Description

Technical Field

[0001] The utility model relates to a bolt pre-embedded dot positioning tool, specifically a bolt pre-embedded dot positioning tool for cantilevered I-beam bolts at corners, which is mainly used for dot marking and positioning of pre-embedded bolts of cantilevered I-beam bolts at corners, and belongs to the technical field of pre-embedded positioning in construction. Background Art

[0002] Generally speaking, external scaffolding technology for construction projects is constantly evolving. Compared to traditional embedded cantilever scaffolding, pull-up cantilever scaffolding has seen widespread adoption in recent years due to its advantages, including structural non-destruction, recyclable I-beams, rapid construction, material savings, and no need for post-installation waterproofing. However, due to uneven formwork tops and the presence of primary and secondary keels on construction sites, measurement errors can lead to poor positioning results, low efficiency, and a long installation time. Currently, cantilever scaffolding anchor plates are difficult to position on the main structure and prone to deviation. Controlling the distance between adjacent bolts and the horizontal elevation of the bolts at corners is particularly challenging, as the positioning dimensions of different cantilever scaffolding anchor plates vary. Workers must use a tape measure and level to drill each hole individually, resulting in a large workload, low efficiency, and a high risk of errors.

[0003] The positioning of traditional cantilever scaffolding anchor plates mainly adopts tape measure and level ruler. This positioning method makes it difficult to control the distance and elevation between the two corner bolts. The main problems at this stage are inaccurate positioning and substandard levelness, which can easily cause the cantilever I-beam to be unable to install or uneven and misplaced. In addition, the construction efficiency is low, time-consuming and labor-intensive, and there may even be safety hazards.

[0004] Although a tool for positioning cantilever I-beam bolts at corners has been developed in the prior art, the tool cannot perform dot positioning marks according to the inconsistent positioning sizes of different cantilever scaffolding anchor plates or I-beam anchor plates during use. The tool can only perform dot positioning for one or two types of structures and cannot perform positioning work for cantilever scaffolding anchor plates or I-beam anchor plates of various types and sizes according to actual needs. In short, it is often very inconvenient.

[0005] Therefore, the key to solving the above technical problems is to develop a simple and practical tool for pre-embedded positioning of cantilevered I-beam bolts at corners. Summary of the Invention

[0078] In summary, the more specific implementation methods of the present invention are:

[0079] Before using the above-mentioned design structure of a pre-embedded positioning tool for cantilevered I-beam bolts at corners, the already manufactured positioning tool of the design structure needs to be installed as a spare according to actual construction needs.

[0080] Before installation, the operator needs to prepare in advance the ink or paint used in conjunction with the present invention, which is mainly used for application on the dot marking part 242 of the adjustable positioning dot marking part 24 of the present invention during installation, so as to achieve clearer and more accurate marking of the fixed point, making it convenient for subsequent punching workers to accurately and quickly find the corresponding bolt embedded punching position, thereby achieving accurate positioning of the bolt position.

[0081] During installation, according to the needs of actual construction conditions, the operator pre-installs the adjustable connecting piece 22 on the mounting frame 21, and puts the adjustable connecting piece 22 on both ends of the mounting frame 21, and adjusts the adjustable connecting pieces 22 at both ends of the mounting frame 21 to the appropriate position by looking at the scale lines set on the top end face of the mounting frame 21, and then uses the limiting tightening piece 23 to limit and fix it. Subsequently, an adjustable positioning dot marking piece 24 is put on the adjustable connecting piece 22. At the same time, after adjusting the adjustable positioning dot marking piece 24 to the appropriate position, the end portions of the mounting hole 221 are fastened by the anti-slip locking piece 25. After the fastening is completed, the installation work of the utility model is completed, and it can be used after the installation is completed.

[0082] During use, the operator first measures and lays out the lines on site to determine the specific installation position of the embedded screw or bolt; then, the operator holds the hand-held part of the mounting frame 21 so that the distance between the dot marking part 242 on the adjustable positioning dot marking member 24 meets the distance between the bolt or screw installation position, and then, the operator controls whether the utility model is in a horizontal position through the level meter on the calibration device 1 and adjusts the positioning position; then, the operator holds the mounting frame 21 tightly and controls the dot marking part 242 on the adjustable positioning dot marking member 24 to contact the wall or template corresponding to the corner part 3 that needs to be marked in advance On the wall or template, a clear marking point mark is left by controlling a certain force or by applying colored ink or paint on the dot marking part 242 in advance, thereby forming a bolt pre-embedded positioning mark 4. Finally, the operator uses an electric drill to drill holes in the template or wall in sequence according to the bolt pre-embedded positioning mark 4, thereby completing the positioning work of the embedded bolts or screws. At the same time, the corner cantilever I-beam 6 is accurately installed at the corresponding opening position of the corner part 3 with a screw or bolt, thereby ensuring the accuracy of the installation, effectively ensuring the installation quality, and can also be used to achieve the installation of other embedded parts.

[0083] Finally, as time goes by, after the above positioning work is completed, the operator only needs to clean and repair the various components of the utility model, and then move them to the designated tool storage warehouse for storage by manual or corresponding handling equipment for preparation for the next cycle of use.

[0084] The utility model is easy to operate and provides installation accuracy for screws and embedded bolts. The outer side of the template of the embedded bolts or screws is measured to measure the size of the floor to be lowered. When using, it is only necessary to use this tool and the embedded point of the positioning bolt to form a bolt embedded positioning mark 4 by using the tool, and then use a handheld electric tool to drill holes in the bolt embedded positioning mark 4 to embed the bolt.

[0085] Finally, it should be noted that the above detailed description of the specific implementation of the present invention is given in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation. Various changes can be made thereto within the knowledge of ordinary technicians in this field.
