Description

Technical Field

[0001] This application belongs to the field of building formwork construction technology, and more specifically, relates to a formwork measuring device for building construction. Background Technology

[0002] Formwork is a temporary structure used in building construction to support the pouring and shaping of concrete. Its function is to maintain the required shape and size of the concrete before it hardens, ensuring that the dimensions, shape, and position of the concrete structure meet design requirements. The installation accuracy and verticality of the formwork are key factors in ensuring the quality of building construction. After the formwork is installed, its position and verticality need to be measured to guarantee construction quality.

[0003] In existing technologies, there are two methods for measuring templates: visual inspection and tool measurement. Visual inspection, which involves checking the template's flatness with the naked eye, yields results with significant deviations and has been gradually phased out. Tool measurement, using a measuring ruler against the template surface, allows for more precise measurement of installation deviations and verticality, resulting in more accurate and widely applicable results. Existing measuring rulers mainly consist of a vertical pole, a horizontal pole, a ruler, and a plumb line. The resulting rectangular frame shape occupies a large space, making it inconvenient to carry or move. Utility Model Content

[0052] Please refer to the following: Figures 1 to 9 The following describes a formwork measuring device for building construction provided in an embodiment of this application.

[0053] Please see Figures 1 to 3 This application provides a formwork measuring device for building construction, including a vertical pole 10, a horizontal bar 20, a first slider 30, a scale 40, and connecting bolts 50. One end of the horizontal bar 20 is used for positioning with the template and is set horizontally; the other end of the vertical bar 10 is rotatably connected to the horizontal bar 20 and has a first groove 11 in the vertical direction; the first slider 30 is located on one side of the vertical bar 10 and slides with the first groove 11. The first slider 30 has a first mounting hole on the side of the vertical bar 10 that is in contact with it. The first mounting hole can be a threaded hole; one end of the scale 40 is located on the side of the vertical bar 10 away from the first slider 30 and has a second mounting hole that is coaxial with the first mounting hole. The other end of the scale 40 is the measuring end. The connecting bolt 50 passes through the second mounting hole and the first groove 11 and is threaded with the first mounting hole to rotatably connect the scale 40 and the first slider 30; the scale 40 can be switched to a position parallel to or horizontal to the vertical bar 10; the plumb bob 60 hangs down from top to bottom on the horizontal bar 20.

[0054] Compared with the prior art, the beneficial effects of the formwork measuring device for building construction provided in this application are:

[0055] This application provides a formwork measuring device for building construction, comprising a vertical pole 10, a horizontal bar 20, a first slider 30, a scale 40, a connecting bolt 50, and a plumb bob 60. The vertical pole 10 has a first groove 11 along its vertical direction, allowing the first slider 30 to move along the groove 11, thereby changing the height of the scale 40. One end of the horizontal bar 20 is rotatably connected to the top of the vertical pole 10, and the scale 40 is rotatably connected to the first slider 30 via the connecting bolt 50. When measurement is required, the horizontal bar 20 is rotated to be perpendicular to the vertical pole 10, and the scale 40 is rotated to a horizontal measuring position. Then, the connecting bolt 50 is tightened to fix the scale 40 and the first slider 30 together. The end of the horizontal bar 20 is then placed against the surface of the formwork to be measured, causing the plumb bob 60 to drop from the horizontal bar 20. The scale 40 is moved up and down to record the readings at different heights corresponding to the plumb bob 60. By analyzing the measurement results, it can be determined whether the verticality of the formwork installation meets the requirements.

[0056] In this embodiment, both the crossbar 20 and the scale 40 are rotatably mounted. When not in use, the crossbar 20 and the scale 40 can be rotated to a vertical position parallel to the upright 10, so that the device as a whole is in the shape of a long rod, which can be put into a long box or other container for easy storage and carrying.

[0057] The formwork measuring device for building construction provided in this application embodiment is used to measure the installation position and verticality of formwork for building structures such as walls, columns, or beams. For specific usage instructions, please refer to... Figure 2 Before erecting the formwork, the construction worker first marks the edge lines and control lines of walls, columns, beams, etc., on the ground using tools such as a chalk line. The control lines are lines located a certain distance outside the edge lines. After the formwork is erected, the edge lines will be pressed down by the formwork. Without control lines, it is impossible to accurately determine the installation position of the formwork.

