Abstract
The utility model relates to an arc scale for reserved holes on a steel pipe. The arc scale comprises a scale plate and graduation lines, wherein the main body of the scale plate is arc-shaped; the internal diameter of the scale plate is consistent with the external diameter of a tested steel pipe; a positioning axis perpendicular to span is carved at a middle point of the arc length of the scale plate and is taken as scale zero; and scale lines are carved on the two sides of the scale zero outwards in sequence respectively. The arc scale has a simple structure and is convenient to operate; a through hole is positioned through relative size of the arc scale and an outer arc line of the tested steel pipe; the positioning line is used for positioning relative position of the arc scale and the tested steel pipe; and thus, the accuracy for positions of the reserved holes is guaranteed, time and labor are saved, accumulative deviation is avoided, smooth performance of a project is facilitated, the efficiency is increased, the manufacturing material can be readily obtained on the construction site, and the cost is saved. The arc scale can be widely applied to determining the positions of the reserved holes of the steel pipe during building construction.
Description
Technical field
The utility model relates to a kind of building operation and uses the measurement and positioning instrument.
Background technology
When the round steel pipe concrete superposed column was connected with the steel reinforced concrete beam, the vertical muscle of beam need run through steel pipe, so needed to reserve reserving hole on the steel pipe, with so that beam is indulged muscle passes.At present, confirm that on the steel pipe outer arc position of reserving hole is through arc length outside the tape measure steel pipe, demarcate the position of reserving hole then; Generally, steel pipe is to be that material is processed with the roll bending, and there is certain deviation in its radian; The tape measure location can to such an extent as to deviation appears in the position of determined reserving hole, make the vertical muscle of beam to run through smoothly the deviation accumulation; This will influence the progress of work, reduce work efficiency.
The utility model content
The purpose of the utility model provides a kind of steel pipe reserving hole and uses the arc chi, its objective is that will solve the position of steel pipe reserving hole on steel pipe exists deviation, is difficult for the location, causes the vertical muscle of beam can't run through the technical matters of steel pipe.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of steel pipe reserving hole is used the arc chi; Comprise chi plate and scale mark; The main body of said chi plate is an arc, and the internal diameter of chi plate is consistent with the external diameter of tested steel pipe, and the arc length mid point of chi plate is carved with the orientation axis perpendicular to chord length; And with orientation axis is 0 scale, and the both sides of 0 scale outwards are carved with dimension line respectively in proper order.
All there is one section straight-line segment that is parallel to chord length at the outer camber line of said chi plate main body and interior camber line two ends, and the two ends sideline is perpendicular to chord length.
The material of said chi plate is scale board, solid wood plate, rigid plastic sheet or cardboard.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model has overcome conventional tape measure and has located the shortcoming that there is deviation in reserving hole, has solved the technical matters of accurate positioning steel tube reserving hole position.
The utility model is simple in structure, makes easily, and manufacturing materials can be obtained on construction ground easily, practices thrift cost, can not cause waste.
The utility model is easy to operate; Orientation axis on it is located reserving hole in order to the relative position of location arc chi and steel pipe through the relative size of arc chi and the outer camber line of steel pipe, guarantees the accuracy of reserving hole position; Time saving and energy saving; Avoid Accumulated deviation, the assurance engineering is carried out smoothly, has improved work efficiency.The utility model can be widely used in confirming in the building construction process steel pipe reserving hole position.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the shape synoptic diagram of the utility model.
Fig. 2 is the working state schematic representation of the utility model.
Reference numeral: 1-chi plate, 2-dimension line, 3-orientation axis, the tested steel pipe of 4-, 5-reserving hole, 6-steel pipe axis.
Embodiment
Embodiment is referring to shown in Figure 1, and a kind of steel pipe reserving hole is used the arc chi, comprises chi plate 1 and scale mark 2; The main body of said chi plate 1 is an arc, and the internal diameter of chi plate 1 is consistent with the external diameter of tested steel pipe, and the arc length mid point of chi plate 1 is carved with the orientation axis 3 perpendicular to chord length; In order to confirming the relative position of arc chi and tested steel pipe 4, and be 0 scale with orientation axis 3, the both sides of 0 scale outwards are carved with dimension line 2 respectively in proper order; All there is one section straight-line segment that is parallel to chord length at the outer camber line of said chi plate main body and interior camber line two ends, and taking and placing are convenient to perpendicular to chord length in the two ends sideline; The material of said chi plate 1 is scale board, solid wood plate, rigid plastic sheet or cardboard, can obtain easily on construction ground, and make simple; Easy to operate, can save time, and guarantee work quality.
The course of work of the utility model is referring to shown in Figure 2, and concrete steps are following:
Step 1 ejects steel pipe axis 6 along the pipe shaft direction on the outside surface of tested steel pipe 4;
