At present, for the pouring processing molding of a T beam, the long line mold is adopted for one-time pouring molding, the traditional mold is mainly assembled and disassembled manually, when the large prefabricated T beam (with the length of more than 20 meters) is processed, the traditional manual assembling and disassembling mode is subjected to the problems of low efficiency, difficult management of scattered parts and high safety management difficulty when being implemented, so that the application of a molding device capable of automatically completing the disassembly and assembly of the mold is gradually increased. In particular, as disclosed in the invention patent with publication number CN108274596a, a synchronous hydraulic T-beam template construction device (hereinafter referred to as X1) and the invention patent with publication number CN111168822B, a T-beam template (hereinafter referred to as X2) for road and bridge construction is disclosed, in such a forming device, a long-strip-shaped side template is mostly adopted as a template for forming the side surface of the T-beam, the side template and a support are arranged in a slidable manner, and an oil cylinder is used as driving power to drive the side template to move, so as to complete the assembly and the disassembly of the die. At present, the forming device has the following defects in use:
When large-scale prefabricated T Liang Jia man-hour, the side form of T roof beam unilateral needs a plurality of hydro-cylinders to drive the drawing of patterns simultaneously, because the cohesion has the difference between side form and the T roof beam, leads to each hydro-cylinder to be difficult to synchronous even application of force when pulling the drawing of patterns to this leads to the side form support to take place the deformation under inhomogeneous drawing of patterns force easily.
To solve the problem, in X1, the side mould is firstly demolded with the T beam by adopting a vibrating and loosening demolding cylinder, and then the side mould is synchronously moved in and out by a synchronous diverter. By adopting the mode, the vibration demolding mode is easy to scratch the surface side of the formed T beam, the side template and the side template support are easy to loose and shake in part of working conditions, and the structure of the side template is complex due to the installation of the vibration part, so that the mode still has limitation in application.
In X2, through having increased electromagnetic power part in the side form inboard, the side form utilizes electromagnetic power part to drive to support the clamp plate and stretches out when drawing of patterns to drive earlier and produce the clearance between template body and the T roof beam, with low pressure board and T Liang Tuomo again, with this drawing of patterns pulling force that has reduced the piston cylinder. By adopting the mode, the electromagnetic component added in the side template makes the structure of the side template electric appliance complicated, greatly increases the manufacturing cost and the maintenance cost, and has higher sealing requirement on the gap between the pressing plate and the template body, thus easily causing the problems of water leakage and slurry leakage.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
In the invention, as shown in fig. 1-6, a processing and forming device of a large prefabricated T-beam template is provided, the base comprises a base body 1 and a bottom die 2 arranged at the top of the base body 1, two side die assemblies, wherein the two side die assemblies are respectively arranged at two sides of the bottom die 2, each side die assembly comprises a supporting frame 3 movably arranged at the top of the base body 1 and a side die plate 4 arranged at the inner side of the supporting frame 3, the side die plate 4 is arranged into a side die plate 4 capable of elastically deforming, at least two connecting areas are longitudinally divided between the side die plate 4 and the supporting frame 3, a connecting piece is arranged between at least one connecting area and the supporting frame 3, the connecting piece is arranged to be telescopic between a molding state and a demolding state, the connecting piece is contracted to enable the supporting frame 3 to abut against the side die plate 4 in the molding state, and the connecting piece can be extended to a position of the connecting piece to enable the supporting frame 3 to be arranged to be in a large distance h to be driven to move towards the outer side die plate 3 in the molding state in the connecting area.
When the connecting piece is in a molding state, the connecting piece is contracted, so that the supporting frame 3 is abutted and supported on the side template 4, the shape of the inner surface (the surface facing the T beam 17) of the side template 4 is stable and regular, and casting operation can be performed at the moment.
When demolding is needed, part of the connecting pieces can be switched to a demolding state, the supporting frame 3 and the side form 4 are directly and fixedly connected through different h values of different connecting pieces and/or part of the connecting areas, so that when the supporting frame 3 performs demolding action in the direction deviating from the T beam 17, the supporting frame 3 directly drives the side form 4 to be separated from the T beam 17 in the connecting area (in the working condition where the connecting is carried out) where the supporting frame 3 is directly connected with the side form 4, and when the h value of the connecting piece at the corresponding position is reached in the outward moving distance of the supporting frame 3 in the connecting area of the connecting pieces, the supporting frame 3 drives the side form 4 to be separated from the T beam 17 in the part of the connecting area, and therefore the supporting frame 3 can gradually pull and separate the side form 4 from the T beam 17 in the outward moving process.
