Description

Technical Field

[0001] This utility model relates to the field of formwork technology for precast beams, specifically to an end mold fixing component and formwork system. Background Technology

[0002] Prestressed concrete small box girders and T-beams are the main beam types used in highway construction in China. However, due to the complex and varied routes, curves, and the need to cross various existing roads and rivers, highway beams have a wide variety of span lengths with a very large range of variation.

[0003] Nowadays, most construction projects use prefabricated steel formwork to improve efficiency and reduce the disassembly and assembly of formwork. The formwork is generally designed according to the maximum beam span length. By installing end molds at different length positions of the formwork, prefabrication of beam spans of different lengths can be achieved.

[0004] The conventional method of fixing end formwork involves installing fixing lugs at the ends of the side formwork and using threaded rods parallel to the longitudinal direction of the side formwork along its edge. The end formwork is locked to the fixing lugs at its ends by the threaded rods when in different positions. However, this method has drawbacks. When the beam length varies significantly, the range of movement of the end formwork also increases. In this case, when the end formwork is far from the end of the side formwork, the threaded rods need to be quite long to lock into place. However, the longitudinal stiffness of the threaded rods is limited. During concrete pouring, due to the lateral pressure of the concrete, longer threaded rods are prone to longitudinal deformation, causing displacement of the end formwork in the longitudinal direction. This results in an increased beam length in the precast beam, affecting precast accuracy and hindering subsequent operations. Utility Model Content

[0007] The end mold fixing component is located on the outer side of the end mold along the longitudinal direction of the end mold and on the inner side of the side mold end.

[0029] Figure 1 A schematic diagram of the existing end mold fixing method, such as Figure 1 As shown, a fixing lug 101 is installed at the end of the side formwork 10, and a lug is also provided on the outer side of the end formwork. The end formwork 20 is locked to the fixing lug 101 by a screw 102 parallel to the longitudinal direction of the side formwork. When the beam length varies greatly, and the end formwork 20 is far from the end of the side formwork 10, the screw 102 needs to be of a longer length to lock with the fixing lug at the end of the side formwork. It is difficult to ensure the longitudinal stiffness of the screw 102. As a result, during concrete pouring, the lateral pressure of the concrete causes the end formwork 20 to shift longitudinally, resulting in a longer beam length in the precast beam, which affects the precast accuracy and is detrimental to subsequent operations.

[0030] like Figure 2 and Figure 3 As shown, this embodiment provides an end mold fixing assembly 30, including an end mold fixing member 31; the end mold fixing member 31 is disposed along the longitudinal direction of the end mold 20 on the outer side of the end mold 20 and is detachably connected to the end mold 20; the top two ends of the end mold fixing member 31 are detachably connected to the side mold back frame 12 respectively, and the bottom of the end mold fixing member 31 is detachably connected to the bottom mold 40.

[0031] The end mold fixing member 31 is disposed on the outer side of the end mold 20 along the longitudinal direction of the end mold 20 and on the inner side of the end of the side mold 10. That is, the end mold fixing member 31 is located between the end of the side mold 10 and the end mold 20.

[0032] According to the embodiment of this application, the end formwork fixing component 30 can be adjusted to change its connection position with the side formwork back frame 12 according to the range of beam length variation of the beam to be precast, so as to meet the precast construction of beams of any length. The end formwork fixing component 30 can be fixed to the side formwork back frame 12, the end formwork 20 and the bottom formwork 40 at the same time, which greatly ensures the accuracy and firmness of the fixing position of the end formwork 20, thereby greatly ensuring the dimensional accuracy of the beam forming.

[0033] like Figure 2 and Figure 4 As shown, in one embodiment, the end mold fixing member 31 is a fixing bracket formed by connecting adjacent four sides in sequence. Further, the fixing bracket includes a top edge, two side edges 319, and a bottom edge 315.

[0034] In a preferred embodiment, the shape of the fixing bracket is consistent with the shape of the beam cross-section, such as... Figure 4 As shown, the end mold fixing component 31 is set as a fixed support structure with the shape of the beam cross-section. The structure is simple, easy to process and install, and low in cost.

