Description

TECHNICAL FIELD

[0001] The present application belongs to the field of prefabricated building technology, and particularly relates to a pre-buried nut assembly type shear wall and a production method thereof. BACKGROUND

[0002] At present, domestic building shear walls are widely used, but the traditional shear walls have problems of low production efficiency, serious environmental pollution, difficult engineering quality guarantee, and large resource consumption. The production process of the traditional double-sided composite shear wall is to pour one wall panel and then pour the other wall panel after turning over, which is relatively complex. At present, there is a passive low-energy prefabricated wall and a building comprising the wall (publication number CN218405900U), which comprises two inner and outer wall panels, a steel mesh and a nut are arranged in the two wall panels, and the nuts of the two wall panels are connected through fiber thread reinforced bars (i.e. tension rods). The two wall panels can be produced separately and assembled on site, meeting the requirements of prefabricated buildings. However, the following deficiencies exist in the production and assembly process of the existing two wall panels and are analyzed as follows:

[0003] Firstly, since the two wall panels are separately molded, there are errors in the hole position, hole distance and hole direction of each nut of the two wall panels when they are formed in the mold. When the two wall panels are assembled, it is required to keep them parallel and at the same time, each nut on the two wall panels is connected through a plurality of tension rods, and each group of nuts is required to be one-to-one corresponding and concentric. However, the existing technology is difficult to meet the above assembly requirements (when there is at least one group of nuts (i.e. the first nut and the second nut in the publication number CN218405900U) between the two wall panels, the hole positions do not correspond or are not concentric, or the hole distances between any two groups of nuts are not corresponding or are not parallel, which cannot be matched and assembled).

[0004] Secondly, the existing wall panels are produced in a single mold and single piece in the factory, which is still low in efficiency and high in cost, and needs to be further improved.

[0005] Thirdly, each nut on the existing wall panel is welded to the steel mesh as a whole, and it is required that each nut on the two wall panels to be matched keeps parallel, concentric, hole position, hole distance and hole direction without difference after welding. Therefore, the welding process is extremely difficult. In the conventional mold, the steel mesh is positioned and fixed before pouring concrete, and the steel mesh is easily extruded, skewed or deformed during pouring. Therefore, the positions and directions of each nut on the wall panel after molding will change (i.e. the hole position, hole distance and direction will shift or move), which will affect the later alignment and parallel tension assembly. SUMMARY

[0006] The application provides a production method of a pre-buried nut assembly type shear wall, which simultaneously solves the problems of the current production process, such as unbatch production, low efficiency, high cost, and the combination problem of the hole position, hole distance, and concentricity of each group of nuts, which cannot be matched and assembled when two wall plates (inner and outer) are assembled.

[0044] The present application will be further described below in combination with the drawings and embodiments:

[0045] Embodiment one: can be seen from Figs. 1-13 , a production method of a pre-embedded nut assembly type shear wall, characterized in that it comprises the following steps:

[0046] S10, a plurality of pre-embedded nuts 1-1 (6 in the figure) are connected in series through temporary screw rods 1-2, and any two adjacent pre-embedded nuts 1-1 are separated by foam pipes 1-3 to make a set assembly 1 (see Fig. 1 ); Fig. 1

[0047] S20, steel mesh 2 is made (see Figs. 2-3 );

[0048] S30, a plurality of steel mesh 2 (6 in the figure) and a plurality of set assemblies 1 are assembled into a mold and fixed to each other; each steel mesh 2 is vertically arranged and distributed in parallel at equal intervals; each set assembly 1 is horizontally arranged and distributed in parallel (13 in the figure), and each temporary screw rod 1-2 is inserted into the positioning hole 3-11 on the two side molds 3-1 at both ends, and each foam pipe 1-3 is located at the middle position between the adjacent two steel mesh 2 (see Figs. 4-6 ); Fig. 8 Fig. 4

[0049] S40, the mold 3 is poured with concrete and vibrated to be compacted (see Fig. 5 );

[0050] S50, when the concrete is initially cured, all the set assemblies 1 are taken out (see Fig. 8 ​​​The temporary screw rod 1-2 can be seen in 13 places Fig. 6

[0051] S60, cutting the concrete into several pieces of wallboard 4 (see Figs. 6-7 , a total of 5 places can be seen) as the cutting position in the middle of each foam tube 1-3 (see Fig. 7 , a total of 6 can be seen);

[0052] S70, the inner surface of the wallboard 4 is chiseled and cleaned (see Fig. 8 , in addition, it should be noted that the opposite surface of the two wallboards 4 during the assembly of the tension screw rod 5 in step S80 is the inner surface of the wallboard 4);

[0053] S80, the tension screw rod 5 is screwed into the embedded nut 1-1 of the two adjacent wallboards 4 after cutting (see Fig. 9 ).

