Description

Strutting arrangement is used in construction of oblique crossing bent cap
Technical Field
The invention relates to the technical field of bent cap construction, in particular to a supporting device for oblique bent cap construction.
Background
The existing capping beam is limited by construction conditions, the existing capping beam needs to be obliquely and alternately arranged with a pier with an oblate or rectangular radial section, and the top of the capping beam needs to be flush with the top of the pier. The oblique crossing arrangement means that the minimum included angle between the length direction of the bent cap and the length direction of the pier is an acute angle, and the bent cap is called an oblique crossing bent cap.
In the construction process of the bent cap, a bent cap bracket is required to be built on the periphery of the pier. Before the bent cap bracket is built, a through hole is preset at a pier body of the pier, which is lower than the oblique bent cap, then a penetrating rod is arranged in the through hole in a penetrating mode, a bracket is fixed on the penetrating rod, then a sand cylinder is arranged on the bracket, and the bracket is installed on the periphery of the pier by taking the sand cylinder as a temporary support.

After the construction of the oblique crossing bent cap 5 is completed, in order to use the supporting device for the construction of the oblique crossing bent cap in a circulating way, the supporting device for the construction of the oblique crossing bent cap is separated from the oblique crossing bent cap 5 after the construction, so that the supporting device for the construction of the oblique crossing bent cap is unloaded. In the unloading process, can be earlier relaxed with first suspension cable 3 and second suspension cable 4, then release articulated department between first support 1 and the second support 2 from the perforation of predetermineeing of pier 6 in advance, then with this articulated department separation, and take out first support 1 or second support 2 from the perforation of predetermineeing of pier 6 in advance, can make first support 1 and the separation of second support 2, and then make first support 1 and second support 2 all separate with skew bent cap 5, then can all separate first suspension cable 3 and second suspension cable 4 with 6 tops of pier, thereby accomplish the whole of strutting arrangement for the construction of skew bent cap.
Because the in-process of unloading, only need to separate the articulated department between first support 1 and the second support 2 and take first support 1 or second support 2 out from the perforation of predetermineeing of pier 6 and can realize the separation of first support 1 and bevel bent cap 5 and realize the separation of second support 2 and bevel bent cap 5, consequently this strutting arrangement for bevel bent cap construction's the process of unloading need not adopt a sand section of thick bamboo, also need not to unload sand to a sand section of thick bamboo many times, more need not observe the sand section of thick bamboo and unload the sand process, consequently also can not receive the sight hindrance of bevel bent cap 5, this strutting arrangement for bevel bent cap construction's the process of unloading is more convenient than a sand section of thick bamboo mode of unloading, and the degree of difficulty is lower, the efficiency of unloading is also higher.
Compared with the prior art, the supporting device for construction of the oblique crossing bent cap provided by the embodiment can form a stable triangular supporting system on the periphery of the pier 6 by penetrating the first support 1 and the second support 2 which are hinged with each other in the through hole preset in the pier 6, connecting the first stay cable 3 between the first support 1 and the top of the pier 6 and connecting the second stay cable 4 between the second support 2 and the top of the pier 6, so that a stable bracket structure can be formed on the periphery of the pier 6, and the construction process of the oblique crossing bent cap 5 can be stably supported. And when unloading this strutting arrangement for bent cap construction that inclines, through with the separation of the articulated department of first support 1 and second support 2 and take out first support 1 or second support 2 from 6 punchholes of pier and can realize this strutting arrangement and the separation of bent cap 5, then can all separate with 6 tops of pier first suspension cable 3 and second suspension cable 4 so that carry out the unloading of whole device, consequently this strutting arrangement for bent cap construction unloads the process and need not adopt a sand section of thick bamboo, the operation is more convenient and the degree of difficulty of unloading is lower.
It should be further noted that, in the supporting device for oblique-crossing bent cap construction provided in this embodiment, the first support 1 and the second support 2 are used as the bracket for oblique-crossing bent cap 5 construction, compared with the existing bent cap construction process in which a through hole needs to be preset on the pier 6 and a through rod needs to be inserted, then a bracket is fixed on the through rod, and then a sand cylinder is installed on the bracket.
In practical application, the first stay cable 3 and the second stay cable 4 can be fixedly connected with the top of the pier 6 in a pre-buried fixing mode respectively, and when the supporting device for the construction of the oblique bent cap beam is disassembled, the first stay cable 3 and the pier 6 need to be separated in a cutting mode, and the second stay cable 4 and the pier 6 need to be separated.
In order to improve the convenience of construction, as shown in fig. 2 and 3, in this embodiment, it is preferable that the supporting device for constructing the diagonal capping beam further includes a fixing structure 7 fixed to the top of the pier 6, and the first stay cable 3 and the second stay cable 4 are connected to the fixing structure 7, respectively.
