Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring formwork technology, and in particular relates to a self-propelled corridor inner formwork. Background Technology

[0002] Traditional internal formwork construction often employs a disc-lock type full-span scaffolding system, where longitudinal and transverse horizontal bars, vertical bars, and external diagonal bars are all erected using steel pipes, with fixed longitudinal spacing and step distances for the vertical bars. This process has significant technical drawbacks: First, the formwork for each section of the corridor requires repeated erection and dismantling, resulting in a large investment of manpower and materials, a long scaffolding erection cycle, and severely restricting construction efficiency; second, the formwork joints are not tight, easily leading to grout leakage, affecting the quality of concrete molding; third, repeated disassembly and assembly of the formwork can easily cause deformation, reducing the flatness and rigidity of the formwork; fourth, reliance on hoisting equipment for formwork transportation and installation not only increases equipment and personnel costs but also poses high safety risks due to frequent high-altitude operations. These problems are particularly pronounced in scenarios where the working surface is limited in narrow corridor construction, urgently requiring an internal formwork technology that can reduce disassembly and assembly operations and improve construction safety and quality stability. Utility Model Content

[0003] In view of the shortcomings of the related technologies, the purpose of this utility model is to provide a self-propelled long corridor inner mold to solve the problems mentioned in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A self-propelled corridor interior model includes:

[0006] Tracks, laid on the floor of the long corridor;

[0007] A mobile trolley is mounted on a track and can move along the length of the track.

[0008] Template frame, the template frame is set above the mobile trolley;

[0009] Panel, the panel is fixedly installed on the outside of the template frame;

[0010] The lifting and adjusting mechanism is connected to the bottom of the formwork frame. The lifting and adjusting mechanism is used to extend and retract the formwork frame to two states: one is the pouring operation state, that is, the formwork frame is raised and suspended above the mobile trolley and the two are not in contact; the other is the demolding state, that is, the formwork frame is lowered and placed on the mobile trolley, which carries it and moves synchronously with it.

[0011] In some embodiments, the mobile trolley includes multiple trolley units spaced apart along the length of the track. Each trolley unit includes a rectangular frame structure and a set of moving wheels. The rectangular frame structure is formed by welding double-channel steel, and the set of moving wheels is installed at the bottom of the rectangular frame structure to roll along the track.

[0012] In some embodiments, each trolley unit has multiple transverse support channels inside its rectangular frame structure. The transverse support channels are spaced apart along the length of the rectangular frame structure and welded to the double-channel steel to form a grid-like support structure.

[0013] In some embodiments, the template frame includes multiple vertical waler groups, which are spaced apart along the length of the corridor. Each vertical waler group is formed by connecting two symmetrically arranged vertical walers to form an overall frame structure.

[0014] In some embodiments, each vertical waler includes a first channel steel member arranged vertically, a second channel steel member and a third channel steel member arranged horizontally; the second channel steel member is fixedly connected to the upper end of the first channel steel member, the third channel steel member is fixedly connected to the lower middle part of the first channel steel member, and the extension directions of the second channel steel member and the third channel steel member are both perpendicular to the first channel steel member.

[0015] In some embodiments, the upper end of the lifting adjustment mechanism is fixedly connected to the bottom of the third channel steel member, and the lower end of the lifting adjustment mechanism abuts and supports the bottom plate of the corridor during the pouring operation.

[0016] In some embodiments, the formwork frame also includes a horizontal adjustment mechanism connected between the opposite ends of the third channel steel members of two symmetrically arranged vertical walers. The horizontal adjustment mechanism is used to adjust the formwork frame to shrink and separate from the poured concrete structure when the formwork is demolded.

[0017] In some embodiments, a steel plate is welded to the end of the second channel steel member away from the first channel steel member, and the steel plates of the two symmetrically arranged vertical walers are rotatably connected by a hinge shaft, the axis of which is parallel to the length of the corridor.

[0018] In some embodiments, the panel includes a side panel arranged vertically and a top panel arranged horizontally. Both the side panel and the top panel are composed of multiple sub-panels spliced ​​together. An elastic seal is provided between adjacent sub-panels. The elastic seal is configured to form a sealing interface when the panels are spliced ​​together to prevent grout leakage during the concrete pouring process.

