TECHNICAL FIELD
[0001] The present application relates to the technical field of bent cap construction, and particularly relates to a support device for skew bent cap construction. BACKGROUND
[0002] An existing bent cap is limited by construction conditions and needs to be obliquely crossed with a bridge pier with a radially section in the shape of an oblate circle or a rectangle, and the top of the bent cap needs to be flush with the top of the bridge pier. The oblique crossing refers to that the smallest included angle between the length direction of the bent cap and the length direction of the bridge pier is an acute angle, and the bent cap is called a skew bent cap.
[0003] During the construction of the bent cap, a bent cap bracket needs to be first built on the periphery of the bridge pier. Before the bent cap bracket is built, a through hole is first preset on the pier body of the bridge pier below the skew bent cap, a through rod is then arranged in the through hole, a bracket is fixed on the through rod, a sand cylinder is then arranged on the bracket, and the bracket is then installed on the periphery of the bridge pier by taking the sand cylinder as a temporary support. After the bracket is installed, a formwork is built on the bracket as a construction platform and a support platform, and then concrete can be poured into the formwork. After the concrete is solidified and shaped, the skew bent cap is formed.
[0004] After the skew bent cap is constructed, the bracket also needs to be unloaded by using the sand cylinder for convenient turnover. The sand cylinder unloading method needs to unload sand from the sand cylinder for multiple times to lower the bracket, so that the bracket is separated from the bent cap, and then the bracket can be unloaded as a whole. Therefore, the sand cylinder unloading method is not convenient to operate. In addition, since the skew bent cap is obliquely crossed with the bridge pier and the top of the skew bent cap is flush with the top of the bridge pier, the skew bent cap also causes visual obstruction to the unloading of sand from the multiple sand cylinders on both sides of the bracket, so that the unloading process of the sand cylinder is difficult to control, further increasing the difficulty of unloading the bracket and reducing the unloading efficiency of the bracket.

Before the diagonal cover beam, which is flush with the top of the bridge pier and is distributed in an oblique and intersecting manner with the bridge pier, is constructed, a preset through hole is first arranged at a position of the bridge pier which is lower than the diagonal cover beam, then the first support of the support device for diagonal cover beam construction is arranged in the preset through hole, then the first support is hinged to the second support, then the first diagonal cable is fixed between the first support and the top of the bridge pier, and then the second diagonal cable is fixed between the second support and the top of the bridge pier; at this time, the first diagonal cable, the second diagonal cable and the first support and the second support which are hinged to each other can form a stable triangular support system, so that the first support and the second support are stably arranged on the side of the bridge pier and can be used as a construction support platform to support the diagonal cover beam during construction.

DETAILED DESCRIPTION
[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0039] Example:
[0040] like Figures 1-4 As shown, the support device for the construction of the skew cap beam provided in this embodiment includes a first support 1, a second support 2, a first stay cable 3, and a second stay cable 4; the first support 1 is inserted into a pre-set hole in the pier body of the pier 6 below the skew cap beam 5, and one side of the first support 1 is hinged to one side of the second support 2; the first stay cable 3 is connected between the first support 1 and the top of the pier 6, and the second stay cable 4 is connected between the second support 2 and the top of the pier 6.
[0041] Before constructing the skew cap beam 5, which is level with the top of pier 6 and inclined to intersect with pier 6, pre-drill holes can be made at a position on pier 6 lower than the skew cap beam 5. Then, the first support 1 of the skew cap beam construction support device is inserted into the pre-drill holes. The first support 1 and the second support 2 are then hinged together. The first stay cable 3 is fixed between the first support 1 and the top of pier 6, and the second stay cable 4 is fixed between the second support 2 and the top of pier 6. At this time, the first stay cable 3, the second stay cable 4, and the hinged first support 1 and second support 2 can form a stable triangular support system, so that the first support 1 and the second support 2 are stably located on the periphery of pier 6 and can serve as a construction support platform to support the construction process of the skew cap beam 5.
[0042] To further ensure the stability of the first support 1 and the second support 2, the hinge between the first support 1 and the second support 2 can be pushed into the pre-set through hole of the pier 6. At this time, the pre-set through hole can be used to limit the hinge between the first support 1 and the second support 2 to prevent the first support 1 and the second support 2 from rotating freely.
