Civil engineering fundamental mold side ejector

Abstract

The invention discloses a civil engineering fundamental mold side ejector. The civil engineering fundamental mold side ejector is provided with a main sleeve, wherein a threaded adjustment hole communicated with the outer sides of the two ends of the main sleeve is formed in the center of the main sleeve, an adjustment rod is connected to one end of the threaded adjustment hole, and a positioning rod is connected to the other end of the threaded adjustment hole; the diameter of the adjustment rod is smaller than the diameter of the threaded adjustment hole, an external thread tightness adjustment head in screw thread fit with the threaded adjustment hole is arranged at the tail end of the adjustment rod, an outer hexagonal adjustment section is fixedly arranged on the head portion of the adjustment rod, a connecting shaft is fixedly arranged at the end of the outer hexagonal adjustment section, the connecting shaft is sleeved with a bearing, the bearing is sleeved with a connector, a connecting plate is arranged on one side of the connector, and a right-angle pressure head is connected to the inner side of the connecting plate. By means of the lead screw principle, flexible adjustment of length can be achieved, the tail end of the civil engineering fundamental mold side ejector can be inserted into a soil matrix or directly expanded and pressed onto the ground or other walls, the right-angle pressure head on the head portion can be adjusted by multiple angles, using is flexible, and stability is high.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a side top piece of a civil basic form. Background technique [0002] Civil engineering refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. General civil engineering projects include: housing, roads, water, drainage, flood control and transportation. However, most of the civil engineering mentioned today generally refers to minor civil engineering, including the primary construction of residences, public buildings, and structures. Such as pouring and masonry works for maintenance structures such as precipitation, earth excavation, foundation laying, and pouring of columns, beams, slabs and walls, as well as supporting steel bars and simple decorations. [0003] Taking the pouring and masonry engineering of maintaining structures such as laying foundations and pouring columns, beams, slabs and walls as an example, concre...

Problems solved by technology

[0004] However, due to the different heights of these formworks, it is necessary to use specific clamping devices according to actual needs. These clamping devices can only clamp two symmetrical formworks together from the top. However, because they are placed horizontally above the formwork, so It will become an obstacle when pouring cement, and it is not convenient for construction personnel to drag the vibrating pump in the foundation groove formed by the formwork, and the stability of this clamping device is not very good, and the part under the formwork is easy to loosen
