Description

A construction protection frame

technical field

The utility model relates to a building construction protective frame, in particular to a protective frame in the construction stage of a building main body. the

Background technique

The building construction protective frame is mainly used for safety protection in the main construction stage of high-rise and super high-rise buildings. The current protective frame is mainly composed of a single-row frame body and a vertical truss. The vertical truss is used as the frame body to meet the load-bearing requirements. , the protective frame is connected with the embedded parts on the building through load-bearing legs and anti-roll bars, and transmits the self-weight and construction load of the protective frame to the building. Such a plurality of frame units are arranged on the building in pieces to form a closed frame surrounding the outer contour of the building, and provide edge protection for the building under construction. As the building rises one floor higher, the tower crane is used to lift the protective frame up one floor and fix it with the building again. Although the above-mentioned protective frame is simple in structure and low in cost, it has certain economic benefits. But there are also some disadvantages:

1. Due to the size and weight of the vertical truss, a tower crane must be used during installation, which is prone to collision during hoisting and brings danger to the installation and construction personnel.

2. This protective frame is connected to the building by the vertical truss through load-bearing legs and anti-roll bars. The outer single-row frame body is only connected to the vertical truss, and is not directly connected to the load-bearing legs and anti-roll bars. , because the vertical truss is connected to the single-row frame body through fasteners, and the connection points are all on the same plane. Once the fasteners are accidentally loosened, it is easy to cause the vertical truss to separate from the frame body, causing the scaffold to fall and cause accidents. . the

3. The vertical truss used consumes more steel and wastes resources. the

Contents of the invention

The purpose of the utility model is to provide a construction protective frame, which has simple structure, convenient installation, high safety, and saves materials. It does not need to use a tower crane during installation, effectively avoids the collision between the vertical truss and the frame body, and provides protection for safe production. convenient. the

The purpose of the invention of the utility model adopts the following technical solutions to realize:

The construction protection frame proposed by the utility model includes a load-bearing truss device, an anti-tilt device and a load-bearing frame body. The frame body adopts a traditional double-row frame body, and the double-row frame body can be an existing fastener type steel pipe scaffold, Bowl buckle scaffolding or scaffolding structure composed of other shaped rods, the load-bearing truss device and the anti-tilt device are connected to the double-row frame body to transfer the load of the frame body to the building; the load-bearing truss device includes a load-bearing truss and a load-bearing arm, the load-bearing arm is connected to the load-bearing truss; the anti-tilt device includes a horizontal tie rod and a fixed rod, and the fixed rod is fixed to the inner and outer rows of vertical rods of the frame body at multiple points, and the horizontal tie rod is connected between the fixed rod and the building. This protective frame first improves the frame body, removes the vertical truss, and adopts a non-single-row frame body, which is easy to build and does not need to use a tower crane. At the same time, in order to ensure that the frame body effectively transmits its own weight and load to the building, and to ensure the safety and stability of the connection with the building, a special structure of the load-bearing truss device is adopted, and the load-bearing truss device is connected to the frame body. Both the inner and outer rows of uprights are connected and fixed.

In order to further ensure the firmness of the connection between the load-bearing truss and the frame body, the utility model also reasonably designs the connection points of the load-bearing truss to ensure that the load-bearing truss is connected and fixed to the inner and outer row poles of the frame body through multiple connection points. The load-bearing truss adopted by the utility model can be any existing feasible form, more generally, it can be a triangular truss, a rectangular truss, and of course it can also be a truss of any other foreseeable structure, as long as it can reach the inside and outside of the frame body. Rows of uprights are connected for the purpose of transmitting force. the

The load-bearing arm can be a straight arm structure. Considering that the protective frame should avoid collision with the building during the lifting process, the load-bearing arm is designed to be connected in parallel with the load-bearing truss, and make it horizontally expandable relative to the load-bearing truss. One end of the load-bearing arm is put into the load-bearing truss sleeve or sleeve, and the other end is connected to the embedded ring of the building to transfer the load on the frame body to the building, and in order to position the telescopic load-bearing arm , and at the same time enable the entire load-bearing truss device to better transmit force, and hinge and position the tie rod between the load-bearing arm and the load-bearing truss. the

The load-bearing arm can also be in the form of a triangular arm, which is hinged with the load-bearing truss through the lug plate. the

The fixed rod of the anti-rolling device is a horizontal rod or a Z-shaped rod, and the fixed rod is connected with the inner and outer vertical rods of the frame body. the

In summary, it can be seen that the utility model has the following advantages:

1. The frame body of the utility model has no vertical truss, but adopts the usual double-row frame body, which has the advantages of simple structure, light weight and easy construction. During the construction process of the protective frame, it can be realized without using a tower crane Installation and construction are more convenient and faster.

2. Both the load-bearing truss device and the anti-tilt device of the utility model are fixedly connected to the vertical poles of the two planes inside and outside the frame body at multiple points. Compared with the existing single-plane installation structure, it has a more reliable force-bearing structure. Therefore, it has higher security. the

3. When lifting the protective frame, the positioning rod between the load-bearing truss and the load-bearing arm can be temporarily disengaged, so that the load-bearing arm moves away from the wall relative to the load-bearing truss, which can effectively avoid the protruding outer contour of the building and reduce the Collision hazard. the

4. The frame structure of the utility model can adopt the usual scaffolding structure, and the vertical trusses are omitted, which can save 51% of steel materials compared with the prior art, and achieve the effect of energy saving and emission reduction. the

5. The anti-tilt device of the present utility model is designed taking into account the protection of the safety net. If the "Z" type fixed rod can be used as required, the connection point between the "Z" type fixed rod and the outer row of vertical rods can be positioned at The intersection of the safety nets of the two protective frames avoids the problem of breaking through the safety nets due to horizontal connections, and can protect the safety nets that need to be recycled. the
