Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a position adjustment mechanism for a diaphragm mould. Background Art

[0002] When constructing an elevated highway or bridge, in order to improve the construction efficiency, a complete highway will be divided into multiple splicing sections. Each splicing section is cast in advance with concrete and steel bars. When in use, the corresponding splicing section is transported to the construction site and spliced ​​to complete the construction of the predetermined road section. The splicing section usually includes a T-beam, which includes a web that plays a supporting role. The top of the web has a wing extending laterally outward. In order to increase the stability of the T-beam, cross-diaphragm components perpendicular to the web are set on both sides of the web. The existing T-beam and cross-diaphragm components are cast in one go using a set of molds, but such a design is difficult to cope with road sections with variable shapes. Figure 8 As shown, in the straight section of the highway, multiple T-beams extend in the straight direction, and the diaphragm components are in a horizontal state. However, when the highway or bridge is affected by the terrain and turns, the T-beams of the corresponding section must also be bent into a corresponding arc, resulting in changes in the number and position of the diaphragm components. For example, the diaphragm components of the turning section will have a certain deflection angle relative to the diaphragm components of the straight section. In this way, the T-beams at the corresponding turning section need to be re-made into molds, which has a high consumption cost and is also easy to affect the construction progress of the road.

[0003] The applicant has improved the existing deficiencies by forming the T-beam separately and then casting diaphragm components on both sides of the web of the formed T-beam, so that the diaphragm is secondary formed relative to the T-beam. The mold of the T-beam no longer needs to consider the setting position and number of the diaphragms, and only needs to form the T-beam, thereby reducing the cost of the mold and ensuring the construction progress of the road; however, when forming the diaphragm component, diaphragm molds independent of the T-beam mold need to be set on both sides of the web. For T-beams of various specifications, the height position of the diaphragm mold needs to be adjusted to the right position. It is also necessary to consider that the diaphragm mold remains stable when pouring concrete, and there will be no misalignment of the diaphragm component. Therefore, a position adjustment mechanism for the diaphragm mold needs to be developed. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a position adjustment mechanism for a diaphragm mold, which drives the supporting plate used to support the diaphragm mold to rise and fall to the corresponding position through a lifting mechanism, and uses a telescopic rod to keep the diaphragm mold at the corresponding position upright, so that the diaphragm mold can remain stable at the corresponding position of the web, so that the diaphragm component can be accurately formed without misalignment.

[0009] Preferably, the first movable rod is threaded with a first nut. When the first movable rod is extended and retracted into place, the first nut is rotated and abutted against the end of the first fixed rod to limit the first movable rod from rotating along its own axis, so that the diaphragm mold remains stable.

[0012] Preferably, a guide assembly is further included, which includes a guide rod fixed to the ground and extending longitudinally. A guide hole is provided on the support plate, and the guide rod is passed through the guide hole to guide the lifting and lowering of the support plate.

[0013] Preferably, the guide rod is a screw rod, and the thread on the screw rod is matched with a load-bearing nut located at the lower end of the support plate. When the height of the support plate is adjusted to the right position, the load-bearing nut is rotated and fits against the lower end surface of the support plate to share the load-bearing force of the scissors mechanism on the diaphragm mold.

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] The specific implementation methods of the utility model are as follows:

[0030] like Figure 1-7 As shown, this embodiment provides a position adjustment mechanism for a diaphragm mold, which is applied in the process of secondary molding of the diaphragm. The steps of secondary molding of the diaphragm include:

[0031] S1: pre-embedded internal threaded sleeve 2; when the T-beam 1 is cast separately according to a predetermined shape, multiple internal threaded sleeves 2 communicating with the outside are pre-embedded at the left and right sides of the web 11 of the T-beam 1 according to a predetermined layout;

[0032] S2: Setting up a connection skeleton 3; pre-setting a plurality of connection rods 31 corresponding to the number of the internally threaded sleeves 2. The connection rods 31 may be relatively strong steel bars, each with a threaded section at one end thereof. The threaded sections of the plurality of connection rods 31 are sequentially screwed into the corresponding internally threaded sleeves 2 in a horizontal direction to form a connection skeleton 3 on the left and right sides of the web 11.

