Description

Technical Field

[0001] The invention relates to the technical field of template detection, and in particular to a beam template deflection detection device and method based on a level. Background Art

[0002] The reason for arching the beam formwork is to increase the stability and load-bearing capacity of the structure. Arching can change the force mode of the beam formwork from pure bending to the combined action of bending and stretching, thereby improving the bearing capacity of the beam formwork. In addition, arching can also reduce the deflection of the beam formwork, making it more solid and stable. Generally, the arch height is 1 / 1000 to 3 / 1000 of the beam span. The specific value should be determined according to design requirements and construction experience.

[0003] Due to natural gravity settlement, the center of the ceiling will drop several centimeters after the formwork is removed. Therefore, in order to avoid the above two consequences, all structures with larger spans must adopt the arching method during construction. The so-called arching is actually an advance measurement, or a preventive measure, that is, increasing the height of the middle part of the span to an appropriate proportion. A smaller arch can be measured with a feeler gauge, and a larger arch can be measured with a steel ruler.

[0004] Since the amount of arching is small, it is not convenient to find the reference starting reading point when measuring with a feeler gauge or a steel ruler, and the results based on experience have large errors.

[0005] Therefore, it is necessary to provide a beam formwork deflection detection device and method based on a level to solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a beam formwork deflection detection device and method based on a level to solve the problem that the existing small arching amount makes it inconvenient to measure with tools and the judgment based on experience has a large error.

[0007] The technical solution to achieve the above purpose is:

[0008] The present invention provides a beam template deflection detection device based on a level, comprising:

[0009] Base plate;

[0010] A first clamping plate and a second clamping plate arranged on the bottom plate and having an adjustable spacing, wherein the first clamping plate and the second clamping plate can be clamped at corresponding positions of the beam formwork by adjusting the spacing;

[0011] A ruler is connected to the bottom of the base plate and extends downward.

[0012] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that a strip groove is provided on the bottom plate;

[0013] The first clamping plate is fixedly mounted on the bottom plate;

[0014] The second clamping plate is slidably arranged in the strip-shaped groove, and a spring is connected between the second clamping plate and the first clamping plate. The spring applies a pulling force to the second clamping plate so that the second clamping plate moves closer to the first clamping plate.

[0015] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that a sliding block is fixedly provided at the bottom of the second clamping plate, the sliding block is adapted to the strip groove, and the sliding block is slidably arranged in the strip groove.

[0016] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that the sliding block is in the shape of an elongated strip.

[0017] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that a mounting strip is provided at the bottom of the bottom plate;

[0018] The ruler is detachably connected to the mounting bar.

[0019] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that an insert strip is provided on the top of the scale;

[0020] The installation bar is provided with a slot matched with the inserting bar, and the inserting bar can be inserted into the slot.

[0021] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that a limiting groove is provided on the inserting strip;

[0022] A limiting strip is provided on the installation strip corresponding to the limiting groove, and the limiting strip can be inserted into the limiting groove.

[0023] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that the first clamping plate and the second clamping plate are triangular in shape and hollow in the middle.

[0024] A further improvement of the beam formwork deflection detection device based on a level meter of the present invention is that rubber pads are provided on the clamping surfaces of the first clamping plate and the second clamping plate.

[0025] The present invention also provides a beam template deflection detection method based on a level, comprising the following steps:

[0026] Provide the above-mentioned detection device, and clamp the detection device on the support and mid-span position of the beam template through the first clamping plate and the second clamping plate, so that the bottom plate is closely fitted with the bottom of the beam template;

[0027] A level is set up in the middle between the two detection devices, and the level is adjusted to be in the same plane as the central axes of the two detection devices;

[0028] The level is used to read the scales of the two detection devices, and the arch height of the beam template is obtained according to the difference between the reading values.

