Description

Technical Field

[0001] This utility model relates to the field of cap beam construction technology. More specifically, this utility model relates to an adjustable tensioning platform for cap beams. Background Technology

[0002] Suspended tensioning platforms have been widely used in prestressed tensioning construction of various types of cap beams. However, traditional tensioning platforms are generally only suitable for a single type of cap beam, mainly applicable to structures with blocks at both ends of ordinary cap beams. They are supported on top of the blocks by corbels, and then a ring of structural members is installed to hold the blocks horizontally on the outside. They cannot be used when the cap beam structure has a back wall or back wall heights. In addition, existing tensioning platforms are relatively fixed in use during on-site construction and cannot be flexibly adjusted. As a result, for each cap beam with a different shape, a new tensioning platform needs to be welded and fabricated. The reuse rate of tensioning platforms is low. Furthermore, since most tensioning platforms lack anchor points, the anchoring of the platform on the cap beam is also a common problem encountered in prestressed tensioning construction, resulting in insufficient structural stability and affecting the safety and stability of the tensioning construction. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable tensioning platform for cap beams, so as to solve the technical problem that existing cap beam tensioning platforms are difficult to apply to different cap beam forms.

[0004] To achieve these objectives and other advantages according to this utility model, an adjustable tensioning platform for cap beams is provided, comprising:

[0005] The platform frame is used to fit and install on the transverse side of the cap beam. The width of the platform frame is not greater than the longitudinal dimension of the cap beam. The platform frame is used as a platform for tensioning construction. On the side of the platform frame facing the cap beam, there are symmetrical installation parts in the longitudinal direction. The installation parts are provided with first bolt holes at vertical intervals.

[0006] The top connector includes an embedded part at the bottom of the cap beam back wall, and the top of the embedded part is connected to the top of the platform frame by fasteners.

[0007] The support brackets are arranged in pairs on one side of the mounting plate and below the top connector. The bottom of the support brackets is horizontally set to support the top surface of the main body of the cap beam or the top surface of the cap beam's stop block. One side of the support bracket is vertically set and has a second bolt hole for bolt connection with the corresponding first bolt hole. The paired support brackets are used to clamp the back wall on the front and rear sides in the longitudinal direction of the bridge.

[0008] Preferably, a first connecting hole is drilled on the top side of the platform frame facing the cap beam. The embedded part is a tapered nut pre-embedded on the top of the back wall. Multiple tapered nuts are provided. All tapered nuts have a common steel toothed shank on their top. The lower end of the steel toothed shank has a screw hole drilled downwards. The connection is fixed by screwing a bolt into the screw hole and between the steel toothed shank and the tapered nut. The fastener includes a precision-rolled threaded steel bar and a fastening nut. A second connecting hole is drilled on the steel toothed shank along the transverse direction. A precision-rolled threaded steel bar is inserted into both the first and second connecting holes. A fastening nut is screwed onto the outside of the first or second connecting hole corresponding to the precision-rolled threaded steel bar for fastening.

[0009] Preferably, the platform frame includes a vertically arranged cuboid outer frame, with a base plate fixed to the bottom of the inner side of the outer frame. The side of the outer frame away from the cap beam is the outer side. The left and right sides of the outer frame facing the cap beam are the left and right sides, respectively. A first horizontal bar is connected vertically at intervals on the outer side. A vertical bar is connected to the middle of the left and right sides, and a second horizontal bar is connected vertically at intervals on the side of the left and right sides away from the cap beam. A third horizontal bar is connected vertically at intervals on the side of the vertical bar close to the cap beam. A passage window is formed in the space between the second or third horizontal bars.

[0010] Preferably, the top of the outer frame is connected with reinforcing rods extending transversely along the longitudinal bridge direction, and the top of the reinforcing rods are connected together with a top rod along the longitudinal bridge direction.

[0011] Preferably, the support bracket is formed by welding multiple rods sequentially along the direction of a right triangle, wherein a bolt washer is installed on the outer side of the vertical side of the support bracket, and the hole on the bolt washer is coaxially arranged with the second bolt hole.

[0012] Preferably, the second bolt holes are symmetrically arranged at the upper and lower ends of the vertical side of the support bracket, and the bolt pads are respectively arranged at the upper and lower ends of the vertical side.

