Wind resistant fence structure

Abstract

The application discloses an anti-wind fence structure, which comprises a frame body and a baffle assembly. First sliding grooves are formed in the inner sides of the bottom and top frame edges of the frame body. The baffle assembly comprises a wind cavity plate body and a buffer plate assembly. The wind cavity plate body is fixed in the frame body and is internally provided with a wind guide cavity. The wind guide cavity is connected with an air outlet channel and an air inlet channel. The air outlet channel penetrates through the top of the frame body, and the air inlet channel is formed in the other side surface of the wind cavity plate body. The buffer plate assembly is slidably embedded in the frame body and comprises a buffer plate, a sliding part and a sliding block. One side surface of the buffer plate is in sliding contact with the side surface of the wind cavity plate body provided with the air inlet channel, and the other side surface is in sliding contact with the frame edge of the frame body. The buffer plate guides the air flow into the wind guide cavity, buffers the air flow and then guides the air flow out of the frame body through the air outlet channel in the top of the frame body. The anti-wind fence structure not only has strong buffering capacity, but also guides the wind and sand to the top of the frame body, so that the wind and sand are far away from the ground of the construction site, thereby avoiding the situation that the wind and sand directly pass through the fence and adhere to the ground of the construction site to sweep the dust on the ground.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a wind-resistant enclosure structure. Background Technology

[0002] Installing fencing at construction sites serves a preventative function, improving site safety. Furthermore, construction sites generate significant amounts of waste and dust; fencing reduces dust dispersion and minimizes environmental pollution. Additionally, fencing facilitates subsequent cleaning and maintenance.

[0003] However, existing construction site fences, which are made of metal plates for easy installation and dismantling, have limited wind resistance and are easily blown down by strong winds. This not only makes subsequent repairs difficult, but also risks injuring pedestrians. Therefore, it is necessary to enhance the wind resistance of the fences to make them suitable for windy weather and ensure that they will not be easily blown down in strong winds. Summary of the Invention

[0004] The purpose of this invention is to provide a wind-resistant enclosure structure that not only has strong wind resistance but also blocks and guides the wind, keeping sand away from the ground of the construction site, thereby preventing sand from directly passing through the enclosure and sticking to the ground of the construction site to sweep up dust.

[0005] The technical solution of this invention is:

[0006] A wind-resistant enclosure structure, mounted on a support structure fixed to the ground, includes: a frame, with a bottom frame edge on one side connected to the support structure, and first sliding grooves extending along the width direction on the inner sides of the bottom and top frame edges; a baffle assembly, embedded in the frame, comprising: a wind chamber plate, fixedly embedded in the frame, with one side of its height direction abutting the frame edge, the wind chamber plate having an air guide cavity inside, and an air outlet channel and an air inlet channel connected to the air guide cavity, the air outlet channel extending through the top of the frame, and the air inlet channel being located on another side of the wind chamber plate at a certain height; and a buffer plate assembly, slidably embedded in the frame, comprising: a buffer plate, a sliding member, and a slider. The moving part slides in the first groove on the bottom frame edge, and the slider slides in the first groove on the top frame edge. One side of the buffer plate in the height direction slides in contact with the side of the air cavity plate that has an air inlet channel. The other side in the height direction opposite to this side slides in contact with the frame edge of the frame. The buffer plate is configured in two states in the frame. In the first state, the buffer plate is located at the front end of the first groove, and the front end face of the buffer plate is flush with the front end face of the air cavity plate. This is suitable for environments with low wind speeds. In the second state, when the wind speed is high, the buffer plate is pushed and slid to the rear end of the first groove. The airflow is guided by the buffer plate into the air guide cavity of the air cavity plate and then discharged from the air outlet channel.

[0007] Furthermore, the two sides of the frame are provided with splicing tenons and splicing rivet grooves, and the two frames are spliced ​​together by inserting the splicing tenons into the splicing rivet grooves.

[0008] Furthermore, the buffer plate is an arc-shaped plate.

[0009] Furthermore, the air guide cavity includes: a conical air cavity, narrow at the bottom and wide at the top, with the top extending through the top edge of the frame; and an arc-shaped channel, one end of which connects to the bottom side of the arc-shaped air cavity, and the other end of which connects to the air inlet channel on the side of the air cavity plate, so that the airflow enters the conical air cavity through the arc-shaped channel and forms a vortex inside the conical air cavity.

[0010] Furthermore, the sliding component is a sliding sleeve, and auxiliary blocks are provided on both sides of the sliding sleeve, which slides in the first groove through the auxiliary blocks.

[0011] A construction site enclosure wind-resistant support structure includes the aforementioned wind-resistant enclosure structure, and further includes: a fixed base and a plurality of fixing components disposed at the bottom of the fixed base.

