Description

Technical Field

[0001] The present invention relates to the technical field of steel formwork, and particularly to a quick-assembly pile cap steel formwork. Background Art

[0002] The pile cap steel formwork is a high-strength steel structure formwork dedicated to pouring pile cap concrete, and is widely used in infrastructure construction such as buildings, bridges, and roads. Through precise size and shape design, it ensures the quality of concrete pouring and the structural stability of the pile cap.

[0003] When the steel formwork needs to be demolded, although a demolding agent is sprayed on the steel formwork in the early stage, if the demolding agent is unevenly applied or the quality of the demolding agent is poor, it will cause the steel formwork to adhere to the cement and be difficult to demold. When demolding difficulties occur, workers need to gradually perform demolding operations on the steel formwork from one side. However, since the steel formwork is a whole, the adhesion points of the steel formwork are all stressed simultaneously during demolding, making it very difficult to remove. At the same time, when assembling the existing steel formwork, workers need to use bolts to fasten the steel formwork for assembly, and the process of screwing bolts is very cumbersome, wasting a lot of construction time.

Detailed implementation manners

[0037] Mentioning an embodiment herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0038] Embodiment 1: When using steel formwork, if the release agent is used improperly or the quality of the release agent is poor, it will cause the steel formwork to adhere to the cement when the steel formwork is removed. Since the steel formwork is a whole, when removing the formwork, all the adhesion points with the cement are stressed simultaneously, making it very difficult to demold the steel formwork. At the same time, when the steel formwork is assembled and installed, it is fastened by bolts, and the number of bolts in the whole process is very large, resulting in very low assembly construction efficiency; the following implementation manners are adopted to solve the above problems.

[0039] A quick-installable pile cap steel formwork, as Figures 1-4As shown in the figure, it includes a first template 1; a second template 2, which is arranged on the right side of the first template 1, and the second template 2 is in contact with the first template 1 and is mirror-symmetrically distributed. Both the first template 1 and the second template 2 are provided with vertical and horizontal ribs to improve the strength of the first template 1 and the second template 2 and enhance the anti-deformation ability of the first template 1 and the second template 2; three hinges 3 are provided, and the three hinges 3 are fixedly connected to the joint between the first template 1 and the second template 2 for hinging between the first template 1 and the second template 2. When demolding, the first template 1 and the second template 2 can rotate around the hinge 3 to form a certain angle; two first connecting blocks 4 are provided, and the two first connecting blocks 4 are both fixedly connected to the right part of the first template 1. Two second fixing blocks 5 are fixedly connected to the second template 2. The first connecting block 4 and the adjacent second fixing block 5 are mirror-symmetrically distributed, and through holes are provided in the middle of both the first connecting block 4 and the second fixing block 5. Inclined surfaces are provided at the relative side edges of the first template 1 and the second template 2, and inclined surfaces are provided at the relative side edges of the first connecting block 4 and the second fixing block 5; the included angle formed by the inclined surfaces of the first template 1 and the second template 2 and the included angle formed between the first connecting block 4 and the second fixing block 5 are both not greater than 20°; two sliding pins 6 are provided, and the two sliding pins 6 are respectively slidably connected in the through holes of the two first connecting blocks 4. The first connecting block 4 is provided with an L-shaped guiding groove 7, and the guiding groove 7 communicates with the through hole of the first connecting block 4. A sliding grip 8 fixed to the sliding pin 6 is slidably connected in the guiding groove 7, and the guiding groove 7 is used to guide the position of the grip 8 to limit the sliding pin 6; a connecting component is arranged on the left side of the first template 1. The connecting component changes the traditional connection method and is used to fix the connection points between the first template 1 and the connected second template 2 at the same time.

[0040] In the above solution, it aims to solve the problem that it is difficult to demold between the steel template and the cement loading platform during demolding. Both the first template 1 and the second template 2 are made of high-strength steel, and the vertical ribs and horizontal ribs on the first template 1 and the second template 2 improve the anti-deformation ability of the first template 1 and the second template 2. In the initial state, the relative edges of the first template 1 and the second template 2 are in complete fit and there is no gap. The three hinges 3 and the two groups of first connecting blocks 4 and second fixing blocks 5 are alternately distributed. The sliding pin 6 is made of high-strength steel and has the ability to resist bending. The diameter of the sliding pin 6 is the same as the diameter of the through holes in the middle of the first connecting block 4 and the second fixing block 5, and the frictional resistance can be ignored when the sliding pin 6 slides along the first connecting block 4. The purpose is to ensure that the rear sides of the first template 1 and the second template 2 are in the same plane when using this steel template, improve the flatness of the cement on the outer side of the pile cap. The connecting component connects this steel template and completes the fixation of multiple points, not only ensuring the connection strength but also improving the assembly efficiency.

