Description

Technical Field

[0001] The invention relates to the technical field of steel formworks, and in particular to a quick-installation pile cap steel formwork. Background Art

[0002] Pile cap steel formwork is a high-strength steel structure formwork specially used for pouring pile cap concrete. It is widely used in infrastructure construction such as buildings, bridges, roads, etc. It ensures the quality of concrete pouring and the structural stability of the cap through precise size and shape design.

[0003] When the steel membrane plate needs to be demoulded, although the demoulding agent will be sprayed on the steel formwork in the early stage, if the demoulding agent is not evenly applied or the quality of the demoulding agent is poor, it will cause the steel formwork to stick to the cement and make it difficult to demould. When demoulding is difficult, the staff will need to gradually demould the steel formwork from one side. However, since the steel formwork is a whole, the adhesion points of the steel membrane plate are all subjected to force at the same time during demoulding, making it difficult to remove. At the same time, when assembling the existing steel formwork, the staff need to assemble the steel formwork by bolting. The process of tightening the bolts is very cumbersome and wastes a lot of construction time. Summary of the invention

[0020] An adjusting component is arranged on one side of the first template and is used to control the swing angle of the limiting member.

[0021] Furthermore, the first sliding plate is provided with equally spaced square holes for accommodating the moving distance of the sliding rod.

[0022] Furthermore, a torsion spring is installed between the rotating shaft and the sliding rod to ensure that the limiting member and the sliding rod are in a parallel state.

DETAILED DESCRIPTION

[0037] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may 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, the steel formwork will adhere to the cement when it is removed. Since the steel formwork is an integral whole, all adhesion points with the cement are subjected to force at the same time when the formwork is removed, making it very difficult to demold the steel formwork. At the same time, when the steel formwork is assembled and installed, bolts are used to fasten and assemble it. The number of bolts in the whole process is very large, resulting in very low assembly construction efficiency. The above problems are solved by adopting the following implementation method.

[0039] A quick-install pile cap steel formwork, such as Figure 1-Figure 4As shown, 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 and the first template 1 are in contact and distributed in a mirror image, and the first template 1 and the second template 2 are both provided with vertical and horizontal ribs for improving the strength of the first template 1 and the second template 2, and enhancing 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, and are used to hinge the first template 1 and the second template 2. When demoulding, the first template 1 and the second template 2 can rotate around the hinges 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, and the second template 2 is fixedly connected to two second fixing blocks 5, and the first connecting block 4 and the adjacent second fixing block 5 are distributed in a mirror image, and the middle parts of the first connecting block 4 and the second fixing block 5 are both provided with There are through holes, and the first template 1 and the second template 2 are both provided with inclined surfaces at the opposite side edges, and the first connecting block 4 and the second fixed block 5 are both provided with inclined surfaces at the opposite side edges; the angle formed by the inclined surfaces of the first template 1 and the second template 2 and the angle formed between the first connecting block 4 and the second fixed block 5 are not greater than 20°; there are two sliding pins 6, and the two sliding pins 6 are respectively slidably connected in the through holes of the two first connecting blocks 4, and the first connecting block 4 is provided with an L-shaped guide groove 7, which is connected to the through hole of the first connecting block 4, and a sliding handle 8 fixed to the sliding pin 6 is slidably connected in the guide groove 7, and the guide groove 7 is used to guide the position of the handle 8 so as to limit the sliding pin 6; a connecting component, which is arranged on the left side of the first template 1, and the connecting component changes the traditional connection method and is used to simultaneously fix the connection point between the first template 1 and the connected second template 2.

[0040] In the above scheme, the problem that the steel formwork is difficult to demold from the cement bearing platform during demolding is solved. The first formwork 1 and the second formwork 2 are both made of high-strength steel, and the vertical ribs and transverse ribs on the first formwork 1 and the second formwork 2 improve the deformation resistance of the first formwork 1 and the second formwork 2. In the initial state, the relative edges of the first formwork 1 and the second formwork 2 are in a completely fitted state, 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 anti-bending ability. The diameter of the sliding pin 6 is the same as the diameter of the through hole in the middle of the first connecting block 4 and the second fixing block 5, and the friction resistance of the sliding pin 6 when sliding along the first connecting block 4 can be ignored. The purpose is to ensure that the rear side surfaces of the first formwork 1 and the second formwork 2 are in the same plane when the steel formwork is used, and to improve the flatness of the cement on the outside of the pile cap. The connecting component connects the steel formwork and completes the multi-point fixation, which not only ensures the connection strength but also improves the assembly efficiency.

