Description

Technical Field

[0001] This utility model relates to the field of slope construction, specifically to a template structure for slope lining concrete. Background Technology

[0002] In the design of a 500kV pumped storage power station, the slopes of the outgoing tunnel, the inlet and outlet reservoirs, and the excavated slopes requiring treatment involve a large amount of reinforced concrete slope lining concrete. During the pouring of this slope lining concrete, formwork erection is necessary. Traditionally, scaffolding is erected on the slope for the installation and reinforcement of combined steel formwork. However, this method involves a large amount of scaffolding erection and dismantling work, is extremely cumbersome, and involves the management of critical or even extremely critical engineering projects, posing significant safety hazards. Utility Model Content

[0003] This utility model provides a formwork structure for slope lining concrete to solve the problems of existing technology, which uses scaffolding to install and reinforce combined steel formwork, resulting in large scaffolding erection and dismantling work, complicated construction, and numerous safety hazards.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A formwork structure for slope lining concrete includes steel formwork, longitudinal ribs, and connecting components;

[0006] The steel formwork is parallel to the slope surface;

[0007] The longitudinal ribs are provided in at least two, both of which are set on the back of the steel formwork, and each has a longitudinal installation seam in the middle. The top and bottom of the longitudinal installation seam extend beyond the top and bottom of the steel formwork, respectively.

[0008] Each longitudinal rib is equipped with two connecting components, which are used to connect the top and bottom ends of the longitudinal rib to the slope surface, respectively. The connecting components include a tapered sleeve, a first threaded rod, a pre-embedded reinforcing bar, and a clamping component. The pre-embedded reinforcing bar is set on the slope surface and is perpendicular to the slope surface. The tapered sleeve is fitted onto the first threaded rod. The top of the first threaded rod passes through the longitudinal installation joint from the top or bottom end of the longitudinal installation joint, and the clamping component presses the longitudinal rib downwards against the upper end face of the tapered sleeve. The bottom of the first threaded rod is connected to the pre-embedded reinforcing bar.

[0009] Specifically, the clamping component includes a first pressure plate and a first clamping nut. The first pressure plate is slidably disposed on the first lead screw, and the first clamping nut is threadedly connected to the first lead screw. Rotating the first clamping nut downwards clamps the first pressure plate, causing the first pressure plate to press the longitudinal rib downwards against the upper end face of the tapered sleeve.

[0010] Specifically, the lower end of the steel formwork is provided with a main crossbeam, and the main crossbeam is provided with a positioning groove that is aligned with the longitudinal installation joint; when the first threaded rod passes through the longitudinal installation joint from the bottom end of the longitudinal installation joint, the first threaded rod is located in the positioning groove.

[0011] Specifically, the steel formwork includes multiple standard formwork panels that are spliced ​​together. The edges of the standard formwork panels are provided with connecting plates. The plane of the connecting plates is perpendicular to the plane of the standard formwork panels. Connecting bolts pass through the connecting plates on adjacent standard formwork panels to splice them together to form the steel formwork.

[0012] Specifically, it also includes a second threaded rod installed on the side of the steel formwork away from the slope surface. The second threaded rod is parallel to the first threaded rod, and several second threaded rods are installed. All the second threaded rods pass through the longitudinal installation joint.

[0013] It also includes a second pressure plate and a second clamping nut. The second pressure plate is slidably mounted on the second lead screw, and the second clamping nut is threadedly connected to the second lead screw. Rotating the second clamping nut downwards presses the second pressure plate, so that the second pressure plate presses the longitudinal rib downwards onto the steel template.

[0014] Specifically, the longitudinal rib includes two first U-shaped plates with openings facing away from each other, and the longitudinal mounting seam is the gap between the webs of the two first U-shaped plates.

[0015] Furthermore, it also includes a transverse rib, which is a second U-shaped plate with an upward opening. The web of the second U-shaped plate is connected to the wing plate of the first U-shaped plate by a tension bolt.

[0016] Specifically, it also includes a walking plate; the ends of the longitudinal ribs are provided with pads parallel to the horizontal plane, the pads are arranged near the lower end of the steel template, and the two ends of the walking plate are respectively supported on the pads of the two longitudinal ribs.

