Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation engineering, in particular to an external frame wall connecting device and a reinforcement structure used for high thermal insulation block construction. Background Art

[0002] With the continuous improvement of building energy-saving standards, the application of thermal insulation blocks in construction projects has become more and more common. However, during the construction of thermal insulation blocks, the stability of the external frame wall faces many challenges. These challenges include the impact of block characteristics on the installation of wall ties, external environmental factors, etc. These problems may lead to construction safety hazards and quality problems.

[0003] For example, in a certain construction project, 350mm or 150mm thick insulation blocks were used for the construction of the exterior walls. According to the requirements of the "JGJ / T323-2014 Technical Specifications for the Application of Self-Insulating Concrete Composite Block Walls", double-row external scaffolding, internal scaffolding or tool-type scaffolding should be used when building insulation block walls, and scaffolding holes are not allowed to be set on the built walls. This requirement makes it difficult for the external scaffolding to connect to the wall during the construction of the insulation blocks, reducing the stability of the external frame and increasing the safety hazards of the masonry construction. Utility Model Content

[0004] The purpose of the utility model is to provide an external frame wall connection device and a reinforcement structure for the construction of high-insulation blocks, so as to solve the technical problem that the external working scaffolding is difficult to connect with the wall during the construction of the insulation blocks, resulting in reduced stability of the external frame and increased safety hazards in the construction.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an external frame wall connection device and a reinforcement structure for the construction of high-insulation building blocks.

[0006] As one aspect of the utility model, there is provided an external frame wall connection device for high-insulation block construction, comprising a steel plate, the four sides of which are fixedly connected with expansion bolts for embedding in concrete structural members, a steel pipe for connecting to a scaffolding is welded to the middle of the steel plate, and the expansion bolts and the steel pipe are in opposite directions.

[0007] By fixing the expansion bolts around the steel plate and embedding them into the concrete structure, the fixing strength and stability of the external frame wall connection device are effectively improved, ensuring the stability of the scaffolding during the construction process and reducing the safety hazards caused by the instability of the external frame.

[0008] The steel pipe welded in the middle of the steel plate provides convenience for the connection of the scaffolding, simplifies the installation process, and saves construction time and labor costs. Since the steel pipe and the expansion bolt are in opposite directions, the installation is more flexible and the operation is more convenient, which improves the construction efficiency.

[0009] The external frame connecting wall device has a reliable fixing structure, facilitating the stability of connection with concrete beams or walls and with the scaffolding, thus providing a solid guarantee for the construction of high-insulation blocks, helping to improve the masonry quality, reducing problems occurring during construction, and ensuring the project quality.

[0010] As another aspect of the present utility model, there is provided a reinforcement structure for the construction of high-insulation blocks, including high-insulation blocks attached to the outer side of concrete structural members, provided with the above-mentioned external frame connecting wall device. The external frame connecting wall device includes a steel plate pressing against the high-insulation blocks. The four sides of the steel plate are fixedly connected with expansion bolts penetrating through the high-insulation blocks and partially arranged inside the concrete structural members. A steel pipe is welded in the middle of the steel plate. On the outer side of the high-insulation blocks, there is a scaffolding composed of fixedly connected vertical poles and horizontal bars. One end of the horizontal bar is inserted into the steel pipe.

[0011] The external frame connecting wall device fixes the steel plate between the concrete structural member and the high-insulation blocks through expansion bolts, forming a stable connection, effectively enhancing the overall stability of the blocks, and reducing the risk of wall displacement or deformation.

[0012] The steel pipe welded in the middle of the steel plate provides a fixing point for the horizontal bar of the scaffolding, simplifying the connection with the scaffolding. Through the plug-in design, the horizontal bar can be quickly installed and disassembled, saving construction time and labor costs, and improving construction efficiency.

[0013] Furthermore, the high-insulation block pressed on the side includes a thermal insulation layer and a ceramsite layer. On one side of the thermal insulation layer, trapezoidal grooves are arranged at intervals. The ceramsite layer fills the trapezoidal grooves and forms a uniform covering layer on its outer side.

[0014] The thermal insulation layer and the ceramsite layer included in the structure, through the design of the trapezoidal grooves, enable the ceramsite layer to fully fill the grooves, forming a uniform covering layer, and the combination of the thermal insulation layer and the ceramsite layer is also more firm. This structural design effectively improves the thermal insulation performance of the wall, reduces the thermal bridge effect, and improves the overall energy efficiency of the building.

[0015] The external frame connecting wall device and the reinforcement structure for the construction of high-insulation blocks provided by the present utility model have the following advantages:

[0016] By drilling holes in the high-insulation blocks, the hole depth extends into the concrete member, embedding expansion bolts and installing the steel plate, welding the steel pipe for connecting the wall on the steel plate, and connecting the horizontal bar of the scaffolding. After installation, a stable connection with the external scaffolding is achieved, avoiding leaving scaffolding holes in the masonry wall, not only meeting the requirements of construction specifications, but also effectively solving the technical problem of difficult connection of the external frame and the wall in the construction of high-insulation blocks, improving the construction safety and efficiency.

