Embodiment 1

[0059] A mechanized equipment for the construction of a concrete pipe gallery, comprising: an inner mold formwork part and a lifting trolley part for moving the inner formwork formwork into place.

[0060] See attached Figure 1-5 , the mold base part of the internal mold includes a door frame 1, a movable column 2, a column lifting support leg 3, a side template 4, a top template 5, and a translation driver 6, a transmission assembly and a motor 8.

[0061] 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...

Embodiment 2

[0077] On the basis of Embodiment 1, further speaking, the inner mold frame can be longitudinally spliced ​​into the required size by a plurality of inner mold frame units to adapt to different construction needs, and each inner mold frame unit can realize a motor 8 at the same time Drive eight translation drivers 6 to act synchronously. Two specific lectures: each internal mold frame unit includes two door frames 1, four movable columns 2, eight translation drivers 6, a motor 8 and a transmission shaft 7-1.

[0078] 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 formwork 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; ...

Embodiment 3

[0080] On the basis of Embodiment 1, further, see the accompanying Figure 8 , 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 method for placing and demoulding an inner mold of a concrete pipe gallery, comprising an inner mold frame and a lifting trolley for moving the inner mold frame in place; the inner mold frame includes a door frame, and Set the movable column, install the side formwork on the movable column, and connect the movable column with the door frame through the translation driver; install the top formwork on the top of the door frame; set the column lifting support leg at the bottom of the movable column, and adjust the height of the entire inner mold frame through the column lifting support leg ; At the bottom of the mast, there is also a bottom middle support leg that can be lifted and lowered. During construction, lift the trolley to lift the inner mold frame to move and initially put it in place, and adjust the position of the side formwork and its own height in combination with the inner mold frame to realize the formwork and demoulding work.

Description

technical field [0001] The invention belongs to the technical field of concrete construction of a pipe gallery, and in particular relates to a method for placing and demoulding an inner mold of a concrete pipe gallery. 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...
