Description

Technical Field

[0001] The utility model relates to the technical field related to construction, in particular to a sill wall footing structure. Background Art

[0002] Metal-faced sandwich panels, as a decorative, thermally insulating, and heat-insulating enclosure, are widely used in the exterior cladding of industrial plants, logistics buildings, and office buildings due to their attractive appearance, excellent sealing, and cost-effectiveness. However, because the core materials of metal-faced sandwich panels are often rock wool or glass wool, their inherent moisture-proofing properties are relatively poor, limiting their application to walls above ground level. Typically, a sill wall is installed below ground level and within a certain extension, typically in reinforced concrete or masonry walls. The metal-faced sandwich panel and the sill wall need to be fixed and sealed and waterproof. The existing technology has the problem of complex connecting member structure, large number of accessories, and complicated installation, which is not conducive to construction. As a result, the metal-faced sandwich panel is either not firmly fixed or the sealing performance is poor even if it is firmly fixed. To solve the above problems, Chinese patent document with publication number CN218346472U discloses a connection and fixing structure between the metal-faced sandwich panel and the building wall skirt, which includes a moisture-proof wall, a wall purlin, an angle piece, a self-tapping screw, and a limit rod connected to the outer side of the limit frame. The angle piece is fixed to the moisture-proof wall by expansion bolts. The self-tapping screw extends from the inner side of the wall purlin and is threadedly connected to the angle piece. A limit rod capable of fixing the self-tapping screw is fixed inside the wall purlin. After the angle piece and the wall purlin are fixed, the tongue-and-groove end of the metal-faced sandwich panel is inserted into the top of the angle piece to fix the metal-faced sandwich panel. Finally, glue is applied to the contact between the angle piece and the moisture-proof wall to seal. Although it can fix the sandwich panel and the sill wall and ensure the sealing of the connection, it has the following disadvantages: first, this structure is only applicable to the horizontal installation method of the sandwich panel with the tongue and groove facing downward, and is not applicable to the vertical installation method of the sandwich panel with the tongue and groove facing the side. The sandwich panel cannot be fixed and installed and sealed by using special-shaped corner pieces, and the scope of application is relatively narrow; second, since the upper end of the part where the special-shaped corner piece protrudes from the lower end of the sandwich panel is a plane, the tongue and groove of the sandwich panel and the plane are still easy to get water in, the sealing effect is poor, and the service life of the sandwich panel will be greatly reduced; most importantly, because the folding size of the lower end of the special-shaped corner piece facing the moisture-proof wall must be determined after the actual thickness of the sill wall and the positional relationship between the sill wall and the wall sandwich panel are determined, the waterproof component can be processed and manufactured. There are many restrictions on manufacturing, processing, installation and use, which seriously affect the construction period and applicable occasions and cannot meet actual needs. Summary of the Invention

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1:

[0018] According to the instruction manual Figure 1As shown in the figure, the utility model provides a structure for the lintel of a parapet wall, which includes a parapet wall base 1, a wall sandwich panel 2, a parapet wall purlin 3, a flashing 4, a hanger strip 5 and a lintel buckle plate 6. A parapet wall purlin 3 is fixedly connected to the upper part of the parapet wall base 1. The wall sandwich panel 2 is arranged above the parapet wall base 1 and is fixedly installed on the parapet wall purlin 3 by screws. The rear side of the wall sandwich panel 2 presses against the front side of the parapet wall purlin 3. The flashing 4 is formed by continuously bending a sheet and is in a Z shape, successively including a flashing vertical section 401, a flashing horizontal section 402 and a flashing overhanging section 403. The flashing vertical section 401 is located between the wall sandwich panel 2 and the parapet wall purlin 3. The flashing horizontal section 402 is located at the lower end of the wall sandwich panel 2. The flashing overhanging section 403 protrudes from the outer surface of the parapet wall base 1 and forms an overhanging gap 7 with the outer surface of the parapet wall base 1. The hanger strip 5 is formed by bending a sheet and is in an L shape. The hanger strip 5 includes a hanger vertical side plate 501 and a hanger horizontal side plate 502. The hanger vertical side plate 501 is fixed closely to the wall sandwich panel 2. There is a hanger horizontal side plate 502 extending forward in the horizontal direction along the upper side of the hanger vertical side plate 501 to the wall sandwich panel 2. A lintel buckle plate 6 with a cross-section in the shape of a C or L or J is fixedly installed between the hanger horizontal side plate 502 and the flashing overhanging section 403. The upper part of the lintel buckle plate 6 is provided with a buckle upper flat section 601 and is clamped at the upper end of the hanger horizontal side plate 502. The lower part of the lintel buckle plate 6 is provided with a buckle upward section 604 and is clamped at the rear side of the flashing overhanging section 403. The wall sandwich panel 2 is fixed to the parapet wall purlin 3 by self-tapping screws in an existing conventional manner. The flashing 4 is designed as a bending part, with strong on-site adjustability, and serves as the lower buckling point for fixing the lintel buckle plate 6. During the later installation, the vertical inclination angle of the flashing overhanging section 403 can also be actually adjusted according to the on-site situation, which is convenient for adjusting and then matching the installation of the lintel buckle plate 6. The lintel buckle plate 6 is formed by bending a metal plate with good elasticity and can be quickly and conveniently buckled on the flashing 4 and the hanger strip 5 during installation, making it more convenient to use.The utility model can effectively ensure the waterproof seal at the junction of the sandwich panel and the sill wall through the flashing member 4, the hanging rack strip 5 and the foot gusset plate 6. It is not only suitable for the horizontal installation method of the sandwich panel with the tongue and groove facing downwards, but also suitable for the vertical installation method of the sandwich panel with the tongue and groove facing the side. It can not only ensure the airtightness within the building unit and prevent the occurrence of condensation water indoors, but also effectively avoid the problem that the sandwich panel cannot be used normally after being soaked due to the backflow of outdoor rain and snow water. When making and processing related waterproof components, it is only necessary to consider the thickness specifications and installation position of the wall sandwich panel 2, without considering the actual thickness of the sill wall base 1. The size and position are suitable for the actual on-site conditions of various sill walls. They can be used in situations where the actual thickness of the sill wall is determined or where the actual thickness of the sill wall is uncertain. The actual processing and manufacturing of sill wall waterproof components is more convenient and quick, the installation is more flexible, and the appearance applicability is stronger. It takes into account both its waterproof performance and the sill wall construction conditions for different situations, is easy to operate and install, and is conducive to the unity of the overall installation project. It has a short construction period, a wide range of applications, good sealing effect, easy disassembly and assembly, a neat appearance, and a good overall appearance effect. It is safe, reliable, durable, and energy-efficient.

[0019] The base plate 6 is formed by continuously bending a plate, which consists of a flat section 601 on the plate, a front vertical section 602 of the plate, a lower inclined section 603 of the plate and a raised section 604 on the plate. The flat section 601 on the plate is placed on the upper end of the horizontal side plate 502 of the hanger and is fixed to the horizontal side plate 502 of the hanger by rivets. The front vertical section 602 of the plate is located in front of the hanger bar 5, the lower inclined section 603 of the plate is located below the flashing suspension section 403, and the raised section 604 on the plate is located in the suspension gap 7. The front side of the raised section 604 on the plate presses the rear side of the flashing suspension section 403. The flat section 601 of the gusset plate is fastened to the upper end of the horizontal side plate 502 of the hanger and fixed with rivets, so that rainwater will not flow to the lower end of the wall sandwich panel 2. Through the lower inclined section 603 of the gusset plate and the raised section 604 of the gusset plate, and the raised section 604 of the gusset plate is fastened to the flashing hanging section 403, rainwater will not flow into the gap between the wall sandwich panel 2 and the sill wall base 1, thereby avoiding the problem of water seepage at the joint and ensuring the service life of the wall sandwich panel 2. At the same time, the foot gusset plate 6 can cover the gap between the wall sandwich panel 2 and the sill wall base 1, making the appearance of the wall sandwich panel 2 more beautiful after installation.

