Description

Technical Field

[0001] The present application relates to the technical field of bridge engineering equipment, and in particular to a template joint adjustment device. Background Art

[0002] In bridge construction projects, standardized steel formwork is generally used when constructing piers. In order to ensure the appearance quality of the concrete on the pier surface, it is necessary to strictly control the misalignment at the formwork joints (misalignment refers to the phenomenon of relative vertical displacement between two plates at the joints or cracks of the cement concrete pavement).

[0003] Chinese patent number CN213571556U discloses a device for adjusting the joints of pier steel formwork. The device comprises a pair of adjustment members, each consisting of a clamp, a fastener, and an adjuster. The clamp is a frame structure with an opening for accommodating the connectors of the two joined steel formworks. The fastener is located at the top of the clamp. The adjuster is located on one side of the clamp to tighten the two connectors from one side, thereby aligning their edges. This disclosed solution utilizes two adjustment mechanisms simultaneously, utilizing the principle of two-point alignment to quickly adjust the flatness of the steel formwork joints.

[0004] However, in the process of conceiving and realizing the above application, the inventors found that in the actual use of the above disclosed solution, since the sizes of the standard steel templates used each time are different, the device cannot adapt to the size of different templates. During use, the force applied to the device will vary greatly, which will make the device easily broken. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a template seam adjustment device.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A template joint adjustment device, the template joint adjustment device comprising:

[0008] The threaded cylinder has connecting plates fixedly connected on both sides, and a clamping plate is provided on the lower end surface of the connecting plate, and a clamping through hole is opened on the clamping plate;

[0009] Ejector bolts that match the threaded barrel;

[0010] A clamping space for clamping the ear plate of the lower template is formed between the two clamping plates, and the ejector bolt is screwed into the threaded barrel to abut against the ear plate of the upper template.

[0011] Optionally, an adjustment through hole is provided on the connecting plate, and a connecting hole corresponding to the adjustment through hole is provided on the upper end of the clamping plate.

[0012] Optionally, the connecting plate and the clamping plate are detachably connected via adjusting bolts.

[0013] Optionally, the clamping plate is fixed to the ear plate of the lower template by connecting bolts.

[0014] Optionally, the clamping plate is an L-shaped plate.

[0015] Optionally, a ring is provided at one end of the ejector bolt.

[0016] Optionally, the clamping through hole includes at least one.

[0017] Optionally, the outer diameter of the threaded barrel is consistent with the width of the clamping plate.

[0018] Optionally, a dovetail groove is provided on the lower end surface of the connecting plate, a sliding key adapted to the dovetail groove is fixed on the upper end surface of the clamping plate, and the connecting plate is slidably connected to the clamping plate via the sliding key.

[0019] The beneficial effects of the present application are as follows: the present application first clamps the ear plate of the lower template through the clamping plate, and then fastens the ear plate of the lower template to the clamping plates on both sides through connecting bolts at the clamping through holes, and then adjusts the connecting plate and the clamping plate and docks them. Since the threaded barrel will always be located at the center of the clamping plate after the connecting plate and the clamping plate are connected and fixed, no matter what size or thickness of the template the device is applied to, the threaded barrel can always be located at the force center, thereby avoiding large force differences in the device during use, and making the device less likely to be pulled damaged.

[0032] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0033] Example 1:

[0034] See also Figure 1 and Figure 2 , a template joint adjustment device, the template joint adjustment device comprising:

[0035] A threaded barrel 1, with connecting plates 2 fixedly connected on both sides, a clamping plate 4 provided on the lower end surface of the connecting plate 2, and a clamping through hole 5 provided on the clamping plate 4; and also including an ejector bolt 8 matching the threaded barrel 1;

[0036] A clamping space for clamping the ear plate of the lower template is formed between the two clamping plates 4 , and the ejector bolt 8 is screwed into the threaded barrel 1 to abut against the ear plate of the upper template.

[0037] An adjustment through hole 3 is provided on the connecting plate 2, and a connecting hole 6 corresponding to the adjustment through hole 3 is provided on the upper end of the clamping plate 4. The connecting plate 2 and the clamping plate 4 are detachably connected by an adjusting bolt 7. The clamping plate 4 is fixed to the ear plate of the lower template by connecting bolts. The clamping plate 4 is an L-shaped plate, and a ring 9 is provided at one end of the ejection bolt 8. The clamping through hole 5 includes at least one, and the outer diameter of the threaded barrel 1 is consistent with the width of the clamping plate 4.

