Description

Technical Field

[0001] The utility model relates to the technical field of cushion block adjustment, in particular to a cushion block capable of controlling the thickness of a mortar belt. Background Art

[0002] During the construction process, since the mortar belt is thicker than the mortar joints of ordinary masonry, its thickness cannot be guaranteed by ordinary masonry construction methods. If the mortar belt is constructed first and the upper masonry is constructed after the strength of the mortar belt is improved, it will affect the adhesion between the mortar belt and the upper masonry and extend the masonry construction period. If the water-cement ratio of the masonry mortar is reduced, that is, it is adjusted into a dry hard mortar, it will affect the bond strength between the steel bars and the mortar in the mortar belt, so it is necessary to use pads to support the upper masonry when the mortar belt is not poured.

[0003] The existing mortar belt pads have a relatively simple structure, and most of them are integrated designs. In actual use, their height cannot be adjusted, resulting in a certain gap between the lower masonry and the upper masonry. This may cause safety hazards during construction due to the existing gap. Therefore, a pad that can control the thickness of the mortar belt is proposed to solve the above problem. Utility Model Content

When the work is completed, one end of the limit rod 9 is threadedly installed in one of the threaded holes 7, and then the limit rod 9 is continuously rotated, and the other end of the limit rod 9 is threadedly installed in the threaded groove 8 aligned with one of the threaded holes 7, so that the fixed connection between the turntable 5 and the base 1 is completed, so as to prevent the cushion box 13 from rotating on its own after being squeezed by the steel bar, causing the moving block 4 to move and synchronously drive the cushion box 13 downward after being displaced. When the distance between the cushion box 13 is low, the moving block 4 can be driven to move toward the turntable 5 by rotating the turntable 5 counterclockwise, and the moving block 4 squeezes the supporting block 12 when it moves, so that the supporting block 12 is When the supporting block 12 moves upward, the cushion box 13 fixedly installed on the top side of the supporting block 12 can also move upward synchronously, so that it can play a role in supporting the upper masonry when there is no pouring, and if the height of the cushion box 13 is too high, it is only necessary to rotate the turntable 5 clockwise to drive the moving block 4 away from the turntable 5, so that the cushion box 13 will move downward, and it can be adjusted according to the distance between the cushion box 13 and the upper masonry, and because the top side of the moving block 4 and the bottom side of the supporting block 12 are both inclined, so when the moving block 4 moves back and forth, the two inclined surfaces are in contact, so that the supporting block 12 moves up or down.

[0022] Specifically, the guide assembly includes two guide rods 11 fixedly installed on the top side of the top plate 10, and two guide grooves 2 are provided on the top side of the base 1. The two guide rods 11 are adapted to the two guide grooves 2, and the two guide rods 11 are inserted into the two guide grooves 2. Moreover, through the set guide rods 11 and guide grooves 2, when the support block 12 drives the top plate 10 to move, the two guide rods 11 will always be located in the guide grooves 2 and can play a guiding role during movement.

[0023] Specifically, the clamping assembly includes a round hole on one side of the cushion box 13, a bidirectional screw 14 is rotatably arranged in the round hole, the other end of the bidirectional screw 14 is rotatably connected to the inner wall of one side of the cushion box 13, the other end of the bidirectional screw 14 is fixedly installed with a hand wheel 22, and two guide rods 17 are fixedly installed on the inner wall of the cushion box 13, the two guide rods 17 are located on both sides of the bidirectional screw 14, and two groups of positive grooves 15 and two groups of reverse grooves 16 are respectively opened on the outer side of the bidirectional screw 14, and the bidirectional screw 14 and the two guide rods 17 are fixedly installed with the inner wall of the cushion box 13. Two first sliders 18 and two second sliders 19 are slidably installed respectively, and the two first sliders 18 and the two second sliders 19 slide on the two positive grooves 15 and the two reverse grooves 16 respectively. The top sides of the two first sliders 18 and the two second sliders 19 are fixedly installed with first clamping plates 20 and second clamping plates 21 respectively. The first clamping plates 20 and the second clamping plates 21 are symmetrically arranged, and the first clamping plates 20 and the second clamping plates 21 are both provided with arc openings on the sides close to each other. There are two through circular holes, which are respectively located between the two groups of first sliders 18 and second sliders 19. When it is necessary to place the longitudinal steel bars, the longitudinal steel bars are sequentially passed through the two through circular holes opened in the cushion box 13, and then the bidirectional screw 14 is rotated by turning the hand wheel 22 clockwise. When the bidirectional screw 14 rotates, the two groups of first sliders 18 and second sliders 19 are driven to approach each other, and then the two groups of first clamping plates 20 and second clamping plates 21 are driven to approach each other, so that the two longitudinal steel bars can be clamped. If thicker longitudinal steel bars need to be placed, the two groups of first sliders 18 and second sliders 19 can be moved away from each other by turning the hand wheel 22 counterclockwise. After the thicker longitudinal steel bars are placed, the hand wheel 22 can be turned clockwise again to drive the two groups of first sliders 18 and second sliders 19 to approach each other, so that the thicker steel bars can also be clamped. The distance between the two groups of first sliders 18 and second sliders 19 can be adjusted, so that steel bars of any thickness can be clamped.

[0024] When in use: when using pads on different concrete protective layers, the pad box 13 and the base 1 are moved under the upper masonry, and then adjusted according to the distance of the specified height between the pad box 13 and the upper masonry. When the distance is low, the turntable 5 can be rotated counterclockwise to drive the moving block 4 to move toward the turntable 5. When the moving block 4 moves, it squeezes the supporting block 12, so that the supporting block 12 moves upward. When the supporting block 12 moves upward, the pad box 13 fixedly installed on the top side of the supporting block 12 can also move upward synchronously, so as to play a role in supporting the steel bars. If the height of the pad box 13 is too high, it only needs to rotate the turntable 5 clockwise to drive the moving block 4 away from the turntable 5, so that the pad box 13 will move downward. It can be adjusted to a suitable position according to the distance between the pad box 13 and the steel bars. When longitudinal steel bars need to be placed, The longitudinal steel bars are passed through the two through circular holes opened in the cushion box 13 in sequence, and then the bidirectional screw 14 is rotated by turning the hand wheel 22 clockwise. When the bidirectional screw 14 rotates, the two groups of first sliders 18 and second sliders 19 are driven to approach each other, and then the two groups of first clamping plates 20 and second clamping plates 21 are driven to approach each other, so that the two longitudinal steel bars can be clamped. If thicker longitudinal steel bars need to be placed, the two groups of first sliders 18 and second sliders 19 can be moved away from each other by turning the hand wheel 22 counterclockwise. After the thicker longitudinal steel bars are placed, the hand wheel 22 can be turned clockwise again to drive the two groups of first sliders 18 and second sliders 19 to approach each other, so that the thicker steel bars can also be clamped. The distance between the two groups of first sliders 18 and second sliders 19 can be adjusted, so that steel bars of any thickness can be clamped.
