Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a shear wall frame and a shear wall. Background Art

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls or structural walls, are a common structural system in construction projects. They are widely used in my country's building structure design and can effectively reduce the probability of lateral displacement of building structures. Shear walls are walls in houses or structures that mainly bear vertical and horizontal loads caused by wind loads or earthquakes, preventing the structure from being damaged by shear and improving the stability of the entire building. Shear walls are usually located in the core area of ​​the building and are distributed along the length and width of the building. Generally, the shear wall structure in a house is in the form of a concrete wall, which can effectively resist lateral thrust or tension.

[0003] On-site construction of shear walls is a key part of construction projects, which usually includes steps such as steel bar installation, formwork construction, concrete pouring, and maintenance. During the construction process, it is necessary to strictly follow the design requirements and engineering standards to ensure the accuracy, stability, and durability of the shear walls to meet the earthquake and wind resistance requirements of the building. At the same time, attention should be paid to quality management and safety control to ensure a safe and orderly construction process. With the unprecedented development of the construction industry, the precision requirements for each link of shear wall construction are getting higher and higher. Strict control of various parameters and quality indicators during the construction process is a key factor in ensuring the safety and reliability of shear wall structures.

[0004] At present, the construction of shear wall frames usually relies on a large amount of manual operation. The vertical and transverse steel bars that constitute the shear wall frames are tied manually, but manual operation is difficult to fully guarantee the accuracy of construction, and it is easy to cause problems such as steel bar dislocation. When the shear wall is poured, it is difficult to ensure that the spacing between the vertical and transverse steel bars remains fixed. The vertical and transverse steel bars are prone to offset and the thickness of the steel bar protective layer is inconsistent. These problems can easily lead to quality problems such as cracking, exposed steel bars, and leakage during the use of the shear wall, thereby affecting the overall quality of the shear wall. Utility Model Content

[0005] The utility model aims to provide a shear wall with a skeleton structure, which can ensure that the spacing between vertical and horizontal steel bars remains unchanged when the shear wall is cast, avoid the deviation and misalignment of the steel bars, further ensure the consistency of the thickness of the steel bar protection layer, and ensure the overall quality of the shear wall.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] The shear wall skeleton includes a plurality of vertical steel bars and a plurality of transverse steel bars, wherein the plurality of vertical steel bars and the plurality of transverse steel bars are vertically staggered to form a rectangular frame. The shear wall skeleton also includes:

[0009] A plurality of draw hooks are provided, and two ends of the draw hooks are pressed against the intersection points of the vertical steel bars and the horizontal steel bars relative to the rectangular frame, so that the rectangular frame is pressed against the fixing piece.

[0010] Preferably, the plurality of fixing members are arranged in a rectangular shape or a plum blossom shape.

[0012] Preferably, the fixing member is a columnar structure.

[0013] Preferably, the fixing member is made of concrete casting.

[0014] Preferably, the vertical groove and the transverse groove are arc-shaped grooves or rectangular grooves.

[0015] Preferably, the fixing device includes a column body and a protrusion, and a plurality of protrusions are protruding from both ends of the column body. The gaps between the protrusions on the same side form vertical grooves or transverse grooves, and the length of the protrusion protruding from the column body is greater than the sum of the outer diameters of the vertical and transverse steel bars.

[0016] Preferably, the gap distance between adjacent protrusions is equal to the outer diameter of the vertical steel bars or the outer diameter of the transverse steel bars.

[0017] Preferably, a plurality of reinforcing ribs extending along the length direction of the column body are arranged inside the column body.

