Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a prefabricated box beam curing shed. Background Art

[0002] Prefabricated box girders need to be cured after casting. In order to improve the curing efficiency, the curing of prefabricated box girders is usually carried out in a curing shed. The roof of the existing curing shed is mostly a fixed connection structure. When the temperature in the shed is too high, it is difficult to complete the heat dissipation by opening the roof. Therefore, the inventor proposes a prefabricated box girder curing shed. Utility Model Content

[0003] The purpose of the present application is to provide a prefabricated box beam curing shed, which has an openable and closable shed roof and can dissipate heat in the shed by opening the shed roof.

[0036] Example 1

[0037] See also Figure 1-Figure 2 This embodiment provides a prefabricated box beam curing shed to solve the problem that the roof of the existing curing shed is difficult to open for heat dissipation.

[0038] In this embodiment, the prefabricated box beam curing shed includes a shed roof 20 opposite to the top of the two side walls 10, a first connecting portion 11 is provided on the top of the side wall 10, the first connecting portion 11 has a limit hole 12 and an adjustment hole 13 arranged axially in sequence, a second connecting portion 21 is provided at the lower end of the shed roof 20, the second connecting portion 21 has a rectangular mounting hole 22 extending along the axial direction, a connecting rod 23 is slidably clamped in the mounting hole 22, a spring 24 is compressed between the connecting rod 23 and the mounting hole 22, a limit column 25 is provided at the outer end of the connecting rod 23, and a limit plate 251 uniformly distributed along the circumferential direction is provided on the surface of the limit column 25, the limit plate 251 corresponds one-to-one to the limit groove 121 formed on the inner wall of the limit hole 12, and the limit column 25 can rotate after retreating into the adjustment hole 13.

[0039] In this embodiment, the limit column 25 is pressed from the limit hole 12 into the adjustment hole 13, so that the connecting rod 23 as a whole can rotate with the roof 20. After the roof 20 is opened to a set angle, the spring 24 pushes the connecting rod 23 outward, so that the limit column 25 is engaged with the limit hole 12 again, thereby limiting the position of the roof 20, making it easier to dissipate heat in the shed by opening the roof 20.

[0040] It should be noted that the prefabricated box girder curing shed of the present embodiment comprises two side walls 10 and two roofs 20 as a whole. The roofs 20 are arranged one by one with the side walls 10, and the two side walls 10 remain arranged in parallel. When the two roofs 20 are butt-jointed, the top can be closed. The prefabricated box girder 30 is placed as a whole in the space enclosed by the two side walls 10 and the two roofs 20 for curing. In actual use, a door panel can be provided at the front and rear ends of the two side walls 10 respectively, so as to place the prefabricated box girder 30 as a whole inside the closed space.

[0041] In addition, the first connecting portion 11 is integrally formed with the side wall 10, and an ear plate is fixedly connected to the top of the side wall 10 on the side opposite to the first connecting portion, and the ear plate is used to form a hinge with the other end of the roof 20. The limiting hole 12 and the adjusting hole 13 are formed inside the first connecting portion 11, and the limiting hole 12 and the adjusting hole 13 are coaxially arranged, and the axes of the two are parallel to the longitudinal direction of the side wall 10. The diameter of the limiting hole 12 is smaller than the diameter of the adjusting hole 13, and the limiting groove 121 is formed on the inner wall of the limiting hole 12. On the upper side, the overall extension direction of the limit groove 121 is parallel to the axis of the limit hole 12, the limit groove 121 is evenly distributed along the circumference of the limit hole 12, and the limit groove 121 and the adjustment hole 13 are located on the same circumferential surface, so that the limit column 25 can always remain coaxial with the adjustment hole 13 after retreating into the adjustment hole 13, which is used to avoid the limit column 25 from offsetting inside the adjustment hole 13 and ensure that the limit column 25 can smoothly move into the limit hole 12 again after rotating the set angle.

[0042] In addition, the second connection part 21 is integrally formed with the roof 21, and the second connection part 21 is constructed as a round rod as a whole. The axis of the second connection part 21 is parallel to the longitudinal direction of the side wall 10, and the second connection part 21 can be rotatably connected to the top of the side wall 10 around its own axis, and the second connection part 21 is used to adjust the hole 13 to maintain a coaxial arrangement. The end of the second connection part 21 corresponding to the first connection part 11 is provided with a mounting hole 22, and the mounting hole 22 is constructed into a rectangle along the cross section. The mounting hole 22 is arranged as a whole on the axis of the second connection part 21, and an avoidance opening 221 is opened at the outer end of the mounting hole 22, and the avoidance opening 221 is constructed into a rectangle along the cross section.

[0043] The connecting rod 23 is constructed as a whole in the shape of a longitudinal rectangular rod. The outer shape of the connecting rod 23 is adapted to penetrate the interior of the mounting hole 22, so that the connecting rod 23 cannot rotate inside the mounting hole 22. The connecting rod 23 is only allowed to slide along the extension direction of the mounting hole 22. The connecting rod 23 is restricted between the inner end of the avoidance opening 221 and the inner end surface of the mounting hole 22. A receiving hole 231 is opened inside the connecting rod 23, and the receiving hole 231 is coaxially arranged with the second connecting portion 21. The spring 24 is inserted into the receiving hole 231, and the spring 24 is compressed in the receiving hole 231. Between the bottom of the hole and the bottom of the mounting hole 22, the spring 24 always maintains an outward thrust on the connecting rod 23. A transition rod 26 is fixedly connected between the left end face of the connecting rod 23 and the right end face of the limiting column 25. The transition rod 26 is adaptively arranged in the avoidance opening 221. The limiting column 25 and the adjustment hole 13 are coaxially arranged, and a limiting plate 251 that is adaptive to the shape of the limiting groove 121 is fixedly connected to the outer wall of the limiting column 25. The limiting plate 251 can slide along the limiting groove 121, so that the limiting column 25 as a whole can retreat into the adjustment hole 13 and can rotate inside the adjustment hole 13.

[0044] It should be noted that when the limit column 25 is separated from the limit hole 12 and retreats into the adjustment hole 13, the inner end of the connecting rod 23 abuts against the bottom of the mounting hole 22; when the limit hole 25 is separated from the adjustment hole 13 and inserted into the limit hole 12, the outer end of the connecting rod 23 abuts against the inner end surface of the avoidance opening 221.

[0045] During use, when heat dissipation is required in the shed, the limit column 25 is first pressed into the adjustment hole 13, so that the limit column 25 loses the limiting effect of the limit hole 12, and then the worker pushes the roof 20 upward to an appropriate angle in the shed, and finally releases the pressure on the limit column 25. Under the push of the spring 24, the limit column 25 moves into the limit hole 12 again, and the opening angle of the roof 20 can be fixed by utilizing the snap-fitting cooperation between the limit plate 251 and the limit groove 121.

[0046] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
