Embodiment Construction

[0017] The implementation of the present invention will be further described below in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0018] Such as figure 1 As shown, the frame-type combined support system includes lattice column 1; support 2; main structure 4 and support 3. Under the original support 2, support replacement 3 is respectively arranged to form a frame-type combined support replacement.

[0019] Such as Figure 2 to Figure 5 As shown, the construction steps of the frame-type combined support system are as follows: ...

Abstract

The invention relates to a frame type combined support-replacing system and a construction method thereof. The frame type combined support-replacing system comprises lattice columns, supports, a main body structure and replacing supports, wherein the replacing supports are respectively arranged below the original supports, thereby forming a frame type combined replacing support. The frame type combined support-replacing system is a novel support-replacing system in which the newly-built replacing supports are combined with the original part of supports to form the frame type combined support to together resist a structural lateral force. The frame type combined support-replacing system utilizes the original part of supports, thereby not only reducing the construction workload of the newly-built supports and also saving the construction period for removing the original supports. The original supports and the newly-built supports bear force in a combined manner, so that the rigidity and the stability of the replacing supports are further increased.

Description

technical field [0001] The invention relates to a frame-type combined bracing system and construction method, in particular to a bracing construction method suitable for the construction of underground large space structures in core urban areas. Background technique [0002] During the construction of conventional underground structures, due to the lack of floor slabs and small space spans, only reinforced concrete beams or profiled steel beams can be constructed at the corresponding parts to meet the support requirements. In the construction of underground large space structures, the missing area of ​​the structural floor is large, the number of missing floors is large, and the space span is large. It is difficult to ensure the reasonable stress and construction safety of the replacement brace from the perspectives of strength, stiffness and stability. The construction of multi-channel beam type support is not only troublesome in construction, but also prolongs the construc...