[0017] Furthermore, it also includes guardrails, which are installed on the pads of two longitudinal ribs, with the guardrails positioned close to the end of the pads away from the longitudinal ribs.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] This invention utilizes a longitudinal rib with a longitudinal installation seam on the back of the steel formwork. Two first threaded rods pass through the longitudinal rib from the top and bottom of the longitudinal installation seam, respectively. With the help of clamping devices, the longitudinal rib is pressed tightly onto a tapered sleeve, thereby fixing the upper and lower positions of the steel formwork. This enables rapid formwork installation, eliminating the need for scaffolding erection and the cumbersome procedures involved. It also effectively avoids various safety hazards that may exist during scaffolding erection. The steel formwork can be dismantled simply by removing the clamping devices, which loosens the formwork from the first threaded rods. After loosening, the steel formwork can be hoisted to the next installation point using hoisting equipment, making the installation and dismantling of the steel formwork more convenient and faster.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0034] like Figure 1 and Figure 2 As shown, a formwork structure for slope lining concrete includes a steel formwork 2, longitudinal ribs 203, and connecting components.

[0035] The steel formwork 2 is parallel to the slope surface 1;

[0036] At least two longitudinal ribs 203 are provided, and both longitudinal ribs 203 are provided on the back of the steel formwork 2. Each longitudinal rib 203 has a longitudinal installation seam 204 in the middle, and the top and bottom of the longitudinal installation seam 204 extend beyond the top and bottom of the steel formwork 2, respectively.

[0037] Each longitudinal rib 203 is provided with two connecting components, which are used to connect the top and bottom ends of the longitudinal rib 203 to the slope surface 1, respectively. The connecting components include a tapered sleeve 401, a first threaded rod 301, a pre-embedded reinforcing bar 101, and a clamping member. The pre-embedded reinforcing bar 101 is set on the slope surface 1 and is perpendicular to the slope surface 1. The tapered sleeve 401 is sleeved on the first threaded rod 301. The top 301 of the first threaded rod 301 passes through the longitudinal installation seam 204 through the top or bottom end of the longitudinal installation seam 204, and the clamping member presses the longitudinal rib 203 downwards against the upper end face of the tapered sleeve 401. The bottom of the first threaded rod 301 is connected to the pre-embedded reinforcing bar 101.

[0038] In this utility model, such as Figure 1 and Figure 2 As shown, the steel formwork 2 serves as the main structure for pouring the slope-facing concrete. During installation, it is necessary to ensure that the steel formwork 2 is parallel to the slope surface 1 to ensure that the thickness of the poured slope-facing concrete is uniform.

[0039] The pre-embedded reinforcing bars 101 set on the slope surface 1 are pre-embedded according to the installation position of the steel formwork 2. The bottom of the pre-embedded reinforcing bars 101 is driven into the slope surface 1, while the top of the pre-embedded reinforcing bars 101 is located on the slope surface 1, providing a stable installation position for the installation of the steel formwork 2.

[0040] Specifically, after the steel formwork is hoisted to the predetermined position, a first threaded rod 301 passes through the bottom of the lower end of the steel formwork 2, and through the bottom end of the longitudinal installation seam 204 of the longitudinal rib 203. It then cooperates with the clamping component to press the longitudinal rib 203 downwards onto the tapered sleeve 401 on the first threaded rod 301, thereby positioning and fixing the bottom of the steel formwork 2. At the same time, a first threaded rod 301 passes through the top of the upper end of the steel formwork 2 in the same manner, and through the top end of the longitudinal installation seam 204 of the longitudinal rib 203. It then cooperates with the clamping component to press the longitudinal rib 203 downwards onto the tapered sleeve 401 on the first threaded rod 301.

[0041] Since at least two longitudinal ribs 203 are provided, and the other longitudinal ribs 203 are arranged in the same manner, that is, at least four first threaded rods 301 are provided, two located below the lower end of the steel formwork 2 and two located above the upper end of the steel formwork 2, thus defining a stable plane for the steel formwork 2. The four first threaded rods 301 provide support for the steel formwork 2, enabling it to be stably erected above the slope surface 1, forming a pouring space between the steel formwork 2 and the slope surface 1. The tapered sleeve 404, also called a reducer sleeve, serves to protect and position the first threaded rods 301 and is a commonly used structure in the field of formwork construction in the prior art.

[0042] After the first section of slope lining concrete is poured and has reached a certain strength, the clamping parts can be removed. Then, the steel formwork 2 is removed from the first threaded rod 301, and the steel formwork 2 and its auxiliary structures are hoisted as a whole and transported to the pouring position of the next section of slope lining concrete using a truck crane or other lifting equipment.

[0043] In a preferred embodiment, the clamping component includes a first pressure plate 302 and a first clamping nut 303. The first pressure plate 302 is slidably disposed on the first lead screw 301, and the first clamping nut 303 is threadedly connected to the first lead screw 301. Rotating the first clamping nut 303 downwards clamps the first pressure plate 302, so that the first pressure plate 302 presses the longitudinal rib 203 downwards onto the upper end face of the tapered sleeve 401.

