Definitions

  • the application belongs to the field of construction auxiliary components for large-span structures, and particularly relates to a sliding support self-dispersing auxiliary device for large-span truss construction.
  • the traditional method of large-span truss construction is to use short steel pipe columns to directly contact the bottom chord of the truss at the contact point between the top of the assembled tire frame column and the truss.
  • traditional short steel pipe columns can support the truss
  • jacks are required to lift the truss before it can slide, and space must be reserved for the placement of the jacks before the truss assembly , Time-consuming and laborious, increasing the cost of construction.
  • the purpose of the present application is to provide a large-span truss construction sliding support self-dispersing auxiliary device that can facilitate direct sliding after the truss is assembled, enhance the friction of the contact part, and reduce the amount of supporting structure steel.
  • the auxiliary device is composed of two semi-circular arc short columns, short column splicing plates, circular arc steel plates, bolts, and rubber gaskets, and two semi-circular arc short columns are connected by short column splicing plates and bolts.
  • a short round column the round short column is disassembled after the truss support is completed. After removing the bolts, a semi-circular arc short column on the side of the sliding direction can be directly removed. The truss can slide directly without jacking up.
  • the round short column The top of the steel plate is a circular arc steel plate, and the circular arc steel plate is connected with the circular short column by welding, and the top of the circular arc steel plate is fixed with a rubber gasket.
  • the truss can slide directly without jacking up, and the other short column does not affect the sliding and does not need to be disassembled.
  • the length of the short post splicing plate of the disassembled part is greater than the length of the short post splicing plate of the non-disassembled part.
  • the auxiliary device can reduce the calculated length of the support structure and improve its stability, while reducing the amount of steel used in the column and the support structure.
  • the round stub column is disassembled after the truss support is completed. After the bolts are removed, a semi-circular arc stub column on one side of the sliding direction can be directly removed. After the stub column is removed, the truss does not use jack The jacking can slide directly, the operation is simple and the construction is convenient. At the same time, the rubber gasket can effectively protect the surface of the truss during construction, and can avoid scratches and scratches on the surface of the truss during the installation and sliding process. Extrusion damage is beneficial to the protection of the anticorrosive layer on the surface of the truss.

Abstract

L'invention concerne un dispositif auxiliaire d'auto-retrait de support coulissant pour la construction d'une ferme à grande portée (A). Ledit dispositif comprend une courte colonne semi-circulaire côté non coulissant (3), une courte colonne semi-circulaire côté coulissant (4), une plaque de combinaison de courtes colonnes côté non coulissant (5), une plaque de combinaison de courtes colonnes côté coulissant (6), une plaque d'acier en forme d'arc (2), un boulon (7), et un espaceur en caoutchouc (1). Des trous sont agencés sur la plaque de combinaison de courtes colonnes côté non coulissant (5) et la plaque de combinaison de courtes colonnes côté coulissant (6). La courte colonne semi-circulaire côté non coulissant (3) et la courte colonne semi-circulaire côté coulissant (4) sont reliées l'une à l'autre au moyen du boulon (7) de manière à former une colonne courte circulaire. La plaque d'acier en forme d'arc (2) est soudée au sommet de la courte colonne circulaire. L'espaceur en caoutchouc (1) est fixé à la partie supérieure de la plaque en acier en forme d'arc (2). Après avoir terminé la fonction de support de la ferme, la courte colonne circulaire est retirée. Une fois le boulon (7) retiré, une courte colonne semi-circulaire (3) sur le côté coulissant est directement retirée, de telle sorte que le ferme (A) peut coulisser directement sans être soulevé par un vérin.
