Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a prefabricated wall panel. Background Technology

[0002] Precast wall panels are steel-reinforced concrete slab structural components prefabricated in a prefabrication plant. Because they are pre-made, they are suitable for assembly and use, resulting in a short construction cycle. They are widely used as exterior walls in daily life. Due to their weight, tower cranes are typically used for hoisting. After aligning with the installation holes, fixing, adjustment, and pouring can be carried out. In practice, the alignment process usually involves pre-reserved reinforcing bars on the ground and installation holes on the bottom of the precast wall panel. The tower crane suspends the precast wall panel to align the pre-reserved reinforcing bars with the installation holes. This is usually achieved by using a mirror... The mirror is placed under the precast wall panel and aligned with the hole using the reflection of the mirror. Because the precast wall panel is large and heavy, it needs to be moved and aligned for a long time. Therefore, the mirror needs to be used frequently when calibrating the hole position, which requires a long hoisting time and is inefficient. In addition, cement needs to be poured between the two precast wall panels to stabilize them. Traditionally, a lot of wooden sticks or blocks are needed to fix them with fasteners. The operation is complicated, the workload of workers is large, and the time is long. Moreover, some fasteners will be filled with cement during use, making them difficult to remove later, which is not conducive to speeding up the construction progress. Summary of the Invention

[0003] This invention provides a prefabricated wall panel to solve the technical problems of low efficiency in calibrating installation holes and complex fixing devices and difficult loading and unloading at the joints of prefabricated wall panels during the pouring process.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] This invention provides a prefabricated wall panel, comprising: a prefabricated wall panel, a ground surface, a bracing assembly, a fixing mechanism, and a grouting mechanism;

[0006] The precast wall panel includes a left precast wall panel and a right precast wall panel, each with several lifting rings at the top. The left and right precast wall panels are spliced ​​together, and a fixing mechanism is provided at the splice. Several reserved steel bars extend from the bottom surface of the precast wall panel, and the reserved steel bars are respectively installed in the mounting holes on the ground. The precast wall panel is placed on several raised blocks at the bottom. The bottom of the precast wall panel has a conformal sealing layer that forms a cavity. The grouting mechanism is set between the precast wall panel and the ground to fill the mounting holes and the cavity with cement. The diagonal bracing assembly is diagonally braced between the precast wall panel and the ground.

[0007] Furthermore, one side of the left precast wall panel is concave, and one side of the right precast wall panel is convex. The concave and convex sides match, and the fitting gap is 10mm~15mm on each side. Several steel bars extend from the convex side of the right precast wall panel.

[0008] Furthermore, the diagonal bracing assembly includes several support seats, several lower supports, and several upper supports;

[0009] Several of the aforementioned support seats are fixedly installed on the inner wall surface and the ground of the precast wall panel. The upper and lower ends of several lower supports are respectively hinged to the near-end support seats on the precast wall panel and the ground, supporting the lower half of the precast wall panel. The upper and lower ends of several upper supports are respectively hinged to the far-end support seats on the precast wall panel and the ground, supporting the upper half of the precast wall panel.

[0010] Furthermore, the grouting mechanism includes several grouting cylinder assemblies and a grouting machine;

[0011] Several of the aforementioned grouting cylinder assemblies are installed at the bottom of the precast wall panel, with one end encapsulated inside the precast wall panel and the other end outside the precast wall panel and inserted into the ground. Cement is filled between the precast wall panel and the ground through a grouting machine.

[0012] Furthermore, the grouting cylinder assembly includes a left grouting cylinder, a main grouting cylinder, a grouting pipe, a connecting pipe, a sealing plug, a grout outlet pipe, and a right grouting cylinder;

[0013] The main grouting cylinder is centrally located, with the left and right grouting cylinders symmetrically distributed on both sides. They are respectively fitted onto the reserved reinforcing bars, and one end of each is encapsulated inside the precast wall panel. The other end is inserted into the respective installation holes when the precast wall panel is installed. The upper end of the main grouting cylinder is provided with a grout outlet pipe, which is placed facing inwards and extends out of the precast wall panel surface. The lower end of the main grouting cylinder is evenly distributed with two connecting pipes and one grouting pipe. The two connecting pipes are respectively connected to the left and right grouting cylinders. The grouting pipe is placed facing inwards and extends out of the encapsulation layer. The sealing plug is used to seal the openings of the grout outlet pipe and the grouting pipe.

[0014] Furthermore, the fixing mechanism includes several fixing plates and several fixing components;

[0015] The fixing plates are respectively attached to both sides of the joint between the left and right precast wall panels, and the fixing components are set up on both sides and fixedly installed on the left and right sides of the left and right precast wall panels, abutting against the fixing plates.

