Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments: a simple sliding form device for shaft concrete lining, including a template 3 as a concrete shaft wall forming mold, an enclosure 2 for reinforcing the template 3, and a A lifting system for lifting the entire sliding form; the overall shape of the enclosure 2 is cylindrical, and a supporting truss 1 is fixed inside; the formwork 3 is fixedly connected to the outer wall of the enclosure 2; the lifting system includes a lifting Frame 4, jack 5 and climbing rod 6, lifting frame 4 is fixedly arranged on the periphery of the top of enclosure 2, jack 5 is fixedly arranged on lifting frame 4, climbing rod 6 is located outside template 3, and passes through lifting frame 4 and jack 5 .

The formwork 3 is a mold for forming the concrete 8 shaft wall, and its quality (mainly including stiffness and surface smoothness) directly affects the forming and appearance quality of the poured concrete 8 . As an embodiment of the present utility model: the template 3 is made by bending δ5mm steel plate (Q235 steel), and vertical support ribs 7 are welded between the outer wall of the enclosure 2 and the template 3, and a support rib 7 is arranged for each 50cm The rib 7 adopts No. 6 channel steel as the supporting rib 7, which is welded and fixed with the overall frame skeleton. The formwork 3 is 1.2m high, and the taper of the formwork 3 is controlled to be less than 5 mm, that is, the upper opening of the formwork 3 is 2.5 mm larger than the design size in the vertical direction, and the lower opening is 2.5 mm smaller than the design size, so as to be released from the concrete 8 smoothly.

The enclosure 2 is mainly used to reinforce the formwork 3, and there are 3 lines in total, which are welded and fixed with the supporting ribs 7 of the formwork 3, and welded with the upper and lower side beams of the truss girder, so that each formwork 3 becomes a whole. Enclosure 2 is welded with ∠80×7 angle steel. Due to the large vertical load and lateral force during the concrete construction process, in order to ensure the strength and rigidity of the operation panel, the ∠75×6 angle steel is used to process it into a truss structure.

The auxiliary working table 10 is suspended and fixed on the truss beam at the bottom of the truss 1. It is a working platform for concrete 8 maintenance, surface repair and embedded parts treatment. It is welded with Φ22 steel bars, and the upper layer is covered with δ=5cm slabs, and the distance from the well wall behind the well lining is 250mm.

The checkered steel plate 9 with δ=5mm is laid on the truss beam at the top of the truss 1 to form an operation platform.

The lifting frame 4 is the connecting member between the sliding formwork 3 and the auxiliary work plate 10. It is mainly supported on the climbing rod 6 by the jack 5 installed on the top. The entire sliding form load will be transmitted to the climbing rod 6 through the lifting frame 4. By operating the hydraulic pressure The console makes the hydraulic jack 5 climb on the climbing rod 6, thereby driving the entire sliding form body to slide upward. Lifting frame 4 is welded with [18 channel steel and δ10mm steel plate, and the number of lifting frame 4 is calculated according to "Technical Specifications for Construction of Sliding Formwork for Hydraulic Structures".

Select the QYD-100 jack 5 with a rated load capacity of 10 tons, a design load capacity of 5 tons, a climbing stroke of 30mm, and a QYD-36 self-leveling hydraulic console for the hydraulic console. High-pressure oil pipe: use φ16mm for the main pipe; use φ8mm for the branch pipe, use straight pipe joints and six-way joints to connect with the console and 5 jacks in groups, and all jacks 5 should be connected in groups to form a hydraulic system.
