Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology in building engineering; specifically, this utility model relates to a steel bar hook detection ruler and a multi-model steel bar hook detection combination tooling. Background Technology

[0002] Reinforced concrete construction is an indispensable and crucial component of building engineering. In recent years, while strengthening overall construction quality control, various regions have placed increasing emphasis on the construction quality of reinforced concrete, implementing various measures to control and reduce the occurrence of reinforced concrete accidents. In reinforced concrete engineering, the first aspect to control is the quality of the hooks at the ends of the reinforcing bars. If the angle of the hooks is not properly controlled, it directly affects the anchorage capacity and may even cause anchorage failure, seriously impacting the building's quality. Currently, there is no standard measuring tool for reinforcing bar hooks, making it impossible to accurately determine whether the bending radius, angle, and straight section length of the reinforcing bars are up to standard during post-processing acceptance. Utility Model Content

[0003] In view of this, this utility model provides a rebar hook inspection ruler and a multi-model rebar hook inspection combination tool to solve the problem of not being able to accurately determine whether the bending radius, angle and straight section length of the rebar hook are qualified during the acceptance of rebar processing, and to achieve effective control of the quality acceptance of rebar hooks.

[0004] To achieve the aforementioned objectives, the first aspect of this utility model provides a rebar hook detection ruler, comprising:

[0005] The longitudinal straight section is used to rest against the inner side of the longitudinal part of the rebar hook to measure the length parameter of the straight section of the rebar hook.

[0006] The horizontal straight section is used to rest against the inner side of the horizontal part of the rebar hook;

[0007] The arc-shaped part is set between the outer sides of the longitudinal straight segment and the transverse straight segment, and is used to rest against the inner side of the bend of the rebar hook to measure the bending radius of the rebar hook.

[0008] The longitudinal straight segment is perpendicular to the transverse straight segment.

[0009] In the steel bar hook measuring ruler described above, optionally, a straight-curved dividing line is provided at the junction of the horizontal straight section and the arc section.

[0010] In the steel bar hook measuring ruler described above, optionally, the longitudinal straight section is provided with measuring scale lines distributed sequentially from bottom to top.

[0011] The second aspect of the present utility model provides a combined tooling for detecting multi - model steel bar hooks, including a plurality of the above - mentioned steel bar hook detection rulers. Each steel bar hook detection ruler is respectively used to detect steel bar hooks with different hook radii and straight - segment lengths. One end of the transverse straight - segment parts of the plurality of steel bar hook detection rulers, which is far from the arc - shaped part, commonly passes through a connecting bolt.

[0012] In the combined tooling for detecting multi - model steel bar hooks as described above, optionally, the plurality of steel bar hook detection rulers are arranged in ascending order of the length of their longitudinal straight - segment parts along the length direction of the connecting bolt.

[0013] In the combined tooling for detecting multi - model steel bar hooks as described above, optionally, a fixing plate is fixedly arranged at one end of the bolt where the straight - segment part is the shortest. The top of the fixing plate passes through the sides and tops of each steel bar hook detection ruler in a state of keeping close to each steel bar hook detection ruler. Jacks are arranged at the tops of the steel bar hook detection rulers, and fixing pieces are inserted into the jacks, and the fixing pieces are slidably arranged on the fixing plate.

[0014] In the combined tooling for detecting multi - model steel bar hooks as described above, optionally, the cross - section of the fixing piece is in a "匚" - shaped structure with the opening facing downwards, and the widths of the two longitudinal parts of the fixing piece are greater than the width of its middle part. The longitudinal part and the middle part of the fixing piece on the side inserted into the jack are both slidably arranged in the fixing piece, and the other longitudinal part of the fixing piece is located outside the fixing plate.

[0015] In the combined tooling for detecting multi - model steel bar hooks as described above, optionally, a through - groove for the sliding of the middle part of the fixing piece and a groove for the sliding of the side part of the fixing piece inserted into the jack are arranged on the fixing plate. The longitudinal part of the fixing piece located outside the fixing plate has an arc - shaped structure with a sunken surface.

[0016] The steel bar hook detection ruler of the present utility model is more convenient and fast for the quality acceptance of the hooks at the ends of steel bars, effectively controls the hook quality, ensures the steel bar processing quality, and thus improves the quality of the engineering entity.

[0017] The combined tooling for detecting multi - model steel bar hooks of the present utility model combines the steel bar hook detection rulers corresponding to multi - model steel bar hooks into a combined tooling, enabling workers to select the corresponding detection ruler for acceptance detection operations according to different models of steel bar hooks, greatly facilitating the detection operations of workers and improving the operation efficiency.

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 As shown, Embodiment 1 of this utility model provides a rebar hook detection ruler, comprising:

[0030] The longitudinal straight segment 1 is used to rest against the inner side of the longitudinal segment 9.1 of the rebar hook to measure the length parameter of the straight segment of the rebar hook;

[0031] The horizontal straight section 2 is used to rest against the inner side of the horizontal section of the steel bar hook;

[0032] The arc-shaped part 3 is set between the outer sides of the longitudinal straight segment part 1 and the transverse straight segment part 2, and is used to rest against the inner side of the bend of the steel bar hook to measure the bending radius of the steel bar hook.