[0033] S3: Setting the mold; setting the diaphragm mold 4 around the corresponding connecting frame 3, and making the diaphragm mold 4 close to the web 11;

[0034] S4: Molding; the upper end of the diaphragm mold 4 has a reserved pouring port 4a, through which concrete is poured into the diaphragm mold 4 to form a diaphragm member 7, so that the diaphragm member 7 and the connecting frame 3 together form the diaphragm; wherein, the diaphragm member 7 relies on the threaded connection force formed between the connecting frame 3 and the internal threaded sleeve 2 to be stably connected to both sides of the web 11 of the T-beam 1 to ensure that the diaphragm will not separate from the T-beam 1, thereby making the secondary molded diaphragm achieve the same effect as the diaphragm directly molded once with the T-beam 1.

[0035] Further, if Figure 3-4 As shown, the diaphragm mold 4 includes a first enclosure 42 located on the front and rear sides of the connecting frame 3 and parallel to the connecting rod 31. A plurality of longitudinally crossed reinforcing ribs 43 are provided on the outer wall of the first enclosure 42. Considering the subsequent casting connection between multiple T-beams 1, the horizontal length of the connecting rod 31 is greater than the horizontal length of the first enclosure 42. A second enclosure 41 perpendicular to the connecting rod 31 is connected between the two first enclosures 42 by a threaded connection, and a plurality of positioning holes corresponding to the multiple connecting rods 31 are reserved on the second enclosure 41; the other end of the connecting rod 31 without a threaded section passes through the corresponding positioning hole, so that after the diaphragm component 7 is formed, multiple connecting rods 31 are exposed outside the diaphragm component 7; the positioning hole can reserve space for the connecting rod 31 to pass through, and it is also convenient for the diaphragm mold 4 to be set in place at a predetermined position, so that after the diaphragm component 7 is formed, the exposed connecting rod 31 part can be cast and connected with the diaphragm component 7 on other T-beams 1, so that multiple side-by-side T-beams 1 are connected as one.

[0036] Furthermore, considering the demolding and positioning issues of the diaphragm mold 4, the first enclosure 42 and the second enclosure 41 are disassembled and assembled through a threaded connection, wherein the first enclosure 42 has a support plate 46 on one end facing the second enclosure 41, which is attached to the second enclosure 41, and the support plate 46 and the second enclosure 41 are provided with waist-shaped grooves 47 with corresponding positions. When the connecting rod 31 passes through the positioning hole, the threaded fastener is inserted into the waist-shaped groove 47 and is locked by a nut, so that the first enclosure 42 and the second enclosure 41 form a threaded connection; compared with opening a round hole, the waist-shaped groove 47 can provide sufficient penetration space for the threaded fastener, even if there is a size or position deviation between the support plate 46 and the second enclosure 41, the first enclosure 42 and the second enclosure 41 can also be connected in place, thereby successfully completing the forming of the diaphragm.

[0037] Furthermore, different specifications of T-beams 1 have different positions for setting the diaphragms. Therefore, in this embodiment, the diaphragm mold 4 is adjusted into place by a position adjustment mechanism of the diaphragm mold. For the convenience of explanation, the mechanism is referred to as the adjustment mechanism 5. The adjustment mechanism 5 includes a supporting assembly, and the supporting assembly includes a supporting plate 51 for supporting the diaphragm mold and a lifting mechanism arranged at the bottom end of the supporting plate 51; the diaphragm mold 4 has a bottom plate 45 connected to the first enclosure 42 and the second enclosure 42, and the bottom plate 45 is supported by the supporting plate 51. Two telescopic rods 54 are symmetrical in front and back on the supporting plate 51. The telescopic rods 54 include a first fixed rod 541 and a first movable rod 542 that are sleeved with each other. The first fixed rod 541 is hinged on the supporting plate 51, and the two first movable rods 542 are hinged on the supporting plate 51. The movable rod 542 is respectively used to be hinged to the front and rear ends of the diaphragm mold 4; specifically, in this embodiment, a hinge seat is provided on the support plate 51, one end of the telescopic rod 54 is hinged to the hinge seat, and the other end is hinged to the corresponding first enclosure 42. In this embodiment, the other end of the telescopic rod 54 is hinged to the reinforcing rib plate 43 provided on the first enclosure 42, and the lifting mechanism can drive the support plate 51 to move to the corresponding position along the longitudinal direction to adjust the position of the diaphragm mold 4 in the longitudinal direction; the first movable rod 542 can be extended and retracted relative to the first fixed rod 541 and stay at the corresponding position to form support for the front and rear sides of the adjusted diaphragm mold 4, so that the diaphragm mold 4 will not fall forward and backward, so as to avoid dislocation when the diaphragm component 7 is formed.

