Abstract
The utility model discloses a connecting piece for steel construction, including base, interior pole and hollow overcoat, the overcoat is fixed on the base, be provided with the skewed tooth on the inner wall of overcoat, be provided with corresponding engaging tooth on the interior pole, the engaging tooth is passed through to the one end of interior pole and the skewed tooth is connected in the overcoat, the other end and the steel structural member of interior pole are connected. The utility model discloses the steadiness of being connected between pole and the overcoat in can improving, and then improve the steadiness of whole steel construction connection.
Description
Technical field
The utility model relates to steel structure connection technical field, particularly relates to a kind of connector for steel work.
Background technology
Structural steelwork is made as main structure with steel, is one of main building construction types.Steel work is one of form of structure more common in modern construction engineering.The feature of steel is that intensity is high, from heavy and light, integral rigidity is good, deformability is strong, thus for building large span and superelevation, extra-duty building is suitable especially; Material homogeneity and isotropism good, belong to perfect elastic body, meet the basic assumption of common engineering mechanics most.Material plasticity, good toughness, can have larger distortion, can bear dynamic loading well.Construction period is short, and its industrialization degree is high, can carry out the high Virtual production of mechanization degree.Machining accuracy is high, efficiency is high, good leak tightness, therefore can be used for building gas tank, oil tank and transformer etc.But in actual application, connection between the component of steel work generally adopts 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, need to connect the preceding paragraph and carry out welding and lengthen, not only increase difficulty of construction, also reduce efficiency, and then affect attractive in appearance.
In order to solve the problems of the technologies described above, in prior art, propose following technology:
As China Patent No. " 201320145882.1 " to disclose a kind of scalable connector of construction steel structure on August 7th, 2013, its technical scheme is that described scalable connector comprises a base, described base is fixedly installed the overcoat of a hollow, the termination of described overcoat has inwardly protruded chuck, arrange in described overcoat one with the interior bar of described chuck dimensional fits, the length of described interior bar is greater 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 because the end of interior bar is connected with other steel structure member, and fix by means of only positioning element between interior bar in this patent and overcoat, a place is only had to support fixed point between the two, this just causes interior bar easily to rock, and then affect the steadiness of whole steel structure connection, in addition, the connector of this structure also also exists the slow shortcoming of governing speed.
Summary of the invention
The purpose of this utility model is to solve the above-mentioned problems in the prior art, and provide a kind of connector for steel work, the utility model can improve interior bar and the steadiness be connected between overcoat, and then improves the steadiness of whole steel structure connection.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of connector for steel work, it is characterized in that: the overcoat comprising base, interior bar and hollow, described overcoat is fixed on base, the inwall of described overcoat is provided with helical teeth, described interior bar is provided with corresponding engaging tooth, one end of described interior bar is connected in overcoat by engaging tooth and helical teeth, and the other end of described interior bar is connected with steel structure member.
Described interior bar is provided with adjustment scale.
Be provided with spring in described overcoat, one end of described spring is fixed on base, and the other end is fixed on interior bar.
Employing the utility model has the advantage of:
One, the interior bar in the utility model and overcoat are linked together by engaging tooth and helical teeth, this structure can either regulate the length of interior bar in overcoat, the contact area between interior bar and overcoat can be increased again, and then improve interior bar and the steadiness be connected between overcoat, and improve the steadiness of whole steel structure connection.In addition, the structure that engaging tooth and helical teeth coordinate, can lock interior bar, prevent interior bar from extracting in overcoat, be conducive to the steadiness improving whole connector further.
Two, the interior bar in the utility model is provided with scale, is convenient to by scale the length that people regulate whole connector operationally to need exactly, be conducive to improving efficiency of construction.
Three, the spring that the utility model is arranged in overcoat can internally play a supportive role by bar, people need use certain external force could regulate in overcoat in bar, people's maloperation can be avoided and cause whole connector not use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Be labeled as in figure: 1, base, 2, interior bar, 3, overcoat, 4, helical teeth, 5, engaging tooth, 6, scale, 7, spring.
Detailed description of the invention
A kind of connector for steel work, comprise base 1, the overcoat 3 of interior bar 2 and hollow, described base 1 is fixedly connected on steel work body, the overcoat 3 of described hollow is fixed on base 1, the inwall of described overcoat 3 is provided with helical teeth 4, described interior bar 2 is provided with corresponding engaging tooth 5, described helical teeth 4 tilts to base 1 direction, described engaging tooth 5 is contrary with the incline direction of helical teeth 4, one end of described interior bar 2 is connected in overcoat 3 by engaging tooth 5 and helical teeth 4, interior bar 2 coordinates by engaging tooth 5 degree of depth regulating it in overcoat 3 with helical teeth 4, the other end of described interior bar 2 is connected with steel structure member.
In the utility model, described engaging tooth 5 and helical teeth 4 are made by elastomeric material or steel, and have certain elasticity.
In the utility model, described interior bar 2 is provided with adjustment scale 6, described scale 6 is arranged from interior bar 2 and the junction of steel structure member.
In the utility model, be provided with spring 7 in described overcoat 3, one end of described spring 7 is fixed on base 1, and the other end is fixed on and is positioned on bar 2 end of overcoat 3, spring 7 has certain supporting role to interior bar 2, avoids people to cause whole connector to damage because arbitrarily regulating interior bar 2.
The utility model in use, the end of interior bar 2 is fixed on the end of overcoat 3 by engaging tooth 5 and helical teeth 4, now the length of whole connector is the longest, the length needing to regulate can be measured according to the scale 6 on interior bar 2, then indicate by scale 6, internal bar 2 applies external force, until external force is greater than the elastic force of spring 7, now interior bar 2 is to the motion of base 1 direction, until interior bar 2 is adjusted to scale 6 place of needs.