[0044] This embodiment provides a specific structure for a clamping component, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the clamping component includes a first pressure plate 302 and a first clamping nut 303;

[0045] The first pressure plate 302 is slidably mounted on the first lead screw 301 and located between the first clamping nut 303 and the longitudinal rib 203. When the first clamping nut 303 is rotated, rotating it upwards (counterclockwise) is the loosening process, and rotating it downwards (clockwise) is the clamping process. Specifically, the clamping process involves rotating the first clamping nut 303 downwards, causing it to move downwards and press against the first pressure plate 302. Continuing to rotate the first clamping nut 303 will then stably and firmly press the longitudinal rib 203 onto the tapered sleeve 401 through the first pressure plate 302, thereby fixing the steel template 2.

[0046] In a preferred embodiment, the bottom of the steel formwork 2 is provided with a main crossbeam 201, and the main crossbeam 201 is provided with a positioning groove 202 that is aligned with the position of the longitudinal installation joint 204;

[0047] When the first lead screw 301 passes through the longitudinal mounting seam 204 from the bottom end of the longitudinal mounting seam 204, the first lead screw 301 is located in the positioning groove 202.

[0048] In this embodiment, specifically, as follows: Figure 3 and Figure 5 As shown, the lower end of the steel formwork 2 is provided with a main crossbeam 201, and a positioning groove 203 that is recessed upward (extending from the lower end of the steel formwork 2 to the upper end of the steel formwork 2) is provided on the main crossbeam 201. This makes it easy to align the positioning groove 202 with the first threaded rod 301 during the installation of the steel formwork 2, thereby ensuring that the lower end of the steel formwork 2 can be accurately hoisted to the predetermined position.

[0049] After the steel formwork 2 is hoisted to the predetermined position, the positioning groove 202 on the main crossbeam 201 is placed directly on the first threaded rod 301. Especially when the overall weight of the steel formwork 2 is large, and the friction provided by the clamping parts alone cannot bear the load normally, the first threaded rod 301 can support the steel formwork 2, so that the steel formwork 2 is fixed in the position along the slope surface 1, thereby avoiding the displacement of the steel formwork 2 during the pouring process.

[0050] It should be noted that in this application, the longitudinal rib 203 refers to the steel rib on the back of the steel formwork 2, that is, the vertical support of the steel formwork 2. In order to facilitate the description of its direction and structure, it is named longitudinal rib 203.

[0051] In summary, the above method enables the rapid installation of steel formwork 2 on the slope surface 1, eliminating the need for scaffolding erection as in existing technologies. This effectively simplifies the construction process and avoids the safety hazards associated with scaffolding. Furthermore, the use of clamping devices for fixing allows for rapid dismantling of the steel formwork 2 after the slope lining concrete is poured at one point. This facilitates quick formwork removal and transfer of the steel formwork 2 to the next construction site, significantly accelerating its turnover and greatly shortening the construction cycle.

[0052] In a preferred embodiment, the steel formwork 2 includes multiple standard formwork panels that are spliced ​​together. A connecting plate 502 is provided on the edge of the standard formwork 501. The plane of the connecting plate 502 is perpendicular to the plane of the standard formwork 501. Connecting bolts pass through the connecting plates 502 on adjacent standard formwork panels 501 to splice them together to form the steel formwork 2.

[0053] In this embodiment, a specific structure of a steel formwork 2 is provided, wherein, as shown in the figure... Figure 3 As shown, designing the steel formwork 2 as an integral structure composed of multiple standard formworks 501 facilitates its transportation, avoids excessive space occupation during transport, and allows for the assembly of any number of standard formworks 501 according to actual needs, effectively increasing the flexibility of the formwork structure. Furthermore, the aforementioned main beam 201 also supports the upper steel formwork 2 composed of multiple standard formworks 501, preventing the standard formworks 501 without longitudinal ribs 203 from bearing the load solely on the connecting bolts, thus optimizing the stress distribution of the standard formworks 501.

[0054] As a preferred embodiment, it also includes a second threaded rod 601 disposed on the side of the steel formwork 2 away from the slope surface 1. The second threaded rod 601 is parallel to the first threaded rod 301. Several second threaded rods 601 are provided, and all the second threaded rods 601 pass through the longitudinal installation joint 204.

[0055] It also includes a second pressure plate 602 and a second clamping nut 603. The second pressure plate 602 is slidably disposed on the second lead screw 601, and the second clamping nut 603 is threadedly connected to the second lead screw 601. Rotating the second clamping nut 603 presses the second pressure plate 602 downward, so that the second pressure plate 602 presses the longitudinal rib 203 downward onto the steel template 2.