[0013] This utility model has at least the following beneficial effects: The adjustable tensioning platform for cap beams of this utility model includes a platform frame, a top connector, and support brackets. It combines the structural form of the tensioning platform with the form of the cap beam on site, making it a structure of top tension and bottom support. The top connector is tensioned and prevents overturning, while the bottom support is supported on the cap beam block by the support brackets. Since the structural dimensions of each cap beam are different, in order to adjust the support position of the support brackets to adapt to the height of the block, the support brackets of the tensioning platform are made into a detachable structure. The support brackets are connected to the platform frame by bolts. When using different cap beams, the support brackets can be adjusted up / down according to the structural dimensions of the cap beam and connected to the first bolt hole at the corresponding position, thereby meeting the tensioning construction of the cap beam. This makes the adjustable tensioning platform for cap beams widely applicable and suitable for various cap beam tensioning constructions. It solves the problem that the tensioning platform cannot be rooted during cap beam tensioning, and provides stable support at the end of the cap beam and is easy to disassemble.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-5 As shown, the adjustable tensioning platform for the cap beam of this utility model includes:

[0024] Platform frame 1 is used to fit and install on the transverse side of cap beam 11. The width of platform frame 1 is not greater than the longitudinal dimension of cap beam 11. Platform frame 1 is used as a platform for tensioning construction. On the side of platform frame 1 facing cap beam 11, there are symmetrical installation parts in the longitudinal direction. The installation parts are provided with first bolt holes at vertical intervals.

[0025] The top connector 2 includes an embedded part 4 whose lower end is embedded in the top of the back wall 12 of the cap beam 11, and the upper end of the embedded part 4 is connected to the top of the platform frame 1 by a fastener 5.

[0026] The support brackets 3 are arranged in pairs on one side of the mounting plate and below the top connector 2. The bottom of the support brackets 3 is horizontally arranged to support the top surface of the main body of the cap beam 11 or the top surface of the block of the cap beam 11. One side of the support brackets 3 is vertically arranged and has a second bolt hole, which is used to connect with the first bolt hole at the corresponding position by bolts. The pair of support brackets 3 are used to clamp the back wall 12 on the front and rear sides in the longitudinal direction of the bridge.

[0027] Platform frame 1 serves as the working platform for construction personnel. The tensioning position of cap beam 11 is aligned within platform frame 1. Connecting crossbars are arranged on the outside of platform frame 1 for basic protection. The top of platform frame 1 is connected to the top of back wall 12 via embedded parts 4 through means such as tie rods or precision-rolled threaded steel bars, so that platform frame 1 is tightly attached to the end of cap beam 11 in the horizontal direction. A pair of support brackets 3 are set in the middle of platform frame 1. On one hand, the bottom of the support brackets 3 is supported on the top surface of cap beam 11, which is lower than the top of back wall 12. On the other hand, the spacing of the pair of support brackets 3 is set according to the thickness of back wall 12, so that the support brackets 3 are abutted against the two sides of back wall 12, which plays a role in longitudinal bridge limiting and stabilizing. The top connector 2 provides a part of the upward tension, mainly through the support brackets 3, to achieve the fastening and stable installation of the tensioning platform at cap beam 11.

[0028] The tensioning platform's structure is combined with the on-site cap beam 11 to create an upper-pull, lower-support structure. The upper pull top connector 2 bears the force and prevents overturning, while the lower support is supported on the cap beam 11 block by the support bracket 3. Since the structural dimensions of each cap beam 11 are inconsistent, the support bracket 3 of the tensioning platform is made into a detachable structure to adjust the support position of the support bracket 3 to adapt to the height of the block. The support bracket 3 is bolted to the platform frame 1. When using different cap beams 11, the support bracket 3 can be adjusted up / down according to the structural dimensions of the cap beam 11 and connected to the first bolt hole at the corresponding position, thereby meeting the tensioning construction of the cap beam 11. This makes the adjustable tensioning platform of the cap beam 11 widely applicable, suitable for various cap beam 11 tensioning constructions, solving the problem of the tensioning platform not being able to take root during cap beam 11 tensioning, and providing stable support at the end of the cap beam 11 and easy disassembly.

