Abstract
The utility model discloses a tool set for producing a reinforcing bar curve unit of a grid steel frame, which is characterized in that a tool set main body which is in an arc structure and is formed by an I-beam is arranged, and is the I-beam which is dispensed with the upper end of an inner arc side wing edge, and a short bar dowel and a small steel plate which are used for fixing and processing the reinforcing bar of the grid steel frame are welded on a web and the inner arc side of the tool set main body. The tool set has the advantages that the produced reinforcing bar curve unit of the grid steel frame has accurate camber, and can be operated by a plurality of persons, and the tool set which is produced by adopting the section steel is durable, has a simple structure, and is easy to process and difficult to deform.
Description
Technical field
The utility model relates to the tunnel construction field, specifically designs the making mould bases that is used for the grid steelframe curved unit master muscle that preliminary bracing uses in a kind of tunnel construction.
Background technology
The grid steelframe that uses in the construction of tunnel preliminary bracing adopts the processing space burst to make more; The on-the-spot method construction that connects moulding in the tunnel; The quality of the connection processing of each burst directly influences the precision of grid installation and the quality of preliminary bracing, is the key in the constructing tunnel.
At present, the grid steelframe that the tunnel preliminary bracing is used generally is made up of several curved unit according to the design profile line in tunnel, when fabrication and processing, does not have unified special tool, can't guarantee machining accuracy, and shortcoming such as operating efficiency is lower.
The utility model content
The purpose of the utility model is to provide a kind of tunnel construction grid steelframe master muscle curved unit to make mould bases at this, not only is well positioned to meet the required precision of design grid steelframe, and can well improves work efficiency.
The utility model is to realize like this; Construct a kind of grid steelframe master muscle curved unit and make mould bases; It is characterized in that: be provided with one adopt that i iron forms be the mould bases main body of arcuate structure; Said mould bases main body is to remove the i iron of inner arc side wing edge upper end, on the web of mould bases main body and inner arc side, is welded with bar dowel head and the little block plate that is used for fixing and processes grid steelframe master muscle.
Make mould bases according to the described a kind of grid steelframe master muscle curved unit of the utility model, it is characterized in that: the distance of bar dowel head and little block plate is greater than grid steelframe to be processed 0.5～1cm with main muscle diameter.
The advantage of the utility model is: the grid steelframe curved section master muscle unit radian of making is accurate, can many people operate simultaneously, and mould bases adopts section steel manufacture easy processing durable in use, simple in structure and not yielding.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation:
In order to overcome the deficiency of prior art, the utility model provides a kind of grid steelframe master muscle curved unit to make mould bases at this.Shown in Fig. 1-5: the described mould bases of the utility model; At first be provided with one adopt that i iron forms be the mould bases main body 101 of arcuate structure; Said mould bases main body 101 is for removing the i iron of inner arc side wing edge upper end, on the web 102 of mould bases main body 101 and inner arc side, is welded with bar dowel head 103 and the fritter steel plate 104 that is used for fixing and processes grid steelframe master muscle 112.
In operation; Make a mould bases (height of making the i iron of usefulness must greater than the height of grid steelframe) in the ratio of 1:1 with the I-shaped steel according to the radian of the grid steelframe curved unit of Tunnel Design and length; Slice off the upper half part (accompanying drawing 2) of the i iron mould bases inner arc side wing edge of making then with oxygen welding, on the web 102 of i iron mould bases and the inner arc face down bonding connect bar dowel head 103 and fritter steel plate 104 in order to fixing and processing grid steelframe with main muscle (being advisable greater than grid steelframe to be processed 0.5～1cm of bar dowel head 103 and fritter steel plate 104) with main muscle 112 diameters apart from d.
Remarkable result through above improvement the utility model is: the grid steelframe curved section master muscle unit radian of making is accurate, can many people operate simultaneously, and mould bases adopts section steel manufacture easy processing durable in use, simple in structure and not yielding.
Manufacturing process:
The making of mould bases: (height of making the i iron of usefulness must be greater than the height ' H ' in Fig. 5 I-I sectional drawing of grid steelframe to make a mould bases in the ratio of 1:1 with the I-shaped steel according to the radian of the grid steelframe curved unit of Tunnel Design and length; The main muscle length of making so just can meet design requirement); Slice off the upper half part of the i iron mould bases inner arc side wing edge of making then with oxygen welding, on the web 102 of i iron mould bases 101 and the inner arc face down bonding connect bar dowel head 103 and use main muscle in order to fixing and processing grid steelframe with fritter steel plate 104.Being advisable greater than grid steelframe to be processed diameter 0.5～1cm of bar dowel head and little block plate with main muscle apart from d; Its purpose is to make main muscle to put in smoothly; Will cause reinforcing bar to be put less than going in the space if d is not more than the diameter of main muscle, d can influence machining accuracy too greatly again.
The effect of mould bases described in the utility model: mould bases mainly is used for processing the main reinforcement of the curved unit of grid steelframe, ' is just having curved unit A109, curved unit B110, three curved unit of curved unit C111 to get up to form the curved portion of grid steelframe with the bolt assembly unit through angle steel among grid steelframe supporting Fig. 4 '.
Grid steelframe master's muscle and whole steelframe process engineering: through processing the radian that main muscle forms design with the way of gap that the identical reinforcing bar of grid steelframe length of curve is fixed on the mould bases web 102 bar dowel head 103 and the fritter steel plate 104 of welding.Be divided into plurality of units to the main muscle that processes according to the requirement of design drawing or the needs of practice of construction; Weld brace rod 105 then and angle steel 106 forms independently curved unit, during use with bolt 107 and nut 108 splicings (as ' shown in joint splicing Fig. 4 ').
