Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and in particular to a wall panel supporting device. Background Art

[0002] The traditional construction industry is a labor-intensive industry. It adopts the construction site pouring operation mode, highly concentrates construction personnel, construction materials and construction machinery and equipment, mixes, transports and pours raw materials such as cement and sand and gravel on site. The entire construction process has low technological content, low production efficiency, high resource consumption and serious environmental pollution, which runs counter to the green building concepts such as energy conservation, emission reduction, low carbon and environmental protection. Prefabricated buildings are an important direction for the transformation and upgrading of green buildings. They introduce component-based and modular construction concepts, and use the processing and prefabrication of building components and the assembly of finished components to reduce air pollution, water pollution, noise pollution and soil pollution caused by construction site pouring operations.

[0003] Prefabricated buildings are typical representatives of the industrialization of the construction industry. They use on-site assembly to assemble prefabricated components that have been processed and formed and transported to the construction site to complete the construction process of prefabricated buildings. Since this model does not require large-scale construction operations at the construction site, it does not require a lot of manpower and material resources, and avoids dust and cross-contamination at the construction site. It has a promoting effect on local natural environment protection, construction energy consumption reduction, and construction cost reduction. Prefabricated wall panels are an important component of prefabricated buildings. During on-site installation, how to conveniently and efficiently fix the prefabricated wall panels and ensure that there is no slight shaking after the wall panels are fixed is a major problem that many people in the industry are currently working hard to solve.

[0004] Chinese Patent No.: ZL202122349473.0 discloses an assembled wall fixing support device, including a tripod for limiting support, a retractable support rod is provided above the tripod, two support rods are provided, and the two support rods respectively fix the upper and lower parts of the prefabricated wall; the two ends of the two support rods are respectively hinged to the prefabricated wall and the floor slab through connecting parts, and the connecting parts include a sleeve, an embedded plate and a connecting plate. The sleeve is arranged inside the prefabricated wall and the floor slab, and an internal thread is provided inside the sleeve, and the sleeve is bolted to the connecting plate. The wall fixing support device has a simple structure. The position of the prefabricated wall is fixed by a tripod, and the verticality of the wall is ensured together with a level tube. Pre-buried positioning holes are provided in the prefabricated wall and the floor slab, so no bulge is caused in the floor slab. However, since the prefabricated wall and the floor slab need to be hinged by connecting parts, holes need to be punched in the prefabricated wall before installation, which causes damage to the wall. After the installation is completed, the punched positions need to be filled and repaired, which prolongs the assembly time. Secondly, the effect of supporting and fixing only one side of the wall is limited. When the wall tilts backward, the tension on the floor slab increases and may damage the floor slab. Finally, the scope of application of the support device is limited. The higher the height of the wall, the longer the first support rod used. When fixing two wall panels at right angles, the two first support rods may interfere with each other, and the force exerted on the oblique support mechanisms such as the first support rod and the second support rod is also greater, and the wall is prone to shaking or tipping.

[0060] Reference Figure 8 and Fig. 9 As shown, in this embodiment, an elastic member slide groove 231 and an elastic member clamping groove 232 are provided on the upper part of the lifting block 23; a contraction portion 211 is provided at the top and the bottom of the serrated through groove 21, and the contraction portion 211 at the top of the serrated through groove 21 is convenient for changing the rotation direction after the lifting block 23 moves to the top of the serrated through groove 21 under the action of the contraction portion 211, so that the end of the elastic member 22 can be clamped in the elastic member clamping groove 232, thereby locking the lifting block 23; the contraction portion 211 at the bottom of the serrated through groove 21 is convenient for changing the rotation direction again under the action of the contraction portion 211 after the lifting block 23 moves to the bottom of the serrated through groove 21, so that the elastic member 22 clamped in the elastic member clamping groove 232 is separated from the elastic member clamping groove 232 and returns to the elastic member slide groove 231, and due to the existence of the elastic member slide groove 231, the elastic member 22 does not affect the small-range rotation of the lifting block 23.

[0061] Reference Figure 1As shown, in this embodiment, two longitudinal limit plates 61 with L-shaped cross-sections are provided on the top of the fixed seat 6, and through holes are provided on the longitudinal limit plates 61 to be rotatably connected to the screw rod 41 and the second adjustment sleeve 52. The vertical sides of the two longitudinal limit plates 61 are close to each other, and the horizontal sides of the two longitudinal limit plates 61 are movably connected to the upper surface of the fixed seat 6 by screws 62. The two longitudinal limit plates 61 can limit the movement freedom of the screw rod 41 and the second adjustment sleeve 52 from both sides of the screw rod 41 and the second adjustment sleeve 52, so that the screw rod 41 and the second adjustment sleeve 52 can only rotate in the through holes on the longitudinal limit plates 61 respectively; the screws 62 facilitate the longitudinal limit plates 61 to be movably connected to the fixed seat 6, and at the same time, the screws 62 can fix the longitudinal limit plates 61 and the fixed seat 6 to the ground to prevent the fixed seat 6 from being displaced, so that the upper adjustment mechanism 4 and the lower adjustment mechanism 5 respectively provide pulling force on the upper and lower parts of the wall panel to keep the wall panel in a fixed state.