[0029] In another technical solution, such as Figure 1 As shown, a first connecting hole 13 is drilled on the top of the platform frame 1 on the side facing the cap beam 11. The embedded part 4 is a tapered nut pre-embedded on the top of the back wall 12. Multiple tapered nuts are provided. All tapered nuts have a steel toothed sill at their top. The lower end of the steel toothed sill has a screw hole drilled downwards. The fastener 5 includes a precision-rolled threaded steel bar and a fastening nut. A second connecting hole is drilled on the steel toothed sill along the transverse direction. A precision-rolled threaded steel bar is inserted into both the first connecting hole 13 and the second connecting hole. A fastening nut is screwed on the outside of the first connecting hole 13 or the second connecting hole corresponding to the precision-rolled threaded steel bar for fastening.

[0030] The bottom of the steel toothed sill is provided with a screw hole corresponding to a conical nut. A bolt is installed between the screw hole and the conical nut for fixing. Then, a precision-rolled threaded steel bar is installed to provide tension to the top of the platform frame 1, so that the platform frame 1 is tightly attached to the side of the end of the cap beam 11 and does not shake.

[0031] In another technical solution, such as Figures 1-5 As shown, the platform frame 1 includes a vertically arranged cuboid outer frame 6. A base plate is fixed to the bottom of the inner side of the outer frame 6. The side of the outer frame 6 away from the cap beam 11 is the outer side. The left and right sides of the outer frame 6 facing the cap beam 11 are the left side and the right side, respectively. The outer side is connected with first horizontal bars 7 at intervals along the vertical direction. Vertical bars are connected to the middle of the left and right sides, respectively. The left and right sides are connected with second horizontal bars 8 at intervals along the vertical direction on the side of the vertical bars away from the cap beam 11. The vertical bars 9 are connected with third horizontal bars 9 at intervals along the vertical direction on the side of the vertical bars close to the cap beam 11. The space between the second horizontal bars 8 or the third horizontal bars 9 forms a passage window.

[0032] The outer frame 6 has no connectors on the side facing the cap beam 11. On the other sides, it is connected to the corresponding first crossbar 7, second crossbar 8, and third crossbar 9 for protection. The first crossbar 7 and second crossbar 8 can have the same spacing and material, while the third crossbar 9 has a larger spacing, forming a safe passage window or facilitating the connection of materials and small equipment during construction. The platform frame 1 can be manufactured according to the following specifications: the outer frame 6 is approximately 4 meters high, 2 meters long in the transverse direction, and 2.4 meters long in the longitudinal direction, using No. 14 I-beams; the second crossbar 8 and third crossbar 9 use φ50X12mm steel pipes; and the support brackets 3 are 50cm-100cm long and 50cm-100cm high.

[0033] In another technical solution, such as Figure 5 As shown, the top of the outer frame 6 is connected with reinforcing rods extending transversely along the longitudinal direction of the bridge. The tops of the reinforcing rods are connected to a top rod 10 along the longitudinal direction of the bridge. By setting the top rod 10 and the reinforcing rods, the rigidity of the platform frame 1 structure is improved. On the other hand, when the platform frame 1 is lifted as a whole, the lifting hook of the crane can be hooked onto the top rod 10 or the rope can be wrapped around the top rod 10, which facilitates operation.

[0034] In another technical solution, such as Figures 1-3 As shown in Figure 5, the support bracket 3 is formed by welding multiple rods sequentially along the direction of a right triangle. A bolt washer is installed on the outer side of the vertical side of the support bracket 3, and the hole on the bolt washer is coaxially arranged with the second bolt hole.

[0035] The bottom of the support bracket 3 is flat to facilitate support on the corresponding surface of the cap beam 11 structure. For the cap beam 11 with a back wall 12 structure, a pair of support brackets 3 are symmetrically connected to the side of the platform frame 1 facing the cap beam 11 according to the thickness of the back wall 12. The spacing between the pair of support brackets 3 is equal to the thickness of the back wall 12. The overall tensioning platform is limited in the thickness direction of the back wall 12 through the opposite surfaces of the pair of support brackets 3. The support brackets 3 and the platform frame 1 are connected by bolts, which can be reused. The installation position of the support brackets 3 can be flexibly adjusted according to the vertical spacing of the second bolt holes, which can adapt to various back wall 12 heights and cooperate with the top connector 2.

[0036] In another technical solution, such as Figures 1-3 As shown in Figure 5, the second bolt holes are symmetrically arranged at the upper and lower ends of the vertical side of the support bracket 3, and bolt washers are respectively arranged at the upper and lower ends of the vertical side. Bolt washers are provided at the second bolt holes on both the upper and lower sides to improve the tightness of the bolt installation connection and the supporting capacity of the support bracket 3 for the platform frame 1.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
