Description

Technical Field

[0001] The utility model relates to the technical field of building measurement, in particular to a measuring tool suitable for the installation and calibration of precast window forms. Background Technique

[0002] A precast window opening refers to a window opening prefabricated during the building construction process, which is a technological opening reserved by construction workers for subsequent window form installation. The precast window opening can be made by means of templates, molds, etc. to ensure the accuracy of the opening size and position.

[0003] Currently, in most newly built buildings in cities, prefabricated structures are adopted, and corresponding precast window form components are used for installation on the precast window openings. During the installation of precast window forms, construction workers usually use a tape measure for on-site measurement, positioning and other position calibration, and a laser level for surveying verticality, flatness and other geometric calibration. However, during the process of horizontal positioning on the window side and verticality calibration of the window side, construction workers need to repeatedly climb up and down the window sill for elevation measurement. The window opening is close to the outside of the building and is relatively high from the ground, which poses certain safety hazards. The tape measure body is relatively soft, which is prone to errors and has low measurement efficiency.

[0004] In view of the above deficiencies, we need to develop a measuring tool suitable for the installation and calibration of precast window forms to meet the usage requirements of the majority of users. Content of the Utility Model

[0005] In view of the problems of potential safety hazards and easy error caused by using a tape measure and a laser level to measure the window opening during the installation of the existing precast window form, the technical solution adopted by the utility model to solve its technical problems is:

[0006] A measuring tool suitable for the installation and calibration of precast window forms includes a position calibration component and a geometric calibration component for assisting in measuring window opening data. The geometric calibration component is installed on one side of the position calibration component, and calibration scales for assisting calibration are respectively provided on the surfaces of the position calibration component and the geometric calibration component;

[0007] The position calibration component includes a measuring kit and a measuring insert. The measuring kit is provided with a nested inner cavity for the measuring insert to extend into, and the measuring insert can reciprocally slide in the nested inner cavity along the length direction of the measuring kit.

[0008] Furthermore, the geometric calibration component includes a kit sub-scale and an insert sub-scale for assisting in positioning. The kit sub-scale is fixedly connected to the first reference surface of the measuring kit, and the insert sub-scale is fixedly connected to the side of the measuring insert close to the first reference surface. The length of the insert sub-scale is greater than the length of the kit sub-scale.

[0009] Further, the scale lines include quantity scale lines, which are located on the second reference plane of the measurement kit. The second reference plane is adjacent to and perpendicular to the first reference plane. The quantity scale lines extend from the side of the second reference plane close to the first reference plane towards the direction away from the first reference plane.

[0010] Further, the scale lines include first geometric tolerance scale lines and second geometric tolerance scale lines. The first geometric tolerance scale lines are located on the third reference plane of the secondary scale of the kit. The direction of the center of the secondary scale of the kit towards the third reference plane is the same as the direction of the center of the measurement kit towards the second reference plane. The second geometric tolerance scale lines are located on the fourth reference plane of the secondary scale of the insert. The direction of the center of the secondary scale of the insert towards the fourth reference plane is the same as the direction of the center of the measurement kit towards the second reference plane.

[0011] Further, the first geometric tolerance scale lines extend from the side of the third reference plane away from the secondary scale of the insert towards the secondary scale of the insert, and the second geometric tolerance scale lines extend from the side of the fourth reference plane close to the secondary scale of the kit towards the direction away from the secondary scale of the kit.

[0012] Further, the starting point of the first geometric tolerance scale lines is set on the side of the third reference plane close to the first reference plane, and the starting point of the second geometric tolerance scale lines is set on the side of the fourth reference plane close to the first reference plane.

[0013] Further, the central axis of the secondary scale of the kit is perpendicular to the first reference plane, and the central axis of the secondary scale of the insert is perpendicular to the first reference plane.

[0014] Further, the secondary scale of the kit is provided with a fifth reference plane, which is perpendicular to the first reference plane, and the starting point of the quantity scale lines is in the same plane as the fifth reference plane.

[0015] Further, the scale lines are evenly spaced along the length directions of the quantity checking component and the geometric tolerance checking component respectively.

