Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a prefabricated, slotless structure and its construction method. Background Technology

[0002] Prefabricated buildings have been widely used in the construction industry in recent years due to their advantages such as fast construction speed and low environmental pollution. However, traditional prefabricated structures often require a large amount of on-site grooving work during installation to meet the needs of pipeline layout and component connection; This grooving operation not only increases the difficulty and time cost of construction, but may also have an adverse effect on the structural strength of precast components. At present, the industry mainly alleviates this problem by optimizing the design of precast components or using post-pouring strip technology, but these methods still have certain limitations.

[0003] In existing technologies, the following methods are commonly used to solve the grooving problem in prefabricated buildings: First, pre-reserved holes in precast components, i.e., pipeline channels are pre-defined during factory prefabrication. However, this method lacks flexibility and is difficult to adapt to changing on-site needs. Second, on-site grooving, i.e., grooving is performed after installation according to actual needs. However, this method is inefficient and easily damages components. Third, post-pouring strip technology is used, i.e., a post-pouring area is reserved at the connection of precast components, and concrete is poured after the pipeline layout is completed. However, this method has a long construction cycle and is difficult to control in terms of quality. The main drawbacks of existing technologies are: the pre-drilled hole method has poor adaptability and cannot meet the needs of complex and ever-changing pipeline layouts; the on-site trenching method is inefficient and easily damages components; and the post-cast strip technology has a long construction cycle and is difficult to control in terms of quality. These shortcomings seriously restrict the further promotion and application of prefabricated buildings. Therefore, in response to the aforementioned technical problems, a prefabricated, slotless structure and its construction method are proposed. Summary of the Invention

When two sets of precast wall components are on the same straight line, they are connected by a straight connector. When two sets of precast wall components are in a mutually perpendicular position, they are connected by an L-shaped connector. When three sets of walls are connected in a T-shape, they are connected by a T-shaped connector.

[0009] Preferably, the prefabricated wall component has multiple sets of channel connection slots, and the pipeline channel module is inserted into the channel connection slot.

[0013] By adopting the above technical solution, and by using the rapid installation of prefabricated components and pipeline layout in prefabricated buildings, while ensuring the integrity of the structure and construction efficiency, pipelines are laid in the pipeline channel module according to the drawings. First, the pipeline fixing module is adjusted to a suitable installation position. Then, a certain number of pipeline fixing devices of appropriate size are selected according to the size of the pipeline to be connected and the line layout. Multiple sets of pipeline fixing devices are inserted into the adjusting slide groove in sequence.

During the movement, the lifting locking rod uses the compression ball at its bottom to compress multiple sets of locking balls to expand outward in the locking groove.

Compared with existing technologies, this prefabricated, non-grooving structure and its construction method have a reasonable connection structure between the wall top and the ground, a simpler connection process, and a stable connection structure. The connection between the prefabricated wall components and the ground slab is fixed by inserting the foundation steel reinforcement frame into the prefabricated wall components. The connection between the prefabricated wall components and the ground slab is further fixed by injecting concrete into the grouting port.

When two sets of prefabricated wall components are on the same straight line, they are connected by a straight connector. When two sets of prefabricated wall components are in a mutually perpendicular position, they are connected by an L-shaped connector. When three sets of walls are connected in a T-shape, they are connected by a T-shaped connector.

[0019] 2. Compared with existing technologies, this prefabricated, slotless structure and its construction method utilizes the rapid installation of prefabricated components and pipeline layout in prefabricated buildings, while ensuring the integrity of the structure and construction efficiency. Pipelines are laid within the pipeline channel modules according to the drawings. First, the pipeline fixing modules are adjusted to suitable installation positions. Then, a certain number of appropriately sized pipeline fixing devices are selected based on the required pipeline size and route layout.

During the movement, the lifting locking rod compresses multiple sets of locking balls in the locking groove through the extrusion ball at its bottom, causing them to expand outward. As the locking balls expand outward, they lock into the locking groove of the adjusting slide groove, thus completing the fixed connection between the insertion fixing column and the adjusting slide groove.

One end of the pipeline guide module 9 is connected to the arc-shaped slide 81 by an expansion bolt. At this time, the pipeline guide module 9 can slide freely with the expansion bolt at one end of the pipeline guide module 9. The sliding trajectory of the pipeline guide module 9 is the same as the trajectory direction of the arc-shaped slide 81. When it is rotated to a suitable position, the other end of the pipeline guide module 9 can be fixedly connected to the arc-shaped slide 81 by an expansion bolt. Then, according to the size of the pipeline to be connected and the layout of the line, a certain number of pipeline fixing devices 92 of appropriate size are selected, and multiple sets of pipeline fixing devices 92 are inserted into the adjusting slide 91 in sequence. The multiple sets of pipeline fixing devices 92 are slid to maintain a suitable distance, and the pipeline fixing devices 92 can be rotated to a suitable position according to the direction of the pipeline. They are then fixedly connected to the adjusting slide 91 by locking bolts 924. Locking is achieved by turning the locking bolt 924. The locking bolt 924 drives the lifting connecting plate 926 and the lifting locking rod 927 connected to it to move up and down. During the movement, the lifting locking rod 927 compresses multiple sets of locking balls 929 in the locking groove 911 through the extrusion ball 928 at its bottom, causing them to expand outward. As the locking balls 929 expand outward, they snap into the locking groove 911 of the adjusting slide 91, thus completing the fixed connection between the plug-in fixing column 922 and the adjusting slide 91. The pipeline is then sequentially plugged into the pipeline fixing ring 921 of the pipeline fixing device 92. Depending on the type of pipeline, the filling groove 34 can be filled with corresponding heat insulation, sound insulation, and other protective filling materials. One end of the pipeline is connected to the corresponding outlet 33 and socket hole 32, and the other end is connected to the pipeline connector box 31. The pipeline connector box 31 is then plugged into the pipeline channel module 3. Then, according to the drawings, the pipelines are fixedly connected to the bottom of the prefabricated floor slab component 5. The corners and interfaces of the pipelines in the prefabricated floor slab component 5 are all set in the conduit box 7, and the pipelines enter and exit through the pipeline connection holes 71. The number and direction of the openings of the pipeline connection holes 71 in the conduit box 7 are pre-made according to the pipeline layout drawings. The conduit box 7 can be opened through the conduit box cover 72 to facilitate subsequent maintenance work. The conduit box 7 can be divided into two by opening parallel pipeline connection holes 71 or by using a partition to facilitate the staggered layout of water and electrical circuits. After the pipeline layout is completed, the ceiling panel 6 is fastened to the bottom of the prefabricated floor slab component 5, and the pipelines in the prefabricated floor slab component 5 and the pipelines in the pipeline channel module 3 are connected in the pipeline joint box 31. The above is the working principle of this prefabricated prefabricated non-grooving structure and its construction method.