[0019] In some embodiments, the track is an I-beam track, which is anchored to the floor of the corridor by a plurality of expansion bolts spaced at intervals.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Compared with traditional full-span scaffolding construction, the self-propelled corridor inner formwork provided by this utility model can be moved as a whole through the cooperation of rails and mobile trolleys, eliminating the repeated erection and dismantling of formwork, greatly reducing the investment of manpower and hoisting equipment, and lowering construction costs; the formwork frame has high rigidity and is equipped with sealing parts at the joints, which effectively avoids grout leakage and deformation, improves the quality of concrete forming, and significantly enhances construction safety.

[0022] 2. The self-propelled corridor inner formwork provided by this utility model can quickly switch between the pouring and dismantling states of the formwork skeleton by means of the lifting and horizontal adjustment mechanisms, shortening the construction cycle of a single section. Combined with the continuous operation capability of the mobile trolley, it significantly improves construction efficiency. The overall structural design increases the reuse rate of the formwork, reduces material consumption, and reduces the risk of high-altitude operations, thus achieving both economic and safety benefits.

[0036] See appendix Figures 1 to 7 This invention provides an illustrative embodiment of the self-propelled corridor inner mold proposed in this utility model. The self-propelled corridor inner mold includes a track 1, a mobile trolley 3, a template frame 4, a panel 5, and a lifting and adjusting mechanism 6.

[0037] Track 1 is laid on the floor slab 2 of the long corridor; the mobile trolley 3 is mounted on track 1 and can move along the length of track 1; the formwork frame 4 is located above the mobile trolley 3; the panel 5 is fixedly installed on the outside of the formwork frame 4; the lifting and adjusting mechanism 6 is connected to the bottom of the formwork frame 4, and the lifting and adjusting mechanism 6 is used to extend and retract to allow the formwork frame 4 to be in two states: one is the pouring operation state, see appendix. Figure 6 The first state is when the template frame 4 is lifted and suspended above the moving trolley 3 without contact between them; the second state is when the template is disassembled, see appendix. Figure 7 That is, the template frame 4 is lowered and placed on the mobile trolley 3, and is carried by the mobile trolley 3 and moves synchronously with it.

[0038] See appendix Figure 4 and Figure 5 The mobile trolley 3 includes multiple trolley units arranged at intervals along the length of the track 1. Each trolley unit includes a rectangular frame structure 31 and a set of moving wheels 32. The rectangular frame structure 31 is formed by welding double-channel steel. The set of moving wheels 32 is installed at the bottom of the rectangular frame structure 31 and can roll along the track 1. In this embodiment, the mobile trolley 3 is driven by a winch. With the help of the guide of the track 1 and the cooperation of the set of moving wheels 32, the mobile trolley 3 can move horizontally, giving full play to the synergistic effect of the track 1 and the mobile trolley 3, and simplifying the overall displacement operation of the template.

[0039] Each trolley unit's rectangular frame structure 31 is also equipped with multiple transverse support channel steels 33. The transverse support channel steels 33 are arranged at intervals along the length of the rectangular frame structure 31 and welded and fixed with double-section channel steels to form a stable grid-like support structure.

[0040] In this embodiment, the specific structure of a single trolley unit is as follows: 8m long and 1.8m wide, with double [20 channel steel on both sides, connected as a whole by [20@1000mm channel steel, and four 120mm diameter rollers installed at the bottom for easy movement. Considering transportation limitations, the trolley is manufactured and transported in sections. On-site, two independent 8×1.8m trolley units are assembled into one unit using a 25t truck crane.

[0041] The template frame 4 includes multiple vertical waler groups 41, which are spaced apart along the length of the corridor. Each vertical waler group 41 consists of two symmetrically arranged vertical walers 411 connected to form an overall frame structure. In this embodiment, the vertical walers 411 are made of double-layered [12@1000mm channel steel, and the tie rods are made of Φ20 steel bars@1000×1200. The tie rods are used to connect the core mold and the outer mold. 36 vertical walers 411 are required for one side of the corridor.

