Embodiment 1

[0041] An internal mold platform for pipe gallery construction, including a door frame 1, a movable column 2, a column lifting support leg 3, a side formwork 4, a top formwork 5, a translation driver 6, a transmission assembly and a motor 8.

[0042] The door frame 1 is composed of the top door beam 1-1, the bottom cross brace 1-2 and the side vertical brace 1-3. The top door beam is made of H-shaped steel or steel plate tailor-welded into an H shape, and can be bolted by multiple sections. to meet the use of sections with different widths; the side vertical braces 1-3 are fixedly arranged between the top door beam 1-1 and the bottom cross brace 1-2, and play the role of connecting the top door beam and the bottom cross brace. A side vertical brace 1-3 is respectively arranged on both sides of a bottom horizontal brace;

[0043] Described movable column 2 is positioned at the lateral (width direction) both sides of door frame 1, promptly arranges a movable column 2 respectivel...

Embodiment 2

[0053] On the basis of Embodiment 1, further speaking, the inner mold stand can be vertically spliced ​​into the required size by a plurality of inner mold stand units to meet different construction needs, and each inner form stand unit can realize a motor 8 at the same time Drive eight translation drivers 6 to act synchronously. Two specific lectures: each internal mold bench unit includes two door frames 1, four movable columns 2, eight translation drivers 6, a motor 8 and a transmission shaft 7-1.

[0054] The two gantry frames are arranged longitudinally at intervals in the front and back, and a movable column is arranged on both sides of each gantry in the transverse direction (width direction). To stabilize the structure and prevent the inner mold bench unit from being deformed by force, each movable column 2 is connected to the gantry part on its inner side through two translation drivers 6, that is, four translation drivers 6 are installed on each gantry 1; The motor ...

Embodiment 3

[0056] On the basis of Embodiment 1, further, see the accompanying Image 6 , the specific installation structure of the thrust bearing seat 6-3 and the rotating nut 6-2 of the translation driver 6 is: one end of the rotating nut 6-2 has a flange 6-21; the thrust bearing seat 6-3 includes The upper cover 6-31 and the base 6-32, the upper cover 6-31 and the base 6-32 are butted together by bolts, an installation cavity is formed between the upper cover 6-31 and the base 6-32, and the rotating nut 6- The flange 6-21 of 2 is installed in the installation cavity, and several turns are arranged between the upper surface of the flange 6-21 of the rotating nut 6-2 and the upper cover 6-31 of the thrust bearing seat 6-3. The ball 6-3a, the lower surface of the flange 6-21 of the rotating nut 6-2 and the base 6-32 of the thrust bearing seat 6-3 are also provided with some circles of balls 6-3b, the wing of the rotating nut 6-2 Several rings of balls 6-3c are also arranged between the ...

Abstract

The invention discloses a use method for an inner die rack for pipe gallery construction. The inner die rack comprises a door frame, movable vertical columns, vertical column lifting support legs, side die plates, a top die plate, a translation driver, a transmission assembly and a motor, wherein the movable vertical columns are located at the two transversal sides of the door frame, and the topsof the movable vertical columns and the outer end of a top door beam of the door frame are slidably installed; the side die plates are installed on the movable vertical columns, the top die plate is installed on the top door beam of the door frame, the movable vertical columns are connected with the door frame at the inner sides of the movable vertical columns through the translation driver, and the movable vertical columns are driven to move through the translation driver, so that driving for the translation movement of the side die plates is realized; and one vertical column lifting supportleg is arranged at the bottom of each movable vertical column, and the height of the whole inner die rack is adjusted through the vertical column lifting support legs. During construction, the inner die rack is capable of automatically adjusting the positions of the side die plates and the own height, so that in-place installation working for the side die plates and the top die plate, and die release working are realized.

Description

technical field [0001] The invention belongs to the technical field of pipe gallery concrete construction, and in particular relates to a method for using an internal formwork stand for pipe gallery construction. Background technique [0002] With the rapid development of urbanization, urban land resources are becoming more and more tense, and urban construction projects and public facilities are increasing day by day. Especially in the construction of various pipelines, if the planning and design are improper, repeated excavation will occur. Not only will it affect the normal traffic in the city, but it will also affect the service life of various pipelines. Through the application of comprehensive pipe gallery construction technology, the above problems can be effectively solved and the safe operation of various pipelines can be ensured. The concrete construction of the existing pipe gallery mostly uses wood formwork, steel formwork, etc., which takes a long time to disas...
