Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a double-T beam inner mold with a transverse diaphragm and a double-T beam template. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the continuous increase in vehicle ownership has become a common phenomenon. This has led to increasingly serious traffic congestion on existing roads, affecting citizens' travel efficiency and quality of life. To solve this problem, widening roads and increasing the number of lanes is the most direct method. Therefore, more and more areas urgently need to renovate and expand existing roads.

[0003] The renovation and expansion project has a large demand for double T-beams. Due to their thin web and small width-to-span ratio, double T-beams generally increase their lateral stiffness by installing transverse diaphragms. The traditional construction method for double T-beams is to fix the inner formwork of the double T-beam on the pedestal, and the transverse diaphragms of double T-beams are mostly cast in post-construction, that is, the transverse diaphragms are cast separately in the beam storage area after the beam is tensioned, which leads to low construction efficiency.

[0004] To improve construction efficiency, the existing technology uses a method of simultaneously casting the transverse diaphragms and the beam body of a double T-beam. After casting, the beam body needs to be tensioned. During tensioning, the beam body arches and contracts, and the upper part of the beam body drives the outer formwork of the transverse diaphragm to move outward. The transverse diaphragm at the bottom of the beam body squeezes the inner formwork of the transverse diaphragm. The inner formwork of the transverse diaphragm has no buffer space along the longitudinal direction of the beam body, which causes the transverse diaphragm to be squeezed by the inner formwork of the transverse diaphragm, making the transverse diaphragm prone to cracking.

[0005] To avoid cracking of the transverse diaphragms, the existing method of simultaneously casting the transverse diaphragms and the beam body of double-T beams requires the removal of the inner formwork of the double-T beam before tensioning. For example, Chinese Patent 202020240146.4 discloses an inner formwork for precast double-T beams, in which a lifting device is set at the bottom of the integral inner formwork body to drive the inner formwork body to detach from the formwork, so as to realize the detachment of the inner formwork. After the inner formwork body is completely detached, the inner formwork body is pulled out by a winch along the track on the ground, and then the inner formwork body is pulled out by hooking the lifting ring. This method has a relatively complex structure, and the formwork needs to be re-established when casting the next beam body. It also has the problems of cumbersome construction process and low construction efficiency. Utility Model Content

[0006] In view of this, the present invention provides a double-T beam inner mold with a transverse diaphragm and a double-T beam template, which can simultaneously cast the beam body and the transverse diaphragm. When the beam body is tensioned and contracted, the transverse diaphragm and the inner mold of the transverse diaphragm can be prevented from being squeezed, thereby avoiding cracking of the transverse diaphragm. When the beam body is tensioned, there is no need to remove the double-T beam inner mold. The construction is simple and convenient, the production efficiency is high, the structure is simple, and the cost is low.

[0007] To achieve the above objectives:

[0008] A double-T beam inner formwork with transverse diaphragms includes transverse diaphragm inner formwork and standard inner formwork arranged sequentially along the longitudinal direction;

[0009] A buffer gap is provided between the inner template of the transverse beam and the standard inner template along the longitudinal direction. An elastic jacking component is provided on the standard inner template along the longitudinal direction. The elastic jacking component is used to store elastic potential energy when the double T beam is tensioned, so that the stored elastic potential energy can be released after the beam is lifted and demolded to drive the inner template of the transverse beam to move and reset along the longitudinal direction away from the standard inner template.

[0010] Wherein, the longitudinal direction refers to the length direction of the double-T beam.

[0011] As a further improvement to the above technical solution: the elastic pushing assembly includes an elastic element, a first limiting element, a second limiting element, and a push rod that can move longitudinally;

[0012] The elastic element is sleeved on the outer periphery of the top rod, and the first limiting element and the second limiting element are respectively disposed on the top rod. One end of the elastic element abuts against the first limiting element, and the other end of the elastic element abuts against the second limiting element.

[0013] As a further improvement to the above technical solution: a positioning element for limiting the position of the second limiting element is provided between the standard inner template and the second limiting element.

[0014] As a further improvement to the above technical solution: one end of the push rod passes through the first limiting member, and the other end of the push rod passes through the positioning member.

