Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and in particular relates to a block-assembly type shear wall structure. Background Art

[0002] Prefabricated components for assembled buildings are produced in factories and transported to the site for installation. The connection between prefabricated components has become an indispensable link. Rebar sleeve grouting connection is a common prefabricated component connection method used in engineering. Its main principle is that the embedded steel bars at one end of the lower prefabricated component are inserted into the embedded sleeve at one end of the lower prefabricated component, and a high-strength, low-expansion special grouting material is poured between the steel bars and the sleeve through the grouting hole to complete the connection of the steel bars. Its force mechanism is that under the confinement of the sleeve, the grouting material hardens, which generates friction and bite force between the steel bars, mortar and sleeve, meeting the design bearing capacity requirements. The steel sleeve grouting connection joint consists of connecting steel bars, grouting sleeves and casing grouting material.

[0003] When using steel sleeve grouting construction, the more common quality problems are: leakage, no grouting, loose grouting material, insufficient steel bar anchorage length and insufficient grouting material strength. The following are specific explanations:

[0004] (1) Leakage: The cause of leakage may be loose sealing of the connection parts of the components, insufficient strength or loose rubber plugs;

[0005] (2) No grouting: When no grouting comes out from the grouting hole or the grouting outlet, the reason is that the grouting material is insufficient;

[0006] (3) The grouting material is not dense: There are many reasons for the grouting material to be not dense. The sleeve grouting connection itself is a hidden project with a complex internal connection structure and poor project quality control. Leakage caused by loose sealing and insufficient strength of local sealing materials can also cause the grouting material to be not full and dense. It is caused by improper or non-standard construction operations of grouting workers.

[0007] (4) Steel bar anchorage problems: Steel bar anchorage problems mainly include insufficient steel bar insertion length and failure to position the steel bar. According to the specification requirements, there are strict requirements for the anchorage length of the upper and lower sections of the sleeve. The length of the steel bar inserted into the sleeve on both sides of the full grouting must not be less than 8 times the diameter of the inserted steel bar. The quality of steel bar anchorage will have a serious impact on the quality of sleeve grouting;

[0008] (5) Insufficient strength of grouting material. The grouting material quality problems itself or the quality problems of grouting material caused by human factors of construction personnel, operating errors, lax construction supervision and other factors may cause insufficient strength of grouting material, thus affecting the quality of sleeve grouting connection.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figures 1 to 5 As shown, in an illustrative embodiment of the block-assembled shear wall structure of the utility model, the block-assembled shear wall structure includes an outer frame 1 integrally cast with concrete, and the outer frame 1 has two transverse beams 11 and two vertical columns 12.

[0042] The two cross beams 11 are divided into an upper cross beam 13 and a lower cross beam 14 , and the upper cross beam 13 and the lower cross beam 14 are arranged at intervals in the upper and lower directions.

[0043] The two columns 12 are divided into a left column 15 and a right column 16 , and the left column 15 and the right column 16 are arranged at intervals on the left and right.

[0044] The interior component 2 is installed in the assembly area 17 surrounded by the upper cross beam 13 , the lower cross beam 14 , the left column 15 and the right column 16 .

[0045] The interior component 2 includes a plurality of prefabricated panels 21 arranged side by side, the lower side of the upper cross beam 13 and the upper side of the lower cross beam 14 are integrally provided with a plurality of assembly teeth 18 , and the upper and lower edges of the interior component 2 are provided with a plurality of assembly grooves 22 .

[0046] The assembly teeth 18 are inserted into the corresponding assembly grooves 22 , the first metal sheets 31 are fixed on the tooth surfaces of the assembly teeth 18 , the second metal sheets 32 are fixed on the inner walls of the assembly grooves 22 , and the first metal sheets 31 are welded to the corresponding second metal sheets 32 .

[0047] The assembly area 17 matches the interior component 2 so that the inner wall of the assembly area 17 fits with the outer edge of the interior component 2. The upper, lower, left and right beams 11 and columns 12 constrain the middle interior component 2 so that the prefabricated panels 21 in the interior component 2 are tightly attached to each other.

[0048] The upper and lower cross beams 11 limit the prefabricated panels 21 in the interior assembly 2 in the left and right directions through the assembly teeth 18, further improving the stability of the interior assembly 2 in the assembly area 17. The prefabricated panels 2 and the cross beams 11 are firmly connected by welding between metal sheets, so that the interior assembly 2 is firmly connected to the inside of the outer frame 1.