[0016] Furthermore, the fixing assembly includes several tie bolts, several fixing brackets, several threaded sleeves, and several threaded rods;

[0017] The screws are fixedly installed on both sides of the left and right precast wall panels respectively. Several tie bolts are threadedly connected to the screws on both sides and abut against the wall surfaces of the left and right precast wall panels. The screws are fixed by tightening the tie bolts. Several fixing brackets are respectively sleeved on the outer circumferential surface of several threaded sleeves. Several threaded sleeves are threadedly connected to the screws on both sides of the left and right precast wall panels respectively. The length of the fixing bracket at the joint of the fixing bracket and the threaded sleeve is greater than the length of the threaded sleeve.

[0018] Furthermore, the thickness of the encapsulation layer is 5mm to 10mm.

[0019] Furthermore, the shim block is composed of shims of varying thicknesses, with a total thickness of 20mm.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention extends pre-reserved steel bars from the bottom of the precast wall panel and sets installation holes in the ground. During hoisting, the connection between the pre-reserved steel bars and the installation holes can be observed with the naked eye. There is no need to frequently use mirror reflection for calibration. The placement position of the precast wall panel can be quickly adjusted, the hoisting time is short, and the construction efficiency is high.

[0022] 2. The invention features a unique integrated grouting mechanism that minimizes the number of openings in the bottom layer of the precast wall panel. The grouting mechanism connects to various installation holes on the ground, and the grouting equipment pours cement into each installation hole. This results in fast grouting speed, thorough grouting, and reduces the likelihood of hollow areas.

[0023] 3. In this invention, when two precast wall panels are spliced ​​together and need to be poured, the screw in the fixing mechanism is fixedly installed on the precast wall panel. Simply tighten the screw sleeve on the screw, and the fixing frame will be rotated and squeezed by the screw sleeve, and the fixing frame will fasten the fixing plate. After construction, the fixing mechanism will not be solidified by the cement pouring. It is simple to use, install and disassemble, highly efficient, and effectively speeds up the construction progress.

[0024] 4. In this invention, the interface between the two precast wall panels is designed with a "concave-convex" shape, which makes it easier to connect the two precast wall panels. In addition, the cement pouring at the "concave-convex" interface provides better stability and increases the safety performance of the precast wall panels. Attached Figure Description

It should be understood that the reference numerals are also applicable to other identical parts or components.

[0047] As described in the background section, when hoisting existing precast wall panels, the installation holes are usually on the bottom surface of the precast wall panel, making it impossible to visually calibrate the installation. It is necessary to frequently use mirror reflection for calibration, which is slow and inaccurate. In addition, when two precast wall panels are spliced ​​together and cement is poured, the existing fixing devices are complicated to install and remove and take a long time.

[0048] To solve the above problems, refer to Figures 1-2 This application provides a prefabricated wall panel, including a prefabricated wall panel 1, a ground 2, a diagonal bracing assembly 3, a fixing mechanism 4, and a grouting mechanism 6;

[0049] The precast wall panel 1 includes a left precast wall panel 11 and a right precast wall panel 12, and is provided with several lifting rings 5 ​​on the top for tower crane hoisting. The left precast wall panel 11 and the right precast wall panel 12 are spliced ​​together and installed vertically on the ground 2. A fixing mechanism 4 is provided at the splice, which is used to provide support and fixation for the splice of the left precast wall panel 11 and the right precast wall panel 12 by pouring cement at the splice.

[0050] Several precast steel bars 13 protrude from the bottom of the precast wall panel 1, and several corresponding mounting holes 21 are provided on the ground 2. The several precast steel bars 13 are respectively installed in the mounting holes 21 on the ground 2.

[0051] When hoisting the precast wall panel 1, the outwardly protruding reserved steel bars 13 can be directly observed and aligned with the naked eye, making the installation more convenient and speeding up the installation of the precast wall panel 1. At the same time, by using the reserved steel bars 13 to connect with the ground 2, the stability of the connection between the precast wall panel 1 and the ground 2 can be effectively enhanced.

[0052] The precast wall panel 1 is provided with several shims 9, which are composed of several shims of different thicknesses, with a total thickness of 20mm. The shims 9 are used to raise the precast wall panel 1, leaving space underneath while keeping the bottom surface of the precast wall panel 1 level and making the bottom of the precast wall panel 1 more stable. The bottom of the precast wall panel 1 is provided with a conformal sealing layer 7 according to its shape, forming a cavity 8. The thickness of the sealing layer 7 is preferably 5mm~10mm. Cement is poured into the cavity 8 to fix the precast wall panel 1 to the ground.

