Description

Technical Field

[0001] The invention relates to the field of building construction template tools, in particular to an adjustable arc column template device. Background Art

[0002] Civil engineering, also known as civil engineering, is a general term for civil engineering and construction engineering. It is an engineering project that builds various facilities and places for human life, production, protection and other activities. It includes various technical activities such as surveying, design and construction during the construction process. Civil engineering construction requires the use of cement and steel frame casting to manufacture bridges and beams. Cement casting requires the use of shaping plates to stabilize the cement casting and make the cement casting more stable.

[0003] The standard plates used in civil construction on the market have the following disadvantages: standard plates with different curvatures are needed to manufacture bridges and beams in civil construction. The angles of existing standard plates cannot be adjusted, so standard plates with different curvatures need to be purchased in civil construction, which requires a huge cost. Secondly, the connection angles between the standard plates cannot fit together, which makes it easy for the casting to flow out at the connection position, which easily causes the casting of bridges and beams to fail. Summary of the Invention

[0004] The invention discloses an adjustable arc column formwork device.

[0005] The technical problem to be solved is: the curved surface parts of curved columns of different specifications need to be customized with templates. During bridge construction, there are a large number of curved columns of various specifications, and a variety of different curved templates need to be customized.

[0006] In order to solve the above technical problems, the present invention provides an adjustable arc column formwork device, which adopts the following solution.

[0007] Adjustable curved column formwork device, middle connecting formwork device and curved formwork devices at both ends;

[0008] The arc template device includes a first base, a first vertically arranged rotating shaft is installed on the first base, one side of the two arc templates is rotated and set on the rotating shaft, a support base is set on the outer side of the first rotating shaft, and a driving mechanism on the support base is used to drive the two arc templates to rotate.

[0009] The driving mechanism includes a connecting rod installed at the output end of the electric push rod, the other end of the connecting rod is hingedly connected to the arc template; both arc templates are connected to the electric push rod through the connecting rod;

[0010] The connecting template device includes a second base, the second base is fixedly mounted with a vertical connecting template, and the side of the connecting template is in close contact with the side of the arc template away from the first rotating shaft.

[0011] Preferably, the left and right arc-shaped template devices are connected to each other through two sets of connecting template devices arranged in the front and rear, and the arc template of the arc-shaped template device and the connecting template of the connecting template device together form a closed ring; each set of connecting template devices includes several, and the front and rear sets of connecting template devices have the same length after being spliced together.

[0012] Preferably, the second bases of adjacent splicing template devices are detachably fixed to each other to avoid misalignment of the connecting templates;

[0013] The first template and the second template are capable of relative movement.

[0014] Preferably, the side edges of the connecting template are in close contact with the arc-shaped template via a rotating plate, and the rotating plate is rotatably mounted on the left and right side edges of the connecting template.

[0015] Preferably, an adjustment structure is provided between the rotating plate and the connecting template for adjusting the angle of the rotating plate so that it is aligned with the arc template and fits the side of the arc template;

[0016] The adjustment structure includes a first adjustment rod with one end hingedly connected to the rotating plate, a second adjustment rod with one end hingedly connected to the connecting template, an adjustment sleeve is arranged between the first adjustment rod and the adjustment rod, and the two ends of the adjustment sleeve are respectively threadedly connected to the first adjustment rod and the second adjustment rod, and the threads at the two ends of the adjustment sleeve are rotated in opposite directions.

[0017] Preferably, a spring is further provided between the rotating plate and the connecting template, and the spring is a compression spring.

[0018] Preferably, the arc template device also includes a control panel, which is electrically connected to a sensor, and the sensor senses the position or rotation angle of the arc template; the control panel is connected to and controls the movement of the electric push rod.

