Embodiment Construction

[0010] The content of the invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0011] Elevation-adjustable super-flat floor formwork, including full-length 1-square steel guide rail, 2-square steel butt joint sleeve, several 3-angle steels, several 4-cross-through fastening bolts, and several 5-expansion bolts.

[0012] The full-length 1-square steel guide rail is composed of two parallel 40×60 square steels with a distance of 2 to 3 meters, and φ10 holes are drilled at a distance of 1 to 2 meters along the length direction for fixing with 4-crossing fastening bolts. The square steel joint part of the 2-square steel butt sleeve is connected by an inner sleeve. The length of the 2-square steel butt sleeve is 100-200mm, and the two ends are embedded in the 1-square steel guide rail by 50-100mm to avoid the 1-square steel There is a misalignment of the connecting part of the guide rail, which causes the ground height differ...

Abstract

The invention provides an elevation-adjustable superflat floor formwork, which comprises a square steel guide rail, square steel butt joint sleeves, a plurality of pieces of angle steel, a plurality of oppositely penetrating fastening screw bolts and a plurality of expansion screw bolts, wherein the square steel guide rail consists of two pieces of parallel square steel with the space being 2 to 3m; holes are drilled in the length direction at intervals being 1 to 2m and are used for fixing the oppositely penetrating fastening screw bolts; the square steel joint parts of the square steel butt joint sleeves are connected by internally connected sleeves; the length of the butt joint sleeves is 100 to 200mm; the two ends of the butt joint sleeves are embedded into the square steel guide rail for 50 to 100mm; a plurality of pieces of angle steel are used as connecting elements between the square steel guide rail and a structure base layer; the length of the angle steel is 80 to 100mm; a plurality of opposite passing fastening screw bolts are used as connecting fastening screw bolts between the square steel guide rail and the angle steel; the plurality of expansion screw bolts are in one-to-one correspondence to oval holes formed in the angle steel; and each piece of angle steel is anchored on a superflat floor structure base layer by two expansion screw bolts. The elevation-adjustable superflat floor formwork effectively solves the problem that the existing construction technology cannot meet the precision requirement of the superflat floor construction.

Description

technical field [0001] The invention relates to a formwork for indoor and outdoor floor elevation control, in particular to an adjustable-elevation super-flat floor formwork. Background technique [0002] According to the general requirements for the ground in the Chinese national standard "GB50209-2010 Construction Quality Acceptance Code for Building Ground Engineering", the height difference of 80% of the ground should not be greater than 4mm / 2m, and the height difference of 20% of the ground should not be greater than 6mm / 2m. 90% of the ground height difference should not be greater than 2mm / 3m, and 10% of the ground height difference should not be greater than 3mm / 3m. At the same time, the less the ground waveform is, the higher the flatness is when the same height difference is required within a certain distance. Uneven waves are not allowed on the ping. It can be seen that its flatness requirements far exceed the requirements of national standards. [0003] At prese...