[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Refer to Figures 1 to 4 , as an aspect of the present utility model, a reinforcement structure for high-insulation block construction is provided, including a high-insulation block 10 attached to the outside of a concrete structural member, provided with an external frame connecting wall device, the external frame connecting wall device includes a steel plate 33 pressing against the high-insulation block 10, and expansion bolts 31 fixedly connected around the steel plate 33 penetrate the high-insulation block 10 and are partially arranged inside the concrete structural member. A steel pipe 32 is welded in the middle of the steel plate 33. An external scaffold 40 composed of a fixedly connected vertical pole 42 and a cross bar 41 is arranged on the outside of the high-insulation block 10, and one end of the cross bar 41 is inserted inside or outside the steel pipe 32.

[0024] Among them, the depth of the expansion bolt 31 embedded in the concrete structural member is 50 mm, that is, the drilling depth is 50 mm.

[0025] The external frame connecting wall device fixes the steel plate 33 between the concrete structural member and the high-insulation block 10 through the expansion bolt 31, forming a stable connection, effectively enhancing the overall stability of the block, reducing the risk of wall displacement or deformation, and improving the seismic performance of the building.

[0026] The steel pipe 32 welded in the middle of the steel plate 33 provides a fixed point for the cross bar 41 of the scaffold 40, simplifying the connection with the scaffold 40. Through the plug-in design, the cross bar 41 can be quickly installed and disassembled, saving construction time and labor costs and improving construction efficiency.

[0027] Furthermore, an anti-corrosion coating is added at the connection between the steel plate 33 and the steel pipe 32 to extend the service life.

[0028] Furthermore, the side-pressed high-insulation block 10 includes an insulation layer 11 and a ceramsite layer 12. Trapezoidal grooves 111 are arranged at intervals on one side of the insulation layer 11, and the ceramsite layer 12 fills the trapezoidal grooves 111 and forms a uniform covering layer on its outer side.

[0029] The ceramsite layer 12 fills the trapezoidal grooves 111 and forms a uniform covering layer on its outer side, enhancing the overall structural stability of the high-insulation block 10 and avoiding the risk of material separation and shedding.

[0030] The uniformly covered ceramsite layer 12 can better maintain the heat insulation performance of the high-insulation block 10, improving the uniformity and durability of the heat insulation effect.

[0031] By providing the trapezoidal grooves 111 and the uniformly covered ceramsite layer 12, the two are easy to connect and not easy to separate, simplifying the construction process of the high-insulation block 10, reducing the operation steps, and improving the construction efficiency and convenience.

[0032] Furthermore, adding a reflective film or a heat-insulating film between the insulation layer 11 and the ceramsite layer 12 can further enhance the heat insulation performance. This film can effectively reflect heat, reduce the heat transfer through the insulation layer 11, and improve the overall heat insulation effect.

[0033] Refer to Figures 1 to 3 , the present utility model provides an external frame connecting wall device for the construction of the high-insulation block 10, including a steel plate 33. Expansion bolts 31 for embedding in concrete structural members are fixedly connected around the steel plate 33. A steel pipe 32 for connecting with the scaffold 40 is welded in the middle of the steel plate 33. The expansion bolts 31 and the steel pipe 32 face in opposite directions.

[0034] By fixedly connecting the expansion bolts 31 around the steel plate 33 and embedding them in the concrete structural members, the fixing strength and stability of the external frame connecting wall device are effectively improved, ensuring the stability of the scaffold 40 during the construction process and reducing the potential safety hazards caused by the instability of the external frame.

[0035] The steel pipe 32 welded in the middle of the steel plate 33 provides convenience for the connection of the scaffold 40, simplifies the installation process, and saves construction time and labor costs. Since the steel pipe 32 and the expansion bolts 31 face in opposite directions, it is more flexible and convenient to install, improving the construction efficiency.

[0036] The external frame connecting wall device has a reliable fixing structure, facilitating the stability of the connection with the concrete beam or wall and with the scaffold 40, thus providing a solid guarantee for the construction of the high-insulation block 10, helping to improve the masonry quality, reducing the problems occurring during the construction process, and ensuring the project quality.

[0037] Among them, the specification of the expansion bolt 31 is M8*200mm, and the thickness of the steel plate 33 is 3mm.

[0038] In one embodiment, a number of reinforcing ribs are added to the steel plate 33 to form a grid structure, improving the overall rigidity and bending resistance of the steel plate 33.

[0039] A waterproof sealing washer is added outside the expansion bolt 31 to prevent rainwater from seeping in and extend the service life of the connection part.

[0040] In one embodiment, anti-slip lines or rubber sheaths are added to the outside of the steel pipe 32 to increase the friction force, prevent the connection part from sliding, and ensure construction safety.

[0041] The edge of the steel plate 33 is chamfered to avoid sharp edges from causing harm to construction workers and improve safety.

[0042] Construction method

[0043] Drill holes in the high-insulation block 10 to a depth of 50mm into the concrete member 20, then embed the expansion bolt 31, install the 3mm-thick steel plate 33 and weld the steel pipe 32 for connecting to the wall on the steel plate 33, and connect it to the cross bar 41 of the external scaffold.

[0044] The external scaffold connection device and reinforcement structure for high-insulation block construction provided by the present utility model have the following advantages:

[0045] After the device is installed, it avoids leaving scaffold holes in the masonry wall during the construction of high-insulation blocks, resulting in the non-compliance of high-insulation block construction with the specification requirements, and well solves the problem of difficult connection of the external scaffold.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
