Description

Technical Field

[0001] The utility model relates to a set of temporary hole reservation forming and protection components, specifically, a protection component integrating temporary hole reservation forming used in green building construction, mainly used for reserving pipeline channels such as temporary water use, temporary fire protection water use, temporary power use, and concrete pump pipes during construction. It is flexible and convenient to use, and the protection is safe and reliable, belonging to the technical field of building construction protection. Background Art

[0002] Generally speaking, with the improvement of environmental protection awareness, the construction engineering industry is gradually transforming towards green development. Green buildings, green construction, etc. have become important development directions in the construction engineering field. The requirements for green construction at the construction site are becoming increasingly strict, requiring enterprises to implement standardized management and construction.

[0003] For the convenience of construction and the passage and transportation of personnel and materials, temporary holes can be seen everywhere at each construction site. However, since such holes are relatively small (the long side is less than 500 mm) and the holes need to be used repeatedly, the safety protection of the holes is not qualified. In recent years, major accidents caused by inadequate management of such small holes have been common. Moreover, unqualified quality of temporary hole plugging is also a common quality problem on construction sites. If not taken seriously, such holes pose great safety and quality hazards; thus, it can be seen that the size and quality of the hole opening directly determine whether the protection is safe and reliable.

[0004] After retrieval, the Chinese utility model patent with the publication number CN207700723U discloses a reserved hole standardized and openable protection device. Although this protection device can realize the plugging and protection of reserved holes, since the shape and size of the plugged reserved holes are not completely opened according to the construction qualification requirements, there will be a situation where when plugging some unqualified holes, due to the defects in the plugged holes, it will directly lead to difficulties and dangers in the process of using this protection device to protect the above unqualified holes. For example, when opening the protection device, some building materials or due to the carelessness of the operator will directly fall to the next floor without a buffer function through the hole, bringing potential safety hazards. In short, it is often very inconvenient.

[0005] Therefore, the key to solving the above technical problems is to develop a set of temporary hole reservation forming and protection components used in green building construction that are used in combination with a protective temporary hole and a protection device. Summary of the Invention

[0006] In view of the many defects and deficiencies in the above-mentioned background technology, the present utility model has made improvements and innovations, aiming to provide a protective component that integrates the functions of forming and protecting temporary openings in green building construction, which can be used in combination. The protective cover plate can ensure complete coverage of the opening when closed, effectively prevent objects from falling or people from accidentally entering, and improve the overall safety of the construction site; when opened, it can provide necessary access and exits while achieving a small lower opening design, making it more convenient to enter and exit the opening, especially for the transportation and handling of construction workers, equipment, and materials, without being restricted by the lower space; the large upper design not only enhances the overall protection ability of the opening but also reduces the sense of insecurity of surrounding pedestrians through good visual effects, which is beneficial to the management and maintenance of public areas.

[0007] To solve the above problems and achieve the above invention purpose, a protective component that integrates the functions of forming and protecting temporary openings in green building construction of the present utility model is realized by adopting the following design structure and the following technical solutions:

[0008] As an improvement of a protective component that integrates the functions of forming and protecting temporary openings in green building construction of the present utility model, it includes:

[0009] A temporary opening embedded mold (1), which is used to form a temporary opening (81) on the concrete floor slab (8), and is used to form a temporary opening (81) after demolding.

[0010] A temporary opening protection mechanism, which includes:

[0011] A first fixing plate (2), which is fixedly connected to the concrete floor slab (8) at one end of the temporary opening (81).

[0012] A protective cover plate (3), one end of which is connected to the first fixing plate (2) through a hinge member (4), and a cover plate locking ring (5) is also provided at the other end of the protective cover plate (3).

[0013] A second fixing plate (6), the lower end of which is fixedly connected to the concrete floor slab (8) at the other end of the temporary opening (81), and a locking component (7) that cooperates with the cover plate locking ring (5) to complete the locking work is provided at the upper end of the second fixing plate (6).

[0014] As an improvement of the above of the present utility model, the temporary opening embedded mold (1) is a hollow mold box with a large opening at one end and a small opening at the other end.

[0015] As a further improvement of the above-mentioned utility model, the pre-embedded mold (1) for the temporary opening is in a rhombus structure, and the lower opening of the mold box of this rhombus structure is small, while the upper opening is large.

[0016] As a further improvement of the above-mentioned utility model, the first fixing plate (2) is an overall flat, slender plate-shaped member, and through holes (21) are formed through the plate-shaped member, and the through holes (21) are bolt holes.

[0017] As a further improvement of the above-mentioned utility model, the protective cover plate (3) is an overall square plate-shaped member, which is used to cover the upper part of the temporary opening (81).

