Description

Technical Field

[0001] The invention relates to the technical field of dimension measuring equipment, and in particular to a device for measuring dimension of construction cost of a building project. Background Art

[0002] The primary task of construction project cost management in the construction process is cost control. Through reasonable planning and management of the purchase of construction materials, the rental of construction equipment, and the salary of construction personnel, the construction cost can be effectively reduced and the economic benefits can be improved. In the construction of construction projects, square tubes are often used to make key structural components such as steel structure beams and columns, industrial equipment frames, and overhead pipelines.

[0003] Square tube is a name for square tubes, that is, steel tubes with equal sides. It is made by rolling steel strips through processing. It is a hollow square cross-section light thin-walled steel tube, also known as steel cold-bent profiles. Square tubes can be made of a variety of materials, but most are steel tubes. Square tubes can be used to construct frame structures of houses, factories, warehouses, bridges and high-rise buildings, providing stable and reliable support. At the same time, they can also be used as external covering materials for buildings.

[0004] During the actual construction process, the other pipe needs to be temporarily cut to meet the construction needs, and the cutting size needs to be measured by measuring equipment.

[0005] When measuring the size of existing steel pipes, a measuring ruler is usually stretched from one end to the other end for detection. The stretched measuring ruler cannot ensure that it remains parallel to the central axis of the square pipe. Even if it is manually adjusted after the stretching is completed, there will be position deviations, resulting in inaccurate results when measuring the length of the square pipe using the measuring ruler. In addition, the existing size measuring device cannot promptly detect whether there are depressions on the surface of the square pipe when measuring the length of the square pipe, which has defects in the selection of qualified square pipes. Summary of the invention

[0006] The purpose of the present invention is to solve the problem of inaccurate measurement results in traditional square tube size measurement and to propose a construction engineering cost construction size measurement device.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technologies: a construction project cost construction dimension measuring device, including a frame, an adjusting mechanism and a measuring mechanism, the frame including a horizontal plate and two limit plates slidably installed inside the horizontal plate, the limit plates are controlled by the adjusting mechanism to achieve position adjustment; it also includes a clamping assembly assembled at the open end of the limit plate, the clamping assembly includes clamping parts rotatably installed at the open ends of the limit plates respectively; the two clamping parts are diagonally clamped at the two diagonals of the square tube, so that the measuring ruler included in the measuring mechanism slides parallel to the central axis of the square tube for length measurement, the clamping parts are rotated near the middle and outer edges of the first rollers, and the second roller is elastically connected between the two first rollers, and the elastic connection of the second roller reflects whether the surface of the square tube is flat; the two clamping parts are spliced ​​into a horizontal shape so that the grinding groove opened at the bottom grinds the cross section of the square tube, and the two clamping parts are flipped to the outside of the limit plate so that the limit plates close to each other can measure the width, height and thickness of the square tube.

A limit slot is provided on the engaging piece on one side of the slider, and a limit rod penetrating the limit slot is fixedly installed on one side of the slider.

[0012] As a further description of the above-mentioned technology, a construction engineering cost construction dimension measuring device:

[0018] In summary, due to the use of the above-mentioned technology, a construction engineering cost construction dimension measuring device has the following beneficial effects:

[0019] By making one side of the square tube contact the ground, using the adjustment mechanism to clamp the clamping parts in the clamping assembly on both sides of the square tube, placing one end of the measuring ruler on the end face of the square tube size, and sliding the entire device, the measuring ruler can be kept sliding in a direction parallel to the central axis of the square tube, so that the measuring ruler will not be offset in the process of measuring the square tube, ensuring accurate measurement of the square tube size. During the movement of the clamping part, the elastically mounted second roller on it is used to slide against the edge of the square tube.

In addition, by changing the positions of the two clamping parts, the size measuring device can have the function of grinding the end face of the square tube. At the same time, the clamping part is flipped to the outside of the limit plate so that the limit plates close to each other can measure the width, height and thickness of the square tube, further expanding the use range of the measuring device and improving the measurement accuracy of the measuring device.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a construction engineering cost construction dimension measuring device. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 7 As shown, the present invention provides: a construction engineering cost construction dimension measuring device, comprising a frame 10, an adjustment mechanism 20 and a measuring mechanism 30, the frame 10 comprises a horizontal plate 11, and two limit plates 12 slidably mounted inside the horizontal plate 11, the limit plates 12 are controlled by the adjustment mechanism 20 to achieve position adjustment; the adjustment mechanism 20 comprises a double-headed screw 21 rotatably mounted inside the horizontal plate 11, the limit plates 12 are threadedly connected with the double-headed screw 21, and the limit plates 12 are slidably mounted inside the horizontal plate 11. A long groove is provided at the bottom of the horizontal plate 11, so that the limit plates 12 can slide at the bottom of the horizontal plate 11 under normal conditions; wherein the double-headed screw 21 is a rod-shaped structure with two sections of threads in opposite directions on the outer wall in the prior art, and since the double-headed screw 21 is threadedly connected with the limit plates 12, the rotation of the double-headed screw 21 will generate an axial force on the limit plates 12, so that the two limit plates 12 move closer to or away from each other, thereby achieving the distance adjustment between the two limit plates 12.

