Abstract
The utility model discloses an overhanging type discharging platform secondary beam. A secondary beam body is a reverse triangular truss formed by connecting two triangular frame bodies in the same structure, each triangular frame body comprises an upper chord rod, a press rod and a diagonal lower chord rod, the upper chord rod is in horizontal arrangement, the press rod is vertically and downwards arranged at the end part of the upper chord rod, both ends of the diagonal lower chord rod are respectively and fixedly connected with the upper chord rod and the press rod, the cross section of the upper chord rod and the press rod is a T-shaped cross section formed by combining double pieces of angle iron, both ends of the upper chord rod are welded with fixed steel plates, and connecting holes are respectively arranged on the press rod and at the end part of the upper chord rod near the press rod position. The overhanging type discharging platform secondary beam has the advantages that the secondary beam is formed by combining the two triangular frame bodies in the same structure, the two triangular frame bodies are connected through screw bolts, the mounting and the dismounting are very convenient, during design, the load and stress calculation is carried out according to Building Structure Load Standard and Steel Structure Design Standard, the secondary beam is designed into various specifications according to the loading capability of the discharging platform, i.e., the standardized processing manufacture can be realized, the carrying requirement is met, and the construction safety is ensured.
Description
Technical field
The utility model relates to the overhanging type discharging platform, especially relates to a kind of overhanging type discharging platform secondary beam.
Background technology
At construction site, material transport is generally by the tower crane transhipment between building layer and the layer, and discharging platform is with the terminal of subsurface material to the upper strata transhipment, generally comprises console mode discharging platform and overhanging type discharging platform.
Traditional overhanging type discharging platform is as the beam of encorbelmenting (or claiming girder) with channel-section steel or i iron, secondary beam is generally also made by i iron or channel-section steel, be in the same place with Main Girder Welding, the secondary beam of this structure has brought trouble for installation, dismounting and the transportation of discharging platform: during installation, discharging platform is owing to dismantling, and is bulky, needs tower crane to assist, installation process is collided people or other objects easily, has unsafe factor; If with the rigid cutting of oxygen, also be difficult to after the cutting restore, when being transported to other building sites, an automobile is except drawing it, and other article can not load substantially, and carrying capacity is far from reaching, and also is a kind of waste to engineering cost.The secondary beam supporting capacity of this structure is limited simultaneously: because the height of channel-section steel or i iron is limited, thereby limited the supporting capacity of this kind secondary beam, stack load in order to obtain bigger permission, generally speaking, the way of taking secondary beam to encrypt, secondary beam need reach 1m can satisfy normal instructions for use together.If not as calculated, when spacing or channel-section steel model being set not reaching code requirement, will not bury accident potential to the job site safety in production.
Summary of the invention
The purpose of this utility model is to provide a kind of installing/dismounting convenient transportation, overhanging type discharging platform secondary beam that bearing capacity is high.
For achieving the above object, the utility model can be taked following technical proposals:
Overhanging type discharging platform secondary beam described in the utility model comprises the secondary beam body, and described secondary beam body is two inverted triangular truss that the identical triangle support body of structure is formed by connecting; Described triangle support body comprises the profound bar of tiltedly leaving behind that the horizontally disposed depression bar of profound bar, being arranged on profound boom end vertically downward and two ends are connected mutually with last profound bar, depression bar respectively.
The described cross section of profound bar and depression bar is the T type cross section that double angle is combined into, and the two ends of profound bar are welded with fixation steel plate described.
Profound boom end all offers connecting hole on the described depression bar and close depression bar position, is provided with connecting bolt in the connecting hole between two depression bars; The joint of profound bar is provided with the connection steel plate on two, and it is corresponding with connecting hole position on the profound bar on two respectively to be opened in the connecting hole that connects on the steel plate, is provided with profound bar connecting bolt in connecting hole.
Advantage of the present utility model is that secondary beam is combined by the identical triangle support body of two structures, connects with bolt between the two tripod bodies, mounts and dismounts very convenient; Carry out load and Force Calculation according to " loading code for design of building structures " and " Code for design of steel structures " during design, be designed to plurality of specifications, can realize the standardization processing and manufacturing, satisfied load bearing requirements, guaranteed construction safety according to the carrying capacity of discharging platform; Compare with traditional secondary beam of same bearing capacity, deadweight alleviates greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, overhanging type discharging platform secondary beam described in the utility model comprises the secondary beam body, and the secondary beam body is two inverted triangular truss that the identical triangle support body of structure is formed by connecting; The triangle support body comprises the profound bar 3 of tiltedly leaving behind that the horizontally disposed depression bar 2 of profound bar 1, being arranged on profound bar 1 end vertically downward and two ends are connected mutually with last profound bar 1, depression bar 2 respectively; The cross section of going up profound bar and depression bar is the T type cross section that double angle is combined into, and is welded with fixation steel plate 4,5 at the two ends of last profound bar 1; Profound bar 1 end all offers connecting hole on the depression bar 2 and close depression bar 2 positions, is provided with connecting bolt 6 in the connecting hole between two depression bars 2; The joint of profound bar 1 is provided with and connects steel plate 7 on two, and it is corresponding with connecting hole position on the profound bar 1 on two respectively to be opened in the connecting hole that connects on the steel plate 7, is provided with profound bar connecting bolt 8 in connecting hole.
The secondary beam of using with the overhanging type discharging platform of limit for tonnage 20KN is an example, and go up profound bar 1 and depression bar 2 and form by the angle steel of two L50 * 5: the length that goes up profound bar 1 is 900mm, and the fixation steel plate 4,5 that is welded on both ends adopts the steel plate of 116 * 80 * 5mm; The length of depression bar 2 is 400mm, and top and last profound bar 1 are welded as a whole; Profound bar 3 is the reinforcing bar of diameter 12mm down, two ends weld together with the angle steel of last profound bar 1 and depression bar 1 respectively, on the angle steel of depression bar 2 and on profound bar 1 all offer connecting hole near on the angle steel of depression bar 2 positions, use the connecting bolt 6 of diameter 14mm to connect between two depression bars 2, the joint of profound bar 1 is provided with and connects steel plate 7 on two, connect the steel plate that steel plate 7 adopts 50 * 160 * 12mm, be placed between two angle steel of profound bar 1, it is corresponding with connecting hole position on the profound bar 1 on two respectively to be opened in the connecting hole that connects on the steel plate 7, uses diameter 14mm to go up profound bar connecting bolt 8 and connects.It is an inverted triangular truss that the secondary beam that is shaped is installed, and generally each discharging platform needs three secondary beams.
