Technical Field

[0001] This utility model relates to the field of track beam technology, and in particular to a support device for a template. Background Art

[0002] The track beam serves as both a load-bearing and guiding structure for vehicles, thus requiring high standards for both material and manufacturing precision during construction. In terms of materials, a steel-concrete composite beam is typically used, with concrete poured on top of the steel beam. Construction involves erecting formwork on top of the steel beam, pouring concrete into the formwork, and then removing the formwork and its supporting structure after completion.

[0003] In the existing technology, the support system for the concrete formwork of the straddle-type monorail steel-concrete composite beam bridge deck is complex in structure and consumes a large amount of steel. At the same time, it requires high precision in the installation and processing of the support device, resulting in high cost. The installation of the formwork support device on the construction site is difficult and the dismantling is complicated, which affects the construction progress. Utility Model Content

[0006] Therefore, by setting support components on the steel beam contact rail to support the formwork, and then setting limiting components on the support components to limit the formwork on both sides in the width direction, this not only ensures the reliability of the formwork support device for supporting the formwork, but also simplifies the structure of the formwork support device, thereby improving construction convenience and shortening the construction cycle.

[0007] In some examples of this utility model, the limiting member includes two shoulder straps, which are respectively disposed on both sides of the template width direction and extend in the template height direction. One end of each shoulder strap in the height direction is connected to the support member, and the two shoulder straps are respectively limited and cooperated with the two sides of the template width direction.

[0008] In some examples of this utility model, the limiting member further includes a pull rod, which passes through the other end of the two shoulder straps in the height direction and connects and fixes the two shoulder straps.

[0009] In some examples of this utility model, the height of the shoulder strap is greater than the height of the template, and the pull rod is located above the template.

[0010] In some examples of this utility model, there are multiple limiting members, and the multiple limiting members are used to be spaced apart in the length direction of the template.

[0011] In some examples of this utility model, the support device of the template further includes a connector, which is used to pass through both sides of the template in the width direction and connect the two sides of the template in the width direction.

[0012] In some examples of this utility model, there are multiple connectors, and the multiple connectors are spaced apart in the length direction of the template.

[0013] In some examples of this utility model, multiple connectors and multiple limiting members are alternately arranged in sequence along the length direction of the template.

[0014] In some examples of this utility model, the upper end of the support member is provided with a fixing member. There are two fixing members, which are respectively used to connect and fix to both sides of the template in the width direction. The two fixing members are respectively connected to the two back straps. The two ends of the fixing members corresponding to the length direction of the template protrude from the support member.

[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0027] Reference below Figure 1-Figure 2 Description of a template support device 100 according to an embodiment of the present utility model.

[0028] Combine Figure 1-Figure 2 As shown, the template support device 100 according to this utility model mainly includes: a steel beam contact rail, a support member 20, and a limiting member 30. The support member 20 is disposed on the steel beam contact rail and is used to mount the template 200. Specifically, the steel beam contact rail is disposed on the steel beam, and the support member 20 is disposed on the steel beam contact rail. The support member 20 can support the template 200, thus fixing the template 200 above the steel beam contact rail. During the construction of the steel-concrete composite beam, the template 200 for pouring the bridge deck concrete 300 can be erected above the steel beam. Furthermore, by adjusting the length of the support member 20, the height of the template 200 relative to the steel beam contact rail can be adjusted to ensure that the construction of the steel-concrete composite beam meets the design requirements.

[0029] Furthermore, the limiting component 30 is disposed on the support component 20, and the limiting component 30 is used to limit the movement of both sides of the template 200 in the width direction. Specifically, the support component 20 is also provided with the limiting component 30. After the template 200 and the support component 20 are installed, the limiting component 30 can limit the movement of both sides of the template 200 in the width direction. This can fix the width of the template 200 and make the width of the template 200 match the width of the steel beam to meet the design requirements of the steel-concrete composite beam.

[0030] Therefore, in this embodiment of the present invention, the template 200 is fixed to the steel beam contact rail only by the support member 20 and the limiting member 30, with the steel beam contact rail as the support. The support member 20 is used to support the template 200, and the limiting member 30 is used to limit the template 200 on both sides in the width direction. This not only ensures the reliability of the support device 100 for the template 200 and ensures the structural stability of the template 200 on the steel beam, but also simplifies the structure of the support device 100, reduces the amount of steel used in the support device 100, increases the number of turnovers, and reduces construction costs, thereby improving construction convenience and shortening the construction cycle.