[0043] Alternatively, in order to ensure the stability of the first support 1 and the second support 2, a plurality of pin shafts and bolts can be arranged at the hinge between the first support 1 and the second support 2, the pin shafts are used to cement the first support 1 and the second support 2, and the bolts are used to further connect the first support 1 and the second support 2 to prevent the first support 1 and the second support 2 from rotating freely after being hinged.
[0044] When the skew cap beam 5 is constructed, in order to recycle the skew cap beam construction support device, the skew cap beam construction support device needs to be separated from the constructed skew cap beam 5, so as to unload the skew cap beam construction support device. During the unloading process, the first cable 3 and the second cable 4 can be loosened first, then the hinge between the first support 1 and the second support 2 is pushed out from the preset hole of the pier 6, then the hinge is separated, and the first support 1 or the second support 2 is pulled out from the preset hole of the pier 6, so that the first support 1 and the second support 2 are separated, and then the first support 1 and the second support 2 are separated from the skew cap beam 5, and then the first cable 3 and the second cable 4 are separated from the top of the pier 6, so as to complete the unloading of the skew cap beam construction support device.
[0045] Since only the hinge between the first support 1 and the second support 2 needs to be separated and the first support 1 or the second support 2 needs to be pulled out from the preset hole of the pier 6 during the unloading process, the first support 1 and the skew cap beam 5 are separated, and the second support 2 and the skew cap beam 5 are separated, so the unloading process of the skew cap beam construction support device does not need to use a sand cylinder, does not need to unload sand from the sand cylinder multiple times, and does not need to observe the sand cylinder unloading process, so it will not be hindered by the line of sight of the skew cap beam 5. The unloading process of the skew cap beam construction support device is more convenient than the sand cylinder unloading method, has lower difficulty, and has higher unloading efficiency.
[0046] Compared with the prior art, the support device for skew cap beam construction provided by the embodiment can form a stable triangular support system on the side of the pier 6 by arranging the first support 1 and the second support 2 in the preformed hole of the pier 6, connecting the first stay cable 3 between the first support 1 and the top of the pier 6, and connecting the second stay cable 4 between the second support 2 and the top of the pier 6, so that a stable bracket structure can be formed on the side of the pier 6, and the skew cap beam 5 can be stably supported during construction. When the support device for skew cap beam construction is removed, the first support 1 and the second support 2 can be separated at the hinge, and the first support 1 or the second support 2 can be pulled out of the hole of the pier 6, so that the support device can be separated from the skew cap beam 5, and then the first stay cable 3 and the second stay cable 4 can be separated from the top of the pier 6 to facilitate the removal of the entire device. Therefore, the removal process of the support device for skew cap beam construction does not need to use a sand cylinder, and the operation is more convenient and the removal difficulty is lower.
[0047] It should be further pointed out that the first support 1 and the second support 2 in the support device for skew cap beam construction are used as brackets for the construction of the skew cap beam 5. Compared with the prior art, the support device for skew cap beam construction only needs to preform a hole in the pier 6, does not need to fix a cross pin on the cross pin, and does not need to use a sand cylinder, so that the support device for skew cap beam construction can effectively simplify the bracket construction process steps, improve the construction efficiency, and reduce the use of materials and save construction costs.
[0048] In actual application, the first stay cable 3 and the second stay cable 4 can be fixedly connected to the top of the pier 6 by pre-buried fixing, and when the support device for skew cap beam construction is removed, the first stay cable 3 and the pier 6 need to be separated by cutting, and the second stay cable 4 and the pier 6 need to be separated by cutting.
[0049] In order to improve the construction convenience, as shown in Figure 2 and Figure 3 , the support device for skew cap beam construction of the embodiment preferably further comprises a fixing structure 7 fixed to the top of the pier 6, and the first stay cable 3 and the second stay cable 4 are connected to the fixing structure 7.
[0050] The fixing structure 7 can be fixed to the top of the pier 6 by pre-buried fixing, and after the first stay cable 3 and the second stay cable 4 are connected to the fixing structure 7, the first stay cable 3 and the second stay cable 4 can be fixedly connected to the top of the pier 6.
[0051] It should be noted that, in order to improve the stability of the first and second stay cables 3 and 4, the support device for the skew cap beam construction provided in the embodiment is applied to the construction process of the skew cap beam 5, and therefore the top of the fixing structure 7 is preferably arranged at a smaller distance from the top of the pier 6, specifically, 1-10 cm.
