Description
Technical Field
The invention relates to the technical field of assembled steel structures, in particular to a main body connecting structure of an assembled steel structure building and an installation method thereof.
Background
The fabricated steel structure building refers to a fabricated building of which a structural system is composed of steel (structural) members. Compared with the fabricated concrete building, the fabricated steel structure building has the following advantages: no on-site cast-in-place node exists, the installation speed is higher, and the construction quality is easier to ensure; the steel structure is a ductile material, so that the steel structure has better anti-seismic performance; compared with a concrete structure, the steel structure has lighter self weight and lower foundation cost; the steel structure is a recyclable material, so that the steel structure is more environment-friendly; the well-designed steel structure assembly type building has better economy than an assembly type concrete building; the beam column has smaller section, can obtain more usable areas and the like.
Steel construction main part collocation bar whole wallboard, ALC (evaporate and press aerated concrete) board for example is the comparatively general maintenance mode of assembled steel construction at present. The connection mode of the wallboard and the steel structure is usually as follows: every wallboard passes through the connecting piece and is connected with the steel construction, and the connecting piece adopts welded connection with the steel construction, and the connecting piece adopts to wearing the screw rod with the wallboard to be connected. This method has the following problems: the wall boards are installed block by block, the position and the verticality of the wall boards need to be adjusted in the installation process, and the installation precision and the completion effect are determined by the technical level of workers. Wallboard connecting piece passes through the screw rod and connects needs the spot location trompil in the installation, and construction cycle is longer. Welding is needed in the assembling method, and professional technical workers are needed. Furthermore, the connection of the wall panels to the concrete foundation in the prior art typically involves mechanically hammering the tube panels into the wall panels and then securing the tube panels to the concrete foundation by means of the shooting nails. This method has the following problems: the position and the verticality of the wallboard are determined by a measuring method before fixing, the corner of the wallboard is often damaged in the construction process, later-stage repairing is required, and the installation precision and the completion effect are determined by the technical level of workers; welding is needed in the installation method, which is not favorable for the safety requirements of the assembled steel structure for rapidness and high efficiency. The defects in the prior art all lead to that the installation and the connection of the fabricated steel structure building still have great inconvenience, and the construction efficiency still has great promotion space.
In order to solve the defects in the prior art, the grant publication No. CN108824651B proposes a main body connection structure of an assembly type steel structure building and an installation method thereof (hereinafter referred to as "the scheme"), which do not need to perform positioning correction one by one for each wallboard, and can ensure the position accuracy of the assembly type steel structure installed gradually from bottom to top only by ensuring the position accuracy of the first L-shaped connecting member relative to the concrete foundation. The technical effect of the scheme is that all fixed connections in the scheme structure can be realized by adopting bolt connection, the process steps that a large amount of welding construction is still needed in the traditional assembled steel structure are thoroughly abandoned, the whole installation process is simple and convenient, traditional processes such as welding are not needed, the installation efficiency of the assembled steel structure is improved, the installation difficulty is greatly simplified, and the installation speed is improved.
However, the "solution" is that the bottom surface of the wall panel is bonded to the first L-shaped connector by an adhesive, and then fixed to the first L-shaped connector by the second L-shaped connector, so that the wall panel is fixed between the second L-shaped connector and the first L-shaped connector. Because use sticky fixed to it will be little to lead to wallboard fixity fastness to compare in using the fastener to fix like bolt or pin, and different seasons can make the wallboard have certain expansion and contraction moreover, and the interval is very tight between wallboard and the first L type connecting piece, so the clearance is minimum or basically not, thereby will extrude the life-span that is unfavorable for the wallboard to the wallboard when the deformation that wallboard especially high temperature expansion produced. Because there are wallboards of different thickness, need carry out the trompil to concrete foundation or I-steel again after so the interval adjustment between first L type connecting piece and the second L type connecting piece, just so can guarantee to fix through the bolt, however more trompils influence its self bearing performance on concrete foundation or I-steel, secondly the trompil is many also inconvenient, so need do further improvement to the structure of fixed wallboard to the realization can satisfy the wall body of fixed different thickness.
