Description

Technical Field

[0001] The utility model relates to the technical field of concrete moulds, in particular to a concrete top mould corner connector and a concrete mould assembly. Background Art

[0002] When pouring concrete on the top slab of a building, you first need to build the top formwork. When building the top formwork, you need to use corner connectors to connect the top formwork and the side formwork as a whole. This is to utilize the side formwork and corner connectors to restrain the top formwork, preventing it from moving during pouring, and to provide stable support.

[0003] The corner connectors currently used are mostly angle steels, with connection holes opened on the two straight sides of the angle steels, and then connected by bolts. However, there is a problem with using angle steels: in order to ensure the structural strength between two adjacent frames and the strength of the connector itself, thicker angle steels are needed to compensate for the strength, but this increases the weight of the connector itself, which causes high labor intensity for construction workers and is very strenuous during operation, which further results in a decrease in construction efficiency.

[0004] Therefore, there is an urgent need for concrete top formwork corner connectors and concrete formwork components to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a concrete top formwork corner connector and a concrete formwork assembly, which are used to solve the problem that the existing formwork corner connectors are heavy, cause high labor intensity for construction workers and affect construction efficiency.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A corner connector for a concrete top formwork, comprising a connector, characterized in that: the connector is provided with a first carrier plate, a second carrier plate is vertically provided on one side of the first carrier plate, a first connecting plate is vertically provided on the other side of the first carrier plate, and a second connecting plate is vertically provided on the other side of the second carrier plate;

[0008] The first connection plate is provided with a plurality of first reinforcement rings at equal intervals, the bottom of the first reinforcement ring is provided with a first connection hole, and both the first reinforcement ring and the first connection hole are circular;

[0009] The second connection plate is provided with a plurality of second reinforcement rings at equal intervals, the bottom of the second reinforcement ring is provided with a second connection hole, and the second reinforcement ring and the second connection hole are both rectangular;

[0010] The connecting member is located between the first carrier plate, the second carrier plate, the first connecting plate and the second connecting plate and is welded and fixed with at least one rib plate;

[0011] An operation port is provided between the first connecting plate and the second connecting plate.

[0012] Furthermore, a support plate is vertically provided on one side of the first connection plate close to the operation port.

[0013] Furthermore, the first reinforcement ring and the second reinforcement ring are at an equal distance from the end of the connecting piece, and the rib plate is located between the two first reinforcement rings.

[0014] Furthermore, the first reinforcement ring and the second reinforcement ring are an integrally stamped structure on the connecting piece.

[0015] Furthermore, one side of the first reinforcement ring is coplanar with the first connecting plate, and the other side protrudes toward the second carrier plate; one side of the second reinforcement ring is coplanar with the second connecting plate, and the other side protrudes toward the first carrier plate.

[0016] A concrete formwork assembly comprises a first formwork unit, a second formwork unit and the above-mentioned concrete top formwork corner connector, wherein the first formwork unit comprises a first frame and a first receiving plate connected to the first frame, the second formwork unit comprises a second frame and a second receiving plate connected to the second frame, the first frame comprises a first frame and a first reinforcement, and the second frame comprises a second frame and a second reinforcement, characterized in that: the first frame is matched with the first connecting plate, the second frame is matched with the second connecting plate, a third connecting hole of equal diameter is opened at a position corresponding to the first connecting hole of the first frame, a first pin is inserted between the first connecting hole and the third connecting hole, a fourth connecting hole of equal cross-section is opened at a position corresponding to the second connecting hole of the second frame, and a second pin is inserted between the second connecting hole and the fourth connecting hole.

[0017] Furthermore, a fourth connection hole is formed at a position of the first reinforcement member close to the third connection hole, and a fifth connection hole is formed at a position of the second reinforcement member close to the fourth connection hole.

[0018] Furthermore, the first pin includes a fixed end and a connecting rod, the connecting rod is provided with a first locking hole, and the second pin can be inserted into the first locking hole and the fifth connecting hole.

[0019] In summary, the beneficial technical effects of the utility model are:

[0020] (1) By setting a first reinforcement ring around the first connection hole and a second reinforcement ring around the second connection hole, the structure of the connector itself can be used to increase the structural strength of the entire connector while reducing the thickness of the connector, making it easier and faster for construction workers to operate. At the same time, the integrity of the connector is improved by adding ribs, further improving the structure.

[0021] (2) The support plate can play a supporting role when installing the first frame. The construction workers do not need to hold it up all the time, thereby reducing physical exertion. At the same time, the support plate can ensure that the end surface of the first frame is flush with the first carrier plate when it is installed to ensure the horizontality of the pouring.

[0022] (3) The first reinforcement ring and the second reinforcement ring formed by stamping the connector itself avoid the increase in weight caused by adding additional accessories, and also avoid the deformation caused by welding.

[0023] (4) By arranging the protrusions of the first reinforcement ring and the second reinforcement ring toward the inside of the connecting member, the fitting area between the first frame, the second frame and the connecting member is increased, making the assembled structure more stable.

[0024] (5) The first pin and the second pin are used to realize the quick connection between the connecting member and the first frame and the second frame, and also replace the bolt connection, thereby reducing the complexity of assembly.

[0025] (6) By using the first locking hole and the fifth connecting hole, after the first pin passes through the first connecting plate and the first frame, the second pin can be used to lock the first pin, thereby preventing the first pin from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
