Description
Technical Field
[0001] This utility model relates to the field of building engineering quality inspection technology, specifically to an adjustable beam formwork width inspection device. Background Technology
[0002] During construction, the quality of carpentry formwork directly affects the overall appearance and cross-sectional dimensions of the structure after demolding. In beam and slab formwork, construction workers and quality inspectors often focus only on the quality of wall, column, and slab formwork, neglecting to check the dimensions of the beams. Currently, in the construction industry, quality inspectors rely heavily on measuring tapes to check beam formwork dimensions. However, measuring the cross-sectional width of beams requires bending, making it difficult to keep the tape level, leading to errors. Furthermore, bending the tape requires multiple adjustments, which is inconvenient and directly affects the accuracy of beam cross-sectional width measurements. Utility Model Content

[0010] According to the above technical solution, a main scale is provided on the main scale body, and its scale range is 0~a.
[0011] According to the above technical solution, the size range of the secondary scale is 0~c, and the secondary scale gradually decreases from the main scale body to the second mating surface; the known length of the main scale is d.
[0012] According to the above technical solution, a sliding cavity is provided inside the main scale body, and a through groove is provided at the top of the sliding cavity. The sliding cavity has an outlet on the side away from the first mating surface. The size of the sliding cavity matches the size of the secondary scale body, and the secondary scale body slides inside the sliding cavity. The sliding adjustment component passes through the through groove and is connected between the main scale body and the secondary scale body.

[0032] Reference Figures 1-3 As shown, this utility model provides an adjustable beam formwork width inspection device, which is applied to beam formwork.
[0033] Example 1
[0034] like Figure 1 As shown, the casting cavity within the beam formwork includes a first side and a second side arranged opposite to each other, the first side and the second side fitting against the two sides of the beam in the thickness direction. (Including...)
[0035] The main scale body 1 has a first contact surface 1-1 on one side that is in contact with the first side of the beam body;
[0036] The secondary ruler body 2 has a second contact surface 2-1 on one side that fits against the second side of the beam body, and the first contact surface and the second contact surface are parallel; the other side of the secondary ruler body is provided on the other side of the main ruler body in a way that allows only sliding connection; the secondary ruler body is provided with a secondary scale 3, and the line where the secondary scale is located is perpendicular to the first contact surface.
[0037] Sliding adjustment component 4 is connected to the main scale body and the auxiliary scale body; the length of the auxiliary scale body extending out of the main scale body is controlled by the sliding adjustment component.
[0038] In this embodiment, the main ruler and the secondary ruler are slidably connected via a sliding adjustment assembly, allowing the extension of the secondary ruler beyond the main ruler to be adjusted according to the spacing between the beam templates. The inspection device is placed inside the beam template, with the first contact surface of the main ruler contacting the inner wall of one side of the beam template, and the second contact surface of the secondary ruler contacting the inner wall of the other side of the beam template. By reading the secondary scale on the secondary ruler, the distance between the inner walls of the two sides of the beam template can be obtained, thus determining the width of the beam.
[0039] Example 2
[0040] like Figure 1 As shown, based on Example 1, the size range of the secondary scale is a~b, and the secondary scale gradually decreases from the main scale body to the second mating surface; as shown in the figure, the range of the secondary scale is 15cm~30cm, and the scale changes from 30cm to 15cm from the main scale body to the second mating surface; the scale reading at the junction of the main scale body and the secondary scale body represents the sum of the length of the main scale body and the length of the secondary scale body extending out of the main scale body.
[0041] Since the auxiliary ruler is slidably connected to the main ruler, when the auxiliary ruler is completely contained within the main ruler, the length of the main ruler is the minimum width of the beam template that the inspection device described in this application can measure, that is, the length of the main ruler is the minimum scale a corresponding to the auxiliary scale; when the auxiliary ruler extends as far as possible beyond the main ruler, the sum of the maximum inspection length of the auxiliary ruler and the length of the main ruler is the maximum width of the beam template that the inspection device described in this application can measure, that is, the minimum scale b corresponding to the minimum scale b of the auxiliary scale.
