Problems solved by technology

[0002] At present, most of the load-bearing bracket products widely used in power (cable) tunnels, power (cable) trenches, subways, urban common trenches, highway and railway bridges, industrial facilities, etc. Short, easy to form magnetic field closed circulation and arc light, high maintenance cost, poor welding construction conditions and other shortcomings; if stainless steel is used, the cost is very high
[0003] Some projects also use glass fiber reinforced unsaturated resin (polyester resin) composite bracket products made by SMC molding process, but this type of product is limited by the molding process, only chopped fiber can be selected as the reinforcement material, and the fiber content Also less, the mechanical properties of the product are low, the brittleness is high, the production efficiency is low, and its long-term weather resistance is also poor
Due to the above defects, the effect of this kind of products in some projects in the past is not satisfactory

preparation example Construction

[0042] Preparation of uprights and support arms:

[0043] Both the column and the support arm are made of thermosetting resin and continuous fiber through pultrusion process.

[0044] The volume content of the continuous fiber in the column and the supporting arm is 50%-85%.

[0045] Thermoset resins include polyurethane, epoxy, phenolic, vinyl, or unsaturated polyester resins; continuous fibers include glass, carbon, aramid, basalt, or hybrid fibers; continuous fibers can be in the form of continuous fiber yarn , felt, cloth or tape.

Embodiment 1

[0047] A combined composite load-bearing bracket, including a column, a connecting piece and a support arm, the support arm is vertically connected to the column through the connecting piece;

[0048] Both the column and the support arm are straight column type; the cross section of the column is U-shaped, the wall thickness is 0.8cm, the cross section of the support arm is rectangular, and the wall thickness is 0.5cm;

[0049]The connector is a reinforced sleeve, the cross section of the column is a U-shaped groove structure, the reinforced sleeve is a ring structure, one end of the support arm is sleeved with the reinforced sleeve and placed in the groove of the column; the support arm It is fixed on the column by the bolts that pass through the column, the reinforcing sleeve and the supporting arm; the reinforcing sleeve and the supporting arm are tightly fitted, and the reinforcing sleeve and the column are tightly fitted;

[0050] When in use, the heavy object is installe...

Embodiment 2

[0057] It is basically the same as Embodiment 1, except that the cross-section of the column and the support arm is C-shaped, the groove width is 5cm, and the wall thickness is 1cm; the connector is a reinforced connector, and the reinforced connector includes a There are two connecting plates on both sides of the connection between the column and the support arm, and the support arm is fixed on the column by the bolts passing through the two connecting plates and the column and the bolts passing through the two connecting plates and the support arm;

[0058] One side of the L-shaped connecting plate is fixed on the surface of the connecting plate through the bolts passing through the two connecting plates and the column, and the other side of the connecting plate is anchored to the building. One side and the other side of the connecting plate refer to the two outer sides perpendicular to each other. ;

[0059] Preparation of columns and brackets (fiber volume content 85%):

Abstract

The invention discloses a combined type composite material bearing support. The combined type composite material bearing support comprises stand columns, connecting pieces and support arms; the support arms are connected to the stand columns through the connecting pieces; and the stand columns and the support arms are made of heat convertible resin and continuous fibers through a pultrusion process. The combined type composite material bearing support manufactured through the continuous long fiber reinforced heat convertible resin and the pultrusion process is disclosed, and the combined type composite material bearing support has the beneficial effects of being high in corrosion resistance, excellent in ageing resistance, high in strength, good in toughness, small in dead load, non-conducting, high in construction efficiency, environment-friendly and the like; in an actual work environment, working condition environmental requirements of high bearing loads, corrosion resistance, inflaming retarding, humidity resisting and the like are met, and the defects that a metal piece is prone to rusting and the later-period maintaining amount is large are overcome; and the structure of the combined type composite material bearing support is in a combined type, flexible disassembling and assembling can be achieved according to needs, and welding is not needed. According to the combined type composite material bearing support, all parts are produced through the pultrusion process; and the production efficiency of the pultrusion process is high, and the fiber content of the product is high and can be 80% or above.
