Due to the adoption of the technical scheme, the invention has the beneficial effects that:
when the adjustable building construction enclosure provided by the invention is installed, the front side of the enclosure faces the inside of a construction site, and the rear side of the enclosure faces the outside of the construction site.
The adjustable building construction enclosure provided by the invention has four deformation states:
the first state is suitable for being used in construction sites when dust is small, the dust is not required to be specially blocked when the dust is small, the second baffle plate slides downwards on the front side surface of the first baffle plate through the matching of the first sliding groove and the first sliding rail until the lower end of the second baffle plate is supported on the base, and at the moment, the height of the second baffle plate is reduced to the minimum, so that the possibility of overturning of the enclosure provided by the invention can be reduced.
The second state, on the basis of above-mentioned first state, promote the second baffle in the front side of first baffle upwards, first spout upwards slides on first slide rail, and after rising the second baffle to the upper end of first board section surpassed the upper end certain distance of first baffle, support the bracing piece at the downside of first board section, make the bracing piece support the second baffle at fixed height, the clearance between first baffle and the second baffle can be plugged up to the shutoff board. Wind in the construction site blows the dust to enclosing the fender back, the excessive in-process of dust, because the second baffle protrusion in first baffle forward, and the clearance between first baffle of shutoff board shutoff and the second baffle, the shutoff board can block partly dust, and the height of enclosing the fender obtains rising, can further improve the effect of blockking to the dust, can reduce from enclosing the dust that overflows to outside the construction site, after the height that encloses the fender rises, can also make to enclose the fender and look bigger more. This state is suitable for use when the dust is small or slightly large.
Preparing two long bamboo poles, making a Y-shaped fork at the upper end of one of the bamboo poles, on the basis of the second state, using the fork on the bamboo pole with the fork to fork on a second support ring, using the other bamboo pole to stir a second moving rod upwards, driving a second sliding column to move upwards and compress a second compression spring by the second moving rod, moving a second sliding rod upwards along with the second sliding column until the second sliding rod moves upwards to be separated from a third slot, moving the lower end of the second sliding rod upwards to a third sliding rail, pulling the third plate section forwards by the bamboo pole with the fork, enabling the third plate section to slowly rotate forwards by taking the axial lead of the second connecting seat as a rotation center, rotating a second connecting block in the second connecting seat, sliding the third sliding rail in a third sliding groove, and loosening the bamboo pole from the second moving rod in the rotation process of the third plate section, when the second slide bar rotates to just face the fourth slot, under the pressure action of the second compression spring, the second compression spring pushes the second sliding column and the second slide bar towards the direction of the fourth slot, the second slide bar is pressed into the fourth slot, under the matching action of the second slide bar and the fourth slot, the third plate section cannot continue to rotate, at the moment, the third plate section can keep an included angle of 45 degrees with the second plate section, the third plate section can keep an inclination of 45 degrees towards the construction site, after dust in the construction site is blown towards the enclosure by wind, in the process that the dust overflows along the enclosure, as the second baffle projects forwards from the first baffle, and the blocking plate blocks a gap between the first baffle and the second baffle, the blocking plate can block a part of dust, and the third plate section inclines towards the construction site by 45 degrees, the third plate section can play a certain blocking role on the upper end of the enclosure and can guide the dust towards the construction site, the dust overflowing from the enclosure to the outside of the construction site can be reduced, the upper end of the enclosure looks like a shape inclined towards the inside of the construction site, and the enclosure looks more attractive. This state is suitable for use when the dust is small, slightly large or large.
Preparing two long bamboo poles, making a Y-shaped fork at the upper end of one of the bamboo poles, based on the third state, using the fork on the bamboo pole with the fork to fork on the first supporting ring, using the other bamboo pole to stir the first moving rod upwards, the first moving rod drives the first sliding column to move upwards and compress the first compression spring, the first sliding rod moves upwards along with the first sliding column until the first sliding rod moves upwards to be separated from the first slot, the lower end of the first sliding rod moves upwards to the second sliding rail, at this time, the second plate section is pulled forwards through the bamboo pole with the fork, so that the second plate section slowly rotates forwards by taking the axial lead of the first connecting seat as the rotation center, the first connecting block rotates in the first connecting seat, the second sliding rail rotates in the second sliding groove, and in the rotation process of the second plate section, the bamboo pole is loosened from the first moving rod, when the first sliding rod rotates to just face the second slot, under the pressure action of the first compression spring, the first compression spring pushes the first sliding column and the first sliding rod to the direction of the second slot, the first sliding rod is pressed into the second slot, under the matching action of the first sliding rod and the second slot, the second plate section cannot continue to rotate, at the moment, the second plate section can keep an included angle of 45 degrees with the first plate section, the second plate section can keep an inclination of 45 degrees towards the construction site, because the third plate section still has an included angle of 45 degrees with the second plate section in the third state, at the moment, the second plate section is in a horizontal state, after dust in the construction site is blown towards the enclosure, the dust overflows along the enclosure, the second baffle projects forwards from the first baffle, and the plugging plate plugs a gap between the first baffle and the second baffle, the plugging plate can block a part of dust, and the second plate section inclines towards the construction site at 45 degrees, the third plate section is in the horizontality and blocks the upper end at the second plate section, and second plate section and third plate section have further strengthened the effect of blockking to enclosing the fender upper end, and second plate section and third plate section can also lead the dust to the construction site in, can further reduce to spill over to the outer dust of construction site from enclosing the fender, and the second fender has twice buckling, makes the shape of enclosing the fender three-dimensional pleasing to the eye more. This state is suitable for use when the dust is small, slightly large, large or very large.
The enclosure provided by the invention can reduce dust overflowing from the enclosure to the outside of a construction site; the enclosure provided by the invention has four deformations, can be suitable for construction sites with four conditions of small dust, slightly large dust, large dust and very large dust, and has wide application range; the construction project department can select the state of the enclosure by combining the dust size condition and the aesthetic condition of the construction site, and the use is very flexible; when the enclosure state is changed, manual operation is only needed, machine driving is not needed, the design is delicate, and the use is very convenient; the first baffle is detachably connected with the base, so that after one construction site is finished, the enclosure can be detached from the base and transported to the next construction site for use, the enclosure can be reused, and the cost is saved; when the enclosure provided by the invention is transported, the enclosure can be changed to the first state, so that the transportation is convenient.