[0012] Furthermore, the fasteners include: a fixing nail sleeve with a sharp end at the bottom for insertion below the ground surface, and multiple through holes on the outer side; a rod, one end of which is connected to the bottom of the frame and inserted into the fixing nail sleeve to connect the frame and the fixing base; multiple fixing cones located inside the fixing nail sleeve, arranged in a circular array, with each fixing cone's tail connected to an arc-shaped plate, the lines connecting the ends of the multiple arc-shaped plates forming a ring, and a fixing groove provided on the surface of each arc-shaped plate along the direction of the ring; multiple guide telescopic rods, set on the inner wall of the arc-shaped plate and the fixing nail sleeve in the corresponding direction, which, when the rod is inserted into the fixing nail sleeve, compress the arc-shaped plate to cause the fixing cone to extend out from the through hole and insert into the soil along the direction of the corresponding guide telescopic rod on the arc-shaped plate; and an elastic ring, fitted on the ring formed by the lines connecting the multiple fixing grooves, used to reset the fixing cone after the rod is pulled out.

[0013] Furthermore, it also includes: a second slide groove and a connecting member, the connecting member being configured corresponding to the sliding member, each connecting member including: a sliding block, which slides in the second slide groove; a connecting post, one end of which is connected to the top of the sliding block and perpendicular to the top of the sliding block, and the other end of which is used to connect to the sliding member; and a buffer spring, which is configured in the second slide groove, one end of which is connected to the sliding block and the other end of which is connected to the end of the second slide groove.

[0014] Furthermore, it also includes: auxiliary fasteners, which include: a fixing block, which is fixedly connected to the bottom of the frame, and the bottom of the fixing block is provided with multiple fixing posts vertically; and an inlay groove, which is opened on the top of the fixing seat and corresponds to the position of the fixing block, and the bottom of the inlay groove is provided with multiple slots that match the fixing posts.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The frame of the enclosure structure of the present invention is provided with a wind chamber plate and a buffer plate assembly. The buffer plate is configured in two states in the frame. In the first state, the buffer plate is located at the front end of the first slide groove, and the front end face of the buffer plate is flush with the front end face of the wind chamber plate. This is suitable for environments with low wind force. In the second state, when the wind force is high, the buffer plate is pushed and slid to the rear end of the first slide groove. The airflow is guided by the buffer plate into the air guide cavity of the wind chamber plate and then discharged from the air outlet channel at the top of the frame. This not only has a strong ability to buffer wind force, but also guides the sand and dust to the top of the frame, keeping the sand and dust away from the ground of the construction site. This avoids the situation where the sand and dust directly pass through the enclosure and adhere to the ground of the construction site, sweeping up the dust on the ground.

[0017] 2. The buffer plate of the present invention is arc-shaped, and the air guide cavity includes an arc-shaped channel and a conical air cavity. The arc-shaped buffer plate, in conjunction with the arc-shaped channel, allows the airflow to be poured into the conical air cavity more smoothly. The arc-shaped channel and the bottom side of the conical air cavity are connected, so that the wind and sand airflow forms a regular vortex at the bottom of the conical air cavity and spirals up along the inner wall of the conical air cavity, offsetting the impact force of wind and sand layer by layer, and more smoothly exporting the wind and sand from the top of the frame.

[0018] 3. The present invention is provided with a fixing seat that matches the fence structure. The fixing seat can not only be more firmly fixed to the ground through the fixing member at the bottom, but also the connection between the fixing member and the frame can be more secure. Furthermore, the fixing member and the frame can be made more secure through auxiliary fixing members and connecting members.

[0019] 4. The frame of the present invention is provided with splicing tenons and splicing rivet grooves on both sides, which makes it easier to connect the two frames, and the tenon and mortise connection method can make the constructed enclosure more secure. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] Example 1:

[0030] Installing construction site fencing serves a preventative function and improves site safety. To enhance wind resistance, reinforced supports are typically welded around the perimeter, bracing diagonally between the fencing and the ground. However, these supports lack wind-guiding capabilities and are easily blown over in strong winds. During actual construction surveys, it was found that some mesh fencing panels on the market allow sand and dust to pass through the mesh, reducing the wind's impact on the panels. However, while the mesh guides air, it doesn't prevent sand and dust from entering the construction site, causing dust pollution. To address the challenge of existing fencing panels simultaneously providing both good wind protection and resistance, this embodiment proposes a wind-resistant fencing structure, such as... Figure 1 and Figure 2As shown, a wind-resistant enclosure structure is installed on a support structure fixed to the ground, including: a frame 1 and a baffle assembly 2. The baffle assembly 2 is embedded in the frame 1. The side of the frame 1 connected to the support structure is the bottom frame edge, and the frame edge opposite to the bottom is the top frame edge. A first sliding groove 11 is formed on the inner side of the bottom and top frame edges of the frame along its width direction; Figure 1-4 As shown, the baffle assembly 2 includes: an air chamber plate 3 and a buffer plate assembly 4. The air chamber plate 3 is fixedly embedded in the frame 1, and one side of its height direction is attached to the frame edge of the frame 1. The air chamber plate 3 has an air guide cavity 31 inside, and an air outlet channel 32 and an air inlet channel are connected to the air guide cavity 31. The air outlet channel 32 passes through the top of the frame 1, and the air inlet channel is opened on the other side of the air chamber plate 3 at another height. Figure 3 As shown, the buffer plate assembly 4 is slidably embedded in the frame 1, including: a buffer plate 41, a slider 42, and a slider 43. The slider 42 slides in the first groove 11 on the bottom frame edge, and the slider 43 slides in the first groove 11 on the top frame edge. One side of the buffer plate 41 in the height direction slides in contact with one side of the air cavity plate 3 where the air inlet channel 32 is provided, and the other side in the height direction opposite to this side slides in contact with the frame edge of the frame 1. The thickness of the buffer plate 41 is thinner than the thickness of the air cavity plate 3, and the buffer plate 41 is configured in two states in the frame 1. In the first state, the buffer plate 41... Located at the front end of the first chute 11, the front end face of the buffer plate 41 is flush with the front end face of the air cavity plate 3, which is suitable for environments with low wind force. In the second state, when the wind force is high, the buffer plate 41 is pushed and slid to the rear end of the first chute 11. The airflow is guided by the buffer plate 41 into the air guide cavity 31 of the air cavity plate 3 for buffering and then discharged from the air outlet channel 32 at the top of the frame. It not only has a strong ability to buffer wind force, but also guides the sand and dust to the top of the frame, keeping the sand and dust away from the ground of the construction site, thereby avoiding the situation where the sand and dust directly pass through the fence and adhere to the ground of the construction site and sweep up the dust on the ground.

[0031] like Figure 2 and Figure 3 As shown, in order to facilitate the connection of multiple enclosure frames end to end to form a closed-loop enclosure and to ensure a certain degree of connection and tightness between each frame, with adjacent frames providing mutual clamping force, splicing tenons 12 and splicing rivet grooves 13 are respectively provided on both sides of the frame 1. By inserting the splicing tenon 12 into the splicing rivet groove 13, the two frames 1 are spliced ​​together. This method is not only convenient to use, but also provides a more secure mortise and tenon connection.

[0032] In order to make it easier to install the above-mentioned fence structure on the ground and to secure it to the ground, this embodiment designs a construction site fence wind-resistant support structure. The construction site fence wind-resistant support structure includes the above-mentioned fence structure, a fixing seat 5 that matches the above-mentioned fence structure, and a plurality of fixing parts 6 set at the bottom of the fixing seat 5.

[0033] In some embodiments, in order for the fastener 6 to not only securely fix the mounting base to the ground, but also to connect and fix the mounting base and the frame together, such as... Figure 1 and Figure 5 As shown, the fixing component 6 includes: a fixing nail sleeve 61, an insert rod 67, multiple fixing spikes 63, multiple guide telescopic rods 66, and an elastic ring 65. The bottom of the fixing nail sleeve 61 is a sharp end, which can quickly break through the soil and insert below the ground surface. The fixing nail sleeve 61 is hollow inside and has no closed surface at the top. Multiple through holes 62 are opened on the outside of the fixing nail sleeve 61 for the fixing spikes 63 to extend out. The insert rod 67 has the same shape as the fixing nail sleeve 61, but is slightly smaller in size. One end of the insert rod 67 is connected to the bottom of the frame 1 and inserted into the fixing nail sleeve 61 to connect the frame 1 and the fixing seat 5. Multiple fixing spikes 63 are located inside the fixing nail sleeve 61 and are arranged in a ring array. The tail of each fixing spike 63 is connected to an arc-shaped plate. 64. Multiple arc-shaped plates 64 connected end to end form a ring. Each arc-shaped plate 64 has a fixing groove along the direction of the ring on its surface. The insert rod 67 is inserted into the fixing nail sleeve 61, which expands the ring formed by the arc-shaped plates 64 and causes the fixing cone to move. Multiple guide telescopic rods 66 are set on the inner wall of the arc-shaped plates 64 and the fixing nail sleeves 61 in their corresponding directions. When the insert rod 67 is inserted into the fixing nail sleeve 61, it squeezes the arc-shaped plates 64 so that the fixing cone 63 extends out from the through hole 62 and inserts into the soil along the direction of the guide telescopic rod 66 on its arc-shaped plate 64. An elastic ring 65 is sleeved on the ring formed by the connection of multiple fixing grooves. It can be a ring spring or other elastic return ring, such as an elastic rubber ring, and its purpose is to reset the fixing cone 63 after the insert rod 67 is pulled out.

