Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to an assembled building structure. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled on site using prefabricated parts and components. This construction method has many advantages, such as fast construction speed, labor saving, and improved project quality. Therefore, it has been strongly supported by the country and has become an important direction for the development of my country's construction industry.

[0003] The existing prefabricated building structure requires a large number of bolts and nuts when assembling two prefabricated walls, which is very troublesome to assemble and has low assembly efficiency. In addition, a lot of time will be wasted in the subsequent disassembly process, which greatly affects the work efficiency of the staff.

[0004] Based on the above problems, the utility model provides an assembled building structure. When assembling two building walls, this structure does not require the use of a large number of bolts and nuts. The assembly is very convenient, and when disassembling later, the connection between the two building walls can be released by simply turning the nut counterclockwise, thereby greatly improving the work efficiency of the staff. Summary of the invention

[0005] The technical problem to be solved by the utility model is to design an assembled building structure, which can quickly assemble and disassemble two building walls, thereby improving the work efficiency of staff.

[0006] In order to solve the above technical problems, the prefabricated building structure of the utility model includes a positioning frame and two building walls arranged in parallel. Its structural feature is that the sides of the two building walls close to each other are both provided with rectangular grooves in the height direction, and the two rectangular grooves are relatively arranged to form a cavity compatible with the positioning frame. The positioning frame is inserted into the interior of the cavity, and a first slider that can slide up and down is installed inside the positioning frame. Two limit assemblies are symmetrically connected to the left and right sides of the first slider. The limit assembly includes a support plate fixedly connected to the interior of the positioning frame, and also includes two second sliders connected to the support plate that can move forward and backward. When the first slider moves downward, the two second sliders move in directions away from each other respectively, and when the first slider moves upward, the two second sliders move in directions close to each other respectively. The outer sides of the two second sliders are both fixedly connected with horizontally arranged limit columns, and through holes and limit holes compatible with the limit columns are respectively opened on the positioning frame and the two building walls, and the through holes correspond to the limit holes one by one.

[0007] By adopting the above structure, when assembling two building walls, the two building walls are first aligned and spliced ​​together and the positioning frame is clamped in the cavity formed by the two building walls. When the first slider and the pressure plate move downward, the two second sliders can be driven to move horizontally in the direction away from each other. The movement of the two second sliders can respectively drive the two limit columns to move accordingly, so that the limit columns will pass through the through holes and be inserted into the inside of the limit holes. At this time, the two building walls can be assembled together, and the entire assembly process can greatly improve the work efficiency of the staff.

[0008] Preferably, the two second sliding blocks have mutually adjacent sides which are oppositely arranged inclined surfaces, and the two inclined surfaces are arranged to tilt outward from bottom to top. Through the arrangement of the two inclined surfaces, the two inclined surfaces can move away from each other when subjected to downward pressure.

[0009] Preferably, the bottom surfaces of the two second sliders are fixedly connected with rectangular plates, and the two rectangular plates are connected by a return spring. The horizontal movement of the two second sliders in the direction away from each other will stretch the return spring, so that when the pressure plate moves upward, the return spring will pull the two second sliders to move horizontally in the direction close to each other.

[0010] Preferably, the bottom of the two rectangular plates are both equipped with protrusions, and the upper surface of the support plate is provided with a slide groove adapted to the two protrusions, and the two protrusions can slide back and forth in the slide groove. The matching arrangement of the protrusion and the slide groove facilitates the forward and backward movement of the limit assembly.

[0011] Preferably, the first sliding block is also fixedly connected with a pressing plate, and the pressing plate abuts against the inner sides of the two second sliding blocks.

[0012] Preferably, the pressing plate is in an inverted trapezoidal shape, and the front and rear sides of the pressing plate are respectively provided with two side surfaces adapted to the two inclined surfaces on the two second sliders, and the front and rear side surfaces of the pressing plate are respectively in contact with the two inclined surfaces on the two second sliders. The movement of the first slider can drive the pressing plate to move accordingly, and since the two side surfaces of the pressing plate are in contact with the two inclined surfaces on the two second sliders, when the pressing plate moves downward, it can drive the two second sliders to move horizontally in a direction away from each other.

