construction formwork to be measured. Therefore, it is only suitable for measuring the verticality of the topmost formwork, but cannot measure whether the verticality of other positions of the completed multi-layer formwork is qualified.

[0006] Therefore, how to effectively solve the problem that the measuring tool is only suitable for measuring the verticality of the topmost formwork, and cannot measure whether the verticality of other positions of the completed multi-layer formwork is qualified is a technical problem that needs to be solved urgently. Utility Model Content

[0007] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a simple verticality measuring tool for building formwork, which solves the problem that the measuring tool is only suitable for measuring the verticality of the topmost formwork and cannot measure whether the verticality of other positions of the built multi-layer formwork is qualified.

[0008] The technical solution of this application is as follows:

[0009] A simple verticality measuring tool for building formwork, including a vertically telescopic unit with adjustable length. The top of the vertically telescopic unit is inserted and matched with the steel pipe of the formwork back rib through a horizontal insertion unit. The telescopic end of the vertically telescopic unit is connected with a winding unit for winding and unwinding a plumb bob unit. The measuring line of the plumb bob unit is slidably matched with the vertically telescopic unit and the horizontal insertion unit through corresponding guide wheels respectively. By inserting the measuring tool outside the formwork through the horizontal insertion unit, it is simple to manufacture, convenient for installation, disassembly and use, and can measure the verticality of the formwork at any position; by adjusting the vertically telescopic unit, the measurer can make adaptive adjustment according to the height of the building formwork, without the need for the measurer to climb onto the formwork and insert the line board between two steel pipes, improving the measuring efficiency, reducing the labor intensity of the personnel and the risk during the measuring process.

[0010] Further, the vertically telescopic unit includes a rod one and a rod two which are inserted into each other. The rod one and the rod two are positioned by a positioning member. The rod one is inserted into the rod two, and the positional relationship between the rod one and the rod two is adjusted according to the required length, and then positioned by the positioning member.

[0011] Further, guide wheels are arranged on the side surface of the rod one and / or the rod two to facilitate the lifting and lowering of the plumb bob.

[0012] Further, the horizontal insertion unit includes an insertion rod one arranged at the top of the rod one. One end of the insertion rod one is inserted between the steel pipes. The other end of the insertion rod one is provided with a guide wheel. The measuring line of the plumb bob is wound around the guide wheel. One end of the insertion rod one is inserted into the steel pipe gap between the upper and lower adjacent steel pipes, and thus the fixation of the insertion rod one and the whole measuring tool can be realized.

[0013] Further, the horizontal insertion unit includes an insertion rod two arranged at the bottom of the rod two. The end of the insertion rod two (42) is inserted and matched with the steel pipe (6) to maintain the stability of the measuring tool.

[0014] Further, the length of the insertion rod two is less than that of the insertion rod one to prevent the insertion rod two from affecting the plumb bob from hanging down.

[0015] Further, the insertion rod two is perpendicular to the rod two, and the insertion rod one is perpendicular to the rod one.

[0016] Further, the winding unit includes a line reel connected to the rod two. The line reel is rotatably connected with a winding roller. The end of the measuring line is connected to the winding roller and wound around a plurality of the guide wheels in sequence. A turning handle is connected to the winding roller, and the winding roller is limited by a limiting member.

[0017] Furthermore, the limiting member includes a screw rod, and the screw rod sequentially passes through a clearance slot on the rotating handle and a bolt hole on the wire drum for limiting.

[0018] Furthermore, a threading tube for the measuring line to pass through is provided on the side of the second rod, and the threading tube limits the measuring line so that the measuring line is close to the second rod to avoid a messy wire bundle.

[0019] The specific beneficial effects of the utility model include:

[0020] 1. The measuring tool is plugged into the outside of the template through the horizontal plug-in unit. It is simple to make, easy to install, disassemble and use, and can measure the verticality of the template at any position;

[0021] 2. By adjusting the vertical telescopic unit, the surveyors can make adaptive adjustments according to the height of the building formwork. There is no need for the surveyors to climb up the formwork to insert the wire plate between the two steel pipes, which improves the measurement efficiency and reduces the labor intensity and risk of the measurement process.

[0022] 3. Through the coordinated use of the guide wheel, the winding unit and the limiter, the height of the line sinker can be adjusted by hand. Compared with the existing manual line-releasing method, the line-releasing speed of the utility model is faster and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
