Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for conveniently controlling the thickness of water-stabilized paving. Background Art

[0002] During the pavement construction process, cement-stabilized gravel (abbreviated as cement-stabilized gravel) is an important component of the pavement structure layer. During the cement-stabilized gravel paving process, the paving thickness should be controlled section by section to ensure that the thickness of the cement-stabilized gravel reaches the design requirements after rolling. At the same time, the flatness of the cement-stabilized gravel should be controlled to ensure that the flatness of the subsequent asphalt paving meets the design requirements.

[0003] At present, the thickness control of water-stabilized concrete paving in construction mostly adopts the method of fixing steel bars with piles and then tying the steel bars with iron wire to fix the steel wire rope. This construction process cannot intuitively judge the tying height of the steel wire rope, and thus cannot quickly and accurately control the thickness of the water-stabilized concrete paving. At the same time, there is a risk of the steel wire rope slipping when tying the steel wire to fix it, making it difficult to accurately control the thickness of the water-stabilized concrete paving, thereby affecting the flatness of the water-stabilized concrete paving after compaction. At the same time, repeated adjustment of the fixed steel wire rope that has slipped greatly affects the efficiency of the water-stabilized concrete paving. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components.

[0028] Example 1

[0029] Reference Attachment Figure 1-2This embodiment provides a device for controlling the thickness of water-stable paving, which includes an anchor foot 1, a marking plate 2, a height ruler 3, a rope threading platform 4, a spirit level 5, and a locking member 6. The marking plate 2 is provided at the top of the anchor foot 1, the spirit level 5 is located on the marking plate 2, and the height ruler 3 is provided at the top of the marking plate 2 and is perpendicular to the marking plate 2. When the anchor foot 1 is anchored in the building foundation, if the spirit level 5 on the marking plate 2 shows a horizontal level, the height ruler 3 is in a vertical state and can accurately indicate the elevation. The height ruler 3 is provided with an elevation scale that can visually indicate the elevation. The rope threading platform 4 is slidably mounted on the height ruler 3, and the two are connected and fastened by a locking member 6. When the locking member 6 is loosened, the rope threading platform 4 can slide along the height ruler 3. When the locking member 6 is tightened, the rope threading platform 4 can be fixed to a certain position on the height ruler 3. A horizontal rope threading hole 41 is provided on the rope threading platform 4, and the rope threading hole 41 is used to thread the control steel rope. Compared with the method of using iron wire to tie the control steel rope in the prior art, the beneficial effect of this application is that the rope threading platform 4 is used to provide bottom support for the control steel rope, and the locking part 6 is used to fix the height of the rope threading platform 4. During the laying process of the water-stabilized concrete, the influence of external disturbance or loose iron wire on the height of the control steel rope can be reduced, thereby preventing it from sliding down and causing inaccurate elevation, affecting the construction quality.

[0030] Among them, the rope hole 41 and the locking piece 6 are located on both sides of the elevation ruler 3 to facilitate the loosening and tightening operations of the locking piece 6; the axial length of the rope hole 41 is 2 to 5 cm to provide stable support for the control steel rope.

[0031] In order to improve the anchoring efficiency and anchoring stability of the device, the anchor foot 1 is configured such that the diameter of the anchor foot 1 gradually decreases in the direction away from the standard plate 2 .

[0032] In order to improve the connection stability and sliding smoothness between the rope threading platform 4 and the elevation ruler 3 during the sliding process, the elevation ruler 3 in this embodiment is constructed to include: a ruler body 31 and a slide bar 32. The slide bar 32 is located on the outer wall of the ruler body 31 and extends in the same direction as the ruler body 31. The rope threading platform 4 is provided with a slide groove 42 adapted to the slide bar 32. Through the cooperation between the slide bar 32 and the slide groove 42, the contact area is increased, and the stability and smoothness are improved.

[0033] Furthermore, in order to maintain the balance between the elevation ruler 3 and the rope threading platform 4, a plurality of slide bars 32 may be distributed along the circumference of the ruler body 31, and the cross section where the slide bar 32 connects to the ruler body 31 is I-shaped.

[0034] In this embodiment, the locking member 6 is configured as a high-strength bolt, and a threaded hole adapted thereto is provided on the rope threading platform 4. After one end of the locking member 6 passes through the threaded hole, it abuts against the elevation ruler 3. By loosening or tightening the high-strength bolt, the connection tightness between the rope threading platform 4 and the elevation ruler 3 can be controlled, thereby achieving adjustment or fixation of the height of the rope threading platform 4.

[0035] Example 2

[0036] Compared with Example 1, the difference of this embodiment is (refer to the attached Figure 3 ), the locking member 6 includes a slide rod 61, a limit plate 62, a pulling member 63 and a return spring 64. The slide rod 61 slides through the rope threading platform 4, and its two ends are respectively connected to the limit plate 62 and the pulling member 63; the return spring 64 is located between the limit plate 62 and the rope threading platform 4, and extends in the same direction as the slide rod 61; when the limit plate 62 and the pulling member 63 respectively abut the elevation ruler 3 and the rope threading platform 4, the return spring 64 is in a compressed state.

[0037] When the human hand does not apply force to the pulling member 63, the return spring 64 presses the limit plate 62 against the side wall of the height ruler 3, thereby fixing the height of the rope threading platform 4; when the human hand applies force to the pulling member 63 and pulls the slide bar 61 away from the height ruler 3, the rope threading platform 4 can be separated from the height ruler 3, and the height of the rope threading platform 4 can be adjusted by sliding.

[0038] In order to improve the connection stability and assembly convenience, in this embodiment, the pulling piece 63 can be threadedly connected to the slide rod 61, and several slide rods 61 can be connected to the pulling piece 63. A reset spring 64 is installed on each slide rod 61. Through the elastic force of multiple reset springs 64, the clamping force between the limit plate 62 and the elevation ruler 3 and the clamping force between the pulling piece 63 and the rope threading platform 4 are increased.

[0039] In addition to the above-mentioned return spring 64 sleeved on the slide rod 61, more return springs 64 can be added outside the slide rod 61 to further increase the pressing force and improve the connection stability between the rope threading platform 4 and the elevation ruler 3.

[0040] Compared with the prior art, the beneficial effects of the present application are: by using a rope threading platform 4 that can provide stable support for the control steel rope, and a locking member 6 that can provide stability for the rope threading platform 4, the height stability of the control steel rope is improved to prevent it from sliding down and causing inaccurate elevation; the height of the rope threading platform 4 can be intuitively and accurately controlled by the elevation ruler 3, the marking plate 2 and the level 5, thereby improving the accuracy of the elevation.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