[0016] Further, both the quantity checking component and the geometric tolerance checking component are spliced by rectangular pipe fittings with a hollow thin-wall design, and the cross-sections of the rectangular pipe fittings are all rectangles.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. The measuring tool of the present utility model realizes the telescopic movement relative to the measuring kit by manually operating the sliding of the insert in the nested inner cavity. When used in conjunction with the scale lines, it can achieve the size measurement effect as an alternative to a tape measure. The shape and position verification component is used in conjunction with a laser level and the scale lines for shape and position verification survey. The measuring tool has a rigid characteristic that is not easily bent, ensuring the accuracy of measurement. There is no need for construction workers to climb high for measurement, which is convenient for construction workers to use and carry.

[0019] 2. The present utility model uses rectangular pipe fittings as the material for splicing the measuring tool. Utilizing the characteristics of the rectangle, it restricts the telescopic sliding between the measuring kit and the measuring insert from occurring radial circumferential rotation. Scale lines in the same direction are set on the kit secondary scale and the insert secondary scale. Using a laser level in conjunction with the scale lines on the kit secondary scale and the insert secondary scale can achieve the effect of surveying shape and position deviation, and can measure the data of two positions simultaneously. There is no need for construction workers to climb high for measurement, which is convenient for construction workers to use.

[0020] 3. The kit secondary scale of the present utility model is vertically arranged on the measuring kit, and the insert secondary scale is vertically arranged on the measuring insert, enabling the measuring tool to utilize the right-angle corner at its connection to survey the corner perpendicularity of the prefabricated window opening. There is no need for construction workers to climb high for measurement or go out of the window for inspection, which is convenient for construction workers to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will make a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0028] As Figures 1 to 6As shown in the figure, a measuring tool suitable for the installation and verification of prefabricated window forms includes a position verification component 1200 for assisting in measuring window opening data and a geometric position verification component 3400. The geometric position verification component 3400 is installed on one side of the position verification component 1200. Scale lines for facilitating auxiliary calibration are respectively provided on the surfaces of the position verification component 1200 and the geometric position verification component 3400.

[0029] The position verification component 1200 includes a measuring kit 1 and a measuring insert 2. The measuring kit 1 is provided with a nested inner cavity 11 for the measuring insert 2 to extend into. The measuring insert 2 can reciprocally slide in the nested inner cavity 11 along the length direction of the measuring kit 1.

[0030] Specifically, in some embodiments, the position verification component 1200 is a position verification tool in the measuring tool for measuring data such as distance or length. Position refers to the value obtained by measuring different positions or objects through the tool. The geometric position verification component 3400 is a geometric position verification tool in the measuring tool for measuring data such as perpendicularity, flatness, and inclination. Geometric position refers to the relative position relationship between the outer shapes, shapes, or positions of different objects to be measured through the tool. Scale lines for facilitating auxiliary calibration are respectively provided on the surfaces of the position verification component 1200 and the geometric position verification component 3400. Numbers and marks corresponding to the scale positions are set on the scale lines. When observing the scale, construction workers can know the position of the scale from the corresponding numbers and marks. The scale lines can form multiple scales spaced at intervals in millimeters and are arranged along the length directions of the position verification component 1200 and the geometric position verification component 3400. Construction workers can measure the size and outer shape of the prefabricated window opening through the scale lines on the measuring tool to verify and check the actual size and actual shape of the prefabricated window opening. After collecting the measurement data, construction workers can install the prefabricated window form according to the actual situation. When it is found that the actual size and actual shape of the prefabricated window opening deviate greatly, it can also be repaired and reorganized in time. Both the position verification component 1200 and the geometric position verification component 3400 are made of materials with a certain hardness. These materials are not easy to bend, which is convenient for construction workers to use repeatedly and ensures the accuracy and reliability of the measurement.