[0015] As a further improvement to the above technical solution: the elastic pushing assembly further includes an adjustment component for adjusting the position of the first limiting member along the longitudinal direction; the adjustment components are respectively disposed on both sides of the first limiting member along the longitudinal direction.

[0016] As a further improvement to the above technical solution: the adjustment assembly includes an adjustment screw and an adjustment nut arranged parallel to both sides of the top rod, the adjustment nut being screwed onto the adjustment screw, and the adjustment nut being located on the side of the first limiting member away from the elastic member.

[0017] As a further improvement to the above technical solution: a sleeve is provided on the outer periphery of the elastic element, the positioning element is fixedly connected to one end of the sleeve, and the adjusting screw is fixedly connected to the outer wall of the sleeve.

[0018] As a further improvement to the above technical solution: a sealing element is provided at the buffer gap.

[0019] As a further improvement to the above technical solution, the sealing element is a rubber strip.

[0020] A double-T beam formwork, wherein the double-T beam formwork is provided with a double-T beam inner formwork with transverse diaphragms as described above.

[0021] Based on the same concept as the aforementioned utility model, this application also provides a double T-beam template, which can be provided with a double T-beam inner mold with a crossbeam as described above.

[0022] The double-T beam inner formwork and double-T beam template provided in this application can simultaneously cast the beam and the diaphragm. By setting a reserved buffer gap between the standard inner template and the inner template of the diaphragm, and installing an elastic jacking component on the standard inner template, the inner template of the diaphragm can slide and retract longitudinally when the beam is tensioned and contracted. The elastic jacking component is compressed and stores elastic potential energy, avoiding squeezing between the diaphragm and the inner template of the diaphragm, thereby preventing cracking of the diaphragm. When the beam is tensioned, there is no need to completely remove the double-T beam inner formwork. After the beam is lifted and demolded, the elastic jacking component releases the stored elastic potential energy to drive the inner template of the diaphragm to move and reset longitudinally away from the standard inner template. The construction is simple and convenient, with high production efficiency, simple structure, and low cost. Attached Figure Description

[0032] The term “include” or any other variation thereof is intended to cover non-exclusive inclusion, which includes not only those elements listed, but also other elements not expressly listed.

[0033] like Figures 1 to 3 As shown, the double T-beam inner formwork with transverse diaphragms in this embodiment includes a transverse diaphragm outer formwork 1, a transverse diaphragm inner formwork 2, and a standard inner formwork 3 arranged sequentially along the longitudinal direction;

[0034] A buffer gap is provided between the inner template 2 of the transverse beam and the standard inner template 3 along the longitudinal direction. An elastic jacking component 4 is provided on the standard inner template 3 along the longitudinal direction. The elastic jacking component 4 is used to store elastic potential energy when the beam body 5 of the double T beam is tensioned, so that the stored elastic potential energy can be released after the beam body 5 is lifted and demolded to drive the inner template 2 of the transverse beam to move and reset along the longitudinal direction away from the standard inner template 3.

[0035] The longitudinal direction refers to the length of beam 5 of the double-T beam, specifically... Figure 1 The left and right directions in the middle.

[0036] The double-T beam inner mold with transverse diaphragms in this embodiment can simultaneously cast the beam 5 and the transverse diaphragm 51. By setting a reserved buffer gap between the standard inner mold 3 and the transverse diaphragm inner mold 2, and installing an elastic jacking component 4 on the standard inner mold 3, the transverse diaphragm inner mold 2 can slide and retract longitudinally when the beam 5 is tensioned and contracted. The elastic jacking component 4 is compressed and stores elastic potential energy, avoiding squeezing between the transverse diaphragm 51 and the transverse diaphragm inner mold 2, thereby avoiding cracking of the transverse diaphragm 51. When the beam 5 is tensioned, there is no need to completely remove the double-T beam inner mold. After the beam 5 is lifted and demolded, the elastic jacking component 4, which is in a compressed state, extends and releases the stored elastic potential energy, driving the transverse diaphragm inner mold 2 to move and reset longitudinally away from the standard inner mold 3. The construction is simple and convenient, with high production efficiency, simple structure, and low cost.

