Description

Technical Field

[0001] The utility model belongs to the technical field of building prefabricated components, and in particular relates to a prefabricated assembled combined structural plate group and a building structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Most of the current prefabricated components are large structures, mainly including steel bars and concrete. The steel bars in large structures need to be extended outward, overlapped and tied with the steel bars of other structures, and finally cast to form a connection node. However, for some small-scale and highly flexible construction projects, the connection form of large structures limits the size of the components themselves, and is not conducive to installation and operation, and cannot be applied to such scenarios. Utility Model Content

[0004] The utility model aims to provide a prefabricated assembled composite structural plate group and a building structure, which solves the problem of the applicability of prefabricated components in small-scale and highly flexible construction projects.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A prefabricated assembled composite structural panel group includes prefabricated transverse panels and longitudinal panels, wherein the upper end surface and / or the lower end surface of the transverse panels are provided with horizontal transverse panel joints, the left end surface and / or the right end surface of the transverse panels are provided with vertical transverse panel joints, the upper end surface and / or the lower end surface of the longitudinal panels are provided with horizontal longitudinal panel joints located at the front and rear, and the left end surface and / or the right end surface of the longitudinal panels are provided with vertical longitudinal panel joints located at the front and rear.

[0007] Furthermore, the transverse plate and the longitudinal plate are both rectangular parallelepiped structures.

[0008] Furthermore, at least one of the horizontal joints of the transverse plates and the horizontal joints of the longitudinal plates is provided with a protruding steel bar seat.

[0009] Furthermore, the steel bar seat is a U-shaped structure with an opening facing outward.

[0010] Furthermore, at least one of the horizontal seams of the transverse boards, the vertical seams of the transverse boards, and the vertical seams of the longitudinal boards includes a right-angle segment and an obtuse-angle segment.

[0011] Furthermore, the right-angle sections are located at both ends and the middle of the joint, and the obtuse-angle sections are located between the two ends and the middle.

[0012] Furthermore, the upper end surface and / or the lower end surface of the longitudinal plate are provided with longitudinal plate horizontal through grooves located at the front and rear.

[0013] A building structure adopts the above-mentioned prefabricated assembled composite structural plate group, the horizontal joints of the transverse plates or the horizontal joints of the longitudinal plates are opposite to the adjacent horizontal joints of the transverse plates or the horizontal joints of the longitudinal plates and are cast connected, the vertical joints of the transverse plates or the vertical joints of the longitudinal plates are opposite to the adjacent vertical joints of the transverse plates or the vertical joints of the longitudinal plates and are cast connected, and steel bars are arranged in the horizontal joints and / or the vertical joints.

[0014] Furthermore, the transverse plate is arranged with a front and a rear surface, and the longitudinal plate is arranged between the transverse plates on the front and the rear surfaces.

[0015] Furthermore, the transverse plates and longitudinal plates are arranged in layers, a longitudinal plate is arranged between two adjacent transverse plates in each layer, the transverse plates and longitudinal plates of the upper and lower layers are arranged in a staggered manner, and steel bars are arranged in the horizontal joints.

[0016] Beneficial effects of the utility model:

[0017] (1) By using joints and concrete pouring instead of traditional steel bar binding and concrete pouring, the size and design of prefabricated components are more flexible and can meet the requirements of small size. Under the condition that the connection strength meets the standard, it can also adapt to large-scale construction.

[0018] (2) The joint structure reduces the difficulty of prefabricated component production and facilitates factory processing and formwork production. It only requires internal steel bar binding without considering the leakage of steel bars and the opening of formwork.

[0019] (3) Steel bars are laid in the joints and combined with concrete to achieve connection between the joints, which has reliable connection strength, ensures stable connection between panels, and ensures construction quality.

[0020] The aforementioned main scheme of the utility model and its further options can be freely combined to form multiple schemes, all of which are schemes that can be adopted and protected by the utility model; and in the utility model, (non-conflicting options) options and other options can also be freely combined. After understanding this scheme, those skilled in the art can understand that there are many combinations based on the existing technology and common knowledge, all of which are technical schemes to be protected by the utility model, and they are not exhaustively listed here.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0028] Example 1

[0029] refer to Figure 1 and Figure 2 As shown, a prefabricated assembled composite structural plate group includes a prefabricated transverse plate 1 and a prefabricated longitudinal plate 2. The transverse plate 1 and the longitudinal plate 2 are both rectangular parallelepiped structures and are components cast with reinforced concrete.

