Description

Positioning inspection device for embedded foundation bolts

Technical Field

The utility model relates to a pre-buried rag bolt's location verifying attachment belongs to bolt detection technical field.

Background

Rag bolt all need do the acceptance after the installation finishes, does not have unified inspection tool at present, can only accept according to technical staff's experience, and the acceptance standard differs, and rag bolt does not have the symmetry installation often appears, causes the atress uneven, influences subsequent support fixed life.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art exists not enough, provides a location verifying attachment of pre-buried rag bolt, can inspect rag bolt fast, has unified the inspection standard, has improved rag bolt's support fixed life.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a location verifying attachment of pre-buried rag bolt, includes the body, the body is platelike structure, the middle part of body is provided with central through-hole, with central through-hole is the benchmark, and the cross radiates and is provided with central benchmark, four on the side of body the line between the central benchmark divide into four regions with the body, and every regional middle part all is provided with the benchmark hole, four the benchmark hole centre of a circle equals with the distance between central through-hole center and the central benchmark.

The central reference is a triangular opening, and one corner of the triangular opening is positioned on the cross radiation line of the central through hole.

The central reference is circular or square.

The body is of a square or round plate-shaped structure.

Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses a central benchmark and benchmark hole match with the toe board that corresponds and correspond, can the accurate position of confirming rag bolt, can not only the accurate atress that examines rag bolt distributes, through leading location moreover, can also avoid because of the loss of demolising unqualified rag bolt and causing, have improved the installation effectiveness.

Drawings

The present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1 is a body, 2 is a central through hole, 3 is a central reference and 4 is a reference hole.

Detailed Description

As shown in fig. 1, the utility model relates to a location verifying attachment of pre-buried rag bolt, including body 1, body 1 is platelike structure, the middle part of body 1 is provided with central through-hole 2, with central through-hole 2 is the benchmark, and the cross radiates and is provided with central benchmark 3, four on the side of body 1 line between the central benchmark 3 divide into four regions with body 1, and every regional middle part all is provided with benchmark hole 4, four the distance homogeneous phase between 4 centre of a circle of benchmark hole and central through-hole 2 centers and the central benchmark 3 equals.

The central reference 3 is a triangular opening, and one corner of the triangular opening is positioned on the cross radiation line of the central through hole 2.

The central reference 3 is circular or square.

The body 1 is a square or round plate-shaped structure.

In the testing process, utilize the total powerstation to beat the central line on four edges of toe board to pop out the solid line with the ink marker on the toe board, will the utility model discloses a four 3 alignment four solid lines of center benchmark, then can match four rag bolts on corresponding the toe board with four datum holes 4, if four rag bolts can match can correspond with four datum holes 4, then explain rag bolt's installation is qualified.

In order to reduce because of the unqualified losses such as doing over again that cause of rag bolt installation, can with the utility model discloses leading the application specifically is exactly before installation rag bolt, can utilize the total powerstation to confirm the central line of toe board, then will the utility model discloses the central line of corresponding alignment toe board, then make the sign on four reference hole 4's position, as long as during the construction install rag bolt in the position that this sign corresponds can make rag bolt's mounted position meet the requirements.

The present invention will be further described with reference to the following detailed description.

The template as shown (2mm steel plate) is made according to the size of the toe board, and the middle points of four sides are marked on the plate (cut by numerical control, and the error is controlled within 1 mm). And (4) according to the known coordinate points, using a total station to punch out a center line, and using an ink fountain to pop up the center line on the column. And sleeving the manufactured steel plate into the foundation bolt, moving the steel plate to enable the center points of the four sides of the steel plate to be superposed with ink lines popped up on the column, spraying a small amount of paint at the four corners of the steel plate by using the paint without moving the steel plate, and keeping the position marks on the column. And if the bolt deviation is large, marking the actual position of the bolt on the template, and reaming the column foot plate according to the mark. The method can effectively reduce errors caused by early construction and ensure the engineering quality.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