[0038] Furthermore, taking into account cost issues and adjustment efficiency, the telescopic rod 54 in this embodiment is a threaded telescopic rod, and the telescopic rod 54 includes a first fixed rod 541 and a first movable rod 542 that are threadedly connected. The first fixed rod 541 is an internally threaded tube, and the first movable rod 542 is an externally threaded rod that is threadedly fitted in the internally threaded tube. By adjusting the threaded fitting length of the first fixed rod 541 and the first movable rod 542, the telescopic length of the telescopic rod 54 itself can be changed, and the first movable rod 542 can be extended and extended relative to the first fixed rod 541 and stay at the corresponding position; the threaded fitting first movable rod 542 and the first fixed rod 541 have a simple structure, are easy to adjust, and have low cost. After being screwed into place, the self-locking characteristics of the thread can ensure that the first movable rod 542 will not loosen in the reverse direction, thereby preventing the diaphragm mold 4 from falling forward and backward.

[0039] Furthermore, after the first fixed rod 541 and the first movable rod 542 are threaded together and the telescopic length is adjusted into place, although the first movable rod 542 will not slide in the opposite direction in the axial direction, it is easy to produce a rotation tendency in the circumferential direction, affecting the position accuracy of the diaphragm mold 4. Therefore, a first nut 543 is threadedly fitted on the first movable rod 542. When the first movable rod 542 is telescoped into place, the first nut 543 is rotated and attached to the end of the first fixed rod 541 to limit the first movable rod 542 from rotating along its own axis, so that the diaphragm mold 4 remains stable.

[0040] Furthermore, the lifting mechanism is an existing scissor-type lifting mechanism 52; the scissor-type lifting mechanism 52 has low cost and simple operation, and the scissor-type lifting mechanism 52 is driven to lift and lower by a hydraulic cylinder, and a plurality of universal wheels 55 are provided at the bottom end of the scissor-type lifting mechanism 52; it is convenient to transport the diaphragm mold 4 to the corresponding position; the adjustment mechanism is also provided with a manual oil pump 53 for controlling the lifting of the hydraulic cylinder; the manual oil pump 53 is simple to operate, and by controlling the manual oil pump 53, the support plate 51 can be lifted and lowered within the range of 100mm-500mm, so as to move the diaphragm molds 4 of different specifications to the corresponding height positions, thereby ensuring that the diaphragm component 7 is smoothly formed at the predetermined position.

[0041] Furthermore, in order to make the lifting process of the base 51 more precise and smooth, the adjustment mechanism 5 also includes a guide assembly, which includes a guide rod 56 fixed to the ground and extending longitudinally. A guide hole is provided on the support plate 51, and the guide rod 56 is passed through the guide hole to guide the lifting and lowering of the support plate 51.

[0042] Furthermore, considering that the entire diaphragm mold 4 is heavy after pouring cement, it will generate greater pressure on the scissors-type lifting mechanism 52. Therefore, the guide rod 56 in this embodiment is a screw rod, and the thread on the screw rod is matched with the load-bearing nut 561 located at the lower end of the support plate 51. When the height of the support plate 51 is adjusted to the right position, the load-bearing nut 561 is rotated and fits against the lower end surface of the support plate 51 to share the load-bearing force of the scissors-type mechanism on the diaphragm mold 4, thereby protecting the scissors-type lifting mechanism 5.

