Method for accurately positioning arc-shaped railing glass
InactiveCN109914721APrecise positioningQuick and easy on-site installationBuilding material handlingStairway-like structuresWear resistantArchitectural engineering
The invention relates to the technical field of location of arc-shaped railing glass, and discloses a method for accurately positioning arc-shaped railing glass. The method comprises the following steps: S1, using a measuring tool to perform field measurement and sending out, and recording data; S2, leaving a margin at an arc-shaped railing with a width dimension consistent with the width of the railing, and placing a steel channel along the length direction; S3, welding inner and outer steel plates, and then arranging same in the steel channel in a locating way; S4, welding a steel plate on the side face of the inner steel plate, arranging a wear-resistant rubber plate at the outer side of the welded steel plate and then fixing by using bolts; S5, finally, fixing a steel plate transversely on the floor ground by using expansion bolts, and performing fine finishing so as to realize accurate positioning of the arc-shaped railing glass. The method for accurately positioning the arc-shaped railing glass adopts welding at the glass fixing position, thus enabling positioning to be more accurate; furthermore, fixed-length processing is adopted, so that on-site installation is quick; a glass base is formed in a way of fixing the steel plate with the bolts, so that the safety factor is higher.

Construction method of wiener plate light composite grouting wall system
InactiveCN110984437AFireproofWith insulationWallsClimate change adaptationLine tubingArchitectural engineering
The invention relates to a construction method of a wiener plate light composite grouting wall system. The method comprises the following steps of material selection and thickness determination, non-bearing partition wall steel keel manufacturing and installation, wiener plate installation, pipeline manufacturing and laying, light composite grouting filler filling and light composite grouting material wall joint treatment. A grouting wall constructed by the construction method can achieve the performances of light weight, high strength, water resistance, fire resistance, heat insulation, goodsound insulation performance, environmental protection and the like. A face plate and a keel can be directly installed and grouted after being machined in a factory and reaching the site, complex construction procedures such as ring beams, structural columns, steel bars and the like existing in a traditional wall body are avoided, the construction speed is high, no pollution such as waste materials, dust and noise is caused, the construction quality and the construction safety of the wall body can be better guaranteed, the site civilized construction is facilitated, and the construction methodhas the obvious characteristics of reliable, safe and efficient construction and advanced technology.