[0034] like Figure 1 and Figure 3As shown, to make the connection between the frame and the fixed base tighter, the sliding member 42 is designed as a sliding sleeve. Auxiliary blocks are provided on both sides of the sliding sleeve, allowing it to slide within the first slide groove 11 via these auxiliary blocks. The fixed base also includes a second slide groove 51 and connecting members 7. The connecting members 7 are configured corresponding to the sliding member 42. Each connecting member 7 includes a sliding block 72, a connecting post 71, and a buffer spring 73. The sliding block 72 slides within the second slide groove 51. One end of the connecting post 71 is connected to the top of the sliding block 72 and is perpendicular to the top of the sliding block 72; the other end is used to connect to the sliding member 42. The buffer spring 73 is disposed within the second slide groove 51, with one end connected to the sliding block 72 and the other end connected to the second slide groove. At the end of 51, when the frame is installed on the base, the insert rod at the bottom of the frame is inserted into the fixing nail sleeve, and at the same time the connecting post 71 is inserted into the sliding sleeve on the frame, so that the connection between the buffer plate 41 of the buffer plate assembly and the fixing seat is tighter. When the wind force is small, the buffer spring 73 extends and pushes the sliding block 72 against the front end of the first slide groove, so that the buffer plate is against the front end of the first slide groove and the end face is flush with the air cavity plate. When the wind force is large, the wind force blows the buffer plate towards the rear end of the first slide groove. At this time, the buffer spring buffers part of the wind force and is squeezed and contracted, so that the sliding block slides to the rear end of the second slide groove and guides the wind and sand to the air guide cavities on both sides through the plate surface of the buffer plate.

[0035] To further improve the connection and tightness between the fixing base and the frame and prevent the frame from shaking in windy weather, some embodiments also include an auxiliary fixing component 8. The auxiliary fixing component 8 includes a fixing block 81 and an inlay groove 83. The fixing block 81 is fixedly connected to the bottom of the frame 1, and multiple fixing posts 82 are vertically provided at the bottom of the fixing block 81. The inlay groove 83 is opened at the top of the fixing base 5, corresponding to the position of the fixing block 81. Multiple slots 84 matching the fixing posts 82 are opened at the bottom of the inlay groove 83. When the insert rod is inserted into the fixing nail sleeve, the fixing block 81 is embedded and engaged in the inlay groove 83, and the fixing posts 82 at the bottom of the fixing block are inserted into the slots 84, making the connection between the frame and the fixing base more secure.

[0036] Example 2:

[0037] In some embodiments, in order to improve the flow of wind and sand blown towards its surface by the buffer plate 41, so that the wind and sand can enter the air guide cavity 31 along the plate surface, such as Figure 6 As shown, the buffer plate 41 is an arc-shaped plate.

[0038] However, when the arc-shaped buffer plate 41 guides the sand and dust into the air guide cavity 31, the sand and dust airflow is difficult to form a regular fluid pattern within the air guide cavity 31. This causes the sand and dust airflows introduced into the air guide cavity 31 to collide with each other, forming turbulence. This is not conducive to guiding the airflow in the air guide cavity 31 to the air outlet channel. Therefore, in order to improve the guiding effect of the air guide cavity on the airflow and enable the sand and dust airflow in the air guide cavity to form a regular vortex, thereby more efficiently exporting the airflow in the air guide cavity from the air outlet channel, such as... Figure 6 As shown, the air guide cavity also includes a conical air cavity 34 and an arc-shaped channel 33. The conical air cavity 34 is narrow at the bottom and wide at the top, with the top extending through the top edge of the frame 1. One end of the arc-shaped channel 33 is connected to the bottom side of the arc-shaped air cavity 34, and the other end is connected to the air inlet channel on the side of the air cavity plate 3. The curvature of the arc-shaped air cavity 34 and the curvature of the arc-shaped buffer plate 41 are matched to form a curvature, so that after the airflow enters the conical air cavity 34 through the arc-shaped channel 33, a vortex is formed at the bottom of the conical air cavity 34. The vortex spreads from the bottom of the conical air cavity 34 to the top, which can buffer the airflow velocity and impact force layer by layer until the airflow is guided to the outside of the frame.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
