Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a device for detecting the surface flatness of a frame structure. Background Technology

[0002] In existing technologies, some devices or equipment need to be installed within door frame structures, requiring surface flatness testing of the door frame structure before installation. Traditional manual inspection methods use straightedges or levels, which are problematic in two ways: firstly, they are difficult to observe when measuring the top surface; secondly, when encountering frame structures with large spans, structural deflection or construction errors can cause localized bulges / depressions in the central area of ​​the top surface compared to the edges. Traditional straightedge or level methods cannot quickly and accurately detect the flatness of the top surface, affecting subsequent construction progress or quality. The traditional manual inspection of frame structure surface flatness suffers from low efficiency, especially in large-span frame structures where anomalies are prone to appear in the central area of ​​the top surface, and the inability of traditional straightedge or level methods to quickly and accurately detect flatness. Utility Model Content

[0005] Furthermore, each fixing mechanism also includes a spacing adjustment rod, which is rotatably connected to two clamping parts, and at least one clamping part is threadedly engaged with the spacing adjustment rod.

[0006] Furthermore, the testing mechanism also includes a tightening screw, which passes through the positioning part and is threaded into the tightening part.

[0025] The embodiments of this utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the utility model, and not all embodiments.

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0028] like Figures 1 to 6 The diagram illustrates an embodiment of the frame structure surface flatness detection device of this utility model. It includes a connecting body; multiple fixing mechanisms, each including two opposing clamping parts 5 connected to the connecting body, at least one clamping part 5 being slidably connected to the connecting body to clamp the frame structure; and a detection mechanism including a positioning part 6 and a tightening part 7. The positioning part 6 is slidably connected to the connecting body to adjust the detection area, and the tightening part 7 has a displacement measuring structure 8 and is slidably connected to the positioning part 6. The tightening part 7 can contact the surface to be detected in different detection areas and detect the flatness of the surface to be detected through the displacement measuring structure 8. Preferably, the connecting body can be formed by interconnecting square tubes with grooves.

[0029] In this embodiment, the surface flatness detection device for frame structures can be fixed to frame structures of different sizes via multiple movable clamping parts 5. The movable tightening part 7 measures multiple detection areas. By comparing the relative offset of the tightening part 7 in different detection areas along the direction perpendicular to the surface to be detected, the flatness of the surface to be detected can be confirmed. It can also accurately measure the deviation at points with bulges or depressions to facilitate grinding and leveling by operators. This embodiment can particularly improve the efficiency and quality of flatness detection of the top surface of frame structures. It can also be extended to the flatness detection of the sides or bottom surfaces. It is applicable to frame structures of various sizes, easy to operate, flexible to use, accurate in detection, and easy to promote and apply.

[0030] In different embodiments, the displacement measuring structure 8 can be a first comparison member or a scale line provided on the clamping part 7. When the displacement measuring structure 8 is a scale line provided on the clamping part 7, the relative displacement of the clamping part 7 in different detection areas along the direction perpendicular to the surface to be detected can be measured by the scale change corresponding to the fixed position of the positioning part 6. That is, the extension of the clamping part 7 relative to the positioning part 6 can be directly measured by the scale line provided on the clamping part 7, such as detecting the flatness of the frame structure surface by the scale change corresponding to the top of the positioning part 6. In this embodiment, the displacement measuring structure 8 is a first comparison member connected to the clamping part 7. The first comparison member is perpendicularly connected to the clamping part 7. The first comparison member is preferably block-shaped and has a reference reference structure 15 corresponding to the clamping part. The reference structure 15 can be used as a comparison reference for the moving distance of the first comparison component. In this embodiment, the reference structure 15 is a reference scale line set on the clamping part 5. The auxiliary comparison component is placed on the first comparison component, and the end of the auxiliary comparison component away from the first comparison component corresponds to a certain scale of the reference scale line. The flatness is detected by observing the corresponding scale change when the tightening part 7 abuts against the surface to be tested in different detection areas. The auxiliary comparison component is selected as a plate-shaped component of appropriate length to fit against the surface of the first comparison component. In another embodiment, the reference structure 15 can be a second comparison component and is perpendicularly connected to the clamping part 5. Preferably, the second comparison component is block-shaped. The tightening part 7 abuts against different detection areas of the surface to be tested, and the relative distance between the first comparison component and the second comparison component along the direction perpendicular to the surface to be tested is measured and recorded. The results of multiple measurements are compared and the flatness is detected by the difference to see if it meets the standard requirements. It should be understood that the shape of the first or second comparison component is not limited in this application, and can be designed based on the general technical knowledge of those skilled in the art, as long as it meets the requirement of being able to perform displacement measurement of the clamping part 7.