The improved technical effect of the invention is that firstly, the support frame 3 can continuously demould different connection areas of the side template 4 in the outward moving process, the part between the demoulding area and the rear demoulding area is separated slowly by utilizing the elastic deformation of the side template 4, and compared with the integral driving side template 4 for direct demoulding, the invention can reduce the resistance which needs to be overcome in the outward moving process of the support frame 3, even if the support frame 3 is stressed unevenly due to the driving force difference in the length direction of the T beam 17, the uneven force generated by the support frame 3 is smaller, thereby reducing the working condition of deformation of the support frame 3 caused by the uneven force difference.
Secondly, by adopting the integrated side template 4, compared with the mode of dividing the side template 4 into a pressing plate and a template body which are driven separately in the prior patent X2, the inner surface of the side template 4 is more regular, which is beneficial to improving the forming quality of the T beam 17;
Thirdly, the side template 4 is gradually demoulded with the T beam 17 in regions when the driving part of the supporting frame 3 is driven to pull the supporting frame 3 outwards, so that the power load on the driving part is reduced, and compared with the vibration demould mode adopted by X1, the demould mode can avoid the working condition of friction scratch of the T beam 17 between the side template 4 and the T beam 17 caused by vibration demould, and can simplify the installation structure of the vibration generating mechanism on the side template 4.
Fourth, the invention provides the demolding power of the side form 4 by driving the driving part of the supporting frame 3, and compared with the mode of driving the pressing plate to push out by adopting the electromagnetic power part in X2, the invention does not need to additionally increase the demolding power part of the side form 4, and has relatively simple structure and relatively lower construction cost and maintenance cost.
In the embodiment shown in fig. 1, for the structure of the connecting piece in the invention, more specifically, the connecting piece comprises a plurality of connecting posts 5 which are installed on the side templates 4 at intervals along the length direction of the side templates 4, a limiting block 6 is arranged on one side of the connecting posts 5 away from the side templates 4, the connecting piece also comprises a supporting plate 7 which is arranged on the supporting frame 3, the supporting plate 7 is provided with a guide hole 8 for the connecting posts 5 to pass through, the connecting piece also comprises a supporting block 9 which is movably arranged on one side of the supporting plate 7 away from the side templates 4, the supporting block 9 moves between a molding position and a demolding position, the supporting block 9 can be abutted between the limiting block 6 and the supporting plate 7 when the supporting block 9 is positioned at the molding position, so that the connecting posts 5 drive the side templates 4 to be abutted with the supporting frame 3, the connecting posts 5 extend from the supporting frame 3 to the side templates 4 by a set distance h in the direction, and the limiting block 6 and/or the supporting block 7 are abutted against the limiting block 7 when the supporting block 9 is positioned at the demolding position.
As shown in fig. 4 and 5, when the connecting piece is in the molding state, the supporting block 9 moves to the molding position, the supporting block 9 abuts between the limiting block 6 and the supporting plate 7, and at this time, the connecting column 5 is contracted inside the supporting frame 3, so that the connecting column 5 tightens the sideform 4 against the supporting plate 7, and at this time, the supporting plate 7 can be made to stably support the sideform 4 when casting molding can be performed inside the sideform 4.
When the connecting piece is in the demolding state, as shown in fig. 6, the supporting block 9 is moved to the demolding position, at this time, in the state that the side form 4 is abutted with the supporting frame 3, the limiting block 6 can move towards the direction of the T beam 17 for a set distance h and then abut on the supporting block 9, at this time, when the supporting frame 3 further moves outwards, the side form 4 can be pulled outwards through the connecting column 5, so that demolding is performed.
It can be seen that the support block 9 is used as a 'cushion block' between the support plate 7 and the limiting block 6, and the thickness of the cushion block between the limiting block 6 and the support plate is switched by moving the support block 9, so that the scalability of the connecting column 5 in the direction of the support frame 3 towards the T beam 17 is adjusted. By such arrangement, not only the structure of the connecting piece is simplified, but also the supporting and limiting part of the supporting block 9 can be utilized stably in the molding state so as to maintain the abutting stability of the side template 4 and the supporting frame 3.
In the embodiment shown in fig. 1, for the moving structure of the supporting block 9, more specifically, the connecting piece includes a sliding plate 10 slidably disposed on the supporting plate 7 along the length direction of the supporting plate 7, the sliding plate 10 is respectively provided with the supporting block 9 at a position corresponding to each of the connecting posts 5, the supporting block 9 is provided with a first supporting portion 901 and a second supporting portion 902 along the sliding direction of the sliding plate 10, the thickness of the first supporting portion 901 is greater than that of the second supporting portion 902, the connecting piece is in a molded state when the sliding plate 10 drives the first supporting portion 901 to move to the position of the limiting block 6, and the connecting piece is in a demolding state when the sliding plate 10 drives the second supporting portion 902 to move to the position of the limiting block 6.
