TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building secondary structure construction device, and specifically relates to an open-close type concrete pouring device. BACKGROUND

[0002] In order to speed up the construction progress of the project, the construction method of completing the main frame structure first and then carrying out secondary structure construction is adopted at present. The construction of the concrete structural column in the secondary structure is very important, and it is a big problem in the construction process to realize the close connection of the structural column up and down with the main structure, ensure the overall quality and aesthetic degree of the structural column. The commonly used construction process of the structural column is to use a formwork to make a concrete pouring opening at the upper part of the structural column in order to ensure the pouring quality of the column top. After the concrete is poured and reaches the strength, the formwork is removed, and then the excess concrete at the top of the structural column is chiseled off, which will inevitably cause some loss of labor and materials. Not only is the construction process increased, but also the surface flatness and appearance of the chiseled concrete will be greatly affected. The concrete fragments after chiseling will also affect the neatness and beauty of the construction site.

In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0029] The present application provides a specific embodiment of an open-close type concrete pouring device, comprising: a fixed formwork 1, a movable formwork 2 and a sealing connecting piece 3; the lower end of the movable formwork 2 is hinged to the fixed formwork 1 through a hinge 6, and the two sides are sealingly connected to the fixed formwork 1 through the sealing connecting piece 3; when the movable formwork 2 is rotated to an acute angle with the fixed formwork 1, an unfolded state is formed, and the fixed formwork 1, the movable formwork 2 and the sealing connecting piece 3 enclose a funnel-shaped space 100 for facilitating the entry of concrete; when the movable formwork 2 is rotated to be coplanar with the fixed formwork 1, a split state is formed, and the inner sides of the fixed formwork 1 and the movable formwork 2 form a plane for shaping the concrete.

[0030] The present application provides an open-close type concrete pouring device, when the fixed formwork 1 and the movable formwork 2 are in an unfolded state, concrete can be poured through the funnel-shaped space 100 at the top, and secondary structure concrete can be poured. After pouring to the top of the structure, the movable formwork 2 is rotated to be coplanar with the fixed formwork 1 to form a split state, and the pouring opening is closed, so that the excess concrete is squeezed out and the top concrete is compacted, and the inner sides of the fixed formwork 1 and the movable formwork 2 are flush, and the concrete can be shaped. By using the open-close type concrete pouring device of the present application, the concrete surface after form removal can be smooth, and the cost of removing excess concrete by manual chiseling in the later stage is saved.

[0031] In order to make the fixed formwork 1 and the movable formwork 2 form an acute angle in the unfolded state, the included angle between the two needs to be limited, and in the present embodiment, the sealing connecting piece 3 bears and limits the movable formwork 2 when the movable formwork 2 is in an unfolded state with the fixed formwork 1. It is more convenient and easy to implement to use the sealing connecting piece 3 to bear and limit, without the need to additionally set a limiting piece and a fixing piece.

[0032] The sealing connector 3 can be implemented in various ways, as long as it can seal the sides of the funnel-shaped space 100 and is sufficient to withstand the load when concrete is poured to the top. For example, a rigid material can be set as a fan-shaped folded structure to serve as the sealing connector 3.

[0033] Preferably, the sealing connector 3 is made of a flexible material, such as plastic or rubber, which can be flexibly deformed, giving it greater freedom of choice during construction and facilitating the operation of construction personnel during unfolding or assembly.

[0034] In this embodiment, the flexible material is a rubber sheet, which has good sealing properties, as well as good elasticity and resilience. Based on its elasticity, it can provide assistance when rotating the movable template 2 and is easy to set to a smaller area, thereby reducing the volume of the sealed connector 3 in the rolled-up state when in the assembled state.

[0035] In this embodiment, a pressure plate 31 is included for installing the sealing connector 3. One end of the sealing connector 3 is fixed to the fixed template 1 by the pressure plate 31, and the other end is fixed to the movable template 2 by the pressure plate 31. The pressure plate 31 can flatten the edge of the flexible material, including the rubber sheet, so that the installation of the sealing connector 3 is more stable and the sealing performance is enhanced.

[0036] In some embodiments of this application, the lower end of the pressure plate is lower than or flush with the lowest point of the funnel-shaped space 100, so that the sealing connector 3 covers the entire side of the funnel-shaped space 100, preventing concrete leakage during the pouring process. In this embodiment, the lower end of the pressure plate is 10mm lower than the lowest point of the funnel-shaped space 100.

[0037] In this embodiment, a pin 4 is included, which includes a pin body 41 and a pin sleeve 42. The pin body 41 also includes a positioning post 411 extending vertically from the main body. The pin sleeve 42 is separately disposed on the outside of the fixed template 1 and the movable template 2. The fixed template 1 also includes a stop post 43. When the template is assembled, the pin body 41 is inserted into the pin sleeve 42, and the positioning post 411 is blocked by the stop post 43 to fix the fixed template 1 and the movable template 2 and maintain the assembled state for shaping the concrete.

[0038] To avoid excessive load on the funnel-shaped space 100 when it contains a lot of concrete, which would exceed the bearing capacity of the sealing connector 3, and to facilitate the calculation of the concrete volume of the funnel-shaped space 100, in this embodiment, a limiting support 5 is fixedly installed on the outside of the fixed template 1. The limiting support 5 supports the movable template 2 when the movable template 2 is rotated to a specific maximum unfolding angle.

[0039] In some embodiments, the maximum unfolding angle is 45 degrees to 75 degrees, so as to take into account the size of the space for pouring concrete and the difficulty of implementing the sealing connector 3. In the present embodiment, the maximum unfolding angle is 60 degrees.

[0040] In the present embodiment, the fixed template 1 is provided with an indicating line for indicating the height of the concrete. The indicating line can be used to prompt the volume of concrete in the void space 100 and in the secondary structure column, so as to facilitate the personnel using the present application to determine the timing of extruding concrete by rotating the movable template 2.

[0041] In summary, the open-close type concrete pouring device provided by the present application is light and flexible, convenient to use, can be made of conventional wooden templates on site, all components are located on the outer side away from the concrete, and can be quickly fixed on the template body by means of screw threads and the like, can be quickly made and put into use when needed, saves time and labor, and can be repeatedly used. By using the open-close type concrete pouring device, labor and concrete materials can be saved, and the economy is good.

[0042] The above-described content can be implemented individually or in various combinations, and these variants are within the protection scope of the present application.

[0043] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