[0058] Therefore, construction workers will mark control lines parallel to the edge line at positions such as 10cm, 20cm, or 30cm outside the edge line. After the formwork is erected, on the one hand, measuring devices can be used to measure the difference in distance between the formwork at different heights and the plumb line to determine the verticality of the formwork. On the other hand, by measuring the distance between the formwork and the control line, and adding the thickness of the formwork (the thickness of the formwork is fixed and can be measured in advance), it can be determined whether the formwork is erected on the edge line or exceeds the edge line, and whether the accuracy of the formwork installation position meets the requirements.

[0059] Both the upright 10 and the horizontal bar 20 are long rods. The cross-sections of the upright 10 and the horizontal bar 20 can be square, circular, or oblong, etc. The materials of the upright 10 and the horizontal bar 20 can be metals such as steel and aluminum alloy, or polymer materials such as engineering plastics, as long as they have sufficient structural strength. The upright 10 has a first sliding groove 11, which allows the first slider 30 to move up and down, thereby changing the height of the scale 40 to measure the distance between the template and the plumb bob 60 at different heights, and then calculating the vertical deviation of the template installation.

[0060] When taking measurements, two or three people can work together, with one or two people responsible for taking the measurements and the other person responsible for recording the results.

[0061] One end of the horizontal bar 20 is hinged to the vertical bar 10, and the other end is used for fitting and positioning with the template. The horizontal bar 20 and the vertical bar 10 can be rotatably connected by a pin, allowing them to rotate relative to each other. When the horizontal bar 20 is in a horizontal position, it is perpendicular to the vertical bar 10, and can be used to measure the template. When the horizontal bar 20 is in a vertical position, it is parallel to the vertical bar 10, and can be folded for easy storage and transfer.

[0062] The first groove 11 and the second groove 25 (hereinafter referred to as the second groove) are used for sliding engagement with the corresponding parts. There are no restrictions on the specific shape and size of the groove. Specifically, they can be common groove forms such as square, T-shaped, and dovetail-shaped.

[0063] The ruler 40 has graduations, typically one graduation per millimeter. Different graduations can be set as needed to meet usage requirements. The side of the ruler 40 that is used to adhere to the template has the zero graduation as its starting point. The ruler 40 can be a single measuring ruler or a telescopic measuring ruler. Both single and telescopic rulers 40 are available on the market, and their specific specifications and models are not restricted.

[0064] The first slider 30 is slidably engaged with the first groove 11. When the connecting bolt 50 is loosened, the scale 40 can rotate relative to the first slider 30, at which point the connecting bolt 50 acts as a rotation axis. When the connecting bolt 50 is tightened, the first slider 30 and the scale 40 are fixed together, and the scale 40 can move up and down along the upright 10 with the first slider 30 to measure the distance between the template at different heights and the plumb bob 60, thereby determining whether the verticality of the template installation meets the requirements.

[0065] When the distance between the template and the plumb bob measured at different heights varies greatly, it indicates that the template is not in a vertical plane and the verticality deviation is large.

[0066] Please see Figure 1 and Figure 6In some possible embodiments, a receiving groove 21 is provided at the end where the crossbar 20 is connected to the upright 10, and the upper end of the upright 10 is received in the receiving groove 21, making the overall structure more compact.

[0067] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 In some possible embodiments, the lower surface of the crossbar 20 is provided with a positioning bracket 22. The positioning bracket 22 is L-shaped. One right-angled side of the positioning bracket 22 is connected to the crossbar 20, and the other right-angled side of the positioning bracket 22 is used to abut against the side wall of the upright 10. The positioning bracket 22 is used for the rotational positioning of the crossbar 20.

[0068] The positioning bracket 22 should be made of a material with high rigidity, such as manganese steel, so that it is not easily deformed under stress. The positioning bracket 22 can be fixed by welding or by screws.

