Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar distance measurement, and more specifically relates to a steel bar distance measurement device for building construction. Background Art

[0002] When a sewage treatment plant is built or expanded, it involves the construction of multiple buildings, and steel bar engineering is an important part of the structure. Steel bars are key structural materials during construction, mainly used to reinforce concrete and provide strength support. After the steel bars are installed, managers need to inspect the spacing of the steel bars to ensure the accuracy of the steel bar size and spacing. Measuring the distance between steel bars is crucial to ensure the stability and safety of the structure, and helps to improve the durability and safety of the structure to ensure the construction quality of the building.

[0003] Traditional inspection of steel bar spacing is generally done manually using a steel tape measure to perform interval inspection of the spacing, and judging whether it is qualified based on the reading of the steel tape measure and the steel bar spacing on the design drawing. This method requires repeated pulling of the steel tape measure for measurement, and most of the time requires the cooperation of others, and requires frequent observation of the tape measure readings. The efficiency of inspecting the steel bar spacing is low and the work intensity is high. At the same time, because the tape measure is made of a soft material, it is easy to bend when it is pulled for a long time, and the judgment error of the steel bar spacing is large.

[0004] Therefore, it is necessary to provide a steel bar distance measuring device for construction to solve the above technical problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-3 and Figure 5-6A steel bar distance measuring device for construction includes: a distance measuring plate 1, in which a placement cavity 2 is provided; a support plate 3, which can be slid up and down and is arranged on the inner wall of the placement cavity 2 and is provided with a plurality of them; a distance measuring bar 4, which is rotatably arranged on the support plate 3, and the distance measuring bar 4 is evenly provided with a plurality of slots 5, and the distances between the plurality of slots 5 on each distance measuring bar 4 are different; a fixing seat 6, which is arranged on the top of the distance measuring plate 1 and is provided with a plurality of them, and a limiting mechanism 7 is provided on the fixing seat 6, which is used to limit the movement of the distance measuring bar 4 in a horizontal state.

[0034] The initial state of the ranging board 1 before use is as follows Figure 1 As shown, when in use, the required distance measuring strip 4 and the support plate 3 in the distance measuring board 1 are slid upward along the placement cavity 2, that is, the distance measuring strip 4 is moved in a vertical state toward the outside of the placement cavity 2. When the distance measuring strip 4 moves to a specified position outside the placement cavity 2, the distance measuring strip 4 is rotated along the support plate 3, so that the distance measuring strip 4 is changed from a vertical state to a horizontal state, as shown in FIG. Figure 5 As shown, the distance measuring strip 4 in this state is then restricted and fixed by the limiting mechanism 7, which can ensure the stability of the distance measuring strip 4 in the subsequent inspection of the steel bar spacing. At this time, the steel bar spacing can be inspected by the distance measuring strip 4 and the slot 5 thereon. The steel bar spacing can be inspected by placing each steel bar in the slot 5 on the distance measuring strip 4 to check whether the steel bar spacing is qualified, avoiding the current method of using a steel tape measure to inspect the steel bar spacing. There is no need to repeatedly pull the steel tape measure for use. One person can operate it without the assistance of multiple people, saving a lot of time and labor, and the work intensity is low; the steel bar that is not aligned with the slot 5 is an unqualified spacing steel bar, which will be easier to find, avoiding the current situation where the readings on the steel tape measure need to be frequently checked to judge, saving a lot of time, and greatly improving the efficiency of inspecting the steel bar spacing. At the same time, the inspection of the distance measuring strip 4 can avoid the bending of the traditional use of the tape measure, greatly reducing the judgment error of the steel bar spacing, with strong practicality, and ensuring the construction quality of the building.

