Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of a construction scaffolding of the present invention, as shown in fig. 1-8, includes a support structure 200 and a i-beam 300.
The I-steel 300 is horizontally arranged and fixed on the horizontal construction plane 100; specifically, the anchoring end of the i-beam 300 is fixed to the construction plane 100 by using a plurality of anchor rings, and the length of the anchoring end of the i-beam 300 is greater than 1.25 times the length of the overhanging end.
The supporting structure 200 is located at the lower side of the overhanging end of the i-steel 300 and is used for being abutted with the building wall surface perpendicular to the construction plane 100, so as to support the i-steel 300; when the i-beam 300 is obliquely arranged relative to the building wall surface, the included angles between the two sides of the i-beam 300 and the building wall surface are respectively acute angles and obtuse angles.
The supporting structure 200 comprises a fixing seat 210, a supporting plate 220 and a supporting rod 230, wherein the fixing seat 210 is positioned at the lower side of the overhanging end of the I-steel 300 and is fixedly connected with the I-steel 300, and the fixing seat 210 is arranged along the length direction of the I-steel 300; the support plate 220 is vertically arranged, one end of the support plate 220 is rotatably mounted at one end, close to a building wall, of the fixing seat 210 around a vertical axis, and when the I-steel 300 is inclined relative to the building wall, the support plate 220 can rotate to be abutted with the building wall. The fixing base 210 is provided with a supporting groove 211, one side groove wall of the supporting groove 211 far away from the building wall is an inclined surface, the inclined surface is obliquely arranged relative to the building wall, and one end of the inclined surface close to the building wall is positioned on the same side with one end hinged with the supporting plate 220 and the fixing base 210 and is positioned on one side close to an acute angle defined by the I-steel 300 and the building wall. The support rods 230 are multiple and have different lengths, two ends of the support rods 230 are respectively a first end and a second end, the first ends of the support rods 230 are slidably arranged on the inclined plane, and the second ends of the support rods 230 are hinged with the support plates 220; the support rod 230 drives the support rod 230 to slide along the inclined plane and draw close to one end of the inclined plane, which is close to the building wall surface, in the process that the support plate 220 rotates to be attached to the building wall surface, so that the supporting force of the support plate 220 on one side, which is close to the acute angle, of the I-steel 300 is increased. Specifically, after the support rod 230 moves along with the support plate 220, the support rod 230 needs to be fixed, so that the support rod 230 has a supporting effect on the support plate 220, and the support rod 230 and the fixing seat 210 can be fixed by welding or fastening with bolts. When the i-steel 300 is vertically arranged relative to the building wall, the support plate 220 does not rotate relative to the fixing seat 210, and the plurality of support rods 230 are distributed in parallel and push the support plate 220 along the direction perpendicular to the support plate 220. When the i-beam 300 is obliquely arranged relative to the building wall, downward stress can be generated by the overhanging end of the i-beam 300 under the action of the gravity of the structure on the overhanging end, and the stress is transmitted to the building wall through the support structure 200, so that the damage of the i-beam 300 to the edge of the construction plane 100 is avoided. And because the i-steel 300 at the corner of the construction plane 100 is obliquely arranged compared with the building wall, when the overhanging end of the i-steel 300 generates downward stress, the acting force on the building wall near the acute angle side is larger than the acting force on the building wall near the obtuse angle side, and the supporting effect of the supporting rod 230 on the supporting plate 220 near the acute angle side is increased by making the supporting rod 230 close to the acute angle side, so that the component force perpendicular to the supporting plate 220 is larger as the supporting rod 230 is closer to the acute angle side.
