Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to an integrated formwork support device. Background Technology

[0002] With the rapid development of society and the economy, the construction of many engineering structures often requires excavation of foundation pits along existing routes, such as urban utility tunnels and bridge abutments. During the excavation process, steel sheet piles are usually used for the sidewall support of the foundation pit to prevent the soil from collapsing during construction. If the structure is constructed using cast-in-place methods, formwork installation and fixing are also required. In this case, the cross-sectional excavation area of ​​the entire foundation pit is large, the construction procedures are numerous, and the turnover of formwork support is complex, thus reducing construction efficiency. Moreover, such projects have long longitudinal construction routes, and the long-term turnover of formwork support consumes a large amount of material, which greatly increases construction costs.

[0003] Especially for highway reconstruction and expansion projects, it is often necessary to construct pier caps in the median strip of existing roads. The number of pier caps is large, and the available cross-sectional area for excavation pits in the existing median strip is small. Traditional construction methods require a large amount of formwork support, and large excavation areas can damage existing roads, thus affecting traffic and resulting in high overall construction costs. Therefore, it is necessary to upgrade the formwork support system to avoid a series of problems arising from large excavation areas and the simultaneous installation of formwork support.

Detailed Implementation

[0020] Example 1 like Figure 1-4In the present invention, an integrated formwork support device includes multiple symmetrically arranged columns 1. Two opposing columns 1 are connected by connecting beams 4 to form a portal frame. Two adjacent portal frames are connected by transverse formwork 2 and longitudinal formwork 3 to form a support body. The outer side of the transverse formwork 2 is also provided with walers 5 for clamping.

[0021] like Figure 5 In the construction of long-distance foundation pits such as pipe corridors, this device can be laid along the direction of the foundation pit. Only the horizontal templates 2 need to be installed at both ends. The horizontal templates on the middle portal frame can be removed. It is simple to operate and has good results.

[0022] Both column 1 and connecting beam 4 are made of steel to ensure their structural strength. At the same time, the modular design ensures that the overall installation, disassembly and adjustment are convenient. The distance of the portal frame can be flexibly adjusted according to the length of the connecting beam 4, and the installation sequence can be adjusted according to different geological conditions.

[0023] The connecting beam 4 can also serve as a guide connecting frame. During construction, two reference guide piles are first driven. The guide piles are square piles, meaning that the guide piles are driven but not pulled out. Square frames are installed at both ends of the connecting beam 4. The outer side of the frame has installation positions that are fixed to the connecting beam 4. The square frame can be fitted onto the outer perimeter of the column 1. Then, using this as a reference, the square frame of the four-hole guide connecting frame is installed on it. The subsequent guide piles are driven onto the square frame, thus ensuring the overall installation accuracy.

[0024] The portal frame is surrounded by horizontal template 2 and vertical template 3, which can stably bear the pressure from the side soil or concrete in the foundation pit. The overall operation is simple and the effect is good.

[0025] like Figure 6-14 In the preferred embodiment, the first slot 101 and the second slot 102 are symmetrically arranged on both sides of the column 1, and the horizontal template 2 and the vertical template 3 are respectively inserted into the first slot 101 and the second slot 102.

[0026] The quick-release design ensures convenient hoisting, provides better support stability, and facilitates efficient demolding after the concrete has reached its full strength.

[0027] In a preferred embodiment, an installation groove 103 is provided between the two second slots 102, and the connecting beam 4 includes a fixing part 401. Connecting heads 403 are provided on both sides of the fixing part 401, and the connecting heads 403 are located in the installation groove 103.

[0028] The dimensions of the portal frame can be easily changed via the connecting beam 4, ensuring precise and reliable overall locking. The mounting groove 103 serves both bottom bearing and lateral fixing functions, providing strong overall load-bearing capacity and evenly distributing loads to guarantee the structural strength of the support structure and enable it to cope with various working conditions.

[0029] In a preferred embodiment, a plurality of first through holes 105 and second through holes 106 are vertically and alternately arranged in the mounting groove 103. A plurality of third through holes 405 are provided through the connector 403. A second threaded hole 404 is provided on one side of the third through hole 405. The locking rod 7 passes through the second through hole 106 and the second threaded hole 404. The positioning rod 10 passes through the first through hole 105 and the third through hole 405. A first threaded hole 108 is provided through the second slot 102. The first threaded hole 108 is positioned opposite the first through hole 105. A screw 8 for limiting the positioning rod 10 is provided in the first threaded hole 108.