[0054] The above steps are to produce prefabricated embedded nut assembly shear walls in the factory. The prefabricated embedded nut assembly shear wall is transported to the construction site, hoisted into place, and the hollow part of the shear wall is poured with commercial concrete. After pouring and forming, a complete shear wall is formed after curing. The chiseling treatment of the inner surface of the wallboard 4 in step S70 is mainly to make the new and old concrete adhere better.

[0055] When pouring concrete in the mold, the embedded nuts 1-1 of each set of components 1 are coaxially connected by the temporary screw rod 1-2, which ensures that each embedded nut 1-1 of each set of components 1 remains concentric after solidification. Since each set of components 1 is positioned by inserting the temporary screw rod 1-2 into the positioning hole 3-11 of the two side molds 3-1, it can ensure that each set of components 1 remains parallel, concentric, and has the same hole position and spacing after the mixed soil solidifies. It can ensure that the cut wallboards 4 formed in the same mold can be paired and assembled.

[0056] The present application can complete batch production quickly, has high production efficiency, low cost, and can ensure the hole position, hole spacing and parallelism precision of each nut on the single wallboard after forming. At the same time, the hole positions of the nuts of the two inner and outer wallboards are one-to-one corresponding, concentric, have the same hole spacing and are parallel to each other during the assembly of the tension screw rod, which can meet the requirements of normal assembly of all tension screw rods.

[0057] ​The present application can avoid the cutting tool from being damaged by the steel mesh and the embedded nut 1-1 during cutting, ensure normal cutting processing, and ensure the stability of the steel mesh and the embedded nut 1-1 of the wallboard, and protect the overall strength of the wallboard.

[0058] In addition, the tension screw 5 is screwed into the embedded nut 1-1 of the adjacent two wallboards 4 after cutting, and the positions of the embedded nuts 1-1 on the two wallboards 4 correspond to each other, which is more consistent and can further increase the assembly ability and overcome the influence of the straightness tolerance of the tension screw 5 itself on the assembly ability.

[0059] Specifically, the length of the foam pipe is greater than the thickness of the cutting saw piece in step S60 to prevent the embedded nut from being cut by mistake during cutting.

[0060] Preferably, in step S10, the embedded nut 1-1 is circular, and the foam pipe 1-3 is sealed at both ends by sleeving with the end portions of the adjacent two embedded nuts 1-1 (see Fig. 1 Compared with other embodiments such as being connected together in a head-to-tail manner, this structure has better sealing effect.

[0061] The mold includes a bottom plate and four side molds (distributed in a rectangular shape) which are detachably assembled and fixed. The left and right two side molds 3-1 are provided with positioning holes 3-11 for inserting and positioning the end portions of the temporary screw 1-2. The difference between the mold of the present application and the existing mold is that a plurality of pairs of positioning holes 3-11 are arranged on the left and right opposite two side molds 3-1 of the existing mold 3. In this embodiment, there are 13 sets of components 1 (i.e. 13 temporary screws 1-2), and correspondingly, 13 pairs of positioning holes 3-11 are arranged on the mold 3.

[0062] Preferably, the foam pipe 1-3 is sleeved with the adjacent two embedded nuts 1-1 at both ends to form a stepped seal, which can improve the sealing effect and completely prevent the concrete from entering the inside of the embedded nut 1-1 during pouring, and the assembly is simple.

[0063] Wherein, in the S30 step, the embedded nut 1-1 on the assembled component 1 is fixed with the steel mesh 2 through binding, clamping or buckling or other ways. It can make the steel mesh 2 and the embedded nut 1-1 fixed and stable in position, and can ensure that the steel mesh 2 is in the middle position of the embedded nut 1-1 during pouring, avoiding the steel mesh being inclined too much to affect normal cutting processing.

