Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete fixing frame for building construction. Background Technology

[0002] Concrete is a man-made building material made of cement, sand, crushed stone or other coarse aggregates, and water. It is commonly used in building and foundation engineering and is widely used because of its strength, durability, low cost, and ease of shaping.

[0003] Current concrete fixing frames, such as the Chinese patent application CN202421258502.X which discloses a concrete fixing frame for building construction, include a base and a bottom plate set above the base. The bottom plate has supporting legs on its lower side and is mounted on the upper end of the supporting legs. A rotatably connected support frame is located on the upper side of the bottom plate, and a top plate is located between the bottom plate and the support frame. Support columns are fixedly installed on the outer side of the bottom plate, and the upper end of the support columns has a threaded rod. The outer side of the support frame has a first side plate and a second side plate rotatably connected, and one end of the threaded rod is rotatably connected to one side of the corresponding first and second side plates. A fixing element is fixedly installed at one end of the support frame. While these methods allow for concrete pouring and easy disassembly of concrete slabs, they lack an auxiliary leveling function after concrete pouring, increasing the workload during subsequent leveling work. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a concrete fixing frame for building construction, which can initially scrape the poured concrete, reduce the amount of subsequent manual leveling work, and improve the quality of the concrete surface.

[0005] The technical solution adopted by this utility model is: a concrete fixing frame for building construction, including a base, a bottom plate set above the base, a support frame rotatably connected to the upper side of the bottom plate, a first side plate and a second side plate rotatably connected to the outer side of the support frame, and an auxiliary leveling mechanism for leveling concrete; the auxiliary leveling mechanism includes an L-shaped fixing block set at the corner of the support frame, a vertically upward fixing column set at the top corner of the fixing block, a guide slide rod set between two fixing columns on the same side, two guide slide rods are provided, and the two guide slide rods are arranged opposite each other, a movable connecting plate is slidably connected between the two guide slide rods, a scraping plate is set on one side of the movable connecting plate, movable sliders are set at both ends of the movable connecting plate, guide sliding holes for the guide slide rods to pass through are opened on the movable sliders, and a push-pull handle is connected to the top center of the movable connecting plate through a rotating shaft.

[0006] Preferably, a height adjustment component for adjusting the height of the scraper plate is provided between the two fixed columns on the same side. There are two height adjustment components, and the two height adjustment components are arranged opposite to each other.

[0007] Preferably, the height adjustment component includes an L-shaped adjustment slide hole on the fixed column, and both ends of the guide slide rod are provided with adjustment sliders that cooperate with the adjustment slide hole.

[0008] Preferably, the height adjustment assembly further includes a fixed connecting plate disposed between two adjacent fixed columns, an adjusting screw is threadedly connected to the middle of the fixed connecting plate, and a lifting connecting plate is connected to the bottom end of the adjusting screw via a bearing.

[0009] Preferably, both ends of the lifting connecting plate are connected to the other end of the adjusting slider, and the top of the adjusting screw is provided with a rotating wheel.

[0010] Preferably, the scraper plate is connected to one side of the movable connecting plate via a rotating shaft, and the movable connecting plate is provided with an angle fine-tuning component for adjusting the angle of the scraper plate.

[0011] Preferably, the angle fine-tuning component includes a fine-tuning screw threaded to the upper end of the movable connecting plate and connected to the scraper plate via a bearing, and a horizontally arranged fixed connecting rod at the lower end of the movable connecting plate. The end of the fixed connecting rod is connected via a pivot to a fine-tuning connecting rod connected via a pivot to the middle of the scraper plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting an auxiliary leveling mechanism at the top of the support frame, the push-pull handle can be manually pushed and pulled. The push-pull handle drives the moving connecting plate along the guide slide through the rotating shaft. The moving connecting plate drives the scraper plate to move, which can initially level the poured concrete, reduce the amount of subsequent manual leveling work, and improve the quality of the concrete surface.

[0014] 2. By adding a height adjustment component based on Example 1, rotating the wheel drives the adjustment screw to rotate. The adjustment screw is threadedly connected to the fixed connecting plate, and one end of the adjustment screw is connected to the lifting connecting plate via a bearing. Under the cooperation of the adjustment slider and the adjustment sliding hole, the adjustment slider moves up and down, thereby causing the lifting connecting plate to move up and down. This makes the concrete fixing frame suitable for different components requiring different thicknesses of concrete paving, avoiding over-pressure or missed scraping caused by the fixed height of traditional screeds. It can also lower the height of the screed after the initial scraping for a second fine scraping, eliminating surface depressions caused by vibration settlement and ensuring the screed's leveling effect on the poured concrete.

