Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and in particular to a connection node between assembled load-bearing walls. Background Art

[0002] At present, in order to meet the needs of production and manufacturing, there are a large number of temporary buildings. Temporary building structures are usually assembled from container structures or overlapped with color steel plates. They have poor sound insulation, weak structural bearing capacity and are prone to rust. Compared with concrete buildings, the living experience is poor.

[0003] Conventional concrete buildings include shear walls and masonry walls. Shear walls are formed by directly pouring concrete, while masonry walls are built using blocks after the main structure is completed. Both of the above-mentioned walls are constructed on-site, with a long construction period, and after construction is completed, they form permanent building structures that cannot be demolished.

[0004] The wall construction of conventional prefabricated buildings usually involves hoisting the prefabricated wall to the construction site, and then injecting grouting liquid between the wall and the wall panels to form a stable installation of the prefabricated wall. The connection nodes formed by this construction method make it impossible to disassemble and reuse the prefabricated wall at a later time. Utility Model Content

[0005] Based on the above description, the utility model provides a connection node between prefabricated load-bearing walls to solve the problem that the prefabricated walls are difficult to disassemble and reuse after construction is completed.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a connection node between assembled load-bearing walls, characterized in that it includes a first wall and a second wall, wherein the first wall and the second wall are spliced;

[0007] A first mortise and tenon groove is formed on the end surface of the first wall, a second mortise and tenon groove is formed on the end surface of the second wall, and a plurality of vertically stacked mortise blocks are arranged between the first wall and the second wall;

[0008] When the first wall and the second wall are spliced, any one of the mortise blocks is inserted into the first mortise groove and the second mortise groove at the same time, and the shape of the mortise block matches the shape of the first mortise groove and the second mortise groove after being connected.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the first wall body and the second wall body both include a main wall section and a connecting section arranged on one side of the main wall section, and the first mortise and tenon groove and the second mortise and tenon groove are both opened in the connecting section.

[0011] Furthermore, the first mortise and tenon grooves and the second mortise and tenon grooves are both opened throughout the height of the first wall and the second wall.

[0012] Furthermore, the cross-sectional width of the first mortise and tenon groove near the middle area of ​​the first wall is greater than the cross-sectional width of the first mortise and tenon groove near the end surface of the first wall;

[0013] The cross-sectional width of the second tongue and groove near the middle area of ​​the second wall is greater than the cross-sectional width of the second tongue and groove near the end surface of the second wall.

[0014] Furthermore, after the plurality of mortise blocks are inserted into the first mortise groove and the second mortise groove, the top surfaces of the mortise blocks are coplanar with the top surfaces of the first wall and the second wall.

[0015] Furthermore, hidden beams are provided on the tops of the first wall and the second wall, and the structural strength of the hidden beams is greater than the structural strength of other parts of the first wall and the second wall.

[0016] Furthermore, a hidden column is vertically arranged in the first wall or the second wall, and the structural strength of the hidden column is greater than the structural strength of other parts of the first wall and the second wall.

[0017] Furthermore, a clamping groove is provided on the top surface of any one of the mortise blocks.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] 1. The present application realizes the connection of two adjacent assembled load-bearing walls by inserting the mortise blocks into the first mortise groove and the second mortise groove, which is quick and convenient; in addition, vertically stacking a plurality of mortise blocks facilitates construction on the one hand, and on the other hand, due to slight errors in the production process, different mortise blocks are pressed against the wall at different points, and a plurality of mortise blocks are provided to realize stable connection with the assembled load-bearing wall from all directions, so that the connection strength of the two adjacent assembled load-bearing walls is stronger;

[0020] 2. The first mortise and tenon grooves and the second mortise and tenon grooves are configured as structures with variable cross-sections, so that a mortise and tenon connection is formed between the mortise block and the assembled load-bearing wall, thereby limiting the positions of the first wall and the second wall in the horizontal direction;

[0021] 3. The prefabricated load-bearing walls of this application are provided with concealed beams and concealed columns, which can serve as the main load-bearing components of the building to transmit force, which is different from the design concept that the walls in conventional prefabricated buildings do not participate in the main force transmission.

[0026] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] Example 1

[0029] A connection node between assembled load-bearing walls, referring to Figure 1 and Figure 2 , including adjacent first wall 1 and second wall 2, which are connected after being spliced. It should be noted that the first wall 1 and the second wall 2 of the present application are load-bearing walls, similar to the shear wall structure in the cast-in-place concrete structure, and are essentially different from masonry partition walls that only serve to separate spaces.

[0030] Specifically, a hidden beam 4 is provided at the top of the first wall 1 and the second wall 2. The thickness of the hidden beam 4 is the same as the thickness of the first wall 1 or the second wall 2, but the structural strength of the hidden beam 4 is greater than the structural strength of other areas of the wall. The structural strength can be enhanced by increasing the density of steel bars in the hidden beam 4 or increasing the concrete strength of the hidden beam 4.

