Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a heavy-duty building formwork with reinforced formwork corners. Background Technology

[0002] Construction formwork is a temporary support structure mainly used in the pouring process of concrete buildings. It is used to shape the shape of the building to be poured and bears the weight of the formwork itself and the load applied by the concrete during use. Therefore, the quality of construction formwork directly affects the quality of the building to be poured.

[0003] Construction formwork is prone to structural deformation during use due to the heavy loads it bears, leading to problems such as concrete leakage or insufficient local support causing building deformation. While strengthening the formwork material can effectively prevent deformation, structural deformation can still occur at the joints when formwork is spliced ​​at specific angles. Traditional methods primarily involve reinforcing these joints by fixing the formwork corners. However, since these corners are fixed, and there may be various angles for splicing formwork during casting, it is difficult to meet all usage requirements. For example, the patent application with publication number CN116201359A and patent name "A Formwork Connection Structure for Civil Engineering" uses a formwork corner reinforcement device that can adapt to different angles. However, the disadvantage of this reinforcement device is that it is directly fixed between two formwork panels, which means that enough space must be reserved between the formwork panels to insert and fix the reinforcement device. This limits the minimum angle that can be adapted. At the same time, the structure inside the angle must be thin enough to be inserted. This makes it difficult for the structural strength of the reinforcement structure to cope with high load conditions. It also lacks other designs that can improve the strength of the formwork support structure and reduce formwork deformation. Therefore, it is still difficult to meet the current usage requirements.

[0004] Therefore, we need a heavy-duty building formwork with reinforced corners to solve the problems that existing formwork corners cannot adapt to different angles and that the overall structural strength of the formwork is low and easily deformed, which can effectively improve the overall structural strength of the formwork. Summary of the Invention

[0035] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0036] Example 1: Please refer to Figures 1 to 4 The present invention provides a heavy building formwork with reinforced template corners, including a template body 1 and adjustable reinforced template corners 8. The template body 1 includes a template panel 104, and a side connecting plate 101 is fixedly installed at the edge of the template panel 104.

[0037] Please see Figures 1 to 4The adjustable reinforced template angle 8 includes two hinged mating plates 801, which are clamped between two adjacent template bodies 1. The adjustable reinforced template angle 8 also includes a pair of side connecting seats 802, which are bolted to side connecting plates 101 located on the two adjacent template bodies 1. The side connecting seats 802 are fixedly installed with a first sliding ring 806, and the first sliding ring 806 is slidably installed with an arc-shaped guide frame 804 and fixed by a fifth fixing screw 808. The axis of the arc-shaped guide frame 804 is located on the intersection line of the planes containing the edges of the two adjacent template bodies 1. A second sliding ring 807 is slidably installed on the arc-shaped guide frame 804 at each mating plate 801. A first threaded sleeve 805 is fixedly installed, and a first adjusting screw 803 for adjusting the distance between the second sliding ring 807 and the mating plate 801 is threaded onto the first threaded sleeve 805. The end of the first adjusting screw 803 is rotatably installed with the mating plate 801. A rotating mating seat 810 is rotatably installed on the second sliding ring 807, and a second adjusting screw 809 for adjusting the distance between the first sliding ring 806 and the second sliding ring 807 is rotatably installed on the rotating mating seat 810. A second threaded sleeve 811 is rotatably installed on the first sliding ring 806, and the second threaded sleeve 811 is threadedly installed with the second adjusting screw 809. When the edges of the two template bodies 1 are fitted at any angle, the adjustable reinforcing template corner 8 can be used to reinforce the template. The angle between the two template bodies 1 is reinforced. Specifically, the two side connecting seats 802 are first fixed to the side connecting plates 101 of the corresponding template bodies 1. At this time, the arc-shaped guide frame 804 is inserted into the two first sliding rings 806. The two template bodies 1 can be regarded as hinged. The axis of the arc-shaped guide frame 804 can be regarded as the hinge axis of the two template bodies 1. Moreover, this axis is also the intersection line of the planes where the edges of the two template bodies 1 are located. That is to say, when the edges of the two template bodies 1 need to contact each other to form the required angle, the contact position of the edges of the two template bodies 1 can be determined by the axis of the arc-shaped guide frame 804. Generally, this contact position is designed at the edge line of the front face of the template plate 104, thereby ensuring... To minimize the contact gap when the two template bodies 1 are installed at an angle, the angle between them can be changed simply by continuing along the arc-shaped guide frame 804 and the first sliding ring 806. Then, by rotating the second adjusting screw 809, the position of the second sliding ring 807 on the arc-shaped guide frame 804 is changed, allowing the outer surfaces of the two mating plates 801 to fit against and remain parallel to the side connecting plate 101. Next, by rotating the first adjusting screw 803, the hinge points of the two mating plates 801 are pressed towards the contact points of the two template bodies 1 until they can no longer move. At this point, the contact points of the two template bodies 1 are reinforced by the adjustable reinforcing template angle 8.Simultaneously, the gap between the two formwork bodies 1 is sealed by the mating plate 801, thus preventing concrete leakage. Furthermore, the adjustable reinforcing formwork angle 8 can accommodate installation of the two formwork bodies 1 at any angle, thus broadening its applicability and versatility.