In this embodiment, the supporting plate 220 is a telescopic plate structure, and includes a first plate body 221 and a second plate body 222, where the first plate body 221 and the second plate body 222 are attached to each other and slidingly connected along a horizontal direction, and one end of the first plate body 221 is hinged to the fixing seat 210 around a vertical axis. The fixing base 210 is further provided with a sliding plate 212, the sliding plate 212 is slidably mounted on the fixing base 210 and hinged to one end of the second plate 222, and the fixing base 210 limits the sliding plate 212 to move along a sliding direction perpendicular to the sliding plate 212. The other end of the support bar 230 is hinged with the second plate 222 around a vertical axis; the support plate 220 rotates to be attached to the building wall, and the sliding plate 212 is driven to slide along the fixing base 210 until the support plate 220 is attached to the building wall, and the position of the support plate 220 is fixed by fixing the sliding plate 212 to the fixing base 210. Specifically, the fixing base 210 is provided with a bolt hole, and a first plate with a proper length is selected to be fixed with the fixing base 210 through the bolt hole, so that the first plate can prevent the sliding plate 212 from sliding in a direction away from the building wall surface, and then the supporting plate 220 is kept attached to the building wall surface through the sliding plate 212.
In the present embodiment, the fixing base 210 is further provided with a chute 213; the supporting structure 200 further includes a pre-positioning plate 240, where the pre-positioning plate 240 is slidably mounted on the chute 213 and is configured to abut against the i-steel 300, so as to determine the mounting position of the i-steel 300 relative to the fixing base 210. The pre-positioning plate 240 is hinged to the second plate 222 around the vertical axis, the second plate 222 drives the pre-positioning plate 240 to move in the process of rotating the support plate 220 to be attached to the building wall, and the chute 213 limits the pre-positioning plate 240 to move along the direction perpendicular to the length direction of the I-steel 300 under the driving of the second plate 222, so that the mounting position of the I-steel 300 on the fixing seat 210 moves towards the direction close to the obtuse angle. In the initial state, the pre-positioning plate 240 is located at one end of the chute 213, so that the i-steel 300 is located at the center of the fixing base 210 when the i-steel 300 abuts against the side surface of the pre-positioning plate 240. When the i-beam 300 is obliquely arranged relative to the building wall, the acting force of the overhanging end of the i-beam 300 on the building wall near the acute angle side is larger than the acting force of the building wall near the obtuse angle side when downward stress is generated on the overhanging end of the i-beam 300, and the acting force of the overhanging end of the i-beam 300 on the building wall near the acute angle side is further reduced by enabling the mounting position of the i-beam 300 relative to the fixing seat 210 to move towards the direction near the obtuse angle. The concrete shape of the chute 213 is an arc-shaped slot, which can be obtained by three-dimensional modeling or actual operation scribing, so as to ensure that the pre-positioning plate 240 can only move along the length direction perpendicular to the i-steel 300, and the larger the inclination angle of the i-steel 300 relative to the building wall surface is, the larger the rotation angle of the support plate 220 is, the larger the displacement of the pre-positioning plate 240 is, and the closer the i-steel 300 is to the obtuse angle direction when the i-steel 300 is attached to the pre-positioning plate 240, so that the offset of the i-steel 300 relative to the fixing seat 210 is matched with the inclination degree of the i-steel 300 relative to the building wall surface. Specifically, the fixing base 210 is provided with a long hole to adapt to different mounting positions of the i-steel 300 relative to the fixing base 210. In order to increase the fixing effect of the i-beam 300 and the fixing base 210, bolt holes are formed in the fixing base 210 and two sides of the i-beam 300, two second plates with proper lengths are selected to be fixed with the fixing base 210 through the bolt holes, so that the second plates can prevent the i-beam 300 from moving on the fixing base 210 along the direction perpendicular to the length direction of the i-beam 300. Wherein, the first plate and the second plate are all plate-shaped structures common in the prior art, and the first plate and the second plate are all provided with mounting holes adapted to the bolt holes on the fixing base 210, and the sliding plate 212 and the i-steel 300 are fixed relative to the fixing base 210 by selecting the first plate and the second plate with different sizes.
In this embodiment, the first end of each support rod 230 is hinged with a sliding block 231, and a sliding rail disposed along the inclined surface is disposed on the inclined surface of the support groove 211, where the sliding block 231 is slidably mounted.
