Description

Technical Field

[0001] This utility model belongs to the technical field of engineering construction layout, and specifically relates to a layout positioning control point fixing and adjustment device. Background Technology

[0002] In engineering construction, setting out and positioning is a crucial step to ensure that buildings and structures are constructed according to design requirements. The accuracy of control points directly affects the overall construction quality and safety. Currently, commonly used control points are typically set up using wooden stakes, nails, or concrete piles. These traditional control points have the following shortcomings: First, their stability is poor, easily affected by factors such as construction machinery rolling, material stacking, and personnel movement, leading to displacement or damage. Second, traditional control points lack precise height adjustment capabilities, making it impossible to fine-tune the elevation and horizontal position, resulting in deviations in setting out and positioning. Third, some control points are difficult to maintain long-term during construction, requiring frequent re-measurement, which not only increases construction steps but also wastes manpower and resources, affecting construction efficiency.

[0003] Therefore, how to design a stringing positioning control point control device that is stable, accurate, widely applicable, and easy to operate and maintain has become an urgent technical problem to be solved. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wire laying positioning control point fixing and adjustment device.

[0005] The technical solution adopted by this utility model is a line-laying positioning control point fixing and adjustment device, including a square main frame formed by four rectangular tubes. A level bubble is embedded in the upper middle part of each rectangular tube. A guide plate is vertically arranged on the inner side of the main frame. A first strip-shaped guide groove is provided on the guide plate along the length direction. Cross-shaped horizontal bars are arranged inside the main frame. A second strip-shaped guide groove is provided on the horizontal bars along the length direction. The two ends of the horizontal bars are respectively fixed in the first strip-shaped guide grooves on both sides by fastening bolts. A control point bolt is fastened at the intersection of the two horizontal bars through the second strip-shaped guide groove. Through holes are provided vertically at the four corners of the main frame. A screw is installed in the through hole. The upper end of the screw is fastened to the main frame. The lower end of the screw is threadedly connected to a sleeve. The sleeve is pre-embedded in a stable stratum or structure.

[0006] Furthermore, a retaining ring is fixed to the upper part of the screw shaft, the lower side of the main frame abuts against the retaining ring, and the upper end of the screw is threadedly connected to a retaining nut abutting against the upper side of the main frame.

[0007] Furthermore, the rectangular tube is made of long strips of tubing with a length of 20cm, a width of 3cm, and a height of 1cm.

[0008] Furthermore, a groove is cut in the middle of the rectangular tube, and a level bubble is fixed in the groove.

[0009] Furthermore, the diameter of the screw is 2cm.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This device, through the connection between the main frame and the pre-embedded bolt sleeve, firmly fixes the control points in stable strata or structures, ensuring the long-term stability of the points during construction. The embedded level bubble not only assists in precise leveling but also allows for quick visual inspection to determine if the control points have shifted, improving construction safety and the reliability of layout. By setting adjustable crossbars, control point bolts, and level bubbles, fine adjustments to the coordinate position and elevation of the control points can be achieved, meeting the stringent requirements for control accuracy during construction.

[0012] 2. This device is suitable for various construction scenarios such as setting out positioning points, monitoring points, and measurement benchmarks. It can also be used under different geological conditions such as concrete surface layers, crushed stone layers, and earthwork surfaces. The control points can be stably preserved for a long time or temporarily and can withstand the environment of multi-stage construction interference, thus having wide applicability.

[0013] 3. The structure is reasonably designed, and the installation and adjustment process is simple. Construction personnel can quickly master the usage method, improve construction efficiency, and reduce labor intensity. Attached Figure Description

[0019] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a device for positioning and laying out control points according to this utility model.

[0020] like Figure 1 and Figure 2As shown, a line-laying positioning control point fixing and adjustment device includes a square main frame formed by four rectangular tubes 1. A level bubble 2 is embedded in the upper middle part of each rectangular tube 1. A guide plate 3 is vertically arranged on the inner side of the main frame. A first strip-shaped guide groove is provided on the guide plate 3 along its length. Cross-shaped horizontal bars 4 are arranged inside the main frame. A second strip-shaped guide groove is provided on the horizontal bars 4 along its length. The two ends of the horizontal bars 4 are respectively fixed in the first strip-shaped guide grooves on both sides by fastening bolts 5. A control point bolt 6 is fastened through the second strip-shaped guide groove at the cross intersection of the two horizontal bars 4. Through holes are provided vertically at the four corners of the main frame. A screw 7 is installed in the through holes. The upper end of the screw 7 is fastened to the main frame. The lower end of the screw is threadedly connected to a sleeve 8. The sleeve 8 is pre-embedded in a stable stratum or structure.

[0021] like Figure 3 and Figure 4 As shown, in this embodiment, the rectangular tube 1 consists of four long strips of tubes, each 20cm long, 3cm wide, and 1cm high. Grooves are cut in the middle of each rectangular tube 1, and the level bubble 2 is fixed in the groove. Finally, the four rectangular tubes 1 are welded together to form a square main frame.

[0022] The guide plate 3 is made of a 4mm thick steel plate with a length of 15cm and a width of 5cm, and is welded to the lower side of the main frame. A first strip-shaped guide groove is cut out in the middle along the length direction. The crossbar 4 is made of a steel plate with a length of 15cm and a width of 2cm. A second strip-shaped guide groove is chiseled out in the middle along the length direction. The two ends of the crossbar 4 are fixed to the first strip-shaped guide groove on both sides with fastening bolts 5. A control point bolt is set between the two crossbars 4 as the coordinate of the fixed point.

[0023] Vertical circular through holes are cut at the four corners of the main frame. Four 2cm diameter screws 7 are passed through the circular through holes. The lower part of the screws is threaded to a sleeve 8, which can adjust the height of the main frame. A retaining ring 9 is welded to the upper quarter of the screw 7. The lower side of the main frame rests on the retaining ring 9, and the upper end of the screw 7 is threaded to a retaining nut 10, which rests on the upper side of the main frame.

[0024] In use, the approximate location of the control point is determined by the instrument, the four sleeves 8 are embedded in the determined location and fixed firmly, the screw 7 is inserted into the sleeve 8, and the height of the screw 7 is adjusted according to the required elevation to obtain the required elevation, while ensuring that the level bubble 2 remains horizontal. Finally, the position of the control point is precisely controlled by adjusting the crossbar 4.

[0025] The main body of this control device is made of high-strength, corrosion-resistant materials, which can meet the requirements of long-term or multi-stage construction, reducing the costs caused by frequent setting and maintenance of control points. Furthermore, its high reusability effectively reduces the need for repeated surveying and material waste caused by damage to traditional control points, thus lowering construction costs.
