The positioner of steel construction still includes a plurality of locating levers 3, and the quantity of locating lever 3 is three in this embodiment. Three locating levers 3 are along the circumference evenly distributed of link, and is specific, every locating lever 3 respectively with the tip welding of support 2. One side of each locating rod 3, which is far away from the connecting frame, is connected with a locating part in a sliding way. The both sides of the one end that the locating lever 3 kept away from the link are equipped with spout 4, and location portion passes through spout 4 and locating lever 3 sliding fit.
Location portion includes connecting plate 5, setting element 9 and first bolt 6, and connecting plate 5 upper end is through spout 4 and locating lever 3 sliding fit. The locating piece 9 comprises a cylindrical section and a conical section, the cylindrical section penetrates through the connecting plate 5 and is welded with the connecting plate 5, one end, far away from the connecting plate 5, of the locating piece is the conical section, and the conical section is used for being tightly abutted to the inner lining plate. The top end of the connecting plate 5 is provided with a threaded through hole, and the first bolt 6 is in threaded fit with the threaded through hole. After the location portion that slides arrived the assigned position, because first bolt 6 and screw thread through-hole screw-thread fit, twist and move first bolt 6, can make first bolt 6 support tightly with locating lever 3 to avoid location portion to slide along locating lever 3 when measuring. The tip of locating lever 3 is equipped with support piece, and 3 terminal surfaces of locating lever are equipped with the scale.
The specific implementation process is as follows: as shown in fig. 2, the connecting bracket is fixed to the end of the steel structure, and then the support is placed on the end of the steel column 15. Then, the positioning part is slid along the positioning rod 3, the end part of the conical section of the positioning part 9 of the positioning part is abutted against the inner lining plate 16, the distance between the positioning part and the connecting rod 12 is adjusted, when the lengths of the three positioning parts from the connecting frame are the same, the circle center of the steel upright post 15 and the axis of the connecting rod 12 are collinear, and the position of the prism 13 can be determined through a total station. The positioning parts 9 of the three positioning parts can also play a role in limiting when abutting against the lining plate 16, namely, the positioning device can be ensured not to fall off from the steel upright post 15.
The lower end of the connecting rod 12 is fixedly connected with the middle of the connecting frame, so that when the circle center of the connecting frame is determined to coincide with the circle center of the steel upright post 15, the axis of the connecting rod 12 can be ensured to penetrate through the circle center of the steel upright post 15, and further, the line connecting the circle centers of the prism 13 and the steel upright post 15 is ensured to coincide with the axis of the connecting rod 12, and because the length of the connecting rod 12 is fixed, the distance between the prism 13 and the center of the connecting frame is fixed, the central position of a cylinder can be determined after the position of the prism 13 is measured, and the operation is. The steel structure generally includes an inner lining 16 at the top end of the steel pillar 15 in addition to the steel pillar 15, and the height of the inner lining 16 is generally higher than that of the steel pillar 15. Therefore, support piece has been set up at the tip of locating lever 3 in this application, and support piece is used for supporting at steel stand 15 up end, and support piece and location portion cooperation also can press from both sides tight inside lining board 16, and then can fix positioner on the steel construction, and positioner drops when avoiding fixing a position the steel construction (especially the steel construction that the slope set up advances line location).
Example two
As shown in fig. 3, the difference between this embodiment and the first embodiment is that the number of the positioning rods 3 is four, on one hand, the number of the positioning rods 3 is small, and the operation is convenient, and on the other hand, the four positioning rods 3 can position not only the steel column 15 with a circular cross section, but also the steel column 15 with an oval cross section, and the application range is wider. When the steel upright post 15 with the oval cross section is positioned, the lengths of the positioning parts of the two positioning rods 3 on the same straight line from the connecting frame are ensured to be the same.
As shown in fig. 4 and 5, in the present embodiment, the support member is a variable-length support member. Specifically, support piece includes connecting block 7 and second bolt 8, and the screw hole has been seted up to connecting block 7 lower extreme, and second bolt 8 and screw hole screw-thread fit. The bottom end of the positioning rod 3 is provided with a sliding groove 11, and the connecting block 7 is in sliding fit with the positioning rod 3 through the sliding groove 11. Support piece and 3 sliding fit of locating lever can adjust the distance of support piece apart from the link as required to be applicable to the not steel construction of equidimension.
When the positioning is carried out, the distance from the free end of the second bolt 8 to the connecting block 7 can be adjusted by screwing the second bolt 8, and then the height of the whole supporting piece is adjusted. The screw thread has self-locking function, and through the screw-thread fit of second bolt 8 with the screw hole, can adjust support piece to arbitrary length, the adaptability is wider. In this embodiment, the length of the supporting member can be adjusted as required, so as to change the height of the positioning rod 3 from the end surface of the steel upright post 15, and the operation is more convenient when the lining plate 16 of the steel upright post 15 has different heights.
The end part of the positioning rod 3, which is far away from the connecting frame, is provided with a limiting plate 10, and the limiting plate 10 is fixedly connected with the positioning rod 3 through a screw 14. The limiting plate 10 is used for limiting, and the positioning part is prevented from sliding out of the positioning rod 3.
EXAMPLE III
As shown in fig. 6, the difference between the present embodiment and the second embodiment is that the present embodiment further includes a connecting sleeve 17, one end of the connecting sleeve 17 is welded to the middle of the connecting frame, one end of the connecting rod 12 far away from the prism 13 extends into the connecting sleeve, and the connecting rod 12 slides along the connecting sleeve. Connecting rod 12 slides along the connecting sleeve, can prolong connecting rod 12 apart from the length of link, avoids when the inclination of steel construction is too big, thereby the steel construction can block the measurement to prism 13 and produce adverse effect to the location of steel construction. When the connecting rod 12 does not need to slide, the connecting sleeve and the connecting rod 12 can be limited by friction force between the connecting sleeve and the connecting rod, and a bolt can be connected to the side part of the connecting sleeve in a threaded mode.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