[0019] Compared with the prior art, the adjustable curved column formwork device of the present invention has the following beneficial effects:

[0020] 1. When the curvature of the forming plate needs to be adjusted during the civil construction process, the operator sets the adjusted curvature through the control panel, and the control panel controls the electric push rod to open through the control sensor, and the output end of the electric push rod contracts, and the output end of the electric push rod drives the connecting frame to move, and the connecting frame drives the first limit ring to move, and the first limit ring drives the arc plate to rotate around the first rotating shaft, so that the angle of the arc plate is adjusted to the curvature required by the operator and stops. The curvature of the arc plate can be adjusted, so that there is no need to equip multiple sets of forming plates with different curvatures during civil construction, which reduces the use cost. At the same time, controlling the electric push rod through the control panel improves the efficiency of adjusting the curvature of the forming plate and improves the accuracy of the curvature adjustment.

[0021] 2. When the connecting plate needs to fit with curved plates of different curvatures, the operator moves one side of the rotating plate to one side of the curved plate, and the spring reset pushes the rotating plate to rotate through the second rotating shaft. The spring pushes the rotating plate to fit with one side of the curved plate, so that the angles of the rotating plate and one side of the curved plate are matched with each other. The operator inserts a set of threaded connecting tubes into the outer wall of one end of the two sets of threaded racks, and the operator rotates the threaded connecting tube forward. The forward rotation of the threaded connecting tube drives one end of the two sets of threaded racks to move toward the inside of the threaded connecting tube. The threaded connecting tube, the threaded rack and the second limiting ring limit the connecting plate and the rotating plate, and fix the angle between the connecting plate and the rotating plate, so that the rotating plate cannot be rotated by the second rotating shaft, so that the angle of the rotating plate and the curved plate is fit, thereby improving the applicable range of the connecting plate and the rotating plate, reducing the probability of cast concrete flowing out in the fixed plate, and improving the stability between the curved plate and the rotating plate in the fixed plate.

[0035] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0036] In the present invention, unless otherwise stated, directional words such as "up, down, left, right" generally refer to the directions in the attached drawings. Figure 1 The upper, lower, left and right shown in the figure are referred to as the inner and outer relative to the outline of each component. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] In order to solve the problem that the curved surface of the curved columns of different specifications need to be customized with templates, there are a large number of curved columns of different specifications in bridge construction, and a variety of different curved templates need to be customized, the present invention proposes an adjustable curved column template device

[0038] Adjustable curved column formwork device, characterized by a connecting formwork 7 device in the middle and curved formwork 5 devices at both ends;

[0039] The curved template 5 device includes a first base 1, a vertically arranged first rotating shaft 4 is installed on the first base 1, one side of the two curved templates 5 is rotated and set on the rotating shaft, a support base 2 is set on the outer side of the first rotating shaft 4, and a driving mechanism on the support base 2 is used to drive the two curved templates 5 to rotate.

[0040] The driving mechanism includes a connecting rod 301 installed at the output end of the electric push rod 3, and the other end of the connecting rod 301 is hingedly connected to the arc template 5; both arc templates 5 are connected to the electric push rod 3 through the connecting rod 301;

[0041] The connecting template 7 device includes a second base 6 , and the second base 6 is fixed with the vertical connecting template 7 , and the side of the connecting template 7 is in close contact with the side of the arc template 5 away from the first rotating shaft 4 .

[0042] like Figure 2 As shown in the figure, the curved template 5 of the present invention will disrupt the arc of the entire curved surface to a certain extent after adjustment. Therefore, the adjustment angle of the curved template 5 cannot be too large, generally not exceeding 20°. Preferably, the adjustment angle of any curved template 5 does not exceed ±5° of the reference position. The so-called reference position is the position where the two curved templates 5 form a smooth curved surface.

[0043] However, in actual bridge construction, especially in overpasses with multiple main roads, branch roads, and ramps, the bridge's piers and columns often come in a variety of sizes. However, the sizes of these columns generally don't differ significantly. In other words, in actual use, if the curved template 5 can be slightly adjusted and deformed, it can accommodate the construction of multiple piers and columns of varying sizes within a single construction site. Furthermore, the resulting deformation of the curved template 5 will not affect the strength of the piers and columns, remaining within the permitted construction tolerances for the columns.

