Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a protective device for building construction. Background Art

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where construction operations are carried out is called the building construction site. Building construction is a production activity in which people use various building materials and construction machinery and equipment to carry out production activities for building various building products in a certain space and time according to a specific design blueprint.

[0003] At present, when carrying out high-rise building construction, it is necessary to erect a safety protection device around the building to prevent workers from accidentally falling and causing casualties. The protection devices adopted at the present stage are relatively simple. Only a layer of barrier net is erected every three to four floors on the building. When a worker accidentally falls, his body directly impacts the barrier net, which will cause impact damage to the worker's body. At the same time, there is also a risk that the worker will roll or bounce out from the barrier net due to excessive impact when falling, and it is impossible to safely hold the worker, so the protection effect is not good.

[0004] Chinese patent document CN115929061A discloses a building construction protection device, including: a protection device, a falling support component, a buffer component and an interception component. Among them, a sliding rod is installed on the protection device, and the falling support component is connected to the sliding rod. The falling support component is used to hold the accidentally falling worker and fall along the sliding rod. The buffer component is used to reduce the falling speed of the falling support component. The interception component is arranged below the buffer component and is used to intercept and stop the falling support component described above; however, there are still the following defects in the implementation process:

[0005] Although the device in the above document can catch the falling worker through the barrier net, and then decelerate and buffer the descending barrier net through the buffer component until it stops descending at the interception component, effectively reducing the impact on the worker from the barrier net when falling, thus ensuring the personal safety of the worker, the device in the above document cannot provide edge protection. In the process of current building construction, it is necessary to first carry out foundation pit excavation work. At this time, it is necessary to set up a guardrail on the side facing the air to prevent people from falling in and avoid major personal accidents. In the process of installing the guardrail, most of the time, the method of inserting screws at the columns is used for fixation, which takes a lot of time and affects the progress of building construction. Content of the Utility Model

[0006] The purpose of the utility model is to provide a protective device for building construction to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A protective device for building construction comprises a protective body; support columns are inserted on both sides of the protective body, and a buffer plate is detachably connected to the front end of the protective body; an installation component, the installation component is used to quickly install the support column, and the installation component is connected to the support column; and a splicing component is used to fix the position of the buffer plate, and the splicing component is connected to the protective body.

[0009] The above-mentioned technical solution is adopted. In this solution, the support columns are installed around the foundation pit, and the protective body is inserted from top to bottom into the two sides of the support columns to realize the protection of the foundation pit. In this process, the installation components are used to realize the rapid installation of the support columns, avoiding the need to nail the screws one by one during installation, resulting in slow installation efficiency of the support columns, and consuming more time and manpower in the subsequent disassembly and assembly process. At the same time, the buffer plate is installed under the action of the splicing components, which improves the overall buffering effect of the protective body and avoids the damage of the protective body to be unable to be used normally when impacted by external force.

[0010] A further improvement of the technical solution of the utility model is that: the installation component includes an extrusion rod inserted into the inner wall of the supporting column, a pushing rod is inserted into the inner side wall of the extrusion rod, a limiting block is fixedly connected to the inner side wall of the extrusion rod, the bottom of the extrusion rod is rotatably connected to an arc piece, the bottom of the arc piece is fixedly connected to a resistance column, the bottom of the resistance column is fixedly connected to a first spring, the bottom of the supporting column is fixedly connected to a limiting base, a plurality of telescopic arc plates are slidably connected at the middle position of the limiting base, the inner side walls of the telescopic arc plates are fixedly connected to support plates, and both sides of the telescopic arc plates are fixedly connected to connecting pieces.

[0011] The above-mentioned technical solution is adopted, in which the position of the supporting column is fixed by setting a limit base and inserting it vertically into the soil. In order to increase the stability of the supporting column, the staff can rotate the push rod to push the extrusion rod downward, and the limit block can prevent the push rod from detaching. At this time, the arc piece moves downward under the action of the extrusion rod, and the resistance column at its bottom and the first spring assist the arc piece to move.

