Abstract

An attached truss type concrete wall form support relates to concrete wall form engineering, solves the problem of material and working hour waste as the conventional truss type support is small in rigidity and requires many through-wall pull rods, and includes two trusses, four truss support rods and two sets of external connection tool type through-wall pull rods, wherein truss stabilizing rods, back ridges and the truss are respectively and mutually connected to form a truss plane external stabilizing system, and the truss and the wall form are fastened through the external connection tool type through-wall pull rods, tool type external connection joints can be used in a turnover manner. According to the invention, a truss plane external support member is simplified, the support rigidity is enhanced, the through-wall pull rods are reduced, and the wall form support is applied to larger concrete wall bodies; in addition, the support rigidity is high, the members can be simplified and the through-wall pull rods are few, so that the support efficiency and the working quality are improved, material and operation labor hour are saved.

Description

A kind of truss-like concrete wall template that adheres to supports

Technical field

A kind of concrete wall template that the present invention relates to construction work supports.

Background technology

In the concrete wall structure construction of all kinds of buildings, structure, the mode that wall form commonly used supports is to use two steel pipes to support, and uses wall-crossing opposite-drawing bolt fastening.

Due to the stiffness limits that is subjected to steel pipe, the spacing of the wall-crossing opposite-drawing bolt on the spacing that supports and per pass support is all less, need to drop into a large amount of man-hours and material on the operation of fastening support, especially on the bodies of wall such as the basement that the antiseepage requirement is arranged, pond, can only use expendable water-stopping tie bolt through walls, construction cost is higher.And,, because through-wall bolt arranges that density is high, cause also that post processing workload after form removal is large and that the probability of wall leakage occurs because constructing operation is improper is high.

Summary of the invention

In order to solve the expensive and potential quality problems of concrete wall template steel pipe support, the invention provides a kind of new concrete wall template supports, can reduce clamp structure, improve service efficiency, template construction operating efficiency and quality of concrete members that the wall mould supports, reduce costs.The present invention is applicable to the larger area concrete wall template construction of all kinds of buildings, structure.

The technical scheme that technical solution problem of the present invention adopts is:

Pull bar is formed one overlap and adhere to Formwork Support for External by 2 truss structures, 4 truss stability bars and 2 cover external tool formulas are through walls; Utilize back cord and truss, truss stability bar to interconnect respectively, form stabilising system outside the truss plane, through walls to the fastening truss of pull bar and wall form with the external tool formula.truss is by conventional pattern truss and adhere to connector and form, adhere to connector and be and respectively establish 1 at the pricncipal rafter two-end part perpendicular to the template direction and be used for connecting the connecting hole of back cord, at the corresponding position of lower chord, perpendicular to lower edge, respectively establish 1 junction plate that is used for the truss frame for connecting stabiliser bar, the junction plate root is established square opening, and the truss two ends of winding up is closed cross-section, 1 connecting hole that connects back cord is established in the upper end of truss stability bar, and the square pin of 1 truss frame for connecting lower edge is established in lower end, stays the rotation-limited gap between the square opening of square pin and truss lower edge junction plate, the external tool formula is through walls to be formed the external joint of pull bar by 1 joint bar through walls and 2 joint tool-types, bar through walls is straight-bar, the bar middle part adds seal plate, connecting thread is established at two ends, the external joint order of every joint is by 1 branch sleeve, 1 sleeve connecting rod, 2 outside links, 1 wedge and 1 wheel chock form, the afterbody clamping welding wheel chock of 2 outside links, stem clamping welded sleeve connecting rod, middle part is the wedge working space, the logical internal thread of establishing of branch sleeve, the stem silk female connector cylinder of sleeve connecting rod, wheel chock is right-angled trapezium, top margin up, hypotenuse is towards template, wedge is right-angled trapezium, the hypotenuse gradient is identical with the wheel chock hypotenuse gradient.The structure that adheres to Formwork Support for External is: the lower end square pin of truss stability bar is inserted the square opening of lower edge junction plate, turn to dead point and be fixedly connected with truss stability bar and truss lower edge, be connected and fixed respectively truss wind up upper end and back cord with back cord, truss stability bar with nail in relevant position, form system outside leg-of-mutton truss plane; The sleeve of the external tool formula 2 external joints of joint to pull bar through walls silk respectively connects the two ends of bar through walls, the termination of winding up of adjacent truss is at the external tool formula overlap joint up and down to pull bar through walls, the wheel chock of external joint is positioned at the wind up outside of termination of truss, the wedge top margin down, wedging is winded up between termination in wheel chock and truss, fastening truss and wall form, after wedging, wind up parallel contact of rod member wall of termination of the hypotenuse of wedge one side and the parallel contact in the inclined-plane of wheel chock, long limit, right angle one side and two truss structures.

The invention has the beneficial effects as follows:

1. bring into play the high stiffness characteristics of truss, load-carrying efficiency is high, and the adjustable range of support interval is large, and the post processing workload after form removal reduces; Arrange straining solid member in 2 freely-supported modes, and adjacent truss shares a supporting-point with overlapping mode, reduces through walls to straining solid member, saving material and the number of working processes.

2. utilize back cord to make stabilizing member, adopt the truss stability bar to be connected with truss with back cord, the dead point of employing square opening pin is in clamping connection the truss lower edge, realizes the truss lateral stability, construct simple and direct, saving member, reliable operation, easy and simple to handle.

3. employing external tool formula is through walls replaces traditional monolithic split bolt to pull bar, has both adapted to the fastening high strength requirement of truss support, has reduced drawing the disposable material consumption of member because external part becomes tool-type again; Adopt wedging mode fastening support, fastening reliable for effect, easy and simple to handle, save man-hour.
