Description

Technical Field

[0001] This invention provides a mortise and tenon joint curtain wall connection method, which relates to the technical field of curtain wall connection methods. Background Technology

[0002] Traditionally, the connection between embedded parts and the curtain wall frame is achieved by fixing the frame with expansion bolts or chemical anchors and then welding them together. This method has the following problems:

[0003] First, the difficulty in determining whether expansion bolts and nuts are tightened, as well as the effects of mechanical vibrations on site, can cause the bolts and nuts to loosen.

[0004] II. The impact of operational procedures during the construction of chemical anchors on the strength of chemical anchors:

[0005] 1. The cleaning of dust inside the hole has a significant impact on the performance of chemical anchors. If the performance of chemical anchors is 100% under standard cleaning, the performance is only 70% when a backup vacuum cleaner is used; only 50% when a backup brush is used; and only 30% when no cleaning is done.

[0006] 2. The influence of the hole condition: If the performance of the chemical anchor is 100% when the hole is dry, the performance of the chemical anchor is 80% when there is water in the hole, and the performance of the chemical anchor is 100% when the hole is wet.

[0007] 3. Excessive stirring has a significant impact on the bonding strength of chemical anchors. It is necessary to make a embedment depth mark on the bolt. When the bolt reaches the hole surface, the stirring should be stopped in time. Otherwise, if the stirring is excessive for 5 seconds, the bonding strength will only reach 97%; if the stirring is excessive for 10 seconds, the bonding strength will only reach 77%; and if the stirring is excessive for 15 seconds, the bonding strength will only reach 67%.

[0008] 4. The larger the borehole diameter, the significantly lower the pull-out load will be. Therefore, the borehole diameter must be determined according to the data provided by the manufacturer.

[0009] 5. The impact of embedding chemical anchors into concrete through asphalt layers. Because asphalt contains resin-inhibiting agents, it hinders resin hardening. After drilling, it is essential to clean away both concrete dust and asphalt dust.

[0010] Therefore, we propose a mortise and tenon joint method to solve the above problems. Summary of the Invention

[0011] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention. This invention discloses the basic concept of the technical solution adopted to solve the above-mentioned technical problems as follows:

[0012] A mortise and tenon joint curtain wall connection method includes the following steps:

[0013] Step S1: After the steel bars are tied on site, measure and lay out the position of the embedded parts according to the curtain wall drawings. Weld the tenon of the embedded part to the wall with ribbed bolts and weld it to the steel bars of the beam or column. Fill the tenon with filler to prevent concrete from pouring in.

[0014] Step S2: After the concrete construction is completed and the formwork is removed, take out the filler and clean the mortises, and apply a layer of glue to the inside.

[0015] Step S3: First, apply a layer of glue to the inside and then insert a rubber gasket into the tenon of the embedded part;

[0016] Step S4: Insert the second tenon of the curtain wall accessory into the first mortise of the embedded part; adjust the position of the second tenon and the first mortise. If a gap is generated and the gap thickness is greater than 2mm, place a shim in the gap.

[0017] Step S5: A groove is provided on the mortise one, and a wedge is inserted between the groove and the tenon two;

[0018] Step S6: Set the second mortise on the side of the curtain wall fitting away from the wall, clean the second mortise and the tenon shoulder; apply glue to the third tenon of the main keel; connect the third tenon of the main keel to the second mortise of the curtain wall fitting with a tenon and mortise joint.

[0019] Step S7: Tenon 3 is set on the other side of the main keel. Clean mortise 3 before installation;

[0020] Step S8: Connect the fourth tenon of the secondary keel to the third mortise of step S8 using a wooden dowel.

[0021] In a further technical solution, the embedded part includes a first connecting part, a second connecting part, and a clamping plate. The first connecting part has a connecting hole adapted to be connected with a ribbed bolt. The second connecting part has an installation groove adapted to be passed through by a template. The clamping plate is installed on the top of the embedded part and is adapted to abut against the outside of the template.

[0022] In a further technical solution, the mortise is C-shaped and communicates with the upper groove;

[0023] The second tenon of the curtain wall fitting is a lower protrusion, and the top is provided with a lower groove of the same size as the upper groove. The upper groove and the lower groove are suitable for inserting a wedge plug.

[0024] In a further technical solution, the second mortise is adapted to be opened upwards, and the third tenon on the main keel is adapted to be inserted downwards into the second mortise.

[0025] In a further technical solution, the second mortise includes a beveled surface and a latch, the third tenon includes a beveled surface and a latching block, the first beveled surface and the second beveled surface are adapted to abut against each other, and the first latching block is adapted to be inserted into the latch.

[0026] In a further technical solution, the mortise three is provided with a mounting hole one, and the tenon four is provided with a mounting hole two, and a wooden dove is suitable for being inserted between the mounting hole one and the mounting hole two.

[0027] In a further technical solution, two layers of clamping plates are provided at the three positions of the tenon, and each of the two clamping plates is provided with a mounting hole, which is a square hole.

[0028] The tenon four is provided with an upper plate and a lower plate, and the upper plate and the lower plate are rolled up to provide mounting holes two, and mounting holes one and mounting holes two are compatible;

[0029] The length of the upper plate is smaller than that of the lower plate; the upper plate is adapted to be inserted between the two side plates.

[0030] In a further technical solution, the second mounting hole on the lower plate is a blind hole.

[0031] Beneficial effects:

[0032] Existing technologies largely rely on manual installation of expansion bolts to secure numerous connectors for curtain walls. This invention utilizes a mortise and tenon structure, combining this structure with a cast-in-place concrete structure to achieve a stronger connection while avoiding the need for extensive expansion bolt installation. Furthermore, the mortise and tenon joints are cleaned and glued during the implementation steps of this invention, ensuring connection strength and effective implementation.