[0031] More specifically, the dimension and position checking component 1200 includes a measurement kit 1 and a measurement insert 2. A clearance fit is adopted between the measurement kit 1 and the measurement insert 2. The measurement kit 1 is provided with a nested inner cavity 11 with a hollow design. One end of the measurement insert 2 extends into the nested inner cavity 11 and reciprocates and slides relative to the measurement kit 1 along the length direction of the measurement kit 1, so that construction workers can measure prefabricated window openings of different sizes. The form and position checking component 3400 is respectively installed on the sides of the measurement kit 1 and the measurement insert 2 in the same direction. During use, the construction workers respectively place the form and position checking component 3400 on the side window sills of the prefabricated window opening, use a laser level to shine light on the form and position checking component 3400, and judge the deviation of the window opening in terms of form and position through the position of the light on the scale line, so as to realize form and position measurement and checking. The construction workers only need to place the measuring tool on the prefabricated window opening to use it, without the need for construction workers to climb high for measurement or go out of the window for investigation, which is convenient for construction workers to use and carry.

[0032] As Figures 1 to 6 shown, the form and position checking component 3400 includes a kit sub-scale 3 for auxiliary positioning and an insert sub-scale 4. The kit sub-scale 3 is fixedly connected to the first reference surface 71 of the measurement kit 1, and the insert sub-scale 4 is fixedly connected to the side of the measurement insert 2 close to the first reference surface 71, and the length of the insert sub-scale 4 is greater than the length of the kit sub-scale 3.

[0033] Specifically, in some embodiments, the kit sub-scale 3 is a component of the form and position checking component 3400 installed on the measurement kit 1 for auxiliary investigation and positioning, the insert sub-scale 4 is a component of the form and position checking component 3400 installed on the measurement insert 2 for auxiliary investigation and positioning, the first reference surface 71 is a reference surface provided on the measurement kit 1 for construction workers to determine the positions of the kit sub-scale 3 and the insert sub-scale 4. The kit sub-scale 3 is fixedly connected to the first reference surface 71 of the measurement kit 1 and is located on the side of the first reference surface 71 away from the measurement insert 2. The insert sub-scale 4 is fixedly connected to the side of the measurement insert 2 close to the first reference surface 71 and is located at the end of the measurement insert 2 away from the measurement kit 1. Since the measurement insert 2 extends into the interior of the measurement kit 1, the outer diameter of the measurement insert 2 is smaller than the outer diameter of the measurement kit 1. To ensure that the measurement kit 1 and the measurement insert 2 can maintain a horizontal position when the kit sub-scale 3 and the insert sub-scale 4 are placed on the ground, the difference in the outer surface of the measurement kit 1 and the measurement insert 2 is increased on the length of the insert sub-scale 4, so that the length of the insert sub-scale 4 is greater than the length of the kit sub-scale 3, ensuring the smooth use of the measuring tool. The distance between the kit sub-scale 3 and the insert sub-scale 4 is separated as much as possible to increase the reliability of the measurement data. Through the expansion and contraction between the measurement kit 1 and the measurement insert 2, the kit sub-scale 3 and the insert sub-scale 4 can be placed at different positions on the prefabricated window opening, enabling multi-point measurement and improving the accuracy of the measurement data.

[0034] As Figures 1 to 3As shown, the scale line includes a measurement position scale line 51, and the measurement position scale line 51 is located on the second reference plane 72 of the measurement kit 1. The second reference plane 72 is adjacent to and perpendicular to the first reference plane 71. The measurement position scale line 51 extends from the side of the second reference plane 72 close to the first reference plane 71 in a direction away from the first reference plane 71.

[0035] Specifically, in some embodiments, the measurement position scale line 51 is a reference scale line provided on the measurement kit 1 for construction workers to measure dimensions such as distance, length, wall thickness, and window thickness. The second reference plane 72 is a reference plane on the measurement kit 1 for setting the measurement position scale line 51. The second reference plane 72 is adjacent to and perpendicular to the first reference plane 71, enabling construction workers to see the measurement position scale line 51 when using the kit sub-scale 3 and the insert sub-scale 4, and using a laser level to scan the measurement position scale line 51, facilitating the construction workers to observe the position of the light on the measurement position scale line 51, thereby conveniently judging the measured data. The measurement position scale line 51 extends from the side of the second reference plane 72 close to the first reference plane 71 in a direction away from the first reference plane 71, and the direction of the scale lines of the measurement position scale line 51 conforms to the survey direction when construction workers use the measuring tool.

