Description

The standard knot of assembled lattice support bracket

Technical field

The utility model relates to a kind of support, particularly is applied to the assembling standard knot of the realm of building construction support.When monolithic reinforced concrete structure is constructed, need set up falsework; When Steel Structure Installation, need set up independent support or operating platform.

Background technology

When the time setting up falsework and Steel Structure Installation, the monolithic reinforced concrete structure construction sets up independent support or operating platform is a requisite action in the building operations; Only on various supports, support or platform, just can finish the cast-in-place work of reinforced concrete structure and the installation work of steel work, this work is in the building operations one very important step, the quality that support, support or platform are set up quality directly has influence on construction quality, safety, duration and cost, therefore, construction administrative service divisions at different levels and each unit in charge of construction pay attention to the work of setting up of support, support or platform very much.Set up traditional support, support or platform two kinds of patterns are generally arranged: one is to use scaffolding steel pipe to set up, this is the most frequently used a kind of method, this method has advantage very flexibly, but this method also has shortcoming, is mainly reflected in the following aspects: 1. center line of the bar off-centre is comparatively serious.Connecting by fastener between this rod member of setting up pattern, is a kind of relation of overlap joint between rod member and the rod member, and the eccentric axis amount of rod member is at least at 1 times more than the caliber; 2. the mode of transfer force degree of safety is low.Be to come transmission internal force between this rod member of setting up pattern by the frictional force between fastener and the rod member, and the size of frictional force is relevant with the size and the friction factor between the contact surface of fastener screwing force, this has very big randomness with regard to the size that has determined frictional force, and the mode of transfer force degree of safety is low.3. verticality is difficult to guarantee.The standard section of scaffolding steel pipe is of a size of 48 * 3.5, and less because of the cross section, therefore bending easily in application, also is difficult to guarantee the verticality of support.4. installation, dismounting and transport amount are big.Because of the bearing capacity of single pole is lower, bear same external load, just need set up more pole, dismounting and transport amount also just increase accordingly.Another sets up pattern is to make specially of shaped steel.This pattern can overcome above-mentioned shortcoming, but following shortcoming is also arranged: 1. do not carry out systematicness and consider, so support mostly is disposable consumption greatly, cost is higher.2. use at every turn need specialized designs, make specially, application is trouble very, and correspondence is very high with personnel's technical level requirement, is difficult to promote.

Summary of the invention

The purpose of this utility model provide a kind of load-bearing rod member vertical height, power transmission reliably and transport the standard knot of light assembled lattice support bracket.

The purpose of this utility model realizes by following proposal: be the shaped as frame skeleton that is connected and composed by bolt with elementary cell, described elementary cell is by vertical load-bearing steel pipe, connect steel pipe, connect steel loop, connect steel plate A and be connected steel plate B composition, the two ends of load-bearing steel pipe are welded to connect steel loop respectively, on the load-bearing steel pipe that connects steel loop near two, weld connection steel pipe perpendicular and in same side respectively, and weld connection steel plate A perpendicular and in another side equally, weld and be connected the connection steel plate B of steel plate A pairing connection respectively at the other end of two connection steel pipes.

Two of described elementary cells connect the fixedly connected steel pipe that welding intersects between the steel pipe.The connection steel pipe at described connection steel plate B place with fixedly connected steel pipe two links respectively welded closure strengthen steel plates.Described shaped as frame skeleton is to be connected and composed by bolt by 3 or 4 or 5 elementary cells.

Each lattice support bracket height as required is made of identical standard knot stack, connects by bolt between the standard knot.

The utlity model has following advantage:

1. there is not the eccentric axis problem, overcome the influence of additional bending moment; 2. mode of transfer force is bolt and weld seam power transmission, and power transmission is reliable, the degree of safety height; 3. verticality guarantees easily, because elementary cell all adopts the mould customization in factory, and the bottom is provided with universal self-balancing adjustable seats, and the verticality precision is easy to guarantee; 4. installation, dismounting and transport amount are little.Higher because of lattice rack bearing power, under the situation of bearing same load, it is less to set up the lattice support, and dismounting and transport amount are also just less accordingly; 5. installation, dismounting and convenient transportation.Be bolt between the elementary cell and between the standard knot and connect, it is very convenient to install, dismantle; Because the elementary cell of lattice support is plane structure, transportation time space utilization rate height transports very convenient; 6. cost is lower.Because the lattice support bracket tool can repeatedly have enough to meet the need application, its manufacturing cost can be shared equally in each application, and cost is relatively low.7. not high to operating personnel's technical requirements.Because lattice support bracket is to be assembled by the duplicate fashion-part of shape size when using, operating personnel only need it is assembled, and do not need very high-tech level.In a word, can carry out setting up and removing of support, support or platform fast, safely, easily, and very economical, and use cost only accounts for 30% of conventional stent.
