Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a simple acceptance tool for the verticality of a wall column template. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In construction, the verticality of wall and stud formwork is crucial to the stability and quality of building structures. Traditional methods for inspecting the verticality of wall and stud formwork often rely on manual measurement using plumb lines or equipment such as total stations. However, these methods have numerous drawbacks.

[0004] When using a plumb line for manual measurement, the operation is cumbersome and greatly affected by human factors, and the measurement accuracy is difficult to guarantee. Moreover, the plumb line bracket hung on the template is easily affected by external interference, resulting in inaccurate measurement results.

[0005] Although total stations have high accuracy, they are expensive and complex to operate, requiring professional personnel to operate them, which increases construction costs and time costs. In addition, the use of total stations on construction sites is often limited by site conditions and the construction environment, making it difficult to quickly and efficiently complete the verticality acceptance of a large number of wall column formwork.

[0006] In addition, traditional acceptance tools have low efficiency in data collection and processing during use, making it difficult to provide real-time feedback on measurement results. This is not conducive to timely discovery and correction of problems, which may lead to construction delays and quality risks.

[0007] In summary, in order to improve the efficiency, accuracy and convenience of the verticality acceptance of wall column formwork and reduce construction costs, it is particularly important to develop a simple, practical and efficient wall column formwork verticality acceptance tool.

[0023] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model discloses a simple acceptance tool for the verticality of a wall column formwork, comprising a vertical pole 1 with adjustable length, a horizontal pole 2 with adjustable length being rotatably provided at one end of the vertical pole 1 away from the ground, an angle locking mechanism 3 being provided between the vertical pole 1 and the horizontal pole 2, the angle locking mechanism 3 being used to lock the angles of the vertical pole 1 and the horizontal pole 2 when they are in a vertical state and when they are in a parallel state, a plumb line assembly 4 being provided on the horizontal pole 2 which can move and fix its position along the axis direction of the horizontal pole 2, and a level bubble 5 being provided on the vertical pole 1 for detecting the horizontality of the vertical pole 1.

[0025] The utility model uses the angle locking mechanism 3 to lock the angle when the vertical pole 1 and the cross bar 2 are in a vertical state, and then adjusts the position of the plumb line assembly 4 and the length of the vertical pole 1 and the cross bar 2 according to the template back ribs and the position of the tension screw that need to be avoided. After that, it is only necessary to push the cross bar 2 away from the end of the vertical pole 1 onto the reinforced template, hold the vertical pole 1 and observe that the horizontal bubble 5 is centered, and use a calibrated steel tape measure to measure the distance between the bottom of the plumb line assembly 4 and the template, and compare it with the distance of the plumb line assembly 4 on the cross bar 2. The verticality deviation of the template can be calculated according to the effective measurement height to determine whether the verticality of the template is qualified. After the measurement is completed, the vertical pole 1 and the cross bar 2 can be quickly retracted and folded, and transferred to the next measurement point for use, thereby effectively improving the problems of inaccurate measurement and safety risks caused by the need to climb up to hang lines or construction interference during the quality acceptance of existing wall column templates.

[0026] In a specific implementation, scale grooves are provided on both the vertical pole 1 and the horizontal pole 2 to facilitate the user to judge the adjustment height of the vertical pole 1 and the horizontal pole 2 and the adjustment distance of the plumb line assembly 4 on the horizontal pole 2.

[0027] In one embodiment, the vertical pole 1 and the horizontal pole 2 both include a fixed pole and a telescopic pole having one end inserted into the fixed pole and movable along the axis of the fixed pole. Both the fixed pole and the telescopic pole are hollow tubes. A threaded locking screw is provided on the fixed pole, having one end inserted into the fixed pole and abutting against the telescopic pole. When in use, the locking screw is rotated to release the positioning of the telescopic pole by the locking screw. After pulling out the telescopic pole to adjust the length of the vertical pole 1 and the horizontal pole 2, the locking screw is rotated to lock the telescopic pole, thereby achieving quick adjustment of the length of the vertical pole 1 and the horizontal pole 2.

[0028] In one embodiment, a conical adjusting head 6 is provided on the fixed rod of the upright pole 1 at one end away from the telescopic rod.

[0029] This design utilizes the conical adjusting head 6 to contact the ground, which can not only support the vertical pole 1, but also facilitate the user to adjust the placement angle of the vertical pole 1 according to the observation situation of the horizontal bubble 5.

