Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to energy-saving structures for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. The installation of walls and columns in prefabricated buildings is usually done by first hoisting them into place, then connecting them to the bottom steel bars through sleeves inside the walls and columns, and finally tightening the sleeves and steel bars by pouring cement mortar, thus realizing the installation connection of walls and columns. The connection is quick and convenient.

[0003] However, during the installation and connection process, there are issues with the rebar and sleeve not easily aligning. Workers need to use a reflector to check if the rebar and sleeve are aligned, resulting in low installation efficiency. At the same time, the connection between the rebar and sleeve is not strong enough, leading to poor seismic performance of the building.

[0004] Therefore, we proposed that prefabricated building energy-saving structures can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving structure for prefabricated buildings to solve the problems mentioned in the background art, such as the difficulty in aligning the steel bars and sleeves during the installation process, requiring workers to use a reflector to check whether the steel bars and sleeves are aligned, resulting in low installation efficiency. At the same time, the connection between the steel bars and sleeves is not firm enough, resulting in poor seismic performance of the building.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building energy-saving structure, including wall panels and building keel, wherein curtain wall corner brackets are fixed at equal intervals on the back of the wall panels, and threaded holes and positioning grooves are respectively opened on the top and right side of the building keel; further comprising: a positioning rod is fixedly connected to the side of the curtain wall corner bracket away from the wall panel, and a fixing hole is opened inside the positioning rod; a rubber strip is adhered to the side of the curtain wall corner bracket away from the wall panel; a fixing bolt is threadedly connected inside the threaded hole; a mating block is fixed to the top and right side of the wall panel, and a mating groove is opened on the bottom and left side of the wall panel.

[0007] Preferably, the curtain wall corner bracket is L-shaped, the positioning rod and the positioning groove are connected by an insertion, and the fixing hole and the threaded hole on the positioning rod are positioned corresponding to each other.

[0008] Preferably, the docking block and the docking groove are interlocked, and adjacent wall panels are quickly spliced ​​together through the docking block and the docking groove.

[0009] Preferably, the inner wall of the mating block is symmetrically provided with deep grooves, and the inner wall of the deep groove is slidably connected with a limiting block. A return spring is installed between the end of the limiting block and the inner wall of the deep groove. The inner wall of the wall panel is symmetrically provided with limiting grooves about the center point of the mating groove.

[0010] Preferably, the side of the limiting block away from the reset spring is inclined, and the limiting block corresponds to the position of the limiting groove.

[0011] Preferably, each of the wall panels has a gypsum board inside, and an air layer is provided between two gypsum boards inside the wall panel.

[0012] Preferably, the interior of the air layer is filled with rock wool.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the energy-saving structure of this prefabricated building adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The wall panel is inserted into the positioning groove on the building keel through the positioning rod on the curtain wall corner bracket, so as to realize the quick docking and installation of the wall panel and the building keel. Then, the fixing bolt is screwed into the threaded hole with a tool. At the same time, the fixing bolt passes through the fixing hole on the positioning rod and limits and fixes it. At the same time, the positioning rod is axially limited by the cooperation of the fixing bolt head and the nut. The wall panel, curtain wall corner bracket and building keel are firmly locked into a whole, which can significantly improve the installation efficiency and ensure the connection accuracy. Furthermore, the rubber strip set at the connection part of the curtain wall corner bracket and the building keel can absorb the displacement caused by installation error, structural deformation or external load, and avoid direct rigid collision between the curtain wall corner bracket and the building keel, so as to achieve the purpose of buffering and shock absorption.

[0015] (2) By setting two gypsum boards and an air layer inside the wall panel, and filling the air layer with rock wool, the porous structure of rock wool can absorb high-frequency sound waves, and together with the gypsum board to block low frequencies, a composite sound insulation system is formed, thereby improving the sound insulation effect of the wall panel.

[0016] (3) Adjacent wall panels are quickly assembled by inserting the mating block into the mating groove. At the same time, the limiting block is squeezed and retracts into the mating block. As the mating block extends in, the position of the limiting block corresponds to the position of the limiting groove, so that the limiting block is reset under the elastic force of the reset spring and inserted into the limiting groove, which can limit the mating block, thereby limiting the mating block in the horizontal and vertical directions to prevent misalignment or separation between wall panels.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 This utility model provides the following technical solution: prefabricated building energy-saving structure;