[0056] In this embodiment, a specific installation method for the longitudinal rib 203 is provided, wherein, as shown... Figures 2-5As shown, one end of the second lead rod 601 is fixedly set on the side of the steel template 2 away from or opposite to the slope surface 1, and the other end is provided with a clamping structure (second pressure plate 602 and second clamping nut 603) with the same clamping components. The other end of the second lead rod 601 is passed through the longitudinal installation seam 204 of the longitudinal rib 203, and the second pressure plate 602 is slidably set on the second lead rod 601. Then, by rotating the second clamping nut 603, the second clamping nut 603 can firmly and stably install the longitudinal rib 203 on the steel template 2 through the second pressure plate 602, thereby realizing the rapid installation of the longitudinal rib 203. Alternatively, by rotating the second clamping nut 603 in the opposite direction, the longitudinal rib 203 can be quickly removed from the steel template 2.

[0057] In a preferred embodiment, the longitudinal rib 203 includes two first U-shaped plates with openings facing away from each other, and the longitudinal mounting seam 204 is the gap between the webs of the two first U-shaped plates.

[0058] This embodiment provides a specific structure for the longitudinal rib 203, wherein, as shown in the example... Figure 3 and Figure 5 As shown, the longitudinal installation joint 204 is formed by the gap between the webs of two first U-shaped plates. The first U-shaped plates can effectively increase the structural strength of the longitudinal rib 203 and prevent the first pressure plate 302 and the second pressure plate 602 from exerting excessive pressure on the longitudinal rib 203, which could lead to its deformation.

[0059] As a further embodiment, it also includes a transverse rib 205, which is a second U-shaped plate with its opening facing upward (away from the steel template 2), and the web of the second U-shaped plate is connected to the wing plate of the first U-shaped plate by tension bolts.

[0060] This embodiment provides a structure for strengthening the steel formwork 2, such as... Figure 3 As shown, specifically, it is the horizontal rib 205. The horizontal rib 205 refers to the steel rib on the back of the steel formwork 2, that is, the horizontal support of the steel formwork 2. For ease of description, it is named horizontal rib 205. By setting the horizontal rib 205, the lateral bending strength of the steel formwork 2 can be effectively increased, preventing the steel formwork 2 from bending laterally. The horizontal rib 205 adopts a second U-shaped plate with an upward opening, which facilitates the quick connection between the horizontal rib 205 and the longitudinal rib 203, while ensuring the connection strength between the two and preventing deformation of the horizontal rib 205 and the longitudinal rib 203 during the connection process.

[0061] In a preferred embodiment, the template structure further includes a walking plate 702;

[0062] The ends of the longitudinal ribs 203 are provided with pads 701 parallel to the horizontal plane. The pads 701 are arranged near the lower end of the steel template. The two ends of the walking plate 702 are respectively supported on the pads 701 of the two longitudinal ribs 203.

[0063] In this embodiment, a structure for construction workers to walk on is provided. Specifically, since there are multiple longitudinal ribs 203, there are also multiple support rods 701. A walking platform 702 is laid on the multiple support rods 701 to form a walking platform. Construction workers can use ladders to climb onto the platform to carry out connection construction or dismantle the steel formwork 2.

[0064] In a preferred embodiment, the template structure also includes a guardrail;

[0065] The guardrail is installed on the pads 701 of the two longitudinal ribs 203, and the guardrail is arranged close to the end of the pad 701 away from the longitudinal ribs 203.

[0066] In this embodiment, the guardrail can form a protective enclosure at the end of the pad 701 away from the slope surface, preventing construction workers from accidentally falling and effectively ensuring the safety of construction workers.

[0067] Specifically, the aforementioned guardrail includes a guardrail 703 and a horizontal railing 705; the guardrail 703 is fixedly installed at the end of the support rail 701 away from the slope surface, and the guardrail 703 is perpendicular to the horizontal plane; a pipe support 704 is installed on the guardrail 703, such as... Figure 4 As shown, the pipe frame 704 is L-shaped, with one end connected to the guardrail 703, forming an upward-opening support structure. In the same steel formwork 2, when there are two longitudinal ribs 203, the two ends of the horizontal railing 705 are placed inside the pipe frame 704 of the two guardrails 703 to form a complete protective railing. When there are more than two longitudinal ribs 203, the two ends of the horizontal railing 705 are respectively placed inside the pipe frame 704 of the outermost guardrails 703 on both sides, and the middle part of the horizontal railing 705 is placed inside the pipe frame 704 of the other guardrails 703 to form a complete protective railing, so that the protective railing can play a good protective role.

[0068] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