[0030] In one embodiment, the angle locking mechanism 3 includes two side plates 31 fixedly arranged on the telescopic rod of the vertical pole 1, and a rotating shaft 32 fixedly connected to the fixing rod of the cross bar 2 is rotatably arranged between the two side plates 31. An L-shaped plate 33 passing through the side plates 31 is provided on the fixing rod of the cross bar 2. The L-shaped plate 33 consists of a transverse section and a vertical section. The transverse section of the L-shaped plate 33 is connected to the fixing rod of the cross bar 2. A guide groove 34 is provided on the side plate 31 for the transverse section of the L-shaped plate 33 to rotate around the rotating shaft 32. The side plate 31 is located between the vertical section of the adjacent L-shaped plate 33 and the fixing rod of the cross bar 2. A limit screw 35 that can move toward and away from the side plate 31 is provided on the vertical section of the L-shaped plate 33. A limit slot 36 is provided on the side plate 31 for the limit screw 35 to be inserted when the vertical pole 1 and the cross bar 2 are in a vertical state and when the vertical pole 1 and the cross bar 2 are in a parallel state.

[0031] With this design, the angles of the vertical pole 1 and the horizontal pole 2 in different working states can be locked by changing the position of the limiting groove 36 into which the limiting screw 35 is inserted.

[0032] In one embodiment, the plumb line assembly 4 includes a suspension rope 41 and a plumb line 42 provided at one end of the suspension rope 41. The other end of the suspension rope 41 is provided with a winding assembly for synchronously winding and releasing the suspension rope 41 when the vertical pole 1 is extended or retracted. The winding assembly includes a winding shaft 43 rotatably arranged in the fixed rod of the vertical pole 1. The telescopic rod of the vertical pole 1 is provided with a first bar-shaped hole adapted to the winding shaft 43. Two gears 44 are fixedly provided on the winding shaft 43. The winding assembly also includes a rack 45 fixedly provided on the telescopic rod of the vertical pole 1 and meshing with the gear 44. The end of the suspension rope 41 away from the plumb line 42 is located between the two gears 44 and is fixedly connected to the winding shaft 43.

[0033] The fixed rod and the telescopic rod of the cross bar 2 are both provided with a second strip hole for the hanging rope 41 to pass through from under the cross bar 2 when the cross bar 2 is perpendicular to the vertical pole 1. The plumb line assembly 4 also includes a position adjustment assembly detachably arranged on the cross bar 2 for adjusting the position of the hanging rope 41 passing through from under the cross bar 2. The position adjustment assembly includes a U-shaped rubber strip 46 sleeved on the cross bar 2 and a tightening screw 47 for the U-shaped rubber strip 46 to clamp the cross bar 2. The hanging rope 41 contacts the side of the U-shaped rubber strip 46 away from the vertical pole 1.

[0034] With this design, the telescopic rod of the vertical pole 1 will drive the gear 44 to rotate through the up and down movement of the rack 45 during the telescopic process, so that the reel 43 can complete the retraction and release of the hanging rope 41. When the hanging rope 41 is released, the gravity of the plumb line 42 at the other end of the hanging rope 41 can drive the released hanging rope 41 to move until the hanging rope 41 is taut, so that the distance of the plumb line 42 from the ground will not exceed the user's measurable area due to excessive extension of the telescopic rod of the vertical pole 1, ensuring that the user can measure normally when the vertical pole 1 is at different lengths. By adjusting the position of the U-shaped rubber strip 46 clamped on the cross bar 2 before measurement, the horizontal position of the hanging rope 41 and the vertical section of the ground can be changed, so that it can be quickly adjusted according to the obstruction position on the building template to avoid the obstruction on the building template affecting the measurement accuracy.

[0035] In the specific implementation, two limit plates are rotatably provided on the winding shaft 43, and both limit plates are located between the two gears 44. The limit plates are used to limit the winding position of the sling 41 on the winding shaft 43, which can effectively avoid the problem of the sling 41 being entangled on the gear 44 when winding. By providing a fixed pulley on the U-shaped rubber strip 46 that is inserted into the cross bar 2, the fixed pulley is used to contact the sling 41 to reduce the friction resistance of the sling 41 when winding.
