Description

Technical Field

[0001] The present invention relates to the technical field of enclosures for construction sites, and in particular to a large enclosure for construction sites that combines publicity and protection functions. Background Art

[0002] Fences are protective measures taken to isolate the construction site from the external environment, making the construction site a relatively closed space. On the one hand, it can ensure the safety of personnel, and on the other hand, it can prevent dust and reduce noise. Construction fences are widely used in the field of construction. Regulations and laws require that construction sites must be equipped with fences. Different types of construction sites and different areas have different requirements for fence heights. Generally, the fence height does not exceed 4m. Angle steel is often used to weld the basic frame, and then the frame is paved with iron sheets and decorative materials. Conventional fencing uses colored steel plates or colored composite panels, which are lightweight, easy to install, quick to use, and reusable, but do not have a promotional function and have a relatively simple shape. They are suitable for the surroundings of conventional construction sites, but for the main roads and prominent locations in the site where quality needs to be improved, the fencing is required to be sturdy and durable, beautiful and elegant, and at the same time, it is necessary to promote the company's corporate culture and site quality and safety. Conventional fencing is relatively light, and when encountering strong winds, the entire baffle on the fencing will be affected by strong winds, causing the fencing to be easily blown down and damaged by the wind. The collapse of the fencing can easily cause safety hazards. Therefore, it is necessary to design a large-scale fencing that can meet the protection and promotional functions and improve the wind resistance of the fencing. Summary of the invention

[0003] In view of the above-mentioned defects and problems, the present invention provides a large-scale enclosure for construction sites which combines publicity and protection functions. The enclosure is particularly suitable for both sides of the main roads at the construction site. It can not only separate and enclose the site roads and the construction site, but also promote the company's corporate culture and the quality and safety of the construction site. The enclosure has beautiful and elegant appearance, is sturdy, durable and not easy to damage.

[0004] The solution adopted by the present invention to solve its technical problems is: a large-scale enclosure for construction sites with publicity and protection functions, including a rectangular fence frame composed of square tube columns and cross frames, and also including movable enclosure panels and enclosure display panels arranged in the fence frame from top to bottom, and fixed pipe seats are installed on the inner sides of two square tube columns, the movable enclosure panels include a hollow shaft tube arranged horizontally in the fence frame, the movable enclosure panels are rotatably sleeved on the fixed pipe seat through the hollow shaft tube below, and the movable enclosure panels are connected to the fence frame through a reset piece; the enclosure display panel includes a plurality of horizontal iron bars arranged longitudinally below the movable enclosure panels The iron plates are connected by connecting rods at odd and even intervals to form an odd iron plate group and an even iron plate group. The upper and lower ends of the odd iron plate group and the even iron plate group are respectively hinged on the fence frame through hinged rods, and the two iron plate groups are respectively connected to the movable enclosure plate through pulling wires. When the movable enclosure plate rotates around the hollow shaft tube, the pulling wire can pull the odd iron plate group or the even iron plate group forward or backward to form a ventilation gap between the two iron plate groups, and when the movable enclosure plate is vertically in the fence frame, the two iron plate groups are in the same plane and form an enclosure display panel. A water spray assembly is also provided on the top of the fence frame.

[0005] Furthermore, the water spray assembly includes a water spray pipe installed on the top of the fence frame front and rear, the water spray pipe is connected to the fixed pipe seat on one side through a water guide pipe, and the fixed pipe seat on the other side is connected to a water inlet pipe, a water flow channel is formed between the fixed pipe seat and the hollow shaft tube, and a valve assembly is provided between the fixed pipe seat and the hollow shaft tube.

[0006] Furthermore, the baffle assembly includes baffles arranged at the end of the hollow shaft tube and in the fixed tube seat, and the two baffles are in contact with each other and have water holes. When the movable baffle plate is vertical, the water holes on the two baffles correspond to each other to achieve water flow. When the movable baffle plate rotates, the water holes on the two baffles are offset to achieve water blocking.

[0007] Furthermore, a movable enclosure frame is formed above the hollow shaft tube by means of vertical bars and horizontal bars, a plurality of horizontal aluminum buckle strips are longitudinally arranged in the movable enclosure frame, and ventilation gaps are left between adjacent aluminum buckle strips.

