Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a column formwork wall structure with earthquake-resistant performance. Background Art

[0002] With the acceleration of urbanization and the increasing number of high-rise buildings, the seismic performance of building structures has become a major issue concerning the safety of people's lives and property and social stability. As a widely used building structure, the research and improvement of the seismic performance of column formwork wall structure is particularly important. Column formwork wall structure usually refers to a wall system constructed by column formwork and wall materials, in which the column formwork plays the role of support, positioning and connection, while the wall material provides enclosure, separation and partial or full load-bearing function. However, the current column formwork wall structure still has some inherent defects in seismic performance, mainly including the following aspects: First, the connection nodes between the column formwork and the wall, and between the wall and the wall are weak, which may cause the nodes to be damaged before the main structure under the action of the earthquake, affecting the overall seismic performance of the wall structure. Repair and upgrading are difficult. Once a building is damaged by an earthquake, the repair or upgrade work is often complicated and costly, and seismic reinforcement work is particularly difficult.

[0003] The Chinese patent document in the prior art: 201510360373.4 discloses a modular earthquake-resistant and heat-insulating integrated straw composite wood structure house, including a wall and a floor formed by a plurality of panel units being plugged into each other on the left and right sides, the floor being located on the upper end of the wall below it and connected by mortise and tenon joints, and the lower end of the wall above the floor being connected to a metal connector; or the upper wall being connected to a metal pipe column passing through the floor, and the lower end of the base wall being connected to a metal embedded part; a roof panel is installed on the upper end of the top wall; the panel unit includes a composite core board, and the composite core board includes a non-glue straw board.

[0004] However, during the implementation of the above scheme, there are at least the following technical problems: First, metal connectors, metal pipe columns and mortise and tenon joints provide structural connections for the house, but under the action of strong earthquakes, the pull-out, shear and torsion resistance of this type of connection method is not enough to ensure the stability and continuity of the structure. Secondly, as an environmentally friendly material, the glue-free straw board has certain thermal insulation properties, but when it is subjected to gravity loads, wind loads and earthquakes, the mechanical properties of the glue-free straw board are insufficient. In addition, the fire resistance of straw composite materials is relatively low. Once a fire occurs, it is easy to cause the fire to spread rapidly, posing a threat to the lives of residents. Therefore, it is urgent to propose a column formwork wall structure with earthquake resistance. Summary of the invention

[0005] In view of the above technical problems, the present invention provides a column formwork wall structure with seismic resistance, which solves the technical problems in the prior art of insufficient stability of building structure connections, low safety performance under extreme conditions such as earthquakes, and limited mechanical properties.

[0006] According to one aspect of the present disclosure, there is provided a column-form wall structure with earthquake resistance, comprising a ground beam, a plurality of columns installed above the ground beam, at least two column grooves arranged on the sides of the columns, a concrete stabilizing structure is cast in a ground beam cavity formed by the ground beam and in the column grooves; wall panels are installed between the columns, wall panel grooves connected to the columns are arranged on both sides of the wall panels, a concrete stabilizing structure is cast in the wall panel grooves, the wall panels comprise inner wall panels and outer wall panels attached to both sides of the inner wall panels, the height of the inner wall panels is lower than the height of the outer wall panels, the width of the inner wall panels is smaller than the width of the outer wall panels, a plurality of threading holes are arranged through the inner wall panels in a vertical direction, noise reduction components are arranged in the threading holes, a wiring groove for placing pipelines is arranged above or below the wall panels, the outer wall panels comprise an insulation layer connected to the inner wall panels, and a protective layer is connected to the outer side of the insulation layer; a ring beam is arranged above the columns, a concrete stabilizing structure is cast in a ring beam cavity formed by the ring beam.

[0007] The ground beam and the column are connected by steel bar binding; the ring beam and the column are connected by steel bar binding.

[0008] The inner wall panel and the insulation layer are connected via a thermal break connector, and the insulation layer and the protective layer are connected via a thermal break connector; the thermal break connector includes a long strip with a rectangular cross section.

[0009] The thermal insulation layer comprises a thermal insulation material having a thermal conductivity lower than 0.05 W / (m·K).

[0010] The insulation layer includes ESP XPS rock wool insulation board, and the protective layer includes concrete material.

[0011] The upright column is an L-shaped column and / or a T-shaped column and / or a X-shaped column.

[0012] The L-shaped column includes two grooves arranged on the side, the T-shaped column includes three grooves arranged on the side, and the X-shaped column includes four grooves arranged on the side.

[0013] A noise reduction component is arranged in the threading hole, and the noise reduction component includes a plurality of sound insulation components and sound absorbing components arranged at intervals along the inner wall of the threading hole.

[0014] The beneficial effects of the utility model are:

[0016] The wall panels adopt a composite structure of inner wall panels and outer wall panels on both sides. The outer wall panels are embedded with ESP XPS rock wool insulation panels, which have extremely low thermal conductivity, significantly reduce heat transfer, and achieve efficient thermal insulation performance.

[0017] The concrete protective layer set on the outside of the insulation layer not only protects the insulation layer from the influence of the external environment and extends its service life, but also enhances the weather resistance and fire resistance of the wall.

