Horse Construction business range tend to all over the world and service for thousands clients with products, technical,construction specialized guidance, and we witness the Chinese reinfocing brand's togther with them.
Slab strengthening, column strengthening, beam strengthening, wall strengthening, seismic strengthening.
2020-01-13 06:29Concrete beams and slab members are the most widely used structural members in the current project. The flexural members of beams and slabs are strengthened by insufficient bearing capacity, including two aspects of the positive and inclined section.
2020-01-13 06:31Enlarging section reinforcement method Application: Reinforcement for flexural and compressive members of reinforced concrete(RC) structures.
2020-01-13 06:33Identify the nature of cracks; Ensure structural safety; Ensure durability;Prevent unnecessary damage; Improve the conditions of structural use, eliminate the factors causing cracks; Meet the design requirements and comply with the relevant provisions of the standard specification.

2020-01-13 06:51The key point of crack repair works is to design according to the types of cracks, determine the repair materials, repair methods and repair time.
2020-01-13 06:53Preventive measure of structural strengthening: CFRP strengthening, steel plate strengthening, post installed anchoring.
2020-01-13 06:55Post installed anchor with chemical anchoring adhesive is a simple and effective connection and anchorage technique for concrete structures, which can be implanted in ordinary steel and bolt anchorage. It is now widely used in strengthening and rebuilding of buildings.
2020-01-13 06:57Strengthening and rehabilitation of reinforced concrete(RC) member with opening by carbon fiber reinfroced polymer(CFRP) and bonded steel plate.
2020-01-13 07:00Strengthening of beams and slabs with steel plate:1.substrate surface clean; 2.scribe line ro setting out; 3.anchoring; 4.plate surface preparing; 5.bonding steel plate with the structural adhesive; 6.maintaince; 7.checking; 8.protection coating
2020-01-13 07:02Beam thickness strengthening method must ensure that the new and old concrete has higher bond strength. The main points are as follows: the base course of the original component joint surface should be solid, the surface is rough and clean, the shrinkage stress of the new cast concrete is small, and the bond performance is good.

2020-01-13 07:05Common structural strengthening method for reinforced concrete structure:Enlarging section reinforcement method; Steel plate strengthening; FRP composite strengthening
2020-01-13 07:06There are many problems with existing bridge, for example, cracks, load increase, steel corrosions. So we need to strengthening and repair the bridge with structural strengthening system.
2020-01-13 07:08Although there are many ways to strengthen the bridge and improve the bearing capacity of the bridge, the basic principles are all the same, and all of them follow the basic principle of mechanics. From the angle of external factors and internal conditions of bridge structure to strengthening for improving the bearing capacity.
2020-01-13 07:09According to the investigation data, the cause of structure cracking in engineering practice is about 80% of the cracks caused by "deformation" or cracks caused by "deformation" as the main factor, and about 20% of the cracks caused by the "load" factors.
2020-01-13 07:10Structural strengthening is to reinforce the original stressed structure, so as to meet the new requirements and safety, and save costs and reduce investment.