As shown in fig. 2, 5 and 6, the support block 9 of the present invention is provided with a first support portion 901 and a second support portion 902 having different thicknesses, and a connection inclined surface is provided between the first support portion 901 and the second support portion 902, and when the first support portion 901 moves to the position of the stopper 6, the connection column 5 can be moved and contracted in a direction away from the T beam 17, and at this time, the support frame 3 abuts against the sideform 4 to stabilize the shape of the sideform 4. When the second supporting portion 902 moves to the position of the limiting block 6, due to the small thickness of the second supporting portion 902, when the supporting frame 3 starts to move outwards, and the side form 4 is not separated from the T beam 17, the connecting column 5 can extend towards the direction of the T beam 17 until the connecting region of the connecting column 5 and the side form 4 at the corresponding position is moved outwards to be demoulded after the second supporting portion 902 abuts against the limiting block 6.
According to the invention, the inclined plane is arranged, so that the limit block 6 can smoothly move when the slide plate 10 moves to enable the support block 9 to move towards the position of the first support part 901 corresponding to the limit block 6 at the position of the second support part 902 corresponding to the limit block 6.
The slide plate 10 of the present invention is provided with a slide rail having a slide groove in which both side edges of the slide plate 10 are slidably installed, as shown in fig. 2 and 4, the support plate 7 of the present invention is mounted. Therefore, when the state of the connecting piece needs to be adjusted, the sliding plate 10 can be dragged to drive the plurality of supporting blocks 9 to move so as to simultaneously complete the position switching of the supporting blocks 9 at the positions of the plurality of connecting columns 5. In addition, as shown in fig. 2, the present invention adopts the long slide plate 10 to switch the states of the connecting posts 5 of the same connecting area of the side form 4 together, so that the connecting piece action structure of each connecting area can be conveniently arranged in the longitudinal direction of the supporting frame 3.
In the embodiment shown in fig. 1, for the movement of the slide plate 10, more specifically, as shown in fig. 2, the two outer ends of the slide plate 10 are respectively provided with connection rings, and when the slide plate 10 needs to be moved, external tension members can be connected to the pull rings and pull the slide plate 10 to move.

The supporting frame 3 of the invention comprises a plurality of groups of upright posts and cross beams as shown in fig. 1, wherein the supporting plate 7 is connected to the upright posts through a hollowed-out frame structure (with an operation hole for operating nuts), so that the supporting frame 3 of the frame structure is formed, and when the side templates 4 are required to be disassembled and assembled, staff can operate the supporting frame from the upright posts.
In the embodiment shown in fig. 1, for the structure of the present invention, more specifically, the side form 4 is provided with an upper side form 14 at the bottom portion corresponding to the transverse section of the T-beam 17, the connecting piece is arranged between the side of the upper side form 14 away from the side form 4 and the supporting frame 3, the upper edge of the upper side form 14 extends to the upper edge of the transverse section of the T-beam 17, the lower edge extends to the lower edge of the transverse section of the T-beam 17, the side form 4 is provided with at least two connecting areas at intervals below the upper side form 14, at least one connecting area is arranged above, each connecting area is respectively provided with the connecting piece, the h value of the connecting piece corresponding to the upper side form 14 and each connecting piece below the connecting piece is gradually increased from bottom to top, and the h value of the connecting piece corresponding to the upper side form 14 is larger than the h value of the connecting piece above.
As shown in fig. 2 and 3, the transverse section of the T beam 17 is provided with an upper die frame 14 with a substantially triangular cross section, the upper edge of the upper die frame 14 extends to the upper edge of the transverse section of the T beam 17 of the side die plate 4, and the lower edge of the transverse section of the T beam 17 of the side die plate 4 extends to the lower edge of the transverse section of the T beam 17 of the side die plate 4, so that the shape of the transverse section of the T beam 17 of the side die plate 4 can be stably and fixedly supported by the upper die frame 14. The side form 4 forms a reinforcing strip 15 through the upper side form 14 at the upper side form 14, so that the side form 4 can stably transfer the transverse tension of the support frame 3 at the transverse section of the T beam 17.
As shown in fig. 2 and 3, the sideform 4 is provided with three connection areas on the lower side of the upper side die carrier 14 and one connection area on the upper side.