[0018] The inner wall panels are provided with threading holes, and noise reduction components are arranged in the threading holes. The sound insulation board body forms a multi-level sound insulation barrier to effectively block the propagation of sound.

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example 1

The wall panel 5 includes an inner wall panel 7 and an outer wall panel 8 attached to both sides of the inner wall panel 7, the height of the inner wall panel 7 is lower than the height of the outer wall panel 8, the width of the inner wall panel 7 is smaller than the width of the outer wall panel 8, and a plurality of threading holes 9 are arranged through the inner wall 7 along the vertical direction, and a noise reduction component 10 is arranged in the threading hole 9, a wiring groove 11 for placing pipelines is arranged above or below the wall panel 5, and the outer wall panel 8 includes an insulation layer connected to the inner wall panel 7, and the outer side of the insulation layer is connected to the protective layer; a ring beam 12 is arranged above the column 2, and a concrete stable structure is cast in the ring beam cavity 13 formed by the ring beam 12.

[0031] The ground beam 1 and the column 2 are connected by steel bar binding; the ring beam 12 and the column 2 are connected by steel bar binding.

[0032] The inner wall panel 7 is connected to the thermal insulation layer via a thermal break connector, and the thermal insulation layer is connected to the protective layer via a thermal break connector; the thermal break connector includes a long strip with a rectangular cross section.

[0033] Thermal break connectors are an engineering component that solves the thermal bridge effect in building envelope structures. At the junction of different materials, they cut off or significantly reduce the direct transfer of heat through their own low thermal conductivity characteristics, thereby improving the thermal insulation performance of the overall envelope structure.

[0034] The thermal insulation layer comprises a thermal insulation material having a thermal conductivity lower than 0.05 W / (m·K).

[0035] The insulation layer includes ESP XPS rock wool insulation board, and the protection layer includes concrete material.

[0036] The upright column 2 is an L-shaped column 14 and / or a T-shaped column 15 and / or a X-shaped column 16 .

[0037] The L-shaped column 14 includes two column grooves 3 arranged on the side, the T-shaped column 15 includes three column grooves 3 arranged on the side, and the X-shaped column 16 includes four column grooves 3 arranged on the side.

[0038] A noise reduction component 10 is arranged in the threading hole 9, and the noise reduction component 10 includes a plurality of sound insulation components and sound absorbing components arranged at intervals along the inner wall of the threading hole 9. The sound insulation component includes a multi-stage sound insulation board body 17 connected end to end, and the sound absorbing component is embedded in a cavity formed by the threading hole 9 and the sound insulation board body 17.

[0039] The sound insulation piece is connected to the inner side of the threading hole 9 by welding, and the sound absorbing piece is connected to the inner side of the threading hole 9 by gluing.

[0040] The sound insulation board 17 includes a first board 18, a second board 19 and a third board 20 which are connected end to end in a Z-shape. The end of the first board 18 is connected to the inner side of the threading hole 9, and the end of the third board 20 is suspended.

[0041] The sound absorbing member includes sound absorbing cotton, and a gap is left between the sound absorbing cotton and the sound insulation board body, and the gap between the sound absorbing cotton and the sound insulation board body 7 gradually decreases from the end of the sound insulation board body 7 to the inner side of the threading hole 3.

[0042] During the work process, the column formwork wall structure is designed according to the structural requirements of the building and the pipeline layout planning. Determine the dimensions of the ground beam, column type (including L-shaped column, T-shaped column, X-shaped column), wall panel, and ring beam. First, the ground beam is positioned and installed. The column is hoisted in place according to the designed position and connected to the ground beam by steel bar binding to form a stable frame structure. Then the ground beam is cast. When the ground beam solidifies to a certain strength, concrete is poured in the groove of the column. The wall panels are installed one by one in sequence. Concrete is also poured in the groove of the wall panel to ensure the close connection between the wall panel and the column. The inner wall panel and the insulation layer, and the insulation layer and the protective layer are fixed by broken bridge connectors to ensure thermal performance and structural strength. The ring beam is installed on the top of the column according to the designed position, connected to the column by steel bar binding, and concrete is poured in the cavity of the ring beam to enhance the overall seismic performance.

[0043] During the operation of the noise reduction component, the multi-stage sound insulation board 7 connected end to end in the sound insulation has a guiding effect. The gap between the sound-absorbing cotton and the sound insulation board 7 gradually decreases from the end of the sound insulation board 7 to the inside of the threading hole 3. When the sound wave passes through this structure, due to the change in the gap size, the sound wave will experience multiple reflections and refractions through the guiding effect of the sound insulation, which increases the contact time between the sound wave and the sound-absorbing cotton, allowing the sound wave to be transmitted to the position of the sound absorbing component and absorbed, effectively reducing the diffusion of noise, thereby further improving the noise absorption efficiency of the sound absorbing component. The sound insulation is firmly connected to the inside of the threading hole 3 by welding, ensuring the stability and sound insulation effect of long-term use; the sound absorbing component is connected to the inside of the threading hole by gluing, which not only maintains the stability of the connection, but also allows a certain degree of elastic deformation, which is conducive to the sound absorbing cotton to fully exert its sound absorption performance.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.
