Description

Technical Field

[0001] The present invention belongs to the technical field of building formwork, and particularly relates to a special-shaped formwork for concrete pouring. Background Art

[0002] During the building construction process, the shapes of buildings are various, such as arc-shaped and bent-shaped. When pouring these building structures, custom formwork is generally required. Currently, aluminum formwork is generally used. The custom formwork is disposable, and the cost of the custom formwork of aluminum formwork is relatively high. Moreover, after the custom design is completed, it takes time to cast, which prolongs the construction period.

[0003] In the prior art, the invention patent with the application publication number of CN109356377A discloses a freely combinable chain-type concrete formwork. The freely combinable chain-type concrete formwork includes a plurality of panel boards, and the panel boards are made of plastic-coated steel plates; cylindrical slots are provided at the four corners of the panel boards and are subjected to dip coating treatment after welding; through holes for reinforcement are reserved on the panel boards, and cylindrical steel pipes for fixing are inserted in the middle to combine the panel boards into a new integral panel board. Adjacent panel boards are connected to each other through U-shaped steel bars. Two U-shaped steel bars are used to connect every two panel boards, and the head and tail panel boards are connected to form a geometric body with a cavity, and concrete is poured into the cavity. Angle steel is installed at the fold joints of the panel boards. Although the panel boards of this freely combinable chain-type concrete formwork can rotate, it is fixed by using ordinary sleeves and inserting cylindrical steel pipes, and can only be used for pouring linear structures and cannot be used for pouring curved surface structures.

Detailed implementation mode

[0031] The present invention will be further described below in conjunction with the embodiments of the present invention and the accompanying drawings.

[0032] Embodiment 1

[0033] The special-shaped formwork for concrete pouring in this embodiment includes: a plurality of formwork main bodies 100, connecting components and reinforcement components.

[0034] The formwork main body is an aluminum formwork, and a plurality of backing ribs 110 for reinforcement are arranged on the formwork main body. Connecting seats 120 are arranged on the left and right sides of the formwork main body. A connecting hole 121 extending in the up and down direction is opened on the connecting seat 120. A reinforcement seat 130 is arranged on the formwork main body, and a reinforcement hole 131 is opened on the reinforcement seat 130.

[0035] The connecting component is used to connect a plurality of formwork main bodies, and includes a connecting shaft 200 inserted into the connecting hole 121 and a connecting plate 300 sleeved on two adjacent connecting shafts 200. The connecting plate 300 is provided with an internal anti-rotation member for preventing the connecting shaft 200 from rotating, and the connecting shaft 200 is provided with an external anti-rotation member corresponding to the internal anti-rotation member to prevent the connecting shaft 200 from rotating. A connecting shaft limiting member for limiting the relative rotation between the connecting shaft and the connecting seat is arranged on the connecting seat 120, and the connecting shaft limiting member is a connecting shaft limiting groove 122 opened on the connecting seat.

[0036] The connecting plate 300 is of a wasp-waist structure. The left and right parts of the connecting plate 300 are respectively provided with shaft holes 310 matching with two connecting shafts 200. The internal anti-rotation member is four anti-rotation grooves 320, and the anti-rotation grooves 320 extend along the axial direction of the shaft hole. The external anti-rotation member is an anti-rotation convex block 210 corresponding to the anti-rotation groove 320. The anti-rotation convex block 210 extends radially outward along the connecting shaft 200 so that the connecting shaft 200 stops rotating when the anti-rotation convex block 210 is located in the anti-rotation groove 320. The anti-rotation convex block 210 is an arc-shaped convex block for sliding up and down along the anti-rotation groove.

[0037] The anti-rotation groove 320 is formed by intervals of groove plates protruding axially from the inner wall of the shaft hole. The groove plates are located at the lower part of the shaft hole. The upper part above the groove plates in the shaft hole is an avoidance space for avoiding the anti-rotation protrusion so that the connecting shaft can rotate after moving upward axially.

[0038] There are four connecting seats 120 arranged in sequence from top to bottom. The connecting seats 120 extend in the up-and-down direction. There is a gap between the upper part of the upper connecting seat 120 and the upper end of the template main body 100, and there is a gap between the lower part of the lower connecting seat 120 and the lower end of the template main body. The connecting plate 300 is located between two adjacent connecting seats, and the two adjacent connecting seats block the connecting plate.