[0044] One curved template 5 can be driven by an independent driving mechanism. However, when the two curved templates 5 need to move, they are adjusted in the same direction, that is, the rotation directions of the two curved templates 5 are opposite. Therefore, it is preferred to use the same driving mechanism to drive the two curved templates 5 on the curved template 5 device at the same time. Specifically, Figure 2 As shown in , two connecting rods 301 are hinged on the electric push rod 3 at the same time, and the two connecting rods 301 are respectively connected to the two arc-shaped templates 5.

[0045] like Figure 2 and Figure 4 As shown in FIG, the left and right curved templates 5 are connected to each other by two sets of connecting templates 7 arranged in front and behind. The curved templates 5 of the curved template 5 and the connecting templates 7 of the connecting template 7 together form a closed ring. Each set of connecting templates 7 includes several connecting templates, and the front and rear sets of connecting templates 7 have the same length after being spliced together. The ring enclosed by the curved templates 5 and connecting templates 7 is hollow, without a base or other structure inside, to facilitate subsequent demolding and removal.

[0046] like Figure 4 As shown in , during the pouring operation, the concrete will exert outward stress on the connecting template 7. In order to prevent the connecting template 7 from being dislocated, the second bases 6 of the adjacent splicing template devices are detachably fixed to each other to prevent the connecting template 7 from being dislocated.

[0047] However, after the position of the arc template 5 is adjusted, since the side of the connecting template 7 needs to fit the side of the arc template 5, the position of the connecting template 7 also needs to be adjusted. Figure 4 Therefore, the first template and the second template can move relative to each other. When the position of the connecting template 7 is adjusted, all the connecting templates 7 in a group move synchronously.

[0048] like Figure 2 As shown, after the arc template 5 is adjusted, its angle will also change accordingly, but the connecting template 7 needs to remain in a horizontal state, so the side of the connecting template 7 is tightly attached to the arc template 5 through the rotating plate 8, and the rotating plate 8 is rotatably installed on the left and right sides of the connecting template 7.

[0049] like Figure 3 An adjustment structure is provided between the rotating plate 8 and the connecting template 7 for adjusting the angle of the rotating plate 8 so that it is aligned with the arc template 5 and fits with the side of the arc template 5; the adjustment structure includes a first adjustment rod 802 hingedly connected to the rotating plate 8 at one end, and a second adjustment rod 803 hingedly connected to the connecting template 7 at one end, and an adjustment sleeve 804 is provided between the first adjustment rod 802 and the adjustment rod, and the two ends of the adjustment sleeve 804 are threadedly connected to the first adjustment rod 802 and the second adjustment rod 803 respectively, and the threads at the two ends of the adjustment sleeve 804 are screwed in opposite directions.

[0050] A spring 805 is further provided between the rotating plate 8 and the connecting template 7 , and the spring 805 is a compression spring.

[0051] Specifically, when the connecting template 7 is connected to the adjacent side of the curved surface template, the connecting template 7 needs to be adjusted to a suitable angle and fixed to adapt to the edge of the curved surface template 5. Therefore, on the side where the connecting template 7 and the curved surface template are connected, an adjustment structure is used to adjust the angle of the rotating plate 8 and fix the rotating plate 8. At this time, the spring 805 is in an invalid state and does not play a substantial role. Figure 4 When the connecting templates 7 and 7 are adjacent, since the second bases 6 are fixed to each other and the two adjacent connecting templates 7 are arranged in parallel, the adjustment sleeve 804 can be removed and the elastic force of the spring 805 can be used to press the two rotating plates 8 together. At this time, the adjustment structure is in a failed state and the spring 805 takes effect.

[0052] The arc template 5 device also includes a control panel, which is electrically connected to a sensor that senses the position or rotation angle of the arc template 5 ; the control panel is connected to and controls the movement of the electric push rod 3 .

