Description

Technical Field

[0001] This utility model belongs to the technical field of precast beam installation components, and in particular relates to an installation and fixing device for pre-embedded connecting parts in the production of precast beam components. Background Technology

[0002] Precast concrete components are typically prefabricated building components cast in reusable molds. These components are generally pre-cured within the molds, demolded, and then transported to the construction site for assembly. This process involves hoisting the components from the mold to a storage area in the factory, from the storage area to a transport vehicle, and from the transport vehicle to the construction site. For ease of hoisting, round-headed lifting nails are pre-embedded in the precast concrete components, based on their shape, size, and weight, serving as hoisting points. Using these round nails in conjunction with lifting equipment simplifies the component production process and facilitates hoisting operations.

[0003] As disclosed in the prior art, patent CN209703708U presents a "positioning device for pre-embedded hanging nails in precast components," comprising two fixed seats, at least one cantilever beam, and a connector for mounting on the cantilever beam. The two fixed seats are respectively placed on both sides of the precast component forming mold located in the casting cavity, forming a suspension space for the cantilever beam between the two fixed seats. The connector is used to fix the rubber part at the upper end of the pre-embedded hanging nail. With this structure, the accuracy of the lifting point position is improved, and the positioning efficiency of the hanging nail is greatly enhanced. After the concrete is poured and solidified, the cantilever beam can be pulled to remove the rubber part, saving time and effort. The rubber part is subjected to more uniform force, resulting in a better appearance quality of the finished product, and no secondary finishing is required after removing the fixture.

[0004] In the existing technology, the installation and fixing devices for the pre-embedded connectors are only fixed to the connection point between the fixing device and the hanger outside the casting cavity, while the bottom of the hanger is suspended. Therefore, if the head of the hanger shakes during the casting and solidification process, it will cause the lifting point to shift, affecting the subsequent hoisting construction. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an installation and fixing device for pre-embedded connecting parts in the production of precast beam components, which facilitates the adjustment of the horizontal and depth positions of the lifting points in the casting cavity, and at the same time further fixes the lifting rods.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A precast beam component production embedded connector installation and fixing device is provided, including a load-bearing angle steel fixed to the upper surface of the beam steel template and an embedded connector fixed at one end to the inner side wall of the beam steel template. The load-bearing angle steel is provided with vertically arranged steel hangers. The lower part of the steel hangers is fixedly connected to the other end of the embedded connector. One side of the horizontal plane of the load-bearing angle steel is an open grid. The opening size of the open grid matches the outer diameter of the steel hangers. Several layers of horizontally arranged round steel are welded along the height direction on the upper part of the steel hangers. The spacing between adjacent horizontal round steels matches the thickness of the load-bearing angle steel. At least two steel rings are welded to the lower part of the steel hangers via connecting round steel. The embedded connector includes a vertically arranged open end plate. The open end plate is welded to at least two angle-welded connecting plates. Several horizontally arranged connecting plate end reinforcing bars are welded to the angle-welded connecting plates. The connecting plate end reinforcing bars pass through the steel rings.

[0007] Preferably, each end of the horizontal plane of the load-bearing angle steel is provided with a vertically downward welded steel plate. The welded steel plates are fixed to the outer walls of both sides of the beam steel formwork by screws, and the horizontal plane of the load-bearing angle steel is fixed to the upper surface of the beam steel formwork by bolts and nuts.

[0008] Preferably, two parallel load-bearing angle steels are fixed to the beam steel formwork by bolts, and two steel hangers are snapped onto each load-bearing angle steel. The pre-embedded connectors below the steel hangers are arranged perpendicularly to the load-bearing angle steels and connected to the adjacent inner sidewall of the beam steel formwork.

[0009] Preferably, the two angled welded connecting plates are perpendicular to each other, and each angled welded connecting plate is welded with a connecting plate end steel bar, the end position of the connecting plate end steel bar matching the position of the steel ring.

[0010] Preferably, one side of the angled welded connecting plate has a tail bar extending outward, and the length direction of the tail bar is parallel to the length direction of the end bar of the connecting plate.

[0011] The beneficial effects are as follows: This utility model controls the horizontal position of the lifting point in the casting cavity by fixing the load-bearing angle steel and the snap-fit ​​position of the steel hanger in the perforated grid, and controls the depth position of the lifting point in the casting cavity by adjusting the round steel stop on the steel hanger. After determining the position of the lifting point, the bottom end of the steel hanger is completely fixed in the casting cavity by the pre-embedded connector, thus realizing a simple, efficient, stable and reliable prefabricated component assembly and production process.