[0039] The upper end of the connecting shaft 200 is provided with a connecting shaft positioning handle 220. The connecting shaft positioning handle 220 cooperates with the connecting shaft limiting groove 122. When the connecting shaft positioning handle 220 is located in the connecting shaft limiting groove 122, the connecting shaft 200 and the template main body will not rotate relatively. When the connecting shaft positioning handle 220 disengages from the connecting shaft limiting groove 122, the connecting shaft 200 and the template main body 100 can rotate relatively. The upper part of the upper connecting seat 120 is provided with a connecting shaft positioning seat 123 for fixing the connecting shaft positioning handle at the upper part so that the anti-rotation protrusion disengages from the anti-rotation groove. The connecting shaft positioning seat 123 is provided with a connecting shaft positioning card slot 124 for clamping the connecting shaft positioning handle 220. The user pulls the connecting shaft 200 upward through the connecting shaft positioning handle, places the connecting shaft positioning handle 220 in the connecting shaft positioning card slot 124, so that the anti-rotation protrusion disengages from the anti-rotation groove. Because there is an avoidance space for avoiding the anti-rotation protrusion in the shaft hole, the connecting shaft and the connecting plate can rotate relatively. At this time, the adjacent template main bodies can rotate relatively, and the angle between the adjacent template main bodies can be adjusted. After adjusting to the appropriate position, the connecting shaft is lowered so that the anti-rotation protrusion is located in the anti-rotation groove. Under the action of gravity, the connecting shaft positioning handle at the upper end of the connecting shaft is clamped on the upper part of the connecting seat, preventing the connecting shaft from slipping off the connecting seat, and the anti-rotation protrusion is exactly located in the anti-rotation groove, and the connecting shaft and the connecting plate will not rotate relatively. The connecting shaft positioning handle of the connecting shaft is clamped between the adjacent two template main bodies and cannot rotate relatively, realizing locking. This kind of locking is rigid locking. After locking, the adjacent two template main bodies will not rotate, and there will be no problems of leakage or slurry explosion during pouring.

[0040] The lower end of the connecting shaft 200 is provided with a connecting shaft anti-disengagement convex ring 230 for preventing the connecting shaft from disengaging from the connecting seat.

[0041] Reinforcing components for reinforcing multiple formwork bodies, including multiple reinforcing bars 400 inserted through reinforcing holes and connecting components connecting adjacent reinforcing bars. The reinforcing bars 400 are square bars, and the reinforcing holes 131 are square holes matching the square bars. There is a gap for the reinforcing bars to move in the square holes to enable good cooperation between adjacent reinforcing bars. The connecting components include a left end plate 500 and a right end plate 600 fixed to the left and right ends of the reinforcing bars respectively. The left end plate is fixed to the upper part of the side of the reinforcing bar, and the right end plate is fixed to the lower part of the side of the reinforcing bar. The left end plate and the right end plate are arranged in an up-and-down cooperation. Rounded corners are provided on the left side of the left end plate and the right side of the right end plate to facilitate relative rotation.

[0042] The left end plate 500 is provided with an upper locking hole 510, and the right end plate 600 is provided with a lower locking hole 610 corresponding to the upper locking hole 510. An insertion pin 700 is inserted into the upper locking hole 510 and the lower locking hole 610, and a locking member for locking the rotation of adjacent two reinforcing bars is arranged between the insertion pin 700 and the lower locking hole. The locking member includes a locking block extending radially along the insertion pin 700 and a locking groove 611 formed on the inner wall of the lower locking hole. The aperture of the upper locking hole is larger than that of the lower locking hole so that when the insertion pin moves upward, the locking block disengages from the locking groove and adjacent two reinforcing bars can rotate relatively.

[0043] An insertion pin positioning handle 710 is arranged at the upper end of the insertion pin 700, and an insertion pin positioning seat 520 is arranged on the left end plate 500. The insertion pin positioning seat 520 is provided with an insertion pin positioning groove 521 for clamping the insertion pin positioning handle to disengage the locking block from the locking groove. An insertion pin limiting member for limiting the relative rotation between the insertion pin and the left end plate is arranged on the left end plate 500, and the insertion pin limiting member is an insertion pin limiting groove 530. An insertion pin anti-disengagement convex ring 720 for preventing the insertion pin from disengaging from the upper locking hole and the lower locking hole is arranged at the lower end of the insertion pin 700. Moving the insertion pin upward and placing the insertion pin positioning handle in the insertion pin positioning groove 521 can adjust the relative position of adjacent two reinforcing bars to make it match well with the formwork body. After adjustment, the insertion pin is lowered. Under the action of gravity, the insertion pin positioning handle is clamped on the left end plate to prevent the insertion pin from disengaging from the upper locking hole and the lower locking hole, and the locking block is located in the locking groove to achieve locking. By respectively pulling and fixing the formwork bodies at both ends with the opposite formwork bodies, the fixation of the formwork can be realized.
