Description

Technical Field

[0001] The utility model belongs to the technical field of bridge slab hinge reinforcement installation and positioning equipment, and specifically relates to a hinge reinforcement positioning device. Background Art

[0002] In bridge deck production, the function of hinged joint reinforcement is to connect the top, bottom and side panels, so that the assembled panels can bear the load together. The cracking and voiding of hinged joints will affect the safety and durability of the bridge, and pose a great safety hazard.

[0003] In order to ensure the dimensional accuracy of the steel cages in each panel, the top and bottom plate steel cages are processed on two different steel placenta racks. The template assembly process is to place the bottom plate steel cage first, then install the inner mold and top plate steel bars in sequence, and finally install the hinged seam bars for connection. According to the design drawings, the hinged seam bars need to pass through the top plate steel bars and be tied and connected with the bottom plate steel cage. Because the top and bottom plates are processed separately with two different molds, the hinged seam bars cannot be installed on the placenta rack in advance at the same time.

[0004] At present, the hinged joint reinforcement in the prefabricated hollow slab reinforcement cage is installed by manual wire tying. Due to the long span of the bridge slab, the number of twisted joint reinforcements is very large, and workers need to tie them one by one, which consumes a lot of manpower and material resources, and the construction speed is slow and the construction accuracy is low. In addition, the most important thing is that when pouring concrete or vibrating, the wire tying place is easily broken and loosened due to the influence of external forces, which affects the straightness, height and connection firmness of the hinged joint reinforcement installation, resulting in uneven positions, skewed deformation (such as Fig.12 As shown in the figure), manual secondary adjustment is required, and the finishing process is affected by the solidification of concrete and is very inconvenient.

[0005] Therefore, in order to improve the installation quality of the hinged reinforcement, after combining the bridge deck design, it was decided to develop a hinged reinforcement positioning and installation equipment that can be installed on the side formwork to change the current problems of inconvenient manual trimming, inconsistent standards and unreliable installation quality. Utility Model Content

[0006] The utility model aims to solve the technical problems in the prior art that hinged seam bars are prone to deflection and deformation, are inconvenient to manually trim, have inconsistent standards and unreliable installation quality, and provide a hinged seam bar positioning device to overcome the deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a hinged reinforcement positioning device, comprising:

[0008] A supporting component, which is arranged correspondingly at the installation position of the hinged seam reinforcement on the template;

[0009] as well as,

[0010] A plurality of positioning members are connected to the supporting member and used for connecting hinged seam bars.

[0011] Preferably, the positioning member is sleeved on the supporting member via a sliding member and slides along the axial direction of the supporting member.

[0012] Preferably, the sliding member is fastened to the supporting component via a fastening mechanism.

[0013] Preferably, the fastening mechanism comprises an internal threaded hole opened on the sliding member toward the supporting component, and a bolt threadedly connected to the internal threaded hole and contacting the supporting component.

[0014] Preferably, the fastening mechanism comprises a plurality of positioning holes 1 uniformly arranged on the supporting component and a positioning hole 2 arranged on the positioning member, and the positioning hole 1 and the positioning hole 2 are connected by a pin shaft.

[0015] Preferably, it also includes a mounting mechanism for connecting to the formwork support.

[0016] Preferably, the mounting mechanism comprises a fixing rod and a fixing tube, one end of the fixing rod is fixedly connected to the supporting component, and the other end is plugged into one end of the fixing tube, and the other end of the fixing tube is threadedly connected to a screw provided on the template via an internal thread.

[0017] Preferably, the support component is provided with scale lines.

[0018] Preferably, the supporting component is a square tube, a round tube, an angle steel or a long rod.

[0019] Preferably, the positioning member is a hanging rod or a hook.

[0020] Due to the adoption of the above technical solution, the utility model can produce the following technical effects:

[0021] First, the installation standards and quality of the hinged reinforcement are reliably guaranteed.

[0022] The hinged reinforcement is fixed by the traditional binding method, which is improved to the current binding and supporting method. When pouring concrete and vibrating, the hinged reinforcement will be subjected to greater external force. The positioning parts can ensure that the hinged reinforcement is always in the predetermined position. Even if the binding becomes loose, the position of the hinged reinforcement can still be guaranteed to remain unchanged. After the concrete is formed, the position of each hinged reinforcement is unified and orderly, which ensures the firmness of the connection between the formworks, and the quality and safety of the project are fully guaranteed.

[0023] Second, it saves considerable costs and shortens the construction period.

[0024] In the past, the hinged bars were manually trimmed one by one after the concrete was formed. Due to the influence of concrete solidification, the position of the hinged bars was fixed, and the hinged bars needed to be bent and trimmed, which was very inconvenient. In addition, the direction and angle of the hinged bars were random, and the trimming consumed a lot of manpower and time. The effect after trimming was also very limited, which affected the splicing effect of adjacent prefabricated bridge panels and consumed a lot of unnecessary time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following will be combined Figures 1 to 11 The technical solution of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0046] Please refer to Figures 1 to 11 The utility model provides a hinged rib positioning device, comprising a support component 100, which is arranged at the installation position of the hinged rib 3 on the template 6. The support component 100 is a long strip structure, usually made of square tube, round tube, angle steel or long rod, and its axial direction is consistent with the placement direction of the hinged rib 3.