[0030] The positioning rod 10 can accurately position the connector 403. During installation, the positioning rod 10 is installed into the first through hole 105 and the connector 403 by tapping. This improves the situation of loss of precision due to wear and tear of various components caused by repeated installation and disassembly and repeated use, and avoids the problem of deformation failure due to the above problems. At the same time, after the positioning rod 10 is installed and the transverse template 2 is inserted and installed in place, the end of the screw 8 abuts against the side of the second slot 102 opposite to the positioning rod 10, avoiding the problem of the positioning rod 10 axial movement and slippage due to construction vibration. The locking rod 7 locks the connector 403 from the other side and is firmly installed on the column 1, fixing the connecting beam 4 and the column 1 to form the main body. The column 1 ensures its own positional accuracy during insertion and installation, so the connecting beam 4 can check and calibrate the above accuracy.

[0031] In a preferred embodiment, the two sides of the fixing part 401 are connected by the extension part 402 and the connector 403 respectively. The ends of the fixing part 401 and the extension part 402 are connected by the flange plate 408. The extension part 402 is connected to the connector 403 by the reinforcing rib 407. Two guide heads 406 are provided in parallel on the connector 403. The inner side of the mounting groove 103 is provided with a triangular groove 107 that matches the guide head 406.

[0032] The flange plate 408 allows for quick installation and removal, and the length of the extension part 402 can be adjusted as needed to meet various application requirements. To further ensure easy alignment, during installation, the connecting beam 4 is hoisted and then slid into the triangular groove 107 of the mounting groove 103 using the guide head 406, resulting in a better overall installation effect.

[0033] In a preferred embodiment, the waler 5 includes a plug-in plate 501, the inner side of which is provided with a plurality of protrusions 502, the protrusions 502 are attached to the outer side of the transverse template 2, the outer side of the plug-in plate 501 is attached to the side wall of the first slot 101, and the protrusions 502 are detachably provided with a suspension cable 6 for demolding.

[0034] The bottom of the plug plate 501 has a beveled cut facing the center of the column 1, ensuring stability during insertion and allowing for cleaning of dirt and grime from the inside of the first slot 101. The protruding strip 502, as the part in contact with the transverse template 2, ensures the overall stability of the transverse template 2 in both length and height directions, preventing bending and deformation due to uneven loads on both sides over long-term use. The hammering process involves gradual contact, and after complete fit, the friction reaches its maximum value, resulting in the ideal mold-closing state. When demolding is required, the waler 5 is hoisted out using the suspension cable 6, facilitating demolding of the transverse template 2. The waler 5 is made in the form of a blade pile, hammered downwards with cylindrical steel. This not only ensures the transverse template 2 fits against the inner wall of the first slot 101 but also provides space for the transverse template 2 to retract after use, facilitating demolding.

[0035] Generally, the length of the foundation pit is greater than its width. Therefore, walers are set on the transverse formwork 2. This is especially important for pipe gallery construction, where the length is several times the width. Setting walers on the transverse formwork 2 ensures the overall structural strength and construction stability. When the transverse formwork 2 and the longitudinal formwork 3 are of similar length and relatively long, a clearance groove 104 can be set inside the second slot 102 to install walers 5 at the longitudinal formwork 3, thus ensuring the rigidity of the overall support structure.

[0036] In the preferred embodiment, the inner side of the first slot 101 is also provided with a clearance slot 104, the top of the column 1 is provided with a fixed seat 9, the adjusting rod 11 is threadedly connected to the fixed seat 9, the adjusting rod 11 is provided with a plurality of conical sleeves 12, the size of the conical sleeves 12 gradually increases from top to bottom along the height direction, the two sides of the plug plate 501 are provided with contact plates 503, the contact plates 503 are provided with a plurality of wedge heads 504, the slope of the wedge heads 504 and the conical sleeves 12 are matched, and the conical sleeves 12 are used to adjust the degree of compression between the waler 5 and the column 1.

[0037] Within the clearance groove 104, which serves as the installation space for the drive component capable of further locking the waler 5, the overall locking is direct and stable. Rotating the adjusting rod 11 changes its height, thereby driving the conical sleeve 12 to complete the up-and-down position adjustment. During the rotation of the conical sleeve 12, its slope remains consistent. Gradually approaching or moving away from the wedge head 504, it can apply force or release force on the waler 5. Since the size of the conical sleeve 12 gradually increases from top to bottom along the height direction, the size of the wedge head 504 corresponding to the conical sleeve 12 gradually decreases from top to bottom along the height direction. This avoids interference during the installation and disassembly of the waler 5, and the overall operation is simpler, with multiple points of force application, resulting in better performance.