[0038] Specifically, the pier steel formwork includes an upper formwork and a lower formwork. When the upper formwork and the lower formwork are covered, a joint is formed at the joint. Ear plates are welded to the upper and lower formwork near the joint. The ear plates on the pier steel formwork of different sizes or thicknesses are of the same thickness. The ear plates on the lower formwork are provided with holes for allowing the connection bolts to pass through, and the holes correspond one-to-one with the clamping through holes 5.

[0039] The threaded barrel 1 is in the shape of a hollow cylinder, and an internal thread is provided on the inner wall of the cylinder. The external thread of the ejector bolt 8 is screwed into the internal thread of the threaded barrel 1. Two connecting plates 2 are welded on both sides of the threaded barrel 1. An adjustment through hole 3 is provided in the middle of the connecting plate 2. Two groups of clamping plates 4 are provided accordingly. The clamping plate 4 is an L-shaped plate, and an adjustment through hole 3 corresponding to the adjustment through hole 3 is provided on its upper end surface. At least one clamping through hole 5 is provided on its side. In this embodiment, two clamping through holes 5 are provided, and correspondingly, two holes are also provided on the ear plate welded to the lower template; a ring 9 is provided to facilitate the insertion of a lever, so that the rotational force on the ejector bolt 8 can be better applied through the lever;

[0040] When in use, place the two sets of clamping plates 4 on both sides of the ear plates on the lower template respectively, so that the clamping through holes 5 opened on the clamping plates 4 correspond one to one with the holes opened on the ear plates, and the clamping space for clamping the ear plates of the lower template is formed between the two clamping plates 4, and then screw in the connecting bolts to connect the clamping plates 4 and the ear plates of the lower template into one; place the threaded cylinder 1 above the clamping plates 4, so that the adjustment through holes 3 of the connecting plates 2 correspond one to one with the connecting holes 6 opened on the upper end of the clamping plates 4, and screw in the adjusting bolts 7 so that the connecting plates 2 and The clamping plates 4 are connected as one, and the position of the threaded barrel 1 is fixed. The ejector bolt 8 is screwed into the threaded barrel 1, and the lever is inserted into the ring 9 at one end of the ejector bolt 8. The lever is rotated, and the lever drives the ejector bolt 8 to rotate synchronously, so that the ejector bolt 8 moves in the threaded barrel 1. As the lever rotates, the other end of the ejector bolt 8 gradually approaches the ear plate of the upper template until it abuts the ear plate. The lever is continued to be rotated, and the ejector bolt 8 pushes the upper template to move slowly until the joint between the upper and lower steel molds is flat, and the lever is stopped.

[0041] In this embodiment, the clamping plates 4 first clamp the ear plates of the lower template, and then the ear plates of the lower template are fastened to the clamping plates 4 on both sides by connecting bolts at the clamping through holes 5. The connecting plates 2 and the clamping plates 4 are then adjusted and docked. Since the threaded cylinder 1 is always located at the center of the clamping plates 4 after the connecting plates 2 and the clamping plates 4 are connected and fixed, no matter what size or thickness the device is used for, the threaded cylinder 1 can always be located at the force center, thereby avoiding large force differences during use of the device, and thus making the device less likely to be broken.

[0042] In this embodiment, an adjustment hole 3 is provided on the connecting plate 2, and the clamping plate 4 is configured as an L-shaped plate. A connection hole 6 is provided on the upper end surface of the clamping plate 4. The connection hole 6 is fixed below the adjustment hole 3 via an adjustment bolt 7. In this way, adjustment and tightening by bolt connection are both convenient and have sufficient connection strength.

[0043] In this embodiment, in order to prevent the clamping plate 4 from rotating after being subjected to force, two clamping through holes 5 are provided.

[0044] Example 2:

[0045] In this embodiment, another connection method between the connecting plate 2 and the clamping plate 4 is provided. Specifically, a dovetail groove is provided on the lower end surface of the connecting plate 2, and a sliding key that is compatible with the dovetail groove is fixed on the upper end surface of the clamping plate 4. The connecting plate 2 is slidably connected to the clamping plate 4 through the sliding key.

[0046] Fix the clamping plate 4 and the ear plate of the lower template in the manner of Example 1, and then connect the connecting plate 2 and the clamping plate 4 as a whole through a sliding key. At this time, the threaded barrel 1 is located at the center of the clamping plate 4. Through this connection method, the threaded barrel 1 can also be placed at the force center, thereby avoiding large force differences in the device during use and causing the device to be broken.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