[0038] Please see Figure 1 , Figure 2 , Figure 9 and Figure 11The rear end of the template body 1 is provided with a direction adjustment device 6 for adjusting the tilt angle of the template body 1 during installation. The direction adjustment device 6 includes a connecting base 612 fixedly installed on the template surface 104, and a rotating sleeve 607 is fixedly installed on the connecting base 612. The rotating sleeve 607 is rotatably installed with the rotating connecting seat 611. The rotating connecting seat 611 can be directly fixedly installed with the external scaffolding. An insert sleeve 608 for fixing the rotating sleeve 607 and the rotating connecting seat 611 is inserted into the rotating connecting seat 611. The inner sides of the rotating sleeve 607 and the rotating connecting seat 611 are respectively provided with matching insert grooves 610. The insert sleeve 608 is integrally formed with insert grooves located on the rotating sleeve 607 and the rotating connecting seat 611. The slot 610 is simultaneously fitted with the insertion protrusion 609. A rotating arm 603 for adjusting the insertion position of the insertion sleeve 608 is hinged to the connecting base 612. The connecting base 612 has a locking groove 601 for housing the rotating arm 603. An elastic piece 606 is fixedly installed in the locking groove 601. The elastic piece 606 can be a metal spring. A positioning hole 602 for locking the elastic piece 606 is provided in the rotating arm 603. A sliding groove 604 is provided on the rotating arm 603, and a sliding rod 605 that slides along the sliding groove 604 is fixedly installed on the insertion sleeve 608. When it is necessary to change the installation angle of the template body 1, the insertion sleeve 608 can be pulled out from the rotating sleeve 607 first, and then the rotating sleeve 608 can be rotated. 7. This creates the required angle between the rotating sleeve 607 and the rotating connecting seat 611. This angle determines the installation angle of the template body 1. Then, the insertion sleeve 608 is reinserted into the rotating sleeve 607, ensuring that the insertion protrusion 609 on the insertion sleeve 608 simultaneously engages with the insertion grooves 610 on both the rotating sleeve 607 and the rotating connecting seat 611. This fixes the rotating sleeve 607 and the rotating connecting seat 611 at this position, maintaining the angle between them. The operator can use the rotating arm 603 to pull out and insert the insertion sleeve 608. Specifically, when it is necessary to pull the insertion sleeve 608 out of the rotating sleeve 607, the operator can... As the rotating arm 603 is pulled out of the locking groove 601, the elastic plate 606 is deformed by the force and slides out of the positioning hole 602, escaping its fixed position on the rotating arm 603. Subsequently, as the rotating arm 603 continues to rotate, it pushes the sliding rod 605 outward. As the sliding rod 605 moves along the sliding groove 604, it can pull the insertion sleeve 608 outward. When the insertion sleeve 608 needs to be inserted, the rotating arm 603 is pushed in the opposite direction, causing it to enter the locking groove 601. Simultaneously, the elastic plate 606 engages with the positioning hole 602, thus fixing the rotating arm 603 and preventing it from rotating spontaneously. During the process of the rotating arm 603 returning to the locking groove 601...The sliding rod 605 will also cause the insertion sleeve 608 to be inserted into the desired position.