[0047] refer to Figure 1 In practice, the support member 100 is placed on one side of the hinge ribs and outside the template 6. The hinge ribs 3 are arranged in the same straight line direction and are located on one side of the support member 100.

[0048] A plurality of positioning members 200 (specifically, hooks 201 or hanging rods 202) are provided on the support member 100, which are connected to the support member 100 (for example, fixed by welding) and used to connect the hinge ribs 3. The axial direction of the positioning members 200 corresponds to the axial direction of the support member 100 in a crisscross pattern, and the axial direction of the positioning members 200 is arranged toward the hinge ribs, and the hinge ribs can be directly placed on the positioning members 200 to achieve a supported and lifted posture.

[0049] The hook 201 has a better limiting effect, and the hinged bar is not easy to be unhooked, but it is inconvenient to disassemble, and the hinged bar can be separated after the entire disassembly. The hanging rod 202 has no bending part and is easier to disassemble, but it is easy to cause the hinged bar to be skewed at a certain angle when the concrete is vibrated, so each has advantages and disadvantages.

[0050] Of course, more than one hinge rib may be arranged side by side on each positioning member 200. When the number of hinge ribs increases, there are more connection points between the panels and the connection is more secure.

[0051] This method can facilitate the placement, positioning and binding of hinged bars. The main thing is that after the hinged bars are tied, when pouring and vibrating concrete, it can provide a good limiting support effect for the hinged bars to prevent the hinged bars from being skewed due to external interference. Even if the hinged bars are loose at the binding, the posture of the hinged bars can be guaranteed, and finally each hinged bar on the prefabricated bridge deck is evenly and evenly aligned, so there is no need for workers to manually trim it. At the same time, it can also improve the connection firmness of adjacent panels and ensure the quality of construction.

[0052] Due to the adoption of the above technical solution, the utility model can produce the following technical effects:

[0053] First, the installation standards and quality of the hinged reinforcement are reliably guaranteed.

[0054] The hinged reinforcement is fixed by the traditional binding method, which is improved to the current binding and supporting method. When pouring concrete and vibrating, the hinged reinforcement will be subjected to greater external force. The positioning parts can ensure that the hinged reinforcement is always in the predetermined position. Even if the binding becomes loose, the position of the hinged reinforcement can still be guaranteed to remain unchanged. After the concrete is formed, the position of each hinged reinforcement is unified and orderly, which ensures the firmness of the connection between the formworks, and the quality and safety of the project are fully guaranteed.

[0055] Second, it saves considerable costs and shortens the construction period.

[0056] In the past, the hinged bars were manually trimmed one by one after the concrete was formed. Due to the influence of concrete solidification, the position of the hinged bars was fixed, and the hinged bars needed to be bent and trimmed, which was very inconvenient. In addition, the direction and angle of the hinged bars were random, and the trimming consumed a lot of manpower and time. The effect after trimming was also very limited, which affected the splicing effect of adjacent prefabricated bridge panels and consumed a lot of unnecessary time. Example

[0057] Reference Figures 6 to 11 This embodiment is to achieve the position change of the positioning member 200, so as to adjust the spacing between the hinged seam reinforcements and meet the requirements of different construction sizes.

[0058] In this embodiment, in order to adjust the spacing between the positioning members 200 to accommodate different placement distances of the hinged ribs, the positioning members 200 can also slide in the axial direction of the support member 100. The distance or size of the sliding movement can be quickly determined by observing the scale lines 102 on the support member 100.

[0059] Specifically, the positioning member 200 is sleeved on the support member 100 through the sliding member 701 and slides along the axial direction of the support member 100. The sliding member 701 is a sleeve member that matches the support member 100. The relative position between the positioning members 200 is changed by sliding in the axial direction of the support member 100, thereby adapting to the different placement requirements of the hinged seam ribs. In this way, the spacing of each hinged seam rib can be changed instead of being fixed. The sliding member 701 is fastened to the support member 100 through a fastening mechanism to achieve a positioning effect and prevent the hinged seam ribs from deviating under the influence of external forces.

[0060] refer to Figure 6 , Figures 9 to 11 As a further improvement, the fastening mechanism includes an internal threaded hole 703 opened on the sliding member 701 toward the supporting component 100, which penetrates the wall thickness direction of the sliding member 701, and a bolt 702 threadedly connected to the internal threaded hole 703 and contacts the supporting component 100.

[0061] When the bolt 702 is tightened, it can touch the side of the support component 100 to achieve a tightening and fixing effect, the sliding member 701 cannot move, and the positioning member 200 can firmly support the hinge rib 3. On the contrary, when the bolt 702 is loosened, the sliding member 701 can slide freely in the axial direction of the support component 100. This structure can realize the fixing of the positioning member 200 at any position, that is, the installation position of the hinge rib can be adjusted arbitrarily. However, it is necessary to take protective measures for the thread joint to prevent debris from entering and affecting the normal tightening or loosening.