[0053] Example:

[0054] See also Figure 1-4 The present invention provides a technical solution: a shaped plate with intelligently adjustable curvature for civil construction, comprising a first base 1, a support base 2, an electric push rod 3, a first rotating shaft 4, an arc template 5, a second base 6, a connecting template 7 and a rotating plate 8. A support base 2 is provided on one side of the first base 1, and an electric push rod 3 is installed on one side of the support base 2. Two groups of first rotating shafts 4 are provided at the top of the first base 1, and two groups of arc templates 5 are sleeved on the outer wall of one group of the first rotating shafts 4. A second base 6 is provided on the side of the first base 1 away from the support base 2, a connecting template 7 is provided on the top of the second base 6, and a rotating plate 8 is provided on one side of the connecting template 7.

[0055] The support base 2 includes a control panel 201 . The control panel 201 is installed on one side of the support base 2 . A control sensor is installed inside the support base 2 . The control sensor is connected to the electric push rod 3 .

[0056] The electric push rod 3 includes a connecting rod 301 , and the connecting rod 301 is sleeved on the outer wall of the output end of the electric push rod 3 .

[0057] The arc-shaped template 5 includes a first limiting ring 501 . The outer wall of the arc-shaped template 5 is provided with the first limiting ring 501 which is sleeved on the outer wall of one end of the connecting rod 301 .

[0058] In specific implementation, when the curvature of the forming plate needs to be adjusted during the civil construction process, the operator sets the adjusted curvature through the control panel 201, and the control panel 201 controls the electric push rod 3 to open through the control sensor, and the output end of the electric push rod 3 contracts, and the output end of the electric push rod 3 drives the connecting rod 301 to move, and the connecting rod 301 drives the first limiting ring 501 to move, and the first limiting ring 501 drives the arc template 5 to rotate around the first rotating shaft 4, so that the angle of the arc template 5 is adjusted to the curvature required by the operator and stops. The curvature of the arc template 5 can be adjusted, so that there is no need to equip multiple sets of forming plates with different curvatures during civil construction, which reduces the cost of use. At the same time, the control panel 201 controls the electric push rod 3 to improve the efficiency of adjusting the curvature of the forming plate, and at the same time improves the accuracy of the curvature adjustment.

[0059] The rotating plate 8 includes a second rotating shaft 801, a first adjusting rod 802, a second adjusting rod 803, an adjusting sleeve 804, and a spring 805. The second rotating shaft 801 is provided on one side of the rotating plate 8. The connecting template 7 and the rotating plate 8 are rotatably connected via the second rotating shaft 801. Eight sets of first adjusting rods 802 are provided on one side of each of the connecting template 7 and the rotating plate 8. The inner wall of each of the first adjusting rods 802 is sleeved with a second adjusting rod 803 that passes through the first adjusting rod 802. The outer walls of the two ends of the second adjusting rod 803 are provided with opposite threads. The outer walls of the two sets of second adjusting rods 803 are sleeved with an adjusting sleeve 804 on one end. The adjusting sleeve 804 is threadedly connected to the second adjusting rod 803. A spring 805 connected to the rotating plate 8 is provided on one side of the connecting template 7.

[0060] When the cam 802 is in the process of being rotated, the operator can adjust the angle of the cam 802 and the cam 803 so that the cam 802 and the cam 803 are aligned.

[0061] When the connecting template 7 needs to be fitted with the connecting template 7, the spring 805 resets and pushes the rotating plate 8 to rotate through the second rotating shaft 801, and the spring 805 pushes the rotating plate 8 to fit with one side of the arc template 5.

[0062] To sum up: when casting and manufacturing bridges or beams and columns during civil construction, the operator splices the curved formwork 5 with the connecting formwork 7, fits one side of the rotating plate 8 with one side of the curved formwork 5, and the operator places the steel frame into the shaping plate. The operator pours cement on the inner side of the shaping plate to bond the cement to the steel frame. The shaping plate shapes the cement and the steel frame, and bridges and beams and columns are manufactured by pouring cement and steel frame. The shaping plate facilitates the shaping of bridges and beams and columns.

[0063] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention.
