Hydraulic creeping formwork system and creeping formwork construction method

The invention provides a hydraulic creeping formwork system and a creeping formwork construction method. The invention is characterized in that a climbing system is composed of four machine positions and a creeping formwork device attached to a wall surface, wherein machine positions are arranged on a transverse bridge edge; a formwork, a formwork moving bracket, a working platform, a hydraulic power device, a hydraulic platform and a decorative platform are arranged from top to bottom at the machine position side; on a longitudinal bridge edge, no machine position is arranged and only the formwork, the formwork moving bracket, the working platform and a man passageway connected to a climbing face hydraulic platform are mounted; and in a climbing process, the formwork and the working platform on the longitudinal bridge edge are driven to climb together with four sides by the four machine positions on the transverse bridge edge. The hydraulic creeping formwork system overcomes the defects of other hydraulic creeping formwork devices that mounting and dismounting are inconvenient and quantity of used hydraulic creeping formwork devices is large. The hydraulic creeping formwork system is simple in integral structure, is conveniently maintained and is conveniently mounted and dismounted.

Unilateral formwork erecting system of cast-in-site concrete arc outer wall body and construction method thereof

The invention discloses a unilateral formwork erecting system of a cast-in-site concrete arc outer wall body and a construction method thereof. The construction method comprises the following construction steps: 1. setting an embedded part on a concrete floor slab below an arc wall body which is not cast; 2. pre-splicing an arc wall body formwork; 3. pre-splicing and mounting a unilateral support frame on site and fastening the unilateral support frame and the embedded part; 4. connecting the unilateral support frame and the arc wall body formwork; 5. setting up a scaffold required by the unilateral support frame; 6. adjusting, reinforcing and checking various parts; 7. casting arc wall body concrete between the arc wall body formwork and an arc outer wall body of an adjacent building; and 8. detaching the formwork after the concrete strength meets the specification requirement. The invention has the advantages of greatly shortening the construction period, saving labor force, reducing the construction cost and meeting the requirement of structural construction quality and is particularly applicable for wall body construction of automobile ramps, stadiums and other large-scale public buildings with arc structures.

Early-removal formwork system for concreting of constructions comprising beams, plates and columns

An early-stripping formwork system for concreting of constructions comprising beams, slab and columns comprises several rectangular standard formworks (1), props with multiple early-stripping support mechanisms (2), several filler beams (3) and filler panels. The standard formwork (1) consists of a panel (11) and a formwork frame (12), and the formwork frame (12) is provided with L-shaped corners (121) at its four corners. Each of the early-stripping prop (2) consists of an upper support inner tube (21) and a lower support tube (22) which form a telescopic connection, a rectangular head plate (23) is disposed at the top end of the upper support inner tube (21), one corner of the head plate (23) fits an internal corner of any one of the L-shaped corners (121) on the formwork frame (12). A load-releasing mechanism (24) is connected between the upper support inner tube (21) and the lower support outer tube (22). An early stripping mechanism (25) for early stripping of the standard formwork (1) is disposed on the upper support inner tube (21), short posts (251) for supporting the formwork frame (12) are disposed at four corners of the early stripping mechanism (25), and a structure for preventing the formwork frame (12) from slipping outwards is formed between the short post (251) and the L-shaped corner (121). The formwork frame (12), the filler panel, the filler beam (3), and a bridge beam (4) may be all in a detachable combined structure. In the formwork system, transport and storage of the formwork are convenient, and manufacturing cost is reduced.

System support assembly

A system support assembly comprises a pair of substantially parallel footer forms, insulated concrete forms, footer form base saddles, a poly form saddle assembly and first and second vertical stabilizers. The footer form base saddle may be generally u-shaped and is driven into the ground forming two substantially parallel areas. Each footer form is placed within the row formed by the footer form base saddles such that a cavity is defined therebetween which will ultimately form the footer of the foundation. The poly form saddle assemble comprises a poly form saddle and fasteners. The poly form saddle may also be generally u-shaped and is placed over both footer forms, thus straddling the same. The poly form saddle may then be secured with corresponding fasteners. The insulated concrete forms are placed side by side and are stacked upward, such that a wall is formed. A first poly form vertical stabilizer is placed over the wall and operatively connected to the footer form base saddle. More insulated concrete forms are stacked to complete the wall. The second poly form vertical stabilizer may then be placed, preferably laterally spaced from the first poly from vertical stabilizer. The second poly form vertical stabilizer is also operatively connected to the footer form base saddle. Then, the concrete is poured into the insulated concrete forms such that the foundation wall and footers are poured and cured at one time.