[0053] In this embodiment, the diagonal bracing assembly 3 is diagonally braced between the precast wall panel 1 and the ground 2, and its two ends are fixedly connected to the precast wall panel 1 and the ground 2 respectively, for shaping the precast wall panel 1 and the ground 2. The diagonal bracing assembly 3 includes several support seats 31, several lower supports 32, and several upper supports 33.

[0054] Several support seats 31 are fixedly installed in pairs on the inner wall surface of the precast wall panel 1 and the ground 2. Several lower supports 32 are hinged at their upper and lower ends to the near-end support seats 31 of the precast wall panel 1 and the ground 2, respectively, and are responsible for supporting the lower half of the wall of the precast wall panel 1. Several upper supports 33 are hinged at their upper and lower ends to the far-end support seats 31 of the precast wall panel 1 and the ground 2, respectively, and are responsible for supporting the upper half of the wall of the precast wall panel 1. Through the diagonal bracing assembly 3, the precast wall panel 1 and the ground 2 can be fixed, while ensuring that the left precast wall panel 11 and the right precast wall panel 12 are on the same plane.

[0055] Reference Figures 2-3 The grouting mechanism 6 is set between the precast wall panel 1 and the ground 2, and is used to fill cement into the mounting hole 21 and the cavity 8. The grouting mechanism 6 includes several grouting cylinder assemblies 61 and a grouting machine (not shown).

[0056] The grouting cylinder assembly 61 is set at the bottom of the precast wall panel 1, with one end enclosed inside the precast wall panel 1 and the other end extending out of the precast wall panel 1 and inserted into the ground 2. It is used by a grouting machine (not shown) to fill cement between the precast wall panel 1 and the ground 2.

[0057] In this embodiment, the grouting cylinder assembly 61 includes a left grouting cylinder 611, a main grouting cylinder 612, a grouting pipe 613, a connecting pipe 614, a sealing plug 615, a grout outlet pipe 616, and a right grouting cylinder 617.

[0058] The grouting cylinder assembly 61 is arranged in groups. In each group, the main grouting cylinder 612 is centrally located, and the left grouting cylinder 611 and the right grouting cylinder 617 are symmetrically distributed on both sides. They are all sleeved on the reserved steel bars 13, and the upper end is encapsulated in the precast wall panel 1. The lower end is inserted into each of the installation holes 21 when the precast wall panel 1 is installed, and is connected to several installation holes 21 respectively. The upper end of the main grouting cylinder 612 is provided with a grout outlet pipe 616. The grout outlet pipe 616 is placed inward of the wall, and the pipe opening extends out of the wall surface of the precast wall panel 1. Two connecting pipes 614 and a grouting pipe 613 are evenly distributed around the lower end of the main grouting cylinder 612. The two connecting pipes 614 are connected to the left grouting cylinder 611 and the right grouting cylinder 617 respectively. The grouting pipe 613 is placed inward of the wall, and the pipe opening extends out of the encapsulation layer 7. The sealing plug 615 is used to seal the pipe openings of the grout outlet pipe 616 and the grouting pipe 613.

[0059] During grouting, the grouting machine (not shown) is connected to the grouting pipe 613, and cement is injected into the main grouting cylinder 612. The cement first fills the mounting hole 21 where the main grouting cylinder 612 is located. After filling, the cement spreads into the cavity 8. At the same time, cement is injected into the left grouting cylinder 611 and the right grouting cylinder 617 through two connecting pipes 614, filling the corresponding mounting holes 21. As grouting continues, the left grouting cylinder 611, the main grouting cylinder 612, and the right grouting cylinder 617 are completely filled. Cement overflows from the outlet pipe 616 and blocks the sealing plug 615. Grouting pipes 616 and 613 are used to sequentially grout the remaining grouting cylinder assemblies 61 until the grouting of several installation holes 21 and cavities 8 is completed. The grouting cylinder assembly 61, by using several connecting pipes 614, can connect several reserved steel bars 13 and installation holes 21 without damaging the precast wall panel 1. While ensuring sufficient grouting, it can effectively reduce the number of holes to be opened at the bottom of the precast wall panel 1, reduce damage to the precast wall panel 1, and reduce the number of times the grouting pipe 613 needs to be replaced for grouting, thus reducing the workload of construction personnel and increasing efficiency.

[0060] Reference Figure 2 , Figures 5-6 In this embodiment, the left precast wall panel 11 is concave on one side and the right precast wall panel 12 is convex on one side. The concave and convex sides match, and the fitting gap is 10mm~15mm on one side. This gap is more suitable for the cement to fill the gap fully during grouting. Several steel bars extend from the convex side of the right precast wall panel 12 and are evenly distributed in the concave side of the left precast wall panel 11.