[0031] Hidden columns 5 can also be set in the wall of the prefabricated load-bearing wall of the present application. Hidden columns 5 are not required to be set in every wall, and the positions of the hidden columns 5 in each wall are not the same. A hidden column 5 can be set at a certain distance according to the bearing capacity requirements. The embodiment of the present application takes the hidden column 5 set in the first wall 1 as an example for explanation and illustration.

[0032] The hidden column 5 is arranged along the height direction of the first wall 1, and the structural strength of the hidden column 5 is greater than the structural strength of other parts of the first wall 1, and the other parts do not include the area of ​​the hidden beam 4. The thickness of the hidden column 5 is consistent with the thickness of the first wall 1, and the structural strength of the hidden column 5 can be increased by increasing the steel bar binding density in the hidden column 5 and changing the concrete strength in the hidden column 5.

[0033] In the present application, a first mortise and tenon groove 11 is provided on the end surface of the first wall 1 , and the first mortise and tenon groove 11 is provided throughout the height of the first wall 1 ; a second mortise and tenon groove 21 is provided on the end surface of the second wall 2 , and the second mortise and tenon groove 21 is also provided throughout the height of the second wall 2 .

[0034] In addition, the cross-sectional width of the first tenon groove 11 near the middle area of ​​the first wall 1 is greater than the cross-sectional width of the first tenon groove 11 near the end surface of the first wall 1, and the cross-sectional width of the second tenon groove 21 near the middle area of ​​the second wall 2 is greater than the cross-sectional width of the second tenon groove 21 near the end surface of the second wall 2. For example, the first tenon groove 11 and the second tenon groove 21 can be trapezoidal or T-shaped.

[0035] A plurality of vertically stacked mortise blocks 3 are arranged between the first wall 1 and the second wall 2. When the first wall 1 and the second wall 2 are spliced, any mortise block 3 is simultaneously inserted into the first mortise groove 11 and the second mortise groove 21, and the horizontal cross-sectional shape of the mortise block 3 matches the shape of the first mortise groove 11 and the second mortise groove 21 after being connected.

[0036] A plurality of vertically stacked mortise blocks 3 are provided. On the one hand, the height of a single mortise block 3 is relatively low, so that construction workers can place the mortise blocks 3 in the first mortise groove 11 and the second mortise groove 21 conveniently. On the other hand, although the shape of the mortise blocks 3 matches the shape of the first mortise groove 11 and the second mortise groove 21 after being connected, there are production errors in the manufacturing process, so that after the mortise blocks 3 are inserted into the first mortise groove 11 and the second mortise groove 21, the degree of tightness between various areas of the side walls of the mortise blocks 3 and different areas of the side walls of the first mortise groove 11 and the second mortise groove 21 is different. Therefore, through multiple mortise blocks 3, tightness with the first wall 1 and the second wall 2 in various directions can be achieved, and the connection strength of the first wall 1 and the second wall 2 can be enhanced, so that the connection nodes of the present application have strong capabilities to resist torque, shear force and bending moment.

[0037] Furthermore, after the plurality of mortise blocks 3 are inserted into the first mortise groove 11 and the second mortise groove 21, the top surface of the uppermost mortise block 3 is coplanar with the top surfaces of the first wall 1 and the second wall 2, so that after the first wall 1 and the second wall 2 are spliced, there is no groove on the top, which is more beautiful on the one hand, and facilitates the transmission of force from the upper structure to the load-bearing wall on the other hand.

[0038] Preferably, a clamping groove is provided on the top of each mortise block 3, so that when the first wall 1 and the second wall 2 need to be disassembled, the mortise block 3 can be conveniently clamped by a tool and taken out from the first mortise groove 11 and the second mortise groove 21.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is that, referring to Figure 1 and Figure 2 The first wall 1 and the second wall 2 both include a main wall section 12 and a connecting section 13 disposed on one side of the main wall section 12, and the first mortise and tenon groove 11 and the second mortise and tenon groove 21 are both provided in the connecting section 13. By providing the connecting section 13, the influence of the first mortise and tenon groove 11 and the second mortise and tenon groove 21 on the structural strength and structural integrity of the first wall 1 and the second wall 2 is reduced; in addition, the structural form of the connecting section 13 is not limited, and can be a steel structure or other high-strength materials, so that the first mortise and tenon groove 11 and the second mortise and tenon groove 21 are easier to manufacture and form; by reasonably providing the material of the connecting section 13, the structural strength of the connection can be enhanced, thereby achieving a more stable connection between the first wall 1 and the second wall 2.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