[0033] The longitudinal straight segment 1 and the transverse straight segment 2 are set perpendicularly.

[0034] The steps are as follows:

[0035] Step 1: Consult the construction technical specifications, acceptance standards, and drawings for relevant requirements on rebar hooks, and clarify the parameters such as bending radius, angle, and straight segment length of the end hooks for each type of rebar.

[0036] Step 2: Based on the relevant parameters collected above, use a 2mm thick stainless steel plate to process a measuring ruler for the corresponding type of steel bar.

[0037] Step 3: Use a combination of tools to inspect the quality of the rebar hooks.

[0038] By using the rebar hook inspection ruler provided in this embodiment to inspect the quality of the end hooks of rebars, the acceptance of rebar hooks becomes more convenient and faster, effectively controlling the quality of hooks, ensuring the quality of rebar processing, and thus improving the quality of the project entity.

[0039] Furthermore, a straight-curved dividing line 4 is provided at the junction of the horizontal straight segment 2 and the arc segment. Measurement scale lines 5 are provided on the vertical straight segment 1, distributed sequentially from bottom to top.

[0040] like Figures 1 to 3 As shown, Embodiment 2 of this utility model provides a multi-model rebar hook detection assembly, comprising multiple rebar hook detection rulers manufactured according to different models of rebar hooks as described in Embodiment 1. Each rebar hook detection ruler is used to detect rebar hooks with different hook radii and straight segment lengths. A connecting bolt 6 passes through the ends of the horizontal straight segment 2 of the multiple rebar hook detection rulers away from the arc-shaped portion 3. The connecting bolt 6 connects the multiple rebar hook detection rulers to form a stable assembly. When one model of rebar hook detection ruler is needed, it can be turned out by loosening the connecting bolt 6.

[0041] like Figure 4 As shown, in a relatively specific embodiment, multiple rebar hook measuring rulers are arranged in ascending order of length along the longitudinal straight segment 1 of the connecting bolt 6. This makes it easier for workers to select the corresponding rebar hook measuring ruler according to the different models of the rebar hooks.

[0042] like Figures 4 to 8 As shown, the connecting bolt 6 is fixedly installed at one end of the shortest rebar hook measuring ruler in the straight section, with a fixing plate 7. The top of the fixing plate 7 is kept in close contact with each rebar hook measuring ruler and passes through the side and top of each rebar hook measuring ruler in sequence. Each rebar hook measuring ruler has an insertion hole 8 at its top, and a fixing piece 9 is inserted into each insertion hole 8. The fixing piece 9 is slidably mounted on the fixing plate 7.

[0043] In the initial state, except for the longest rebar hook measuring ruler in the longitudinal straight section 1, all rebar hook measuring rulers are fixed in an aligned state by inserting fixing pieces 9 into the insertion holes 8 at their top.

[0044] When one of the rebar hook measuring rulers is needed, the worker only needs to push the corresponding fixing plate 9 up so that the fixing plate 9 is disengaged from the insertion hole 8. Then, the required rebar hook measuring ruler can be turned out. At this time, the remaining rebar hook measuring rulers are still effectively fixed, which makes it easier for workers to use. This avoids directly loosening the connecting bolt 6, which would cause all the rebar hook measuring rulers to become loose and interfere with the worker's inspection work.

[0045] The fixing plate 9 has a downward-facing "U"-shaped cross-section, and the width of its two longitudinal portions 9.1 is greater than the width of its middle portion 9.2. The longitudinal portion 9.1 and its middle portion 9.2 on the side of the fixing plate 9 that inserts into the insertion hole 8 are slidably disposed within the fixing plate 9, while the other longitudinal portion 9.1 is located outside the fixing plate 7. This arrangement effectively confines the fixing plate 9 to the fixing plate 7, improving its stability. Both the fixing plate 7 and the fixing plate 9 can be made of stainless steel sheet, giving them a certain degree of rigidity and toughness.

[0046] The fixing plate 7 is provided with a through groove 10 for sliding the middle part 9.2 of the fixing piece 9 and a groove 11 for sliding the side part of the fixing piece 9 into the insertion hole 8. The longitudinal part 9.1 of the fixing piece 9 located on the outer side of the fixing plate 7 has an arc-shaped structure with its surface concave inward. This arrangement ensures that the side of the fixing piece 9 and the fixing plate 7 facing the rebar hook measuring ruler remains in close contact with the rebar hook measuring ruler.

[0047] Specifically, in this embodiment, the multiple rebar hook measuring rulers correspond to the following rebar hook models in ascending order of size: 12mm diameter rebar hook, 14mm diameter rebar hook, 16mm diameter rebar hook, 20mm diameter rebar hook, 22mm diameter rebar hook, 25mm diameter rebar hook, 28mm diameter rebar hook, and 32mm diameter rebar hook.

[0048] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