[0061] During hoisting and assembly, on the one hand, the interplay of concave and convex sections makes it easier to connect and install the left precast wall panel 11 and the right precast wall panel 12, ensuring that the two sides of the left precast wall panel 11 and the right precast wall panel 12 are on the same plane, making installation more convenient and faster. On the other hand, through the gap between the mating sections and the evenly distributed elongated steel bars, grouting effectively enhances the tightness of the left precast wall panel 11 and the right precast wall panel 12, improving construction safety.

[0062] Reference Figure 4 The fixing mechanism 4 includes several fixing plates 41 and several fixing components 42;

[0063] Several fixing plates 41 are respectively attached to both sides of the splice between the left precast wall panel 11 and the right precast wall panel 12, and completely cover the splice area. Several fixing components 42 are set up on both sides and fixedly installed on both sides of the left precast wall panel 11 and the right precast wall panel 12, abutting against the fixing plates 41, and firmly attaching the fixing plates 41 to the wall surface.

[0064] In some embodiments, the fixing component 42 includes a plurality of tie bolts 421, a plurality of fixing brackets 422, a plurality of threaded sleeves 423, and a plurality of threaded rods 424;

[0065] Several screws 424 are respectively fixedly installed in the threaded holes on both sides of the left precast wall panel 11 and the right precast wall panel 12. Several tie bolts 421 are respectively threaded to the screws 424 on both sides and abut against the walls on both sides of the left precast wall panel 11 and the right precast wall panel 12. By tightening the tie bolts 421, the screws 424 are stretched outward to fix the screws 424. Several fixing brackets 422 are respectively sleeved on the outer circumferential surface of several threaded sleeves 423. The length of the fixing bracket 422 at the joint of the fixing bracket 422 and the threaded sleeve 423 is greater than the length of the threaded sleeve 423. Several threaded sleeves 423 are respectively threaded to the screws 424 on both sides of the left precast wall panel 11 and the right precast wall panel 12. By tightening the threaded sleeves 423 to rotate them inward, the fixing brackets 422 sleeved on them can be squeezed inward, thereby pressing the fixing brackets 422 inward against the fixing plate 41.

[0066] During construction, screw rod 424 is tightened onto the left precast wall panel 11 and the right precast wall panel 12 on both sides. The tie bolt 421 is tightened to fix screw rod 424. Fixing plate 41 is placed in the center between the two screw rods 424. Fixing bracket 422 is fitted onto screw sleeve 423. Screw sleeve 423 is tightened. Fixing bracket 422 fixes fixing plate 41, completing the installation of fixing mechanism 4. The operation is simple and does not require additional tools. One person can complete the fixing. Then, concrete is poured from above the joint of left precast wall panel 11 and right precast wall panel 12 until the cement is level with the top surface. After the concrete has solidified, screw sleeve 423 is loosened, fixing bracket 422 is loosened, fixing plate 41 is removed, and tie bolt 421 and screw rod 424 are loosened to complete the disassembly of fixing mechanism 4. Disassembly is simple.

[0067] The specific steps for using this invention are as follows:

[0068] Clean the installation area on the ground 2, confirm whether the positions of the mounting holes 21 and the reserved steel bars 13 are matched, and place several shims 9 in the cleaned installation area;

[0069] The tower crane lifts the left precast wall panel 11 using the lifting ring 5 and hoists it to the installation area above the ground 2. It then slowly lowers the panel to a certain height. The tower crane then holds the left precast wall panel 11 and aligns several reserved steel bars 13 with the installation holes 21. The panel is then slowly installed and placed on several raised blocks 9. At the same time, the grouting pipe 613 is placed stably between the bottom surfaces of the left precast wall panel 11 on the ground 2.

[0070] After the left precast wall panel 11 is placed stably, the diagonal bracing assembly 3 is pre-installed. After confirming that the position and verticality of the side beam wall are correct, the diagonal bracing assembly 3 is connected to the left precast wall panel 11 and the ground 2, and the tower crane hook is removed.

[0071] Using rigid cement mortar, according to the bottom shape of the left precast wall panel 11, apply the sealing layer 7 to expose the grouting pipe 613 opening;

[0072] After the encapsulation layer 7 solidifies, use a grouting machine (not shown) to connect the grouting pipe 613 for grouting until each mounting hole 21, each grouting cylinder assembly 61 and cavity 8 are fully grouted;

[0073] The tower crane lifts the right precast wall panel 12 using the lifting ring 5 and assembles it with the left precast wall panel 11. The mounting holes 21 are aligned and installed. The above steps are repeated.

[0074] After the left precast wall panel 11 and the right precast wall panel 12 are installed securely, the fixing plate 41 is attached to the joint, and the fixing component 42 is used to fix the fixing plate 41. Concrete is poured from above the joint until the concrete has solidified, and then the fixing mechanism 4 is removed.
