Abstract

A hard and soft template for concreting is characterized in that the template is arranged in two layers, wherein the outer layer is a high tensile steel wire mesh supported by lightweight steel frame, and the inner layer is a soft air-permeable and water-permeable fabric layer as the lining. The utility model enables the template to play comprehensive effects in aspects of removing water, ensuring construction quality, facilitating removal, etc.

Description

The hard and soft template that is used for concreting

Technical field

The utility model relates to the template that is used for fluid concrete in the building operations.

Background technology

Template is one of most important construction tool in the construction of building structure steel concrete, and form work engineering generally accounts for the 20%-30% of reinforced concrete work expense, the 30%-40% of the amount of labour used, about 50% of duration.On construction technology, many height, difficulty, big engineering mainly concentrate on the concrete structure engineering, and in the concrete work, major technique concentrates on again on the form work engineering, and the mould plate technique problem has solved, and workmanship just can get on.

As the template of concreting, can be divided into gang form of steel form, wooden form, synthetic materials template, bamboo-wood plywood or different materials or the like by material property now.Using more mould material is steel form and bamboo-wood plywood.But there are some unsurmountable disadvantages in actual use in these templates, comprising: during fluid concrete, excessive moisture in the compound and air can not be discharged, and form common quality defects such as sand holes, crackle or pitted skin easily; During form removable, because the rigidity of template, the concrete absorption affinity after the sclerosis has formed makes a concerted effort, and must increase difficulty of construction and danger so on the one hand with crowbar or the barbarous dismounting of other instruments, also template and concrete is caused damage on the other hand.Have some to improve one's methods yet, promptly increase the smoothness of template inner surface or brushing interleaving agent to reduce absorption affinity, it is not firm that the way of this reduction concrete surface absorption affinity usually can cause rendering layer to adhere to again, phenomenon such as produce the hollowing of rendering layer or come off.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of hard and soft template that is used for concreting is provided, and makes template get rid of moisture, guarantee construction quality, be easy to aspect such as dismounting and have resultant effect.

The utility model technical solution problem adopts following technical scheme:

The design feature that the utility model is used for the hard and soft template of concreting is that described template is divided two-layer setting, and skin is the high-strength steel silk screen that is supported by light steel frame, and internal layer is the flexible layers of breathable fabric as liner.

The design feature that the utility model is used for the hard and soft template of concreting also is:

The edge of described steel frame is set to be used for the bayonet socket of snapping tissue layer, is provided with fastener in the bayonet socket.

Bayonet socket is set is " C " shape, fastener is a rod member that can be resisted against " C " shape bayonet socket internal orifice place, is "T"-shaped interval on the rod member one group of articulated stand is set, and the other end of articulated stand is hinged on the sidewall of " C " shape bayonet socket.

Rod member is the outer steel pipe that is coated with rubber layer.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model rigid system is to give the stressed system of light steel frame with the power transmission of high-strength steel silk screen, has alleviated template weight, and can add more function on template, comprises length-adjustable light steel frame being set to adjust the size of template; Flexiblesystem is to adopt flexible layers of breathable fabric, can guarantee the discharge of the empty G﹠W that the concrete surface that just watered is unnecessary, and the ratio value of reduction concrete surface water and cement improves concrete intensity and abrasion resistance.Guaranteed also that in addition concrete keeps high humility between curing time, reduced the risk that micro-cracks produces.Thereby make concrete surface become smooth, densification greatly reduces the sand holes and the common quality defects such as crackle or pitted skin on surface, can strengthen the erosion of concrete component opposing foeign element, as weathering, carbonization, chloride, microorganism etc. are improved concrete durability.

2, the strength that is attached together as a piece of cloth and glass water is far smaller than the strength that two blocks of glass are attached together; the utility model template is that cloth cover contacts with concrete; can be easy to remove; avoided the cruelty dismounting of template; can protect well concrete finished product; also protect the workman and the template of dismounting, improved efficiency, material turnover and product quality.

Fig. 4 is the utility model fastener structural representation.

Number in the figure: 1 light steel frame, 2 high-strength steel silk screens, 3 tissue layer, 4 fasteners, 41 rod members, 42 articulated stands, 5 bayonet sockets.

Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings

The specific embodiment

Referring to Fig. 1, Fig. 2, in the present embodiment, template is divided two-layer setting, and skin is the high-strength steel silk screen 2 that is supported by light steel frame 1, and internal layer is the flexible layers of breathable fabric 3 as liner, also can be bamboo matter layer etc.The edge of steel frame 1 is set to be used for the bayonet socket 5 of snapping tissue layer 3, is provided with fastener 4 in the bayonet socket.

Referring to Fig. 3, Fig. 4, bayonet socket 5 is " C " shape, fastener 4 is the rod members 41 that can be resisted against " C " shape bayonet socket internal orifice place, rod member 41 is "T"-shaped interval one group of articulated stand 42 is set, the other end of articulated stand 42 is hinged on " C " shape bayonet socket sidewall, rod member 41, is clamped on tissue layer 3 in " C " shape bayonet socket when articulated stand 42 stretches for the outer steel pipe that is coated with rubber layer.

In concrete the enforcement, outer field light steel frame 1 and high-strength steel silk screen 2 press working load design, satisfy under the prerequisite of force request light as far as possible.

The flexible layers of breathable fabric 3 of internal layer is held on the light steel frame 1, goes along with sb. to guard him concrete mixture on the one hand and is unlikely to leak, and allows excessive moisture and air in the compound overflow in addition, form closely knit concrete, the most important thing is that when form removable because inner lining material is flexible, the concrete after the curing and the absorption affinity of mould can not made a concerted effort as monoblock template formation in the past, be easy to stripping, the saving of labor, laborsaving, and also very little to concrete and template infringement, make concrete surface closely knit, smooth.
