Description

Steel construction rack convenient to adjust

Technical Field

The utility model relates to the technical field of steel structures, in particular to a steel structure net rack convenient to adjust.

Background

A space structure formed by connecting a plurality of rod pieces through nodes according to a certain grid form; the device has the advantages of small space stress, light weight, high rigidity, good earthquake resistance and the like; the roof can be used as a roof of buildings such as gymnasiums, movie theaters, exhibition halls, waiting halls, stadium stand awnings, hangars, bidirectional large-column-distance workshops and the like.

At present, a front loading method, a bulk loading method and the like are mostly adopted during installation, and when the bulk loading method is adopted for installation, a crane is needed for hoisting, and manual connection and installation are carried out on a net rack; however, in the process of installation by the bulk method, because the screw hole angle of the spherical bolt is fixed, the angle needs to be aligned when the connecting rod is installed to ensure that the screw rod is screwed into the screw hole, and the screw rod can be screwed into the screw hole through a large force even if the angle is slightly inclined when the connecting rod is initially aligned, so that the contact part of the connecting head of the connecting rod and the screw hole is abraded, and the connection stability of the rear section can be influenced.

Preferably, a hexagonal nut is fixed on the screw rod close to the connecting rod, and one end of the screw rod far away from the connecting rod is in threaded connection with the screw hole.

Preferably, the connecting end of the screw hole is provided with an inclined groove.

Preferably, the screw rod is sleeved with a spring, and the spring is arranged between the limiting piece and the hexagonal nut.

Preferably, the limiting sliding groove is arranged in a cross shape.

(III) advantageous effects

Compared with the prior art, the utility model has the following beneficial effects:

1. this kind of novel be applied to steel construction rack convenient to adjust through setting up spacing spout and spacing piece, before screw rod and screw butt joint, earlier through spacing piece and spacing spout butt joint, guarantees to carry out threaded connection again with the screw when a horizontal direction with the screw, sets up like this and can guarantee can not produce the friction between screw rod and the screw and cause wearing and tearing.

2. This kind of novel be applied to steel construction rack convenient to adjust through setting up the chute at the screw link, can more conveniently dock screw rod and screw, simultaneously, sets up the spring between spacing piece and hexagon nut, is the pretightning force in order to increase the monolithic connection.

FIG. 1 is a schematic view of an overall structure of the present invention;

FIG. 2 is a schematic view of the expanded structure of the ball stud and the connecting rod of the present invention;

FIG. 3 is a schematic view of the structure of the ball screw bolt of the present invention after being connected with a connecting rod.

In the figure: 1. a ball bolt; 101. a screw hole; 102. a limiting chute; 103. a chute; 2. a connecting rod; 201. a screw; 202. a hexagonal nut; 203. a spring; 204. a limiting sheet.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-3, a steel structure net rack convenient to adjust comprises a spherical bolt 1, a screw hole 101 is formed in the spherical bolt 1, a limiting sliding groove 102 is formed in the outer wall of the connecting end of the screw hole 101, a connecting rod 2 is connected to the spherical bolt 1, a screw rod 201 is connected to the connecting end of the connecting rod 2 in a threaded manner, and a limiting piece 204 matched with the limiting sliding groove 102 is connected to the screw rod 201 in a threaded manner.

As shown in fig. 3, a hexagon nut 202 is fixed on the screw 201 close to the connecting rod 2, one end of the screw 201 far from the connecting rod 2 is in threaded connection with the screw hole 101, the connecting rod 2 is connected with the ball bolt 1 through the screw 201, and then the screw 201 is rotated through the hexagon nut 202.

As shown in fig. 2, the connecting end of the screw hole 101 is provided with an inclined groove 103, and when the screw 201 slides to the screw hole 101, the screw can be more easily butted with the screw hole 101 through the inclined groove 103.

As shown in fig. 2 and 3, a spring 203 is sleeved on the screw 201, the spring 203 is arranged between the limiting sheet 204 and the hexagonal nut 202, and the pre-tightening force can be increased by adding the spring 203.

As shown in fig. 2, the position-limiting sliding groove 102 is a cross-shaped arrangement, which is provided to initially slide the hole in four directions.

The working principle is as follows: when the device is used, when a net rack is used in bulk, a constructor slides the screw 201 to the screw hole 101 through the limiting sliding groove 102, then rotates the limiting piece 204 on the screw 201 to the limiting sliding groove 102, then clamps the limiting piece 204 into the limiting sliding groove 102, and at the moment, the connecting rod 2 and the spherical bolt 1 are in a vertical state, so that the screw 201 can be screwed into the screw hole 101 more conveniently, and the screw 201 cannot wear the screw hole 101 due to angle deflection.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
