Description

Technical Field

[0001] This utility model relates to the field of rebar spacing detection technology, specifically a rebar spacing detection device for building construction supervision. Background Technology

[0002] Rebar spacing inspection is a crucial quality control step in construction engineering, directly affecting the load-bearing capacity, durability, and safety of concrete structures.

[0003] Measuring tapes are a common tool used by construction supervisors to measure the distance between steel bars (usually referring to steel bars in concrete structures). They are simple and convenient to operate. However, in actual testing, the tape measure is prone to left and right deviation and cannot be perpendicular to the two steel bars, resulting in inaccurate test data. Based on this, a steel bar spacing testing device for construction supervision is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a steel bar spacing detection device for building construction supervision in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebar spacing detection device for construction supervision, comprising a measuring tape assembly consisting of a measuring tape shell, a measuring tape strap, and a hook. The measuring tape strap is wound inside the measuring tape shell, and one end of the measuring tape strap extends through to the outside of the measuring tape shell and is connected to the hook. Two connecting seats are symmetrically fixed on the outside of the measuring tape shell above the outlet of the measuring tape strap. An anti-deviation auxiliary component is connected to the measuring tape shell through the connecting seats. The anti-deviation auxiliary component cooperates with the hook to realize the detection of rebar spacing.

[0006] The anti-deviation auxiliary component includes a convex block, a connecting pin, and a concave stop block;

[0007] The convex blocks are distributed in the middle of the two connecting seats, and the convex blocks are rotatably connected to the connecting seats by connecting pins;

[0008] The concave stop is fixed to the bottom of the convex block. The concave stop is sleeved on the outside of the measuring tape and protrudes below the measuring tape when facing downward. The concave stop and the hook are respectively attached to the outside of the two steel bars to realize the detection of the spacing of the steel bars.

[0009] As a further improvement of this utility model: a notch is provided in the center of the top of the concave stop block, and the width of the notch is smaller than the width of the measuring tape.

[0010] As a further embodiment of this utility model: the width of the inner wall of the concave stop is greater than the width of the measuring tape, and the horizontal height of the top of the inner wall of the concave stop is higher than the horizontal height of the measuring tape.

[0011] As a further improvement of this utility model: L-shaped storage grooves are provided on both sides of the outer wall of the measuring tape shell above the connecting seat. The L-shaped storage grooves are used to provide storage space for the concave stop block that is flipped upward.

[0012] As a further embodiment of this utility model: the connecting seat and the L-shaped storage groove are integrally formed on the outer side of the measuring tape shell by injection molding, and the convex block, connecting pin, and concave stop block are integrally formed by injection molding.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4In this embodiment of the utility model, a rebar spacing detection device for construction supervision includes a measuring tape assembly 1 consisting of a measuring tape shell 101, a measuring tape strap 102, and a hook 103. The measuring tape strap 102 is wound inside the measuring tape shell 101, and one end of the measuring tape strap 102 extends through to the outside of the measuring tape shell 101 and is connected to the hook 103. Two connecting seats 104 are symmetrically fixed on the outside of the measuring tape shell 101 above the outlet of the measuring tape strap 102. The measuring tape shell 101 is connected to an anti-deviation auxiliary component 2 through the connecting seats 104. The anti-deviation auxiliary component 2 cooperates with the hook 103 to realize the spacing detection of the rebars 3.

[0022] Anti-deviation auxiliary component 2 includes a convex block 201, a connecting pin 202, and a concave stop block 203;

[0023] The convex blocks 201 are distributed in the middle of the two connecting seats 104, and the convex blocks 201 are rotatably connected to the connecting seats 104 through the connecting pins 202;

[0024] The concave stop 203 is fixed to the bottom of the convex block 201. The concave stop 203 is sleeved on the outside of the measuring tape 102 and protrudes to the bottom of the measuring tape 102 in the downward state. The concave stop 203 and the hook 103 are respectively attached to the outside of the two steel bars 3 to realize the spacing detection of the steel bars 3.

[0025] The outer walls of the measuring tape housing 101 are provided with L-shaped storage slots 105 on both sides above the connecting seat 104. The L-shaped storage slots 105 are used to provide storage space for the concave stop block 203 that is flipped upward.

[0026] In this embodiment, it should be noted that the measuring tape assembly 1 is a common measuring tape on the market. The winding structure of the measuring tape tape 102 inside the measuring tape housing 101 is the same as the winding structure of the measuring tape on the market. Therefore, its internal winding structure will not be described in detail here.

[0027] The procedure for inspecting the spacing of rebar 3 is as follows:

[0028] In normal use, the anti-deviation auxiliary component 2 is stored inside the L-shaped storage slot 105, which does not affect the daily use of the measuring tape component 1. When the spacing of the steel bar 3 is being checked, the anti-deviation auxiliary component 2 is manually flipped downwards by 180 degrees. At this time, the concave stop block 203 is vertically downwards and is fitted onto the outside of the measuring tape 102.

[0029] Then, as with traditional measurement methods, the measuring tape is hooked onto the outside of one reinforcing bar 3 using hook 103. The measuring tape casing 101 is then pulled to the vicinity of another reinforcing bar 3, and the concave stop 203 is moved down to one side of the other reinforcing bar 3. The pull on the measuring tape casing 101 is then slowly released, causing the measuring tape strip 102 to rewind. Finally, the concave stop 203 is brought into close contact with the outside of the other reinforcing bar 3 (e.g., ...). Figure 2 At this time, since the concave stop 203 is horizontally attached to the outside of a steel bar 3, the tape measure 102 can be effectively prevented from shifting, thus effectively improving the detection accuracy.

[0030] It should be noted that the scale of the measuring tape 102 corresponding to the upper edge of the concave stop 203 is the total length, and the spacing is (total length - diameter of the steel bar) ÷ number of steel bars.

[0031] Please refer to this carefully. Figures 1-4 The concave stop 203 has a notch 204 at the top center, and the width of the notch 204 is smaller than the width of the measuring tape 102.

[0032] The inner wall width of the concave stop 203 is greater than the width of the measuring tape 102, and the top horizontal height of the inner wall of the concave stop 203 is higher than the horizontal height of the measuring tape 102.

[0033] In this embodiment: the notch 204 facilitates reading the scale on the measuring tape 102. In addition, the inner wall of the concave stop 203 does not contact the measuring tape 102, so that the two do not interfere with each other.

[0034] Please refer to this carefully. Figures 1-4 The connecting seat 104 and the L-shaped storage groove 105 are integrally formed on the outside of the measuring tape shell 101 by injection molding process. The convex block 201, the connecting pin 202, and the concave stop block 203 are integrally formed by injection molding process.

[0035] In this embodiment, the connector 104, the L-shaped storage slot 105 and the measuring tape shell 101 are integrally formed by injection molding, which is the same as the existing measuring tape shell production process. This makes it easy to improve and produce based on existing equipment. The production cost of the anti-deviation auxiliary component 2 is controllable, making it easy to promote and produce.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
