Problems solved by technology

However, it is impossible to set up a full house support for water operations, and the traditional hoop technology is time-consuming and laborious. The hoop steel should have different pile diameters, low reuse rate, high cost, and the installation, disassembly and transportation of the hoop. Not convenient

Embodiment 1

[0020] Embodiment 1: A high-pile wharf cast-in-place beam formwork suspension support system includes: a plurality of support devices sharing double steel channels 2, and the support devices include external steel rods 1 pre-embedded in PHC pile core concrete , Double steel channel 2 fixed on both sides of the PHC pile, suspension steel bar 4, chain hoist 5. The PHC pile penetrates into the post-cast pile core concrete through the reserved opening, and the pile core concrete of the PHC pile is pre-embedded with the external steel rod 1. The pile core concrete poured after penetration is the concrete curing. After the curing is completed, the PHC pile and The pre-buried external steel rod 1 forms a whole, and the length of the external steel rod 1 on one side of the PHC pile is 1.5 times the sum of the lengths of the two upper or lower flanges of the double steel channel 2 on one side of the PHC pile. One side of each PHC pile is symmetrically provided with two external steel r...

Embodiment 2

[0031] Embodiment 2: as Figure 2-4 As shown, a high-pile wharf cast-in-place beam formwork suspension support device includes two sets of double-assembled steel channels 2 and external steel rods 1, and each set of double-assembled steel channels 2 is composed of two parallel channel steels with a gap 8 , the channel steel is formed by the web and the flanges on the upper and lower sides of the web to form a groove-shaped column, the webs of the two parallel channel steels are opposite to each other, and two groups of parallel double steel channels 2 are arranged oppositely, between which they are fixed The PHC pile is installed, and the double steel channel 2 is erected on the external steel rod 1 embedded in the pile core concrete of the PHC pile, and the external steel rod 1 vertically supports the double steel channel 2. This scheme uses double steel channel 2, whose structure is more stable than the existing single channel steel structure, and is vertically supported by ...

Abstract

The invention provides an installation method of a high-pile wharf cast-in-place cross beam template suspension supporting system. A high-pile wharf cast-in-place cross beam template suspension supporting device and a supporting system belong to the field of building construction equipment and are designed to solve the problem of construction support for a cast-in-place cross beam of a high-pile wharf. Two groups of double-spliced box iron are arranged, wherein the two groups of the double-spliced box iron are oppositely arranged on the two sides of a PHC pile. At upper flanges and lower flanges of each group of double-spliced box iron, a pair of lap joint welding plates is arranged every two meters, and the double-spliced box iron are hoisted to the two sides of the PHC pile and are adjusted to a fixed position by a chain block. The double-spliced box iron in the two sides of the PHC pile are corrected through a horizontal ruler, so that elevations of the double steel channel on the two sides of the PHC pile are kept consistent. The installation method of the high-pile wharf cast-in-place cross beam template suspension supporting system has the effect that a double-spliced box iron structure is used, the double-spliced box iron structure is more compact than a hoop structure and can provide supporting, stretching and locking vertically and horizontally, so that the structure is more stable, various structural positions can be adjusted to adapt to different pile diameter, and the structure is a detachable structure and has reusability.

Description

technical field [0001] The invention belongs to the field of building construction equipment, and in particular relates to an installation method for a suspension support system of a cast-in-place beam formwork for a high pile wharf. Background technique [0002] With the rapid development of water conservancy and port engineering construction industry, more and more wharf projects are being built. As one of the three structural forms of the wharf, the high-piled wharf is widely used in the port construction of our country. The construction of cast-in-place beams for high-piled wharves needs to provide support for the bottom formwork. However, it is impossible to set up a full house support for water operations, and the traditional hoop technology is time-consuming and laborious. The hoop steel should have different pile diameters, low reuse rate, high cost, and the installation, disassembly and transportation of the hoop. Not convenient. Contents of the invention [00...
