Problems solved by technology

[0002] There are many types of formwork used in the construction field. The steel formwork has the advantages of long service life and many times of operation, but the steel formwork is heavy to use, variable, and the operation is cumbersome, and it is not easy to demould; although the wooden formwork is light in weight, it is easy to use. Operation, but its strength is low, easy to open glue, short life, less operation times, and waste wood, generate a lot of garbage, pollute the environment; solid plastic formwork is easy to warp, denature, heavy, high cost, so it is not suitable for building formwork ;Hollow plastic formwork is a common building formwork. Its advantages are light and handy, can be used repeatedly, does not deform, does not bend, but its strength is low, not resistant to impact, easy to form holes, does not absorb nails, and is easy to pour gray

Embodiment 1

[0048] Embodiment one: see figure 1 , image 3 , a hollow filled plastic-steel building formwork, including a plane formwork surrounded by two parallel panels and surrounding side panels, the inner cavity of the plane formwork is fixed and connected longitudinally with stiffeners 5 perpendicular to the panels, and the stiffeners are connected at the same time The parallel panels on both sides play a certain supporting role, and the above-mentioned plane formwork and the stiffeners therein are all made of engineering plastics. At symmetrical positions between the two parallel panels, longitudinal grooves surrounded by double flanges 8 are respectively provided, and a hard support plate 6 is inserted and fixed between the two longitudinal grooves. The strip structure with a rectangular cross-section is made of a steel plate with a higher hardness coefficient than the plastic formwork, or a bamboo board, or a wooden board, or other hard material boards. The hard support boards a...

Embodiment 2

[0054] Embodiment two: see figure 2 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the middle parts of the two sides are respectively provided with hollow filled plastic-steel building templates with grooves 4 .

Embodiment 3

[0055] Embodiment 3: The picture is not drawn, and the content is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is: the middle parts of the three sides are respectively provided with hollow filled plastic-steel building templates with grooves.

Abstract

The invention relates to a hollow filled plastic-steel building template and a composite structure. The inner lateral surfaces of the building template are provided with longitudinal slots enclosed by double flanges respectively; hard supporting plates are inserted and fixed between every two opposite longitudinal slots; the centers of the two opposite lateral surfaces or three or four lateral surfaces of the building template are provided with grooves parallel to corresponding relatively-longer side edges respectively; and a lightweight filling material is filled into the cavity of the template. The composite structure consists of the template, corner connecting pieces and middle prisms, wherein the side edges of the corner connecting pieces are provided with longitudinal ribs which are matched with corresponding grooves on each side edge of the template; the middle prisms are matched with the grooves on each side edge of the building template; and simultaneously, each prism has a width which is twice that of the groove. The hollow filled plastic-steel building template integrates the advantages and characteristics of a steel formwork, a timber formwork and a hollow plastic formwork, has the advantages of strong strength, long service life, smoothness, easy de-molding, no bend, no deformation, lightweight and flexible mounting and dismounting, can improve the working efficiency and is applied to popularization and implementation.

Description

Technical field: [0001] The invention relates to a practical formwork in the construction field, in particular to a hollow-filled plastic-steel building formwork and a combined structure. Background technique: [0002] There are many types of formwork used in the construction field. The steel formwork has the advantages of long service life and many times of operation, but the steel formwork is heavy to use, variable, and the operation is cumbersome, and it is not easy to demould; although the wooden formwork is light in weight, it is easy to use. Operation, but its strength is low, easy to open glue, short life, less operation times, and waste wood, generate a lot of garbage, pollute the environment; solid plastic formwork is easy to warp, denature, heavy, high cost, so it is not suitable for building formwork Hollow plastic formwork is a common building formwork, which has the advantages of being light and handy, can be used repeatedly, does not deform, does not bend, but ...