[0027] Example 1: To address the issue in existing technologies where it's difficult to align the reinforcing bars and sleeves during installation, requiring workers to use a reflector to check alignment, leading to low installation efficiency, and the connection between the reinforcing bars and sleeves being insufficiently secure, resulting in poor seismic performance of the building, the following solution is disclosed. Please refer to the following for details. Figure 3 , Figure 5 and Figure 6As shown, the structure includes a wall panel 1 and a building keel 4. Curtain wall corner brackets 5 are fixed at equal intervals on the back of the wall panel 1. Threaded holes 7 and positioning grooves 8 are respectively opened on the top and right side of the building keel 4. The structure also includes: a positioning rod 6 is fixedly connected to the side of the curtain wall corner bracket 5 away from the wall panel 1, and a fixing hole is opened inside the positioning rod 6. A rubber strip 9 is glued to the side of the curtain wall corner bracket 5 away from the wall panel 1. A fixing bolt 15 is threadedly connected inside the threaded hole 7. The curtain wall corner bracket 5 is set in an "L" shape. The positioning rod 6 and the positioning groove 8 are connected by an insertion. The fixing hole on the positioning rod 6 corresponds to the position of the threaded hole 7.

[0028] During the installation of wall panel 1, the positioning rod 6 on the curtain wall corner bracket 5 is first aligned with the pre-set positioning groove 8 of the building keel 4. Initial positioning is completed by vertical insertion, enabling quick connection between wall panel 1 and building keel 4. Subsequently, the staff uses a special tool to screw the fixing bolt 15 into the threaded hole 7, so that the body of the fixing bolt 15 passes through the fixing hole on the positioning rod 6 and the corresponding through hole on the building keel 4. Through the cooperation of the head of the fixing bolt 15 and the nut, the positioning rod 6 is axially limited. At the same time, the fastening force of the threaded connection is used to firmly lock the wall panel 1, the curtain wall corner bracket 5 and the building keel 4 into a whole, which can significantly improve the installation efficiency and ensure the connection accuracy.

[0029] Example 2: Unlike Example 1, this example utilizes the insertion of the mating block 3 into the mating groove 2 to achieve rapid splicing between adjacent wall panels 1. See details... Figures 1-5 and Figure 7 As shown, the top and right sides of the wall panel 1 are fixed with connecting blocks 3, and the bottom and left sides of the wall panel 1 are provided with connecting grooves 2. The connecting blocks 3 and the connecting grooves 2 are connected by a snap-fit ​​connection. Adjacent wall panels 1 can be quickly spliced ​​together by connecting blocks 3 and connecting grooves 2. The interior of the connecting blocks 3 is symmetrically provided with deep grooves, and the inner wall of the deep groove is slidably connected with a limiting block 12. A return spring 13 is installed between the end of the limiting block 12 and the inner wall of the deep groove. The interior of the wall panel 1 is symmetrically provided with limiting grooves 14 about the center point of the connecting grooves 2. The side of the limiting block 12 away from the return spring 13 is inclined, and the positions of the limiting block 12 and the limiting groove 14 correspond to each other.

[0030] When assembling adjacent wall panels 1, first align the mating block 3 of one side wall panel 1 with the mating groove 2 of the other side wall panel 1, and push it horizontally to insert the mating block 3 into the mating groove 2. During the insertion process, the inner wall of the mating groove 2 presses the limiting block 12 on the mating block 3, causing it to overcome the elastic force of the return spring 13 and retract into the mating block 3. When the mating block 3 is fully extended into the predetermined position of the mating groove 2, the limiting block 12 and the limiting groove 14 on the wall of the mating groove 2 are axially aligned. At this time, the return spring 13 releases its elastic force, pushing the limiting block 12 to pop out quickly and embed into the limiting groove 14, thereby limiting the mating block 3 horizontally and vertically to prevent misalignment or separation between the wall panels 1.

[0031] Example 3: Unlike Example 2, this example utilizes two gypsum boards 11 and rock wool within the air layer 10 to improve the sound insulation effect of the wall panel 1. See details for further information. Figure 1 and Figure 5 As shown, each wall panel 1 is provided with a gypsum board 11 inside, and an air layer 10 is provided between two gypsum boards 11 inside the wall panel 1. The air layer 10 is filled with rock wool.

[0032] The wall panel 1 adopts a double-layer gypsum board 11 sandwich structure, forming an air layer 10 in the middle and filled with rock wool material. The rock wool filled in the air layer 10 has a rich fibrous porous structure. When high-frequency sound waves are incident, the sound waves undergo multiple reflections, refractions and frictions in the pores. The sound energy is converted into heat energy and consumed through viscous resistance, thus achieving high-frequency noise attenuation. At the same time, the thick gypsum boards 11 on both sides form a mass inertial barrier to low-frequency sound waves. Thus, the porous structure of the rock wool can absorb high-frequency sound waves, and together with the gypsum board 11 to block low frequencies, a composite sound insulation system is formed, thereby improving the sound insulation effect of the wall panel 1.
