Description
Technical Field
The invention relates to the technical field of building construction, in particular to a corner conversion device.
Background
The facilities such as cantilever frame, attached lifting scaffold, creeping formwork, building machine, etc. are widely used in construction, and the bearing support is difficult to be reasonably realized due to the particularity of the corner of the building and the limitation of position space. In order to meet the safety requirement, the traditional overhanging scaffold stretches the section steel into the building at the corner of the building to form a support, so that the material consumption is large, the local structure is damaged, the internal space is occupied, and the next procedure construction is hindered; the corner arrangement of a building is avoided, the load is carried by a complex force transmission mechanism, and the stress and the process are complex; finally, the hole needs to be repaired, and the hidden troubles of cracks and water leakage are easily caused. When reserving a plurality of accurate bolt holes in pairs in building bight structure, because of reasons such as fixed technology is not good enough, concrete placement vibrates, buried sleeve warp, the pore takes place relative deformation easily, and is difficult to the bearing member installation that has the requirement of accurate pore, and it is very difficult to trompil in pairs at building bight again in the later stage.
The title of the academic thesis of the university of western' an architecture science and technology, "development and research of novel bearing members of cantilever frame for building construction", author: forest loyalty, open date: in 5 months of 2015, pages 17 to 20 of the article relate to corner special members, two steel plates are welded into an L shape in a 90-degree crossed mode to form corner member end plates, and vertical reinforcing ribs and horizontal reinforcing ribs are welded on the corner member end plates to form corner members. This patent has the following problems: 1) although the welding structure of the vertical reinforcing rib and the horizontal reinforcing rib of the scheme eliminates stress to a certain extent, the corner component is used as a part of the cantilever frame bearing component, the end plate surface of the L-shaped corner component is used as a main component of the corner component, and is a main bearing surface of the cantilever frame bearing component relative to the corner shear wall, the problem of stress concentration still exists, and if the two steel plates forming the end plate of the corner component have problems in self structure or welding, deformation may occur during use, and the potential safety hazard is formed. 2) The corner component is formed by welding the steel plate and the reinforcing rib, and the size design requirements of the reinforcing rib and the steel plate are strict for eliminating the stress problem, so that the processing and the manufacturing are time-consuming, and the rapid processing, the manufacturing and the installation cannot be realized. 3) Due to the structure formed by the split welding combination, if the welding process has the condition of insufficient welding and the like, great potential safety hazards are generated. 4) The corner component is formed by welding reinforcing ribs and steel plates except for the structural structure of the corner component, the I-shaped steel is welded on the end face of the corner component to be connected with the cantilever frame main body, the end face of the corner component is in an L shape formed by welding two steel plates, and bearing load is completely concentrated on the end face of the corner component, so that the problem of stress concentration of the end face of the corner component is further aggravated, and potential safety hazards exist.
Chinese invention patent, grant publication number: CN 206957185U; the date of authorized announcement: 2 months and 2 days in 2018; discloses a connecting piece for fixing cantilever frame section steel. This connecting piece includes screw rod, nut, external corner fastener, reentrant corner fastener, the external corner fastener is installed in building external corner shear force wall outside, the reentrant corner fastener is installed in building external corner shear force wall inboard, through the screw rod passes the bushing who buries in building external corner post in advance, adopts the nut is fixed, and building external corner shear force wall outside the external corner fastener is connected with the frame shaped steel of encorbelmenting. However, the scheme does not fully consider the actual construction requirement, and has the following technical problems: 1) the external corner clamping piece and the internal corner clamping piece are formed by welding steel plates, the stress concentration problem caused by welding is eliminated, the welding quality requirement is high, the size design requirement is high, the machining and manufacturing are time-consuming, and quick machining, manufacturing and installation cannot be realized. 2) The stress component is used as a stress component of the cantilever frame main body, the main stress part of the scheme is the contact position of the steel plate section forming the male corner piece and the female corner piece and the corner shear wall, and the requirement on the deformation quantity of the steel plate forming the male corner piece and the female corner piece is high; 3) because of its structural style that the combination formed, external corner fastener and reentrant corner fastener are as the atress part, during the processing preparation, and the quality requirement is high, otherwise can have very big potential safety hazard, cause the preparation cycle length, can't realize quick processing preparation installation.