[0029] The beneficial effects of the beam formwork deflection detection device and method based on the level meter of the present invention are as follows:

[0030] (1) The present invention achieves the effect of fixing the scale under the beam template by setting the first clamping plate, the second clamping plate and related components. Compared with the existing method of judging the arching degree of the beam template by experience, the level can be used to quantitatively judge and detect whether the arching of the beam template meets the requirements of the specification;

[0031] (2) The present invention increases the length of the slider so that the second clamping plate has a larger stroke on the bottom plate, so the maximum distance between the first clamping plate and the second clamping plate is also larger, and the application range of the device is wider;

[0032] (3) A limit bar is provided on the inserting strip of the present invention, and the limit bar is adapted to the inserting strip. When the inserting strip is inserted into the mounting strip, the limit bar is inserted into the bar-shaped groove on the inserting strip. Since the limit bar constrains the inserting strip, the inserting strip cannot rotate in the mounting strip, and the scale is fixedly mounted on the inserting strip and therefore cannot rotate either.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] See also Figure 1The present invention provides a beam formwork deflection detection device and method based on a level, which is used to solve the problem that the structure judged based on experience has a large error when the existing arching amount is small, and is also used to solve the problem that the tool is difficult to measure when the arching amount is small. The beam formwork deflection detection device and method based on a level of the present invention can quantitatively measure and detect the arching amount of the beam formwork with a large installation span. The beam formwork deflection detection device and method based on a level of the present invention are described below in conjunction with the accompanying drawings.

[0040] See also Figure 1 , showing a schematic diagram of the structure of the beam template deflection detection device based on the level meter of the present invention. Figure 2 , showing a schematic diagram of the structure of the clamping part of the beam template deflection detection device based on the level meter of the present invention from the first perspective. Figure 1 and Figure 2 , the foundation pit combined supporting structure of the present invention is described.

[0041] like Figure 1 and Figure 2 As shown, the beam formwork deflection detection device based on the level of the present invention includes a base plate 104, a first clamping plate 101, a second clamping plate 102 and a scale 200, wherein the first clamping plate 101 and the second clamping plate 102 are arranged on the base plate 104 and the spacing is adjustable, and the first clamping plate 101 and the second clamping plate 102 can be clamped at corresponding positions of the beam formwork by adjusting the spacing; the scale 200 is connected to the bottom of the base plate 104 and extends downward.

[0042] When in use, adjust the spacing between the first clamping plate 101 and the second clamping plate 102 so that the first clamping plate 101 and the second clamping plate 102 can be clamped at corresponding positions of the beam formwork, such as at the support and mid-span position of the beam formwork, and fix the bottom plate 104 at the corresponding position of the beam formwork through the first clamping plate 101 and the second clamping plate 102 so that the bottom plate 104 and the corresponding position of the beam formwork fit tightly. At this time, the scale 200 is vertically set below the beam formwork, and then a level is set on the ground or working surface below the beam formwork, and the reading of the scale 200 is read using the level, and then the height difference of the beam formwork support and the mid-span position can be calculated, and then the arch height or deflection of the beam formwork can be detected based on the arch height of the beam formwork.

[0043] In a specific embodiment of the present invention, Figure 3As shown, a strip groove is provided on the bottom plate 104; the first clamping plate 101 is fixedly mounted on the bottom plate 104; the second clamping plate 102 is slidably arranged in the strip groove, and a spring 106 is connected between the second clamping plate 102 and the first clamping plate 101, and the spring 106 applies a pulling force to the second clamping plate 102 so that the second clamping plate 102 moves toward the direction of the first clamping plate 101. The provision of the spring 106 enables the second clamping plate 102 and the first clamping plate 101 to be clamped on the beam template.

[0044] Further, a hanging pin 108 is provided on the second clamping plate 102, and a hanging pin is also provided on the first clamping plate 101. Both ends of the spring 106 are provided with hooks, which are hung on the corresponding hanging pin 108 through the hooks. Preferably, the hanging pin 108 is made of iron nails.

[0045] By arranging the spring 106 in a hanging manner, the spring 106 can be conveniently disassembled and assembled, so as to facilitate replacement of springs with different elastic coefficients.

[0046] Furthermore, a slider 103 is fixedly provided at the bottom of the second clamping plate 102 . The slider 103 is matched with the strip groove, and the slider 103 is slidably arranged in the strip groove.

[0047] After the slider 103 is set, the end of the spring 106 can be connected to the end of the slider 103, that is, a hanging pin 108 can be set at the end of the slider 103, and the end of the spring 106 can be hung on the hanging pin 108 at the end of the slider 103.

