[0002] In building structures, high-rise structures often use steel-reinforced concrete columns, and at the same time set up oblique supports or horizontal rigid connections; in ordinary buildings, if oblique supports are set up, the connection nodes between the supports and beams and columns are set up; if steel connections are set up, the node plates are directly connected to the steel; then this steel structure component is buried in reinforced concrete, and the concrete side or bottom surface needs to be supported by formwork for pouring, and the formwork needs to be processed according to the shape of the component, so the processing of the formwork is difficult and the construction period of the formwork is long; and there are shortcomings such as the joints between the formwork and the steel component are not tight, and it is easy to leak slurry;

[0003] In super high-rise buildings, large formwork and climbing formwork are used, and special-shaped steel components are buried in reinforced concrete structures. Therefore, large formwork and climbing formwork need to be specially set up according to the special-shaped components, and the formwork is scrapped after use, which causes great waste.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides an embodiment 1: a steel formwork structure for reducing the application of special-shaped formwork, including a concrete upper pier 1 of a vibration isolation equipment layer and an embedded steel member 2, the interior of the embedded steel member 2 is welded with multiple groups of internal closed steel formworks 3, the exterior of the embedded steel member 2 is welded with external lap steel formworks 4, and the multiple groups of internal closed steel formworks 3 are connected to the external lap steel formworks 4, and the exterior of the external lap steel formworks 4 is spliced ​​with a concrete upper pier bottom wood formwork 5.

[0027] The embedded steel member 2 is a cross-shaped steel column structure, and four groups of through holes are opened at the bottom of the embedded steel member 2 for easy connection; multiple groups of bolts are longitudinally arranged and welded at the four corners of the outer side of the embedded steel member 2, and the multiple groups of bolts are located above the internal closed steel formwork 3; the external lap steel formwork 4 is a rectangular frame structure, which is used to connect the internal closed steel formwork 3 and the concrete upper pier bottom wooden formwork 5.

[0028] As attached Figure 1 As shown, when the embedded steel member 2 is inserted into the concrete upper pier 1 of the vibration isolation equipment layer, the template is supported according to the shape of the cross-shaped steel column embedded steel member 2 and the concrete embedding surface. In this way, the template processing is complicated and the support and erection of the template are troublesome. If the support is not firm, concrete or gravel may fall during pouring, affecting the operation of the equipment; if the template joint gap is not tight, the concrete slurry will flow onto the equipment layer during pouring, or flow along the gap to the lower layer, affecting the equipment;

[0029] Example 2

[0030] like Figure 6-9As shown, the oblique support connecting steel node 9 is embedded in the concrete beam column, and the column formwork needs to be supported according to the shape of the node plate. When the node is complex and the size of the node is different, the same wooden formwork processing and joint problems as described in Example 1 are faced, and there is a problem of collision between the stirrups of the concrete column 6 and the node plate. When the stirrups are opened on the node plate, the node plate is weakened. The node plate needs to be enlarged to meet the requirements during the node design, which increases the node usage; when the stirrups are directly welded to the node plate, the welding affects the steel performance of the node plate and the connection strength of the node;

[0031] Generally, the connection of inclined steel supports also has embedded parts, and then the node plates are welded to the embedded parts. Although this facilitates on-site construction, it increases the workload of on-site welding and increases costs.

[0032] The steel formwork 10 is welded on the node plate. The steel formwork 10 can be used as a formwork. The column stirrups can also be welded to the steel formwork 10. The steel formwork 10 serves as a steel bar connecting plate.

[0033] Example 3

[0034] like Figure 10-13 As shown, the upper connection node of the oblique support is embedded in the concrete beam 7 or connected to the upper concrete beam column, and the bottom formwork of the beam needs to be supported according to the shape of the node plate. When the node is complex and the sizes of the nodes are different, the same wooden formwork processing and joint problems as in Case 1 are faced. At the same time, the problem of collision between the stirrups of the concrete beam and the node plate, when holes are drilled for the stirrups on the node plate, the node plate is weakened. The node plate needs to be enlarged to meet the requirements during node design, which increases the node usage; when the stirrups are directly welded to the node plate, the welding affects the steel performance of the node plate and the connection strength of the node; generally, the connection of the oblique steel support also has embedded parts, and then the node plate is welded to the embedded parts, then the upper node welding is on-site overhead welding, which is difficult to operate on-site, the weld quality cannot be guaranteed, and the welding work is also done at high altitude, which increases the welding workload and costs.

[0035] The utility model adopts welding of steel template 10 on the node plate, the steel template 10 can be used as a template, and beam stirrups can be welded to the steel template 10, and the steel template 10 serves as a steel bar connecting plate.

[0036] Working principle: The utility model adopts welding an internal closed steel formwork 3 inside a cross-shaped steel column and welding an overlapping formwork 4 outside the column; the integral steel structure formwork formed in this way reduces the processing of irregular-shaped wooden formworks and also serves as a formwork; the steel formwork and the wooden formwork are overlapped to facilitate on-site construction, and the joints are tight and leak-proof.