[0043] Furthermore, the diaphragm mold 4 includes a top plate 44 located at the top of the connecting frame 3. In order to make the upper end of the diaphragm mold 4 close to the web 11 and avoid a gap between the upper end of the diaphragm mold 4 and the web 11, a pressing component for pressing the diaphragm mold 4 inward is provided between the wing plate 12 of the T-beam 1 and the top plate 44. The pressing component includes a telescopic pressing rod 6 provided between the top plate 44 and the wing plate 12 of the T-beam 1. The telescopic length of the telescopic pressing rod 6 is adjusted to make the diaphragm mold 4 close to the web 11 of the T-beam 1 inward, so as to prevent the upper end of the diaphragm mold 4 from leaking during concrete pouring. In this embodiment, the method of setting the pressing component is simple and efficient. Specifically, since the T-beams need to be poured and connected, a plurality of U-shaped steel bars are provided at the end of the wing plate 12 of the T-beam 1, which are spaced front and back and exposed. The skeleton 13 has two supports 65 spaced apart from each other on the top plate 44, and the two supports 65 are connected by a cross bar 66; a horizontal bar 64 is inserted into the U-shaped steel skeleton 13, and then the two ends of at least one telescopic top pressure rod 6 are respectively hinged on the cross bar 66 and the horizontal bar 64 to set the telescopic top pressure rod 6 in place; in this embodiment, the two telescopic top pressure rods 6 are set between the cross bar 66 and the horizontal bar 64; when setting the telescopic top pressure rod 6, by inserting a horizontal bar 64 into the U-shaped steel skeleton 13, the U-shaped steel skeleton 13 on the T-beam is effectively utilized as a force support point, and there is no need to drill holes on the wing plate 12 of the T-beam 1 or to set up additional connecting parts. The operation is simple. After the diaphragm component 7 is cast, it is only necessary to pull the horizontal bar 64 out of the U-shaped steel skeleton 13, and the efficiency of disassembly and assembly is also high.

[0044] Furthermore, the telescopic push rod 6 can be a cylinder or a threaded telescopic rod. Considering the cost, adjustment efficiency, and adjustment accuracy, the threaded telescopic rod is preferably selected in this embodiment. The telescopic push rod 6 includes a second fixed rod 61 and a second movable rod 62 that are threadedly connected. The length of the threaded fit of the second fixed rod 61 and the second movable rod 62 is adjusted to change the telescopic length of the telescopic push rod 6. The adjustment method of threaded engagement is simple and efficient. After being screwed into place, the self-locking property of the thread ensures that the second movable rod 62 will not loosen in the reverse direction, thereby preventing the diaphragm mold 4 from moving away from the web 11 of the T-beam 1. The second movable rod 62 is threaded with a second nut 63. When the second movable rod 62 is telescoped into place, the second nut 63 is rotated and attached to the end of the second fixed rod 61 to limit the second movable rod 62 from rotating along its own axis, thereby keeping the diaphragm mold 4 stable.

[0045] Furthermore, in addition to the top pressing assembly provided at the upper end of the diaphragm mold 4, in this embodiment, a component is also provided at the lower end of the diaphragm mold to make the diaphragm mold 4 close to the web. Specifically, Figure 7As shown, in order to facilitate the setting of the diaphragm mold 4, the bottom of the web 11 lifts the entire T-beam 1 through the support beam 14 to separate the T-beam 1 from the ground. On the left and right sides of the web 11, the supporting plates 51 of the two adjustment mechanisms 5 are provided with connecting seats 81. A pull rod 8 is set between the two connecting seats 81 to prevent the two adjustment mechanisms 5 from moving away from each other. The pull rod 8 passes through the gap between the web 11 and the ground. The connection method of the pull rod 8 and the connecting seat 81 can be a threaded connection, so that the two diaphragm molds 4 are always close to the two sides of the web 11; to prevent the lower end of the diaphragm mold 4 from leaking when pouring concrete.

[0046] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
