There are two second supporting steel beams. A supporting steel beam is symmetrically distributed in the middle to form a cross-shaped supporting structure, and the supporting steel beam is perpendicular to the cross-shaped supporting structure, and the I-shaped surface at one end is welded to the center of the cross-shaped supporting structure. The reinforced steel beams are provided with four, respectively along the four sides of the supporting steel beams, and the cross sides of the cross-shaped support structure below are constructed to form a right-angled triangle super-static structure, thereby forming a quadrangular pyramid-shaped super-static structure. fixed system.

Through the support steel beam of the quadrangular pyramid-shaped statically indeterminate system as the main shaft support beam and the steel structure, four reinforced steel beams are used as the zero bar in the statically indeterminate structure, and the unloading of the supporting steel beam as the main shaft is carried out. The load capacity is enhanced, and the cross-shaped supporting structure constructed by the first supporting steel beam and the second supporting steel beam is used as the chassis support to connect with the tire frame. Due to the design of the above-mentioned structure, the steel consumption of the support system of the tire frame can be reduced, and the unloading capacity and stability of the unloading tool can be improved at the same time, and it is convenient to set up and disassemble with the tire frame, so as to improve the efficiency of building construction.

Further, the second supporting steel beam is selected from the same type of I-beam as the first supporting steel beam, and the leg width of the supporting steel beam is less than or equal to that of the first supporting steel beam.

Further, the supporting steel beams and supporting steel beams are preferably 28# I-beams, and the reinforcing steel beams are preferably 18# I-beams.

In some embodiments, another idea of the present disclosure is to provide auxiliary steel beams in the right-angled triangle structure composed of the supporting steel beams, reinforcing steel beams, and the corresponding cross sides of the cross-shaped support structure, for To further improve the stability of the statically indeterminate system.

specific. One end of the auxiliary steel beam is welded to the side of the reinforced steel beam, and the other end is welded to the side of the supporting steel beam and the corresponding cross side respectively, and the connection is fixed by welding.

Further, the flange surface of the auxiliary steel beam is perpendicular to the flange surface of the reinforcing steel beam.

In combination with the above ideas, the present disclosure provides a jacking tool for a tire frame support system, including: a supporting steel beam, a reinforcing steel beam, a first supporting steel beam, a second supporting steel beam; the second supporting There are two supporting steel beams, which are distributed symmetrically along the middle of the first supporting steel beam to form a cross-shaped supporting structure, and the I-shaped surfaces at one end of the two second supporting steel beams are respectively connected to the first supporting steel beam. The corresponding side of the supporting steel beam is welded; the supporting steel beam is perpendicular to the first supporting steel beam, and is welded to the center of the cross-shaped supporting structure through the I-shaped surface at one end; the reinforcing steel beam is provided with four, The I-shaped surface at one end is welded to the corresponding side of the four sides of the other end of the supporting steel beam, and the I-shaped surface at the other end is respectively welded to the flange surfaces of the four open ends of the cross-shaped support structure, A quadrangular pyramid-shaped super statically indeterminate structure is formed; a convenient disassembly structure is provided between the first supporting steel beam and the second supporting steel beam and the tire frame.

Based on the above technical solution, the present disclosure adopts the supporting steel beam as the main shaft supporting beam of the jacking tool, adopts the reinforcing steel beam as the edge of the quadrangular pyramid-shaped hyperstatic structure, and uses it as the corresponding hyperstatic right angle The zero bar of the triangular structure improves the stability of the jacking tooling, and at the same time further enhances the unloading performance of the supporting steel beam, and improves the supporting system of the tire frame through the convenient disassembly structure between the cross-shaped supporting structure and the tire frame. Adaptability to special-shaped buildings, and shorten the cycle of its construction and disassembly.

Further, the edges of the quadrangular pyramid-shaped hyperstatic structure form an included angle of 45°-60° with the horizontal plane formed by the cross-shaped supporting structure.

Based on the above-mentioned setting of the included angle, the jacking tooling structure provided by the present disclosure can be made more stable, and the unloading can be more uniform.

Further, the present disclosure also provides auxiliary steel beams, the auxiliary steel beams are arranged in a right-angled triangle structure composed of the supporting steel beams and reinforcing steel beams and the corresponding cross sides of the cross-shaped supporting structure; corresponding The auxiliary steel beam is perpendicular to the corresponding reinforced steel beam, the I-shaped surface at one end is welded to the side of any side of the corresponding reinforced steel beam, and the I-shaped surface at the other end is welded to the junction of the two right-angled sides of the corresponding right-angled triangular structure.
