Description
Technical field
The utility model relates to the bracing or strutting arrangement in a kind of construction work, refers to a kind of prestressed bracing arrangement especially.
Background technology
Often use bracing or strutting arrangement in the work progress of construction work, bracing or strutting arrangement at present commonly used has the scaffold of setting up to support and jack adds the combined support of steel column.
Wherein, scaffold supports and belongs to passive bracing or strutting arrangement, promptly owing to after the structure stress distortion load is imposed on this device, it is just played a supporting role, this kind support is mainly used in the wet trade process of civil engineering structure, or the structural element that goes wrong is carried out protectiveness support, prevent aspects such as the further expansion of problem, but scaffold supports and can't apply support force accurately to works;
The combined support that jack adds steel column belongs to the Active support device, promptly with the support force effect structurally by jack, this kind bracing or strutting arrangement can be used in the work such as off-load of structural strengthening, but the combined support that jack adds steel column is in accuracy and apply aspect the degree of controllability in the process relatively poor, the support force error that promptly provides is very big, and work progress is not easy to operate; And the jack combined support that adds steel column structure is applied finish support force after, the continuous stability of this support force is difficult to control, deforms at strong point place as structure, support force can take place significantly to slacken.After this situation of generation, if will append support force at the former strong point, how accurately calculating is appended the size of power and how to be realized applying this power and all has very big difficulty.
The utility model content
The purpose of this utility model provides a kind of support force that precision height, good stability can be provided supported structure, and constructing operation is easy to prestressed bracing arrangement.
For achieving the above object, the utility model is taked following design scheme:
A kind of prestressed bracing arrangement is characterized in that, it comprises:
A support frame of forming by base plate, left plate, right plate and top board, the both sides of described left plate and right plate vertically are provided with some junction plates that are connected described left plate and right plate, described top board respectively is provided with a through hole for four jiaos, and described top board middle part is provided with a macropore;
A steel column that is positioned at support frame inside, described steel column is arranged in the macropore of the top board of described support frame, both sides, described steel column lower end are fixedly connected with two steel column foots that are positioned at the described support frame outside by the steel column base plate, the two ends of each steel column foot are equipped with a prestressing force steel hinge line respectively, and the lower end of the described prestressing force steel hinge line of each root is fixedly connected with an Extrusion anchor ground tackle that is used to support described steel column foot; The upper end of four prestressing force steel hinge lines pass respectively described support frame top board four through holes and fixedly connected with the intermediate plate ground tackle.
The top of described steel column is fixedly connected with the gripper shoe of an area greater than described steel column top board area, is fixedly connected with stiffener between described gripper shoe bottom and the described steel column.
The utility model has the advantages that: the utility model is owing to adopt above design scheme, jack pair prestress wire by the support frame top carries out stretch-draw generation stretching force, this power is delivered to steel column foot by prestress wire, pass to steel column by the steel column base plate again, steel column is passed to power supported structure at last.The stretching force on support frame top is passed to ground by support frame.The utility model prestressed bracing arrangement utilizes the prestressing force steel hinge line to provide numerical value accurate support force for prestressed bracing arrangement, and support device structure is simple, good stability, constructing operation are simple and easy.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of prestressed bracing arrangement of the utility model is characterized in that it comprises:
A support frame of forming by base plate 1, left plate 2, right plate 3 and top board 4, the both sides of left plate 2 and right plate 3 vertically are provided with some junction plates 5 that are connected left plate 2 and right plate 3, top board respectively is provided with a through hole 6 for 4 four jiaos, and top board 4 middle parts are provided with a macropore 7;
A steel column 8 that is positioned at support frame inside, steel column 8 is arranged in the macropore 7 of the top board of support frame, both sides, steel column 8 lower end are fixedly connected with two steel column foots 10 that are positioned at the support frame outside by steel column base plate 9, the two ends of each steel column foot 10 are equipped with a prestressing force steel hinge line 11 respectively, and the lower end of each root prestressing force steel hinge line 11 is fixedly connected with an Extrusion anchor ground tackle 12 that is used to support steel column foot 10; The upper end of four prestressing force steel hinge lines 11 pass respectively support frame top board 4 four through holes 6 and fixedly connected with intermediate plate ground tackle 13.
The top of steel column 8 is fixedly connected with the gripper shoe 16 of an area greater than steel column top board area, is fixedly connected with stiffener 14 between gripper shoe 16 bottoms and the steel column 8.
Groundwork step of the present utility model and principle are as follows:
1, calculates the stretching force of every prestress wire 11 according to the needed support force of supported structure;
2, according to the intensity of stretching force and prestress wire 11, the stretch-draw length that modulus of elasticity calculates prestress wire 11;
3, calculate steel column 8 according to support force and support the axial compression distortion of tank bracket under the support force effect, and with this distortion numerical value all add calculate in the 2nd step stretch-draw length, as final stretch-draw length;
4, the utility model bracing or strutting arrangement assembling is finished, carried out stretch-draw (can be divided into several steps finish stretch-draw) by 15 pairs of prestress wires of jack 11.
5, to finish be after support force applies in stretch-draw, adopt the pulling force of vibratory string method at-once monitor prestress wire 11, the pulling force sum of all prestress wires 11 is compared with the required support force of supported structure, judge whether support force slackens, thereby determine whether to take stretch-draw measure once more, guarantee the stable of support force.
