Technical Field
The invention relates to the technical field of curved-surface net rack construction, in particular to a permanent support replacing method for annular curved-surface net rack sliding construction.
Background
The curved net rack is one of novel roof structures, is a common high-order hyperstatic structure system in the current building field, further strengthens the self load capacity on the basis of changing the stress state of a conventional plane frame structure, has the characteristics of large span, large curvature, high height, strong integrity and arched shape, and is commonly used as a roof of buildings such as gymnasiums, movie theatres, exhibition halls, waiting halls, hangars and the like.
The domestic football field is an annular curved net rack (one of the curved net racks). In the construction process of the annular curved net rack, a plurality of sliding rails are arranged on a rack body (concrete piles), a plurality of sliding shoes are connected on the rails in a sliding manner, and the sliding shoes are used as a supporting structure of a plurality of nodes of the annular curved net rack; then the sliding action of the sliding shoes is utilized to enable the annular curved net rack to slide in place; after sliding in place, the sliding shoes are required to be cut and unloaded, and the sliding shoes are replaced and welded into permanent supports so as to keep the structure of the net rack stable.
In general, during the process of cutting and unloading the sliding shoes and replacing the sliding shoes with permanent supports, the sliding shoes are sequentially unloaded in a manner of cutting the sliding shoes from a design line and immediately replacing and welding the sliding shoes with the permanent supports, but because the heights and the structures of the permanent supports are fixed, and the stress of each part of the annular curved net rack is uneven, the stress uniformity of the parts of the annular curved net rack supported by the sliding shoes and the parts of the annular curved net rack not supported by the sliding shoes is not high due to the limitation of the heights of the permanent supports in the sequential replacement process, the situation that gaps are reduced after partial unloading and the sliding shoes are inconvenient to be plugged into the permanent supports may exist, and the deformation of the net rack structure after the sliding shoes are removed is relatively large, so that the unloading stability of the annular curved net rack is lower than the design value.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention provides a permanent support replacing method for sliding construction of an annular curved net rack, which can solve the problems that in the prior art, the permanent support is highly fixed, when a sliding shoe is sequentially unloaded, the sliding shoe is inconvenient to replace by the permanent support, and the overall stress uniformity of the annular curved net rack is low, so that the stability of overall unloading is low.
According to the embodiment of the invention, the permanent support for the sliding construction of the annular curved-surface net rack comprises a chuck fixed on a rack body and an upper support fixed on a net rack fulcrum, wherein the upper support is arranged on the upper side of the chuck and can vertically move relative to the chuck; the minimum distance between the upper support and the upper side and the lower side of the chuck is smaller than the height of the sliding shoe by 2-3cm.
Through adopting above-mentioned technical scheme, when changing the skid shoe into permanent support, because the minimum interval of chuck and upper bracket upside is less than the height 2-3cm of skid shoe, make the permanent support can be plugged into the change point easily, simultaneously, in the change process, the vertical slip of accessible upper bracket for the chuck changes the interval of both upper and lower sides, in order to guarantee that the permanent support can be to net rack fulcrum contact and shaping supporting role, thereby improve among the prior art and exist because of permanent support highly fixed, when changing a plurality of skid shoes, the condition that is inconvenient to change the skid shoe into the permanent support probably exists, and the whole atress homogeneity of annular curved surface net rack is not high, lead to the lower problem of steadiness of whole uninstallation, simultaneously through the regulation of permanent support height in order to improve the suitability.
Preferably, the clamping jaw of the chuck is close to the upper support, and one side close to the upper support is an inclined plane; the upper support comprises a seat plate and a plurality of connecting claws, the seat plate is fixed on a net rack fulcrum, the connecting claws correspond to the claws one by one, and the connecting claws are provided with guide surfaces matched with the inclined surfaces.
Through adopting above-mentioned technical scheme, when the interval of the upper and lower both sides of permanent support of adjustment, make its inside driving piece rotate through the spanner, drive a plurality of jack catchs of chuck along the radial removal of chuck, through the mutually supporting of inclined plane and guide surface for the connecting claw removes in the vertical direction, makes the upper support remove in the vertical direction for the chuck.
Preferably, the outside of chuck has seted up the spacing groove, the bedplate is fixed with the gag lever post, the vertical extension of gag lever post and lower extreme adaptation and sliding connection in the spacing groove.
Through adopting above-mentioned technical scheme, when the upper bracket carries out the removal of vertical direction for the chuck, the gag lever post carries out upwards or decurrent slip in the spacing inslot, simultaneously, the gag lever post is spacing in the spacing groove to prevent that the upper bracket from moving in the horizontal direction.
Preferably, the seat board is fixed with a protective sleeve, the upper end of the protective sleeve is fixed on the seat board, and the lower end of the protective sleeve is covered on the lower end of the chuck.
Through adopting above-mentioned technical scheme, the protective housing covers the connection structure between chuck upper end and chuck and the upper bracket, protects to prolong its life relatively.
Preferably, the lower end of the protective sleeve is provided with an avoidance groove for enabling a wrench to extend in, and a plurality of claws are indirectly driven to slide in opposite directions or in opposite directions.
Through adopting above-mentioned technical scheme, dodge the groove through setting up, form and dodge the effect to the spanner stretches into and drives the driving piece of chuck and rotate.
On the other hand, according to the embodiment of the invention, there is also provided a method for replacing a permanent support for slip construction of an annular curved net rack, comprising the following steps:
s1, after the annular curved net rack slides in place, inserting permanent supports outside the sliding rail one by one in a clockwise or anticlockwise direction;
s2, determining a starting point, and unloading the sliding shoes sliding on the sliding rails at the two ends one by one according to the clockwise or anticlockwise direction;
