Description

Technical Field

[0001] This utility model relates to the field of highway engineering construction technology, and in particular to a highway engineering formwork support mechanism. Background Technology

[0002] When laying concrete on highways, formwork is usually used to support the concrete and shape it.

[0003] In existing highway engineering projects, after C-shaped steel formwork is placed, struts are inserted into the holes of the C-shaped steel formwork. The formwork is pulled by the restraining rods at the ends of the struts to prevent it from opening during concrete pouring. However, when the formwork is removed after the concrete has set, the struts protrude from the concrete subgrade. Therefore, a welding torch is needed to cut the protruding part of the struts. Since highway engineering construction is long, a large number of struts are needed to support the formwork. As a result, cutting equipment needs to be transported when the struts are cut, which consumes a lot of time and manpower. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1: This utility model provides the following... Figure 1-5 The formwork support mechanism shown is applied to steel formwork 1 and includes:

[0036] Support strip 2 is installed on one side of the steel formwork 1;

[0037] The snap-fit ​​assembly is located at one end of the support bar 2 near the steel template 1;

[0038] The first connecting rod 4 is located at one end of the support bar 2 near the steel template 1;

[0039] The second connecting rod 5 is disposed at one end of the first connecting rod 4;

[0040] The disassembly and assembly component 8 is located inside the second connecting rod 5 and is used to connect the first connecting rod 4 and the second connecting rod 5.

[0041] The card-connecting components include:

[0042] The first limiting rod 6, the end of the first limiting rod 6 is fixedly connected to the outer wall of the first connecting rod 4;

[0043] The second limiting rod 7 has its end fixedly connected to the outer wall of the second connecting rod 5.

[0044] One end of the first connecting rod 4 is fixedly connected to one end of the support bar 2, and the other end of the support bar 2 is fixedly connected to a fixing ring 3.

[0045] Furthermore, the steel formwork 1 is an existing C-shaped steel. A transverse insertion hole is provided on the outer wall of the steel formwork 1. The length of the transverse insertion hole is 1.2 times the length of the first limiting rod 6 or the second limiting rod 7, used to insert the second connecting rod 5. The opposite side of the first connecting rod 4 and the second connecting rod 5 is an inclined plane. When the second connecting rod 5 is inserted into the transverse insertion hole, the inclined plane is parallel to the vertical plane. The support bar 2 is a steel bar, and the fixing ring 3 is integrated with the support bar 2. The fixing ring 3 is annular and used to install screws, thereby fixing the support bar 2 to the ground, so that the steel formwork 1, the ground, and the support bar 2 form a right triangle, with the support bar 2 being the hypotenuse of the right triangle. Therefore, based on the height of the transverse insertion hole and the lengths of the support bar 2 and the first connecting rod 4, the following can be established: The inclined surfaces of the first connecting rod 4 and the second connecting rod 5 at corresponding angles, the first limiting rod 6 and the second limiting rod 7 are welded and fixed to the outer walls of the first connecting rod 4 and the second connecting rod 5 respectively. The first limiting rod 6 and the second limiting rod 7 are both set vertically. When inserting into the horizontal insertion hole, the first limiting rod 6 and the second limiting rod 7 need to be rotated to the horizontal direction first, and then inserted into the horizontal insertion hole so that the horizontal insertion hole is located between the first limiting rod 6 and the second limiting rod 7. Then rotate the support bar 2 to make the first limiting rod 6 and the second limiting rod 7 become vertical, thereby clamping the steel template 1. Then fix the fixing ring 3 to the ground with screws to complete the installation of the support mechanism, and then concrete can be poured. This method is the existing technology in the existing field.

[0046] The disassembly and assembly components 8 include:

[0047] Insert rod 81, one end of which is fixedly connected to one end of second connecting rod 5, and cavities are opened inside the insert rod 81 and the second connecting rod 5;

[0048] The locking element is located inside the cavity.

[0049] The first connecting rod 4 has a slot at the end away from the support bar 2, and a locking groove is provided on the inner wall of the slot.

[0050] Furthermore, the size of the slot corresponds to the size of the insert 81, and the size of the locking groove corresponds to the size of the locking block 82.

[0051] In embodiment two, this utility model provides a locking component, applied to the support mechanism in embodiment one. The locking component includes:

[0052] The locking block 82 has an insertion hole on the inner wall of the cavity, and the locking block 82 is inserted into the insertion hole.

[0053] The ends of the linkage block 83 and the locking block 82 are fixedly connected to the outer wall of the linkage block 83;

[0054] Elastic block 84 is located on the side of linkage block 83 away from locking block 82.

[0055] The locking mechanism also includes:

[0056] Extrusion block 85 is disposed at one end of linkage block 83;

[0057] Pressing block 86, one end of which is fixedly connected to one end of extrusion block 85, and a round hole is provided at one end of the inner wall of the cavity, through which pressing block 86 is inserted and connected.

[0058] Furthermore, the size of the insertion hole corresponds to the size of the locking block 82. The locking block 82 is welded and fixed to the linkage block 83. The end of the linkage block 83 facing the pressing block 85 is inclined, and the end of the pressing block 85 facing the linkage block 83 is an isosceles trapezoid. The inclined surface of the isosceles trapezoid corresponds to the inclined surface of the linkage block 83. Two linkage blocks 83 are provided, and the elastic block 84 is provided on one side opposite to the two linkage blocks 83. The end of the elastic block 84 is bonded to the linkage block 83. The elastic block 84 is always in a compressed state in the cavity. The size of the round hole matches the size of the pressing block 86. The contact part with the extrusion block 85 is welded and fixed. By pressing the pressing block 86, the pressing block 86 drives the extrusion block 85. The extrusion block 85, through the end of the isosceles trapezoid, extrudes the inclined surface of the linkage block 83, causing the two linkage blocks 83 to move towards each other. This allows the locking block 82 to move out of the locking groove, separating the second connecting rod 5 from the first connecting rod 4. Thus, after the concrete is poured, pressing the pressing block 86 moves the second connecting rod 5 away from the first connecting rod 4, eliminating the need for cutting equipment and saving time and manpower.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
