Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a waterstop steel plate positioning module for raft concrete construction. Background Technology
[0002] A raft foundation is a type of monolithic reinforced concrete foundation used in building construction. Also known as a raft base, it essentially forms the "footing" of a building as a continuous, thick slab, evenly distributing the load of the superstructure to the ground. It is a type of shallow foundation. Its main applications include: 1. When the bearing capacity of the foundation is low (such as soft soil foundation), and isolated foundations or strip foundations cannot meet the bearing capacity requirements; 2. When the building has a large load (such as high-rise buildings, large shopping malls, basements) and the load needs to be distributed over a large area; 3. When the soil layers are unevenly distributed, uneven settlement is likely to occur, and it is necessary to enhance the overall integrity of the foundation; 4. When the groundwater level is high and the building needs to also serve as an anti-buoyancy base slab; A Chinese patent document with publication number CN106939612A discloses a construction method for a large raft foundation, the scheme of which includes the following steps: Step (1), cutting the columns and base, and welding the base to the bottom of the columns; Step (2), binding the bottom reinforcement, arranging the columns, and then welding the base to the bottom reinforcement; Step (3), horizontally welding the middle connecting beam to the middle of the columns; Step (4), supporting diagonal bracing only between adjacent columns on the outer side; Step (5), binding the middle reinforcement, and welding the middle reinforcement to the middle connecting beam mentioned in the step; Step (6), horizontally welding the upper crossbeam to the top of the columns; Step (7), binding the upper reinforcement, and welding the upper reinforcement to the upper crossbeam; Step (8), pouring concrete; However, in existing technologies, due to the large size and area of large raft foundations, they need to be poured in stages during construction. However, in traditional pouring methods, the concrete in different areas is not poured in one go, resulting in a low degree of bonding at the joints, which can easily lead to the risk of water seepage later. The existing technology usually addresses this risk by adding a water-stop steel plate structure between the concrete structures poured in different batches. However, the traditional method of positioning the water-stop steel plate requires a separate installation structure, which can affect the construction efficiency to some extent. Therefore, this invention proposes a water-stop steel plate positioning module for raft foundation concrete construction to solve the above problems. Summary of the Invention

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-13 The present invention provides the following three preferred embodiments: Example 1: A positioning module for a waterstop steel plate in raft concrete construction includes a lower transverse formwork 1, a lower longitudinal formwork 2, an upper transverse formwork 3, an upper longitudinal formwork 4, a transverse waterstop steel plate 5, and a longitudinal waterstop steel plate 6. The lower transverse formwork 1 is positioned transversely in the area to be poured, the lower longitudinal formwork 2 is positioned longitudinally in the area to be poured, the upper transverse formwork 3 is positioned directly above the lower transverse formwork 1, and the upper longitudinal formwork 4 is positioned directly above the lower longitudinal formwork 2. The upper and lower sides of the transverse waterstop steel plate 5 are positioned by the upper transverse formwork 3 and the lower transverse formwork 1, respectively. The upper and lower sides of the longitudinal waterstop steel plate 6 are positioned by the upper longitudinal formwork 6. 4. Positioning of the lower longitudinal template 2: A positioning module for the waterstop steel plate in raft concrete construction is set up, consisting of the lower transverse template 1, lower longitudinal template 2, upper transverse template 3, upper longitudinal template 4, transverse waterstop steel plate 5, and longitudinal waterstop steel plate 6. The installation of the lower transverse template 1, lower longitudinal template 2, upper transverse template 3, and upper longitudinal template 4 simultaneously positions and fixes the transverse waterstop steel plate 5 and longitudinal waterstop steel plate 6, thus avoiding the need for independent installation structures to position the transverse waterstop steel plate 5 and longitudinal waterstop steel plate 6. This optimizes the positioning method of the transverse waterstop steel plate 5 and longitudinal waterstop steel plate 6, thereby effectively improving the overall construction efficiency of the project.
[0019] Within the area encompassing the lower horizontal formwork 1, lower vertical formwork 2, upper horizontal formwork 3, and upper vertical formwork 4, lower reinforcing bar modules 7, upper reinforcing bar modules 8, and vertical reinforcing bars 9 are arranged. Both the lower reinforcing bar modules 7 and upper reinforcing bar modules 8 are composed of horizontal reinforcing bars 10 and vertical reinforcing bars 11, which are arranged in a grid pattern and are connected by binding wire. The lower end of the vertical reinforcing bar 9 is buried below the ground, and the intersection of the vertical reinforcing bar 9 with the horizontal reinforcing bars 10 and the vertical reinforcing bars 11 is secured by binding wire.
[0020] Example 2: Based on Example 1, the lower transverse template 1 and the upper transverse template 3 are positioned by means of a transverse reinforcement structure 12. The lower end of the transverse reinforcement structure 12 is welded and positioned on the transverse reinforcement 10 on the lower reinforcement module 7. The lower longitudinal template 2 and the upper longitudinal template 4 are positioned by means of a longitudinal reinforcement structure 13. The lower end of the longitudinal reinforcement structure 13 is welded and positioned on the longitudinal reinforcement 11 on the lower reinforcement module 7. Both the transverse reinforcement structure 12 and the longitudinal reinforcement structure 13 are composed of a first-level reinforcement member 21, a second-level reinforcement member 22, a third-level reinforcement member 23 and a fourth-level reinforcement member 24. The first-level reinforcement member 21, the second-level reinforcement member 22, the third-level reinforcement member 23 and the fourth-level reinforcement member 24 are all steel bars, and the first-level reinforcement member 21, the second-level reinforcement member 22, the third-level reinforcement member 23 and the fourth-level reinforcement member 24 are all arranged in a Z-shape. The upper end of the first-level reinforcement member 21, the second-level reinforcement member 22, the third-level reinforcement member 23 and the fourth-level reinforcement member 24 are all integrally formed with threaded rods 25.