[0036] More specifically, the scale of the measurement position scale line 51 is provided with measurement position scale lines of different lengths. At positions every 1 millimeter, relatively parallel millimeter measurement position scale lines are used. At positions every 1 centimeter, relatively parallel centimeter measurement position scale lines are used. At positions every 5 centimeters, relatively parallel decimeter measurement position scale lines are used. With such a design, it can enable construction workers to more clearly see the position of the light of the laser level on the measurement position scale line 51, facilitating construction workers to record data.

[0037] As Figures 1 to 3 shown, the scale line includes a first geometric tolerance scale line 52 and a second geometric tolerance scale line 53. The first geometric tolerance scale line 52 is located on the third reference plane 73 of the kit sub-scale 3. The direction of the center of the kit sub-scale 3 towards the third reference plane 73 is the same as the direction of the center of the measurement kit 1 towards the second reference plane 72. The second geometric tolerance scale line 53 is located on the fourth reference plane 74 of the insert sub-scale 4. The direction of the center of the insert sub-scale 4 towards the fourth reference plane 74 is the same as the direction of the center of the measurement kit 1 towards the second reference plane 72.

[0038] Specifically, in some embodiments, the first geometric scale line 52 is a reference scale line provided on the accessory sub-scale 3 for positioning the light ray position of the laser level, the second geometric scale line 53 is a reference scale line provided on the insert sub-scale 4 for positioning the light ray position of the laser level, the third reference plane 73 is the reference plane on the accessory sub-scale 3 for setting the first geometric scale line 52, the fourth reference plane 74 is the reference plane on the insert sub-scale 4 for setting the second geometric scale line 53. The first geometric scale line 52 forms a plurality of scales arranged at intervals in millimeters and is arranged along the length direction of the accessory sub-scale 3. The second geometric scale line 53 forms a plurality of scales arranged at intervals in millimeters and is arranged along the length direction of the insert sub-scale 4. In use, the second reference plane 72, the third reference plane 73, and the fourth reference plane 74 are all on the same side of the measuring tool in the same direction. The construction worker can observe the positions of the light ray of the laser level on the measuring scale line 51, the first geometric scale line 52, and the second geometric scale line 53 together, which is convenient for the construction worker to observe the scales and record data.

[0039] As Figures 1 to 3 shown, the first geometric scale line 52 extends from the side of the third reference plane 73 away from the insert sub-scale 4 towards the insert sub-scale 4, and the second geometric scale line 53 extends from the side of the fourth reference plane 74 close to the accessory sub-scale 3 towards the direction away from the accessory sub-scale 3.

[0040] Specifically, in some embodiments, when using the measuring tool, the construction worker generally holds the measuring accessory 1 with the measuring accessory 1 as the main measuring device, and measures by adjusting the position of the telescopic measuring insert 2 in the measuring accessory 1. Therefore, generally, the measuring accessory 1 is on the side close to the user's body. The first geometric scale line 52 extends from the side of the third reference plane 73 away from the insert sub-scale 4 towards the insert sub-scale 4, and the second geometric scale line 53 extends from the side of the fourth reference plane 74 close to the accessory sub-scale 3 towards the direction away from the accessory sub-scale 3. Therefore, the engraving directions of the first geometric scale line 52 and the second geometric scale line 53 conform to the surveying direction when the construction worker uses the measuring tool;

[0041] More specifically, the scales of the first geometric scale line 52 and the second geometric scale line 53 are provided with geometric scale lines of different lengths. At positions every 1 millimeter, relatively parallel millimeter geometric scale lines are used. At positions every 1 centimeter, relatively parallel centimeter geometric scale lines are used. At positions every 5 centimeters, relatively parallel graduation geometric scale lines are used. With such a design, it can enable the construction worker to more clearly see the positions of the light ray of the laser level on the first geometric scale line 52 and the second geometric scale line 53, which is convenient for the construction worker to record data.

[0042] As Figure 3As shown, the starting point of the first geometric scale line 52 is set on the side of the third reference plane 73 close to the first reference plane 71, and the starting point of the second geometric scale line 53 is set on the side of the fourth reference plane 74 close to the first reference plane 71.

