Example 1
Please refer to fig. 1, fig. 2 and fig. 3, in this embodiment 1, an overhanging type material table with a horizontal supporting system is provided, which includes a discharging platform body 1, an overhanging connecting beam 2, and a horizontal supporting system, where the overhanging connecting beam 2 is fixedly connected to a floor slab, and the overhanging connecting beam 2 partially extends to the outside of the floor slab, the discharging platform body 1 is fixedly connected to a portion of the overhanging connecting beam 2 extending to the outside of the floor slab, the horizontal supporting system includes two sets of supporting structures disposed on left and right opposite sides of the overhanging connecting beam 2, and the two sets of supporting structures are fixedly connected to the floor slab and clamp the overhanging connecting beam 2 therebetween.
In this embodiment 1, the tie-beam 2 of encorbelmenting is two, and through pre-buried structure 5 in the middle of the floor and with floor fixed connection, simultaneously, whole formula of encorbelmenting material platform has still set up the suspension cable to draw the bearing to the platform body of unloading 1.
Referring to fig. 2, for the overhanging connecting beam 2, in the case of the lateral wind load, the conventional overhanging material platform is mainly supported by the pre-embedded structure 5, and in this embodiment 1, because the two side supporting structures clamp the overhanging connecting beam 2 between the two side supporting structures, and the position is limited in the left-right direction, the two side supporting structures can cooperate with the pre-embedded structure 5 to support the wind load transmitted by the overhanging connecting beam 2, so as to reduce the risk of the overhanging connecting beam 2 that the overhanging connecting beam 2 accidentally shakes in the case of the lateral wind load and the accidental failure of the fixed connection between the overhanging connecting beam 2 and the floor slab.
As for the contact manner between the cantilever attaching beam 2 and the supporting structure, the two may be rigid contact or elastic contact. In the preferred embodiment, the support structures on both sides apply opposite support forces to the overhanging joint beam 2 between them, that is, the support structures on both sides are in elastic contact with the overhanging joint beam 2 between them, and the support structures actively apply forces to the overhanging joint beam 2. Meanwhile, the supporting forces applied by the supporting structures on the two sides to the overhanging connecting beam 2 between the supporting structures on the two sides are different in magnitude, so that the resultant force of the supporting forces on the two sides can offset wind load.
It can be understood that if the supporting structures on both sides are in rigid contact with the cantilever connecting beam 2, during installation, it must be ensured that the cantilever connecting beam 2 can be clamped between the supporting structures on both sides and firmly abut against the supporting structures while being fixedly connected with the embedded structure 5. Due to the limitation of the concrete pouring process level, the concrete pouring process is extremely difficult to achieve in the actual assembly process, and the elastic contact has lower requirements on assembly and is more applicable.
In addition, the lateral wind load borne by the cantilever beam 2 may have a large difference in direction and magnitude at different time periods.

Referring to fig. 3, an implementer can estimate the wind load according to the wind power and the wind direction, adjust the position of the sliding seat 32 relative to the fixed platform 31 and the floor slab in advance, adjust the length of the compression elastic member 33, change the supporting force applied to the cantilever connecting beam 2 by the compression elastic member 33, and further adjust the magnitude and direction of the supporting force applied by the compression elastic members 33 on both sides and borne by the cantilever connecting beam 2, so that the horizontal wind load borne by the wind cantilever connecting beam 2 can be offset.
More specifically, in this embodiment 1, the supporting structure acts on the overhanging joint beam 2 between the position where the overhanging joint beam 2 is fixedly connected to the floor slab and the position where the overhanging joint beam 2 extends out of the floor slab.
More specifically, with regard to the implementation of the above-described support structure, the function of locking the position of the sliding seat 32 with respect to the fixed floor platform 31 is implemented:
in embodiment 1, a screw 34 extending in the same direction as the sliding groove is accommodated in the sliding groove, a ball nut is arranged on the sliding seat 32, and the screw 34 penetrates through the sliding seat 32 and forms a ball screw nut pair with the ball nut on the sliding seat 32; the two ends of the lead screw 34 are respectively inserted into the fixing table 31 and the overhanging connecting beam 2, and can rotate around the axis of the lead screw relative to the fixing table 31 and the overhanging connecting beam 2.
With the rotation of the screw rod 34 around its axis, the sliding seat 32 converts the above-mentioned rotation motion into its own movement motion along the axial direction of the screw rod 34, i.e. the extending direction of the sliding groove, through the ball nut, and the sliding seat 32 can be stationary at any position in its stroke, so as to facilitate the adjustment of the elastic force of the compression elastic member 33 by the operator.
In the present embodiment 1, rolling bearings are respectively fitted to both ends of the screw rod 34, and the rolling bearings on both sides are fixedly disposed in the fixing base 31 and the cantilever connecting beam 2.
More specifically, in order to ensure that the compression elastic member 33 can be extended and retracted all the time in the left-right direction, the occurrence of accidents such as bending and the like can be avoided. In this embodiment 1, the compression elastic member 33 is a compression spring, and the compression spring is sleeved on the screw 34. In other embodiments, the compression elastic member 33 is a cylindrical nylon column, which is also sleeved on the screw rod 34.
Meanwhile, in order to ensure the contact effect between the compression elastic member 33 and the cantilever connecting beam 2, the elastic force generated by the compression elastic member 33 is uniformly transmitted to the cantilever connecting beam 2. In this embodiment 1, a contact plate 35 for abutting against the cantilever beam 2 is fixedly connected to one end of the compression elastic member 33 close to the cantilever beam 2, and the contact plate 35 is provided with a through hole for the screw rod 34 to pass through.
