Technical Field
The invention relates to the technical field of constructional engineering, in particular to a vertical gusset plate bolt anti-falling device.
Background
A large amount of steel structures and steel-concrete composite structures are used in domestic constructional engineering, and the steel-concrete composite structure has the advantages of excellent performance, light weight, quick installation and construction and the like. The connection of the steel structures mainly adopts the forms of rivet connection, welding seam connection, bolt connection and the like. The bolt connection has special advantages in the aspects of construction difficulty, speed, quality and the like, and is widely applied to steel structures. At present, more friction type high-strength bolts are used for connection, and shearing force is transmitted by means of friction force between the bolts and members. Due to the combined action of multiple factors such as the defects of the high-strength bolt material, the difference of the actual construction process, the stress redistribution of the bolt group, the fatigue failure of the bolt, the delayed fracture and the like, the fracture condition can occur after the structure is operated. The single bolt fracture is difficult to predict, and the prevention and control degree of difficulty is big, and is with high costs, and after the bolt that part quality is heavy or the mounted position is high falls, the secondary damage is big, causes the harm easily to people, car, thing etc.. Generally, anti-throwing nets are usually used in buildings for preventing objects from falling from the tops of the structures, but at present, no simple and effective method for preventing bolts from falling is available. Therefore, there is a need for a vertical gusset plate bolt fall-preventing device suitable for steel structures and reinforced concrete composite structures, which can prevent bolts from falling from the steel structures.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a vertical gusset plate bolt falling prevention device which is suitable for a steel structure and a reinforced concrete combined structure and can prevent a bolt from falling from the steel structure.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a vertical gusset plate bolt anti-falling device comprises a steel beam, wherein vertical gusset plates are fixed between flange plates of the steel beam through bolts, horizontal gusset plates which are vertically fixed on the vertical gusset plates through bolts are arranged on a web plate of the steel beam at intervals, and a transverse top framework and a transverse bottom framework are respectively and fixedly arranged on the inner sides of the flange plates of the steel beam; the both sides of tip all are fixed between top skeleton and the end frame and are provided with annular longitudinal frame, are located the fixed net of preventing weighing down that is provided with between two longitudinal frame of girder steel homonymy.
Furthermore, a stiffening plate vertically penetrating through the longitudinal framework is fixedly arranged between the end parts of the flange plates of the steel beam, and a hole capable of allowing the longitudinal framework to penetrate is formed in the connecting position of the stiffening plate and the longitudinal framework.
Furthermore, the top framework and the bottom framework are both composed of steel bars.
Furthermore, the aperture of the mesh of the anti-falling net is 5-25 mm.
Compared with the prior art, the invention has the following beneficial effects:
the invention has simple structure and low construction cost. Prevent weighing down net and skeleton texture and install around the girder steel that has the gusset plate in the former building, can improve the holistic effective area of device. The anti-falling net and the skeleton structure have light weight, small influence on the stress performance of the whole structure and large protection range. And strong adaptability is convenient for adapt to the volume of the steel beam to adjust the size of the component, and the component is suitable for various structural forms. The bolts fall on the anti-falling net and are easy to find in time, the bolts falling on the anti-falling net can be prevented from rolling for many times, and mounting points where the bolts fall off are easy to find according to the positions of the falling points.

Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, the vertical gusset plate bolt fall prevention device comprises a steel beam 9, wherein vertical gusset plates 1 are fixed between flange plates of the steel beam 8 through bolts 7, horizontal gusset plates 2 which are vertically fixed on the vertical gusset plates 1 through the bolts 7 are arranged on a web plate of the steel beam 8 at intervals, and a transverse top framework 4 and a transverse bottom framework 5 are respectively fixedly arranged on the inner sides of the flange plates of the steel beam 8; the both sides of tip all are fixed between top skeleton 4 and the end skeleton 5 and are provided with annular longitudinal frame 3, are located and are fixed between two longitudinal frame 3 of 8 homonymies of girder steel and prevent weighing down net 6.
The end parts of the flange plates of the steel beams 8 are fixedly provided with stiffening plates 9 which vertically penetrate through the longitudinal frameworks 3, and the connecting positions of the stiffening plates 9 and the longitudinal frameworks 3 are provided with holes through which the longitudinal frameworks 3 can penetrate. The position of the stiffening plate 9 corresponding to the longitudinal skeleton 3 is provided with a hole, and the annular longitudinal skeleton 3 can penetrate into the upper side and the lower side of the stiffening plate 9 respectively. Top skeleton 4 and end skeleton 5 constitute by the reinforcing bar, the whole weight of reduction device that can maximize, and vertical skeleton 3 adopts and fixes with top skeleton 4, end skeleton 5 welded mode again with the stiffener 9 suit of plate structure, and other forms can maximize the holistic steadiness of hoisting device relatively.
The invention has simple structure and low construction cost. Prevent weighing down net 6 and skeleton texture and install around the girder steel 8 that has the gusset plate in the former building, can improve the holistic effective area of device. The anti-falling net 6 and the skeleton structure have light weight, small influence on the stress performance of the whole structure and large protection range.
