Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings:
the first embodiment is as follows: the present embodiment is described with reference to fig. 1 to 4. The quick fixing support for the diagonal bracing of the bowl-buckle type formwork support frame comprises a formwork support frame diagonal bracing 1, four ground anchor steel bars 2, two shoulder pole beams 3, a support 4, a fixing bolt 5 and a concrete block 6;
the shape of the ground anchor steel bar 2 is of an inverted U shape, four ground anchor steel bars 2 are enclosed into a rectangle, the lower part of the ground anchor steel bar is inserted into the ground and fixed on the ground through a concrete block 6, a support 4 is arranged on the concrete block 6, four ground anchor steel bars 2 are positioned on the front side and the rear side of the support 4, two parallel triangular steel plates are vertically fixed on the support 4, each triangular steel plate is provided with a through hole at the same position, the lower part of the template support bracket diagonal bracing 1 is also penetrated with a through hole, a fixing bolt 5 penetrates through the two triangular steel plates and the through hole at the lower part of the template support bracket diagonal bracing 1, the template support bracket diagonal bracing 1 and the support 4 are hinged through the fixing bolt 5, two shoulder pole beams 3 are mutually parallel and respectively penetrate through the two ground anchor steel bars 2 and are pressed on the support 4, and the length of the support 4 is larger than the interval of the two shoulder pole beams 3.
The working principle of the invention is as follows: the main inventive thought of the product designs a member for improving the lateral stability of the template support frame for applying the existing materials of the construction site and the processing means which can be realized on the construction site so as to meet the construction requirement.
The use of the ground anchor steel bar 2 is to ensure that the ground anchor steel bar can effectively play a role when the support is under tensile force, compared with the use of the ground anchor bolt and other connection mode shoulder pole beams, the ground anchor steel bar can furthest simplify construction procedures and reduce operation difficulty, and because the ground anchor steel bar is required to have the concrete blocks 6 poured under each diagonal brace to erect the support 4, if the ground anchor bolt is used, the situation that the diagonal braces cannot be connected with the support due to position deviation is likely to occur, and the use of the ground anchor steel bar 2 reserves a gap for the support 4, so that the ground anchor steel bar can adjust the position and the diagonal braces to be connected in a certain range of a plane and simultaneously ensure the bearing capacity requirement.
The use of shoulder pole beam 3 then is with the tensile force transmission to ground that ground anchor reinforcing bar 2 cooperation received the support, and the use of shoulder pole beam 3 has guaranteed only to restrict the vertical displacement of support 4, but the free movement adjustment position in the certain within range of horizontal plane, and whether the installation angle position of bracing appears the deviation can realize the installation smoothly, and the power route has been simple and clear, and the atress is effectual.
The use of the support 4 ensures that the load can be well transmitted to the ground no matter the support bears the tensile force or the compressive force, the limiting condition of the construction precision is met, and the installation can be smoothly realized no matter whether the installation angle position of the diagonal brace deviates or not.
In general, all ideas of the invention can be easily realized in terms of construction sites, and the invention has simple procedures and convenient installation.
A manufacturing method of a bowl buckle type formwork support bracket diagonal bracing quick fixing support comprises the following steps:
the first step: four ground anchor steel bars 2 are pre-buried on the ground, the four ground anchor steel bars 2 are enclosed into a rectangle, and the rectangle is fixed on the ground by a concrete block 6;
and a second step of: vertically welding two parallel triangular steel plates on the bottom plate of the support 4, perforating at the same position on the upper parts of the two triangular steel plates, and placing the support 4 on the concrete block 6;
and a third step of: the shoulder pole beam 3 made of scaffold steel pipes passes through two corresponding ground anchor steel bars 2 to be pressed on the support 4;
fourth step: and then the template supporting frame diagonal brace 1 with the lower part provided with holes is hinged with two triangular steel plates of the support 4 by using a fixing bolt 5.
The invention relates to a bowl buckle type formwork support bracket diagonal bracing quick fixing support, which comprises the following application ranges:
working condition one: after the bowl buckle type template support frame is erected, the invention can be used for reinforcing when the rigidity of the template support frame is insufficient or the bearing capacity is insufficient in prepressing, and the bottom of the diagonal brace is erected according to the implementation steps of the invention so as to improve the bearing capacity of the template support frame, which is the most main use condition of the product.
Working condition II: when wind load or vibration load and the like are large in the area where the template support frame is erected, the invention can be designed in during the construction of the template support frame so as to improve the anti-overturning capacity of the template, and simultaneously reduce the number of vertical supports, so that the template support frame not only meets the requirement of bearing capacity, but also improves the economic effect.
