Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated components, in particular to a prefabricated UHPC component sleeve. Background Art

[0002] Ultra-high performance concrete, referred to as UHPC (Ultra-High Performance Concrete), is the most innovative cement-based engineering material in the past thirty years, achieving a great leap in the performance of engineering materials. UHPC is the most durable engineering material. The mechanical properties of properly reinforced UHPC are close to those of steel structures. At the same time, UHPC has excellent wear resistance and explosion resistance. Therefore, UHPC is particularly suitable for large-span bridges, explosion-proof structures (military projects, bank vaults, etc.) and thin-walled structures, as well as for use in highly abrasive and highly corrosive environments.

[0003] In the prior art, back-bolt connection, slot connection, pin connection and sheet connection are generally used for prefabricated UHPC components. The back-bolt connection method has the problem that when the structure thickness is required to be thicker, the quality is difficult to control and the concentrated stress is too large. The slot connection method cannot use universal plates and needs to customize UHPC according to the size. The pin connection and sheet connection have the problem of drilling and slotting in the UHPC plate. In order to solve the above problems, a prefabricated UHPC component sleeve is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated UHPC component sleeve in order to solve the above problems.

[0005] The technical solution adopted by the utility model is as follows: a prefabricated UHPC component sleeve, comprising:

[0007] A clamping member is arranged on the outer wall of the connecting portion, a clamping slot matching the connecting portion is opened on the front side of the clamping member, and a connecting slot is opened on the rear side of the clamping member;

[0008] The fixing piece is fixedly installed in the connection groove by means of bolts, a connection block is integrally arranged on the front side of the fixing piece, and an anchor rod is arranged inside the fixing piece.

[0009] Through the above technical solution, when installing the UHPC component, the clamp is first fixed to the outer wall of the connection part through the clamping groove on the front side thereof. After the fixing is completed, the anchor rod on the front side of the fixing part is fixed to the inside of the building wall to be installed. After the fixing part is installed, the connecting block on the front side of the fixing part is inserted into the connecting groove on the rear side of the clamp, so as to install the UHPC component body. The problem of excessive concentrated stress is solved by fixing with multiple clamps. At the same time, the setting of the clamp in conjunction with the connection part is adopted, and no additional drilling and customization are required.

[0010] In a preferred embodiment, locking holes are provided at both upper and lower ends of the clamping member on one side close to the connecting groove.

[0011] Through the above technical solution, when the connecting block enters the connecting groove, the bolt locks the two through the locking hole.

[0012] In a preferred embodiment, an adjustment groove is provided inside the connection block, and one side of the anchor rod is located inside the adjustment groove.

[0013] Through the above technical solution, the anchor rod can be easily adjusted through the adjustment slot.

[0014] In a preferred embodiment, the connecting portion and the slot are both dovetail structures.

[0015] Through the above technical solution, the structure has the advantages of high-strength joint, high degree of freedom, easy maintenance and strong tensile strength.

[0016] In a preferred embodiment, the clamping member and the fixing member are both made of aluminum alloy.

[0017] In a preferred embodiment, the inner wall of the slot is provided with friction patterns.
