Hollow plastic building template capable of being conveniently replaced

Abstract

The invention discloses a hollow plastic building template capable of being conveniently replaced. The hollow plastic building template comprises a template, wherein a leakage hole is formed in the outer surface of the upper end of the template; a baffle is movably arranged on the outer surface of the rear end of the template; a first connecting rod is fixedly arranged on the outer surface of oneside of the template; a fixing plate is fixedly arranged on the outer surface of one side of the first connecting rod; a fixing hole is formed in the outer surface of the front end of the fixing plate; and a second connecting rod is fixedly arranged on the outer surface of the other side of the template. The hollow plastic building template capable of being conveniently replaced disclosed by the invention is provided with a buffer mechanism, a spherical bag and a threaded rod, so that expanded concrete can be prevented from being directly contacted with the template, and the surface of the template is prevented from being damaged. Calcium carbonate is arranged in the spherical bag, the calcium carbonate is heated to decompose and is capable of absorbing heat, and the template can be prevented from being heated to deform. Reinforcing ribs can be conveniently removed and can further be recycled, and excellent application prospects are brought.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a conveniently replaceable hollow plastic building template. Background technique [0002] In today's construction industry, with the continuous development of technology, the formwork is gradually adopting plastic formwork from the original wooden board material; the existing hollow plastic building formwork that is easy to replace has certain disadvantages when used. First, the concrete is heated. It will expand when it is used, and then squeeze the formwork, causing the surface of the formwork to deform. After several uses, the formwork will be damaged, reducing the number of times the formwork is used. Secondly, the material of the formwork is plastic. After the plastic is heated, it will be damaged. Deformation, if it reaches a certain temperature, the formwork will spontaneously ignite, which will affect the construction progress. Finally, after the formwork has been used ...

[0002] In today's construction industry, with the continuous development of technology, the formwork is gradually adopting plastic formwork from the original wooden board material; the existing hollow plastic building formwork that is easy to replace has certain disadvantages when used. First, the concrete is heated. It will expand when it is used, and then squeeze the formwork, causing the surface of the formwork to deform. After several uses, the formwork will be damaged, reducing the number of times the formwork is used. Secondly, the material of the formwork is plastic. After the plastic is heated, it will be damaged. Deformation, if it reaches a certain temperature, the formwork will spontaneously ignite, which will affect the construction progress. Finally, after the formwork has been used for a certain number of times, it will be scrapped due to surface deformation, and the reinforcing ribs inside the formwork will be dismantled. Difficulties will also be discarded together, resulting in a waste of resources and a certain impact on users. Therefore, we propose a hollow plastic building formwork that is easy to replace
