Angle-adjustable diagonal bracing reinforced bolted gusset structure

Abstract

The utility model discloses an angle adjustable inclined strut reinforcing anchoring pad structure for solving the technical problem that the detection equipment cannot work because of no place to place the flat base surface when carrying out horizontal anchoring pulling detection on the inclined strut. The structure comprises a fixed vertical plate and a movable horizontal plate, both of which are hinged on the inclined strut through a hoop at one end and movably connected at the other end. The core lies in that a linkage mechanism composed of an adjusting screw, a sliding block and a pin shaft drives the fixed vertical plate to rotate around the top hinge point, so that the inclination angle can be accurately adjusted, and the plate surface of the fixed vertical plate is finally locked in the direction perpendicular to the horizontal anchoring axis. The utility model can provide a stable and reliable bearing plane for the pulling detection equipment, is quick to install, accurate to adjust, highly universal, and greatly improves the safety and efficiency of the detection operation.

Description

Technical Field

[0001] This utility model relates to the field of structural reinforcement and testing technology in building engineering, specifically an angle-adjustable diagonal bracing reinforcement rebar pad structure. Background Technology

[0002] In building structure reinforcement and foundation pit support projects, it is often necessary to install rebar on existing structures. When the rebar is installed at the location of inclined components such as diagonal braces, to ensure that the direction of the rebar meets the design requirements, it is often necessary to make a certain angle with the surface of the diagonal brace, such as horizontally. After such horizontal rebar installation is completed, pull-out tests are required to verify its anchorage performance. However, due to the inclination angle of the diagonal brace itself, it is difficult to place the base of the testing equipment stably, making it impossible to form a stable force-bearing plane perpendicular to the axis of the rebar. Existing technology lacks dedicated tooling to solve this problem, and temporary welding or support methods are usually used, which have problems such as cumbersome installation, poor stability, low versatility, and potential damage to the original components, seriously affecting the efficiency and safety of the testing work. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an angle-adjustable diagonal bracing reinforcement rebar pad structure. By adjusting the relative angle between the movable horizontal plate and the fixed vertical plate, the fixed vertical plate can be precisely adjusted to a direction perpendicular to the horizontal rebar axis, thereby providing a stable and reliable support plane for the pull-out testing equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an angle-adjustable diagonal brace reinforcement anchor plate structure, including a fixed vertical plate and a movable horizontal plate, wherein one end of the fixed vertical plate and the movable horizontal plate is provided with a clamp, and one end of the fixed vertical plate and the movable horizontal plate is fixed to the diagonal brace by the clamp. The fixed vertical plate and the movable horizontal plate are movably connected at their other ends.

[0005] In a preferred embodiment, a first connecting lug is provided on one side of the clamp, and a second connecting lug is provided at one end of the fixed vertical plate and the movable horizontal plate.

[0008] In a preferred embodiment, the lower end of the fixed vertical plate is provided with a first pin slot, in which a pin is installed, and one end of the slider is provided with a second pin slot, in which the portion of the pin located outside the first pin slot is inserted.

[0009] In a preferred embodiment, the slider is provided with a screw hole, and the slide groove is provided with an adjusting screw parallel to the end of the movable cross plate. The adjusting screw passes through the screw hole on the slider.

[0010] In a preferred embodiment, the fixed vertical plate is provided with through holes for horizontal rebar to pass through on the existing structure.

[0011] The present invention provides an angle-adjustable diagonal bracing reinforcement rebar pad structure, which has the following beneficial effects by adopting the above structure: (1) By driving the fixed vertical plate through the movable horizontal plate to adjust the angle, the plate surface of the fixed vertical plate can be precisely adjusted to be perpendicular to the horizontal anchoring axis, providing a rigid, reliable support plane perpendicular to the force direction for the pull-out testing equipment, completely solving the problem of the equipment not being able to be placed flat on the inclined surface and the force being eccentric, greatly improving the accuracy of the test data and the safety of operation.

