Description

Technical Field

[0001] The utility model relates to the technical field of building plate detection, in particular to a building engineering plate density detection device. Background Art

[0002] Construction engineering board is a material used in building structures, often used to make casting formwork for building walls, roofs, floors, and partitions. It is mainly made of a mixture of wood particles, fine sawdust or other fiber materials and an appropriate amount of adhesive. When selecting construction engineering boards, in order to ensure that the structural strength of the construction engineering boards meets the design requirements, the density of the construction engineering boards needs to be tested, and the corresponding testing equipment needs to be used.

[0003] Chinese utility model patent CN219715147U discloses a construction board density detection device, including a mounting frame, a driving assembly, a winding wheel, a steel cable and a clamping assembly, etc. The right side of the upper part of the mounting frame is connected to the driving assembly by bolts, the driving assembly is wound with a steel cable, the lower side of the upper right part of the mounting frame is rotatably connected to the winding wheel, and the bottom end of the steel cable is connected to the clamping assembly. The utility model enables the construction board to maintain a vertical state through the clamping assembly, reduces the resistance of the construction board to enter water, and generates a hot air flow through the hot air blower to allow the nozzle to air dry the construction board after being immersed in water, so that the water droplets attached to the construction board can be accelerated to return to the water tank, so that the inspection personnel can read the scale bar more accurately.

[0004] When the immersed board is lifted out of the water, the moisture penetrates into the inside of the board and accumulates. The hot air blower can only dry the surface of the building engineering board, and most of the moisture evaporates during drying and does not drip back into the water tank. The moisture immersed in the board and the dried moisture cause a large error in the volume measurement of the building engineering board, which has a great impact on the density detection of the board.

[0005] Therefore, we propose a device for detecting density of construction engineering boards. Utility Model Content

It is unnecessary to take out the construction engineering boards, and the adverse interference of water droplets attached to the construction engineering boards after they are taken out of water on the volume measurement can be effectively avoided. The accuracy of density detection of construction engineering boards can be improved, and the use is relatively simple, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0017] The construction engineering board density detection device can control the construction engineering board to move up and down through the arranged winch and construction engineering board fixing assembly when measuring the volume of the construction engineering board, so as to ensure that the construction engineering board is completely immersed in water. At this time, the volume of water flowing from the inner overflow frame to the outer water storage frame through the overflow hole is the volume of the construction engineering board. After the water surface is stable, the water depth can be measured to obtain the volume of the construction engineering board (the product of the water depth and the inner bottom surface of the outer water storage frame and the outer area of ​​the inner overflow frame minus the volume of the construction engineering board clamping strip is the volume of the construction engineering board). The density of the construction engineering board can be calculated in combination with the pre-measured weight of the construction engineering board without taking out the construction engineering board, thereby effectively avoiding the adverse interference of water drops attached to the construction engineering board after it is taken out of the water on the volume measurement of the construction engineering board, thereby improving the accuracy of the construction engineering board density detection;

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-4As shown, a construction engineering board density detection device comprises an outer water storage frame 1, an inner overflow frame 2 is fittedly installed on the inner bottom surface of the outer water storage frame 1, a plurality of overflow holes 3 distributed at equal intervals are constructed around the inner overflow frame 2, the center height of the overflow hole 3 is flush with the top of the outer water storage frame 1, a bracket 4 extending to the top of the inner overflow frame 2 is fittedly installed on the top of the outer water storage frame 1, a winch 5 is installed on the surface end of the bracket 4, and a cable passing through the end of the bracket 4 is wound on the winch 5, and a construction board fixing component 6 is connected to the bottom of the cable, and a scale line 9 is constructed on the outer periphery of the outer water storage frame 1.

[0026] During the pre-measurement, it is necessary to inject pure water flush with the bottom of the overflow hole 3 into the inner overflow frame 2. The winch 5 is a common lifting equipment, which is used to control the up and down movement of the construction engineering board fixed inside the engineering board fixing assembly 6 to completely immerse the construction engineering board in water. The engineering board fixing assembly 6 is used to clamp the construction engineering board and have a counterweight effect to prevent the construction engineering board from floating on the water when the density is low.