[0062] Example 2

[0063] When using the utility model, after using a lifting and handling machine to lift the wall panel to the installation position, the fixing hooks 11 on the lap frame 1 are placed on both sides of the top of the wall panel, so that the vertical section on the top plate 12 is located on the back of the wall panel, and the horizontal end surface 124 on the top plate 12 is located on the top surface of the wall panel. The end of the lap frame 1 connected to the lifting frame 2 is located on the front of the wall panel, and the top plate 12 is moved along the sliding rod 111 by rotating the first rotating handle 113, and the upper part of the wall panel is clamped by the top plate 12 and the lap frame 1, and the cross bar 3 is installed on the lap frame 1 and the lifting frame 2 respectively. After the lap frame 1 is placed again at the other end of the cross bar 3, the top plate 12 is moved and the wall panel is clamped by the first rotating handle 113, and then the fixing seat 6 is installed according to the on-site conditions to ensure that the fixing seat 6 in the fixing device for fixing the two wall panels at the right angle will not interfere with each other, and then a pair of longitudinal limit plates 61 are used to simultaneously fix After fixing the bottom end of the screw rod 41 at the lower end of the upper adjustment mechanism 4 and the bottom end of the second adjustment sleeve 52 in the lower adjustment mechanism 5, fix the fixing seat 6 to the ground by means of the screw 62, and then respectively install the first adjustment sleeve 42 in the upper adjustment mechanism 4 and the screw rod 41 at the other end and the telescopic rod 51 in the lower adjustment sleeve, drive the first adjustment sleeve 42 to rotate by means of the second rotating handle 421, adjust the distance between the screw rods 41 at both ends of the first adjustment sleeve 42, and thereby adjust the straight-line distance between the top of the wall panel and the fixing seat 6. When the wall panel is perpendicular to the horizontal ground, tighten the positioning bolt 521 so that the bottom of the positioning bolt 521 extends into the positioning groove 511 on the surface of the telescopic rod 51 and abuts against the bottom of the positioning groove 511, thereby keeping the distance between the two ends of the lower adjustment mechanism 5 fixed, thereby keeping the distance between the lower end of the wall panel and the fixing seat 6 fixed, and then the lifting and handling machinery can be evacuated.

[0064] According to the wall panels of different heights, the plug rod 13 can be lifted so that the lifting block 23 at the bottom of the plug rod 13 can be clamped in the sawtooth groove 21 at different heights. When the supporting cross bar 233 at the bottom of the lifting block 23 falls on the sawtooth groove 21, the lifting block 23 supports the plug rod 13 under the action of the second fixing rod 133, thereby supporting the entire bridging frame 1;

[0065] When the position of the lifting block 23 needs to be adjusted, the plug-in rod 13 is moved upward in the lifting frame 2 to the top of the sawtooth slot 21, and the lifting block 23 is rotated under the limit of the contraction part 211 at the top of the sawtooth slot 21, so that the elastic member 22 originally in the elastic member slide groove 231 is clamped into the elastic member clamping groove 232, and the lifting block 23 is fixed to prevent the lifting block 23 from contacting the serrated side of the sawtooth slot 21 after the lifting block 23 is rotated. 2 moves downward to the bottom end of the sawtooth groove 21, and the lifting block 23 rotates again under the limit of the contraction part 211 at the bottom of the sawtooth groove 21, so that the elastic member 22 originally in the elastic member slot 232 returns to the elastic member slide groove 231 again under the action of elastic force, and the plug-in rod 13 continues to move upward in the lifting frame 2, so that the lifting block 23 can be engaged with the sawtooth groove 21 again, so that the sawtooth groove 21 is used to support and fix the bridging frame 1.

[0066] Since the lap frame 1 can support and clamp the front, back and top surfaces of the wall panel, and then support the lower part of the wall panel through the lifting frame 2, the wall panel fixed by the device will not tilt, shake or move after maintaining a vertical state, thereby reducing the pressure of the upper adjustment mechanism 4 and the lower adjustment mechanism 5. It can be suitable for fixing wall panels of different heights and thicknesses without damaging the wall and using adhesive tools, thus saving the assembly time of prefabricated buildings and improving work efficiency. It has wide promotion and application value in the field of prefabricated building technology.