[0049] In the above-mentioned schematic embodiment, the shear wall in the block-assembled shear wall structure is assembled by an integrally cast outer frame and internal components spliced ​​by prefabricated panels. The prefabricated panels and beams are assembled by teeth and grooves, and are further connected by welding of metal sheets. This ensures that the internal components can be firmly assembled and combined with the outer frame, improves the connection quality of the building components, and solves the problem of poor connection quality existing in the original connection of building components by steel sleeve grouting.

[0050] In some embodiments, both the cross beam 11 and the prefabricated panel 21 have support steel bars 4, which serve as the skeleton of the cross beam 11 and the prefabricated panel 21. The first metal sheet 31 and the second metal sheet 32 ​​are welded to the corresponding support steel bars 4, thereby improving the firmness of the metal sheets fixed in the assembly teeth 18 and the assembly grooves 22, and ensuring that the interior components 2 are firmly connected to the inside of the outer frame 1.

[0051] In some embodiments, there are multiple assembly blocks 5 between adjacent prefabricated panels 21, one side of the assembly block 5 is located in the assembly groove 23 opened at the edge of the prefabricated panel 21 on one side, and the other side of the assembly block 5 is located in the assembly groove 23 opened at the edge of the prefabricated panel 21 on the other side. The assembly block 5 is a metal part, and the inner wall of the assembly groove 23 is fixed with a third metal sheet 33, and both sides of the assembly block 5 are welded to the third metal sheet 33 on the corresponding side.

[0052] The assembly block 5 can limit the positions of two adjacent prefabricated panels 21 in the length direction, thereby improving the firmness of the interior assembly 2 formed by the prefabricated panels 21. In addition, the assembly blocks 5 are welded to the corresponding prefabricated panels 21 on one side by metal sheets, so that even if the prefabricated panels 21 in the interior assembly 2 are welded to each other by the assembly blocks 5, the stability of the interior assembly 2 is further improved, thereby ensuring that the interior assembly 2 is firmly connected to the inside of the outer frame 1.

[0053] In some embodiments, the space enclosed by two relative assembly grooves 23 matches the corresponding assembly block 5, that is, the outer contour of the assembly block 5 is the same as the contour of the area enclosed by the two adjacent assembly grooves 23, so that the side of the assembly block 5 can be completely fitted with the inner wall of the assembly groove 23, thereby improving the support and limiting effect of the assembly block 5 on the prefabricated panel 21.

[0054] In some embodiments, the assembly block 5 is a diamond-shaped block, so that the side surfaces of the assembly block 5 are inclined toward the prefabricated panel 21 on one side, so that the mutual support of the prefabricated panels 21 through the assembly block 5 can be generated in the vertical and left and right directions, thereby improving the stability of support and limitation.

[0055] In some embodiments, the third metal sheet 33 is welded to the supporting steel bars 4 provided in the prefabricated panel 21 , so as to improve the stability of fixing the third metal sheet 33 on the prefabricated panel 21 .

[0056] In some embodiments, two adjacent rows of assembly blocks 5 are staggered so that the supporting effect of the assembly blocks 5 can be more fully exerted on various positions of the internal components.

[0057] In some embodiments, the prefabricated panels 21 in the interior assembly 2 are arranged in sequence along the up-down direction or along the left-right direction.

[0058] When the prefabricated panels 21 are arranged in the up-down direction, as shown in FIG. Figure 2 and Figure 4 As shown, only the top and bottom prefabricated panels 21 are provided with assembly grooves 22. When the prefabricated panels 21 are arranged in the left and right directions, as shown in FIG. Figure 1 and Figure 3 As shown, each prefabricated panel 21 is provided with a mounting groove 22 at the top and the bottom.

[0059] The prefabricated panels 21 can be arranged in two directions, thereby increasing the flexibility of assembling the prefabricated components.

[0060] In some embodiments, the front side and the rear side of the outer frame 1 protrude forward or backward relative to the interior component 2, so that the interior component 2 cannot completely fill the assembly area 17. Concrete can be poured in the assembly area 17 and cover the front side and the rear side of the interior component 2, completely hiding the interior component 2, and the poured concrete can be flush with the outer frame 1, making the shear wall smoother and more beautiful.

[0061] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0062] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
