Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a leak-proof precast building exterior wall panel formwork. Background Art

[0002] A building formwork is a temporary support structure, which is made according to the design requirements to form concrete structures and components in accordance with the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the building formwork and the external loads acting thereon. The purpose of formwork engineering is to ensure the quality of concrete works, construction safety, speed up the construction progress and reduce the project cost.

[0003] A building formwork mainly consists of three parts: a panel, a support structure and connectors. Among them, the panel plays the role of carrying the contents (such as concrete, etc.), and the connectors play the role of connecting the panels. For common planar building formworks, most of them are used for planar concrete supports, but it is inevitable that the panels need to be used at the corners (such as right-angle turns). For the panels on the plane, the connection area between the panels is large and the connection is relatively tight, so its sealing performance is guaranteed. However, for large corners, the connection between the panels changes from surface-to-surface to line-to-line, resulting in poor sealing performance at this place. During the concrete pouring and vibrating process, it is very easy for the concrete to leak or overflow, thereby polluting other parts and affecting the construction quality. Therefore, it is necessary to design a panel connection device that is more suitable for large angles. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a leak-proof precast building exterior wall panel formwork, which can well improve the sealing performance of the formwork at the corners.

As shown in the attached Figure 1 - attached Figure 6 As shown, the leak-proof precast building exterior wall panel formwork of this embodiment includes a pair of support plates 10 with side edges approaching each other, a blocking strip 21 provided between the joints of the pair of support plates 10, a pair of connecting strips 22 provided on the blocking strip 21, and a connecting component for connecting the connecting strip 22 and the support plate 10; one connecting strip 22 is arranged close to the side edge of one support plate 10; the blocking strip 21 abuts against the side edges of the pair of support plates 10 at the same time. Specifically, when in use, first lean the support plates 10 against each other and roughly determine the position, then snap the blocking strip 21 into the gap between the pair of support plates 10, and improve the contact area and the sealing effect by connecting the blocking strip 21 with the side edges of the pair of support plates 10 at the same time. Then use the connecting component to connect the support plates 10 with the blocking strip 21 and the connecting strips 22. In this way, the blocking strip 21 can not only well seal the gap between the pair of support plates 10 to prevent the leakage of liquid during pouring or perfusion, but also fix the pair of support plates 10 through the connecting strips 22 and the connecting component. In this way, for the support plates 10 at large corners or large bends, it can play a very good role in sealing and connecting.

[0028] The cross-section of the part of the blocking strip 21 in this embodiment close to the side edge of the support plate 10 is arc-shaped. Specifically, the arc-shaped blocking strip 21 contacts the side edge of the support plate 10, which can well improve the contact area and the sealing effect.

[0029] The connection component in this embodiment includes a first through hole 23 formed in the connection bar 22, a connection plate 24 disposed in the first through hole 23, a limiting rod 25 disposed at one end of the connection plate 24 away from the support plate 10, a second through hole 27 formed in the connection plate 24, a connection hole formed in the outer side wall of the support plate 10 on the side where they are close to each other, and a bolt 26 that passes through the second through hole 27 and is threadedly connected to the connection hole; the length of the limiting rod 25 is greater than the length of the first through hole 23. Specifically, the width of the first through hole 23 is greater than the width of the connection plate 24, so that the position and angle of the connection plate 24 can be adjusted according to the included angle of the support plate 10 and the thickness of the support plate 10, enabling it to fit well on the support plate 10.

[0030] In this embodiment, along the length direction of the connection bar 22, a plurality of connection components are provided. Specifically, the plurality of connection components can better improve the connection stability of the support plate 10.

[0031] A gap is provided between a pair of support plates 10 in this embodiment; it further includes a V-shaped sealing strip 28 disposed on the inner wall of the connection part of the pair of support plates 10, and the sealing strip 28 is detachably connected to the blocking strip 21; the sealing strip 28 is simultaneously in contact with the wall surfaces of the pair of support plates 10. A screw rod 29 is fixedly provided on one side of the sealing strip 28 close to the blocking strip 21, and the screw rod 29 passes through the blocking strip 21 and is threadedly connected to a nut 210; the nut 210 is in contact with the blocking strip 21. Along the length direction of the blocking strip 21, a plurality of screw rods 29 are provided, and a nut 210 is connected to each of the plurality of screw rods 29. Specifically, a V-shaped sealing strip 28 is provided on the inner wall of the support plate 10. By the sealing strip 28 fitting on the support plate 10, the sealing effect of the support plate 10 can be better improved, and the sealing strength and connection strength between the sealing strip 28, the blocking strip 21 and the support plate 10 can also be improved through the connection between the sealing strip 28 and the blocking strip 21. After the position of the connection plate 24 is fixed, the sealing strip 28 can be fixed on the inner wall of the support plate 10 by tightening the nut 210, and the angle of the sealing strip 28 needs to be made according to the specific angle of the support plate 10 or the angle of the existing sealing strip 28 is adjusted on site.

[0032] In summary, for the leak-proof prefabricated building exterior wall panel formwork of this embodiment, during use, first place the support plates 10 close together and roughly determine their positions, then snap the sealing strips 21 into the gaps between a pair of support plates 10. By connecting the sealing strips 21 to the sides of a pair of support plates 10 simultaneously, the contact area is increased, improving the sealing effect. Then use the connecting components to connect the support plates 10 to the sealing strips 21 and the connecting strips 22. In this way, the sealing strips 21 can not only seal the gaps between a pair of support plates 10 well to prevent liquid leakage during pouring or perfusion, but also fix a pair of support plates 10 through the connecting strips 22 and the connecting components. Thus, for the support plates 10 at large corners or large bends, it can play a very good role in sealing and connecting.