[0020] Example 2:

[0021] As attached Figure 1 As shown, the difference between this embodiment and Example 1 is that the lower inclined section 603 of the gusset plate is arranged in an inclined direction with a lower front and a higher rear. The inclined angle ɑ between the lower inclined section 603 and the front vertical section 602 of the gusset plate is between 45° and 80°. By arranging the lower inclined section 603 in the direction with a lower front and a higher rear, it can effectively block rain and snow and prevent rain and snow water from flowing along the lower inclined section 603 to the wall base 1, thereby improving the waterproof effect.

[0022] Example 3:

[0023] As attached Figure 1 As shown, the difference between this embodiment and embodiment 1-2 is that the wall sandwich panel 2 is a vertical wall sandwich panel 2, the long side of the wall sandwich panel 2 is placed on the sill wall base 1, and the horizontal flashing section 402 is installed between the long side of the wall sandwich panel 2 and the sill wall base 1.

[0024] Example 4:

[0025] As attached Figure 2 As shown, the difference between this embodiment and embodiments 1-3 is that the wall sandwich panels 2 are horizontal wall sandwich panels 2, and the wall sandwich panels 2 are placed on the sill wall base 1 through the tongue and groove, and the wall panel support members 8 are installed in the tongue and groove. The wall sandwich panels 2 are fixed to the sill wall purlins 3 through the wall panel support members 8 and self-tapping screws, and the tongue and groove of the wall sandwich panels 2 are provided with insulation material 9, and the flashing horizontal section 402 is installed between the tongue and groove side of the wall sandwich panels 2, the insulation material 9 and the sill wall base 1.

[0026] Example 5:

[0027] As attached Figure 2 As shown, the difference between this embodiment and embodiments 1-4 is that the thermal insulation material 9 is thermal insulation rock wool. Thermal insulation rock wool can reliably fill the wall panel gap 5. It also has a certain elasticity and can adapt to deformation of the wall panel gap 5, achieving thermal insulation and high fire safety. Thermal insulation rock wool has stable physical properties, is lightweight, high strength, non-flammable, moth-proof, corrosion-resistant, has excellent thermal insulation, heat preservation, and sound insulation properties, and is easy to install and has good results.

[0028] The wall panel support members 8 are made of galvanized steel. During actual manufacturing, the length and bend dimensions of the wall panel support members 8 are determined based on the tongue-and-groove configuration and bulk density of the wall sandwich panel 2. Hot-dip galvanized steel sheets of varying thicknesses are used for press-forming to secure the wall sandwich panel 2 at its tongue-and-groove position and prevent it from moving.

[0029] Example 6:

[0030] As attached Figure 1-2 As shown, the difference between this embodiment and embodiments 1-5 is that a weather-resistant silicone sealant is applied to the joint between the end of the flat section 601 of the gusset plate and the outer side of the wall sandwich panel 2. By applying sealant to the joint between the end of the flat section 601 of the gusset plate and the wall sandwich panel 2, the waterproof sealant at the joint can be further improved, resulting in a better waterproof effect.

[0031] The installation process of the present invention is as follows: First, fix the sill wall purlin 3 to the upper end of the sill wall base 1, and install and fix the wall sandwich panel 2 and the flashing member 4 on the sill wall purlin 3. The thickness of the flashing member 4 is recommended not to exceed 0.6mm. Too thick is not conducive to adjustment and is not conducive to the buckling of the plinth gusset plate 6; secondly, according to the on-site construction progress, fix the hanging rack 5 on the wall sandwich panel 2. The position and height can be determined according to the actual measurement of the on-site conditions. Pay attention to the direction of the hanging rack 5 during installation. The thickness of the hanging rack 5 should not be less than 0.5mm; then After the flashing parts 4 and the hanging rack strips 5 are installed, the size of the footing gusset plate 6 can be measured. When installing the footing gusset plate 6, pay attention to first make the upper section 604 of the gusset plate extend from the overhanging gap 7, buckle the flashing overhanging section 403 of the flashing parts 4 from the bottom, and then buckle the flat section 601 of the footing gusset plate 6 on the top of the hanging rack horizontal side plate 502 of the hanging rack strip 5, and then fix the flat section 601 on the gusset plate to the hanging rack horizontal side plate 502 by rivets; finally, the joint between the end of the flat section 601 on the gusset plate and the wall sandwich panel 2 is waterproofed with glue.
