Abstract
The utility model provides a detachable gas mold for when concrete is filled, includes gas mold body (1), sets up business turn over pneumatic valve (2) on the gas mold body, cladding in outer demoulding layer (3) outside the gas mold body, the buckle fills gassing gas mold in gas mold body outlying mount (4). When concreting the concrete wall, will the utility model discloses set up in advance in the wall form, but the greatly reduced concrete volume, reduce the concrete member dead weight, reduce construction engineering construction cost.
Description
Technical Field
The utility model belongs to the technical field of the construction appurtenance.
Background
At present, in the construction process of a building site, the novel aluminum alloy template is widely popularized and applied, and when a construction unit carries out structural optimization, part of brick walls which do not play a bearing role are optimized into concrete walls, so that the construction efficiency is improved. However, the concrete wall is only used as a separation space and isolated from the indoor and outdoor space, and has the problems of great weight and high cost compared with brick masonry.
Disclosure of Invention
An object of the utility model is to solve the problem that above-mentioned prior art exists, provide a reducible concrete use amount in the construction, reduce the concrete member dead weight, reduce construction engineering construction cost's a detachable gas mold for when concrete is filled.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a detachable gas mold for when concrete is filled, includes the gas mould body, sets up business turn over pneumatic valve on the gas mould body, cladding in the outer demoulding layer of gas mould body, the card cover is at the peripheral mount of gas mould body.
Further, the air inlet and outlet valve is arranged on one side of the top or the bottom of the air mould body.
Furthermore, the air mould body is cylindrical after being inflated.
Adopt the utility model discloses, can set up the gas mould body in the template that needs the cast concrete wall, occupy certain space in the concrete wall after aerifing to the gas mould body through business turn over pneumatic valve, then cast concrete, reducible concrete use amount between gas mould body and template. After the concrete is solidified and the air is discharged through the air inlet and outlet valve, the air mould body is reduced and separated from the concrete, and the air mould body is effectively isolated from the concrete by the outer demoulding layer, so that demoulding is convenient.
Adopt the utility model discloses, the concrete use amount that can significantly reduce reduces the concrete member dead weight, reduces construction engineering construction cost. The utility model has low manufacturing cost, convenient use and repeated use.
Drawings
Fig. 1 is a schematic diagram of an application example of the present invention;
fig. 2 is a schematic diagram of another application example of the present invention.
Detailed Description
The contents of the present invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 1, the detachable gas mold for concrete filling includes a gas mold body 1, an air inlet and outlet valve 2 disposed at one side of the bottom of the gas mold body, an outer mold release layer 3 covering the gas mold body, and a fixing frame 4 clamped and sleeved on the periphery of the gas mold body. Fig. 2 shows a state where the air inlet/outlet valve 2 is provided on the top of the air mold body. The air mould body 1 can be made into shapes of various sizes and cylindrical shapes after being inflated, and a plurality of air mould bodies can be arranged in a wall side by side. The air mould body is made of rubber or other flexible materials capable of bearing large extrusion force, the outer demoulding layer 3 is coated or moulded on the outer surface of the air mould body, the material which is easy to strip concrete is adopted, and various commercially available demoulding agents or film materials can be used at present. The fixing frame can be a lantern ring structure sleeved on the periphery of the air mould body in a ring mode, and can also be a buckle structure capable of clamping the air mould body.
Adopt the utility model discloses a construction method as follows: the reinforcing steel bars 6 are bound on the inner side of a wall formwork 7 to be poured, the fixing frame 4 is bound and fixed on the reinforcing steel bars through iron wires, then the air mold body 1 is arranged in the fixing frame 4, and the air inlet and outlet air valve 2 is inflated to ensure that the expansion card is stably fixed in the fixing frame. When the business turn over pneumatic valve of air model body was located bottom one side, will set up the air model body in the position that its bottom is located wall form bottom, and air model body bottom area convex chimb 1a, and the chimb of being convenient for of slotting in wall form bottom exposes, and after the concrete of pouring solidifies, unpacks apart the wall form, can take out the air model body from the bottom, as shown in fig. 1. When the air inlet and outlet valve of the air mould body is positioned at the top, the air mould body is arranged at the position, at which the top end of the air mould body is positioned at the top of the wall body, and the air mould body is taken out from the top after the poured concrete is solidified, as shown in figure 2. After the air mould body is arranged, concrete is poured into the inner cavity of the wall form to construct the concrete wall 5. The inflatable air mould body occupies a certain space in the wall body, and the concrete pouring amount is reduced. After the concrete is solidified, the air inlet and outlet valves are used for deflating, the air mould body is shrunk, the outer demoulding layer 3 is stripped from the concrete, and the air mould body is taken out.