[0052] Since the columnar or rod-shaped structure is higher than the plate-shaped or block-shaped structure, the support stability is poorer, and the columnar or rod-shaped structure has a smaller contact area with the top of the pier 6, the fixing structure 7 in the embodiment is preferably a plate-shaped or block-shaped structure.
[0053] Further, as shown in Figure 2 and Figure 3 , the fixing structure 7 includes a fixing base 70, a first fixing block 71 and a second fixing block 72; the fixing base 70 is fixed to the top of the pier 6, and the first and second fixing blocks 71 and 72 are fixed to the fixing base 70 at intervals, the first stay cable 3 is fixedly connected to the first fixing block 71, and the second stay cable 4 is fixedly connected to the second fixing block 72.
[0054] Among them, the fixing base 70 can be formed by two parallel strip-shaped structures, at this time, the first and second fixing blocks 71 and 72 can be fixed between the two strip-shaped structures respectively.
[0055] Specifically, the fixing base 70 can be formed by two parallel I-shaped steel or other section steels, and the first and second fixing blocks 71 and 72 can be clamps respectively. The clamps are used to clamp the first and second stay cables 3 and 4, and can also relax the first and second stay cables 3 and 4.
[0056] In the embodiment, the first stay cable 3 and the first support 1 can also be connected by a clamp fixed to the side of the first support 1 facing away from the skew cap beam 5, and the first stay cable 3 is connected to the clamp after passing through the first support 1.
[0057] Correspondingly, the second stay cable 4 and the second support 2 can also be connected by a clamp fixed to the side of the second support 2 facing away from the skew cap beam 5, and the second stay cable 4 is connected to the clamp after passing through the second support 2.
[0058] Further, the first fixing block 71 is provided with a first through hole, the first stay cable 3 is fixed in the first through hole, and the first through hole extends along the length direction of the first stay cable 3; the second fixing block 72 is provided with a second through hole, the second stay cable 4 is fixed in the second through hole, and the second through hole extends along the length direction of the second stay cable 4.
[0059] When the first fixing block 71 and the second fixing block 72 are both clamps, in order to clamp the first cable 3 and the second cable 4, the first fixing block 71 and the second fixing block 72 are respectively provided with a first through hole and a second through hole. In use, the end of the first cable 3 close to the first fixing block 71 is inserted into the first through hole and extends to the side of the first fixing block 71 close to the second fixing block 72, and the first fixing block 71 can clamp and fix the first cable 3 in the first through hole. Correspondingly, the end of the second cable 4 close to the second fixing block 72 is inserted into the second through hole and extends to the side of the second fixing block 72 close to the first fixing block 71, and the second fixing block 72 can clamp and fix the second cable 4 in the second through hole.
[0060] The first through hole extends along the length direction of the first cable 3, so that the first cable 3 can be straightened in a straight line without being bent at the first fixing block 71, which not only facilitates the clamping and fixing of the first cable 3 by the first fixing member, but also effectively improves the tension stability of the first cable 3 on the first support beam 10.
[0061] Correspondingly, the second through hole extends along the length direction of the second cable 4, so that the second cable 4 can be straightened in a straight line without being bent at the second fixing block 72, which not only facilitates the clamping and fixing of the second cable 4 by the second fixing member, but also effectively improves the tension stability of the second cable 4 on the second support beam 20.
[0062] Further, the fixing structure 7 further comprises a pre-embedded part, which is pre-embedded and fixed on the top of the pier 6, and the fixing seat 70 is fixedly connected with the pre-embedded part.
[0063] In actual application, the fixing seat 70 of the fixing structure 7 can be directly pre-embedded and fixed on the top of the pier 6 to realize the fixed connection between the fixing structure 7 and the top of the pier 6.
[0064] However, in order to recycle the fixing seat 70, the first fixing block 71 and the second fixing block 72 on the fixing structure 7 to save materials and ensure the neatness of the top of the pier 6, the fixing structure 7 of the embodiment preferably further comprises a pre-embedded part, and the pre-embedded part can be a fastener such as a bolt.