[0015] 3. By adding an angle fine-tuning component based on Example 2, the fine-tuning screw is rotated and threadedly connected to the moving connecting plate. The fine-tuning screw drives the scraper plate to move through the rotating shaft, and under the action of the fine-tuning connecting rod, the scraper plate rotates around the end of the fixed connecting rod. The fine-tuning connecting rod swings synchronously. After the scraper plate is pushed from left to right to level the surface, the tilt angle of the scraper plate can be adjusted, and then the scraper plate can be pushed in the opposite direction. This allows the aggregate to be reset after tilting once and then pushed in the opposite direction, eliminating the orientation of the aggregate and improving the uniformity of the density of the poured concrete.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0026] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a concrete fixing frame for building construction, including a base 1, a base plate 2 disposed above the base 1, a support frame 3 rotatably connected to the upper side of the base plate 2, a first side plate 4 and a second side plate 5 rotatably connected to the outer side of the support frame 3, and support legs connected to the base 1 at the bottom corners of the base plate 2 (the base 1, base plate 2, support frame 3, first side plate 4 and second side plate 5 are all prior art). It also includes an auxiliary leveling mechanism 6 for leveling concrete; the auxiliary leveling mechanism 6 includes an L-shaped fixing block 601 disposed at the corner of the support frame 3, a vertically upward fixing column 602 disposed at the top corner of the fixing block 601, and a guide slide rod 603 disposed between two fixing columns 602 on the same side. Two guide slide rods 603 are provided. Two guide slide rods 603 are arranged opposite each other, and a movable connecting plate 604 is slidably connected between the two guide slide rods 603. One side of the movable connecting plate 604 is provided with a scraper plate 605, and both ends of the movable connecting plate 604 are provided with movable sliders 606. The movable sliders 606 are provided with guide holes for the guide slide rods 603 to pass through. The top center of the movable connecting plate 604 is connected to a push-pull handle 607 through a rotating shaft. By providing an auxiliary scraping mechanism 6 at the top of the support frame 3, the push-pull handle 607 is manually pushed and pulled. The push-pull handle 607 drives the movable connecting plate 604 to move along the guide slide rods 603 through the rotating shaft. The movable connecting plate 604 drives the scraper plate 605 to move, which can initially scrape the poured concrete, reduce the amount of subsequent manual leveling work, and improve the quality of the concrete surface.

[0027] The cross-section of the guide slide 603 can be circular or rectangular, preferably circular, which can improve the stability of the moving slider 606 moving along the guide slide 603. The length of the moving slider 606 is set to 3cm, which makes the movement stability of the moving slider 606 even higher.

[0028] Example 2, as Figure 4 and Figure 5As shown, a further improvement has been made based on Embodiment 1. A height adjustment assembly 7 for adjusting the height of the scraper plate 605 is provided between the two fixed columns 602 on the same side. Two height adjustment assemblies 7 are provided, and the two height adjustment assemblies 7 are arranged opposite each other. Each height adjustment assembly 7 includes an L-shaped adjusting sliding hole 701 opened on the fixed column 602. Both ends of the guide slide rod 603 are provided with adjusting sliders 702 that cooperate with the adjusting sliding hole 701. The height adjustment assembly 7 also includes a fixed connecting plate 703 provided between two adjacent fixed columns 602. An adjusting screw 704 is threadedly connected to the middle of the fixed connecting plate 703. The bottom end of the adjusting screw 704 is connected to a lifting connecting plate 705 via a bearing. Both ends of the lifting connecting plate 705 are provided with connections to the other end of the adjusting slider 702. The adjusting screw 704… The top is equipped with a rotating wheel. By adding a height adjustment component 7 based on Embodiment 1, rotating the rotating wheel drives the adjustment screw 704 to rotate. The adjustment screw 704 is threadedly connected to the fixed connecting plate 703. One end of the adjustment screw 704 is connected to the lifting connecting plate 705 via a bearing. Under the cooperation of the adjustment slider 702 and the adjustment sliding hole 701, the adjustment slider 702 moves up and down, thereby causing the lifting connecting plate 705 to move up and down. This makes the concrete fixing frame suitable for different components that require different thicknesses of concrete. It avoids over-pressure or missed scraping caused by the fixed height of the traditional scraper plate 605. After the initial scraping, the height of the scraper plate 605 can be lowered for a second fine scraping to eliminate surface depressions caused by vibration settlement and ensure the scraper plate 605 has a smoothing effect on the poured concrete. The rest of the structure is the same as in Embodiment 1.

[0029] Since the push-pull handle 607 is connected to the top center of the movable connecting plate 604 through a pivot, the scraper plate 605 can move left and right in both forward and reverse directions. The height of the fixed connecting plate 703 can be set according to the actual usage, and the height of the fixed connecting plate 703 will not affect the push-pull action of the push-pull handle 607.

[0030] Example 3, as Figure 5As shown, a further improvement has been made based on Embodiment 2. The angle fine-tuning component 8 includes a fine-tuning screw 801 threadedly connected to the upper end of the movable connecting plate 604 and connected to the scraper plate 605 via a bearing. The lower end of the movable connecting plate 604 is provided with a horizontally arranged fixed connecting rod 802. The end of the fixed connecting rod 802 is connected via a pivot to a fine-tuning connecting rod 803 connected via a pivot to the middle of the scraper plate 605. By adding the angle fine-tuning component 8 based on Embodiment 2, rotating the fine-tuning screw 801, which is threadedly connected to the movable connecting plate 604, allows the fine-tuning screw 801 to drive the scraper plate via the pivot. The scraper plate 605 moves and, under the action of the fine-tuning link 803, rotates around the end of the fixed link 802. The fine-tuning link 803 swings synchronously. After the scraper plate 605 is pushed from left to right to level the concrete, the inclination angle of the scraper plate 605 can be adjusted, and then the scraper plate 605 can be pushed in the opposite direction. This allows the concrete aggregate to be reset after tilting once and then pushed in the opposite direction, eliminating the orientation of the aggregate and improving the density and uniformity of the poured concrete. The inclination angle formed between the scraper plate 605 and the concrete contact surface is set to 5°-10° to facilitate the directional movement of the aggregate. The rest of the structure is the same as in Example 2.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
