Abstract
The utility model relates to a portal-frame zocle without the shear key, which comprises a fang bolt pre-buried in the cement mortar base. The portal-frame column is fixed on the cement mortar base through a zocle soleplate connected fixed to the bottom and the fang bolt; the zocle soleplate is provided with a fang bolt hole, which is sleeved in the fang blot and then fixed by double nuts; the fang bolt hole at the zocle soleplate is welded with a thickened gasket which is sleeved with the fang bolt in the fang bolt hole and then fixed by double nuts. Thus, the utility model has the advantages of simple and reasonable structure, convenient construction and installation, fast construction speed, low engineering cost, good and safe project quality, and ability to meet design standards and requirements of steel-structure constructions.
Description
Technical field
The utility model relates to a kind of fixed connection apparatus of building suspension column of lightweight steel construction, belong to construction steel structure suspension column device.
Background technology
At present, the suspension column of individual layer gate-type light-weight steel cage structure is mostly by being embedded in the crab-bolt in the cement mortar basis in advance, with suspension column with non-ly rigidly connecting form, being that hinged securement is on the basis, consider that in design process the suffered power of suspension column comprises shearing and axle power, wherein crab-bolt is being born pulling force, promptly axle power generally also must be provided with shear key for shearing and be guaranteed on the basis.Since shear key requirement preformed groove in the basis is set, treat to remake back-grouting and maintenance behind the door pillar installation in position, increase difficulty so not only for construction, and directly have influence on workmanship sometimes; Not only influence construction speed, but also can increase construction costs.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of shear key that need not be provided with can satisfy the portal frame suspension column of not establishing shear key that building safety is produced needs.It comprises the crab-bolt that is embedded in advance in the cement mortar basis, and the portal frame post is fixed on the cement mortar basis by suspension column base plate and the crab-bolt that the bottom is connected, and offers anchor hole on the suspension column base plate, wears after the crab-bolt fastening with double nut in it.
Be welded with the thickening pad on the anchor hole of described suspension column base plate, in anchor hole, wear into crab-bolt fastening again with double nut.
The utility model compared with prior art, have simple and reasonable for structure, construction install convenience, construction speed is fast, at the bottom of the construction costs, good engineering quality, safety can satisfy characteristics such as the design specifications of steel building and requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the figure, the utility model includes four crab-bolts 2 that are embedded in advance in the cement mortar basis 1, the bottom weldering of portal frame post is shaped on a base plate 3, this base plate 3 is provided with four anchor hole accordingly, and the top weldering of this anchor hole is shaped on thickening pad 4.After base plate is positioned on the basis 1, anchor hole is inserted in crab-bolt 2 respectively, fastening locking with double nut 5, thus the portal frame post is fixed on the basis 1.The utility model makes suspension column one side anchor bolt tension and the corresponding increase of base plate 3 counter-forces of opposite side because the portal frame post has moment of flexure, the also corresponding increase of the frictional force of suspension column thereupon, the effect that produces shearing resistance.The utility model is not established former suspension column shear key by structural appropriate design, and the comprehensive benefit of acquisition has: the phenomenon of doing over again of groove aspect is stayed on the basis that 1, can avoid fully often occurring in the construction of foundation construction and Steel Structure Installation; 2, when avoiding doing over again, effectively guarantee the workmanship of basic aspect; 3, reduce difficulty of construction effectively, accelerated construction speed; 4, obviously reduce steel using amount, reduced construction costs.
Claims (2)
1, do not establish the portal frame suspension column of shear key, it comprises the crab-bolt that is embedded in advance in the cement mortar basis, the portal frame post is fixed on the cement mortar basis by suspension column base plate and the crab-bolt that the bottom is connected, it is characterized in that offering anchor hole on the described suspension column base plate (3), wear into crab-bolt (2) back fastening in it with double nut (5).
2, the portal frame suspension column of not establishing shear key according to claim 1 is characterized in that being welded with thickening pad (4) on the anchor hole of described suspension column base plate (3), wears into crab-bolt (2) fastening with double nut (5) again in anchor hole.