[0041] Specific work flow: When assembling the steel formwork, the staff will pull the two sliding handles 8 to the right in turn, and the sliding handle 8 will slide to the right along the guide groove 7, and the sliding handle 8 will drive the sliding pin 6 to insert into the through hole of the second fixed block 5, and then the staff will swing the sliding handle 8, so that the guide groove 7 will limit the position of the sliding handle 8 to prevent the position of the sliding pin 6 from shifting. The staff will move the same steel formwork to the left side of the first formwork 1, and then connect the second formwork 2 on the left side of the first formwork 1 through the connecting assembly. The connecting assembly can fix the first formwork 1 and the second formwork 2 on its left side at multiple points at the same time, which not only improves the assembly speed of the steel formwork, but also the same extrusion pressure at each fixed position between the first formwork 1 and the second formwork 2 on its left side, which prevents the problem of uneven force on the connection points from causing gaps between the steel formworks and causing cement slurry to flow out.

[0042] When removing the steel formwork, the staff will reset the sliding handle 8 in turn. At this time, the staff can choose a suitable tool to reset the sliding handle 8, thereby saving physical strength. At the same time, the staff will release the connection of the connecting assembly to the second formwork 2 on the left side in turn, and the staff will pull the first formwork 1 to the front side. At this time, the first formwork 1 swings with the hinge 3 as the rotation point. After the first formwork 1 and the inclined surface of the second formwork 2 on the right side 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 fixed block 5 also contact each other, and the second formwork 2 is demoulded in turn, and the first formwork 1 and the second formwork 2 on the right side are peeled off from the side wall of the loading platform like peeling paper, thereby avoiding the failure of the release agent on the back side of the first formwork 1 and the second formwork 2, which causes the first formwork 1 and the second formwork 2 to adhere to the cement slurry over a large area and be difficult to demould.

[0043] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 5-Figure 7As shown, the connecting component includes: a mounting seat 9, which is provided with ten in total. The ten mounting seats 9 are fixedly connected to the left side of the first template 1 at intervals. The first template 1 and the second template 2 are both provided with through holes at intervals. The diameter of the through hole on the first template 1 is larger than the diameter of the through hole of the second template 2, and the spacing between the through holes on the first template 1 and the second template 2 is the same. The through hole of the first template 1 is connected with the mounting seat 9; a sliding rod 10 is slidably connected in the mounting seat 9 and the through hole of the first template 1, and a notch is provided at the left end of the sliding rod 10; a rotating shaft 11, the rotating shaft 11 is rotatably connected in the notch of the sliding rod 10, the rotating shaft 11 is fixedly connected to a limiting member 12, the limiting member 12 is set to a square shape, and the limiting member 12 is used to cooperate with the connected second template 2 in a limiting manner. 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 limit member 12 is the same as the diameter of the sliding rod 10, which is convenient for the limit member 12 and the sliding rod 10 to be inserted into the through hole connected to the second template 2. An elastic member is installed between the mounting seat 9 and the sliding rod 10, and fixed columns 13 are fixed on both sides; there are ten wedge frames 14, which are distributed at intervals on the left part of the first template 1, and the wedge frames 14 are located between the mounting seat 9 and the fixed columns 13 on the sliding rod 10; the first sliding plate 15 is slidably connected to the vertical ribs of the first template 1, the wedge frames 14 are fixed to the first sliding plate 15, and the first sliding plate 15 is provided with equally spaced square holes for adapting to the moving distance of the sliding rod 10, and the first template 1 is threadedly connected with a first bolt 16, and the first bolt 16 is rotatably connected to the first sliding plate 15; an adjusting component is arranged on the left side of the first template 1 to control the swing angle of the limit member 12.