[0027] Furthermore, the engineering board fixing assembly 6 includes an adjusting plate 61, the bottom of the adjusting plate 61 is constructed with a straight groove, and a symmetrically arranged limit slider 64 is slidably arranged in the straight groove, the limit sliders 64 are all threadedly connected to the outer periphery of the rocker 63, the rocker 63 is rotatably installed in the straight groove, and the end of the rocker 63 extends to the outside of the adjusting plate 61, the bottom of the limit slider 64 is fitted with a vertical bar 65, and a symmetrically arranged engineering board clamping bar 66 is installed at the bottom of the vertical bar 65, and a transverse groove is constructed on the adjacent side of the engineering board clamping bar 66.

[0028] The external threads on the outer periphery of the rocker 63 rotate in opposite directions. Since the widths of the sampled construction boards are different, when the rocker 63 is rotated, the limit slider 64 moves in the opposite direction, so that the spacing of the board clamping strips 66 can be adjusted, making it convenient to clamp the construction board between the transverse grooves to adapt to the width changes of the construction board and quickly clamp and fix the construction board.

[0029] Furthermore, a water pump 7 is installed on the outer wall of the inner overflow frame 2, and the water suction port of the water pump 7 is connected to a water suction pipe 8 extending to the inner bottom surface of the outer water storage frame 1. The side wall of the inner overflow frame 2 is constructed with a circular hole adapted to the water outlet of the water pump 7.

[0030] After completing a single density test operation, the water in the outer water storage frame 1 is pumped back into the inner overflow frame 2 through the water pump 7 and the water pump pipe 8, which can reduce the waste of water resources and be more energy-saving and environmentally friendly.

[0031] Furthermore, reinforcement strips 10 are fixed between both sides of the bracket 4 and the surface of the outer water storage frame 1 , and reinforcement plates 11 are fixed between the inner walls of the bracket 4 .

[0032] Under the action of the reinforcement strip 10 and the reinforcement plate 11 , the stability between the bracket 4 and the outer water storage frame 1 can be effectively improved.

[0033] Furthermore, a fixing seat 62 is installed at the top center of the adjustment plate 61 , and a pin that passes through the cable is inserted between the outer periphery of the fixing seat 62 .

[0034] After the latch is passed through the knot at the end of the cable, the adjusting plate 61 can be installed and connected with the cable of the winch 5, so that the engineering plate fixing component 6 of the corresponding model and size can be easily removed and replaced.

[0035] It should be noted that the utility model is a density detection device for construction engineering boards. Before measurement, the weight of the construction engineering board is measured, and the rocker 63 is rotated in advance according to the width of the construction engineering board. Under the action of the rocker 63, the limit slider 64 slides in the straight groove until the spacing of the side away from the transverse groove of the engineering board clamping strip 66 is equal to the width of the construction engineering board. Then, the construction engineering board is horizontally inserted into the transverse groove, and the center of the construction engineering board is kept directly below the bottom of the cable. At this time, the construction engineering board and the engineering board fixing assembly 6 are in a horizontal state, and then the winch 5 is controlled to release the cable to immerse the construction engineering board in water until the upper surface of the engineering board clamping strip 66 is aligned with the water surface. The water in the inner overflow frame 2 flows into the outer water storage frame 1 through the overflow hole 3. When the water surface is stable, take a liquid level gauge to measure the water depth in the outer water storage frame 1. The product of the water depth and the area between the inner bottom surface of the outer water storage frame 1 and the outer side of the inner overflow frame 2 minus the volume of the engineering board clamping strip 66 is the volume of the construction engineering board. After the measurement, the winch 5 is controlled to lift the construction engineering board and take the construction engineering board out from between the engineering board clamping strips 66. The water in the outer water storage frame 1 is pumped back to the inner overflow frame 2 by the water pump 7, and the water lost in the measurement is replenished into the inner overflow frame 2. After the remaining water in the outer water storage frame 1 is completely removed, the density measurement operation can be carried out again.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
