Description

Technical Field

[0001] This utility model relates to fixing devices, and particularly to fixing devices for external scaffolding of high-rise concrete frame structures. Background Technology

[0002] When residential buildings have relatively low floors, scaffolding construction can be carried out using wall ties as required by specifications, which meets the construction requirements. However, most industrial plants are large-span, high-rise buildings, especially reinforced concrete structures with floor heights exceeding 5 meters. During construction, the number of wall ties installed according to specifications is often insufficient, failing to meet the lateral support strength requirements for high-rise scaffolding. Furthermore, the lack of wall tie points in the middle of structural floors due to their height and large spans leads to insufficient lateral stability of the scaffolding, posing serious safety hazards. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fixing device for external scaffolding of high-rise concrete frame structures. This device can provide connection points for wall ties of external scaffolding to ensure the lateral connection strength of the scaffolding.

[0004] In order to solve the technical problems existing in current construction, this utility model adopts the following technical solution:

[0005] This utility model discloses a fixing device for external scaffolding of high-rise concrete frame structures, comprising steel plate embedded parts arranged vertically and embedded in each floor slab, wherein the steel plate embedded parts on two adjacent floor slabs are fixedly connected by steel sections arranged vertically; the external scaffolding is fixedly connected to the outer side of multiple steel pipe wall ties arranged vertically and at intervals, and the inner ends of the multiple steel pipe wall ties are fastened to the steel sections at corresponding positions by fasteners or fixedly connected to the vertical bars on the frame columns arranged on the outer side of each floor slab.

[0006] The beneficial effects of this utility model are:

[0007] (1) By setting vertical steel sections between layers, this utility model provides a stable and reliable wall connection point for the external scaffolding of this layer, thus solving the problem of insufficient wall connection components caused by excessive floor height.

[0008] (2) This utility model solves the problem that steel profiles cannot be firmly fixed to the floor slab by setting up floor embedded parts, and provides an effective fixing structure.

[0009] (3) This utility model adopts the combination of embedded parts and steel sections as fixing points for external scaffolding. The steel sections can be reused, avoiding the material waste caused by one-time material input and saving materials.

[0010] (4) This utility model is easy to use, simple to operate, and does not affect the construction progress.

[0011] (5) The fixing device provided by this utility model effectively provides safety protection for external scaffolding, avoids safety hazards caused by the lack of effective fixing of external scaffolding in conventional construction, and reduces safety risks.

[0012] (6) Frame erection is widely used in frame, frame-shear and mixed multi-story building structures in construction engineering. High-rise frame erection requires the installation of wall ties. Therefore, this utility model has a wide range of applications and is not limited to this. Other similar structures that require ties but do not have finite ties can also be used.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, the present invention provides a fixing device for external scaffolding of high-rise concrete frame structures, including steel plate embedded parts 1 which are respectively arranged at the upper and lower positions and embedded in each floor slab 6. The steel plate embedded parts 1 on two adjacent floor slabs are fixedly connected by steel sections 2 arranged in the vertical direction.

[0017] like Figure 2 As shown, the upper and lower ends of the steel section 2 are connected to the steel plate embedded parts 1 on the floor slab and the corresponding top plate of the floor slab, respectively. Welding is the preferred connection method. The steel plate embedded parts 1 and the steel section 2 together form a whole that is securely connected to the frame structure, providing reliable support points for the external scaffolding. The external scaffolding is fixedly connected to the outer sides of multiple parallel steel pipe wall ties 3. The inner ends of the multiple steel pipe wall ties 3 are fastened to the corresponding positions of the steel section 2 using fasteners or fixedly connected to the vertical reinforcement bars on the frame columns 7 on the outer side of each floor slab 6. The structure formed by the steel plate embedded parts 1 and the steel section 2 provides safe and reliable wall connection points for the external scaffolding.

[0018] The external scaffolding can be composed of external scaffolding horizontal bars 4 and external scaffolding vertical bars 5.

[0019] The plane position of the steel plate embedded part 1 can be set according to the requirements of the wall connection points of the external scaffold. It can be pre-embedded at the corresponding position on the floor plane to ensure that it corresponds to the connection position of the external scaffold.

[0020] The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of this invention without departing from the spirit and scope of the claims, and these modifications are all protected by this invention.
