Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of inner membrane template, and particularly relates to a reusable telescopic inner membrane template for empty box and a method. BACKGROUND

[0002] The statements in this section are merely provided to give background information related to the present application and do not necessarily constitute prior art.

[0003] Various foundations are developed along with various buildings. Since the entity foundation is limited in size by the upper structure or equipment, a large cross-sectional size is required, which is very easy to form mass concrete, so that the size of the entity foundation is no longer a bearing capacity control, and the bearing capacity is often far more than the load of the upper structure, so that not only the concrete is wasted, but also the hydration heat problem and the crack problem are easy to form. In the above case, the use of the cavity foundation is an effective way to reduce the consumption of concrete and reduce the cost of the building.

[0004] The inventor finds that the conventional cavity foundation internal template cannot be taken out after pouring, which not only wastes materials, but also easily causes internal pollution and corrosion of the foundation, which is not conducive to the safety of the foundation. SUMMARY

[0005] In order to solve the technical problems in the background art, the present application provides a reusable telescopic inner membrane template for empty box and a method, which can solve the problem of waste of materials caused by the conventional built-in template which cannot be taken out by setting a reusable telescopic cavity inner membrane template.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0007] The first aspect of the present application provides a reusable telescopic inner membrane template for empty box.

[0008] A reusable telescopic inner membrane template for empty box comprises a telescopic framework and an inner membrane; the inner membrane is connected with the telescopic framework and telescopes with the telescopic framework; the inner membrane comprises a first layer of membrane and a second layer of membrane, the first layer of membrane is directly connected with the telescopic framework, and the second layer of membrane is laid on the first layer of membrane, and when the telescopic framework is unfolded, the second layer of membrane is adhered to the concrete in the empty box, and the second layer of membrane is separated from the first layer of membrane.

[0009] As an implementation manner, the telescopic framework is provided with a hook, and the first layer of membrane is connected with the telescopic framework through the hook.

[0010] As an implementation manner, the telescopic framework comprises an inner rod, an outer sleeve rod, a connecting rod, an inclined bracing rod, a vertical bracing rod, a horizontal bracing rod and a sliding sleeve rod.

[0012] As an implementation form, the vertical support rod is connected with the inclined support rod through a sliding sleeve rod.

[0013] As an implementation form, the connecting points among the vertical support rod, the transverse support rod and the inclined support rod are movable nodes.

[0014] As an implementation form, a spring buckle is connected between the end of the inner rod extending out of the outer sleeve rod and the outer sleeve rod.

[0015] As an implementation form, when the transverse support rod is horizontal, the inclined support rod is driven to support the vertical support rod, so that the four inner corner points are right angles and the inner membrane forms a rectangle.

[0016] The second aspect of the present application provides a working method of the reusable telescopic empty box inner membrane template.

[0017] A working method of the reusable telescopic empty box inner membrane template, which comprises:

[0018] When the inner membrane is unfolded, the outer sleeve is pulled upward until the hole of the outer sleeve is clamped at the spring buckle, so that the sleeve is fixed, and at this time, the inner membrane is completely unfolded; when the inner membrane is folded, the spring buckle is pressed, and the outer sleeve is pushed downward until it is completely folded, and then the folded inner membrane is taken out from the reserved hole in the foundation.

[0019] As an implementation form, when in use, the transverse support rod is horizontal, the inclined support rod is driven to support the vertical support rod, so that the four inner corner points are right angles and the inner membrane forms a rectangle.

[0020] As an implementation form, after the inner membrane is extracted, a prefabricated pipe is placed in the foundation, the size of the pipe is equal to the size of the hole, and the height of the pipe is slightly higher than the distance from the bottom surface of the cavity to the inner surface of the foundation.

[0021] After the pipe is placed, concrete is poured into the pipe to the upper surface of the foundation, and then the concrete is solidified.

[0022] The hole after solidification is sealed and forms an integral whole with the surrounding foundation.

[0023] Compared with the prior art, the present application has the following beneficial effects:

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs.

[0034] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, devices, components and / or combinations thereof, but do not preclude the presence or addition of one or more other features, steps, operations, devices, components, and / or combinations thereof.