[0069] Furthermore, a fifth mounting hole can be provided on the positioning bracket 22, and a sixth mounting hole corresponding to the fifth mounting hole can be provided on the upright 10. Bolts pass through the fifth mounting hole and are threaded into the sixth mounting hole. When the crossbar 20 is perpendicular to the upright 10, to prevent the crossbar 20 from wobbling during measurement, the positioning bracket 22 and the upright 10 can be connected and fixed with bolts to ensure structural stability during use. After measurement, the bolts can be removed, allowing the scale 40, crossbar 20, and upright 10 to be folded into a long rod shape for easy storage.

[0070] Please see Figures 1 to 3 In some possible embodiments, a support plate 23 is provided at the end of the crossbar 20 away from the upright 10. The crossbar 20 is located at the center of the support plate 23 and is perpendicular to the support plate 23. The support plate 23 is in the shape of a square plate, a round plate, a hexagonal plate, etc., and is used to fit with the template to make the support stable during measurement.

[0071] The support plate 23 and the crossbar 20 can be fixedly connected by welding, bonding, or other methods, or they can be detachably connected by screws. The support plate 23 has a through-hole along its thickness, and a fixing bolt 24 passes through this hole. When the template has pre-drilled threaded holes, the support plate 23 and the template can be connected as a single unit using the fixing bolt 24, preventing wobbling during measurement. Furthermore, magnets or other mechanical clamps can be installed on the support plate 23 to improve the stability of the connection with the template.

[0072] Please see Figure 1 , Figure 3 and Figure 9To ensure a perfect fit between the support plate 23 and the template and to eliminate or reduce measurement errors, in some possible embodiments, the support plate 23 is provided with a plurality of fit detection components 70 around the crossbar 20. Each fit detection component 70 includes a sensing element 71 and an indicating element 72. The sensing element 71 is located on the side of the support plate 23 that is used to fit the template; the indicating element 72 is located on the side of the support plate 23 away from the template and is connected to the sensing element 71. When the sensing element 71 fits against the template, the indicating element 72 can generate at least one of a light signal or a sound signal.

[0073] In this embodiment, the bonding detection component 70 is used to detect whether the support plate 23 is fully bonded to the template. Multiple bonding detection components 70 are arranged around the support plate 23. Only when multiple bonding detection components 70 simultaneously generate indication signals does it indicate that the support plate 23 is fully bonded to the template. The bonding detection component 70 includes a sensing element 71 and an indicating element 72. The sensing element 71 can be a pressure sensor, pressure switch, limit switch, etc. When the sensing element 71 contacts the template and a certain pressure is applied, the sensing element 71 generates a sensing signal and transmits it to the indicating element 72. The indicating element 72 can be a light bulb, speaker, etc., powered by a battery. The indicating element 72 emits sound and / or light signals to indicate that the position is bonded to the template. It should be noted that all the above components can be directly purchased from the market, and those skilled in the art can understand and implement them.

[0074] Please see Figure 9 In some possible embodiments, the fit detection assembly 70 further includes a housing 73, an elastic element 74, and a control element. The housing 73 is disposed on the support plate 23 and has a receiving cavity. One end of the sensing element 71 slides within the receiving cavity, and the other end extends out of the receiving cavity to abut against the template. The elastic element 74 is disposed within the receiving cavity, with one end abutting against the sensing element 71 and the other end abutting against the inner wall of the receiving cavity. The elastic element 74 is configured with a pre-tightening force to extend the sensing element 71 out of the receiving cavity. The control element includes a power supply and a resilient contact switch 75. The power supply, the resilient contact switch 75, and the indicator element 72 can be integrated on a circuit board to form a switching circuit. The end of the sensing element 71 housed in the receiving cavity corresponds to the resilient contact switch 75 in the sliding direction of the sensing element 71. When the sensing element 71 abuts against the resilient contact switch 75, the circuit is open, and the indicator element 72 emits an audible or visual indicator signal. When the sensing element 71 separates from the resilient contact switch 75, the circuit is closed, and the indicator element 72 is de-energized.