[0008] Furthermore, the topmost iron strip of the odd-numbered iron plate group is connected to the vertical rod of the movable enclosure plate through a front steel wire, and the topmost iron strip of the even-numbered iron plate group is connected to the vertical rod of the movable enclosure plate through a rear steel wire.

[0009] Furthermore, the reset member is a tension spring that is symmetrically connected to the fence frame, and the outer end of the tension spring is connected to the two ends of the cross bar of the movable enclosure plate. The tension spring allows the movable enclosure plate to be vertically located in the fence frame without being subjected to external force.

[0010] Furthermore, diagonal brace assemblies are symmetrically arranged on both sides of the fence frame, and the diagonal brace assemblies include diagonal brace rods fixed on square tube columns, vertical pipes are fixed to the lower ends of the diagonal brace rods, and ground spikes are vertically slidably sleeved in the vertical pipes.

[0011] The beneficial effects of the present invention are as follows: by arranging movable enclosure panels, enclosure display panels and enclosure frames, the movable enclosure panels are connected to the fence frames through tension springs, and can automatically deflect when subjected to strong winds and reset after the wind disappears, effectively resisting the impact of strong winds on the enclosures, and in conjunction with the pulling wire, the movable enclosure panels can pull the corresponding iron plate groups to move by the pulling wires when deflected, thereby achieving automatic adjustment and change of the shapes of the enclosure display panels under different weather conditions, allowing the enclosures to form ventilation gaps under strong winds, reducing wind resistance, and improving the wind resistance of the enclosures. At the same time, the integrity of the enclosures is maintained when there is no wind or the wind is relatively small, without affecting the isolation and publicity functions of the enclosures. The enclosures can automatically adjust their shapes under strong winds, reducing the risk of enclosure collapse due to excessive wind force, and improving the safety of the construction site. The water spray assembly on the top of the fence frame can spray water to reduce dust in windless or low-wind weather, reducing the impact of dust on the environment. The valve assembly can automatically open or close in conjunction with the state of the movable enclosure plate, and can automatically control the opening and closing of the water spray and dust reduction function according to weather conditions. The design of the valve assembly automatically stops spraying water in strong wind weather, saving water resources and avoiding unnecessary waste of water resources; In summary, the large enclosure of the present invention achieves multiple effects of protection, publicity, wind resistance, dust reduction, resource conservation and safety improvement through ingenious structural design, and is an ideal isolation facility for construction sites.

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0015] See also Figure 1-9 The present invention provides a technical solution for a large enclosure with both publicity and protection functions for a construction site: Example

[0016] according to Figure 1 and Figure 2 As shown, the square tube columns 11 and the cross frames 12 form a rectangular fence frame 1, the distance between the two square tube columns 11 is 4m, and then the two cross frames 12 are welded to the square tube columns 11 at 0.08m and 2.22m from the bottom to form the fence frame 1, and the bottom of the square tube columns 11 is welded with a stainless steel base; a movable enclosure plate 2 is installed on the top of the fence frame 1, and fixed pipe seats 21 are symmetrically installed on the inner sides of the two square tube columns 11. The movable enclosure plate 2 includes a hollow shaft tube 22 arranged horizontally in the fence frame 1, and the movable enclosure plate 2 is rotated and assembled through the hollow shaft tube 22 below. A reset part is installed on the fixed pipe seat 21 and the fence frame 1, and the movable enclosure plate 2 is connected to the fence frame 1 through the reset part. The reset part is a tension spring 8 symmetrically connected to the square tube column 11, and the outer end of the tension spring 8 is connected to the two ends of the cross bar 25 of the movable enclosure plate 2. The tension spring 8 makes the movable enclosure plate 2 vertically in the fence frame 1 without being subjected to external force. When the movable enclosure plate 2 is subjected to external force, such as strong wind, the movable enclosure plate 2 will deviate around the hollow shaft tube 22. When the external force disappears, the tension spring 8 will pull the movable enclosure plate 2 back to its original position to maintain a vertical state.