[0035] Referring to Figures 1-4 The present embodiment provides a reusable telescopic inner membrane template for empty container, which comprises a telescopic skeleton and an inner membrane; the inner membrane is connected with the telescopic skeleton and telescopes with the telescopic skeleton; the inner membrane comprises a first layer membrane and a second layer membrane; the first layer membrane is directly connected with the telescopic skeleton; the second layer membrane is laid on the first layer membrane; when the telescopic skeleton is unfolded, the second layer membrane is adhered with the concrete in the empty container; and the second layer membrane is separated from the first layer membrane.

[0036] In the present embodiment, the first layer membrane can be implemented by using canvas 7, and the second layer membrane can be implemented by using plastic film which is sleeved outside the first layer membrane. The outer plastic film will be expanded with the telescopic skeleton so as to prevent the canvas from being adhered with the concrete. After the concrete is solidified, the inner stainless steel skeleton is contracted, the plastic film is adhered with the concrete, and the canvas only needs to be separated from the plastic film.

[0037] In the specific implementation process, hooks 10 are arranged on the telescopic skeleton, and the first layer membrane is connected with the telescopic skeleton through the hooks 10.

[0038] As shown in Figure 2 and Figure 3 , the telescopic skeleton comprises an inner rod 1, an outer sleeve rod 2, an inclined support rod 6, a vertical support rod 5, a horizontal support rod 3 and a sliding sleeve rod 9.

[0039] One end of the inner rod 1 extends into the inner part of the outer sleeve rod 2 and is connected with a plurality of connecting rods 11 through a spring 8; the other end of the inner rod 1 extends out of the outer sleeve rod 2; the outer sleeve rod 2 is further connected with the horizontal support rod 3, the horizontal support rod 3 is connected with the vertical support rod 5, and the vertical support rod 5 and the horizontal support rod 3 are connected with the inclined support rod 6.

[0040] The vertical support rod 5 is connected with the inclined support rod 6 through the sliding sleeve rod 9.

[0041] The connecting points among the vertical support rod 5, the horizontal support rod 3 and the inclined support rod 6 are movable nodes 4.

[0042] Specifically, a spring buckle 12 is connected between the end of the inner rod 1 extending out of the outer sleeve rod 2 and the outer sleeve rod 2.

[0043] When the transverse support is horizontal, the diagonal support is used to open the vertical support, so that the four inner corners are right angles and the inner membrane forms a rectangle.

[0044] The working method of the reusable telescopic empty box inner membrane template comprises the following steps:

[0045] When the inner membrane is unfolded, the outer sleeve is pulled upwards until the hole of the outer sleeve is clamped in the spring buckle, so that the sleeve is fixed, and at this time the inner membrane is completely unfolded; when the inner membrane is folded, the spring buckle is pressed and the outer sleeve is pushed downwards until it is completely folded, and then the folded inner membrane is taken out from the reserved hole in the foundation.

[0046] When in use, the transverse support is horizontal, the diagonal support is used to open the vertical support, so that the four inner corners are right angles and the inner membrane forms a rectangle.

[0047] After the inner membrane is extracted, the prefabricated pipe is placed in the foundation, the size of the pipe is equal to the size of the hole, and the height of the pipe is slightly higher than the distance from the bottom surface of the cavity to the inner surface of the foundation, so that the concrete can be prevented from leaking out of the pipe during subsequent concrete pouring. After the pipe is placed, concrete is poured into the pipe to the upper surface of the foundation, and then the hole is sealed and integrated with the surrounding foundation after solidification. The column formed by the lower pouring can also improve the bearing capacity and make the foundation more stable.

[0048] The reusable telescopic empty cavity inner membrane template is provided, which solves the problem that the conventional built-in template cannot be taken out and the material is wasted. The reusable telescopic empty box inner membrane template comprises a telescopic framework and an inner membrane. The inner membrane is connected with the telescopic framework and telescopes with the telescopic framework. The technical scheme of the reusable telescopic empty box inner template reduces the cost of multiple pouring of the empty box foundation and avoids corrosion caused by the conventional template remaining in the foundation.

[0049] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
