Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a support structure for cap beam construction and a construction method. Background Art

[0002] The cap beam is an important component that connects the upper and lower structures. Its main function is to support the superstructure of the bridge and transfer all loads to the lower structure, that is, the crossbeam of the bridge. When constructing the cap beam, it is necessary to set up a support system on the piers, then hoist the mold and tie the steel bars inside the mold, pour concrete after tying the steel bars, and complete the construction of the cap beam after the concrete solidifies.

[0003] The support structure used for cap beam construction is mainly divided into the cross-steel rod method, the corbel bracket method, the floor-standing bracket method and the clamp method. The clamp method has the advantages of no requirements for low level, flexible installation, economy and no damage to bridge piers, so it is widely used.

[0004] The existing cap beam is supported by a hoop method, and the number of hoops is usually equal to the number of piers. Therefore, the following problems are easily encountered: first, the installation and positioning between the hoops is rather complicated, because the hoops are lifted by lifting equipment and then pushed to the designated position for installation by staff. The specific height adjustment is rather complicated. The staff on the crane cannot see it and can only communicate with the high-altitude staff through walkie-talkies. Fine-tuning is rather complicated, which makes horizontal installation between multiple hoops difficult and may require multiple debugging. If the hoops are not distributed horizontally, it is easy to cause the cap beam to tilt to one side. Second, a double-hoop support system is used. The spacing adjustment between the two hoops will also cause the above-mentioned problems, which makes the support more complicated during the actual construction process. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a support structure and a construction method for cap beam construction to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a support structure for cap beam construction, comprising a pier, a first clamp and a second cross beam, a bracket is fixed to one side of the bottom of the first clamp, a guide frame is fixed to one side of the first clamp, and a guide plate is connected to the outer surface of the guide frame, and anti-detachment bolts are connected between the guide frame and the guide plate; the top of the second cross beam is connected to a base frame, and the top of the base frame is connected to a fence, a limiting piece passes through one side of the base frame, and a docking bolt passes through the other side of the base frame, and a support net is installed on the top of the base frame.

[0007] By adopting the above technical solution, the guide frame and the guide plate are conveniently assembled by the anti-slip bolts, so that the two first hoops are combined together, and the distance between the two first hoops is conveniently adjusted by the sliding of the guide frame and the guide plate to adapt to the distance between the piers, and the two first hoops can be in a horizontal state by the cooperation of the guide frame and the guide plate, without wasting too much time to align the first hoops horizontally; the second hoop is conveniently supported and positioned when the second hoop is not assembled by the setting of the bracket, so as to facilitate the assembly of the second hoop, avoid the phenomenon that the subsequent support frame cannot contact with the first beam for support due to the deviation of the installation position of the second hoop, and avoid the phenomenon that the first hoop cannot contact with the first beam for support due to the support frame being too high; the two base frames are conveniently docked by the docking bolts, and the base frame can be removed by removing the docking bolts during disassembly, and the limiter can be against the first beam, so as to limit the base frame, so that the staff can walk on the base frame, which is convenient for assembling the mold, tying the steel bars and other operations, and at the same time, the support frame is hollowed out by the setting of the support net to reduce the weight of the base frame, and the fence is used to prevent the staff from falling.

[0008] Furthermore, the longitudinal section of the bracket is in an "L" shape, and the cross section of the bracket is in an arc shape.

[0009] By adopting the above technical solution, the bracket is provided to facilitate supporting and positioning the second clamp when the second clamp is not assembled, thereby facilitating the assembly of the second clamp.

[0010] Furthermore, the guide plate is slidably connected to the guide frame, and the anti-drop bolt is slidably connected to the guide plate and the guide frame.

[0011] By adopting the above technical solution, the guide frame and the guide plate are easily assembled through the anti-drop bolts, so that the two first hoops are combined together, and the distance between the two first hoops is easily adjusted by sliding the guide frame and the guide plate to adapt to the distance between the piers.