[0031] See also Figures 1 to 4As shown, the present application provides a shear wall skeleton, including multiple vertical steel bars 1, multiple transverse steel bars 2, multiple fixing members 3 and multiple hooks 4; multiple vertical steel bars 1 and multiple transverse steel bars 2 are vertically staggered to form a rectangular frame, the vertical steel bars 1 can increase the shear resistance of the shear wall in the vertical direction, and the transverse steel bars 2 can increase the bending stiffness of the shear wall, and the two are staggered to form a rectangular frame structure, so that the shear wall can effectively bear the shear force under the action of horizontal loads, play a role in supporting and resisting horizontal loads such as earthquakes, thereby improving the bearing capacity and overall stability of the wall; multiple fixing members 3 are arranged in the rectangular frame, and their two ends correspond to the intersection points of the vertical steel bars 1 and the transverse steel bars 2 relative to the rectangular frame, and each fixing member 3 is provided with intersecting vertical grooves 5 and transverse grooves 6 at both ends, so that the vertical steel bars 1 are embedded in the vertical grooves 5, and the transverse steel bars 2 are embedded in the transverse grooves 6, thereby fixing the vertical steel bars 1 and the transverse steel bars 2, and when the shear wall is poured, the vertical steel bars are ensured The positions and spacings of the vertical reinforcements 1 and the horizontal reinforcements 2 are fixed, thereby ensuring that the vertical reinforcements 1 and the horizontal reinforcements 2 do not deviate, further improving the stability and seismic performance of the shear wall structure; the two ends of the hook 4 are pressed against the intersection of the vertical reinforcements 1 and the horizontal reinforcements 2 relative to the rectangular frame, so that the rectangular frame is pressed against the fixing member 3. The hook 4 is a prior art and will not be described in detail; the connection strength between the fixing member 3 and the rectangular frame is further improved by the hook 4, and the stability of the rectangular frame is further increased by pressing the two ends of the fixing member 3 against the rectangular frame; at the same time, the fixing member 3 and the hook 4 are used in combination to ensure that the reinforcement does not deviate while reducing manual operations during the construction process, and can effectively solve the problems of large manual operation errors, easy to cause wall size deviations, reinforcement dislocation and inconsistent reinforcement protective layer thickness, simplify the construction process, improve construction efficiency and reduce project costs; reduce quality defects that occur during the use of the shear wall, reduce potential safety hazards, extend its service life and reduce maintenance costs.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, a plurality of fixing members 3 are arranged in a rectangular or plum blossom shape. The fixing members 3 arranged in a rectangular or plum blossom shape can withstand greater tensile, shear and torsional forces, thereby increasing the bending and shearing resistance of the wall, making the shear wall more able to withstand horizontal loads such as earthquakes, effectively improving its seismic performance and overall stiffness, and reducing the risk of collapse of the shear wall when it is affected by external forces such as earthquakes. Preferably, the fixing members 3 and the hooks 4 are staggered. This distribution method makes the structural connection of the rectangular frame, the fixing members 3 and the hooks 4 more stable, thereby effectively transmitting and dispersing the load, reducing the risk of structural fatigue and damage, and by ensuring the firmness and reliability of the connection, the shear wall can be effectively protected from damage, and its service life can be extended, thereby improving the safety and reliability of the structure.

[0033] like Figure 3 As shown, in some embodiments, the fixing member 3 is a columnar structure, which has good compressive and bending bearing capacity, can effectively bear vertical and horizontal loads, thereby enhancing the stability of the fixing member 3 structure, helping to reduce the deformation and deflection of the structure, and improving its overall performance; at the same time, the columnar structure usually has a simpler geometric shape and construction process, is easy to manufacture and install, and is easier to control and monitor quality during construction and inspection. Exemplarily, the columnar structure can be, but is not limited to, a rectangular column or a circular column.

[0034] In some embodiments, the fixing member 3 is made of fine stone concrete casting. This method is relatively simple for the production and installation of the fixing member 3. It can be directly cast and formed at the construction site, reducing the complexity and uncertainty in the production, transportation and installation process, improving the construction efficiency, and the cost of concrete is relatively low, which is conducive to reducing the overall project cost. In this embodiment, multiple PVC pipes of appropriate size and length can be used as the concrete casting mold of the fixing member 3; before casting, ensure that the inner wall of the PVC pipe is smooth without obvious bumps or stains; apply a layer of mold release agent or lubricant on the inner wall of the PVC pipe to prevent the concrete from adhering to the PVC pipe; when the PVC pipe is fixed, start casting fine stone concrete until the required height is filled; after the concrete casting is completed, use fine steel bars to vibrate and compact to ensure that the concrete is full and bubbles are removed; after the concrete is solidified, the demoulding operation can be performed to form multiple columnar plain concrete fixing members 3. The advantage of this is that the PVC pipe is easy to obtain at the construction site and is easier to operate than other materials, such as wooden boards or metal templates; at the same time, the cost of PVC pipe as a mold is low, which can effectively reduce the construction cost for large-scale production.

[0035] In some embodiments, the vertical groove 5 and the transverse groove 6 are arc grooves or rectangular grooves. In the current embodiment, arc grooves are preferably used. The edges of the arc grooves are arc-shaped and have the same shape as the steel bars. Therefore, the arc grooves are in closer contact with the surface of the steel bars, providing a larger contact area and increasing the bonding force between the steel bars and the concrete.

[0036] like Figure 3 and Figure 4As shown, in some embodiments, the fixing member 3 includes a column body 7 and a protrusion 8, and a plurality of protrusions 8 are protrudingly arranged at both ends of the column body 7. The gaps between the protrusions 8 on the same side form a vertical groove 5 or a horizontal groove 6. The length of the protrusion 8 protruding from the column body 7 is greater than the sum of the outer diameters of the vertical steel bars 1 and the horizontal steel bars 2. When the shear wall is cast, by building a shear wall formwork on both sides of the shear wall skeleton and pouring concrete, a steel bar protective layer is formed between the shear wall skeleton and the shear wall formwork. The thickness of the steel bar protective layer is the portion where the length of the protrusion 8 is greater than the sum of the outer diameters of the vertical steel bars 1 and the horizontal steel bars. The steel bar protective layer can effectively isolate the steel bars from contact with the outside world, prevent corrosive media such as oxygen and moisture from corroding the steel bar surface, thereby reducing the degree of rust on the steel bars and extending the service life of the steel bars. The overall length of the fixing member 3 is equal to the width of the shear wall and is in contact with the shear wall formwork, which can ensure that the thickness of the steel bar protective layer is consistent and increase the stability between the shear wall formwork and the fixing member 3. The consistent thickness of the steel bar protective layer can effectively avoid problems such as cracking, exposed steel bars and leakage during the use of the shear wall. Preferably, the difference between the length of the protrusion 8 and the sum of the outer diameters of the vertical steel bar 1 and the horizontal steel bar is 15 mm to 50 mm, that is, the thickness of the steel bar protective layer is 15 mm to 50 mm. Further, the gap distance between adjacent protrusions 8 is equal to the outer diameter of the vertical steel bar 1 or the outer diameter of the horizontal steel bar 2. By making the width of the groove formed between the protrusions 8 equal to the outer diameter of the steel bar, the position of the steel bar in the groove can be ensured to be more accurate, and the groove can tightly wrap the steel bar, further preventing the steel bar from shifting or misaligning, ensuring that the position and spacing of the vertical steel bar 1 and the horizontal steel bar 2 are fixed and unchanged, and avoiding the steel bar from shifting.

[0037] In some embodiments, a plurality of reinforcing ribs extending along the length direction are arranged inside the column body 7. The reinforcing ribs can effectively increase the compressive and bending bearing capacity of the column body 7, thereby improving the bearing capacity and stability of the entire shear wall structure. At the same time, the provision of the reinforcing ribs helps to reduce stress concentration and crack generation inside the column body 7, thereby improving its durability and fatigue resistance.

[0038] The present application also provides a shear wall, which includes a concrete structure, in which a shear wall frame is embedded in the concrete structure. The shear wall frame fixes the vertical steel bars 1 and the transverse steel bars 2 on both sides of the rectangular frame through a fixing member 3 with vertical grooves 5 and transverse grooves 6 at both ends. The fixing member 3 and the hook 4 are used in combination to effectively solve the problems of large manual operation errors, easy wall size deviation, steel bar misalignment and inconsistent steel bar protective layer thickness. When the shear wall is cast, the spacing between the vertical steel bars 1 and the transverse steel bars 2 is kept fixed and unchanged, and the vertical steel bars 1 and the transverse steel bars 2 do not shift. Thereby, the stability and seismic resistance of the shear wall structure are improved, the quality defects occurring during the use of the shear wall are reduced, potential safety hazards are reduced, the service life thereof is extended and the maintenance cost is reduced. At the same time, manual operation during the construction process is reduced, the construction efficiency is improved and the project cost is reduced.

[0039] The following describes in detail the shear wall skeleton and the construction process of the shear wall provided in this embodiment:

[0040] (1) Build the shear wall frame: First, at the construction site, according to the design requirements, vertical steel bars 1 and transverse steel bars 2 are arranged in a vertically staggered manner to form a rectangular frame. Hooks 4 and fixings 3 are installed at the intersections of the relative vertical steel bars 1 and transverse steel bars 2 to ensure that the spacing of the steel bars remains fixed and does not shift when the shear wall is cast later, forming a stable shear wall frame structure.

[0041] (2) Build shear wall formwork: Build shear wall formwork on both sides of the shear wall frame for subsequent concrete pouring. Shear wall formwork is usually made of wood or steel plates and installed on both sides of the shear wall frame according to design requirements. Use square steel, steel pipes, screw rods and other materials to reinforce the shear wall formwork to ensure the stability of the shear wall formwork and the integrity of the structure.

[0042] (3) Concrete pouring shear wall: After the shear wall frame and formwork are installed, concrete pouring is carried out. Concrete is usually poured into the shear wall by a concrete pump or manual pouring until the entire shear wall formwork space is filled. During the pouring process, attention should be paid to the uniformity and density of the concrete, as well as the stability of the shear wall formwork. As the concrete gradually solidifies, a vibrator can be used to vibrate the concrete surface to ensure the density and quality of the concrete. After pouring is completed, the shear wall frame can ensure that the thickness of the steel bar protective layer is consistent, avoiding quality problems such as cracking, exposed steel bars, and leakage during the shear wall process.

[0043] (4) Shear wall maintenance: After the concrete is poured, the shear wall needs to be maintained to ensure the strength and durability of the concrete. Usually, water spraying or covering with a wet cloth is used to maintain the surface of the concrete moist. The time and method of maintenance are determined according to the concrete formula and environmental conditions, and usually takes several days or weeks.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