[0041] Specific working process: When assembling the steel formwork, the staff will successively pull the two sliding grips 8 to the right. The sliding grips 8 slide to the right along the guide grooves 7, and the sliding grips 8 drive the sliding pins 6 to insert into the through holes of the second fixing blocks 5. Then the staff swings the sliding grips 8, and the guide grooves 7 limit the positions of the sliding grips 8 to prevent the positions of the sliding pins 6 from shifting. The staff moves the same steel formwork to the left side of the first formwork 1, and then connects the second formwork 2 on the left side of the first formwork 1 through the connecting component. The connecting component can simultaneously fix multiple points on the first formwork 1 and the second formwork 2 on its left side, which not only improves the assembly speed of the steel formwork, but also makes the extrusion forces at each fixed position between the first formwork 1 and the second formwork 2 on its left side the same, preventing the generation of gaps between the steel formworks due to uneven force at the connection points and resulting in the outflow of cement slurry.

[0042] When disassembling the steel formwork, the staff resets the sliding grips 8 in sequence. At this time, the staff can choose a suitable tool to reset the sliding grips 8, thereby saving physical strength. At the same time, the staff successively releases the connection of the connecting component to the second formwork 2 on the left side. The staff pulls the first formwork 1 forward, and at this time, the first formwork 1 swings with the hinge 3 as the rotation point. After the inclined surfaces of the first formwork 1 and the second formwork 2 on the right side come into contact, the first formwork 1 and the second formwork 2 on the right side will not rotate relative to each other. At the same time, the inclined surfaces on the first connecting block 4 and the second fixing block 5 also come into contact with each other, successively demolding the second formwork 2, and peeling off the first formwork 1 and the second formwork 2 on the right side from the side wall of the loading platform like peeling paper, avoiding the invalidation of the release agent on the rear sides of the first formwork 1 and the second formwork 2, and causing the first formwork 1 and the second formwork 2 to adhere to the cement slurry on a large area and be difficult to demold.

[0043] Embodiment 2: On the basis of Embodiment 1, as Figure 2 、 Figures 5-7As shown in the figure, the connecting component includes: mounting seats 9, a total of ten are provided, and the ten mounting seats 9 are fixedly connected to the left side of the first template 1 at intervals. Both the first template 1 and the second template 2 are provided with through holes at intervals. The diameter of the through hole on the first template 1 is larger than that of the through hole on the second template 2, and the pitch of the through holes on the first template 1 and the second template 2 is the same. The through hole on the first template 1 communicates with the mounting seat 9; a sliding rod 10 is slidably connected in the through hole of the mounting seat 9 and the first template 1, and a notch is provided at the left end of the sliding rod 10; a rotating shaft 11 is rotatably connected in the notch of the sliding rod 10, and a limiting member 12 is fixedly connected to the rotating shaft 11. The limiting member 12 is square and is used for limiting cooperation with the connected second template 2. A torsion spring (not shown in the figure) is installed between the rotating shaft 11 and the sliding rod 10 to ensure that the limiting member 12 and the sliding rod 10 are in a parallel state. The height of the limiting member 12 is the same as the diameter of the sliding rod 10, which is convenient for the limiting member 12 and the sliding rod 10 to be inserted into the through hole of the connected second template 2. An elastic member is installed between the mounting seat 9 and the sliding rod 10, and fixing columns 13 are fixedly connected to both sides; ten wedge-shaped frames 14 are provided, and the ten wedge-shaped frames 14 are distributed at intervals on the left part of the first template 1. The wedge-shaped frames 14 are located between the mounting seats 9 and the fixing columns 13 on the sliding rod 10; a first sliding plate 15 is slidably connected to the vertical rib of the first template 1. The wedge-shaped frame 14 is fixedly connected to the first sliding plate 15. The first sliding plate 15 is provided with equally spaced square holes to adapt to the moving distance of the sliding rod 10. A first bolt 16 is threadedly connected to the first template 1, and the first bolt 16 is rotatably connected to the first sliding plate 15; an adjusting component is provided on the left side of the first template 1 to control the swinging angle of the limiting member 12.

[0044] As Figure 2 , Figure 5 and Figure 7 shown, the adjusting component includes: a second sliding plate 17, the second sliding plate 17 is slidably connected to the left side of the first template 1, and the length of the second sliding plate 17 is the same as the length of the vertical rib on the first template 1; ten pulling ropes 18 are provided, and the ten pulling ropes 18 are respectively located in the ten sliding rods 10. The pulling ropes 18 are elastic ropes, and the elastic force of the pulling ropes 18 is greater than the elastic force of the torsion spring between the rotating shaft 11 and the sliding rod 10. A groove is provided in the middle of the limiting member 12. The left end of the pulling rope 18 is fixedly connected to the rotating shaft 11, and the right end of the pulling rope 18 penetrates through the vertical rib of the first template 1 and is fixedly connected to the second sliding plate 17. An arc-shaped protrusion is provided in the middle of the rotating shaft 11, and the connection part of the pulling rope 18 and the rotating shaft 11 is located above the arc-shaped protrusion; a second bolt is rotatably connected to the second sliding plate 17, and the second bolt is threadedly engaged with the mounting plate of the vertical rib on the first template 1.