[0013] Preferably, a vertically arranged screw rod is rotatably installed inside the positioning frame, a vertically arranged threaded hole is provided on the first slider, the first slider is threadedly connected to the screw rod through the threaded hole, and a nut is fixedly connected to the top of the screw rod. By screwing the nut forward, the first slider can be driven to move vertically downward along the nut, and by screwing the nut backward, the first slider can be driven to move vertically upward along the nut.

[0014] Preferably, a plurality of first sliding blocks are arranged in the positioning frame from top to bottom, and a plurality of the limiting components are also arranged accordingly. The arrangement of the plurality of first sliding blocks and the limiting components makes the connection between the two building walls more stable.

[0015] To sum up, the beneficial effect of the utility model is that when assembling two building walls, it is only necessary to clamp the positioning frame in the cavity formed by the two building walls, and then screw the nut forward to assemble the two building walls together. The whole process does not require the use of a large number of bolts and nuts, and the assembly is very convenient. When disassembling later, it is only necessary to screw the nut counterclockwise to release the connection between the two building walls, thereby greatly improving the work efficiency of the staff.

[0027] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0028] See attached Figure 1 The utility model discloses an assembled building structure, which comprises a positioning frame 3 and two building walls 1 arranged in parallel. Figure 2 As shown, the two sides of the building wall 1 close to each other are both provided with rectangular grooves 2 along the height direction, and the two rectangular grooves 2 are arranged opposite to each other to form a cavity adapted to the positioning frame 3, and the positioning frame 3 is inserted into the interior of the cavity, as shown in FIG. Figure 3 and Figure 5 As shown, a first slider 4 capable of sliding up and down is installed inside the positioning frame 3, and two limit assemblies are symmetrically connected to the left and right sides of the first slider 4. The limit assemblies include a support plate 5 fixedly connected to the inside of the positioning frame 3, the support plate 5 abuts against the first slider 4, and the first slider 4 can move up and down relative to the support plate 5, and also include two second sliders 6 connected to the support plate 5 that can move forward and backward. When the first slider 4 moves downward, the two second sliders 6 move in directions away from each other, and when the first slider 4 moves upward, the two second sliders 6 move in directions close to each other. The outer sides of the two second sliders 6 are both fixedly connected to horizontally arranged limit columns 7. The positioning frame 3 and the two building walls 1 are respectively provided with through holes 8 and limit holes 9 adapted to the limit columns 7, and the through holes 8 correspond to the limit holes 9 one by one. The outer sides of the two second sliders 6 refer to the two sides of the two second sliders 6 that are away from each other.

[0029] As a further explanation of this embodiment, refer to the attached Figure 5 The two second sliding blocks 6 have mutually adjacent sides which are inclined surfaces arranged opposite to each other, and the two inclined surfaces are arranged to be inclined outward from bottom to top.

[0030] As a further explanation of this embodiment, refer to the attached Figure 5The bottom surfaces of the two second sliders 6 are fixedly connected with a rectangular plate 13, and the two rectangular plates 13 are connected by a return spring 14. There are three return springs 14, and the three return springs 14 are equidistantly distributed between the two rectangular plates 13. The horizontal movement of the two second sliders 6 in the direction away from each other will stretch the return springs 14, so that when the first slider 4 moves upward, the return springs 14 will pull the two second sliders 6 to move horizontally in the direction close to each other.