[0075] In this embodiment, the sensing element 71 is a rod that can slide along the receiving cavity. One end of the sensing element 71 extends out of the outer shell 73 to contact the template, and the other end extends to the position of the elastic contact switch 75. In the free state, the elastic element 74, like a spring, exerts a preload force on the sensing element 71, and the sensing element 71 does not contact the elastic contact switch 75, so the indicating element 72 does not generate a signal. When the support plate 23 is attached to the template surface, the sensing element 71 moves inward against the preload force, pushing the elastic contact switch 75 to close, thus completing the circuit and energizing the indicating element 72 to generate a signal.

[0076] The power source can be a dry cell battery, button cell battery, lithium battery, etc. The elastic contact switch 75 has a spring plate. When the spring plate is compressed, it can close the switch and conduct the circuit. When the pressure is released, the spring plate returns to its original position, and the switch opens.

[0077] Of course, the above-mentioned flexible contact switch 75 is only one implementation of this application. In actual use, other types of switches can also be selected as long as they can control the on / off state of the circuit.

[0078] Please see Figure 8 and Figure 9 In some possible embodiments, the support plate 23 has multiple fourth mounting holes around the crossbar 20. The fourth mounting holes penetrate the thickness direction of the support plate 23. The outer shell 73 is correspondingly provided in the fourth mounting holes. The outer shell 73 is threadedly engaged with the fourth mounting holes, which is convenient for installation. It also allows for fine adjustment of the distance of the outer shell 73 protruding from the support plate 23, ensuring that the height of the multiple outer shells 73 protruding is consistent.

[0079] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 In some possible embodiments, the crossbar 20 has a second groove 25 along its length. A formwork measuring device for construction also includes a second slider 26, a fastener 27, a winding spool 12, and a winding wheel 28. The second slider 26 is slidably disposed in the second groove 25; the fastener 27 is disposed between the second slider 26 and the crossbar 20 for locking the second slider 26 and the crossbar 20; the winding spool 12 is disposed at the top of the upright 10 for winding the rope 61; and the winding wheel 28 is disposed on the second slider 26.

[0080] In this embodiment, the spool 12 is used to wind the rope 61. The spool 12 can be a single spool or a spool with an automatic winding function. One end of the rope 61 is wound around the spool 12, and the other end of the rope 61 passes around the spool 12 and connects to the plumb bob 60. The second slider 26 can move along the second groove 25, so that the position of the plumb bob 60 is as follows: Figure 2The control lines shown correspond vertically to the ground markings, which facilitates the measurement of the distance between the template and the control lines to determine the accuracy of the template's installation position.

[0081] The fastener 27 is detachably connected between the second slider 26 and the crossbar 20, and can be a bolt, cable tie, rope, etc. When the position of the second slider 26 is fixed, the second slider 26 can be fixed to the crossbar 20 by the fastener 27.

[0082] Please see Figure 3 and Figure 5 In some possible embodiments, the scale 40 has a vertically extending clearance notch 41 at the end away from the pole 10, through which the plumb bob 60 passes. The scale 40 has graduations on both sides, making it easy to check the corresponding graduation value of the plumb bob 60.

[0083] Please see Figure 7 In some possible embodiments, a formwork measuring device for building construction also includes an extension rod 80, which is detachably connected to the bottom of the upright 10, and the extension rod 80 is provided with a third groove along its own length.

[0084] like Figure 7 As shown, the function of the extension rod 80 is to extend the upright rod 10. At least one of the upright rod 10 and the extension rod 80 is equipped with a scale 40 to meet the measurement requirements.

[0085] A scale 40 can be provided on the first slide groove 11 and the third slide groove respectively. Alternatively, the scale 40 can be provided on either the upright 10 or the extension rod 80. Specifically, the first slider 30, the scale 40, and the first slide groove 11 are detachably connected by connecting bolts 50. The connecting bolts 50 are adapted to pass through the first mounting hole, the third slide groove, and the second mounting hole to rotatably connect the scale 40 and the first slider 30 to the extension rod 80. The scale 40 can be switched to a position parallel or horizontal to the upright 10.
