Description
Technical Field
The invention relates to a fastening device for a scaffold for building construction.
Background
Scaffolding (scaffold) refers to the various supports erected on a construction site for workers to handle and address vertical and horizontal transport. The general term of the building industry refers to the places which cannot be directly constructed on the building site and are used for exterior wall, interior decoration or high floor height. Mainly for constructors to live up and down or for peripheral safety net enclosure, overhead installation components and the like, the scaffold is said to be made of bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolds as templates, and in addition, the scaffold is widely used in advertising, municipal administration, traffic roads and bridges, mines and other departments.
In the high-rise building construction, what use steel pipe scaffold frame as the main, but steel pipe scaffold frame is in putting up the completion back, only relies on the bottom to squeeze into the ground and realize fixing, and only adopts steel pipe cooperation expansion bolts to fix between it and the building subject, and when outside wind-force is great, the scaffold frame can appear rocking, leads to expansion bolts to be pulled out the wall, leads to fixed inefficacy, consequently, the accident that the scaffold frame collapsed can often appear.
Based on the above problem, we have designed a can with the building between the wall body fix, give scaffold frame elastic support simultaneously, effective energy-absorbing avoids the construction scaffold frame fastener that the scaffold frame collapses.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a fastening device of a scaffold for building construction, which can be fixed with a wall of a building, can provide elastic support for the scaffold, can effectively absorb energy and can avoid the collapse of the scaffold.
In order to solve the problems, the invention adopts the following technical scheme:
a fastening device for a building construction scaffold comprises two steel plates which are arranged in front of and behind, a clamping opening is formed between the two steel plates and corresponds to a wall body of a building, a bolt is assembled between the two steel plates, a hole penetrating through the bolt is drilled in the steel plates, the hole diameter of the hole is larger than the diameter of the bolt, the bolt tightens the clamping opening, a transverse strip-shaped groove is arranged on the surface of each steel plate, a plurality of strip-shaped grooves are arranged on the left side and the right side of each steel plate, a steel rod penetrates through the strip-shaped grooves and penetrates through the two steel plates, two sliding sleeves are sleeved on the steel rod and are respectively positioned on the outer sides of the two steel plates, a plurality of screw holes are processed in the outer wall of each sliding sleeve, screws are matched through the screw holes, a plurality of through holes are arranged on the end faces of the sliding sleeves in an annular manner, and sliding rods are assembled through the through holes, one end of the sliding rod is machined to form a limiting end part, the diameter of the end part is larger than that of the through hole, the end part faces the steel plate, the other end of the sliding rod is provided with a first sliding sleeve for limiting, a first screw is arranged between the first sliding sleeve and the sliding rod, a spring is sleeved on the sliding rod and props against the end part and the sliding sleeve, under the action force of the spring, the end part contacts with the steel plate, the spring is compressed at the moment, the end of the steel rod, which is positioned outdoors, is provided with a movable pipe, the rear end of the movable pipe is provided with a notch, the steel rod is arranged in the notch, a bolt is matched between the steel rod and the movable pipe, the outer wall of the movable pipe is provided with a through groove, the through groove radially penetrates through the movable pipe, when the scaffold is installed, the transverse pipe of the scaffold penetrates through the through groove, the end, which is far away from the steel rod, is closed, and a long screw is screwed into one end of the movable pipe, which is far away from the steel rod, and the long screw is screwed into the end and then props against the transverse pipe of the scaffold.
Preferably, the top processing of steel sheet has a notch, two between the steel sheet, it is equipped with a backing plate to be located notch department, the preceding, the trailing flank of backing plate all processes there is the slope, is provided with in the bottom of backing plate and corresponds the slot of steel sheet, and the steel sheet is inserted in this slot position department.
Preferably, the top of backing plate is provided with a recess, has welded a cross axle in the recess, is equipped with a apron that can overturn and open through this cross axle, and the bottom of apron is provided with the ear, the cross axle assembly is in this ear, and the bottom of ear has through the open slot of cross axle, the groove width of open slot slightly is less than the diameter of cross axle the tank bottom welding of recess has the reference column more than, has first spring through this reference column cooperation, the upper end of first spring is used in the bottom of apron under the supporting role of first spring, the apron upset is opened, and the apron highly is higher than the height of the other end towards indoor that one end this moment the welding has the foot lever on the face of apron.
The design purpose of backing plate is mainly to the construction, during the construction, can transport building materials with the help of elevator, building materials mainly rely on the tip lorry to transport, when in operation, pulling tip lorry is indoor, the elevator can continue to move, because the material weight of pulling is great, consequently, can often take place the tip lorry and take place the swift current car, lead to the tip lorry to fall into in the elevator shaft, there is the potential safety hazard, and through setting up the backing plate, when the wheel of tip lorry was pulled the backing plate, the apron is bounce-back under the effort of spring, it is spacing to the wheel of tip lorry, effectively avoid the swift current car phenomenon.
The invention has the beneficial effects that:
1) the front steel plate and the rear steel plate are fastened with the wall, so that the assembly between the wall and the front steel plate and the wall is firmer and more reliable compared with the fixing mode of the traditional expansion bolt, and the connection failure is avoided;
2) the form that two sliding sleeves are matched with a steel rod is adopted, a plurality of sliding rods are arranged on each sliding sleeve and are elastically supported through springs, when an outdoor scaffold shakes, the steel rods are pulled, the steel rods can transversely move along the strip-shaped grooves and can also longitudinally move along the strip-shaped grooves, the position of each sliding rod can independently move, when the sliding rods move, the springs expand or compress, buffering energy absorption in corresponding directions can be conveniently carried out when the scaffold moves, and collapse caused by large-amplitude swing of the scaffold is effectively avoided;
3) when the scaffold swings transversely, the steel rod and the movable pipe can rotate relatively along the bolt to adapt to small-amplitude swinging of the scaffold, and in actual operation, the fact that the fixed scaffold which is too rigid can cause instant collapse of the scaffold when the fixed scaffold reaches a critical point of fixed strength is found out, so that the movable pipe is designed to adapt to transverse swinging of the scaffold;
4) this product can play fore-and-aft auxiliary stay effect, violently be connected between the pipe through movable tube and scaffold, can play the effect to the support of scaffold, movable tube cooperation steel pole, make the movable tube can only carry out the rotation of horizontal direction along the bolt, and can't realize fore-and-aft removal, consequently can realize the fore-and-aft support of scaffold with the help of the cooperation of movable tube and steel pole, rethread steel sheet and building between fixed, the firmness of scaffold is increased with the help of the intensity of building.
