Description

Node assembly of space net rack

Technical Field

The utility model relates to a large-scale public building space rack especially relates to a node subassembly of space rack.

Background

Under current public building design trend influences, china's large-scale public building is more and more, and large-span, high public space also increases thereupon, and the large-span space of the overwhelming majority all adopts space lattice framed structure, lattice framed structure's particularity, and pulling force down can not be born to its pull rod and vaulting pole, can't regard as the rooting point of decorating the furred ceiling, only the ball node can the atress, and lattice framed structure face decoration fire protection coating, and welding rooting can destroy lattice framed structure's fire protection coating, causes huge potential safety hazard.

At present, when net rack balls are used as nodes for connection, a buried plate is arranged behind the net rack balls, and a conversion layer is arranged below the net rack balls. The existing embedded plate fixes the peripheral hole sites, a special hoop is used for vertical cross binding, the bottom of the hoop is inserted into the hole sites and is screwed down by a nut, and a support rod connected with the upper part of a net rack ball changes along with the trend of the net rack structure, and the support rod connected with the upper part is not invariable, so that the defects of the following two points exist.

One is as follows: the existing embedded plate connection mode is relatively rigid and inflexible, and the fixed hole position cannot be correspondingly adjusted along with the actual change, so that the anchor ear cannot achieve the expected effect;

the second step is as follows: the buried plate has a flat surface, and is poor in stability, easy to loosen and slip when being in contact with a smooth spherical surface, so that great influence is caused on engineering, and great potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's weak point, provide a connected mode is nimble and accurate stable node subassembly of space rack.

The utility model provides a node component of the space net rack, which comprises a net rack ball, a buried plate and a hoop; the middle part of the embedded plate is provided with a round hole, the periphery of the embedded plate is provided with a circle of positioning holes which are arranged in an annular array relative to the round hole, and the net rack ball is embedded into the round hole and is fastened through a hoop penetrating through the positioning holes.

In order to further improve the stability, the buried plate is a rectangular plate, and the round hole is positioned at the geometric center of the buried plate.

In order to reduce the dead weight and ensure the installation flexibility, the positioning holes are round holes, and the included angle between every two adjacent round holes is 11.25 degrees.

Preferably, the hoops are in a pair, and the pair of hoops are vertically arranged and tightly hold the outside of the net rack ball.

In order to improve the holding effect, the staple bolt for match in the U type staple bolt of rack ball is equipped with the circular arc gap bridge with staple bolt arc top department to the outside in the staple bolt.

Preferably, the hoop is wrapped with an anti-slip sleeve.

The utility model discloses open the centre bore on burying the board to punch with the form winding of array around the centre bore, fasten the staple bolt in the net rack ball embedding centre bore during the installation through the staple bolt, the staple bolt can select different hole sites according to the operating mode. The setting up of centre bore can improve the location precision of rack ball on the one hand, reduce the error to can improve the stability of connecting, on the other hand can reduce the dead weight, the hoist and mount of being convenient for. The winding is punched and can be further reduced the dead weight, also can increase the installation position, can be applicable to different operating modes, ensures that the staple bolt can form good alternately and encircle, increases mounting means's flexibility ratio.

Detailed Description

As shown in fig. 1 and 2, the node assembly of the space net rack disclosed by the embodiment comprises a net rack ball 1, a buried plate 2 and an anchor ear 3.

The embedded plate 2 is a rectangular plate, a round hole 21 matched with the net rack ball is arranged at the geometric center of the embedded plate, during actual construction, the spherical bottom of the net rack ball is embedded into the round hole, the connection between the embedded plate and the net rack ball is stabilized, the connection stability is improved, and the error of the embedded plate connection is reduced because the round hole is arranged in the center of the embedded plate; and be equipped with the locating hole 22 that the round is annular array and arranges about the round hole around burying the board, the contained angle between two adjacent locating holes is 11.25, makes the staple bolt can follow different angle installations, guarantees to realize under each operating mode that a pair of staple bolt is installed perpendicularly, forms good alternately and encircles, ensures the reliability of connecting and has guaranteed the flexibility ratio of installation again, makes the ligature effect reach expected value.

Staple bolt 3 is U type staple bolt, sets up in pairs, and a pair of staple bolt mutually perpendicular when the installation all holds tightly outside the net rack ball to with be equipped with circular arc gap bridge 31 in the staple bolt arc top department to the outside in the staple bolt so that improve the connection effect, and further guarantee to connect reliably at the outer cladding antiskid cover 32 of staple bolt.

During actual construction, open a great round hole in the center of burying the board, the size is decided according to burying board size, specification model, and this hole will hold the face of rack ball bottom, and bottom sphere embedding round hole, greatly increased its steadiness, because the round hole is opened in burying the board is positive, so has just also reduced the error of burying the board connection. The positioning holes with the diameter of 15mm are formed in the embedded plate, holes are formed in a winding mode in an array mode, the distance and the angle are set according to the size and the specification of the embedded plate, the distance and the included angle between each hole and the corresponding hole are kept consistent, and therefore the connecting mode of the hoop bottom is flexible and changeable, and the binding effect of the hoop bottom can reach the expected value. And the round hole in the center and the round positioning hole are arranged to be beneficial to reducing the weight of the embedded plate, so that the burden of the suspended ceiling in the current large space is reduced.

During connection, the spherical bottom of the net rack ball is embedded into the round hole of the embedded plate, and the connection between the embedded plate and the net rack ball is stabilized; and the position of the U-shaped hoop is changed according to the position of the stay bar at the upper part of the on-site net rack ball, so that the U-shaped hoop is firmly attached to the net rack ball to form good cross surrounding, and then the bottom of the U-shaped hoop is inserted into the reserved hole of the buried plate to achieve the stabilizing effect.
