Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of external wall panel structures, in particular to a kind of light weight rotary external wall panel assembling structure. BACKGROUND

[0002] With the acceleration of urbanization, industrial land resources are increasingly strained, and land costs are rising, so the traditional single-story plant model has been difficult to meet the needs of industrial development. Industrialization is a new industrial carrier space model that actively explores to solve the problems of land shortage and low utilization rate of existing industrial land in the process of rapid economic development in cities.

[0003] Industrialization refers to the vertical space form of traditional single-story flat plant that is gathered into high-rise floors, which helps to solve space problems, improve land use resource utilization, increase economic density, introduce high-end industries and advanced production capacity, provide strong space support for manufacturing, and achieve production and city integration.

[0004] PC external wall panels have broad application prospects in multi-story plants. PC external wall panels use factory prefabrication and on-site assembly, reducing on-site wet work, fast construction speed, effectively shortening the construction period of multi-story plants, and having the advantages of high construction efficiency, reliable quality, energy saving and environmental protection, high design flexibility, and good seismic performance.

[0005] PC external wall panels are generally divided into line connection and point connection, of which line connection is a sliding design, and point connection can use sliding or rotating design. The current rotating design of PC external wall panels uses vertical sliding nodes on the upper and lower sides. This node structure cannot meet the rotational displacement requirements of the external wall panel, and is inconsistent with the requirements of Appendix B of JGJT458-2019 "Application Technology Standard for Prefabricated Concrete External Wall Panel". The horizontal installation error requirement is high, the construction difficulty is large, and the cost is high, which cannot meet the technical standard requirements. UTILITY MODEL CONTENTS

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Example 1:

[0032] like Figures 1-7 As shown in the figure, the arrows indicate the direction of movement. A lightweight rotating external wall panel assembly structure includes an external wall panel 1 and a main structure 2. The external wall panel 1 is connected to the main structure 2 through the second vertical support node 32 at the bottom as a vertical force-bearing node, thereby realizing the transfer of vertical loads.

[0033] The external wall panel 1 is also connected to the main structure 2 through two vertically distributed vertical sliding nodes 4 and two vertically distributed horizontal sliding nodes 5. The lower vertical sliding nodes 4 and vertically distributed horizontal sliding nodes 5 are located on the left and right sides of the second vertical support node 32, respectively. The horizontal force and bending moment in the plane of the external wall panel 1 are borne by the two vertically distributed vertical sliding nodes 4 and transmitted to the main structure 2; the horizontal force and bending moment outside the plane of the external wall panel 1 are jointly borne by the two vertically distributed vertical sliding nodes 4 and two vertically distributed horizontal sliding nodes 5 and transmitted to the main structure 2, thereby improving wind and earthquake resistance.

[0034] The external wall panel 1 is a lightweight, rotating type. The interior of the lightweight, rotating external wall panel 1 is filled with extruded polystyrene board 11, which is a lightweight material.

[0035] The lightweight rotating external wall panel 1 is internally reinforced with prestressed steel bars 12 as required, which serves as a crack-resistant measure during hoisting. This improves the strength of the external wall panel 1, reduces cracks, and enhances its stress and crack resistance during processing, transportation, installation, and use, thus meeting actual building requirements.

[0036] Both the first vertical support node 31 and the second vertical support node 32 include a bracket 33 connected to the outer wall panel 1. The bracket 33 is provided with an adjusting embedded part 34 or a first shim connected to the main structure 2. The vertical load is borne by the bracket 33, and the elevation of the outer wall panel 1 is adjusted by adjusting the embedded part 34 or the first shim during installation.

[0037] The vertical sliding node 4 includes a connector 41 that is connected to the outer wall panel 1 and the main structure 2 respectively, and the connector 41 is provided with a connecting embedded part 42 that extends into the outer wall panel 1.

[0038] The connector 41 includes an angle steel 411 that is connected to the outer wall panel 1 and the main structure 2 respectively.

[0041] In Example 1, the external wall panel 1 is 12 meters high and 2.25 meters wide. Using internally filled extruded polystyrene board 11 and prestressed steel bars 12 reduces its weight by 30%, resulting in significant lightweighting. The bottom of the external wall panel 1 uses a second vertical support node 32 as a vertical load-bearing node. This node allows for adjustment of the elevation of the external wall panel 1 during temporary installation, and once adjusted, it can be used as a node for operational use.

[0042] Both vertical sliding nodes 4, distributed vertically, are provided with vertical elongated holes 414. Anchor bolts 422 pass through the elongated holes 414 and are connected to connectors 41, enabling vertical sliding and bearing the horizontal forces and bending moments in the plane of the external wall panel 1. The two vertical horizontal sliding nodes 5, distributed vertically, can slide vertically and horizontally respectively through connecting bolts 53, cooperating with the two vertical sliding nodes 4 to jointly bear the horizontal forces and bending moments in the plane of the external wall panel 1.

[0043] The design of the external wall panel 1 node in Example 1 makes the stress of each node simple and clear, simplifies the design and construction of the node, reduces the complexity of design and construction, improves construction efficiency and saves costs.

[0044] The construction process of Example 1 is as follows:

[0046] (2) Hoist the prefabricated exterior wall panel 1 of this floor, align it with the plane position of the second vertical support node 32 and adjust the elevation;