[0018] As a further improvement of the above-mentioned utility model, the hinge member (4) is a 180° flat-opening hinge.

[0019] As a further improvement of the above-mentioned utility model, the cover plate locking ring (5) is in a "C-shaped" or "arch-shaped" structure; the cover plate locking ring (5) is connected to the middle part of the outer side of the free end of the protective cover plate (3) by screws or bolts.

[0020] As a further improvement of the above-mentioned utility model, the second fixing plate (6) is an overall flat, slender plate-shaped member, and through holes (61) are formed through the plate-shaped member, and the through holes (61) are bolt holes.

[0021] As a further improvement of the above-mentioned utility model, the locking assembly (7) includes a fixing ring (71) and a locking member (72), and the locking member (72) is an L-shaped bolt; the shape of the fixing ring (71) is the same as that of the cover plate locking ring (5), both are in a "C-shaped" or "arch-shaped" structure; and the two are arranged on the same horizontal plane.

[0022] As a further improvement of the above-mentioned utility model, warning signs (31) with yellow and black intervals are painted on the protective cover plate (3).

[0023] The working principle is as follows: When the protection component used for forming and reserving temporary openings in a green building construction with the above-mentioned designed structure is in use, the operator only needs to transport the component of the present utility model to the designated construction position by manual or corresponding equipment for installation as a standby.

[0024] During installation, the operator only needs to open a temporary opening (81) at a reasonable position on the concrete floor slab (8) according to the construction requirements. When opening the temporary opening (81), the operator only needs to install the temporary opening embedded mold (1) to the reasonable position of the concrete floor slab (8) to be opened. During installation, the temporary opening embedded mold (1) is embedded and installed synchronously with the concrete floor slab (8). When installing the temporary opening embedded mold (1), it should be firmly fixed to avoid displacement during the pouring process of the concrete floor slab (8). Finally, when the structure of the concrete floor slab (8) is formed, after removing the temporary opening embedded mold (1), a reserved opening with a rhombus structure with a small lower opening and a large upper opening, that is, the temporary opening (81), is obtained for construction.

[0025] During construction, the operator can carry out the up and down transportation of construction materials through the temporary opening (81).

[0026] Finally, as time goes by, when the construction work is completed or the temporary opening (81) is not needed temporarily, the operator only needs to use the hinge member (4) of the present utility model to connect the first fixing plate (2) and the protective cover plate (3) to achieve the movable opening and closing of the temporary opening (81). Finally, the locking assembly (7) is locked and fixed with the cover plate locking ring (5) arranged at the free end of the protective cover plate (3) and the second fixing plate (6) as a whole to achieve the firm closing of the temporary opening (81), or by pulling out the locking member (72), the protective cover plate (3) is opened to achieve the opening of the temporary opening (81). At the same time, a yellow and black warning sign (31) is painted on the protective cover plate (3) to play a safety warning role.

[0027] Finally, after all the construction work positions are installed and disassembled, according to actual needs, the temporary opening (81) is roughened later, and it is checked whether reinforcement bars need to be planted according to the design requirements. The bottom film is set, and the concrete is poured and cured to complete the hole plugging.

[0028] The beneficial effects of the present utility model compared with the prior art are:

[0029] 1. The structure of the present utility model is simple, reasonable and novel. Since the protective cover plate (3) adopts a hinge design, on the one hand, it is easy to operate and maintain. The hinge design enables the cover plate to be conveniently opened and closed, facilitating the necessary inspection, maintenance or repair work for construction workers; this operation is more flexible and efficient than a fixed cover plate; on the other hand, the safety is enhanced. The hinge-type structure and other protective cover plates can ensure that the opening is completely covered when closed, effectively preventing objects from falling or people from straying in, improving the overall safety of the construction site; when opened, it can provide necessary access and exit.

[0030] 2. In this utility model, the temporary opening embedded mold (1) is adopted to design the temporary opening with a smaller lower opening and a larger upper opening. Therefore, on the one hand, the safety is improved. The smaller lower end can effectively prevent objects or personnel from slipping or falling from below the opening, reducing accidental risks; the larger upper end can better block objects or debris that may fall from above the opening, protecting construction workers and pedestrians around from being injured. On the other hand, the design of the smaller lower opening makes it more convenient to enter and exit the opening. Especially for the transportation and handling of construction workers, equipment, and materials, it is smoother and not restricted by the lower space; the design of the larger upper end not only improves the overall protection ability of the opening but also reduces the sense of insecurity of surrounding pedestrians through good visual effects, which is beneficial to the management and maintenance of public areas.

