Abstract
The utility model discloses a maintenance tool for steel grid structure rod pieces, which comprises a connecting pipe; two ends of the connecting pipe are connected with transition bodies, connecting rod pieces and fasteners used for connecting chord members in sequence; the transition bodies are connected with the connecting rod pieces by threads; and the total length of the two connecting rod pieces and the connecting pipe is larger than the length of a grid unit. The maintenance tool for steel grid structure rod pieces has the following benefits that by adopting the structure, the whole maintenance tool can be fixed on the chord members at two ends of the rod pieces needing to be replaced by the fasteners so as to substitute for the replaced rod pieces temporarily, and new rod pieces are installed after the replaced rod pieces are disassembled; and the maintenance tool is simple in structure and low in cost, and can be manufactured and processed conveniently.
Description
Technical field
The utility model relates to a kind of steel grid structure of building, and specifically a kind of steel grid structure rod member maintenance tool is used for the maintenance works such as reinforcing, replacing of the upper and lower chord member of steel grid structure.
Background technology
Space truss structure is to improve the conventional design structure of span on the present engineering, and its construction technology level is quite ripe, and some complicated large span grid structures are in continuous appearance.In use,, cause rod member diseases such as bending, distortion to occur, have a strong impact on the safe in utilization of space truss structure owing to load increases or the load hanging position is selected reasons such as improper.Because space truss structure is integral hoisting or high altitude bulk in construction, therefore, maintenance or change the much inconvenience of rod member of disease, and have great structural safety risk when changing rod member.
Summary of the invention
In order to solve the inconvenience of changing rod member for grid, the utility model provides a kind of steel grid structure rod member maintenance tool, and the rod member that can temporarily replace needs to change is safe and effective and easy to operate.
In order to solve the problems of the technologies described above, technical solutions of the utility model adopt following measure:
A kind of steel grid structure rod member maintenance tool, it comprises tube connector, the two ends of this tube connector are connected with the transition body in turn, connect rod member and the buckle that is used to be connected chord member; Described transition body and connecting between the rod member by being threaded; Described two total lengths that connect rod member and tube connector should be greater than grid cell length.
Among the utility model embodiment, described transition body is a cone table.
Among the utility model embodiment, described buckle is the main body that an inside is provided with the circular hole consistent with the chord member diameter, and main body radially is provided with the adjusting bolt.
Among the utility model embodiment, described tube connector, transition body, connection rod member and buckle material are steel.
The beneficial effects of the utility model:
1. employing said structure can be changed overall fixed on the chord member at two ends of rod member by buckle at needs, the interim rod member that is replaced of replacing, and new rod member is installed in the rod member that will be replaced dismounting back.
2. simple in structure, make easy to process, with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Among the figure 1, tube connector, 2, the transition body, 3, connect rod member, 4, buckle, 5, regulate bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details, so that those skilled in the art better understand the utility model.
With reference to figure 1,2 one kind of steel grid structure rod member maintenance tool, it comprises tube connector 1, and the two ends of this tube connector are connected with transition body 2 in turn, connect rod member 3 and the buckle 4 that is used to be connected chord member; Described transition body 2 and connecting between the rod member 3 by being threaded; Described two total lengths that connect rod member 3 and tube connector 1 should be greater than grid cell length, value 20cm.
Described transition body 2 is a cone table, and an end diameter is consistent with tube connector 1 external diameter, and other end diameter is consistent with connection rod member 3.
Described buckle 4 is the main body that an inside is provided with the circular hole consistent with the chord member diameter, and main body radially is provided with regulates bolt 5.
Described tube connector 1, transition body 2, connection rod member 3 and buckle 4 materials are steel.
This practical actual design process is as follows:
1. material requirements
2. processing and fabricating
(1) according to the length of design drawing selection tube connector 1, processing length=L-400mm, L are the planning grid element length; Reprocessing transition body 2, transition body 2 first car silks, then with the welding of tube connector 1 equal strength, weld width hf=3mm,
(2) processing buckle, according to design drawing, statistics is the specification of profound rod member up and down, according to these specifications, processes corresponding buckle 4 sizes.Then the buckle 4 that processes with to be connected rod member 3 welding fixing.
3, key points for operation
Guarantee to possess following operating condition:
(1) during work high above the ground, needs the colligation safety belt above the special tool.
(2) buckle is stuck in and changes rod member ball node one lateral extent and can not surpass 20cm, if it is excessive to detect the rod member internal force of replacing, can adds one in addition at the opposite side of ball node and add steel grid structure rod member maintenance tool.
Claims (4)
1. steel grid structure rod member maintenance tool, it is characterized in that: it comprises tube connector (1), the two ends of this tube connector are connected with transition body (2) in turn, connect rod member (3) and the buckle that is used to be connected chord member (4); Described transition body (2) and connecting between the rod member (3) by being threaded; Described two total lengths that connect rod member (3) and tube connector (1) should be greater than grid cell length.
2. according to the described steel grid structure rod member of claim 1 maintenance tool, it is characterized in that: described transition body (2) is a cone table.
3. according to the described steel grid structure rod member of claim 1 maintenance tool, it is characterized in that: described buckle (4) is the main body that an inside is provided with the circular hole consistent with the chord member diameter, and main body radially is provided with regulates bolt (5).
4. according to claim 1,2 or 3 described steel grid structure rod member maintenance tools, it is characterized in that: described tube connector (1), transition body (2), connection rod member (3) and buckle (4) material are steel.