[0039] Please see Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 The rotating connecting seat 611 is provided with an adjusting device 5 for adjusting the front and rear positions of the template body 1. The adjusting device 5 includes an intermediate connecting plate 503 rotatably mounted to the rotating connecting seat 611. The rear end of the intermediate connecting plate 503 is provided with a sliding connecting seat 505 that can be directly fixed to the scaffolding. A first guide rod 504 is fixedly mounted on the sliding connecting seat 505 and slidably mounted to the intermediate connecting plate 503. The intermediate connecting plate 503 is connected to the first guide rod 504 by a fourth fixing screw 502. A fine-tuning angle device 3 for adjusting the rotation angle of the template body 1 is provided between the fixed installation, the distance adjustment device 5, and the direction adjustment device 6. The fine-tuning angle device 3 includes a worm gear 302 rotatably mounted on a rotating connecting seat 611, and a handwheel 301 coaxially fixedly mounted on the worm gear 302. A worm wheel 303 meshing with the worm gear 302 is rotatably mounted on the rotating connecting seat 611, and a drive wheel 304 coaxially mounted on the worm wheel 303. A drive wheel 304 meshing with the drive wheel 304 is fixedly mounted on the intermediate connecting plate 503. When the front and rear positions of the template body 1 need to be adjusted, the first guide rod 504 only needs to be slid back and forth along the middle connecting plate 503, and then re-fixed at the new position by the fourth fixing screw 502. Since the direction adjustment device 6 can only change the tilt angle of the template body 1 in one direction, when the required tilt direction of the template body 1 is not in that direction, it needs to be finely adjusted by the angle fine adjustment device 3. Specifically, the worm 302 can be rotated by turning the handwheel 301, and then the worm 302 will drive the worm wheel 303 to rotate, and the worm wheel 303 will drive the drive wheel 304 to rotate. The drive wheel 304 is in a meshing state with the gear ring 501. When the drive wheel 304 rotates, it can drive the template body 1 to rotate along the central axis of the gear ring 501. At this time, the template body 1 can be adjusted to the required angle, and then the direction adjustment device 6 can be used to adjust the direction of the template body 1. At this time, the template body 1 can be installed in the required position.

[0040] Please see Figure 1 , Figure 2 , Figure 9 and Figure 10The sliding connecting seat 505 is provided with a clamping and fixing device 4 for fixing to the scaffold. The clamping and fixing device 4 includes a sliding table 404 fixed to the sliding connecting seat 505. The sliding table 404 is provided with a V-shaped locking block 403 that mates with the scaffold. A second fixing screw 401 is screwed onto the sliding table 404. A sliding clamping block 402 is rotatably installed at the end of the second fixing screw 401, which, together with the V-shaped locking block 403, clamps the scaffold. The sliding clamping block 402 slides on the sliding table 404. The sliding connecting seat 505 is fixedly mounted with a second guide rod 506, and a sliding table 404 is slidably mounted on the second guide rod 506. A third fixing screw 405 is screwed onto the sliding table 404, and the third fixing screw 405 is used to fix the sliding table 404 and the second guide rod 506 together by compression. When it is necessary to adjust the vertical position of the template body 1, it is only necessary to make the sliding table 404 and the second guide rod 506 slide relative to each other, and then fix them together at the new position by the third fixing screw. The screw 405 can be re-fixed. When it is necessary to fix the scaffolding with the clamping and fixing device 4, the scaffolding can be aligned with the V-shaped clip 403 first, and then the second fixing screw 401 can be rotated so that the second fixing screw 401 can drive the sliding clamping block 402 to clamp the scaffolding between the sliding clamping block 402 and the V-shaped clip 403. In this way, the scaffolding can be fixed with the clamping and fixing device 4. The clamping and fixing device 4 does not necessarily have to be fixed with the scaffolding. It can also be clamped and fixed with other structures that can be fixed. It is only necessary to prevent the template body 1 from shaking after the clamping and fixing device 4 is clamped and fixed. In addition, after the template body 1 is fixed with other template bodies 1, the orientation of the clamping and fixing device 4 can also be adjusted in the opposite direction by the angle fine adjustment device 3, so that the clamping and fixing device 4 can be fixed with scaffolding arranged in other directions, instead of only being able to be fixed with scaffolding arranged in the horizontal direction, thus facilitating the installation of the template body 1.

[0041] The heavy-duty building formwork designed in this embodiment can reinforce the connection between the formwork bodies 1 through the adjustable reinforcing formwork angle 8, and can adapt to different included angles. It can also achieve structural reinforcement and angle adjustment of the formwork body 1 through the angle fine-tuning device 3, clamping and fixing device 4, distance adjustment device 5 and direction adjustment device 6, thereby facilitating the installation of the formwork body 1, improving the structural strength of the formwork body 1, ensuring the performance of the formwork body 1, solving the problem that the existing formwork angle cannot adapt to different included angles and the overall structural strength of the formwork is low and easy to deform, and can effectively improve the overall structural strength of the formwork.

