Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a steel cage stirrup detection ruler. Background Art

[0002] In municipal bridge projects, the processing and production quality of bridge cast-in-place pile steel cages is particularly important. The steel cages are made in a steel processing yard or a temporary steel processing shed at the construction site, transported to the site by a flatbed truck, then lifted by a crane, placed in the drilled hole and the concrete pouring is completed.

[0003] In order to ensure the quality of pile foundation construction, it is necessary to detect whether the transverse spacing of the stirrups and the radial deviation of the stirrups meet the requirements. Therefore, the steel cage needs to be tested after it is processed. At present, the detection of the transverse spacing of the stirrups is usually carried out one by one by measuring with a tape measure, while the radial deviation of the stirrups is detected by placing a steel ruler on the stirrups to observe their horizontality. The current detection method has a large workload, low detection efficiency and a long detection time. Utility Model Content

[0025] Example, see Figure 1-3 A steel cage stirrup detection ruler comprises a first scale plate 1 and a second scale plate 2, a plurality of notches 3 are provided at equal intervals at the bottom of the first scale plate 1 and the second scale plate 2, a level tube 4 is fixed on the first scale plate 1 and the second scale plate 2, the backs of the first scale plate 1 and the second scale plate 2 are hinged by a hinge 5, the fronts of the first scale plate 1 and the second scale plate 2 are connected by a lock 6, the lock 6 comprises a first fixed column 61, a second fixed column 62 and a movable piece 63, the first fixed column 61 is fixed on the first scale plate 1, the second fixed column 62 is fixed on the second scale plate 2, one end of the movable piece 63 is rotatably connected to the first fixed column 61, and the other end is provided with a slot 631, and the slot 631 can be inserted into the second fixed column 62.

[0026] The first foot plate 1 and the second foot plate 2 of the utility model can be rotated relative to each other through the hinge 5 to be folded and unfolded, which is convenient for storage, and the folding and unfolding states can be flexibly selected according to the length of the steel cage 10 to be detected. When unfolding, the movable plate 63 is rotated, and the slot 631 of the movable plate 63 is inserted into the second fixed column 62, so that the first foot plate 1 and the second foot plate 2 are fixedly connected to avoid mutual rotation affecting the detection.

[0027] The utility model can be tested in both the folded and unfolded states. The spacing of the notches 3 is set according to the qualified value of the transverse spacing of the stirrups. Figure 4 The figure shows that the test is carried out in a folded state. During the test, the detection ruler is placed against the steel cage 10. If the stirrups can be smoothly inserted into the slots 3, it means that the lateral spacing of the stirrups meets the requirements. If there are stirrups that cannot be inserted into the slots 3, it means that the lateral spacing of the stirrups does not meet the requirements. On the basis that the lateral spacing of the stirrups meets the requirements, observe the level tube 4 on the first scale plate 1 and the second scale plate 2. If the bubble in the level tube 4 is centered, it means that the radial deviation of the stirrups meets the requirements. The utility model can detect whether the lateral spacing of the stirrups meets the requirements at one time through a plurality of slots 3, and can directly detect whether the radial deviation of the stirrups meets the requirements through the level tube 4. The workload is small, the detection efficiency is high, and the detection time is short.

When the slot 631 of the movable sheet 63 is inserted into the second fixing column 62, the second fixing column 62 can be tightened to press the movable sheet 63 onto the second scale plate 2 to prevent the movable sheet 63 from slipping out of the second fixing column 62.

[0029] In a specific embodiment, handles 7 are fixed on the tops of the first scale plate 1 and the second scale plate 2 to facilitate the movement of the detection scale.

[0030] In a specific embodiment, the first scale plate 1 and the second scale plate 2 are provided with through holes 8 at ends away from each other, and ropes can be tied in the through holes 8 to hang the detection ruler at a conspicuous position on the construction site for easy retrieval and replacement.

[0031] In a specific embodiment, a scale ruler 9 is fixed to the lower front side of the first scale plate 1 and the second scale plate 2, and the scale of the scale ruler 9 corresponds to the position of the slot 3. The spacing of the slot 3 can be intuitively seen through the scale ruler 9, and the lateral deviation value of the stirrup can also be directly observed when the stirrup cannot be inserted into the slot 3.

[0032] In a specific embodiment, the slot 631 is an arc slot.

[0033] In a specific embodiment, the two level tubes 4 are embedded in the front side of the first scale plate 1 and the second scale plate 2 to reduce the volume of the detection ruler.

[0034] In a specific embodiment, the first scale board 1 and the second scale board 2 are composite bamboo plywood, steel plate or aluminum alloy plate.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
