Description
Technical Field
The utility model relates to a building templates erects technical field, specifically say and a spacing split bolt of navigation key.
Background
The traditional method of the split bolt technology for fixing the concrete template in the construction engineering construction is as follows: the two side templates are provided with holes, a round plastic sleeve is arranged in the holes through penetrating the two template holes, a metal bolt rod penetrates the round plastic sleeve, a transverse back edge is arranged, and pipe clamps are sleeved at two ends of the metal bolt rod to tighten fastening nuts.
The traditional split bolt technology for fixing the concrete template has the following defects: because the limiting device is not arranged, the positioning of the templates can be controlled only by a cement support rod arranged between the templates at two sides and the hand feeling of tightening the fastening nuts by operators, and because the strength of the templates is continuously reduced and is different in the repeated use process, the degrees of tightening the nuts by the operators are different, the sizes of the cross sections of the concrete are different; particularly, in the integrated engineering of the heat insulation structure, the strength of the inner side of the heat insulation template is very low, and a cement stay bar positioned between the inner side template and the outer side heat insulation template is easy to jack the inner side of the heat insulation template, so that the section size of concrete is reduced; therefore, in the common concrete formwork engineering or the heat insulation structure integrated formwork engineering, the verticality and the flatness quality of the concrete wall are difficult to control due to the traditional split bolts, and often exceed the standard, so that the later plastering decoration engineering amount is increased, and the engineering cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of above-mentioned prior art, and provide a spacing split bolt of navigation key, mainly solve the fixed concrete form of tradition to the problem that the bolt control concrete wall body hangs down straightness and roughness precision are poor.
The utility model provides a technical scheme is: a positioning key limiting split bolt is characterized by comprising a metal bolt rod, a positioning key, a fixed nut, a movable nut and a 3-type pipe clamp; one end of the metal bolt rod is provided with a positioning key, the other end of the metal bolt rod is provided with a fixed nut, the outer side of the positioning key is provided with a movable nut, and the inner sides of the fixed nut and the movable nut are respectively provided with a 3-type pipe clamp.
Preferably, the positioning key is arranged in the groove of the metal bolt rod, and the positioning key is flush with the outer diameter of the metal bolt rod.
Preferably, the fixing nut is fixed on the metal bolt rod.
The utility model has the advantages that:
1. because the nut at one end of the split bolt is fixed, an operator only needs to fasten the nut at one side and fasten the nut at the position at one time, the construction and installation operations are simple and convenient, and the working efficiency is improved;
2. the thickness of the concrete can be accurately controlled, the position of the template is controlled, the verticality and the flatness of the concrete are ensured, and the effect is particularly obvious in the heat insulation structure integrated engineering; because the strength of the inner side of the heat preservation template is lower, a cement brace rod positioned between the inner side template and the outer side heat preservation template is easy to jack the inner side of the heat preservation template under the fastening of a traditional split bolt fastening nut, so that the size of the section of concrete is reduced, and the verticality and the flatness of the concrete are poorer; the stroke of the fastening nut of the utility model is not controlled manually, the movable nut can be stopped after reaching the position due to the action of the positioning key, and the distance between the positioning key and the fixed nut is determined according to the actual engineering calculation, thereby accurately controlling the geometric dimension of the concrete and leading the concrete to achieve the perfect apparent effect;
3. the traditional operation process of the split bolt is basically not changed, the phenomenon that workers feel conflicted due to the change of a new process is avoided, and the split bolt is convenient to accept, adapt and operate by the workers.
