Embodiment 1

[0047] The first square steel 45 and the first row of wooden longitudinal corrugations 431 are fixed by self-tapping screws, the second square steel 46 and the second row of wooden longitudinal corrugations 432 are fixed by self-tapping screws, and the first square steel 45 and the second square steel are fixed by self-tapping screws. 46 can be fixed with self-tapping screws, which is convenient for construction.

Embodiment 2

[0049] combine Figure 4 The first square steel 45 and the second square steel 46 are respectively welded with a first angle steel 47, and the first angle steel 47 is respectively fixed on the first row of wooden square backs and the second row of wooden backs by wood screws.

[0050] A first angle steel 47 is arranged on the square steel 44, and then fixed on the first row of wooden square back corrugations and the second row of wooden square back corrugations through the first angle steel 47 and wood screws, and special wood screws for wooden square connection can be used to connect Tight, connection can be guaranteed.

Embodiment 3

[0052] like image 3 and Figure 4 , the first square steel 45 and the second square steel 46 are arranged along the width direction of the rectangular formwork.

Abstract

The invention discloses a wooden formwork lower opening protection structure of a hydraulic plate-penetrating creeping formwork and a construction method thereof.The wooden formwork comprises a rectangular panel, batten transverse edges, batten longitudinal edges, square steel and back edges, the batten longitudinal edges comprise the first row of batten longitudinal edges and the second row of batten longitudinal edges, the first row of batten longitudinal edges are fixed to the rectangular panel in an attached mode, and the top ends of the first row of batten longitudinal edges are fixed to the batten transverse edges; the second row of batten longitudinal ridges are fixed to the bottoms of the ends, away from the panel, of the batten transverse ridges, back ridge structures are arranged on the sides, away from the rectangular panel, of the second row of batten longitudinal ridges, the square steel comprises first square steel and second square steel, and the first square steel is fixed to the bottom ends of the first row of batten longitudinal ridges and attached to the rectangular panel; the second square steel is fixed to the bottom ends of the second row of batten longitudinal edges. The combination of the double rows of batten longitudinal edges and the square steel ensures the overall strength of the wood formwork and the enhancement of the quality of the lower opening, avoids the damage of the lower opening after long-time use, ensures the quality of the lower opening, and ensures the quality of the joint.

Description

technical field [0001] The invention belongs to the technical field of climbing formwork construction, and particularly relates to a lower opening protection structure of a wooden formwork of a hydraulically penetrating board climbing formwork and a construction method thereof. Background technique [0002] Climbing formwork is the abbreviation of climbing formwork, also called jumping formwork. It consists of a climbing formwork, a climbing frame (some climbing forms do not have a climbing frame) and climbing equipment. Specifically, it includes a climbing formwork column, a jacking system, a top platform, a cantilever beam and two timbers installed at the bottom of the top platform. Formwork, which is poured between two wooden formwork, is an effective tool in the construction of high-rise structures such as shear wall systems, cylinder systems and bridge piers. [0003] When assembling the hydraulic through-board climbing formwork, the lower part of the wood formwork is ...
