Embodiment 1

[0032] A method for overall sliding of an inner mold steel pipe support, comprising the following steps:

[0033] 1. Fix the bottom bracket of the bracket with the vertical pole of the bracket to prevent the bottom bracket from scraping the floor concrete when the bracket slips, causing damage to the rod and deformation of the bracket;

[0034] 2. Loosen the top bracket of the bracket and the side support of the bracket, and the roof formwork at the top falls onto the bracket, and is placed directly on the bracket to slide along with the bracket;

[0035] 3. Install the track, set one on the bottom plate corresponding to the middle of the bracket and on both sides;

[0036] 4. The bottom of the bracket is located in the gap of the bracket, and the corresponding track penetrates 3 I-beams vertically, and the vertical I-beam is lifted by a jack; the I-beam is topped at the bottom of a row of horizontal bars perpendicular to the I-beam.

[0037] 5. Set the pole beam at the botto...

Embodiment 2

[0052] The difference from the above-mentioned embodiment is that the positioning steel bars on both sides of the wheel frame are gradually inclined outward from top to bottom, and are in an inverted figure-eight when viewed from the direction perpendicular to the length of the track; the corresponding positioning steel bars on both sides of the wheel frame are The distance between the upper part at least beyond the pole beam is greater than the width of the bottom steel plate of the I-beam, and the middle part is connected with a restraining steel bar 66 corresponding to the pole beam area; the positioning steel bars on the same side are located at the top of the pole beam It is also connected with a strip ring 65 whose two ends cover the positioning reinforcement.

[0053] The inverted figure-eight shape ensures that the I-beam will not be hit, and ensures that the I-beam is directly placed in the figure-eight shape. At the same time, it can also position the docking position...

Embodiment 3

[0055] The difference from the above-mentioned embodiment is that the height raised by the jack in the step 4 is about 8 cm from the ground.

Abstract

The invention belongs to the field of buildings, and particularly relates to an integral sliding method and structure of an internal mould steel pipe supporting frame. The integral sliding method comprises the following steps that 1, a cork base of the supporting frame is fixed to a stand bar of the supporting frame, and the situations that when the supporting frame slides, a rod piece is damaged and the supporting frame deforms due to the fact that the cork base scratches base plate concrete are prevented; 2, a jacking of the supporting frame and a side-face supporting piece of the supporting frame are loosened, a top plate formwork located at the top falls onto the supporting frame, and the top plate formwork is directly placed on the supporting frame and can slide along with the supporting frame; 3, rails are installed on the positions, corresponding to the middle and the two sides of the supporting frame, of a base plate; 4, three strips of I-shaped steel corresponding to the rails longitudinally penetrate into the position, located at a gap of the supporting frame, of the bottom of the supporting frame, and the longitudinal I-shaped steel is jacked by adopting a jack; 5, carrying pole beams are arranged at the bottoms of the three strips of I-shaped steel, and then wheel sets matched with the rails are installed on the lower portions of the carrying pole beams; and 6, a steel wire rope pulls the supporting frame to integrally slide. According to the integral sliding method and structure of the internal mould steel pipe supporting frame, the needed time for setting up the internal mould supporting frame is effectively shortened, the construction progress is accelerated, meanwhile the project cost is saved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a method and structure for integral sliding of an inner mold steel pipe support. Background technique [0002] When constructing side walls and roofs by grading and excavating underwater tunnels, the most economical and feasible solution is to use waterproof split bolts, that is, between the outer corrugated support used to support the outer formwork and the inner formwork support system Multi-points are connected by cross-tie bolts, and then concrete is poured. This method needs to disassemble the inner mold support as a whole and then build the next section when pouring the next section. The construction time is long, the strength is high, and the efficiency is low. The inner mold support generally adopts a combined support composed of a steel pipe support and a bowl buckle support. Now the applicant adopts the formwork support system without pair of tie rods, but there...
