Wherein, the first sliding part 3 is slid by a first distance S1 in a direction away from the second ruler rail 2 , and the second sliding part 4 is slid by a second distance in a direction away from the first ruler rail 1 S2, straighten the measuring rope 5 and wind the measuring rope 5 to the second sliding part 4. Reading the scale of the measuring rope 5 at the position of the second sliding part 4 can obtain the corresponding The length of the hypotenuse section X of the outer stirrup.

Specifically, the first ruler rail 1 is a long strip, which can be made of a metal material with a certain strength, for example, made of an unmodified material. The first ruler rail 1 is provided with scales from one end to the other end along the length direction, and the first track 101 is provided along the length direction, that is, the first track 101 and the scales are side by side. The first track 101 can be a through groove running through both sides of the first ruler rail 1, or a groove body such as a dovetail groove, or the first track 101 can also be a track with an I-shaped, T-shaped or dovetail-shaped cross section, as long as the first sliding portion 3 can be slidably connected with the first track 101.

Similarly, the second ruler rail 2 is a long strip, which can be made of a metal material with a certain strength, such as an unmodified material. The second ruler rail 2 is provided with scales from one end to the other end along the length direction, and has scales along the length direction.

The measuring rope 5 is a measuring tool with scales along the length of the rope. In this application, the measuring rope 5 simulates an external stirrup, and the length is read through the scale of the measuring rope 5. Therefore, the starting end of the scale of the measuring rope 5 is the zero-scale end. Connected to the first sliding part 3, the free end can be straightened manually, and then after adjusting the first distance of the first sliding part 3 and the second distance of the second sliding part 4, the measuring rope 5 can be straightened and By pulling the measuring rope 5 around the second sliding part 4, the measuring rope 5 can be simulated as an outer stirrup. The first distance S1 and the second distance S2 are parameter sizes given by the designer when producing external stirrups, which are calculated based on the number and distribution of different anchor bolts M.

The device for calculating the length parameter of the external stirrup of the foot according to the embodiment of the present invention simulates the two anchor bolts M in the foot through the first sliding part 3 and the second sliding part 4, and the first sliding part 3 and the second sliding part Part 4 is slidingly connected to the first ruler rail 1 and the second ruler rail 2 respectively. The first ruler rail 1 and the second ruler rail 2 are vertical, and can be slid by the first distance S1 and the first sliding part 3. The second distance S2 of the second sliding part 4 simulates two anchor bolts M corresponding to the outer stirrup hypotenuse section Straight and wound to the second sliding part 4, the outer stirrups surrounding the two anchor bolts M can be simulated by the measuring rope 5, and what is simulated is exactly the part of the hypotenuse section X of the outer stirrups, and then By reading the length of the corresponding measuring rope 5 at the second sliding part 4, the length of the outer stirrup hypotenuse section X can be obtained. Compared with the method of obtaining the length of the outer stirrup hypotenuse section X through square root calculation It is more convenient to use the foot external stirrup length parameter calculation device provided by the embodiment of the present application to calculate the length of the hypotenuse section It is more convenient for the device to obtain the length of the hypotenuse section X.

As shown in Figure 1, in a specific implementation, the connection point of the first ruler rail 1 and the second ruler rail 2 is the 0 scale of the first ruler rail 1 and the second ruler rail 2 respectively. Location;

Wherein, the two ends of the first rail 101 respectively correspond to the starting and ending positions of the scale on the first ruler rail 1, and the two ends of the second rail 201 respectively correspond to the starting and ending positions of the scale on the second ruler rail 2. The starting and ending positions of the scale.

Specifically, the first ruler rail 1 and the second ruler rail 2 are connected at a right angle. After the two are connected, they form a structure of a right-angled ruler. The 0-scale lines of the two coincide with each other, and the 0-scale line is located at the bend of the right angle. In this way, during use, the staff can move the first sliding part 3 the first distance S1 and the second sliding part 4 the second distance S2 according to the parameters of the outer stirrup given by the technician. Since the first ruler rail 1 and the second The connection between the two ruler rails 2 is at zero scale, then when sliding the first sliding part 3 in the direction away from the second ruler rail 2, the first sliding part 3 can be directly moved to the scale position corresponding to the first distance S1, and the first sliding part 3 can be moved directly to the scale position corresponding to the first distance S1. When the second sliding part 4 slides in the direction away from the first ruler rail 1, the second sliding part 4 can be directly moved to the scale position corresponding to the second distance S2, which is convenient for the staff to operate and read, and then by moving the first sliding part 3 and When the second sliding part 4 reaches the corresponding designated distance, the two anchor bolts M corresponding to the hypotenuse section X of the outer stirrup can be simulated, and the positions of the two anchor bolts M can be simulated.

As shown in Figure 1, in a specific implementation, the measuring rope 5 is connected to the side of the first sliding part 3 away from the space enclosed by the first ruler rail 1 and the second ruler rail 2. .

Specifically, since the outer stirrups surround the outsides of the multiple anchor bolts M, in order to truly simulate the setting of the outer stirrups and obtain the accurate length of the outer stirrup hypotenuse section X, the measuring rope 5 The zero-scale position is connected to the side of the first sliding part 3 away from the space enclosed by the first ruler rail 1 and the second ruler rail 2, thereby allowing the measuring rope 5 to truly simulate the state of the outer stirrup surrounding the anchor bolt M. What is important is that this arrangement enables the measuring rope 5 to simulate that the end of the hypotenuse section X of the outer stirrup is curved around the outside of the anchor bolt M to obtain the actual length of the hypotenuse section X. Then, after the first sliding part 3 and the second sliding part 4 move the first distance S1 and the second distance S2 according to the parameters given by the technician, the measuring rope 5 is straightened and wound to the position of the second sliding part 4, Then the length of the measuring rope 5 read corresponding to the position of the second sliding part 4 includes the length of the curved arc section of the outer stirrup located at both ends of the hypotenuse section X surrounding the outside of the two anchor bolts M. At this time, the obtained The length of the hypotenuse segment X is exactly the same as the real length, which effectively ensures the accuracy of the obtained length of the hypotenuse segment X.

The connection between the measuring rope 5 and the first sliding part 3 can be achieved by clamping with a snap ring, clamping with a strap, or wrapping the measuring rope 5 around the first sliding part 3 and tightening it.

Specifically, after sliding and adjusting the first sliding part 3 and the second sliding part 4, the length of the hypotenuse section The sliding part 6 slides to the position of the anchor bolt M corresponding to the straight side segment Z connected to the outer stirrup hypotenuse section X, that is, moves the third sliding part 6 the third distance S3 or 2 times according to the parameters given by the technician. After S3, straighten the measuring rope 5 and wrap it around the second sliding part 4 and the third sliding part 6 in sequence, and then read the length of the measuring rope 5 through the scale of the third sliding part 6 corresponding to the second ruler rail 2 , then we can obtain the sum of the lengths of the hypotenuse segments X of the external stirrups and the straight-side segments Z of the adjacent hypotenuse segments N (for example, eight footings have four, that is, N=4), the overall length of the outer stirrups can be calculated quickly and easily.