[0012] A further improvement of the technical solution of the utility model is that the telescopic arc plates are distributed in a circular array, the telescopic arc plates are connected by connecting pieces, and the telescopic arc plates and the support plates are an integrated structure.

[0013] With the above technical solution, during the process of the arc-shaped piece moving downward, the outwardly bent part of the arc-shaped piece gradually squeezes the support plate to cause displacement, thereby pushing the telescopic arc-shaped plate to expand outward. At this time, the diameter of the expanded telescopic arc-shaped plate is larger than the diameter of the limit base, increasing the overall stress area of the limit base and enhancing the installation stability of the support column.

[0014] A further improvement of the technical solution of the present utility model lies in that: a second spring is fixedly connected to the bottom of the support plate.

[0015] With the above technical solution, a second spring is arranged inside the support plate in this solution to assist the telescopic arc-shaped plate to move on the surface of the limit base.

[0016] A further improvement of the technical solution of the present utility model lies in that: one side of the support plate away from the telescopic arc-shaped plate is in contact with the outer side wall of the arc-shaped piece.

[0017] With the above technical solution, the top of the arc-shaped piece in this solution has a tendency to bend outward, the bottom has a tendency to bend inward, and the shape contour of the bottom bend is adapted to the shape contour of the support plate.

[0018] A further improvement of the technical solution of the present utility model lies in that: the splicing component includes first clamping blocks symmetrically installed at the front end of the protection main body. Second clamping blocks are inserted into the inner side walls of the first clamping blocks. A protection plate is fixedly connected to the side of the second clamping block away from the first clamping block. A plurality of buffer arch-shaped pieces arranged linearly are fixedly connected to the top of the protection plate. Third springs are symmetrically installed on both sides of the protection plate.

[0019] With the above technical solution, at the connection position between the protection plate and the buffer plate in this solution, there are also a plurality of buffer arch-shaped pieces. The buffer arch-shaped pieces are in a shape like the Chinese character 'ji'. When the buffer plate is impacted by an external force, the buffer performance of the buffer plate is improved by using the buffer arch-shaped pieces and the third springs, avoiding the phenomenon that the protection main body is damaged by an external impact and cannot be used.

[0020] A further improvement of the technical solution of the present utility model lies in that: the second clamping block and the protection plate are of an integral structure, and the shape contours of the second clamping block and the first clamping block are adapted to each other.

[0021] With the above technical solution, the first clamping block and the second clamping block are of matching shapes. During use, the second clamping block is aligned with the first clamping block and inserted from top to bottom to realize the connection between the first clamping block and the protection plate.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0023] 1. The utility model provides a protective device for building construction. By installing the support columns around the foundation pit and inserting the protective main body into both sides of the support columns from top to bottom, the protection of the foundation pit is realized. In this process, the installation component is used to quickly install the support columns, avoiding the slow installation efficiency of the support columns caused by driving in screws one by one during installation, consuming a lot of time and manpower in the subsequent disassembly and assembly processes. At the same time, under the action of the splicing component, the buffer plate is installed, improving the overall buffer effect of the protective main body and preventing the protective main body from being damaged and unable to be used normally when impacted by external forces.

[0024] 2. The utility model provides a protective device for building construction. After the limit base is vertically inserted into the soil, the position of the support column is fixed. To increase the stability of the support column, the staff can rotate the push rod to push the extrusion rod downward. The limit block can prevent the push rod from detaching. At this time, the arc-shaped piece moves downward under the action of the extrusion rod, and the abutting column and the first spring at its bottom assist the arc-shaped piece to move. During the downward movement of the arc-shaped piece, the gradually extruded support plate by the outwardly bent part of the arc-shaped piece moves, thereby pushing the telescopic arc-shaped plate to expand outward. At this time, the expanded diameter of the telescopic arc-shaped plate is greater than the diameter of the limit base, increasing the overall stress area of the limit base and the installation stability of the support column.