[0035] like Figure 1-7As shown, it also includes a clamping assembly 40 assembled at the open end of the limit plate 12, and the clamping assembly 40 includes a clamping member 42 rotatably installed at the open end of the limit plate 12; the limit plate 12 is a U-shaped structure, and the clamping member 42 is rotatably installed at the U-shaped open end of the limit plate 12 through a rotating shaft; when the two clamping members 42 are diagonally clamped at the two diagonals of the square tube, the measuring ruler 33 included in the measuring mechanism 30 slides parallel to the central axis of the square tube to measure the length, so that the measuring ruler 33 will not be positionally offset during the measurement of the square tube, thereby ensuring accurate measurement of the square tube size.

[0036] In further detail, the first roller 41a is rotatably arranged near the middle and outer edge of the engaging member 42, and the second roller 41 is elastically connected between the two first rollers 41a, and the elastic connection of the second roller 41 reflects whether the surface of the square tube is flat; wherein, the clamping assembly 40 also includes a plurality of grooves 45 opened on the engaging member 42, and the first roller 41a and the second roller 41 are rotatably installed in the grooves 45, and the first roller 41a is installed on the inner wall of the groove 45 through a rotating shaft, and the roller is made of a metal material with a smooth surface, and the function of the roller can reduce the friction force of the measuring device moving between the square tubes, and facilitate the sliding of the roller; the first roller 41a on the engaging member 42 plays a role of limiting, so that the engaging member 42 can be installed in a posture parallel to the edge of the square tube.

[0037] In further detail, a pair of slide grooves are provided in the groove 45, and a slider 48 is slidably installed in the slide groove, and the second roller 41 rotates between two opposite sliders 48. A limit spring 47 is fixedly installed on one side of the slider 48, and the limit spring 47 is fixedly connected to the inner wall of the slide groove at one end away from the slider 48. The slide groove provides a sliding space for the slider 48, and the second roller 41 is rotatably installed between the two sliders 48 through a rotating shaft, so the slider 48 slides inside the slide groove, which can cause the second roller 41 to shrink; wherein, the elastic force provided by the limit spring 47 can keep the slider 48 in a tendency to reset, so that the second roller 41 always fits the edge of the square tube; therefore, when the engaging member 42 slides along the square tube, the first roller 41a and the second roller 41 slide simultaneously in contact with the surface of the square tube.

[0038] In further detail, a limiting groove 43 is provided on the engaging member 42 at one side of the slider 48, and a limiting rod 46 penetrating the limiting groove 43 is fixedly installed on one side of the slider 48. The limiting groove 43 provides a sliding space for the limiting rod 46. In the initial state, a plurality of limiting rods 46 are kept in a straight line. When the engaging member 42 slides on the surface of the square tube and a depression occurs, the second roller 41 will be pressed toward the depression under the action of the limiting spring 47, so that the roller at the depression is not in a straight line with the rollers at other positions. At this time, the roller at the depression will also drive the limiting rod 46 to move, so that the limiting rod 46 on the slider 48 next to the roller at the depression and other limiting rods 46 are not in the same straight line, so that the engaging member 42 can determine whether the surface of the square tube has a depression by observing the position change of the limiting rod 46 during the sliding process along the square tube, and support the selection of qualified square tubes.

[0039] like Figure 1-4 As shown, two engaging members 42 are spliced ​​into a horizontal shape so that the grinding groove 44 opened at the bottom is ground flat to the cross section of the other tube. A protruding block is fixed at one end of one engaging member 42, and a concave groove matching the protruding block is opened at one end of the other engaging member 42. Please refer to Figure 2 When the protruding block is plugged into the recessed groove, the two engaging members 42 can be spliced ​​together (such as Figure 4 As shown), the whole measuring device is ensured to be in a stable state. When the two engaging members 42 are spliced ​​together, the friction between the two members and the square tube can be increased, so that the engaging member 42 can grind the cross section of the square tube smoothly. The measuring device is held by hand, so that the grinding groove 44 on one side of the engaging member 42 rubs against the end face of the square tube, so that the end face of the square tube can become smooth, so that the measuring ruler 33 can be guaranteed to be flat when it is hung on the end face of the square tube, thereby reducing the error generated during the measurement process of the measuring ruler 33. Since the square tube is cut by a cutting knife during use, the end face of the square tube after cutting will be relatively rough, and it can bring convenience to the use of the square tube after grinding.