[0048] Furthermore, the slider 103 is in the shape of a long strip. The length of the slider 103 is a certain length, and preferably the length of the slider 103 is greater than or equal to half the length of the strip groove. The length of the slider 103 can allow the second clamping plate to have a larger stroke on the bottom plate, so the maximum distance between the first clamping plate and the second clamping plate is also larger, making the device more applicable.

[0049] A fixing block 107 is arranged at the bottom of the first clamping plate 101 , and the fixing block 107 is fixedly mounted on the bottom plate 104 .

[0050] The upper ends of the sliding block 103 and the fixing block 107 are flush with the upper end of the bottom plate 104 .

[0051] Furthermore, if Figure 4 As shown, a mounting strip 105 is provided at the bottom of the base plate 104 ; the scale 200 is detachably connected to the mounting strip 105 .

[0052] The top of the ruler 200 is provided with an inserting strip 110 ; the mounting strip 105 is provided with a slot adapted to the inserting strip 110 , and the inserting strip 110 can be inserted into the slot. The shape of the inserting strip 110 is adapted to the shape of the slot, and the lower end of the inserting strip 110 is connected to the ruler 200 .

[0053] Preferably, a limiting groove is provided on the inserting strip 110; a limiting strip 111 is provided on the mounting strip 105 corresponding to the limiting groove, and the limiting strip 111 can be inserted into the limiting groove. The limiting strip 111 is adapted to the limiting groove, and when the inserting strip 110 is inserted into the slot, the limiting strip 111 is inserted into the limiting groove. Due to the constraint of the limiting strip on the inserting strip, the inserting strip cannot rotate in the mounting strip, and the scale 200 is fixedly mounted on the inserting strip and therefore cannot rotate.

[0054] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the first clamping plate 101 and the second clamping plate 102 are triangular in shape, and the middle part is hollow.

[0055] During the process of clamping the beam formwork, the first clamping plate 101 and the second clamping plate 102 can be held to separate the two, and then clamped on the beam formwork, which is convenient for the staff to operate.

[0056] In a specific embodiment of the present invention, Figure 2 As shown, rubber pads 109 are provided on the clamping surfaces of the first clamping plate 101 and the second clamping plate 102 .

[0057] The surface of the rubber pad 109 is provided with horizontal stripes, and the rubber pad 109 can increase the friction coefficient between the first clamp plate 101 and the second clamp plate 102 and the beam formwork. When the pressure of the first clamp plate 101 and the second clamp plate 102 on the beam formwork is constant, the larger friction coefficient generates a greater friction force between the beam formwork and the rubber pad 109, preventing the device from falling off the beam formwork.

[0058] like Figure 5 As shown, when in use, first pull the second clamp 102 of the beam formwork deflection detection device based on the level outward, use the tension of the spring 106 to clamp the first clamp 101 and the second clamp 102 on the beam formwork, and install them on the support and mid-span position of the beam formwork, keep the bottom plate 104 tightly fit with the bottom plate 104 of the beam formwork, then set up the level in the middle position between the two devices, keep the level and the central axis of the device roughly in the same plane, finally read the readings on the two front and rear scales 200 from the level, and obtain the arch height of the beam formwork based on the difference between the reading values.

[0059] By setting the first clamping plate 101, the second clamping plate 102 and related components, the effect of fixing the scale 200 under the beam formwork is achieved. Compared with the existing method of judging the arching degree of the beam formwork by experience, the level can be used to quantitatively judge and detect whether the arching of the beam formwork meets the requirements of the specification.

[0060] The detection device of the present invention utilizes the principle of measuring height difference with a level instrument to measure the height difference between a beam template support and the mid-span position to obtain the arch height of the beam, thereby detecting the arch height or deflection of the beam.

[0061] The present invention also provides a beam formwork deflection detection method based on a level, and the detection method is described below.

[0062] The detection method of the present invention comprises the following steps:

[0063] Provide the above-mentioned detection device, and clamp the detection device on the support and mid-span position of the beam template through the first clamping plate and the second clamping plate, so that the bottom plate is closely fitted with the bottom of the beam template;

[0064] Set up a level gauge in the middle between the two detection devices, and adjust the level gauge and the central axes of the two detection devices to be in the same plane;

[0065] The scales of the two detection devices are read using a level, and the arch height of the beam formwork is obtained based on the difference between the reading values.

[0066] The present invention is described in detail above in conjunction with the embodiments of the drawings, and those skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute limitations of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
