Description

Technical Field

[0001] The utility model belongs to the technical field of construction templates, and in particular relates to a secondary structural column casting template. Background Art

[0002] The Chinese patent application number 202010976045.8 discloses a secondary structural column formwork, which specifically discloses that "after pouring is completed, the limit rod 5 is twisted to move the limit rod 5 in the direction away from the front formwork 2, and then the end of the guide plate 42 close to the front formwork 2 is pushed to slide vertically upward, so that the end of the guide plate 42 away from the front formwork 2 slides horizontally in the direction away from the front formwork 2. At this time, the end of the guide plate 42 close to the front formwork 2 will scrape off the funnel 4-shaped concrete block protruding outward from the funnel 4, thereby repairing and leveling the concrete poured at the funnel 4."

[0003] Obviously, the above structure has the defect that, during operation, it is necessary not only to twist the two limit rods, but also to push the guide plate to scrape the inner side upward to remove the excess concrete. The operation is troublesome and the concrete scraped by the guide plate will be deformed under the action of gravity due to the lack of lateral external force support, which affects the surface appearance after curing.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 8 As shown, a secondary structural column casting template is used to cast concrete between two spaced walls 100 to form a structural column 200. The template includes a front template 1, a rear template 2 and a diversion and mold mechanism 3. The front template 1 and the rear template 2 are respectively fixed to the front side and the rear side of the wall. A casting port is provided in the center of the front template 1, and the width of the casting port does not exceed the width of the structural column.

[0028] The flow guide and mold clamping mechanism 3 includes a gate side plate 4, a flow guide 5, a stopper 6 and a mold clamp 7. The gate side plate 4 is symmetrically mounted on the front template 1 on both sides of the pouring port through a fixing plate 401 and bolts. The gate side plate 4 and the fixing plate 401 are also reinforced by equilateral angle steel to prevent lateral bending. The inner side surface of the gate side plate 4 is perpendicular to the front template 1 and is flush with the side edge of the pouring port.

[0029] The deflector 5 is rotatably installed at the lower edge of the pouring port through the hinge 9, and the side surfaces of the deflector 5 form a sliding contact with the gate side plate 4 on the corresponding side. As a preferred example, the deflector 5 includes a base plate 502, a deflector 501 installed on the inner side of the base plate 502, and a sealing side plate 503 vertically installed on both sides of the base plate 502. The base plate 502 and the sealing side plate 503 are reinforced by equilateral angle steels to prevent lateral bending. The size of the base plate 502 is the same as that of the pouring port, so that the pouring port can be completely blocked after mold closing and the inner side surface of the deflector 501 is coplanar with the inner side surface of the front template 1 to ensure the surface flatness of the structural column. The sealing side plate 503 forms a sliding contact with the gate side plate 4 on the same side.

[0030] As a preferred example, the sealing side plate 503 and the gate side plate 4 are both fan-shaped plates with the same structure, and the corresponding central angle is 60°.

[0031] The stopper 6 is installed on the guide 5 to control the mold closing angle of the guide 5. As a preferred example, the stopper 6 is installed at the rear edge of the sealing side plate 503. The stopper 6 is a block structure. After the mold is closed, the stopper 6 contacts the rear edge of the gate side plate 4 to prevent the guide 5 from rotating further. At this time, the guide 5 is in the mold closing state.

[0032] The mold clamp 7 is installed on the gate side plate 4 to control the rotation angle of the deflector 5.

[0033] As a preferred example, the mold clamp 7 includes a bracket 701, a gear 702, an arc rack 704, a worm 705, a worm wheel 706 and a driving rod 708. The fixed ends on both sides of the bracket 701 are fixedly mounted on the positions near the rear edge of the two gate side plates 4. A rotating shaft 703 is rotatably mounted on the bracket 701 through a bearing, and two gears 702 are symmetrically mounted on the rotating shaft 703. An arc rack 704 is mounted on each sealing side plate 503, and the arc rack 704 is meshed with the gear 702 on the same side one by one. The worm wheel 706 is mounted on the center of the rotating shaft 703, and the worm 705 is rotatably mounted on the bracket 701 through a bearing and meshes with the worm wheel 706, and its end is connected to the driving rod 708.

[0034] As a preferred example, an anti-deviation seat 707 is also installed at the bottom of the bracket 701, and an opening is set in the center of the anti-deviation seat 707 for the other end of the worm 705 to pass through and connect to the drive rod 708. In this way, the shaft of the worm 705 can be prevented from bending and affecting its connection with the worm wheel 706.

[0035] Since the pouring port is at a great height from the ground, in order to facilitate the ground personnel to better operate the driving rod 708 to smoothly close the mold, as a preferred example, the mold clamp 7 also includes a universal joint 709, which is connected between the worm 705 and the driving rod 708. The angle of the driving rod 708 can be adjusted through the universal joint 709, so as to make it more convenient for personnel to operate.

[0036] Since the deflector 5 is hingedly installed, a certain angle is formed between the deflector 501 and the front template 1 during the diversion, so an arc-shaped gap is formed between the lower edge of the deflector 501 and the lower edge of the pouring port. When pouring concrete to this height, the concrete will enter the gap, making it impossible for the deflector 5 to be molded. To solve this problem, as a preferred example, the template also includes an anti-blocking plate 8, the upper half of which is fixed to the lower edge of the deflector 501 by self-tapping screws, and the lower half is attached to the inner side of the front template 1. Obviously, the width of the anti-blocking plate 8 is the same as the width of the pouring port. The thickness of the anti-blocking plate 8 is 0.5mm-1mm. After the mold is opened, the anti-blocking plate 8 blocks the gap to prevent concrete from entering, and the anti-blocking plate 8 can move down along the edge after the mold is closed.

[0037] As a preferred example, the anti-blocking plate 8 is a thin metal plate with an initial deformation state. That is, the initial state of the anti-blocking plate 8 is a bending deformation with a certain angle, and the bending angle is exactly the angle between the guide plate 501 and the front template 1 after the mold is opened, for example, 45°. The lower edge of the anti-blocking plate 8 will be close to the inner side of the front template 1. As the concrete is poured, the anti-blocking plate 8 will be pressed against the inner side of the front template 1 by the concrete, but due to its thin thickness, the resistance of the lower edge moving downward when the mold is closed is small, thus becoming a straight plate.

[0038] like Figure 5 As shown, before pouring, the template is installed on two walls, and then the driving rod 708 is manually operated to open the deflector 5 to a suitable angle. Then the concrete is poured downward from the top of the deflector 5, and the concrete flows into the cavity between the walls under the guidance of the deflector 501. After the pouring is completed, the driving rod 708 is operated again to adjust the deflector 5 to the mold-closed state, and after a period of time (that is, the concrete has a certain hardness, so that it will not collapse and deform after losing the side support of the deflector 501), the template can be removed. The surface of the structural column obtained in this way is relatively flat, without obvious protrusions or depressions.
