Abstract

The utility model discloses a construction engineering plastic formwork. The long edges of a soleplate 1 are fixedly connected with frames 2; a face plate 3 is arranged above the soleplate 1, and the long edges of the face plate 3 are fixedly connected with the frames 2; reinforcing ribs 4 are used for connecting the face plate 3 and the soleplate 1. All components are extruded and formed integrally, and the arrangement of reinforcing beams and reinforcing ribs can satisfy the requirements of construction to rigidity and strength; due to the incompatibility of engineering plastics and cement, dismantlement after casting maintenance can not cause surface damage to cross beams or columns, which enhances engineering quality; meanwhile, formworks can be connected and installed conveniently, quickly and firmly.

Description

Building engineering plastic template

The utility model relates to general purpose formwork or modular shuttering element in the building operations, particularly the form surface being of plastic member.

In China's building trade engineering construction, on-the-spot pouring crossbeam, column adopt wooden template the earliest, because wooden template need consume a large amount of timber, and template when dismounting splitting takes place easily, must change for a short time when reusing greatly, waste is serious, for the abundant China of the forest reserves, urgent need is sought substitute products to protect forest resources, in addition, the wooden template scene of generally taking is got material, is pieced together nail, electric saw noise pollution environment, therefore, should be as far as possible few with or need not wooden template; Use at present steel template more generally, it has overcome the problem of timber waste, noise pollution, but there is following defective in it: (1) cost height, and every square metre of average price is about 280 yuan, the 3-4 that is equivalent to wooden template is doubly; (2) than great, lifting splicing and dismounting are all very difficult in the construction; (3) steel and cement have certain affinity, and demoulding difficulty is dismantled template simultaneously and easily crossbeam or column surface produced butcher cuts, influences workmanship.

The purpose of this utility model is to provide a kind of reasonable in design, rigidity and intensity all to satisfy the building engineering plastic template of construction requirement.

For achieving the above object, the utility model is taked following technical scheme: the long limit and the frame 2 of base plate 1 are affixed, panel 3 place on the base plate 1 and its long limit and frame 2 affixed, connect by reinforcing rib 4 between panel 3 and the base plate 1.

To snap in the degree of depth best so that be connected firmly for the steel card when making frame as joint, in the such scheme cross section of panel 3 be two ends low in the middle of high symmetrical broken lines.

For integral rigidity and the intensity that makes template satisfies the building operations requirement, reinforcing rib 4 vertically is provided with and is 2 roads or more than 2 roads along plastic formwork in the such scheme.

According to technique scheme as seen, frame 2 had both had the function of strengthening reinforcing, again as two joints that template connects in the construction, adopt board-like steel card to block frame and promptly finish connection, very convenient, fast, having solved the steel template adds back-shaped card connection and brings the very inconvenient problem of mounting or dismounting by wearing pin, each parts has satisfied the requirement of building operations to rigidity and intensity by being provided with of integral extrusion moulding and panel and reinforcing rib, engineering plastics and cement is affinity not, can not cause crossbeam or column surface damage when dismantle pouring maintenance back, improve workmanship; Because engineering plastics proportion is little, template can be designed to section bar, during use as required, select suitable length, settle at one go, on length, need not on-the-spot polylith template splice, reduce the splicing number of times and reach minimizing spillage chance, saving of work and time helps the reduction of erection time, in addition, the prices of raw and semifnished materials lower (suitable) with wooden price, and recyclable, so can reduce production costs significantly, help reducing construction engineering cost.

Description of drawings:

Fig. 1 is a 250mm plastic formwork section material section structural representation.

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, base plate 1, frame 2, panel 3 and reinforcing rib 4 are taked monolithic extruded or the injection moulding one-shot forming, and the long limit and the frame 2 of base plate 1 are affixed, stencil design becomes serial section bar, cuts out as required and cuts suitable length, one-time-reach-place, need not splice saving of work and time in the polylith scene; For satisfying rigidity and requirement of strength, can save material again, between two frames 2 across panel 3 for two ends low in the middle of high symmetrical folding face, 3 row reinforcing ribs 4 are set between panel 3 and the base plate 1, frame 2 is made hollow type, make frame both have and strengthen reinforcing function, can be used as two horizontal interconnective joints of template in the construction again, adopting tabular steel card to block frame can connect template securely, directly the steel card is taken off during dismounting to get final product, very convenient, fast, be beneficial to the reduction of erection time; Can not cause simultaneously crossbeam or column surface damage; Template width specifications difference, reinforcing rib 4 columns are provided with difference, and ordinary circumstance 250mm-350mm selects 3 row reinforcing ribs, the above above reinforcing rib of 4 row of selecting of 400mm.

Claims

1, a kind of building engineering plastic template, the long limit of base plate (1) is affixed with frame (2), it is characterized in that: panel (3) is positioned at base plate (1) top and its and grows between limit and the frame (2) affixedly, is connected by reinforcing rib (4) between panel (3) and the base plate (1).

2, building engineering plastic template according to claim 1 is characterized in that: on the cross section of plastic formwork, middle high symmetrical broken line is hanged down at the two ends that are shaped as of panel (3).

3, building engineering plastic template according to claim 1 is characterized in that: reinforcing rib (4) vertically is provided with and is 2 roads or more than 2 roads along plastic formwork.
