Description

Technical Field

[0001] The invention relates to the technical field of in-mold injection molding building structures, and in particular to a method for manufacturing a flat plate type deformation joint for a parking structure. Background Art

[0002] Deformation joints are a general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the influence of external factors, leading to cracks or even damage. Deformation joints are structural joints reserved for this situation.

[0003] Expansion joint: Building components will expand and contract due to changes in temperature and humidity. For this reason, vertical gaps are usually set at appropriate locations of the building to disconnect the walls, floor slabs, roofs and other components of the building from the foundation, separating the building into several independent parts. The gaps set to overcome excessive temperature differences do not need to be disconnected from the foundation top surface to the roof structure.

[0004] Seismic joints: Joints set up to make buildings more regular and to help the structure resist earthquakes. The foundation can be continuous. Its purpose is to separate large buildings into smaller parts, forming relatively independent earthquake-resistant units, to avoid damage caused by uncoordinated vibrations of the entire building due to earthquakes.

[0005] Settlement joint: refers to the joints in the building structure set up to avoid uneven settlement and cracking of the wall or other structural parts when the height of the same building is very different, the upper load is unevenly distributed, or it is built on different foundation soils. Settlement joints divide the building into several sections, forming a self-contained system, from the foundation, wall, floor to the roof, which are not connected. The width of the joint is generally 70-100 mm. It is a vertical joint that completely divides the building or structure into sections from the foundation to the top. It is used to avoid cracks caused by uneven settlement of each section. It is usually set between parts of the building with very different heights, loads or foundation bearing capacities, as well as at the junction of new and old buildings.

[0006] In the prior art, the patent application number is: CN201921376514.1; the patent name is: A building structure deformation joint installation structure; a building structure deformation joint installation structure is disclosed, including a structural floor and a deformation joint structural beam, wherein the deformation joint structural beam has a deformation joint, and structural grooves are provided at the upper and lower parts of the deformation joint, and a first deformation joint expansion steel plate and a second deformation joint expansion steel plate are fixedly connected in the upper and lower structural grooves respectively, and a drainage pipe is arranged in the deformation joint, and the first deformation joint expansion steel plate and the second deformation joint expansion steel plate both have a notch sunken into the deformation joint to form a drip line.

[0007] Although the prior art discloses a deformation joint installation structure, the installation structure in the prior art only sets the deformation joint in the deformation joint structural beam between the structural floor slabs. Although a drainage pipe is set in the deformation joint, which has a certain drainage capacity, it does not ensure the two-way free displacement performance of the buildings on both sides.

[0008] With the development of cities, there are more and more above-ground parking buildings and their scale is getting larger and larger. It is inevitable that there will be expansion joints in the parking building structure. The expansion joints of the parking building must ensure that the buildings on both sides can move freely in both directions horizontally, have good waterproof effects, and can meet the smooth passage of vehicles, and be easy to install and maintain.

[0038] Embodiment 1

[0039] like Figure 1 , Figure 2 As shown, a flat plate deformation joint structure for a parking structure includes a structural plate 1 of the parking structure and a structural plate 2 2 adjacent thereto, wherein a deformation joint is arranged between the structural plate 1 and the structural plate 2 2.

[0040] The deformation joints arranged between the structural plate 1 and the structural plate 2 include the expansion joints between the structural plate 1 and the structural plate 2. An expansion joint installation space is reserved on the side of the structural plate 1 and the structural plate 2 near the expansion joint, that is, a concave mounting platform 13 is arranged on the end of the structural plate 1 and the structural plate 2 near the expansion joint. The F-shaped steel 3 arranged on the mounting platform 13 on both sides of the contraction joint is fixed in the structural plate 1 and the structural plate 2 on both sides by anchoring steel bars 11. The expansion joint cover plate is fixed on the top of the F-shaped steel 3 on one side as the fixed end of the cover plate, and the F-shaped steel 3 on the other side is not connected to the expansion joint cover plate and serves as the sliding end of the expansion joint cover plate.

[0041] Specifically, a pair of F-shaped steels 3 are relatively embedded on the mounting platform 13 of the structural plate 1 and the structural plate 2 2 on both sides of the longitudinal center axis of the deformation joint. The middle notches of the cross sections of the pair of F-shaped steels 3 are all facing the longitudinal center axis of the deformation joint. A waterstop 4 is arranged between the relatively arranged F-shaped steels 3, and the waterstop 4 is embedded in the notch of the F-shaped steel 3 near the side edge of the F-shaped steel 3. The cross-sectional view of the waterstop 4 is a W-shaped structure, but it is not limited thereto. In other embodiments, waterstops of other structures can also be used.

[0042] Specifically, an expansion joint cover plate is arranged across the structure plate 1 and the structure plate 2, and one end of the expansion joint cover plate is fixedly connected to the F-shaped steel 3 on one side; the F-shaped steel 3 on the other side and the expansion joint cover plate are movably installed through a sliding plate 8. More specifically, the expansion joint cover plate includes a steel plate 5 that spans the F-shaped steel 3 of the structure plate 1 and the structure plate 2, and a stainless steel patterned panel 7 that covers the steel plate 5; a rubber pad 6 is also arranged between the panel 7 and the steel plate 5.