[0031] As a further explanation of this embodiment, refer to the attached Figure 3-4 , a plurality of first sliders 4 are arranged in intervals from top to bottom in the positioning frame 3, and a plurality of limit assemblies are also arranged accordingly. Specifically, the number of the first sliders 4 is six, and the six first sliders 4 are evenly distributed inside the positioning frame 3, and each first slider 4 controls two limit assemblies respectively, such as Figure 5 As shown, a protrusion 15 is installed at the bottom of the two rectangular plates 13, and a slide groove 16 matched with the protrusion 15 is opened on the upper surface of the support plate 5. The two protrusions 15 can slide back and forth in the slide groove 16. When the two building walls 1 are not assembled, the end of the limiting column 7 away from the second slider 6 is inserted into the inside of the through hole 8. After the assembly of the two building walls 1 is completed, the end of the limiting column 7 away from the second slider 6 passes through the through hole 8 and is inserted into the inside of the limiting hole 9.

[0032] As a further explanation of this embodiment, refer to the attached Figure 3 The positioning frame 3 is formed by welding two identical upper and lower first baffles and two identical left and right second baffles together; a full welding method is adopted between the first baffle and the second baffle to enhance the connection stability between the two.

[0033] As a further explanation of this embodiment, refer to the attached Figure 3 and attached Figure 4 A vertically arranged screw rod 10 is rotatably installed inside the positioning frame 3, a vertically arranged threaded hole is opened on the first slider 4, the first slider 4 is threadedly connected to the screw rod 10 through the threaded hole, and a nut 11 is fixedly connected to the top of the screw rod 10. When the nut 11 is screwed in the forward direction, the first slider 4 can be driven to move vertically downward along the nut 11, and when the nut 11 is screwed in the reverse direction, the first slider 4 can be driven to move vertically upward along the nut 11.

[0034] As a further explanation of this embodiment, refer to the attached Figure 1 A first receiving groove adapted to the nut 11 is provided on the top of the positioning frame 3, and a first plug is inserted into the interior of the first receiving groove; by providing the first plug, the nut 11 can be hidden, thereby improving the overall aesthetics of the device.

[0035] As a further explanation of this embodiment, refer to the attached Figure 5The first slider 4 is also fixedly connected to a pressure plate 12, which abuts the inner sides of the two second sliders 6. The inner sides of the two second sliders 6 refer to the sides that are close to each other. Specifically, the pressure plate 12 is set in an inverted trapezoidal shape, and the front and rear side surfaces of the pressure plate 12 are respectively provided with two side surfaces that are adapted to the two inclined surfaces on the two second sliders 6. The front and rear side surfaces of the pressure plate 12 abut the two inclined surfaces on the two second sliders 6 respectively. The movement of the first slider 4 can drive the pressure plate 12 to move accordingly. Since the two side surfaces of the pressure plate abut the two inclined surfaces on the two second sliders, when the pressure plate 12 moves downward, it can drive the two second sliders 6 to move horizontally in a direction away from each other.

[0036] As a further explanation of this embodiment, refer to the attached Figure 1 A second receiving groove matched with the limiting hole 9 is provided on the building wall 1, and a second plug is inserted into the interior of the second receiving groove. By setting the second plug, the limiting column 7 can be hidden, thereby improving the overall aesthetics of the device.

[0037] The working principle of the utility model is as follows: when assembling two building walls 1, firstly, the two building walls 1 are spliced ​​together and the positioning frame 3 is clamped in the cavity formed by the two building walls 1, and then the nut 11 is screwed forwardly using an external tool, the nut 11 can drive the screw rod 10 to rotate forwardly, and the forward rotation of the screw rod 10 can drive the first slider 4 and the pressing plate 12 to move downwardly, and when the pressing plate 12 moves downwardly, it can drive the two second sliders 6 to move horizontally in the direction away from each other, and the movement of the two second sliders 6 can respectively drive the two limit columns 7 to move accordingly, so that the limit columns 7 will pass through the through holes 8 and be inserted in the inside of the limit holes 9, and the two building walls 1 can be assembled together at this time, and when the two building walls 1 need to be disassembled, only the nut 11 needs to be rotated counterclockwise to move the pressing plate 12 upward, and at this time the reset spring 14 will pull the two second sliders 6 to move horizontally in the direction close to each other, thereby releasing the connection between the two building walls 1, and the entire disassembly and assembly process can greatly improve the work efficiency of the staff.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, many improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
