Description

Technical Field

[0001] The utility model relates to the technical field of construction monitoring tools, and particularly relates to a portable verticality measuring tool for wall and column formworks. Background Technique

[0002] "Measurement and setting out, steel bars, formworks and concrete" are four important links in concrete construction. As shown, in the actual construction process, it is necessary to center around this guiding ideology, take measurement and setting out as the guide, formwork design as the focus, and the standard construction of steel bars and concrete as the guarantee, and adopt a series of technical measures and management measures according to the specific situation of the project to ensure meeting the quality requirements of concrete.

[0003] Among them, the verticality control of formworks is of utmost importance in formwork engineering. However, the current verticality measurement uses traditional tools, which are often time-consuming and laborious. The traditional method generally uses a plumb line. A measuring tape is used to take a point at each of the upper and lower ends of the plumb line, and the straight-line distances to the column formwork are measured respectively and compared to obtain the vertical deviation of the column formwork. However, since the plumb line needs to be hung at a high position, construction workers have to climb to a high place for fixation, which has certain potential safety hazards, and there are also defects such as large workload, low work efficiency and insufficient accuracy.

[0004] Therefore, how to design a vertical inspection ruler that is convenient to store, easy to use and not prone to damage the detection instrument is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] The utility model provides a portable verticality measuring tool for wall and column formworks, which solves the technical problem that the detection instrument of the vertical inspection ruler is exposed and easily damaged.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a portable verticality measuring tool for wall and column formworks includes: a first folding rod, a second folding rod, a locking assembly, a positioning member, a first detection rod and a second detection rod.

[0007] The first folding rod and the second folding rod are rotatably connected. One end of the first folding rod away from the second folding rod is provided with a first sliding groove, and one end of the second folding rod away from the first folding rod is provided with a second sliding groove. The locking assembly includes a driving rod and a driven rod. One end of the driving rod is hinged on the rod wall of the first folding rod close to the second folding rod. One end of the driven rod is hinged on the rod wall of the second folding rod close to the first folding rod, and the other end of the driven rod is hinged to the other end of the driving rod to lock the first folding rod and the second folding rod when the driving rod and the driven rod are collinear. There are two positioning members which are respectively connected to the first folding rod and the second folding rod. The first detection rod is slidably inserted into the first sliding groove, and a vertical detection disc is embedded on the rod wall of the first detection rod. The second detection rod is slidably inserted into the second sliding groove, and a spirit level is embedded on the rod wall of the second detection rod.

[0008] The beneficial effects of the present utility model are as follows: The structure of the traditional vertical detection ruler is improved. First, a four-bar linkage structure is formed by the first folding rod, the second folding rod, the driving rod and the driven rod. When the driving rod and the driven rod are collinear, the first detection rod and the second detection rod can be locked, which is convenient for the first detection rod to be unfolded or folded. Then, by sliding the first detection rod in the first sliding groove of the first folding rod and the second detection rod in the second sliding groove of the second folding rod, since the vertical detection disc is embedded on the rod wall of the first detection rod and the spirit level is embedded on the rod wall of the second detection rod, in the non-use state, the vertical detection disc and the spirit level can be inserted into the first sliding groove and the second sliding groove together with the first detection rod and the second detection rod, avoiding the detection instruments being directly exposed to the air, preventing the detection instruments from being knocked and scratched, and prolonging the service life of the detection instruments. In addition, by using two positioning members respectively connected to the first folding rod and the second folding rod, the first folding rod and the second folding rod can be more conveniently positioned on the wall, improving the measurement accuracy of the detection ruler.

[0009] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0010] Further, a receiving groove is provided on the rod walls of the driven rod close to the first folding rod and the second folding rod. The driving rod can be movably extended into the receiving groove.

[0011] The beneficial effect of adopting the above is that by extending the driving rod into the receiving groove of the driven rod, the collinearity between the driving rod and the driven rod can be better realized, and the dead point can be locked.

[0012] Further, the positioning member includes a connecting portion, a rotating shaft, a screw rod, and a tapered plate. The connecting portion includes two connecting plates. The two connecting plates are located on opposite sides of the first folding rod or the second folding rod, and a threaded hole is provided on one of the connecting plates. Fixed bumps are provided on both the first folding rod and the second folding rod, and through holes are provided on the bumps. The rotating shaft is rotatably connected in the through holes, and its two ends are respectively fixed to the two connecting plates. The screw rod is screwed into the threaded hole, and its screwed end can contact the first folding rod or the second folding rod. The large-area end of the tapered plate is fixed to the two connecting plates.

[0013] The beneficial effect of the above further improvement is: first, rotate the two connecting plates by using the rotating shaft, and then position the two connecting plates by using the screw rod, so that the positioning angle of the two positioning members can be changed, and the applicable range of the inspection ruler can be increased.

[0014] Further, it further includes two light-emitting rings, and the two light-emitting rings are respectively fixed on the vertical inspection disk and the spirit level.

[0015] The beneficial effect of the above further improvement is: by fixing the light-emitting rings on the vertical inspection disk and the spirit level, the observation brightness of the vertical inspection disk and the spirit level can be increased.

[0016] Further, a first limiting ring is sleeved on the insertion end of the first detection rod extending into the first sliding groove; a second limiting ring is sleeved on the insertion end of the second detection rod extending into the second sliding groove; a first blocking ring is penetrated through the inner groove wall of the first sliding groove near its notch; a second blocking ring is penetrated through the inner groove wall of the second sliding groove near its notch; the first limiting ring can contact the first blocking ring; the second limiting ring can contact the second blocking ring.

[0017] The beneficial effect of the above further improvement is: by using the first limiting ring to contact the first blocking ring, the first detection rod can be prevented from detaching from the first folding rod. Similarly, by using the second limiting ring to contact the second blocking ring, the second detection rod can be prevented from detaching from the second folding rod. Description of the Drawings
