Problems solved by technology

[0002] At present, the side wall structure is mostly constructed with cast-in-place reinforced concrete. The construction environment is poor, the process is complicated, and the speed is slow. It is greatly affected by various weather and climate, and the construction quality is difficult to guarantee due to various factors. A lot of abandoned construction waste is a waste of resources and pollutes the environment

Embodiment 1

[0030] See figure 1 with figure 2 The embodiment of the present invention provides a connection node of a prefabricated assembled structure comprising a lower concrete structure 1 and an upper concrete prefabricating member 2 at the upper end of the lower concrete structure 1, and there is more vertical direction of the upper horizontal longitudinal direction of the upper concrete prefabricated member 2. A first connecting member 3, the top of the lower concrete structure 1 is provided with a plurality of second connecting members 4 in a horizontal longitudinal direction, and a plurality of first connectors 3 at the bottom of the upper concrete preform corresponding to the detachable fixed connection. Used to achieve a connection between the vertical direction between the upper concrete prefabricating member 2 and the lower concrete structure 1.

[0031] Further, the upper end of the upper concrete prefabricated member 2 is poured between the top of the lower concrete structure 1....

Embodiment 2

[0045] See image 3 The first connecting plate 5, the second connecting plate 6 of the present embodiment, each including a motherboard, and a bolt hole is spaced apart from the vertical direction; the first connecting plate 5, the second connecting plate 6 also includes a bottom plate. The bottom plate is horizontally, the motherboard is fixed vertically on the bottom plate; the embedded assembly includes a vertical anchor 10 extending in the vertical direction, the anchor being fixed to the bottom plate. The anchor is located on both sides of the bottom plate and the motherboard, respectively; a plurality of anchors are fixed on each bottom plate. The anchor is fixed vertically on the bottom plate. The bottom plate is embedded in the upper concrete prefabricating member 2 or the lower concrete structure 1. The secondary plate 9 is fixed between the two main boards disposed along the horizontal longitudinal interval in the motherboard of the first connector 3 or the second connect...

Embodiment 3

[0047] See Figure 1 to 6 In this embodiment, the present embodiment discloses a prefabricated assembled structure, including a plurality of upper concrete prefabricated members 2, which are sequentially stitched in the lower concrete structure 1, and adjacent two upper concrete prefabricated members 2 longitudinal splicing end surface卯 合 合,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

[0048] The lower concrete structure 1 of the present embodiment is a prefabricated concrete or cast-in-situ.

[0049] The lower concrete structure 1 may be sequentially stitched along the longitudinal direction of the plurality of lower concrete prefabricates, and the splicing structure can be the same as the splicing structure of the plurality of upper concrete prefabricated members 2.

[0050] Further, the longitudinal splicing end face of the two adjacent upper concrete preform members 2 should be fixedly fixed, and the third connecting plate 11 is provided with a bolt via, and the portrait of the two adj...

Abstract

The invention relates to a prefabricated structure and a connecting joint of the prefabricated structure. The connecting joint of the prefabricated structure comprises a lower concrete structure and an upper concrete prefabricated component located at the upper end of the lower concrete structure; a plurality of first connecting pieces are arranged at the bottom of the upper concrete prefabricated component in the horizontal longitudinal direction; and a plurality of second connecting pieces are arranged at the top of the lower concrete structure in the horizontal longitudinal direction, detachably and fixedly connected with the multiple first connecting pieces at the bottom of the upper concrete prefabricated component correspondingly and used for achieving connection between the upper concrete prefabricated component and the lower concrete structure in the vertical direction. The prefabricated structure comprises the lower concrete structure and the multiple upper concrete prefabricated components sequentially spliced in the longitudinal direction of the lower concrete structure. The longitudinal splicing end faces of every two adjacent upper concrete prefabricated components are connected in a mortise and tenon fit mode. The site construction efficiency is high, the construction period can be effectively shortened, and the integrity and building quality of the prefabricated structure can be improved.

Description

Technical field [0001] The present invention belongs to the field of construction engineering, and is specifically related to a prefabricated assembled structure and a prefabricated assembly structure. Background technique [0002] At present, the surface wall structure is mostly used in place-in-place render, the construction work is poor, the process is complex, the speed is slow, subject to various weather, and the quality of the climate, the construction quality is difficult to guarantee, while producing during construction A lot of abandoned construction waste is wasting resources and pollutes the environment. [0003] In order to solve the problem of current casting, the assembly structure is now used, and the prefabricated components are transported to the site to assemble, improve the efficiency of construction work and the quality of the components. Therefore, it is urgent to design a prefabricated assembled structure and a prefabricated assembly structure to implement t...