[0043] Specifically, in some embodiments, the starting point b of the first geometric scale line 52 is the starting end for starting to set numbers or marks on the first geometric scale line 52, and the starting point c of the second geometric scale line 53 is the starting end for starting to set numbers or marks on the second geometric scale line 53. The starting point b of the first geometric scale line 52 is located at one end of the accessory sub-scale 3 close to the measuring accessory 1, and the starting point c of the second geometric scale line 53 is located at one end of the insert sub-scale 4 close to the measuring insert 2. With such a design, it is convenient for construction workers to have a reference when calculating the position of the scale line, improving the efficiency of calculating the scale and accelerating the measurement progress.

[0044] As Figure 3 shown, the central axis of the accessory sub-scale 3 is perpendicular to the first reference plane 71, and the central axis of the insert sub-scale 4 is perpendicular to the first reference plane 71.

[0045] Specifically, in some embodiments, the central axis of the accessory sub-scale 3 is the central axis along the length direction of the accessory sub-scale 3, and the central axis of the insert sub-scale 4 is the central axis along the length direction of the insert sub-scale 4. The central axis of the accessory sub-scale 3 is perpendicular to the plane on the side of the measuring accessory 1 facing the accessory sub-scale 3, so that the accessory sub-scale 3 and the measuring accessory 1 form a structure with mutually perpendicular sides. Construction workers can use the right-angled interior angle between the accessory sub-scale 3 and the measuring accessory 1 to survey the perpendicularity of the prefabricated window opening or the angle of the window sill corner, and then record the deviation value. The central axis of the insert sub-scale 4 is perpendicular to the plane on the side of the measuring insert 2 facing the insert sub-scale 4, so that the insert sub-scale 4 and the measuring insert 2 form a structure with mutually perpendicular sides. Construction workers can also use the right-angled interior angle between the insert sub-scale 4 and the measuring insert 2 to survey the perpendicularity of the prefabricated window opening or the angle of the window sill corner. Both sides of the measuring tool can be used, facilitating construction workers to record data.

[0046] As Figures 1 to 3 shown, the accessory sub-scale 3 is provided with a fifth reference plane 75, the fifth reference plane 75 is perpendicular to the first reference plane 71, and the starting point of the measurement scale line 51 is in the same plane as the fifth reference plane 75.

[0047] Specifically, in some embodiments, the fifth reference plane 75 is a reference plane located on the side of the accessory sub-scale 3 facing the insert sub-scale 4 for aligning the starting point of the measurement position scale line 51. The starting point a of the measurement position scale line 51 forms a plurality of scales arranged at intervals in the direction towards the measurement insert 2 from the position of the fifth reference plane 75. The scales of the measurement position scale line 51 are provided with measurement position scale lines of different lengths. At positions spaced 1 millimeter apart, millimeter measurement position scale lines are arranged in a relatively parallel manner. At positions spaced 1 centimeter apart, centimeter measurement position scale lines are arranged in a relatively parallel manner. At positions spaced 5 centimeters apart, decimeter measurement position scale lines are arranged in a relatively parallel manner. With such a design, it is possible to enable construction personnel to more clearly see the position of the light of the laser level on the measurement position scale line 51, facilitating data recording by construction personnel.

[0048] As Figures 1 to 3 shown, the scale lines are uniformly arranged at intervals along the length directions of the measurement position calibration component 1200 and the form and position calibration component 3400.

[0049] Optionally, the cross-section of the measurement position calibration component 1200 and / or the form and position calibration component 3400 can adopt a circular structure or a rectangular structure as the outer structure. Preferably, the cross-section of the measurement position calibration component 1200 adopts a rectangular structure as the outer structure. The rectangular structure has a clearly defined outer side surface, which can prevent the measurement position calibration component 1200 from slipping during use and affecting measurement, facilitating the use of construction personnel.

