Description

Concrete wall thickness degree supports uses the inner support sleeve pipe

Technical field

The utility model relates to the location and the fastening devices of construction formwork, relates to concrete wall thickness degree especially and supports with location and fastening devices.

Background technology

At the concrete wall, when being casting reinforced coagulating cement cob wall process, existing method is at many isometric bar reinforcements of the on-the-spot intercepting of cast, then respectively with between iron wire or other elongated bundled pieces across being tied on the reinforced frame, plank is set up at two ends at bar reinforcement, then injects cement concrete and obtain the reinforced cement concrete wall in plank.But preceding method has the following disadvantages: one, be difficult to be consistent in the on-the-spot bar reinforcement length that obtains of cast, the process of intercepting reinforcing bar is pure manual operations, has certain error unavoidably, and finally influences the uniformity and the uniformity of thickness of wall body; Two, the value ratio of bar reinforcement is higher, has increased building costs; When three, being fixed to bar reinforcement on the reinforced frame, need to use bar reinforcement iron wire or other elongated connectors in addition itself, fixation procedure is cumbersome, and efficiency of construction is low.

Also having a kind of mode is to adopt in the template outside it is positioned, but the scale error of the reinforced cement concrete wall of making in this way is bigger, is difficult to reach the quality requirement of construction formwork construction, can't guarantee construction quality.

It is to use elongating screw rod with a kind of reinforcing that runs through the reinforced cement concrete body of wall that a kind of mode is arranged in the prior art again, then with nut location and fixed form, but this mode can be cemented in long bolt in the reinforced cement concrete body of wall simultaneously, causes a large amount of raw-material wastes.

The utility model content

The purpose of this utility model is to provide a kind of concrete wall thickness degree to support and uses the inner support sleeve pipe, to solve the aforementioned problems in the prior.Concrete wall thickness degree in the utility model supports with the inner support sleeve pipe when guaranteeing construction quality, can also save production cost to the full extent and the constructing operation step.

The technical scheme that the utility model provides is as follows:

Concrete wall thickness degree supports and uses the inner support sleeve pipe, comprises a hollow section and two pipe boxes, it is characterized in that:

Be provided with shoulder hole in the pipe box, the hollow section two ends are the macropore of the shoulder hole of two pipe boxes of socket respectively;

The outer middle side part of pipe box forms frustum in shoulder hole aperture one side at a certain angle.

Aforementioned concrete wall thickness degree supports with the inner support sleeve pipe in process of production, only need to prepare the mould of pipe box, then intercept the hollow section of different length, the concrete wall thickness degree that promptly can obtain to adapt to the different length of different needs at hollow section two ends socket pipe box supports uses the inner support sleeve pipe, makes the reinforced cement concrete body of wall of different-thickness then.In use, only need the support of concrete wall thickness degree is positioned in the template with the inner support sleeve pipe, then run through template and inner support sleeve pipe less than shoulder hole aperture, the movable screw rod that interts in pipe box and hollow section with an internal diameter, the nut check of screw rod two ends, then in template, pour cement concrete into, can guarantee that the reinforced cement concrete body of wall is even, consistent; By the time after the reinforced concrete cob wall forms, screw rod and nut all can be pulled down repeated use, further save production cost.

The frustum that forms on pipe box surface can increase the concrete wall and support contact surface frictional force between inner support sleeve pipe and template with thickness.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, and the outer middle side part of pipe box is with 10 ° ^～55 ° angle forms frustum in shoulder hole aperture one side.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, and frustum is inboard to be connected by centrosymmetric brace with the pipe box outside, and brace can be strengthened the intensity of pipe box to a certain extent, and strengthens the contact surface frictional force between pipe box and template.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, and the diameter of frustum is 1.2 of a pipe box shoulder hole hole diameter ^～2 times.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, also comprises screw rod that is movably arranged on hollow section and pipe box inside and the swivel nut that is connected in the screw rod two ends.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, and the shape of hollow section, pipe box and frustum is not limit, and its cross section can be preferably circle for circular, square, triangle or isosceles trapezoid.

Aforementioned concrete wall thickness degree supports with in the inner support sleeve pipe, and hollow section and pipe box all adopt plastics to make, and preferably make with the PVC material.