[0031] Combine Figure 1 As shown, the limiting member 30 includes two shoulder straps 31, which are respectively disposed on both sides of the template 200 in the width direction and extend in the height direction of the template 200. One end of each shoulder strap 31 in the height direction is connected to the support member 20, and the two shoulder straps 31 respectively cooperate with the two sides of the template 200 in the width direction for limiting. Specifically, the limiting member 30 includes two shoulder straps 31, which are respectively disposed on both sides of the template 200 in the width direction to ensure the symmetry of the shoulder straps 31 in the width direction of the template 200. Both shoulder straps 31 extend in the height direction of the template 200 to increase the contact area between the shoulder straps 31 and the template 200, which helps to improve the limiting reliability of the limiting member 30 in limiting the template 200.

[0032] Furthermore, one end of each of the two shoulder straps 31 in the height direction is connected to the support member 20, which allows the limiting member 30 to be connected and fixed to the support member 20, thereby improving the reliability of the limiting member 30 in limiting the template 200 on the support member 20. The two shoulder straps 31 respectively cooperate with the limiting members on both sides of the template 200 in the width direction, which can restrict the structure on both sides of the template 200 width to remain fixed, and ensure that the position of the template 200 width on the support member 20 is fixed, so as to limit the width of the template 200 to be compatible with the width of the steel beam.

[0033] Combine Figure 1 As shown, the limiting member 30 also includes a tie rod 32, which passes through the other ends of the two shoulder straps 31 in the height direction and connects and fixes the two shoulder straps 31. This arrangement allows the tie rod 32 to limit the distance between the two shoulder straps 31 in the width direction of the template 200. The support member 20 fixes one end of the two shoulder straps 31, and the tie rod 32 restricts the other ends of the two shoulder straps 31. Thus, the width of the template 200 is limited by the shoulder straps 31 on both sides of the template 200 in the width direction, ensuring that the width of the template 200 remains constant above the steel beam, so that the concrete 300 meets the construction requirements of the bridge deck.

[0034] Combine Figure 1 and Figure 2 As shown, the height of the carrying strap 31 is greater than the height of the template 200. This ensures that the top of the carrying strap 31 extends beyond the top of the template 200, facilitating the connection between the tie rod 32 and the carrying strap 31 and improving construction convenience. The tie rod 32 is located above the template 200, allowing for easy fixing of the tie rod 32 to the upper end of the carrying strap 31. This enhances the reliability of the limiting component 30 in limiting the width of the template 200, thereby ensuring the structural reliability of the template 200 on the steel beam contact rail.

[0035] Combine Figure 2As shown, there are multiple limiting members 30, which are spaced apart along the length of the formwork 200. Specifically, in actual construction, the formwork 200 is composed of multiple shorter segments, and its length can be designed and spliced ​​according to the actual requirements of the steel-concrete composite beam. Adjacent segments are connected by bolts, and sealing strips are used to seal the joints. Therefore, multiple limiting members 30 are provided along the length of the formwork 200, and these limiting members 30 are spaced apart. This ensures that the width of the formwork 200 remains fixed along its length, thereby guaranteeing the structural reliability of the formwork 200 and ensuring the accuracy and safety of the concrete 300 pouring within it. This arrangement ensures the quality of the bridge deck concrete 300 and guarantees the driving comfort of vehicles.

[0036] Combine Figure 1 As shown, the template support device 100 also includes a connector 40, which is used to pass through both sides of the template 200 in the width direction and connect the two sides of the template 200 in the width direction. This configuration allows the template 200 to be connected in the width direction via the connector 40. Both the connector 40 and the tie rod 32 in the limiting member 30 can limit the width of the template 200 on both sides, thus increasing the reliability of the template support device 100 in limiting the width of the template 200. During the assembly of the template 200, the width of the template 200 can be positioned first via the connector 40, thus keeping the width of the template 200 fixed during the splicing process.

[0037] Combine Figure 2 As shown, there are multiple connectors 40, which are spaced apart along the length of the template 200. Specifically, each segment is provided with a connector 40. After multiple segments are spliced ​​into the template 200, the multiple connectors 40 can be spaced apart along the length of the template 200. This ensures that the width of each segment is fixed, thereby ensuring the structural stability of the template 200 as its length increases.

[0038] Combine Figure 2As shown, multiple connectors 40 and multiple limiting members 30 are alternately arranged along the length of the template 200. Specifically, in the embodiment of this utility model, both the connectors 40 and the limiting members 30 can limit the width of the template 200. The connectors 40 fix the width of the template 200 in the splicing segments of the template 200, and the limiting members 30 strengthen the fixation of the width of the template 200 after the template 200 is set on the support member 20. Therefore, in the spliced ​​template 200 structure, the multiple connectors 40 and multiple limiting members 30 are alternately arranged along the length of the template 200, which helps to improve the uniformity of stress on the template 200, the uniform distribution of stress on the template 200, thereby improving the structural reliability of the template 200 and the installation accuracy of the template 200. This arrangement helps to ensure the quality of the bridge deck concrete 300 and the driving comfort of vehicles on the bridge.