[0042] The template frame 4 is assembled on-site. First, one vertical waler 411 is fixed, then another is hoisted to the preset position, connected to the insertion hole, and the hinge bolt is inserted to complete the installation of one vertical waler group 41. All vertical waler groups 41 are installed in sequence to form the template frame 4.

[0043] Each vertical waler 411 includes a vertically arranged first channel steel member 4111, a horizontally arranged second channel steel member 4112, and a third channel steel member 4113; the second channel steel member 4112 is fixedly connected to the upper end of the first channel steel member 4111, and the third channel steel member 4113 is fixedly connected to the lower middle part of the first channel steel member 4111, and the extension directions of the second channel steel member 4112 and the third channel steel member 4113 are both perpendicular to the first channel steel member 4111.

[0044] See appendix Figure 2 In this embodiment, the vertical waler 411 further includes a plurality of obliquely arranged fourth channel steel members 4114. One end of one fourth channel steel member 4114 is fixedly connected to the middle of the first channel steel member 4111, and the other end is correspondingly connected to the end of the second channel steel member 4112 away from the first channel steel member 4111. Another fourth channel steel member 4114 has one end fixedly connected to the middle of the first channel steel member 4111, and the other end is correspondingly connected to the end of the third channel steel member 4113 away from the first channel steel member 4111. This forms a triangular stable support structure. The obliquely arranged fourth channel steel members 4114 can further enhance the overall rigidity and deformation resistance of the vertical waler 411. During the concrete pouring process, they can effectively disperse lateral pressure and prevent the vertical waler 411 from shifting due to uneven stress, thereby ensuring the stability of the formwork frame 4 and ensuring the accuracy of the concrete forming dimensions.

[0045] The upper end of the lifting and adjusting mechanism 6 is fixedly connected to the bottom of the third channel steel member 4113, and the lower end of the lifting and adjusting mechanism 6 abuts and supports the long corridor floor 2 in the pouring operation state. Specifically, in this embodiment, the lifting and adjusting mechanism 6 includes a connecting rod whose upper end is fixedly connected to the bottom of the third channel steel member 4113, and a support rod threadedly connected to the lower end of the connecting rod; the support rod is divided into a threaded end and a non-threaded end, wherein the threaded end forms a threaded engagement with the connecting rod, and the non-threaded end is a flat support end; by rotating the support rod, the thread engagement length between it and the connecting rod can be adjusted to realize the overall height extension and contraction adjustment. In the pouring operation state, the non-threaded end of the support rod abuts and supports the long corridor floor 2.

[0046] The template frame 4 also includes a horizontal adjustment mechanism 42, which is connected between the opposite ends of the third channel steel members 4113 of the two symmetrically arranged vertical walers 411. The horizontal adjustment mechanism 42 is used for telescopic adjustment to allow the template frame 4 to shrink and separate from the poured concrete structure 8 in the demolding state. Specifically, in this embodiment, the horizontal adjustment mechanism 42 includes a first nut and a second nut respectively hinged to the opposite ends of the two third channel steel members 4113, and an adjusting screw passing through the first nut and the second nut. The two ends of the adjusting screw form positive and negative thread engagements with the first nut and the second nut respectively. By rotating the adjusting screw, the first nut and the second nut can be driven to move closer or further apart along the screw axis, thereby realizing the telescopic adjustment of the horizontal length, so that the template frame 4 shrinks and separates from the poured concrete structure 8 in the demolding state.

[0047] See appendix Figures 1 to 3 A steel plate 7 is welded to the end of the second channel steel member 4112 away from the first channel steel member 4111. The steel plates 7 of the two symmetrically arranged vertical walers 411 are rotatably connected by a hinge shaft 71, the axis of which is parallel to the length of the corridor. In this embodiment, the steel plate 7 is 10mm thick, with a connecting hole at its center. It is connected by a φ25mm hinge shaft 71, and a 5mm wide grout-stopping strip is pasted at the joint.

