Description

Technical Field

[0001] The present invention relates to the technical field of building floor leveling, and specifically to a building construction floor leveling mechanism. Background Technique

[0002] In modern building construction, when pouring construction on the ground (ceiling), it is necessary to first build wooden formwork, and then bind the beam and slab steel bars on the formwork. According to the building construction specifications and requirements, steel bars with specified binding sizes and spacings are placed, and then appropriate amounts of concrete are poured on the formwork and steel bars using pouring and vibrating equipment. At the same time, to ensure the thickness size specifications and ground flatness of the poured ground (ceiling), leveling needs to be carried out synchronously during ground pouring and vibration to ensure that the flatness and thickness size of the building construction ground meet the construction specifications.

[0003] In the existing ground leveling process, generally when in use, first according to the 1-meter line points set by construction layout (the 1-meter line points are generally directly set on external facilities such as external exposed steel bars or scaffolding in building construction, and these external facilities are stably positioned and not easily loosened), while the tile workers are carrying out pouring and vibration, they use a T-shaped scraper for manual ground leveling. After the ground is leveled, a tape measure and a laser device are used to measure the distance between the leveled ground and the 1-meter line points, so as to measure whether the thickness size of the ground during leveling in building construction meets the specification requirements, and ensure that the ground thickness can meet the bearing capacity and sound insulation effect of building construction.

[0004] However, in the actual use process, although the ground leveling operation is convenient, ensuring the thickness size of the leveled ground is directly limited by the experience and on-site performance of the construction workers. Therefore, in actual leveling operations, the actual formed thickness of the ground is likely to vary, affecting the overall bearing strength and sound insulation effects of the ground.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original ground leveling mechanism. Summary of the Invention

At the same time, it is convenient to adjust the ground thickness while leveling the ground. The specific content is as follows:

[0026] 1. The triangular support structure formed by the vehicle frame and the auxiliary support feet facilitates the placement and movement of the ground leveling mechanism. At the same time, during building construction, since the construction site is generally directly located between the tied steel bars, the unevenness and instability of the placement position of the leveling mechanism will be caused by the layout of the steel bars. At the same time, the telescopic installation of the auxiliary support feet, under the installation action of the second motor screw rod assembly, facilitates the positioning and stability of the leveling mechanism at the construction site. Moreover, the lifting action of the hydraulic telescopic part and the sliding block at its end pushes the front positioning frame to adjust the horizontal position under the connection action of the rotating connector. Through the observation of the spirit level bubble, the front positioning frame, the bottom support and the front scraper installed at its bottom can be horizontally adjusted, achieving the effect of rapid horizontal adjustment of the front scraper, making the operation more convenient during subsequent ground leveling, and the leveled ground is not prone to tilting;

[0027] 2. The threaded connection method between the front positioning frame and the bottom support is used for lifting, which is convenient for separately lifting and adjusting the bottom support and the front scraper after the horizontal calibration of the front positioning frame and the bottom support. Thus, according to the requirements of building construction, the distance between the front scraper and the top surface of the formwork under the layout steel bars can be changed. Through this distance adjustment, when the front scraper is leveling the ground, the thickness of the formed building ground can be directly changed, improving the convenience of its operation and the standardization of the formed building ground;

[0028] 3. Both the movable cross bar and the front scraper are assembled and installed. During use, the lengths of the movable cross bar and the front scraper can be adaptively changed according to the length and width of the ground to be leveled. During the ground leveling operation, single - time operation can be carried out, improving the scope of the ground leveling operation;

[0029] Furthermore, when leveling the ground of large - span building construction, during the leveling operation of the front scraper, the sliding friction reaction force received is greater. To improve the efficiency of the ground leveling operation, when leveling the large - span building ground, the first push handle and the second push handle can be selected according to the requirements. The first push handle can be pushed by a single person to level the ground with the front scraper, while the second push handle requires multiple people to push the front scraper to achieve the ground leveling operation.

Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1: Please refer to Figures 1-4 , the present invention provides a technical solution: a building construction ground leveling mechanism, including: a vehicle frame 1, which is installed with movable wheels at the bottom, and a rotating connector 2 is fixed in the middle of the front side of the vehicle frame 1, and the rotating connector 2 is movably connected to the middle of the front positioning frame 3;

[0044] As Figure 3 and Figure 4As shown, the auxiliary support leg 13 is connected to the middle of the back of the vehicle frame 1, and a movable wheel is installed at the bottom of the auxiliary support leg 13, and the auxiliary support leg 13 and the lower end of the vehicle frame 1 are arranged in a triangular distribution; the auxiliary support leg 13 and the vehicle frame 1 form a penetrating relative telescopic structure, and a second motor screw rod assembly 14 and an elastic member are fixed inside the penetration part of the vehicle frame 1 and the auxiliary support leg 13, and the upper end of the second motor screw rod assembly 14 and the auxiliary support leg 13 are in a penetrating threaded connection;

[0045] In the use of the above technical solution, since the ground leveling in building construction is the operation of pouring the beam and slab after formwork support and steel bar binding, and after the concrete is poured and vibrated, the concrete is scraped flat to achieve the leveling operation; so in actual operation, the leveling mechanism will be directly placed on the layout steel mesh in the building construction site, and the construction site is full of layout and bound steel bars;

[0046] Based on the above conditions, the construction site where the leveling mechanism is placed is in an uneven state. The triangular support structure at the bottom of the vehicle frame 1 and the auxiliary support leg 13 is convenient to improve the stability of the placement and positioning of the leveling mechanism. At the same time, through the installation and threaded connection method of the second motor screw rod assembly 14 of the auxiliary support leg 13, the relative telescopic of the auxiliary support leg 13 and the vehicle frame 1 can be controlled, and the placement stability of the leveling mechanism can be further adjusted.

[0047] Embodiment 2: On the basis of Embodiment 1, the present invention also as Figure 1 and as Figure 5 、 Figure 6 As shown, the technical solution further includes: a horizontal adjustment mechanism, which is arranged on the side wall of the vehicle frame 1 and is used for controlling the horizontal inclination of the front positioning frame 3;

[0048] And a spirit level bubble 4 is fixed on the top of the front positioning frame 3; the rotating connector 2 is a universal ball, and the outer wall of the rotating connector 2 is in a penetrating rotational connection with the middle section of the front positioning frame 3, and a spherical hole groove structure is arranged at the connection part between the front positioning frame 3 and the outer wall of the rotating connector 2; the horizontal adjustment mechanism includes a hydraulic telescopic member 101 fixed on the side of the vehicle frame 1, the end of the output shaft of the hydraulic telescopic member 101 is fixed with a sliding block 102, the sliding block 102 is in a penetrating sliding connection with the front positioning frame 3, and the inside of the side of the vehicle frame 1 is hollow, and a first motor screw rod assembly 103 is further fixed in the middle of the hollow part, and a liquid seal plate 104 is sleeved on the outer wall of the output shaft of the first motor screw rod assembly 103;

[0049] Among them, a fitting type of sealed sliding connection is formed between the liquid seal plate 104 and the inner hollow inner wall of the side of the vehicle frame 1. There is oil in the inner part of the side of the vehicle frame 1 below the liquid seal plate 104 and inside the hydraulic telescopic member 101, and the two are interconnected through a pipeline. The sliding block 102 is arranged in a "work" - shaped structure composed of cylinders, and the through - hole of the front positioning frame 3 and the sliding block 102 is arranged in a strip - shaped structure. Moreover, the diameter of the middle section of the "work" - shaped front positioning frame 3 is equal to the width of the through - hole on the front positioning frame 3;

[0050] Moreover, the diameter of the middle section of the "work" - shaped front positioning frame 3 is smaller than the length of the through - hole on the front positioning frame 3. At the same time, the front positioning frame 3, the sliding block 102 and the hydraulic telescopic member 101 are located in the same vertical projection plane;

[0051] When the above - mentioned technical solution is used, after the leveling mechanism is placed and positioned stably, by using the first motor - lead screw assembly 103, during its operation, it drives the liquid seal plate 104 to rise and fall inside the vehicle frame 1 by means of a threaded connection. Driven by the rise and fall of the liquid seal plate 104, the oil in the vehicle frame 1 communicates with the oil in the hydraulic telescopic member 101 under the action of the pipeline, so as to quickly control the telescopic movement of the hydraulic telescopic member 101. The sliding block 102 at the output shaft end rises and falls, and the sliding of the sliding block 102 and the strip - shaped through - hole on the side of the front positioning frame 3 causes the front positioning frame 3 to tilt around the connection of the rotating connector 2, adjusting the horizontal state of the installation of the front positioning frame 3. When leveling the front positioning frame 3, its horizontal calibration can be carried out through the level bubble 4 at the top of the front positioning frame 3. When the front positioning frame 3 is positioned horizontally, the bottom bracket 5, the movable cross - bar 6 and the front scraper 7 installed at its bottom are positioned horizontally, maintaining a good horizontal state.

