Embodiment Construction

[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0023] Such as figure 1 , image 3 Shown, a kind of composite formwork that steel bar truss and bottom form constitute, it comprises steel bar truss 2, tie bars 6 such as saddle nails etc. , Bottom rib 5. The web bars 3 of the steel truss and the bottom non-metal base form 1 are connected as a whole by tie bars such as saddle nails 6. If necessary, they can also be connected to the bottom bars 5 of the steel truss to form other non-metallic truss panels such as reinforced truss pressure cement boards or wood boards. Metal plate floor slab system; or the bottom formwork can also be lifted off by contact with a crowbar; moreover, if wooden formwo...

Abstract

The invention discloses a combination formwork composed of steel bar trusses and a bottom die. The combination formwork comprises the nonmetal bottom die. The multiple steel bar trusses are arranged on the nonmetal bottom die. Each steel bar truss comprises a space curve-shaped web bar. An upper bar is arranged on the top of each web bar. The two sides of each web bar are each provided with a bottom bar. Each upper bar and the corresponding bottom bars are distributed in a triangular mode. The steel bar trusses and the nonmetal bottom die are connected through a plurality of tie bars. The tie bars are connected with the nonmetal bottom die through the web bars or the bottom bars. The height of the web bars is larger than that of the triangles formed by the upper bars and the bottom bars. According to the combination formwork composed of the steel bar trusses and the bottom die, the bottom is flat and smooth, construction is completed, the appearance quality is good even when no processing is performed, the combination formwork is easy to operate, industrial assembly line production is facilitated, the production operation efficiency is greatly improved, manpower and material resources are saved, and the formwork decreases a large amount of occupied space and greatly improves the conveying efficiency.

Description

technical field [0001] The invention relates to the field of industrial and civil buildings, more precisely, it is a composite template composed of a steel bar truss and a bottom form. Background technique [0002] With the rapid development of multi-high-rise steel structures, higher requirements are put forward for the construction period. The industrial production of steel structure component factories has greatly shortened the construction period. The construction method of the floor slab has become an important factor affecting the construction period. The profiled steel plate slab with a certain rib height, which was widely used at one time, has the disadvantages of reducing the net height of the building, uneven lower surface of the floor slab, cumbersome binding of steel bars, difficult control of the spacing of steel bars and the thickness of the concrete cover. Contents of the invention [0003] The present invention mainly solves the technical problems existing ...