[0039] Combine Figure 1 and Figure 2 As shown, the upper end of the support member 20 is provided with two fixing members 21, which are respectively used to connect and fix to both sides of the template 200 in the width direction. The two fixing members 21 are respectively connected to two carrying straps 31, and the two ends of the fixing members 21 protrude from the support member 20 in the length direction of the template 200. Specifically, in the embodiment of this utility model, the support member 20 and the carrying straps 31 are connected by fixing members 21. The fixing members 21 include, but are not limited to, channel steel. Two channel steels are back to back to form a fixing member 21. The upper end of the support member 20 is provided with two fixing members 21, which are respectively provided on both sides of the template 200 in the width direction, so as to correspond to the carrying straps 31 on both sides of the template 200 in the width direction, thereby facilitating the connection between the fixing members 21 and the carrying straps 31. The fastener 21 protrudes from the support member 20 along the length of the template 200, which makes the area of ​​the fastener 21 larger than the contact area between the fastener 21 and the support member 20. The fastener 21 can also provide a connection area for the shoulder strap 31. This not only improves the connection stability between the shoulder strap 31 and the support member 20, but also improves the connection convenience between the shoulder strap 31 and the support member 20.

[0040] Combine Figure 1As shown, a side plate 10 is provided on the steel beam contact rail, and the lower end of the support member 20 is inserted and fixed to the side plate 10. Specifically, a side plate 10 is provided on the steel beam contact rail, and a groove 11 is provided on the side plate 10 near the end of the support member 20 along the length direction of the template 200. When installing the template support device 100, the lower end of the support member 20 is inserted into the groove 11 of the side plate 10 so that the lower end of the support member 20 is inserted into the side plate 10. Then, the lower end of the support member 20 is connected and fixed to the side plate 10 by bolts, thus realizing the installation of the support member 20 on the steel beam contact rail. With this arrangement, the template support device 100 can be set on the side plate 10 of the steel beam contact rail, which can reduce the impact of construction on traffic.

[0041] In this embodiment of the invention, the concrete 300 in the formwork 200 has a strength grade of C60, the ordinary reinforcing bars are made of HRB400 steel, the steel columns are made of Q345qD steel bars, and the materials used for welding include, but are not limited to, welding rods and welding wires that meet the requirements. This embodiment of the invention can be applied to the support system of bridge deck concrete formwork, which includes, but is not limited to, bridge decks of straddle-type monorail steel-concrete composite beams.

[0042] In an embodiment of this utility model, the bridge deck concrete 300 is constructed on the steel beam that has been installed and finely adjusted. The construction steps are as follows:

[0043] Step 1: After the steel beams are installed and fixed, scaffolding is erected as an operating platform, using the evacuation platform as support, to install 300mm steel bars in the bridge deck concrete.

[0044] Step Two: The support component 20 and the formwork 200 are assembled in sections at the construction site to form the formwork 200 and the formwork support device 100 as a whole. The length of each assembly stage is selected according to the lifting machinery and site conditions. The sections are connected by bolts, and sealing strips are inserted into the joints for sealing.

[0045] Step 3: On-site lifting machinery is used to lift the formwork 200 and the formwork support device 100 in sections to the top of the steel rail beam, so that the support 20 stands in the groove 11 above the contact rail of the steel beam;

[0046] Step 4: Use a level and total station to control the elevation and horizontal position of the top surface of the formwork 200. Use a straightedge to control the verticality of the formwork 200. After adjustment, temporarily fix it with a tensioner, and then install the tie rod 32. Then install the embedded parts in the bridge deck concrete 300, such as finger plates and other embedded parts.

[0047] Step 5: Use an air compressor to clean debris from inside formwork 200 and moisten formwork 200, then pour concrete 300. Pour the concrete as a whole from one end of formwork 200 to the other along its length, and strengthen the vibration of concrete 300 to ensure its compaction. Then, perform concrete curing.

[0048] In the construction steps of this utility model embodiment, the formwork support device 100 has a simple structure, is easy to install and dismantle, has good operability, and requires less high-altitude work. Using the rail-mounted beam evacuation platform to erect the operating scaffolding facilitates construction and improves construction safety and reliability.