In this embodiment, after the supporting plate 220 is attached to the wall surface of the building, the supporting rod 230 is prevented from moving along the sliding rail by placing a wedge of a preset length in the sliding rail.
In some other embodiments, the support rod 230 is provided with a push rod assembly, the push rod assembly comprises a middle rod and two push rods, the middle rod is rotatably installed on the support rod 230 and is parallel to the support rod 230, the two push rods are respectively positioned at two ends of the middle rod, and the two push rods are respectively in threaded connection with the middle rod and have opposite screw threads; by rotating the intermediate rod, the two pushing rods are far away from each other, and then the two pushing rods respectively push against the supporting plate 220 and the sliding rail, so as to prevent the supporting rod 230 from moving along the sliding rail.
In some other embodiments, the support bar 230 may be secured using both a wedge and a ram assembly.
In this embodiment, the supporting structure 200 and the i-steel 300 form one steel frame unit, and a plurality of steel frame units are installed on the same construction plane 100. And when the i-beam 300 is inclined in different directions with respect to the wall surface of the building, the support structure 200 in which the support plate 220 rotates in different directions is required to be selected.
In this embodiment, the steel frame units between two adjacent layers of construction planes 100 are connected by two sections of steel cables, and the two sections of steel cables are connected by a turnbuckle, specifically, one end of each of the two sections of steel cables is connected to one end of the fixing base 210 located above, which is close to the building wall, and the other end is connected to one end of the fixing base 210 located below, which is far away from the building wall. The steel cable is tensioned by rotating the basket bolts, so that the stability of the steel frame unit positioned below is further improved.
According to the building scaffold, the support structure 200 for rotating the support plate 220 in different directions is selected according to the inclined direction of the I-steel 300 relative to the building wall surface, so that the support plate 220 can be attached to the building wall surface after rotating, and the I-steel 300 can be kept in line with the fixing seat 210. When in use, the support plate 220 corresponding to the support structure 200 can be rotated according to the installation angle of the I-steel 300 relative to the building wall surface, and the I-steel 300 is fixedly installed with the fixing seat 210 and then the I-steel 300 is installed on the construction plane 100; after the i-beam 300 is fixedly installed on the construction plane 100, the fixing base 210 may be connected to the i-beam 300, and the installation position of the i-beam 300 with respect to the fixing base 210 may be adjusted by moving the fixing base 210 with respect to the i-beam 300.
When the latter method is adopted, after the I-steel 300 is fixedly arranged on the construction plane 100, the I-steel 300 is connected with the long hole on the fixed seat 210 by the bolt, the fixed seat 210 is pre-connected with the I-steel 300, the I-steel 300 is abutted with the side surface of the pre-positioning plate 240 on the fixed seat 210, and one end of the supporting plate 220 hinged with the fixed seat 210 is abutted with the building wall surface. And then the support plate 220 is rotated to be attached to the wall surface of the building, the second plate body 222 drives the pre-positioning plate 240 to move in the rotation process of the support plate 220, so that the fixing seat 210 moves relative to the I-steel 300 along the direction perpendicular to the I-steel 300, and meanwhile, the support rods 230 move towards one side close to the acute angle along the sliding rail on the inclined surface. After the supporting plate 220 is attached to the building wall, a first plate with a proper length is selected to be fixed with the fixing seat 210, so that the position of the supporting plate 220 is fixed, and a second plate with a proper length is selected to be fixed with the fixing seat 210, so that the relative positions of the fixing seat 210 and the I-steel 300 are fixed; the support rod 230 is fixed by using wedge blocks and/or a jacking component, so that the support force of the fixing base 210 on the side close to the acute angle is increased.
After the steel frame units on the multi-layer construction plane 100 are installed, steel cables are connected between two adjacent layers of steel frame units for reinforcement, and other structures such as upright rods, cross rods, protective nets and the like can be continuously installed at the overhanging ends of the I-beams.