[0038] In a preferred embodiment, a locking head 506 is provided on the upper side of the wedge head 504, and a constraint groove 505 is formed between two adjacent wedge heads 504. Two third threaded holes 901 are symmetrically provided on the fixing seat 9, and the adjusting rod 11 passes through the third threaded hole 901. A first mark 109 and a second mark 110 are provided on the top of the column 1. An alignment edge line 902 and a third mark 903 are provided on the outer side of the fixing seat 9. The alignment edge line 902 and the third mark 903 are aligned with the first mark 109 and the second mark 110, respectively.

[0039] The locking head 506 and the constraint groove 505 cooperate to relatively limit the movement range of the conical sleeve 12 that it mates with, thereby ensuring safer overall adjustment. At the same time, when installing the fixing seat 9, the first mark 109 and the second mark 110 ensure the installation accuracy when reused. The adjusting rod 11 and the mounting sleeve 12 can be taken out by removing the fixing seat 9. In actual use, they can be fixed to the top of the column 1 by screw fixing or spot welding. The operation is simple and the fixation is stable.

[0040] Compared to ordinary plug-in structures, the design concept of this scheme is completely different. Due to the natural and unavoidable wear and tear caused by repeated installation and disassembly, which leads to a decrease in installation accuracy, this scheme initially sets a certain gap between the longitudinal template 3 and the inner side of the first slot 101 to provide installation space for the waler 5. The installation of the waler 5 compensates for the aforementioned installation accuracy problem. Therefore, within a certain range of wear, this scheme can ensure that the longitudinal template 3 is tightly attached to the first slot 101 of the column 1, ensuring that both sides can stably bear the lateral pressure from the outer soil or the inner concrete. At the same time, the removal of the waler 5 provides sufficient clearance and demolding space for the longitudinal template 3. The design is ingenious and easy to use.

[0041] like Figure 15-18 In the preferred embodiment, the column 1 includes a first connecting column 15 and a second connecting column 16. The first connecting column 15 is located at both ends of the support body, and the second connecting column 16 is located in the middle of the support body. The transverse template 2 and the longitudinal template 3 are respectively abutted against the side walls of the first connecting column 15 and the second connecting column 16 by the first wedge plate 13. The first wedge plate 13 is provided with a pull rope 14. The top of the first connecting column 15 and the second connecting column 16 is also detachably provided with a scissor brace 20.

[0042] During construction, to further improve the efficiency and reduce the difficulty of formwork removal, the columns 1 are fabricated as the first connecting column 15 and the second connecting column 16 respectively. Simultaneously, it is ensured that the surface of the support platform is free of grooves, and "h"-shaped openings are provided at both ends of the formwork. This allows the columns to be firmly fixed to the side walls of the first connecting column 15 and the second connecting column 16 under the action of the first wedge plate 13. Since a certain distance is maintained between the columns 1 and the inner wall 21 of the foundation pit, after the formwork is poured, the first wedge plate 13 is released to both sides via the pull rope 14 during dismantling, ensuring that the formwork has room to retract. The formwork is then removed using hoisting equipment. Because the two ends of the support structure bear lateral pressure from the inner wall 21 of the foundation pit, scissor braces 20 are used to fully fix the first connecting column 15 and its adjacent second connecting column 16 to improve the overall structural strength and ensure stable support.

[0043] In the preferred embodiment, the outer sides of the second connecting column 16, the transverse template 2, and the longitudinal template 3 are successively supported against the inner wall 21 of the foundation pit by the first support plate 17, the second wedge plate 19, and the second support plate 18. The second wedge plate 19 is inserted into the first support plate 17 and the second support plate 18 respectively.

[0044] During use, the stability of lateral support is ensured by the cooperation of multiple support plates. The first support plate 17, the second wedge plate 19, and the second support plate 18 work together. By changing the position of the second wedge plate 19, the support gap between the template and the inner wall 21 of the foundation pit is filled, and the template is stably supported in the designed position. After use, the template can be easily disassembled by pulling rope 14. At the same time, when installing multiple second wedge plates 19, their wedge-shaped directions are kept in the same direction, which facilitates blind disassembly. The second wedge plates 19 can be led out of the foundation pit by pulling rope 14.

[0045] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