[0031] 3. Another aspect of this utility model adopting the temporary opening embedded mold (1) is that it can enhance the protection effect. Designing a temporary opening with a larger upper opening and a smaller lower opening can form an effective protection barrier visually and functionally. The design of the larger upper end can better cover the entire opening, preventing materials, tools, etc. from accidentally falling, and at the same time reducing the clutter in the construction site.

[0032] 4. Another aspect of this utility model adopting the temporary opening embedded mold (1) is that it can achieve construction convenience. The design of the smaller lower opening makes it more convenient to enter and exit the opening. Especially for the transportation and handling of construction workers, equipment, and materials, it is smoother and not restricted by the lower space; the design of the larger upper end not only improves the overall protection ability of the opening but also reduces the sense of insecurity of surrounding pedestrians through good visual effects, which is beneficial to the management and maintenance of public areas.

[0033] 5. The protective cover plate of this utility model uses local materials, saving costs. It is a movable type. The protective cover plate can be normally opened and closed, reused, and has great safety guarantees.

[0034] 6. The construction materials used for each component of this utility model are basically made by simply processing waste materials such as construction site templates, steel bars, and galvanized thin steel plates on the spot. It can save construction consumables to the greatest extent, and the construction method is simple, having good economy and environmental protection in green building construction.

[0035] 7. Since a yellow and black warning sign is painted on the protective cover plate (3) of this utility model, the position of this device can be clearly marked at night, in a dark indoor environment, and in an underground construction environment, effectively playing a role of safety reminder, improving the visibility, being easy for people to distinguish, and increasing the safety in construction and life.

[0051] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the technical solutions of the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0052] As Figures 1 to 6 shown, a protection component integrating temporary opening reservation and forming in green building construction includes:

[0053] A temporary opening embedded mold 1, which is used to form the temporary opening 81 on the concrete floor slab 8 and is used to form the temporary opening 81 after form removal;

[0054] Temporary opening protection mechanism, the temporary opening protection mechanism includes:

[0055] The first fixing plate 2 is fixedly connected to the concrete floor slab 8 at one end of the temporary opening 81;

[0056] The protection cover plate 3, one end of the protection cover plate 3 is connected to the first fixing plate 2 through a hinge 4, and a cover plate locking ring 5 is further provided at the other end of the protection cover plate 3;

[0057] The second fixing plate 6, the lower end of the second fixing plate 6 is fixedly connected to the concrete floor slab 8 at the other end of the temporary opening 81, and a locking component 7 for cooperating with the cover plate locking ring 5 to complete the locking work is provided at the upper end of the second fixing plate 6.

[0058] In the present utility model, since the protection cover plate 3 adopts a hinge design, on the one hand, it is easy to operate and maintain. The hinge design enables the cover plate to be conveniently opened and closed, facilitating the construction personnel to carry out necessary inspections, maintenance or repair work; this operation is more flexible and efficient compared with the fixed cover plate. On the other hand, the safety is enhanced. The hinge-type structure and other protection cover plates can ensure that the opening is completely covered when closed, effectively preventing objects from falling or people from straying in, improving the overall safety of the construction site; when opened, it can provide necessary access and egress.

[0059] Furthermore, as Figure 6 shown, the temporary opening embedded mold 1 is a hollow mold box with a large opening at one end and a small opening at the other end.

[0060] Specifically, as Figure 6 shown, the temporary opening embedded mold 1 is a rhombus structure, and the lower end of the mold box of this rhombus structure has a small opening and the upper end has a large opening.

[0061] In the present utility model, since the temporary opening is designed with a small opening at the lower end and a large opening at the upper end by using the temporary opening embedded mold 1, on the one hand, the safety is improved. The smaller lower end can effectively prevent objects or people from slipping or falling from below the opening, reducing the accident risk; the larger upper end can better block the objects or debris that may fall from above the opening, protecting the construction personnel and the surrounding pedestrians from being injured;

[0062] On the other hand, by using the temporary opening embedded mold 1, the protection effect can be enhanced. Designing a temporary opening with a large opening at the upper end and a small opening at the lower end can form an effective protection barrier visually and functionally. The large upper end design can better block the entire opening, preventing materials, tools, etc. from accidentally falling, and at the same time reducing the clutter in the construction site;

[0063] On the other hand, the adoption of the temporary opening embedded mold 1 can also achieve construction convenience. The design with a small lower opening makes it more convenient to enter and exit the opening, especially for the transportation and handling of construction workers, equipment, and materials, without being restricted by the lower space. The design with a large upper part not only improves the overall protection ability of the opening but also reduces the sense of insecurity of surrounding pedestrians through a good visual effect, which is beneficial to the management and maintenance of public areas.