[0048] Panel 5 includes a vertically arranged side panel 51 and a horizontally arranged top panel 52. Both side panel 51 and top panel 52 are assembled from multiple sub-panels 5 and are made of 5mm thick steel plate. Elastic seals are provided between adjacent sub-panels 5, configured to form a sealed interface when the panels 5 are assembled to prevent grout leakage during concrete pouring. Specifically, in this embodiment, the elastic seal is a grout-stop strip. During installation, the side panel 51 and top panel 52 are processed and transported in sections, and then assembled on site using a 25t truck crane. During assembly, grout-stop strips are pasted between adjacent sub-panels before being tightened with screws. The entire installation process is monitored by surveyors to ensure that the panel elevation and position meet design requirements.

[0049] Panel 5 is processed in a specialized processing workshop using a dedicated steel platform. Before processing, the platform is leveled using a level instrument. After panel 5 is laid, it is clamped and fixed to the platform to prevent local deformation during welding and ensure panel flatness. During processing, to ensure the integrity of the template and the accuracy of the connecting bolt holes, an integral processing method is adopted. The original design joints are fixed by spot welding, improving template processing efficiency and quality.

[0050] See appendix Figure 1In this embodiment, the template frame 4 also includes transverse ribs 43. The transverse ribs 43 are made of [8 channel steel, and there are multiple transverse ribs 43. The multiple transverse ribs 43 are arranged at intervals of 300mm between the template frame 4 and the panel 5. The arrangement of transverse ribs 43 can effectively enhance the connection stability between the template frame 4 and the panel 5. Through the interval arrangement of multiple channel steels, the lateral pressure generated during concrete pouring can be evenly distributed to the template frame 4, avoiding excessive local stress on the panel 5 and causing deformation, thereby ensuring the flatness of the panel, improving the surface quality of concrete molding, and further strengthening the rigidity and deformation resistance of the overall template structure.

[0051] Track 1 is an I-beam steel track, which is anchored to the floor slab 2 of the long corridor by multiple expansion bolts spaced at intervals. The type of I-beam steel track 1 is determined based on the self-weight of the corridor formwork and the weight of the concrete during pouring, to meet actual construction requirements. In this embodiment, track 1 uses P43 steel rails, with an upper width of 70mm, a lower width of 114mm, and a height of 140mm. The multiple expansion bolts used to fix track 1 are spaced 2 meters apart.

[0052] See appendix Figure 6 The chamfering of the long corridor has been completed. Before erecting the four formwork frames, horizontal points were marked on the chamfered concrete. The lifting and adjusting mechanism 6 was used to raise the formwork frame 4 to the design elevation, with the position determined according to the chamfering front line. Then, the horizontal adjusting mechanism 42 was used to ensure that the dimensions of the formwork frame 4 met the design requirements. One jacking screw was installed every 2 meters at the bottom of each side of the corridor, 60cm from the wall, along with ten 10t jacks, all positioned at the vertical waler 411. Based on the weight of the formwork, the number of jacking screws and jacks was confirmed to meet the requirements.

[0053] See appendix Figure 7 When the concrete structure 8 reaches 75% of its design strength, the inner formwork is removed. First, the lifting adjustment mechanism 6 is retracted by 2cm to relieve it of stress. Then, the effective length of the horizontal adjustment mechanism 42 is adjusted to move the formwork away from the concrete structure 8. By repeatedly adjusting the lifting adjustment mechanism 6 and the horizontal adjustment mechanism 42, the formwork is placed on the mobile trolley 3 and transported to the next section.

[0054] In the above illustrative embodiments, the self-propelled corridor internal formwork significantly reduces manpower and equipment input compared to traditional methods, greatly lowering construction costs. By optimizing the formwork erection and dismantling methods, repeated erection and dismantling procedures are eliminated, significantly improving construction efficiency, shortening the construction period, and making formwork assembly and dismantling operations convenient and efficient. Construction safety is greatly enhanced, avoiding the safety hazards caused by repeated crane assembly and dismantling in traditional methods. At the same time, the overall movement of the formwork is achieved through the cooperation of the trolley and the track, making operation simple and convenient, with strong applicability, comprehensively improving the economy, safety, and quality stability of construction.

[0055] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