[0064] Wherein, in the S30 step, the embedded nut 1-1 on the assembled component 1 is fixed with the steel mesh 2 through binding, clamping or buckling or other ways. It can make the steel mesh 2 and the embedded nut 1-1 fixed and stable in position, and can ensure that the steel mesh 2 is in the middle position of the embedded nut 1-1 during pouring, avoiding the steel mesh being inclined too much to affect normal cutting processing. Fig. 4 The two embedded nuts 1-1 on the two ends of the assembled component 1 are respectively in contact with the inner wall of the two side molds 3-1 to seal, which can avoid the concrete entering the embedded nut 1-1 from the inner wall of the side mold 3-1 and the embedded nut 1-1 on the end side during pouring, or falling on the temporary screw rod 1-2 and cannot be taken out normally.

[0065] In other embodiments, in the S30 step, a sealing sleeve can be arranged between the embedded nut 1-1 on the end side of the assembled component 1 and the inner wall of the side mold 3-1 to achieve sealing, so that the concrete cannot enter the embedded nut 1-1 during pouring. Specifically, the sealing sleeve can be made of foam material or rubber material.

[0066] Wherein, in the S20 step, the steel mesh 2 is made by binding or welding at the cross intersection of the several spaced and parallel distributed longitudinal steel bars 2-1 and the several spaced and parallel distributed transverse steel bars 2-2 (see Figs. 2-3 The structure and manufacturing of the steel mesh 2 can adopt the existing technology, so it is not described in detail.

[0067] Wherein, in the S80 step, the two wallboards 4 are first hoisted to the positioning frame 6 for accurate positioning, and then the tensioning screw rod 5 is screwed into the embedded nut 1-1 of the two wallboards 4 (see Figs. 10-11 After the two wallboards 4 are hoisted to the positioning frame 6 and accurately positioned left and right, front and back, up and down, it can ensure that each tensioning screw rod 5 can be screwed into the embedded nut 1-1 of the two wallboards 4 more quickly and accurately.

[0068] Each embedded nut 1-1 on the wallboard 4 can be used as a hoisting hole, and there are enough hoisting hole positions, so that the hoisting method is flexible during the assembly in step S80, and the hoisting embedded part is avoided to be arranged on the wallboard 4.

[0069] See Figs. 10-13In the embodiment, the positioning frame 6 comprises a placing platform 6-1, a sliding frame 6-2, a first limiting block 6-3 and a positioning block 6-4. The first limiting block 6-3 and the positioning block 6-4 are fixed on the placing platform 6-1 and oppositely arranged. The sliding frame 6-2 has a flat plate 6-21 and a vertical plate 6-22. The flat plate 6-21 is provided with a strip-shaped groove 6-23. The placing platform 6-1 is fixed with a threaded column 6-5. The threaded column 6-5 penetrates through the strip-shaped groove 6-23 upwardly and cooperates with a locking nut 6-6. The vertical plate 6-22 is provided with a positioning pin 6-7 on a side surface facing the first limiting block 6-3, which is used for cooperating with the pre-buried nut 1-1 of the wallboard 4 (in the embodiment, the positioning pin 6-7 has four, which can be cooperated with four pre-buried nuts 1-1 for positioning respectively). Specifically, the first limiting block 6-3 is T-shaped, and has two positioning steps 6-31 for spacing positioning and alignment positioning of the two wallboards 4.