[0064] Furthermore, the first fixing plate 2 is an overall flat and slender plate-shaped member, and through holes 21 are formed through the plate-shaped member. The through holes 21 are bolt holes.

[0065] Furthermore, the protective cover plate 3 is an overall square plate-shaped member for covering above the temporary opening 81.

[0066] Furthermore, the hinge member 4 is a 180° flat-opening hinge.

[0067] Furthermore, the cover plate locking ring 5 is a "C-shaped" or "arch-shaped" structure; the cover plate locking ring 5 is connected to the middle part of the outer free end of the protective cover plate 3 by screws or bolts.

[0068] Furthermore, the second fixing plate 6 is an overall flat and slender plate-shaped member, and fixing holes 61 are formed through the plate-shaped member. The fixing holes 61 are bolt holes.

[0069] Furthermore, the locking assembly 7 includes a fixing ring 71 and a locking member 72. The locking member 72 is an L-shaped bolt; the shape of the fixing ring 71 is the same as that of the cover plate locking ring 5, both being "C-shaped" or "arch-shaped" structures; and the two are arranged on the same horizontal plane.

[0070] Furthermore, a yellow and black warning sign 31 is painted on the protective cover plate 3.

[0071] Since a yellow and black warning sign is painted on the protective cover plate 3 of the present utility model, the position of the device can be clearly marked at night, in dark indoor environments, and underground construction environments, which can effectively play a role in safety reminder, improve visibility, be easy for people to distinguish, and increase safety in construction and daily life.

[0072] In summary, a more specific implementation manner of the present utility model is as follows:

[0073] The specific operation principle of a protective component integrating temporary opening reservation and forming in a green building construction using the above design structure is as follows:

[0074] Step 1. Prefabricate the embedded mold 1 for the temporary opening on-site: On-site, according to the size of the temporarily reserved opening 81, use the waste formwork on the construction site to piece together a rhombus-shaped embedded mold 1 for the temporary opening. The size of the lower opening of the rhombus-shaped embedded mold 1 for the temporary opening is the same as the size of the reserved opening, the side length of the upper opening is increased by 100 mm, and the vertical height of the rhombus-shaped embedded mold 1 for the temporary opening is increased by 50 mm compared with the slab thickness. In this embodiment, the aperture of the lower opening of the embedded mold 1 for the temporary opening is 100x100 mm, the aperture of the upper opening is 200x200 mm, and the height is 200 mm. The size can be adjusted according to the on-site situation, and the long side of the upper opening is not greater than 500 mm

[0075] Step 2. Install the embedded mold 1 for the temporary opening: The embedded mold 1 for the temporary opening is pre-embedded and installed synchronously with the concrete slab 8. When installing the embedded mold 1 for the temporary opening, it should be firmly fixed to avoid displacement during the concrete slab pouring process.

[0076] Step 3. Install the hole protection cover plate: After the concrete slab 8 is formed, remove the rhombus-shaped embedded mold 1 for the temporary opening to obtain a rhombus-shaped reserved opening with a small lower opening and a large upper opening, that is, the temporary opening 81. Then, use a 20-mm-thick waste wooden board to make a protection cover plate 3 to completely cover the opening. The edge of the protection cover plate 3 extends out of the opening by not less than 150 mm. A 20-mm-thick first fixing plate 2 is fixed to the concrete slab with bolts. The two wooden boards are connected by a 180° flat-opening hinge, that is, an articulated part 4, so that the 180° flexible opening of the hole protection cover plate 3 can be realized.

[0077] Step 4. Install the bolt and bolt hole: Fix a second fixing plate 6 on the other side of the hole wooden board. Use a 100-mm-long waste smooth round steel bar with a diameter of φ8 as a simple bolt, that is, a locking part 72. Make two simple bolt holes with a galvanized thin steel plate with a thickness of φ1.5 mm and fix them on the second fixing plate 6 and the protection cover plate 3 respectively to form a fixing ring 71 and a cover plate locking ring 5 respectively, so as to realize the locking function of the hole protection cover plate.

[0078] Step 5. Paint safety signs: Paint yellow and black warning signs 31 on the protection cover plate 3 with paint. The width of the sign line is 50 to 100 mm, and the inclination angle with the protection cover plate is 45°.

[0079] Step 6. Seal the temporary hole: When the hole needs to be sealed later, first roughen the hole surface, check whether reinforcement implantation is required according to the design requirements, weld the newly added steel bars to the original slab steel bars, set the bottom formwork, and pour concrete. The strength grade of the concrete used for sealing should be one level higher than the strength grade of the original slab concrete and should not be lower than C25. After curing and water blocking, the hole should also be caulked with waterproof ointment.

[0080] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
