Description

Technical Field

[0001] The present application relates to the technical field of water ditch cable trolley equipment, and in particular to a demoulding device for a water ditch template. Background Art

[0002] In tunnel engineering, in order to meet the drainage needs of the tunnel, water trenches are usually set on both sides of the tunnel. The water trenches extend in the extension direction of the tunnel and are particularly long. During the construction of the water trenches, the formwork is usually lifted upward to demould. If the length of the unit formwork is too long, the straightness of the water trench after forming and the internal space size accuracy are high, and the adhesion between the concrete and the formwork after the lining is completed is large, which may easily cause the concrete to fall off during demoulding and damage the formed surface. However, dividing the water trench formwork into multiple shorter sections for separate construction may reduce the demoulding difficulty to a certain extent, but will lead to an increase in construction steps and slow construction progress.

[0036] Example

[0037] The tunnel water ditch structure usually includes a left ditch and a right ditch that are parallel to each other, and a cable trough is provided between the left ditch and the right ditch. Figure 1As shown, it includes a left ditch formwork 1, a right ditch formwork 2 and a bidirectional demoulding cylinder 3. The left ditch formwork 1 includes a first side formwork 11 and a second side formwork 12 that are relatively arranged, and the right ditch formwork 2 includes a third side formwork 21 and a fourth side formwork 22. When the concrete lining is completed, the first side formwork 11 and the second side formwork 12 are respectively attached to the inner walls on both sides of the left ditch, and the third side formwork 21 and the fourth side formwork 22 are respectively attached to the side walls on both sides of the right ditch. Specifically, the first side formwork 11, the second side formwork 12, the third side formwork 21 and the fourth side formwork 22 are arranged in sequence along the lateral direction of the ditch. Refer to Figure 3 As shown, the bidirectional demoulding oil cylinder 3 includes a cylinder body 31 and a first piston rod 32 and a second piston rod 33 respectively connected to both ends of the cylinder body 31; the bidirectional demoulding oil cylinder 3 is arranged along the transverse direction of the water ditch, that is, the first piston rod 32 and the second piston rod 33 can move along the transverse direction of the water ditch when in action, and the movement directions of the first piston rod 32 and the second piston rod 33 are opposite. The first piston rod 32 is connected to the first side mold 11 and the third side mold 21 to drive the first side mold 11 and the third side mold 21 to move in the same direction; the second piston rod 33 is connected to the second side mold 12 and the fourth side mold 22 to drive the second side mold 12 and the fourth side mold 22 to move in the same direction.

[0038] Before demoulding, the bidirectional demoulding cylinder 3 is used to drive the side forms in the left and right ditch formworks 2 to move away from the inner wall of the concrete, that is, the first side form 11 and the third side form 21 are driven to move toward the right, and the second side form 12 and the fourth side form 22 are driven to move toward the left, so that the side forms are separated from the inner wall of the concrete after lining, and then the demoulding device is lifted as a whole.

[0039] The demoulding device of a ditch formwork provided in the present embodiment drives the side forms of the ditch formwork on both sides to move toward the middle thereof simultaneously through the bidirectional demoulding cylinder 3, thereby simultaneously separating each side formwork from the corresponding concrete side wall, avoiding damage to the concrete surface after lining is completed when lifting the ditch formwork, thereby increasing the length of the unit formwork without damaging the concrete surface, improving the quality and aesthetics of the ditch, and also improving the construction efficiency.

[0040] Specifically, continue to refer to Figures 1 to 3As shown, the end of the first piston rod is connected to a first slide 4, to which a first horizontal tie rod 6 is connected, which extends in the transverse direction of the ditch and is connected to the third side mold 21; the end of the second piston rod 33 is connected to a second slide 5, to which a second horizontal tie rod 7 is connected, which extends in the transverse direction of the ditch and is connected to the second side mold 12. A first connecting ear 41 is provided below the first slide 4, and the first connecting ear 41 is connected to the first mold; a second connecting ear 51 is provided below the second slide 5, and the second connecting ear 51 is connected to the second mold. Thus, when the first piston rod 32 moves, it drives the first side mold 11 and the third side mold 21 to move in the same direction, and when the second piston rod 33 moves, it drives the second side mold 12 and the fourth side mold 22 to move in the same direction.

[0041] Specifically, refer to Figure 4 As shown, the first slide 4 includes a first seat body 42 and a first end plate 43 connected to the end of the first seat body 42, and the first end plate 43 extends along the outer side of the seat body and is connected to the first horizontal tie rod 6. A sleeve 8 is also sleeved on the outer side of the two-way demoulding cylinder 3, so that the first horizontal tie rod 6 is located outside the sleeve 8; and the first slide 4 and the second slide 5 extend out of the sleeve 8 respectively and slide with the sleeve 8. On the one hand, it plays a guiding role in the moving direction of the slide, and on the other hand, the sleeve 8 is connected to the cable trough template 9, and the cable trough template 9 is located between the left ditch template 1 and the right ditch template 2, so that the ditch template and the cable trough template 9 form a whole, so that the ditch cable trough template 9 can be moved upward as a whole to demould the ditch cable trough template 9.

[0042] Specifically, a lifting hinge ear 81 is provided above the sliding sleeve 8. During demoulding, the trolley is connected to the sliding sleeve 8 through the hinge ear, thereby lifting the template to realize demoulding.

[0043] Specifically, the left gutter template 1 also includes a bottom plate 13, and the bottom plate 13 is connected to the first side mold 11 and the second mold, respectively, and a deformation portion 15 is formed at the connection between the bottom plate 13 and the first side mold 11 or the second side mold 12, so that when the first side mold 11 or the second side mold 12 moves, the deformation portion 15 is bent and deformed. The right gutter template 2 also includes a corresponding bottom plate 13 and a profile 14 structure. The left gutter template 1 and the right gutter template 2 are both steel templates. When the two-way demolding cylinder 3 contracts and drives each side mold to move, a bending deformation can occur between the side mold and the bottom plate 13. The bending deformation is extremely small, and it is only necessary to separate the side mold from the inner wall of the gutter. It is an elastic deformation. When the two-way demolding cylinder 3 is extended, the deformation portion 15 can be restored to its original state.

[0044] Specifically, the bottom plate 13 is connected with a profile 14 extending in the longitudinal direction of the ditch. The bottom plate 13 is reinforced by the profile 14. Since the length of the unit template is long, reaching tens of meters, reinforcing the bottom plate 13 with the profile 14 can prevent the bottom plate 13 from bending in the longitudinal direction.

[0045] Demolding process: the bidirectional demoulding cylinder 3 is contracted, the first slide 4 drives the first side form 11 and the third side form 21 to move toward the right, the second slide 5 drives the second side form 12 and the fourth side form 22 to move toward the left, and the deformation part 15 is bent, so that the lateral dimensions of the left ditch form 1 and the right ditch form 2 are reduced, and the side forms are separated from the inner wall of the concrete; then the ditch form cable trough form 9 is lifted as a whole.

[0046] The mold erection process is opposite to the demoulding process and will not be described in detail.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