[0065] The fastener such as a bolt can realize the detachable connection between the fixing seat 70 and the top of the pier 6, and can ensure the connection stability of the fixing seat 70 and the top of the pier 6.
[0066] As Figures 2-4As shown, there are multiple first stay cables 3 and multiple second stay cables 4. The multiple first stay cables 3 are divided into two groups, and the multiple second stay cables 4 are divided into two groups. The first support 1 has two connection points that are spaced apart along its length direction, and the two groups of first stay cables 3 are respectively connected to the two connection points of the first support 1. The second support 2 has two connection points that are spaced apart along its length direction, and the two groups of second stay cables 4 are respectively connected to the two connection points of the second support 2.
[0067] When multiple first stay cables 3 are connected to two connection points on the first support 1 that are spaced apart along its length, the multiple first stay cables 3 can effectively improve the structural stability and balance of the first support 1 along its length, thereby further improving the support stability of the skew cap beam construction support device for the construction process of the skew cap beam 5.
[0068] Correspondingly, when multiple second stay cables 4 are connected to two connection points on the second support 2 that are spaced apart along its length, the multiple second stay cables 4 can effectively improve the structural stability and balance of the second support 2 along its length, thereby further improving the support stability of the skew cap beam construction support device for the construction process of the skew cap beam 5.
[0069] Each set of first stay cables 3 may include multiple first stay cables 3, which are distributed in parallel or intertwined to form a set of first stay cables 3. Correspondingly, each set of second stay cables 4 may include multiple second stay cables 4, which are distributed in parallel or intertwined to form a set of second stay cables 4.
[0070] In practical applications, both the first cable 3 and the second cable 4 can be made of tensile materials such as steel wire rope and steel strand.
[0071] like Figures 2-4 As shown, the first support 1 includes a plurality of first support beams 10 arranged in parallel, and the second support 2 includes a plurality of second support beams 20 arranged in parallel. The plurality of first support beams 10 are respectively inserted into a plurality of pre-set holes in the pier body of the pier 6 below the skew cap beam 5, and the plurality of first support beams 10 and the plurality of second support beams 20 are respectively hinged. The first support 1 also includes a first connecting beam 11, and a first connecting beam 11 is connected between any two adjacent first support beams 10. The second support 2 also includes a second connecting beam 21, and a second connecting beam 21 is connected between any two adjacent second support beams 20.
[0072] In the embodiment, the first support 1 and the second support 2 can have the same structure and be symmetrically distributed with the center axis of the radial section of the pier 6 as the axis of symmetry, so that the installation convenience of the first support 1 and the second support 2 can be improved and the unloading balance of the first support 1 and the second support 2 can be ensured during unloading.
[0073] When the first support 1 is composed of a plurality of first support beams 10 distributed in parallel, the size requirement of the plurality of first support beams 10 for the pre-designed hole in the pier 6 is smaller than that of the frame structure, and the damage to the pier 6 is also smaller, so that the pier 6 can be used to stably support the first support 1. Correspondingly, when the second support 2 is composed of a plurality of second support beams 20 distributed in parallel, the size requirement of the plurality of second support beams 20 for the pre-designed hole in the pier 6 is smaller than that of the frame structure, and the damage to the pier 6 is also smaller, so that the pier 6 can be used to stably support the second support 2.
[0074] To further reduce the damage of the first support 1 and the second support 2 to the pier 6, the first support beam 10 and the second support beam 20 are preferably two in the embodiment.
[0075] In addition, the first support beam 10 can also serve as the main beam of the first support 1 to support the first connecting beam 11, and the first connecting beam 11 is used to connect a plurality of first support beams 10 distributed in parallel to improve the overall structural stability of the first support 1.
[0076] Correspondingly, the second support beam 20 can also serve as the main beam of the second support 2 to support the second connecting beam 21, and the second connecting beam 21 is used to connect a plurality of second support beams 20 distributed in parallel to improve the overall structural stability of the second support 2.
[0077] In the embodiment, the first connecting beam 11 can be fixed between two adjacent first support beams 10 by welding or bolt connection, and the second connecting beam 21 can be fixed between two adjacent second support beams 20 by welding or bolt connection.
[0078] In the embodiment, to realize the articulation between the first support beam 10 and the second support beam 20, the first support beam 10 can be made of two parallel strip beams, and the beams of the two strip beams are provided with corresponding through holes.