[0025] 3. The utility model provides a protective device for building construction. The first clamping block and the second clamping block are provided with matching shapes. During use, the second clamping block is aligned with the first clamping block and inserted from top to bottom to realize the connection between the first clamping block and the protection plate. At the connection position between the protection plate and the buffer plate, a plurality of buffer arch-shaped pieces are also provided. The buffer arch-shaped pieces are in a "J" shape. When the buffer plate is impacted by external forces, the buffer performance of the buffer plate is improved by using the buffer arch-shaped pieces and the third spring, avoiding the phenomenon that the protective main body is damaged and unable to be used when impacted by external forces.

Specific embodiments

[0036] The following further describes the present utility model in detail with reference to the embodiments:

[0037] Embodiment 1

[0038] As Figure 1 shown, the present utility model provides a protection device for building construction, including a protection main body 1; support columns 2 are inserted on both sides of the protection main body 1, and a buffer plate 5 is detachably connected to the front end of the protection main body 1; an installation component for quickly installing the support columns 2, the installation component is connected to the support columns 2; a splicing component for fixing the position of the buffer plate 5, the splicing component is connected to the protection main body 1.

[0039] In this embodiment, since the foundation pit excavation work needs to be carried out before building construction, in order to prevent personnel from falling into the foundation pit, a guardrail needs to be set up to prevent personnel from falling into the foundation pit. By installing the support columns 2 around the foundation pit and inserting the protection main body 1 into both sides of the support columns 2 from top to bottom, the protection of the foundation pit is realized. In this process, the installation component is used to quickly install the support columns 2, avoiding the slow installation efficiency of the support columns 2 caused by individually driving screws during installation, and consuming a lot of time and manpower in the subsequent disassembly and assembly process. At the same time, under the action of the splicing component, the installation of the buffer plate 5 is realized, improving the overall buffer effect of the protection main body 1 and avoiding damage to the protection main body 1 and inability to be used normally when impacted by external forces.

[0040] Embodiment 2

[0041] As Figures 2 - 6As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the mounting assembly includes an extrusion rod 7 inserted into the inner wall of the support column 2, a push rod 6 is inserted into the inner wall of the extrusion rod 7, a limiting block 16 is fixedly connected to the inner wall of the extrusion rod 7, an arc piece 8 is rotatably connected to the bottom of the extrusion rod 7, a resisting column 10 is fixedly connected to the bottom of the arc piece 8, a first spring 11 is fixedly connected to the bottom of the resisting column 10, a limiting base 9 is fixedly connected to the bottom of the support column 2, and the limiting base 9 A plurality of telescopic arc plates 12 are slidably connected at the middle position, support plates 13 are fixedly connected to the inner side walls of the telescopic arc plates 12, connecting pieces 14 are fixedly connected to both sides of the telescopic arc plates 12, the telescopic arc plates 12 are distributed in a circular array, the telescopic arc plates 12 are connected by the connecting pieces 14, the telescopic arc plates 12 and the support plates 13 are an integrated structure, a second spring 15 is fixedly connected to the bottom of the support plate 13, and the side of the support plate 13 away from the telescopic arc plate 12 is in contact with the outer side wall of the arc piece 8.

[0042] In this embodiment, since the support columns 2 are currently mostly installed by screws, it takes a lot of time and manpower to disassemble and assemble the support columns 2, which affects the progress of the construction.

[0043] By setting a limit base 9 and inserting it vertically into the soil, the position of the support column 2 is fixed. To increase the stability of the support column 2, the staff can rotate the push rod 6 to push the extrusion rod 7 downward, wherein the limit block 16 can prevent the push rod 6 from detaching. At this time, the arc piece 8 moves downward under the action of the extrusion rod 7, and the resistance column 10 at its bottom and the first spring 11 assist the arc piece 8 to move.

[0044] Specifically, when the arc-shaped piece 8 moves downward, the shape contour of its outer wall squeezes the support plate 13 to move outward. It should be noted that the top of the arc-shaped piece 8 tends to bend outward, and the bottom tends to bend inward, and the shape contour of the bent bottom adapts to the shape contour of the support plate 13. In the process of the arc-shaped piece 8 moving downward, the part of the arc-shaped piece 8 that bends outward gradually squeezes the support plate 13 to find displacement, thereby pushing the telescopic arc plate 12 to expand outward. At this time, the expanded diameter of the telescopic arc plate 12 is greater than the diameter of the limiting base 9, which increases the overall force-bearing area of the limiting base 9 and increases the stability of the installation of the support column 2.

