Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a template for concrete pouring. Background Art

[0002] Concrete pouring refers to the construction process of pouring mixed concrete into a warehouse, leveling the warehouse, and compacting it. During the concrete pouring process, casting forms are required to provide space and shape for the concrete to be formed, ensuring that the concrete is poured into the corresponding shape and size according to the design requirements. The structure of the concrete pouring formwork mainly consists of three parts: a face plate, a support structure, and connectors. The face plate is the load-bearing plate that directly contacts the newly poured concrete. The support structure is a temporary structure that supports the face plate, concrete, and construction loads, ensuring that the building formwork structure is firmly combined and prevents deformation and damage. The connector is the accessory that connects the face plate and the support structure into a whole. In the prior art, to facilitate the transportation of the formwork, the formwork panels are often installed by splicing during use. At the same time, to prevent the concrete slurry from leaking from the panel joints, sealing components such as gaskets are often installed at the panel joints to seal the panel joints. However, the concrete slurry is in a fluid state before solidification, and the pressure at the bottom of the concrete slurry is relatively high, which exerts a large force on the sealing components, which can easily cause the concrete slurry to leak. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a template for concrete pouring. The sealing component of the template can automatically adapt to the high-pressure environment at the bottom of the concrete mud. The greater the pressure of the concrete mud, the stronger the sealing effect, which prevents the concrete mud from leaking from the connection of the template, improves the quality of concrete pouring, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a formwork for concrete pouring, comprising a pouring panel and a sealing mechanism;

[0005] Casting panels: There are four of them and they are perpendicular to each other. The surfaces of the casting panels are all provided with connecting frames, and the surfaces of the connecting frames are all installed with support columns;

[0006] Sealing mechanism: It includes a sealing pad, an extrusion plate and a top plate. The sealing pads are respectively located between two adjacent casting panels. The number of sealing pads between two adjacent casting panels is two and they form a group. The two sealing pads in the same group are slidingly connected with the extrusion plate and the top plate. The inclined surface of the extrusion plate is installed in conjunction with the top plate. The sealing component of the formwork can automatically adapt to the high-pressure environment at the bottom of the concrete mud. The greater the pressure of the concrete mud, the stronger the sealing effect, which prevents the concrete mud from leaking from the connection of the formwork and improves the quality of concrete pouring.

[0007] Furthermore, the sealing mechanism also includes a baffle and a guide column. The baffle is respectively installed between two adjacent casting panels. The guide holes in the middle of the baffle are slidably connected with guide columns. The guide columns are respectively fixedly connected to the adjacent top plates to provide guiding support for the movement of the top plates.

[0008] Furthermore, the sealing mechanism also includes a slide groove and a slide plate. The slide grooves are respectively arranged inside the baffle. The slide plates are horizontally slidably connected inside the slide grooves. The slide plates correspond to the extrusion plates one by one. The slide plates are respectively fixedly connected to adjacent extrusion plates to provide guide support for the movement of the extrusion plates.

[0009] Furthermore, the surface of the casting panel is provided with a connecting plate, which is an L-shaped plate. The baffle is located between the horizontal plate of the connecting plate and the casting panel. Bolts are inserted into the sockets on the surface of the baffle, and the bolts are threadedly connected to the screw holes on the surface of the baffle, which facilitates the connection between the sealing component and the casting panel.

[0010] Furthermore, the sealing mechanism also includes a connecting rubber pad, which is respectively arranged between two sealing rubber pads in the same group. The connecting rubber pad is fixedly connected to the top plate at the side away from the casting space to improve the sealing effect.

[0011] Furthermore, the connecting frame is formed by cross-welding two types of horizontal and vertical support plates, thereby providing stable support for the casting panel.

[0012] Furthermore, the upper ends of the support columns are rotatably connected to the upper rotating frame via the first rotating shaft, and the upper rotating frames are fixedly connected to the surface of the connecting frame respectively. The lower ends of the support columns are rotatably connected to the lower rotating frame via the second rotating shaft, which facilitates the connection between the support columns and the outside.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the template for concrete pouring has the following advantages:

[0014] During the concrete pouring process, the pressure generated by the fluid concrete slurry will be applied to the surface of the connecting pad, pushing the top plate to exert an effect on the inclined surface of the extrusion plate, causing the extrusion plate to squeeze the sealing pad to deform. The greater the pressure, the tighter the fit between the sealing pad and the pouring panel. The sealing components of the formwork can automatically adapt to the high-pressure environment at the bottom of the concrete slurry. The greater the pressure of the concrete slurry, the stronger the sealing effect, which prevents the concrete slurry from leaking from the connection of the formwork and improves the quality of concrete pouring.

