Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a casting template at a beam-column node in a support-free system of an assembled building. Background Art

[0002] In the existing prefabricated support-free structure, during the installation of the beam-column node formwork, it is generally necessary to use the formwork to make a mold for the corresponding concrete component, and the size of the mold needs to be the same as the concrete cross-section size, and then use square steel and tension screws to fix the formwork. During the construction process, it was found that the lifting accuracy of the prefabricated beam-slab integrated components was low. This is the main factor of inaccurate positioning of prefabricated components and the lack of unlimited positioning devices, which will lead to deviations between the actual position and the designed position. This deviation will cause the joints of the two beam-slab integrated components to be too large or too small, resulting in the inability to install.

[0003] There are other problems when using tension screws for construction. The steel bars are dense at the beam-column joints, and the tension screws will pass through the entire column and extend out of the two opposite sides of the column. In addition, tension screws must be set on each opposite side of the column. This structural setting that passes through the column may interfere with the normal positioning and binding of the column longitudinal reinforcement and the beam longitudinal reinforcement. At the same time, the through-type design of the tension screws can stably position the formwork, but after the column is finally formed, the shear resistance of the core area of ​​the node will be weakened to a certain extent. When wooden formwork is used for construction, the sides cannot be effectively fixed, and leakage and misalignment are likely to occur, which will bring inconvenience to construction and reduce the casting strength of the column.

[0004] Based on this, the utility model designs a casting template at the beam-column node in the support-free system of an assembled building to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a casting template for the beam-column node in the support-free system of an assembled building. The device is installed in advance by limiting the position through positioning bolts, so that the installation accuracy of the integrated beam-slab component is high, the construction is simpler, the operation difficulty is effectively reduced, and the component can be recycled and reused. Moreover, outside the core area of ​​the beam and column, a through-type locking structure is not used. Instead, the main beam component and the secondary beam component are effectively supported by the support plate and the reinforced beam support, forming a triangular force system to achieve the effect of effective and stable support without affecting the overall structural strength of the cast-in-place column. A detachable reinforced beam support is used as the supporting structure. After the casting of the building components is completed, the reinforced beam support can be dismantled as a whole for recycling. The device is constructed with standardized templates, and the splicing is more accurate and tight, achieving the effect of seamless splicing, and effectively avoiding quality problems such as leakage and misalignment.

[0076] And every reinforcing beam support 4's side wall adds the support plate 3, the support plate 3 also needs to be locked with column 21 through locating bolt 5, and locating bolt 5 is screw rod, and when reinforcing beam support 4 and support plate 3 are locked with column 21, locking can be carried out through the locking hole 52 and nut of setting.

[0077] Then the secondary beam component 2 and the main beam component 22 are erected on the top of the reinforcing beam support 4, and the secondary beam component 2 and the top plate 23 are an integrated beam plate, the top plate 23 is erected on the top of the main beam component 22 and the secondary beam component 2, and the top of the main beam component 22 and the secondary beam component 2 needs to be on the same plane to ensure that the top plate 2 is horizontal.

[0078] Then the left formwork 1 is locked on the left reinforcing beam support 4 and the left support plate 3, and the right formwork 11 needs to be erected on the right reinforcing beam support 4 and the right support plate 3, and the joint is sealed by the spacer plate 12 to avoid slurry leakage.