[0042] Example 3
[0043] like Figure 2 As shown, based on Embodiment 2, to facilitate the measurement of other components by the main scale body and improve the versatility of the inspection device, a main scale 5 is provided on the main scale body, with a scale range of 0~a. As shown in the figure, the secondary scale ranges from 0cm to 15cm, and the scale changes from 0cm to 15cm from the first contact surface to the secondary scale body. Preferably, the main scale and the secondary scale are on the same straight line.
[0044] Example 4
[0045] Based on Example 1, and differing from the scale settings in Examples 2 and 3, another scale setting is provided, where the sub-scale size ranges from 0 to c, and the sub-scale gradually decreases from the main scale body to the second contact surface; the known length of the main scale is d. In this example, the measurement result is the sum of the known length d of the main scale and the reading value of the sub-scale.
[0046] The structures of Example 4 and Example 2 are similar, but the difference is that in Example 2, the reading of the sub-scale is the beam width measurement structure; in Example 4, the sum of the known length of the main scale and the reading of the sub-scale is the beam width measurement structure.
[0047] Based on implementations 1-4, the auxiliary scale body is connected to the main scale body in a sliding connection manner via a groove or guide rail; a preferred and specific sliding form of the auxiliary scale body on the main scale body is provided, wherein a sliding cavity is provided in the main scale body, a through groove 6 is provided at the top of the sliding cavity, and an outlet is provided on the side of the sliding cavity away from the first contact surface; the size of the sliding cavity matches the size of the auxiliary scale body, and the auxiliary scale body slides in the sliding cavity; a sliding adjustment component passes through the through groove and is connected between the main scale body and the auxiliary scale body.
[0048] In this embodiment, the first contact surface of the main scale body is in contact with the first side of the beam template to be measured. After the secondary scale body is slid out of the sliding cavity, when the second contact surface of the secondary scale body is in contact with the second side of the beam template to be measured, the relative position between the main scale body and the secondary scale body is fixed by the sliding adjustment component, and then the scale reading of the secondary scale body is read.
[0049] In the above embodiment, the sliding adjustment component uses a fastening bolt, and a threaded hole is provided at the end of the main scale body located in the through groove and close to the secondary scale body; after the fastening bolt is tightened to the threaded hole, the fastening bolt abuts against the secondary scale body.
[0050] In the above embodiments, both the main scale body and the auxiliary scale body preferably adopt a rectangular plate structure, and the materials used, such as wood, plastic, aluminum, and stainless steel, can be selected according to the materials available at the construction site, or flexibly customized. A rectangular cavity is provided within the main scale body as a sliding cavity; anti-slip layers, such as anti-slip mats, are provided on both the first and second contact surfaces. The materials used, such as wood, plastic, aluminum, and stainless steel, can be selected according to the materials available at the construction site, or flexibly customized.
[0051] Preferably, an anti-slip strip 7 is attached to the bottom of the sliding cavity. The anti-slip strip increases the damping force between the main scale body and the auxiliary scale body, preventing the auxiliary scale body from shaking within the main scale body due to vibrations during operation.
[0052] Preferably, to facilitate adjustment of the relative position between the main scale body and the auxiliary scale body, a gripping hole 8 is provided on both the main scale body and the auxiliary scale body, allowing the operator's hand to be placed inside the gripping hole for operation. The size of the gripping hole can be flexibly adjusted to ensure the user's gripping comfort.
[0053] Preferably, to prevent the main scale from shaking during the adjustment of the relative position between the main scale and the secondary scale, which would affect the measurement accuracy, a detachable support plate is fixedly installed at the bottom of the main scale. The bottom of the support plate has an anti-slip surface. Support plates of various specifications are provided according to the relative position between the bottom template and the side template of the beam. The support plate is fixedly installed at the bottom of the main scale. Through the combined action of the support plate and the first contact surface, the stability of the main scale within the beam template is improved, thereby improving the measurement accuracy.
[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