[0044] like Figure 2 , Figure 5 and Figure 7 As shown, the adjusting component includes: a second sliding plate 17, which 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; a pull rope 18, of which ten are provided, and the ten pull ropes 18 are respectively located in ten sliding rods 10, the pull rope 18 is set as an elastic rope, and the elastic force of the pull rope 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 limit member 12, the left end of the pull rope 18 is fixedly connected to the rotating shaft 11, the right end of the pull rope 18 passes through the vertical rib of the first template 1, and the right end 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 between the pull rope 18 and the rotating shaft 11 is located at the upper part of the arc-shaped protrusion; a second bolt 19, which is rotatably connected to the second sliding plate 17, and the second bolt 19 is threadedly matched with the mounting plate of the vertical rib on the first template 1.

[0045] In the above scheme, the problem that the steel formwork is connected by bolts during assembly is solved, which increases the workload. The force applied by each bolt to the steel formwork is different, resulting in different connection strengths of the steel membrane plate fixing points 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. The number of mounting seats 9 varies according to the height of the first formwork 1. The diameter of the sliding rod 10 is smaller than the diameter of the through hole of the second formwork 2, while the length of the limiter 12 is larger than the diameter of the through hole of the second formwork 2. A metal sleeve is installed on the outer side of the fixing column 13 to reduce the gap between the fixing column 13 and the wedge frame 14. The friction force of the wedge frame 14 is vertically arranged, and the front and rear sides of the wedge frame 14 are both wedge plates. A spline groove is arranged on the outer side of the sliding rod 10, and a spline is arranged on the inner wall of the mounting seat 9. The mounting seat 9 is splined 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 a vertical upward 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 template 1. The second bolt 19 is arranged in the middle of the second sliding plate 17, and the second bolt 19 is perpendicular to the second sliding plate 17.

[0046] Specific workflow: The staff places the steel template on the left side of the first template 1. At this time, the first template 1 will contact the second template 2 of the left steel template. The first template 1 and the second template 2 described below are both in the above positional relationship. What is described here is the assembly process of the first template 1 and the left second template 2. The positional relationship will not be described below.

[0047] During the installation of the left 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 pouring cement. 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. Then the staff twists the second bolt 19 with a wrench (electric or manual), and the second bolt 19 uses the thread to pull the second sliding plate 17 to the right, and the second sliding plate 17 moves to the right along the first formwork 1. At the same time, the second sliding plate 17 moves to the right. Pull ten pull ropes 18 to the right, taking the pull rope 18 on the uppermost side as an example; the pull rope 18 moves to the right along the sliding rod 10, and 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 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 a 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 the torsion spring is tightened. As the second sliding plate 17 moves to the right, the pull rope 18 is also gradually stretched.

[0048] Then the staff uses a tool to rotate the first bolt 16, the first bolt 16 rotates and moves upward along the first template 1, the lower end of the first bolt 16 drives the first sliding plate 15 to move upward along the vertical ribs of the first template 1, and the first sliding plate 15 drives all the wedge frames 14 thereon to move upward, taking the uppermost wedge frame 14 as an example; the wedge frame 14 squeezes the fixing columns 13 on the mounting seat 9 and the sliding rod 10 upward, and the left and right adjacent fixing columns 13 are squeezed away from each other by the wedge frame 14, the elastic member between the mounting seat 9 and the sliding rod 10 is stretched, and the two fixing columns 13 on the right drive the sliding rod 10 to move rightward, and the sliding rod 10 drives the limit The member 12 moves until the limiting member 12 fits against the second template 2. During the movement of the limiting member 12 to the right, the pull rope 18 always maintains elastic force, thereby keeping the limiting member 12 in a vertical state. As the wedge frame 14 moves upward, the limiting member 12 applies an extrusion force to the right on the second template 2, thereby making the right side of the second template 2 fit tightly against the left side of the first template 1. Then the staff stops rotating the first bolt 16. Under the action of the thread, the first sliding plate 15 is located in this position, thereby ensuring the extrusion force of the limiting member 12 on the second template 2. The two steel templates are connected by rotating the first bolt 16, thereby improving the efficiency of steel template assembly.

[0049] When the steel formwork is to be dismantled and demoulded, the staff first rotates the second bolt 19 to move the second sliding plate 17 to the left and reset, and releases the tension of the pull rope 18 until the second sliding plate 17 is reset. Then the staff rotates the first bolt 16 in the opposite direction to move the wedge frame 14 downward, and under the action of the elastic member, the sliding rod 10 moves to the left and resets. In the above process, under the elastic force of the torsion spring, the limit member 12 gradually resets to a horizontal state, and then the two steel formworks are separated.

[0050] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
