Problems solved by technology

The beam spanning distance of the current column-beam system is relatively long, and the longest length of the beam is 12m, which not only makes the use of the beam large, but also has a certain impact on construction operations such as foundation pit excavation due to the long spanning distance of the beam. It is not conducive to construction operations such as foundation pit excavation

Embodiment 1

[0029] Embodiment 1: as figure 1 , figure 2 As shown, a single-column-joist system in a building includes a column 1 . Two brackets 2 are arranged on the upper part of the column. The bracket part of this embodiment is connected with the upright post through bolts. The two bracket parts are located at the same height, and the two bracket parts are symmetrically distributed on opposite sides of the column. A horizontal beam 3 is respectively arranged on the two bracket parts. The beam is located above the bracket piece. The beam and the bracket are connected by bolts. The crossbeam is made of H-shaped steel, and the wing plates of the H-shaped steel constituting the crossbeam are arranged horizontally. The beams on the two bracket parts are parallel to each other. The distance between any end of each beam and the column is the same.

[0030] Two ends of the crossbeam are respectively provided with a top tight limit member 4 . The top tight limit member is located abo...

Embodiment 2

[0033] Embodiment 2, the remaining structure of this embodiment is with reference to embodiment 1, and its difference is:

[0034] Such as Figure 5 As shown, a joist system supporting a single column in a building also includes an installation sleeve 6 that is sleeved on the column and can slide along the column. The bracket part 2 of this embodiment is arranged on the installation sleeve. The bracket part and the installation sleeve body are welded as a whole.

[0035] Such as Figure 5 , Figure 6 , Figure 7 As shown, there are installation notches 8 on the lower end surface of the installation sleeve. In this embodiment, there are two installation notches, and the two installation notches are symmetrically distributed on opposite sides of the column. Each installation notch is provided with a one-way automatic fastening anti-falling-off mechanism 7 . The one-way automatic fastening anti-falling mechanism includes an eccentric wheel 72 rotatably arranged in the insta...

Abstract

The invention discloses a Single-pillar joist system for intra-building supporting and is intended to provide a single-pillar joist system for intra-building supporting which enables shortened span of cross beams and narrowed influence range for a foundation pit construction face and uses less cross beams. The system comprises a pillar, the upper portion of the pillar is provided with two brackets at same height, the two brackets are distributed on two opposite sides of the pillar and each provided with a horizontally arranged cross beam, and the cross beams on the two brackets are parallel to each other.

Description

technical field [0001] The invention relates to the field of building foundation pits, in particular to a single-column joist system for supporting buildings. Background technique [0002] In the construction of building foundation pits, it is often necessary to erect internal supports (horizontal support beams) to support the foundation pit, and then after excavating the bottom floor, construct the bottom floor, side walls and roof of the building to complete the construction of the foundation pit. When the building foundation pit adopts the steel internal support, it is usually necessary to use the column beam system as the vertical load-bearing and restraint member of the steel internal support, and the steel internal support is erected horizontally on the beam of the column beam system. [0003] Such as Figure 8 As shown, the traditional column-beam system supported by section steel adopts a single beam 3 with columns 1 at both ends, and brackets 2 are arranged on the t...
