The present invention discloses a construction method of a section steel column for a high-rise building section steel concrete combination structure. The section steel column comprises a plurality of column sections, wherein the column sections are sequentially connected from bottom to top, an interface position of two optionally adjacent column sections is provided with an inner sleeve interface, and an outer side wall of a connection position of the two adjacent column sections is provided with a buckle fixation type assembly. The construction method comprises that: the insert-connection type initial positioning of the two adjacent column sections is achieved through the inner sleeve interface; the cross extending line and the buckle fixation type assembly are combined to carry out positioning correction on the column; a scale measurement method is adopted to carry out column scale height adjustment; and the cross extending line and the buckle fixation type assembly are combined to carry out verticality correction on the full length of the column sections. With the section steel column of the present invention, the model of one construction interface in each floor of the traditional section steel column can be increased to the model of one construction interface in every two floors or three floors, such that more than half of the construction interfaces of the section steel column can be saved, the probability of deviation error due to construction interface operation can be greatly reduced, and the guarantee degree of installation quality can be improved.

The invention belongs to the field of rectangular column mold pouring, particularly discloses a novel tool type rectangular column mold reinforcing device, and aims to solve the technical problem of providing a novel tool type rectangular column mold reinforcing device which is simple in structure, convenient to use, adjustable in section and recyclable. The novel tool type rectangular column mold reinforcing device comprises two I-shaped rod pieces and two II-shaped rod pieces, each of two end portions of each I-shaped rod piece is provided with a first limiting and adjusting device, second limiting and adjusting devices are arranged on the II-shaped rod pieces, the two I-shaped rod pieces are parallelly arranged on two sides of a rectangular column mold, the first limiting and adjusting devices on the same sides of the two I-shaped rod pieces are connected via the II-shaped rod pieces and used for adjusting distance between the II-shaped rod pieces, and the second limiting and adjusting devices are used for adjusting the length of the II-shaped rod pieces and the distance between the two I-shaped rod pieces. The novel tool type rectangular column mold reinforcing device is simple to manufacture, convenient to use and recyclable while serving as a tool type product to be applied to rectangular column mold reinforcing, so that capital investment can be reduced and a utilization rate of materials is increased.

The invention relates to a structure and a construction method of a cast-in-style welded steel frame composite concrete shear wall. The structure comprises an indoor concrete layer, an outdoor concrete layer and a wire frame insulation sandwich board. The wire frane insulation sandwich board is coated between the indoor concrete layer and the outdoor concrete layer. At least two rectangular and groove-typed cantilever holes are arranged at the top of the sandwich board, and each cantilever hole is provided with a U-shaped cantilever anchor bar which penetrates through the sandwich board and a floor slab to be fixedly connected with the floor slab. The construction method includes site preparation work, binding of load-bearing steel bars of a wall body and edge member steel bars, custom processing of the sandwich boards, installation of the sandwich boards, pavement of template positioning pieces and wall bushings, fixation of water and electric pipes inside the wall body, binding of ordinary blocks on both sides of the wall body steel bars, erecting of the templates, pouring of the concrete, removing of the templates and concrete curing. Since a series of composite wall construction methods are adopted, problems existing in the prior art are solved, and a composite heat preservation technology is improved.

The invention discloses a machining process of an internal combustion engine radiator. The machining process comprises the following steps that S1, materials are selected; S2, blanking is carried out,and a water chamber and a clamping part at the lower end are integrally extruded and formed; S3, a core body is assembled; S4, the core body and the water chamber are assembled; S5, the core body andthe water chamber are compressed, and the clamping part and a main sheet in the clamping part are compressed through an extrusion device; S6, an end plate of the water chamber is assembled; S7, a reinforcing plate is assembled; and S8, brazing forming is carried out. According to the machining process of the internal combustion engine radiator, the welding quality can be improved, the water testing and pressing qualification rate is increased, and the one-time pressing qualification rate reaches 98% or above; the assembling efficiency of the aluminum water chamber and the main sheet is improved, and the forming period of the radiator is shortened; the automation level is improved, manual operation is reduced, and the yield of radiator finished products is not limited by argon arc weldingworkers; and compared with other processes, the appearance of the product is more attractive.

The invention discloses a wall post formwork blocking and leveling device and a construction method thereof. The device includes: a blocking piece for blocking the root of the formwork of the wall column, including a positioning formwork, a vertical wooden square and a horizontal wooden square. Plywood; adjustable top bracket, used to support the wall column formwork and adjust its height, including: base, support rod vertically fixed on the base, and support member threaded on the top of the support rod, the base is pressed on the upper surface of the lower laminated board , the supports rest on the bottom of the horizontal wooden squares. The present invention uses the sealing piece to block the root of the wall column formwork and at the same time adopts the adjustable jack to adjust the height of the support member, not only can the root of the wall column formwork be sealed tightly, but also the top of the wall column formwork can be adjusted to a horizontal state conveniently. It not only ensures the construction quality, but also ensures the cross-sectional size of the concrete structure.
