Description

Technical Field

[0001] The utility model relates to construction detection equipment, in particular to a pier body steel bar protective layer detection ruler. Background Art

[0002] In the existing construction process, after the pier body formwork is installed, the thickness of the steel bar protective layer is mainly measured by a tape measure, which consumes a lot of manpower, has extremely low construction efficiency, and cannot guarantee accuracy. In order to improve measurement accuracy and efficiency, construction workers often use detection angle rulers to measure the thickness of the protective layer.

[0003] However, when using the detection angle ruler, it is often difficult to control the accurate verticality of the pier body formwork, resulting in a certain deviation in the data after measuring the thickness of the steel bar protective layer. Utility Model Content

[0004] The purpose of the utility model is to provide a pier body steel bar protection layer detection ruler, which is used to solve the problem that when the detection angle ruler is used, it is often difficult to control the accurate vertical pier body template, resulting in a certain deviation in the data after the steel bar protection layer thickness measurement.

[0005] To achieve the above-mentioned purpose, the utility model provides a pier body steel bar protective layer detection ruler, including a holding plate, a scale angle plate is fixedly installed at the bottom of which, the scale angle plate is a trapezoidal structure, and a plurality of groups of scale lines are marked in parallel in the horizontal direction on the upper side, and a group of positioning plates are hinged on both sides of the holding plate respectively, and each group of the positioning plates is connected to a sliding block slidably installed on the holding plate through a corresponding transmission plate, and the sliding block is driven by a driving member on the holding plate to slide linearly, and the corresponding positioning plates are driven to rotate by the two groups of transmission plates.

[0006] As a further solution of the utility model, the holding plate is provided with a connecting slide groove for the sliding block to slide.

[0007] As a further solution of the utility model, the driving member is a driving screw rod, the driving screw rod is rotatably mounted on the holding plate and passes through a connecting slide groove, and the sliding block and the driving screw rod form a spiral pair transmission.

[0008] As a further solution of the utility model, a rotary cap is installed at the end of the driving screw.

[0009] Compared with the prior art, the utility model drives the sliding block to move by rotating the driving screw during measurement, and the transmission drives the two sets of positioning plates to be perpendicular to the two sides of the holding plate, so that when the holding plate is placed on the pier body template, it can be positioned perpendicular to it, thereby ensuring that the scale angle plate and the steel bars in contact with the pier body are in a vertical state, thereby improving the accuracy of the measurement.

[0013] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0014] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, a pier body steel bar protective layer detection ruler comprises a holding plate 1, a scale angle plate 2 is fixedly installed at the bottom thereof, the scale angle plate 2 is a trapezoidal structure, and multiple groups of scale lines are marked in parallel in the horizontal direction in sequence, and a group of positioning plates 8 are respectively hinged on both sides of the holding plate 1, and each group of the positioning plates 8 is connected to the sliding block 5 slidably installed on the holding plate 1 through the corresponding transmission plate 7. The sliding block 5 is driven by the driving member on the holding plate 1 to slide linearly, and the two groups of transmission plates 7 drive the corresponding positioning plates 8 to rotate;

[0015] In the utility model, when the thickness of the steel bar protective layer is actually measured, the sliding block 5 is driven by the driving member to move linearly, and the transmission belt converts the movement of the sliding block 5 into the rotation of the two groups of positioning plates 8. When the sliding plate slides to the end of the stroke, the two groups of positioning plates 8 are perpendicular to the two sides of the holding plate 1. At this time, when the surveyor places the holding plate 1 on the pier body template 4, the holding plate 1 and the scale angle plate 2 fixed at the bottom thereof are in a vertical state with the pier body template 4, thereby ensuring that the scale angle plate 2 is in a vertical state with the steel bars 3 in contact with the pier body, thereby improving the accuracy of the measurement.

[0016] like Figure 1 As shown, in the embodiment of the utility model, the holding plate 1 is provided with a connecting slide groove 101 for the sliding block 5 to slide, and the inner walls on both sides of the connecting slide groove 101 are provided with positioning grooves for the end side of the sliding block 5 to be inserted and limited, and the sliding of the sliding block 5 is guided by the connecting slide groove 101;

[0017] At the same time, the driving member is a driving screw 6, which is rotatably mounted on the holding plate 1 and passes through the connecting slide 101. The sliding block 5 and the driving screw 6 form a spiral pair transmission. At the same time, a rotary cap 601 is installed at the end of the driving screw 6. When the sliding block 5 is driven, the driving screw 6 is driven to rotate by rotating the rotary cap 601, and the spiral transmission drives the sliding block 5 to move linearly along the connecting slide 101.

[0018] Of course, in actual design, the driving member may also be replaced by a member that can realize the locking driving capability of the sliding block 5, such as a fixing structure such as a fixing bolt.

[0019] In summary, when the utility model is measuring, the sliding block 5 is driven to move by rotating the driving screw 6, and the transmission drives the two sets of positioning plates 8 to be perpendicular to the two sides of the holding plate 1, so that when the holding plate 1 is placed on the pier body template 4, it can be positioned perpendicular to it, thereby ensuring that the scale angle plate 2 and the steel bars 3 in contact with the pier body are in a vertical state, thereby improving the accuracy of the measurement.

[0020] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