[0050] Specifically, in some embodiments, the scale lines are arranged around the outer circumference of the measurement position calibration component 1200 and are uniformly arranged at intervals along the length direction of the measurement position calibration component 1200. The scale lines are arranged around the outer circumference of the form and position calibration component 3400 and are uniformly arranged at intervals along the length direction of the form and position calibration component 3400. When the cross-section of the measurement position calibration component 1200 and / or the form and position calibration component 3400 adopts a circular structure, the scale lines are arranged on the outer curved surface of the circular structure. Adopting a circular structure facilitates construction personnel to hold it with their hands to adjust the telescopic distance between the measurement kit 1 and the measurement insert 2. When the cross-section of the measurement position calibration component 1200 and / or the form and position calibration component 3400 adopts a rectangular structure, the scale lines are arranged on each side in the radial direction of the rectangular structure, facilitating construction personnel to observe and record the scale position where the light of the laser level is located from different sides.

[0051] As Figure 2 shown, the measurement position calibration component 1200 and the form and position calibration component 3400 are both assembled by splicing rectangular pipe fittings 6 with a hollow thin-wall design, and the cross-sections of the rectangular pipe fittings 6 are all rectangular.

[0052] Specifically, in some embodiments, the rectangular pipe fitting 6 is a spliced pipe fitting that composes the quantity position calibration component 1200 and the geometric position calibration component 3400. The rectangular pipe fitting 6 is designed with a hollow thin wall. The cross-section of the rectangular pipe fitting 6 is rectangular. The rectangular pipe fitting 6 has an outer side surface with distinct corners, and there is also a rounded transition between each side surface of the rectangular pipe fitting 6. Using the rectangular pipe fitting 6 as a spliced component can prevent the quantity position calibration component 1200 from slipping during use and affecting the measurement, which is convenient for construction workers to use.

[0053] As Figures 1 to 6 shown, the specific implementation manner of Embodiment 1 of the present utility model is as follows:

[0054] During installation, the quantity position scale line 51 is set on the measurement kit 1. The kit secondary scale 3 is welded to the measurement kit 1. The first geometric position scale line 52 is located on the plane of the kit secondary scale 3 facing the quantity position scale line 51. The length direction of the kit secondary scale 3 is perpendicular to the length direction of the measurement kit 1. The insert secondary scale 4 is welded to the measurement insert 2. The second geometric position scale line 53 is located on the plane of the insert secondary scale 4 facing the quantity position scale line 51. The length direction of the insert secondary scale 4 is perpendicular to the length direction of the insert secondary scale 4, and the installation of the measuring tool is completed;

[0055] When measuring the length, the construction worker places the quantity position scale line 51 horizontally between two measured objects, or horizontally on the window sill of the precast window. Pull out or push in the measurement insert 2 with the hand in the nested inner cavity 11 so that the end of the measurement insert 2 away from the measurement kit 1 reaches the position to be measured. Determine the measured value by visual inspection or the light irradiated on the quantity position scale line 51 by a laser level and record it;

[0056] When measuring the flatness, the construction worker places the kit secondary scale 3 and the insert secondary scale 4 naturally on the measured plane. Determine the measured value by the light irradiated on the first geometric position scale line 52 and the second geometric position scale line 53 by a laser level at the same time and record it. Calculate the difference between the values on the first geometric position scale line 52 and the second geometric position scale line 53 to judge the deviation of the flatness;

[0057] When measuring the inclination, the construction worker places the kit secondary scale 3 and the insert secondary scale 4 naturally on the measured plane. Determine the measured value by the light irradiated on the first geometric position scale line 52 and the second geometric position scale line 53 by a laser level at the same time and record it. Calculate the difference between the values on the first geometric position scale line 52 and the second geometric position scale line 53 to judge the deviation of the inclination;

[0058] When measuring the perpendicularity, the construction worker brings the right-angle corner between the measurement kit 1 and the kit secondary scale 3 close to and fits on the measured corner, and judges the deviation of the perpendicularity through the light transmission principle;

[0059] The measuring tool of the present utility model realizes the telescopic movement relative to the measuring kit by manually operating the sliding of the insert in the nested inner cavity. When used in conjunction with the scale lines, it can achieve the dimension measurement effect as an alternative to a tape measure. The form and position checking component is used in conjunction with a laser level and the scale lines to survey the form and position checking. The measuring tool has the rigid characteristic of not being easily bent, ensuring the accuracy of measurement. There is no need for construction workers to climb high for measurement, which is convenient for construction workers to use and carry.