[0040] like Figure 1-4 As shown, the frame 10 also includes a scale groove 13 opened on the surface of the horizontal plate 11. The two engaging members 42 are flipped to the outside of the limit plate 12 so that the limit plates 12 close to each other can measure the width, height and thickness of the opposite tube. The scale groove 13 is more precise than the smallest unit of the scale line on the surface of the measuring ruler 33, and can measure the size of narrow objects; therefore, when the two engaging members 42 are flipped to the outside of the limit plate 12, the measuring tool is dependent on the two limit plates 12 (such as Figure 5 As shown in the figure, by adjusting the distance between the two limit plates 12 and observing the scale groove 13, the sizes of the two narrower objects to be measured can be obtained; thus, the two limit plates 12 can measure the thickness, width and height of the square tube. This further expands the use range of the measuring instrument and improves the measuring accuracy of the measuring instrument.

[0041] like Figure 1-2 As shown, the measuring mechanism 30 includes a housing 31 fixedly mounted on the horizontal plate 11, a spring spring 32 is fixed inside the housing 31, and one end of the spring spring 32 away from the housing 31 is fixedly connected to a measuring ruler 33. The elastic force provided by the spring spring 32 can keep the measuring ruler 33 in a reset state, thereby facilitating the winding of the measuring ruler 33. The structure composed of the spring spring 32, the housing 31 and the measuring ruler 33 is the same as the principle structure of a tape measure in the prior art.

[0042] like Figure 1-2 As shown, the open end of the limit plate 12 is slidably equipped with a cleaning assembly 50, and the cleaning assembly 50 includes a guide plate 51 that elastically slides on the open end of the limit plate 12, and a cleaning strip 52 is fixed to the bottom of the guide plate 51, and the guide plate 51 is T-shaped; the bottom of the guide plate 51 is an arc-shaped chamfered structure, and a spring is fixed between the upper end of the guide plate 51 and the limit plate 12, which can keep the lower end of the guide plate 51 in contact with the engaging member 42. Therefore, during the flipping process of the engaging member 42, the grinding groove 44 can contact the cleaning strip 52 to achieve cleaning of the grinding groove 44; when the engaging member 42 cannot rotate, the guide plate 51 can also be moved manually to avoid jamming between the engaging member 42 and the guide plate 51. Thereby reducing the dust accumulation inside the grinding groove 44; in addition, the elastic force provided by the spring keeps the guide plate 51 in the tendency to reset, and can squeeze the engaging member 42 placed at the open end of the limit plate 12 so that it can be temporarily fixed, making it more convenient to move the limit plate 12 to measure the thickness, width and height of the square tube.

[0043] Working principle: When measuring the length of a square tube, one side of the square tube is brought into contact with the ground, and the clamping member 42 in the clamping assembly 40 is clamped on both sides of the square tube by using the adjustment mechanism 20. Rotating the double-headed screw 21 will generate an axial force on the limit plate 12, so that the two limit plates 12 move closer to or farther from each other, thereby adjusting the distance between the two limit plates 12, and making the two clamping members 42 firmly fixed on both sides of the square tube; placing one end of the measuring ruler 33 on the end face of the square tube size, and sliding the entire device, so that the measuring ruler 33 can keep sliding in a direction parallel to the central axis of the square tube, and the length of the square tube can be measured;

[0044] When the engaging member 42 slides on the surface of the square tube and a depression appears, the second roller 41 will be squeezed toward the depression under the action of the limit spring 47, so that the roller located at the depression is not in a straight line with the rollers at other positions. At this time, the roller located at the depression will also drive the limit rod 46 to move through the slider 48, so that the limit rod 46 on the sliders 48 on both sides of the roller at the depression is not in the same straight line with the other limit rods 46. Therefore, when the engaging member 42 slides along the square tube, it is possible to determine whether the surface of the square tube has a depression by observing the position change of the limit rod 46, thereby providing support for the selection of qualified square tubes.

[0045] When the two engaging members 42 are turned over to the outside of the limiting plate 12, the measuring tool is dependent on the two limiting plates 12 (such as Figure 5 As shown), by adjusting the distance between the two limit plates 12, the sizes of the two narrower objects to be measured can be obtained by observing the scale grooves 13; thereby, the two limit plates 12 can measure the thickness, width and height of the square tube.

[0046] When the protruding block is plugged into the recessed groove, the two engaging members 42 can be spliced ​​together (such as Figure 4 As shown), the entire measuring device is ensured to be in a stable state. When the two engaging members 42 are spliced ​​together, the friction between the two engaging members 42 and the square tube can be increased, making it easier for the engaging members 42 to grind the cross section of the square tube.

[0047] During the flipping process of the engaging member 42, the grinding groove 44 can contact the cleaning strip 52 to clean the grinding groove 44. The elastic force provided by the spring keeps the guide plate 51 in the tendency to return to the original position, and the engaging member 42 placed at the open end of the limiting plate 12 can be squeezed to be temporarily fixed, so that it is convenient to move the limiting plate 12 to measure the thickness, width and height of the square tube.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a construction project cost construction dimension measuring device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