[0037] See details Figure 3 In this embodiment, the elastic pushing assembly 4 includes an elastic element 42, a first limiting element 43, a second limiting element 44, and a push rod 41 that can move longitudinally.

[0038] The elastic element 42 is sleeved on the outer periphery of the top rod 41. The first limiting element 43 and the second limiting element 44 are respectively provided on the top rod 41. One end of the elastic element 42 abuts against the first limiting element 43, and the other end of the elastic element 42 abuts against the second limiting element 44. When the beam 5 is tensioned, the transverse diaphragm 51 presses the inner template 2 of the transverse diaphragm to the right. The inner template 2 of the transverse diaphragm drives the top rod 41 to move to the right. The second limiting element 44 on the top rod 41 moves with the top rod 41, thereby compressing the elastic element 42. The elastic element 42 stores elastic potential energy. The structure is reasonable and effective. Preferably, the elastic element 42 is a helical spring.

[0039] Furthermore, in this embodiment, a positioning element 45 is provided between the standard inner template 3 and the second limiting member 44 to limit the position of the second limiting member 44. After the beam 5 is lifted and demolded, the elastic member 42 releases the stored elastic potential energy, which pushes the push rod 41 to the left through the second limiting member 44. The push rod 41 pushes the inner template 2 of the transverse beam back to its original position. When the second limiting member 44 contacts the positioning element 45, it cannot move further, thereby ensuring that the inner template 2 of the transverse beam automatically returns to its fixed position, further improving the reliability of the elastic pushing assembly 4. Preferably, the first limiting member 43, the second limiting member 44, and the positioning element 45 are all plate parts, which have a simple structure, are easy to process and manufacture, and are convenient for installation and arrangement.

[0040] Furthermore, one end of the push rod 41 passes through the first limiting member 43, and the other end of the push rod 41 passes through the positioning member 45. The first limiting member 43 and the positioning member 45 can provide support and guidance for the push rod 41, so that the push rod 41 can move smoothly in the longitudinal direction.

[0041] Furthermore, in this embodiment, the elastic pushing assembly 4 also includes an adjustment assembly for adjusting the position of the first limiting member 43 along the longitudinal direction. The adjustment assembly is respectively disposed on both sides of the first limiting member 43 along the longitudinal direction. By adjusting the longitudinal position of the first limiting member 43, the preload of the elastic member 42 can be adjusted to meet the usage requirements.

[0042] Furthermore, in this embodiment, the adjustment assembly includes adjusting screws 47 and adjusting nuts 46 arranged parallel to both sides of the top rod 41. The adjusting nuts 46 are screwed onto the adjusting screws 47 and are located on the side of the first limiting member 43 away from the elastic member 42. By rotating the adjusting nuts 46 on the two adjusting screws 47, the first limiting member 43 can be moved longitudinally as a whole, which is simple in structure and convenient in adjustment.

[0043] In a preferred embodiment, the elastic member 42 is provided with a sleeve 48 on its outer periphery, the positioning member 45 is fixedly connected to one end of the sleeve 48, and the adjusting screw 47 is fixedly connected to the outer wall of the sleeve 48, thereby connecting the positioning member 45, the sleeve 48 and the adjusting screw 47 into a whole.

[0044] Furthermore, in this embodiment, a sealing element 6 is provided at the buffer gap to prevent grout leakage during concrete pouring.

[0045] In a preferred embodiment, the sealing element 6 is a rubber strip. The rubber strip deforms under pressure from the inner template 2 of the diaphragm beam, thereby fitting against the inner template 2 and the standard inner template 3, achieving a good sealing effect. The rubber strip also has the advantage of low cost. It is readily understood that in some embodiments not shown, the sealing element may also be made of other elastic materials.

[0046] Based on the same concept as the foregoing embodiments, this application also provides a double-T beam template, which can be provided with a double-T beam inner mold with transverse diaphragms as described above.

[0047] The double-T beam formwork of this embodiment includes the double-T beam inner formwork with transverse diaphragms described above, and therefore also has the aforementioned advantages.

[0048] 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. Therefore, the protection scope of this utility model should be determined by the appended claims.
