Problems solved by technology

[0002] Due to structural design requirements, the post-settlement pouring belt can only be closed after the main structure is capped and the settlement is stable. However, construction projects often require pre-sale of closed demonstration areas or outdoor overall interspersed efficiency improvement requirements. The post-settlement pouring belt is closed in advance and the demonstration is completed in advance In the past, the common construction method was to lay cover plates on both sides of the post-pouring belt, then carry out waterproof and protective layer construction, and backfill soil. After the main structure is capped and settled, the overall excavation For the pouring belt part, remove the waterproof layer and cover plate of the pouring belt part, clean the post-casting belt, re-form the concrete, construct the waterproof layer and protective layer, and backfill the soil. The conventional method is cumbersome, repeated operations, time-consuming Higher, the present invention proposes a kind of new solution for above problem

Embodiment 1

[0029] see Figure 1-3 , a closed structure used in the building construction process and its construction technology, including a steel plate 4, a steel pipe is arranged on the steel plate 4, and a pouring hole is arranged on the steel pipe, and the lower surface of the steel plate 4 is sequentially provided with automatic The dense concrete 3 and the post-casting belt formwork 2, the upper surface of the self-compacting concrete 3 is connected with the steel plate 4, and the lower surface is connected with the post-casting belt formwork 2, and the upper surface of the steel plate 4 is provided with a protective component.

[0030] In this embodiment, in order to better use the protective assembly, the protective assembly is sequentially connected with extruded board 5, waterproof membrane 6, isolation layer 7, fine stone concrete rigid protective layer 8 and backfill soil 9 from bottom to top, The lower surface of the extruded board 5 is connected to the steel plate 4, so th...

Embodiment 2

[0036] A construction technique for a closed structure applied in a building construction process, characterized in that it comprises the following steps:

[0037] Step 1: Prepare various raw materials: steel pipe, post-casting strip formwork 2, self-compacting concrete 3 (micro-expansion), steel plate 4, extruded board 5, waterproof membrane 6, isolation layer 7, fine stone concrete rigid protective layer 8, Backfill soil 9, glass fiber bag 10, plastic cloth 11, basement roof 12 and cement mortar 13;

[0038] Step 2: Lay the steel plate 4 on the upper side of the post-casting strip formwork 2, and use cement mortar 13 on both sides of the steel plate 4 to level the slope, so as to construct the waterproof coiled material 6 and the protective layer;

[0039] Step 3: The upper side of the formwork of the post-pouring belt of the floor slab is covered with a steel plate, and holes are reserved on the steel plate, and then the steel pipe and the steel plate 4 are welded together ...

Embodiment 3

[0046] On the basis of Example 2, when the closed structure of the present invention is in use, the upper side of the post-casting belt of the floor is covered with a steel plate 4, and holes are reserved on the steel plate 4, and then the steel pipe and the steel plate 4 are welded together. A steel pipe pouring hole 1 is formed. The waterproof layer and protective layer are constructed simultaneously with the overall structure, the steel pipe pouring hole 1 is filled with glass fiber bag 10 and plastic cloth 11 for protection, and the backfill soil 9 is constructed; after the structure settles stably, self-compacting concrete 3 can be poured from the steel pipe pouring hole 1 (micro expansion).

[0047]The post-cast tape formwork 2 used must be disconnected from the large-area formwork and support, and the support must be provided with relatively independent horizontal braces, vertical poles and scissors braces; The support does not move, and before closing the construction...

Abstract

The invention relates to a closed structure applied to building construction process and a construction process thereof. The closed structure comprises a steel plate, a steel pipe is arranged on the steel plate, a pouring hole is formed in the steel pipe, self-compacting concrete and a post-pouring belt formwork are sequentially arranged on the lower surface of the steel plate from top to bottom,the upper surface of the self-compacting concrete is connected with the steel plate, and the lower surface of the self-compacting concrete is connected with the post-pouring belt formwork; and a protection assembly is arranged on the upper surface of the steel plate. According to the closed structure applied to building construction process, the synchronous construction of an outdoor assembly anda main body structure can be ensured, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of building construction, and relates to an early sealing construction technology of a pouring belt after settlement, and more specifically, to a closed structure and a construction process applied in the building construction process. Background technique [0002] Due to structural design requirements, the post-settlement pouring belt can only be closed after the main structure is capped and the settlement is stable. However, construction projects often require pre-sale of closed demonstration areas or outdoor overall interspersed efficiency improvement requirements. The post-settlement pouring belt is closed in advance and the demonstration is completed in advance In the past, the common construction method was to lay cover plates on both sides of the post-pouring belt, then carry out waterproof and protective layer construction, and backfill soil. After the main structure is capped and settled, the overall...