[0070] Therefore, in the step S80, the two wallboards 4 are first hung vertically on the placing platform 6-1 and are horizontally supported and have the same height, and then the two wallboards 4 are respectively attached to the first limiting block 6-3 and the positioning block 6-4 and the front edges of the two wallboards 4 are simultaneously aligned and contacted with the two positioning steps of the first limiting block 6-3, so that the two wallboards 4 are kept parallel and have a constant spacing, and the two wallboards 4 are accurately positioned in the left-right, front-back and up-down directions. Figs. 10-13 Then, the locking nut 6-6 on the threaded column 6-5 is loosened upwardly, the sliding frame 6-2 is slid to the left and the wallboard 4 on the right side is pressed, the positioning pins 6-7 on the vertical plate 6-22 of the sliding frame 6-2 are cooperated with the pre-buried nuts 1-1 on the wallboard 4 one by one, and the cooperation length of the positioning pin 6-7 and the pre-buried nut 1-1 is only 1 / 5 of the total length of the inner hole of the pre-buried nut 1-1, that is, a small section is reserved for cooperation and positioning, so that the normal assembly of the tension screw rod 5 is not affected. Then, the locking nut 6-6 on the threaded column 6-5 is tightened downwardly and locked in place, and the sliding frame 6-2 cannot be displaced and is kept in the state of positioning and pressing. Then, the tension screw rod 5 is screwed into each group of pre-buried nuts 1-1 of the two wallboards 4 respectively. Then, the locking nut 6-6 on the threaded column 6-5 is loosened upwardly, the sliding frame 6-2 is slid to the right and is withdrawn and away, and then the tension screw rod 5 in the locking nut 6-6 reserved by the positioning pin is further screwed in place to be assembled into the pre-buried nut assembly type shear wall.

[0071] The positioning frame 6 of the present application can be used for the rapid assembly of the pre-buried nut assembly type shear wall, has the advantages of accurate positioning, simple operation, fast assembly efficiency and the like.

[0072] Embodiment two can be seen from Figs. 15-18The utility model provides a kind of embedded nut assembly type shear wall, including two pieces of the wallboard 4, the wallboard 4 is provided with embedded nut 4-1 and steel mesh 2, and the embedded nut 4-1 of the two pieces of the wallboard 4 is connected by tensioning screw 5.

[0073] And the key is that the embedded nut 1-1 has connecting part 1-11 for being connected with the steel mesh 2 and being simultaneously limited to rotate and axial displacement. Figs. 15-18 Since the embedded nut 1-1 has connecting part 1-11 for being connected with the steel mesh 2 and being simultaneously limited to rotate and axial displacement, the connection strength between the embedded nut 1-1 and the concrete and the steel mesh 2 can be enhanced, the problem that the embedded nut 1-1 rotates and axially loosens in the concrete when the embedded nut 1-1 is subjected to axial tension and compression force and torsion of the tensioning screw can be avoided, and the overall strength of the assembled shear wall is improved, while the long-term reliability and stability of the strength are maintained.

[0074] As shown in Figs. 17-18 The embedded nut 1-1 has two connecting parts 1-11, and the two connecting parts 1-11 are provided with two clamping grooves 1-111 respectively for clamping cooperation with the longitudinal reinforcement 2-1 and the transverse reinforcement 2-2, and the two clamping grooves 1-111 are perpendicular to each other.

[0075] As shown in Figs. 17-18 The clamping groove 1-111 is U-shaped, the bottom end 1-112 of the U-shaped is circular with an enlarged outer shape, and the inner diameter of the U-shaped is preferably about 2-3 mm larger than the gap tolerance between the longitudinal reinforcement 2-1 (or the transverse reinforcement 2-2). Since a certain movement allowance needs to be left when the embedded nut 1-1 of the assembly 1 is connected with the steel mesh 2 and then bundled in step S30, the steel mesh 2 cannot be completely consistent and absolutely parallel, and there is a deviation, and the problem that all the embedded nuts 1-1 of the assembly 1 cannot be simultaneously assembled by reserving the matching allowance can be avoided.

[0076] As shown in Figs. 17-18 Preferably, the connecting part 1-11 is buckled with the longitudinal reinforcement 2-1 or / and the transverse reinforcement 2-2 of the steel mesh 2.

[0077] As shown in Figs. 17-18 Further, the embedded nut 1-1 is provided with a protruding rod part 1-12 extending outward on the outer wall. The protruding rod part 1-12 can increase the matching length with the concrete and improve the loosening resistance.

[0078] As shown in Figs. 17-18Further, the convex rod part 1-12 is provided with a head 1-13 with increased outer shape at the outer end. The head 1-13 with increased outer shape has a function of preventing falling off (hooking the concrete to generate great resistance, preventing falling off), further improving the loosening resistance.

[0079] Please refer to ​ In addition, the pre-embedded nut 1-1 is provided with a positioning ring table 1-14 at both ends for sleeving and cooperating with the end of the foam pipe.

[0080] The above describes the preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment based on the prior art according to the concept of the present application should be within the protection scope determined by the claims.
