Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of the directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as shown in reference to fig. 1, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In order to solve the problem that the line type of the bottom of the guardrail template is easy to control through a control line on the bridge floor 2, but the top of the template is difficult to position, the utility model provides a linear positioning tool for the bridge guardrail template, which is shown in figures 1 and 2.

A linear positioning tool for a bridge guardrail template comprises a support frame 1 vertically arranged on a bridge floor 2, wherein one side of the support frame 1 is provided with a scale 5, and the linear shape of the top of the guardrail template is controlled through the scale 5;

the support frame 1 comprises a vertical rod 1a arranged in the vertical direction, the bottom of the vertical rod 1a is supported on a control line of the bridge deck 2, the bottom of the vertical rod 1a is fixedly connected with one end of a bottom plate 1b, and the bottom plate 1b is attached to the bridge deck 2; extension rod 4 that the level set up is installed at the top of montant 1a, and extension rod 4 perpendicular to bridge floor 2's control line, downwardly extending's scale 5 is installed to the tip of extension rod 4, and the lower extreme of scale 5 aligns with the top of guardrail template.

According to the utility model, the bottom of the support frame 1 is subjected to position control through a control line on the bridge floor 2 through the fixed support frame 1, and then the top of the template is positioned through a scale 5 arranged on the top of the support frame.

Specifically, the vertical rod 1a is vertically arranged, the bottom of the vertical rod 1a is supported on a control line, the top of the vertical rod 1a is provided with an extension rod 4 horizontally extending towards the direction of the template, the tail end of the extension rod 4 is fixed with a scale 5 extending downwards, and the position of the bottom of the scale 5 can be determined and kept still only by keeping the vertical rod 1a and not rotating. Therefore, the bottom of the vertical rod 1a is also connected with a bottom plate 1b, and the bottom plate 1b is attached to the bridge deck 2. The bottom plate 1b is pressed against the bottom plate 1b without moving.

As shown in fig. 1, since the deck 2 is not a horizontal plane but a curved surface, the bottom plate 1b is attached to the deck 2 at an angle with the horizontal plane, i.e. an angle θ in fig. 1. The size of this angle θ is proportional to the distance of the bottom plate 1b from the central line of the deck 2, while the guardrails are arranged generally parallel to the central line of the deck 2 and the control lines are at the same distance from the centre of the deck 2. Therefore, a cross section is made at any position of the bridge deck 2, and the included angles theta between the bridge deck 2 at the control line position and the horizontal plane are the same. Because the vertical rod 1a is ensured to be vertical, it is easy to see that the included angle between the vertical rod 1a and the bottom plate 1b is only required to be 90 degrees and theta is reduced.

As shown in fig. 2, the scale 5 is slidably mounted on the end of the extension rod 4; the end part of the extension rod 4 is provided with a vertically arranged sliding barrel 6, the scale 5 is slidably arranged in the sliding barrel 6, the side wall of the sliding barrel 6 is in threaded connection with a first set screw 7, and the end part of the first set screw 7 tightly props against the scale 5 to lock the scale 5 to slide. The scale 5 is provided with a first scale mark, the sliding barrel 6 is provided with a first indicating part for marking the first scale mark, and the number of the first indicating part corresponds to the horizontal height from the bottom of the scale 5 to the bridge floor 2. Before using, the height of the scale 5 is adjusted to a proper position according to the elevation of the top of the guardrail template, and then the first set screw 7 is screwed. The first indicator may be a pointer mounted on the slide or on the extension rod. Alternatively, a portion of the slide may be defined, such as the upper surface or the lower surface, and the end indicator need only indicate the position where the first graduation mark is clear.

For the convenience of observation, the lower end of the scale 5 is pointed. As shown in fig. 1, it is only necessary to determine the position of the guardrail corresponding to the scale 5 in advance, and the scale 5 is corresponding to the inner side of the guardrail in the figure.

As shown in fig. 1 and 2, the extension rod 4 is horizontally slidably mounted on the top of the vertical rod 1a, and the extension rod 4 is locked with the vertical rod 1a by a second set screw 8. The extension rod 4 is provided with a second scale mark, the vertical rod 1a is provided with a second indicating part for marking the second scale mark, and the number of the second indicating part corresponds to the vertical distance between the projection of the scale 5 on the bridge floor 2 and the control line.

In order to keep the stability of the whole structure of the support frame 1, the support frame 1 further comprises an inclined rod 1c, two ends of the inclined rod 1c are respectively fixed with the top of the vertical rod 1a and the end of the bottom plate 1b far away from the vertical rod 1a, and the vertical rod 1a, the bottom plate 1b and the inclined rod 1c form a triangular structure. Specifically, as shown in fig. 1, the support frame 1 is made of steel, and is fixed by welding to be integrated between the diagonal bar 1c and the vertical bar 1a, and a connecting rod reinforcing structure is further provided.

The working mode of the utility model is as follows: the support frame 1 is arranged in place by taking a control line which is measured on the bridge floor 2 in advance as a reference, the vertical rod 1a is kept to be vertically arranged, the extension rod 4 horizontally points to one side of the guardrail template, and then the extension rod 4 slides left and right to a proper position and is fixed through the second set screw 8. The scale 5 is then slid up and down and fixed by a first set screw 7. The position above the fence template can now be determined from the position of the scale 5, and the entire positioning tool moved to the next location after template fixation is complete.

Generally, the guardrails of the same bridge are of the same standard, and the heights of the guardrails are the same, so that the extension rod 4 and the scale 5 only need to be adjusted once.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