[0052] Embodiment 3: As Figure 1 and Figure 7 and Figure 8 shown, the present invention also discloses a lifting and adjusting member of the ground leveling mechanism and a method for leveling operation, and the specific content is as follows:

[0053] The bottom bracket 5 is movably installed at the lower end of the front positioning frame 3, and a lifting and adjusting member is fixed in the middle of the front positioning frame 3 for changing the overall positioning height of the bottom bracket 5. The bottom of the bottom bracket 5 is movably installed through - hole with a movable cross - bar 6. The front end of the movable cross - bar 6 is bolt - fixed with a front scraper 7. At the same time, a laser 8 is fixed at the top of the end of the front scraper 7 for horizontal calibration. The lifting and adjusting member includes a motor - chain belt assembly 10 at the middle of the bottom of the front positioning frame 3, and positioning rotating cylinders 11 are also rotatably installed through bearings inside the left and right sides of the front positioning frame 3. The outer wall of the positioning rotating cylinder 11 is connected with the motor - chain belt assembly 10;

[0054] And a vertical lead screw 12 is threadedly connected through the middle of the positioning drum 11. The lower end of the vertical lead screw 12 is fixedly connected to the upper end of the bottom bracket 5. Moreover, the upper end of the vertical lead screw 12 is arranged in a rectangular block structure, and this rectangular block structure is arranged in a sliding connection with the inner wall of the bottom bracket 5 that is radially engaged and axially fitted;

[0055] In the use of the above technical solution, with the front positioning frame 3 horizontally positioned, according to the requirements of the beam and slab pouring dimensions of the construction site, the positioning drum 11 can be driven to rotate by the motor chain belt assembly 10. Utilizing the threaded connection between the positioning drum 11 and the vertical lead screw 12, the vertical lead screw 12 and the bottom bracket 5 are driven to lift, changing the distance between the bottom of the front scraper 7 and the beam and slab formwork of the construction site. During the process, the laser 8 on the front scraper 7 can be compared with the one-meter line point of the construction setting-out to ensure the accuracy of the ground thickness when the leveling mechanism levels the ground; after the concrete is poured and vibrated between the steel bar meshes on the beam and slab, the front scraper 7 is driven to move back and forth by the movable cross bar 6. While the front scraper 7 levels the concrete on the building ground, the required size and thickness of the ground beam and slab are formed, and the operation is convenient.

[0056] Embodiment 4: On the basis of Embodiment 3, the present invention also as Figures 9-11 shown, discloses the driving mode of the leveling mechanism, and the specific content is as follows:

[0057] The movable cross bar 6 is arranged in a segmented structure, and the two are threadedly connected through. Moreover, the movable cross bar 6 and the bottom bracket 5 are arranged in a through sliding installation structure. The movable cross bar 6 and the front scraper 7 are vertically distributed, and adjacent front scrapers 7 are positioned and installed by bolts; and a connecting head 9 is fixed at the end of the movable cross bar 6 away from the front scraper 7;

[0058] In the above technical solution, both the movable cross bar 6 and the front scraper 7 are arranged in a segmented structure. When leveling the ground, the lengths of the movable cross bar 6 and the front scraper 7 can be adjusted according to the different lengths of the construction ground, so as to be suitable for leveling the ground in different ranges and scales;

[0059] At the same time, the connecting head 9 is threadedly connected with a first pushing handle 901, and the first pushing handle 901 is arranged in a "Y" - shaped structure; the connecting head 9 is threadedly connected with a second pushing handle 902, the second pushing handle 902 corresponds to the connecting head 9 one by one, and the second pushing handle 902 is arranged in a folded "L" - shaped;

[0060] As Figure 10 and Figure 11As shown in the figure, when leveling the building floor with a small span on the opposite side, the frictional reaction force between the front scraper 7 and the concrete on the building floor is small. With the installation of the first push handle 901, the front scraper 7 can be driven to move by the movable cross bar 6 under single-person operation for floor leveling. When leveling the building floor with a large span on the opposite side, the frictional reaction force between the front scraper 7 and the concrete on the building floor is large. At this time, with the installation of the second push handle 902 and under multi-person operation, the front scraper 7 can be moved for floor leveling.

[0061] Meanwhile, a shaped groove is provided at the center of the top of the vehicle frame 1. A mobile power source is installed in the shaped groove in a snap-fit manner for supplying energy to the electrical components in the leveling mechanism. And a control switch is provided on the handle of the vehicle frame 1 for starting and stopping the electrical components in the leveling mechanism. In the above technical solution, the electrical components can be driven through the switch mechanism, with convenient operation and facilitating the use of the leveling mechanism.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