[0030] The upper end surface and / or the lower end surface of the transverse plate 1 is provided with a transverse plate horizontal joint 101 (transverse), and the upper end surface and / or the lower end surface of the longitudinal plate 2 is provided with a longitudinal plate horizontal joint 201 (transverse) located in the front and rear. The transverse plate horizontal joint 101 and the longitudinal plate horizontal joint 201 are opposed to each other up and down, and concrete is poured to realize the connection between the upper and lower components. The upper and lower components can be the connection between the transverse plates 1 and the transverse plates 1, the connection between the longitudinal plates 2 and the longitudinal plates 2, or the connection between the transverse plates 1 and the longitudinal plates 2.

[0031] The left end face and / or the right end face of the transverse plate 1 is provided with a transverse plate vertical joint 102, and the left end face and / or the right end face of the longitudinal plate 2 is provided with a longitudinal plate vertical joint 202 located in front and behind. The transverse plate vertical joint 102 and the longitudinal plate vertical joint 202 are opposite to each other on the left and right, and concrete is poured to realize the connection between the left and right components. The left and right components can be the connection between the transverse plates 1 and the transverse plates 1, the connection between the longitudinal plates 2 and the longitudinal plates 2, or the connection between the transverse plates 1 and the longitudinal plates 2.

[0032] Since the span of the building structure formed by the final assembly of the structural panel group is limited, no joints are required on the end faces at the outermost edges to ensure the flatness of the end faces, reduce the operations during prefabrication, reduce the cost of prefabrication, and have good aesthetics.

[0033] In order to improve the connection strength at the joint position, steel bars wrapped in concrete are arranged in the joint. A protruding steel bar seat 301 is provided in at least one of the horizontal joints 101 of the transverse plate and the horizontal joints 201 of the longitudinal plate. The steel bar seat 301 is a U-shaped structure with an opening facing outward. The steel bar seat 301 is used to support and limit the steel bar to avoid displacement of the steel bar during the pouring of concrete.

[0034] At least one of the horizontal joints 101 of the transverse plate, the vertical joints 102 of the transverse plate, and the vertical joints 202 of the longitudinal plate includes a right angle section 302 and an obtuse angle section 303. The joints are long strip-shaped grooves, the cross section of the right angle section 302 is U-shaped, and the cross section of the obtuse angle section 303 is an inverted isosceles trapezoid. The joints of the right angle section 302 ensure the butt support of the upper and lower plates, and the joints of the obtuse angle section 303 ensure more concrete pouring space.

[0035] The right angle sections 302 are located at both ends and the middle of the joint to ensure the accuracy and stability of the connection position, and the obtuse angle sections 303 are located between the two ends and the middle to ensure the reliability and firmness of the joint connection. In addition, the right angle sections 302 and the obtuse angle sections 303 have the same bottom width, and this staggered arrangement forms a concave-convex structure of the concrete itself, further improving the connection support effect of the concrete.

[0036] The upper end surface and / or the lower end surface of the longitudinal plate 2 are provided with longitudinal plate horizontal through grooves 203 located at the front and rear. The longitudinal plate horizontal through grooves 203 are U-shaped in cross section and are used for the subsequent installation and layout of pipelines.

[0040] The above description does not limit the connection layout form of the transverse plate 1 and the longitudinal plate 2, and they can be assembled and combined into any structural form as needed, but their connection nodes still adopt the form of joint casting concrete.

[0041] refer to Figure 3 , Figure 4 and Figure 5As shown, this embodiment defines a specific connection layout form. The transverse plate 1 is arranged with two front and rear surfaces, and the longitudinal plate 2 is arranged between the transverse plates 1 on the front and rear surfaces. At the same time, the transverse plates 1 and the longitudinal plates 2 are arranged in layers in the vertical direction. A longitudinal plate 2 is arranged between two adjacent transverse plates 1 in each layer, and the transverse plates 1 and longitudinal plates 2 of the upper and lower layers are arranged in a staggered manner, and steel bars are arranged in the horizontal joints.

[0042] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.