[0019] See also Figure 1-2 , this embodiment provides a technical solution: a formwork for concrete pouring, comprising a pouring panel 1 and a sealing mechanism 4;

[0020] Casting panel 1: There are four of them and they are perpendicular to each other in pairs. Concrete slurry is poured into the space surrounded by the four casting panels 1. After the concrete slurry solidifies, the concrete pouring is completed. The surface of the casting panel 1 is provided with a connecting frame 2. The connecting frame 2 is made of two horizontal and vertical support plates welded crosswise. While reducing material input, it provides stable support for the casting panel 1 and increases the strength of the casting panel 1. Support columns 3 are installed on the surface of the connecting frame 2. The upper ends of the support columns 3 are rotatably connected to the upper rotating frame 5 through the rotating shaft 1. The upper rotating frame 5 is fixedly connected to the surface of the connecting frame 2 respectively. The lower ends of the support columns 3 are rotatably connected to the lower rotating frame 6 through the rotating shaft 2 to provide support for the casting panel 1 so that the casting panel 1 remains in a vertical state;

[0021] Sealing mechanism 4: It includes a sealing pad 42, an extrusion plate 44 and a top plate 45. The sealing pads 42 are respectively located between two adjacent casting panels 1. The number of sealing pads 42 between two adjacent casting panels 1 is two and they form a group. The two sealing pads 42 in the same group are respectively slidably connected with the extrusion plate 44 and the top plate 45. The inclined surface of the extrusion plate 44 is installed in conjunction with the top plate 45. During the casting process, the pressure generated by the fluid concrete slurry will push the top plate 45 to move, and the top plate 45 is used to apply pressure to the inclined surface of the extrusion plate 44. Under the action, the extrusion plate 44 is pushed toward the casting panel 1 to squeeze the sealing gasket 42. The greater the pressure, the tighter the sealing gasket 42 fits with the casting panel 1, so that the sealing component automatically adapts to the pressure of the concrete mud and improves the sealing effect. The sealing mechanism 4 also includes a baffle 41 and a guide column 46. The baffle 41 is respectively installed between two adjacent casting panels 1. The guide holes in the middle of the baffle 41 are slidably connected with the guide columns 46. The guide columns 46 are respectively fixedly connected to the adjacent top plates 45 to provide guide support for the movement of the top plates 45. The sealing mechanism 4 further includes a slide groove 47 and a slide plate 48. The slide grooves 47 are respectively arranged inside the baffle 41. The slide plates 48 are horizontally slidably connected to the inside of the slide grooves 47. The slide plates 48 correspond to the extrusion plates 44 one by one. The slide plates 48 are fixedly connected to the adjacent extrusion plates 44. The slide plates 48 slide in the slide grooves 47 to provide guide support for the movement of the extrusion plates 44. The surface of the casting panel 1 is provided with a connecting plate 7. The connecting plate 7 is an L-shaped plate. The baffle 41 is located between the horizontal plate of the connecting plate 7 and the casting panel 1. The plug on the surface of the baffle 41 Bolts 49 are inserted into the holes, and the bolts 49 are threadedly connected to the screw holes on the surface of the baffle 41. The baffle 41 is used to connect two adjacent casting panels 1 to make the position between the casting panels 1 more accurate. The sealing mechanism 4 also includes a connecting rubber pad 43, and the connecting rubber pad 43 is respectively arranged between the two sealing rubber pads 42 of the same group. The connecting rubber pad 43 is fixedly connected to the top plate 45 away from the side of the casting space, and the two sealing rubber pads 42 of the same group are sealed to prevent concrete mud from leaking from between the two sealing rubber pads 42 of the same group.

[0022] The working principle of a concrete pouring formwork provided by the present invention is as follows: when in use, the support column 3 is used to support the pouring panel 1 to maintain a vertical state, and the gap between the two adjacent pouring panels 1 is sealed by the cooperation of the sealing rubber pad 42 and the connecting rubber pad 43 to prevent leakage of concrete mud, and the concrete mud is poured into the space surrounded by the four pouring panels 1. After the concrete mud solidifies, the pouring of concrete is completed. During the concrete pouring process, the pressure generated by the fluid concrete mud will be applied to the surface of the connecting rubber pad 43, and the guide column 46 is connected to the guide sliding connection of the baffle 41 surface to support the movement of the top plate 45, pushing the top plate 45 to move. The top plate 45 exerts an action on the inclined surface of the extrusion plate 44, pushing the extrusion plate 44 toward the pouring panel 1 to squeeze the sealing rubber pad 42. The greater the pressure, the tighter the fit between the sealing rubber pad 42 and the pouring panel 1, so that the sealing component automatically adapts to the pressure of the concrete mud, improves the sealing effect, and prevents the concrete mud from leaking from the connection of the pouring panel 1.
