Preferably, the locating body is provided with mortise holes at two sides of the bearing body, locking bodies are arranged in the mortise holes, and the bearing body is fixedly connected with the locking bodies at two sides through bolts and nuts.

Preferably, the lower end of the locking body is provided with a mortise III matched with the positioning body.

Preferably, the device further comprises a plurality of stress bodies, wherein the stress bodies are detachably connected with the upper ends of the bearing bodies through connecting assemblies.

Preferably, the connecting assembly comprises a connecting body and at least one positioning body, wherein the lower end of the connecting body is provided with a mortise IV matched with the bearing body, the upper end of the connecting body is provided with a mortise V matched with the positioning body, the upper end of the positioning body is provided with a containing groove matched with the stress body, and the lower end of the positioning body is provided with a mortise VI matched with the connecting body.

Preferably, the number of the positioning bodies is two, and the two positioning bodies are respectively positioned at two sides of the bearing body.

Preferably, the lower ends of the rest bearing bodies except the two foremost bearing bodies and the rearmost bearing bodies are respectively provided with a weight reduction groove.

Preferably, a plurality of clapboards are arranged between the two foremost bearing bodies, a plurality of clapboards are arranged between the two rearmost bearing bodies, and two ends of each clapboards are connected with corresponding bearing bodies through mortise and tenon joints.

The invention has the beneficial effects that: 1. this abandonment tradition frame roof beam needs welded mode, adopts novel mortise and tenon structure, and the installation degree of difficulty of greatly reduced frame roof beam, easy dismounting does not need electric welding, reduces manpower and materials.

2. Traditional girder erection in the market is poor in quality, and due to large flame cutting work and long-time high temperature, deformation and bending of original outsourcing steel plate girders of companies can occur. The novel tenon riveting structure is adopted in the girder, stability and bearing capacity are greatly improved, the girder can bear more than 100 tons of weight, and bending deformation cannot be generated under the high-temperature condition.

3. The novel mortise and tenon structure is adopted in the girder erection, the girder erection can be disassembled and assembled, the transportation is convenient, the transportation space is small, and the transportation cost is saved.

4. The traditional girder erection can not be changed after the girder erection is assembled, the girder erection can be temporarily adjusted according to the size of the field, the locating body and the bearing body with proper lengths are replaced or the locating body and the bearing body are cut to remove redundant parts, and the girder erection has good assembly flexibility.

5. Because the atress body and the locating body are direct with the material contact of being processed, when flame or laser cutting, directly cause the damage to it, so wear out very fast, through coupling assembling's design, compare with traditional with angle steel welded connection, can be with trading convenient, replacement cost is low.

6. The locating body all is equipped with the fourth of twelve earthly branches hole in the both sides of bearing body, all is equipped with the locking body in the fourth of twelve earthly branches hole, and the bearing body passes through the locking body fixed connection of bolt and nut and both sides, improves fixed fastness, prevents to loose to convenient assembling.

The features and advantages of the present invention will be described in detail by way of example with reference to the accompanying drawings.