[0021] The threaded rods 25 of the primary reinforcement members 21 and 22 on the transverse reinforcement structure 12 pass through the mounting holes on the lower transverse template 1. The threaded rods 25 of the tertiary reinforcement members 23 and 24 on the transverse reinforcement structure 12 pass through the mounting holes on the upper transverse template 3. The threaded rods 25 of the primary reinforcement members 21 and 22 on the longitudinal reinforcement structure 13 pass through the mounting holes on the lower longitudinal template 2. The threaded rods 25 of the tertiary reinforcement members 23 and 24 on the longitudinal reinforcement structure 13... Through the mounting holes on the upper longitudinal template 4, horizontal reinforcing beams 14 are fixedly installed on the outer sides of the lower transverse template 1 and the upper transverse template 3 with iron nails. Vertical reinforcing beams 15 are fixedly installed on the outer sides of the lower longitudinal template 2 and the upper longitudinal template 4 with iron nails. The horizontal reinforcing beams 14 on the outer sides of the lower transverse template 1 and the upper transverse template 3 are all supported by the first vertical beam 16. The vertical reinforcing beams 15 on the outer sides of the lower longitudinal template 2 and the upper longitudinal template 4 are all supported by the second vertical beam 17.
[0022] The first vertical beam 16 is a pair of wooden beams, with the two beams of the same pair located on both sides of the threaded rod 25. The threaded rod 25 is fitted with a positioning piece 26, which is set in a semi-U shape. The two sides of the positioning piece 26 are respectively locked onto the wooden beams on both sides. The positioning piece 26 is positioned on the threaded rod 25 by a positioning nut 27. The root of the threaded rod 25 is integrally formed with a retaining ring 28, which abuts against the inner side of the corresponding template. The lower horizontal template 1 and the upper horizontal template 3 are assisted in positioning by the transverse reinforcement structure 12, and the lower longitudinal template 2 and the upper longitudinal template 4 are assisted in positioning by the longitudinal reinforcement structure 13. This effectively improves the stability of the lower horizontal template 1, the lower longitudinal template 2, the upper horizontal template 3, and the upper longitudinal template 4, thereby ensuring the installation stability of the transverse waterstop steel plate 5 and the longitudinal waterstop steel plate 6.
[0023] Example 3: Based on Example 2, a lower reinforcing angle steel 18 is provided at the corner where the lower horizontal template 1 and the lower vertical template 2 meet, and an upper reinforcing angle steel 19 is provided at the corner where the upper horizontal template 3 and the upper vertical template 4 meet. The lower reinforcing angle steel 18 and the upper reinforcing angle steel 19 are both positioned on the corresponding horizontal reinforcing beam 14 and vertical reinforcing beam 15 through connectors 20. The setting of the lower reinforcing angle steel 18 and the upper reinforcing angle steel 19 can ensure the connection strength at the junction of the horizontal template and the vertical template, and can prevent grout leakage at the junction.
[0024] The upper side of the upper horizontal template 3 and the upper vertical template 4 are provided with a rebar placement groove 32. The ends of the horizontal rebar 10 and the vertical rebar 11 on the upper rebar module 8 are placed in the rebar placement groove 32. A sealing piece 33 is provided at the position of the rebar placement groove 32. A U-shaped groove 34 is provided on the lower side of the sealing piece 33. The U-shaped groove 34 matches the size of the horizontal rebar 10 and the vertical rebar 11.
[0025] The ends of both the transverse and longitudinal water-stop steel plates 5 and 6 are set at a 45-degree angle, and the junctions of the transverse and longitudinal water-stop steel plates 5 and 6 are welded together. Blocks 29 are fixedly welded to the upper and lower sides of both the transverse and longitudinal water-stop steel plates 5 and 6. During actual installation, the blocks 29 abut against the inner sides of the corresponding templates. Both the transverse and longitudinal water-stop steel plates 5 and 6 have integrally formed outer water-stop protrusions 30 and inner water-stop protrusions 31 on their upper and lower sides. Both the outer and inner water-stop protrusions 30 and 31 are strip-shaped protrusions. During actual installation, the inner water-stop protrusion 31 and the outer water-stop protrusion 30 of the transverse water-stop steel plate 5 and the longitudinal water-stop steel plate 6 are located on the inner and outer sides of the template, respectively. By fixing and welding the stop blocks 29 on the upper and lower sides of the transverse water-stop steel plate 5 and the longitudinal water-stop steel plate 6, the stop blocks 29 and the inner side of the template play a supporting role, thereby limiting the position of the transverse water-stop steel plate 5 and the longitudinal water-stop steel plate 6. This prevents the mechanical vibration of the concrete vibrator during the pouring process from causing the transverse water-stop steel plate 5 and the longitudinal water-stop steel plate 6 to shift in position, thereby further ensuring the actual water-stopping effect of the transverse water-stop steel plate 5 and the longitudinal water-stop steel plate 6.
