Description

Basement dish knot frame double-groove steel joist structure with increased limiting side wall surface Technical Field The utility model relates to the technical field of engineering supporting beams, in particular to a basement plate buckle frame double-groove steel joist structure with an additional limiting side wall surface. Background The double channel steel joist is an important component in the support frame, the structure of the existing double channel steel joist is referred to as figure 5, wherein two connecting discs fixedly connected through a connecting rod 6 are arranged in the interval between two channel steel beams, jacking is connected to the two connecting discs through equal threads, and the jacking is used for supporting engineering loads. Although the double-groove steel joist is used as a support in the support frame, the material consumption of the support frame can be reduced, the relative position between the two connecting discs is determined through the connecting rod 6, the structure is increased, and the installation efficiency is reduced. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides a basement plate buckle frame double-groove steel joist structure with an increased limiting side wall surface, which solves the problem that the installation efficiency is reduced due to the fact that the existing double-groove steel joist is supported by using a connecting disc. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a basement dish knot frame double flute steel joist structure of spacing lateral wall increases, including two pole settings that set up in opposition, be fixed with two transverse setting's steel channel beams between two pole settings, be provided with two and fall U type collet on two steel channel beams, every falls U type collet and all includes the U template of open block in two steel channel beam both sides, the vertical sleeve that is equipped with in middle part of every U template, every sleeve internal thread connection has the screw thread post, every screw thread post top all with the jacking welding, it has the fossil fragments roof beam to support on two jacking, all be provided with the limit head on the both ends of fossil fragments roof beam. In this scheme, through the structure of the direct block of falling U type collet in double-channel girder steel both sides to when fossil fragments Liang Fang are on the collet, the screw thread post is difficult to rock, and the U template of falling U type collet is compared the connecting plate in the prior art and is additionally provided two lateral wall faces that can spacing, thereby more convenient fixed, simultaneously because be provided with the limit head on the fossil fragments roof beam, thereby the collet can be directly located the both ends of fossil fragments roof beam respectively, directly prescribe a limit to the interval between two falling U type collet through fossil fragments roof beam, has avoided the setting of connecting rod, has simplified the installation procedure, improves the efficiency of construction. Further, the two steel channel beams are U-shaped steel beams, and the two steel channel beams are horizontally arranged and open towards opposite directions. Further, a plurality of equidistantly distributed bolt holes are formed in each steel channel girder, and two steel channel girders are connected through a plurality of bolt holes. Further, bolts for connecting the two steel channel beams are arranged on two sides of each U-shaped plate. The bolts between the two steel channel beams not only play a role in connection, but also can limit the movement of the U-shaped plate. Further, each limiting head comprises two limiting plates which are vertically arranged at the end parts of the keel beams in a opposite mode, and a through groove used for the positioning bolt to pass through is formed in the middle of each limiting plate. The locating bolt and the limiting plate can prevent the keel beam from shaking on the jacking. The limiting plate with the through groove in the middle is less in material consumption compared with the limiting plate with the whole solid structure. Further, each limiting plate is a plate structure with a right trapezoid shape in front projection and an isosceles trapezoid shape in top projection. Top inclined surface and end of limit plate Further, connecting discs for supporting the steel channel beams are welded on the two vertical rods. Further, the length of fossil fragments roof beam is less than the interval between two pole setting, so set up the length of fossil fragments roof beam and avoid beam end and pole setting direct collision, reserve the deformation compensation space, improve the structural safety margin.
