Description

Technical Field

[0001] The utility model belongs to the technical field of steel truss settlement monitoring, and in particular relates to a steel truss settlement monitoring device for shallow silo roof construction. Background Art

[0002] Before and during the pouring of concrete for the silo roof, it is necessary to observe the settlement of the steel truss formwork system. If abnormal settlement occurs, timely measures can be taken to prevent safety accidents.

[0003] At present, the settlement monitoring of steel truss formwork systems is mostly carried out manually. Specifically, a plumb line is first tied to the upper chord beam of the steel truss, about 1m above the ground, and then a 1.5m long steel pipe is set up next to the plumb line and driven 0.4m into the ground. Then, a 200mm long scale paper is pasted on the outer wall of the steel pipe as an observation basis. During the observation, a surveyor uses a square ruler (large triangle) to align the tip of the plumb line on one side and the scale paper on the steel pipe on the other side to read the reading. Another surveyor takes notes. After many observations, the difference between each reading is calculated as the settlement value, which is used to monitor the settlement of the steel truss formwork system. The monitoring process is cumbersome and requires at least two surveyors to cooperate with each other to achieve the purpose, which consumes manpower and increases labor costs.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0027] Embodiment: This embodiment aims to provide a steel truss settlement monitoring device for shallow silo roof construction, the main function of which is to effectively reduce manpower consumption and save labor costs.

[0028] Reference Figure 1 , Figure 2 and Figure 3 , including: a base 1, a sleeve 2, a plumb line and a slip ring 7, wherein the base 1 and the sleeve 2 are both made of plastic to reduce weight and facilitate carrying by staff, the base 1 is horizontally placed on the bottom of the shallow round warehouse, and the lower surface of the base 1 is provided with an annular groove 9 to reduce the contact area between the base 1 and the bottom of the shallow round warehouse, so as to prevent the base 1 from being affected by particles or protrusions on the ground at the bottom of the warehouse. The sleeve 2 is vertically fixed in the middle of the upper surface of the base 1, and two strip holes 3 are axially provided on the side of the sleeve 2, and the hole edge of the strip hole 3 is provided with scale lines 4 along its length direction, and the minimum scale and the maximum scale of the scale line 4 are respectively aligned with the two ends of the strip hole 3; a wire ring 10 is provided in the center of the top tube mouth of the sleeve 2 so that the lifting rope 6 passes through the wire ring 10, and the wire ring 10 is connected to the inner tube wall of the sleeve 2 through a horizontal positioning column 11, and a plurality of positioning columns 11 are evenly distributed along the circumferential direction of the wire ring 10.

[0029] Reference Figure 1 , Figure 2 and Figure 4 The line sinker includes: a sinker block 5 and a lifting rope 6. The sinker block 5 is conical and is slidably arranged inside the sleeve 2. The tip of the sinker block 5 faces downward and is coaxially arranged with the sleeve 2. The lower end of the lifting rope 6 is fixed to the top center of the sinker block 5. The sinker block 5 always slides along the axial direction of the sleeve 2 by the traction of the lifting rope 6. The upper end of the lifting rope 6 passes through the wire ring 10 and extends to the top of the sleeve 2 to be tied to the beam body of the steel truss, and the lifting rope 6 is coaxially arranged with the sleeve 2.

[0030] Reference Figure 1 , Figure 4 and Figure 5 The slip ring 7 is sleeved on the outside of the sleeve 2, and the inner ring of the slip ring 7 is in contact with the outer wall of the sleeve 2. The slip ring 7 and the sinker 5 are connected by a connecting rod 8 to make the slip ring 7 and the sinker 5 move synchronously. The connecting rod 8 passes through the strip hole 3. If the steel truss is lifted or lowered, the sinker 5 will inevitably slide down in the sleeve 2, and the slip ring 7 will move down synchronously with the sinker 5. Then, by observing the scale line 4 corresponding to the slip ring 7, the moving distance of the sinker 5 can be understood. The moving distance of this section of the slip ring 7 is the settlement value of the steel truss.

[0031] In this embodiment, refer to Figure 6 The number of monitoring devices is set to observe multiple points of the steel truss. Specifically, the observation points should be evenly arranged in two vertical directions, with a total of 6 points, so as to provide more comprehensive and accurate monitoring data.

[0032] During actual operation, the sinker 5 is first lifted to the top of the sleeve 2 through the lifting rope 6. At this time, the sinker 5 is restricted below the wire ring 10. Then, the corresponding hanging point on the steel truss beam continues to pull the sleeve 2 up through the lifting rope 6 to make the sleeve 2 leave the ground. The staff stabilizes the sleeve 2 to prevent it from shaking, and then puts the sleeve 2 back to the ground. This process is convenient and quick to calibrate the sleeve 2 and the lifting rope 6 to make the sleeve 2 and the lifting rope 6 coaxial, so that the sinker 5 can move more smoothly in the sleeve 2. Finally, a counterweight can be placed around the bottom of the sleeve 2 above the base 1 to ensure the stability of the sleeve 2. Each time the settlement of the steel truss is observed, the staff only needs to record the downward movement distance of the slip ring 7, and then calculate the difference with the last recorded data to obtain the settlement value of the steel truss. No excessive operation is required during the process, and the process is extremely simple.

[0033] The monitoring device provided in this embodiment only requires one surveyor to complete the collection and analysis of the settlement data of the steel truss formwork system. The operation is extremely simple, and can effectively reduce manpower consumption, greatly save labor costs, and provide great convenience for the pouring of concrete for the top plate of the shallow circular silo.

[0034] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
