Problems solved by technology

[0008] The invention provides a hanging basket jack preloading method, which solves the technical problems of the existing continuous beam hanging basket preloading construction method such as long time consumption and difficult operation, and realizes the convenience, time saving and material saving of the hanging basket jack preloading method. The resource consumption is less, which can ensure the timely backfilling of the cap foundation pit and the construction of the 0# block support foundation, so that the force on the bottom plate of the hanging basket is more uniform, and the preload of the hanging basket is closer to the actual construction situation. The technical effect of simpler processing of buried components and easier operation

Embodiment 1

[0038] In Embodiment 1, a hanging basket jack preloading method is provided, please refer to Figure 1-Figure 7 , the method includes:

[0039] Step 1: During the construction process of the continuous beam A0# section, pre-embed the embedded parts for the construction of the reaction force frame. The embedding position is on the end web plate of the A0# section. Specifically, it is the first cast-in-place segment at the top of the middle pier;

[0040] Step 2: Assemble the I-beam components according to the size, and weld with one side of the embedded steel plate;

[0041] Step 3: Install the jack. The upper and lower ends of the jack are equipped with I-beams to distribute the force. Between the double I-beams at the lower part of the jack and the bottom form, N roads of wooden boards placed at equal intervals are laid longitudinally. The said N is greater than or equal to A positive integer of 2, and carry out jack debugging;

[0042] Step 4: Set up the control points fo...

Abstract

The invention discloses a prepressing method for a hanging basket jack. To make the stress state of the pressure test loading process coincide with that of the practical construction work, the jack is adopted for conducting loading and prepressing to a hanging basket at the midspan of a beam bottom plate of a section 1#, namely a reaction frame is arranged on the end face of a web of a section 0#, by utilizing the opposite acting force of the reaction frame, the opposite acting force is transformed to the bottom plate of the hanging basket through the jack, a sleeper distributive girder or a square timber distributive girder and a wooden plate cushion for exerting the required prepressing load, the concrete load level of the heaviest section is simulated for conducting loading, the technical effects are achieved, namely the prepressing method for the hanging basket jack is convenient and timesaving, the consumption of material resources is little, it can be guaranteed that a pile cap foundation pit is backfilled timely, the construction of a block support foundation 0# is guaranteed, the bottom plate of the hanging basket is stressed more uniformly, the prepressing load of the hanging basket is closer to the practical construction conditions, the processing of the reaction frame and embedded components is simpler, and the operation is easier.

Description

technical field [0001] The invention relates to the research field of hanging basket construction, in particular to a method for preloading a hanging basket jack. Background technique [0002] The hanging basket is the main equipment in the cantilever construction. According to the structure, it can be divided into four types: truss type, cable-stayed type, steel type and mixed type. According to the requirements of the concrete cantilever construction process and the requirements of the design drawings for the hanging basket, comprehensively compare the characteristics, weight, steel type, construction technology, etc. of various forms of hanging baskets; the design principles of the hanging basket: light weight, simple structure, firm and stable, forward movement It has the characteristics of convenient assembly and disassembly, strong reusability, small deformation after being stressed, and sufficient space under the hanging basket, which can provide a large construction ...