[0043] Further, one end of the steel plate 5 fixedly mounted with the F-shaped steel 3 on the structural plate 1 is the fixed end, and the other end of the steel plate 5 slidingly mounted with the F-shaped steel 3 on the structural plate 22 through the sliding plate 8 is the sliding end. The steel plate 5 is fixed to the F-shaped steel 3 on one side by perforated plug welding, and the other end of the expansion joint cover is laid flat on the structural plate 1 and the structural plate 22 of the parking building. A polytetrafluoroethylene sliding plate 8 is arranged between the expansion joint cover and the structural plate 22 at the sliding end. An inclined placement angle steel 10 is arranged at the end where the sliding plate 8 is slidably connected to the expansion joint cover and the height difference connection with the structural plate 1 or the structural plate 22. Further, an inclined placement angle steel 10 is arranged on one side of the mounting platform on the structural plate 22 away from the structural plate 1. The expansion joint cover and the structural plate 22 of the structural plate 22 can slide horizontally with each other, and a galvanized placement angle steel 10 is arranged at the far end of the sliding surface, which is placed at an angle α with the floor; α is 35°~55°. The upper supporting surface formed by the expansion joint cover plate, the structural plate 1 1 and the structural plate 2 2 connected and installed is on the same horizontal plane.

[0044] When the instantaneous deformation is large, the galvanized angle steel 10 guides the expansion joint cover to slide out along the inclination without causing damage to the structural components. The flat expansion joint method has a wide range of application requirements for horizontal displacement and a wide range of application for expansion joint width.

[0045] But it is not limited to this. In other embodiments, one end of the steel plate 5 that is fixedly installed with the F-shaped steel 3 on the parking building structure 2 can be the fixed end, and one end of the steel plate 5 that is slidably installed with the F-shaped steel 3 on the structural plate 1 through the sliding plate 8 can be the sliding end.

[0046] Embodiment 2

[0047] Based on the first embodiment, Figure 1 , Figure 2 As shown, the included angle between the positive angle of the angle steel 10 and the floor of the parking building is α, and α is 45°.

[0048] The two interconnected parking structures reserve space for expansion joint installation and additional steel bars 12. The reserved width should be sufficient for the anchoring depth of the steel bars. Full-length F-shaped steel 3 is set on both sides of the expansion joint. The back of the F-shaped steel 3 is welded to the anchor steel bars 11 every 250 mm. After adjusting the elevation of the F-shaped steel 3, it is filled with grouting material and fixed to the structural plates on both sides.

[0049] The expansion joint cover is fixed on the top of the F-shaped steel 3 on one side, serving as the fixed end of the expansion joint cover. The F-shaped steel 3 on the other side is not connected to the expansion joint cover, serving as the sliding end of the expansion joint cover. The flexible rubber water stop 4 is inserted into the internal notch of the F-shaped steel 3 cross section.

[0050] The expansion joint cover is composed of a steel plate 5, a rubber pad 6 and a stainless steel pattern panel 7. The steel plate 5 is fixed to the F-shaped steel 3 on one side by perforated plug welding; the other end of the steel plate 5 is laid flat on the structural plate 2 2 of the parking building and can slide freely horizontally. The sliding surface between the steel plate 5 and the structural plate 2 2 is paved with a polytetrafluoroethylene sliding plate 8. The stainless steel pattern panel 7 is fixed with self-tapping screws. After installation, it is at the same height as the structural plates 1 1 and 2 2 on both sides, which can meet the requirements of smooth passage of vehicles.

[0051] More specifically, taking a 150mm wide expansion joint as an example, the required steel plate 5 thickness for this expansion joint width is about 10mm, the rubber pad 6 thickness is about 2mm, the stainless steel patterned panel 7 thickness is about 3mm, and the polytetrafluoroethylene sliding plate 8 thickness is about 3mm. The anchoring elevation of the fixed end F-shaped steel 3 should be 15mm lower than the floor elevation, which is the sum of the thickness of the steel plates 5, 6, and the stainless steel patterned steel plate 7; the anchoring elevation of the sliding end F-shaped steel 3 should be 18mm lower than the floor elevation, which is the sum of the thickness of the steel plate 5, rubber pad 6, stainless steel patterned steel plate 7, and polytetrafluoroethylene sliding plate 8. At the same time, the reserved sliding surface structural plate should be consistent with the elevation of the F-shaped steel 3 on this side, and the grouting material finish surface should be 18mm lower than the floor elevation. If it is an expansion joint of other sizes, the thickness of the steel plate needs to be adjusted.

[0052] The fixed end of the expansion joint is equipped with vertical galvanized edge protection angle steel 9, and the grouting material is poured to the floor elevation and maintained; the other side is the sliding end of the expansion joint, and the far end of the sliding surface is connected with a galvanized placement angle steel 10 placed at a 45° angle with the floor as the galvanized edge protection angle steel 9, and also as a template for the connection between the sliding surface and the structural plate when the grouting material is poured. When the deformation exceeds the range of the sliding surface, the expansion joint cover plate can slide out along the chamfer produced by the galvanized placement angle steel 10. Additional steel bars 12 should be pre-embedded in the area of ​​grouting material poured after the structural plates on both sides of the expansion joint to enhance the strength and integrity of the structural plates here.

[0061] Step 4, insert the water stop strip 4 into the cross-sectional notch of the relatively arranged F-shaped steel 3;

[0062] Step 5: Install the expansion joint cover.

[0063] Specifically, the expansion joint cover is composed of a steel plate 5, a rubber pad 6 and a stainless steel patterned panel 7. The steel plate 5 is fixed to the F-shaped steel 3 on one side by perforated plug welding. The other end of the expansion joint cover is laid flat on the structural plate 1 and the structural plate 2 2 of the parking building. A polytetrafluoroethylene sliding plate 8 is arranged between the expansion joint cover and the structural plate 2 2 at the sliding end, so that the expansion joint cover and the main structural plate of the structural plate 2 2 can slide horizontally relative to each other. A galvanized placement angle steel 10 is arranged at the far end of the sliding surface and is placed at an angle α with the floor.