[0035] Before use, the distance measuring strip 4 is in the placement cavity 2 of the distance measuring board 1. When in use, the distance measuring strip 4 is moved out of the distance measuring board 1 and then rotated to a horizontal state for use. The operation is simple and convenient, and each distance measuring strip 4 can be moved, carried and stored conveniently. In addition, the placement cavity 2 of the distance measuring board 1 is equipped with a plurality of distance measuring strips 4, and the spacing of the slots 5 on each distance measuring strip 4 is different. The distance measuring strips 4 with slots 5 of different spacings can be used to inspect steel bars of different spacings, that is, different distance measuring strips 4 can be selected for use according to steel bars of different specifications and spacings on site. The use range is wide and a variety of different needs can be met. At the same time, the device can be reused and can be promoted for use.

[0036] When manufacturing the slot 5 on the distance measuring strip 4, the allowable specification range of the steel bar binding should be considered, and the error value of the slot 5 should be appropriately increased.

[0037] In this embodiment, preferably, please refer to Figure 2-4 and Figure 6 The inner wall of the placement cavity 2 is slidably provided with a plurality of guide rails 8, on which a sliding seat 9 is slidably provided, and the support plate 3 is provided on the sliding seat 9.

[0038] In this embodiment, preferably, please refer to Figure 3-6 The sliding seat 9 is provided with a bracket 10, a pin 11 is rotatably provided on the bracket 10, a transfer rod 12 is provided on the pin 11, and the outer end of the transfer rod 12 is connected to the distance measuring strip 4. The distance measuring strip 4 can be rotated around the pin 11 through the transfer rod 12, that is, when the distance measuring strip 4 is placed in the cavity 2, it is rotated to a vertical state, and when the distance measuring strip 4 is moved out of the cavity 2, it can be rotated to a horizontal state along the pin 11 together with the transfer rod 12, such as Figure 5 , the state of the ranging bar 4 can be easily changed.

[0039] In this embodiment, preferably, please refer to Figure 2 and Figure 4-7 A limiting hole 13 is provided on the transfer rod 12, and the limiting mechanism 7 includes: an inner hidden groove 71, which is provided in the fixing seat 6, and a limiting rod 72 adapted to the limiting hole 13 is slidably arranged in the inner hidden groove 71; a first elastic member 73, one end of which is connected to the limiting rod 72, and the other end is connected to the inner wall of the inner hidden groove 71. The first elastic member 73 in the present application adopts a spring. After the distance measuring strip 4 is moved out of the placement chamber 2, the limiting rod 72 is moved toward the inside of the inner hidden groove 71, and the first elastic member 73 is compressed, and then the transfer rod 12 and the distance measuring strip 4 are rotated along the pin shaft 11 to a horizontal state. At this time, the limiting hole 13 of the transfer rod 12 corresponds to the position of the limiting rod 72. After the limiting rod 72 is released, the limiting rod 72 can be driven to move out of the inner hidden groove 71 by the rebound force of the first elastic member 73, and finally the limiting rod 72 will be inserted into the limiting hole 13 of the transfer rod 12, thereby limiting the movement of the transfer rod 12 and the distance measuring strip 4, ensuring the stability of the distance measuring strip 4 when in use. After the distance measuring strip 4 is used, the limiting rod 72 is moved again to disengage from the limiting hole 13 and enter the inner hidden groove 71, and then the transfer rod 12 and the distance measuring strip 4 can be rotated to a vertical state and moved into the placement chamber 2 for standby.

When the distance measuring strip 4 is in the placement cavity 2 of the distance measuring board 1, the baffle 17 can block the upper end of the distance measuring strip 4, thereby preventing the distance measuring strip 4 from sliding out of the placement cavity 2 during movement or transportation, thereby improving its storage effect. When the distance measuring strip 4 is to be used, the baffle 17 can be pushed to enter the sliding groove 16, and the second elastic member 18 can be compressed, that is, the baffle 17 no longer blocks the removal of the distance measuring strip 4. When the distance measuring strip 4 is used and enters the placement cavity 2, the baffle 17 can be driven by the second elastic member 18 to restore the initial position, and at this time the baffle 17 can block the top of the distance measuring strip 4 to restrict its movement, thereby ensuring the overall stability of the distance measuring board 1.
