Abstract

A concrete beam mould board support relates to the concrete beam mould project. A cantilever support is adopted to solve the problems of the bolt beam penetration, complicated component, size adjusting difficulty and working hour waste of the existing beam mould board support. A support is composed of two support arms, a pull rod, a wedged board and a pressure rod. The support arm is composed of two rod welding boards. The pressure rod is resisted against a lower end of the support arm. The pull rod tensions two support arms in a position below the beam bottom mould board. The wedge board is used for connecting and fastening the pull rod and the support arm. A force couple formed from the internal forces of the pull rod and the pressure rod balances the flexural torque of the support arm, simplifies the support component, and thereby realizing the assumption that the working width and height of the beam mould support are flexibly adjusted according to the different size of the concrete beam. The concrete beam mould board support is applicable to the mould board project of clarified water and non-clarified water concrete beam. The simplification of the support structure and the adoption of the wedge structure enlarges the application range of the support, improves the turnover ratio and working quality, saves material and the working hour.

Description

A kind of concrete beam template supports

Technical field

A kind of concrete beam template that the utility model relates to construction work supports.

Background technology

In the beam and slab structure construction of floor, the style that the template that concrete beam is commonly used supports is a lot, roughly is divided into two classes, and the one, split bolt class, the 2nd, support class.

Split bolt class beam form supports and does not form rotatable instrument of week substantially, and the member turnover rate is low, and the number of working processes consumes more; Because of its top split bolt need pass the beam body concrete, the integrality on beam surface is damaged, adopting more and more widely in the building structure of clear-water concrete now, split bolt class beam form support technology is replaced by support class beam form support technology.

Style and size adjustment mode thereof that support class beam form supports are more, but aspect the support size adjusting of deck-molding direction, still lack technical measures efficiently, and the shared property of regulating parts is poor, causes used adjusting component specification many, and complex operation; The shortcoming that also has a general character is promptly used bolt or is sold fastening support directly to households at the fastening node that supports, and because of the tolerance clearance of connector causes fastening weak effect to template, beam angle spillage takes place easily.

Summary of the invention

For the bolt that solves the support of split bolt class beam form is worn beam and is wasted problem man-hour, also solve simultaneously the fastening shortcoming problem that size adjustment efficient is low and beam forms supports that support class beam form supports, the utility model provides a kind of new concrete beam template to support, can simplify supporting member, improve service efficiency, form erecting operation efficient and quality of concrete members that beam form supports, reduce cost.The utility model is in the form work engineering of the clear water of beam and slab structure and non-clear-water concrete beam, and is all applicable.

The technical scheme that the utility model technical solution problem is adopted is:

Form a cover and support by 2 support arms and 1 pull bar and 1 wedge thereof, 1 depression bar.

Every support arm is made of 1 rod member or is made of 2 rod member weldering batten plates, 1 baffle plate is respectively welded towards template one side in lower end at the support arm rod member, in the beam form in cross section commonly used supports, make the support arm rod member with the cold bending thin wall rectangular steel pipe, in large-scale beam form supported, available miniature triangular truss replaced rectangular steel pipe; Pull bar is made of 1 rod member or 2 rod member welded attachments, the one end is a fixed end, the other end is for regulating the fastening end, fixed end welding rod end plate, a plurality of adjusting mounting plates are welded by the size-spacing of required adjusting in the adjusting fastening end, regulate the right-angled trapezium that is shaped as of mounting plate, and its hypotenuse is towards pull bar end plate direction, wedge is that the top is wide, the board-like wedge tool of the right-angled trapezium of narrow base, and its hypotenuse gradient equates with the hypotenuse gradient of regulating mounting plate; Depression bar is a straight-bar, and the one end is a fixed end, and the other end is the adjustable side, fixed end welding depression bar end plate, and a plurality of adjusting top boards are welded by the size-spacing of required adjusting in the adjustable side.The structure that supports is: two support arms, the two side templates back of the body that reclines respectively is distracted, the end plate of depression bar and adjusting top board are replaced the lower end of two support arms respectively, pull bar is worn in beam bottom board plate hypodermis position and is drawn two support arms, the adjusting mounting plate of pull bar is positioned at the support arm outside, the wedge wedge is in regulating between mounting plate and the support arm, connect and fastening pull rod and support arm, after the wedging, the hypotenuse of wedge one side and the parallel contact in inclined-plane of regulating mounting plate, long limit, right angle one side and support arm two the rod member wall is parallel contacts.

The beneficial effects of the utility model are:

1. adjusting parts and the support diagonal brace of wearing beam, the support of support class beam form that split bolt class beam form supports have been cancelled, the structure types of support and the stress characteristic of member have been changed, the work of support arm cantilever, the moment of flexure of the equilibrium of couples support arm that forms with pull bar internal force and depression bar internal force, supporting member is simplified, saved material.

2. the change of support structure, the nimble adjusting beam form of the different size support works width and the imagination highly that have effectively realized pressing concrete beam enlarge the scope of application of support, and all transfer efficients improve.Regulate the working width that beam supports with the adjusting mounting plate of pull bar and the adjusting top board of depression bar; Pull bar is located at beam bottom board plate hypodermis position, accompanys or follow the concrete depth of beam and regulates the working depth that beam supports.

3. use the wedge connection at fastening node, replaced bolt commonly used and connected, effectively realize location and clamping, stopped the solid not tight phenomenon that causes because of the connector tolerance clearance support and template.

4. because of the simplification of support structure replaces bolt connection commonly used with being connected with wedge, make simple operation, save the number of working processes.