[0017] The specific structure of the movable enclosure plate 2 is as follows: Figure 3As shown, a rectangular movable enclosure frame is formed above the hollow shaft tube 22 by vertical rods 23 and horizontal rods 25, and 8 horizontal aluminum buckle strips 24 are arranged vertically and fixed in the movable enclosure frame, and a ventilation gap of 2 cm is left between adjacent aluminum buckle strips 24. By leaving ventilation gaps on the movable enclosure plate 2, the wind resistance of the movable enclosure plate 2 can be reduced, and the upper and lower layers use blue aluminum buckle strips 24, and the middle one uses white aluminum buckle strips 24, which improves the aesthetic effect of the fence.

[0018] according to Figure 2 and Figure 4 As shown, a fence display panel 3 is provided below the movable fence panel 2 in the fence frame 1, and the fence display panel 3 includes a plurality of transverse iron strips 31 provided below the movable fence panel 2, and the iron strips 31 are smoothly arranged longitudinally in the fence frame 1 from top to bottom in the order of 1, 2, 3, ... n, and the iron strips 31 are divided into an odd iron plate group 3a and an even iron plate group 3b according to odd and even intervals, the odd iron plate group 3a is composed of the 1st, 2nd, 3rd ... n-1st iron strips 31, and the even iron plate group 3b is composed of the 2nd, 4th, 6th ... nth iron strips 31, and the two sides of adjacent iron strips 31 in each iron plate group are directly connected together by a connecting rod 32. The connecting rod adopts an arc-shaped rod body, and the connecting rods on the two groups of iron plate groups do not interfere with each other. The upper end of the odd-numbered iron plate group 3a and the lower end of the even-numbered iron plate group 3b are respectively hinged on the fence frame 1 through a hinged rod 33, and the two iron plate groups are respectively connected to the movable enclosure plate 2 through a pulling wire 5. The top iron strip plate 31 of the odd-numbered iron plate group 3a is connected to the vertical rod 23 of the movable enclosure plate 2 through a front wire 51, and the top iron strip plate 31 of the even-numbered iron plate group 3b is connected to the vertical rod 23 of the movable enclosure plate 2 through a rear wire 52. When the movable enclosure plate 2 is vertically located in the fence frame 1, the two iron plate groups are in the same plane and form an enclosure display panel 3, such as Figure 6 The state shown in the figure realizes the normal enclosure function; when the movable enclosure plate 2 is blown by strong wind and rotates clockwise around the hollow shaft tube 22, under the cooperation of the hinge rod 33, the front steel wire 51 pulls the odd iron plate group 3a to move forward, so that the odd iron plate group 3a is displaced forward, so that a ventilation gap is generated between the adjacent iron strips 31, such as Figure 7 In the state shown, by forming ventilation gaps on the enclosure display board 3, the impact of wind force on the enclosure display board 3 can be reduced, thereby improving the wind resistance of the enclosure display board 3.

[0019] When using a fence to isolate a construction site, a promotional spray-painted picture or poster can be pasted on the fence display board 3 to realize the promotional function. After the poster is pasted, the worker uses a knife to cut the display board along the gap between the adjacent iron strips 31 so that the poster strip can move with the corresponding iron strip 31, ensuring that when the fence is exposed to strong winds, the odd iron plate group 3a or the even iron plate group 3b of the fence display board 3 can move smoothly, and when the odd iron plate group 3a or the even iron plate group 3b are in the same plane, the poster strips can also be pieced together to form a complete poster without affecting the viewing of pedestrians.

[0020] In specific use, the present invention is a large-scale fence for construction sites with publicity and protection functions. First, a concrete foundation 7 is made at the place where the fence is needed at the construction site according to the spacing of the square tube columns 11, and then the made fence is fixed on the concrete foundation 7 through the base. When the concrete foundation 7 and the base of the square tube column 11 are fixed, expansion screws are used to fix them, and adjacent fences are spliced ​​to form a Fig. 9 The large fence shown is used to isolate the construction site of the building. The fence is normally in Figure 6 In the state shown, the publicity posters are pasted on the enclosure display board 3 for publicity display. When encountering strong wind weather, the enclosure will be impacted by the strong wind. At this time, the movable enclosure board 2 will rotate around the hollow shaft according to the wind direction. When the wind blows from left to right, the movable enclosure board 2 rotates clockwise and deflects. The front steel wire 51 is tightened and exerts a pulling force on the odd iron plate group 3a. Under the cooperation of the hinged rod 33, the odd iron plate group 3a is pulled forward to cause a small displacement, becoming Figure 7 In the state shown, a ventilation gap is formed between the odd-numbered iron plate group 3a and the even-numbered iron plate group 3b. When strong wind blows against the enclosure display panel 3, the wind energy can flow through the ventilation gap, reducing the wind resistance of the enclosure display panel 3 and improving the wind resistance of the enclosure display panel 3. When the wind disappears, under the tension of the tension spring 8, the movable enclosure panel 2 is pulled back to a vertical state, the tension of the pulling wire 5 on the iron plate group disappears, the iron plate group returns to its original position, and the two groups of iron plate groups are spliced ​​to form a plane, and the enclosure and publicity display work continues. Example