[0042] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 Based on Embodiment 1, two adjacent directly connected template bodies 1 are fixed together by a splicing and fixing device 7. The splicing and fixing device 7 includes a C-shaped clamping plate 703 that is simultaneously clamped onto the side connecting plates 101 of the two adjacent template bodies 1. The C-shaped clamping plate 703 and the side connecting plates 101 are fixedly connected by a fixing rod 701. A push plate 705 is fixedly installed at the end of the fixing rod 701. The push plate 705 and the C-shaped clamping plate 703 are connected by a return spring 702. A positioning block 103 is integrally formed on the side connecting plate 101. A positioning groove 706 is opened on the inner side of the C-shaped clamping plate 703 to be inserted and clamped to the positioning block 103. A handle 704 is fixedly installed on the C-shaped clamping plate 703 to facilitate the handling of the splicing and fixing device 7. A reinforcing rib plate 102 is fixedly installed between 04 and the side connecting plate 101. When two adjacent template bodies 1 only need to be directly connected in parallel, they can be fixed by splicing and fixing device 7. At this time, it is only necessary to insert the side connecting plates 101 of the two adjacent template bodies 1 into the C-shaped clamping plate 703 at the same time, and then use the fixing rod 701 to fix the two side connecting plates 101 in the C-shaped clamping plate 703. At this time, the return spring 702 will squeeze the fixing rod 701 under its own contraction and always keep it in the clamping state of the side connecting plate 101, avoiding the automatic fall off of the fixing rod 701. This further solves the problem that the existing template corners cannot adapt to different included angles and the overall structural strength of the template is low and easy to deform, which can effectively improve the overall structural strength of the template.

[0043] Example 3: Please refer to Figure 1 , Figure 2 and Figure 8 Based on Embodiment 2, auxiliary fixing devices 2 for connecting external scaffolding are fixedly installed at the four corners of the template panel 104. The auxiliary fixing device 2 includes a ball head rod 201 hinged to the template panel 104, and the other end of the ball head rod 201 is hinged to the hinge seat 202. The hinge seat 202 and the C-shaped clip 203 are integrally formed, and the C-shaped clip 203 is fixed to the scaffolding by a first fixing screw 204. By fixing the C-shaped clip 203 to the external scaffolding, the template body 1 can be effectively fixed. The auxiliary fixing device 2 can also be adapted to scaffolding with different orientations, thus having good versatility. It further solves the problem that the existing template corners cannot be adapted to different angles and the overall structural strength of the template is low and easy to deform, which can effectively improve the overall structural strength of the template.

[0044] Example 4: Based on Example 3, the present invention also provides a method for using heavy-duty building formwork with reinforced corners, including the following steps:

[0045] Step 1: First, measure and draw the dimensions of the building to be poured with concrete at the construction site. Then, correctly erect the scaffolding. Next, place the bottom layer of the formwork body 1 in the corresponding position and fix it to the corresponding scaffolding using the clamping and fixing device 4. Then, adjust the installation position of the formwork body 1 using the angle fine-tuning device 3, the distance adjustment device 5, and the direction adjustment device 6. Then, fix the two adjacent formwork bodies 1 using the splicing and fixing device 7 and the adjustable reinforced formwork corner 8. Finally, fix the formwork body 1 to the scaffolding using the auxiliary fixing device 2.

[0046] Step 2: After the bottommost template body 1 is fixed, additional template bodies 1 can be added upwards based on this template body 1. At this time, the angle fine-tuning device 3, clamping and fixing device 4, distance adjustment device 5, and direction adjustment device 6 do not need to be installed on the template body 1. Instead, it can be directly fixed to the adjacent template body 1 through the splicing fixing device 7 and the adjustable reinforced template corner 8, and then fixed to the scaffolding through the auxiliary fixing device 2. Only when the installation position of the template body 1 of a certain layer needs to be changed, it is necessary to install the angle fine-tuning device 3, clamping and fixing device 4, distance adjustment device 5, and direction adjustment device 6 on the template body 1 to adjust the installation position of the template body 1.

[0047] Step 3: After the concrete pouring is completed, the main body of each layer of formwork 1 can be removed from top to bottom. At this time, the angle fine adjustment device 3, clamping and fixing device 4, distance adjustment device 5 and direction adjustment device 6 should be removed first. Then the splicing and fixing device 7 should be removed, followed by the adjustable reinforced formwork corner 8. Finally, the auxiliary fixing device 2 should be removed and the main body of the formwork 1 can be taken off.