[0012] Furthermore, two base frames are provided, and the two base frames are arranged in a mirror image.

[0013] By adopting the above technical solution, the two base frames can be conveniently butted together by the butt bolts, and the base frame can be removed by simply removing the butt bolts during disassembly.

[0014] Furthermore, the outer surface of the pier is respectively connected with a first hoop and a second hoop, and the top of the second hoop is connected with a support frame, two first beams are placed on the top of the first hoop and the support frame, and a pull rod is connected between the two first beams, and the second beam is placed on the top of the first beam.

[0015] By adopting the above technical solution, the staff places the two first beams on the top of the first clamp, and at the same time, auxiliary support is provided to the first beams through the support frame. Then the staff pulls the two first beams through the pull rod, and then the staff places the second beam on the top of the first beam to complete the construction.

[0016] Furthermore, the second hoop is in contact with the bracket, and the pier, the first hoop, the second hoop and the bracket are each provided with four.

[0017] By adopting the above technical solution, four first hoops and four second hoops are respectively assembled on the outer surfaces of the two piers, so as to facilitate the support of the two first beams, and at the same time, the four brackets facilitate the positioning of the installation positions of the four second hoops.

[0018] Furthermore, the limiting member abuts against the first cross beam, and the limiting member is threadedly connected to the base frame.

[0019] By adopting the above technical solution, the staff rotates the limiting parts so that two groups of limiting parts abut against the two sides of the two first beams respectively, and the other two groups of limiting parts abut against the outer surfaces and backs of the two first beams respectively, thereby completing the limiting.

[0020] Furthermore, there are eight limit members, two in a group, and four groups in total.

[0021] By adopting the above technical solution and increasing the number of limiting members, the contact area between the base frame and the first crossbeam is increased, thereby increasing the stability of the connection.

[0022] Furthermore, one end of the limiting member is connected to a hand wheel, and the diameter of the other end of the limiting member is greater than the diameter of one end of the limiting member.

[0023] By adopting the above technical solution and setting the handwheel, it is convenient for the staff to rotate the limit piece; the diameter of the other end of the limit piece is larger than the diameter of one end of the limit piece, and the handwheel at one end of the limit piece is cooperated to prevent the limit piece from falling off the base frame.

[0024] A method for constructing a support for cap beam construction, the specific steps of which are as follows:

[0025] Step 1: The staff fits the guide plate and the guide frame together and screws in the anti-drop bolts, so that the two first hoops are combined together. Then the staff installs the two first hoops on the two piers respectively. At this time, the two first hoops are limited by the guide frame and the guide plate, and the anti-drop bolts are used to prevent the guide frame and the guide plate from falling off, so that the two first hoops are on the same horizontal plane. Then the staff assembles the other two first hoops with bolts;

[0026] Step 2: The staff place the four second hoops on the top of the four brackets respectively, and locate the installation position of the second hoops through the brackets to avoid the deviation of the installation position of the second hoops, which causes the subsequent support frame to be unable to contact with the first beam for support, and to avoid the support frame being too high, which causes the first hoop to be unable to contact with the first beam for support. Then the staff tightens the four second hoops with bolts;

[0027] Step 3: The staff places the two first beams on the top of the first hoop, and at the same time, the first beams are auxiliary supported by the support frame. Then, the staff pulls the two first beams by the pull rod, and then the staff places the second beam on the top of the first beam;

[0028] Step 4: The staff connects the two base frames through docking bolts, and then places the base frame on the top of the second beam. The staff then rotates the limit pieces so that the two sets of limit pieces are respectively abutted against the two sides of the two first beams, and the other two sets of limit pieces are respectively abutted against the outer surface and back of the two first beams to complete the limiting. After that, the staff can walk on the base frame to facilitate operations such as assembling molds and tying steel bars. At the same time, the support net is set to make the frame hollow to reduce the weight of the base frame, and cooperate with the fence to prevent the staff from falling.

[0029] In summary, the present invention mainly has the following beneficial effects:
