Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a beam-free and column-free concrete module for buildings. Background Technology

[0002] Traditional prefabricated concrete shear wall systems typically involve prefabricating all major load-bearing components such as walls, slabs, and beams in a factory and then transporting them to the site for installation. This results in a large number of nodes and complex connections, making it impossible to achieve construction without formwork and supports, and indicating a low level of industrialization.

[0003] With the transformation and upgrading of the construction industry, concrete modules are gradually being used in low-rise and multi-story buildings such as cement houses and farmhouses. However, the existing concrete module structural system is generally formed by overlapping or prefabricated shear wall modules. The module size is limited by the floor slab span and the corner columns protrude, which not only affects the overall aesthetics but also the utilization of interior space. Utility Model Content

[0004] To overcome the above-mentioned technical problems, this utility model provides a beam-free and column-free building concrete module.

[0005] The present invention adopts the following technical solution: A beam-free and column-free concrete module for buildings, comprising: It is formed by integral casting of the top slab and three continuous walls, and the front side of the module has an opening. The wall serves as the side of the module; vertical ribs protrude from the top of the wall, and vertical metal pipes are pre-embedded at the bottom of the wall; internally threaded sleeves are pre-embedded on the open side face and the opposite face of the wall. The top slab serves as the top surface of the module; the side reinforcement of the top slab connected to the wall is anchored into the wall, the front edge of the top slab extends beyond the end face of the wall, and the rear edge of the top slab does not reach the outer wall surface of the wall in the direction it is in. The front and rear ends of the top slab are reserved with post-cast connection grooves, and the reinforcement is exposed in the post-cast connection grooves. The front end and corners of the wall are all edge concealed columns, with a total of four edge concealed columns. The main wall is located between two adjacent edge concealed columns.

[0006] Preferably, each main wall includes: a non-removable template serving as the surface on both the inner and outer sides of the wall; a steel mesh on the inner side of each of the two non-removable templates; an insulation board between the two steel meshes; and diagonal wires between the two steel meshes.

[0007] Preferably, it also includes a base plate, which is cast integrally with the wall as the bottom surface of the module; the edge of the base plate on the opening side does not reach the end face of the wall in the same direction, and the four sides of the base plate have reinforcing bars, with the reinforcing bars on the side where the base plate connects to the wall being bent and anchored in the wall.

[0008] Preferably, the sidewall of the post-cast connection groove on the open side of the top plate is aligned with the edge of the open side of the bottom plate.

[0009] Preferably, the top slab is a prestressed precast slab.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a beam-free and column-free large-space concrete module, including walls and a top slab, which are cast in one piece to form a multi-faceted concrete module; the module adopts a beam-free and column-free structure, using walls to replace traditional beams and columns, avoiding the appearance of protruding beams or columns, making the interior of the module flat and beautiful, and improving the utilization rate of indoor space; the module is provided with an open side to avoid wall-to-wall connections between adjacent modules. 2. Prestressing technology was used to increase the span of the slab, thereby realizing a large space for the module; 3. The module can also be equipped with a base plate for easy integration with interior decoration; 4. The modules are manufactured in the factory with high precision and quality, and the on-site installation is quick and convenient, which greatly shortens the construction period, reduces construction costs, and has good economic and social benefits.

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings. Throughout the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used are commercially available or commonly used in the art. The methods in the embodiments, unless otherwise specified, are conventional methods in the art. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0014] Example 1 Please see Figure 1 In this embodiment, the beam-free and column-free building concrete module is integrally cast from a top plate 1 and three horizontally adjacent C-shaped walls 2. The front of the module is the open side, and there are no walls on the open side. Wall 2 serves as the side of the module; vertical reinforcing bars extend from the top of wall 2, and vertical metal pipes are pre-embedded at the bottom of wall 2. The top reinforcing bars and bottom metal pipes are used to cooperate for the vertical assembly of the module; internal threaded sleeves 21 are pre-embedded at the front and rear relative positions of the opening side of wall 2 for front-to-back connection between modules. The top slab 1, serving as the top surface of the module, is precast using prestressed technology. The left, rear, and right sides of the top slab 1, where it connects to the wall 2, have reinforcing bars anchored to the wall 2. The front edge of the top slab 1 extends beyond the front faces of both walls 2, while the rear edge of the top slab 1 does not reach the rear faces of both walls 2. Post-cast connection grooves 11 are pre-reserved at both the front and rear ends of the top slab 1, with reinforcing bars protruding from the grooves for casting connections between modules, ensuring that the joint between the front and rear top slabs 1 is located at the top of the preceding module's wall 2. The front end and corners of wall 2 are both concealed edge pillars 22, and the section between two concealed edge pillars 22 is the main wall 23. The missing part on the opening side is actually the front main wall 23, such as... Figure 3 , Figure 4 As shown, each main wall 23 includes: two non-removable templates 231 serving as the inner and outer surfaces of the wall, a steel mesh 233 set on the inner side of each of the two non-removable templates 231, an insulation board 232 set between the two steel meshes 233, and a diagonal wire inserted between the two steel meshes 233, and is cast and shaped.

[0015] A type of beam-free and column-free concrete module for building use: Between adjacent modules, the two ends of the wall are connected by internal threaded sleeves 21 combined with steel anchor rings, bolts or steel wire ropes. After the front and rear top plates 1 are spliced, multiple ring bars are placed in the post-pouring connection groove 11 before pouring. Vertically adjacent modules are connected vertically and vertically through metal pipes and steel bars at the top of wall 2. All wall joints or top joints of adjacent concrete modules are filled with grout.

[0016] Example 2 Please see Figure 2 , Figure 6 The difference between this embodiment and Embodiment 1 is that a base plate 3 is also provided. The base plate 3 serves as the bottom surface of the module and is integrally cast with the wall. The front edge of the base plate 3 does not reach the front end face of the left and right walls 2, thus forming a post-cast section 31, which facilitates the casting connection between the base plates 3 when connecting the front and rear modules. The four sides of the base plate 3 have reinforcing bars, and the reinforcing bars on the side where the base plate 3 connects to the wall 2 are bent and anchored inside the wall 2. The front edge of the base plate 3 is vertically aligned with the side wall of the front post-cast connection groove 11 of the top plate 1.