[0045] In the above solution, it aims to solve the problem that when assembling steel formwork, connecting the steel formwork by bolts increases the workload, and the forces exerted by each bolt on the steel formwork are different, resulting in different connection strengths at the fixed points of the steel formwork and causing gaps in the steel formwork. The mounting seat 9 is connected to the left side of the first formwork 1 by bolts or welding, and the number of mounting seats 9 changes according to the height change of the first formwork 1. The diameter of the sliding rod 10 is smaller than the through-hole diameter of the second formwork 2, while the length of the limiting member 12 is greater than the through-hole diameter of the second formwork 2. A metal sleeve is installed on the outer side of the fixed column 13 to reduce the friction between the fixed column 13 and the wedge-shaped frame 14. The wedge-shaped frame 14 is vertically arranged, and both the front and rear sides of the wedge-shaped frame 14 are wedge-shaped plates. A spline groove is provided on the outer side of the sliding rod 10, and splines are provided on the inner wall of the mounting seat 9. The mounting seat 9 is in spline fit with the sliding rod 10 to prevent the sliding rod 10 from twisting in the mounting seat 9. The first bolt 16 is rotatably connected to the center point of the upper side of the first sliding plate 15, so that the first sliding plate 15 is continuously subjected to an upward vertical pulling force. The first sliding plate 15 and the second sliding plate 17 are respectively located on both sides of the leftmost vertical rib of the first formwork 1. The second bolt is provided in the middle of the second sliding plate 17 and is perpendicular to the second sliding plate 17.

[0046] Specific working process: The staff places the steel formwork on the left side of the first formwork 1. At this time, the first formwork 1 will contact the second formwork 2 of the left-side steel formwork. The first formwork 1 and the second formwork 2 described below are in the above position relationship. Here, the assembly process of the first formwork 1 and the left-side second formwork 2 is described, and the position relationship will not be introduced below.

[0047] During the installation of the left-side steel formwork, the steel formwork is pushed to the right, so that the sliding rod 10 is inserted into the through-hole on the right side of the second formwork 2. The installation surface of the pile cap steel formwork is leveled by cement pouring. During the installation of the steel formwork, the steel formwork is installed on the upper side of the leveled cement, and the bottom of the steel formwork is in a flush state. Subsequently, the staff twists the second bolt (electric or manual) with a wrench. The second bolt uses the thread to pull the second sliding plate 17 to the right. The second sliding plate 17 moves to the right along the first formwork 1. The second sliding plate 17 simultaneously pulls ten pull ropes 18 to the right. Taking the uppermost pull rope 18 as an example; the pull rope 18 moves to the right along the sliding rod 10. The pull rope 18 pulls the rotating shaft 11, and the rotating shaft 11 rotates along the sliding rod 10. Since the left end of the pull rope 18 is connected to the uppermost side of the arc-shaped block on the rotating shaft 11, when the pull rope 18 is tightened, the rotating shaft 11 drives the limiting member 12 to rotate until the limiting member 12 rotates to the vertical state. At this time, the left end of the pull rope 18 has moved to the right side of the rotating shaft 11, and at the same time, the torsion spring is tightened. As the second sliding plate 17 moves to the right, the pull rope 18 is gradually stretched.

[0048] Subsequently, the staff used tools to rotate the first bolt 16. The first bolt 16 rotated and moved upward along the first template 1. The lower end of the first bolt 16 drove the first sliding plate 15 to move upward along the vertical rib of the first template 1. The first sliding plate 15 drove all the wedge-shaped frames 14 thereon to move upward. Taking the uppermost wedge-shaped frame 14 as an example; the wedge-shaped frame 14 upwardly squeezed the fixing columns 13 on the mounting seat 9 and the sliding rod 10. The adjacent fixing columns 13 on the left and right were squeezed by the wedge-shaped frame 14 and moved away from each other. The elastic member between the mounting seat 9 and the sliding rod 10 was stretched. The two fixing columns 13 on the right drove the sliding rod 10 to move to the right. The sliding rod 10 drove the limiting member 12 to move until the limiting member 12 abutted against the second template 2. During the process of the limiting member 12 moving to the right, the pulling rope 18 always maintained elasticity, thereby keeping the limiting member 12 in a vertical state. As the wedge-shaped frame 14 moved upward, the limiting member 12 applied a squeezing force to the second template 2 to the right, so that the right side of the second template 2 was closely attached to the left side of the first template 1. Subsequently, the staff stopped rotating the first bolt 16. Under the action of the thread, the first sliding plate 15 was located at this position, thereby ensuring the squeezing force of the limiting member 12 on the second template 2. By rotating the first bolt 16, the two steel templates were connected, thereby improving the assembly efficiency of the steel templates.

[0049] When the steel templates are removed and demolded, the staff first rotates the second bolt to move the second sliding plate 17 to the left to reset, releasing the tension state of the pulling rope 18 until the second sliding plate 17 is reset. Subsequently, the staff rotates the first bolt 16 in the reverse direction, so that the wedge-shaped frame 14 moves downward, and under the action of the elastic member, the sliding rod 10 moves to the left to reset. During the above process, under the elastic force of the torsion spring, the limiting member 12 gradually resets to the horizontal state, and then the two steel templates are separated.

[0050] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
