Description
Technical field
The present invention relates to a kind of steel building installation auxiliary devices, and in particular to a kind of steel building with being tightly connected in advance
Device belongs to steel building technical field.
Background technique
In order to guarantee the stability of steel building, between the fashioned iron of steel building, reinforcement structure can be generally installed additional
Zhang Zhang's taut band of stability, the tensioner band are generally steel band, and the both ends of steel band are fixed on position by fastener
On steel construction profile, the tensioner band generally used in this kind of steel construction, due to generally without expanding force, rising during installation
It is tight ineffective, in order to solve these problems, it is provided with spring on some tensioner parts, still, this kind of tensioner part is in installation process
The middle pulling force for needing to overcome spring brings certain difficulty to installation, and some tensioning devices in addition are on tensioner steel band
The bending section of elasticity is produced, still, the bending section of the elasticity, which exists, is easy to damage steel band, and it uses be easy fatigue fracture for a long time,
There are some potential safety problemss, and need frequent maintenance, and there is also defects inconvenient for use.
Summary of the invention
It is an object of the invention to: for existing steel building with drawbacks described above present in attachment device is pre-tightened, originally
Invention provides a kind of novel steel building preload attachment device, and existing steel building is overcome to pre-tighten attachment device institute
Existing drawbacks described above.
The present invention realizes that technical solution used by above-mentioned purpose is: a kind of steel building is tightly connected dress with pre-
It sets, it includes sleeve (1), it is characterized in that: blind hole (15) are formed in the sleeve (1), opening with the sleeve (1)
Mouth end is formed with the open slot (14) communicated with blind hole (15) along generatrix direction, further: the length of the open slot (14)
Lug is symmetrically formed with the sleeve (1) of open slot (14) two sides at least more than the one third of blind hole (15) depth
(8), bolt (9) are connected between two lugs (8), are provided with pull rod (3) in the blind hole (15) of sleeve (1), it is described
The end that pull rod (3) is in blind hole is fixedly connected with flange (4), spring (6) is socketed on the round bar of pull rod (3), in bullet
The round bar portion of the pull rod (3) of spring (6) outer end is successively socketed with washer (5) and screwed pipe (2), the outer circle of the screwed pipe (2)
On be formed with external screw thread, and blind hole (15) the opening position of sleeve (1) is mounted in a manner of being threadedly engaged, in the outer of pull rod (3)
End is fixedly installed with the connector (10) of U-shaped with nut (11), and the crotch two sides of opening of connector (10) are provided with pin shaft (12),
The bottom outer end of sleeve (1) is formed with boss (7), is formed with connecting hole (13) on the boss (7).
Application method of the invention is: by the connecting hole (13) in the present apparatus and the connector (10) of U-shaped respectively with
The steel band or wirerope of suitable length are connected and fixed, by the other end of the steel band or wirerope respectively with two steel constructions
Part is connected and fixed, release bolt (9), adjusts the depth that screwed pipe (2) enter blind hole (15), even if spring (6) generates centainly
Elastic force, the elastic force will act on the steel band or wirerope, then tighten bolt (9), lock the outer circle of screwed pipe (3)
Extremely.
The utility model has the advantages that the present invention has application method it can be seen from the principle of the present invention main view and the course of work
As can be seen that the present invention has easy to use, installation is simple, pretightning force is adjustable, safe and reliable advantage.