Detailed Implementation

[0019] like Figure 1-5 In the present invention, an angle-adjustable diagonal brace reinforcement rebar pad structure includes a fixed vertical plate 3 and a movable horizontal plate 4. One end of the fixed vertical plate 3 and the movable horizontal plate 4 is provided with a clamp 5, and one end of the fixed vertical plate 3 and the movable horizontal plate 4 is fixed to the diagonal brace by the clamp 5. The fixed vertical plate 3 and the movable horizontal plate 4 are movably connected at their other ends.

[0020] In a preferred embodiment, the clamp 5 is provided with a first connecting lug 6 on one side, and a second connecting lug 9 is provided at one end of the fixed vertical plate 3 and the movable horizontal plate 4. The fixed vertical plate 3 and the movable horizontal plate 4 are respectively hinged to the clamp 5 through the first connecting lug 6 and the second connecting lug 9 with a pin.

[0021] In a preferred embodiment, a tightening bolt 7 is provided on the other side of the clamp 5. The tightening bolt 7 passes through the side wall of the clamp 5 and has a top head 8 at its end inside the clamp 5.

[0022] In a preferred embodiment, the movable horizontal plate 4 has a notch 10 on the side away from the clamp 5, and a sliding groove 11 is provided on the movable horizontal plate 4 on one side of the notch 10. A slider 12 is provided in the sliding groove 11. The lower end of the fixed vertical plate 3 is located in the area of ​​the notch 10, and one end of the slider 12 is connected to the fixed vertical plate 3.

[0023] In a preferred embodiment, the lower end of the fixed vertical plate 3 is provided with a first pin slot 14, a pin 15 is installed in the first pin slot 14, and one end of the slider 12 is provided with a second pin slot 16, with the portion of the pin 15 located outside the first pin slot 14 inserted into the second pin slot 16.

[0024] In a preferred embodiment, the slider 12 is provided with a screw hole 17, and the slide groove 11 is provided with an adjusting screw 13 parallel to the end of the movable horizontal plate 4. The adjusting screw 13 is set through the screw hole 17 on the slider 12.

[0025] In a preferred embodiment, the fixed vertical plate 3 is provided with through holes 18 for the horizontal reinforcing bars 2 of the existing structure 1 to pass through.

[0026] When performing horizontal rebar installation 2 inspection using this utility model: Pass the through hole 18 on the fixed vertical plate 3 through the horizontal anchor bar 2 and use the clamp 5 to fix the upper end of the fixed vertical plate 3 to the upper part of the diagonal brace.

[0027] Manually swing the movable horizontal plate 4 roughly, and bring one end of the clamp 5 close to the lower part of the diagonal brace. Fix the clamp 5 to the diagonal brace, tighten the top bolt 7, and press the surface of the diagonal brace with the top head 8 to achieve the initial fixation of the device.

[0028] At this time, the adjusting screw 13 is rotated. Since the adjusting screw 13 engages with the screw hole 17 of the slider 12, and the slider 12 is restricted within the groove 11 and cannot rotate, the rotational motion is converted into the linear motion of the slider 12.

[0029] When the slider 12 moves forward (towards the diagonal brace) or backward (away from the diagonal brace), it applies a pushing or pulling force to the end of the fixed vertical plate 3 through the hinge point of the pin 15.

[0030] This force forces the fixed vertical plate 3 to rotate around the hinge point where its top connects to the clamp. By adjusting the screw in either the forward or reverse direction, the tilt angle of the fixed vertical plate 3 can be changed continuously and precisely.

[0031] Place a right-angle ruler on the upper plane of the movable horizontal plate 4. Observe the right-angle ruler while rotating the adjusting screw 13. When the plate surface of the fixed vertical plate 3 is completely in contact with the other side of the right-angle ruler, it means that the plate surface has been adjusted to be perpendicular to the axis of the horizontal rebar 2.

[0032] Place the base of the pull-out testing equipment firmly against the surface of the leveled fixed vertical plate 3, and allow the rebar to pass through the center hole of the equipment to complete the equipment installation. Then, the testing operation can be carried out.

[0033] After the test is completed, loosen the testing equipment and rotate the adjusting screw 13 in the opposite direction to loosen the structure, so that the device can be easily removed from the diagonal brace and the rebar.
