Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cantilever scaffolding fixing technology, specifically a pre-embedded component structure for fixing cantilever steel beams. Background Technology
[0002] Currently, when constructing embedded parts for cantilever scaffolding, the anchoring ends of the cantilever steel beams are generally fixed using U-shaped steel bar rings or portal-shaped steel plates. U-shaped steel bar rings are disposable, resulting in material waste. Portal-shaped steel plates offer reusability but cause structural damage and require further structural repairs. In recent years, with rising labor costs, these repair costs have also increased. Some residential buildings use composite slabs; when installing embedded parts, holes must be drilled in the composite slabs to insert the embedded parts from the bottom. After removal, the holes still need to be repaired and waterproofed. To address this issue, this utility model proposes a structure for fixing embedded parts to cantilever steel beams. Summary of the Invention
[0003] The purpose of this utility model is to propose a structure for fixing embedded parts of cantilever steel beams to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded component structure for fixing a cantilever steel beam, comprising a pre-embedded anchor, wherein the pre-embedded anchor is a U-shaped structure and is poured into the concrete along with the floor slab during concrete pouring; the two ends of the pre-embedded anchor protruding from the concrete are the exposed ends of the anchor; a threaded sleeve is screwed onto the exposed end of the anchor, the threaded sleeve is a hollow tube with threads on its inner wall and is screwed onto the exposed end of the anchor; an exposed connector is screwed onto the other end of the threaded sleeve, one end of the exposed connector is screwed onto the threaded sleeve, and a steel pressure plate is installed on the other end; a cantilever steel beam is welded onto the steel pressure plate.
[0005] Preferably, the pre-embedded anchor is made of steel bar with a diameter of 18mm, cold-bent into a U-shaped structure, and the exposed end of the pre-embedded part has a length of 40mm-50mm and is made with a straight thread threading process.
[0006] Preferably, the exposed connector is made of round steel with a diameter of 18mm and a length of 230mm. The end of the exposed connector that connects to the threaded sleeve is threaded by straight threading, and the other end of the exposed connector is threaded by thread rolling process using a thread rolling machine.
[0007] Preferably, one end of the exposed connector passes through the steel pressure plate and is screwed with a fixing nut.
[0008] Compared with the prior art, the beneficial effects of this utility model are: by casting the pre-embedded anchors into the concrete, the threaded sleeves and exposed connectors can be reused, avoiding the risk of subsequent building leakage caused by drilling holes in the composite slab, and saving the installation cost of steel cantilever scaffolding.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Referring to Figure (1), a cantilever steel beam fixing embedded part structure includes an embedded anchor 1. The embedded anchor 1 is a U-shaped structure and is poured into the concrete together with the floor slab during concrete pouring. The two ends of the embedded anchor 1 that protrude from the concrete are the exposed ends 11 of the anchor. A threaded sleeve 2 is screwed onto the exposed end 11 of the anchor. The threaded sleeve 2 is a hollow tube with threads on its inner wall and is screwed onto the exposed end 11 of the anchor. An exposed connector 3 is screwed onto the other end of the threaded sleeve 2. One end of the exposed connector 3 is screwed onto the threaded sleeve 2, and a steel pressure plate 4 is installed on the other end. A cantilever steel beam is welded onto the steel pressure plate 4.
[0013] The pre-embedded anchor 1 is made of 18mm diameter steel bar cold-bent into a U-shaped structure. The exposed end 11 of the pre-embedded part is 40mm-50mm long and is threaded using a straight threading process. The exposed connector 3 is made of 18mm diameter and 230mm long round steel. One end of the exposed connector 3 that connects to the threaded sleeve 2 is threaded using a straight threading process, and the other end of the exposed connector 3 is threaded using a thread rolling machine. One end of the exposed connector 3 passes through the steel pressure plate 4 and is screwed with a fixing nut 5.
[0014] When using this device, before concrete pouring, the pre-embedded anchor 1 is connected to the steel mesh of the floor slab with wire. After the concrete is poured, the exposed end 11 of the anchor is exposed in the concrete layer. One end of the exposed connector 3 is screwed to the threaded sleeve 2. Full welding can also be performed at the joint between the threaded sleeve 2 and the exposed connector 3. Then, the other end of the threaded sleeve 2 is connected to the exposed end 11 of the anchor. The steel pressure plate 4 and the cantilevered steel beam welded to the steel pressure plate 4 are installed on the exposed connector 3. Scaffolding can then be erected on the cantilevered steel beam. The connection between the exposed connector 3 and the threaded sleeve 2 can be reused multiple times, saving costs and reducing the risk of leakage by eliminating the need for drilling.
[0015] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