[0062] refer to Figure 7 and Figure 8 As a further improvement, the fastening mechanism may also include a plurality of positioning holes 102 evenly arranged on the support component 100 and a positioning hole 2 704 arranged on the sliding member 701, and the two positioning holes can be concentrically corresponding to each other. The positioning hole 102 and the positioning hole 2 704 are connected by a pin 705. After the sliding member 701 slides, it finds the corresponding positioning hole 102, and the two positioning holes can be plugged and fixed by the pin 705. This structure can realize the positioning of the positioning member 200 at a fixed position, but cannot realize the positioning at any position. However, this structure is simple and can better adapt to the casting process, and does not require much care. Example

[0063] This embodiment is to achieve a fixed connection of the hinged reinforcement positioning device so as to achieve a good supporting and lifting effect.

[0064] refer to Figure 2 and Figure 3 In this embodiment, it also includes a mounting mechanism for supporting and connecting with the template 6.

[0065] The mounting mechanism includes a fixing rod 501 and a fixing tube 502. One end of the fixing rod 501 is fixedly connected to the supporting component 100 (for example, by welding), and the other end is plugged into one end of the fixing tube 502. Figure 2 and Figure 3 As shown, the plug-in end has a bend, which can achieve a good supporting and plugging effect. The other end of the fixing cylinder 502 is threadedly connected to the screw rod 503 provided on the template 6 through an internal thread.

[0066] That is to say, the fixing tube 502 can be rotated up or down on the screw rod 503, thereby driving the fixing rod 501 to rise and fall, and the placement height of the hinged seam reinforcement is adjusted accordingly to adapt to hinged seam reinforcements of different sizes or to meet different construction placement requirements.

[0067] After the hinged seam reinforcement is placed, the hinged seam reinforcement is fixed on the solidified concrete slab 4 and cannot be moved. The fixing cylinder 502 needs to be loosened to reduce the overall height before the hook 201 or the hanging rod 202 can be separated from the hinged seam reinforcement 3 (such as Figure 3 As shown), and finally disassembly is achieved.

[0068] In addition to the above advantages, the utility model can also play a role in pre-positioning before installing the hinged seam reinforcement. Specifically, the relative positions of the positioning parts can be pre-positioned using the scale lines on the support component, so that the positioning parts are arranged in order according to a certain spacing, and this spacing is also the installation position of the hinged seam reinforcement. In this way, workers do not need to repeatedly measure manually one by one to place the hinged seam reinforcement. Workers only need to hang the hinged seam reinforcement on the positioning parts that have been positioned, which is more convenient to operate.

[0069] The utility model is simple to manufacture, and the required materials are relatively common. It can be made of square tubes, steel bar scraps, and straight threaded sleeves. The single bracket is up to 6m long and the shortest is 4m. It is light in weight and convenient for installation and removal. According to the position and spacing of the hinged reinforcement designed in the drawing, the hooks made of steel bar scraps are welded to the bracket. Two hooks form a group to form a group of hooks for positioning and installing the hinged reinforcement. The designed spacing between the hinged reinforcements is 20cm, and the cutting width is 20cm. The specific dimensions vary according to different construction requirements. To facilitate the subsequent installation of the hinged reinforcement, the spacing between the two hooks is set to 16cm, and the spacing between the two groups of slots is 22cm.

[0070] When installing the hinged joint reinforcement, the hinged joint reinforcement can be directly placed on the bracket slot to complete the positioning and installation. The production efficiency has been significantly improved, and one person only needs 5 minutes to complete the entire installation process. When pouring or vibrating concrete, the hinged joint reinforcement will not be offset, avoiding the tediousness of manual secondary adjustment, which can not only save manpower and material resources, but also significantly improve the appearance quality.

[0071] The following is a comparison between the traditional manual tying method and the current method using positioning devices. The results are as follows:

[0072] Using traditional manual tying method:

[0073] That is, each connection must be manually positioned and tied, and at least two people are required to operate at the same time. When pouring concrete or vibrating, the tie wire may break, and manual re-tying is required, increasing manpower and material expenditures. If the tie wire breaks, it will affect the straightness and height of the hinged reinforcement installation, and manual secondary adjustment is required. Additional personnel are also required to make secondary adjustments or re-tie costs.

[0074] Using the current positioning device method:

[0075] That is, the positioning device is arranged and fixed above the installation position of the hinged reinforcement, and the hinged reinforcement is directly placed (such as hanging) on ​​the positioning piece, and the positioning and installation are completed. Because the positioning piece corresponds to the installation point of the hinged reinforcement, the hinged reinforcement can be positioned in an orderly and regular manner. There is no need to use wire for manual binding, which not only saves the cost of wire binding but also reduces the operation time, and the production efficiency is significantly improved. One person only needs 5 minutes to complete the entire installation process. The materials required to make the tools can be welded with the remaining materials left over from the construction, and the production cost is low. When pouring concrete or vibrating concrete, the hinged reinforcement will not be offset, and the overall straightness after forming is good. There is no need to spend extra personnel for secondary adjustment or re-binding, reducing the labor expenses of workers.

[0076] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