[0031] In this embodiment, each fixing mechanism further includes a spacing adjustment rod 9, which is rotatably connected to two clamping parts 5, and at least one clamping part 5 is threadedly engaged with the spacing adjustment rod 9. Preferably, the spacing adjustment rod 9 is provided with a spacing adjustment handle 10, and in this embodiment, the spacing adjustment handle 10 is wheel-shaped and connected to the end of the adjustment rod 9.

[0032] In this embodiment, the detection mechanism further includes a tightening screw 11, which passes through the positioning part 6 and is threadedly engaged with the tightening part 7. Preferably, the tightening screw 11 is provided with a tightening adjustment handle 12, which is wheel-shaped and connected to the end of the tightening screw 11. The positioning part 6 has a movable groove for slidingly mounting the tightening part 7. The cross-section of the movable groove is non-circular, such as a square or triangular groove, which restricts the rotation of the tightening part 7. The shape of the tightening part 7 is adapted to the movable groove. When the tightening screw 11 is rotated, the movable groove restricts the rotation of the tightening part 7, and the tightening part 7 is controlled by the tightening screw 11 to move along the length direction of the movable groove.

[0033] In this embodiment, a linkage mechanism 13 is also included. Multiple detection mechanisms are included, each corresponding to a fixed mechanism. The linkage mechanism 13 includes an inner rod and an outer rod that slide and fit together. The inner and outer rods are connected to corresponding positioning parts 6. The linkage mechanism 13 enables synchronous, unidirectional displacement of multiple detection mechanisms, requiring only the movement of a single detection mechanism, thus improving the efficiency of multi-point measurement by a single person. The linkage mechanism 13 uses a combination of mutually fitted and detachably connected inner and outer rods. When combined, it ensures that the relative positions of the corresponding multiple detection mechanisms are fixed along the length of the second support 3. When disassembled, it can meet individual detection needs, and the lengths of the inner and outer rods can be adjusted according to construction requirements.

[0034] In this embodiment, at least a portion of the clamping part 5 has a limiting structure 14 to abut against the test surface of the frame structure. The limiting structure 14 is in the shape of a boss. In this embodiment, by using the limiting structure 14 to abut against the test surface, it can be ensured that when the surface flatness of the frame structure is good, the distance between the positioning part and the test surface at different test areas is within the standard range.

[0035] In this embodiment, the connecting body is an adjustable rectangular frame, which includes two parallel first supports 1 and multiple second supports 3 vertically disposed between the two first supports 1. The first supports 1 and the second supports 3 are slidably connected, and the clamping part 5 and the positioning part 6 are respectively connected to the corresponding second supports 3. Preferably, the two first supports 1 have a first groove 2 on opposite sides, and the two ends of the second supports 3 are slidably disposed in the corresponding first groove 2. The second supports 3 are provided with a second groove 4, and the positioning part 6 and the slidable clamping part 5 are both provided with sliders 61 to be slidably disposed in the corresponding second groove 4. The second groove 4 can restrict the rotation of the clamping part 5, so when the spacing adjustment rod 9 rotates, the clamping part 5 that is threadedly engaged with it is driven to slide along the length direction of the second support 3. When both clamping parts 5 in each fixing mechanism are threadedly connected to the spacing adjustment rod 9, the threads of the two clamping parts 5 rotate in opposite directions, and rotating the spacing adjustment rod 9 can drive the two clamping parts 5 to move towards or away from each other.

[0036] In this embodiment, a fitting 16 is also included, which is detachably connected to the tightening part 7. Preferably, the fitting 16 has a movable groove. Multiple tightening parts 7 are movably disposed in the movable groove. The fitting 16 can be manufactured according to the size requirements of the surface to be tested. Multiple tightening parts 7 contact the surface to be tested through the same fitting 13 to perform large-area flatness testing.

[0037] The method of using this utility model includes the following steps:

[0038] Multiple clamping parts 5 are symmetrically fixed to the frame structure. Specifically, the limiting structure 14 of a group of clamping parts 5 is attached to the surface to be tested of the frame structure. The spacing adjustment rod 9 is rotated by the spacing adjustment rod 10 to reduce the spacing between the relatively set clamping parts 5, so that multiple clamping parts 5 are clamped on both sides of the surface to be tested of the frame structure. According to the length of the surface to be tested, the corresponding second bracket 3 is moved along the length direction of the first bracket 1. At this time, the corresponding detection mechanism is driven to move synchronously. The two detection mechanisms move closer or further away from each other and the extension length of the corresponding linkage mechanism 13 is adjusted synchronously. After the spacing between the adjacent fixing mechanisms is adjusted, the remaining clamping parts 5 are fixed to the frame structure by the corresponding spacing adjustment rod 9.

[0039] One or more clamping parts 7 are sequentially pressed against different detection areas of the surface to be tested. The relative offset of the clamping parts 7 in different detection areas along the direction perpendicular to the surface to be tested is compared to detect the flatness. Specifically, the positioning part 6 is moved along the length direction of the second bracket 3 to the predetermined detection area, and the linkage mechanism 13 causes the corresponding multiple positioning parts 6 to move synchronously and in the same direction. The multiple positioning parts 6 move together to the predetermined detection area for multi-point detection. The clamping screw 11 is rotated to make the clamping part 7 press against the surface to be tested, and the corresponding measurement scale is recorded. The clamping part 7 is moved along the length direction of the second bracket 3, or the corresponding clamping part 7 is moved along the length direction of the first bracket 1 through the second bracket 3. Measurements are recorded and compared in multiple detection areas to confirm the flatness.

[0040] In addition to point-based testing where multiple clamping parts 7 directly contact the surface to be tested, this embodiment also allows multiple clamping parts 7 to contact the surface to be tested via accessory 16 for preliminary flatness testing over a large area. When the middle of accessory 16 contacts the protrusion of the surface to be tested and one end of accessory 16 abuts against the surface to be tested, the other end of accessory 16 cannot contact the surface to be tested and is tilted. At this time, the multiple clamping parts 7 that contact both ends of accessory 16 have a positional deviation along the direction perpendicular to the surface to be tested. Accessory 16 can be used to quickly detect whether the flatness meets the requirements.

[0041] When an abnormality is found on the surface of the frame structure, the abnormal area is marked for grinding or leveling.

[0042] This embodiment determines the flatness of the frame structure surface based on the distance deviation of the clamping part 7 in different detection areas along the direction perpendicular to the surface to be detected. A quick preliminary inspection can be performed using accessory 16, or a precise point inspection can be performed by direct contact between the clamping part 7 and the surface to be detected. Installation is convenient; the adjustable rectangular connecting body allows for rapid inspection in two mutually perpendicular directions, and a linkage mechanism enables coordinated operation. The adjustable fixing mechanism is suitable for frame structures of different sizes, avoiding continuous hand-held operation, simplifying the top surface flatness inspection process, and improving inspection efficiency and quality.

[0043] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