[0045] Furthermore, a second spring 15 is provided inside the support plate 13 to assist the telescopic arc plate 12 to move on the surface of the limiting base 9 , wherein the connecting piece 14 has a certain elasticity to connect each telescopic arc plate 12 .

[0046] Example 3

[0047] like Figure 7 andFigure 8 As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the splicing component includes a first clamping block 3 symmetrically installed at the front end of the protection main body 1. Second clamping blocks 17 are inserted into the inner side walls of the first clamping blocks 3. A protection plate 4 is fixedly connected to the side of the second clamping block 17 away from the first clamping block 3. A plurality of buffer arch-shaped sheets 18 arranged linearly are fixedly connected to the top of the protection plate 4. Third springs 19 are symmetrically installed on both sides of the protection plate 4. The second clamping block 17 and the protection plate 4 are of an integral structure, and the shape profiles of the second clamping block 17 and the first clamping block 3 are adapted to each other.

[0048] In this embodiment, by setting the first clamping block 3 and the second clamping block 17 to have adapted shapes, during use, the second clamping block 17 is aligned with the first clamping block 3 and inserted from top to bottom to realize the connection between the first clamping block 3 and the protection plate 4. At the connection position between the protection plate 4 and the buffer plate 5, a plurality of buffer arch-shaped sheets 18 are also provided. The buffer arch-shaped sheets 18 are in a shape like the Chinese character 'ji'. When the buffer plate 5 is impacted by an external force, the buffer performance of the buffer plate 5 is improved by using the buffer arch-shaped sheets 18 and the third springs 19, so as to avoid the phenomenon that the protection main body 1 is damaged by an external impact and cannot be used.

[0049] The working principle of the construction protection device will be specifically described below.

[0050] As Figures 1 - 8As shown in the figure, first, the limit base 9 is vertically inserted into the soil to fix the position of the support column 2. To increase the stability of the support column 2, the staff can rotate the push rod 6 to push the extrusion rod 7 downward. The limit block 16 can prevent the push rod 6 from detaching. At this time, the arc-shaped piece 8 is displaced downward under the action of the extrusion rod 7. The abutting column 10 and the first spring 11 at its bottom assist the arc-shaped piece 8 in displacement. When the arc-shaped piece 8 is displaced downward, the shape profile of its outer wall squeezes the support plate 13 to move outward. It should be noted that the top of the arc-shaped piece 8 tends to bend outward, and the bottom tends to bend inward, and the shape profile of the bottom bend is adapted to the shape profile of the support plate 13. During the downward movement of the arc-shaped piece 8, the outward-bending part of the arc-shaped piece 8 gradually squeezes the support plate 13 to cause displacement, thereby pushing the telescopic arc-shaped plate 12 to expand outward. At this time, the diameter of the expanded telescopic arc-shaped plate 12 is larger than the diameter of the limit base 9, increasing the overall force-bearing area of the limit base 9 and the stability of the installation of the support column 2. A second spring 15 is arranged inside the support plate 13 to assist the telescopic arc-shaped plate 12 in moving on the surface of the limit base 9. The connecting piece 14 has a certain elasticity to connect each telescopic arc-shaped plate 12. Since the shapes of the first clamping block 3 and the second clamping block 17 are adapted to each other, during use, the second clamping block 17 is aligned with the first clamping block 3 and inserted from top to bottom to realize the connection between the first clamping block 3 and the protection plate 4. At the connection position between the protection plate 4 and the buffer plate 5, a plurality of buffer arch-shaped pieces 18 are also provided. The buffer arch-shaped pieces 18 are in a zigzag shape. When the buffer plate 5 is impacted by an external force, the buffer arch-shaped pieces 18 and the third spring 19 are used to improve the buffering performance of the buffer plate 5, avoiding the phenomenon that the protection main body 1 is damaged by an external impact and cannot be used.

[0051] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
