Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame 11, in particular a steel structure, in which 113 parts I are connected to one piece of steel, and is formed as a circulation vibrator, the end of which converges into the joint 1 is connected to each joint 1 element by screw coupling means arranged in the support bra 1 of the vibrator (J). It is related to structures.

Known joins 1 to 1 of this type have part +2 tension J

It has the advantage of being transmitted to the heart of the Indian union. The end of the working circulation vibrator ends in a trapezoidal metal member with an axial hole.
This circle 841 unit 1 - (The hole 1 ~ into which the head of the pipe is inserted is installed at the end of the pipe.) The child enters into the hole 1- and can pass through the hole (and protrude to the outside). (Yo, IT] 8

The join 1 element described above has a number of drawbacks.

[Additional] - There are many covered metal parts, and the structure is complicated.

Circulating Vibrator Circle 6.11 Trapezoidal Metal Fittings 1) The 2 parts are weak points (the strength of the Circulating Vibrator cannot be fully utilized. When the cross-section of the bolt core overlaps the floating link, the hole 1 itself is subjected to notch tension and no rigid connection is formed between the member and the joint element.
It forms a type of joint-like connection. When designing a component, the total length from the front end of the bolt to the screw must be 4f. The rigidity of the frame is low.

When installing the Soufurifu small 1-hole, make sure to assemble it into the pipe and make a hole for water use. Locally reduces the strength of the pipe cross section.The inner wall of the pipe is not susceptible to corrosion, and it is almost impossible to cover the pipe to protect it from the effects of heat in the event of a fire. Therefore, fireproof illumination is insufficient for halls and hangars where a large number of people gather. A rigid joint with a weak end to which three or more members are connected.
The object of the present invention is to provide a simple join 1 to C1 which does not have the above-mentioned drawbacks and which is made of a clay culm. Join 1 of the type mentioned in the beginning - join a
In 3, the gist of the invention is that the end of the circulation pipe has an external thread with a root diameter at least equal to the outer diameter of the circulation vibrator, reducing its cross-sectional area and deflection strength;
A union nut slidable or rotatable on the circulation pipe can be moved by its internal thread on said external thread and further

Tarari. The hollow space communicating with the joint 1 through the element is filled with a liquid such as water, an anticorrosive agent and, if desired, an antifreeze agent are added, and this liquid is heated,
It can be used for cooling and/or extinguishing in case of fire, or also for storage of solar energy, etc.

In a preferred embodiment of the join 1 to element of the present invention,
The 21-ion nut moves the corresponding outer thread of the joint element with the previous part of its inner thread. In the case of liquid-filled structures, a sealing ring, which may act as a surface reduction screen, is placed between the end of the circulation vibrator and the externally threaded portion of the joint element to prevent circulation. Vibrator formed by vibrator
The flow in the joint can be adjusted by this sealing ring. In another and most preferred embodiment of the joint l-joint according to the invention, the joint l is connected to the union lug with its external threads. The internal threads of the inner and outer joints 1- and 1- are arranged concentrically with the same pitch. The screws J, υ and external screws are fixed in the same part in the longitudinal direction, and the circulation vibe is connected to the joint 1 that protrudes inside. Ru.

It is practical to prepare a sleeve with a spiral shape and a wavy shape. It is recommended to provide a tension output ring at the rear end of the joint element. (JE+-Tangential, 2)
- Seal the inner thread of the onion nut and the circulation vibrator via the inner seal ring.

The union nut 1-, which rightly covers the inner thread J5 and the outer thread along the same portion in the longitudinal direction, can also be formed as a helix. In the case of a liquid-filled truss structure, it is possible to fill the area between the lazen-shaped windings in the region 1, where the circulation vibrator protrudes into the joint element.

Union nuts with internal and external threads mounted on the same lengthwise section can also be formed with an embedded helix or a sleeve with a 21 or I slot. , in its cross section, there are two divided lines Cd of different shapes.

The lifting platform of the liquid-filled structure, the joint 1~element, is hollow and extends along the adjacent circulation vibrator slot 111. Open joint element (
It is practical to make the diameter of the pipe at least equal to the inner diameter of the circulation vibrator. The external threads can be formed on the end of the circulation vibrator by plastic deformation processes such as pressing, forging and/or rolling.

However, the external screw is a thick forged shield.
It can also be provided by cutting on the wall at the end of the vibrator.

Alternatively, the external thread can be welded to the end of the circulating vibrator by build-up welding or by welding 5' (1, 1, 1, 1, 1, 1, 2, 2, 3, 4, 5', 5', 1, 1, 1, 1, 2, 2, 3, 3, 4, 4, 5, 4, 5, 4, 5, 4, 5, 4, 5, 4, 5, 4, 5, 4, 4, 4, 4, 4, 4, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 3, 4, 4, 4, 4, 4, 4, 4, 3, 4, , ) to be able to - l) to be able to do it.

The structure surrounding the joint joint according to the present invention is conveniently filled with a liquid, such as water, flowing through the joint element and connected to a liquid ring means.

Join 1 - The element and/or the circulation vibrator is equipped with a balloon I (for example, in the event of a fire, it responds to pressure and temperature higher than a predetermined value) and listens to this,
C/linknosis T to fire source or structure depending on each
It is possible to carry out a water spray similar to a vacuum cleaner and to cool the pipe wall by the flow thus created in the vibrator.

A detailed description of the invention will now be described with reference to the accompanying drawings, in which aspects of the joint connection according to the invention and the structure constructed from the joints are shown.

FIG. 1 shows in a simplified representation a structure in the form of a typical two-tier space truss structure, which is comprised of members consisting of a di-ind element 1 and a circulation vibrator 2. FIG.
The joint element 1 and the circulation vibe 2 form a liquid flow system in their hollow parts. This liquid system is installed in the corner of the space truss structure.
and position ii':i'? at the center of the space truss structure. The reflux line 4 to -C1 is connected to the liquid circulation means.

A liquid container 5, a three-way valve and a pump 7 are used in this liquid circulation means.A three-way valve 6 is connected to a heat exchanger 8 which serves as a heater, cooler or for solar energy recovery. Fluid can be supplied through a bypass line leading to pump 7. 1. If this heat exchanger is used as a heater, pump 7
The operation is 1'1 by heatcon 1~roll. In the event of a fire, a signal from the fire alarm system or switch to the valve D-1 will also listen to one of the hot water or pressure-operated valves in the network if there is a shortage of liquid. to operate the pump. Losses in the liquid system are routed from the local water supply line to the control valve 9 depending on the level of the liquid container 5.
After leaving, I decided to replenish J-Koto. As liquid it is possible to use water to which anticorrosion and antifreeze agents have been added. Figure 2 shows join 1, which is marked 1 in Figure 1.

The external thread 10 in FIG. 3 is formed by pressing, and the external thread in FIG. 4 is formed by rolling or cutting the forged end of the forged a5 and barb. As shown in FIG. 5, the external screw 101 is formed by overlay welding to the bi 127 and is an IC type. According to FIG. 6, the external screw] O is a helix with an irregular cross section of 1 mm at the end of the circulation vibrator 2. For example, it is formed by resistance pressure welding. In either case, the root diameter d of the external thread 10 is at least equal to the outer diameter of the circulation vibrator 2, and the cross-sectional area of the vibrator is not reduced.

FIG. 7 shows the joint connection in an enlarged cross-section.
