Abstract
The utility model discloses a secondary telescoping connection spare for steel construction, including base, connecting seat, interior pole and hollow overcoat, the connecting seat is fixed on the base, the overcoat thread tightening is on the connecting seat, the threaded one end of interior pole is fixed in the overcoat, and the other end is connected with steel structural member. The utility model discloses length that can the secondary regulation connecting piece to can the increase substantially length of whole connecting piece makes it be applicable to various operating modes.
Description
Technical field
This utility model relates to steel structure connection technical field, particularly relates to a kind of secondary telescopic connection for steel construction.
Background technology
Structural steelwork is to be made as main structure with steel, is one of main building construction types. Steel construction is one of version more common in modern construction engineering. The feature of steel be intensity high, from heavy and light, integral rigidity is good, deformability is strong, therefore it is particularly suitable to be used for building large span and superelevation, extra-duty building; Material homogeneity and isotropism are good, belong to perfect elastic body, meet the basic assumption of common engineering mechanics most. Material plasticity, good toughness, can have bigger deformation, can bear dynamic load well. Construction period is short, and its industrialization degree is high, can carry out the Virtual production that mechanization degree is high. Machining accuracy is high, efficiency is high, good leak tightness, therefore can be used for building gas tank, oil tank and transformator etc. But in actual application, connection between the component of steel construction is generally adopted the modes such as welding or bolt connection, some exposes part and adopts welding or bolt mode to connect, there is inaesthetic shortcoming, particularly run into component length inadequate time, it is necessary to connect the preceding paragraph carry out welding lengthen, not only increase difficulty of construction, also reduce labor efficiency, and then affect attractive in appearance.
In order to solve above-mentioned technical problem, prior art proposes following technology:
As China Patent No. " 201320145882.1 " discloses the scalable connector of a kind of construction steel structure on August 7th, 2013, its technical scheme is that described scalable connector includes a base, described base is fixedly installed the overcoat of a hollow, the termination of described overcoat has inwardly protruded chuck, described overcoat arranges the interior bar of and described chuck dimensional fits, the length of described interior bar is more than described overcoat, one end that described interior bar is positioned at described jacket internal has a boss, the external dimensions of described boss coordinates with the inside dimension of described overcoat, described interior bar can slide relative to described overcoat. but this patent is in actual application, interior bar can only stretch in overcoat, is equivalent to once to stretch, although can use in major part operating mode, but need the special operation condition of longer connector still can not use at some, there is the defect using narrow range.
Summary of the invention
The purpose of this utility model is in that to solve the above-mentioned problems in the prior art, a kind of secondary telescopic connection for steel construction is provided, this utility model can the length of Secondary Control connector such that it is able to the length of the whole connector that increases substantially so that it is suitable in various operating modes.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of secondary telescopic connection for steel construction, it is characterized in that: include base, connect the overcoat of seat, interior bar and hollow, described connection seat is fixed on base, described sleeve thread is fixed on connection seat, the threaded one end of described interior bar is fixed in overcoat, and the other end is connected with steel structure member.
Described connection seat is circular, and the circular middle part connecting seat offers screwed hole, and described overcoat is fixed on connection seat by screwed hole.
Being provided with the external diameter spacing preiection more than outer casing internal diameter on described interior bar, this spacing preiection is near the link of interior bar Yu steel structure member.
Employing the utility model has the advantage of:
One, in this utility model, interior bar is threadedly secured in overcoat, can carry out the length of adjusting connector by regulating interior bar position in overcoat, and such regulative mode is Primary regulation; When the length after Primary regulation still can not meet construction needs, can again through regulating overcoat with the position being connected between seat to realize the Secondary Control of connector length; So, by the length of twice adjusting connector, it becomes possible to the length of the whole connector that increases substantially so that it is suitable in various operating modes. Additionally, compared with prior art, overcoat respectively with interior bar and be connected the threaded structure of seat and can also increase the contact area of each parts, and then interior bar and overcoat, interior bar and the steadiness being connected between seat to connect can be improved, and improve the steadiness of whole steel structure connection.
Two, in this utility model, overcoat is fixed on the structure connected on seat by screwed hole, not only improves and improves the outer steadiness being enclosed within and connecting on seat, is conducive to again the length of quick adjusting connector.
Three, in this utility model, by spacing preiection it can be avoided that interior bar is excessively entering into overcoat and causes that overcoat deforms.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Figure is labeled as: 1, base, 2, interior bar, 3, overcoat, 4, connect seat, 5, protruding.
Detailed description of the invention
A kind of secondary telescopic connection for steel construction, including base 1, the overcoat 3 connecting seat 4, interior bar 2 and hollow, described base 1 is fixedly connected on steel construction body, described connection seat 4 is fixed on base 1, described connection seat 4 is circular, and the circular middle part connecting seat 4 offers screwed hole, and described overcoat 3 is fixed on connection seat 4 by screwed hole, the threaded one end of described interior bar 2 is fixed in overcoat 3, and the other end is connected with steel structure member. Being provided with the external diameter spacing preiection 5 more than overcoat 3 internal diameter on described interior bar 2, this spacing preiection 5 is near the link of interior bar 2 with steel structure member.
This utility model is in use, it is adjusted to Primary regulation between overcoat 3 and interior bar 2, overcoat 3 is adjusted to Secondary Control with being connected between seat 4, just can be applicable to the special operation condition of longer connector by Secondary Control, thus meeting the different needs of construction.