[0035] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the side mold back frame 12 is provided with a longitudinal beam 121 along the longitudinal direction of the side mold 10, and the top edge of the fixed bracket extends laterally to both sides along the end mold 20 as a top crossbeam 313, the two ends of the top crossbeam 313 being detachably connected to the longitudinal beam 121.

[0036] The longitudinal beam 121 is preferably disposed above the side formwork back frame 12; The top crossbeam 313 and the longitudinal beam 121 can be detachably connected by bolts; By setting the top crossbeam 313, the end mold fixing component 31 and the side mold back frame 12 can be fixedly installed stably and reliably, thereby effectively ensuring the accurate and secure fixing position of the end mold 20.

[0037] like Figure 3 As shown, in a preferred embodiment, the longitudinal beam 121 is provided with first connecting holes 123 at intervals along the longitudinal direction of the side mold 10 for connecting with the top crossbeam 313, so as to facilitate the installation and fixation of the end mold fixing assembly 30 at different positions.

[0038] The top crossbeam 313 has first mounting holes 314 at both ends corresponding to the first connecting holes 123; in a preferred embodiment, bolts pass through the first mounting holes 314 and the first connecting holes 123 to detachably connect the top crossbeam 313 to the longitudinal beam 121.

[0039] In a preferred embodiment, the bottom edge 315 of the fixed bracket is detachably connected to the bottom mold 40 by bolts.

[0040] Furthermore, the bottom edge 315 of the fixed bracket is provided with a second mounting hole 317 for connecting the bottom mold 40 at its center position, and the bottom mold 40 is provided with second connecting holes 401 corresponding to the second mounting hole 317 at intervals along the longitudinal direction of the bottom mold 40.

[0041] In a preferred embodiment, bolts pass through the second mounting hole 317 and the second connecting hole 401 to detachably connect the bottom edge 315 of the fixing bracket to the bottom mold 40, thereby fixing the fixing bracket onto the bottom mold 40.

[0042] In a preferred embodiment, a plurality of first connecting holes 123 spaced apart on the longitudinal beam 121 and a plurality of second connecting holes 401 spaced apart on the bottom mold 40 correspond one-to-one in the longitudinal direction. Preferably, the first connecting holes 123 and the second connecting holes 401 are located on the same cross-sectional plane at the same interval position.

[0043] Furthermore, the fixed bracket has two sides 319 along the height direction of the end mold 20, and the inner sides of the two sides 319 are symmetrically spaced with connecting ear seats 50 for detachably connecting with the end mold 20.

[0044] By setting the connecting ear 50, the installation and fixation of the end mold fixing component 30 and the end mold 20 can be achieved in a very convenient, stable and reliable manner.

[0045] In a preferred embodiment, the connecting ear seat 50 on the fixed bracket and the ear plate 201 disposed on the outer side of the end mold 20 are detachably connected by a screw 102 to fix the end mold 20 on the fixed bracket.

[0046] Specifically, the installation method of the end mold fixing component 30 in this application embodiment is as follows: When the beam length of the precast beam changes little, the end mold 20 can be directly fixed to the end of the side mold 10. When the beam length of the precast beam changes significantly, for example, when the length is significantly less than the length of the side mold, the installation position of the end mold 20 is far from the end face of the side mold 10. In this case, the end mold fixing component 30 is installed in a suitable position in the template system, and the end mold fixing component 30 is locked to the longitudinal beam 121 of the side mold back frame 12 using bolts. The end mold fixing component 30 is locked to the bottom mold 40 using bolts, and the end mold 20 is locked to the end mold fixing component 30 using screw 102, thereby achieving the purpose of fixing the end mold 20. Within this range, small changes in beam length are adjusted by screw 102.

[0047] Based on the same concept as the aforementioned utility model, this utility model also provides a template system, wherein the template system is provided with the aforementioned end mold fixing component.

[0048] As can be seen from the above embodiments, the adjustable support components and template system involved in this application can determine the connection position between the end formwork fixing components and the side formwork back frame according to the beam length variation range of the beam to be precast, satisfy the precast construction of any beam length, and ensure the accuracy and reliability of the end formwork fixing position, thereby ensuring the dimensional accuracy of the beam forming.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily obtained by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