[0021] On the basis of the first embodiment, Figure 1 and Figure 2As shown, a water spray assembly 4 is provided on the top of the fence frame 1, and a water spray pipe 41 is horizontally installed on the front and rear sides of the top of the fence frame 1. The water spray pipe 41 is connected to the fixed pipe seat 21 on the left side through a water guide pipe 44, and the fixed pipe seat 21 on the right side is connected with a water inlet pipe 43. A water flow channel is formed between the fixed pipe seat 21 and the hollow shaft tube 22, and a valve assembly 42 is provided between the fixed pipe seat 21 and the hollow shaft tube 22. The water inlet pipe 43 is connected to an external water source. Water flows through the right fixed pipe seat 21, the hollow shaft tube 22, the left fixed pipe seat 21 and enters the water spray pipe 41 through the water guide pipe 44. The water spray pipe 41 sprays water on the front and rear sides of the enclosure to spray water on the front and rear sides of the enclosure to reduce dust.

[0022] according to Figure 8 It can be seen that the valve assembly 42 includes a baffle 421 arranged at the end of the hollow shaft tube 22 and the middle part of the fixed pipe seat 21. The two baffles 421 are in contact with each other, and a water hole 422 is opened on the baffle 421. When the movable baffle plate 2 is vertically located in the fence frame 1, that is, not affected by strong wind, the water holes 422 on the two baffles 421 correspond to each other, and the water flow can smoothly pass through the hollow shaft tube 22 and the fixed pipe seat 21 into the water spray pipe 41 to achieve water spraying and dust reduction. When the movable baffle plate 2 rotates, that is, the enclosure is affected by strong wind, the water holes 422 on the two baffles 421 are offset, and the water flow cannot pass through the water holes 422, thereby blocking the water and stopping the water spraying.

[0023] In specific use, the present invention is a large-scale enclosure for construction sites with publicity and protection functions. When there is no wind or low wind, a large amount of dust will be generated on the construction site. At this time, the water inlet pipe 43 can be connected to an external water source. When the movable enclosure plate 2 is not hit by strong wind, it is vertically located in the fence frame 1. At this time, the water holes 422 of the two baffles 421 correspond exactly, and the valve assembly 42 automatically opens. The water flow will enter the water spray pipe 41 along the fixed pipe seat 21, the hollow shaft pipe 22 and the water guide pipe 44, and be sprayed out from the water spray pipe 41, so as to realize water spraying and dust reduction on the front and rear sides of the enclosure; when encountering strong wind weather, the dust near the enclosure will be blown away by the strong wind, and there is no need to spray water to reduce dust at this time. The movable enclosure plate 2 will be offset and rotated when hit by strong wind, so that the two water holes 422 will be offset synchronously, and the water holes 422 cannot pass water, so as to realize the automatic closing of the valve assembly 42 and save water resources. Example

[0024] On the basis of the first embodiment, Figure 1As shown, diagonal brace assemblies 6 are symmetrically provided on both sides of the fence frame 1. The diagonal brace assemblies 6 include diagonal brace rods 61 fixed to the front and rear sides of two square tube columns 11. The diagonal brace rods 61 are supported by square tubes with a cross-sectional size of 40*40mm and a thickness of 1mm according to the actual situation on site. Each length is 1.5-2.5m. A vertical pipe 62 is fixed to the lower end of the diagonal brace rod 61, and a ground spike 63 is vertically slidably sleeved in the vertical pipe 62. When the enclosure is erected at the construction site, the ground spike 63 is driven into the ground by hammering downward, and the enclosure is assisted by the diagonal brace assembly 6 to prevent the enclosure from being blown down in windy weather, thereby improving the stability of the enclosure.
